Definitions

  • the invention relates to a method and devices for automatic thread application on a ring spinning machine, wherein the end of a broken thread is detached from the cone of the respective cop and sucked into a suction cup, after which the threading process begins in the presence of the thread in a suction line downstream of the suction cup.
  • a sensor is arranged in the above-mentioned suction line, which senses the presence of the thread in this suction line and on the one hand ends the activity of the blow-off nozzle and on the other hand initiates further steps of the attachment process.
  • This sensor can be designed as a mechanical feeler lever or as a light barrier.
  • the suction draft in the suction bell must be large enough to safely grasp and suck in the thread detached from the blow nozzle.
  • the induced draft must not be so large that it is the one in the intake pipe and thereby the we Kung the suction train exposed thread damage, for example, open or shorten, so that it no longer has the length required for a successful piecing operation. It has now proven to be difficult to produce a suction draft suitable for all occasions within the intake line.
  • the present invention has for its object to provide a construction in which damage to the thread within the suction line, especially at the beginning of the piecing process, is properly avoided.
  • This object is achieved in that after the thread enters the suction line, the suction pull acting on the thread is reduced. This results in the advantage of a damage-free holding of the thread within the suction line, in particular at the beginning of the piecing process.
  • the suction draft can be reduced in a further embodiment of the invention in that, for example, the speed of the motor driving the fan for the suction draft is reduced.
  • the construction can be designed in such a way that the suction line is provided with a bypass, which is opened when the sensor feels the thread in the suction line.
  • a number of spindles 4 are arranged above a spindle bank 1 of a ring spinning machine.
  • Each of these spindles 4 carries a cop 3, which is surrounded by an unspecified spinning ring fastened in a ring bench 2.
  • a blow-off nozzle 5 can be inserted below the ring bench 2 in order to initiate the automatic thread application in the event of thread breakage.
  • a suction cup 6, which is connected to an intake line 7.
  • This suction line 7 is connected to a suction fan 8, which is driven by a motor 9.
  • a sensor 10 is located within the suction line 7 and is designed, for example, as a mechanical feeler lever or as a light barrier. This sensor has the task of sensing the presence of the thread 18 in the suction line 7 and of actuating a control unit 11 via a line 17. This control unit 11 initiates the further method steps of the piecing process for the broken thread via a line 12.
  • the senor 10 also serves to reduce the suction within the suction line 7 when the thread in question is felt in the suction line 7.
  • One possibility here is that the speed of the motor 9 driving the fan 8 is correspondingly reduced via the control unit 11 if necessary. This results in a reduction in the suction draft within the intake line 7.
  • bypass 13 is provided, which is connected to the suction line 7. At the end, this bypass 13 is connected to an openable and closable flap 14 which can be actuated by an actuator 15. This actuator 15 is connected to the control unit 11 via a line 16.
  • Figure 2 shows another embodiment of the invention.
  • the device for reducing the suction is a control element 20, which is connected via a line 21 to the motor 9 driving the fan 8.
  • a reduction in the speed of the motor 9 driving the fan 8 can be achieved via this control element 20, which in turn provides the possibility of holding the thread 18 within the suction line without damage, particularly at the beginning of the piecing process.
