Definitions

  • the invention relates to a dishwashing machine for winding a thread running continuously into a bobbin according to the preamble of claim 1.
  • a continuously running thread is wound into a bobbin.
  • the full bobbin and the empty tube are each clamped on a winding spindle, which are cantilevered and rotatably mounted on a winding turret.
  • the full bobbin is pivoted from the winding area into a changing area and the empty tube from the changing area into the winding area by rotating the winding turret.
  • the traversing device consists of a pre-traversing unit and a grooved roller.
  • the grooved roller is arranged directly in front of the bobbin to be wound and is partially wrapped around by the thread, the thread being guided in a thread guide groove for placement on the bobbin.
  • the known thread transfer device therefore guides the thread by means of a thread guide in a spacious loop outside the traversing device. Such large deflections generate correspondingly high thread tensions in the thread. These thread tensions can lead to the thread tearing before the thread has been caught on the empty tube. Accordingly, it is an object of the invention to further develop a winding machine of the type mentioned at the outset in such a way that the thread transfer from the full bobbin to the empty tube is as gentle as possible, so that the thread tension fluctuates as little as possible during the transfer.
  • the winding machine according to the invention is characterized in that the degree of wrap of the thread that the thread assumes during the traversing on the grooved roller is approximately maintained when the thread is turned over.
  • the thread pulling forces generated in the thread by friction when the thread is turned from the full bobbin to the empty tube are thus insignificantly changed compared to the thread pulling forces during the winding travel.
  • the thread deflection device of the winding machine has a guide plate guided parallel to the circumference of the grooved roll and a thread guide that can be positioned parallel to the axis of the winding spindles.
  • the leading edge of the guide plate facing the thread will take over the thread and lift it out of the engagement of the pre-curtain and the grooved roller.
  • the thread guide By means of the thread guide, the thread can now be guided into a catch position in which the thread is caught in a catch slot of the empty tube.
  • the thread transfer device of the winding machine according to the invention can advantageously be used when the thread is first placed on an empty tube and when the thread is turned from a full bobbin to an empty tube.
  • the development of the winding machine according to claim 2 has the advantage that the wrapping of the thread on the grooved roller and the wrapping of the thread on the guide plate are essentially the same.
  • the guide plate serves to cover the grooved roller.
  • the guide plate can be designed such that the area of the grooved roller that is not contacted by the thread is completely covered in the rest position of the guide plate. This reduces the air turbulence generated by the grooved roll, so that the thread can be safely guided in the thread guide groove of the grooved roll during traversing.
  • the direction of movement of the guide plate is identical to the direction of the thread.
  • the thread is first guided out of the pre-traversing unit during the movement of the guide plate, which is particularly advantageous in the case of a grooved roller which has a thread guide groove only in the end regions of the traversing stroke.
  • the configuration of the winding machine according to claim 4 can preferably be used. With this arrangement, the thread is first removed from the engagement of the grooved roller, the thread being able to follow the traversing movement of the pre-traversing unit by sliding along the leading edge of the guide plate without impairment.
  • the particularly advantageous development of the winding machine according to claim 5 is particularly suitable when the thread is turned from a full bobbin to an empty tube.
  • the full bobbin is moved into an outer position on the winding turret by means of the winding spindle, so that the empty tube and the full bobbin are positioned offset to one another in the direction of thread travel. This avoids that while the thread is being guided in the catch position, it does not run off the full spool. Until the thread is caught in a catch slot of the empty tube, the thread is wound on the full spool.
  • this version of the winding machine has a very high contact security. The thread can be guided in a parallel thread run to the catch slot in the empty tube. The entire length of the catch slot is thus available for catching the thread.
  • the configuration of the winding machine according to claim 6 is preferably to be used in order to be able to deposit the thread already guided from the traversing on the full bobbin without forming a binding bead. Only when the full spool is moved to its outer position is a binding bead wound on the full spool.
  • Another advantage of this embodiment is that no additional drive means are required to displace the winding spindle.
  • winding machine provides that the winding turret can be driven with the opposite direction of rotation to the direction of rotation of the winding spindle. This ensures that the empty tube moves in the opposite direction to the thread running during catching.
  • the relative movement between the empty tube and the thread leads to the fact that the empty tube very quickly leads the required clamping forces to build up a thread tension, which causes the tearing of the thread in the section between the empty tube and the full spool.
  • this arrangement allows the wrap around the empty tube required for catching the thread to be kept very low, so that no sudden changes in tension in the thread occur when the empty tube is pivoted into the thread path.
  • the looping of the thread on the empty tube in the winding area can be minimized. Only after the thread has been brought into the catching position is the feed plate pivoted into the thread path between the empty tube and the full spool, so that the leading edge deflects the thread. This sets the looping of the thread on the empty tube required for catching.
  • the design of the winding machine according to claim 10 is particularly advantageous in order to avoid the loose thread end of the full bobbin coming into the area of the bobbin to be newly formed.
  • the swivel direction of the contact plate and the rotational movement of the full spool are aligned in the alternating area. This prevents the loose thread end from hitting the leading edge of the feed plate.

  • the thread 1 is first passed through the head thread guide 2, which forms the tip of the traversing triangle.
  • the thread then arrives at the traversing device 3.

Abstract

L'invention concerne une machine de bobinage pour enrouler un fil, arrivant en continu, en vue de former une bobine, ce fil étant guidé dans un guide-fil va-et-vient et constitué d'un pré-guide-fil et d'un cylindre à gorge placé en aval de la trajectoire du fil. Pour pouvoir réaliser un changement de fil d'une bobine pleine, montée sur une broche de bobinage, à une busette vide, montée sur une autre broche de bobinage, par rotation d'une tourelle de bobinage, cette machine de bobinage possède un système déflecteur de fil. Ce système comporte une tôle de guidage guidée parallèlement à la périphérie du cylindre à gorge et un guide-fil positionnable parallèlement à l'axe par rapport aux broches de bobinage. Le pivotement de la tôle de guidage permet de guider le fil hors du guide-fil va-et-vient sans modification substantielle de l'enroulement.
