Definitions

  • the present invention relates to a method for operating a partially or fully automatic spinning machine for producing cross-wound bobbins, in particular an open-end rotor spinning machine, with a plurality of similar, at least partially self-sufficient work stations arranged next to one another, each of the work stations having a spinning device for producing a thread and a winding device having a bobbin holder for winding the thread onto a cross-wound bobbin.
  • a spinning device for producing a thread
  • a winding device having a bobbin holder for winding the thread onto a cross-wound bobbin.
  • Partially or fully automatic spinning machines are known in various designs from the state of the art.
  • the workstations of these spinning machines each have a spinning device, for example an open-end spinning rotor, for producing a thread, a winding device for winding the produced thread onto a cross-wound bobbin and a large number of other elements for producing the thread and for handling the produced thread and the fiber material provided.
  • the essential components for producing the thread are the so-called spinning means, which in a rotor spinning machine include the spinning rotor, the thread take-off nozzle and the opening roller.
  • EN 10 2004 044 551 A1 It is proposed that the advisory work that is required be divided into manual and machine-based work steps. In this way, the operating personnel can carry out the manual work steps at work stations that have already been shut down, while an automatic maintenance device carries out the work steps that are to be carried out mechanically. In the case of a centrally driven spinning machine, where the batch change is carried out simultaneously at a large number of work stations, this can result in considerable time savings.
  • the EP 2 955 143 A1 describes a semi-automatic spinning machine in which display means are arranged at the individual work stations to show the yarn batch produced at the work station.
  • the display means are preferably designed as LED lights.
  • the object of the present invention is to propose a method for operating a spinning machine and a spinning machine which has a enables batch changes to be made as quickly as possible, even at individual workstations.
  • each of the work stations has a spinning device for producing a thread and a winding device having a bobbin holder for winding the thread onto a cross-wound bobbin.
  • the current batch is displayed at the workstations, especially by means of a color display.
  • the operating personnel can then quickly see which workstations are producing the same batch of yarn. This also helps to ensure that the Operating personnel are supported in determining a sensible sequence for carrying out manual maintenance. In addition, this makes it easier for operating personnel to check the condition and equipment of the respective work stations, for example whether the correct fiber material or the correct empty tubes are available for the yarn batch in question.
  • the need to carry out at least one manual maintenance activity at the work station which has reached the end of the batch can be indicated in various ways.
  • the need to carry out at least one manual maintenance activity is indicated by an occupancy status of the bobbin holder of the relevant work station.
  • the occupancy statuses of the bobbin holder can be, for example, "empty", "occupied” or "misoccupied”. If there is a discrepancy between the occupancy status of the bobbin holder and the display of the current batch at the work station, this signals to the operating personnel that at least one manual maintenance activity needs to be carried out. In this case, the display of the manual maintenance requirement is therefore carried out by components of the respective work stations themselves.
  • a storage position for empty tubes is provided at the work station, it is alternatively or additionally possible for the need to carry out at least one manual maintenance activity to be indicated by an occupancy status of the storage position for empty tubes.
  • the occupancy statuses "empty”, "occupied” or “misoccupied” are conceivable. If, for example, there is a discrepancy between the occupancy status of the storage position where an empty tube from the new batch is already located and the display of the still current, old batch at the work station, this in turn signals to the operating personnel a need to carry out at least one manual maintenance activity.
  • a wound cross-wound bobbin from a current batch is automatically removed and the need to carry out at least one manual maintenance activity is indicated by an empty bobbin holder.
  • the operating personnel can see from the empty bobbin holder that changeover work for a batch change must be carried out at this work station, because otherwise a new empty tube from the current batch would have been automatically inserted.
  • an empty tube from a new batch is provided in the supply position at the work station that has reached the end of the batch and the need to carry out at least one manual maintenance activity is indicated by the empty tube provided. Since the spool holder is still in the "empty" occupancy status, the operating personnel can see that manual maintenance activities must be carried out at this work station because otherwise the new empty tube would already have been inserted automatically. It is also possible that an empty tube from the new batch was provided in the supply position, but the current, old batch is displayed at the work station. From this discrepancy, the operating personnel can also see that there is a need to carry out at least one manual maintenance activity.
  • a wound cross-wound bobbin from a current batch is automatically removed and an empty tube from a new batch is automatically inserted.
  • the need to carry out at least one manual maintenance activity is indicated by an incorrectly occupied bobbin holder, since the empty tube of the new batch that has already been inserted does not match the display of the current batch at the work station.
  • the need to carry out at least one manual maintenance activity to be indicated by a combination of the three different indicators, namely the occupancy status of the spool holder, the occupancy status of the supply position and the display of the batch at the work station.
  • the three different indicators namely the occupancy status of the spool holder, the occupancy status of the supply position and the display of the batch at the work station.
  • the need to carry out at least one manual maintenance activity is indicated by an optical display element in the form of a graphic display assigned to the work station.
