The invention relates to a device of the im Preamble of the first claim specified type.

It is known to use cans when filing fiber tows

use. Such a method for filing a fiber?

kabeis in a jug results e.g. from the DT-OS I.

24 27 722.. '

It is also known to let these systems work automatically. The problem arises that the Kannenwech- \

the endlessly delivered fiber cable is also automatic | must be cut off at the full jug. |

There are already a number of solutions to this problem area §

known. For example, in DT-OS 16 85 580 a |

Device described in which when fully filled f

A storage board can be pushed into the grain. \ One edge of this storage board also serves as a cutting ^

furnishings. The I received during the can change process

Fiber cable is collected on this shelf. Is |

an empty can inserted in place of the full, the \ shelf board is pushed out of the grain, and

the now accumulated on the shelf board fiber cable '· fall together into the pot.

The disadvantage of this device is that the severed cable end falls into the full storage can, so that it is only very hard to find again. Another Kachteil the device is that when stripping the on the shelf collected material entanglements can occur which later form knots when the cable is pulled out of the jug can lead in the wiring harness.

Furthermore, the DT-PS 10 91 010 is known in which the cable

Torn when handing over from one jug to the other will. However, these are cables that consist of short, relatively loosely connected fibers, in particular made of natural fibers. This process is impossible with fiber cables made of synthetic filaments.

The DT-AS 20 35 020 is also known. There are three jugs on a turntable. Between everyone k "anne is a roof-shaped body designed as a style organ Body provided. In the axis of rotation of the turntable there is a fixed arm with a cutting device arranged so that it does not obstruct the fiber optic cable route. During the can change, the rotation of the turntable, the fiber cable is placed over the roof-shaped body. Is the change process completed, i.e. the empty Kanne stands under the cable delivery device, so it lowers the cutting device on the roof-shaped body and sever the cable. Then the cutter is back raised, and the two free ends fall back into the respective cans.

Here, too, it is disadvantageous that the severed fiber cable falls back into the filled can. The other will be the same The end of the fiber cable is only released by lifting the boom into the can that has already been loaded, in the meantime Several layers have already been filled in, so that the free end subsequently falls in, which also occurs when pulling out the fiber cable from the jug can lead to difficulties. Furthermore, it is disadvantageous that the cans on a self-contained, circular arc-shaped path must be guided, otherwise the separating device can no longer work.

Furthermore, US Pat. No. 3,656,383 became known. It is from this known to arrange a horizontally movable separating device between the full and empty jug, the overhanging Pushes a piece of fiber to a separating point located outside the can track.

The disadvantage of this device can be seen in the fact that, due to the fact that it is arranged in a stationary manner outside of the can track Separation point the size and height of the can is limited. In addition, this device cannot be disconnected under voltage so that safe cutting of the cable is not guaranteed.

From this the object of the invention can be derived, a device for fiber cables made of synthetic threads to propose the type mentioned, which is independent of the type of can changing device few elements and can be arranged to save space.

To solve this problem, the features of the characterizing parts of the first claim are proposed. This achieves that the system is independent of the type of Kannev changing device works, i.e. it does not matter whether the cans are arranged on a turntable or from can be brought up in a straight line on a conveyor belt. This ensures that the piece of cable to be separated is always secure is separated. It is also advantageous that in this solution according to the invention the separating device consists of only a few There are machine parts, so that the costs and the control effort are very low.

Likewise, regardless of the position of the cable between the two cans, it is always guaranteed that what is to be cut through Cable piece comes to rest on the counter pressure plate. A safe and simple arrangement of the elements is achieved as a result. Another advantage of this design is that the cutting device is no longer above it in its rest position the edge of the can. This makes a very low one

'· Height reached.

\ The arrangement of the counter pressure plate means that it is significantly below

I The development according to claim 3 results in a further circuit-I technical simplification without endangering the direction of work.

^{f! Ä} the object is solved by claims 5 and 6, the fiber cable

I claim 7 solves the problem of making the jugs as space-saving as possible

§ supply and discharge. This type of can transport is harmonized

especially with the separating device according to the invention, however it is not so limited.

In the following the invention is described in more detail on the basis of a preferred exemplary embodiment with reference to the figures.
They represent:

These draw-in godets convey the fiber cable into a Xabelleit device, for example a rotatably mounted, spatially coiled trunk 7. Through this trunk, the straight fiber cable delivered is deflected onto a helical path f. Below the trunk 7 is a storage can 8 ^! into which the cable falls in free fall. The storage can 8 can either be round or angular, can be changed
or also be arranged in a fixed manner. The jugs are from a
schematically indicated transport device delivered from a ready position and - after filling -
transported to a pick-up station. :

In the transport direction 9, the separating device is behind the filling station 10 attached.

