Description

Die Erfindung betrifft eine Vielstellentextilmaschine mit einem entlang der Arbeitsstellen verfahrbaren Wanderaggregat, wobei zur Reinigung der Vielstellentextilmaschine von Flusen und Staub sowohl an dem Wanderaggregat als auch an den Arbeitsstellen Öffnungen zur Beaufschlagung mit Saug- oder Druckluft vorhanden sind.The invention relates to a multi-purpose textile machine with a walkable along the work stations hiking aggregate, which are available for cleaning the multi-purpose textile machine of lint and dust on both the hiking aggregate and at the work openings for admission with suction or compressed air.

Bei Spinn- und Spulprozessen fallen erhebliche Mengen von Staubteilchen, Flusen sowie Avivage- und Schmutzpartikeln an, die in der Luft schweben und von denen sich eine Teilmenge auf den Oberflächen der Bauteile der Spinn- und Spulmaschinen ablagert. Die Staub- und Schmutzentwicklung ist von dem zu verarbeitenden Material und den gewählten Produktionsparametem, wie beispielsweise der Wickelgeschwindigkeit oder der Paraffinierung, abhängig. Zusätzlich wird das Freisetzen derartiger Partikel von der Reibung begünstigt, der der laufende Faden an einigen Stellen im Fadenlauf, zum Beispiel an Fadenführern, ausgesetzt ist. Darüber hinaus erfolgt durch den Betrieb benachbarter Textilmaschinen eine zusätzliche Kontaminierung.Spinning and winding processes involve considerable quantities of dust particles, lint, as well as softening and dirt particles, which float in the air and from which a partial quantity deposits on the surfaces of the components of the spinning and winding machines. The development of dust and dirt depends on the material to be processed and the production parameters chosen, such as the speed of winding or the waxing. In addition, the release of such particles from the friction is favored, the running thread is exposed at some points in the threadline, for example on thread guides. In addition, by the operation of adjacent textile machines, an additional contamination.

Die Verschmutzung kann im Falle einer Spulmaschine zum Beispiel den Fadenspanner, den Messkopf des Fadenreinigers oder die Paraffiniereinrichtung betreffen. Diese Verschmutzungen können zu Funktionsproblemen in der Vielstellentextilmaschine und zu Qualitätsproblemen der herzustellenden Kreuzspule führen. Wenn sich beispielsweise Verschmutzungen zwischen den Tellern eines Tellerspanners befinden, kann die Fadenspannung nicht mehr korrekt eingestellt werden. Eine Verschmutzung des Reinigermesskopfes kann zu einer falschen Kalibrierung oder zu falschen Messwerten des Reinigers führen. Damit werden Dick-, Dünnstellen oder Fremdfasem signalisiert wo keine sind, oder es werden solche Imperfektionen gerade nicht erkannt. Eine verschmutzte Paraffiniereinrichtung kann den Wachsauftrag negativ beeinflussen.In the case of a winding machine, the contamination may relate, for example, to the thread tensioner, the measuring head of the thread cleaner or the waxing device. These contaminations can lead to functional problems in the multi-point textile machine and quality problems of the cheese to be produced. For example, if there is dirt between the plates of a plate clamp, the thread tension can not be adjusted correctly. Contamination of the cleaner's measuring head can lead to incorrect calibration or incorrect readings of the cleaner. Thus, thick, thin or Fremdfasem signals where there are none, or there are just such Imperfections not recognized. A soiled waxing device can adversely affect waxing.

Um derartige Funktionsprobleme respektive Qualitätsprobleme zu reduzieren, ist es bekannt, verschiedene Aggregate in der Vielstellentextilmaschine einzusetzen, die der Reinigung dienen.In order to reduce such functional problems or quality problems, it is known to use various units in the multi-point textile machine, which serve for cleaning.

Ganz grob können diese Aggregate zur Reinigung in zwei Gruppen unterteilt werden. Zum einen gibt es Einrichtungen, die an jeder Arbeitsstelle einer Vielstellentextilmaschine vorhanden sind, und zum anderen gibt es Wanderaggregate, die entlang der Arbeitsstellen verfahrbar sind. Die Wanderaggregate unterscheiden sich zum Teil in ihren Funktionen, je nachdem an welcher Art der Textilmaschine sie eingesetzt werden. Allen Wanderaggregaten gemein ist jedoch, dass sie zur Reinigung der Vielstellentextilmaschine eingesetzt werden.Very roughly, these aggregates can be divided into two groups for cleaning. On the one hand, there are facilities that are available at every workstation of a multi-purpose textile machine, and on the other there are traveling aggregates, which can be moved along the workplaces. The traveling aggregates differ in part in their functions, depending on which type of textile machine they are used. However, all hiking aggregates have in common that they are used for cleaning the multi-point textile machine.

