Definitions

  • the invention relates to a method for removing a blockage in a false twist spinning unit as described for example in the preamble of the first claim.
  • a number of false twist spinning devices are already known in which a fiber sliver emitted from a can is drawn in a drafting device for each spinning station, spun in a false twist spinning unit and the finished yarn is then wound up in a winding unit.
  • a yarn monitoring device is usually provided, which either reports so-called thick spots in the yarn or the absence of the yarn.
  • the whole can be done either manually or by means of a controlled device.
  • the yarn production is also stopped immediately in order to determine the reason for the missing yarn.
  • the fiber material in the suction part must be worked out manually with a suitable tool in order to then carry out the piecing process again.
  • this object is achieved by the steps defined in the characterizing part of claim 1.
  • this method requires a special false-twist spinning unit in which the suction part is designed to be automatically displaceable.
  • a sliver 1 is removed from a sliver can 2 and fed to a drafting device 3.
  • a so-called false twist spinning unit 4 comprises a suction part 5, one or more swirl sensors 6 adjoining it and a pair of take-off rolls 7.
  • the single swirl sensor is mentioned as representative for several.
  • a game monitoring device 9 is provided in the garniank between the pair of draw rollers 7 and a winding unit 8.
  • the fiber structure 10 released by the drafting system 3 is taken over by the suction part 5 and passed on to the swirl sensor 6. Due to the function of the twister 6, a finished yarn 11 is formed, which is taken over by the pair of take-off rollers 7 and passed on to the winding unit 8 via the thread monitoring device 9.
  • the suction part is connected to a suction device 13 by means of a connection 12.
  • the suction part can also work without the suction device 13, provided that the following swirl sensor 6 is a pneumatic swirl sensor with suction effect, which is coupled directly to the suction part.
  • the whole, d. H. from the sliver can 2 to the winding unit 8, is referred to as the spinning station.
  • FIG. 2 shows that, for cleaning the suction part 5, it is lifted or swung away from the operating position (shown with a broken line) into a cleaning position (shown with a solid line).
  • Lifting or swiveling away. the return to the operating position is carried out either manually or by a device 15 which is assigned to each spinning station or a moving cleaning machine.
  • This variant offers the advantage that the cleaning process does not have to be carried out within the operating arrangement of the elements.
  • the cleaning process can be repeated if the piecing process is successful.
  • connection 12 to the suction device 13 is interrupted or not interrupted for cleaning the suction part 5.
  • FIG. 3 a variant is shown, in which the suction part 5 is blocked by means of a device 16 for exchanging the suction part in an ejection position (shown with dashed line), in which the suction part 5 is removed from the spinning position, which is indicated by an arrow E is hinted at.
  • the removal of the blocked suction part and the detection of an operational suction part can be carried out manually or by means of the device 16 mentioned.
  • Ready-to-use and clogged suction parts can be accommodated in multiple magazines.
  • FIGS. 4 and 5 show a combination of the method steps which were set out using FIGS. 2 and 3.
  • the suction part 5 is cleaned in the raised position (shown with dashed lines) by means of the cleaning element 14 and then checked for the degree of cleaning by means of a control element 17 and then reinserted into the operating position (shown with a solid line), in order to then do so carry out the piecing process again.
  • the piecing process can then be carried out again.
  • checking the suction part 5 after cleaning by means of the cleaning element 14 can also be used for the cleaning methods described with FIG. 2.
  • connection 12 between the suction part 5 and the suction device 13 can also be interrupted for the cleaning process of the suction part 5 in the method shown with FIGS. 4 and 5.
  • the swirl sensor 6 can be a pneumatic or a mechanical swirl sensor. Any measures during piecing using a mechanical swirl sensor to take over the fiber material emitting from the suction part to the swirl sensor are not part of this invention.