It consists of the guide rail 11, for example
designed as a double T-beam and attached to the ceiling of the workshop or a gallows, the cutting unit,
which is made up of the carriage guide 12, the carriage 13 and the counter-pressure plate 14, and the leading edges of the fiber cable
15th

The slide guide 12 is arranged hanging vertically and \

connected to a trolley 16, which in the guide bar

ne 11 is performed. The trolley is turned by a motor 17 \

driven. Instead of the guide rail 11 and the trolley ^l :

16 it is also possible to use cylinder-piston units. J

It makes sense here to keep the cylinders stationary and to the KoI- ϊ

ben or piston rods to arrange the slide guide 12. For )

the slide guide 12 can also be a cylinder-piston-> Unit, as it is for example under the name "ORIGA" in the trade, can be used (Fig. 3a).

On the horizontally movable slide guide 12 is the

7734175 08/03/78

Carriage 13, which carries the cutting edge (knife 1 8) or another suitable separating means, for example a heating wire, can be moved vertically up and down via a suitable drive device. Its rest position is shown in Fig. 1, 2 and 3 and corresponds to the uppermost position.

At the lower end of the slide guide 12, the counter-pressure plate 14 is fastened in the effective area of the knife 18. The counter pressure plate 14 is provided here substantially below the edge of the can.

A fiber cable guide device is also located on the slide guide 12 15 attached. In the direction of travel of the trolley 16, it has a downwardly sloping edge, whereby the lower edge must run at least to below the knife in the rest position. Your function is explained in detail further below.

In Fig. 3b is the holder of the fiber cable guide device visible, which consists of the two rods 21 attached to the counterpressure plate 14.

The following operating phase is assumed: a full can 8.1 is exchanged for an empty can 8 been. This exchange process is continuous and lossless. This creates a transition from the full jug to the empty one Fiber cable part hanging over the edge of the can. This fiber cable part must be separated in order to transport away the full can- For this, it is necessary that there is a gap between the jug and the jug 8.1, which is the width tier separator 10 corresponds. This can be done by an additional Forward movement of the full can 8.1, but also by delivering the cans at the distance already required.

The separating device 10 is in its rest position during the can change, i.e. it is to the rear (to the left in FIG Fig. 2) withdrawn from the can transport path.

Is the can change completely completed, i.e. the empty can 8 is already being loaded, so the separating device 10 moves between the two cans. The fiber cable guide facility 15 grasps the sagging piece of fiber cable during this retraction movement and pushes it due to its inclination in the direction of the counter-pressure plate 14. The separating device moves so far between the cans that in every case it is ensured that the cable comes into the working area of the knife 18.

The cable guide device 15 has the advantage that the rest position of the knife 18 may be below the edge of the can. Here, the leading edge 15 runs from just above the can edge up to the space between knife 18 and counter pressure plate 14. With this arrangement, a special Achieve low overall height of the entire separating device.

Then the carriage 13 is set in motion so that he is going downhill. As a result, the knife 18 takes the piece of cable lying below the fiber guide edge with it and cuts it at the Impact on the counter pressure plate 14.

If it is considered necessary that the cable be cut under tension, clamping jaws may be provided next to the knife will. A simple and effective type of clamping consists in arranging spring steel sheets 19 on the right and left next to the knife 18 on the carriage 13 and the training of the Projections or pedestals 20 on the counter pressure plate 14.

To make sure that the cut end of the cable is filled Kanne is easy to find again and not, in part, accidentally If it falls back into the filled jug, a further clamping plate 22 is arranged on the counter-pressure plate 14 intended. The clamping plate 22 is arranged on the side of the collection station in such a way that it forms a slot with the rod 21, into which the slide 13 is pushed to the counter pressure plate 14 Fiber piece can be inserted and clamped.

it cannot be ruled out that the overhanging cable end is pulled into the jug during the filling process, for example conceivable, on the other side of the counter pressure plate 14 also a clamping plate - similar to the one described above - to provide in which the thread is placed. Since the can is traversed and rotated, the end of the thread cannot stay in this clamping plate. It is therefore a suitable option, for example a slot against the direction of rotation the can on the edge of the can, in which the overhanging cable end is caught and thereby out of the clamping plate is pulled out at the separating device.

After the cutting process, the carriage 13 is raised again and the entire fiber cable cutting device 10 is removed from the can track pulled back to their original position. It stays there until the next pot is filled.
