Definitions

  • the invention relates to a method and an apparatus for winding continuous threads or yarns on bobbins with a continuous bobbin change for the production of bobbins with a processing reserve thread reserve using an automatically changing winder, which is also suitable for smooth tubes and sensitive continuous filament yarns.
  • the process is characterized by a loss-free change of bobbins, a high level of change reliability and the possibility of using simple cylindrical sleeves, with the formation of a thread reserve suitable for processing.
  • Thread winders are basically known in a wide variety of embodiments.
  • an automatic winder for yarns is described which enables the formation of a thread reserve.
  • two bobbin holders are mounted opposite each other on a plate that can be rotated around their center.
  • Each coil holder can be driven by a motor.
  • the motors of the bobbin holder are started, the driving roller is lifted off and the plate is rotated against the direction of rotation of the bobbin holder.
  • the thread coming in from the supplying plant is lifted out of the traversing thread guide by a guide element and pushed into the thread reserve track at the edge of the sleeve.
  • a guide element must hold the thread in the wound area of the full bobbin in order to prevent a loss of speed due to the thread sliding off into the smaller diameter of the tube edge.
  • the sleeve is equipped with a catch slot which clamps the thread and the thread between the outgoing Coil and the empty tube tears. After the thread reserve has been formed, the thread is 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.
  • These sleeves have some disadvantages compared to the smooth sleeves. They are more complex to manufacture, can only be used once due to the contamination of the catch slot and are difficult to recycle after use.
  • the thread reserve according to DE-OS 25 24 415 is not transferable to the winder from EP-A 0 359 453, since there is a risk that sensitive yarns on the drive roller due to the tension losses caused by the friction on the guide element between the full bobbin and the empty tube accumulate. The safety when changing the bobbin is no longer guaranteed.
  • a thread reserve suitable for processing is also characterized by simple handling. This is ensured when the thread reserve winding is easily accessible at the edge of the tube outside the package and a thread runs from the thread reserve into the bobbin.
  • EP-A 0 359 453 when the connection between the full bobbin and the empty tube is torn off, an unfixed thread end of an undefined length inevitably arises. This thread end is common when using a conventional thread reserve device included in the coil. It is no longer possible to quickly assign the correct connection between the thread reserve winding and the bobbin.
  • the invention has for its object to securely wrap sensitive filament yarns using sleeves without a catch slot, to change the full bobbin automatically, without loss and with a high degree of certainty against an empty tube and to form a thread reserve at the beginning of the winding cycle, which is suitable for processing according to the criterion listed above .
  • the omission of additional guide elements between the full coil and the empty tube is intended to increase the reliability of the change.
  • the object is achieved in that the thread is held during the change from the full bobbin to the empty tube in the winding area and after the transition to the empty tube first builds up a small false winding in this area. Then the incoming thread is shifted into the area of the thread reserve track with the aid of a guide element arranged in front of the drive roller. The disruptive false winding in the central region of the bobbin is then also moved pneumatically or mechanically into the region of the thread reserve, the end of the tear being fixed in the false winding. After the thread reserve has been formed, the incoming thread is again taken over by the traversing thread guide and the build-up of the winding begins.
  • the invention relates to a method for winding continuous threads or yarns on bobbins with continuous bobbin change by feeding and winding the thread on a bobbin driven by a roller with traversing of the thread along the bobbin axis, separating the full bobbin from the drive roller with taking over the drive of the Full bobbin through a separate drive and further winding of the yarn in the middle area of the full bobbin, screwing in a separately driven empty tube until contact with the drive roller and thread, braking of the full bobbin, picking up the running thread through the empty tube and tearing of the thread between empty tube and full bobbin, formation of a Faulty winding in the middle region of the empty tube, shifting the position of the incoming thread to the edge region of the empty tube to form a thread reserve outside of the traversing region, shifting the false winding formed in the region of the thread reserve, returning the running thread to the traversing unit to form the bobbin and exchange the full bobbin for an empty tube.
  • the yield of full bobbins is advantageously increased compared to the known methods for automatic bobbin changing when winding sensitive yarn.
  • the operating effort is lower due to the lower susceptibility to faults when changing, simple sleeves can be used without catch aids or catch slots and the built-up thread reserve can be used with every bobbin.
  • the winder has, in particular, frequency-controlled motors for driving the traversing unit 1, the drive roller 2 and the bobbin holder 3, 4 and a geared motor for driving the turret 5.
  • a bobbin unit with two bobbins located one behind the other.
  • the thread 6 is fed from a feed mechanism 7 via a traversing thread guide 8 to the bobbin 9 which is being built and which is driven by the drive roller 2.
  • the change is initiated.
  • the drives of the bobbin holder 3 or 4 equipped with empty sleeves 18 and the drive of the bobbin holder 3 or 4 filled with full bobbins 9 are started.
  • the drive roller 2 is lifted off the full spools 9 (see FIG. 2).
  • the drive roller 2 is lowered onto the bobbin holder 3 equipped with empty tubes (see FIG. 3) and drives it. However, it does not come into contact with the sleeves 18, but is kept at a short distance via a thrust ring 10.
  • the thread 6 runs over the empty tube 18 in this step.
  • a thread connection is formed between the empty tube and the full spool.
  • the incoming thread 6 is lifted out of the traversing thread guide 8 with a displaceable or pivotable guide plate 12 (see FIG. 4).
  • the sheet 12 guides the thread 6 so that it runs on the spools on a narrow path within the winding area.
  • the sheet has a number of recesses 13 corresponding to the number of threads, the opening of which is somewhat larger at the beginning than the traversing width in order to catch the thread 6 safely.
  • the recess becomes narrower in order to achieve the safe guidance of the thread on the narrow path.
  • Fig. 5 shows the separation of the thread connection between the full bobbin and empty tube.
  • the bobbin holder 4 with the full bobbins 9 is braked.
  • the speed difference between the delivery mechanism 7 and the full bobbin 9 caused by braking 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. If the tensile force exceeds the breaking limit, the connection breaks and the thread 6 winds exclusively on the empty tube 18 and thereby forms a false winding 14 lying in the center area of the tube.
  • the bobbin holder drives are now switched off.
  • the guide plate 12 is displaced parallel to the bobbin holder in such a way that the incoming thread 6 is wound onto the empty tube in the region of the thread reserve track 15.
  • 7 and 8 show the displacement of the false winding from the center into the area of the thread reserve track.
  • a nozzle 16 is positioned on the side of the false winding 14 facing away from the thread reserve track and is supplied with adjustable compressed air (see FIG. 7). The nozzle 16 is then moved in the direction of the thread reserve track 15. With the movement of the nozzle 16, the air jet pushes the false winding 14 in front of it to the position of the thread reserve track 15. The end of the thread that is torn off is fixed in the false winding during the displacement.
  • the air supply to the nozzle is switched off and the nozzle is returned to its starting position.
  • the number of nozzles 16 used corresponds to the thread of the winder. If more than one nozzle is used, as in the example shown here, suitable measures must be taken to ensure that the same amount of air is applied to each nozzle.
  • the incoming thread 6 is fed back from the guide plate 12 into the winding area (see FIG. 9). The guide plate 12 is then moved back into the rest position and the thread 6 is transferred to the traversing thread guide 8. The coil build-up then begins again in the region of the winding 17.
  • Each bobbin is examined individually when assessing the thread reserve. Here, two thread ends integrated into the winding lead to devaluation.
