Definitions

  • the present invention relates to a method for operating a workstation of a spinning machine, wherein a yarn is drawn off from a spinning unit at a take-off speed during normal operation, the yarn being monitored with the aid of a quality sensor with regard to at least one yarn parameter, the yarn being wound in with the aid of a winding device a winding speed is wound onto a tube and a bobbin is formed, the yarn being moved back and forth along a traversing width when being wound onto the tube, and a stop sequence being initiated upon detection of a yarn defect-related deviation from a target value of the at least one yarn parameter by the quality sensor .
  • the invention further relates to a workstation of a spinning machine.
  • the spinning machines can be designed, for example, as air-jet spinning machines or rotor spinning machines.
  • the aim here is to initiate a stop sequence in the event of a deviation from a target value of at least one yarn parameter.
  • a method for operating a spinning station of a spinning machine in which a stop sequence is initiated upon detection of a defined deviation of a monitored yarn parameter from at least one setpoint.
  • the spinning unit and the winding unit are stopped in such a way that the last yarn section produced does not completely run onto the tube located in the winding device.
  • the yarn section that has the detected deviation in the yarn parameter is wound onto the tube with an indeterminate length of subsequent yarn. This indefinite length of subsequent yarn must then be used be unwound and cut off again. This creates a large amount of yarn waste.
  • the object of the present invention is to eliminate the disadvantages known from the prior art.
  • the task is, in particular, to create a method for operating a workstation of a spinning machine and a workstation that makes it easier to locate the end of the yarn, improves the winding of the yarn onto the tube and/or reduces yarn waste.
  • the spinning machine is preferably an air or rotor spinning machine.
  • the spinning unit includes, for example, a vortex chamber or a rotor and produces the yarn from a supplied fiber material.
  • the yarn is then drawn off from the spinning unit by a take-off device.
  • the withdrawal speed is the speed of the yarn at which it is withdrawn from the spinning unit.
  • the workstation usually includes other elements necessary for yarn production, such as a drafting system for stretching and/or an opening roller for separating the fiber structure.
  • the yarn After leaving the outlet of the spinning unit, the yarn is monitored with the aid of a quality sensor with regard to at least one yarn parameter.
  • yarn parameters include thickness and hairiness or to understand other parameters that characterize the quality of the yarn or their fluctuations over time.
  • the yarn is then wound onto a tube at a winding speed using a winding device and a bobbin is thus formed, with the yarn being moved back and forth along a traversing width when being wound onto the tube.
  • the workstation has a traversing device for moving the yarn back and forth along the traversing width.
  • the traversing width is the distance between the two turning points of the traversing device.
  • the term sleeve refers to the body onto which the yarn is wound.
  • the term spool is understood to mean the combination of the sleeve mentioned and the yarn located on the sleeve.
  • the winding speed is the speed at which the yarn is wound onto the tube or onto the surface of the spool.
  • the winding speed is therefore the speed of the yarn shortly before it runs onto the tube or onto the bobbin.
  • the winding speed is primarily dependent on the speed of the sleeve or bobbin, the outer diameter of the bobbin, the traversing width and/or a traversing frequency with which the traversing device moves along the traversing width.
  • a stop sequence is a sequence that stops the normal operation of the workstation.
  • the stop sequence is the chronological sequence of different operations when normal operation is stopped.
  • Individual elements, such as the spinning unit, the winding device, the take-off device and/or the traversing device, can be stopped step by step or simultaneously.
  • the quality sensor can be arranged between the spinning unit and the take-off device. Additionally or alternatively, the quality sensor can be arranged between the take-off device and the winding device.
  • the method provides that the winding speed is reduced during the stop sequence, with a yarn loop forming due to the resulting speed difference between the winding speed and the take-off speed.
  • the take-off speed remains essentially constant and/or the reduction in the take-off speed is less than the reduction in the winding speed, so that the yarn loop is formed.
  • the position of the defect between the quality sensor and the winding device and/or on the bobbin can be localized more precisely due to the slowed down winding.
  • the yarn tension during the slow winding of the yarn onto the tube during the stop sequence remains approximately constant despite the difference in speed due to the yarn loop formed. In this way, fluctuations in the yarn tension that arise from reducing the winding speed and/or from moving the traversing device back and forth along the traversing width with the traversing frequency can be compensated for.
