The automated machine has a directional station, a transfer station and a cable adjustment station for pulling the cable into position. The directional station has a a pair of roller sets that form the feed unit.

Description

In line processing machines with insulation jacketed electrical lines automatically processed by they e.g. cut to length, stripped, crimped and housed in electrical Connectors are used. The electrical lines are of considerable length before being processed stored on spools or in barrels. You will be using automatic working feeders from the storage facility deducted and the first processing station of the line processing machine fed.

Line processing machines are for more economical use have been developed that are not just a line or a line type, e.g. just a line of certain thickness or Process pattern or color or the like, but several can process different lines. Accordingly are also automatic line feeders with line changer for the line processing machines have been developed from several grouped or compiled Line storage Pull out lines and several Can store cables. With such a Line feeder is one line of which first processing station of a line processing machine, usually fed to a stripping and deflection station. Should e.g. after a stored line has been used up, the same, Management already provided from another supply processed or a line change to another provided cable type with e.g. other thickness and / or Strand and / or color or the like, the line change device the line feeder in operation set and the lines changed.

Devices of the type dealt with above are e.g. in the WO 89/03 601 and EP 0 598 276 B1. Not described in these publications is that the feeders usually also with so-called line straightening devices are equipped with straighteners from the stocks straighten the stripped cables, i.e. curvatures, Push out bends, kinks or the like so that the Lines no longer have any deviations perpendicular to the longitudinal axis. This straightening is necessary to guarantee a trouble-free further transport and trouble-free processing a line in a line processing machine.

A line feed device on the market with Line changer that that described in EP 0 598 276 B1 corresponds, works with one each between the line storage device and arranged the line transport means Straightening device per line, so that in the known feeder a corresponding space is used for this or the feed device must be oversized accordingly. Each straightening station consists of two in the direction of transport Line one behind the other and grouped arranged roller sets, each set of rolls having diagonally opposite throat rolls has, the waves perpendicular to the transport direction of the Line are aligned. Form the roles of a role set a conduit. The waves of the rolls of a set of rolls are perpendicular to the waves of the other set of rollers. The Rollers are also adjustable in the direction of the line.

The straightening devices have to be time-consuming individually by hand be adjusted or discontinued if, after using up a Stocking introduced a new line and / or on one another line type must be changed. The adjustment or Hiring or conversion requires experience and becomes empirical executed, that is, it is carried out with a lead of the line the straightening mechanism is adjusted until the line is sufficient is directed straight.

The object of the invention is a simple, quick, reliable and automatically working straightening device create that usable for all lines to be processed is.

This object is solved by the features of claim 1. Advantageous developments of the invention are described in these Claims dependent dependent claims marked.

In Figures 1 to 3 is the overall structure of a line feed device 4 shown with line changer. It can two such identical line feed devices according to the invention with cable changer - viewed from above - V-shaped and to each other in mirror image to one between the two feeders lying vertical mirror plane 21 (Fig. 4, 5) be put together.

The two line feed devices are expedient assembled with a line changer on a horizontal base plate 1, which is preferably trapezoidal, the a line feed device with line changer in the area 2 one side edge and the other in area 3 of the other Side edge of the base plate 1 is arranged. Is shown in 1 to 3 of these only the line feed device constructed in area 2 4th

The line feeder with line changer 4, which in following, for the sake of simplicity, only with feed device 4 is referred to, points in the line transport direction 5 from behind (line inlet side) lined up to the front (line outlet side) a line straightening station 6, a line transport station 7 and a line withdrawal station 8.

Four electrical examples are shown in FIGS. 1 to 3 Lines 9, leading line paths 9a, one above the other vertically and horizontally parallel at a distance from each other through the Feeder 4 are performed. Of course you can more line paths 9a may be provided. The feeder shown 4 is for twelve superimposed line paths designed. In combination with the other not shown Feeder can thus twenty-four lines 9 are kept ready in line paths 9a.

