Description

The invention relates to a printing unit of a web-fed rotary printing press according to the preamble of claim 1.

By the WO 95/24314 A1 Such a printing unit is known, wherein four double printing units are arranged vertically one above the other and in the region of their double pressure point are horizontally movable relative to each other. For this purpose, the printing units of the same web page are each mounted in a common frame, wherein at least one of the frames is horizontally movable.

The EP 12 64 686 A1 discloses a printing unit with vertically stacked double printing units, wherein the printing cylinder in a middle, and the two inking units are each mounted in outer frame parts. These outer frame members are movable horizontally relative to the central frame member to introduce disk handling devices into the gap as needed.

By the DE 22 34 089 C3 is a Offsetrollenrotationsdruckmaschine known, wherein a plurality of printing units exhibiting wall portion relative to a corresponding counter-pressure cylinder having wall portion is movable. The printing cylinder and associated inking units are mounted as a unit in this wall section movable or removable.

By the DE 43 27 278 C2 a printing unit is disclosed with a construction of a side frame on which transfer and forme cylinder certain Umfangsformates are rotatably mounted and depending on the requirement modular inking a particular of different types of inking can be used.

The US 25 57 381 A shows a flexible set up for various printing methods and number of printing units pressure unit, each of the inking units and the printing cylinder cylinders are placed on each other like a tower and arranged as such movable towards or away from each other. Different types and different numbers of printing units and inking units or inking systems can be used selectively in a standard frame.

By the EP 02 46 081 A2 is a printing unit with a plurality, each having the printing cylinder of a printing unit having units and trained as inking units. The inking units are horizontally adjustable to the printing cylinder for turning on / off and vertical with different printing units, among other things, with different printing units of different print lengths - in contact. The modules having the printing unit cylinders are exchangeable if necessary for units of other printing length.

The DE 102 02 385 A1 shows a drive train between the cylinders of a printing unit with variable printing length, wherein two intermediate wheels are arranged between non-intermeshing cylinder spur gears.

By the EP 06 99 524 B1 Drive trains of printing units are disclosed, wherein in one embodiment, a pairwise drive of the printing unit cylinder is effected by a single motor via meshing spur gears.

In the WO 03/039872 A1 are disclosed printing cylinders, which are driven in pairs in pairs by a drive motor and the two cylinders coupling gear is encapsulated in a separate housing.

The DE 195 34 651 A1 discloses a printing unit with in-plane cylinders, wherein three of four cylinders are mounted linearly movable along the cylinder plane for pressure on or pressure shutdown. The storage takes place in arranged on the frame inner wall guide elements. The cylinders are mounted on the common guide elements in carriers and by pressure medium-operated working cylinder to each other on / off.

In the WO 02/081218 A2 are single linear bearings for two each mounted in carriage transfer cylinder known, wherein an actuator for the carriage can be designed as a cylinder can be acted upon with pressure medium. In order to define an end position for the transverse to the cylinder plane adjusting movement, an adjustable stop is provided.

It is known after EP 1 161 345 B1 the proposal to provide the slender single-circumference cylinder shape not only at the bale ends, but also in the middle with another bearer ring. The forme cylinder prints against a double-sized transfer cylinder and is inked by a single-sized roller. The latter gets color from an approximately double-sized anilox cylinder with chambered doctor blade (dry offset). These four cylinders lie in one plane, with the large cylinders preventing deflection of the two small cylinders. Next, a design with classic inking is shown where two applicator rolls are supplied with ink rollers and Reibzylindern of a large "naked cylinder" with attached siphon inking unit with color for the small forme cylinder. Here are between form cylinder and large nude cylinder outside and in the middle only three support discs, which are supported on bearer rings of the nude cylinder and press against the forme cylinder bearer rings, whereby its deflection is prevented by the compressive forces between the forming and transfer cylinders.

By the WO 03/031179 A2 For example, a printing unit with cylinders of six pages in length and two pages wide is known.

By the WO 02/081213 A2 a printing machine with a form cylinder is known, which has a length for receiving four longitudinally arranged printing plates for newspaper pages in broadsheet format and a scope for receiving a printing plate. The doctrine of the cylinder channels stacked there and, if necessary, the arrangement of the printing cylinder in a plane can there also be applied to printing with six newspaper pages wide printing cylinders.

The invention has for its object to provide cost-effective and easy to manufacture printing units.

The object is achieved by the features of claim 1.

The achievable with the present invention consist in particular that a simple to produce and / or easy-to-use printing unit is created at the same time high print quality.

By dividing in one embodiment side racks good accessibility, a contribution to possible modularity and a lower height is created.

By using linear guides for the printing cylinder, an ideal installation position of the cylinder is achieved with respect to possible cylinder oscillations. In addition, small positioning paths are realized by the cylinder bearing in linear guides and therefore no synchronous spindle required. The complex installation of three-ring bearings is eliminated.

The same arranged on the side frames, the same non-penetrating cylinder bearings allow side employees without specific bearing bores. The racks can be executed independently of format. A cylinder unit can be used together with preset storage on site easily in the frame walls. Due to the module size (cylinder plus storage units), which only covers one cylinder, cylinder formats of different sizes can be used and, if necessary, combined.

By one or more of the above, created for the modularity conditions, there is a considerable savings potential, since the number of individual assemblies is increased both in construction and in production.

Since the drives of the printing cylinder and / or the individual inking units are designed with individual motors or as a closed gear modules, lubricant z. B. only in the already prefabricated function modules available.

The storage inside of the side frames allows in addition to the simple installation and the reduction of cylinder pin, which has a vibration-reducing effect.

The aforementioned design of the linear bearings with movable stops allows pressure-related adjustment of the cylinder and further an automatic basic setting - for a new configuration, a new blanket, etc.

In one embodiment of a modular handling machine, a simple plate change is possible for different formats.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below.

A printing machine, z. B. web-fed rotary printing press, in particular a multi-color web-fed rotary printing press, has a printing unit 01, in which a web of material 02, short web 02 on both sides simply or in particular successively multiple, z. B. here four times, or several tracks at the same time one or more times are printable. The printing unit 01 has a plurality of (in the present case four) vertically stacked double printing units 03 for the two-sided printing in Gummigegen rubber operation. The double printing units 03 - shown here in the form of bridge or n-printing units - are each formed by two printing units 04, which each have a cylinder 06 formed as a transfer cylinder 06 and cylinder 07 as a forme cylinder; 07, z. B. printing cylinder 06; 07, and in each case have an inking unit 08 and in the case of wet offset printing additionally a dampening unit 09. In each case between the two transfer cylinders 06 a (double) pressure point 05 is formed in Anstelllage. The aforementioned components are designated only at the top double printing unit 03 of Figure 1, wherein the stacked (double) printing units 03; 04, however, essentially - are executed identically - in particular in the embodiment of the relevant features of the invention. The double printing units 03 can - as well as the advantageous feature of the linear arrangement described below - just as well be embodied contrary to the illustration in FIG. 1 as an upwardly opening U unit.

In advantageous embodiments, the printing unit 01 has one or more of the following features, depending on the requirement, the type of machine, the technology used and / or the level of expansion. The printing unit 01 or the double printing unit 03 is / are z. B. in the middle, ie in the field of double pressure point (s) 05, operationally divisible run and / or the inking units 08 (and possibly dampeners 09) are formed as already several rolls having modules and used as pre-assembled modules in the printing unit 01 and / or there are printing cylinder 06; 07 different diameter without requirement of bearing bores in the side frame mounted and / or the Cylinder bearings are force-controlled adjustable in linear bearings and / or the axes of rotation of the printing cylinder 06; 07 in print-on are essentially lying in a common plane. In addition (or possibly as an independent version), the modularity by the special, coupled via two intermediate wheels pairwise drive connection of a printing couple cylinder pair or individual drives of the cylinder 06; 07 are supported advantageous. This also applies in an advantageous embodiment for the mechanical independence of the drive of the inking unit 08 and possibly dampening unit 09 from the drives of the printing cylinder 06; 07th

In principle, one or more of the mentioned features are also to be understood advantageously as printing units which do not have printing units 03 designed as double-printing units in the rubber-against-rubber printing, but have printing units 03 working only in straight printing. The transfer cylinder 06 of a printing unit then interacts with a counter-pressure cylinder. In particular, in the modular concept, this can optionally be provided, wherein instead of the two cylinders 06; 07 of the second printing unit 04 and the inking unit 08 then only an impression cylinder is used. For the arrangement within the side walls then to the other cylinders 06; 07 below apply.

In the following figures 2 and 3, an advantageous embodiment of the printing unit 01 is shown, which - in principle independent of the also shown there and described in more detail below modular structure of the printing units 04 and / or only for the upper double printing unit 03 indicated by way of example storage units 14 (see Fig. 18) - in the region of their double pressure point (s) 05, operational, ie for setup and maintenance purposes (in contrast to disassembly or disassembly), is divisible executed. The two separable parts (including cylinder 06; 07, inking units 08 and, if present, dampening units 09) are referred to below with partial pressure units 01.1 and 01.2.

For this purpose, the printing cylinder 06; 07 of the plurality of (four) stacked double printing units 03 rotatable in or on a right and a left frame or wall section 11; 12 stored in such a way that the two printing cylinder 06; 07 of the same printing unit 04 the same frame or wall section 11; 12 is assigned. Preferably, the printing cylinder 06; 07 more, in particular all the web 02 on the same side printing printing 04 on the same frame or wall section 11; 12 stored. The printing cylinder 06; 07 can in principle only one-sided, d. H. be stored flying on only one end frame frame sections 11. Preferably, however, each partial pressure unit 01.1; 01.2 two front side to the cylinders 06; 07 arranged frame sections 11; 12 provided. The two separable parts are hereinafter referred to as partial pressure units 01.1 and 01.2, which the respective frame sections 11; 12 and printing units 04 (printing cylinder 06, 07 and inking units 08) have.

The partial printing units 01.1; 01.2 are along a direction perpendicular to the axis of rotation of the cylinder 06; 07 movable towards or away from each other by preferably one of both spatially fixed (here partial pressure unit 01.1), d. H. for example, on a floor 13 of the printer room, a fixed space carrier 13, a mounting plate 13 or a mounting frame 13 for the printing unit 01 stationary, and the other (here partial printing unit 01.2) movable relative to the bottom 13 or support 13 or mounting plate 13 or mounting frame 13th (hereinafter carrier 13) is stored.

For this purpose, the outer frame sections 12 in mutually corresponding, in non-illustrated bearing elements of the frame portion 12 and the carrier 13, z. B. together a linear guide 15 forming, stored. These can be designed as running in rails rollers or as a sliding or rolling body mounted mutually associated linear guide elements.

Preferably, the wall sections 11; 12 are formed so that they are formed in their operating position A (Fig. 2) on its side facing each other in pairs substantially complementary to each other form and together at their dividing lines or lines of attack nevertheless form a substantially closed side front.

3 shows a maintenance position B of the printing unit 01 (without the bearing units 14 indicated in FIG. 2), the relative position of the partial printing units 01.1; 01.2 each other by moving the frame sections 12 is effected. The relative position can in principle be achieved in another embodiment by both partial pressure units 01.1; 01.2 or their frame sections 11; 12 are movably mounted.

