Definitions

  • the present invention relates to a method for cleaning a textile machine consisting of a plurality of identical work stations, a cleaning request being made for a work station and the work station to be cleaned being approached and cleaned by a mobile cleaning device.
  • the invention also relates to a textile machine with a plurality of identical work stations, a mobile cleaning device and a control device.
  • the DE 33 08 248 A1 describes an OE friction spinning machine with a large number of juxtaposed spinning units, a maintenance trolley being provided which can be moved in the longitudinal direction of the machine and can be delivered to a spinning unit for cleaning the rollers of this spinning unit.
  • a spinning machine system with several open-end spinning machines and with at least one movable maintenance device is disclosed, which can be delivered to each spinning unit of the individual open-end spinning machines and which contains a program switch with which the switching sequences and switching times of the drives of the functional elements are controlled, which the individual steps of a Carry out maintenance work.
  • the DE 195 29 654 A1 relates to a pneumatic cleaning device for the spinning positions of an open-end spinning machine.
  • the cleaning device is arranged on the sliver intake arm of a service unit and, together with the fiber sliver intake arm, can be pivoted between a rest position and an operating position.
  • a maintenance device is also movably arranged, on which cleaning elements are provided, which can be delivered to the surrounding area of an opening roller and thus clean it.
  • the DE 101 48 330 A1 describes a method for controlling the travel movements of a maintenance device on a textile machine, wherein the maintenance device maintains and / or controls a work area assigned to it with a plurality of processing points of the textile machine.
  • the object of the present invention is to propose a method for cleaning a textile machine consisting of a plurality of identical work stations that takes into account the different levels of soiling of the individual work stations.
  • a method for cleaning a textile machine consisting of a plurality of identical work stations can be, for example, a rotor spinning machine, an air-jet spinning machine, a ring spinning machine or a winding machine or another textile machine that has a series of identical workplaces and is cleaned by a mobile cleaning device.
  • a spinning machine a work station is understood to be a unit that spins a sliver coming from a can into a thread and winds the thread on a bobbin.
  • a cleaning request is made for a job. This can be done both by the work station itself and by a control device of the textile machine. When a cleaning request has been made, the work site is approached and cleaned by a mobile cleaning device.
  • the cleaning request is made as a function of events that have occurred at the respective work stations since the last cleaning process. These events are an indication of the soiling of the workplace that has occurred since the last cleaning process.
  • the method therefore takes into account the different levels of soiling of the individual workplaces.
  • the events advantageously include predetermined malfunctions, predetermined combinations of measured values, preferably in the form of quality measured values, piecing processes, changing bobbins and / or changing cans.
  • the faults include, for example, thread breaks or cleaner cuts. All or only some predetermined disturbances can be evaluated as events.
  • Measured values, preferably quality measured values are, for example, the thickness or the color of the thread. Certain combinations of such measured values indicate a need for cleaning at a work site and can consequently also be assessed as events.
  • Attachment processes are understood to mean both the connection of two loose thread ends after a thread break or cleaner cut and the attachment of a thread to an empty or partially wound bobbin. Bobbin and can changes show directly how much yarn or textile has been processed.
  • the work places lying on the way of the cleaning device are also cleaned depending on events that have occurred at the respective work places since the last cleaning process.
  • This dependency is chosen in such a way that the workplaces lying on the way of the cleaning device are cleaned even if they have not yet made a cleaning request themselves, but if, based on the events that have already occurred, it is foreseeable that they will soon make a cleaning request. Thus become unnecessarily frequent or long journeys of the cleaning device are avoided, which increases the efficiency of the cleaning device.
  • the dependency is the exceeding of a, preferably weighted, number of events.
  • a can change indicates that a relatively large amount of yarn has been processed and that, accordingly, severe contamination has been caused.
  • the weighting factor for a can change is therefore relatively high.
  • a single piecing process causes only a relatively low level of soiling, so that the weighting factor for a piecing process should be selected to be relatively small. If a certain threshold value of weighted events is exceeded, this indicates that a certain level of pollution has been reached. A cleaning request is then made.
  • a somewhat smaller threshold value is selected in order to determine whether or not they are also cleaned during the cleaning trip. In this way, these workplaces can be cleaned even if they have not yet fully reached the threshold value that would lead to a cleaning request being made.
  • the events are weighted according to their distance from the respective job.
  • Most of the pollution is usually caused by the spinning operation at the respective work site itself.
  • the spinning operation at the neighboring workplaces also causes a certain amount of soiling of a work place, but less with increasing distance.
  • the dependency is a predetermined sequence of events. If, for example, a certain number of piecing processes is exceeded between two bobbin changes, it can be assumed that there is an error. This error could come from an excessively polluted workplace, but could also have other causes. Placing a cleaning request after a certain number of batching processes in a row thus serves to eliminate possible contamination as the cause of the error. If many preparation processes continue to be carried out one after the other after cleaning, then the cause of the error is probably different. In this case, a maintenance device must maintain the work site or operating personnel investigate the cause of the accumulation of preparation processes.
