Description

Die Erfindung betrifft eine Spulvorrichtung für eine Arbeitsstelle einer Kreuzspulen herstellenden Textilmaschine mit einem Spulenrahmen zum Haltern einer Kreuzspule, deren Hülse im Spulbetrieb zwischen den Hülsenaufnahmen des Spulenrahmens eingespannt ist, Mitteln zum Changieren eines aufzuwickelnden Fadens sowie einer Antriebswalze, die die Kreuzspule über Reibschluss antreibt, wobei eine Hülsenaufnahme entgegen der Wirkung eines Belastungsmittels in eine Öffnungsstellung zum Einlegen einer neuen Hülse axial verlagerbar ist und der Spulenrahmen über Arretierungsmittel verfügt, die für die Beabstandung der Hülsenaufnahme von der Antriebswalze sorgen.The invention relates to a winding device for a job of a cheese-producing textile machine with a creel for holding a cross-wound bobbin, the sleeve is clamped in the winding operation between the sleeve receptacles of the creel, means for traversing a wound thread and a drive roller which drives the cheese over frictional engagement, wherein a sleeve receptacle against the action of a loading means in an open position for inserting a new sleeve is axially displaceable and the creel has locking means which provide for the spacing of the sleeve receptacle of the drive roller.

Kreuzspulen herstellende Textilmaschinen sind sowohl Spulmaschinen als auch Spinnmaschinen, wie zum Beispiel Offenend-Spinnmaschinen. Sie sind seit langem bekannt, in zahlreichen Schutzrechtsanmeldungen ausführlich beschrieben und bestehen in der Regel aus einer Vielzahl von in Reihe nebeneinander angeordneten, gleichartigen Arbeitsstellen.Textile machines producing cross-wound bobbins are both winding machines and spinning machines, such as open-end spinning machines. They have long been known, described in detail in numerous applications for protection rights and usually consist of a large number of similar workplaces arranged in series next to one another.

Auf den Arbeitsstellen eines Spulautomaten werden in der Regel Spinnkopse, die relativ wenig Garnmaterial aufweisen, zu großvolumigen Kreuzspulen umgespult, die auf im Produktionsprozess nachgeschalteten Textilmaschinen, beispielsweise Webmaschinen, benötigt werden.On the workstations of an automatic winder usually spinning cops, which have relatively little yarn material, rewound to large-volume cheeses, which are needed in downstream in the production process textile machines, such as looms.

Die Kreuzspule liegt auf der Antriebswalze auf und wird von dieser über Reibschluss mitgenommen. Ist die Antriebswalze als Nutenwalze ausgebildet, so übernimmt sie zudem die Führung des aufzuwickelnden Fadens. Wird als Antriebswalze hingegen eine Trommel ohne Nuten verwendet, wird die Fadenführung von einem separaten Fadenführer, zum Beispiel einem Fingerfadenführer, gewährleistet.The cross-wound bobbin rests on the drive roller and is carried along by this via frictional engagement. If the drive roller is designed as a grooved roller, it also takes over the guidance of the thread to be wound up. If, however, a drum without grooves used as a drive roller, the thread guide of a separate thread guide, for example a finger thread guide guaranteed.

Die einzelnen Arbeitsstellen der Offenend-Spinnmaschinen verfügen jeweils über eine Spinn- und eine Spulvorrichtung, an der das in einer Spinnkanne vorgelegte Faserband zu einem Garn versponnen und zu einer Kreuzspule aufgewickelt wird.The individual workstations of the open-end spinning machines each have a spinning and a winding device, at which the sliver presented in a sliver can be spun into a yarn and wound into a cross-wound bobbin.