Shaping and transfer cylinder 07; 06 are in a first, in Figs. 1 to 3 previously shown format design preferably with a bale width of at least four, z. B. four or for particularly high product output six, juxtaposed standing printed pages in newspaper format, especially in broadsheet format formed. Thus, a double-width web 02 side by side with four or a three-width web 02 printed side by side with six newspaper pages, and the forme cylinder 07 corresponding to four or six printing plates, in particular aligned with their ends to each other, adjacent to each other. In a first, in Figs. 1 to 3 previously shown advantageous format design, the cylinder 06; 07 on a circumference, which essentially corresponds to two consecutively arranged printed pages in a newspaper format.

In the embodiments of the printing unit 01 with form cylinders 07 double-sized format (two newspaper pages in the scope behind each other), this advantageously has two circumferentially offset by 180 ° to each other channels for receiving the printing plates, which preferably over the entire effective ball length continuously are formed. The forme cylinder 07 can then be equipped with four or six printing forms side by side and two printing plates in succession.

The transfer cylinder 06 has a double large format (two newspaper pages in the scope behind each other) in one embodiment z. B. only one channel for receiving one or more juxtaposed blankets, which is preferably formed continuously over the entire effective bale length. The transfer cylinder 06 can then be equipped with a continuous over the bale length and extending over substantially the full extent or with two or three over substantially the full extent reaching blankets side by side. In another embodiment of the double-sized transfer cylinder 06, this two or three blankets can have side by side, wherein the respective adjacent to each other are offset by 180 ° in the circumferential direction. These mutually offset blankets can be held in two or three channel sections, which are also adjacent to each other in the longitudinal direction of the cylinder 06, the adjacent channel sections in the circumferential direction, however, are mutually offset by 180 °.

As already indicated in FIGS. 2 and 3, in an advantageous embodiment of the printing unit 01, the inking units 08 or cylinder units 17 formed of bearing units 14 and the respective cylinder 06, or preferably both the inking units 08, are initially independent of the part or separability as well as the cylinder units 17 as modules, d. H. designed as structurally considered pre-assembled units.

The running as modules inking 08 have z. B. a separate frame 16 and a frame structure 16, in which several functional parts, here at least three, especially all rollers and a color source or ink supply (chamber doctor blade, ink fountain, applicator nozzles, etc.) of the inking unit 08, even without connection to the side frame 11; 12 of the printing unit 01, already their firmly defined position to each other obtained and, for example, pre-assembled and a total of the printing unit 01 can be introduced. The frame construction 16 or the frame 16 can be embodied, in particular, as two side frames which are arranged at the ends on the rollers and which are interconnected, for example, by at least one traverse (not shown) and / or a base. The functional parts of the module receiving frame 16 is fixed during assembly (cohesively or fomschlüssig solvable) with the side frame 11; 12 of the printing unit 01 connected. If the printing unit 01 is designed to be partially or separable in the manner described above, the inking units 08 designed as modules will be assembled on assembly with the respective frame or wall sections 11; 12 - cohesive (welding) or positive releasable (screw) - connected. The total side frame on one side of the printing unit 01 or a total side frame of a partial printing unit 01.1; 01.2 then sets in several pieces - a cylinder 06; 07 receiving side frame 11; 12 and partial sub-frames of the inking units 08 comprising - together. Detachable here means no operational solubility but only a disassembly with regard to a disassembly of the printing unit 01 or a removal / replacement of the inking unit 08.

As a cylinder units 17 running modules (see below to Fig. 17 and 18) have z. B. a cylinder 06; 07 with pin 63; 64 and one already on the pin 63; 64 pre-loaded (biased and / or preset) storage unit 14 on. Bearing unit 14 and cylinder 06; 07 get before their insertion into the printing unit 01 their firmly defined position to each other and are collectively in the printing unit 01 introduced.

FIG. 4 illustrates a system of a modular printing unit 01, which, however, can basically be designed to be both divisible (as illustrated) and indivisible. In the latter case, that would be the cylinder 06; 07 receiving side frame 11; 12 not in two parts but one-piece and fixed space in the printing arranged. Advantageously, however, the divisible variant as shown.

In the case of the non-divisible variant, for example, two front side to the cylinders 06; 07 arranged side frames 11; 12 together with the stationary carrier 13 (or mounting plate 13 or mounting frame 13) and at least one (better two) connecting the two sides above a middle height traverse (not shown for this case) form a backbone 18 for the printing unit 01.

For the divisible version of the skeleton 18, for example, by the lower carrier 13, the two each stationary fixed frame sections 11, per printing press side at least one support 19, a fixed space arranged frame portion 11 and the support 19 connecting upper carrier 21 per press side and at least one ( better at least two) the two sides above a middle height connecting traverse 22 (only shown in broken lines). The frame sections 11; 12 may be designed as substantially continuous wall sections in each case in one piece and flat or for the purpose of a lighter construction and / or better accessibility of the units, as shown, each be kept slim and possibly each side frame for stabilization with additionally one or more vertically supporting supports ( not specifically referenced).

This "empty" skeleton is now with printing cylinders 06; 07 and inking 08 different configuration configurable or set up.

As also shown in Fig. 4, as a transfer cylinder 06, a transfer cylinder 06a with a circumference of two stationary printed pages, especially newspaper pages in broadsheet format, (double size) or a transfer cylinder 06b with a circumference of a print page, especially newspaper page in the broadsheet Format (simply large) to be used. Likewise, the assembly with cylinders 07a a circumference of two stationary pages, especially newspaper pages, or simple scope (form cylinder 07b), ie a print page, in particular newspaper page in broadsheet format, on the periphery possible. In principle, any combination of forming and transfer cylinders 07; 06 with an integral peripheral ratio of form to transfer cylinder 07; 06 to each other, z. B. 1: 1, 1: 2, 2: 1, 3: 1, 1: 3, 3: 2, 2: 3, but preferably with a forme 07, which is equal to or equal to the transfer cylinder 06.

In the embodiments of the printing unit 01 with form cylinders 07 simply large format (a newspaper page in the scope) has this advantageously in the circumferential direction considered a channel for receiving the printing plates, which is preferably formed continuously over the entire effective bale length. The forme cylinder 07 can then be equipped with four or six printing plates next to each other.

The transfer cylinder 06 has a simple large format (a newspaper pages in the scope) in one embodiment z. B. only one channel for receiving one or more juxtaposed blankets, which is preferably formed continuously over the entire effective bale length. The single-circumference transfer cylinder 06 can then be equipped with a continuous over the bale length and over substantially the full extent reaching or with two or three over substantially the full extent reaching blankets juxtaposed.

In embodiments where a simply large forme cylinder 07 interacts with a double-sized transfer cylinder 06, the one mentioned in connection with the doubly large transfer cylinders 06 and the simply large forme cylinders 07 can advantageously be used together.

Also, the optional configuration with (eg, single large or double-sized) cylinders 06; 07 with scopes for different printed page formats, eg. As newspaper formats, with divergent circumferences possible. Thus, the sizes of double-sized cylinders 06a; 07a between 840 and 1300 mm, in particular 860 to 1120 mm, and that of the single-cylinder 06b; 07b corresponding to 420 to 650 mm, in particular 430 to 560 mm or even between 430 to 540 mm. With the cylinder unit 17 described in more detail below, this modular construction is particularly favored, since for this purpose the exact position and geometry of the cylinders 06; 07 bearing bores for the accurate fit of three- or four-ring bearings with z. B. eccentrics in the side frame 11; 12 must be provided.

In Fig. 5, the printing unit 01 is exemplified by cylinders 06a; 07a double circumference executed. When equipped with simple large cylinders 07b these can for reasons of increased stability (as below to Fig. 7, 9, 13) with double-size transfer cylinders 06a or space-saving with equally simple transfer cylinders 06b cooperate.

Particularly advantageously, it is possible - in principle, independently of the divisibility of the printing unit 01 and / or the modular use of cylinder units 17 - to execute the printing unit 01 in a modular manner with inking units 08 of different types depending on the customer's requirements. The various types of inking can, as shown in Fig. 4 Short inking 08.1, single roll inking 08.2 z. B. with two Reibzylindern (eg., From the newspaper printing) or roller inking 08.3 with two color trains and z. B. three Reibzylindern (eg., From the commercial printing).

The inking unit 08, which is designed as a short inking unit 08.1 of a first variant (FIG. 6a), has a central roller 26 with scrapers or cups, for example a bottle. Example, an anilox roller 26, which relates the color of an inking device 27, in particular a chambered doctor blade 27 (or even a roller, not shown from an ink fountain) and at least one, preferably at least two, roller (s) 28, z. B. applicator rollers 28, in particular with a soft surface, emits to the printing plate of the forme cylinder 07. Advantageously, the central roller 26 with two other soft rollers 29, z. B. paint or applicator rollers 29 together. To even out the Color distribution acts depending on an axial roller 31, z. B. iridescent friction roller 31 (preferably hard surface) with one applicator roller 28 and the adjacent ink rollers 29 together. The inking device 27 obtains its color, for example, from a paint reservoir 32, in particular via a pumping device, not shown, in which excess paint can also drain.

In another embodiment, as explained in the development to Fig. 30, directly the gear 150 with drive motor 121 without angle and / or offset compensating coupling 148 can be coupled to the shaft 78. In this embodiment is the drive motor 121 not fixed to the frame, but arranged cylinder-tight and is connected to the cylinder 06; 07 moved.

On a drive side opposite side of the cylinder 06; 07, in particular of the cylinder 07 designed as a forme cylinder 07, the pin 64 is preferably provided with a device for axially moving the cylinder 07, d. H. with a side register drive 201, coupled (Figure 36). The example in the manner of Figure 18 with the pin 63; 64 connected shaft 78, via a bearing 202, z. B. thrust bearing 202 with an axial drive 203, 204, 206, 207 connected. The axial drive comprises a spindle 203, in particular with at least one threaded portion 205, a rotatably connected to the spindle 203 spur gear 204, a pinion 206 and the pinion 206 driving motor 207. The threaded portion 205 acts with a bearing block fixed internal thread 208, z. B. an internal thread 208 of a bearing block 74 connected to the pot 209, and causes the rotation of the spindle 203 an axial movement thereof together with the shaft 78 (via the thrust bearing 202) and pin 63; 64. The thrust bearing 202 allows relative rotation between the shaft 78 and spindle 203, but is formed with respect to an axial direction of the cylinder 07 pressure and tension. This is done via a arranged on the shaft 78 disc 211, which is supported on both sides, for example via rolling elements 212, wegbegrenzt by spindle-fixed stops 210 in both directions. An adjustment of the page register is now carried out by the motor 207 via a control device, not shown. In this case, the motor 207 may either itself via a -. previously calibrated accordingly - motor-internal position feedback feature, or there is a position feedback to the controller via a sensor, not shown, for. B. a suitably calibrated Drehpotentiomerter which is coupled to a rotating member of the axial drive.

The formation of the linear bearings 70 in such a way that the cooperating bearing elements 72; 73 both on the assembly storage unit 14 - and not a part of the side frame 11; 12 of the printing unit 01 - are provided, allows pre-assembly and pre-adjustment or adjustment of the bearing voltage. The advantageous arrangement of the two bearing block 74 encompassing linear bearing 70 allows a backlash-free setting, as opposed to the two linear bearings 70 in such a way that the bearing preload and the bearing forces an essential component in a direction perpendicular to the axis of rotation of the cylinder 06; 07 learn or record. The linear bearings 70 are thus adjustable in the direction to which it is at play-free positions of the cylinder 06; 07 also arrives.

