Definitions

  • the invention relates to a method and a device for the pneumatic detachment of a broken thread end from the 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 which can be activated depending on the position of the cone of turns.
  • Such a device is known from DE 36 00 916 A.
  • the area in which the thread end blow-off nozzle is activated is assigned to the position of the ring bank insofar as the thread end blow-off nozzle is always guided close under the ring bank before it is activated. It is assumed that the winding cone, on which the end of the broken thread lies, is in the winding area that the ring rail is currently covering.
  • the object of the present invention is accordingly to ensure in a simple manner that the position of the thread-end blow-off nozzle and thus its range of action is relocated in such a way that it brushes the winding cone of the thread winding body to be supplied irrespective of its current position and thus can detach the thread end from the winding.
  • the position of a single thread end blow-off nozzle can be varied with respect to its position in relation to the winding cone. If - as is usually the case - the ring bank is advanced upwards, the nozzle can be lowered from its starting position. This lowering can take place gradually until the thread is gripped.
  • a plurality of blow-off nozzles arranged one above the other can be activated in succession.
  • a sensory device which determines the position of the winding cone of the thread winding body, with which the position of an individual thread end blowing nozzle is controlled or the successive activation in the relevant position is effected by a plurality of thread end blowing nozzles.
  • At least one further blowing nozzle which is arranged above the ring rail and directed against the upper end region of the sleeve of the thread winding body, has proven to be particularly advantageous.
  • the blowing jet of this nozzle supports the only weak blowing jet of the thread-end blow-off nozzle at this point and possibly conveys thread loops around the end region of the sleeve into the effective area of a suction bell.
  • a number of sleeves 2 are arranged above 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.
  • 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 .
  • the control device 12 can receive its trigger 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 so 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 can be activated one after the other, starting from the top.
  • 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 ⁇ to 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 in a reasonable time after switching on the blower B from the nozzle 6 ', the control device 12' causes the nozzle 6 'to close and the nozzle 6 ⁇ to open. If here too no thread is felt after a reasonable time, it can be assumed that the end of the thread 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.
  • this additional nozzle 22 loops of thread which sometimes wrap around the upper end region of the sleeve 22 and prevent the end of the thread 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 decreased considerably.
  • it is also advantageous regardless of the use of height-adjustable or height-offset blowing nozzles if there is a considerable distance between the winding cone 4 and the upper end of the sleeve 2, that is to say if the winding cone is still in the lower region of the sleeve at the start of the withdrawal or if very long sleeves are used be used. It has been shown that in this case detached thread ends loop around the upper region of the sleeve and do not get into the suction nozzle 19.
  • 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 just like that of the nozzles 6, 6 ', 6 ⁇ directed at an acute angle against the axis of the sleeve 2.
