Definitions

  • the invention relates to a device for automatic thread application on a ring spinning machine, in which an auxiliary thread drawn from a supply spool is applied to a cop or a sleeve by means of an ejector, the ejector being movable in the direction of the cop or the sleeve for thread application .
  • Another prior art is based on a method for automatically eliminating thread breaks on spinning machines, which is used when there is no thread on the sleeve or the thread end is not found on the cop (DE-OS 23 51 312). .
  • an auxiliary thread is first thrown onto the bobbin winding and then the thread end of this auxiliary thread is threaded through the wandering thread guide and runner and attached to the broken thread.
  • This method contains a number of process steps, and there is also the risk that the auxiliary thread is either not carried along by the bobbin winding or the thread end of the auxiliary thread is not found.
  • the object of the present invention is to design a construction of the type mentioned in such a way that an increased success rate when starting an auxiliary thread on a bobbin or a sleeve is ensured - if the torn end of the bobbin located on the bobbin is not detected can or if it is to be spun onto an empty tube.
  • the ejector is connected to a U-shaped thread guide screen which surrounds the cop or the sleeve in the advanced position for forming the loop of the auxiliary thread around the cop or the sleeve.
  • the device 1 shown in FIG. 1 for automatic thread application on a ring spinning machine 6 has a supply spool 2, on which an auxiliary thread 3 is wound. Furthermore, an ejector 4 which can be moved back and forth in the direction of the arrow according to FIG. 2 and a drive unit 19 is provided, for example a toothed rack / gearwheel which is driven by a motor 20 (FIG. 1). The ejector 4 is connected to a blast air source 17 which can be driven by a motor 21.
  • a conveyor device for the auxiliary thread 3 (not shown in more detail) and a tensioning device 14 which can be acted upon by an actuating member 15.
  • the conveyor means that the sufficient amount of auxiliary thread 3 with the appropriate tension is always supplied to the ejector 4.
  • a drive device 12 with a friction wheel 13 can be located below the ejector 4, as a result of which the sleeve or the cop 5 can be set in rotation.
  • the motors 20 and 21, the actuator 15 and the drive motor, not shown, of the friction wheel 13 are controlled by a control device 16.
  • the ejector 4 is equipped with a thread guide 7 for looping the auxiliary thread around a cop 5 or a sleeve, the sleeve 5 being arranged on a spindle 10 which is supported on a spindle bench 11.
  • the cop 5 or the sleeve is surrounded by a ring bench 8 of the ring spinning machine 6.
  • the cop 5 is surrounded by about 3/4 of the U-shaped thread guide 7 for forming the auxiliary thread around the cop 5.
  • the clear width of the thread guide 7 is advantageously about a quarter larger than the largest diameter of the cop 5.
  • the height H of the thread guide 7 corresponds to approximately three times the diameter of the mouth 9 of the ejector, the mouth 9 of the ejector 4 in half 1 and is oriented so that the blown air jet of the ejector runs past the axis A of cop 5 or sleeve.
  • the inner surfaces of the thread guide are at right angles to one another, in an embodiment which is not shown in more detail there is the possibility that the inner surface of the thread guide 7 is curved parallel to the axis A of cop 5 or sleeve.
  • This special design makes it easier to start an auxiliary thread on a sleeve 5 or a cop and ensures in a simple manner that the auxiliary thread is carried along by the cop or the sleeve.
  • the device according to the invention works as follows: If a thread attachment device has detected a thread break and has positioned itself in front of the relevant spinning position of the ring spinning machine 6, the motor 20 is switched on via the control device 16 and the ejector 4 is thus extended in the direction of the spindle 10 and in the optimal position Brought up position according to Fig. 2. At the same time, the motor 21 and thus the blown air source 17 are switched on via the control device 16 and the pump device is shown in FIG Auxiliary thread 3 unwound from the supply spool 2 by the measure of the delivery path of the ejector.
  • the spindle 10 is rotated by the friction wheel 13 of the drive device 12 and the conveyor device is switched to thread transport.
  • the thread transport speed of the conveyor is lower than the peripheral speed of the sleeve 5 or the cop, so that the auxiliary thread is kept tight.
  • This tightening of the auxiliary thread can also be done with the help of a tensioning device 14 which can be acted upon by an actuator 15.
  • the emerging from the mouth 9 of the ejector 4 auxiliary thread 3 is due to the air vortex forming within the thread guide to the sleeve 5 and, if the adjusting force between the sleeve and auxiliary thread or between the cop and auxiliary thread is large enough due to the wrap angle, from the surrounding sleeve.
  • the thread transport and the blown air are switched off via the control unit 16.
  • the ejector 4 is then retracted and the auxiliary thread 3 is separated from its connection to the supply spool 2 for further processing by means of a cutting device (not shown).
  • the functionally reliable application of the auxiliary thread 3 to the sleeve or the cop 5 is thus ended.
