    Abstract

    The present invention relates to a textile machine having a plurality of workstations of the same type, which produce packages, more particularly cross-wound packages, and having one thread accumulator each and at least one service cart, which can be moved along the workstations. The present invention also relates to a service cart for a textile machine. In order to provide a textile machine having a plurality of workstations having thread accumulators, in the case of which textile machine fault states that occur in connection with the thread accumulator can be automatically eliminated, there is provision for the service cart to have malfunction-eliminating devices for automatically eliminating fault states that occur in the thread accumulator and/or can be attributed to the thread accumulator.

    Claims

    1. A textile machine having a plurality of workstations of the same type, which produce packages, and each of which comprises one thread accumulator and at least one service cart, which is movable along the workstations, characterised in that the service cart has malfunction-eliminating devices for automatically eliminating fault states that occur in the thread accumulator and/or is attributable to the thread accumulator.

    2. The textile machine according to claim 1, characterised in that the malfunction-eliminating devices comprise a cleaning unit for removing thread remnants from the thread accumulator.

    3. The textile machine according to claim 1, characterised in that the malfunction-eliminating devices comprise an optical inspection device for checking the thread accumulator.

    4. The textile machine according to claim 1, characterised in that the service cart comprises a thread joining device.

    5. The textile machine according to claim 1, characterised in that the thread joining device has a thread-seeking nozzle and manipulator for positioning the free thread end in the area of a thread joiner.

    6. The textile machine according to claim 1, characterised in that the thread joining device is designed to arrange the free thread end at a piecing position of the workstation.

    7. The textile machine according to claim 1, characterised in that the service cart comprises thread inspection devices.

    8. A service cart for a textile machine according to claim 1, characterised by malfunction-eliminating devices for automatically eliminating fault states that occur in the thread accumulator and/or is attributable to the thread accumulator.

    9. The textile machine according to claim 1, wherein the packages are cross-wound packages.

    10. The textile machine according to claim 5, wherein the thread joiner is a splicing and/or knotting unit.

    11. The textile machine according to claim 7, wherein the thread inspection devices are optically acting thread inspection devices.

    Description

    BRIEF DESCRIPTION OF THE DRAWINGS

    [0027] An embodiment example of the present invention is explained below with reference to the drawings. In the drawings:

    [0028] FIG. 1 shows a simplified view of a textile machine in the form of a spinning machine, comprising a plurality of workstations.

    DESCRIPTION OF THE PREFERRED EMBODIMENTS

    [0029] FIG. 1 shows a simplified representation of a textile machine 1, which is in the form of spinning machine and has a plurality of workstations 2 arranged adjacent to one another. Each workstation 2 of the textile machine 1 comprises: a sliver source 3, which can be, for example, a spinning can when the workstation 2 in question is a spinning position; a drafting system 4; a spinning device 5; a take-up roller pair 6; a yarn clearer 7; a thread repositioning apparatus 8; a thread accumulator 17; and a cross-wound package 9 of a winding device. A service cart 10 movably mounted on rails 11, 12 running along the textile machine 1. A drive unit 13 arranged at one end of the textile machine 1 is used to drive the textile machine 1.

    [0030] In the case of a malfunction at a workstation 2 in the area of the thread accumulator 17, the service cart 10 is positioned along the textile machine 1 at the workstation 2 that has the malfunction. In the case of a thread break which, for example, has occurred within the thread accumulator 17, the service cart 10 is moved to the workstation 2 in question, is positioned there and begins the fault elimination using the malfunction-eliminating devices, which are not shown here. In the case of a thread break within the thread accumulator 17, the service cart 10 can find the torn thread end lying on the circumferential surface of the cross-wound package 9 by means of a thread-seeking nozzle, which is numbered among the malfunction-eliminating devices. As usual, after the spinning device 5 has been cleaned, handling devices of prior art numbered among the malfunction-eliminating devices convey this thread end, after appropriate preparation, back to the area of the spinning device 5, where this thread end is kept ready for the actual piecing process. At the same time, a defined thread length is unwound by means of the drive of the cross-wound packages 9 and is intermediately stored in the thread accumulator 17.