Ein Wanderaggregat patrouilliert permanent oder in Zeitintervallen entlang der Arbeitsstellen der Vielstellentextilmaschine und saugt Verunreinigungen wie ein Staubsauger ein, während er gleichzeitig bestimmte Stellen der Vielstellentextilmaschine sauberbläst. Der eingesaugte Staub wird in einer speziellen Kammer des Wanderaggregates gesammelt und nach jedem Reinigungszyklus in die Sauganlage der Vielstellentextilmaschine entleert.A traveling aggregate patrols permanently or at intervals along the workplaces of the multi-function textile machine and sucks impurities such as a vacuum cleaner while at the same time cleanly blowing certain parts of the multi-function textile machine. The sucked dust is collected in a special chamber of the traveling aggregate and emptied into the suction system of the multi-function textile machine after each cleaning cycle.

Parallel dazu gibt es eine Entstaubung, die den Staub beim Abspulvorgang direkt am Entstehungsort absaugt. Diese in der unmittelbaren Nähe der Ablaufspule angeordnete Absaugung kann über eine einstellbare Drehzahlregelung in ihrer Saugleistung eingestellt werden.In parallel, there is a dedusting, which sucks the dust during unwinding directly at the place of origin. This arranged in the immediate vicinity of the drainage coil suction can be adjusted via an adjustable speed control in their suction power.

Darüber hinaus werden über speziell angeordnete Blasdüsen gezielt besonders schmutzempfindliche Einrichtungen der Arbeitsstelle sauber geblasen. Dies geschieht über eine separate Druckeinrichtung, an die jede Arbeitsstelle angeschlossen ist. Die Intensität der Reinigung durch die Blasdüsen kann durch die Anzahl und die Länge der Blasimpulse beeinflusst werden.In addition, specifically dirt-sensitive devices of the workplace are blown clean by specially arranged nozzles. This is done via a separate printing device to which each job is connected. The intensity of the cleaning by the blowing nozzles can be influenced by the number and the length of the blowing impulses.

Die DE 41 315 25 A1 offenbart einen Wanderreiniger, der oberhalb einer Spulmaschine auf einer längs zu der Spulmaschine angeordneten Fahrschiene verfahrbar ist. Der Wanderreiniger bläst einerseits über Blasschläuche und Blasdüsen Luft auf die Spulmaschine, während er andererseits mit beidseitig der Längsseite der Textilmaschine mitgeführten Saugschläuchen den aufgewirbelten Staub ansaugt.The DE 41 315 25 A1 discloses a traveling cleaner, which is movable above a winder on a longitudinally arranged to the winder drive rail. On the one hand, the traveling cleaner blows air onto the winding machine via blower hoses and blowing nozzles, while, on the other hand, it sucks in the upset dust with suction hoses entrained on both sides of the longitudinal side of the textile machine.

Des Weiteren wird in der DE 41 315 25 A1 beschrieben, dass oberhalb der Ablaufspule ein Lufteinlass angeordnet ist. Dieser Lufteinlass ist derart ausgebildet, dass entlang der Ablaufspule eine Luftströmung entsteht. Der beim Ablaufen des Fadens entstehende Staub wird durch die Luftströmung mitgerissen und in den Lufteinlass eingesaugt.Furthermore, in the DE 41 315 25 A1 described that an air inlet is arranged above the delivery bobbin. This air inlet is designed such that an air flow arises along the delivery coil. The while draining the thread The resulting dust is entrained by the air flow and sucked into the air inlet.

Durch die OS-29 19 768 A1 ist es bekannt, seitlich neben der Ablaufspule ein oder mehrere Ansaugöffnungen anzuordnen. Zusätzlich können besondere Blasdüsen vorteilhaft sein, die gegen mit dem Faden in Berührung stehende Maschinenteile gerichtet sind.By the OS-29 19 768 A1 It is known to arrange one or more suction openings laterally next to the delivery bobbin. In addition, special tuyeres may be advantageous which are directed against machine parts in contact with the thread.

