Abstract

In order to transport cans (44) between machines (30, 11, 110) treating or processing fiber webs by means of a can transport device (26), the latter is loaded and unloaded at the same time in a position on a machine (30) or a store (5). During their transport between two such machines (30, 11, 110), the cans (44) are checked. Here, the cans (44) still containing the remains of fiber webs are emptied. The path (901, 902, 903) of the can transport device (26) forms a track system consisting of three interconnected can circuits, where a first circuit comprises two such machines (11, 110, 30) and the other two one of these machines (11, 110, 30) each and the can store. The can shifting device for loading and unloading the can transport device (26) is fitted with a grip to grasp the can (44) and a lifting device to raise the grasped can (44). The grip (72) is arranged on a slide movable transversely to the longitudinal extension of the can transport device (26) which in turn is arranged on a carrier slide movable transversely to the longitudinal extension of the can transport device.

Description

The present invention relates to a device according to the preamble of claim 1.

The problem arises for automatic transport Jugs with a can transport from a sliver machining or processing machine or such a device to another such machine or device bring. From one route it is known, can transport to position on the route on which the cans be pushed out of the filling position (DE-PS 1.265.014). The Can transportation (wagons) are then divided by can moved on to push out the next cans to be able to. This has the disadvantage that the can transport generally has to change its position when it delivers empty cans, before it can take the full cans. This is not only cumbersome with regard to the corresponding drive and Guiding devices to the car, but also space-consuming. Another problem with an automatic Processing between two or more slivers Machine or device occurs is that this Machine or devices of all kinds can be so the need for cans or the dispensing of cans is also different.

DE-U-88 12 622 describes a ground vehicle for transporting Flat cans with a can offset agent for the exchange of Flat cans shown in the direction of their longitudinal axis. The Can offset means is equipped with a gripping means. The Jug offset means is a fork-shaped gripper that holds the jug slightly resilient and therefore easy to hold. This gripper has the Disadvantage that a change in the outer contour of the can it is no longer possible to grasp the jug safely. The light grip that the gripper exerts on the jug is often no longer sufficient, to safely pull the jug from the spinning machine onto the cart. In such a case, it is necessary that in a time consuming Way must be reworked manually.

The object of the present invention is an automatic Can transport system to create the way of working on and / or between the sliver working or processing machines or Optimize devices and thus at a time and / or space saving to lead.

Starting from the device according to DE-U-88 12 622 this task by the characteristics of the characteristic Part of claim 1 solved.

To avoid different methods of loading and unloading of the can transport means for the different, connectable via the can transport means, Sliver processing or processing machines or devices, is advantageously always only a full / empty one Jug loaded and at the same time an empty / full jug unload. In this way, one and the same loading or unloading device for loading and unloading at each of these different Sliver processing or processing machines or Devices are provided.

With long spinning or twisting machines, it is particularly difficult Replacing cans, as opposed to other machines (e.g. stretching) the cans through the machine or device wander through and always in the same place fed to the machine or device and to another, likewise unchangeable place of the machine or device can be removed again, but to ensure optimal working of machines connected to each other and / or via the can transport It is provided according to the invention to enable devices that at least two pitches on the can transport be provided, of which at the beginning of a Jug exchange a jug parking space is empty that the one to be replaced Jug from one on the machine or device provided can space, which at the same time can delivery point and can delivery point is on this empty can parking space is loaded and then the can transport with a can to be exchanged for a can to the full can space of the machine or Device moves and unloads the can to be exchanged, so that on the can transport again a pitcher space becomes free. Simple movements during loading and unloading To get it, it is advantageous if the loading and / or unloading process essentially without lifting and lowering the jug. The loading and / or unloading process is essentially only a translational movement of the can. It is particularly advantageous if separate loading and Processing or processing unloading devices on the individual slivers Machines or devices are unavoidable, if then the loading and / or unloading process on the can transport is carried out.

Especially when the can exchange by moving takes place, are advantageously abrasion-resistant sliding edges on the Jug shelves and / or provided on the jug bottom, wherein these abrasion-resistant sliding edges are expediently made of polyethylene consist.

In principle, the can transport means can be designed differently be, for example, as a hanging on a rail Dare. However, it is particularly advantageous to use the can transport means train as a ground vehicle. In one Fall, it is particularly advantageous if the pitcher footprint on the sliver processing or processing machine or device as one in height to the can space of the can transport adapted platform is formed.

To load and unload the can transport center at the same time can, it is possible to use two separate, synchronous can offset means to provide, one of which, for example the can delivery point and the other at the can delivery point is arranged. However, one is advantageously one Can offset means provided, which is divided into one Partial offset means for unloading a can from the can transport means and in a partial offset means for charging a can on the can transport. Such training of the Can offset agent can also be used to advantage be brought when loading and unloading the can transport not happening simultaneously, and regardless of whether or not a can store is provided. Such Training of the can offset means is also independent of the Number of slivers accessible by the can transport working or processing machines or devices and of the presence of a test station. Also the relative height arrangement of the different pitches or does not affect the formation of the can offset.

By dividing the can transport means into two partial means of offset on the one hand, it is possible to use this partial offset in one and the same, transverse to the path of the can displacement means provided level so that the can exchange in one and the same level.

The can transport means preferably has in the direction of travel consecutively at least two pitches for receiving from a jug each. This also makes it possible for the two Partial offset in two across the path of the can transport Arrange arranged levels that are spaced from each other the width of a can space are arranged. This allows z. B. on spinning and twisting machines, at a job to bring a jug into its working position and to take a jug from the neighboring spinning station and onto the Can load transportation.

If two partial offset means are provided, then these can can also be designed to be controllable independently of one another.

With spinning or twisting machines or with various others Sliver processing or processing machines or devices can pitches are provided, which are also can delivery points and can delivery point. In one Case is advantageously provided according to the invention, that the distance between those on the can transport Pitches is essentially the same size as the distance between the pitches at each other Sliver processing or processing machine or device.

The can offset means can be designed differently. According to an advantageous embodiment of the invention, the can offset means with a gripping means for grasping a jug equipped near its lower end. It is advisable to ensure that the jug works safely at the bottom, a resolution to work with the gripping means. It is advantageous if the Jug is designed as a flat jug that this attachment in the end, i.e. on the narrow side, the flat jug is located, whereby it is particularly useful to use both ends of the can, i.e. on two narrow sides, each to provide such an attachment. Such an attachment is in accordance with a preferred embodiment of the subject of the invention designed as a bracket.

