Definitions

  • the present invention relates to a method for operating a partially or fully automatic, cheese-making spinning machine, 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 bobbin holder having winding device for winding the thread onto a cheese.
  • a spinning device for producing a thread
  • a bobbin holder having winding device for winding the thread onto a cheese.
  • Partly or fully automatic spinning machines are known from the prior art in various designs.
  • 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 cheese, and a variety of other elements for producing the thread and for handling the thread produced and the thread presented Fiber material.
  • Essential components for the production of 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.
  • the DE 10 2004 044 551 A1 suggested dividing the consulting activity that arises in each case into manual and mechanical work steps. In this way, the operating personnel can carry out the work steps to be carried out manually at workplaces that have already been shut down, while an automatic maintenance device carries out the work steps to be carried out by machine in parallel. In the case of a centrally driven spinning machine in which the lot change is carried out simultaneously at a large number of workplaces, a considerable time saving can be achieved as a result.
  • the object of the present invention is to propose a method for operating a spinning machine as well as a spinning machine which enables batches to be changed as quickly as possible, even at individual workplaces.
  • each of the workplaces has a spinning device for producing a thread and a winding device having a bobbin holder for winding up the thread a cheese on.
  • the current batch is displayed at the workstations, in particular by a color display.
  • the operating personnel can quickly see which workplaces are producing the same yarn batch. This also contributes to the fact that the operating personnel is supported in establishing a meaningful sequence for the processing of manual maintenance. In addition, this allows the operating personnel to more easily 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 relevant yarn section.
  • the display of the need to carry out at least one manual maintenance activity at the work site which has reached the end of the batch can in principle take place 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 job.
  • the occupancy states of the bobbin holder can be, for example, "empty”, "occupied” or “incorrectly occupied”. If there is now a discrepancy between the occupancy state of the bobbin holder and the display of the current batch at the work station, this signals the need to carry out at least one manual maintenance activity to the operating personnel. In this case, the manual maintenance requirement is displayed by components of the respective work stations themselves.
  • a supply position for empty tubes is provided at the work site, it is alternatively or additionally also possible that the need to carry out at least one manual maintenance activity is indicated by an occupancy status of the supply position for empty tubes.
  • Occupancy states empty", "occupied” or “incorrectly occupied” are conceivable. If, for example, there is a discrepancy between the occupancy status of the supply position, where there is already an empty tube from the new batch, and the display of the current, old batch at the work site, this in turn signals the need to carry out at least one manual maintenance activity to the operating personnel.
  • a wound cheese is automatically removed from a batch that is still current and the need to carry out at least one manual maintenance activity is indicated by an empty bobbin holder.
  • the operating personnel can use the empty bobbin holder to recognize that retooling work for a lot change has to be carried out at this work station, because otherwise a new empty tube from the still current lot would have been inserted automatically.
  • an empty tube of a new batch can be provided in the supply position at the work station which has reached the end of the batch and for the need to carry out at least one manual maintenance activity to be indicated by the empty tube made available. Since at the same time the bobbin holder still has the occupancy status "empty", the operating personnel can recognize that manual maintenance activities have to be carried out at this workstation, because otherwise the new empty tube would have been automatically inserted. It is also possible that an empty tube of the new lot has been provided in the supply position, but the current, old lot is displayed at the work station. The operating personnel can also recognize from this discrepancy that there is a need to carry out at least one manual maintenance activity.
  • a wound cheese is automatically removed from a batch that is still current 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 assigned bobbin holder, since the empty tube already inserted in the new batch does not match the display of the batch that is still current at the work site.
  • the need to carry out at least one manual maintenance activity is indicated by a combination of the three different indicators, namely the occupancy status of the bobbin 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 bobbin 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 particular a graphic display, assigned to the work station.
  • an optical display element in particular a graphic display
  • the operating personnel do not have to draw conclusions from the prevailing constellation at the workplace, as in the first two explanations, 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 lamp or a specific flashing light, which of course have to differ from the displays of other states at the workplace.