Ein Beispiel dieser besonderen Blasdüsen wird beispielsweise in der DE 10 2005 028 751 A1 beschrieben. Im Bodenbereich des stationären Gehäuses der Paraffiniereinrichtung ist eine Blasdüsenanordnung installiert, die an eine Überdruckquelle angeschlossen und mittels eines Ventils definiert ansteuerbar ist. Das Ventil wird vom Arbeitsstellenrechner angesteuert.An example of these special nozzles is for example in the DE 10 2005 028 751 A1 described. In the bottom region of the stationary housing of the paraffining device, a blower nozzle assembly is installed, which is connected to an overpressure source and can be controlled by means of a valve. The valve is controlled by the workstation computer.

Für Spinnmaschinen gibt es ähnliche Wanderaggregate, die permanent oder zyklisch die Reinigung vornehmen.For spinning machines, there are similar traveling aggregates that perform permanent or cyclic cleaning.

Für Offenend-Rotorspinnmaschinen ist durch die DE 26 29 161 C2 zum Beispiel eine Reinigungseinrichtung für Offenend-Spinneinheiten bekannt, die auf einem fahrbaren Wanderaggregat angeordnet ist und mechanische Reinigungswerkzeuge und/oder Blasdüsen aufweist.For open-end rotor spinning machines is through the DE 26 29 161 C2 For example, a cleaning device for open-end spinning units is known, which is arranged on a mobile traveling aggregate and has mechanical cleaning tools and / or blowing nozzles.

Die mechanischen Reinigungswerkzeuge können, gemäß der DE 26 29 161 C2 , in die Fasersammelrille des Spinnrotors geschwenkt werden. Zur Unterstützung der mechanischen Reinigung kann außerdem über eine Düse zusätzlich Druckluft in den Spinnrotor geblasen werden. Des Weiteren kann in einem geringen Abstand vor dem Spinnrotor zusätzlich eine unterdruckbeaufschlagbare Abdeckung positioniert werden, über die die abgelösten Schmutzpartikel abgesaugt wird.The mechanical cleaning tools can, according to the DE 26 29 161 C2 , are pivoted into the fiber collecting groove of the spinning rotor. In addition, to assist the mechanical cleaning, compressed air can be blown into the spinning rotor via a nozzle. Furthermore, at a small distance in front of the spinning rotor, an underpressurable cover can additionally be positioned, via which the detached dirt particles are sucked off.

Durch die CH 686 191 A5 wird ein Wanderreiniger für eine Ringspinnmaschine offenbart. Ein derartiger Wanderreiniger besitzt einen verfahrbaren Rahmen mit zwei seitlichen, also auf der Längsseite der Ringspinnmaschine angeordneten verfahrbaren Schenkeln. In den Schenkeln befinden sich Leitungen zur Heranführung von Blasluft und zur Abführung der mit Fasern beladenen Abluft.By the CH 686 191 A5 a traveling cleaner for a ring spinning machine is disclosed. Such a traveling cleaner has a movable frame with two lateral, so arranged on the longitudinal side of the ring spinning machine movable legs. In the legs there are lines for the supply of blast air and for the discharge of fiber-laden exhaust air.

Die vorstehend zum Stand der Technik beschriebenen Verfahren und Vorrichtungen zur Reinigung von Vielstellentextilmaschinen weisen allerdings insgesamt den Nachteil auf, dass die Reinigungsparameter manuell in eine Steuereinrichtung eingegeben werden müssen. Werden keine oder nicht die optimalen Reinigungsparameter ausgewählt, so kann das entweder zu erhöhter Verschmutzung und dadurch bedingten Fehlfunktionen sowie Qualitätsproblemen, oder zu einer Energieverschwendung durch Überreinigung führen. Einzugebende Parameter sind beispielsweise Zeitintervalle der Wiederholung, Höhe der Saugluft- oder Druckluftleistung oder die Anzahl der Reinigungs-Blasimpulse innerhalbs eines Reinigungszyklus.However, the methods and devices for cleaning multi-function textile machines described above with regard to the prior art have the disadvantage that the cleaning parameters have to be entered manually into a control device. If no or not the optimum cleaning parameters are selected, this can lead either to increased contamination and resulting malfunctions as well as quality problems, or to an energy waste due to overcleaning. Parameters to be entered are, for example, time intervals of the repetition, the amount of suction air or compressed air power or the number of cleaning blow pulses within a cleaning cycle.

