Definitions
- the present invention relates to a method for cleaning a textile machine consisting of a plurality of identical workstations, wherein a cleaning request for a workstation is made and the workstation to be cleaned is started up and cleaned by a mobile cleaning device.
- the invention further relates to a textile machine with a plurality of identical work stations, a mobile cleaning device and a control device.
- the object of the present invention is therefore to propose a method for cleaning a textile machine consisting of a plurality of identical workstations, which takes into account the different soiling of the individual workstations.
- the object is achieved by a method for cleaning a textile machine and a textile machine with the features of the independent claims.
- a method for cleaning a textile machine consisting of a plurality of identical workstations This may be, for example, a rotor spinning machine, an air spinning machine, a ring spinning machine or even a winder or other textile machine, which has a juxtaposition of the same jobs and is cleaned by a mobile cleaning device.
- a workstation is understood as meaning a unit which spun a fiber sliver coming from a jug into a yarn and wound up the yarn on a spool.
- a cleaning request is made for a job. This can be done both by the workstation itself and by a control device of the textile machine. If a cleaning request has been made, the workstation is started up and cleaned by a mobile cleaning device.
- the cleaning requirement is set as a function of events occurring at the respective work stations since the last cleaning process. These events are an indication of the pollution of the workplace since the last cleaning process.
- the method thus takes into account the different pollution of the individual jobs.
- the events include predetermined disturbances, predetermined combinations of measured values, preferably in the form of quality measured values, piecing operations, the change of bobbins and / or change of cans.
- the disorders include, for example, thread breaks or cleaner cuts. It can all or just a few predetermined disturbances be counted as events.
- Measured values, preferably quality measured values are, for example, the thickness or the color of the thread. Certain combinations of such measurements indicate a need for cleaning a job and can therefore also be considered as events.
- Under piecing is understood here as the joining of two loose thread ends after a thread break or cleaner cut and the attachment of a thread on an empty or partially wound coil. Coil and can change directly indicate how much yarn or textile was processed.
- the dependence is the exceeding of a, preferably weighted, number of events. It shows, for example a can change that a relatively large amount of yarn was processed and consequently a strong pollution was caused.
- the weighting factor for a can change is therefore relatively high.
- a single piecing process causes only a relatively weak contamination, so that the weighting factor for a piecing process is relatively small. If then a certain threshold of weighted events is exceeded, this indicates that a certain level of pollution has been reached. A cleaning request will be made.
- a slightly lower threshold is selected to determine whether or not they will be cleaned during the cleaning run. So these jobs can also be cleaned, if they have not quite reached the threshold, which would lead to a request cleaning.
- the events are weighted according to their distance to the respective job.
- most of the pollution is usually caused by the spinning operation at the work site itself.
- the spinning operation at the neighboring jobs causes a certain, but with increasing distance lower, pollution of a job.
- the greater the distance of the work site at which an event occurs, the observed work site the smaller the weighting factor is chosen.
- the dependency is a predetermined sequence of events. If, for example, a certain number of piecing processes is exceeded between two bobbin changes, then it can be assumed that an error has occurred. This error could be from too dirty Work, but could have other causes as well.
- the provision of a cleaning request after a certain number of piecing operations in succession thus serves to remedy a possible contamination as the cause of the error. If, after cleaning, many attachments continue to be performed consecutively, then the cause of the error is probably a different one. In that case, a maintenance device must wait for the job or operators must investigate the cause of the accumulation of attachments.
- this job can also be contaminated by dust or fibers contained in the ambient air. If a predetermined time has already elapsed since the last cleaning of the workstation, it is advantageous if a cleaning request for this workstation is made to ensure that the corresponding workstations are never excessively contaminated at any time.
- a cleaning request is made only for current jobs. If a job does not run for an extended period of time, events at neighboring jobs could still cause a clean request. However, it is only worthwhile to ask for a cleaning request if the workstation soon resumes. Since this can not be foreseen for jobs that are not running for a long time, it is more efficient when non-current jobs do not require cleaning.
- the mobile cleaning device is operated as a separate cleaning unit. Then, the cleaning device can be moved largely independently of other maintenance devices along the textile machine and thus to the individual jobs and does not coordinate the execution 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 require a separate drive and care must be taken not to possible collisions between the cleaning device and the larger maintenance device (the maintenance device is formed, for example, as a service robot, which performs the aforementioned Ansetzvor bland).
- the cleaning operation is performed by the cleaning device having a lower workload.
- an adaptation of the workloads is achieved and increases the efficiency of the cleaning devices.