  • the traversing width is reduced during the reduction of the winding speed and/or subsequently.
  • the yarn runs onto the sleeve or onto the tube within this reduced traversing width surface of the coil. This can ensure that the defect then runs onto the spool within this traversing width. This makes finding this defect easier.
  • the lower yarn tension resulting from reducing the traversing width can be compensated for by increasing the size of the yarn loop. In this way, constant yarn tension can still be guaranteed while at the same time reducing the traversing width.
  • the yarn is separated in the area of the yarn loop, with a resulting yarn end on the bobbin side being guided towards the bobbin at the winding speed. If the yarn is separated in the area of the yarn loop after the winding speed is reduced, the end of the yarn is guided slowly towards the bobbin. Due to the reduced winding speed, the end of the yarn can be stopped before it emerges, especially at a pick-up position. This makes it easier to find and/or pick up during a subsequent piecing process. If the yarn is additionally or alternatively cut after reducing the traversing width in the area of the yarn loop, the position of the defect and/or the yarn end can be additionally limited in width when it is guided towards the bobbin.
  • the buffer store preferably works pneumatically and sucks in the yarn using negative pressure.
  • the buffer storage ensures that the yarn tension is maintained. If the yarn loop is separated in the buffer, the yarn end on the spool side can be led out of the buffer again against the direction of the suction when it moves towards the bobbin. The yarn end on the take-off side can be diverted or sucked away by means of the pneumatically operating buffer.
  • a yarn cutting device is advantageously arranged in the intermediate storage.
  • the yarn sucked into the buffer by means of negative pressure is then separated by the yarn separating device.
  • the yarn separating device By arranging the yarn separating device within the intermediate storage, the sharpest possible yarn end can be produced, in particular by maintaining the yarn tension. This sharp yarn end simplifies subsequent locating, picking up and/or spinning.
  • the arrangement of the yarn separating device within the intermediate storage has the advantage that the most compact workstation possible is created.
  • the traversing width is reduced to almost zero, whereby the yarn runs onto the bobbin in at least one parallel winding.
  • the reduction of the traversing width to approximately zero is to be understood as meaning that the yarn can wind onto the surface of the bobbin in approximately parallel windings.
  • the windings of the yarn are strung together with a small width, so that parallel windings are created.
  • the defect runs onto the surface of the coil in the area of the at least one parallel winding.
  • the end of the yarn on the spool side is preferably stopped before it runs onto the spool.
  • the at least one parallel winding runs onto the center of the coil.
  • the traversing width which is preferably reduced to approximately zero, is thus formed centrally to the coil.
  • the defect runs onto the surface of the coil in the middle of the area of at least one parallel winding.
  • the spool-side yarn end is preferably stopped before it runs onto the spool, with the pick-up position of the spool-side yarn end thus being arranged essentially centrally to the spool. Through the central pick-up position of the yarn end on the spool side makes it easier to find and/or pick up.
  • the take-off speed and/or the winding speed is reduced to a standstill.
  • the yarn monitor is preferably arranged between the take-off device and the winding device and/or between the intermediate store forming the thread loop and the winding device. In this way, the end of the yarn on the spool side can be detected before it runs onto the spool. Additionally or alternatively, the traversing device can be stopped. This allows the stop sequence to complete. The defect can then advantageously be removed and/or the piecing process can be started.
  • the winding device continues to operate after the yarn monitor has detected the passage of the yarn end on the spool side until the yarn section with the deviation caused by the yarn defect runs onto the surface of the spool and/or the yarn end on the spool side is arranged at a pick-up position. This ensures that the pick-up position remains constant at all times.
  • the invention further relates to a workstation of a spinning machine, with a withdrawal device for withdrawing a yarn from a spinning unit, with a quality sensor for monitoring the yarn with regard to at least one yarn parameter, with a winding device for winding the yarn onto a tube, and with a traversing device for back and forth moving the yarn along a traversing width during winding.
  • the workstation has a control unit which is designed to operate the workstation according to the previous description, whereby the features mentioned can be present individually or in any combination.
  • the workstation has a, preferably pneumatically operating, buffer for forming a yarn loop.
  • the buffer has a yarn cutting device for cutting the yarn in the area of the yarn loop.
