Definitions

  • the invention relates to a device for receiving a draw roll assembly in a draw-winder or spin-draw winder.
  • the filaments are taken over by manually operated so-called suction pistols and brought onto the stretching roll assemblies or into the winding device by the operator.
  • the multifilament taken over by the suction gun can be delivered either from a spinning shaft or a supply spool. Multifilament is to be understood as a number of summarized endless individual fibrils.
  • the stretching roller units are installed at heights above the ground that do not allow the filament to be laid on without an aid to overcome this height, for example to enable the distribution of several multifilaments on a winding device with small deflection angles or to enable a long stretching zone, it is known that For this purpose, mobile stairs or lifting platforms allow the operator to put on the filament.
  • the invention is therefore based on the object of making it possible to hang up safely without the operator having to use the aids mentioned.
  • the invention achieves the object in that the stretching roller unit is guided on rails and can be moved along these rails from a stop determining an operating position into a filament take-over position.
  • V ER sliding speed of draw roll unit to be controlled by means such that thread breaks can be avoided.
  • a multifilament bundle 2 which comes from a supply spool or a spinning shaft (both not shown) and is composed of four individual multifilaments, is guided in a draw-winder or spin-draw-winder 1 via a first draw-roll unit 3 and then via a second draw-roll unit 4 into a winding unit 5.
  • the stretching roller units 3 and 4 each comprise a godet 6 or 6 'known per se, and in addition each have a known deflection roller 7 or 7 ', on which each multifilament is guided individually in a manner known per se.
  • the first stretching roller unit 3 is fixedly arranged on a support frame 8, while the second stretching roller unit 4 is guided on two guide rods 9 so as to be displaceable in a substantially vertical direction.
  • the lower end of the guide rods 9 is supported on a support plate 10 belonging to the support frame 8, connected to it and fixed at its upper end by a cover plate 11.
  • the cover plate 11 is in turn supported and fixed by supports 12, which are also supported on the support plate 10 and connected to it.
  • a rope 15 is guided over rollers 13 and 14, which is attached at one end to the second stretching roller assembly 4 and at the other end to a counterweight 16.
  • the roller 13 is fixedly arranged on the cover plate 11 by means of a bearing 17, and the roller 14 is rotatably arranged by means of a bearing 18.
  • the counterweight 16 is guided by means of sliding elements 19 attached to it, which bear against rails 20.
  • the rails 20 are supported with their lower end on the support plate 10 and are fastened to it.
  • the rails 20 are fixed at their upper end by the cover plate 11.
  • a yoke 16 ′ attached thereto, which projects beyond the width B of the counterweight 16, and is connected to two pressure cylinders 21.
  • the printing cylinders in turn are connected to the cover plate 11 by means of supports 22.
  • Struts 23 and 24 (only shown in FIG. 2), which are fastened to the support frame 8, respectively to the supports 12, fix the spin-stretch winder 1 either on a wall (not shown) or on a further support structure (not shown).
  • an electropneumatically controlled 3/2-way pneumatic valve 31 respectively. 32, with a so-called blocking zero position, as well as an adjustable throttle check valve 33, respectively. 34, provided. These latter valves are installed such that the ventilation of the lines 29 ', respectively. 30 'is throttled.
  • control system requires an electrical pulse pushbutton switch bl and b2 and a limit switch b3 which signals the lower end position of the counterweight 16.
  • a relay d2 (FIG. 5) is activated, the associated relay contacts d2 'and d2' 'are closed, and the solenoid s2 of the valve 32 is activated and thereby the valve 32 is in the open position, so that the cylinder 21 via the pressure line 30 'are pressurized with compressed air.
  • the pressure line 29 ' is vented via the valve 31 in the open position (FIG. 4) so that the cylinders 21 are not pressurized with compressed air on the piston rod side.
  • the stretching roller assembly 4 in the lower end position, that is, until it rests on the support plate 10, the pulse switch bl (FIG. 4) is actuated manually, so that the switching contacts bl '(FIG. 5) are closed and the switching contacts b1 ".
  • the relay d2 is de-energized and the relay contacts d2 'and d2" are opened, the solenoid s2 is de-energized, and there brought into the zero blocking position by the valve 32, and on the other hand a relay dl is activated, and the relay contacts dl 'and dl "are closed thereby, whereby the solenoid coil sl of the valve 31 is activated and thereby the valve 31 is shifted from the blocking position into the open position
  • the pressure line 30 ' is vented on the one hand and on the other hand the pressure line 29' and thus the cylinders 21 are pressurized with compressed air on the piston rod side.
  • the cylinders 21 now push the weight upwards at a speed throttled by the valve 34.
  • the pistons 21 'of the cylinders 21 are now subjected to the same air pressure on both sides.
  • the downward movement of the weight 16 is therefore throttled in its speed by means of valve 33.
  • the limit switch b3 is actuated by the yoke 16 ', as a result of which the relay dl is de-energized and thus on the one hand interrupts the self-holding function for the relay dl given by the relay contact dl', and by opening the relay contact dl "that Valve 31 is moved back into the blocking zero position. In this position of this valve, the pressure line 29 'is vented and the piston rod side of the cylinder 21 is relieved.
  • the stretching roller assembly 4 is now pressed against the stops 25 with the weight force P G plus the piston force P 2 .
  • the second stretching roller unit 4 is provided with a heat protection box 36 attached to it covers, on its upper wall, which covers the godet 6, has a connecting shaft 37 into which, in the operating position of the stretching roller unit 4, a steam suction nozzle 38 opens tightly.
  • the steam suction nozzle 38 is fastened to the cover plate 11 by means of a resilient support 39 in such a way that, in the operating position of the stretching roller unit 4, the steam suction nozzle 38 with the force of the tensioned support 39 on the inner shaft edges (not particularly marked) of the connecting shaft 37 fits tightly.
  • the steam suction nozzle is in turn connected to a steam suction pipe 40, which is provided in a manner known per se with a flexible pipe part (not shown) so that the steam suction nozzle can follow the movement of the resilient support 39.