Nach Entnahme der Kreuzspule wird die axial verschiebbare Hülsenaufnahme mittels eines Belastungsmittels bis zu ihrem Endanschlag verlagert. Die Hülsenaufnahmen beinhalten so genannte Hülsenaufnahmeteller, die rotierbar gelagert sind und entsprechend verschiedener Hülsenformate ausgewechselt werden. Der Spulenrahmen selbst senkt sich ohne Gegenmaßnahmen aufgrund seines Eigengewichtes, bis er mit der verlagerten Hülsenaufnahme auf der Antriebswalze aufliegt und insbesondere bei einem versehentlichen Start der Antriebswalze beschädigt werden kann.After removal of the cheese, the axially displaceable sleeve receptacle is displaced by means of a loading means to its end stop. The sleeve receptacles contain so-called sleeve receiving plates, which are rotatably mounted and are replaced according to different sleeve formats. The creel itself lowers without countermeasures due to its own weight until it rests with the displaced sleeve receptacle on the drive roller and can be damaged in particular in an accidental start of the drive roller.

Durch die EP 0 878 428 A2 wird ein Verfahren und eine Aufspulvorrichtung zum Aufspulen eines kontinuierlich anlaufenden Fadens zu einer Spule offenbart, bei welchem bzw. bei welcher beim Aufwickeln einer Spule eine im wesentlichen hysteresefreie Dämpfung der Ausweichbewegung des frei beweglichen Trägers erfolgt, so dass auch noch bei extrem niedrigen Aufwickelgeschwindigkeiten gewickelt werden kann. Um dies zu erreichen, ist an einem Spindelträger oder an beiden Spindelträgern ein Zapfen angeordnet. Der Zapfen greift in eine Klemmvorrichtung ein. In der Klemmvorrichtung erfolgt eine zyklische Klemmung des Zapfens. Sind beide Spindelträger mit einer Klemmvorrichtung verbunden, werden die Klemmvorrichtungen synchron aktiviert, d.h. die Klemmung und das Lösen der Träger erfolgt an beiden Spindelträgern zur gleichen Zeit. Auf diese Weise wird das Schwingen der Andrückwalze in radialer Richtung relativ zum Maschinengestell eingeschränkt, so dass letztendlich die Schwingungen an der Spulspindel reduziert werden.By the EP 0 878 428 A2 discloses a method and a winding device for winding a continuously starting yarn to a coil, in which or when winding a coil substantially hysteresis-free damping of the evasive movement of the freely movable carrier takes place, so that even at extremely low take-up speeds are wound can. To achieve this, a pin is arranged on a spindle carrier or on both spindle carriers. The pin engages in a clamping device. In the clamping device, a cyclical clamping of the pin. If both spindle carriers are connected to a clamping device, the clamping devices are activated synchronously, ie the clamping and the release of the carrier takes place on both spindle carriers at the same time. In this way, the oscillation of the pressure roller in the radial direction is restricted relative to the machine frame, so that ultimately the vibrations are reduced to the winding spindle.

In der Serviceanleitung des Autoconer X5 der Firma Oerlikon Schlafhorst in der Version V3.0 von 04.2012, wird die aktuelle Vorgehensweise zur Verhinderung der Beschädigung beschrieben. Um das Aufliegen der Hülsenaufnahme auf der Antriebswalze zu verhindern, gibt es zwei einstellbare Begrenzungselemente: eine Stellschraube, die das Absenken des gesamten Spulenrahmens begrenzt und einen Anlaufring, der den Hub der verschiebbaren Hülsenaufnahme einschränkt.The service instructions for the Autoconer X5 from Oerlikon Schlafhorst in version V3.0 from 04.2012 describe the current procedure for preventing damage. To prevent the sleeve receptacle from resting on the drive roller, there are two adjustable limiting elements: a set screw which limits the lowering of the entire creel and a stop ring which restricts the stroke of the displaceable sleeve receptacle.

