Definitions

  • the invention relates to a method for operating a workstation of a winding machine with a thread connecting device, in particular a splicing device for pneumatically connecting thread ends, and an intake air-loaded gripper tube which is pivotally mounted and formed for functionally correct positioning of its associated thread in the thread connecting device, said end a gripper tube flap is arranged for closing the thread-side opening of the gripper tube, and wherein the gripper tube flap has a control cam, via its engagement in a stationary shift gate, the open position of the gripper tube flap is controllable.
  • Such winder transfer a thread from a delivery reel on a package.
  • spin creels produced on a ring spinning machine come into question as a delivery reel.
  • the winder makes it cross-cheeks ago, which are better suited for further processing of the wound thread.
  • Such fully automatic, cross-wound producing spooling machines are also referred to as cross-spooling machines.
  • a thread automatic connection and, if necessary, a cop change mechanism are activated. That is, first, a suction nozzle is placed on the surface of the slowly rotating bobbin against the winding direction. After detecting the upper thread end, the suction nozzle pivots to its original position, in the suction nozzle opening is positioned below the splicer back, thereby inserting the upper thread in the splicer.
  • a gripper tube Almost simultaneously with the suction nozzle pivots a gripper tube from its zero position, which it occupies during normal winding operation, first in a lower position, then pivots in an upper working position and brings a hitherto held in a thread tensioner or in a clamping device, from the drain spool withdrawn bobbin thread with.
  • the gripper tube has at its end a gripper tube flap, which is opened when pivoting in the lower position by means of a shift gate. The negative pressure sucks the thread into the gripper tube.
  • the gripper tube flap is closed again and clamps the thread, so that it can be safely transferred to the splicer.
  • the DE 195 10 171 A1 discloses a generic winding machine.
  • the gripper tube is parked in a zero position in front of the normal threadline. In this position, the gripper tube has such a large distance from the running thread, that after a cleaner cut or a thread break the falling thread should not wrap around the gripper tube or the gripper tube flap, but falls past the gripper tube.
  • the thread after a break or cut often does not remain in its regular course, but can move uncontrollably due to the thread tension, which is suddenly relieved. The distance from the regular yarn path therefore does not provide sufficient protection against wraps of the gripper tube or the gripper tube flap.
  • the subsequent processes are adversely affected by these wraps. It can then no secure detection of the lower thread and thus no secure splice connection are guaranteed. In extreme cases, the wrap leads to a shutdown of the winding unit. Then an operator intervention is required and the thread must be removed manually.
  • the invention is therefore based on the object to remedy the aforementioned disadvantages or at least significantly reduce the likelihood of Fadenumschlingung the gripper tube or the hook tube flap.
  • the gripper tube is positioned during normal winding operation below a Fadenleitbleches arranged in the yarn path that the thread-side end of the gripper tube is completely covered by the gripper tube flap of the Fadenleitblech. In this way, the gripper tube is shielded by the yarn guide. A falling thread remains more likely to lie on the baffle than to wrap around the hook tube and the hook tube flap.
  • Fadenleitbleche are already available for threading and holding the thread in a given yarn path on winding machines.
  • the Fadenleitbleche are positioned above a clamping device. For the implementation of the method according to the invention therefore usually no mechanical changes are required.
  • the gripper tube is positioned during the normal winding operation so that the control cam touches the shift gate. In this way, a position of the gripper tube is realized close to the thread and thus positioned the opening of the gripper tube below the Fadenleitbleches.
  • the gripper tube flap can be opened very quickly.
  • the gripper tube during normal winding operation is positioned with respect to the shift gate, that the gripper tube flap is at least partially open. This positioning brings despite the compressed air loss described above, considerable advantages. Due to the continuous suction air, a falling thread can be caught directly. Furthermore, the gripper tube thus exerts a de-dusting function, so that in wind-up machines customary separate dedusting devices can optionally be omitted.
  • the gripper tube during normal winding operation is positioned so that the distance between the center of the thread-side opening cross section of the gripper tube and the yarn path is less than 40 mm.
  • this distance can be achieved on the one hand, that in many common winding machines, the thread-side end of the gripper tube is arranged under an already existing thread guide plate.