- the cleaning request for a job is placed in the overlap area, it may also be advantageous if the cleaning operation is performed by the cleaning device that is closer to the work site for which the cleaning request was made. With this strategy unnecessarily long travel distances of 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 provide cleaning requirements for jobs and the cleaning device is adapted to approach and clean a job for which a cleaning request has been made.
- control device is designed such that it cleans the textile machine according to the aspects described so far.
- the control device thus provides cleaning requirements as a function of events occurring at the respective work stations since the last cleaning process. These events are an indication of the pollution of the workplace since the last cleaning process.
- the control device is thus designed to take into account the different contamination of the jobs when setting the cleaning requirements.
- the mobile cleaning device is designed as a separate cleaning unit. Then the cleaning device can be moved largely independently of other maintenance devices along the textile machine and does not have to coordinate the execution of the cleaning requirements with other maintenance requirements.
- the cleaning device is designed as part of a larger mobile maintenance device.
- a separate drive for the cleaning device is saved and there is no need to pay attention to possible collisions between the cleaning device and the larger maintenance device.
- FIG. 1 shows a mobile cleaning device 1 in front of a workstation 2 of a textile machine.
- This is in this case a rotor spinning machine.
- the method according to the invention is in principle applicable to other spinning machines or in general any textile machine with a plurality of identical work stations 2 and a mobile cleaning device 1.
- the workstation 2 has a spinning unit 3 which spins a sliver 5 coming from a can 4 into a yarn 6.
- the thread 6 is then taken over by a take-off roller pair 7 and wound by means of a traversing element 8 on a spool 9.
- Events such as a change of the can 4, a change of the coil 9 or a setting of the thread 6 are transmitted from the workstation 2 to a control device of the textile machine. If a predetermined threshold of weighted events for workstation 2 has been reached or exceeded, the control device requests the cleaning of the workstation 2 by the cleaning device 1.
- the cleaning device 1 then travels along rails 10 to the workstation 2, where it is exactly positioned by means of a positioning element 11 assigned to the workstation.
- the cleaning itself is carried out in this embodiment of a proboscis 12.
- the suction pipe 12 is connected via several arms 13, 14, 15 to the chassis 16 of the cleaning device 1.
- the suction pipe 12 and the arms 13, 14 are pivotable about horizontal axes 17, 18, 19 and the suction pipe in addition about the vertical axis 20.
- the proboscis 12 can be moved to the objects to be sucked the job 2.
- the method described here is not limited to a cleaning by suction of dirt; Rather, other cleaning methods, for example with compressed air or with mechanical cleaning elements, conceivable.
- FIG. 2 shows a plan view of a textile machine 21 with a plurality of jobs 2 and two cleaning devices 1.
- the cleaning devices are movable along the rails 10.
- the work sites 2 are assigned to one of three areas: an exclusive area EB1 located on a machine side of the textile machine 21, an exclusive area EB2 located on the other machine side, and an overlapping area Ü.
- the work stations 2 send information about events such as can changing, bobbin changing and / or piecing operations to a control device 23 arranged at the machine end 22. These events are provided by the control device 23 with a weighting factor. The weighting factor is greater, the greater the pollution associated with the event is. For each job 2, a sum of the weighted events is formed. In the process, events that have occurred at neighboring workstations 2 are also counted, but these events are provided with a further weighting factor, which is the smaller the greater the distance from the event to the workstation 2.
- a cleaning request for this job 2 is made. If the job 2 is in the exclusive area EB1, the one in FIG. 2 is assigned to the upper cleaning device 1, so the cleaning device 1 moves to the job 2, for which the cleaning request has been made. Likewise, the in FIG. 2 lower cleaning device 1 responsible for the jobs 2 in the exclusive area EB2. However, if the cleaning request is made for a job in the overlapping area Ü, the cleaning process is performed by the cleaning device 1, which has the lower workload.
- the weighted event sum for clean job 2 is set to zero and counting starts again.

Description
Die vorliegende Erfindung betrifft ein Verfahren zum Reinigen einer aus einer Mehrzahl von gleichen Arbeitsstellen bestehenden Textilmaschine, wobei eine Reinigungsanforderung für eine Arbeitsstelle gestellt wird und die zu reinigende Arbeitsstelle durch eine fahrbare Reinigungsvorrichtung angefahren und gereinigt wird. Die Erfindung betrifft ferner eine Textilmaschine mit einer Mehrzahl von gleichen Arbeitsstellen, einer fahrbaren Reinigungsvorrichtung und einer Steuereinrichtung.The present invention relates to a method for cleaning a textile machine consisting of a plurality of identical workstations, wherein a cleaning request for a workstation is made and the workstation to be cleaned is started up and cleaned by a mobile cleaning device. The invention further relates to a textile machine with a plurality of identical work stations, a mobile cleaning device and a control device.
