DETAILED DESCRIPTION

(6) Reference will now be made to embodiments of the invention, one or more examples of which are shown in the drawings. Each embodiment is provided by way of explanation of the invention, and not as a limitation of the invention. For example features illustrated or described as part of one embodiment can be combined with another embodiment to yield still another embodiment. It is intended that the present invention include these and other modifications and variations to the embodiments described herein.

(7) 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.

(8) FIG. 1 shows a top view of a spinning-mill machine 1 shown in outline, for example an open-end rotor spinning 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, a specific number, such as 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 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, if the bobbin is no longer located on the cross-winding unit 4.

(9) Along the multiple number of cross-winding devices 4, two sleeve transport devices 6.1, 6.2 or 6.3, 6.4, as the case may be, are arranged on each side of the spinning-mill machine 1. In the present embodiment, each of the sleeve transport devices 6.1 to 6.4 is formed as a conveyor belt, on which sleeves are placed and transported to a predetermined destination. The sleeves are 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 longitudinal direction of the machine. As a result, they cling closely to the spinning-mill machine 1, and thus require little installation space. 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 is possible, 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 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.

(10) In the present embodiment, the sleeve transport devices 6.1 to 6.4 have a single direction of transport in the direction of the arrow. This means that the sleeves are removed from the sleeve stacks 7.1 to 7.4, transferred to the sleeve transport device 6 and moved by it in the direction of the arrow.

(11) Each of the sleeve transport devices 6.1 to 6.4 extends along all of the cross-winding devices 4 or sections 5.1 to 5.5, as the case may be, and is allocated to a specific sleeve stack 7.1 to 7.4. Thus, each sleeve, 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.

(12) Depending on the yarn type on the corresponding cross-winding device 4, a sleeve type is requested. The control device of the sleeve transport devices 6.1 to 6.4 is designed in such a manner that the sleeve is placed on the sleeve transport device 6 from the sleeve stack 7.1 to 7.4, in which the requested sleeve type is located.

(13) The illustration of FIG. 2 also shows a spinning-mill machine 1 in a top view and in a sketched illustration. It essentially corresponds to the arrangement of the spinning-mill machine 1 of FIG. 1. In this case, a difference is that the sleeve stacks 7.1 to 7.4 are distributed at the drive frame 2 and the end frame 3. Thus, the supply of sleeves takes place from both ends of the spinning-mill machine 1. In turn, each of the sleeve transport devices 6.1 to 6.4 extends along all of the cross-winding devices 4 of one machine side. The two sleeve transport devices 6.1 and 6.2 or 6.3 and 6.4, as the case may be, run parallel to each other. Here, they are next to each other; that is, they are shown horizontally relative to each other. Alternatively, they may be arranged one above the other; that is, vertically relative to each other. As in the case of FIG. 1, each cross-winding station can be loaded with sleeves by two sleeve transport devices 6.1 and 6.2 or 6.3 and 6.4, as the case may be. With a sorted storage of the sleeves in the sleeve stacks 7.1 to 7.4, two different yarns can be wound on each machine side. Of course, it is also possible that several sleeve types are stored in a sleeve stack 7.1 to 7.4, and thus significantly more different yarns can be wound. The selection of the required sleeve must then be made in the individual sleeve stacks 7.1 to 7.4.

(14) The cross-winding device 4 is supplied by the sleeve stacks 7.1, 7.2 or 7.3, 7.4, as the case may be, arranged on the drive frame 2 and the end frame 3. If the machine is very long, it may be useful that one or more sleeve storage devices (not shown), in which the sleeves can be stored on an intermediate basis, are arranged along the machine, before being required at the cross-winding station 4. Thus, the delivery of the sleeve to the cross-winding station 4 can be done even more rapidly. Such intermediate storage devices can also be used in the other embodiments of the invention.

(15) FIG. 3 shows a spinning-mill machine 1, which has a similar construction to the spinning-mill machine 1 of FIG. 2. With the design of FIG. 3, the arrangement of the sleeve transport devices 6.1 and 6.2 or 6.3 and 6.4, as the case may be, is varied. 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 devices 6.1 and 6.2 or 6.3 and 6.4, as the case may be, extend only over half of one machine side. Each sleeve transport device 6.1 and 6.2 or 6.3 and 6.4, as the case may be, is allocated to one of the sleeve stacks 7.1, 7.2 or 7.3, 7.4, as the case may be, and one machine side.

(16) It can be provided that the sleeve transport devices 6.1 to 6.4 can transport in only one direction. In this case, each sleeve stack 7.1 to 7.4 supplies only one quarter of the machine with sleeves. However, in another design, 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 sleeve transport devices 6.1 to 6.4 can take place in such a manner they are operated concurrently, and thus a transfer of the sleeve from one sleeve transport device 6.1, 6.3 to the other sleeve transport device 6.2, 6.4, and vice versa, can take place. If the sleeve transport devices 6.1 to 6.4 are operated in this manner, all of the cross-winding stations 4 on one machine side can be supplied with sleeves by both sleeve stacks 7.1, 7.2 or 7.3, 7.4, as the case may be. Accordingly, the direction of transport of the sleeve transport device 6 is indicated by arrows pointing in both directions. Thus, on the one hand, a sleeve 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 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.

(17) This arrangement can be more favorable in terms of space requirements and allows additional sleeve stacks, similar to those shown in FIG. 1 and FIG. 2, to be arranged on the spinning-mill machine 1 following the respective sleeve stack. Thus, the capacity of the stackable sleeves is even more expandable.

(18) Through a connection of the sleeve stacks 7.1, 7.3 or 7.2, 7.4, as the case may be, or through a corresponding device that moves sleeves to the other side of the machine, the sleeve stacks 7.1 to 7.4 can also enable the supply of sleeves for both machine sides. This is illustrated in FIG. 4. A spinning-mill machine according to FIG. 3, which features a transfer device 8 at each machine end, is shown there. With the transfer device 8, sleeves can be conveyed from one machine side to the other machine side, as indicated by the double arrow. However, the transfer device can also be arranged in the middle of the spinning-mill machine, where the sleeve transport devices 6.1 to 6.4 end. Similarly, such a transfer device 8 is also possible with other embodiments of the invention, such as those of FIG. 1 or 2. The transfer device 8 can also be provided simply by a deflection of the sleeve transport devices 6.1 to 6.4, such that the sleeves are thus conveyed to the other side.

(19) 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.
