Description

Die Erfindung betrifft eine Textilmaschine mit einer Vielzahl gleichartiger Spulen, insbesondere Kreuzspulen herstellender Arbeitsstellen, die jeweils einen Fadenspeicher und mindestens einen entlang der Arbeitsstellen verfahrbaren Servicewagen aufweisen.The invention relates to a textile machine with a large number of similar bobbins, in particular work stations producing cross-wound bobbins, each of which has a thread store and at least one service trolley that can be moved along the work stations.

Textilmaschinen der eingangs genannten Art sind in vielfältigen Ausgestaltungen aus dem Stand der Technik bekannt. Üblicherweise weisen diese eine Vielzahl benachbart zueinander angeordneter Arbeitsstellen auf, an denen ein Faden auf eine Spule, in der Regel eine Kreuzspule aufgewickelt wird. Dies können Spul- oder Spinnmaschinen sein. An einer Spinnmaschine wird beispielsweise aus einem vorgelegten Faserverband ein Faden hergestellt, der nach Verlassen der Spinneinheit - in Richtung des Fadenlaufs betrachtet - nacheinander, d. h. in Transportrichtung des Fadens, beispielsweise die hintereinanderliegend angeordnete Abzugseinrichtung und den Fadenspeicher, passiert, bevor der Faden abschließend mittels einer Fadenaufspulvorrichtung auf eine Kreuzspule aufgewickelt wird. Eine unmittelbar aufeinanderfolgende Anordnung von Fadenaufspulvorrichtung und Fadenspeicher ist dabei nicht zwangsläufig erforderlich, sondern es können auch weitere Komponenten der Arbeitsstelle zwischengeschaltet sein. Zu bekannten Spinnmaschinen zählen dabei insbesondere Luftspinn- und Rotorspinnmaschinen, die ebenfalls grundsätzlich aus dem Stand der Technik bekannt sind.Textile machines of the type mentioned at the beginning are known in various configurations from the prior art. These usually have a large number of work stations arranged adjacent to one another, at which a thread is wound onto a bobbin, usually a cross-wound bobbin. These can be winding or spinning machines. On a spinning machine, for example, a thread is produced from a fiber structure placed in front of it, which after leaving the spinning unit - viewed in the direction of the thread path - one after the other, i. H. in the transport direction of the thread, for example the take-off device arranged one behind the other and the thread store, passes before the thread is finally wound onto a cross-wound bobbin by means of a thread winding device. An arrangement of thread winding device and thread storage device in direct succession is not absolutely necessary, but further components of the work station can also be interposed. Known spinning machines include in particular air-jet spinning and rotor spinning machines, which are also basically known from the prior art.

An den Textilmaschinen dienen die jeweils an den Arbeitsstellen vorhandenen Fadenspeicher zum Zwischenspeichern eines Fadenabschnitts, wobei unter dem Begriff "Zwischenspeichern" die Anordnung einer Fadenschlaufe während des Transports, beispielsweise ausgehend von einer Spinneinheit zur Aufspulvorrichtung innerhalb des Fadenspeichers verstanden wird, so dass Schwankungen in der Aufspulgeschwindigkeit der Aufspulvorrichtung und/oder einer Abzugseinrichtung sowie Schwankungen in der Liefergeschwindigkeit der Spinneinheit ausgeglichen werden können, wobei es hierbei zu einem schwankenden Füllstand des Fadenspeichers kommt.On the textile machines, the thread stores present at the work stations are used to temporarily store a thread section, the term "temporary storage" being understood to mean the arrangement of a thread loop during transport, for example starting from a spinning unit to the winding device within the thread store, so that fluctuations in the winding speed the winding device and / or a take-off device as well as fluctuations in the delivery speed of the spinning unit can be compensated for, with a fluctuating fill level of the yarn store.

