Definitions

  • the invention relates to a winding device for winding a continuously tapering thread according to the preamble of claim 1 and a method for applying a continuously tapering thread a driven sleeve according to the preamble of claim 13.
  • EP 0 477 787 (Bag. 1845) describes the method and a method Generic winding device known, in which a continuous incoming thread is applied to a driven sleeve.
  • the sleeve is clamped between two clamping plates.
  • the clamping plate are rotatably attached to a spool holder.
  • the clamping plates each have a centering shoulder, which is conical is formed and protrudes into the end of the sleeve. So that is the sleeve centered.
  • the continuously tapering thread discharged by means of a suction device.
  • a thread guide is moved with the thread so that the Thread is caught by one of the tension plates. This is in the marginal area the clamping plate has a catch slot with a catch nose that is inclined in the circumferential direction educated. After the thread has been caught by the catch, a Pinching and cutting the thread.
  • the Immerse the thread in the catch slot in such a way that when the tensioning plate rotates the thread gets under the catch nose.
  • the invention is characterized in that the thread and the tension plate are aligned in their movement when caught. So that in thread running diagonally across the front edge of the tensioning plate Immerse into the catch slot immediately after reaching the catch nose. On Climbing out the thread from the catch slot is due to the rectified No movement expected. The thread is with high certainty from the Captured nose.
  • the inventive design of the clamping plate is further achieved that the thread already after a partial rotation of the Tensioning plate is clamped in the clamping slot without the thread guide changed its position. By trained on the edge of the clamping plate The leading edge is the thread in the section between the catch nose and the Thread guide inserted into the clamping slot when the tensioning plate rotates. As soon as the thread is clamped, the thread guide can move from its position to Forming a thread reserve on the sleeve or for transferring the thread in a traversing thread guide are moved.
  • a particularly preferred development of the winding device according to Claim 2 is characterized in that the thread already with a low deflection and correspondingly small wraps through the Thread guides are guided to the front edge of the tensioning plate for catching can.
  • the thread guide is easy to use, for example to move a linear actuator.
  • the suction device is preferred arranged on the side of the sleeve facing away from the oscillation. In this case, the deflection of the thread can be done as far as possible of the sleeve end arranged suction device can be minimized.
  • the formation of the take-up device according to the invention 3 is characterized in that the jammed when changing the bobbin Thread end between the sleeve edge and the centering shoulder of the tension plate is released directly from the clamping plate when the sleeve is released, thereby Disruptions in the unwinding of the bobbin can be avoided by the thread cannot get stuck on the clamping plate.
  • the loose thread end a defined and always has constant free length.
  • the recess in the centering of the Clamping plates can be designed as a groove, recess or flat his.
  • Winding device is particularly advantageous.
  • the clamping slot between a radially directed steep clamping edge of the Recess and the sleeve edge formed.
  • the clamping edge extends here opposite to the direction of rotation essentially helical on Centering approach from a larger centering diameter to a smaller one Centering diameter. This will counteract the direction of rotation constantly narrowing clamping slot formed.
  • the formation of the winding device according to claim 7 stands out characterized in that the catching of the thread and the pinching of the thread in different levels. This ensures that the thread is secure is held in the catch groove.
  • a stationary cutting device is provided around the winding device To cut thread.
  • the thread in the section between the catch and the suction device by rotating the clamping plate automatically inserted into the cutting device.
  • the cutting device is with a Leading edge and a step formed directly in front of the knife blade executed. This ensures that the thread shortly before hitting the Knife blade receives a movement impulse.
  • the development of the winding device according to claim 10 stands out particularly characterized in that the movement of the thread guide and the position of the catch slot can be coordinated so that the on the one hand the safety of fishing is increased and on the other hand the time during which the thread is deflected, can be shortened considerably.
  • Pulse generator is executed. So that both the location and the Speed of the sleeve can be determined from the pulse train.
  • Determination of the speed of the clamping plate is of particular importance, since after a bobbin change the empty tube first to one for winding required speed must be accelerated. By sensing it is thus possible that the thread immediately after reaching the required Speed of the tension plate by the thread guide to catch on the Front edge of the clamping plate is placed.
  • Winding device has the advantage that none additional control unit required to control the traversing device is. All operations during winding, during bobbin change and during the catch are controlled by a control device Traversing device controlled.
  • the thread After the thread has been caught and wound on the core, the actual coil travel takes place, i.e. winding the spool. After this the bobbin is finished, the thread is used to initiate the bobbin change taken over by the suction device. The thread leading The traversing thread guide remains in a transfer position. After now the bobbin has been changed and the empty tube in the bobbin holder between the tension plates is tensioned, the thread begins to be put on. First. the sleeve is accelerated to a speed required for the application. As soon as the speed is reached, the traversing thread guide is driven activated and the traversing thread guide guides the thread into a catch position, in which the thread runs diagonally over the front edge of the tension plate.