Since the cylinder 06; 07 together with pin 63; 64 and bearing unit 14, the frame wall 11; 12 not penetrate, these are already pre-assembled and the bearings (radial bearings 71 and linear bearings 70) preset or correctly biased as a module cylinder unit 17 in the printing unit 01 used. The term "non-penetration" and the above definition with respect to the inside width L should be understood in a broader sense to mean that, at least in the region of the intended end position, the cylinder 06; 07 and at least on a continuous path from a frame edge to the location of the end position such a "non-penetration" is present, so that the cylinder unit 17 of an open, between the two end-side side frames 11; 12 lying side without tilting, d. H. be brought in a position with the frame plane perpendicular axis of rotation to the end position and there are arranged between the two frame inner walls, in particular attached to the frame inner walls, can. This is z. Example, even if possible on the inside while Angussteile or other surveys are provided, a named continuous assembly path is provided, however.

The bearing units 14 are in the manner on the inner walls of the Seitengestellt 11; 12 arranged that the cylinder 06; 07, in particular their bearing units 14 on the cylinder side by the side frame 11; 12 are supported, which has static and mounting advantages.

The recognizable in Fig. 18 and 19 linear bearings 70 (72, 73) thus each have Pairings of corresponding, cooperating bearing means 72 and 73 or their guide or effective surface areas, as sliding surfaces (not shown) formed or arranged therebetween rolling elements 65, on. As shown in FIG. 42, in a preferred embodiment at least one of the two advantageous two linear bearings 70 of a bearing unit 14 is designed such that the two corresponding bearing means 72 and 73 each have at least two guide surfaces 72.1; 72.2; 73.1; 73.2, which lie in two mutually inclined planes. The two guide surfaces 72.1; 72.2; 73.1; 73.2 (or their planes E1, E2) of the same bearing means 72; 73 are z. B. V-shaped to each other, for. B. with an intermediate angle between 30 to 60 °, in particular between 40 and 50 °, inclined. The two guide surfaces 73.1; 73.2; 72.1; 72.2 of the cooperating bearing means 73; 72 are complementary in shape. At least one of the two pairings of cooperating guide surfaces 72.1; 72.2; 73.1; 73.2 is parallel to a plane E1, which has a component not equal to zero in the radial direction of the cylinder axis and thereby prevents the degree of freedom of movement in a purely axial direction of the cylinder. Preferably, both pairings lie to planes E1; E2, which both have a component not equal to zero in the radial direction of the cylinder axis, but in reverse inclination against the cylinder axis and thereby prevent the degree of freedom of movement in both axial directions of the cylinder. A section line of the two planes E1; E2 is parallel to the direction S

Is, as can be seen in Fig. 18, the bearing block 74 between the two, two pairs of co-operating guide surfaces 72.1, 73.1 and 72.2; Contained 73.2 having linear bearings 70, biased in particular with a bias, the bearing block 74 only a single degree of freedom of movement along the direction of adjustment S on.

The inclined active or guide surfaces 72.1; 72.2; 73.1; 73.2 are arranged such that they are a relative movement of the bearing parts of the linear bearing 70 in the axial direction the cylinder 06; 07, ie the bearing is "tied off" in the axial direction.

Preferably, the linear bearings 70 both a cylinder 06; 07 frontally associated bearing units 14 two mutually arranged pairs of cooperating guide surfaces 72.1; 72.2; 73.1; 73.2. In this case, however, advantageously at least one of the two radial bearings 71 of the two bearing units 14 a slight bearing clearance .DELTA.71 in the axial direction.

In FIGS. 18 and 42, the guide surfaces 72.1; 72.2 of the frame-fixed bearing means 72 of the linear guide 70 in the pin 63; 64 facing half space. The frame-fixed bearing means 72 encompass here the bearing block 74 arranged between them. The frame-fixed guide surfaces 72.1; 72.2 of the two linear bearings 70 thus partially surround the guide surfaces 73.1; 73.2 of the bearing block 74 with respect to an axial direction of the cylinder 06; 07th

For correct placement of the bearing units 14, and cylinder units 17 together with bearing unit 14, mounting aids 89, z. B. dowel pins 89 in the side frame 11; 12 may be provided, to which the bearing unit 14 of the fully assembled cylinder unit 17 is aligned, before they by releasable retaining means 91, z. B. screws 91, or even cohesively by welding to the side frame 11; 12 are connected. For the setting of the bearing preload in the linear bearings 70, which can be adjusted before insertion into the printing unit 01 and / or post-insertion, corresponding means 92, e.g. B. clamping screws 92 may be provided (Fig. 18). Preferably, the bearing unit 14 - at least to the cylinder side - by a cover 94 largely protected against contamination or even encapsulated executed as a unit.

In Fig. 18 is schematically the cylinder 06; 07 with pin 63; 64 and a pre-assembled Storage unit 14 marked. This module can thus be preassembled between the side frames 11; 12 of the printing unit 01 used for easy installation and attached to designated locations. Preferably for a modular design, the bearing units 14 for forming and transfer cylinders 07; 06 - if necessary, except for the permitted operational size of the travel - identical design. Due to the pre-assembled design, the effective inner surface of the radial bearing 71 and the outer effective lateral surface of the pin 63; 64 be cylindrical instead of tapered, since both the assembly of the bearing unit 14 on the pin 63; 64 as well as the setting of the bearing clearance outside the printing unit 01 can be done. The storage unit 14 can be shrunk, for example.

The mountable as a whole unit (storage unit 14) is advantageous in the manner of an optionally partially open housing of z. B. the carrier 76, and / or z. Example, a frame (in Fig. 19 without reference numerals, for example, the four the bearing unit 14 to all four sides outwardly bounding plates) and / or z. The cover 94 (Figure 18). Within this housing or this frame of the radial bearing 71 having bearing block 74, the linear guides 70 and in an advantageous embodiment, for. B. the actuator 82 and the actuators 82 housed.

The frame-fixed bearing elements 72 are arranged substantially parallel to one another and define a positioning direction (FIG. 19).

Pressing is effected by moving the bearing block 74 in the direction of the pressure point by means of a force F applied to the bearing block 74 by at least one actuator 82, in particular by a force-controlled or force-defined actuator 82, by means of which a defined resp . definable force F in print-on direction on the bearing block 74 can be brought (Fig. 19). The decisive for the color transfer and thus the print quality, among other line force in the Nippstellen is therefore not by a travel, but by the balance of power between the force F and the between the cylinders 06; 07 resulting line force F _L and the resulting equilibrium defined. In a first, not specifically illustrated embodiment cylinder 06; 07 employed in pairs by the bearing block 74 is acted upon by the correspondingly set force F on the / the Aktror (s) 82. Are several (eg three or four) in direct succession adjacent pairs cooperating cylinders 06; 07 executed without a possibility for fixing or limiting the travel S with a purely force-dependent control mechanism, it is indeed a. With respect to the required pressures (line forces) adjusted system off and subsequently correct again, make a basic setting is due to the z , T. overlapping reactions difficult.

For basic adjustment of a system (with corresponding elevators etc.), it is therefore provided in an advantageous embodiment that at least the two middle of the four cylinders 06 - or in other words, at least all of the two outer cylinders 07 different cylinder 06 at least during a period of time Setting in a defined position, advantageously in the Anstelllage found by the equilibrium of forces, can be fixed or at least wegbegrenzbar.

Particularly advantageous is an embodiment, wherein the bearing block 74 - even during operation - at least in one direction away from the pressure point against a force, for. B. spring force, in particular a definable force, is movably mounted. This is - in contrast to the pure travel limit - on the one hand, a maximum line force when working together cylinder 06; 07 defined, and on the other hand a yielding, for example, in a web break with subsequent winder on the cylinder 06; 07, allows.

At a pressure point 05 facing side, the bearing unit 14 - at least during the adjustment - a movable stop 79, which limits the travel to the pressure point 05 out. The stopper 79 is in the way Locally variable that the stop surface 83 effective as a stop along the adjustment direction is variable at least in one area. It is thus an adjustment device (adjustable stop 79) provided in an advantageous embodiment, by means of which the position of a pressure near the end position of the bearing block 74 is adjustable. For Wegbegrenzung / adjustment serves z. B. a wedge drive described below. The placement of the stop 79 can basically be done manually or via an actuator 84 (see below). Next, in an advantageous embodiment, a holding or clamping means not shown in Fig. 18 and 19 is provided by means of which the stop 79 can be set in the desired position. Next is at least one resilient element 81, z. B. spring element 81, which applies a force F _R from the stop 79 in a direction away from the bearing block 74. Ie. the spring member 81 causes pressure-off in the event that the bearing block 74 is not prevented from moving in any other way. A pressure-on points done by moving the bearing block 74 in the direction of stop 79 by at least one actuator 82, in particular a force-controlled actuator 82, by means of which for employment either a defined or definable force F in print-on direction on the bearing block 74th can be brought. If this force F is greater than the restoring force F _{R of} the spring elements 81, an adjustment of the cylinder 06 takes place with a corresponding spatial configuration; 07 to the adjacent cylinder 06; 07 and / or a hiring of the bearing block 74 to the stop 79th

Ideally, the applied force F, the restoring force F _R and the position of the stop 79 is selected such that no substantial force ΔF is transmitted between the stop 79 and the abutment surface of the bearing block 74 in an abutment position, for example | ΔF | <0.1 * (F-F _R ), in particular | ΔF | <0.05 * (F-F _R ), ideally ΔF | ≈ 0. In this case, the contact force between the cylinders 06; 07 substantially determined by the voltage applied by the actuator 82 force F. The decisive for the color transfer and thus the print quality, inter alia, line force in the Nippstellen is therefore not primarily by a travel, but in quasi-free stop 79 by the force F and defines the resulting equilibrium. Basically, after finding the basic setting with the appropriate forces F, a removal of the stop 79 or a corresponding fixation, which is effective only during the basic adjustment, would be conceivable.

In principle, the actuator 82 can be embodied as any desired actuator 82 applying a defined force F. Advantageously, the actuator 82 is designed as actuatable by pressure medium actuating means 82, in particular as a piston 82 movable by a fluid. Advantageous in terms of possible tilting is the arrangement of several, here two, such actuators 82. As the fluid is preferably because of their incompressibility, a liquid, eg. As oil or water, used.

To actuate the actuators 82, which are designed here as hydraulic pistons 82, a controllable valve 93 is provided in the bearing unit 14. This is performed, for example, electronically controlled and provides the hydraulic piston 87 in a position without pressure or at least to a lower pressure level, while in another position of the force F conditional pressure P is applied. In addition, a non-designated leakage line is provided here for safety.

In order to avoid too large An- / Abstellwege and still hedge Bahnwickler, can on the remote printing side of the bearing block 74 a travel limit by a mobile, force-limited stop 88 as overload protection 88, z. B. spring element 88 may be provided, which in the operational pressure-Ab, ie the piston 82 are relieved and / or retracted, although serve as a stop 88 for the bearing block 74 in pressure-off position, in the case of a railway winder or other excessive forces but gives way from the point of pressure 05 and releases a larger path. A spring force of this overload protection 88 is therefore selected to be greater than the sum of the forces from the spring elements 81. When operational on / off is therefore only a very short travel, z. B. only 1 to 3 mm, providable.