  • Figure 1 shows a section of a schematic front view of a workstation 1 of a spinning machine during normal operation.
  • a yarn 3 is drawn off from a spinning unit 4 at a take-off speed by means of a take-off device 2.
  • the take-off device 2 is preferably designed in the form of a pair of take-off rollers.
  • the spinning unit 4 is a spinneret with a vortex chamber of an air-jet spinning machine, in which fibers of a fiber material are twisted into the yarn 3 using a vortex air flow.
  • the feeding of the fiber material, which in air-jet spinning machines is usually achieved by means of a drafting system, is not shown here.
  • the fiber material is usually dissolved into its individual fibers using a dissolving device.
  • the spinning unit 4 has a rapidly rotating rotor to form the yarn 3.
  • the yarn 3 After leaving the spinning unit 4, the yarn 3 is monitored with the aid of a quality sensor 5 with regard to at least one yarn parameter. With the help of a yarn monitor 15, the presence of the yarn 3 can then also be monitored. The yarn 3 is then wound onto a tube 7 at a winding speed using a winding device 6, whereby a bobbin 8 is created. For additional guidance of the yarn 3, a yarn guide element 9 can be arranged between the yarn monitor 15 and the winding device 6. To produce a cheese, the yarn 3 is moved back and forth along a traversing width CB when winding onto the sleeve 7 or onto the surface of the spool 8 using a traversing device 10.
  • the traversing width CB is selected such that the traversing device 10 can distribute the yarn 3 evenly over a winding width SB on the sleeve 7 or on the surface of the bobbin 8.
  • the traversing width CB during normal operation of the workstation 1 is essentially equal to the winding width SB.
  • the workplace 1 has a control unit 11.
  • the control unit 11 is designed in such a way that it can operate the components of the workstation 1 according to appropriately stored specifications, in particular according to the previous and/or subsequent description. Additionally or alternatively, the control unit 11 can be arranged centrally on the spinning machine and operate one or more work stations 1 of the spinning machine according to the specifications. The control unit 11 is in operative connection with the workstation 1.
  • a yarn loop S is formed by reducing the winding speed and the resulting speed difference between the winding speed and the take-off speed.
  • the winding speed depends primarily on the speed of the sleeve 7 or the spool 8, which is introduced by the winding device 6, and its diameter.
  • the take-off speed is primarily dependent on the rotation speed of the take-off roller pair of the take-off device 2.
  • the workstation 1 has a buffer 12 to form the yarn loop S.
  • the buffer 12 is preferably operated pneumatically.
  • the buffer 12 is arranged between the quality sensor 5 and the yarn monitor 15 or between the take-off device 2 and the yarn monitor 15. Due to the slower winding speed, the yarn error-related deviation F is then guided more slowly towards the bobbin 8.
  • the traversing width CB is reduced.
  • Figure 3 shows this point in time in the stop sequence, with the traversing width CB reduced to approximately zero.
  • the yarn loop S can be enlarged by reducing the traversing width CB.
  • the yarn 3 is separated in the area of the yarn loop S using a yarn cutting device 13.
  • a resulting yarn end 14 on the bobbin side is guided further towards the bobbin 8 at the winding speed together with the yarn error-related deviation F.
  • This point in time of the stop sequence is in Figure 4 shown.
  • the winding speed is reduced to a standstill.
  • the yarn end 14 on the spool side comes to a standstill before running onto the surface of the spool 8.
  • the position of the yarn end 14 on the spool side shown is called the pick-up position.
  • the pick-up position is arranged essentially centrally to the sleeve 7 or to the coil 8.
  • the yarn error-related deviation F is wound on the surface of the spool 8 in the area of the at least parallel winding PW.
  • the spinning unit 4 can stop the production of the yarn 3 and then the take-off speed can be reduced to a standstill.
  • the yarn 3 produced after the yarn 3 has been cut can be sucked out using the buffer 12. The stop sequence is then ended.
  • the yarn end 14 on the spool side can be prepared for piecing.
  • the spool-side yarn end 14 is picked up at the pick-up position with the help of the workstation's own means and/or with the help of a service robot, the at least one parallel winding PW is unwound from the spool 8, the yarn error-related deviation F is removed and the spinning unit 4 is returned.
  • work station 1 can resume normal operation.