According to a preferred embodiment of the subject matter of the invention the can offset means is equipped with a gripping means, the one on a transverse to the longitudinal extent of the can transport sliding carriage is arranged, which in turn preferably on a transverse to the longitudinal extent of the can transport movable carriage is arranged.

If it is inevitable that the pitches on the Can transport and on the sliver processing or processing Machine or device arranged at different heights are, according to the invention, the can offset means a gripping means for grasping the can and with a lifting device equipped to lift the detected jug. To this The purpose is preferably the gripping means on a vertically movable Arranged lifting column.

In principle it is irrelevant where the can offset means are arranged is, but it is particularly advantageous and space-saving, if this is arranged on the can transport means, because in this way a single can offset agent for all machines that can be approached by the can transport means Devices are sufficient.

The can transport means preferably has two can parking spaces on which each have a separate can offset means is. Around the can transport means without turning around Use 180 ° for both long sides of a spinning or twisting machine To be able to, is conveniently the can offset for the exchange of cans either in one or the other Movable transverse direction of the can transport.

For optimal control of the can transport means and thus it is special for optimal can disposal and supply advantageous if the slivers are working or processing Machines or devices as well as the can transport to control the can transport with a common one Control device are connected. This common control device thus determines the order of the individual works and in this way ensures that there are no downtimes occur, but each time in time pitchers for the further Continuation of work on the various machines and devices be available.

The control device can use a normal computer go out and along the way for the can transport arranged, non-contact transmitters have the a corresponding, non-contact receiver work together on the can transport. Advantageously are the transmitter and the receiver as infrared devices educated.

There are a large number of cans in spinning or twisting machines to be arranged side by side. Such machines have a large number similar jobs next to each other, from these Pots need to be supplied so that it is necessary for everyone Assign a jug to each job. So far this is only possible by arranging the cans in two rows. Around to avoid this is provided that the cans as Flat cans are formed and the can transport means across is movable to the longitudinal extent of the flat cans.

It has proven to be particularly expedient if if flat cans are to be transported, the can storage extends transversely to the longitudinal extent of the flat cans. On the other hand it is useful to replace the pitchers parallel to Longitudinal extension of the on the can transport or in the can storage to move the flat cans.

The flat cans are designed according to the invention so that their Width essentially the width of a job Corresponds to the spinning or twisting machine and its dimensions are chosen so that the capacity of the flat can Capacity of one used in spinning or twisting machines Round can corresponds. In this case it is possible to Arrange cans on the machine in a single row. Here it is advisable to dimension the flat cans in such a way that the capacity of the flat can essentially corresponds to that of a round jug with a diameter of 450 - 500 mm. It has been shown that it is sufficient for this if the length of the flat can essentially four times its length Width is.

Finds a flat jug in connection with one of the jug contents sensor application scanning through a window, the flat can advantageously has both of them Narrow sides of a window so that it doesn't matter which narrow side is delivered to the sensor.

It has proven to be useful for proper loading and unloading proved the jug with a loose, by the action of floor that can be raised on the outside.

As "sliver processing or processing machine" in the sense of present textile machine should be understood the slivers treated or processed. These include e.g. B. Draw frames and spinning machines such as ring, air, False-wire and open-end spinning machines, but others can too Textile machines fed with slivers for processing will be suitable, such as. B. circular knitting machines for the production of pile fabrics and carpets be fed. Work organs can thus a carding device (with a card), a drafting system (e.g. with a Draw frame or air spinning machine), a spindle (e.g. with a Ring spinning machine), a spinning element (spinning rotor etc. of an open-end spinning machine), a needle cylinder (in a circular knitting machine) and the like. The place where these working organs is referred to below as the job. Usually has a textile machine in which the subject of the invention Can be used more than one job, d. H. more than just a "sliver working or processing Device ", but the invention is not limited to this.

For the purposes of the present invention, each “ Sliver composed of fibers are understood to be independent whether the sliver has a certain twist, as is the case with fuses or not.

The invention enables the exchange of Cans on sliver processing or processing machines or Devices and the transportation of these cans between such Machines or devices. The optimization is done by various measures on these machines or devices themselves or between them. The claimed Device features enable significant automation of the can transport by the can exchange to the Spinning stations runs faster and safer, as well as one Balancing the work cycles at the different, with each other machines connected via a means of transport or Devices by working or processing between the slivers Machines or devices that are not at the moment cans needed and / or to be checked be checked and / or on another machine or device are needed. The efficiency of such The machine system is thus increased.

As already mentioned above, the subject of the invention can be combined processing or processing with different slivers Textile machines or devices find application; below are initially in a striking embodiment a conventional open-end spinning machine 1, from card 3 and one Serve route 30, which are now described with the help of Figure 1 will.

The loading device of the card 3 is for clarity not shown for the sake of it. Card 3 supplied by a filling head, not shown, a can 40, which as well more cans of route 30 is fed (see route 90). in the Embodiment shown are a stretching head 301 six Slivers 400 to 405 fed from cans 410 to 415 be removed. The thickness of the delivered sliver corresponds the strength of the individual slivers fed 400 to 405. On each side of route 30 are in one second row reserve cans 420 to 425. The slivers are guided above a belt guide table 300. Because of closer For details, see U.S. Patent No. 4,838,018.

The newly formed sliver (not shown) is replaced by a Filling head 31, which is part of the line 30, filled into a can 43, after it has been filled, out of the stretching head 301 is moved out. The can 43 then becomes one Open-end spinning machine 1 (see route 900).

An open-end spinning machine usually has a large number juxtaposed work or spinning stations 10, the on one or both sides of the open-end spinning machine 1 are arranged. Each spinning station 10 is conventional Formed and has a spinning element, for. B. one Spinning rotor, to which a sliver 4 is fed so that this in is known to be spun into a thread (not shown).

In the device shown in FIG. 1, the cans have 43 such a dimension that they are side by side over two horizontal spinning positions 10 extend. For this reason, that every second spinning station 10a has a can 43a first row of cans a and each intermediate spinning position 10b a can 43b is assigned to a second row of cans b.

It turns out that with such a can group 430, consisting of a can 43a and a can 43b, the sliver 4 threatens to run out, a corresponding impulse is sent to the Given control device of the open-end spinning machine 1, the then causes as soon as possible behind the two cans 43a and 43b in a third can row c a can 43c as Reserve pot is provided in a waiting position. Such as then the can 43a or 43b, from which for spinning continuously sliver 4 is removed, has expired, then the sliver 4 from the can 43c into the corresponding feed device (not shown) due to the sliver running out 4 stopped spinning station 10a or 10b of such Spinning station pair introduced.