All lines 9 are from storage facilities, not shown deducted and on the straightening station side or in the transport direction inserted into the feed device 4 from behind and into Transport direction 5 horizontally through the entire feed device 4 performed. At the retraction end of the feeder 4 are each from a mouth of a nozzle 10 Lines 9 can be removed, the nozzles 10 also at a distance the lines 9 are arranged vertically one above the other. The nozzles 10 downstream of the transport direction 5 is the first processing station a line processing machine provided (not shown).

In the area of the longitudinal center of the base plate 1 there are three support columns 12, which carry the stationary line transport station 7, with their essential individual parts in FIGS. 4 to 7 is shown.

The transport station 7 is stored with a storage slide system in each case 20 on the three next to each other transversely to the transport direction 5 standing support columns 12. It is designed such that they on line paths 9a of both feeders 4 in height a transport path 9c in which a selected line 9 to Line processing machine is transported, can act. Therefore, one line path can be seen in FIGS. 4 and 5 11, the feed device 4 and shown in FIGS. 1 to 3 the other line path 13 is arranged in mirror image other feed device, not shown, the conduction paths 11, 13 because of the V-shaped arrangement of the two Feeders also from the rear (line inlet side) run towards the front (line outlet side) in a V-shape.

The transport station 7 consists essentially of a means of transport for two lines 9 with a conveyor system 21a drivable belts or conveyor belts endlessly guided around pulleys, the belt conveyor system 21a horizontal, the means with vertically aligned roller axes and upright standing belt is arranged.

The belt conveyor system 21a has one between the in each a vertical line path level 129 lying line paths 11, 13 internally toothed conveyor belt or conveyor belt 14 on whose transport strand is actively working on the transportation of a line with some play between the tapered conduction paths 11, 13 sit and thus also run conically. The transport belt 14 wraps around the line outlet (in hereinafter referred to only on the outlet side) a drivable Gear 15 runs to the line inlet side (in the following only with inlet side or inlet side) with parallel to the line paths 11, 13 extending lateral Transport runs 14a, 14b to deflection rollers 17 and from there V-shaped to an inlet-side counter-bearing roller 18, which the Strap also wraps around. Between the gear 15 and the Deflection rollers 17 run the transport runs 14a, 14b between the support rollers 16 arranged on the strands 14a, 14b.

On both sides next to the transport belt 14 is a drivable horizontally displaceable perpendicular to the line path 11 or 13 mounted driving belt 19, 22 arranged. The driving straps 19, 22 have the same structure and are mirror images arranged to each other. They each loop around the drive gear 15 laterally adjacent drivable drive gear 23 and each run with a conveyor belt side Transport strand 24, 25 and an outside return strand 26, 27 to a deflection roller 28, the deflection rollers 28 to the deflection rollers 17 are arranged laterally adjacent. The transport strands 24, 25 are guided over support rollers 29.

The conveyor belt system stored on the central column 12 with the conveyor belt 14, the gear 15, the support rollers 16, the deflection rollers 17 and the counter-roller 18 is as a unit on a slide plate or a slide 30 of the Bearing slide system 20 mounted. The shift plate 30 is through a parallel displacement horizontally perpendicular to the Line paths 11, 13 (double arrow direction 31) can be moved guided stored so that the transport runs 14a, 14b vertically to a line path 11, 13 in a horizontal plane can be moved. This is used as a detail in FIG. 2 A recognizable sliding gate system supported on the support column 12 32, which is shown schematically as detail B in FIG. 4 and 5 is shown. The link slide system 32 has a sliding block plate arranged on the sliding plate 30 33 with an angled to lying in the mirror plane 21 Sliding axis 34 extending slot 35, the one from a fixed part of the sliding plate 30 slidably supporting Bearing plate system 20 arranged bolt 36 is penetrated. The sliding block plate 33 is on the inlet side of a slide rod 36 arranged with e.g. a pneumatically operated one Piston-cylinder unit 37 communicates. By pulling in the direction of the inlet side (arrow direction 38 in FIG. 4) Transport run 14a of the transport belt system by parallel displacement to the displacement axis 34 perpendicular to the line path 13 moved too. By pushing in the direction of the outlet side (arrow direction 39 in Fig. 5) becomes the transport run 14b of the transport belt system by parallel displacement to the displacement axis 34 shifted perpendicular to the line path 11 to horizontal.