Trotz der automatisierten Reinigung und der bekannten Optimierungsstrategien kann es aufgrund von manuell gewählten Eingaben vorkommen, dass die Reinigung nicht optimal durchgeführt wird.Despite the automated cleaning and well-known optimization strategies, it may be due to manually selected inputs that the cleaning is not performed optimally.

Es ist deshalb die Aufgabe der vorliegenden Erfindung, eine Vielstellentextilmaschine vorzuschlagen, an der eine verbesserte Reinigung der Arbeitsstellen erfolgt.It is therefore the object of the present invention to propose a multi-purpose textile machine, on which an improved cleaning of the jobs takes place.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.

Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous developments of the invention are the subject of the dependent claims.

Zur Lösung der Aufgabe sind gemäß Anspruch 1 Einrichtungen vorhanden, die sensorisch die Verschmutzung der Arbeitsstellen erfassen, das Ergebnis an eine Steuereinrichtung weiterleiten, und die Steuereinrichtung dazu eingerichtet ist, in Abhängigkeit von der Verschmutzung die Beaufschlagung der Öffnungen mit Saug- oder Druckluft bedarfsgerecht anzusteuern.To solve the problem, facilities are provided according to claim 1, which sensory detect the pollution of the jobs, forward the result to a control device, and the control device is adapted to control depending on the pollution, the admission of the openings with suction or compressed air as needed.

Der Vorteil einer sensorüberwachten Vielstellentextilmaschine ist, dass die Reinigungsaggregate anhand objektiver Kriterien gezielt eingesetzt werden können. Dazu werden ein oder mehrere Sensoren an verschmutzungskritischen Punkten der Vielstellentextilmaschine angeordnet, die den jeweiligen Verschmutzungsgrad überwachen. Wird von einem der Sensoren eine Verschmutzung detektiert, so wird das Ergebnis an eine Steuereinrichtung weitergeleitet. Daraufhin initiiert die Steuereinrichtung, dass die an dem jeweiligen Wanderaggregat oder an der entsprechenden Arbeitsstelle angebrachten Öffnungen entweder mit Saug- oder Druckluft beaufschlagt werden. Die manuelle Eingabe des Bedieners in die Steuereinrichtung entfällt und die Reinigung wird erfindungsgemäß unabhängig vom subjektiven Empfinden des Bedieners.The advantage of a sensor-monitored multi-point textile machine is that the cleaning units can be used selectively based on objective criteria. For this purpose, one or more sensors are arranged on pollution-critical points of the multi-point textile machine, which monitor the respective degree of contamination. If contamination is detected by one of the sensors, the result is forwarded to a control device. Then, the controller initiates that attached to the respective hiking aggregate or at the corresponding job Openings are subjected to either suction or compressed air. The manual input of the operator in the control device is eliminated and the cleaning according to the invention is independent of the subjective feeling of the operator.

Auf diese Weise wird die Vielstellentextilmaschine zu jeder Zeit bestmöglich gereinigt, ohne dass die Gefahr von Ausfällen aufgrund einer nicht optimal durchgeführten Reinigung oder einer Überreinigung besteht.In this way, the multi-point textile machine is cleaned as best as possible at any time, without the risk of failure due to a not optimally performed cleaning or over cleaning.

Vorzugsweise sind, wie in Anspruch 2 beschrieben, die Öffnungen jeweils an gemeinsame Druck- oder Saugluftleitungen angeschlossen, die zentral mit Saug- oder Druckluft versorgt werden.Preferably, as described in claim 2, the openings are each connected to common pressure or suction air lines, which are supplied centrally with suction or compressed air.

Dadurch wird der Reinigungsvorgang flexibel gestaltet, weil jede einzelne Öffnung je nach Bedarf entsprechend beaufschlagt werden kann. Eine Öffnung kann beispielsweise auch zuerst mit Druckluft beaufschlagt werden, so dass ein bestimmter Bereich von Flusen und Verschmutzungen frei gepustet wird, um dann im Anschluss daran mit Saugluft beaufschlagt zu werden, so dass die zuvor aufgewirbelten Flusen und Verschmutzungen eingesaugt werden, um zu verhindern, dass sie sich erneut auf der Vielstellentextilmaschine ablegen.As a result, the cleaning process is made flexible, because each opening can be acted upon as needed. For example, an opening may also be first pressurized with compressed air so that a certain area of lint and debris is blown freely, and then thereafter supplied with suction air, so that the previously agitated fluff and debris are sucked in to prevent that they put themselves on the multi-point textile machine again.