The third can row C thus forms a can store for the can 43. FIG. 2 shows another embodiment, in which one of two can stores 50, 51 Composite can storage 5 is provided.

Figure 2 shows schematically a part of a system with a Line 30 and two spinning or twisting machines 11, 110, one of which only part of their longitudinal extension is shown. The line 30 has a filling head 31 and can storage 50, 51, which will be described in more detail later. The inlet 302 the route 30 is for cooperation with, for example, six round round cans 410 to 415 (sixfold doubling). The spinning or twisting machines 11, 110 each have one End head 12 that is near a predetermined connection path (Path 901 - shown in dashed lines) is arranged. The way 901 arrives at the exit of route 30, so that Can transport means 2 positioned between the can stores 50, 51 can be. The path 901 can e.g. B. by on Guideline marked on the floor (optical sensors) on the vehicle or through an electrical conductor installed under the floor (inductive sensors) on the ground vehicle Can transport means 2 are formed. So you can along the way 901 for the non-contact can transport Transmitters (not shown) may be provided, e.g. Infrared devices, those with a corresponding contactless receiver Work together (not shown) on the can transport means 2.

A can store is the in this embodiment Spinning or twisting machine 11 or 110 not assigned.

Two each extend along the path along the machines 10, 110 901 connected branches (paths 902, 903), the two Branches near the machines 50, 51 and parallel to each other and run to the machine longitudinal directions.

If the spinning station 10 (see Figure 1) with a to be replaced Jug in the row of spinning positions closer to route 30 the spinning or twisting machine 11 lies, receives the Can transport means 2 through a can requirement indicator 85 - which will be described in more detail later - the spinning or twisting machine 11 a driving order, which commands him, after leaving to follow the route 30 for the time being and then the route 901 then to branch off from this path if it is that of the spinning or Thread 903 assigned to twisting machine 110 is reached. This is at the arrangement of Figure 2, the third branch. This will the can transport means 2 in this way on the spinning or twisting machine 11 moves along it by proper positioning the desired can exchange method in the longitudinal direction of the machine without any further approach to the machine 11 can run. The same applies to the machine 110 if the can transport means 2 receives a travel order, around the path 902 of this spinning or twisting machine 110 to move.

The path 901 can, as indicated, be extended by the To connect route 30 with other machines or machine sides. It may also be different machines Act kind.

A machine arrangement according to FIG. 2 can be of the spinning or Twisting machines 11, 110 can be controlled by each machine via a signal line (not shown) to route 30 is connected and sends "delivery orders" to route 30. The route 30 extends such delivery orders to the Can transport 2 further, for. B. if this compared to the Route 30 is in a can receiving point. The Can transport 2 itself can with sufficient intelligence (Computing capacity) are provided to the "delivery orders" convert into "driving orders" and these driving orders accordingly to execute. More details will be described later in detail.

A training of a can demand detector 85, which at each Spinning or twisting machine 11, 110 to be provided per spinning station 10 is explained with the aid of FIG. This figure shows a delivery roller 14 of an open-end spinning machine 1 (see figures 1 and 3), for example, via an individual drive 140 is driven, but this type of drive plays no role, so that a common drive for several side-by-side spinning stations 10 (see Figures 1 and 3) can be provided. Located on the delivery roller shaft 141 there is a switching flag 850, which when rotating the delivery roller shaft 141 periodically in the area of a light barrier 851 arrives between a light source 852 and a photocell 853. The photocell 853 is connected to a control device via a line 854 855 of the open-end spinning machine 1 in connection, which in turn via a data line 81 with a control device 8 related, to which later will be received.

The control device 855 together with the light barrier 851 forms a measuring device. If through the switch flag 850 a certain number of pulses have been delivered - that of a certain length and thus a certain consumption of the sliver 4 corresponds - so the control device triggers 855 the open-end spinning machine 1 via the data line 81 in the control device 8 from a pulse from the control device 8 processed and as a request for a full jug 43 or 44 is understood. The control device 8 can on the can transport means 2 itself - as above described - or be arranged stationary - as later in Connection with Figures 14 and 15 will be explained becomes.

To avoid having to replace the new jug too early, namely when the sliver 4 is on the concerned Spinning station 10 located jug is not yet completely used up has been in front of the delivery roller of the relevant spinning station 10 shows another light barrier 856 between a light source 857 and a photocell 858 are provided. The photocell 858 is standing with the machine-side control device 855 in taxable Connection, either directly with the can transport 2 is connected or via the central control device 8 the actual can exchange at the spinning station 10 causes when the incoming into the spinning station 10 Sliver 4 runs out.

The can transport means 2 with which the can requirement indicator 85 can be connected, is either on one of the machines installed in a system or on the Path between these machines, e.g. a route 30 and one Spinning or twisting machine 11 or 110 or between one of these machines and a can storage (e.g. can magazine 600 or 601), which - as shown in FIGS. 14 and 15 - also can be arranged independently of these machines.

Another can requirement indicator 86 is shown in FIG. 22. The can requirement indicator 86 is designed as a sensor and scans the content a jug, e.g. a flat can 44, and is over a Line 860 with the machine-side control device 855 (see Figure 21) connected.

So that the can demand indicator 86 detects the can content, i.e. the inner the can, can determine, the flat can 44 has on it Narrow side of a window 446, which is in the embodiment shown essentially over the entire can height extends and closed by a transparent insert is to impair sliver placement or removal to prevent. If the sliver 4 the bottom of the Window is reached, the can demand indicator 86 is addressed, which then triggers the further measures - as described.

So that the can requirement indicator 86 does not have to be movably mounted, in the exemplary embodiment shown it is arranged on the side of the can facing away from the operating side. This is illustrated in FIG. 22 by an arrow P ₇ , which indicates the direction of delivery of a jug to its workplace.

In principle, a small window at the bottom of the Flat can 44 is sufficient. However, at different lead times from the request for a flat can 44 as a result of the response of the Provide cans needs 86 and the cans exchange an elongated window 446 is required so that by changing the height setting of the can requirement indicator 86 relative to flat can 44, i.e. by vertical adjustment of the Can demand detector 86 along the window 446, the desired Lead time can be selected.

In the case of round cans 43 (see FIG. 1), a window 446 is sufficient. With flat cans 44, it is advantageous if on both narrow sides such a small window at the bottom of the can (not shown) or a practically the entire can height extending window 446 is provided because then the Flat can 44 optionally with one or the other end in it Working position and thus in the tactile range of the can requirement detector 86 can be brought.