Die Reinigung von Arbeitsstellen von Textilmaschinen durch fahrbare Reinigungsvorrichtungen ist wohlbekannt. Dabei gibt es unterschiedliche Verfahren, nach welchen Gesichtspunkten die Reinigungsvorrichtung die einzelnen Arbeitsstellen anfährt. So wird in der
Aufgabe der vorliegenden Erfindung ist es somit, ein Verfahren zum Reinigen einer aus einer Mehrzahl von gleichen Arbeitsstellen bestehenden Textilmaschine vorzuschlagen, das die unterschiedliche Verschmutzung der einzelnen Arbeitsstellen berücksichtigt.The object of the present invention is therefore to propose a method for cleaning a textile machine consisting of a plurality of identical workstations, which takes into account the different soiling of the individual workstations.
Die Aufgabe wird gelöst durch ein Verfahren zum Reinigen einer Textilmaschine und eine Textilmaschine mit den Merkmalen der unabhängigen Patentansprüche.The object is achieved by a method for cleaning a textile machine and a textile machine with the features of the independent claims.
Vorgeschlagen wird ein Verfahren zum Reinigen einer aus einer Mehrzahl von gleichen Arbeitsstellen bestehenden Textilmaschine. Dabei kann es sich beispielsweise um eine Rotor-Spinnmaschine, eine Luftspinnmaschine, eine Ringspinnmaschine oder auch um eine Spulmaschine oder eine andere Textilmaschine handeln, die eine Aneinanderreihung von gleichen Arbeitsstellen aufweist und von einer fahrbaren Reinigungsvorrichtung gereinigt wird. Unter einer Arbeitsstelle versteht man dabei für den Fall einer Spinnmaschine eine Einheit, die ein aus einer Kanne kommendes Faserband zu einem Faden verspinnt und den Faden auf einer Spule aufwickelt.A method is proposed for cleaning a textile machine consisting of a plurality of identical workstations. This may be, for example, a rotor spinning machine, an air spinning machine, a ring spinning machine or even a winder or other textile machine, which has a juxtaposition of the same jobs and is cleaned by a mobile cleaning device. In the case of a spinning machine, a workstation is understood as meaning a unit which spun a fiber sliver coming from a jug into a yarn and wound up the yarn on a spool.
Bei dem Verfahren wird eine Reinigungsanforderung für eine Arbeitsstelle gestellt. Dies kann sowohl durch die Arbeitsstelle selbst als auch durch eine Steuereinrichtung der Textilmaschine erfolgen. Wenn eine Reinigungsanforderung gestellt wurde, wird die Arbeitsstelle durch eine fahrbare Reinigungsvorrichtung angefahren und gereinigt.In the method, a cleaning request is made for a job. This can be done both by the workstation itself and by a control device of the textile machine. If a cleaning request has been made, the workstation is started up and cleaned by a mobile cleaning device.
Erfindungsgemäß wird die Reinigungsanforderung in Abhängigkeit von an den jeweiligen Arbeitsstellen seit dem letzten Reinigungsvorgang angefallenen Ereignissen gestellt. Diese Ereignisse sind dabei ein Indiz für die seit dem letzten Reinigungsvorgang angefallene Verschmutzung der Arbeitsstelle. Das Verfahren berücksichtigt also die unterschiedliche Verschmutzung der einzelnen Arbeitsstellen.According to the invention, the cleaning requirement is set as a function of events occurring at the respective work stations since the last cleaning process. These events are an indication of the pollution of the workplace since the last cleaning process. The method thus takes into account the different pollution of the individual jobs.
