Description

Die Erfindung betrifft einen Hülsengreifer für ein Kreuzspulenwechselaggregat gemäß dem Oberbegriff des Anspruches 1.The invention relates to a tube gripper for a cheese change unit according to the preamble of claim 1.

Im Zusammenhang mit Kreuzspulen herstellenden Textilmaschinen, zum Beispiel Kreuzspulautomaten, sind seit langem so genannte Kreuzspulenwechselaggregate bekannt.In connection with cross-wound producing textile machines, for example automatic spooling machines, so-called cross-spool changing units have long been known.

Solche Kreuzspulenwechselaggregate sind entlang der Arbeitsstellen der Textilmaschinen verfahrbare Bedienläufer, die im Bedarfsfall an den Arbeitsstellen selbsttätig helfend eingreifen. Ein solcher Bedarfsfall ist beispielsweise gegeben, wenn an einer Arbeitsstelle die Kreuzspule eine vorgegebene Größe erreicht hat. In einem solchen Fall läuft das Kreuzspulenwechselaggregat zu der betreffenden Arbeitsstelle, positioniert sich dort und wechselt die fertiggestellte Kreuzspule gegen eine neue Leerhülse aus.Such cheese change units are along the workstations of the textile machines movable operator, which intervene automatically when needed at the jobs helping. Such a requirement is given, for example, if the cross-wound bobbin has reached a predetermined size at a workstation. In such a case, the cheese change unit runs to the relevant job, positions itself there and exchanges the finished cross-wound bobbin for a new empty tube.

Derartige Kreuzspulenwechselaggregate, die beispielsweise in der DE 195 24 946 B4 und der DE 10 2007 036 696 A1 beschrieben sind, weisen jeweils eine Vielzahl von Handhabungseinrichtungen auf, die während eines Wechselvorganges entsprechend einem vorgegebenen Programm zum Einsatz kommen.Such cross-coil changing units, for example, in the DE 195 24 946 B4 and the DE 10 2007 036 696 A1 are described, each have a variety of handling devices that come during a change process according to a predetermined program used.

Solche Kreuzspulenwechselaggregate verfügen zum Beispiel über einen Rahmenöffner, einen Rahmenheber, eine Spulenführungseinrichtung sowie einen Hülsengreifer.Such cross-coil changing units have, for example, a frame opener, a frame lifter, a coil guide device and a tube gripper.

Mit dem Hülsengreifer entnimmt das Kreuzspulenwechselaggregat im Zuge des Wechselvorganges aus einem arbeitsstelleneigenen Leerhülsenspeicher eine Leerhülse und wechselt diese nach dem Ausstoßen der fertiggestellten Kreuzspule in den Spulenrahmen der betreffenden Arbeitsstelle ein.With the tube gripper removes the cheese change unit in the course of the change process from a working empty empties storage an empty tube and changes them after ejecting the finished cheese in the creel of the relevant job.

In der DE 195 24 946 B4 ist beispielsweise ein Kreuzspulenwechselaggregat beschrieben, das über einen Hülsengreifer verfügt, der einen prismatisch ausgebildeten, mittels eines Stellmechanismus' mechanisch justierbaren Hülsenhalter zum Positionieren einer Leerhülse sowie einen mittels eines Pneumatikzylinders schwenkbaren Greiferfinger zum Fixieren der Leerhülse auf dem Hülsenhalter aufweist.In the DE 195 24 946 B4 For example, a cross-coil changing unit is described, which has a tube gripper, which has a prismatic, by means of an adjusting mechanism mechanically adjustable sleeve holder for positioning an empty tube and a pivotable by means of a pneumatic cylinder gripper fingers for fixing the empty tube on the sleeve holder.

Bei einem derartig ausgebildeten Hülsengreifer ist die spätere Hülsenübergabestellung der Leerhülse stets durch die Stellung des prismatisch ausgebildeten Hülsenhalters vorgegeben.In such a trained tube gripper, the subsequent sleeve transfer position of the empty tube is always determined by the position of the prismatic sleeve holder.

Das bedeutet, bei Kreuzspulenwechselaggregaten, die mit derartig ausgebildeten Hülsengreifern ausgestattet sind, muss, wenn es an der zugehörigen Textilmaschine zu einem Partiewechsel kommt und im Zuge dieses Partiewechsels beispielsweise von Kreuzspulen mit zylindrischen Hülsen auf Kreuzspulen mit konischen Hülsen umgestellt wird, zur Anpassung an das neue Hülsenformat auch die Stellung des Hülsenhalters manuell neu eingestellt werden.This means that in cross-wound bobbin changing units, which are equipped with such trained tube grippers, when it comes to the associated textile machine to a game change and in the course of this lot change, for example, from cheeses with cylindrical sleeves on cheeses with conical sleeves, to adapt to the new Sleeve format and the position of the sleeve holder manually be reset.

Ein Kreuzspulenwechselaggregat mit einem vergleichbaren Hülsengreifer ist auch in der DE 10 2007 036 696 A1 beschrieben. Auch hier besteht der Hülsengreifer aus einem an einem Basiskörper des Hülsengreifers angeordneten prismatisch ausgebildeten Hülsenhalter und einem mittels eines Pneumatikzylinders bewegbaren Greiferfinger, der auf eine im Hülsenhalter positionierte Leerhülse absenkbar ist.A cheese change unit with a comparable tube gripper is also in the DE 10 2007 036 696 A1 described. Again, the tube gripper consists of a arranged on a base body of the tube gripper prismatic sleeve holder and a movable by means of a pneumatic cylinder gripper fingers, which can be lowered onto an empty tube positioned in the sleeve holder.

Diese Literaturstelle enthält allerdings keine Aussagen darüber, ob oder wie dieser bekannte Hülsengreifer auf unterschiedliche Hülsenformate einstellbar ist.However, this reference contains no statements as to whether or how this known tube gripper is adjustable to different sleeve formats.

Die bekannten Kreuzspulenwechselaggregate haben sich in der Praxis zwar bewährt, weisen aber den Nachteil auf, dass ihre Hülsengreifer bei einem Wechsel des Hülsenformats stets manuell neu eingestellt werden müssen. Außerdem können derartige Kreuzspulenwechselaggregate stets nur eine Leerhülsensorte handhaben, mit der Folge, dass derartige Kreuzspulenwechselaggregate nur bei einem Einpartienbetrieb einer Textilmaschine einsetzbar sind.The known cross-coil changing units have proven themselves in practice, but have the disadvantage that their sleeve grippers always have to be readjusted manually when changing the sleeve format. In addition, such cheese change units can always handle only one empty tube type, with the result that such cross-coil changing units can be used only in a one-part operation of a textile machine.

