Definitions

  • the invention relates to a device for clamping a Unterwindefadens on a spindle of a ring spinning machine, the spindle below a attached cop a fixed clamping ring and one by means of a Actuator axially displaceable to the spindle, with the clamping ring in Has effective clamping connection bringable ferrule and wherein the Clamping surfaces on the clamping ring and clamping sleeve are conically interlocking. It is preferably provided that the underwind thread with less than 360 ° wraps around and that the actuator is fixed to the Ring spinning machine is arranged.
  • the present invention has for its object the operational safety, in particular to improve the clamping effect of such clamping active connections.
  • the object is achieved in that the clamping surface of the Clamping ring and / or the clamping surface of the clamping sleeve by structuring get higher coefficient of friction.
  • the structuring can be, for example, groove-shaped, be toothed, serrated or meandering. In some cases, the can be achieved.
  • the structuring can be carried out on both or only on one of the interacting clamping elements can be arranged.
  • An advantageous development of the invention provides for the structuring of To form the clamping sleeve and clamping ring each interlocking and clamping sleeve and the clamping ring must be arranged so that they cannot rotate relative to one another.
  • At least one element of the Clamping device is designed to be elastic and that clamping sleeve and clamping ring are held in the clamped position by spring action.
  • the spinning spindle 1 consists of a lower spindle part 2, the is fastened in a spindle bank 3 containing the drive of the spinning spindle and in which the rotatable upper spindle part 4 is mounted.
  • a spindle bank 3 containing the drive of the spinning spindle and in which the rotatable upper spindle part 4 is mounted.
  • On this upper spindle part 4 is a Inserted sleeve 5, on which an incoming thread 6 to a winding 7 is wound up.
  • Sleeve 5 and winding 7 form the cop 8.
  • the thread fed 6 is guided by a ring traveler 9, which rotates on a spinning ring 10, the is in turn arranged in an up and down movable ring bench 11.
  • this includes Clamping device 12 a sleeve 13 fastened on the upper spindle part 4.
  • On this Bushing 13 is by means of screws 14 on a shoulder 15 of the bushing supporting clamping ring 16 held easily replaceable, the outer circumference a portion is frustoconical.
  • Cutting knife 17 can be attached with a sharp cutting edge 18.
  • a clamping sleeve 19 is also axially displaceable, which by means of a on shoulders on the sleeve and in the clamping sleeve supporting spring 20 after is pressed against the clamping ring 16 above.
  • the top inner edge of this Clamping sleeve 19 is adapted to the frustoconical area of the clamping ring 16 frustoconical.
  • the two facing each other frustoconical surfaces 21 and 22 of the clamping ring 16 and the clamping sleeve 19 cooperatively form the clamping device 12 in which the thread 6 is clamped and can be held.
  • the screws 14 also penetrate an inner collar of the Clamping sleeve 19 and secure it against twisting.
  • the clamping sleeve 19 has an outer collar 23 on which it is actuated can be moved downward against the force of the spring 20. How 1 can be seen, this actuator from a along the Spindle bank 3 extending shaft 24, on which a cam 25 is arranged, by means of which by rotating the shaft on the clamping sleeve 19 one in the drawing force can only be exerted by arrows A.
  • the spinning spindle runs out 1, the clamping sleeve 19 by exercising the indicated by the arrows A. Force pressed down. As a result, the frustoconical surfaces 21 and 22 of the clamping ring 16 and the clamping sleeve 19 moved apart and the Clamping device 12 opened. About half to three quarters of the last Rotation of the spinning spindle 1, the ring bench 11 is further guided downwards so far that the thread 6 through the ring traveler 9 with a corresponding circumferential angle the surface 21 of the clamping ring 16 is deposited. After the spinning spindle has come to a complete standstill, is indicated by the arrows A. Force removed so that the spring 20 move the ferrule 19 up and create the surface 22 of the clamping sleeve on the surface 21 of the clamping ring 16, the Clamping device 12 can therefore close. The thread 6 in this Clamping device 12 held.
  • the surfaces 21 and / or 22 of the clamping ring 16 or the clamping sleeve 19 Structuring on.
  • This can consist of a corrugation, its wave crests and Wave valleys alternately interlock and lie on lines that line the axis of the Cut the spindle or the tips of the imaginary cones of these surfaces.
  • the Screws 14 prevent mutual rotation of the clamping ring 16 and Clamping sleeve 19, so that the engagement of the crests and troughs upright
  • the structuring can, for example, also be made from a sharp-edged one Serration or serration of the surfaces 21, 22 exist.
  • an anti-rotation device can be used to be dispensed with.
  • roughening these surfaces is sufficient to achieve the desired to achieve a secure clamping effect.
  • Such roughening can, for example, by Sandblasting can be achieved and lead to a structuring, for example Nail file resembles.
  • one of the clamping elements 16, 19 is elastic, for example made of flexible plastic is formed, it can be structured in another clamping element insert without having to have a structure itself. In this case too there is no need for an anti-rotation device.