Vorteilhafterweise zählen zu den Ereignissen vorbestimmte Störungen, vorbestimmte Kombinationen von Messwerten, vorzugsweise in Form von Qualitätsmesswerten, Ansetzvorgänge, der Wechsel von Spulen und/oder Wechsel von Kannen. Zu den Störungen zählen beispielsweise Fadenbrüche oder Reinigerschnitte. Dabei können alle oder auch nur einige vorbestimmte Störungen als Ereignisse gewertet werden. Messwerte, vorzugsweise Qualitätsmesswerte, sind beispielsweise die Dicke oder die Farbe des Fadens. Bestimmte Kombinationen von solchen Messwerten zeigen dabei einen Reinigungsbedarf an einer Arbeitsstelle an und können folglich ebenfalls als Ereignisse gewertet werden. Unter Ansetzvorgängen versteht man dabei sowohl das Verbinden von zwei losen Fadenenden nach einem Fadenbruch bzw. Reinigerschnitt als auch das Ansetzen eines Fadens auf eine leere oder teilweise bewickelte Spule. Spulen- und Kannenwechsel zeigen dabei direkt an, wie viel Garn bzw. Textil bearbeitet wurde. Da pro bearbeiteter Garn- oder Textilmenge auch eine gewisse Verschmutzung anfällt, sind Spulen- und Kannenwechsel gute Indikatoren für die angefallene Verschmutzung. Auch bei jedem Ansetzvorgang fällt Schmutz an bzw. wird Schmutz aufgewirbelt. Daher ist auch dies ein guter Indikator für die Verschmutzung der Arbeitsstelle. Diese Liste an Ereignissen ist aber nicht ausschließlich: je nach Textilmaschine können auch noch andere Ereignisse berücksichtigt werden, beispielsweise bestimmte Wartungsvorgänge durch eine Wartungsvorrichtung oder der Austausch von Verschleißteilen.Advantageously, the events include predetermined disturbances, predetermined combinations of measured values, preferably in the form of quality measured values, piecing operations, the change of bobbins and / or change of cans. The disorders include, for example, thread breaks or cleaner cuts. It can all or just a few predetermined disturbances be counted as events. Measured values, preferably quality measured values, are, for example, the thickness or the color of the thread. Certain combinations of such measurements indicate a need for cleaning a job and can therefore also be considered as events. Under piecing is understood here as the joining of two loose thread ends after a thread break or cleaner cut and the attachment of a thread on an empty or partially wound coil. Coil and can change directly indicate how much yarn or textile was processed. Since per processed yarn or textile amount also a certain amount of contamination accumulates, bobbin and can change are good indicators of the pollution incurred. Even with every piecing process, dirt or dirt is whirled up. Therefore, this too is a good indicator of job pollution. However, this list of events is not exclusive: depending on the textile machine, other events may also be taken into account, for example certain maintenance operations by a maintenance device or the replacement of wearing parts.
Vorteilhaft ist es, wenn bei einer von einer Arbeitsstelle angeforderten Reinigungsfahrt die auf dem Weg der Reinigungsvorrichtung liegenden Arbeitsstellen in Abhängigkeit von an den jeweiligen Arbeitsstellen seit dem letzten Reinigungsvorgang angefallenen Ereignissen auch gereinigt werden. Dabei wird diese Abhängigkeit so gewählt, dass die auf dem Weg der Reinigungsvorrichtung liegenden Arbeitsstellen auch schon gereinigt werden, wenn sie selbst noch keine Reinigungsanforderung gestellt haben, aber wenn auf Grund der bereits angefallenen Ereignisse abzusehen ist, dass sie bald eine Reinigungsanforderung stellen werden. Somit werden unnötig häufige bzw. weite Fahrten der Reinigungsvorrichtung vermieden, was die Effizienz der Reinigungsvorrichtung steigert.It is advantageous if, during a cleaning trip requested by a workstation, the workstations lying on the way of the cleaning device are also cleaned as a function of events occurring at the respective workstations since the last cleaning process. In this case, this dependence is chosen so that lying on the way the cleaning device jobs are already cleaned even if they have not yet made a cleaning request, but if it is foreseen due to the already incurred events that they will soon make a cleaning request. Thus unnecessarily frequent or long trips of the cleaning device are avoided, which increases the efficiency of the cleaning device.
Von Vorteil ist es, wenn die Abhängigkeit das Überschreiten einer, vorzugsweise gewichteten, Anzahl von Ereignissen ist. Dabei zeigt beispielsweise ein Kannenwechsel an, dass eine relativ große Menge Garn verarbeitet wurde und dementsprechend eine starke Verschmutzung verursacht wurde. Der Gewichtungsfaktor für einen Kannenwechsel ist also relativ hoch. Dagegen verursacht ein einzelner Ansetzvorgang nur eine relativ schwache Verschmutzung, so dass der Gewichtungsfaktor für einen Ansetzvorgang relativ klein zu wählen ist. Wird dann ein bestimmter Schwellenwert von gewichteten Ereignissen überschritten, zeigt dies an, dass ein bestimmter Grad an Verschmutzung erreicht wurde. Es wird daraufhin eine Reinigungsanforderung gestellt.It is advantageous if the dependence is the exceeding of a, preferably weighted, number of events. It shows, for example a can change that a relatively large amount of yarn was processed and consequently a strong pollution was caused. The weighting factor for a can change is therefore relatively high. In contrast, a single piecing process causes only a relatively weak contamination, so that the weighting factor for a piecing process is relatively small. If then a certain threshold of weighted events is exceeded, this indicates that a certain level of pollution has been reached. A cleaning request will be made.