Insbesondere ist, gemäß Anspruch 3, die Verbindung zwischen den Öffnungen und der jeweiligen Druck- oder Saugluftleitung einzeln oder gruppenweise auf Basis von Steuersignalen der Steuereinrichtung schaltbar.In particular, according to claim 3, the connection between the openings and the respective pressure or suction air line individually or in groups on the basis of control signals of the control device switchable.

Je nach dem Verschmutzungsaufkommen kann es sinnvoll sein, entweder die einzelne Arbeitsstelle oder aber einen größeren Arbeitsbereich, wie beispielsweise eine Sektion, zu reinigen. Wichtig ist, dass erfindungsgemäß dies objektiv anhand der auftretenden Verschmutzung gesteuert wird.Depending on the amount of contamination, it may be useful to clean either the individual work site or a larger work area, such as a section. It is important that according to the invention this is controlled objectively on the basis of the pollution occurring.

Wie in Anspruch 4 dargelegt, ist die Steuereinrichtung darauf eingerichtet, das Verfahren des Wanderaggregats bedarfsgerecht zu steuern.As set out in claim 4, the control device is adapted to control the method of the traveling aggregate as needed.

Je nachdem, ob das Wanderaggregat, ein so genannter Wanderreiniger, der beispielsweise an Spulmaschinen oder Ringspinnmaschinen zum Einsatz kommt, oder zum Beispiel ein so genannter Wechslerreinigerwagen, der üblicherweise an Offenend-Rotorspinnmaschinen verwendet wird, ist, muss das entsprechende Reinigungsverfahren von der Steuereinrichtung bedarfsgerecht gesteuert werden, um die erfindungsgemäßen Vorteile zu erhalten.Depending on whether the traveling aggregate, a so-called traveling cleaner, which is used, for example, on winding machines or ring spinning machines, or for example a so-called changer cleaner car, which is usually used on open-end rotor spinning, is the appropriate cleaning method be controlled as needed by the controller to obtain the advantages of the invention.

Gemäß Anspruch 5 ist die Einrichtung zur sensorischen Erfassung der Verschmutzung eine Reflexionslichtschranke.According to claim 5, the device for sensory detection of contamination is a reflection light barrier.

Lichtschranken sind grundsätzlich in der Lage, die durch ein Objekt hervorgerufene Änderung der Lichtintensität zu registrieren und in elektrische Signale umzuwandeln, die zur weiteren Verarbeitung geeignet sind.Photocells are basically capable of registering the change in light intensity caused by an object and converting it into electrical signals suitable for further processing.

In einer bevorzugten Ausführungsform werden Reflexionslichtschranken verwendet, deren Vorteil darin besteht, dass eine elektrische Zuleitung an einem zweiten Ort eingespart werden kann, da Sender und Empfänger räumlich nahe beieinander angeordnet, doch optisch getrennt, in einem Gehäuse integriert sind. Der Sender der Reflexionslichtschranke ist auf eine genau gegenüberliegende Reflexions-Einheit ausgerichtet und schickt Licht aus. Von der Reflexions-Einheit wird der Strahl lediglich reflektiert und an den Empfänger zurückgeleitet.Reflection light barriers are used in a preferred embodiment, the advantage of which is that an electrical supply line can be saved at a second location, since the transmitter and receiver are arranged spatially close to one another but optically separated, integrated in a housing. The transmitter of the reflection light barrier is aligned with an exactly opposite reflection unit and emits light. From the reflection unit, the beam is merely reflected and returned to the receiver.

Grundsätzlich sind auch andere Sensoren im Rahmen der Erfindung denkbar, die in der Lage sind, die Verschmutzung zu detektieren.In principle, other sensors within the scope of the invention are also conceivable which are capable of detecting the contamination.

Vorteilhafterweise sind, wie im Anspruch 6 beschrieben, Öffnungen in der Nähe von schmutzempfindlichen oder Schmutz emittierenden Einrichtungen der Arbeitsstelle angeordnet.Advantageously, as described in claim 6, openings are arranged in the vicinity of dirt-sensitive or dirt-emitting devices of the workplace.