Gegenüber Textilmaschinen mit Arbeitsstellen, welche keinen Fadenspeicher besitzen, treten bei Fadenspeicher aufweisenden Arbeitsstellen neue Fehlerzustände auf, die mit herkömmlichen Fehlerbehebungseinrichtungen, welche beispielsweise an den jeweiligen Arbeitsstellen angeordnet sind oder durch den entlang der Arbeitsstellen verfahrbaren und an den fehlerbehafteten Arbeitsstellen positionierbaren Servicewagen bereitgestellt werden, nicht behoben werden können. Zu den neuartigen Fehlerzuständen zählt beispielsweise das Reißen des Fadens innerhalb des Fadenspeichers, was es in Ermangelung einer geeigneten Fehlerbehebungseinrichtung an dem Servicewagen oder der Arbeitsstelle erforderlich macht, die Fehlerbehebung durch einen manuellen Eingriff des Bedienpersonals durchzuführen.Compared to textile machines with workplaces that do not have a thread store, new error states occur in workplaces with thread stores, which can be caused by conventional troubleshooting devices, which are arranged, for example, at the respective workplaces or by means of which can be moved along the workplaces the faulty workplaces are provided with positionable service trolleys, cannot be remedied. The novel error states include, for example, the tearing of the thread within the thread store, which, in the absence of a suitable error correction device on the service vehicle or the work station, makes it necessary to carry out the error correction by manual intervention by the operating personnel.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Textilmaschine mit einer Vielzahl Fadenspeicher aufweisenden Arbeitsstellen bereitzustellen, bei der in Verbindung mit dem Fadenspeicher auftretende Fehlerzustände automatisiert behoben werden können.Proceeding from this, the invention is based on the object of providing a textile machine with a plurality of workstations having a plurality of thread stores, in which error states occurring in connection with the thread store can be remedied in an automated manner.

Die Erfindung löst die Aufgabe durch eine Textilmaschine mit den Merkmalen des Anspruchs 1 sowie durch einen Servicewagen mit den Merkmalen des Anspruchs 8. Vorteilhafte Weiterbildungen der Textilmaschine sind in den abhängigen Ansprüchen 2 bis 7 angegeben.The invention achieves the object by a textile machine with the features of claim 1 and by a service trolley with the features of claim 8. Advantageous further developments of the textile machine are given in the dependent claims 2 to 7.

Kennzeichnend für die erfindungsgemäße Textilmaschine ist, dass der Servicewagen ein Entstörungsmittel zur automatischen Behebung von im Fadenspeicher auftretenden und/oder dem Fadenspeicher zuzuordnenden Fehlerzuständen aufweist.It is characteristic of the textile machine according to the invention that the service trolley has an interference suppression means for the automatic elimination of error states occurring in the thread store and / or to be assigned to the thread store.

Bei der erfindungsgemäßen Textilmaschine ist der entlang der einzelnen Arbeitsstellen der Textilmaschine verfahrbare und an den einzelnen Arbeitsstellen positionierbare Servicewagen dazu ausgebildet, solche Fehler zu beheben, welche in Verbindung mit der Verwendung des Fadenspeichers an den Arbeitsstellen auftreten. Zu den spezifischen Störfällen in Verbindung mit dem Fadenspeicher zählt insbesondere ein Fadenriss innerhalb des Fadenspeichers, wobei durch die Entstörungsmittel am Servicewagen der erfindungsgemäßen Textilmaschine in diesem Fall eine Fehlerbehebung stattfinden kann, in deren Zuge eine Wiederherstellung der Verbindung des Fadens, ausgehend beispielsweise von der Spinnstelle bis zur Auflaufspule, bevorzugt der Kreuzspule, hergestellt wird.In the textile machine according to the invention, the service trolley, which can be moved along the individual workstations of the textile machine and positioned at the individual workstations, is designed to correct errors that occur in connection with the use of the thread store at the workstations. The specific malfunctions in connection with the thread store include, in particular, a thread break within the thread store, in which case the interference suppression means on the service trolley of the textile machine according to the invention can be used to remedy the fault, in the course of which the connection of the thread is re-established, for example from the spinning station to to the package, preferably the cross-wound bobbin.

