Definitions

  • the invention relates to a method for determining the required speed of a bobbin drive roller when driving a conical sleeve or cross-wound bobbin, which is held in the bobbin frame a job of a cheese-producing textile machine, the single-motor controlled bobbin drive roller of the job frictionally drives the conical sleeve and later cheese, and a Cheese-making textile machine for carrying out the method.
  • a method for controlling a traversing device driven by a single motor drive on a device for winding conical cheeses and a textile machine producing cross-cheeses are known, for example, from US Pat CH 698 687 A2 known.
  • a so-called conicity factor is determined in advance.
  • This Konizticians tone describes the ratio of the thread laying speeds at the end faces of the cheese and is specified to the winding station computer.
  • a modified Konizticianstex is fixed at the beginning of the coil travel, which approaches in the course of the coil travel to the beginning of the coil assembly set value.
  • the DE 29 11 340 A1 describes a method for cross-winding a thread and a device for driving a bobbin on which the thread is wound.
  • a drive shaft with a concentrically arranged drive bale whose diameter is dimensioned slightly larger is used as the actual diameter of the roller, so that it comes in the contact area, which is located in the middle coil area, to a reliable frictional engagement between the drive shaft and cross-wound bobbin.
  • a disadvantage of the method according to the prior art proves that the manufactured conical cheeses do not always meet the required high quality standard.
  • the Konizticians tone is based on a theoretical value and can only approximate the actual tube or bobbin diameter, while the bobbin drive roller with special roller surface for conical sleeves / coils not only requires a second bobbin drive roller for the production of cylindrical coils, but also a conversion of the machine Change the format of the coils to be produced.
  • the bobbin frame must be aligned very accurately to the bobbin drive roller, since even bobbin drive rollers with a special roller surface prevent limited entrainment on the sleeve or coil edge. Often an adjustment of the creel is necessary. Although due to the elasticity of the winding body, the behavior is equalized from a certain thickness of lining, and cheeses not running parallel to the bobbin drive roller are less detrimental. Nevertheless, this remains a quality problem and can negatively affect subsequent processes.
  • the driven diameter is the diameter at which the peripheral speed of the cheese coincides with the peripheral speed of the drive roller; he is subject, especially at the beginning of the cross-wound coil construction slip-related fluctuations.
  • a strong fluctuation in the position of the driven diameter in turn causes a change in the yarn speed or the yarn tension.
  • the actual drive point on the conical sleeve and later on the conical cheese may deviate from the geometric centerline. Is the contact area of the conical sleeve with the coil drive roller, with respect to the geometric center line, on the narrower side of the bobbin, so the winding tension increases; However, if this contact area lies on the wider side, the sleeve or cross-wound bobbin has a lower winding speed.
  • the object of the present invention is to propose a method or a device which reduces the fluctuations of the speed of cheeses, in particular at the beginning of the coil travel.
  • the detection of the speed pulses already takes place before an application process, so that the respective drive diameter of the sleeve or cross-wound bobbin takes place during the application process when selecting the adapted speed range of the bobbin drive roller.
  • this rotational speed can be controlled during the piecing process so that a pneumatic yarn store of the work station is emptied in the predetermined time. Due to the precise control of the pneumatic thread store, thread breaks due to excessive winding tension and loose thread layers due to insufficient winding tension can be avoided.
  • each job has a device that senses the pulses of rotating on the bobbin drive roller sleeve or cross-wound bobbin and forwards to a control device, from the timing of the pulses the drive diameter of the sleeve or cross-wound bobbin and from it as a result, the speed of the bobbin drive roller adapted to the drive diameter is calculated.
  • FIG. 1 shows a side view of a job 2 an open-end rotor spinning machine 1.
  • Such an open-end rotor spinning machine 1 has on its two longitudinal sides of each machine a plurality 2. Construction and mode of action of the workstations 2 are in each case identical, so that the explanation is made only on the basis of a workstation 2.
  • FIG. 1 and FIG. 2 show a job 2, which has an open-end spinning device 3 and a winding device 4 including a suction nozzle 25.
  • a sliver 6 presented in sliver cans 5 is spun into a yarn 7.
  • the thread 7 is then wound in the winding device 4 to a cross-wound bobbin 8.
  • the cross-wound bobbin 8 is held in a winding frame 9 during the spinning / winding process in the winding device 4 and is thereby driven via a bobbin drive roller 10 by means of frictional engagement.