Für Arbeitsstellen, die - wie oben beschrieben - auf dem Weg der Reinigungsvorrichtung liegen, wird ein etwas kleinerer Schwellenwert gewählt, um festzulegen, ob sie bei der Reinigungsfahrt mitgereinigt werden oder nicht. So können diese Arbeitsstellen auch schon gereinigt werden, wenn sie noch nicht ganz den Schwellenwert erreicht haben, der zum Stellen einer Reinigungsanforderung führen würde.For workstations that are on the way of the cleaning device as described above, a slightly lower threshold is selected to determine whether or not they will be cleaned during the cleaning run. So these jobs can also be cleaned, if they have not quite reached the threshold, which would lead to a request cleaning.
Es ist auch von Vorteil, wenn die Ereignisse nach ihrer Entfernung zur jeweiligen Arbeitsstelle gewichtet werden. So wird üblicherweise die meiste Verschmutzung durch den Spinnbetrieb an der jeweiligen Arbeitsstelle selbst verursacht. Aber auch der Spinnbetrieb an den benachbarten Arbeitsstellen verursacht eine gewisse, aber mit zunehmendem Abstand geringere, Verschmutzung einer Arbeitsstelle. Je größer also die Entfernung der Arbeitsstelle, an der ein Ereignis auftritt, zur beobachteten Arbeitsstelle ist, desto kleiner wird der Gewichtungsfaktor gewählt. Üblicherweise wird es ausreichen, die Ereignisse von ein paar wenigen benachbarten Arbeitsstellen zu berücksichtigen.It is also advantageous if the events are weighted according to their distance to the respective job. Thus, most of the pollution is usually caused by the spinning operation at the work site itself. But the spinning operation at the neighboring jobs causes a certain, but with increasing distance lower, pollution of a job. Thus, the greater the distance of the work site at which an event occurs, the observed work site, the smaller the weighting factor is chosen. Usually it will be sufficient to consider the events of a few neighboring jobs.
Vorteilhaft ist es auch, wenn die Abhängigkeit eine vorbestimmte Abfolge von Ereignissen ist. Wird beispielsweise zwischen zwei Spulenwechseln eine bestimmte Anzahl von Ansetzvorgängen überschritten, so ist davon auszugehen, dass ein Fehler vorliegt. Dieser Fehler könnte von einer zu stark verschmutzten Arbeitsstelle kommen, könnte aber auch andere Ursachen haben. Das Stellen einer Reinigungsanforderung nach einer bestimmten Anzahl von Ansetzvorgängen hintereinander dient also dazu, eine mögliche Verschmutzung als Fehlerursache zu beheben. Sollten nach erfolgter Reinigung weiterhin viele Ansetzvorgänge hintereinander ausgeführt werden, dann ist die Ursache des Fehlers wohl eine andere. In dem Fall muss eine Wartungsvorrichtung die Arbeitsstelle warten oder Bedienpersonal die Ursache der Häufung von Ansetzvorgängen untersuchen.It is also advantageous if the dependency is a predetermined sequence of events. If, for example, a certain number of piecing processes is exceeded between two bobbin changes, then it can be assumed that an error has occurred. This error could be from too dirty Work, but could have other causes as well. The provision of a cleaning request after a certain number of piecing operations in succession thus serves to remedy a possible contamination as the cause of the error. If, after cleaning, many attachments continue to be performed consecutively, then the cause of the error is probably a different one. In that case, a maintenance device must wait for the job or operators must investigate the cause of the accumulation of attachments.
Wenn die letzte Reinigung einer Arbeitsstelle schon eine längere Zeit zurückliegt, dann kann diese Arbeitsstelle insbesondere auch durch in der Umgebungsluft enthaltenen Staub bzw. Fasern verschmutzen. Ist seit der letzten Reinigung der Arbeitsstelle also schon eine vorbestimmte Zeit vergangen, dann ist es von Vorteil, wenn eine Reinigungsanforderung für diese Arbeitsstelle gestellt wird, um sicherzustellen, dass die entsprechenden Arbeitsstellen zu keiner Zeit übermäßig verunreinigt werden.If the last cleaning of a job is already a long time ago, then this job can also be contaminated by dust or fibers contained in the ambient air. If a predetermined time has already elapsed since the last cleaning of the workstation, it is advantageous if a cleaning request for this workstation is made to ensure that the corresponding workstations are never excessively contaminated at any time.