  • the operating personnel must know exactly the meaning of the different colors and / or flashing symbols in order to be able to assign them different states on the spinning machine.
  • the optical display element is a graphic display, the operator can be informed clearly and unmistakably in the form of texts or symbols that there is a need to carry out at least one manual maintenance activity.
  • At least one first manual maintenance activity to be performed is displayed by the display element.
  • the input device is a button on the display.
  • the optical display element and the input device are combined in a touchscreen in this case.
  • a further manual maintenance activity to be carried out is displayed by the display element.
  • the operator therefore has to confirm that the first manual maintenance activity has been carried out and then receives precise information as to which further specific maintenance activity is to be carried out. Of course, this can also be repeated several times, so that the operator is instructed step by step to carry out the necessary manual maintenance activities. It is also advantageous here if the execution of the respective maintenance activity is confirmed by means of a button on the graphic display.
  • the operator can be given the replacement of the spinning rotor as the first maintenance activity to be performed and the replacement of the fiber material as the second maintenance activity.
  • the provision of suitable empty tubes and, if necessary, an exchange of the extraction nozzle can also be specified.
  • a spinning material exchange and / or a fiber material exchange is indicated as a manual maintenance activity to be carried out.
  • the operating personnel can in turn immediately recognize from the display "Spinning material exchange” or “Fiber material exchange” that several manual maintenance activities are to be carried out and then preferentially treat these particularly complex jobs.
  • the first and / or the further manual maintenance activity is displayed in the form of a text display and / or in the form of a graphic symbol.
  • the new lot is also displayed in addition to the current lot at the relevant job, in particular is indicated by a color display.
  • a color display As a result, the operator can already see before the end of the batch of the respective work station that complex conversion work is pending and that all the new spinning equipment, fiber materials, etc. required are already ready. The time required to change batches at the workplace can be reduced even further.
  • the new batch is started at the work station, preferably started independently by the work station.
  • a spinning machine producing cross-wound bobbins in particular an open-end rotor spinning machine, with a large number of similar workplaces 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 cheese.
  • the spinning machine also has a control device and a display element for carrying out the method described above.
  • FIG Figure 1 shows a schematic front view of a spinning machine 1 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, which are not designated in any more detail 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, acts as an opening roller 8 (see FIG Figure 1 ) is trained.
  • each of the work stations 2 has a spinning device 3 for producing a thread 6, a pull-off device 9 for pulling off the produced thread 6 and a winding device 4 for winding the produced thread 6 onto a cheese 10.
  • the jobs 2 are designed as at least partially self-sufficient jobs.
  • 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.
  • the workstations 2 can independently rectify at least some of the malfunctions occurring during operation without the need for an operating robot or the intervention of an operator. Therefore, further components, not shown here, such as handling organs and maintenance organs, are arranged at the work stations 2.
  • a display element 12 is provided at each of the workplaces 2, which can display, for example, various operating states of the workplaces 2 or the yarn section produced in each case. As an alternative to the representation shown, it is also conceivable that a display element 12 is assigned to two work stations 2 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 the feed device and a spinning rotor 13 as the spinning element of the spinning device 3.
  • the thread 6 produced in the spinning rotor 13 is drawn off via a draw-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. Fig. 9 and 10 ) is added, which can then be wound into a cheese 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 and other handling organs and maintenance organs of work stations 2 are shown in FIG Figure 2 also not shown.
  • the manual maintenance requirement is preferably displayed by an optical display element 12, as follows on the basis of FIG Figures 3 to 8 is explained.
  • an optical display element 12 it is also possible to indicate the need to carry out at least one manual maintenance activity by means of an occupancy status of the bobbin holder 5, as is shown in FIG Figures 9 and 10 is described.
  • Figure 3 shows a view of an optical display element 12, which in the present case is designed as a graphic display 15.
  • Figure 3 shows the display 15 with a first display that shows a regular operating state of the work station 2.