Dazu müssen mit eingelegter Hülse zwei Schrauben gelöst werden, so dass die Hülse auf der Antriebswalze beziehungsweise auf dem Auflaufring aufliegt. Nachdem die Schrauben wieder fest gedreht wurden, muss eine Anschlagschraube so weit in den Spulenrahmen eingedreht und schließlich gekontert werden, dass bei abgesenktem Spulenrahmen die rechte Hülsenaufnahme nicht die Antriebswalze berührt. Um das Spiel zu überprüfen, muss bei Anlauf der Antriebswalze eine sichere Mitnahme der Hülse gewährleistet sein.For this purpose, two screws must be solved with inserted sleeve, so that the sleeve rests on the drive roller or on the casserole ring. After the screws have been tightened again, a stop screw must be screwed into the creel and then finally countered that with the creel lowered, the right sleeve receptacle does not touch the drive roller. To check the game, a safe entrainment of the sleeve must be ensured at startup of the drive roller.

Die Hülse wird dazu durch eine Lehre ersetzt, durch Lösen einer weiteren Schraube ein Anschlagblech anliegend zum Nocken des Spulenrahmenöffnerhebels gebracht und schließlich durch Festdrehen der Schraube arretiert. Der auf diese Weise eingestellte Abstand zwischen Anschlag und Nocken muss in einem Bereich von 0,5 mm bis 1,0 mm liegen.The sleeve is replaced by a gauge, brought by loosening a further screw a stop plate adjacent to the cam of the bobbin frame opener lever and finally locked by tightening the screw. The distance between stop and cam set in this way must be within a range of 0.5 mm to 1.0 mm.

Nachteilig bei dieser Vorgehensweise ist, dass beide Einstellungen von der Geometrie der vorgelegten Hülsen abhängig sind und demzufolge immer wieder neu durchgeführt werden müssen. Das bedeutet, bei jedem Wechsel des Hülsenformates müssen erneut diese Einstellungen ermittelt werden, um einerseits das Aufliegen der Hülsenaufnahme auf der Antriebswalze zu verhindern und andererseits den Hub der verschiebbaren Hülsenaufnahme zu beschränken. Zudem müssen diese Einstellungen aufgrund der geometrischen Anordnung sehr präzise vorgenommen werden und sind damit sehr zeitaufwendig; oftmals ist ein Nachstellen nötig.A disadvantage of this approach is that both settings are dependent on the geometry of the sleeves presented and therefore must be performed again and again. This means that with each change of the sleeve format, these settings must again be determined in order to prevent the one hand, the rest of the sleeve receiving the drive roller and on the other hand, the stroke of the displaceable sleeve receptacle restrict. In addition, these settings must be made very precisely due to the geometric arrangement and are therefore very time consuming; often an adjustment is necessary.

Diese Vorgehensweise wirkt sich nicht nur negativ auf die Produktivität der Spul- oder Spinnmaschinen aus, sondern birgt ebenso die Gefahr, dass durch eine ungenaue Einstellung die Antriebswalze respektive die Hülsenaufnahme beschädigt werden.This procedure not only has a negative effect on the productivity of the winding or spinning machines, but also harbors the risk that the drive roller or the sleeve receptacle are damaged by an inaccurate setting.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die Vermeidung des Kontakts von Teilen des leeren Spulenrahmens unabhängig vom jeweils verwendeten Hülsenformat zu gewährleisten. Dabei sollen nicht nur das Handling vereinfacht und somit letztlich die Produktivität der Spulprozesse gesteigert, sondern auch potentielle Fehlerquellen reduziert werden.Based on the aforementioned prior art, the present invention seeks to ensure the avoidance of the contact of parts of the empty creel regardless of the sleeve format used in each case. This not only simplifies handling and thus ultimately increases the productivity of the winding processes, but also reduces potential sources of error.

