Description

The present invention relates to a spinning machine having a plurality of side by side and on two sides of the machine located in the longitudinal direction of the spinning machine Kreuzspuleinrichtungen, each provided for winding yarn on sleeves, the Kreuzspuleinrichtungen are summarized a plurality of sections, with a plurality of sleeve magazines for storing empty Sleeves and with a arranged along a cross-winding device sleeve transport device for supplying the Kreuzspuleinrichtungen with empty tubes from the sleeve magazine and a method for operating sleeve transport devices on a spinning machine.

Modern textile machines, such as open-end rotor spinning or winding machines are able to wind different yarns on their many jobs on spools. For the individual different yarns, it is often necessary or at least helpful for later recognition of the respective yarn when different types of sleeves are provided on the textile machine. In this case, a type of yarn is wound on a specific sleeve, which is characterized in particular color.

From the DE 39 08 462 A1 is a spinning machine with a plurality of juxtaposed spinning stations, each provided with winding devices for winding cheeses known. Between the spinning stations and a sleeve loading station movable bobbin changer are arranged, each carrying a magazine for empty tubes with it. On each side of the machine there are two bobbin changers, each bobbin changer operating one machine half each.

The disadvantage here, however, that sleeves from a magazine can not be transported over the entire length. The provision of the different types of sleeves must therefore be done in each magazine, which is very expensive.

Object of the present invention is thus to provide a spinning machine, which is able to store different types of sleeves in a magazine and to be able to transport as needed to a corresponding job with the shortest possible transport time.

The object is achieved with a spinning machine with the features of the independent claims.

The spinning machine according to the invention has a plurality of cross-winding devices arranged side by side and on two machine sides located in the longitudinal direction of the spinning machine, which are each provided for winding yarn on sleeves. The Kreuzspuleinrichtungen are summarized in a variety of sections. In each section, for example, 8 or 10 cross-winding devices are arranged on each side of the machine. The spinning machine also has one or more sleeve magazines, which serve for the storage of empty tubes. A sleeve transport device arranged along the cross-winding devices serves to supply the cross-winding devices with empty tubes from the tube magazine.

According to the invention, several sleeve magazines are arranged on each machine side, and each sleeve magazine is assigned its own stationary sleeve transport device. The entire double-sided machine thus has at least four sleeve magazines in which the sleeves are stored. Different sleeve types can be stored in the sleeve magazines, with a suitable sleeve removed from the magazine and the stationary sleeve transport device as required is handed over. The stationary tube transporting device then conveys the corresponding sleeve to the cheese winding device on which the sleeve is required or, with appropriate equipment of the machine, also into an intermediate magazine which is provided at a location on the machine side.

The stationary tube transport device has the advantage that it is easy to use and control. It may be a conveyor belt on which the sleeve to be transported is placed or a transport chain, optionally with trays or hooks, with which the sleeve is transported to the requesting job or the intermediate magazine. The stationary arrangement avoids complex drive control of a movable bobbin changer for transporting the sleeves. The bobbin changer can perform its more demanding operation of changing the full bobbin with the empty bobbin faster, thus increasing the productivity of the machine. The supply of the correct sleeve at the corresponding cheese winding or job can be done with the stationary tube transport device within a very short time.

By appropriate, known devices such as grippers on the Kreuzspuleinrichtungen or jobs or latches the sleeves are removed from the tube transport device. If an individual sleeve store is provided on each cheese winding device, then the corresponding sleeve is removed directly from the individual sleeve store by the associated cheese winding device, provided that this cross winding device requires the corresponding type of sleeve. Otherwise, the sleeve is removed from the sleeve magazine, as described above, placed on the sleeve transport device and brought to the winding unit, where it is needed. If a multiple sleeve storage is provided, different sleeves are temporarily stored therein. These can either be of the same type, so that in several multi-sleeve storage, the are distributed along the machine, the appropriate sleeves are available. It can be kept sorted in the sleeves and placed on the transport device when the corresponding sleeve is needed. It is also possible that in the multi-sleeve memory a plurality of different types of sleeves are stored, which are selected in a corresponding need and placed on the sleeve transport device.