Das heißt, wenn eine Kreuzspulen herstellende Textilmaschine im Mehrpartienbetrieb arbeiten soll, sind zur Versorgung der Arbeitsstellen dieser Textilmaschine stets wenigstens zwei derartig ausgebildete Kreuzspulenwechselaggregate notwendig.In other words, if a textile machine producing cross-wound bobbins is to operate in multi-batch operation, at least two cross-bobbin changing units of this type are always necessary to supply the workstations of this textile machine.

In der Vergangenheit sind bereits Kreuzspulenwechselaggregate vorgeschlagen worden, die es ermöglichen, ohne aufwendige Umbauarbeiten unterschiedliche Hülsenformate zu handhaben.In the past, cross-coil changing units have already been proposed, which make it possible to handle different sleeve formats without costly conversion work.

Des Weiteren sind im Zusammenhang mit Kreuzspulautomaten bereits Hülsenzubringer entwickelt worden, die sich beim Greifen einer Leerhülse automatisch an das jeweilige Hülsenformat anpassen.Furthermore, sleeve feeders have already been developed in connection with reciprocating machines, which automatically adapt to the respective tube format when gripping an empty tube.

In der EP 0 126 352 B1 ist beispielsweise ein Kreuzspulenwechselaggregat beschrieben, bei dem der Hülsengreifer an einem speziellen, schwenkbar gelagerten Zwischenrahmen des Kreuzspulenwechselaggregats angeordnet ist.In the EP 0 126 352 B1 For example, a cross-coil changing unit is described in which the tube gripper is arranged on a special, pivotally mounted intermediate frame of the cross-coil changing unit.

Dieser Zwischenrahmen des Kreuzspulenwechselaggregats kann, je nachdem, ob zylindrische oder konische Leerhülsen gehandhabt werden müssen, in eine erste oder in eine zweite Arbeitsstellung verschwenkt werden.This intermediate frame of the cheese change unit can, depending on whether cylindrical or conical empty tubes must be handled, are pivoted in a first or in a second working position.

Derartige Kreuzspulenwechselaggregate sind in ihrem konstruktiven Aufbau allerdings recht komplex, mit der Folge, dass die Fertigung solcher Kreuzspulenwechselaggregate recht kostenintensiv ist.Such cross-coil changing units are quite complex in their structural design, with the result that the production of such cheese change units is quite expensive.

Kreuzspulenwechselaggregate mit Hülsengreifern, die an einem schwenkbar gelagerten Zwischenrahmen angeordnet sind, konnten sich in der Praxis daher nicht durchsetzen.Cross-coil changing units with tube grippers, which are arranged on a pivotally mounted intermediate frame, therefore could not prevail in practice.

Durch die EP 1 197 463 B1 ist ein Hülsenzubringer bekannt, der mit einem speziellen Hülsengreifer ausgestattet ist.By the EP 1 197 463 B1 a sleeve feeder is known, which is equipped with a special tube gripper.

Dieser bekannte Hülsengreifer, der auch an Kreuzspulenwechselaggregaten einsetzbar ist, ist so ausgebildet, dass er sich automatisch an den Durchmesser sowie die Form einer aufgenommenen Leerhülse anpasst, wobei außerdem die Mittenlängsachse der aufgenommenen Leerhülse, unabhängig von der Form oder dem Durchmesser der Leerhülse, während der Hülsenüberführung so verlagert wird, dass sie in einer Hülsenübergabeposition mit der Rotationsachse der am Spulenrahmen einer Arbeitsstelle angeordneten Hülsenaufnahmeteller übereinstimmt.This known tube gripper, which is also applicable to cheese change units, is designed so that he himself automatically adjusts to the diameter and the shape of an accommodated empty tube, wherein also the center longitudinal axis of the recorded empty tube, regardless of the shape or the diameter of the empty tube, during the sleeve transfer is shifted so that it in a sleeve transfer position with the axis of rotation of the coil frame of a job arranged sleeve receiving plate coincides.

Diese bekannten Hülsenzubringer sind in ihrem mechanischen Aufbau allerdings sehr aufwendig und insbesondere gegenüber den in Spulereien herrschenden Umweltbedingungen, wie zum Beispiel Faserflug, recht empfindlich.However, these known sleeve feeders are very complicated in their mechanical construction and, in particular, very sensitive to the environmental conditions prevailing in winding operations, such as fiber fly.

Auch die Hülsenzubringer gemäß EP 1 197 463 B1 konnte sich in der Praxis daher nicht durchsetzen.Also, the sleeve feeder according to EP 1 197 463 B1 therefore could not prevail in practice.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Hülsengreifer für ein Kreuzspulenwechselaggregat zu entwickeln, der einerseits zuverlässig und ohne zusätzliche Umbauarbeiten das Einwechseln von Leerhülsen unterschiedlicher Hülsenformate in die Spulenrahmen der Arbeitsstellen einer Kreuzspulen herstellenden Textilmaschine ermöglicht und anderseits kostengünstig herstellbar und unempfindlich gegen erschwerte Umweltbedingungen ist.Based on the aforementioned prior art, the present invention seeks to develop a tube gripper for a cheese change unit, on the one hand reliable and without additional modifications the replacement of empty tubes of different sleeve formats in the creel of jobs of a cheese-producing textile machine allows and on the other hand inexpensive to produce and insensitive against harsh environmental conditions.

Diese Aufgabe wird erfindungsgemäß durch einen Hülsengreifer gelöst, wie er im Anspruch 1 beschrieben ist.This object is achieved by a tube gripper, as described in claim 1.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are the subject of the dependent claims.

Die erfindungsgemäße Ausbildung eines Hülsengreifers hat insbesondere den Vorteil, dass bei der Übernahme einer Leerhülse aus einem arbeitsstelleneigenen Leerhülsenspeicher sofort eine zuverlässige Ausrichtung und Fixierung der Rotationsachse der aufgenommenen Leerhülse entsprechend des vorliegenden, vorgegebenen Hülsenformates erfolgt.The inventive design of a tube gripper has the particular advantage that when taking over an empty tube from a working empty empties memory immediately a reliable alignment and fixation of the axis of rotation of recorded empty tube according to the present, predetermined sleeve format.

Das heißt, die beiden beabstandet angeordneten 3-Punkt-Spanneinrichtungen des erfindungsgemäßen Hülsengreifers, die jeweils durch den Hülsenhalter, einen beweglichen Antasthebel sowie einen beweglichen Gegenspannhebel gebildet werden, stellen sicher, dass die Rotationsachse der aufgenommenen Leerhülse, sofort entsprechend ihrem Hülsenformat, das bekannt und in einer Speichereinrichtung des Kreuzspulenwechselaggregats hinterlegt ist, so definiert ausgerichtet wird, dass die Rotationsachse der Leerhülse im Bereich einer Hülsenübergabestellung mit der Rotationsachse der Hülsenaufnahmeteller des Spulenrahmens der betreffenden Arbeitsstelle übereinstimmt.That is, the two spaced arranged 3-point clamping devices of the tube gripper according to the invention, each formed by the sleeve holder, a movable probing lever and a movable counter-clamping lever, ensure that the axis of rotation of the recorded empty tube, immediately according to their sleeve format, the known and is deposited in a storage device of the cheese change unit, is aligned so defined that the axis of rotation of the empty tube in the region of a sleeve transfer position coincides with the axis of rotation of the sleeve receiving plate of the creel of the relevant job.