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

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Zur Lösung der Aufgabe ist gemäß Anspruch 1 vorgesehen, dass die Arretierungsmittel durch ein begrenzt bewegliches im Spulenrahmen angeordnetes Distanzstück, welches sich in seiner Arretierungsstellung auf einem fixen Teil der Arbeitsstelle abstützt und eine mit dem Distanzstück zusammenwirkende Klemmeinrichtung gebildet sind, wobei die Klemmeinrichtung so angeordnet und durch das Belastungsmittel beaufschlagt ist, dass sie das Distanzstück bei nicht eingelegter Hülse klemmt und dadurch in seiner momentanen Position fixiert. Dadurch wird bei fehlender Hülse der Spulenrahmen automatisch und unabhängig vom verwendeten Hülsenformat mittels des geklemmten Distanzstücks auf Abstand zur Antriebswalze gehalten, ohne dass hierfür zuvor Einstellungen an der Maschine durchzuführen sind. Das bedeutet, dass die Hülsenaufnahme nicht die Antriebswalze berühren kann, da das Distanzstück durch die Klemmeinrichtung arretiert wird und bei fehlender Hülse das Belastungsmittel so auf die Klemmeinrichtung wirkt, dass diese das Distanzstück arretiert.To solve the problem is provided according to claim 1, that the locking means by a limited movable arranged in the coil frame spacer, which is supported in its locking position on a fixed part of the work and a cooperating with the spacer clamping device, wherein the clamping means arranged and is acted upon by the loading means that it clamps the spacer with not inserted sleeve and thereby fixed in its current position. As a result, the creel is held automatically and independently of the sleeve format used by means of the clamped spacer at a distance to the drive roller in the absence of the sleeve, without previously settings on the machine must be carried out. That means, that the sleeve receptacle can not touch the drive roller, since the spacer is locked by the clamping device and in the absence of the sleeve, the loading means acts on the clamping device, that this locks the spacer.

Gemäß Anspruch 2 ist das Distanzstück beweglich im Grundkörper des Spulenrahmens gelagert, während die Klemmeinrichtung an einem im Grundkörper drehbar gelagerten Spulenrahmenöffnerhebel festgelegt ist, der mit der axial verlagerbaren und durch das Belastungsmittel beaufschlagten Hülsenaufnahme gekoppelt ist. Durch die im Grundkörper des Spulenrahmens bewegliche Lagerung des Distanzstücks und eine beim Öffnen des Spulenrahmens über den Spulenrahmenöffnerhebel erfolgende vorübergehende Freigabe des Distanzstücks durch die am Spulenrahmenöffnerhebel angeordnete Klemmeinrichtung wird die Beabstandung des Spulenrahmens zur Antriebswalze ohne jedwede manuelle Einstellung gewährleistet. Das heißt, die Klemmeinrichtung, die am Spulenrahmenöffnerhebel befestigt ist, erhält dann bei leerem Spulenrahmen und Freigabe des Spulenrahmenöffnerhebels ihre Klemmkraft auf das Distanzstück durch das Belastungsmittel der Hülsenaufnahme und arretiert das Distanzstück, so dass das Distanzstück den Spulenrahmen auf einen fixen Teil der Arbeitsstelle abstützt. Das Distanzstück ist so dimensioniert, dass auch bei der Verwendung des größten Hülsenaufnahmetellers der Abstand zwischen Antriebswalze und Hülsenaufnahme zur Beabstandung ausreicht. Damit entfällt die Notwendigkeit einer Justierung selbst bei extremen Hülsenformaten.According to claim 2, the spacer is movably mounted in the main body of the coil frame, while the clamping device is fixed to a rotatably mounted in the base body Spulenrahmenöffnerhebel, which is coupled to the axially displaceable and acted upon by the loading means sleeve receptacle. Due to the movable in the main body of the creel storage of the spacer and taking place when opening the creel over the Spulenrahmenöffnerhebel temporary release of the spacer by the Spulenrahmenöffnerhebel arranged clamping device, the spacing of the creel to the drive roller is ensured without any manual adjustment. That is, the clamping device, which is attached to the bobbin frame opener lever, then receives its clamping force on the spacer by the loading means of the sleeve receptacle with empty bobbin frame and release of the bobbin frame opener lever and locks the spacer so that the spacer supports the bobbin frame on a fixed part of the job. The spacer is dimensioned so that even with the use of the largest sleeve receiving plate, the distance between the drive roller and sleeve receptacle sufficient for spacing. This eliminates the need for adjustment even with extreme sleeve formats.