Preferably, each sleeve magazine is assigned exclusively to a predetermined machine side for storing empty sleeves for this machine side. Thus, the execution of the tube transporting device is particularly easy, since this needs to run only in a straight line and the sleeve does not have to be spent on the other side of the machine. Since in many cases the different types of sleeves will be subdivided according to the machine sides, the placement of the sleeve magazines can often be carried out in a simple way sorted. In addition, the sleeve magazines can store the sleeves but also chaotically and transport the respective type of sleeve to the job with an appropriate selection system.

It is particularly advantageous if the tube transport device is a conveyor belt arranged stationary along the cross-winding devices. The conveyor belt is inexpensive to manufacture and a proven sleeve transport. In particular, for the straight-line transport of the sleeves, it is very good.

If the sleeve transport device, in particular the conveyor belt, can be reversibly driven in an advantageous manner, then sleeves can be transported from the sleeve magazine or also from an intermediate store in both directions. This further increases the flexibility of the system. Accordingly, the request for a corresponding sleeve may be made such that it is sent from the sleeve magazine closest to the requesting work site. It is also possible that the sleeve at a sorted storage in the magazines is sent from the magazine having the requested type of sleeve. Due to the reversible operation, the beginning of the transport of a sleeve with the first tube transport device and a continuation of the transport of the sleeve with the second tube transport device can take place.

In a preferred embodiment of the invention, the tube transport devices of each machine side are parallel next to or above each other. The handling of the sleeves for placement on the tube transport device or for removal of the tube transport device is thus particularly easy to implement, regardless of whether the sleeve is to be transported with one or the other sleeve transport device.

If the sleeve transport devices assigned to the individual sleeve magazines are preferably arranged along only one part, in particular half, of the cross-winding devices on one side of the machine and supplement each other up to the entirety of the cross-winding devices on one side of the machine, the entire machine side is supplied with sleeves by the individual tube transport devices. The split in the longitudinal direction of the machine is cheaper to produce than two parallel sleeve transport devices.

Advantageously, the plurality of sleeve magazines are aligned parallel to the machine side. This facilitates the handling and loading of the sleeves from the sleeve magazine. In addition, the space of the machine is reduced and the assignment of the individual sleeve magazines to the individual sides of the machine is facilitated. Overall, this increases the capacity of the sleeve magazines, as they nestle along the machine side of the machine and thus several sleeve magazines can be provided.

If, in an advantageous embodiment of the invention, several sleeve magazines are arranged next to one another on each side of the machine, the capacity of the sleeves provided is thereby significantly increased in relation to an end-side arrangement of the sleeve magazines. It can be magazined so much more sleeves. The mostly manually performed populating the sleeve magazines with sleeves can thus be carried out very efficiently, since due to the high capacity rarely a re-fitting process must take place.

Preferably, the plurality of sleeve magazines are arranged in the region of supply units of the spinning machine, in particular on the drive frame, intermediate frame or end frame of the respective machine side. Thus, the sleeve magazines can be distributed along the machine and cause a total shortening of the feeding length of the spinning machine.

If, in an advantageous embodiment, the sleeve magazine has a transfer station for transferring a sleeve to the tube transport device, the tube transport device can very easily take over sleeves from the tube magazine and convey them to the corresponding sleeve stores or jobs.

Advantageously, the sleeve storage is provided with a receiving and / or dispensing device to receive the tubes from or on the sleeve transport device or can deliver. The sleeve transport device can thus be kept free for the transport of other sleeves and is not blocked by the cached sleeves in the sleeve stores.

A method according to the invention is used to operate sleeve transport devices on a spinning machine as described above and a plurality of side by side and two in the longitudinal direction of the spinning machine located on the machine side arranged Kreuzspuleinrichtungen, where each yarn is wound on sleeves has. The sleeve transport devices can be reversibly driven. The sleeve transport devices associated with the individual sleeve magazines are arranged along a part, in particular half, of the cross-winding devices of a machine side and supplement each other up to the entirety of the cross-winding devices of a machine side. A first sleeve transport device is driven in the direction away from the first sleeve magazine assigned to it, in order to supply the first cross-winding devices associated with it with sleeves from the first sleeve magazine. A second, the first sleeve transport device adjacent and other, second Kreuzspuleinrichtungen associated with the tube transport device is driven towards the associated second sleeve magazine. This makes it possible to supply the second cross-winding devices with sleeves from the first sleeve magazine.

By a corresponding reversal of the transport, it is thus also made possible that the sleeve from the second sleeve magazine first placed on the second sleeve transport device and promoted to the beginning of the first tube transport device and taken over there by the first tube transport device and further promoted. The two only one part of the textile machine covering the sleeve transport devices are thus able to transport sleeves from both the one and the other magazine to each of the cross-winding devices or jobs.