Ein mit einem erfindungsgemäßen Hülsengreifer ausgestattetes Kreuzspulenwechselaggregat kann daher problemlos nacheinander Leerhülsen verschiedenen Durchmessers und/oder unterschiedlicher Hülsenform (zylindrisch oder konisch) handhaben, das heißt, aus einem arbeitsstelleneigenen Leerhülsenspeicher in eine Hülsenübergabestellung eines zugehörigen Spulenrahmens einer Arbeitsstelle überführen.A cross-coil changing unit equipped with a tube gripper according to the invention can therefore easily handle one after the other empty tubes of different diameter and / or different sleeve shape (cylindrical or conical), that is, transfer from a working empty envelope storage in a sleeve transfer position of an associated creel of a job.

Auch bei einem Mehrpartienbetrieb, bei dem unterschiedliche Hülsenformate gehandhabt werden müssen, sind keinerlei Einstellarbeiten am Hülsengreifer notwendig.Even with a multi-part operation, in which different sleeve formats must be handled, no adjustments to the tube gripper are necessary.

Die vom Hülsengreifer in der Hülsenübergabestellung bereitgehaltene Leerhülse kann von den drehbar gelagerten Hülsenaufnahmetellern des Spulenrahmens beim Schließen des Spulenrahmens sicher übernommen werden.The empty tube held ready by the tube gripper in the sleeve transfer position can be safely taken over by the rotatably mounted sleeve receiving plates of the coil frame when closing the coil frame.

In bevorzugter Ausführungsform weist der Hülsengreifer zwei über eine erste Achse an einem Zentralträger des Hülsengreifers schwenkbar gelagerte Antasthebel sowie zwei an einer zweiten Achse des Zentralträgers schwenkbar gelagerte Gegenspannhebel auf.In a preferred embodiment, the tube gripper has two probing levers pivotally mounted on a central carrier of the tube gripper via a first axis and two counter-clamping levers mounted pivotably on a second axis of the central carrier.

Die beiden Antasthebel sind dabei durch einen Pneumatikzylinder in Richtung der Leerhülse schwenkbar und jeweils mit einem zugehörigen Gegenspannhebel formschlüssig gekoppelt.The two probing levers are pivotable by a pneumatic cylinder in the direction of the empty tube and each positively coupled with an associated counter-tensioning lever.

Das heißt, ein am Antasthebel angeordnetes Gleit- und Führungselement korrespondiert mit einer zugehörigen, in den Gegenspannhebel integrierten Kurvenkontur.That is, a sliding and guide element arranged on the feeler lever corresponds to an associated curve contour integrated into the counter-tensioning lever.

In der Praxis bedeutet dies, dass beim Einschwenken der Antasthebel gleichzeitig auch die zugehörigen Gegenspannhebel mit eingeschwenkt werden und dabei die auf dem Hülsenhalter positionierte Leerhülse definiert ausrichtet und fixiert wird. Die beiden auf die Leerhülse wirkenden Antasthebel und die beiden Gegenspannhebel bilden in Verbindung mit dem Hülsenhalter der Hülsengreifers zwei beabstandet angeordnete 3-Punkt-Spanneinrichtungen, die die Leerhülse sowohl vorschriftsmäßig ausrichten, als auch sicher fixieren.In practice, this means that when pivoting the probing lever at the same time also the associated counter-clamping lever are pivoted with and thereby aligns the positioned on the sleeve holder empty tube defined and fixed. The two acting on the empty tube probing lever and the two counter-clamping lever form in conjunction with the sleeve holder of the tube gripper two spaced-apart 3-point clamping devices that align the empty tube both in accordance with regulations, as well as secure.

In vorteilhafter Ausführungsform sind die Gegenspannhebel jeweils durch ein Federelement so beaufschlagbar, dass ihre Kurvenkontur stets am Gleit- und Führungselement des Antasthebels anliegt.In an advantageous embodiment, the counter-clamping lever can each be acted upon by a spring element so that its curve contour always bears against the sliding and guide element of the probe lever.

Auf diese Weise wird sichergestellt, dass sich der Gegenspannhebel immer in einer durch den zugehörigen Antasthebel vorgegebenen Stellung befindet.In this way it is ensured that the counter-clamping lever is always in a predetermined position by the associated probing lever.

Um die Lage der Rotationsachse der aufgenommenen Leerhülse stets entsprechend ihres Hülsenformats, das, wie vorstehend bereits angedeutet, bekannt und in einem Speicher einer Steuereinrichtung des Kreuzspulenwechselaggregats hinterlegt ist, exakt einstellen zu können, ist das Gleit- und Führungselement des zweiten Antasthebels so ausgebildet und so definiert einstellbar, dass beim Schließen des Hülsengreifers die Rotationsachse einer Leerhülse automatisch in eine vorgegebene Lage geschoben wird.To the position of the axis of rotation of the recorded empty tube always according to their sleeve size, which, as already indicated above, known and stored in a memory of a control device of the cheese change unit, to be able to adjust exactly, the sliding and guide element of the second probe lever is designed and so Defined adjustable that when closing the tube gripper, the rotation axis of an empty tube is automatically pushed into a predetermined position.

Das Gleit- und Führungselement ist vorzugsweise als exzentrisch gelagerter Einstellbolzen ausgebildet, der, durch einen elektromotorischen Antrieb beaufschlagbar, definiert in vorgebbaren Arbeitsstellungen positionierbar ist.The sliding and guiding element is preferably designed as an eccentrically mounted adjusting bolt, which, acted upon by an electric motor drive, defined in predeterminable working positions can be positioned.

Das heißt, über die Arbeitsstellung des am zweiten Antasthebel angeordneten Gleit- und Führungselements, das mit der Kurvenkontur des zugehörigen Gegenspannhebels korrespondiert, kann beim Einschwenken des Antasthebels die Mitte der zweiten 3-Punkt-Spanneinrichtung und damit die Lage der Rotationsachse der Leerhülse exakt eingestellt werden.That is, the center of the second 3-point clamping device and thus the position of the axis of rotation of the empty tube can be set exactly on the working position of the arranged on the second feeler sliding and guide member corresponding to the curve contour of the associated counter-clamping lever when swinging the probing lever ,

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

In der Figur 1 ist in Vorderansicht eine Kreuzspulen herstellende Textilmaschine, im Ausführungsbeispiel ein Kreuzspulautomat, dargestellt und insgesamt mit der Bezugszahl 1 gekennzeichnet.In the FIG. 1 is in front view of a cheese-producing textile machine, in the embodiment, a cheese winding machine, shown and designated overall by the reference numeral 1.