Wie in Anspruch 3 beschrieben, sind Distanzstück und Klemmeinrichtung vorteilhaft so angeordnet und ausgebildet, dass dadurch die Endstellung der verschiebbaren Hülsenaufnahme sich nicht mit der Antriebswalze schneidet. Das heißt, die Klemmeinrichtung begrenzt den maximalen Hub der Hülsenaufnahme, so dass der Weg der axial verlagerbaren Hülsenaufnahme beschränkt ist.As described in claim 3, spacer and clamping device are advantageously arranged and designed so that thereby does not intersect the end position of the displaceable sleeve receptacle with the drive roller. That is, the clamping device limits the maximum stroke of the sleeve receptacle, so that the path of the axially displaceable sleeve receptacle is limited.

Wie in Anspruch 4 dargelegt, besteht das Distanzstück aus einem Fallbolzen. Der Fallbolzen ist gleitend gelagert sowie axial beweglich angeordnet und gewährleistet dadurch ein einfaches Handling, ohne dass Einstellungen an dem Spulenrahmen vorgenommen werden müssen.As set forth in claim 4, the spacer consists of a drop bolt. The drop bolt is slidably mounted and axially movable, thereby ensuring easy handling, without adjustments to the creel must be made.

Gemäß einer Weiterbildung der erfindungsgemäßen Spulvorrichtung nach Anspruch 5 ist die Klemmeinrichtung durch ein Sperrblech gebildet. Solch ein Sperrblech kann fertigungstechnisch ohne großen Aufwand und in hohen Stückzahlen produziert werden.According to one embodiment of the winding device according to the invention according to claim 5, the clamping device is formed by a locking plate. Such a locking plate can be produced without great effort and in high quantities production technology.

Ferner wird gemäß Anspruch 6 dargestellt, dass das Belastungsmittel eine Feder ist. Eine Feder als Maschinenelement ist wartungsfrei und einfach zu konstruieren. Die durch die Federkraft wirkende Klemmkraft ist ausreichend, um den Spulenrahmen in seiner Position zu halten und ein Absenken auf die Antriebswalze zu verhindern. Statt einer Feder könnte die Klemmkraft beispielsweise auch elektromagnetisch erzeugt werden.Further, it is shown in claim 6 that the loading means is a spring. A spring as a machine element is maintenance-free and easy to construct. The clamping force acting by the spring force is sufficient to hold the bobbin frame in position and prevent it from lowering onto the drive roller. For example, instead of a spring, the clamping force could also be generated electromagnetically.

Gemäß der Weiterbildung nach den Ansprüchen 7, 8 und 9 der Erfindung, weist der Fallbolzen Anschlagmittel zur axialen Wegbegrenzung auf. Um ein Durchrutschen des Fallbolzens bei der Entnahme der Kreuzspule zu verhindern, ist der Fallbolzen oben durch einen O-Ring gesichert. Ein O-Ring ist aus flexiblem Material gefertigt und verursacht während des Betriebs kein zusätzliches Geräusch. Auf der in Einbaurichtung unten liegenden Seite ist der Fallbolzen durch eine Endkappe gesichert, so dass auch beispielsweise bei Umbauarbeiten am Spulenrahmen der Fallbolzen nicht versehentlich aus seiner Führung herausrutschen kann.According to the development according to claims 7, 8 and 9 of the invention, the dart bolt stop means for axial travel limitation. In order to prevent slippage of the drop bolt when removing the cross-wound bobbin, the dowel bolt is secured at the top by an O-ring. An O-ring is made of flexible material and does not cause additional noise during operation. On the side lying in the direction of installation below the dowel is secured by an end cap, so that even when, for example, when rebuilding work on the creel of the dinghy can not accidentally slip out of his leadership.