Preferably, the sleeve transported with the first sleeve transport device is transferred to the adjacent second sleeve transport device and transported further in the transport direction of the first tube transport device. A fast transport along all Kreuzspuleinrichtungen is possible. The transfer, for example, by an appropriate coordinated drive control of the two tube transport devices done.

The device according to the invention and the method are designed according to the preceding description, wherein said features may be present individually or in any desired combination.

In the following description of the illustrated alternative embodiments, the same reference numerals are used for features that are identical and / or at least comparable compared to the other embodiments shown in their design and / or mode of action. Unless these are explained in detail again, their design and / or mode of action corresponds to the design and mode of action of the features already described above.

In FIG. 1 is a plan view of a spinning machine 1 shown outlined, for example, an open-end rotor spinning machine or a winder, shown. The spinning machine 1 has a drive frame 2 and a final frame 3, which are respectively arranged at the end of the spinning machine 1. The spinning machine 1 has two machine sides in the longitudinal direction, on which a plurality of cross-winding devices 4 between the drive frame 2 and the end frame 3 are arranged. For reasons of clarity, only one of the cheese winding 4 is provided with a reference numeral. The plurality of cross-winding devices 4 is summarized in sections 5.1 to 5.5. In each section 5.1 to 5.5 eight Kreuzspuleinrichtungen 4 are arranged on each side of the machine. In each of the cheese winding 4 an unillustrated holder is provided for a sleeve on which a yarn is wound crosswise. Depending on the type of yarn, a different type of sleeve is required. This is necessary or at least helpful in order to be able to identify the type of yarn which is located on the sleeve again later when the coil is no longer located on the cross-winding device 4.

Along the multiplicity of cross-winding devices 4, two sleeve transport devices 6.1, 6.2 and 6.3, 6.4 are arranged on each side of the spinning machine 1. The sleeve transport devices 6.1 to 6.4 are each formed in the present embodiment as a conveyor belt on which sleeves are placed and transported to a predetermined destination. The sleeves are in large numbers in several sleeve magazines 7.1 to 7.4. In the embodiment of FIG. 1 are in the end frame 3 on each side of the machine two sleeve magazines 7.1 and 7.2 or 7.3 and 7.4 arranged. The two sleeve magazines 7.1 and 7.2 or 7.3 and 7.4 are arranged one behind the other in the machine longitudinal direction. As a result, they nestle closely to the spinning machine 1 and thus require little space. By dividing on each side of the machine in two sleeve magazines 7.1 and 7.2 or 7.3 and 7.4, the plant even more flexible. It is a sorted magazine of the sleeves possible, so that, for example, four different types of sleeves can be magaziniert by these four existing sleeve magazines 7.1 to 7.4. The transmission of the sleeves to the corresponding cheese winding 4 can be very simple control technology, since it is known which type of sleeve is in which of the sleeve magazines 7.1 to 7.4.

The sleeve transport devices 6.1 to 6.4 in the present embodiment have a single transport direction in the arrow direction. This means that the sleeves are removed from the sleeve magazines 7.1 to 7.4, transferred to the sleeve transport device 6 and moved by this in the direction of the arrow.

Each of the tube transport devices 6.1 to 6.4 extends along all cross-winding devices 4 or sections 5.1 to 5.5 and is associated with a specific sleeve magazine 7.1 to 7.4. Each sleeve, which is arranged in one of the sleeve magazines 7.1 to 7.4, can thus be fed to any workstation or cross winding station 4 on its machine side.

Depending on the type of yarn on the corresponding cheese winding 4 a type of sleeve is requested. The control of the tube transporting devices 6.1 to 6.4 is designed such that from the sleeve magazine 7.1 to 7.4, in which the requested type of sleeve is located, the sleeve is placed on the tube transport device 6.