Derartige Kreuzspulautomaten 1 verfügen üblicherweise über eine Vielzahl identischer, zwischen Endgestellen 5 und 6 angeordneter Arbeitsstellen 2. Die Arbeitsstellen 2 sind dabei in einer Reihe nebeneinander angeordnet und bei Bedarf von einem vor der Textilmaschine 1 angeordneten Bediengang aus zugängig.Such spooling machines 1 usually have a plurality of identical, between end racks 5 and 6 arranged jobs 2. The jobs 2 are arranged side by side in a row and, if necessary, arranged by an arranged in front of the textile machine 1 operating gear from.

Auf diesen, vielfach auch als Spulstellen bezeichneten Arbeitsstellen 2 werden, wie bekannt und daher nicht näher erläutert, Spinnkopse 9 zu großvolumigen Kreuzspulen 11 umgespult. Die Spinnkopse 9 sind während des Umspulprozesses in Abspulstellungen 10 positioniert, die sich jeweils im Bereich (in Fig.1 nicht dargestellt) so genannter Quertransportstrecken 26 befinden.On these, often also referred to as winding stations 2 jobs, as known and therefore not explained in detail, spinning reels 9 rewound to large-volume cheeses 11. The spinning cops 9 are positioned during Abspulprozesses in Abspulstellungen 10, each in the area (in Fig.1 not shown) so-called transverse transport routes 26 are located.

Wie in den Figuren 1 und 2 angedeutet, erfolgt die Ver- und Entsorgung der Arbeitsstellen 2 mit Vorlagematerial über ein Spulen- und Hülsentransportsystem 3. In diesem Spulen- und Hülsentransportsystem 3, von dem in Figur 1 lediglich die Hülsenrückführstrecke 7 dargestellt ist, laufen, in vertikaler Ausrichtung auf Hülsentransporttellern 8 Spinnkopse 9 bzw. leere Kopshülsen 4 um.As in the FIGS. 1 and 2 indicated, the supply and disposal of jobs 2 with template material via a bobbin and tube transport system 3. In this bobbin and tube transport system 3, from the in FIG. 1 only the sleeve return path 7 is shown, run in a vertical orientation on Hülsentransporttellern 8 spinning cops 9 or empty Kop sleeves 4.

Da die Spinnkopse 9 nicht nur umgespult werden, sondern der Faden während des Umspulprozesses auch kontrolliert und bei Bedarf ausgereinigt wird, verfügt jede der Arbeitsstellen 2 über eine Anzahl spezieller Fadenüberwachungs- und -bearbeitungseinrichtungen, die an sich bekannt und nachfolgend im Zusammenhang mit der Fig.2 kurz erläutert sind.Since the spinning cops 9 are not only rewound, but the thread during the Umspulprozesses also controlled and at If necessary, each of the workplaces 2 has a number of special thread monitoring and processing devices known per se and subsequently in connection with the Fig.2 are briefly explained.

In der Fig.1 beschränkt sich die schematische Darstellung der einzelnen Arbeitsstellen 2 auf die Andeutung des Endproduktes, einer sogenannten Kreuzspule 11, einer Kreuzspulenantriebswalze 17 sowie eines oberhalb der Arbeitsstellen 2 verfahrbar angeordneten Kreuzspulenwechselaggregats 12, das mit seinem Fahrwerk 18A, 18B auf oberhalb der Arbeitsstellen 2 verlaufenden Laufschienen 21A, 21B gelagert ist.In the Fig.1 The schematic representation of the individual workstations 2 is limited to the intimation of the end product, a so-called cross-wound bobbin 11, a cross-wound bobbin drive roller 17 and a cross-bobbin change unit 12 movably arranged above the workstations 2, with its running gear 18A, 18B running rails 21A running above the workstations 2, 21B is stored.

Jede der Arbeitsstellen 2 verfügt über einen arbeitsstelleneigenen Leerhülsenspeicher 13 zur Aufnahme einer Anzahl von Leerhülsen 14, die zur Herstellung einer Kreuzspule 11 benötigt werden.Each of the work stations 2 has a working empty reel storage 13 for receiving a number of empty tubes 14, which are needed to produce a cross-wound bobbin 11.

Wie in Figur 1 des Weiteren angedeutet, verfügt jede Arbeitsstelle 2 außerdem über einen Arbeitsstellenrechner 15, der zum Beispiel über ein (nicht dargestelltes) Bussystem an einen Zentralinformator 16 der Textilmaschine angeschlossen ist.As in FIG. 1 further indicated, each workstation 2 also has a workstations computer 15, which is connected, for example via a (not shown) bus system to a central computer 16 of the textile machine.

Auch die Steuereinrichtung des Kreuzspulenwechselaggregats 12 ist über eine (nicht dargestellte) Busleitung mit dem Zentralinformator 16 der Textilmaschine 1 und damit auch mit den Arbeitsstellenrechnern 15 der einzelnen Arbeitsstellen 2 verbunden. Das heißt, zwischen den einzelnen Arbeitsstellen 2 und dem Kreuzspulenwechselaggregat 12 ist eine Kommunikation gegeben, was einen bedarfsgerechten Einsatz des Kreuzspulenwechselaggregats 12 ermöglicht.The control device of the cheese change unit 12 is connected via a (not shown) bus line to the central information processor 16 of the textile machine 1 and thus also to the workstation computers 15 of the individual work stations 2. That is, between the individual jobs 2 and the cheese change unit 12 is given a communication, which allows a needs-based use of the cheese change unit 12.