Similarly, can demand detectors can also be used on others Sliver 4 processing or processing machines or devices be provided.

In the embodiment shown in Figure 2, the Pans in which the sliver 4 is placed are not round Profile, but are elongated (flat can 44). Your Both long sides (side walls 440, 441) can thus be used as a guide serve as will be described later. Can also the cans 44 are dimensioned so that per work or Row of spinning positions of the spinning or twisting machine 11, 110 only a single row of cans must be provided (see row of cans a in Figure 1).

The flat can 44 shown in FIG. 2 has two arranged in parallel Side walls 440, 441, which define the can width B. The flat can 44 also has two end pieces 442, 443, which connect the side walls 440, 441 and the Define can length L. In Figure 5 are rounded end pieces 442, 443 are shown, but these are also perpendicular instead of round the side walls 440, 441 or formed as a polygon could be. The pitcher length L is significantly longer (e.g. three up to four times larger) than the can width B, which is essentially corresponds to the width of a work or spinning station 10. In this way, i.e. by essentially four times the width of the flat can, it is achieved that the capacity of the flat jug (flat jug 44) the capacity one commonly used in spinning or twisting machines Round can corresponds.

The capacity of a flat can 44 should be as possible Capacity of a round jug (e.g. jug 43 from Figure 1) with a diameter of 450 to 500 mm. If as Example is assumed to be the diameter of a common one Round can is approx. 457 mm, then a flat can has 44 Figure 5 with a can width B of 230 mm and a Can length L of 780 mm a slightly larger capacity than the round jug. In other words, the length (can length L) of the Flat can 44 does not have to be twice the round can diameter amount to give the same capacity.

The height of the jug (round or flat jug) is determined by the construction given the spinning or twisting machine frame, because the cans 43 and 44 are placed under the spinning station have to.

As Figures 1 and 6 show, are a can delivery point 500 of the can store 50 and the can delivery point 511 of the can store 51 close together and on the path 901 of the Can transport means 2 arranged. The can transport 2 has a can receiving part 20 and two end parts 21, 22. Each end portion 21, 22 carries a post 210, 220, which in turn carry a bar 23, which acts as a guide rail serves for a can offset means 7. The can offset agent 7 is movable in the longitudinal direction of the bar 23 and thereby the individual flat cans 44 on the Can transport means 2 deliverable. The can offset 7 comprises its own rail 710, which is perpendicular to the beam 23 stands and serves as a guide rail for a can slide 71 (see Figure 3). The can slide 71 of Can transport means 2 comprises a gripping means (not shown), which is caused by a movement parallel to the longitudinal extension of the can and across the direction of travel of the can transport 2 the flat cans 44 from the can transport means 2 in the Can delivery point 500 on route 30 pushes and at the same time a second flat can 44 from the can delivery point 511 pulls on the can transport means 2.

Each end part 21, 22 of the can transport means 2 has wheels 24, what movements of the ground vehicle in the embodiment shown trained can transport means 2 perpendicular to Long side of the recorded flat cans 44 allows. The Can transport means 2 has a drive (not shown) and possibly a controller, which a steering system (not shown) controls for the wheels 24.

When the can transport means 2 leaves the route 30, it is loaded with ten full flat cans 44, the space for Inclusion of an empty jug remains free.

To enable a single can exchange, is on the Can transport means 2 to provide a number of pitches, which is between two and twelve.

Are too many pitches in a row on the Can transport means 2 provided, this is too large and is - especially in the curves and on the branches - very difficult to maneuver.

If there is only one can space, this means that one jug must first be unloaded before another is picked up can be. This leads to the fact that in machines, which the can delivery point can also deliver the can is, as is the case with the long spinning or twisting machines 11, 110 the case is after picking up the empty jug through the Can transport means 2 the unloaded full can still Bringing the final job is what is automatic is difficult to do. An appropriate number of Can positions on the can transport means 2 is therefore - as mentioned - between two and twelve.

FIG. 14 shows an embodiment of the can offset means 7 the rail 710, on which a can slide 75 is slidably arranged which in turn is two gripping means 726 and 727 having. The right can (flat can 44) was initially on a pedestal 530, which is on the same level as "N" another platform 53 and the upper edge of the can receiving Part 20 of the can transport means 2 is located. Furthermore are the platforms 53 and 530, which are part of the can storage 50 and 51 are arranged according to Figure 6, so that by a simple Translation movement by means of the gripping means 727 flat can 44 located on the right on platform 530 the can transport 2 can be spent while at the same time with the aid of the gripping means 726 the can transport means 2 flat can 44 on the Podium 53 is brought. Both offset movements thus take place together by a single movement of the can slide 75, so that the loading and unloading process without lifting and lowering the jug (flat jug 44).

Depending on the design of the can storage 50 or 51, it may be possible be that one movement alone as a translational movement or other horizontal movement is carried out, e.g. the can unloading while a combined one for loading Translation / stroke movement may be required. For example this is the case if both can stores 50 and 51 are designed as roller conveyors on which the empty or the full cans (e.g. flat cans 44) due to a corresponding Inclination automatically in the delivery point 501 or in the Can delivery point 511 slide. In this case there are naturally the can delivery point 500 and the can delivery point 511 at different heights, so this difference in height at least at one of these points when loading or unloading must be compensated.

In the described embodiment, the two can storage devices are used 50 and 51, jugs that are not needed immediately, caching. For example, at route 30 an empty, from a spinning or twisting machine 11, 110, e.g. an open-end spinning machine 1, or another textile machine, e.g. a circular knitting machine for the production of plush or carpet goods, brought can (e.g. a flat can 44) in the can storage 50 temporarily cached until the route 30 is able to fill this pot. On the other hand, remains a newly filled jug in the can storage 51 until it from the sliver 4 processing or processing machine or Device is needed.

The exchange of the empty for a flat can 44 to the same Time in the same work cycle is not the same as in the figures 2 and 6 shown U-shaped arrangements of the can storage 50 and 51 restricted. Further arrangements are in the figures 7 and 8 are shown schematically.

FIG. 8 shows a linear arrangement of the can stores 50 and 51 across the path 901 of the can transport means 2, one Flat can 44 by an arcuate movement from or to the can transport means 2 must be moved. Here is can transport - just like that in the figures 2 and 6 embodiment shown - in the central plane between the two can stores 50 and 51, but not parallel to these, but in a perpendicular to the longitudinal extent of the two can stores 50 and 51 located level.

