Definitions

  • ABSTRACT The spindle axle is disposed in vertical relation and is suspended at one end via an eye and hook so that the yarn is free to swing in a pendular manner.
  • a damping means is also disposed between the hook and a fixed support point to damp vibrations.
  • the unwinding spindles have been mounted with their spindle axes substantially vertical so that the amplifying influence of the force of gravity is eliminated.
  • the still-present vibrations are caused solely by centrifugal force.
  • the spindle-bearing housing has been mounted in soft rubber.
  • the invention in order to unwind a yarn, such as a set yarn, from a spool of yarn rotatably mounted on a spindle, provides a suspension means for mounting the spindle in vertical disposition from a fixed point with a universal degree of motion to permit the spindle to pendulate during unwinding of the yarn from the spool.
  • This suspension means includes an eye secured to the upper end of an axle of the spindle, which eye has a rim defining an opening, and a hook secured to a fixed point or to a machine frame above the spindle.
  • the hook is disposed in the opening of the eye in pivotal contact with the eye so that the eye can pivot in all directions below the hook under the influence of the spindle motion. in this way, a pendular motion of the unwinding spindle is possible in all directions.
  • the suspension means permits the suspended unwinding spindle and the spool of yarn thereon to form a freely pendulating suspended gyroscope which, during the rotation of its masses, automatically centers itself without being hindered in this effort by the mounting arrangement. To a great extent, this eliminates not only increased stressing of the spindle bearings because of vibrations, but also eliminates a transmission of such vibrations to the machine frame.
  • the suspension means also eliminates troublesome noise.
  • the drawing illustrates a partial cross-sectional view of a suspension means according to the invention supporting an unwinding spindle in vertical disposition.
  • an unwinding spindle 1 has a spindle element 2 in the form of a hollow cylinder, which is mounted by means of two roller-bearings 3 and 4 so as to be able to rotate about and on a spindle axle 5.
  • a spool or roll of yarn 6 is disposed on the spindle element 2.
  • the spool is shown with a nonuniform distribution of mass as indicated by a parallelogram-like outline.
  • Pivoting of the unwinding spindle l in all directions is made possible by the suspension of the upper end of the spindle axle 5, in such a way that the spindle 1 can pendulate freely.
  • a suspension means 7 is provided which consists of an eye 9 fastened to the upper end 8 of the spindle axle 5, and of a hook 10 fastened to a fixed point, in which hook the eye 9 is hung.
  • the fixed point is advantageously disposed on the machine frame of the unwinding machine (not shown).
  • the eye 9 has an inner rim 12 which defines an opening to receive the hook 110.
  • the longitudinal axis of the spindle axle 5 is disposed in the plane of the opening of the eye 9.
  • the inner rim 12 of the eye 9 is advantageously rounded off so that friction can be diminished during pendular motion of the spindle l and, thus, during pivoting of the eye 9 relative to the hook 10.
  • the eye 9 is disposed on a bushing 13, which can be screwed or threaded onto the upper end 8 of the spindle axle 5.
  • the eye 9 can be fastened in a particularly simple way to the spindle axle 5 while at the same time being detachable from the axle 5.
  • the eye 9 and the bushing 13 may be made very simply in one piece and advantageously consist of one piece of synthetic material that, even without lubrication, slides particularly well on the material of the hook 10.
  • the hook 10 can have self-lubricating properties.
  • Polyamide has proved particularly suitable as a synthetic material.
  • a damping means 14 is disposed between the fixed point on the machine frame 11 and the hook M).
  • the invention allows the unwinding spindle 1 to be suspended in a position to make pendular movements in all directions. These pendular movements occur particularlyat starting-up. With increased unwinding speed, a self-centering of the unwinding spindle 1 occurs which practically represents a gyroscope. Vibrations are no longer transmitted to the machine frame .11 so that, practically speaking, no noise occurs. Further, there is less stressing of the roller bearings 3 and 4.
  • suspension means for mounting said axle in vertical disposition from a fixed point with a universal degree of motion to permit said axle and said spool to pendulate during unwinding of the yarn from said spool;
  • said suspension means includes an eye secured to an upper end of said axle with a rim defining an opening and a hook secured to said damping means, said hook being disposed in said opening in pivotal contact with said eye.
  • a damping means supporting said hook in a vertical dependent manner from a fixed point
  • an eye on said axle having a rounded rim defining an opening, said hook passing through said eye opening to suspend said axle and said spool in vertical disposition therefrom, said hook being in pivotal contact with said eye to permit universal pivoting of said eye and axle; said axle having a'longitudinal axis in the plane of said eye opening.