Wie in Fig. 1 angedeutet und in der Fig. 2 näher dargestellt, ist das Kreuzspulenwechselaggregat 12 mit Fahrwerken 18A, 18B verfahrbar auf maschinenlangen Laufbahnen 21A, 21B, die oberhalb der Arbeitsstellen 2 angeordnet sind, angeordnet. Das Kreuzspulenwechselaggregat 12 sorgt im Bedarfsfall dafür, dass, wenn auf einer Arbeitsstelle 2 eine Kreuzspulen 11 fertiggestellt ist, die Kreuzspule 11 aus dem Spulenrahmen 20 auf eine Kreuzspulentransporteinrichtung 19 überführt und in den Spulenrahmen 20 der betreffenden Arbeitsstelle 2 eine neue Leerhülse 14 eingewechselt wird. Die entsprechende Leerhülse 14 entnimmt das Kreuzspulenwechselaggregat 12 dabei mit seinem erfindungsgemäßen Hülsengreifer 31 einem arbeitsstelleneigenen Leerhülsenspeicher 13.As in Fig. 1 indicated and in the Fig. 2 shown in more detail, is the cheese change unit 12 with trolleys 18A, 18B movable on machine-length raceways 21A, 21B, which are arranged above the work stations 2, arranged. If necessary, the cross-coil changing unit 12 ensures that when a cross-wound bobbin 11 is completed on a workstation 2, the cross-wound bobbin 11 is transferred from the creel 20 to a cross-bobbin conveyor 19 and a new empty tube 14 is loaded into the creel 20 of the relevant workstation 2. The corresponding empty tube 14 removes the cheese change unit 12 with its sleeve gripper 31 according to the invention a working empty empties memory 13th

Die Fig. 2 zeigt eine Seitenansicht auf eine Arbeitsstelle 2 einer Kreuzspulen herstellenden Textilmaschine 1.The Fig. 2 shows a side view of a job 2 of a cheese-producing textile machine. 1

Wie vorstehend bereits angedeutet, verfügen derartige Textilmaschinen über ein relativ umfangreiches Spulen- und Hülsentransportsystem 3, von dem in Fig. 2 die maschinenlange Kopszuführstrecke 24, die reversierende Speicherstrecke 25, eine der zu den Spulstellen 2 führenden Quertransportstrecken 26 sowie die Hülsenrückführstrecke 7 dargestellt ist.As already indicated above, such textile machines have a relatively extensive bobbin and tube transport system 3, of which in Fig. 2 the machine-length Kopszuführstrecke 24, the reversing memory section 25, one of the leading to the winding units 2 transverse transport sections 26 and the sleeve return path 7 is shown.

In diesem Spulen- und Hülsentransportsystem 3 werden, wie vorstehend bereits angedeutet, in vertikaler Ausrichtung auf Transporttellern 8 stehend, Spinnkopse 9, die auf einer (nicht dargestellten) Ringspinnmaschine produziert wurden, sowie abgearbeitete Leerhülsen 4 befördert.In this coil and sleeve transport system 3, as already indicated above, standing in vertical alignment on transport plates 8, spinning cops 9, which were produced on a (not shown) ring spinning machine, as well as processed empty tubes 4 conveyed.

Die angelieferten Spinnkopse 9 werden in einer Abspulstellung 10 der Arbeitsstellen 2 zu großvolumigen Kreuzspulen 11 umgespult. Die einzelnen Arbeitsstellen verfügen zu diesem Zweck, wie an sich bekannt und daher nur angedeutet, über verschiedene Einrichtungen, die einen ordnungsgemäßen Betrieb der Arbeitsstellen 2 gewährleisten.The delivered spinning cops 9 are rewound in a pay-off position 10 of the jobs 2 to large-volume cheeses 11. For this purpose, the individual workplaces have, as is known and therefore only indicated, various facilities which ensure the proper functioning of the workplaces 2.

In Fig. 2 ist mit 30 der vom Spinnkops 9 zur Kreuzspule 11 laufende Faden, mit 32 eine Saugdüse, mit 33 ein Greiferrohr, mit 34 eine Fadenspleißeinrichtung, mit 35 eine Fadenspann einrichtung, mit 36 ein Fadenreiniger mit Fadenschneideinrichtung sowie mit 37 eine Paraffiniereinrichtung angedeutet. Die Spulenantriebstrommel, die die Kreuzspule 11 während des Spulvorganges über Reibschluss antreibt, trägt die Bezugszahl 17.In Fig. 2 is with 30 of the spinning cop 9 to the cheese 11 running thread, with 32 a suction nozzle, with 33 a gripper tube, with 34 a thread splicer, with 35 a thread tensioner device, with 36 a thread cleaner with thread trimmer and 37 indicated a paraffining device. The bobbin drive drum, which drives the cross-wound bobbin 11 by friction during the winding process, bears the reference numeral 17.

Während des Spulvorganges ist die Kreuzspule 11 in einem Spulenrahmen 20 gehalten, der um eine Achse 22 schwenkbar gelagert ist.During the winding process, the cheese 11 is held in a coil frame 20 which is pivotally mounted about an axis 22.

Hinter den Arbeitsstellen 2 verläuft eine Kreuzspulentransporteinrichtung 19, auf die die fertig gestellten Kreuzspulen 11 ausgetragen und anschließend zu einer maschinenendseitig angeordneten (nicht dargestellten) Verladestation befördert werden. Jede Arbeitsstelle verfügt über einen Leerhülsenspeicher 13, in dem Leerhülsen 14 zum Aufwickeln von Kreuzspulen 11 vorgehalten werden.Behind the workstations 2 runs a cross-coil transport device 19, on which the finished cross-wound bobbins 11 are discharged and subsequently conveyed to a machine-end-side (not shown) loading station. Each workstation has an empty tube storage 13, in which empty tubes 14 are held up for winding cheeses 11.

Wie vorstehend bereits erwähnt, werden die Arbeitsstellen 2 im Bedarfsfall durch ein Kreuzspulenwechselaggregat 12 versorgt. Das mit seinem Fahrwerk 18A, 18B auf maschinenlangen Laufschienen 21A, 21B entlang der Arbeitsstellen 2 verfahrbar angeordnete Kreuzspulenwechselaggregat 12 sorgt dafür, dass Kreuzspulen 11, die einen vorgegebenen Durchmesser erreicht haben, auf die Kreuzspulentransporteinrichtung 19 ausgetragen werden und dass anschließend aus dem Leerhülsenspeicher 13 eine neue Leerhülse 14 in den Spulenrahmen 20 der betreffenden Arbeitsstelle 2 eingewechselt wird.As already mentioned above, the jobs 2 are supplied by a cheese change unit 12 if necessary. The cross-bobbin changing unit 12, which is movably arranged with its running gear 18A, 18B on machine-length slide rails 21A, 21B along the workstations 2, ensures that cheeses 11 which have reached a predetermined diameter are discharged onto the cross-bobbin transport device 19 and subsequently from the empty tube store 13 Empty tube 14 is loaded in the creel 20 of the relevant job 2.

In Fig. 2 sind außerdem die während des Wechselvorganges Kreuzspule/Leerhülse vom Kreuzspulenwechselaggregat 12 benötigten Handhabungselemente dargestellt, die da sind: Rahmenöffner 23, Rahmenheber 28, Spulenführungsvorrichtung 29 sowie Hülsengreifer 31.In Fig. 2 In addition, the handling elements required during the changing process cross-wound bobbin / empty tube of the cross-bobbin changing unit 12 are shown, which are: frame opener 23, frame lifter 28, coil guide device 29 and tube gripper 31.