As long as the can transport 2 - as in the in the Figures 2, 6 and 8 embodiments shown - themselves in the middle plane between the through the longitudinal extension of the Can memory 50 and 51 set memory levels is located as long as a similar movement of the same size can occur simultaneously for both loading and unloading the can transport be provided. In other words, it is required for this simultaneous unloading and loading of the can transport 2 that the can delivery point 500 and the Can delivery point symmetrical to that in the can exchange position located can transport means 2 arranged are. The simplest loading and unloading movements are included reached when the two can storage 50 and 51 and the Route 901 of the can transport means 2 in the area of these can stores 50 and 51 run parallel to each other, as shown in Figures 2 and 6 is shown.

Figure 7 shows another linear arrangement of the can storage 50 and 51, but in contrast to the exemplary embodiment shown in FIG. 8 parallel to route 901 of the can transport 2 and transverse to the longitudinal extent of the flat cans 44. Die zu Filling flat can 44 is the filling head 31 of the route 30 fed to the can store 50 from the same side which later filled the flat can 44 back into the can storage 51 is delivered. Such training requires that the can delivery point 500 and the can delivery point 511 at the opposite ends of the can storage 5 are located. In order to simultaneously load and unload the To be able to carry out can transport means 2, it is necessary the can offset means 7 (see Figures 3 and 6) in two partial offset means are divided by a corresponding one Control are synchronized with each other.

According to Figure 3, the can offset means 7 on the Can transport means 2 arranged, but this is not mandatory Prerequisite for changing the can, In particular when the can storage device 50, 51 is designed 7, a stationary arrangement of the in two Partial offset means divided can offset means 7 very advantageous be. A partial offset is used for unloading of the can transport means 2, while the other partial offset means serves to load the can transport means 2.

Depending on the arrangement of the can storage 50, 51 to each other and / or to can transport means 2 it is possible - e.g. at a Execution according to Figure 6 - the two partial offset means (not shown) also in one and the same working plane across To arrange path of the can transport 2.

FIG. 9 shows a device of the type shown in FIG. 7 is shown schematically, in more detail. The two can stores 50 and 51 are can offset means in the form of Conveyor belts or chains 502 and 512 assigned that immediately next to another conveyor belt or another Transport chain 32 with the aid of deflection rollers 503 or 513 be redirected. The conveyor belt or chain 32 extends from the can store 5 to near the Filling head 31 of the line 30 and 320 by pulleys redirected. The transport chain 32 drives a driver 321, who attacks the flat can 44 and this into the area the filling head 31 transported where the flat can 44 through two arms 33 of a can offset means designed as a traversing device be taken over. Arms 33 are out of range the flat can 44 can be pivoted back so that the flat can 44 through the conveyor belt 32 to the traversing area Route 30 can be brought, and are also mutually exclusive movable and form a gripper to the flat can 44 firmly to be able to clamp between them. The traversing device is necessary because in contrast to storage in round cans through the storage head of the line 30, the sliver 4 does not can be evenly distributed in the flat can 44.

To the traversing movement required for filling a flat can 44 is required not to interfere with the transportation chain 32 from the traversing area of line 30 to the basic position, in which the driver 321 is located on the route 30 facing away from the can store 5, retracted.

It is a further transport chain 34 with a driver 341 provided, which is deflected by deflection rollers 340.

The deflection rollers 320 are arranged so that the driver 321st from the side of the can store 5 facing away from the route 30 to accommodate a flat can 44 in the immediate vicinity of the Filling head 31 can be brought so that the flat can 44th then can be taken over by the arms 33. The Deflection rollers 340 of the transport chain 34 are arranged so that the flat can 44 by the driver 341, which is initially is located on the side facing away from the can store 5 until in the can store 5 can be returned. Are there the transport chains 32 and 34 over a certain length range arranged parallel to each other so that the effective range overlaps. The two transport chains 32 and 34 form together a can offset means for delivering and removing a flat can 44.

The can store 5 has a horizontal can footprint, thus the can delivery point 500 and the can delivery point 511 are at the same level. In this way it is not necessary either at the can delivery point 500 or at the can delivery point 511 or at both of these Deliver with can transport means 2 to height differences overcome. The conveyor belts or chains 502 or 512 are in the embodiment shown as support elements trained and have no carriers like the transport chains 32 and 34, which only work as tension elements. For this reason, the transport chains are 32 on both sides and 34 roller conveyors 35 arranged with a plurality of rollers 350, on which the flat can 44 slides well. Alternatively it is also possible to use driven conveyor belts or chains instead To provide roles.

Figure 10 shows a detail of Figure 9 in view B-B. How are recognizable by the transitions between the conveyor belts or transport chains 502 or 512 of the can store 50 or 51 and the transport chain 32 each filling the space Filler pieces 52 and 520 are provided to ensure that the Flat cans at the transition from the can store 50 into the area the transport chain 32 or in the transition from the area of Transport chain 32 in the can storage 51 no tilting movements can execute.

As already stated, the filled flat cans 44 are closed the spinning or twisting machines 11, 110 (see Figure 2), z. B. to bring to the open-end spinning machines 1 (see Figure 1) exchange them for empty flat cans 44. To describe this in more detail to be able to, reference is made again to FIG.

FIG. 3 shows twenty-three of an open-end spinning machine 1 Spinning stations 10 and a can transport means 2 for transport and to exchange flat cans 44 at the spinning positions 10th

The can receiving part 20 of the can transport means 2 is divided into compartments 201 by partitions 200, each Compartment 201 for receiving a flat can 44 by movement the flat can 44 is suitable in its longitudinal direction.

The can offset means 7 is by moving in the longitudinal direction of the bar 23 the individual compartments 201 of the can receiving Part 20 deliverable.

During the exchange movements of the flat can 44, these become open the can transport means 2 through the partitions 200. Also in the open-end spinning machine 1 (or other types Spinning or twisting machine 11, 110) become the flat cans 44 through guides 130 and 131 near the top and / or bottom End of the flat can 44 out.

The can transport means 2 is controlled by an investment control system, which will be discussed in more detail later, at a selected spinning station 10 performed, in which the flat can 44 is to be replaced. By a suitable positioning system (not shown here) the can transport means 2 initially positioned such that its empty compartment 201 is aligned with the spinning station 10, where the flat can 44 is to be replaced. The can offset agent 7 becomes the empty compartment 201 of the can transport means 2 assigned, and the can slide 71 is towards the machine moved so that its gripper (not shown) the one to be replaced Empty jug 44 can capture. By moving the Can slide 71 away from the machine is the one to be replaced Flat can 44 in the previously empty compartment 201 of the Can transport means 2 pulled (see Figure 12).

