Definitions

  • the invention relates to a winding device for Threads of V-gates, from the bobbins of which the threads are wrapped by wrapping rods and peeled off and on by a comb a winding tree of the winding device is wound up, the pre-wrap bars near the winder more and less thread loops, and their degree of wrap with adjustable pre-wrap bars is centrally adjustable, being in the running direction of the threads at least one measuring device for determination behind the comb of thread tension is arranged in threads and wherein the central adjustment of the pre-wrapping rods the measurement result is controllable accordingly.
  • the winder pulls the threads from bobbins plugged onto the mandrels of the spool of the creel are. They traditionally have to be braked to the thread tension required for proper winding or to create thread tension.
  • the thread running speeds can, however, become so large that the braking of the threads when removing from the spools is no longer required.
  • the air friction resistance of the thread can be so become large that additional braking is not necessary. This applies in particular to V-gates. The through the air friction resistance however, the thread pull is achieved on the length of the thread between the winding unit and the winding device dependent.
  • the pre-wrapping rods become different thread tensile forces used, in such a way that at the beginning of Gatters a stronger wrapping of the rods through the threads is given, however, a lower one at the end of the gate Wrap. Accordingly, the thread tensile forces are different affected. In particular, the thread tension the threads running from the beginning of the gate increased so that they run into all of the winding device Threads are about the same size.
  • a winding device with the features mentioned above is known from DE-U-9 306 680. With the pre-brake rods it is possible to influence the thread running resistance by wrap these rods relative to each other can be set. However, such an attitude can predominantly not done automatically because of the overall setting or the central adjustment of the pre-wrapping rods can not take into account that the thread tension depending on the end of the gate to the start of the gate different from material and thread speed to change.

  • Vorumschlingungsstangen are summarized in functional groups.
  • the thread tension can each Group can be determined and then a group-wise control respectively.
  • the setting can be automated so that thread groups is braked differently.
  • the Friction of the threads on the pre-wrapping rods accordingly be influenced so that the same or at least about same thread tensile forces can be achieved in the thread groups.
  • the thread tension of the threads coming from the beginning of the gate can pull on the thread tension coming from the end of the gate Threads are better adjusted if their material and Running speeds can be changed. It will be automatic Detection of the thread tension enables, as necessary also stopping the winding process.
  • the functional groups In particular, control also enables adaptation to reach during the winding process, so not only from winding section to winding section.
  • the thread collecting rod brings up all the threads or part of them a predetermined level, which makes it easier when Measuring the tensile forces of several threads contributes. In particular is the constructive effort for the design of the Measuring device lower.
  • the winding device can be designed so that the thread collecting rod is vertically adjustable and one or carries several measuring devices.
  • the adjustability of the thread collecting rod enables adaptation to the respective Thread feed ratios, in particular also the measuring devices be moved accordingly.
  • Individual settings of the measuring devices are not necessary, such as also not special, independent of the thread collecting rod Brackets for the measuring devices. By the adjustment the thread collecting rod can on the measuring range of the measuring device Be considered.
  • the winding device can be equipped with different measuring devices operate.
  • an embodiment is expedient in that the measuring device with a Is provided with a plurality of thread-supporting pressure measuring strips, the ends of which are immersed in the thread sheet Immersion lamella.

Averaging is made possible the error formation that occurs on the thread during a single measurement does not have. On the other hand, the metrological Effort to capture all threads avoided.
  • the control can be carried out in different ways are adapted to the control requirements. It is advantageous to design the winding device so that the central adjustment in the sense of an equality of the measurement results all measuring devices and / or in the sense of predetermined Thread tensile forces are controllable.

That’s enough in a variety of ways Use cases. However, there are also particularly string tension sensitive Threads where not just balancing the Thread tension between the respective groups of quality must be done, but also in terms of quantity, so that the control in the sense of predetermined thread tension is carried out, e.g. So taking into account the given maximum thread tension.