Die erfindungsgemäße Textilmaschine gewährleistet im besonderen Maße, dass Fehlerzustände in Verbindung mit dem Fadenspeicher automatisiert behoben werden können, so dass auf einen manuellen Eingriff durch das Bedienpersonal verzichtet werden kann. In Folge der Senkung der manuellen Eingriffe zur Fehlerkorrektur können die Stillstandzeiten der Arbeitsstellen erheblich reduziert werden. Aufgrund der nur in einem geringen Umfang auftretenden Fehlerzuständen in Verbindung mit dem Fadenspeicher stellt die Anordnung der entsprechenden Entstörungsmittel an einem Servicewagen eine besonders wirtschaftliche Lösung gegenüber der Anordnung entsprechender Entstörungsmittel an den einzelnen Arbeitsstellen dar. Der Servicewagen kann im Bedarfsfall kurzfristig die jeweilige Arbeitsstelle anfahren und dort den in Verbindung mit dem Fadenspeicher auftretenden Fehler zuverlässig beheben.The textile machine according to the invention ensures to a particular degree that error states in connection with the thread store can be automatically corrected, so that manual intervention by the operating personnel can be dispensed with. As a result of the reduction in manual interventions to correct errors, the downtimes at the workplaces can be reduced considerably. Due to the error states occurring only to a small extent in connection with the thread store, the arrangement of the Corresponding interference suppression means on a service trolley represent a particularly economical solution to the arrangement of corresponding interference suppression means at the individual workstations.

Erfindungsgemäß ist der Servicewagen zur Fehlerbehebung solcher Störungen ausgebildet, die aus der Verwendung der Fadenspeicher an den Arbeitsstellen resultieren. Darüber hinaus kann der Servicewagen auch zur Durchführung weiterer Arbeiten ausgebildet sein, wie beispielsweise die Behebung weiterer Störungen, die nicht im Zusammenhang mit dem Fadenspeicher stehen oder das Auswechseln der Kreuzspulen.According to the invention, the service trolley is designed for troubleshooting such malfunctions that result from the use of the thread store at the work stations. In addition, the service trolley can also be designed to carry out further work, such as, for example, the elimination of further malfunctions that are not related to the thread store or the exchange of the cross-wound bobbins.

Die Ausgestaltung der Entstörungsmittel zur Fehlerbehebung fadenspeicherspezifischer Störungszustände ist grundsätzlich frei wählbar. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass die Entstörungsmittel ein Reinigungsaggregat zur Entfernung von Fadenresten aus dem Fadenspeicher aufweisen. Die Verwendung eines Reinigungsaggregats gewährleistet im besonderen Maße, dass Fadenreste oder Rückstande in Folge des Fadenlaufs durch den Fadenspeicher aus dem Fadenspeicher entfernt werden, wo diese im Betrieb zu Störungen führen können. Der Einsatz des Reinigungsaggregats erfolgt dabei im Rahmen der Behebung einer fadenspeicherspezifischen Störung, wobei das Reinigungsaggregat beispielsweise pneumatisch wirkend ausgebildet sein kann und mittels Über- oder Unterdruck eine Luftströmung innerhalb des Fadenspeichers erzeugt wird, durch die Verunreinigungen abgeführt werden.The design of the interference suppression means for troubleshooting thread storage-specific fault conditions can in principle be freely selected. According to a particularly advantageous embodiment of the invention, however, it is provided that the interference suppression means have a cleaning unit for removing thread remnants from the thread store. The use of a cleaning unit ensures in particular that thread remnants or residues as a result of the thread run through the thread store are removed from the thread store, where they can lead to malfunctions during operation. The cleaning unit is used in the context of eliminating a thread storage-specific malfunction, whereby the cleaning unit can be designed to act pneumatically, for example, and an air flow is generated within the thread storage by means of overpressure or underpressure, through which impurities are removed.

Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass die Entstörungsmittel eine optische Inspektionseinrichtung zur Überprüfung des Fadenspeichers aufweisen. Die optische Inspektionseinrichtung kann dazu ausgebildet sein, den an der Arbeitsstelle auftretenden Fehler zu identifizieren, so dass geeignete Maßnahmen zur Fehlerbehebung durchgeführt werden können. Alternativ oder ergänzend kann die optische Inspektionseinrichtung auch zur Überwachung der Fehlerbehebung und/oder zur Kontrolle der durchgeführten Fehlerbehebungen verwendet werden, wobei beispielsweise mittels der optischen Inspektionseinrichtung das Innere des Fadenspeichers auf verbleibende Rückstände überprüft und/oder der Fadenlauf innerhalb des Fadenspeichers nach der Fehlerbehebung kontrolliert wird.According to a further embodiment of the invention it is provided that the interference suppression means have an optical inspection device for checking the thread store. The optical inspection device can be designed to identify the error occurring at the work site, so that suitable measures for eliminating the error can be carried out. As an alternative or in addition, the optical inspection device can also be used to monitor the elimination of errors and / or to check the error corrections carried out, with the inside of the thread store being checked for remaining residues by means of the optical inspection device, for example, and / or the thread path within the thread store being checked after the error has been eliminated .

