Definitions

  • the invention relates to a device for drawing off and winding up threads in a melt spinning process according to the preamble of claim 1.
  • the threads produced as a sheet of threads are pulled off using godets, stretched and then wound parallel to bobbins at the end of the process.
  • godets For this purpose, devices for drawing off and winding are used, which, depending on the manufacturing process, have several godets and several winding points arranged below the godets, which are arranged together in a machine frame. Due to the low overall height and the compactness of such devices, manual operation by an operator can be carried out in a simple manner, especially at the start of a process. In principle, however, today's systems are equipped with auxiliary devices in order to make them easier to use for the operator.
  • the threads in order to be able to distribute and thread the threads of a group of threads to the winding points at the start of a process, it is common for the threads to first be guided over a movable suction injector so that they can be taken over by a thread guide and distributed to the winding points.
  • Such a generic device is known for example from DE 10 2017 004 866 A1.
  • the winding points are distributed in a machine frame along a driven winding spindle.
  • a godet carrier is supported on an upper side of the machine frame, on which several godets are arranged for drawing off a group of threads.
  • a thread laying device is provided which has several movable thread guides.

  • the thread guides are attached to the guide rail, which is moved by the operator.
  • thread laying devices are also known in such devices, in which the work of the operator is further relieved in that the guidance of the thread guides in the guide rail between the feed positions and the operating positions can be controlled by an actuator.
  • Such a device can be found, for example, in WO 2016/180679.
  • the activity of the operator at the start of a process is limited to applying the group of threads to the godet jackets of the godets with a single loop before distribution to the winding points.
  • a further object of the invention is to provide a generic device for drawing off and winding up threads, the thread laying device of which enables automated operation.
  • the thread laying device has a movable feed roller in the region of the godets, which can be guided between a feed position and an operating position for laying the threads on the circumference of the godets.
  • the particular advantage of the invention is that at the start of the process, the guidance of the threads by means of a suction gun requires only simple linear movements in order to keep the group of threads ready to be taken over by the thread laying device.
  • a rotatable feed roller which can be guided between a feed position and an operating position, is provided for laying the threads on the circumference of the godet sleeves. Even with larger deflections of the threads, undesired increases in thread tension can be avoided by the feed roller.
