Definitions

  • the invention relates to methods and devices for the pneumatic detachment of a broken thread end from the winding cone of a thread winding body in the region of a ring bank of a spinning machine by at least one thread end blow-off nozzle.
  • the thread end blow-off nozzle is arranged in a position below the ring bank, from which this nozzle can coat the conical winding of the thread winding body to be supplied and can detach the thread end from the winding.
  • the thread application device e.g. due to increasing thread breaks, his work is delayed, so that some defective spinning positions on the spinning machine remain unused for a certain time.
  • the ring bank is switched on in the interest of the specified cop construction, i.e. raised.
  • the object of the present invention is to ensure in a simple manner that the thread-end blow-off nozzle is always in a position below the ring bank, from which this nozzle can coat the cone of turns of the thread winding body to be supplied in the desired manner and thus the end of the thread the winding can come off.
  • This object is achieved according to the invention by activating the nozzle as a function of the position of the winding cone. This has the advantage that the efficiency of the thread application device for the automatic removal of thread breaks ver is improved when the thread-end blow-off nozzle is always in the correct position and is thus able to detach the thread end even when the ring rail has left the winding area of the cop.
  • the position of the nozzle can be varied with respect to its position in relation to the winding cone, the nozzle preferably being lowered from its initial position. This lowering can take place, for example, step by step until the thread is gripped.
  • a simple embodiment of the invention results from the fact that a vertically arranged threaded spindle connected to a drive is used, on which a threaded nut holding the nozzle is guided.
  • the drive can preferably be connected to a control device, which in turn is connected to an actuating element for the nozzle and to a thread sensor in the area of a suction bell known per se.
  • the sensory device can have a plurality of sensors arranged one above the other and can be connected to the nozzle or nozzles via a control device.
  • At least one further blowing nozzle directed against the upper end region of the head sleeve is arranged above the ring rail.
  • the blow jet of this nozzle supports the weak blow jet of the thread-end blow-off nozzle at this point and conveys further around the end region of the sleeve thread loops into the effective range of a suction bell.
  • a number of sleeves 2 are arranged on spindles on a spindle bench 1 of a ring spinning machine, with two thread winding bodies 3 being located on these sleeves, each of which has a winding cone 4 in the upper area, i.e. in the area of a ring bench 5.
  • a blow jet B of a thread end blow-off nozzle 6 acts on this winding cone 4 of the thread winding body 3, specifically when a thread breakage has occurred and the corresponding thread end is to be detached from the winding cone 4.
  • the nozzle 6 is fastened on a threaded nut 10 which is arranged on a threaded spindle 9.
  • This threaded spindle 9 is connected to a drive 11.
  • This nozzle 6 is in turn connected to an air source 15 via a valve 24.
  • the valve 24 is controlled by an actuating element 13.
  • Above the thread winding body 3 there is a suction bell 19 known per se with a thread sensor 14 also known per se.
  • the thread sensor 14, the actuating element 13 and the drive 11 for the threaded spindle 9 are each connected to a control device 12 via lines 16, 17 and 18 .
  • control device 12 can receive its triggering command via the line 18 from the thread sensor 14 of the suction cup 19, this control device in turn controlling the drive 11 of the threaded spindle 9 and the actuating device 13 for the air supply to the thread-end blow-off nozzle 6 via the lines 16 and 17.
  • the control device 12 controls the height position of the blowing nozzle 6 in dependence on the height position of the ring bank 5 given to it by the machine control via the input 25 such that the blowing nozzle 6 is at the beginning of the blowing close to the winding cone located there under normal circumstances.
  • a blast air jet B is then triggered by actuating the valve.
  • the nozzle 6 can be lowered from its starting position until the thread sensor 14 feels a thread.
  • the nozzle is gradually lowered until the thread is gripped.
  • a plurality of nozzles 6, 6 ', 6 ⁇ are arranged at different heights, which, starting from the top, can be activated one after the other.
  • Each of these nozzles 6, 6 ', 6 ⁇ is connected to a corresponding valve and an actuating device 13, 13' and 13 ⁇ , which in turn are connected via lines 17, 17 'and 17 ⁇ with a control device 12'.
  • the three, one above the other nozzles 6, 6 ', 6 ⁇ are connected to an air source 15 via corresponding lines.
  • the nozzles 6, 6 ', 6 ⁇ are tracked by means not shown in detail of the movement of the ring rail 5, so that the uppermost nozzle 6 is always in the position in which it can optimally act on the winding cone 4 lying in its expected position. If here in a reasonable time after switching on the blast heater B from the nozzle 6 of the thread sensor 14 feels no thread, the control device 12 'closes the nozzle 6 and opens the nozzle 6'. For this purpose, the control device has a time measuring element. If the thread sensor 14 does not feel a thread in the tube adjoining the funnel 19 even within a reasonable time after switching on the blow heater B from the nozzle 6 ', the control device 12' causes the nozzle 6 'to close and the nozzle 6 ⁇ to open. If no thread is felt here after a reasonable time, it can be assumed that the thread end cannot be found.
  • a sensory device 8 with three sensors 7, 7 'and 7 ⁇ is used.
  • This sensory device 8 is connected via a line 20 to a control device 12 ', which in turn, analogously to the design according to FIG. 1, via line 16 with the drive 11 for the threaded spindle 9 and via line 17 with the actuating element 13 for control the air from the air source 15 communicates.
  • the sensors 7, 7 'and 7 ⁇ detect the position of the winding cone 4 and accordingly control the height position of the nozzle 6, which can be changed in its height position via the drive 11 and the threaded nut 10 and the threaded spindle 9.
  • the sensor device 8 is connected via a control device 12 'analogous to the design according to FIG. 2 with a plurality of nozzles 6, 6', 6 'arranged one above the other and activated in the functional sense according to the position of the winding cone 4.
  • FIGS. 4 and 5 show a further embodiment of the invention.
  • the air speed and thus the intensity of blowing jets decreases with increasing distance from the nozzle outlet and, in the present case, the blowing action is also reduced by the spinning ring 23, which the blowing jet has to penetrate, in a region far below the spinning ring by the winding cone 4 Detached thread end not always safely transported to the suction cup 19.
  • an additional blowing nozzle 22 is arranged according to the invention above the spinning ring 23. This additional nozzle 22 detects a thread end detached by one of the nozzles 6, 6 ', 6 ⁇ and transports it further into the effective range of the suction bell 19.
  • this additional nozzle 22 loops of thread which sometimes wrap around the upper end region of the sleeve 22 and prevent the thread end from being gripped, are blown off and guided into the effective area of the suction bell 19.
  • This additional nozzle 22 is particularly effective when the effective blowing nozzle 6, 6 'or 6' is far below the spinning ring and the effect of its blowing jet in the area of the spinning ring has already waned considerably.
  • the effect of the additional nozzle 22 can be supported and reinforced in a further embodiment of the invention by an air baffle 21.
  • the additional nozzle 22 can be operated simultaneously with one of the nozzles 6, 6 ', 6 ⁇ or staggered in time after this. Your blow jet is directed like that of the nozzles 6, 6 ', 6 ⁇ at an acute angle against the axis of the sleeve 2.