For the same purpose, the two are on one side Support column consisting of 12 driving belt systems from the driving belts 19 and 22, the drive gears 23, the guide rollers 28 and the support rollers 29 with one each the slide system 20 slidably mounted slide plate or a sliding carriage 40 is arranged. The sliding plates 40 are each with a e.g. pneumatically operated, piston cylinder unit supported on the bearing plate system 20 41, each with a push rod 42 with the Sliding plate 40 is connected, in the double arrow direction 43 slidably such that the conveyor belts or conveyor belts 19, 22 with their transport strands 24, 25 horizontally perpendicular to the respective line path 11, 13 are displaceable. In the Transport station 7 are therefore the transport runs 14a, 14b, 24, 25 arranged parallel to the line paths 11, 13.

The drive gears 23 are during the operation of the feed device 4 continuously driven so that the transport strands 24, 25 keep running. The direction of rotation of the continuously running drive gear 15 changes or reverses each during the shift from a line path 11 to the other line path 13 such that each of the transport runs or conveyor run 14a, 14b of the conveyor belt 14 with the Transport runs or conveyor runs 24, 25 of the driving belts 19, 22 run in the same direction and at the same speed.

The drives are in accordance with this synchronization coupled, with telescopic drive shafts 44, insert their parts into each other in a rotationally fixed manner, underneath the drive gearwheels 15, 23 are connected to the drive gears and to a gear system arranged on the base plate 1 51 run (Fig. 6, 7). The drive shafts 44 enable each due to an upper universal joint 45 and a lower universal joint 46 and the telescopic displaceability an angle the drive shafts 44 when moving the belt systems in arrow directions 48, 49, 50 or 52, 53, 54 in particular also during the drive, that is, with rotating shafts 44.

The transmission of the transmission system 51 is located on the middle one Drive shaft 44 of the conveyor belt system fixedly arranged Gear 55 and a toothed belt 56 with a not shown Engine connected.

4 and 5 illustrate the changing conveyance of the funding or Transport station 7. In Fig. 4 it is shown that the Transport strand 14b of the conveyor belt system together with the Transport strand 24 of a drive belt system line 9 the conduction path 11 jams and promotes when the transport system is driven. In Fig. 5 it is shown that the Transport belt system moved parallel to line path 13 is offset to the axis 34 and the transport strand 25 of the other Driving belt system the transport run 14a of the transport belt system is switched on, so that a line 9 of the line path 13 can be funded.

The lines 9 are, as already described, in a vertical Level 129 at a distance above one another in line paths 9a or 11 and 13 held in the feed device 4. The two-part Mounted up and down mounted bracket consists of one in the transport direction 5 extending first inlet side Frame 57 and a second outlet-side frame 58, the transport station being between the two frames 57, 58 7 is located.

The frame 57 points from the inlet side to the outlet side in succession a vertical first spar 59, one on top of it End attached, horizontally extending traverse 60, one downwardly arranged second upper traverse 62 and a second vertical, arranged at the end of the second cross member 62 Holm 63 up. Is longitudinally under the cross member 60 a vertical intermediate beam 64 is provided on the cross member 60 and below the step edge 65 on the traverse set down 62 attached another vertical spar 66. The spars 66 and 63 are at their lower ends above a lower horizontal Truss 67 in a fixed connection, so that the trusses 65 and 67 with the spars 66 and 63 a first square frame 68 form, whose lower traverse 67 is approximately at the level of the bearing plate system 22 is located.

The frame 58 downstream of the transport station 7 has another square frame 69, which is about the same size dimensioned and arranged at the same height as the frame 68. The further frame 69 consists of the upper horizontal Traverse 70, the lower horizontal traverse 71 and the two vertical side rails 72, 73. Stand approximately in their longitudinal center the trusses 70, 71 with a vertical intermediate spar 74 in Connection.