Der Übersichtlichkeit halber wurde auf eine Darstellung der weiteren Handhabungselemente derartiger Kreuzspulenwechsler verzichtet.For the sake of clarity, attention has been drawn to an illustration of the further handling elements of such cheese packages waived.

Die Vorrichtung zum Erstellen einer Kopfreservewicklung sowie die Vorrichtung zum Anlegen des Fadens 30 an die Leerhülse 14 sind beispielsweise nicht gezeigt.The device for creating a head reserve winding and the device for applying the thread 30 to the empty tube 14 are not shown, for example.

In Fig.3 ist der erfindungsgemäße Hülsengreifer 31 des Kreuzspulenwechselaggregats 12 in perspektivischer Seitenansicht dargestellt.In Figure 3 the tube gripper 31 of the cheese change unit 12 according to the invention is shown in a perspective side view.

Wie ersichtlich, ist das tragende Bauteil des Hülsengreifers 31 ein Zentralträger 42, an dem endseitig stationär ein Hülsenhalter 27 festgelegt ist und an den über eine erste Achse 41 die Antasthebel 39A und 39B sowie über eine zweite Achse 47 die Gegenspannhebel 40A und 40B angeschlossen sind.As can be seen, the supporting member of the tube gripper 31 is a central support 42, at the end stationary a sleeve holder 27 is fixed and to a first axis 41, the stop arms 39A and 39B and a second axis 47, the counter-clamping lever 40A and 40B are connected.

Der Zentralträger 42 bildet über eine weitere Achse 56 außerdem ein Widerlager für die Pneumatikzylinder 43A und 43B, die ihrerseits außerdem jeweils an einen der Antasthebel 39A bzw. 39B anschlossen sind.The central support 42 also forms, via a further axis 56, an abutment for the pneumatic cylinders 43A and 43B, which in turn are also respectively connected to one of the detent levers 39A and 39B.

Das bedeutet, wenn die Pneumatikzylinder 43A, 43B mit Druck beaufschlagt werden, schwenken die Antasthebel 39A, 39B in Richtung R nach unten und legen sich von oben auf eine (in Fig.3 nicht dargestellte) Leerhülse 14.That is, when the pneumatic cylinders 43A, 43B are pressurized, the probing levers 39A, 39B pivot down in the direction R and lay from above on a (in Figure 3 not shown) empty sleeve 14th

Die Antasthebel 39A bzw. 39B sind jeweils mit einem Gleit- und Führungselement 44A bzw. 44B ausgestattet, das mit einer Kurvenkontur 55A bzw. 55B eines zugehörigen Gegenspannhebel 40A bzw. 40B korrespondiert, mit der Folge, dass gleichzeitig auch die Gegenspannhebel 40A bzw. 40B eingeschwenkt werden und mit den Antasthebeln 39A, 39B sowie dem Hülsenhalter 27 zwei beabstandet angeordnete 3-Punkt-Spanneinrichtungen 38A und 38B bilden.The detent levers 39A and 39B are each provided with a sliding and guiding element 44A and 44B corresponding to a cam contour 55A and 55B, respectively, of an associated counter-tensioning lever 40A and 40B, with the result that at the same time the counter-tensioning levers 40A and 40B respectively be pivoted and with the probe arms 39A, 39B and the sleeve holder 27 two spaced apart 3-point clamping devices 38A and 38B form.

Die Gleit- und Führungselemente 44A und 44B unterscheiden sich dabei, wie nachfolgend anhand der Fig.5 näher erläutert werden wird, in einem wesentlich Punkt voneinander, nämlich, dass die Lage des am Antasthebel 39B installierten Gleit- und Führungs elementes 44b bezüglich seiner Arbeitsstellung definiert einstellbar ist.The sliding and guide elements 44A and 44B differ, as described below with reference to Figure 5 will be explained in more detail, in a significant point from each other, namely, that the location of the sliding lever and guide installed on the detent 39B element 44b defined with respect to its working position is adjustable.

Der Zentralträger 42 ist über Parallelogrammlenker 50, 51 mit einem Dreharm 52 verbunden, der seinerseits, wie insbesondere aus der Fig.4 ersichtlich, über eine Schwenkwelle 53 an einen elektromotorischen Schwenkantrieb 54 des Hülsengreifers 31 angeschlossen ist.The central support 42 is connected via parallelogram 50, 51 with a rotary arm 52, which in turn, in particular from the Figure 4 can be seen, connected via a pivot shaft 53 to an electromotive pivot drive 54 of the tube gripper 31.

Wie aus Fig.4 weiter ersichtlich, ist der Parallelogrammlenker 51 über einen Stellhebel 59 außerdem indirekt an einen Stellantrieb 60 angeschlossen.How out Figure 4 Furthermore, the parallelogram link 51 is also indirectly connected to an actuator 60 via a control lever 59.

Die Fig.5 zeigt eine Prinzipskizze des an den Antasthebel 39B angeschlossenen Gleit- und Führungselements 44B.The Figure 5 shows a schematic diagram of the sliding and guide element 44 B connected to the detent lever 39 B.

Wie ersichtlich, ist am Antasthebel 39B mittels Schraubenbolzen 58 oder dgl. ein Befestigungsblech 57 festgelegt, das einen definiert ansteuerbaren E-Motor 46, vorzugsweise einen Schrittmotor, trägt.As can be seen, a mounting plate 57 is fixed to the stop lever 39B by means of bolts 58 or the like, which carries a defined controllable electric motor 46, preferably a stepper motor.

Auf der Motorwelle 61 dieses Schrittmotors ist ein exzentrisch ausgebildetes Gleit- und Führungselement 44B befestigt, an dem, durch ein Federelement 45 beaufschlagt, die Kurvenkontur 55 des Gegenspannhebels 40B anliegt.On the motor shaft 61 of this stepping motor, an eccentrically formed sliding and guide element 44 B is fixed to which, acted upon by a spring element 45, the cam contour 55 of the counter-clamping lever 40 B is applied.

Bei Druckbeaufschlagung des Pneumatikzylinders 43 B schwenkt der Antasthebel 39B in Richtung R nach unten und legt sich auf die im Hülsenhalter 27 vorpositionierte Leerhülse 14. Gleichzeitig sorgt der Antasthebel 39B über das Gleit- und Führungselement 44B, das an der Kurvenkontur 55 des Gegenspannhebel 40B entlanggleitet, dafür, dass der Gegenspannhebel 40B um die Achse 47 nach oben geschwenkt wird.When the pneumatic cylinder 43 B is pressurized, the probing lever 39B pivots downward in the direction R and lies down on the empty tube 14 prepositioned in the sleeve holder 27. At the same time the probing lever 39B provides the sliding and guiding element 44B, which slides along the curve contour 55 of the counter-clamping lever 40B, that the counter-clamping lever 40B is pivoted about the axis 47 upwards.