Durch eine derartige Konstruktion ist gewährleistet, dass gerade an den Einrichtungen, die besonders schmutzempfindlich sind, wie beispielsweise der Messkopf des Garnreinigers, Funktionsstörungen vermieden werden. Zur Vereinfachung der Reinigungsabläufe bietet es sich an, direkt an diesen Stellen Öffnungen anzuordnen, so dass hier ohne den Einsatz eines Wanderaggregates kurzfristig und gezielt gereinigt werden kann.Such a construction ensures that it is precisely at the facilities that are particularly dirt-sensitive, such as the measuring head of the yarn cleaner, malfunctions are avoided. To simplify the cleaning processes, it makes sense to arrange openings directly at these points, so that it can be cleaned quickly and specifically without the use of a walking aggregate.

Auch macht es Sinn, solche Öffnungen in Bereichen von Schmutz verursachenden Einrichtungen anzuordnen, so dass hier Flusen und Verschmutzungen abgesaugt werden können, bevor sie sich verteilen und auf der Vielstellentextilmaschine ablegen. Des Weiteren ist es vorteilhaft, gemäß Anspruch 7, wenn Öffnungen in der Nähe der Ablaufspule angeordnet sind.It also makes sense to arrange such openings in areas of dirt causing facilities, so that here lint and dirt can be sucked off before they spread and put on the multi-point textile machine. Furthermore, it is advantageous according to claim 7, when openings are arranged in the vicinity of the delivery bobbin.

Wie bereits ausgeführt, ist es vorteilhaft, wenn Flusen und Verschmutzung bereits an dem Ort des Entstehens abgesaugt werden. Auf diese Weise wird vermieden, dass sich die Verunreinigungen in der Spinnerei verteilen und sich auf den Vielstellentextilmaschinen ablegen.As already stated, it is advantageous if lint and dirt are already sucked off at the point of origin. In this way it is avoided that the impurities distribute in the spinning mill and settle on the multi-point textile machines.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention will be explained in more detail with reference to an embodiment shown in the drawing.

Es zeigt:

  • Figur 1 Arbeitsstelle einer Vielstellentextilmaschine mit Sensoren und Öffnungen.
It shows:
  • FIG. 1 Workplace of a multi-point textile machine with sensors and openings.

In Figur 1 ist in Seitenansicht schematisch eine Arbeitsstelle 2 einer Vielstellentextilmaschine, im vorliegenden Fall einer so genannten Spulmaschine 1, dargestellt.In FIG. 1 is a side view schematically a job 2 a multi-point textile machine, in the present case, a so-called winder 1, shown.

Solche Spulmaschinen 1 weisen eine Vielzahl gleichartiger, in Reihe nebeneinander angeordneter Arbeitsstellen 2 auf, auf denen, wie bekannt und daher nicht näher erläutert, Ablaufspulen 3, die relativ wenig Garnvolumen aufweisen, zu großvolumigen Kreuzspulen 5 umgespult werden.Such winding machines 1 have a plurality of similar, in series juxtaposed jobs 2, on which, as is known and therefore not explained in detail, feed bobbins 3, which have relatively little yarn volume, are rewound to large-volume cheeses 5.

Der laufende Faden 16 wird während des Umspulens außerdem, wie bekannt, auf eventuelle Garnfehler hin überwacht, die gegebenenfalls ausgereinigt werden. Dazu weist der sogenannte Reiniger eine Messkopf- 20 und eine Schneideinrichtung 22 auf.The running thread 16 is also monitored during rewinding, as is known, for possible yarn defects, which are optionally cleaned. For this purpose, the so-called cleaner has a measuring head 20 and a cutting device 22.

Außerdem wird der Faden 16 während des Umspulprozesses mit einem Paraffinauftrag versehen. Das heißt, der Faden 16 wird über eine Paraffiniereinrichtung 19 geleitet, die dafür sorgt, dass der Reibwert des Fadens 16 reduziert wird. Das heißt, durch einen solchen Paraffinauftrag werden die Lauf- und Gleiteigenschaften des Fadens 16 deutlich verbessert.In addition, the thread 16 is provided with a paraffin coating during the rewinding process. That is, the thread 16 is passed through a paraffining device 19, which ensures that the coefficient of friction of the thread 16 is reduced. That is, by such a paraffin application, the running and sliding properties of the thread 16 are significantly improved.