The stop 79 in the illustrated embodiment (FIG. 19) is designed as a wedge 79 movable transversely to the direction of adjustment S, the position of the respective effective stop face 83 varying along the direction of adjustment S as it moves. The wedge 79 is supported for example on a carrier-fixed stop 96.

The executed here as a wedge 79 stop 79 by an actuator 84, for example, a druckmittelbetätigbares adjusting means 84 such as a pressure medium actuated piston 84 in a working cylinder with (double-acting) piston via a z. B. designed as a piston rod 85 transmission member 85 or by an electric motor via a designed as a threaded spindle transmission member 85, movable. This actuator 84 can either be effective in both directions or, as shown here, be designed as a one-way reactor, which operates against a return spring 86 when activated. The force of the return spring 86 is from o.g. Reasons (largely force-free stop 79) chosen so weak that the wedge 79 is held only against gravity or vibration forces in its correct position.

In principle, the stop 79 can also be designed in another way (for example as a plunger adjustable and fixable to the adjusting direction, etc.) in such a way that it can be varied in the adjusting direction S and-at least during the setting process-fixed stop surface 83 for the movement of the bearing block 74 in the direction of pressure point 05 forms. In a non-illustrated embodiment, a setting of the stopper 79, for example, directly parallel to the direction of adjustment S by a drive means, for example, a pressure medium actuated cylinder with (double-acting) piston or an electric motor.

Fig. 20 shows on executed as a double printing unit 03 printing unit 03 schematically per cylinder 06; 07 arranged on the side frame 11 storage unit 14. In an advantageous embodiment shown here form in pressure-on position the Rotation centers of the cylinders 06; 07 an imaginary connecting line or plane E (hereinafter referred to as "linear double printing"). The plane E and the incoming or outgoing web 02 preferably enclose an interior angle α deviating from 90 °, between 75 and 88 °, in particular between 80 and 86 °. The storage unit 14 of the transfer cylinder 06, in particular all cylinder 06; 07, are arranged in the mounted state in the embodiment shown in Fig. 20 on the side frame 11 such that their actuating directions S -. B. reasons of a force-defined pressure-on setting (see below) - with the connection plane E a maximum angle of 15 ° includes, z. B. an acute angle β of about 2 ° to 15 °, in particular 4 to 10 ° form each other Particularly advantageous in terms of assembly, this arrangement, when the adjustment direction S is horizontal and the web 02 is substantially vertical.

In a modified embodiment of an angular (n or u printing unit 03) arranged double printing unit 03 is under the plane E 'the connection plane of the pressure point 05 forming cylinder 06 and level E "the connection plane between the forming and transfer cylinder 07, 06 are understood and the above to the angle β on the direction of adjustment S at least one of the pressure point 05 forming cylinders 06 and the forme cylinder 07 and the plane E 'and E "are related.

One of the pressure point 05 forming cylinder 06 can also be stationary and operationally not adjustable (but possibly adjustable) in the side frame 11; 12 may be arranged, while the other along the adjustment direction S, is movably mounted.

A for switching on / off operational travel along the direction of adjustment S between pressure-off and pressure-on position is z. B. in the transfer cylinder 06 at 0.5 to 3 mm, in particular at 0.5 to 1.5 mm, and the forme cylinder 07 at 1 to 5 mm, in particular at 1 to 3 mm.

When executed as a linear double printing 03, the plane E against the plane of incoming and outgoing train 02 z. B. an angle α by 75 ° to 88 ° or 92 to 105 °, preferably umα 80 to 86 ° or 96 to 100 °, each on one side of the web (or 96 to 100 ° bzw.α 80 to 86 ° the other side of the track) inclined.

In another embodiment, shown in FIG. 21, the bearing units 14 of the transfer cylinder 06, in particular of all cylinders 06; 07, arranged in the mounted state on the side frame 11 such that their adjusting directions S coincide with the connecting plane E, d. H. form an acute angle β of about 0 °. All adjustment directions S coincide therewith and are not spaced apart.

Irrespective of the tendency of the travel paths to plane E or E 'or E "(small inclination or not) as shown in FIGS. 20 and 21, an advantageous procedure for adjusting the cylinders 06, 07 is shown in the schematic example of FIG (here to distinguish between left and right printing unit with the additions "1" and "2") or their pressure-on position shown:

First, a first, the pressure point 05 with defining cylinder 06.1, z. B. transfer cylinder 06.1, in its position in pressure-on position (i.e., actuators 82 are active) within the printing unit 01 and the web 02 by placing the stops 79 (to both end faces) aligned. As indicated here, this can be done by an actuator 84 (adjusting screw), which can be actuated manually here, for example. Here, a pressure point defining so-called. "0-position" is determined.

Subsequently, when released stop 79 of the associated forme cylinder 07.1, ie the stop 79 has been z. B. previously removed by pulling up, and still activated pressure-on position of the transfer cylinder 06.1, ie activated actuators 82 of the transfer cylinder 06.1, for the pressure-on position between form and transfer cylinder 07.1; 06.1 desired force F acted upon. This is done here by Actuation of the actuators 82 of the forme cylinder 07.1 with the desired contact pressure P. If an adjustable stop 79 is also provided on the bearing unit 14 of the first forme cylinder 07.1, this stop 79 can now be substantially force-free in contact with the corresponding stop surface of the bearing block in a first variant 74 are brought to the first forme cylinder 07.1.

When the pressure on position is activated (i.e., in each case the force exerted in the direction of the pressure point 05) of the two first cylinders 06.1; 07.1 and pressure-down of the second forme cylinder 07.2 is, during or after the stop 79 of the third cylinder 06.2 is released or was, the second transfer cylinder 06.2 or its bearing block 74 with the desired force (pressure P) for the pressure on -Stellung applied, and brought on reaching the equilibrium of the stop 79 substantially force-free in contact with the corresponding abutment surface of the bearing block 74. In this context, before, during or after, if not already in o. G. Variant takes place, the stop 79 of the first forme cylinder 07.1 be brought into contact with the associated bearing block 79.

In a final step - with free or previously released stop 79 - the second forme cylinder 07.2 or its bearing block 74 brought into pressure-An, while also the associated transfer cylinder 06.2 is also in pressure-on. After reaching stationarity is - if a stop 79 is provided there - even at the second forme cylinder 07.2 this stop 79 spent substantially force-free in contact with the corresponding stop surface of the bearing block 74.

In this way, an optimally tuned for the printing process setting of the cylinder 06; 07 of the double printing unit 03 takes place.

In Fig. 23, an embodiment of an interconnection of a pressure medium supply - suitable for implementing the above-mentioned procedure - shown. An outward open or closed fluid reservoir 101 is at a pressure level of a pressure P _L (eg ambient pressure) which is lower than a pressure P corresponding to the restoring force F _{R of} the spring elements 81 of a bearing unit 14. The pressure medium (fluid) is passed through a compressor 102, z. B. a pump or turbine, compressed to a pressure level of a pressure P _H , which corresponds to at least the pressure required for the pressing force F P. In order to keep pressure fluctuations as low as possible by removing pressure medium, compressed fluid can advantageously be stored in a pressure reservoir 103 on the pressure P _H. From the pressure medium branch having the high pressure P _H , a supply path 106 is depressurized via an actuator 104, in particular an adjustable pressure reducer 104, the pressure level of which through the pressure reducer 104 is reduced to the pressure P (corresponding force F, if appropriate) which is suitable for the pressure on position ., Taking into account the restoring force F _R and possibly force .DELTA.F) is set. In an embodiment not shown, two different pressure levels P (eg P _DS for the contact pressure at the pressure point and P _DW for the contact force between the printing cylinder 06, 07) can also be provided via two adjustable pressure reducers 104 in two supply lines 106.

The inputs of the already mentioned in connection with FIG. 19 valves 93, in particular multi-way valves, per stellbarem cylinder 06; 07 are now connected to the supply path 106 of the pressure P. At two levels above the inputs of the movable transfer cylinder 06 associated valves 93 z. B. with the pressure P _DS and the inputs of the form cylinders 07 associated valves 93 connected to the pressure P _DW . The outputs of the valves 93 are connected to the fluid reservoir 101.

Positioning of the stops 79, which are not movable in a purely manually movable manner, via the actuating means 84, which are in the form of pressure-actuable actuators 84, takes place, for example, either advantageously via a separate supply section 107 (shown) providing a pressure P _S or if necessary integrated into the above-mentioned pressure levels. As shown in FIG. 23, the pressure P _s providing fluid as a gaseous pressure medium, for. As compressed air, be provided in an open system. An input of a valve 108 connected to the associated actuator 84 is connected to the supply path 107, wherein depending on the configuration of the actuator 84 (double-acting in both directions or acting only in one of two possible directions) one or two outputs of the valve 108 with one or two inputs of the actuator 84 are connected.

In a further development shown in FIG. 23, an actuatable retaining means 111, for example a plunger, is also provided for fixing the stop 79, by means of which the stop 79 can be held in its essentially force-free position without being relieved of pressure to change its position. Also, this holding means 111 may be connected for the purpose of actuation or release via corresponding lines and other valves 112 to the pneumatic supply line 107. In the example shown, the retaining means 111 is designed to selectively clamp the stop 79 (when activated) with respect to the bearing block 74.

In an advantageous embodiment, a retaining means 191 shown in FIG. 37 is provided instead of the retaining means 111 fixing the stop 79, by means of which the transmission member 85, in particular the piston rod 85 or a corresponding extension piece, can be clamped. The holding means 191 may be integrated in the actuator 84, or as shown between actuator 84 and stop 79 may be arranged in such a way that the transmission member 85 is either fixable or freely movable in its direction of movement. The holding means 191 has, for example, two clamping jaws 192 with openings 193 or at least recesses for encompassing the transmission element 85, which are in operative connection with the transmission element 85 such that they are in a first operating state in which the longitudinal axis of the openings 193 parallel to the transmission element 85 run, the transmission member 85 release, and in a second operating state, in which the longitudinal axes of the openings 193 relative to the longitudinal axis of the transmission member 85 tilted, especially against each other spread, the latter with respect to a movement is clamped. Preferably, the holding means 191 is self-locking, so that when not actuated holding means 191, z. B. by the force of a spring 194, the second operating state is taken. The actuation of the jaws 192 via such inclined surfaces of an actuator 196, that the jaws 192 in a first position of the actuator 196 tilted (see above) and are not tilted in a second position. The holding means 191, in particular the actuator 196, can in principle be operated manually, for example via a corresponding actuating device, or advantageously by means of an actuator 197, in particular remotely operated, non-manually operable. The actuator 197 is formed in Fig. 37 as acted upon with pressure medium cylinder 197, in which the piston formed as an actuator 196 is movable. Upon application of the pressure P _s (FIG. 36 a), the clamping is released - here by corresponding alignment of the clamping jaws 192 or their openings 193. In the case of relaxation (FIG. 36 b), spreading or tilting takes place by means of the spring 194 the jaws 192 and thus a terminals.

A return of the stop 79 can either by the spring 86 shown in FIG. 9 or - as shown in phantom in FIG. 37 - active by the formation of the actuator 84 as a pressure medium actuated cylinder with double-acting piston, so with two pressure medium supply, one each on both sides of a piston 90.