The can transport means 2 is then moved to one with a full flat can 44 occupied compartment 201 of the can transport 10 align with the relevant spinning station 10. The can offset means 7 is moved along the beam 23, to the can offset 7 of the newly introduced To feed flat can 44. By moving the can transport 7 towards the spinning station 10, this full flat can 44 then moved to the operating position.

The can transport means 2 can now be another selected one Spinning station 10 are delivered, where the procedure is repeated the empty compartment 201 of the Can transport means 2 no longer in the original place, but instead of the last one delivered to the machine full flat can 44. By repeating this process the empty compartment 201 is gradually moved until all full flat cans 44 introduced into the open-end spinning machine 1 have been replaced by empty (or at least exchangeable) Flat cans 44 have been replaced. The Can transport means 2 is then moved back to route 30.

The can-receiving part 20 of the can transport means 2 does not need rigidly with the end parts 21, 22 of the can transport means 2 to be connected. As in Figure 3 by double arrows 25 indicated, the part 20 can also opposite the end parts 21, 22 height adjustable to the flat cans 44 equal in height from part 20 to their loading or unloading position on the line 30 or the open-end spinning machine 1 or another textile machine or device - and of course also in the opposite direction - to be able to move.

The can transport means 2 can be different in principle be trained, e.g. as a gondola attached to a railroad (not shown) is movable. However, it is preferably as Ground vehicle designed that on rails or also without rails is movable.

Figures 4 and 11 show a designed as a ground vehicle Can transport means 26, which differs from that designed in the figure Can transport means 2 is formed.

The can transport means 26 according to FIGS. 4 and 11 carries one can receiving portion 260 and two end portions 261 and 262. The can-receiving part 260 has only two in total Pitches 263 and 269, and a pitches 269, usually by a jug 43 or 44 (full or empty) is occupied, as well as a second can parking space 263 (dashed), which can hold a jug 43 or 44 (full or empty) is kept free. The two end parts 261, 262 are provided with wheels 24, of which at least one set is steerable is. Both wheel sets are preferably steerable, so that the can transport means 26 in both directions also transversely to the longitudinal axis the cans 43 or 44 can be moved. The end parts 261 and 262 contain electric drives (in the Figures 4 and 11 shown). Furthermore, each end part 261 or 262 can offset means 70 and 700, which are only schematic in FIG are shown, but below in connection with 18 to 21 are described in more detail. The two (Partial) can offset means 70 and 700 are successively in the Distance of the width of a pitcher 263, 269 arranged and in two movable across the path of the can transport means 26 Movable levels. Both (partial) can offset means 70 and 700 can also be controlled independently of one another, as from the the description below.

The can transport means 26 is for executing driving orders constructed, the can transport means the route 30 (see Figures 1 and 2) with a single full can 43 or 44 leaves and a predetermined path 901 to a predetermined one Spinning station 10 follows. On arrival at the Spinning station 10 at which the can exchange is to be carried out is one can slot 263 is empty while the other can slot 269 filled with a full can 43 or 44 is. The can replacement by the can offset means 700 takes place now by first an empty jug 43 or 44 from the one in question Spinning station 10 (see FIG. 3) with the help of the can offset means 700 (Figure 11) on the can pitch 263 of the can transport 26 loaded, then this by one Spinning station division is continued and then the full can 43 or 44 from the can position 269 of the can transport 26 to the vacant position below the Spinning station 10 is brought (see Figures 12 and 13), so that on the can transport means 26 now the can parking space 269 becomes free. The pitcher space below the Spinning station 10 is thus a can delivery and at the same time a can delivery point.

After the can has been changed, the can transport means moves 26 back to route 30 to the empty jug taken Exchange 43 or 44 for a new full jug 43 or 44 and then get the next job. The Vehicle control is with enough intelligence (computing capacity) provided in order to be able to execute a motion task without further information or communication with a host computer to require so that a continuous communication link between the host computer and the can transport not applicable.

The can offset means 700 is now shown with the aid of FIGS to 21 described in detail. Figure 18 shows one Top view of such a can offset means 700 together with the end pieces 443 of two flat cans 44.

Each end piece 443 of a flat cans 44 is each with two tabs 444 and each provided with an attachment designed as a support bracket 445, to cooperate with the can offset means 700 serves as will be described in more detail below. Here it is assumed that the can transport means 26 (FIG. 11) with the can offset means 700 (similar to FIG. 12) a predetermined spinning station 10 for exchanging flat cans 44 is positioned.

As already explained with the aid of FIGS. 4 and 11, the can transport means 26 two pitches 263 and 269. For each can pitch 263 or 269 is on the can transport 26 a separate can offset means 70 or 700 is provided, as indicated in FIG. 11 is so that the loading and unloading of the can transport 26 is carried out.

The two can offset means 70 and 700 are mirror images of one another arranged. With the help of Figures 18 to 20 only the can offset means 700 is described below, because the structure and function of its parts are exactly the same as the can offset 70 correspond.

At the end part 262 of the can transport means 26, of which in Figure 18 shows only a part and which is shown in the Embodiment "skeletal" in lightweight construction is put together, are at different heights two rails 264 and 265, on which in a manner not shown a carrying carriage 73 is slidably mounted. With the two Ends this transverse to the longitudinal extent of the can transport 26 movable carriage 73 is one end of each Timing belt 732 connected, which is dashed in Figure 19 is indicated by the fasteners 738. As a drive a motor 266, e.g. a stepper motor the just like another engine 267 - which also as Stepper motor can be designed and its task later will be explained - on a plate 268 of the end part 262 is worn. The motor 266, of which only in Figure 19 a drive roller can be seen drives the toothed belt 732 on, the pulley 733, which also on the Plate 268 are attached, deflected and thus engaged with the drive roller of the motor 266 is held, by the two deflection wheels 733 a wrap of more than 180 ° is coming.

Depending on the direction of rotation of the motor 266, the carriage can thus 73 from one end of the guide rails 730, 731 to the other End and back, i.e. in one direction (see arrow X) or in the opposite direction (see arrow Y), across for the longitudinal extent and direction of travel of the can transport 26 are moved.

