Definitions

  • the invention relates to a yarn feeder with two feeder rollers, of which the one role is resilient against the other role, one of the two roles is floating so that it is able to swivel or pendulum movements to perform relative to the other role.
  • yarn feeders at least one of the two rollers is driven in rotation from the outside, while the other non-externally driven roller from that conveyed through the roller nip Thread is set in rotation.
  • the two roles are aligned parallel to each other, one of the two rollers for inserting a thread into the delivery plant usually away from the other role either translationally or pivotally moved and can be adjusted to the other reel after inserting the thread.
  • the distance between the two rollers essentially by the thread thickness of the passing thread determined, this distance ideally over the entire Roll length should be constant.
  • the present invention is based on the problem that arises when two threads with different thicknesses or titers at the same time with the supplier a machine, for example for the production of fancy yarn should, since then the roller gap adjusts to the thickness of the thicker thread and so that the thinner thread remains unaffected by the rolls.
  • this known delivery mechanism is able to solve the problem described above while simultaneously promoting two To solve threads, even if the goal is to improve the parallelism of the axes between the two rollers. solve, even if the aim of this known delivery system is to improve the axis parallelism between the two rollers.
  • the disadvantage of the known delivery system is that a relatively large system is suspended from the pivot point, namely in addition to the role also the swing arm carrying this role and also spring-loaded.
  • the invention is based on the object, a simplified thread delivery mechanism to provide for the simultaneous supply of two threads, with which independently of different thicknesses or titers of the two threads or of occurring Thread thickening or thread constriction in any case an even slip-free conveyance of both threads or thread sections is guaranteed.
  • the yarn feed mechanism according to the invention is characterized in that that the floating roller as a rotationally symmetrical hollow body is formed, with its inner wall on a fixed on an axle shaft, spherical support body is formed such that the position of the floating stored role only in a plane determined by the axes of the two roles is changeable.
  • the support body mounted on the in particular stationary axle shaft preferably has the shape of a ball.
  • the thread feed mechanism is characterized according to a preferred embodiment by abutting against the floating roller, the parallel to the plane through the axes of the two rollers on the one hand and perpendicular on the other hand are aligned with the roll gap of the supplying plant.
  • the thread feed unit consists of two delivery unit rolls 1 and 2, of which the delivery roller 1 is mounted on a spring-loaded swivel arm 10, so that they are pivoted away from the delivery roller 2 for inserting the threads A and B. and can be put back on the reel 2 after inserting the threads.
  • On the swivel arm 10 is, for. B. attached a tension spring 11 with one end while the other end of this tension spring 11 on a stationary (not shown) Part z. B. the thread feeder or the machine frame is attached.
  • the roller 2 is designed as a hollow body, with its inner wall on a spherical support body attached to a stationary axle shaft 11 12, preferably in spherical form, is supported.
  • a stationary axle shaft 11 12 preferably in spherical form
  • the roller 2 stopper bodies 13, 14 which are parallel to the plane defined by the axes of the two rollers 1, 2 on the one hand and vertically on the other hand are aligned with the roll gap of the supplying plant.
  • roller 2 change its position only around an axis in one plane can, which is determined by the axis of the two rollers, while by the counter the top of the roller 2 abutting stop body 13, 14 a pivoting or Tilting of the roller 2 around a horizontal axis in a plane is prevented tangential to the lateral surfaces of the contacting in the area of the roller gap two roles 1, 2 is placed.
  • the roll 2 is able, according to the thread thickening or to avoid thread constriction, so that the roller 2 relative to the roller 1 according to the thickening or constriction.
  • the nip is thus larger or smaller in the area of the thread section A, while in the area of the Thread section B of the roller gap its original size according to the thread thickness this thread section B retains. In this way it is ensured that the on both thread sections A and B from the rollers 1 and 2 applied pressing forces remain constant, which ensures even and slip-free conveyance of both thread sections A and B is guaranteed by the supplier.
  • one of the two roles can be used by one also attached to the pivot arm 10 motor 12 are driven.
  • a drive As can be seen from FIG. 2, both roles can also take place in such a way that a tensile force is exerted on one of the two thread sections A or B, whereby both rollers 1 and 2 are driven in rotation and the other Thread section is promoted accordingly.