Die Kreuzspulen 5 werden nach ihrer Fertigstellung mittels eines (nicht dargestellten) selbsttätig arbeitenden Serviceaggregates auf eine maschinenlange Kreuzspulentransporteinrichtung 7 übergeben und zu einer maschinenendseitig angeordneten Spulenverladestation oder dergleichen transportiert.The cheeses 5 are after their completion by means of a (not shown) automatically operating service unit on a machine-length cross-coil transport device Passed 7 and transported to a machine end side arranged Spulenverladestation or the like.

Wie in Figur 1 weiter angedeutet, sind solche Spulmaschinen 1 oft mit einem Spulenund Hülsentransportsystem 6 ausgestattet, in dem, auf Transporttellem 11, die Ablaufspulen 3, beziehungsweise die Leerhülsen umlaufen. Von einem solchen Spulen- und Hülsentransportsystem 6 sind in Figur 1 lediglich die Kopszuführstrecke 24, die reversierend antreibbare Speicherstrecke 25, eine der zu den Spulstellen 2 führenden Quertransportstrecken 26 sowie die Hülsenrückführstrecke 27 dargestellt.As in FIG. 1 further indicated, such winding machines 1 are often equipped with a bobbin and sleeve transport system 6, in which, on Transporttellem 11, the delivery bobbins 3, or circulate the empty tubes. Of such a bobbin and sleeve transport system 6 are in FIG. 1 only the Kopszuführstrecke 24, the reversibly driven storage section 25, one of the leading to the winding units 2 transverse transport sections 26 and the sleeve return path 27 shown.

Die einzelnen Arbeitsstellen 2 verfügen des Weiteren über verschiedene Einrichtungen, die einen ordnungsgemäßen Betrieb derartiger Arbeitsstellen gewährleisten. Derartige Einrichtungen sind an sich bekannt und daher in der Figur 1 nur angedeutet.The individual jobs 2 also have various facilities that ensure the proper operation of such jobs. Such devices are known per se and therefore in the FIG. 1 only hinted.

Eine dieser bekannten Einrichtungen ist beispielsweise die Spulvorrichtung 4, die einen um eine Schwenkachse 12 beweglich gelagerten Spulenrahmen 8 aufweist. Gemäß vorliegendem Ausführungsbeispiel liegt die Kreuzspule 5 während des Spulprozesses mit ihrer Oberfläche auf einer Antriebstrommel 9 auf und wird von dieser Antriebstrommel 9 über Reibschluss mitgenommen.One of these known devices is, for example, the winding device 4, which has a coil frame 8 movably mounted about a pivot axis 12. According to the present embodiment, the cheese 5 is located during the winding process with its surface on a drive drum 9 and is driven by this drive drum 9 via frictional engagement.

Zur Changierung des Fadens 16 während des Spulprozesses ist eine Fadenchangiereinrichtung 10 vorgesehen. Eine solche, ebenfalls bekannte und in der Figur 1 nur schematisch angedeutete Fadenchangiereinrichtung 10 verfügt beispielsweise über einen Fadenführer 13 mit einem fingerartig ausgebildeten Fadenverlegehebel.For traversing the thread 16 during the winding process a Fadenchangiereinrichtung 10 is provided. Such, also known and in the FIG. 1 only schematically indicated Fadenchangiereinrichtung 10 has, for example, a yarn guide 13 with a finger-like thread laying lever.

Weiterhin ist noch die Spleißeinrichtung 18 und der Fadenspanner 17 angedeutet. Der Fadenspanner 17 ist im dargestellten Ausführungsbeispiel als Tellerspanner ausgebildet. Dieser sorgt während des normalen Spulbetriebs für die nötige Fadenspannung und klemmt bei einer Fadenunterbrechung den Unterfaden.Furthermore, the splicing device 18 and the thread tensioner 17 is still indicated. The thread tensioner 17 is formed in the illustrated embodiment as a plate tensioner. This ensures during the normal winding operation for the necessary thread tension and clamps at a thread interruption the bobbin thread.

