Description

[0026] Further advantages of the invention are described in the following embodiments. The following is shown:

[0027] FIG. 1 a spinning-mill machine with a multiple number of sleeve stacks at one machine end and one circumferential sleeve transport device per machine,

[0028] FIG. 2 a spinning-mill machine with a multiple number of sleeve stacks at both machine ends and one circumferential sleeve transport device per machine,

[0029] FIG. 3 a spinning-mill machine with a multiple number of sleeve stacks at one machine end and, in each case, one sleeve transport device per machine side,

[0030] FIG. 4 a spinning-mill machine with a multiple number of sleeve stacks at one machine end and, in each case, one sleeve transport device per machine side, with a centrally arranged common entraining element and

[0031] FIG. 5 a transport carriage with a sleeve.

[0032] With the following description of the illustrated alternative embodiments, the same reference signs are used for characteristics that are identical and/or at least comparable in their arrangement and/or mode of action compared to the other illustrated embodiments. To the extent that such are not described once again in detail, their designs and/or modes of action correspond to the designs and modes of action of the characteristics described above.

[0033] FIG. 1 shows a top view of a spinning-mill machine 1 shown in outline, for example an open-end rotor spinning-mill machine or a winding machine. The spinning-mill machine 1 features a drive frame 2 and an end frame 3, which are respectively arranged at the end of the spinning-mill machine 1. The spinning-mill machine 1 features two machine sides in the longitudinal direction, on which a multiple number of cross-winding devices 4 are arranged between the drive frame 2 and the end frame 3. For reasons of clarity, only one of the cross-winding devices 4 is provided with a reference sign. The multiple number of cross-winding devices 4 is collected into sections 5.1 to 5.5. In each section 5.1 to 5.5, eight cross-winding devices 4 are arranged on each machine side. In each of the cross-winding devices 4, a holder (not shown here) for a sleeve 9 is provided, on which a yarn is wound cross-wise. Depending on the yarn type, a different sleeve type is required. This is necessary or at least helpful in order to, later on, be able to more easily identify the yarn type that is located on the sleeve 9, if the bobbin is no longer located on the cross-winding unit 4.

[0034] In the present embodiment, a sleeve transport device 6 is formed as a conveyor belt, on which transport carriages 8 are located, placed on the sleeves 9 and transported to a predetermined destination. The conveyor belt of the sleeve transport device 6 surrounds the machine 1, and thus can reach all of the cross-winding devices 4 and sleeve stacks 7.1 to 7.4. The sleeves 9 are initially located in a large number in a multiple number of sleeve stacks 7.1 to 7.4. In the embodiment of FIG. 1, two sleeve stacks 7.1 and 7.2 or 7.3 and 7.4, as the case may be, are arranged in the end frame 3 on each machine side. The two sleeve stacks 7.1 and 7.2 or 7.3 and 7.4, as the case may be, are arranged one behind the other in the direction of the machine. As a result, they cling closely to the spinning-mill machine 1, and thus require little installation space. However, they can also be arranged elsewhere in the end frame 3, for example on the front side or on the front side and the longitudinal sides of the end frame 3. In the sleeve stacks 7.1 and 7.2 or 7.3 and 7.4, as the case may be, a sorted stacking of the sleeves 9 takes place, such that, by such four existing sleeve stacks 7.1 to 7.4 (for example), four different sleeve types can be stacked. In terms of control technology, the transmission of the sleeves 9 to the corresponding cross-winding devices 4 can take place very easily, since the sleeve type in which the sleeve stacks 7.1 to 7.4 is located is known.

[0035] To send the sleeves 9, a specified sleeve type from the sleeve stack 7.1 to 7.4, in which the corresponding sleeve 9 is stacked, is placed on a carriage 8. The conveyor belt of the sleeve transport device 6 begins to move, and thus conveys the carriage 8 to the desired cross-winding station 4. Alternatively, with a constantly moving conveyor belt, a stopping device can bring the carriage 8 to a halt at the corresponding sleeve stack 7.1 to 7.4 and the desired cross-winding station 4.

[0036] FIG. 2 shows a spinning-mill machine 1, which has a similar construction to the spinning-mill machine 1 of FIG. 1. With the design of FIG. 2, the arrangement of the sleeve stacks 7.1 to 7.4 varies. Two of the sleeve stacks 7.1, 7.3 are arranged on the end frame 3 of the spinning-mill machine 1, while the other two sleeve stacks 7.2, 7.4 are arranged on the drive frame 2. The sleeve transport device 6 in turn extends around the entire machine 1 and passes through a cross-winding station 4 and each of the sleeve stacks 7.1 to 7.4 and thus both machine sides. The distribution of the sleeve stacks 7.1 to 7.4 on the drive frame 2 and the end frame 3 can be advantageous in terms of space utilization on the machine 1. The carriages 8 (not shown), just like in FIG. 1, move to a conveyor belt of the sleeve transport device 6.

[0037] It can be provided that the sleeve transport device 6 can transport the sleeves 9 only in one direction. However, in another design, it can also be provided that the sleeve transport device 6, as indicated by the arrows in both directions, can transport sleeves 9 in both directions. In this case, the control device of the sleeve transport device 6 can determine how the supply of the required sleeve 9 can be done most rapidly, and accordingly determine the direction of transport. Thus, on the one hand, a sleeve 9 can be transported from the sleeve stack 7.1 in the direction of the sleeve stack 7.2 and, on the other hand, a sleeve 9 can be transported from the sleeve stack 7.2 in the direction of the sleeve stack 7.1. The same applies to the opposite machine side by analogy.