  • the operating personnel therefore do not have to draw conclusions from the prevailing constellation at the work station, as in the first two embodiments mentioned, but receive a direct and clear indication of the need to carry out at least one manual maintenance activity.
  • the need to carry out at least one manual maintenance activity is only indicated by a colored light or a specific flashing light, which of course must be different from the displays of other states at the work station.
  • the operating personnel must therefore know the exact meaning of the various colors and/or flashing signals in order to be able to assign them to different states on the spinning machine.
  • the optical display element is a graphic display, the operator is clearly and unambiguously informed in the form of text or graphic symbols that there is a need to carry out at least one manual maintenance activity.
  • the input device is a button on the display. In this case, the optical display element and the input device are combined in a touchscreen.
  • a further manual maintenance activity to be carried out is displayed on the display element.
  • the operator must therefore confirm that the first manual maintenance activity has been carried out and then receives precise information about which further specific maintenance activity is to be carried out. Of course, this can also be repeated several times so that the operator is guided step by step to carry out the necessary manual maintenance activities.
  • the confirmation of the execution of the respective maintenance activity is made using a button on the graphic display.
  • the operator can be instructed to replace the spinning rotor as the first maintenance task to be carried out, and to replace the fiber material as the second maintenance task.
  • Another maintenance task to be carried out can be to provide suitable empty tubes and, if necessary, replace the take-off nozzle.
  • a spinning agent exchange and/or a fiber material exchange is displayed as the manual maintenance activity to be carried out.
  • the operating personnel can immediately see from the "spinning agent exchange” or “fiber material exchange” display that several manual maintenance tasks have to be carried out and these particularly complex work areas are then given priority.
  • first and/or subsequent manual maintenance activities are displayed in the form of a text display and/or in the form of a graphic symbol.
  • the new batch is displayed at the relevant work station in addition to the current batch, in particular by means of a color display. This allows the operator to recognize before the end of the batch at the relevant work station that complex changeover work is pending and to have all the necessary new spinning agents, fiber materials, etc. ready. The time required for the batch change at the work station can thus be reduced even further.
  • the new batch is started at the work station, preferably started independently by the work station.
  • Manual confirmation of the execution of the required maintenance activities by the operator can ensure that all required steps have been carried out correctly. This avoids false detections, which can occur when control software queries them automatically.
  • a spinning machine for producing cross-wound bobbins in particular an open-end rotor spinning machine, with a plurality of similar work stations arranged next to one another is claimed.
  • Each of the work stations has a spinning device for producing a thread and a winding device having a bobbin holder for winding the thread onto a cross-wound bobbin.
  • the spinning machine also has a control device and a display element for carrying out the method described above.
  • FIG 1 shows a schematic front view of a spinning machine 1 for producing cross-wound bobbins in an overview.
  • the spinning machine 1 is designed as an automatic or at least partially automatic spinning machine 1 and has a large number of similar work stations 2 arranged next to one another, which are arranged between two end frames not specified here.
  • Each of the work stations 2 has a feed device for a fiber material 7, which in the case of an open-end rotor spinning machine is designed as an opening roller 8 (see Figure 1 ).
  • each of the work stations 2 has a spinning device 3 for producing a thread 6, a take-off device 9 for drawing off the produced thread 6 and a winding device 4 for winding the produced thread 6 onto a cross-wound bobbin 10.
  • the work stations 2 are designed as at least partially self-sufficient work stations. This means that the individual work stations 2 have a large number of individual drives for driving their thread-producing organs, so that the individual work stations can also be operated independently of the other work stations 2 of the spinning machine 1. Furthermore, the work stations 2 can independently resolve at least some of the faults that occur during operation without the need for an operating robot or the intervention of an operator. Other components, not shown here, such as handling organs and maintenance organs, are therefore arranged at the work stations 2. Furthermore, a display element 12 is provided at each of the work stations 2, which can, for example, display various operating states of the work stations 2 or the respective yarn batch produced. As an alternative to the illustration shown, it is also conceivable that two work stations 2 are assigned a display element 12 together.
  • FIG. 2 shows a work station 2 of such a spinning machine 1 in a schematic side view.
  • the spinning machine 1 is designed as an open-end rotor spinning machine and therefore has an opening roller 8 as a feed device and a spinning rotor 13 as a spinning element of the spinning device 3.
  • the thread 6 produced in the spinning rotor 13 is drawn off via a take-off nozzle 14 and fed to the winding device 4.
  • the winding device 4 has a bobbin holder 5 in which an empty tube 11 (see Fig.9 and 10 ) which can then be wound into a cross-wound bobbin 10.
  • a winding roller 19 is provided to drive the winding device 4.
  • the individual drives of the at least partially self-sufficient work stations 2 as well as other handling and maintenance elements of the work stations 2 are in Figure 2 also not shown.
  • the manual maintenance requirement is indicated by an optical display element 12, as described below with reference to Figures 3 to 8
  • FIG 3 shows a view of an optical display element 12, which is designed as a graphic display 15.
