Definitions

  • the invention relates to a winding device for winding a incoming thread according to the preamble of claim 1 and a method for placing a continuously running thread in a Winding device according to the preamble of claim 12.
  • the winding device and the method for applying are from EP 0 916 610 (Bag. 2621).
  • the winding device known from EP 0 916 610 therefore provides that a Clamping gap between a centering shoulder of the clamping plate and the sleeve end is formed. This ensures when the sleeve is released that at the same time the loose thread end is released from the clamp.
  • the object is achieved by a winding device with the Features according to claim 1 and by a method with the features according to Claim 12 solved.
  • the invention is characterized in that the clamping of the thread only during the winding of the spool.
  • the clamping gap is through formed a movable clamp body which is connected to the clamping plate.
  • the clamping gap thus has at least one movable flank through which the Clamping of the thread can be influenced.
  • the clamp body is when the Clamping plate by a centrifugal force in a clamping position for clamping the Thread. This is based on the knowledge that the sleeve and thus the tension plate when threading at high speed through the Driving roller to be driven. In this state, the clamp body is through the centrifugal force acting on the clamping body in a clamping position held in which the clamping gap for clamping the thread is formed.
  • the bobbin holder When changing the bobbin, the bobbin holder is in a change position pivoted, the clamping plate and thus the coil to a standstill be slowed down. As soon as the coil stops, the clamping body is no longer burdened by centrifugal force. The clamping body is released from the Clamping position and can be moved back into a relief position. So that will immediately before or during standstill the thread is released, so that the spool is ready to change.
  • Another advantage of the invention lies in that the loose thread start of the bobbin is a defined and always has constant free length, which are kept particularly short can.
  • the configuration of the winding device is according to claim 2 preferred to clamp the thread directly on the tensioning plate.
  • the The contact surface of the clamping plate forms the clamping position of the Sprag.
  • the clamping gap is due to the shape of the contact surface and determined by the shape of the clamp body. So there is the possibility for example an acute-angled clamping gap or an obtuse-angled one To form a clamping gap with a fixed flank and a movable flank, in which the thread is inserted.
  • a spring acting on the clamping body is provided, one for centrifugal force opposite spring force is generated.
  • the spring force is smaller than that Centrifugal force, so that the clamping body with the rotation of the clamping plate Winding speed defies spring force in the clamping position.
  • the clamping body is preferred by guided a guideway such that the clamping body in the radial direction the internal relief position to the external clamping position is moved.
  • the Catcher a catch and a catch slot on the sleeve facing end face of the clamping plate are introduced.
  • the nip is on End of the catch slot formed so that the catch and that clamping of the Thread within an angle of rotation of less than 180 °, preferably less than 90 °, is possible.
  • the catch slot with its end the contact surface of the clamping body at least partially penetrated. This is the on a leading edge of the catch slot along sliding thread directly into the adjacent nip.
  • the formation of the winding device according to the invention according to claim 10 is particularly characterized in that the thread and the tension plate at Catches are moving in the same direction. With that, essentially Thread running diagonally over the front edge of the tensioning plate immediately after Immerse the catch in the catch slot. Climbing out the Thread from the catch slot is not closed due to the movement in the same direction expect. The thread is caught with a high degree of certainty by the catch nose.
  • the inventive design of the clamping plate is further achieved that the thread is already in the clamping gap after a partial rotation of the tensioning plate is clamped without the thread guide having to change its position.
  • Clamping plate provided a circumferential thread guide edge.
  • the thread leading edge covers the sleeve end, so that the thread at the transition from Clamping plate is guided to the sleeve directly in a normal plane to the sleeve.
  • Figures 1 and 2 is an embodiment of an inventive Winder shown, such as in a texturing machine is inserted.
  • the winding device according to the invention Winding the thread shown. 2
  • the winding device is after the bobbin change when threading is shown.
  • the following Description applies to both Figures 1 and 2, insofar as not expressly to one the figures are referenced.
  • the winding device has a pivotable bobbin holder 4 which a pivot axis 7 is mounted.
  • the pivot axis 7 is at one Machine frame attached.

  • the suction device 18 has a knife 19 and a suction connection 20.
  • the knife 19 is used for cutting the thread when changing the bobbin, with the incoming thread is led through the suction connection to a yarn container.
  • Fig. 2 the bobbin change is completed and the bobbin holder with a new one Sleeve 2 pivoted back into its operating position.
  • the thread 1 is passed through the thread guide 16 in the direction of the tension plate 5 guided so that the clamping plate 5 with the catching device 8 the running thread 1st can catch.
  • the drive 17 of the thread guide 16 is thereby Control device 15 activates as soon as sensor 9 reaches a predefined speed of the clamping plate 5 signals.
  • the clamping plate has a circumferential end edge 25 which is on the sleeve 2 facing end of the clamping plate 5 is formed.
  • a catch nose 27 and a catch slot 28 are formed by a recess 26.
  • the Catch 27 is undercut by the recess 26 such that the tip of the Catch 27 shows in the direction of rotation of the clamping plate 5.
  • the catch slot 28 has a leading edge 31, which is connected to the front edge 25 and one in Extension of the front edge 25 deflecting guidance of the thread in the Catch slot 28 caused by rotation of the clamping plate.