  • On the other hand is achieved by positioning with a distance of less than 40mm between the yarn path and the center of the opening cross section that the suction port of the gripper tube already arranged before the occurrence of a thread break or cleaner cut close to the thread and not only have to perform a long pivoting when the Threadline is interrupted. This shortens the time for the pivoting down of the gripper tube and the opening of the gripper tube flap in a thread break or cleaner cut.
  • a quick suction of the thread through the gripper tube also reduces the likelihood of looping.
  • the inventive position of the gripper tube during the normal winding process can also serve as a zero position and are always taken when the gripper tube receives no thread or transferred to the splicer. But it is also possible that the gripper tube a zero position in a larger Distance from the regular thread run can take and is pivoted closer to the thread only at the beginning of the winding operation.
  • a workstation of a winder with a thread connecting device and a suction gripper tube which is pivotally mounted and formed for functionally correct positioning of its associated thread in the thread connecting device, and end has a gripper tube flap for closing the thread-side opening of the gripper tube, the gripper tube flap a control cam, by the engagement in a stationary shift gate, the open position of the hook tube flap is controllable.
  • the gripper tube is automatically positioned by means of a control device.
  • a yarn guide is arranged in the yarn path.
  • the control device is adapted to automatically position the gripper tube during the normal winding operation such that the thread-side end of the gripper tube with the gripper tube flap is completely covered by the thread guide plate.
  • Fig. 1 shows in side view a job 10 of a cheese winder 1.
  • Such cheese machines have a variety of such juxtaposed jobs 10 on which feed bobbins 12, preferably spinning cops, are rewound to large-volume cheeses 14.
  • the spinning cops 12 arrive via a transport device 16 to the individual workstations 10, which, as known per se, includes a plurality of unspecified transport routes on which, plugged on transport plates 20, spin cops 12 and empty tubes 18 are conveyed.
  • a thread 22 is withdrawn from a spinning cop 12 arranged in a winding position 61, which initially passes on its way to the cheese 14 a lower thread sensor 28, which is connected via a signal line 30 to a workstation computer 32.
  • this lower thread sensor 28 for example, after a yarn break or a controlled thread cut, before initiating the Oberfadensuche determined whether at all a bobbin thread is present.
  • a device 36 which allows the clamping and clamping of the thread 22, is arranged above the lower thread sensor 28, a device 36, which allows the clamping and clamping of the thread 22, is arranged above the lower thread sensor 28, a device 36, which allows the clamping and clamping of the thread 22, is arranged.
  • the tensioning / clamping device 36 is also connected via a control line 38 to the workstation computer 32.
  • a yarn guide plate 63 is arranged above the tensioning / clamping device 36.
  • a thread cleaner 44 is arranged to detect yarn defects.
  • the quality of the running thread is constantly monitored, wherein the signals of the thread cleaner 44 are supplied to the Hästellenrechner32 for evaluation via a signal line 48.
  • the thread cleaner 44 may also have its own evaluation unit for quality control.
  • a yarn tension sensor 54 and a paraffining device 46 are still arranged.
  • the yarn tensile force sensor 54 is also connected via a signal line 56 to the workstation computer 32.
  • On the waxing device 46 follows in the direction of yarn finally a yarn guide 58, through which the thread 22 runs, for example, on a so-called yarn guide drum 60, which ensures a crosswise laying of the thread 22 according to the winding type "wild winding".
  • the cross-wound bobbin 14 is rotatably supported by a sleeve, not shown in a pivotally mounted creel 6 and lies with its outer periphery on the motor driven individually driven yarn guide drum 60, which carries the cross-wound bobbin 14 via frictional engagement.
  • a yarn splicing device 40 is also arranged, which is also connected via a signal line 42 to the workstation computer 32.
  • the suction nozzle 7 serves to receive an accumulated on the cheese 14 upper thread.
  • the gripper tube 8 serves to grasp the lower thread originating from the spinning cop 12 which is clamped in the tensioning / clamping device 36 in the case of a controlled thread cleaner cut or in the event of a yarn break above the tensioning / clamping device 36.
  • the gripper tube is pivotally mounted and has a motor drive, which is controlled by the workstation computer 32 via the control line 62.
  • FIG. 2 shows a section of the side view of the job.
  • the FIGS. 3 and 4 show for the same arrangement respectively a front view and a top view.
  • the gripper tube 8 has at its end a gripper tube flap 64 with a control cam 66.
  • Fig. 2 is the hidden by the hook tube flap 64 thread-side opening 67 indicated by a dashed line.
