Definitions

  • the present invention relates to a method for operating a textile machine, in particular a spinning or winding machine, with a large number of identical work stations arranged next to one another and with at least one suction channel which extends along the work stations, which is connected to a vacuum source and which, in regular operation, Textile machine is acted upon by a working air flow, wherein in the process of the suction channel is briefly acted upon by a cleaning air flow.
  • the suction system contains at least one suction channel, which is assigned a large number of suction points and which is connected to a suction device.
  • the suction system is briefly switched off at intervals by opening a large suction cross-section subjected to a strong air current.
  • the suction channel has a passage which can be closed with an additional flap or a slide and has a large attachment cross-section.
  • the object of the present invention is to simplify the method known from the prior art. Furthermore, a correspondingly simplified textile machine is to be proposed.
  • a method for operating a textile machine in particular a spinning or winding machine, with a large number of similar work stations arranged next to one another and with at least one suction duct extending along the work stations, which is connected to a vacuum source and which, during regular operation of the textile machine, a working air flow is applied.
  • the suction channel is briefly exposed to a stream of cleaning air.
  • the cleaning air flow is generated by opening a shut-off element at at least several work locations from the large number of work locations, by means of which a vacuum-consuming working element and/or a vacuum-consuming maintenance element of the individual work location can be shut off from the suction duct.
  • a cover element of a rotor and/or opening roller housing is opened at the several work locations in order to generate an increased cleaning air flow. As a result, a large intake opening is released at the several work locations and a correspondingly high volume flow can be provided for the cleaning air flow.
  • a textile machine that has also been proposed, in particular a spinning or winding machine, has a large number of similar work stations arranged next to one another and at least one suction channel which extends along the work stations and which is connected to a vacuum source and to which a working air flow is applied during regular operation of the textile machine.
  • the textile machine also has a control unit that is designed to carry out the method.
  • shut-off elements at the several work stations are preferably opened simultaneously in order to generate the cleaning air flow.
  • shut-off elements and/or the cover elements are located at a first end of the textile machine that faces away from the vacuum source. This can be achieved that the cleaning air flow almost the flows through the entire length of the suction channel and the suction channel is thus freed of fiber accumulations, pieces of thread and the like over its entire length.
  • shut-off elements of working points which are located, for example, in a central area of the textile machine or closer to the vacuum source.
  • the textile machine is designed as a rotor spinning machine, with each work station having a rotor spinning device connected to the suction channel, which can be shut off from the suction channel by means of a shut-off element.
  • the shut-off elements and/or the cover elements of the rotor spinning devices are opened at the several work stations in the method.
  • each of the work stations has a suction nozzle and/or a thread storage nozzle, which can be shut off from the suction channel by means of a shut-off element.
  • the shut-off elements of the suction nozzles and/or the thread storage nozzles are opened at the several work stations. These are also present on the textile machine anyway and can be used advantageously to generate the cleaning air flow. If the suction nozzles and/or the thread storage nozzles are connected to a separate suction channel which is only provided for the suction nozzles and/or the thread storage nozzles, then this suction channel can be advantageously cleaned as a result.
  • the cleaning air flow of the suction channel can be increased by opening the shut-off elements of the suction nozzles and/or thread storage nozzles.
  • a cleaning air flow that is increased compared to the working air flow is generated.
  • “increased” means that a higher volume flow is generated for the cleaning air flow than in regular operation.
  • the cleaning air flow, which is increased compared to the working air flow can be generated, for example, by opening the shut-off elements of the suction nozzles and/or the yarn storage nozzles in addition to the shut-off elements of the rotor spinning devices.
  • a cleaning air flow that is higher than the working air flow can be generated by opening the cover elements of the rotor spinning devices in addition to the shut-off elements of the rotor spinning devices.
  • the rotor spinning devices usually have a combined rotor and opening roller housing, which is closed with a cover element.
  • shut-off elements and/or the cover elements are opened after the textile machine has been started and before the start of regular operation of the textile machine.
  • the regular spinning operation or the regular operation of the textile machine is not disturbed by this.
  • the vacuum source is arranged at a second end of the textile machine.
  • the shut-off elements and/or the cover elements are periodically opened and closed several times, so that the cleaning air flow in the suction duct is made to oscillate.
  • the optimal frequency of opening and closing depends on the length of the textile machine and thus also on the suction channel. This facilitates the removal of dirt.
  • At least one dirt belt suction device is also opened to generate the cleaning air flow.
  • the intake cross section can be further enlarged and a high-volume cleaning air flow can thereby be generated.
  • the textile machine it is correspondingly advantageous if it has at least one dirt belt suction device.

  • the thread 23 is fed from the take-off device 20 to a winding device 21 where it is wound onto a spool 22 .
  • the spinning machine can be designed, for example, as a rotor spinning machine and then has an opening roller as the feed device 19 and a rotor spinning device 11 as the spinning device (see Fig Figures 2 and 3 ) on.
  • the spinning machine or the textile machine 1 could also be designed as an air spinning machine, the work stations 2 of which then have a drafting system as the feed device 19 and an air spinning nozzle as the spinning device 10 .
  • the textile machine 1 it would also be conceivable for the textile machine 1 to be designed as a winding machine. In this case, instead of the feed device 19 and the spinning device 10, a pay-off spool would be present. In the yarn path after the take-off device 20, the different types of textile machine 1 have a largely identical structure.
  • the spinning device 10 is shown as the working element 7 consuming the vacuum.
  • the work station 2 can also have other working elements, including working elements 7 that use vacuum.
  • several maintenance bodies including vacuum-consuming maintenance bodies 8 (see Fig Figures 2 and 3 ) to be available.

  • the spinning devices 10 can each be blocked off from the suction channel 3 by means of a blocking element 6 or can be connected to it.
  • the suction channel 3 is in turn connected to a vacuum source 4 which is arranged in one of the frames 18 at a second end 17 of the textile machine 1 .
  • a working air stream (not shown) flows through the suction channel 3, which supplies the spinning devices 10 with negative pressure.
  • the textile machine 1 also has at least one control unit 16 for controlling the various activities on the textile machine 1 .
  • shut-off elements 6 of the spinning devices 10 at the first end 9 of the textile machine 1 are opened to generate the cleaning air flow 5 .
  • These spinning devices 10 are thus located at the first end 9 of the textile machine, opposite the vacuum source 4 , so that the cleaning air flow 5 covers the entire suction channel 3 .
  • both the number and the location of the work stations 2 whose shut-off elements 6 are opened can vary.
  • FIG 2 shows a work station 2 of a textile machine 1 configured as a rotor spinning machine in a schematic, partially sectioned representation.
  • the feed device 19 is designed as an opening roller (not numbered), which in the present case is arranged in a combined rotor and opening roller housing 25 which is closed by means of a cover element 27 .