In the illustrated embodiment, all four cylinders 06; 07 by actuators 82 mounted on / abstellbar, but only the stops 79 of the two forme cylinder 07 and one of the transfer cylinder 06 is not manually, ie via the pressure medium actuators actuators 84, in particular remotely operated, adjustable. The stop 79 of the other transfer cylinder 06 is, for example by means of a set as a screw adjustment means 84, adjustable and lockable. He must therefore, for example, have no holding means 111.

In an o. G. simpler variant, although all four cylinders 06; 07 linearly movably mounted by means of actuators 82, wherein only the two transfer cylinders 06 movable stops 79 (possibly with o. G. Actuators 84 and / or holding means 111).

In a further simplified embodiment, one of the two transfer cylinders 06, although adjustable in its position, but not in the sense of an on / Abstellbewegung operatively movable but mounted frame-fixed. The three other cylinders 06; 07 are then movably mounted in the sense of an on / off, wherein in a first variant, all these three cylinders 06, 07 and in the second variant, only the different from the specified transfer cylinder 06 transfer cylinder 06 has a movable stop 79 and possibly the holding means 111.

In a further development of the cylinder bearing, the bearing units 14 of the forme cylinder 07 and / or the transfer cylinder 06 as shown schematically in Fig. 25, on at least one end face itself in bearings 113, z. B. linear bearings 113, movably mounted in a direction of movement C, which is perpendicular to the cylinder axis of rotation and at least one component perpendicular to the direction of adjustment S has. Preferably, the direction of movement C is selected perpendicular to the direction of adjustment S and causes unilateral actuation an inclination (so-called. "Cooking") of the relevant cylinder 06; 07. The adjustment of the cylinder 06; 07 can via a manual or motorized actuating means 114, z. B. via a handwheel or preferably via a motor-operated adjusting spindle. Such additional storage of the bearing unit (s) 14 on the forme cylinder 07 allows an inclination of the same and a passport adjustment, and allows the transfer cylinder 06 whose inclination.

The actuator 82 provided in the above embodiment of the bearing units 14 is designed to provide a travel ΔS suitable for engagement or deactivation, and therefore preferably has a stroke corresponding at least to ΔS. The actuator 82 is for adjusting the Anstelldruckes to each other employed rollers or cylinders 06, 07 and / or to carry out the Druckan - / - provided off and designed accordingly. The travel ΔS (or stroke) is for example at least 1.5 mm, in particular at least 2 mm. In Fig. 38 is an advantageous embodiment of a -. This Aktorelement 97 comprises at least one, preferably two actuated with pressure medium as a piston 82 formed actuators 82 which in recesses 213 of a base body 215, which serve as pressurizable pressure medium 213, movable in the direction of adjustment S. are stored. The actuator element 97 also includes a supply line 214 for supplying the pressure chambers 213 with pressure medium of the pressure P. Preferably, the two pressure chambers 213 are supplied by a common supply line and thus oppressed or relieved in the same way. In Fig. 38, however, the upper piston 82 is exemplified for both pistons 82 in a retracted and the lower piston 82 exemplified for both pistons 82 in an extended position. For this reason, the supply line 214 was also only partially characterized as being pressurized.

The piston 82 is sealed against the pressure medium chamber 213 by a seal 82 surrounding the circumference of the piston 82, near the pressure chamber, and a sliding guide 217 close to the pressure chamber is guided. Advantageously, a second seal 218 and a second slide guide 219 may additionally be provided in a region of the piston 82 remote from the pressure chamber. In a particularly advantageous embodiment is instead of or in addition to the second seal 218 of the piston 82 to the outside in addition by a membrane 220, for. B. rubber, in particular a rolling diaphragm 220 sealed. This is on the one hand completely connected to the piston 82 and on the other hand on its outer peripheral line completely connected to the base body 215 and other fixed internals of the actuator element 97.

In an advantageous embodiment of the printing unit 01 are both parts of the printing unit 01, in particular wall sections 11; 12; 49 for the purpose of equipping or servicing the printing unit 01 relative to each other, in particular in a linear guide 15, as well as cylinder 06; 07 for adjusting the setting pressure and / or for performing the pressure on / off in linear bearings 70 within the corresponding wall section 11; 12 arranged linearly movable.

Although the drive designs described below are basically also independent of above-described divisibility and / or modularity and / or the cylinder arrangement on the inner walls of the side frame 11; 12 and / or the linear arrangement and / or the special linear bearing and / or the mentioned arrival, and adjustment of the cylinder 06; 07 of advantage. However, particular advantages arise especially in conjunction with one or more of the features mentioned.

In the following exemplary embodiments are presented for trained as a functional modules drive gear. In the drive solutions, functional groups of the printing unit 01 are sensibly combined and equipped with their own drive motors (see above), in particular servo, AC or asynchronous motors. A pressure cylinder gear with its own drive motor here includes, for example, the drive of a form cylinder-transfer cylinder pair. In addition, create a Farbwerksgetriebe with its own drive motor (for rotation and traversing movement) and, in the case of wet offset, a dampening with its own drive motor (for rotation and traversing movement) a high level of o. Modularity.

The prefabricated preferably as modules gear units can be used as subunits for the printing cylinder 06; 07 (FIGS. 26, 27) and / or for the inking units 08 (FIGS. 26, 27), which are embodied, for example, as a module, and in an advantageous embodiment already before being inserted into the printing unit 01 on the frame 147 (or frame construction 16). be pre-assembled the inking module. On the other hand, the modularity also allows the installation / replacement / replacement of the executed as a module Transmission, when the inking module is already inserted into the machine.

The concept of modularity for separate Druckwerkszylinder-, Farbwerks- and dampening unit drive allows both the divisibility of printing unit 01 at the pressure point 05 (see, for example, Fig. 3) and the divisibility between form cylinder 07 and inking unit 08 (see Fig. 24). The separate modules for printing cylinder 06; 07, inking unit 08 and possibly dampening unit 09 also allows simultaneous setup operation such as printing plate change and / or blanket washing while a Farbwerkwaschen and / or pre-inking takes place. The sequence programs can be different from one another in terms of duration, speed and functional sequence.

With less requirement for variability and / or modularity, larger functional groups may also be combined as modules (FIGS. 27, 28, 29).

The transmission or the gear train of the respective drive modules is designed in a preferred embodiment in each case as a single-encapsulated transmission and driven by at least one of the other functional modules mechanically independent drive motor. Thus, it is not necessary to consider an extensive oil space and / or drive connections when assembling a printing unit 01 from modules. The components are considered finished and completed.

By way of example, the conditions for the dry offset are shown on the left side of the figures, and for the wet offset on the right side. Of course, the two printing units 04 of a real double printing unit 03, however, are of the same type. In the frontal views was omitted for reasons of clarity on the roll pattern and only the drive trains are shown with motors. In plan view, the drive concept is exemplified by the example of an inking unit 08 with two rotationally driven friction cylinders 33 (see inking unit 08.2) and - in the case of wet offset - in contrast to FIGS. 11a) and 11b) - a dampening unit 09 with two rotatory driven friction cylinders 33 (indicated in FIG. 26 by dashed lines as optional).

The drive of the printing cylinder 06; 07 takes place at least in pairs, d. H. it is per cylinder pair 06, 07 from form and associated transfer cylinder 07; 06 at least one of further printing unit cylinders mechanically independent own drive motor 121 is provided. This can be z. B. in a variant, not shown, each be a separate, mechanically independent drive motor 121, or as shown below, done by paired drive via drive connections or trains.

In Fig. 26a) is in front view and in Fig. 26b) is a plan view of a gear or drive train 122, in particular as a drive or function module 122 executed, respectively for the pressure cylinder pairs 06, 07 shown. The cylinders 06; 07 each rotationally fixed on the drive shafts 78 connected drive wheels 123, in particular spur gears 123, whose head diameter is smaller than the outer diameter of the respective cylinder 06; 07 or bales 67; 68. These spur gears 123 are connected to each other via an even number of intermediate wheels 124; 126, here two, gears 124; 126 in drive connection. In an embodiment shown in Fig. 26a), one of the two gears 124; 126, in particular the Übertragungszylindernahe gear 126, effective as a pinion and driven by the motor shaft 127 of the drive motor 121. In principle, as in FIG. 27, the drive from the drive motor 121 can also take place via an additional pinion on one of the two drive wheels 123, in particular on that of the transfer cylinder 06.

The inking unit 08 each has its own, from the printing cylinder 06; 07 mechanically independent drive motor 128 for the rotary drive on. By this particular, the two distribution cylinders 33 of the inking unit 08.2 (in the case of an anilox roller 26, this or three friction cylinders 33 these three), z. B. driven by these rotatably connected drive wheels 129 and a drive pinion 131. In the case the wet offset (right) is essentially the same for the drive of the dampening unit 09 with a drive motor 132, a drive pinion 133 and one or more drive wheels 134 shown in phantom one or more distribution cylinders 42; 48. In Fig. 26b) is per distribution cylinder 33 of the inking unit 08 and each distribution cylinder 42; 48 of the dampening 09 a the axial traverse movement generating friction gear 136 and 137 arranged. This can in principle be driven by an additional drive motor, or as shown as a rotational movement in an axial movement transforming gear 136; 137 be formed. In a modification of the embodiment according to FIG. 26, the drive of the inking unit 08 can take place in accordance with FIG. 32, ie, only the friction cylinder 33.2, which is remote from the shape cylinder, rotatory, but if necessary both friction cylinders 33.1; 33.2 axially forcibly driven, and / or the drive of a three-roll dampening unit 09 as mentioned above for the development of Fig. 11a) to be rotationally driven purely by friction.

The drive of the extra driven inking unit 08 and, if provided the dampening unit 09, each preferably as a functional group, in particular as a drive or function module 138; 139 executed. In particular, these drive modules 138; 139 as a complete unit mountable and preferably carried out for each encapsulated (see Fig. 26b).

In Fig. 26 is an example of the other drive variants of the following figures, an advantageous embodiment of the bearing as bearing units 14 in the above-mentioned embodiment for the storage of the four cylinders 06; 07 indicated. The shafts 78 are, for example, by corresponding recesses / openings - possibly in view of the modularity and therefore different center distances as a slot - in the side frame 11; 12 led.

The corresponding or repeating parts were not each explicitly explicitly provided with reference numerals in FIGS. 26 to 29. In the advantageous embodiment shown in FIGS. 26 and 27, the axes of rotation of the four printing group cylinders 06; 07 of the double printing unit 03 arranged by way of example in the common plane E. However, the drive concept of Fig. 26 or 27 is also on non-linear arrangements of the cylinder 06; 07 as exemplified in Fig. 1, 28 and 29 with then corresponding non-linear arrangement of the drive wheels 123 to transmit. Likewise, the drive concept of Figure 28 and 29 to the linear arrangement of the cylinder 06; 07 to transfer.

In an embodiment according to FIG. 27, the printing group cylinders 06; 07 and the inking units 08 own drive as shown in Fig. 26. Although color and dampening drive are each designed as separate function modules, but the wet offset representing right printing unit 04 a dampening 09 without its own rotary drive motor. The rotary drive takes place here from the inking unit 08 forth via a mechanical drive connection 141, z. B. a belt drive 141, either directly on a with the respective distribution cylinder 42; 48 connected drive wheel, z. Example, a pulley, or, as shown, on a connected to the drive pinion 133 drive wheel 142, z. B. Pulley 142, which is the distribution cylinder 42; 48 and the distribution cylinder 42; 48. The drive is z. B. of a rotatably connected to the drive shaft of the drive motor 128 drive wheel 143, z. B. a pulley 143 ago. In a modification of the embodiment of FIG. 27, the drive of the inking unit 08 can be carried out as shown in FIG. 32, d. H. only the form cylinder remote friction cylinder 33.2 rotatory, and possibly both distribution cylinder 33.1; 33.2 driven axially forcibly, and driven from there to the dampening unit 09.

