Definitions

  • the invention relates to a device for guiding, cutting and winding of a continuously running thread when changing the bobbin in one Winding device according to the preamble of claim 1 and a Process for guiding and cutting a continuously running thread according to the preamble of claim 11.
  • a crimped thread is continuously closed a coil wound. After the bobbin has finished winding, a Reel change. For this it is necessary that the thread is cut first is so that the full bobbin with loose thread end against a new empty tube can be changed. The thread end of the continuously tapering thread during the change by means of a pneumatic suction device recorded and discharged. After the bobbin has been changed, the Thread caught by a catcher and on the new tube wrapped up.
  • the known device and the known method have the disadvantage that at the end of the winding cycle, the loose thread end on the finished bobbin is undefined, which is particularly important when it comes to further processing of the loose thread end difficult.
  • the deflection of the thread leads through the transfer device to catch the thread in significant wraps in relation to the Winding tension leads to greater fluctuations in tensile force in the thread. Such fluctuations in tensile force can occur with upstream conveying elements lead to a winder formation.
  • Another object of the invention is to cut after the thread ensure that the loose thread end on a binding bead of the full bobbin is present, and that the running thread to a new one without substantial folding Sleeve is applied.
  • the invention is characterized in that the thread guide and Suction device at the beginning of the bobbin change within the bobbin area are arranged.
  • the winding area is the area on the tube that of the covered thread is covered. This allows the thread to be relatively low Deflection cut and taken over by the thread suction, so that there are no significant fluctuations in thread tension during the change phase occur.
  • the suction device is preferably arranged stationary. At one designed to be movable essentially parallel to the coil Suction device there is the possibility of the loose thread end with the The binding bead is closed at any position within the winding area place.
  • the Driving roller or the necks on the circumference a thread guide groove before the new sleeve for drive is brought into peripheral contact with the drive roller, the thread is guided by the thread guide, the thread guide groove and the Suction device guided.
  • the thread can be folded up without folding transferred from the full spool to a new tube. Through the thread receiving suction device is an undisturbed thread run in the Winding device upstream devices in the change phase guaranteed.
  • the thread guide groove can be on the circumference of the drive roller or be formed radially circumferential on the circumference of the sleeve, so that the thread is safely guided without jamming while the sleeve is accelerating.
  • Thread guide groove of the drive roller in the section of the circumference of the Drive roller or the sleeve formed, which is contacted by the wound coil becomes. This allows the deflections and deflections of the thread during the alternating phase and thus minimize the thread tension fluctuations.
  • the thread guide groove is formed in the necks, the thread guide groove is advantageously placed in the area of the sleeve by the spooled thread is overwrapped.
  • Thread guide groove executed with a groove depth T, which is at least larger than that Thread diameter.
  • the thread guide groove has a groove width B that is much larger than the groove depth.
  • the Thread guide groove formed such that the groove depth T is greater than that Groove width B.
  • This narrow thread guide groove ensures that the thread is held securely in the Thread guide groove held, and also the bobbin build remains during the Unwrapped travel. So that the thread gets into the narrow groove, the Traversing thread guide the thread slowly with reduced Guide the traversing speed over the groove.
  • the thread guide, the thread guide groove on the circumference of the Driving roller and the suction device arranged in a transfer plane.
  • the thread can first be placed on the full bobbin as a binding wrap and Hand over to the suction device without any major deflection.
  • the cutting device of the suction device are introduced.
  • the gripper arm of the Transfer device detects the thread in the thread path between the already lifted bobbin and the thread guide.
  • the transfer plane is preferably designed as the normal plane of the coil and contains the binding coil of the coil. In this normal plane is on the Driving roller provided the thread guide groove. However, it is also possible that Form the thread guide groove at an angle to the axis of the drive roller. This gives the Thread a wobble motion that turns into one when the binding wrap is wrapped leads to improved cohesion of the thread layers.
  • the thread guide is preferably designed with a drive that the thread guide in the longitudinal direction parallel to the sleeve and the movement of the thread guide regardless of direction with variable speed executes.
  • the drive could be a linear drive, for example be executed.
  • the Traversing thread guide the thread outside and inside the winding area Run lengthways parallel to the sleeve.
  • the actual winding travel i.e. winding the spool.
  • the thread from the Suction device taken over.
  • the thread leading remains Traversing thread guide stand on a transfer level.
  • the full coil wound a binding bead the full coil already from the Driving roller is lifted ..
  • the transfer device then leads the thread in the suction device. Now that the bobbin is changed and the Empty sleeve in the bobbin holder between the clamping plates begins the threading. Before the new sleeve is placed on the drive roller, the traversing thread guide and the thread guide groove of the drive roller guide the Thread between the sleeve and the drive roller.
  • the sleeve is on the drive roller attached and accelerated to a speed required for the application.
  • the drive of the traversing thread guide activated, and the traversing thread guide leads the thread into a catch position, in which the thread runs obliquely over a catching plane of the catching device, for example an end edge of the clamping plate.
  • the inventive method is particularly characterized by fast and precise bobbin changes.
  • the thread can be positioned very precisely, so that the thread is secure and without significant slack during the Spool change performed and caught by the safety gear.
