Definitions

  • the invention relates to a method for optimizing the production efficiency of a spinning machine by reducing the production speed with an increased number of thread breaks and increasing it with a reduced number of thread breaks.
  • a textile machine with a plurality of processing stations wherein each processing station has an actuating element and a sensor device, and the individual actuating elements and sensor devices are connected via a communication structure in order to allow rapid adaptation of the entire textile machine to the detected states.
  • a method of the type mentioned Eigens for optimizing the production performance of the entire spinning machine is by a patent application 10 30 432 known to the Soviet Union. According to this patent application, the overall machine speed is adapted to the yarn breakage rate. The method is explained using the example of a false twist spinning machine.
  • the invention is based on the object of taking due account of the different yarn breakage rates at the individual spinning stations for optimizing the production output.
  • the amount of the given spin rotation is adjusted accordingly.
  • a controller which also includes an evaluation, assigned.
  • An air jet spinning machine contains a plurality of spinning stations, of which only four spinning stations 1, 2, 3 and 4 are shown in the figure are.
  • Each spinning station 1, 2 ... is used to spin a thread 5 from a staple fiber 6 and contains as essential components an air jet unit 7, preferably designed as a three-cylinder drafting drafting 8, further a pair of take-off rollers 9 and a winding device, not shown, the the withdrawn thread 5 is fed in withdrawal direction B.
  • each drafting system 8 includes an input roller pair 10 to which the staple fiber strand 6 to be stretched is fed in the feed direction A, a pair of apron rollers 11 looped around by guide straps 12 and 13, and an exit roller pair 14 on which the draft zone of the drafting 8 is completed.
  • the staple fiber strand 6 is stretched in a known manner to the desired fineness.
  • Each air jet unit 7 contains a feed channel 15, to which the stretched, still rotation-free staple fiber strand 6 is supplied for imparting its spin rotation.
  • the air jet unit 7 further includes a yarn withdrawal channel 16 for the spun yarn 5.
  • compressed air nozzles 17 are arranged, the outlet openings lead into a vortex chamber 18 where the actual twist distribution takes place.
  • a thread monitor 19 is arranged, which causes the shutdown of the respective spinning station 1, 2 ... at a yarn breakage.
  • a common first drive motor 20 is provided for driving both the pair of output rollers 14 and the pair of take-off rollers 9 of each spinning station 1, 2 ..., so that the roller pairs 14 and 9 are always driven together be, but with a slight difference in speed, which carries a desired tensioning distortion of the thread 5.
  • the drive motor 20 is adjustable in its speed.
  • the pair of input rollers 10 and the Riemchenwalzencru 11 of the drafting system 8 is each driven by a common second drive motor 21.
  • the Riemchenwalzencru 11 must run much faster than the pair of input rollers 10, since in this area already the Vorverzug the staple fiber Association 6 takes place.
  • the drive motor 21 is adjustable in its speed.
  • the production capacity of the air jet spinning machine is to be optimized by running each individual spinning station 1, 2 ... at an optimized speed.
  • each individual spinning station 1, 2 ... monitored separately with respect to the number of yarn breaks and adjusted to an optimized production speed, which is reduced at a relatively high yarn breakage rate and increased at a relatively low yarn breakage rate.
  • a yarn breakage counter 22 is present at each individual spinning station 1, 2. He is directly connected to the associated thread monitor 19.
  • Each spinning station 1, 2... Contains a controller 23 which, inter alia, has an evaluation device for the number of registered yarn breaks. The controller 23 is able to regulate the drive motors 20 and 21 to an optimized production speed at which the number of thread breaks does not exceed a predetermined level.
  • each of the height of the divided spin rotation in relation to the delivery speed remains constant, it is provided at each spinning station 1, 2 ... also the supplied compressed air as a function of the respective Regulate production speed.
  • Each spinning station 1, 2 ... is connected via a branch 26 with a machine compressed air line 27.
  • a compressed air sensor 24 and a throttle valve 25 may be provided, so that via the controller 23, the throttle valve 25 is actuated and the spinning pressure can be regulated.
