Definitions

  • the invention relates to a method and an apparatus for winding Continuous threads or yarns on bobbins with continuous bobbin change for production of bobbins with a thread reserve suitable for processing using of an automatically changing winder, which is also suitable for smooth cores and sensitive continuous filament yarn is suitable.
  • the process is characterized by a loss-free change of coils, high reliability and the Possibility to use simple cylindrical sleeves to form a thread reserve suitable for processing.
  • Thread winders are fundamentally different in various embodiments known.
  • DE-OS-25 24 415 is an automatic winder for yarns described, which enables the formation of a thread reserve.
  • Two coil holders are opposite on this winder on a rotatable around their center Plate stored. Each coil holder can be driven by a motor.
  • the supply thread is fed by a guide from the Traversing thread guide lifted out and onto the sleeve edge into the thread reserve track postponed.
  • a guide element must thread the keep the wound area of the full spool from losing speed
  • the thread slides into the smaller diameter of the sleeve edge prevent.
  • the sleeve is in the area of the thread reserve with a catch slot equipped, which clamps the thread and the thread between the outgoing Coil and the empty tube tears. After forming the thread reserve, the thread is in returned to the traversing area and taken over by the traversing thread guide.
  • the automatic winder with thread reserve device described in DE-OS-25 24 415 is designed for the use of thread tubes with a catch slot.
  • This Sleeves have some disadvantages compared to smooth sleeves. They are more complex in production, due to the contamination of the catch slot only once use and difficult to recycle after use.
  • a similar winder that works without the formation of a thread reserve is in EP-A 0-359 453.
  • This winder is used especially for elastanes and can also work with a sleeve without a slot. After the rotation of the The full bobbin holder, the thread, is braked in the direction of rotation of the sleeve between full and empty tube loses tension, adheres to the empty tube and is taken away by this. This creates a new tension until the connection breaks when the breaking limit is exceeded.
  • the thread reserve according to DE-OS-25 24 415 is on the winder from the EP-A-0 359 453 is not transferable since there is a risk of delicate yarns because of the voltage losses caused by the friction on the guide element between the full coil and empty sleeve caused to run onto the drive roller. The security of There is no longer a change of bobbins.
  • a thread reserve suitable for processing is also characterized by a simple one Handling off. This is guaranteed when the thread reserve winding is good accessible on the edge of the tube outside the package and a thread from the Thread reserve runs into the bobbin.
  • the one described in EP-A-0 359 453 Automatic winder is created when the connection between the full spool and Empty tube inevitably an unfixed thread end undefined length. This Thread end is common when using a conventional thread reserve device included in the coil. A quick assignment of the right connection between thread reserve winding and bobbin is no longer possible.
  • the invention is based, without using sleeves the task Catch slot to wind sensitive filament yarns securely, the full spool automatically, lossless and with high security against an empty tube change and form a thread reserve at the beginning of the winding cycle is processable according to the criterion listed above. In particular, should the omission of additional guide elements between the full coil and the empty tube Contribute to increased security of change.
  • the object is achieved in that the thread during the Alternating from the full spool to the empty tube is held in the winding area and after the transition to the empty tube first a small false wrap in builds up this area. Then the incoming thread with the help of a arranged in front of the drive roller guide in the area of the thread reserve track postponed. The annoying false winding in the middle area of the bobbin will then disappear also pneumatically or mechanically in the area of the thread reserve shifted, the tear-off end being fixed in the false wrap. After the training the thread reserve becomes the incoming thread again from the traversing thread guide accepted and the build-up of the winding begins.