The lower traverse 71 projects a bit beyond the attachment point of the vertical side member 73 and is telescopically supported a truss arm 75a, at its free outlet end a vertically upwardly extending nozzle bar 76 is arranged is. The connection between the truss arm 75a and the Nozzle strip 76 takes place by means of a joint, preferably one Ball joint, at least with a joint that is vertical Hinge axis. The meaning and purpose of the articulated arrangement and the telescopic storage is explained below.

In the spars 59, 64, 61, 63, 72, 73 and the nozzle bar 76 are for line paths 9a, 11, 13, respectively, aligned holes 77 provided so that the lines 9 in each of the feeders be stored horizontally. In the holes 77 of the spars 61 and 63 as well as in the spars 72, 74, 73 and the nozzle bar 76 stuck - forming the line paths - the ends of so-called Spring strands 78, which are tubular and made of Windings consist of helically wound wires. The spring strings are both flexible and stretchy. Instead of the spring strands 78, tubular strands can also be made another elastically bendable and stretchable material used become. The spring strands 78 stuck in the spar 72 are continuous to the nozzle bar 76 and are in the spars 74 and 73 and fixedly arranged in the nozzle bar 76 (FIGS. 8, 9). You can move a bit towards the transport station on the inlet side 7 protrude from the spar 72. The meaning and purpose of the elastic Tubes 78 will be discussed below.

The trusses 62, 67 and the trusses 70, 71 are with guides 79 guided up and down on vertical rails 80. The rails 80 sit on vertically standing, in the area of Side edges 2 of the base plate 1 arranged columns 81. Die Columns 81 are at their head end with a cross member 82 in Connection that continues on the outlet side and above the Nozzle bar 76 ends. The traverse 82 carries in the free end region a bearing arm extending transversely to the transport direction 5 83, on which also extends transversely to the transport direction 5 upper slide 84 on guides 85 across movably supported (double arrow direction 84a). Below the bearing arm 83 is on the base plate 1 also transversely to Transport direction 5 extending bearing bar 86 arranged, the a lower carriage 87 on guides 88 traversable stores. The slides 84, 87 are in a vertical zone arranged one below the other and standing above two vertical ones Rails 89, from which only that of the feeder 4 shown is because the other feeder is not shown together in connection. The other track of the second Feed device 4, not shown, extends parallel at a distance from the illustrated rail 89 and stored in the illustrated recess 90 of the carriage 84, 87. With this device, the rails 89 in the double arrow direction 84a are moved so that each nozzle 10 in front of the processing station 124 can be driven. A not shown is used for this Drive means, e.g. a piston cylinder assembly. In that the arm 75 is articulated on the bar 76 and elastically bendable and extensible spring strands 78 are used, the movability of the rails 98 is ensured.

The pillars 81 each carry a bearing block in the free end region 94, 95. The bearing blocks 94, 95 are rotatably supported one to the other bracket horizontally and parallel to the direction of transport 5 extending shaft 96. The shaft 96 passes through the bearing blocks 94, 95 each one piece, on the outlet side protruding end of a drive gear 97 followed by a drive transmission gear 98 and on the inlet side protruding end of a driving gear 99 are attached. in the The foot area of the columns 81 is vertically below the columns each drive gear 97, 99 a deflection gear 100, 101 rotatable stored.

A finite toothed belt 102 and is over the gears 99, 100 A finite toothed belt 103 is guided over the toothed wheels 97, 101. The upper end of the toothed belt 102 is at 104 on the crossbar 62 and the lower end of this toothed belt is at 105 on the Traverse 67 attached. Accordingly, the top of the Timing belt 103 at 106 on the traverse 70 and the lower end this timing belt 103 attached to the crossbar 71 at 107. in the Associated with this is the drive gear 98 from an endless belt 93 wrapped around, which led upwards a gear 92 Drive device of a motor mounted on the traverse 82 91 wraps around.

The drive device or the motor 91 rotates the shaft 96 and Depending on the direction of rotation, it raises or lowers vertically and synchronously the two frame frames 57, 58 with the lines stored therein 9 in the double arrow direction 116 and positioned in each case a predetermined line 9 between the conveyor belts fixed transport station 7. The transport device 7 is then used to transport the positioned line switched on and promotes a line section of this line the nozzle 10 of the nozzle bar 76. A the conveyed pipe section Corresponding line section is made at the same time the supply device on the inlet side into the feed device 4 drawn.