Der einschwenkende Antasthebel 39B und der einschwenkende Gegenspannhebel 40B bilden dabei in Verbindung mit dem Hülsenhalter 27 die zweite 3-Punkt-Spanneinrichtung 38B.The einschwenkende probing lever 39B and the einschwenkende counter-tensioning lever 40B form in conjunction with the sleeve holder 27, the second 3-point clamping device 38B.

Die exakte Lage dieser 3-Punktspanneinrichtung 38B und damit die Lage der Rotationsachse 62 der aufgenommenen Leerhülse 14 ist durch Einstellen der Winkellage des Gleit- und Führungselements 44B exakt vorgebbar.The exact position of this 3-point clamping device 38B and thus the position of the axis of rotation 62 of the recorded empty tube 14 can be exactly predetermined by adjusting the angular position of the sliding and guide element 44B.

Das Gleit- und Führungselements 44B ist, wie in Fig.5 dargestellt, vorzugsweise als ein auf einer Rotationsachse 48 gelagerter, exzentrisch ausgebildeter Stellbolzen gestaltet.The sliding and guiding element 44B is, as in FIG Figure 5 illustrated, preferably designed as a mounted on a rotation axis 48, eccentrically formed adjusting bolt.

Die Arbeitsweise des erfindungsgemäßen, an einem Kreuzspulenwechselaggregat angeordneten Hülsengreifers:

  • Wie beispielsweise in der nachveröffentlichten DE 10 2010 035 068.0 relativ ausführlich beschrieben, sind die Textilmaschinen, an denen Kreuzspulenwechselaggregate mit erfindungsgemäß ausgebildeten Hülsengreifer zum Einsatz kommen, mit Eingabe- und Steuerungsmittel zur Bestimmung der jeweils vom Format der einzuwechselnden Leerhülsen abhängigen Parameter und zum entsprechenden, definierten Ansteuern zugehöriger Antriebe der Arbeitsstellen bzw. des Kreuzspulenwechselaggregats ausgestattet. Das heißt, an den Arbeitsstellen der Textilmaschine und/oder dem Kreuzspulenwechselaggregat sind Eingabevorrichtungen vorhanden, die es dem Bedienpersonal ermöglichen, die Antriebe der Spulvorrichtungen der Arbeitsstellen sowie die Antriebe der Handhabungseinrichtungen des Kreuzspulenwechselaggregats in Abhängigkeit vom Hülsenformat der einzuwechselnden Leerhülse manuell so zu verfahren, dass die Spulenrahmen der Arbeitsstellen und der Hülsengreifer des Kreuzspulenwechselaggregats in den Hülsenübergabestellungen jeweils exakt in dem Hülsenformat entsprechenden Stellungen positioniert sind.
The mode of operation of the tube gripper according to the invention arranged on a cross-wound bobbin changing unit:
  • For example, in the post-published DE 10 2010 035 068.0 described in relative detail, the textile machines, on which cross-bobbin changing units are inventively designed with tube gripper used with input and control means for determining the respective dependent on the format of the empty tubes to be inserted parameters and the corresponding, defined driving associated drives the workstations and the cheese change unit equipped , That is, at the workstations of the textile machine and / or the cheese change unit input devices are available that allow the operator to manually drive the winder of the winder of jobs and the drives of handling devices of the cheese change unit depending on the sleeve size of the empty tube to be inserted so that the Coil frames of the jobs and the tube gripper of the cheese change unit in the sleeve transfer positions are each positioned exactly in the sleeve format corresponding positions.

Des Weiteren sind Speichereinrichtungen vorhanden, in denen insbesondere die manuell verfahrenen Wege des Hülsengreifers gespeichert werden, die später von der Steuereinrichtung des Kreuzspulenwechselaggregats beim Einlegen der Leerhülse in den Spulenrahmen einer Arbeitsstelle zum selbsttätigen, exakten Positionieren der Leerhülse benutzt werden. Der Bediener wird bei der Bestimmung der zur exakten Positionierung des Hülsengreifers notwendigen Parameter erheblich unterstützt, da er lediglich die Antriebe manuell ansteuern und in die von dem jeweiligen Hülsenformat abhängigen Positionen fahren muss.Furthermore, storage devices are provided in which in particular the manually traversed paths of the tube gripper are stored, which later by the control device of the cheese change unit when inserting the empty tube in the creel of a job for automatic, exact Positioning the empty tube can be used. The operator is considerably assisted in determining the parameters necessary for the exact positioning of the tube gripper, since he only has to manually control the drives and move into the positions dependent on the respective sleeve format.

Es ist nicht erforderlich, dass irgendwelche Parameter numerisch von dem Bediener ermittelt werden. Die Parameter werden vielmehr von der Steuerung der Textilmaschine bzw. des Kreuzspulenwechselaggregats selbsttätig erfasst, da die manuell verfahrenen Wege gespeichert werden, was später eine einfache Anpassung des Hülsengreifers an unterschiedliche Hülsenformate ermöglicht.It is not necessary that any parameters be numerically determined by the operator. Rather, the parameters are automatically detected by the control of the textile machine or the cheese change unit, since the manually moved paths are stored, which later allows a simple adjustment of the tube gripper to different sleeve formats.

Wenn später während des Spulprozesses an einer der Arbeitsstellen 2 des Kreuzspulautomaten 1 eine Kreuzspule 11 ihre vorgegebene Größe (= vorgegebener Durchmesser oder vorgegebene Fadenlänge) erreicht hat, was durch den Arbeitsstellenrechner 15 der Arbeitsstelle 2 erfasst wird, wird das Kreuzspulenwechselaggregat 12 zu der betreffenden Arbeitstelle 2 beordert und die Arbeitstelle 2 gestoppt.If later during the winding process at one of the jobs 2 of the automatic winder 1 a cheese 11 has reached its predetermined size (= predetermined diameter or thread length), which is detected by the workstation 15 of the job 2, the cheese change unit 12 to the relevant workstation. 2 ordered and the workstation 2 stopped.

Selbstverständlich kann das Kreuzspulenwechselaggregat 12 vom Arbeitsstellenrechner 15 der Arbeitsstelle 2 auch bereits kurz vor Fertigstellung der Kreuzspule 11 zu der betreffenden Arbeitsstelle 2 gerufen werden.Of course, the cheese change unit 12 from the workstation 15 of the job 2 also be called shortly before completion of the cheese 11 to the relevant job 2.

Das an die Arbeitstelle 2 gerufene Kreuzspulenwechselaggregat 12 positioniert sich an der betreffenden Arbeitstelle 2 und ergreift mit einer entsprechenden Fadenhandhabungsvorrichtung den vom Spinnkops 9 zur Kreuzspule 11 laufenden Faden.The cross-coil changing unit 12 called to the workstation 2 positions itself at the relevant workstation 2 and grips with a corresponding thread-handling device the thread running from the spinning cop 9 to the cheese 11.