Mit dem Bezugszeichen 40 ist eine arbeitsstelleneigene Blaseinrichtung angedeutet. Die einzelnen Öffnungen 41, 42, 43, 44 und 45 sind mittels des Elektromagnetventils 38 an die kombinierte Druck- und Saugluftquelle 37 anschließbar. Das Elektromagnetventil 38 wird von der arbeitsstelleneigenen Steuereinrichtung 28 angesteuert. Die Blaseinrichtung 40 weist insgesamt fünf Öffnungen 41, 42, 43, 44 und 45 auf, wobei eine erste Öffnung 41 auf die Paraffiniereinrichtung 19, eine zweite Öffnung 42 auf den Reinigermesskopf 20, seinen Messschlitz und die Schneideinrichtung 22 und eine dritte Öffnung 43 auf den Fadenspanner 17 gerichtet ist. Die vierte Öffnung 44 und die fünfte Öffnung 45 befinden sich im Bereich der Ablaufspule 3.The reference numeral 40 indicates a workstation's own blowing device. The individual openings 41, 42, 43, 44 and 45 can be connected by means of the solenoid valve 38 to the combined pressure and suction air source 37. The solenoid valve 38 is driven by the workstation's own control device 28. The blowing device 40 has a total of five openings 41, 42, 43, 44 and 45, wherein a first opening 41 on the waxing device 19, a second opening 42 on the cleaner measuring head 20, its measuring slot and the cutting device 22 and a third opening 43 is directed to the thread tensioner 17. The fourth opening 44 and the fifth opening 45 are located in the region of the delivery reel 3.

Des Weiteren ist jeweils eine Reflexionslichtschranke 46 im Bereich der Paraffiniereinrichtung 19, des Reinigermesskopfes 20, des Fadenspanners 17 sowie in der Nähe der Ablaufspule 3 angeordnet.Furthermore, in each case a reflection light barrier 46 is arranged in the region of the paraffining device 19, the cleaner measuring head 20, the thread tensioner 17 and in the vicinity of the delivery reel 3.

Die Spulstelle 2 weist außerdem eine Bedieneinheit 30 auf, die über eine nicht dargestellte Kommunikationsleitung mit der Steuereinrichtung 28 verbunden ist. Die Steuereinrichtung 28 steuert und überwacht außerdem über ebenfalls nicht dargestellte Leitungen die oben beschriebenen Einrichtungen der Spulstelle 2. Mittels der Bedieneinheit 30 können dem Bediener Zustände der Spulstelle 2, wie beispielsweise ein stattfindender Reinigungsvorgang, angezeigt werden. Dazu weist die Bedieneinheit 30 eine Signallampe 31 auf.The winding unit 2 also has an operating unit 30, which is connected via a communication line, not shown, with the control device 28. The control device 28 also controls and monitors via lines not shown also the above-described means of the winding unit 2. By means of the control unit 30, the operator states of the winding unit 2, such as an ongoing cleaning process, are displayed. For this purpose, the operating unit 30 has a signal lamp 31.

Erfindungsgemäß detektieren die Reflexionslichtschranken 46 ihre jeweiligen Bereiche. Wird eine zunehmende Verschmutzung des Fadenspanners 17 erfasst, wird ein entsprechendes Signal an die Steuereinrichtung 28 gesendet. Daraufhin initiiert die Steuereinrichtung 28 die Beaufschlagung der Öffnung 43 mit Druckluft, so dass anhaftende Flusen und Verschmutzungen von dem Fadenspanner 17 abgeblasen werden. Im Anschluss daran wird die Öffnung 43 mit Saugluft beaufschlagt und die kurz zuvor aufgewirbelten Flusen und Verschmutzungen eingesaugt.According to the invention, the reflection light barriers 46 detect their respective areas. If an increasing contamination of the thread tensioner 17 is detected, a corresponding signal is sent to the control device 28. Subsequently, the control device 28 initiates the pressurization of the opening 43 with compressed air, so that adhering lint and dirt are blown off the thread tensioner 17. Following this, the opening 43 is acted upon with suction air and sucked in the lint and lint just stirred up.

Detektieren alle Reflexionslichtschranken 46 eine nicht zu tolerierende Verschmutzung, so wird zusätzlich zu der Ansteuerung der arbeitsstelleneigenen Öffnungen 41, 42, 43, 44 und 45 ein entsprechendes Wanderaggregat, im Falle einer Spulmaschine ein (nicht dargestellter) Wanderreiniger, angesteuert, der ebenfalls Öffnungen zur Beaufschlagung mit Saug- oder Druckluft aufweist.If all reflection light barriers 46 detect a contamination that is not to be tolerated, then in addition to the control of the workstation's own openings 41, 42, 43, 44 and 45, a corresponding traveling aggregate, in the case of a winder, a traveling cleaner (not shown), which likewise has openings for admission having suction or compressed air.