  • the invention relates to a method for winding continuous filaments or Yarns on bobbins with continuous bobbin change by feeding and Winding the thread on a bobbin driven by a roller Traversing the thread along the bobbin axis, separating the full bobbin from the drive roller with takeover of the drive of the full reel by a separate drive and further winding of the yarn in the middle area of the Full coil, screwing in a separately driven empty tube until contact with Drive roller and thread, braking the full bobbin, recording the running Thread through the empty tube and tearing of the thread between the empty tube and Full spool, formation of a false winding in the middle area of the empty tube, Shift the position of the incoming thread to the edge area of the empty tube to form a thread reserve outside the traversing area, shifting the formed miswraps in the area of the thread reserve, return of the running thread to the traversing unit to form the bobbin and Exchange of the full spool for an empty tube.
  • the process according to the invention is advantageous over the known ones Process for automatic bobbin change when winding sensitive Yarn increases the yield of full bobbins.
  • the operating effort is because of less susceptibility to failure when changing less, it can be simple sleeves can be used without catch aids or catch slots and the built Thread reserve can be used with every bobbin.
  • Fig. 1 shows a winder working according to the inventive method during normal coil build.
  • the winder has in particular frequency-controlled motors for driving the traversing unit 1, the drive roller 2 and the coil holder 3, 4 and a gear motor for driving the turret 5.
  • a winding unit with two consecutive Running bobbins. It is possible in a variant of the device with axial extended brackets to wind other bobbins in parallel.
  • the thread 6 is supplied by a delivery unit 7 via a Traversing thread guide 8 of the bobbin 9 under construction, which is supplied by Driving roller 2 is driven. At the end of the term of the coil 9 Change initiated.
  • the drives of the Empty sleeves 18 and the drive of the bobbin holder 3 equipped with full bobbins 9 or 4 started.
  • the drive roller 2 is lifted off the full spools 9 (see Fig. 2).
  • the coil holders swap places by 180 °.
  • Spool change is the drive roller 2 on the equipped with empty tubes Coil holder 3 lowered (see Fig. 3) and drives it. She comes here however, not in contact with the sleeves 18, but via a thrust ring 10 kept at a short distance. In this step, the thread 6 runs over the empty tube 18.
  • the bobbin holder 4 with the full bobbins 9 is braked.
  • the through that Braking the resulting speed difference between delivery plant 7 and Full bobbin 9 causes the empty tube 18 to be supplied with more thread material, as the full spool decreases.
  • the excess is wound onto the empty tube 18, and exerts a tensile force on the connection 11 between the empty tube and the full spool out. If the tensile force exceeds the breaking limit, the connection breaks and the Thread 6 winds exclusively on the empty tube 18 and forms an im Missing winding lying in the center of the sleeve 14.
  • the bobbin holder drives are now switched off.
  • the guide plate 12 becomes parallel moved to the bobbin holder so that the incoming thread 6 in the area of Thread reserve track 15 is wound on the empty tube.
  • 7 and 8 is the Displacement of the false winding from the center into the area of the thread reserve track shown.
  • the following is a nozzle 16 on the thread reserve track Positioned opposite side of the false wrap 14 and with adjustable compressed air acted upon (see Fig. 7).
  • the nozzle 16 is then in the direction of Thread reserve track 15 moves.
  • the air jet pushes with the movement of the nozzle 16 the false wrap 14 in front of itself except for the position of the thread reserve track 15.
  • the tearing end of the thread becomes in the false wrap during shifting fixed.
  • the air supply to the nozzle is switched off and the nozzle in returned to their starting position.
  • the number of related nozzles 16 corresponds to the thread of the winder. If more than one nozzle is used, as in Appropriate measures must be taken to ensure that the example shown here is: the same amount of air is applied to each nozzle.
  • the quality of the method according to the invention follows from the following Examples 1 and 2.
  • An automatic winder is compared according to EP-A 0 359 453, which works with a thread reserve formation according to German laid-open specification 25 24 415 and a winder that works according to the inventive method. Both winders are with smooth Fitted sleeves, the conditions upstream of the winder are identical.
  • the Continuous filament yarn of the example to be wound is an elastane.
  • Each bobbin is examined individually when assessing the thread reserve. Here two thread ends integrated into the winding lead to devaluation.