Der gefasste Faden wird gekappt, wobei das mit der Vorlagespule 9 verbundene Fadenende, wie bekannt, zur Erstellung einer neuen Kreuzspule 11 bereitgehalten wird.The collected thread is cut, with the thread end connected to the supply spool 9, as is known, for preparing a new cross-wound bobbin 11 is kept ready.

Nahezu gleichzeitig wird der Spulenrahmen 20 der Arbeitsstelle 2 durch den Rahmenheber 28 des Kreuzspulenwechselaggregats 12 aus seiner Spulposition in eine Spulenabgabeposition verschwenkt, durch den Rahmenöffner 23 geöffnet und die fertiggestellte Kreuzspule 11 durch die Spulenführungseinrichtung 29 sicher auf eine hinter den Arbeitstellen 2 verlaufende, maschinenlange Kreuzspulen-Transporteinrichtung 19 übergeben.Almost simultaneously, the creel 20 of the job 2 is pivoted by the frame lifter 28 of the cheese change unit 12 from its winding position in a Spulenabgabeposition, opened by the Rahmenöffner 23 and the finished cheese 11 by the bobbin guide device 29 safely on a running behind the workstations 2, machine-length cross-coil Transfer device 19 passed.

Anschließend wird der Spulenrahmen 20 in einer Hülsenübernahmestellung positioniert, die, wie vorstehend erläutert, jeweils durch das Hülsenformat, das auf der betreffenden Arbeitsstelle zum Einsatz kommt, vorgegeben ist.Subsequently, the bobbin frame 20 is positioned in a sleeve take-up position, which, as explained above, in each case by the sleeve format, which is used on the relevant workstation, is specified.

Während der Überführung der fertiggestellten Kreuzspule 11 an die Kreuzspulen-Transporteinrichtung 19 wird außerdem der Hülsengreifer 31 des Kreuzspulenwechselaggregats 12, durch die Antriebe 54 und 60 entsprechend angesteuert, zur Aufnahme einer neuen Leerhülse 14 zum arbeitsstelleneigenen Leerhülsenspeicher 13 geschwenkt und dabei das Gleit- und Führungselement 44B des Antasthebels 39B entsprechend des zu handhabenden Hülsenformats eingestellt. Der Hülsengreifer 31 wird dann mit seinem Hülsenhalter 27 unterhalb der vordersten der im Leerhülsenspeicher 13 bevorrateten Leerhülsen 13 positioniert.During the transfer of the finished cheese 11 to the cheese-transporting device 19 also the tube gripper 31 of the cheese change unit 12, driven by the drives 54 and 60 according to pivoted to receive a new empty tube 14 to the working empty emptying hopper 13 and thereby the sliding and guiding element 44B of the detent lever 39B is set according to the sleeve format to be handled. The tube gripper 31 is then positioned with its sleeve holder 27 below the foremost of the empty tubes 13 stored in the empty tube storage 13.

Anschließend werden durch Druckbeaufschlagungen der Pneumatikzylinder 43A, 43B die Antasthebel 39A, 39B in Richtung R auf die Leerhülse 13 hin abgesenkt.Subsequently, by pressing the pneumatic cylinder 43A, 43B, the probing levers 39A, 39B are lowered toward the empty tube 13 in the direction R.

Da die Antasthebel 39A, 39B über die Gleit- und Führungselemente 44A, 44B sowie die Kurvenkonturen 55 funktionell mit den Gegenspannhebeln 40A, 40B verbunden sind, schwenken gleichzeitig die Gegenspannhebel 40A, 40B in Richtung der Leerhülse 13 nach oben. Das heißt, der Hülsenhalter 27 bildet gemeinsam mit den Antasthebeln 39A, 39B und den Gegenspannhebeln 40A, 40B auf der Leerhülse 13 zwei beabstandet angeordnete 3-Punkt-Spanneinrichtungen 38A, 38B.Since the probing levers 39A, 39B are functionally connected to the counter-clamping levers 40A, 40B via the sliding and guiding elements 44A, 44B and the cam contours 55, the counter-clamping levers 40A, 40B simultaneously pivot upward in the direction of the empty tube 13. That is, the sleeve holder 27 forms, together with the probing levers 39A, 39B and the counter-clamping levers 40A, 40B on the empty tube 13, two spaced-apart 3-point clamping devices 38A, 38B.

Da das Gleit- und Führungselement 44B, das für die exakte Lage der 3-Punkt-Spanneinrichtung 38B zuständig ist, bereits vor dem Greifen der Leerhülse 13 entsprechend des Hülsenformats, das an der betreffenden Arbeitsstelle 2 vorliegt, positioniert wurde, wird die gefasste Leerhülse 13 beim Schließen des Hülsengreifers 31 bezüglich ihrer Rotationsachse 62 automatisch ordnungsgemäß ausgerichtet.Since the sliding and guiding element 44B, which is responsible for the exact position of the 3-point clamping device 38B, has already been positioned before the gripping of the empty tube 13 corresponding to the sleeve format present at the relevant workstation 2, the enclosed empty tube 13 becomes when closing the tube gripper 31 with respect to its axis of rotation 62 automatically aligned properly.

Das heißt, die aufgenommene Leerhülse 13 ist in der Hülsenübergabestellung jeweils so ausgerichtet, dass die Rotationsachse 62 der im Hülsengreifer 31 gehaltenen Leerhülse 13 mit der Rotationsachse der Hülsenaufnahmeteller des Spulenrahmens 20 der betreffenden Arbeitsstelle 2 übereinstimmt.That is, the recorded empty tube 13 is aligned in the sleeve transfer position in each case so that the axis of rotation 62 of the held in the tube gripper 31 empty tube 13 coincides with the rotational axis of the sleeve receiving plate of the coil frame 20 of the relevant job 2.

Die Leerhülse 13 kann in dieser Stellung beim Schließen des Spulenrahmens 20 der Arbeitsstelle 2 problemlos durch die Hülsenaufnahmeteller übernommen werden. Gleichzeitig oder anschließend wird das in der Handhabungseinrichtung des Kreuzspulenwechselaggregats 12 bereitgehaltene, mit der Ablaufspule verbundene Fadenende an der Leerhülse 13 festgelegt.The empty tube 13 can be easily taken over by the sleeve receiving plate in this position when closing the creel 20 of the job 2. At the same time or subsequently, the yarn end, which is held ready in the handling device of the cross-bobbin changing unit 12 and connected to the delivery bobbin, is fastened to the empty tube 13.

Der Wechselzyklus ist damit beendet, die betreffende Arbeitsstelle 2 kann neu gestartet werden.The change cycle is thus finished, the relevant job 2 can be restarted.
