Definitions

  • the invention relates to a device for withdrawing a thread, tape or the like from a thread package according to the preamble of claim 1 and a method according to claim 13.
  • DE-PS 16 35 899 shows a generic device in which the thread is drawn off overhead through a draw-off eye of the thread roll.
  • a disadvantage of this thread draw-off device is that the thread twist by 360 ° that occurs after each thread turn is pulled, which forces the thread, band or the like being pulled off a considerable amount of twist.
  • the number of twists depends on the diameter of the thread roll and the length of the thread that has been drawn off. In particular when pulling flat strips, this often leads to the formation of twists of the thread (kinks) and thereby to malfunctions of thread stores downstream of the thread take-off device, for example.
  • the invention is therefore based on the object of improving a thread take-off device in question in such a way that a twist imposed on the drawn-off thread is reduced up to the complete cancellation of the twist.
  • the invention is also based on the object of specifying a method for twist-free thread take-off.
  • a thread take-off device in which the thread can be drawn alternately over one of the two end faces of the thread spool. It is also envisaged that either a pull-off eyelet or the like can be shifted to the other opposite pull-off position after each drawn turn or that the pull-off eyelet be shifted between the two pull-off points after a plurality of pulled turns, optionally also periodically.
  • the thread winding is preferably mounted in a rotationally inhibited manner by a holder.
  • the withdrawal points are opposite each other and form the poles of a bearing axis.
  • a thread winder is mounted from a holder for pulling the thread in such a way that it is aligned approximately parallel to the bearing axis.
  • the thread is then alternately withdrawn from a take-off point above the thread winding.
  • the twist that occurs after deducting a number of turns is at least partially compensated for, if possible canceled, by a twist in the opposite direction of rotation when withdrawn via the opposite end face.
  • the holder of the thread winding preferably consists of a bed that is concave to the bearing axis.
  • the thread winding can lie in this curvature so that it cannot roll out due to the force of gravity and cannot be displaced in the axial direction due to the friction.
  • the bed is preferably designed as a cloth that supports the thread winding in a curvature.
  • the thread is pulled once between the bed and the thread winding when each turn is drawn off.
  • the storage of the thread winder can be made safer in that the bearing bed of several transverse to the longitudinal axis and parallel to each other arranged, convexly formed around the bearing axis bearing ribs.
  • the bearing ribs are formed by narrow, preferably elastic wire spirals or bristles which, curved around the bearing axis, form a trough-shaped grid on which the thread winding rests.
  • Also preferred is an embodiment of the holder in the form of two bearing bars arranged parallel to the bearing axis. The thread wrap is then stored on the top edge of the spar.
  • An advantage of this configuration is, for example, that the thread only ever has to be pulled between one spar and the thread winding, while the thread winding can lie fully on the other. This effectively prevents rotation of the thread wrap.
  • the alternation of the opposite take-off points also has the effect that any axial displacement of the thread winding during thread take-off is balanced out on average.
  • a more uniform removal of the thread from the thread winding can be achieved in that the bearing bars are provided at their upper edges with air outlet nozzles through which air exits to form an air cushion on which the thread winding is suspended.
  • a swivel arm is provided for displacing a trigger eyelet, which swivel arm can be swiveled about a swivel axis arranged perpendicular to the longitudinal axis.
  • the swivel range is preferably approximately 180 °, so that the swivel arm can be shifted from one axial pole position to the opposite pole position and the thread take-off direction is in each case aligned with the direction of extension of the thread spool.
  • Downstream of the thread take-off eyelet is a guide eyelet which is stationary and which is equally spaced from the two opposing stopping points.
  • the guide eye is preferably arranged opposite the pivot axis of a pivot arm.
  • the swivel joint of the swivel arm is preferably arranged below the holder for the thread winding.
  • the thread take-off device shown in FIGS. 1-3 consists of a holder 2 and a swivel arm 9 which can be swiveled about a swivel axis y and which has a draw-off eye 3 at the end.
  • the holder forms a longitudinal axis x, around which the bearing bed formed by a plurality of bearing ribs 5 arranged parallel to one another is concavely curved. In the concave curvature of the Bearing bed 2, as shown, a thread winder 1 can be stored.
  • the cylindrical or conically shaped thread winding 1 lies approximately parallel to the bearing axis x such that its end faces 1 ', 1''are each aligned with the poles of the bearing axis x.
  • the central axis of a conically shaped thread winding can also intersect the bearing axis x.
  • the bearing ribs 5 are formed as wire spirals, so that a rotational movement of the thread winding is inhibited by friction.
  • the wire turns are so close together that jamming of the thread is avoided.
  • the swivel joint of the swivel arm 9 which can be swiveled about the swivel axis y is arranged below the bearing bed 2 in such a way that the swivel axis y intersects the x-axis.
  • the pivot arm 9 can be pivoted from a position A, which corresponds to one pole of the bearing axis x, by 180 °, so that it assumes an opposite trigger position B, which corresponds to the other pole of the bearing axis.
  • the thread is pulled through the draw-off eye 3.
  • a fixed guide eyelet 10 is arranged above the bed in equidistant distance from the draw-off points A, B and is arranged downstream of the draw-off eyelet 3.
  • FIGS. 4 and 5 Another embodiment of the invention is shown in FIGS. 4 and 5.
  • the holder 2 is formed by two bearing bars 6, 7 running parallel to the bearing axis x.
  • the thread spool 1 rests on the upper edges of the two bearing spars 6, 7, so that a thread 4 initially pulls over one of the two stiffening surfaces 1 ', 1'' is pulled between the one spar 6 and the thread winding 1 while the thread winding 1 rests on the other spar 7. This increases the storage stability of the thread package on the holder.
  • the bearing bars 6, 7 have air outlet nozzles 8 at their upper edges, from which air can escape in the direction of the surface of the thread bobbin 1.
  • the air jet emerging from the air outlet nozzles 8 then lifts the thread winding 1 on the bearing rail, so that the thread 4 can be pulled off without friction.
  • a conical thread wrap 1 lies in a made of a cloth, which can be a fabric.
  • the holder 2 formed by the cloth forms a curvature for the rotationally inhibited mounting of the thread winding 1.
