Definitions

  • the invention relates to a method for optimizing the production output of a spinning machine by reducing the production speed with an increased number of yarn breaks and increasing it with a reduced number of yarn breaks.
  • a method of this kind is known by a patent application 10 30 432 of the Soviet Union. According to this patent application, the machine speed is adjusted overall 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 object is achieved in that each individual spinning position of the spinning machine is monitored separately with regard to the number of yarn breaks and is adjusted to an optimized production speed.
  • each individual spinning station is assigned a controller which at the same time contains an evaluation device.
  • 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 strand 6 and contains as essential Bestandtei ⁇ an air jet unit 7, preferably designed as a three-cylinder drafting drafting 8, further a pair of take-off rollers 9 and not one Spooling device shown, the Tozo ⁇ gene 5 yarn in the drawing direction B is supplied.
  • each drawing unit 8 comprises an input roller pair 10 to which the staple fiber dressing 6 to be drawn is fed in the feed direction A, and also a pair of apron rollers 11 which is looped around by guide straps 12 and 13, as well an output roller pair 14, at which the drafting zone of the drafting system 8 is completed.
  • the staple fiber strand 6 is stretched in a known manner to the desired fineness.
  • Each air nozzle 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 in a thread break the Still ⁇ the respective spinning station 1, 2 ... triggers.
  • a common first drive motor 20 is provided for driving both the output roller pair 14 and the take-off roller pair 9 of each individual spinning station 1, 2 ..., so that the roller pairs 14 and 9 always be driven together, but with a small amount of speed difference, which takes into account 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 pair of apron rollers 11 of the drafting system 8 are each driven by a common second drive motor 21.
  • the apron roller pair 11 must run much faster than the Ein ⁇ pair of roller 10, since in this area already the pre-distortion of the staple fiber strand 6 takes place.
  • the drive motor 21 can also be regulated in its speed.
  • the normal spinning process is sometimes interrupted, which reduces the production capacity at the relevant spinning station 1, 2 ... Since no further staple fiber structure 6 is fed to the drafting unit 8 in the event of a yarn breakage, it is provided-controlled by the thread monitor 19 -that the drive motors 20 and 21 are then stopped. The compressed air supply to the compressed air nozzles 17 is switched off at the maintenance-requiring spinning station 1, 2 ....
  • 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 ... ge separately monitored with regard to the number of thread 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 of the individual spinning stations 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 adjust the drive motors 20 and 21 to an optimized production speed at which the number of thread breaks does not exceed a predetermined amount.
  • 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 can be provided at each branch 26, so that the throttle valve 25 can be actuated via the regulator 23 and the spinning pressure can be regulated.

Abstract

L'invention concerne un procédé pour optimiser le rendement de la production d'un métier à filer par surveillance séparée du nombre de ruptures de fil à chaque point de filature individuel et par réglage sur une vitesse de production optimisée. Dans un métier à filer à jet d'air, l'air comprimé acheminé aux points de filature est réglé en fonction de la vitesse de production respective.
