Definitions

  • the invention relates to a method for operating workstations of an open-end rotor spinning machine according to the preamble of claim 1 and to a workstation according to claim 5.
  • Open-end rotor spinning machines which have a variety of jobs and where the jobs are powered by mobile, self-acting service units have long been known and described in detail in numerous patent applications.
  • open-end rotor spinning machines are known whose jobs are designed as largely self-sufficient jobs.
  • Such workstations have, inter alia, in each case an open-end spinning device for producing a thread and a winding device for producing a cross-wound bobbin.
  • the winding device preferably has a defined pivotally mounted creel, acted upon by a reversible single drive drive drum and a motor driven Einzelchaser Fadenchangier affection.
  • a pivotally mounted, first suction nozzle which is adjustable by means of a single drive between a thread receiving position in the region of a held in the winding device cheese and a yarn transfer position in the field of open-end spinning device.
  • a fiber sliver initially placed in a sliver can, for example, is spun onto a yarn at such work stations, which sliver is then wound up into a cross-wound bobbin.
  • the jobs each have a, in professional circles also referred to as a third hand, short suction pipe, which is connected to a separate, machine-long vacuum channel and closed during the "normal" spinning operation.
  • This suction tube is used in particular in connection with cheeses / empty tube changes, which are performed manually in such semiautomatic OffenendRotorpinnmaschinen and in which the spinning process is not interrupted at the affected job.
  • the jobs of this known OffenendRotorpinnmaschine are each equipped with two stationary suction nozzles.
  • the first suction nozzle is arranged in the direction of yarn travel between the thread withdrawal device of the job and a Fadenchangier worn and has the function in the event of a yarn break to receive the fürprodu approachen by an open-end spinning device of the affected job thread.
  • the second suction nozzle is positioned in the thread running direction just behind the bobbin drive roller arranged in the region of the winding device of the work station and has a thread cutting device which can be actuated by a switching device of the bobbin frame.
  • the operator After the operator has manually inserted a new empty tube in the creel, the operator lowers the creel and thus the empty tube in the direction of the bobbin drive roller, wherein when placing the empty tube on the bobbin drive roller an adhesive zone of the empty tube detects the incoming into the suction nozzle thread.
  • the thread cutting device integrated in the second suction nozzle is actuated by a switching device on the creel, which separates the yarn between the finished, to be replaced cross-wound bobbin and the newly inserted empty tube.
  • the thread is hooked by the open-end spinning device further running thread by the operator by hand in the traversing yarn guide and thus started a new winding process.
  • the present invention seeks to develop a method which makes it possible that the jobs of a OffenendRotorspinnmaschine if necessary, can also automatically perform cross coil / empty tube change. That is, the jobs should be designed so that in a cheese / Leerhülsenic neither the use of a cleaner and changer car necessary, nor a manual intervention by the operating personnel is required.
  • the winding process of the cross-wound bobbin is initially interrupted when a predetermined diameter of the cross-wound bobbin from the work and a cross-coil / empty tube change initiated. That is, the thread produced by the open-end spinning device is first temporarily disposed of by a second suction nozzle positioned as required by a drive device in the area of a winding device of the workstation and transfers the finished cross-wound bobbin to a spinning machine-specific transport device by appropriate control of a creel. Subsequently, the bobbin frame is equipped with a new empty tube from a work-empty envelope magazine and finally the bobbin frame pivoted back in a winding position.
  • the movably mounted second suction nozzle is then positioned so that the yarn entering the movably mounted second suction nozzle is transferred to the empty sleeve held in the coil frame and the winding process to the new empty sleeve is restarted.
  • the waiver of a spinning break and the associated piecing process has the advantage, among other things, that at the work site, at least at this time, no time-consuming cleaning operations are necessary, with the result that the process steps described in claim 2 to minimize the on the Jobs for a cheese / empty tube change require time consuming lead.

That is, such a training of jobs allows at any time to carry out a necessary cheese / empty tube change. In this way, the downtimes occurring at the workstations of open-end spinning machines in connection with cheese / empty tube changes can be minimized, which has a very positive effect in the calculation of the overall efficiency of such open-end spinning machine.