Vorteilhafterweise wird eine Reinigungsanforderung nur für laufende Arbeitsstellen gestellt. Wenn eine Arbeitsstelle eine längere Zeit nicht läuft, könnte es durch Ereignisse an benachbarten Arbeitsstellen passieren, dass dennoch eine Reinigungsanforderung gestellt wird. Es lohnt sich jedoch nur, eine Reinigungsanforderung zu stellen, wenn die Arbeitsstelle bald darauf wieder läuft. Da dies bei Arbeitsstellen, die längere Zeit nicht laufen, nicht vorherzusehen ist, ist es effizienter, wenn nicht laufende Arbeitsstellen keine Reinigungsanforderungen stellen.Advantageously, a cleaning request is made only for current jobs. If a job does not run for an extended period of time, events at neighboring jobs could still cause a clean request. However, it is only worthwhile to ask for a cleaning request if the workstation soon resumes. Since this can not be foreseen for jobs that are not running for a long time, it is more efficient when non-current jobs do not require cleaning.
Liegt andererseits eine nicht laufende Arbeitsstelle auf dem Weg einer Reinigungsvorrichtung, dann ist es günstig, wenn sie in Abhängigkeit von den seit dem letzten Reinigungsvorgang angefallenen Ereignissen auch gereinigt wird, so dass eine übermäßige Verschmutzung dieser Arbeitsstelle vermieden wird.On the other hand, if a non-working job on the way a cleaning device, then it is advantageous if it is also cleaned depending on the incurred since the last cleaning events, so that excessive pollution of this job is avoided.
Vorteilhaft ist es, wenn die fahrbare Reinigungsvorrichtung als separates Reinigungsaggregat betrieben wird. Dann kann die Reinigungsvorrichtung weitgehend unabhängig von anderen Wartungsvorrichtungen entlang der Textilmaschine und damit zu den einzelnen Arbeitsstellen verfahren werden und muss die Abarbeitung der Reinigungsanforderungen nicht mit anderen Wartungsanforderungen koordinieren.It is advantageous if the mobile cleaning device is operated as a separate cleaning unit. Then, the cleaning device can be moved largely independently of other maintenance devices along the textile machine and thus to the individual jobs and does not coordinate the execution of the cleaning requirements with other maintenance requirements.
Es kann aber auch von Vorteil sein, wenn die Reinigungsvorrichtung als Teil einer größeren verfahrbaren Wartungsvorrichtung betrieben wird. So benötigt die Reinigungsvorrichtung keinen separaten Antrieb und es muss nicht auf mögliche Kollisionen zwischen der Reinigungsvorrichtung und der größeren Wartungsvorrichtung geachtet werden (wobei die Wartungsvorrichtung beispielsweise als Serviceroboter ausgebildet ist, der die oben genannten Ansetzvorgänge durchführt).But it may also be advantageous if the cleaning device is operated as part of a larger movable maintenance device. Thus, the cleaning device does not require a separate drive and care must be taken not to possible collisions between the cleaning device and the larger maintenance device (the maintenance device is formed, for example, as a service robot, which performs the aforementioned Ansetzvorgänge).
Bei Textilmaschinen mit einer großen Zahl an Arbeitsstellen ist mehr als eine Reinigungsvorrichtung nötig, um alle Reinigungsanforderungen zu bedienen. Dann ist es von Vorteil, wenn ein Überschneidungsbereich vorgesehen ist, der von mindestens zwei Reinigungsvorrichtungen gereinigt werden kann. Durch ein geschicktes Verteilen der im Überschneidungsbereich anfallenden Reinigungsanforderungen kann nämlich die Effizienz der Reinigungsvorrichtungen erhöht werden. Vorzugsweise hält sich dabei höchstens eine Reinigungsvorrichtung zu einem gegebenen Zeitpunkt im Überschneidungsbereich auf. Dies ist eine einfache, aber effektive Methode, Kollisionen zwischen den Reinigungsvorrichtungen zu vermeiden.For textile machines with a large number of jobs, more than one cleaning device is needed to serve all cleaning requirements. Then it is advantageous if an overlapping area is provided which can be cleaned by at least two cleaning devices. By cleverly distributing the cleaning requirements arising in the overlapping area, namely the efficiency of the cleaning devices can be increased. Preferably, at most one cleaning device at a given point in time remains in the overlapping area. This is a simple but effective way to avoid collisions between the cleaning devices.