The can offset means 700 has a gripping means 72 and one trained as a carrier slider 74, the trolley (Slide) for moving back and forth on the sledge 73 is formed. Moved in one direction (arrow X) the can slide 74 towards the open-end spinning machine 1 (Figure 3) and in the other direction (arrow Y) from the machine path. The second motor 267 is provided for this movement, which drives an endless toothed belt 737, which with the help is deflected by deflection rollers 739 attached to the end part 262. The toothed belt 737 carries a driver 736, over which the Can slide 74 is connected to the toothed belt 737.

There are also two deflection rollers on the plate 268 for the toothed belt 737 739 provided for the toothed belt 737.

Motor 267 becomes motor 266 for movement in addition of the can slide 74 in the direction of one of the arrows X or Y driven, so that the can slide 74 a relative movement to the carriage 73. The can slide 74 can on both ends of the carriage 73 are moved, protrudes but this in none of its possible positions.

Because the sled 73 also compared to the Can transport means 2 is movable, this can be a certain Keep a distance from the open-end spinning machine 1 without that the exchange process is impaired. The illustrated Drives via the toothed belt 732, 737 enable the fixed Mount the drives on the end parts 261, 262 of the Can transport 2.

The carrying carriage 73 carries at different heights an upper and a lower guide rail 730 and 731, respectively which the can slide 74 with its base plate 740 in a more suitable manner Manner, e.g. with the help of castors, slidably mounted is. This base plate 710 carries a lifting device 721, e.g. is designed as a lifting cylinder, between two Bearing arms 741, which form a lifting column, through the Lifting device 721 vertically movable base plate 710 attached are.

The timing belt pulleys (not shown) of motors 266 and 267 penetrate the sled 73, giving freedom of movement of the carriage 73 in that it limits only can extend far out of the can transport means 26. This also applies to the slidable on the support carriage 73 mounted can slide 74, which carries a gripping means 72. The Cross-translational movements of the carriage 73 and can slide 74 are perfect due to the separate motors 266 and 267 independently of each other. However, in the event that the can slide 74 does not face the carrying carriage 73, the sled 73 but in relation to the can transport 26 should move, the drive of the can slide 74 compensate for the drive of the carrying carriage 73.

Both inductive and mechanical limit switches for the can slide 74 and the carriage 73 provided be.

The entire control of the can transport means 26 is on this housed itself.

The gripping means 72 has an L-shaped at its lower end Yoke 720 (Figure 20) and the lifting device already mentioned 721, which is attached to the can slide 71. The yoke is 720 connected to the lifting device 721 via a pivot axis 722, wherein a sliding guide 723 is provided to which the Gripping means 72 acting torques directly (instead of Lifting device 721) to be transferred to the can slide 74.

The yoke 720 is furthermore provided with two protrusions projecting upwards 724 provided, each with a groove 725 (Figure 19) exhibit.

If a can (e.g. flat cans 44) at the spinning station 10 The can transport is used for a full can to be exchanged 26 to the relevant spinning station 10 and stops there so that its empty can slot 263 is directly in front of the spinning station 10, where the can exchange should be made.

Carrier carriage 73 now moves on rails 264 and 265 across the can transport means 2 to out of the Can transport 2 out. On this sled 73 the can slide 74 travels transversely to the can transport means 2 out of the can transport means 2 at high speed until short in front of the jug and is lowered to the floor. The the last centimeter, the can slide 74 then moves slowly and pushes the can 44 slightly under the open-end spinning machine 1. Here the yoke 720 comes with its projections 724 under the support bracket 445 at the lower end of the to be replaced Flat can 44. This is the exact horizontal Positioning of the gripping means 72 ensured.

The gripping means 72 now moves upwards and lifts the jug slightly off. The support bracket 445 in the grooves 725 recorded, after which a slight raising of the yoke 720 for "Tilting" of the flat cans 44 around their illustrated in FIG. 18 End piece 442 (see Figure 5) leads, that is, the flat can 44 becomes easy to pick up on the can transport means 26 slanted.

The carrying carriage 73 and the can slide 74 are now withdrawn (to the right according to FIG. 18), and the flat can 44 is thereby pulled out of its position under the spinning station 10 and on the footprint 202 (can footprint 263 - see Figure 11) of the can-receiving part 260 of the Can transport 26 provided. The slight inclination the flat cans 44 when loading the can transport means 2 prevents a collision between the lower edge of the can and the edge of the can-receiving part 260 of the Can transport 26.

The carrying carriage 73 and the can slide 74 with the gripping means 72 drive so far into the can transport means 26, that the jug is finally central to the can transport 26 stands. Then the jug is lowered.

Now the can transport means 26 around a spinning division (= Distance from spinning station 10 to spinning station 10) - die is essentially the same as the distance between the pitches 263 and 269 of the can transport means 26 - and thus moved from the machine's can position to the can position, around the full can (flat can 44) in front of the Bring spinning station 10, at which the empty jug was previously removed has been. When subsequently unloading the full jug and with their delivery to the open-end spinning machine 1 with the help of the can offset means 70, the full can is not raised, but only pushed out of the can slide 74.

The tabs 444 and bracket 445 are at the bottom of the Flat cans 44 attached, while the gripping means 72 if possible runs close to the footprint 202.

The attachment on the jug, in the embodiment shown is designed as a bracket 445 and cooperation with serves the corresponding gripping means 72, can also be designed differently be, e.g. in the form of one or two cylindrical Projections or in the form of a rectangular block with a Recess on the underside etc.

The cans do not need any special under the spinning machine Can holder in vertical direction. The frame the open-end spinning machine 1 can, however, with side guides (see Figures 3 and 4) with some play to get one lateral tilting of the flat cans 44 during that described above Prevent movement.

Since the can (e.g. flat can 44) in the embodiment shown permanently pulled over the floor or is pushed, it is advantageous to wear-resistant sliding edges either at the jug or at the respective jug locations 263 and 269 to be provided. Are guides on the open-end spinning machine 1 provided (see Figures 3 and 4), are expediently also abrasion-resistant, e.g. made of polyethylene, educated. The same applies to other pitches outside the can transport means 26, i.e. not just at the Machine, but also in the can storage, too.

The can offset means 700 is in FIGS. 18 to 21 for the can exchange has been shown and described to the left. The same can offset agent can also be used to replace the can to the right or for optional can exchange to the right or to the left. In this case the carriage 73 is extended to the right, the movements of the can slide 74 and the already described Gripping means 72 can be executed. During the given one Can offset means 70 or 700 assigned can space The jug offset can still remain unoccupied 70 or 700 optionally for exchange on one or the other Side operated. But if the can offset agent 70 or 700 already a flat can 44 from the left (or from right) on the can transport means 2 must also to the same side, i.e. to the left (or to the right) one Flat can 44 are delivered.

