  • this upper thread is picked up by means of a suction nozzle, cleaned and connected to a so-called lower thread in a thread splicing device.
  • a suction nozzle under vacuum is also pivoted into the area of the surface of the cheese. The suction nozzle pneumatically picks up the thread end and places it in the thread splicing device, where, as indicated above, it is connected to the lower thread.
  • the thread is traversed via a so-called finger thread guide, while the cheese is driven directly.

  • one of the two sleeve plates rotatably mounted in the coil frame is directly connected to a speed-adjustable drive.
  • the package lies on a freely rotatable support roller during winding operation, which is carried by the package via friction.
  • the bobbin frame is first raised, as is known, and the cross-wound bobbin is braked to a standstill by the bobbin drive which is subjected to a braking current.
  • the back-up roller is also braked by a special device.
  • DE 198 17 363 A1 describes a work station of a textile machine, the winding device of which has a winding drum and a coil frame, which can be raised by a so-called torque sensor.
  • a drive element preferably a stepper motor, is connected to the torque transmitter. If necessary, the torque transmitter can be acted upon in a defined manner by appropriate, gradual adjustment of the drive element and a torque can thus be applied to the coil frame via the torque transmitter. This means that the package can be lifted off the winding drum in a targeted manner by the defined introduction of this torque.

  • An advantageous embodiment of an inventive Device is the subject of claim 6.
  • the method according to the invention has the particular advantage that it is consequently avoided that after a thread break or a defined cleaner cut the upper thread running onto the surface of the package can be rolled into this surface.
  • the method according to the invention ensures in a simple manner that even with problematic yarns, the upper thread can always be handled pneumatically by the suction nozzle and is not ironed into the surface of the package, as has often been the case in the past, that it no longer passes through the suction nozzle is recordable.
  • the bobbin frame remains raised at least so far during the take-up of the upper thread that there is a minimal distance between the surface of the package and the associated support roller.
  • the bobbin frame remains in this position, which protects the surface of the cheese, until the winding process is started again.
  • the device for performing the method according to the invention in a preferred embodiment has a device in which the coil frame can be acted upon by a so-called torque sensor.
  • the torque transmitter connected to the swivel axis of the coil frame can be adjusted in a defined manner by means of a drive element and thus outputs a predeterminable torque on the coil frame.
  • the torque which can be introduced onto the coil frame by the torque transmitter is preferably slightly larger than an oppositely acting, calculable torque which results from the dead weight of the coil frame and the respective coil weight.

  • Such stepper motors can due to their constructive Can be adjusted in very small steps and therefore enables a sensitive adjustment of the to the Coil frame torque to be initiated. Also hires such stepper motor is a robust and inexpensive Large series component.
  • the lifting of the coil frame takes place via a pneumatic thrust piston gear.
  • a damping cylinder arranged in the housing of the winding unit is designed such that compressed air can be applied to it via an electromagnetic valve that can be controlled by the winding unit computer. The damping cylinder lifts the bobbin frame if necessary and holds it in this raised position until the winding process is started again.
  • FIG. 1 shows a first embodiment of a work station 1 of a textile machine producing cross-wound bobbins.
  • a work station 1 has, as is known, a winding station housing 2 on which a spool frame 5 and, freely rotatable, a support roller 3 are pivotally mounted.

  • a sleeve is held between the bobbin plates, onto which a thread can be wound to form a cheese 4.
  • a spool drive 20 is integrated into one of the spool frame arms 7, 8 of the spool frame 5, which acts on a connected sleeve plate of the spool frame 5 and thus drives the cross-wound bobbin 4 directly.
  • the cheese 4 in turn takes the back-up roll 3 by friction.
  • a torque transmitter engages on the pivot axis 6 of the coil frame 5.
  • the torque transmitter 30 has, inter alia, a connecting disk 9 which is connected in a rotationally fixed manner to the pivot axis 6.

  • the rotatably mounted gear 10 meshes with a pinion 14 of a reduction gear, the outer ring 15 of which is connected via a drive pinion 16 to a drive element 17, preferably a stepper motor. Since the drive pinion 16, the outer ring 15 and the pinion 14 are rotatably mounted on the winding unit housing 2, any rotary movement of the stepping motor 17 fixed on the winding unit housing 2, for example in a ratio of 1:25, can be transmitted to the gearwheel 10 via the reduction gear.
  • the stepper motor 17, which is designed, for example, for individual steps of approximately 1.8 degrees, is controlled via a control line 19 by a winding station computer 18 and is thus able to carry out a predetermined number of revolutions or a predetermined number of individual steps, which by means of the torque transmitter 30 Coil frame 5 give a torque M on .