Wenn die Reinigungsanforderung für eine Arbeitsstelle im Überschneidungsbereich gestellt wird, ist es vorteilhaft, wenn der Reinigungsvorgang von derjenigen Reinigungsvorrichtung durchgeführt wird, die eine geringere Arbeitsauslastung aufweist. So wird eine Anpassung der Arbeitsauslastungen erreicht und die Effizienz der Reinigungsvorrichtungen gesteigert.When the cleaning request for a work site is placed in the overlapping area, it is advantageous if the cleaning operation is performed by the cleaning device having a lower workload. Thus, an adaptation of the workloads is achieved and increases the efficiency of the cleaning devices.
Wenn die Reinigungsanforderung für eine Arbeitsstelle im Überschneidungsbereich gestellt wird, kann es jedoch auch von Vorteil sein, wenn der Reinigungsvorgang von derjenigen Reinigungsvorrichtung durchgeführt wird, die näher an der Arbeitsstelle ist, für die die Reinigungsanforderung gestellt wurde. Mit dieser Strategie werden unnötig weite Fahrwege der Reinigungsvorrichtungen vermieden und die Reinigungen können zeitnäher durchgeführt werden.However, if the cleaning request for a job is placed in the overlap area, it may also be advantageous if the cleaning operation is performed by the cleaning device that is closer to the work site for which the cleaning request was made. With this strategy unnecessarily long travel distances of the cleaning devices are avoided and the cleaning can be carried out more quickly.
Ferner wird eine Textilmaschine mit einer Mehrzahl von gleichen Arbeitsstellen vorgeschlagen. Die Textilmaschine weist außerdem eine fahrbare Reinigungsvorrichtung und eine Steuereinrichtung auf. Dabei ist die Steuereinrichtung dazu ausgebildet, Reinigungsanforderungen für Arbeitsstellen zu stellen und die Reinigungsvorrichtung dazu ausgebildet, eine Arbeitsstelle, für die eine Reinigungsanforderung gestellt wurde, anzufahren und zu reinigen.Furthermore, a textile machine with a plurality of identical jobs is proposed. The textile machine also has a mobile cleaning device and a control device. In this case, the control device is designed to provide cleaning requirements for jobs and the cleaning device is adapted to approach and clean a job for which a cleaning request has been made.
Erfindungsgemäß ist die Steuereinrichtung derart ausgebildet, dass sie die Textilmaschine gemäß den bisher beschriebenen Aspekten reinigt. Die Steuereinrichtung stellt also Reinigungsanforderungen in Abhängigkeit von an den jeweiligen Arbeitsstellen seit dem letzten Reinigungsvorgang angefallenen Ereignissen. Diese Ereignisse sind dabei ein Indiz für die seit dem letzten Reinigungsvorgang angefallene Verschmutzung der Arbeitsstelle. Die Steuereinrichtung ist also dazu ausgebildet, beim Stellen der Reinigungsanforderungen die unterschiedliche Verschmutzung der Arbeitsstellen zu berücksichtigen.According to the invention, the control device is designed such that it cleans the textile machine according to the aspects described so far. The control device thus provides cleaning requirements as a function of events occurring at the respective work stations since the last cleaning process. These events are an indication of the pollution of the workplace since the last cleaning process. The control device is thus designed to take into account the different contamination of the jobs when setting the cleaning requirements.
Von Vorteil ist es dabei, wenn die fahrbare Reinigungsvorrichtung als separates Reinigungsaggregat ausgebildet ist. Dann kann die Reinigungsvorrichtung weitgehend unabhängig von anderen Wartungsvorrichtungen entlang der Textilmaschine verfahren werden und muss die Abarbeitung der Reinigungsanforderungen nicht mit anderen Wartungsanforderungen koordinieren.It is advantageous if the mobile cleaning device is designed as a separate cleaning unit. Then the cleaning device can be moved largely independently of other maintenance devices along the textile machine and does not have to coordinate the execution of the cleaning requirements with other maintenance requirements.