  • the current batch here designated by "A”
  • A is displayed by a color display 20 (shown here with light dots).
  • the regular operating status itself is indicated by an easily understandable graphic symbol 16.
  • the display element 12 is assigned an input device 17 by means of which the Operator can make inputs and communicate with a control unit (not shown here) of workstation 2 and / or a central control unit (also not shown).
  • 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 correspondingly formed by different buttons 18 of the display 15.
  • the display 15 has, for example, a button 18 for calling up information. By pressing this button, the operator can access the menu of the control unit of work station 2 and make various settings there.
  • Figure 4 shows a view of the display element 12 or the display 15, with which a need to carry out at least one manual maintenance activity is displayed when the end of the batch of the relevant work station 2 is reached.
  • the current game is still displayed by the color display 20.
  • the need to carry out at least one manual maintenance activity is indicated here by a further, easily understandable graphic symbol 16. Using this symbol, the operating personnel can very quickly recognize that manual activities are to be carried out at this workstation 2 and thereby preferentially process these workstations 2 or better plan the maintenance of the workstations concerned.
  • the display of the need to carry out at least one manual maintenance activity is again designed as a button 18, which can be seen in the present case both from the frame surrounding the button 18 and from the request for actuation by the tick. If the operator now actuates this button 18, he receives more precise information about which specific maintenance activities are to be carried out in a subsequent display.
  • Figure 5 now shows another display of the display 15, which the operator can see after pressing button 18 of the previous display ( Figure 4 ) or, in the general case after actuation of the input device 17, the indicates manual maintenance activity to be performed.
  • the task "Check spinning components" is displayed in the form of a display text. As a result, and possibly through subsequent displays, the operator receives the information that he must check the spinning equipment and replace it if necessary.
  • the same displays can be used both for malfunctions in regular spinning operation, which lead to a standstill of the workstation 2, as well as when maintenance is required due to an upcoming batch change.
  • the operator only has to be shown the need to carry out at least one manual maintenance activity and he is then guided through the menu and given step-by-step concrete instructions. The operator therefore does not have to differentiate between disruptions in regular operation and lot changes and think about which manual maintenance activities he has to carry out in which case, but only has 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 again contain a button 18 by means of which the operator must confirm the maintenance activity after the maintenance activity has been carried out.
  • another required manual maintenance activity can optionally be displayed, the execution of which the operator must also confirm again, whereupon another required manual maintenance activity may be required Maintenance activity is displayed.
  • the workstation 2 can independently resume production and start the new batch.
  • the operating personnel can see at a glance that the need to carry out at least one manual maintenance activity relates to a lot change with spinning material exchange and can treat these workplaces 2 with preference.
  • This is particularly advantageous if specially trained personnel are required for such a spinning device exchange.
  • the staff can thus immediately recognize whether simple manual maintenance work is to be carried out or a spinning component exchange, for which specially trained staff 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 status of the reel holder 5 or the occupancy status of a supply position 22 for empty tubes 11.

  • 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 inserting an empty tube 11 of the new batch into the bobbin holder 5, as can be seen from the dark dotted color of the empty tube.
  • the display element 12 still shows the color display 20 of the just ended, still current game.
  • the inserted empty tube 11 therefore does not match the displayed section, so that the bobbin holder 5 has the "incorrect assignment" state.
  • the operating personnel can therefore use the stationary work station 2 and the incorrect assignment of the bobbin holder to recognize that a lot change is pending and manual activities must be carried out.
  • the operating personnel can now, in turn, use the "empty" occupancy status and the display of the current batch to recognize that a batch change is pending and manual activities are to be carried out.
  • Figure 11 shows a work station 2, which also has a storage position for empty tubes 11, the need to carry out at least one manual maintenance activity is indicated by the empty tube 11 provided.
  • Workstation 2 has again reached the end of the batch and has already been shut down. Just like with Fig. 9 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 in that an empty tube 11 of the new batch (dark dotted color) has been made available in the supply position 22, but has not yet been placed in the bobbin holder 5.