[0038] This arrangement can be more favorable in terms of space requirements and allows additional sleeve stacks 7.1 to 7.4, similar to those shown in FIG. 1, to be arranged on the spinning-mill machine 1 following the respective sleeve stack. Thus, the capacity of the stackable sleeves 9 was even more expandable.

[0039] In FIG. 3, a sleeve transport device 6.1 or 6.2, as the case may be, is arranged along the multiple number of cross-winding devices 4 on each side of the spinning-mill machine 1. In the present embodiment, each of the sleeve transport devices 6.1 and 6.2 is formed as a conveyor belt, on which transport carriages 8 are located, placed on the sleeves 9 and transported to a predetermined destination. The sleeves 9 are initially located in a large number in a multiple number of sleeve stacks 7.1 to 7.4. In the embodiment of FIG. 3, two sleeve stacks 7.1 and 7.2 or 7.3 and 7.4, as the case may be, are arranged in the end frame 3 on each machine side. The two sleeve stacks 7.1 and 7.2 or 7.3 and 7.4, as the case may be, are arranged one behind the other in the direction of the machine. Due to the division on each machine side into two sleeve stacks 7.1 and 7.2 or 7.3 and 7.4, as the case may be, the system is even more flexible. A sorted stacking of the sleeves 9 is possible, such that, by such four existing sleeve stacks 7.1 to 7.4 (for example), four different sleeve types can be stacked.

[0040] In the present embodiment, the sleeve transport devices 6.1 and 6.2 have a single direction of transport in the direction of the arrow. This means that the sleeves 9 are removed from the sleeve stacks 7.1 to 7.4, transferred to the sleeve transport device 6 or the carriages 8 and moved in the direction of the arrow.

[0041] Each of the sleeve transport devices 6.1 and 6.2 extends along all of the cross-winding devices 4 or sections 5.1 to 5.5, as the case may be, of a machine side and returns, in the machine center, back to the sleeve stack 7.1 and 7.2 or 7.3 and 7.4, as the case may be. Thus, each sleeve 9, which is arranged in one of the sleeve stacks 7.1 to 7.4, can be supplied to any work station or cross-winding station 4, as the case may be, on its machine side.

[0042] FIG. 4 shows a spinning-mill machine 1 with a multiple number of sleeve stacks 7.1 to 7.4 at one machine end, in this case the end frame 3, and in each case a sleeve transport device 6.1, 6.2 per machine side, with a centrally arranged common entraining element. The entraining element is once again a conveyor belt, on which the carriages 8 are arranged. The centrally arranged common entraining element serves both sleeve transport devices 6.1 and 6.2 for the return transport of the empty carriages 8. However, carriages 8 loaded with sleeves 9 can also be conveyed in this middle track section. By means of a switch 12, the carriages 8 are guided by or on the sleeve transport device 6.1, 6.2. Thereby, the carriages 8 can be directed to the sleeve transport device 6.1 or 6.2 on which they are currently needed. This design has the advantage that sleeves 9 can be conveyed out of each of the sleeve stacks 7.1 to 7.4 to each machine side. Thus, each side can access each stored sleeve type.

[0043] Depending on the yarn type on the corresponding cross-winding device 4, a sleeve type is requested. The control of the sleeve transport devices 6.1 and 6.2 is designed in such a manner that the sleeve 9 is placed on the sleeve transport device 6 and the carriage 8 from the sleeve stack 7.1 to 7.4 in which the requested sleeve type is located.

[0044] FIG. 5 shows a transport carriage 8 in a perspective view. The carriage 8 has a flat bottom plate, with which it rests on the conveyor belt of the sleeve transport devices 6 or 6.1 and 6.2, as the case may be, and can be taken from the moving conveyor belt. On the bottom plate, the sleeve 9 is held in guides 10. The guides 10 ensure the secure reception of the sleeve 9, so that they cannot fall from the carriage 8 during transport. On the other hand, the guides 10 also enable the sleeve 9 to be easily place, for example with gripper, on the carriage 8, and once again removed. The bottom plate has tapered end pieces, so that the carriage 8 can be conveyed through the curves of the sleeve transport devices 6 and 6.1 and 6.2, easily and without entanglement. In addition, the carriage 8 features a bar code 11, with which it is uniquely identifiable. Thus, the carriage 8 can be linked with its data to a sleeve 9 via a control device. Thus, a clear allocation of a specific sleeve type to the carriage 8, and thus to the location of the sleeve 9 or the carriage 9, as the case may be, is also possible.

[0045] At each of the sleeve stacks 7.1 to 7.4, a detection device is provided; this detects the type of the sleeve 9. If the sleeve 9 is transferred from the sleeve stack 7.1 to 7.4 to a transfer station at the transport carriage 8, the sleeve type 9 is linked to the identifier of the transport carriage 8. In the control device, with a type of writing device (in a manner of speaking), the entrained sleeve 9 is described with the number of the transport carriage 8, and thus can be detected at any time, for example by scanners arranged on the sleeve transport devices 6 and 6.1 and 6.2.

[0046] This invention is not limited to the illustrated and described embodiments. Variations within the scope of the claims, just as the combination of characteristics, are possible, even if they are illustrated and described in different embodiments.