Es kann aber auch von Vorteil sein, wenn die Reinigungsvorrichtung als Teil einer größeren fahrbaren Wartungsvorrichtung ausgebildet ist. So wird ein separater Antrieb für die Reinigungsvorrichtung gespart und es muss nicht auf mögliche Kollisionen zwischen der Reinigungsvorrichtung und der größeren Wartungsvorrichtung geachtet werden.But it may also be advantageous if the cleaning device is designed as part of a larger mobile maintenance device. Thus, a separate drive for the cleaning device is saved and there is no need to pay attention to possible collisions between the cleaning device and the larger maintenance device.
Weitere Vorteile der Erfindung sind in den nachfolgenden Ausführungsbeispielen beschrieben. Es zeigt:

Die Arbeitsstelle 2 weist ein Spinnaggregat 3 auf, das ein aus einer Kanne 4 kommendes Faserband 5 zu einem Faden 6 verspinnt. Der Faden 6 wird dann von einem Abzugswalzenpaar 7 übernommen und mittels eines Changierelements 8 auf einer Spule 9 aufgewickelt.The
Ereignisse wie ein Wechsel der Kanne 4, ein Wechsel der Spule 9 oder ein Ansetzen des Fadens 6 werden von der Arbeitsstelle 2 an eine Steuereinrichtung der Textilmaschine übermittelt. Ist ein vorbestimmter Schwellenwert an gewichteten Ereignissen für die Arbeitsstelle 2 erreicht oder überschritten, fordert die Steuereinrichtung die Reinigung der Arbeitsstelle 2 durch die Reinigungsvorrichtung 1 an.Events such as a change of the
Die Reinigungsvorrichtung 1 fährt dann entlang von Schienen 10 bis zur Arbeitsstelle 2, wo sie sich mittels eines der Arbeitsstelle zugeordneten Positionierelements 11 exakt positioniert. Die Reinigung selbst wird in diesem Ausführungsbeispiel von einem Saugrüssel 12 durchgeführt. Der Saugrüssel 12 ist dabei über mehrere Arme 13, 14, 15 mit dem Fahrgestell 16 der Reinigungsvorrichtung 1 verbunden. Der Saugrüssel 12 und die Arme 13, 14 sind um horizontale Achsen 17, 18, 19 und der Saugrüssel zusätzlich um die vertikale Achse 20 schwenkbar. So kann der Saugrüssel 12 zu den abzusaugenden Objekten der Arbeitsstelle 2 bewegt werden.The
Das hier beschriebene Verfahren beschränkt sich allerdings nicht auf eine Reinigung durch Absaugen von Verschmutzungen; vielmehr sind auch andere Reinigungsmethoden, beispielsweise mit Druckluft oder mit mechanischen Reinigungselementen, denkbar.However, the method described here is not limited to a cleaning by suction of dirt; Rather, other cleaning methods, for example with compressed air or with mechanical cleaning elements, conceivable.
Die Arbeitsstellen 2 sind einem von drei Bereichen zugeordnet: einem exklusiven Bereich EB1, der sich auf einer Maschinenseite der Textilmaschine 21 befindet, einem exklusiven Bereich EB2, der sich auf der anderen Maschinenseite befindet, und einem Überschneidungsbereich Ü.The
Die Arbeitsstellen 2 senden Informationen über Ereignisse wie Kannenwechsel, Spulenwechsel und/oder Ansetzvorgänge an eine am Maschinenende 22 angeordnete Steuereinrichtung 23. Diese Ereignisse werden von der Steuereinrichtung 23 mit einem Gewichtungsfaktor versehen. Dabei ist der Gewichtungsfaktor umso größer, je größer die dem Ereignis zugeordnete Verschmutzung ist. Für jede Arbeitsstelle 2 wird eine Summe der gewichteten Ereignisse gebildet. Dabei werden auch Ereignisse, die an benachbarten Arbeitsstellen 2 angefallen sind, gezählt, allerdings werden diese Ereignisse mit einem weiteren Gewichtungsfaktor versehen, der umso kleiner ist, je größer der Abstand vom Ereignis zur Arbeitsstelle 2 ist.The
Ist ein Schwellenwert an gewichteten Ereignissen für eine Arbeitsstelle 2 überschritten, so wird eine Reinigungsanforderung für diese Arbeitsstelle 2 gestellt. Befindet sich die Arbeitsstelle 2 im exklusiven Bereich EB1, der der in
Auf dem Weg der Reinigungsvorrichtung 1 zur Arbeitsstelle 2, für die die Reinigungsanforderung gestellt wurde, werden außerdem alle Arbeitsstellen 2 gereinigt, deren gewichtete Ereignissumme einen bestimmten Schwellenwert überschreitet.In addition, on the way of the