Im Rahmen der Fehlerbehebung ist es in der Regel erforderlich, einen gerissenen Faden wieder zu verbinden, damit der Spulvorgang an den Arbeitsstellen der Textilmaschine fortgeführt werden kann. Zur Herstellung der Fadenverbindung können an den einzelnen Arbeitsstellen beispielsweise von Spulmaschinen geeignete Verbindungseinrichtungen angeordnet sein. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass der Servicewagen eine Fadenverbindungseinrichtung aufweist. Die Anordnung einer Fadenverbindungseinrichtung an dem Servicewagen stellt eine besonders wirtschaftliche Lösung zur Fadenverbindung dar. Die Fadenverbindungseinrichtung kann dabei auch ergänzend zu den an den Arbeitsstellen angeordneten Fadenverbindungseinrichtungen vorhanden sein, wobei die an dem Servicewagen ausgebildete Fadenverbindungseinrichtung insbesondere zur Wiederherstellung einer Fadenverbindung nach Auftreten eines fadenspeicherspezifischen Problems ausgebildet ist.As part of troubleshooting, it is usually necessary to reconnect a broken thread so that the winding process can be continued at the workstations of the textile machine. To produce the thread connection, suitable connection devices can be arranged at the individual work stations, for example from winding machines. According to a particularly advantageous embodiment of the invention, however, it is provided that the service trolley has a thread connecting device. The arrangement of a thread connection device on the service trolley represents a particularly economical solution for thread connection. The thread connection device can also be present in addition to the thread connection devices arranged at the work stations, the thread connection device formed on the service trolley being designed in particular to restore a thread connection after a thread storage-specific problem has occurred is.

Die Ausgestaltung der Fadenverbindungseinrichtung ist dabei grundsätzlich frei wählbar. Nach einer besonders vorteilhaften Ausgestaltung ist jedoch vorgesehen, dass die Fadenverbindungseinrichtung eine Fadensuchdüse und Manipulationsmittel zur Positionierung des freien von der Kreuzspule abgezogenen Fadenendes im Bereich eines Fadenverbinders, insbesondere einer Spleiß- und/oder Knoteinheit aufweist. Die entsprechende Ausgestaltung der Fadenverbindungseinrichtung macht den Servicewagen unabhängig von den entsprechenden Aggregaten an den Arbeitsstellen. Die gemäß dieser Weiterbildung der Erfindung ausgebildete Fadenverbindungseinrichtung ermöglicht es vollständig, das zur Verbindung vorgesehene Fadenende von der Kreuzspule abzunehmen und nach Vorbereitung dem Fadenverbinder zuzuführen. Eine entsprechend ausgebildete Fadenverbindungseinrichtung gewährleistet aufgrund der optimalen Ausrichtung der einzelnen Aggregate zueinander eine besonders zuverlässige Funktionsweise, wodurch Stillstandzeiten in ergänzender Weise reduziert werden können.The design of the thread connecting device can in principle be freely selected. According to a particularly advantageous embodiment, however, it is provided that the thread connecting device has a thread search nozzle and manipulation means for positioning the free thread end withdrawn from the cheese in the area of a thread connector, in particular a splice and / or knot unit. The corresponding design of the thread connecting device makes the service trolley independent of the corresponding units at the work stations. The thread connecting device designed according to this development of the invention makes it possible completely to remove the thread end provided for the connection from the cheese and, after preparation, to feed it to the thread connector. A correspondingly designed thread connecting device ensures a particularly reliable mode of operation due to the optimal alignment of the individual units with respect to one another, whereby downtimes can be reduced in a complementary manner.

Gemäß einer weiteren Ausgestaltung der Erfindung kann die Fadenverbindungseinrichtung auch zur Anordnung des freien Fadenendes an einer Anspinnstelle der Arbeitsstelle ausgebildet sein. Bei einer entsprechenden Ausgestaltung des Servicewagens kann somit über diesen ohne Rückgriff auf Aggregate an der Arbeitsstelle in zuverlässiger Weise eine erneute Fadenverbindung hergestellt werden, wobei diese an der Anspinnstelle der Arbeitsstelle hergestellt wird, an der das von der Kreuzspule kommende freie Fadenende mit dem aus der Spinneinrichtung zugeführten Faden verbunden wird.According to a further embodiment of the invention, the thread connecting device can also be designed for arranging the free thread end at a piecing point of the work station. With a corresponding design of the service car, a new thread connection can be reliably established via this without resorting to units at the work site, this being made at the piecing point of the work site at which the free thread end coming from the cross-wound bobbin with that from the Spinning device fed thread is connected.

