Definitions

  • the invention relates to a device for receiving a draw roll assembly in a draw or spin-draw winder.
  • the filaments are taken over by manually operated so-called suction pistols and brought onto the stretch reel units 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 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 assembly is guided on rails and can be moved along these rails from a stop determining an operating position into a filament take-over position.
  • Another advantage is the possibility of controlling the displacement speed of the stretching roller unit by means so 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 ', which is known per se, and additionally a deflection roller 7 or 7', which is known per se, on which each multifilament is guided individually in a manner known per se.
  • the first stretching roller assembly 3 is fixedly arranged on a support frame 8, while the second stretching roller assembly 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 through it 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 to it, 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).
  • a compressed air source 26 feeds via a compressed air line 27, in which a pressure reducing valve 28 is installed, a compressed air line 29, respectively. 29 ', for feeding the cylinder 21 for the upward movement of the counterweight 16 and a compressed air line 30, respectively. 30 ', for feeding the cylinders 21 for the downward movement of the counterweight 16.
  • 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 b1 and b2 and a limit switch b3 which signals the lower end position of the counterweight 16.
  • the stretching roller unit 4 In the operating position of the stretching roller assembly 4, i.e. in the starting position of the control, the stretching roller unit 4 is in the upper end position at the stops 25, i.e. the counterweight 16 is in the lower position shown in FIGS. 1, 2 and 4.
  • a relay d2 (FIG. 5) is activated, the associated relay contacts d2 'and d2 "are closed, and the solenoid coil s2 of the valve 32 is activated and thereby the valve 32 in the open position, so that the cylinder 21 via the pressure line 30
  • 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 unit 4 in the lower end position, i.e. are brought up to the support on the support plate 10, the pulse switch b1 (FIG. 4) is actuated manually, so that the switch contacts b1 '(FIG. 5) are closed and the switch contacts b1 "are opened.
  • 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 d1 is de-energized and thus on the one hand interrupts the self-holding function for the relay d1 given by the relay contact d1', and by opening the relay contact d1 "this 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 assembly 4 is covered with an attached heat protection box 36, which has a connecting shaft 37 on its upper wall, which covers the godet 6, into which, in the operating position of the stretching roller assembly 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 assembly 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.