In an embodiment according to FIG. 28, the dampening unit 09 is designed as a functional module and, as in FIG. 26, has its own drive motor 132 as in FIG. 26. However, the inking unit 08 has none of the printing cylinders 06; 07 independent drive motor, but the rotary drive is carried by one of the cylinder 06; 07, in particular from the forme cylinder 07, forth via a mechanical drive connection 144, z. B. via at least one intermediate gear 144, in particular gear 144, between the spur gear 123 and drive wheel 129 of the distribution cylinder 33. The drive connection 144 may be performed in an advantageous variant as a belt drive. The drive of the printing couple cylinder pair 06, 07 with associated inking unit 08 is preferably as a drive train 146 or drive or function module 146, in particular at least the drive train of cylinder pair 06, 07 and inking unit 08 having space is z. B. formed encapsulated. In a modification of the embodiment according to FIG. 28, the drive of the inking unit 08 can take place in accordance with the principle set forth in FIG. 32, ie, only the friction cylinder 33.2 remote from the mold cylinder is rotatory via a drive connection from the forme cylinder 07, but possibly both distribution cylinders 33.1; 33.2 axially forcibly driven. The drive of a three-roll dampening unit 09 can be driven rotationally via the drive motor 132 or, as mentioned above for the development of FIG. 11 a), purely via friction.

In an embodiment according to FIG. 29, the dampening unit 09 is designed as a functional module and, however, as in FIG. 27, does not have its own drive motor. The inking unit 08 has, as in FIG. 28, an independent drive motor but, as in FIG. 28, rotates again by one of the cylinders 06; 07, in particular from the forme cylinder 07, forth via a drive connection 144, z. B. an intermediate gear 144 is driven. The drive of the dampening unit 09 is effected as in FIG. 27 via a belt drive 141. The drive of the printing couple cylinder pair with associated inking unit 08 is preferably again embodied as a function module 146, in particular encapsulated. In a modification to FIG. 29, the drive of the inking unit 08 may take place in accordance with the principle set forth in FIG. 32, ie, only the friction cylinder 33.2 remote from the mold cylinder is rotated via a drive connection from the forme cylinder 07, but possibly both distribution cylinders 33.1; 33.2 axially forcibly driven. The drive of a three-roller dampening unit 09 can be driven via the drive connection 141 or, as mentioned above for the development of FIG. 11 a), purely rotationally driven by friction. In further, not shown fifth variants can be executed together as a functional module with a common drive motor in wet offset pressure cylinder gear and dampening gearbox, the function module 138 z. B. itself as shown in FIG. 26 is maintained and has a drive motor 128. In a modification, although the inking unit 08 is designed as a functional module 138, it is driven without a separate motor via a belt drive from the impression cylinder gearbox.

In a modification to Fig. 27, the drive to the running as a functional module 139 dampening unit drive instead of the inking unit 08 and the drive train 122 of the printing cylinder 06; 07 via a belt drive.

As can be seen in FIGS. 26 to 29, the drive modules 122 with the two printing unit cylinders 06; 07 in each case via at least one torsionally rigid coupling 148, in particular at least one angle-compensating coupling 148 coupled. Preferably, two such couplings 148 are provided in series with an intermediate piece (or a total of a double-jointed component) which then represents a total of an offset compensating coupling 151. This is despite mobility (on / off) of the cylinder 06; 07 a frame-fixed arrangement of the drive modules 122 and drive motors 121 possible. During assembly, only the coupling (s) 148 having shafts 78 must be flanged to the self-completed function modules 122. From the - in particular outwardly sealed or encapsulated - function module 122 protrude advantageous in the figures indicated stub shafts or flanges, which upon assembly of the printing unit 01 only with the clutch 148; 151 having the shaft piece and this are rotatably connected to the shaft 78. Particularly advantageously, the clutch 148 is designed in each case as a multi-disc clutch 148 or all-metal clutch and has at least one form-locking, but offset in the circumferential direction of the blades offset with two flanges disc set.

The coupling 151 between the functional module 122 and the forme cylinder 07 is preferably designed to enable side register control in such a way that it also receives an axial relative movement between the forme cylinder 07 and the functional module 122. This can also be done by o.g. Multi-plate clutch 148 take place, which allows an axial length change by deformation in the region of the slats. An unillustrated axial drive can be provided on the same or the other frame side as the rotary drive.

The driven rollers 33, in particular friction cylinder 33, of the inking unit 09 are preferably coupled to the functional module 138 via at least one coupling 149, in particular angle compensating compensating coupling 149. Since i.d.R. no turning off / on of these rollers 133 takes place, it may be left in such a clutch 149. In a simple embodiment, the coupling 149 is also designed only as a rigid flange connection. The same applies to the drive on possibly as a function module 139.

In Fig. 26 to 29, the friction gear 136; 137 outside of an encapsulated, the rotary drive trains accommodating space, in particular lubricant space, be arranged.

The drive modules 122; 138; 139; 146 running drive trains 122; 138; 139; 146 are completely separate by themselves from side frames 11; 12 different - housing 152; 153; 154 completed units executed. You have, for example, an input to which z. B. a drive motor or a drive shaft can be coupled, and one or more outputs which rotatably with the cylinder 06; 07 or the roller (screen or friction roller 26, 33, 42, 48) is connectable.

Instead of the above-described coupled pressure cylinder drives, the pressure cylinder 06; 07 in a likewise advantageous embodiment also individually be driven by a drive motor 121 (FIG. 30). Preferably, in a "drive train" between the drive motor and cylinder 06; 07, a transmission 150, in particular a reduction gear 150, such. B. a planetary gear provided. This can be structurally already pre-assembled as an auxiliary unit with the motor 121 as a structural unit as an auxiliary transmission. However, it can also be provided as a drive or functional module, a module-like transmission, at the input of the drive motor and at the output of the respective cylinder - in particular via an angle and / or offset compensating coupling 148 or 151 - can be coupled.

In the embodiments according to FIGS. 26 to 30, the drive motors 121 with their drive modules 122 or transmissions 150 are arranged fixed to the frame on the side frames 12. The necessary offset when turning on / off the Nippstellen is made possible by the clutches 148 here. In an advantageous embodiment, not shown here are in a further development of the embodiment of Figure 30, the individual drive motors 121 (in particular with auxiliary gear 150) per unit cylinder 06; 07 not on the side frame 12, but directly connected to the movable bearing member 74 rigid, z. B. screwed, and are moved during the adjusting movement. To support the drive motors 121 may be provided on the side frame 12, a holder with guide on which the drive motor 121 are supported and upon movement of the respective cylinder 06; 07 in the direction S can be moved.

Fig. 31 to 35 shows a -. B. regarding Farbtransport and wear advantageous - embodiment of the inking unit 08 and the inking unit, which by itself, but especially in conjunction with one or more features of o. G. Printing units 01 Advantages.

The inking 08, z. B. referred to as einzughiges roller inking unit 08 or as a "long inking unit", has a plurality of the above-mentioned rollers 28; 33; 34; 36; 37 on. It comprises according to FIG. 31 (at least) two, the color on the printing form The application rollers 28 which apply the ink to the forme cylinder 07 and which transfer the ink via a printing forme cylinder or form cylinder near the oscillating friction roller 33.1 or friction cylinder 33.2 (eg with a hard surface), a color or transfer roller 34 (eg with a soft surface), a second form cylinder remote changeable friction roller 33.2 or Reibzylinder 33.2, another color or transfer roller 34 (eg., With a soft surface), a film roll 37 and a ductor or fountain roller 36 from an ink fountain 38 receives. Dipping and film roller 36; 37 (characterizing a film inking unit) can advantageously also be replaced by another ink feed or metering system (eg pumping system in the pumping inking unit, or lifting system in the lifting inking unit).

The soft surfaces of the application and / or transfer rollers 28; 34 (in short: soft rollers 28, 34) are yielding in the radial direction, z. Formed with a rubber layer, which is expressed in Fig. 31 by the concentric circles.

Will now the rollers 28; 33; 34; 37 of the inking 08 set against each other, so dive depending on the contact pressure and / or travel the hard surfaces of the distribution cylinder 33.1; 33.2 in the soft surfaces of the respective cooperating soft rolls 28; 34 more or less far. As a result, depending on the indentation depth, the circumferential proportions of rollers rolling against each other, acting together, change; 33; 34; 37th

If, for example, one of a plurality of co-acting rollers has a positive rotary drive by specifying a rotational speed (eg via a drive motor or a corresponding mechanical drive connection to another driven component), an adjacent one only rotates by friction from the first-mentioned roller driven soft roller depending on Eindrückiefe with different speed. In the event that this soft roller but additionally driven by a separate drive motor or in addition via friction in a second nip from another speed-determined roller ago, this can in the first case, a difference between the engine speed and the speed caused by friction, and in the second case, a difference between the two speeds caused by friction. Slippage occurs at the nip points and / or the drive motor (s) are unnecessarily heavily loaded.

In the area close to the cylinder surface of the inking unit 08, in particular in the region of the ink application by the rollers 28 to the printing forme, a slip-free rolling ("true rolling") and coloring is achieved by the solution described below:

The form cylinder near the friction cylinder 33.1 is rotational only by friction with adjacent rollers 28; 34 driven and has its rotary drive neither an additional mechanical drive connection for driving the printing cylinder 06; 07 or another rotary forcibly driven inking roller nor its own drive motor. In this way, the first distribution cylinder 33.1 is driven rotationally predominantly via the application rollers driven by friction with the forme cylinder 07 in this example (optionally also one or three) and essentially has the peripheral speed of the forme cylinder 07, irrespective of the indentations in the intermediate nipples on. The form cylinder remote friction cylinder 33.2 has, as indicated in Fig. 31, a rotationally driving drive motor 128, which, however, in addition to the through the rollers 33.2; 34; 33.1 formed friction gear has no mechanical coupling to the first distribution cylinder 33.1. For more than two friction cylinders 33.1; 33.2, z. B. three, the two form cylinder distant rotationally forcibly driven, or it can only be the middle or the form cylinder remote friction cylinder 33.2 rotationally driven.

Preferably, both distribution cylinders 33.1; 33.2 a by in Fig. 31 by respective double arrows symbolized traversing or friction gear 136. In a mechanically less elaborate embodiment, the cylinder near cylinder near friction cylinder 33.1 has its own, only its rotational movement in a traversing motion transforming traversing 136. This can be advantageously designed as a cam gear, wherein z. B. a frame-fixed axial stop cooperates with a roller-fixed curved circumferential groove or a roller-fixed axial stop in a frame-fixed circumferential groove of a cam. Basically, this rotation in a iridescent Axialhub transforming gear 136 another suitable gear 136, z. B. by an eccentric exhibiting worm or crank gear, be executed.