Nach einer weiteren Ausgestaltung der Erfindung ist ferner vorgesehen, dass der Servicewagen Fadeninspektionsmittel, insbesondere optisch wirkende Fadeninspektionsmittel aufweist. Die Fadeninspektionsmittel ermöglichen es, insbesondere nach einer Wiederherstellung der Fadenverbindung, diese zu Überprüfen und nach positiver Prüfung den Betrieb an der Arbeitsstelle freizugeben. Fehlerhafte Verbindungen können über das Fadeninspektionsmittel erkannt und über geeignete Maßnahmen behoben werden, so dass erneute Störungen aufgrund der fehlerhaften Verbindung vermieden werden.According to a further embodiment of the invention it is further provided that the service trolley has thread inspection means, in particular optical thread inspection means. The thread inspection means make it possible, especially after the thread connection has been re-established, to check it and, after a positive check, to enable operation at the work site. Faulty connections can be recognized via the thread inspection device and corrected using suitable measures, so that renewed malfunctions due to the faulty connection are avoided.

Die Erfindung löst die Aufgabe ferner durch einen Servicewagen mit den Merkmalen des Anspruchs 8, welcher dadurch gekennzeichnet ist, dass dieser ein Entstörungsmittel zur automatischen Behebung von im Fadenspeicher auftretenden und/oder dem Fadenspeicher zuzuordnenden Fehlerzuständen ausgebildet ist. Der Servicewagen kann dabei gemäß einer oder mehrerer vorstehend zur Textilmaschine dargestellten Weiterbildungen des Servicewagens ausgebildet sein, wodurch die Funktionalität des Servicewagens für die Textilmaschine in ergänzender Weise gesteigert wird.The invention also solves the problem by a service trolley with the features of claim 8, which is characterized in that it is designed as an interference suppression means for automatic elimination of error states occurring in the thread store and / or to be assigned to the thread store. The service trolley can be designed according to one or more developments of the service trolley described above for the textile machine, whereby the functionality of the service trolley for the textile machine is increased in a complementary manner.

Im Falle eines beispielsweise innerhalb des Fadenspeichers 17 stattgefundenen Fadenbruchs wird der Servicewagen 10 zu der betreffenden Arbeitsstelle 2 verfahren, positioniert sich dort und beginnt unter Verwendung der hier nicht dargestellten Entstörungsmittel mit der Fehlerbehebung. Im Falle eines Fadenbruchs innerhalb des Fadenspeichers 17 kann der Servicewagen 10 über eine zu den Störungsmittel zählende Fadensuchdüse das gerissene, auf der Umfangsoberfläche der Kreuzspule 9 liegende Fadenende auffinden. Nach Reinigung der Spinnvorrichtung 5 wird dieses Fadenende, wie üblich, durch bekannte zu den Entstörungsmitteln zählende Handhabungseinrichtungen, nach einer entsprechenden Vorbereitung, in den Bereich der Spinnvorrichtung 5 zurückbefördert und dort für den eigentlichen Anspinnprozess bereitgehalten. Gleichzeitig wird über den Antrieb der Kreuzspulen 9 eine definierte Fadenlänge abgewickelt und in dem Fadenspeicher 17 zwischengespeichert.In the event of a malfunction at a work station 2 in the area of the thread store 17, the service trolley 10 is positioned along the textile machine 1 at the work station 2 exhibiting the malfunction. In the event of a thread breakage occurring, for example, within the thread store 17, the service trolley 10 is moved to the relevant work station 2, positions itself there and starts troubleshooting using the interference suppression means not shown here. In the event of a thread break within the thread store 17, the service trolley 10 can find the torn thread end lying on the circumferential surface of the cheese 9 via a thread search nozzle, which is one of the interference means. After cleaning the spinning device 5, this thread end is, as usual, conveyed back to the area of the spinning device 5 by known handling devices belonging to the interference suppression means and held there for the actual piecing process. At the same time, a defined length of thread is unwound via the drive of the cross-wound bobbins 9 and is temporarily stored in the thread store 17.