  • a cleaning request is advantageously only made for current jobs. If a job is not running for a longer period of time, events at neighboring jobs could mean that a cleaning request is made anyway. However, it's only worth making a cleaning request if the job is up and running again soon. Since this cannot be foreseen for jobs that are not running for a long time, it is more efficient if jobs that are not running do not have any cleaning requirements.
  • the mobile cleaning device is operated as a separate cleaning unit.
  • the cleaning device can then be moved largely independently of other maintenance devices along the textile machine and thus to the individual workplaces and does not have to coordinate the processing of the cleaning requirements with other maintenance requirements.
  • the cleaning device is operated as part of a larger movable maintenance device.
  • the cleaning device does not need a separate drive and there is no need to pay attention to possible collisions between the cleaning device and the larger maintenance device (the maintenance device being designed, for example, as a service robot that carries out the above-mentioned attachment processes).
  • the cleaning process is carried out by the cleaning device that has a lower workload. In this way, an adjustment of the workload is achieved and the efficiency of the cleaning devices is increased.
  • the cleaning process is carried out by that cleaning device which is closer to the job for which the cleaning request was made. With this strategy, unnecessarily long journeys for the cleaning devices are avoided and the cleaning can be carried out more quickly.
  • the textile machine also has a mobile cleaning device and a control device.
  • the control device is designed to make cleaning requests for workstations and the cleaning device is designed to approach and clean a workstation for which a cleaning request has been made.
  • the control device is designed in such a way that it cleans the textile machine in accordance with the aspects described above.
  • the control device therefore makes cleaning requests as a function of events that have occurred at the respective workplaces since the last cleaning process. These events are an indication of the soiling of the workplace that has occurred since the last cleaning process.
  • the control device is thus designed to take into account the different levels of soiling of the workplaces when making the cleaning requirements.
  • the mobile cleaning device is designed as a separate cleaning unit.
  • the cleaning device can then be moved along the textile machine largely independently of other maintenance devices and does not have to coordinate the processing of the cleaning requirements with other maintenance requirements.
  • the cleaning device is designed as part of a larger mobile maintenance device. This saves a separate drive for the cleaning device and there is no need to pay attention to possible collisions between the cleaning device and the larger maintenance device.
  • Figure 1 shows a mobile cleaning device 1 in front of a work station 2 of a textile machine.
  • a work station 2 of a textile machine In this case it is a rotor spinning machine.
  • the method according to the invention can, however, in principle be applied to other spinning machines or generally to any textile machine with a plurality of identical work stations 2 and a mobile cleaning device 1.
  • the work station 2 has a spinning unit 3 which spins a sliver 5 coming from a can 4 into a thread 6.
  • the thread 6 will then taken over by a pair of take-off rollers 7 and wound onto a spool 9 by means of a traversing element 8.
  • Events such as a change of the can 4, a change of the bobbin 9 or an attachment of the thread 6 are transmitted from the work station 2 to a control device of the textile machine. If a predetermined threshold value of weighted events for the job 2 is reached or exceeded, the control device requests the cleaning of the job 2 by the cleaning device 1.
  • the cleaning device 1 then travels along rails 10 to the work station 2, where it is positioned exactly by means of a positioning element 11 assigned to the work station.
  • the cleaning itself is carried out by a suction nozzle 12 in this exemplary embodiment.
  • the suction trunk 12 is connected to the chassis 16 of the cleaning device 1 via several arms 13, 14, 15.
  • the suction tube 12 and the arms 13, 14 can be pivoted about horizontal axes 17, 18, 19 and the suction tube can also be pivoted about the vertical axis 20. In this way, the suction pipe 12 can be moved to the objects of the work station 2 to be suctioned off.
  • the method described here is not limited to cleaning by suctioning off dirt; Rather, other cleaning methods, for example with compressed air or with mechanical cleaning elements, are also conceivable.
  • Figure 2 shows a plan view of a textile machine 21 with a plurality of work stations 2 and two cleaning devices 1.
  • the cleaning devices can be moved along the rails 10.
  • the workplaces 2 are assigned to one of three areas: an exclusive area EB1, which is on a machine side of the textile machine 21 is located, an exclusive area EB2, which is located on the other side of the machine, and an overlapping area Ü.
  • the work stations 2 send information about events such as can changes, bobbin changes and / or piecing processes to a control device 23 arranged at the machine end 22. These events are provided with a weighting factor by the control device 23. The weighting factor is greater, the greater the contamination associated with the event. For each job 2, a sum of the weighted events is formed. Events that occurred at neighboring workplaces 2 are also counted, but these events are given a further weighting factor, the smaller the greater the distance from the event to workstation 2.
  • a cleaning request is made for this job 2. If workstation 2 is in the exclusive area EB1, which is the in Figure 2 is assigned to the upper cleaning device 1, the cleaning device 1 drives to the work station 2 for which the cleaning request was made. The in Figure 2 lower cleaning device 1 responsible for the workplaces 2 in the exclusive area EB2. However, if the cleaning request is made for a job in the overlap area U, the cleaning process is carried out by the cleaning device 1, which has the lower workload.
  • the weighted event total for the cleaned job 2 is set to zero and the counting starts from the beginning.