As symbolized in FIG. 31 by a dashed line connecting the double arrows, the traversing gear 136 of the first rubbing cylinder 33. 1 is mechanically coupled in an advantageous manner via a gear 161 to the traversing gear 136 of the second rubbing cylinder 33. Advantageously, the two coupled traversing gears 136 represent a common traversing drive 162 (traversing gear 162) and are forcibly driven for their traversing movement by a drive motor. Preferably, the forced drive of the traversing gear 162 is effected by the drive motor 128 rotationally driving the second distribution cylinder 33.2 (FIG. 32).

In Fig. 32 and 33 is an advantageous embodiment for the drive of the distribution cylinder 33.1; 33.2, wherein only the second distribution cylinder 33.2 is forcibly driven in rotation, but both distribution cylinders 33.1, 33.2 are axially positively driven via the common traversing drive 162. The printing cylinder 06; 07 can either be as shown in Fig. 26 in pairs by drive motors 121 per cylinder pair, or advantageously individually by a respective drive motor 121 as shown in Fig. 30, executed.

For this purpose, the drive motor 128 drives via a coupling 163 via a shaft 164 to a drive pinion 166, which in turn rotatably connected to the second distribution cylinder 33.2 connected spur gear 167 cooperates. The connection can z. B. via a spur gear 167 supporting shaft portion 168 carried on a pin 169 of the second Reibzylinders 33.2. A corresponding axle section 168 of the first friction cylinder 33.1 has no such spur gear 167 or no drive connection to the drive motor 128. The drive connection between the drive pinion 166 and spur gear 167 of the second Reibzylinders 33.2 are preferably straight teeth and formed with a sufficient for each position of traversing movement coverage in the teeth engagement. The two distribution cylinders 33.1; 33.2 are in a formed on the side frame 147 or frame 16 frame 147 in bearings 172, z. B. radial bearings 172 stored, which also allow axial movement. A rotary drive connection between the drive motor 128 and the first distribution cylinder 33.1 does not exist here. Drive pinion 166 and disposed on the axle 168 spur gear 167 together represent a transmission, in particular reduction gear, which is a self-contained and / or preassembled unit with its own housing 153. The assembly is the output side of the pin 169 coupled.

The traversing drive 162 is also by the drive motor 128, z. B. via a worm drive 173, 174, driven. In this case, a screw 173 arranged from the shaft 164 or a section of the shaft 164 designed as a screw 173 is rubbed onto a worm wheel 174, which is rotationally fixed with a rotation axis of the friction cylinder 33.1 perpendicular to the axis of rotation. 33.2 extending shaft 176 is connected. In each case front side of the shaft 176, a driver 177 is arranged eccentrically to the axis of rotation, which in turn z. B. via a crank mechanism, for example via a rotatably mounted on the driver 177 lever 178 and a hinge 179, in the axial direction of the distribution cylinder 33.1; 33.2 pressure and zugsteif with the pin 169 of the distribution cylinder 33.1; 33.2 is connected. In Fig. 31, the friction gear 136 of the form cylinder distant friction cylinder 33.2 is only indicated by dashed lines, since it is hidden in this view by the spur gear 167. A rotation of the shaft 176 causes a rotation of the driver 177, which in turn via the crank drive an axial stroke the distribution cylinder 33.1; 33.2 causes. The output to the traverse drive 162 can also take place at another point of the rotary drive train between the drive motor 128 and the friction cylinder 33.2 or even on the other side of the machine on the other end face of the Reibzylinders 33.2 pin 169 to a corresponding traversing gear 162. Also may optionally be provided by a worm gear 173, 174 different gear for coupling the axial drive.

As shown in FIG. 32, the traversing drive 162 or the traversing gear 162 as a whole is designed as a structural unit with its own housing 181, which may be additionally encapsulated. The traversing gear 162 may be lubricated in the enclosed space either with oil, but preferably with a grease. The traverse gear 162 is supported in the illustrated embodiment by a bracket 182 connected to the side frame 147. The drive motor 128 is in this case detachably connected to the housing 181 of the traversing gear 162.

Fig. 34 shows an advantageous embodiment of a torsionally rigid connection between the axle portion 168 and the respective pin 169. This is about a rotation about a frictional engagement, which is made by clamping a tapered portion of the pin 169 by the slotted axle portion 168 comprising this becomes. The position of a clamping screw 183 is dimensioned such that it - at least partially immersed in a circumferential groove of the pin 169 - viewed transversely to the axis of rotation of the pin 169. It thus represents an interlocking securing of the connection with respect to an axial direction.

A further advantageous development is explained with reference to FIG. 35, wherein the distribution cylinders 33. 1; 33.2 including rotary and axial drive in the manner of a total pre-assembled and / or movable module on its own, of a the printing cylinder 06; 07 carrying side frames 11; 12 structurally different side frames 147 (16) are arranged. A second, the friction cylinder 33.1; 33.2 on her other end side supporting frame side is not shown here. These the friction cylinder 33.1; 33.2 and their drive supporting side frames 147 (16) are then depending on the size and geometric arrangement of the printing cylinder 06; 07 on the side frame 11; 12 positionable. Figs. 35a) and 35b) show a relative position of the side frames 147 (16) and 11; 12 to each other when using a larger (a) and a smaller (b) forme cylinder 07. A marked by double arrow in Figure 35 distance between the side frame 11; 12 and the inking unit drive, here the traversing gear 162, is then different depending on the position of running in the manner of a module inking unit 08. This can print units 01 with printing cylinders 06; 07 different circumferential formats can be operated in a simple manner by the same inking unit 08.

The prefabricated preferably as a module transmission unit (from axial and / or traverse 162) may be completely pre-assembled as a subunit for example designed as a module inking 08 and pre-assembled in an advantageous embodiment before use in the printing unit 01 on the side frame 147 (16) of the inking module be. On the other hand, the modularity also allows the installation / replacement / replacement of the module designed as a transmission when the inking unit module is already inserted into the machine.

As a result of the fact that the friction cylinder 33.1 close to the positive cylinder cylinder does not have a positive drive in rotation, the rollers 28 (34) roll against each other largely without slippage, at least in the area of the inking unit near the impression cylinder.

In principle, the drive motor 128 which rotatably drives the second distribution cylinder 33.2 can be embodied as an electric motor that is controllable with respect to its power and / or its torque and / or also with respect to its speed. In the latter case, it can then - if the drive motor 128 is also speed-controlled in pressure-on /-controlled - in the form of cylinder remote area of the inking unit 08 yet og problems in terms of different effective Roll circumferences come.

In view of the above-described problem of competing with the friction gear speed specification, however, the drive motor 128 is advantageously designed such that it at least during the printing operation with respect. Its power and / or its torque is controlled or regulated. This can basically be done by means of a drive motor 128 designed as a synchronous motor 128 or as an asynchronous motor 128:

In a first embodiment, which is simplest in terms of expenditure, the drive motor 128 is designed as an asynchronous motor 128, which has only one frequency (eg in pressure-down of the inking unit 08) in an associated drive control 186 and / or an electric drive power or a torque (in print-on of the inking unit 08) is specified. In print-off of the inking unit 08, d. H. the applicator rollers 28 are out of rolling contact with the forme cylinder 07, can be brought about the predetermined frequency and / or drive power the inking unit 08 via the second distribution cylinder 33.2 to a suitable for the pressure-On-sites peripheral speed at which the peripheral speeds of forme cylinder 07th and applicator rollers 28 only by less than 10%, in particular less than 5%, from each other (this limit is also advantageous as a condition for the pressure-on-sites of the embodiments mentioned below). A frequency or power specification suitable for this purpose can be empirically and / or computationally determined beforehand and kept either in the drive control itself, a machine control or a control computer. The default value is preferably changeable by the operator, wherein the default value is preferably changeable by the operating personnel (advantageously also applies to the default values mentioned below).

In print-on, ie the applicator rollers 28 are employed in rolling contact with the forme cylinder 07 and all inking rollers to each other, the rollers 28; 33; 34; 33; 34; 37 to a part of the forme cylinder 07 via the now produced friction gear between the rollers 28; 33; 34; 33; 34; 37 rotationally driven. so that the drive motor 128 only has to bring in the increasing power dissipation in the friction gears with increasing distance from the forme cylinder 07. That is, the drive motor 128 can be operated with a small drive torque, which merely contributes to keeping the rear portion of the inking unit 08 at the peripheral speed substantially determined by the frictional contact. This drive power can be left constant in a first variant for all production speeds (or rotational speeds of the forme cylinder 07) and either correspond to that specification for starting in pressure-Ab or represent its own constant value for the production. In a second variant, different specifications with regard to the frequency and / or drive power can be predetermined and stored for different production speeds (and possibly also for starting in pressure-off). Depending on the production speed (production speed), the specification for the drive motor 128 can then vary.

In a second embodiment, the drive in addition to the drive control 186 and the induction motor 128 of the first embodiment, a speed feedback, so that the drive motor 128 in the phase of the inking unit operation in pressure-Ab with the speed of the associated plate cylinder 07 and the printing cylinder 06; 07 is essentially synchronized. For this purpose, the actual speed detecting sensor 187, z. As a rotary encoder 187, on a non-rotatably connected to the distribution cylinder 33.2 rotating component, eg. Example, a rotor of the drive motor 128, the shaft 164, the shaft 164, etc. may be arranged. In FIG. 32, a rotary encoder 187 having a co-rotating initiator and stationary sensor 187 is shown by way of example on the coupling 163, the signal of which is fed to the drive control 186 for further processing via a signal connection shown in dashed lines. By the speed feedback, the comparison with a speed representing the engine speed M and a corresponding adjustment of the power or frequency specification Slip is avoidable at the moment of pressure on-set or at least minimized to a few percent. In the print-on operation, the drive motor 128 is then preferably no longer strictly with respect to the described speed feedback but essentially operated according to the frequency or power specification described above.

A third embodiment has a synchronous motor 128 instead of the asynchronous motor 128 of the second embodiment. A speed feedback and a related synchronization and control in the pressure-off phase is carried out according to the second embodiment, for. B. again in the drive control 186th

In a fourth embodiment, a drive motor 128, in particular a synchronous motor 128, is provided, which is optionally speed-controlled in a first mode (for inking unit 08 in print-Ab) and in a second mode with respect to a torque (for inking unit 08 in print-on). is controllable. Drive control 186 and drive motor 128 preferably have an internal control loop for speed control, which, similarly to the second embodiment, comprises a return from an external rotary encoder 187 or an internal sensor system. When synchronous motors 128 are used, a plurality of these synchronous motors 128 of a printing unit 01 can be assigned a common frequency converter or converter.

A respect to versatility advantageous, but more complex development of the fourth embodiment is the formation of the drive motor 18 as a selectively position and torque controllable servo motor 128, ie a three-phase synchronous motor with a device that allows the current rotational position or the angle of rotation with respect to a To determine the initial position of the rotor. The feedback of the rotational position can via a rotary encoder, z. As a potentiometer, a resolver, an incremental encoder or an absolute encoder done. In this embodiment, each drive motor 128 is assigned its own frequency converter or converter.

In the case of an at least speed-synchronizable, in particular speed-controllable drive motor 128 designed in the manner of the second, third or especially fourth embodiment, the drive control 186 is advantageously in signal connection with a so-called virtual master shaft in which an electronically generated master axis position Φ circulates. The circumferential Leitachsposition Φ is the synchronization, with respect. Correct angular position and its temporal change

(Angular velocity Φ̇) mechanically independent drive motors of units which are assigned to a same track, in particular drive motors 121 of individual printing cylinders 06; 07 or groups of printing cylinders (pairs) and / or the drive of a folder. In the mode of operation in which the inking unit 08 is to be driven synchronized with respect to the rotational speed of the forme cylinder 07, a signal connection to the virtual master axis can thus provide the drive control 186 with the information about the speed or speed of the machine.