The presentation of the FIG. 2 also shows a spinning machine 1 in plan view and in sketched representation. It corresponds essentially to the arrangement of the spinning machine 1 of FIG. 1 , The difference here is that the sleeve magazine 7.1 to 7.4 are distributed to the drive frame 2 and the end frame 3. The sleeve supply thus takes place from both ends of the spinning machine 1. Again, each of the sleeve transport devices 6.1 to 6.4 extends along all cross-winding devices 4 a machine side. The two sleeve transport devices 6.1 and 6.2 or 6.3 and 6.4 run parallel to each other. They are here next to each other, ie horizontally to each other. Alternatively, however, they can also be arranged one above the other, ie vertically relative to one another. As with FIG. 1 each cross-winding unit of two tube transport devices 6.1 and 6.2 or 6.3 and 6.4 from with sleeves can be loaded. With a sorted storage of the sleeves in the sleeve magazines 7.1 to 7.4 two different yarns can be wound on each side of the machine. Of course, it is also possible that several types of sleeves are stored in a sleeve magazine 7.1 to 7.4 and thus much more different yarns can be wound. In the individual sleeve magazines 7.1 to 7.4 then the selection of the required sleeve must be done.

The cross-winding device 4 is supplied by the sleeve magazines 7.1, 7.2 or 7.3, 7.4 arranged on the drive frame 2 and the end frame 3. If the machine is to be very long, it may be useful to have one or more sleeve storage devices, not shown, in which the sleeves can be intermediately stored before they are needed at the package winding station 4. Thus, the delivery of the sleeve to the cheese package 4 can be done even faster. Such buffers can also be used in the other embodiments of the invention.

FIG. 3 shows a spinning machine 1, which is constructed similar to the spinning machine 1 of FIG. 2 , Different is in the execution according to FIG. 3 the arrangement of the tube transport devices 6.1 and 6.2 or 6.3 and 6.4. Two of the sleeve magazines 7.1, 7.3 are arranged on the end frame 3 of the spinning machine 1, while the other two sleeve magazines 7.2, 7.4 are arranged on the drive frame 2. The sleeve transport devices 6.1 and 6.2 or 6.3 and 6.4 extend only over half of each side of the machine. Each sleeve transport device 6.1 and 6.2 or 6.3 and 6.4 is assigned to one of the sleeve magazines 7.1, 7.2 or 7.3, 7.4 and one side of the machine.

It can be provided that the sleeve transport device 6.1 to 6.4 can transport in only one direction. In this case, supplies each sleeve magazine 7.1 to 7.4 only a quarter of the machine with sleeves. In another embodiment, however, it can also be provided that each sleeve transport device 6.1 to 6.4 can transport sleeves in both directions. In this case, the control of the tube transport device 6.1 to 6.4 can be carried out such that they are operated concurrently and thus a transfer of the sleeve from one sleeve transport device 6.1, 6.3 can take place on the other sleeve transport device 6.2, 6.4 and vice versa. When the tube transporting devices 6.1 to 6.4 are operated in this way, all cross-winding stations 4 on one side of the machine can be supplied with sleeves by both sleeve magazines 7.1, 7.2 and 7.3, 7.4. Accordingly, the transport direction of the tube transport device 6 is indicated by arrows pointing in both directions. Thus, on the one hand, a sleeve can be transported from the sleeve magazine 7.1 in the direction of the sleeve magazine 7.2 and on the other hand, a sleeve from the sleeve magazine 7.2 in the direction of the sleeve magazine 7.1. The same applies analogously to the opposite machine side.

This arrangement can be cheaper in terms of space requirements and also allows more sleeve magazines, similar to in FIG. 1 and FIG. 2 shown to be arranged on the spinning machine 1 following the respective sleeve magazine. Thus, the capacity of magazineable sleeves was even more expandable.

By connecting the sleeve magazines 7.1, 7.3 or 7.2, 7.4 or by a corresponding device which moves sleeves on the other side of the machine, the sleeve magazines 7.1 to 7.4 can also provide a sleeve supply both sides of the machine. This is in FIG. 4 shown. There is a spinning machine according to FIG. 3 which has a transfer device 8 at each machine end. With the transfer device 8 sleeves can be conveyed from one side of the machine to the other side of the machine, as indicated by the double arrow. However, the transfer device can also be arranged in the middle of the spinning machine, where the sleeve transport devices 6.1 to 6.4 ends. Similarly, such a transfer device 8 in other embodiments of the invention, such as those of FIGS. 1 or 2 possible. The transfer device 8 can also be done simply by a deflection of the tube transport devices 6.1 to 6.4, so that the sleeves are thus promoted to the other side.

The present invention is not limited to the illustrated and described embodiments. Variations within the scope of the claims are also possible as a combination of features, even if they are shown and described in different embodiments.