From the outside, that is from the side to the outside edge 2 of the base plate 1 has clamping holes 108 in it Spars 63 and 72 are inserted perpendicular to the line through holes 77 flow out. Each sits in the clamping holes 108 a known clamping device 109 with a clamping bolt 109a, which spring-loads a line located in hole 77 permanently clamped against an abutment 109b, the Clamping bolt 109a has a recess in the spring strand provided for this purpose 78 reaches through. In the amount of the conveyor run of the transport facility 7 is a pulling device 110 on each column 81 stored, which has a gripper 111 of a ring 114 the Can reach behind the clamping device 109. The gripper 111 is standing with e.g. pneumatically operated piston-cylinder unit 112 in connection such that the gripper 111 horizontally in the double arrow direction 115 can be moved back and forth to the spar. Thus, the gripper 111, if it has a ring or gripping projection 114 of the clamping device 109 has gripped and pulled will, unclamp the line 9. After opening of the gripper 111 can the clamping device 109 under its own Return the spring force to line 9 and clamp the latter again. The meaning and purpose of the clamping device is explained below explained.

The respective line paths having a plurality of lines 9 9a and 11, 13 of the two feed devices 4, of which only one shown in Figs. 1, 2 and 3 form one wedge-shaped interior 117. The line withdrawal station 8 is located each outside of this room and outside of the respective line paths 9a and 11, 13 in the area between the two spars 74, 73 (Fig. 8, 9). In the spars 74, 73 are the Spring strands 78 clamped. Station 8 has a vertical one Bearing ledge 120, which is attached to the cross members 70, 71. It supports a sheet-forming device 121, one in the direction Line path 11 or 13 arched projecting vertically Aligned cylinder section 122 which with a Push rod 123 slidable in a hole in the strip 120 supports, the push rod 123 on the of the cylinder surface facing section surface is arranged. The push bar 123 stands with the piston of a piston-cylinder unit 118 in Connection, which is supported on the bar 120 (not shown). The cylinder section 122 expediently has one Height that allows multiple conduction paths 9a, 11, 13 or To capture spring strands 78. The mouths of the nozzles 10 of the Line paths 9a and 11, 13 are in a vertical, plane extending transversely to the transport direction 5 (FIG. 8, 9). Located at the level of the transport run of the transport device 7 a knife device 124 of a not shown Processing device of a line processing machine, their inlet-side limitation in the level of the mouths of the Nozzles 10 is. Since the knife of the knife device 124 Distance from the inlet-side boundary are arranged, remains after cutting a line 9 with the knives short line protrusion 9b that emerges from the mouth of the nozzle 10 protrudes. This projection 9b interferes with the vertical movement the frame frames 57, 58; the cable ends can be crushed or be bent so that they are uncontrolled during the later advance against equipment of the line processing machine encounter, which leads to accidents. For this reason, the Line changes, i.e. during the opening or lowering of the frame frames expediently all lines shortly beforehand 9 of the line paths 9a and 11, 13 withdrawn into the nozzles 10. After positioning a new line in front of the processing device 124 of the line processing machine the withdrawal position of the lines 9 canceled again, so that all line ends with the respective projection 9b again protrude from the mouths of the nozzles 10.

The line withdrawal station works as follows (see Fig. 8, 9). If a line 9 is to be changed, the clamping devices 109 at least in the spar 72, expediently also activated in the spar 63 and the lines 9 clamped. The archery facility 121 is in the direction of the line paths 9a or 11, 13 advanced. The cylinder wall of the cylinder section presses arches directed towards the interior 117 into the spring strand areas 78a of the spring strands 78 which are located between the spars 74, 73 are located and clamped in the latter. The spring strand sections 78a bend and stretch elastically so that section 78a is extended. The lines 9 in the Spring strands 78 from the clamp 109 to the mouth of the nozzle 10 freely movable, also form an arch in the Bow area of the spring strand areas 78a, which makes the straight axial extension length of each line 9 is shortened so that the free ends of the lines 9 are withdrawn into the nozzles 10 become. Thereafter, the frame frames 57, 58 are moved to the mouth of the nozzle of a selected line 9 before Input of the processing device 124 of the line processing machine located. Then the cylinder section of the Retracted sheet forming device, the bent Spring strand sections 78a under the action of their elastic Restore restoring forces to a straight distance and shorten and push out the elbows so that the Line ends from the mouths of the nozzles 10 with their projection 9b can be pushed out.