Preferably, when the friction cylinder 33.2 is driven via the drive motor 128, the inking mechanism 08 is in operation, but is controlled and regulated in terms of a rotational speed and is driven when the inking unit 08 is running (but in parked applicator rollers 28) running machine, as soon as a pressure on the inking unit 08 (ie the applicator rollers 28) is done, the speed control or control is deliberately abandoned. D. h., It is no longer held at a speed, but the drive motor 128 is in the course of a torque, z. B. over a predetermined electrical power, and / or in terms of a controller on the drive motor 128, in particular asynchronous motor 128, adjustable torque operated. The torque to be set or the power to be set, for example, is selected to be smaller than a limit torque which would lead to a first rotation (under slip) of the driven friction cylinder 33.2 when the cooperating rollers 34 are set but fixed with respect to rotation.

The load characteristic of a drive motor 128 embodied as an asynchronous motor 128 counteracts the behavior intended for the purpose here in such a way that, as the load increases, the frequency is reduced while the drive torque increases. Goes in the friction gear between forme cylinder 07 and second friction cylinder 33.2, for example, already a lot of form cylinder 07 derived drive energy and thus peripheral speed lost, so that the load of the drive motor 128 grows, so the increased torque is provided at a reduced frequency. Conversely, little torque is transmitted by the drive motor 128 - it runs virtually empty - when sufficient energy is transmitted through the friction gear to the distribution cylinder 33.2.

The design of the cylinder bearings as bearing units 14 and / or the cylinder 06; 07 as a cylinder unit 17 and / or the inking units 08 in the form of modules and / or drives in the manner of drive modules and / or the separability of the printing unit 01 allows - depending on equipment at different depths - a simplified on-site assembly and thus extremely short installation - and commissioning times at the customer.

For example, the side frames 11; 12 or wall sections 11; 12; 47 set up and aligned and the cylinder units 17 and / or inking units 08 and / or dampening 09 in the manner of modules outside the side frames 11; 12 pre-assembled.

The cylinders 06; 07 are still outside of the racks 11; 12 equipped with their storage units 14 and then completely as a cylinder units 17 between the side frames 11; 12 introduced and fixed. From the outside of the side frame 11; Depending on the drive design, the drive unit in the manner of a drive module (eg, gear 150 or drive train 122 with the corresponding drive motor 121, if necessary via the shaft) is then produced by corresponding frame recesses 78) with the pin 63; 64 connected.

If the printing unit 01 is designed to be divisible in the area of the printing areas 05, the cylinder units 17 are preferably opened when the printing unit 01 is open, from between the two partial printing units 01.1; 01.2 lying room introduced and only after introduction this again closed.

If the printing unit 01 on both sides of the double printing unit 03 to the inking units 08 divided out executed (Fig. 24), the cylinder units 17 are preferably at between printing cylinders 06; 07 and the inking units 08 receiving wall sections 47 open pressure unit 01 introduced from the space formed therefrom ago and closed only after introduction of these.

For the inking units 08, the own inking frames 16 and 147 are still outside the side frames 11; 12 equipped with the corresponding rollers (from 26 to 39) and the corresponding drive module 138 (possibly already including drive motor 128) and introduced as a whole in the printing unit 01 and fixed there.

Even with the dampening 09 can dampened own racks still outside the side frames 11; 12 with the corresponding rollers (from 41, 42, 43, 47, 48) and, if required in the desired embodiment, the corresponding drive module 138 (optionally with or without its own drive motor 132) and introduced as a whole into the printing unit 01 and be fixed there.

FIGS. 39 a) to 39 d) schematically show four embodiments for a printing machine, which has a plurality of printing units 01 described above-divisible or possibly not divisible. The printing presses have roll changers 236 with feed mechanisms (237) not explicitly shown, a superstructure 238 with at least one longitudinal cutting device, a turning end and a longitudinal register device for longitudinally cut partial webs, optionally a dryer 239 shown by dashed line in FIG. 39d), a funnel structure 241 with one, two or even three side by side arranged in one plane formers and a folding apparatus 242. With this three printing units 01 having printing machine are in the case of an embodiment with double-wide, ie four printed pages (especially newspaper pages) wide and double-sized printing cylinders 06; 07 with three tracks 02 altogether 48 pages each four-color printable.

Fig. 39 a) shows the printing machine in Patterre line-up, d. H. the printing units 01 and the roll changer 236 are set on a same level. In Fig. 39b), a printing machine is shown, wherein two each four double printing units 03 having printing units 01 are arranged on two different levels. In particular, the upper printing unit 01 is arranged with its entire height above the lower printing unit 01. With this three printing units 01 having printing machine are in the case of a design with double-wide, d. H. four printed pages (especially newspaper pages) wide and double-sized printing cylinders 06; 07 with three tracks 02 altogether 48 pages each four-color printable.

Fig. 39 c) shows a printing press on three levels, wherein in a lowermost level, the roll changer 236, and on the two levels above two each four double printing units 03 having printing units 01 are arranged one above the other. By way of example, the printing press has two such pairs of two printing units 01 arranged one above the other. With this four printing units 01 having printing machine are in the case of a design with double-wide, d. H. four printed pages (especially newspaper pages) wide and double-sized printing cylinders 06; 07 with four lanes 02 a total of 64 pages each can be printed in four colors.

In Fig. 39d), a printing machine is shown on two levels, wherein in the lower

Level, the roll changer 236 and in the plane above the four double printing units 03 having printing units 01 are arranged. With this three printing units 01 having printing machine are in the case of a design with double-wide, d. H. four printed pages (especially newspaper pages) wide and double-sized printing cylinders 06; 07 with three tracks 02 altogether 48 pages each four-color printable.

For all training of a printing press with one or more of the o. G. Features for divisibility and / or modularity and / or the cylinder arrangement on the inner walls of the side frame 11; 12 and / or the linear arrangement and / or the special linear bearing and / or the mentioned arrival, Ab- and adjustment of the cylinder 06; 07 and / or the drive modules 122; 138; 139; 146, a folder 242 is preferably provided with its own drive motor and / or with variable format or section length (i.e., a variable format folder 242) mechanically independently of the printing units 01.

The folder 242 shown schematically in Fig. 40 has z. As a knife cylinder 243, a transport cylinder 244 and a jaw cylinder 246. At least the transport cylinder 244 designed as a folding blade cylinder 244 has a variable-format configuration, ie a distance ΔU in the circumferential direction between holding means 247 and respectively subsequent folding blades 248 on the circumference of the transporting cylinder 244 is variable. For this purpose, the holding means 247, z. B. as Punkturleisten or gripper, on the one hand and the folding blade 248 on the other hand be arranged on two different coaxial drums, which can be rotated in the circumferential direction to each other. If the distance .DELTA.U between holding means 247 and downstream folding blade 248 is reduced, then a product section 249 transversely cut off from a strand 251 by the knife cylinder 243 is folded transversely on extension of the folding blade 248 to a shorter section length and vice versa. The strand 251 may consist of one or more longitudinally folded or unfolded webs 02 or partial webs exist.

Although the drive control described below is basically also independent of the above-described divisibility and / or modularity and / or the cylinder arrangement on the inner walls of the side frame 11; 12 and / or the linear arrangement and / or the special linear bearing and / or the mentioned arrival, Ab- and adjustment of the cylinder 06; 07 and / or the drive modules advantageous. However, particular advantages arise straight in conjunction with one or more of the features mentioned, in particular in conjunction with mechanically independently driven units - such. B. mechanically independently driven folder 219 and / or printing unit 01 and / or retraction 214 and / or cylinders 06; 07 or cylinder groups and / or guide elements of a superstructure 216).

41 shows an example of the drive of a printing press with a plurality of printing units 01, which are here by way of example two, in the form of printing towers 01, which each have a plurality of printing units 03, here double printing units 03. The printing units 03 of a printing tower 01 together with their drive controllers 221, briefly drives 221 and the drive motors 121; 128 a group 223, z. B. drive motor 223, in particular a pressure point group 223, which is connected via a subordinate drive control 224 of this group 223 with a signal of a respective Leitachsposition Φ a virtual leading axis leading first signal line 226. However, the slave drive controller 224 may also manage subgroups of printing units 01 or other divisions. With this signal line 226 are also further, own subordinate drive control 224 having units, for. B. one or more guide elements of a superstructure 238 and / or funnel structure 241 and / or one or more folders 242 connected. The signal line 226 is here advantageously designed as a first network 226 in ring topology, in particular as a Sercos ring, which transmits the master axis position Φ through a superordinate network connected to the network 226 Drive control 227 receives. This generates the circulating Leitachsposition Φ on the basis of specifications relating to a given production speed, which they from a computing and / or data processing unit 228, z. B. a section computer receives. The computing and / or data processing unit 228, in turn, receives the specification of the production speed from a control station 229 or control center computer 229 connected to it.

In order to ensure register-based printing and / or slitting the mechanically independently driven units, eg. B. depending on a web guide, are in the correct angular position to each other. For this purpose, 221 offset values ΔΦ _i are maintained for the individual drives, which define the correct angular position for producing relative to the common guide shaft and / or relative to one of the units.

The relevant for the individual drives 221 offset values ΔΦ _i for the production in question by the computing and data processing unit 228 via a second, different from the first signal line 226 signal line 231, in particular a second network 231, the respective drive 221 associated subordinate drive controls 224th fed and stored in an advantageous embodiment there and processed with the Leitachsposition Φ to corrected Leitachspositionen Φ _i '.

The transmission of the offset values AΦ _i to the subordinate drive controllers 224 takes place for example. Example, either via corresponding signal lines from the second network 231 directly to the drive controller 224 (not shown), or advantageously via a control system 232, which is assigned to the respective group 18 and the own subordinate drive control 224 having unit. For this purpose, the control system 232 is connected to the second network 231 (or to the computing and data processing unit 227). The control system 232 controls and / or controls, for example, those of the drive motors 121; 128 different actuators and drives the printing units 03 and folders 242, z. As ink supply, positioning movements of rollers and / or cylinders, dampening, positions, etc. The control system 232 has one or more (in particular programmable) control units 233 on. This control unit 233 is connected to the subordinate drive control 224 via a signal line 234. In the case of several control units 233, these are connected by the signal line 234, z. B. a bus system 234, also interconnected.

Via the first network 226, the drives 221 thus receive the absolute and dynamic information for circulating a common control axis position Φ, and via a second signal path, in particular via at least one second network 231, the information required for register-correct processing, in particular offset values ΔΦ _i , for the register-oriented relative position of the mechanically independent drives 221 or units transmitted.

The lying for the double printing unit 03 lying in the above-mentioned individual or several communicating advantageous features (storage unit 14, level E, linear travel S, modularity, drive trains) are also on I-pressure units, ie substantially rotated by 90 ° double printing 03, apply , Except for the feature of the planar printing unit 03, the features of the storage unit 14 and / or the linear travel S and / or modularity and or the drive trains are also applicable to nine- or ten-cylinder satellite printing units individually or in combinations.