  • the coil frame 9 is mounted pivotably about a pivot axis 11.
  • the thread 7 is withdrawn from the open-end spinning device 3 by a thread withdrawal device 12, which consists of a driven roller and a pressure roller resting on the roller, with a defined, uniform yarn delivery speed.
  • the withdrawal speed of the stripping device 12 thus determines the delivery speed of the thread 7 and thus the winding speed with which the thread 7 has to be wound onto the cross-wound bobbin 8.
  • a thread store 13 In the thread running direction of the thread withdrawal 12 a thread store 13, a waxing device 14 and a thread guide 15 are arranged downstream.
  • the yarn guide 15 alternates in a straight line in front of the outer circumference of the cheeses 8 and thus ensures, with simultaneous drive of the cheese 8 on the bobbin drive roller 10 that the yarn 7 is wound in intersecting layers on the cheese 8.
  • the open-end rotor spinning machine 1 is associated with an only indicated here, automatically operating control unit 22, which is guided with its chassis 23 on rails 24.
  • the rails 24 extend in the superstructure of the open-end rotor spinning machine 1, on which the operating unit 22 along the open-end rotor spinning machine 1 is movable.
  • the operating unit 22 comprises a plurality of handling devices, not shown in detail, for cleaning the spinning rotors or for changing the cheeses 8.
  • the operation of the jobs 2 is, for example by the DE 10 2005 036 485 A1 or the DE 101 39 075 A1 so that it need not be discussed further in the context of the present description.
  • FIG. 2 illustrates in perspective view a job 2 an open-end rotor spinning machine; the thread 7 leaves the open-end spinning device 3 by a so-called thread withdrawal tube 29, in the area also a pivotally mounted Anspinncousorgan 27 is arranged, which takes after a thread interruption by a suction nozzle 25 from the cheese 8 back retrieved thread 7 and the thread end to the thread connection prepared.
  • a thread monitor 30, a pneumatic thread storage device 13 and a waxing device 14 are arranged in the area of the thread running path.
  • the pneumatic thread storage device 13 is designed as a discontinuous working memory, that is, the thread storage device 13 is completely emptied after each thread connecting operation. During operation of the open-end spinning device 3, the thread storage device 13 is acted upon if necessary via a vacuum source, not shown, with suction air.
  • Such work stations 2 have a suction nozzle 25, which is adjustable by means of a stepping motor 17 between a thread receiving position lying in the region of the winding device 4 and a yarn transfer position lying in the region of the spinning device 3.
  • the individual stepper motors of the components of the workstation 2 are connected via various control lines to a control device, in the present exemplary embodiment to a workstation computer 19.
  • the individual motor drives of the components of the workstations 2 can be controlled independently of each other.
  • the inventive method will be described below with reference to the illustrated embodiments of the open-end rotor spinning machine.
  • the yarn winding speed of a cross-wound bobbin 8 results from the rotational speed and the diameter of the bobbin drive roller 10 and the driven diameter of the cheese 8.
  • the yarn winding speed of the winding device 4 must be matched with the yarn guide speed of the thread traversing device 15 to the yarn delivery speed of the spinning device 3 be.
  • the speed is by the inventive measures the bobbin drive roller 10 individual motor 28 adapted to the respective drive diameter, so that the supply of the yarn 7 takes place at a constant winding tension.
  • the thread store 13 is emptied in the predetermined time.
  • a piecing process In a piecing process, first the sliver feed, the drives of the thread take-off roll 12, the Fadenchangier immunity 15 and the bobbin drive roller 10 are stopped and the cheese to be produced 8 is lifted by means of the coil frame 9 of the bobbin drive roller 10. Subsequently, a piecing process is initiated, wherein the sliver feed, the drives of the thread take-off roll 12, the Fadenchangier immunity 15 and the bobbin drive roller 10 are put into operation synchronously to initiate the piecing process again.
  • the commissioning of the thread take-off roller 12, the Fadenchangier noisy 15 and the bobbin drive roller 10 is carried out taking into account temporally coordinated acceleration processes of the individual drives, which should take into account in particular the different moments of inertia and the traction of the operating components to be taken into account.
  • the invention provides that the angular momenta of the cheese 8 are sensed before a piecing or piecing process, as well as from the time sequence of the respective drive diameter is calculated to based on it already at the beginning of the bobbin travel, the speed of the bobbin drive roller 10 choose.
