Definitions

  • the invention relates to a device for laying a thread for winding a bobbin according to the preamble of claim 1.
  • the thread is guided back and forth within a laying stroke by two thread guides driven in opposite directions.
  • the thread guides are formed by several wings attached to a rotor, which cooperate with a second rotor with a corresponding number of wings.
  • the rotors are driven in opposite directions, the thread being guided alternately through one of the wings on a thread guide.
  • Such devices for laying a thread are particularly suitable for relatively high laying speeds ge. Basically, however, they have the disadvantage that at the stroke ends of the laying stroke the meeting of the thread guides moving in opposite directions has to be coordinated with one another in order to avoid uncontrolled thread guidance.
  • the invention is based on the last-mentioned variant of the laying devices, since this has a higher flexibility with regard to coil formation.
  • Another aim of the invention is to develop the generic device for laying a thread in such a way that a thread mass that is as uniform as possible can be laid down during the stroke reversal without falling thread turns.
  • a thread guide ruler which extends along the laying stroke and which interacts with the thread guide for laying the thread, the thread guide having separate guide edges for each direction of movement of the laying, on which the thread can be guided alternately.
  • the invention has the particular advantage that the stroke reversal of the thread guide can take place independently of the stroke reversal of the thread.
  • the thread is guided in the directions of movement by separate guide edges on the thread guide, which interact with the thread guide.
  • the thread 9 thus leads along the thread guide and is shifted by the respective leading edge of the thread guide. A fixation of the thread within the thread guide no longer takes place. The thread can thus be guided freely.
  • the development of the invention is preferably carried out in which the thread guide is designed to be pivotable on a carrier held on the belt in such a way that the guide edges of the thread guide are at ei ner stroke reversal relative to the thread guide move in the opposite direction, the leading edge guiding the thread dips into the thread guide and releases the thread.
  • the inertia on the thread guide can advantageously be used during the braking phase of the thread guide in order to obtain a pivoting of the thread guide for submerging the guide edge on the thread guide ruler that guides the thread. This allows the thread to be released from the guide.
  • the thread Due to the tension of the thread directed towards the center of the bobbin, the thread can be automatically reversed in its direction of movement after it has been released. The thread thus executes a very rapid reversal that is independent of the reversal of the stroke of the thread guide.
  • the thread guide has a sliding edge on an upper side, which extends between the guide edges formed on the side of the thread guide. There is thus the possibility that the thread is guided along the sliding edge of the thread guide to the opposite guide edge, which is due to the pivoting movement the thread guide extends above the thread guide and takes the thread for guidance.
  • a stripping ramp is assigned to the thread guide ruler in the region of the stroke reversal of the thread guide, through which the thread can be guided in the stroke reversal on the thread guide. This allows the thread to be stripped off the leading edge of the thread guide so that the opposite guide edge on the thread guide takes over and guides the thread after the direction is reversed.
  • controllable actuators are assigned to change the positions of the Ab grazing ramps. In this way, predefined stroke changes of the relocation stroke can be carried out.
  • the belt is given before given by several guide rollers and a drive wheel, wherein the drive wheel is coupled to a stepping motor.
  • the thread guide can be controlled in an oscillating manner within one laying stroke at different laying speeds.

  • FIG. 2 schematically shows a top view of the exemplary embodiment from FIG. 1

  • the thread guide 3 extends essentially parallel to the belt 2.1 and cooperates with the thread guide 1 to lay a thread.
  • the thread guide 1 has a guide edge 1.1 and 1.2 on each of two opposite sides.
  • the Fpoundkan th 1.1 and 1.2 of the thread guide 1 are aligned transversely to the thread guide 3 and protrude on an upper side of the thread guide 3 out.
  • a thread guided with contact on the thread guide ruler 3 is displaced by the guide edges 1.1 and 1.2 along the thread guide ruler 3.
  • the thread guide 1 thus has separate guide edges 1.1 and 1.2 for each direction of movement of the laying of the thread.
  • the guide edge 1.1 acts when the thread guide 1 moves to the left and the guide edge 1.2 when the thread guide 1 moves to the right.
  • the thread guide 3 is assigned several from grazing ramps 4.1 and 4.2.

  • the thread 8 is moved high as the movement of the Fadencle rers 1 on the leading edge 1.1 until the thread 8 has reached the free end of the Fa denrise 1.
  • the thread 8 is automatically reversed in its direction of movement by the thread tension forces directed towards a bobbin center. Independently of this, the thread guide 1 is braked by the belt 2.1 and accelerated in the opposite direction. This situation is shown in Fig. 3.2.
  • the thread 8 is detected by the guide edge 1.2 and guided along the thread guide 3 in the opposite direction.