The transfer of a flat cans 44 to the open-end spinning machine 1 is by moving the flat cans 44th from the footprint 202 in the direction transverse to the machine longitudinal plane executed. The parking space 202 in the can transport means 2 can be slightly higher than the footprint in the machine be. This small difference in height is when loading the Can transport means 2 by lifting the end piece 443 of the Flat cans 44 overcome by the lifting device 721.

Figure 21 shows the device shown in Figure 18 in its End position after the flat cans 44 on the can transport 26 has been brought. The transverse to the longitudinal extension of the can transport 26 slidable sled 73 has the task of gripping means 72 in the area of Bring the bracket 445 of the flat cans 44 without this the can transport means 26 its distance from that under the Spinning units 10 arranged flat can 44 must be changed. The actual train movement then takes place by moving of the sled-shaped can slide 74 on the sled 73, but also the carrying carriage 73 in its Home position returns.

To avoid excessive lifting movements for loading the can transport vehicle Avoiding 26 is as minor as possible Height difference between the pitches (pitches 263 and 269) of the can transport means 26 and the slivers 4 processing or processing machine and / or the pitches the can store 50, 51, i.e. the can delivery point 500 and the can delivery point 501. This should not exceed 100 mm, but even less and if possible not exceed 40 mm. If all the pitches on the can transport means 26 and outside it at the same horizontal level, is this for the can exchange or the can loading and -Unloading particularly advantageous.

The little or no height difference between the different ones Can space can be reduced by a small Distance A of the can receiving part 260 of the can transport means 26 from the floor (see FIG. 11) or through platforms 53 or 530 (see Figure 17) at the same height as the top of the can receiving part 260 of the can transport means 26 can be achieved.

In a system according to Figures 1 and 2 that runs Can transport means 2 directly between a spinning station 10 and route 30. To ensure that route 30 only perfect and perfectly filled cans 43 or 44 for Open-end spinning machine 1 or other machines, e.g. Spinning or twisting machines 11 or 110, the filled one Jug on its way between the spinning or twisting machine 11 or 110 and the route 30 or between the route 30 and the spinning or twisting machine 11 or 110, i.e. before sharing the pitchers to the machine, based on their physical condition there, i.e. with regard to any damage that the Tape processing can affect, and / or on checked their fill level.

The jug can be damaged for various reasons that their continued use in an automatic system is not is desirable. Such a jug can e.g. because of a Band break in operation also a considerable amount of Sliver included.

It is therefore advantageous to check the cans to make sure that there are no disruptions in continued use.

The check can of course be done by the operator, which, however, only with an automatic system Sampling can be done, but this is unsatisfactory is. It is therefore better if on the way of the can transport 2 or 26 a can testing station is arranged so that the cans are checked on the way. So it can Can transport means 2 itself with a can test station (not shown).

If such defects or errors are caused by an on the Can transport means 2 or 26 can testing station can be found, the jug can be in a suitable position repelled in the system by can transport means 2 and 26 a new jug is then added to maintain an optimal number of containers in the system. Suitable intermediate can storage devices can be used in the system for this purpose be provided as a buffer store, in which empty, full, to be checked or excreted cans stored become.

Examples of a can inspection station 6 are described below.

According to FIG. 15, the can testing station 6 is a can weighing device formed or has such a plate 65, which is interposed by a spring 650 supported on the ground. Depending on the filling level of the jug (e.g. flat jug 44) plate 65 is depressed, which is in a display device 651 is displayed. The pointer 652 of the display device 651 strokes according to the weight of the jug (e.g. Flat can 44) along a scale 653, which is in two partial scales 653a and 653b is divided. While the scale 653 from Pointer 652 is swept as long as the jug is your target weight, which it shows in its empty state scanned the 653b scale if this weight was due of ribbon residues in the can (e.g. flat can 44) exceeded becomes. In a manner not shown, the pointer 652 and the Partial scale 653b part of a circuit (see line 654) which a signal lamp 655 is connected.

On the plate 65, a rotary plate 66 is arranged, on which the jug by means of a schematically indicated gripping means728 can be turned off. The rotating plate 66 is more suitable Way in connection with a rotary drive 660, which the Can turn plate 66 in rotation.

A sensor 661 is also provided, which is suitable Way the top edge or any other relevant area of the Contour the cans (flat cans 44) can scan and if there is a deviation the signal lamp from a setpoint via a line 662 655 responds. For checking the can contour the rotary plate 66 is rotated by means of the rotary drive 660 transferred. If necessary, a lifting device can also be used be provided for the rotary plate 66 or the plate 65, so that each point of the can circumference is in the range of Sensor 661 can reach. Of course can - which is usually is easier to reach - sensor 661 can also be moved vertically be so that the mentioned lifting device for the rotary plate 66 or the plate 65 can be omitted.

The display device 651 thus serves to display a non-empty one Jug while sensor 661 responds when the physical condition the jug, in the embodiment shown the special important can edge, is not in order.

A different embodiment in which the Can testing station 6 is also designed as a can weighing device is shown in Figure 16. Here, the can 43 and 44 a loose, relative to the side walls of the jug and by action by means of a rod 67 from the outside vertically movable, i.e. liftable bottom 45. The jug stands up a pedestal 531, which has an opening 532 through which part of a rod 67 protrudes therethrough, which with protrudes into a coil 670 at its other end. The linkage 67 is part of a lifting device and is by a spring 671 so acted that the linkage 67 on the underside of the Bottom 45 of the can 44 rests and tries to lift it. Depending on the weight, one may be in the can 43 or 44 remaining sliver 4 succeeds more or less, so that the depth of penetration t is a measure of the weight of such Band restes is. According to the depth of penetration of the boom 67 in the coil 670 a signal is generated, for example a signal lamp (similar to 655 according to FIG. 15) for lighting up brings.

Such a floor 45 can be raised by the action of it from the outside also for the delay-free storage of a sliver 4 in the Can 43 or 44 by means of a filling head 31 and in the later distortion-free removal of the sliver 4 is an advantage.

As mentioned above, it goes without saying that the mentioned methods and devices not only between one or several routes 30, 30a, 36 or 36a and one or more Spinning or twisting machines 11, 11a, 110, 110a, 111, 111a 112, 112a or an open-end spinning machine 1 for use come or can be installed there, but also in context with other textile machines that release slivers - e.g. a carding machine also having a filling head - or process - e.g. a circular knitting machine, a ring or a Air spinning machine.