  • the display 15 shows a first display that indicates a regular operating state of the workstation 2. In this regular operating state, the current batch, here designated "A", is shown by a color display 20 (shown here in light dots). Furthermore, the regular operating state itself is shown by an easily understandable graphic symbol 16.
  • the display element 12 is assigned an input device 17, by means of which the Operators can make inputs and communicate with a control unit of workstation 2 (not shown here) and/or a central control unit (also not shown). In the present case, the display element 12 or the display 15 and the input device 17 are combined in one structural unit, so that the input device 17 is formed by various buttons 18 of the display 15. In the display shown here, the display 15 has, for example, a button 18 for retrieving information. By pressing this button, the operator can access the menu of the control unit of workstation 2 and make various settings there.
  • Figure 4 shows a view of the display element 12 or the display 15, which indicates a need to carry out at least one manual maintenance activity when the end of the batch of the relevant work station 2 is reached.
  • the current batch is still shown by the color display 20.
  • the need to carry out at least one manual maintenance activity is shown here by another, easily understandable graphic symbol 16. The operating personnel can use this symbol to very quickly see that manual activities are to be carried out at this work station 2 and can therefore work on these work stations 2 preferentially or plan the maintenance of the relevant work stations better.
  • the display of the need to carry out at least one manual maintenance activity is again designed as a button 18 in the present case, which can be recognized both by the frame surrounding the button 18 and by the prompt to actuate it by means of the check mark. If the operator now presses this button 18, he receives more detailed information on which specific maintenance activities are to be carried out in a subsequent display.
  • Figure 5 now shows another display on the display 15, which the operator can see after pressing the button 18 of the previous display ( Figure 4 ) or, in the general case after actuating the input device 17, displays the manual maintenance activity to be carried out.
  • the task "Check Spinning Components" is displayed in the form of a display text. This and any subsequent displays inform the operator that he must check the spinning components and replace them if necessary.
  • the advantage here is that the same displays can be used for both faults in regular spinning operations that lead to a standstill at work station 2 and when maintenance is required due to an upcoming batch change.
  • the operator only needs to be informed that at least one manual maintenance activity needs to be carried out and is then guided through the menu and given step-by-step instructions.
  • the operator therefore does not need to differentiate between faults in regular operations and batch changes and does not need to think about which manual maintenance activities he needs to carry out in which case, but simply needs to follow the instructions that can be called up one after the other, as will be explained below.
  • the displays of the manual maintenance activities to be carried out also contain a button 18, by means of which the operator must confirm the execution of the maintenance activity after it has been completed. After the operator has confirmed the execution of the maintenance activity , another required manual maintenance activity may be displayed, which the operator must also confirm, whereupon another required manual maintenance activity may be displayed.
  • the operating personnel can thus see at first glance that the need to carry out at least one manual maintenance activity involves a batch change with a spinning agent change and can give priority to these work stations 2. This is particularly advantageous if specially trained personnel are required for such a spinning agent change. The personnel can thus immediately see whether simple manual maintenance activities are to be carried out or a spinning agent change for which specially trained personnel is required.
  • FIGS 9 to 11 finally show an alternative embodiment in which the need to carry out at least one manual maintenance activity is indicated by the occupancy state of the spool holder 5 or the occupancy state of a supply position 22 for empty tubes 11.
  • FIG. 9 a situation in which workstation 2 has reached the end of the batch and has already been shut down.
  • empty tubes 11 of the new batch are already provided at spinning machine 1.
  • the batch change has already been initiated by the control unit of workstation 2 and/or spinning machine 1 by inserting an empty tube 11 of the new batch into bobbin holder 5, as can be seen from the dark dotted color of the empty tube.
  • display element 12 still shows the color display 20 of the just finished, still current batch.
  • the inserted empty tube 11 does not match the displayed batch, so that bobbin holder 5 has the "incorrectly loaded” status. Operating personnel can therefore recognize from the idle workstation 2 and the incorrect occupancy of the bobbin holder that a batch change is pending and manual activities must be carried out.
  • Figure 11 shows a work station 2, which additionally has a supply position for empty tubes 11, whereby the need to carry out at least one manual maintenance activity is indicated by the empty tube 11 provided.
  • the work station 2 has again reached the end of the batch and has already been shut down.
  • empty tubes 11 of the new batch are already provided on the spinning machine 1.
  • the batch change has already been initiated by the control unit of the work station 2 and/or the spinning machine 1 by providing an empty tube 11 of the new batch (dark dotted color) in the supply position 22, but has not yet been inserted into the bobbin holder 5.
  • the bobbin holder 5 therefore has the "empty" occupancy status. The operating personnel can therefore recognize from the empty tube provided and the "empty" occupancy status of the bobbin holder that a batch change is pending and that manual activities must be carried out.
  • the color display 20 of the currently completed batch is also shown by the display element 12.