A line withdrawal station thus works according to a line deflection process, with the one line from her straight axial orientation is deflected, being in the transport direction is clamped before the deflection, so that in the direction of transport line end arranged after the recess in Withdrawn in the direction of deflection or against the direction of transport becomes. The shape of the deflection can be any. The return of the line end can be done by canceling the deflection when using the effect of inherently elastic forces Management. But it can also by the action of the deflection be done by the deflection line from the deflection back to the starting position or press. As described above, one is advantageous To use deflection device that is elastic when deflecting Restoring forces developed in themselves when the deflection force is canceled the deflection device back to its starting position spend and also the deflected line in its starting position to lead. So you can do it with very little effort and short routes of retreat, the line change without problems and execute quickly.

As described above, two feeding devices can be put together with a single, not shown Line processing machine work together, of which only hinted in Figures 8 and 9 part of a cutting device 124 is shown. The arrangement of the two feeders creates the possibility of switching in one Prepare feeder while from the other feeder still lines in the line processing machine be promoted.

The transport station 7 is an inlet side according to the invention Line straightening station 6 upstream, which as usual consists of two Straightening roller sets 6a, 6b. Each straightening roller set 6a, 6b has an upper and a lower roller conveyor 127, 128 with each Throat rolls arranged one behind the other in the transport direction Straightening rolls 125 on. The straightening rollers 125 are rotatable roller axes 126 arranged perpendicular to the transport direction 5, the axes 126 of the lower roller conveyor 128 to the axes 126 of the upper roller conveyor 127 in the transport direction Path length "a" are arranged offset to each other (Fig. 14).

The fillets of the rollers 125 of the roller conveyors that are driven against one another 127, 128 form a conduit in transport direction 5, through which a line 9 fits. The channel diameter is set to the diameter of the line 9 or to the line type, which should be processed.

It is essential that those lying perpendicular to the transport direction 5 Axes 126 of straightening rollers 125 are not horizontal or vertically but with an angle β (FIG. 11) of preferably 45 ° to the vertical plane 129, in which the conduction paths 9a or 11, 13 are arranged inclined, with all axes 126 of a straightening roller set 6a or 6b are parallel to one another and the axes 126 of the straightening roller set 6a to the axes 126 of the straightening roller set 6b are aligned vertically. Out the inclination of the axes 126 results in that the Disc levels of the disc-shaped straightening rollers each with a corresponding angle α (Fig. 10) inclined to the vertical plane 129 are aligned.

The straightening roller sets 6a, 6b are identical.

The lower roller conveyor 128 of the straightening roller set 6a is stored in the roller-side free upper end area of a carriage 130 (Fig. 14), with the axes 126 of the rollers 125 in the transport direction 5 sit in side-by-side bearing blocks 131 and the bearing blocks 131 in the free end region in each case in one Run out guide web 132, which is beveled on the roller side towards the roller are so that an insertion funnel 133 for a line 9th is formed. The guide webs 132 engage between the Bearing blocks 131 provided gaps 132a. The rollers 125 are stuck in the transport direction 5 extending slots 134 of the Bearing blocks 131, their groove in the insertion funnel 133 flows. The carriage 130 is on a guide system 135 in the double arrow direction 136 on a slope to the vertical plane 129 slidably mounted and by means of a not shown Drive, e.g. one supported on the guide system 135, pneumatically operated piston-cylinder unit in the double arrow direction 136 procedure. The guidance system 135 is on one Bearing plate 137 attached, which in turn on one on the Base plate 1 arranged storage frame 138 rests (Fig. 3).
