Definitions

  • the invention relates to a device for extruding, stretching and winding a group of film tapes or monofilaments according to the preamble of claim 1.
  • a film is extruded from a thermoplastic material, which is preferably cut into a plurality of film tapes as a flat film.
  • the sheet of ribbon is then passed over a plurality of take-off rollers and stretching rollers which stretch the ribbon.
  • the foil tapes are separated and wound into coils through a large number of winding stations.
  • a generic device is for example from the US 6,439,498 B1 known.
  • the winding points on a frame wall are held in a plurality one above the other and in a plurality side by side.
  • the winding stations each have a projecting winding spindle, on the free end of which a winding tube can be attached.
  • Each of the winding points held on the frame wall is supplied with one of the foil tapes which are wound into a coil within the winding point.
  • a manual bobbin change takes place by an operator using the full bobbin with an auxiliary device detaches from the spindle and feeds a new sleeve to the winding station.
  • the operation of the winding stations and the removal of the full coils is thus carried out on one operating side of the frame wall. With a large number of winding points on a frame wall, collisions between operation and removal are inevitable.
  • Another object of the invention is to provide a winding station device which enables a continuous winding process with little operating effort.
  • the device according to the invention for extruding, stretching and winding up a group of foil tapes or monofilaments is characterized in that the bobbin can be removed independently of the operation of the winding stations.
  • the winding points are designed in such a way that the wound coils on the frame wall one to the operating side opposite Doff side are ready for clearing. Due to the physical separation between the operating side and the doffing side, collisions are impossible with a large number of winding stations.
  • the removal of the fully wound coils can advantageously be improved further by assigning a doffing path to the winding points on the doffing side. So there is the possibility to use automated clearing devices to take over the bobbin removal.
  • an operating aisle is assigned to the winding stations on the operating side of the frame wall. In this way, quick operability can be guaranteed even in the event of process interruptions due to individual ribbon breaks.
  • the winding stations each have a movable bobbin holder for receiving a bobbin tube, which can be pivoted between the operating side and the doffing side .
  • the winding tube can be wound up on the operating side with a thread and can then be placed on the Doff side as a bobbin for pivoting the bobbin holder.
  • the winding points on the doff side of the frame wall each have a coil storage device, so that at least one of the several coils can be kept ready for clearing on the doff side of the frame wall.
  • the winding points on the doff side of the frame wall each have a sleeve storage device with an outlet opening towards the operating side, through which empty sleeves are kept ready for delivery to the bobbin holder.
  • An automated spool change can thus be carried out.
  • the variant of the invention is also provided, in which the winding stations on the operating side each have a position changer with an oscillating traversing thread guide, which has at least one film band or monofilament during a bobbin winding phase and during a bobbin changing phase leads.
  • the traversing thread guide can be guided in a holding position in which it remains during the bobbin changing process.
  • the development of the invention is particularly advantageous, in which the winding stations each have a suction device for receiving at least one of the film tapes or monofilaments, and in which the suction device of the winding stations has a processing device connected to reuse of a film or filament material. This means that the material sucked in during a bobbin change can be reused. Material waste is advantageously avoided.
  • the device according to the invention is further characterized in that the winding tube on the movable bobbin holder can be driven or braked depending on the function and position of the bobbin holder.
  • the bobbin holder can thus be moved back and forth between a bobbin holder with a braked bobbin tube and a thread feed side with a driven bobbin tube for winding a bobbin.
  • the tensioning plate on the spool holder which can be driven to transmit the torque, is preferably driven via a belt drive in order to be kept as compact as possible within a frame wall with several winding points next to one another.
  • an electric motor can be arranged on the spool holder parallel to the spool sleeve in order to drive the belt drive placed on an outer side of the spool holder.
  • the development of the winding point is particularly advantageous, in which a position-changing device with a position-changing drive is provided for driving a traversing thread guide, and in which the traversing drive and the bobbin drive are coupled to one another by an electronic control gear.
  • a precision cross-wound bobbin with predetermined crossing angles which is determined by the ratio of the bobbin peripheral speed and the traversing frequency, can thus be wound.
  • the traversing drive can advantageously be carried out by means of a reversible thread shaft and an electric motor. In principle, however, the traversing drive could also be formed by a belt drive and an electric motor.
  • the coil drive is coupled to a dancer arm control device. This ensures that the ribbon or monofilament is wound onto the spool with even tension.
  • one of the tensioning plates has a catching device which interacts with at least one auxiliary device for catching and winding. In this way, a ribbon of film continuously taken up in a suction device can be fed to the catcher on the clamping plate, so that the ribbon can be caught and separated without manual support.

  • the coils 22 can be cleared and transported away either manually by an operator or automatically by a doffer.