Entsprechend dem Anspruch 10 weist der Fallbolzen eine oder mehrere radiale Nuten auf. Durch die Vertiefungen wird zwischen dem Fallbolzen und dem Sperrblech ein Formschluss erzeugt, so dass der Spulenrahmen sicher in der beabstandeten Position gehalten werden kann. Dadurch wird vermieden, dass, selbst wenn zusätzlicher Druck auf den Spulenrahmen ausgeübt wird und sich der Spulenrahmen senkt, die Hülsenaufnahme nicht die Antriebswalze berührt.According to claim 10, the dart pin has one or more radial grooves. Through the recesses, a positive connection is generated between the dowel and the locking plate, so that the coil frame securely held in the spaced position can be. This avoids that, even if additional pressure is exerted on the creel and the creel lowers, the sleeve receptacle does not touch the drive roller.

Die Erfindung wird nachfolgend anhand der in den Zeichnungen dargestellten Ausführungsbeispiele näher erläutert.The invention will be explained in more detail with reference to the embodiments illustrated in the drawings.

Figur 1 und 2 zeigen eine schematische Ansicht eines Spulenrahmens 1 einer Spulvorrichtung. In einer derartigen Spulvorrichtung wird ein Faden zu einer Kreuzspule 2 aufgewickelt. Die Kreuzspule 2 ist während des Spinn- respektive Spulprozesses mit ihrer Hülse 2' in einem Spulenrahmen 1 gehalten und wird dabei über eine Spulenantriebswalze 8, hier beispielsweise eine Fadenführungstrommel, mittels Reibschluss angetrieben. Die Fadenführungstrommel 8 sorgt neben dem Antrieb dafür, dass der Faden in sich kreuzenden Lagen auf die Kreuzspule 2 aufgespult wird. Der Spulenrahmen 1 ist um eine Schwenkachse 6 verschwenkbar gelagert. FIG. 1 and 2 show a schematic view of a coil frame 1 of a winding device. In such a winding device, a thread is wound into a cross-wound bobbin 2. The cross-wound bobbin 2 is held with its sleeve 2 'in a creel 1 during the spinning or winding process and is thereby driven via a bobbin drive roller 8, here for example a thread guide drum, by means of frictional engagement. The yarn guide drum 8 ensures, in addition to the drive, that the yarn is wound onto the cheese 2 in intersecting layers. The coil frame 1 is mounted pivotably about a pivot axis 6.

Des Weiteren verfügen derartige Spulenrahmen 1 insgesamt über Hülsenaufnahmen 3 mit Hülsenaufnahmetellern 4, zwischen denen die Hülse 2' eingespannt wird. Mittels des Spulenrahmenöffnerhebels 5 kann die in Vorderansicht rechte Hülsenaufnahme 3 axial verschoben werden, so dass die Hülse 2' der Kreuzspule 2 eingelegt werden kann.Furthermore, such creel 1 have a total of sleeve receptacles 3 with sleeve receiving plates 4, between which the sleeve 2 'is clamped. By means of the cork frame opener lever 5, the right sleeve receptacle 3 in front view can be moved axially, so that the sleeve 2 'of the cross-wound bobbin 2 can be inserted.

Die Figuren 3 und 4 zeigen Detailansichten der erfindungsgemäßen Vorrichtung, wobei keine Kreuzspule 2 oder Hülse 2' eingelegt ist. In einem Arm des Spulenrahmens 1 ist ein als Distanzstück wirkender Fallbolzen 9 gleitend gelagert und längs seiner Achse frei beweglich. Ein als Klemmeinrichtung wirkendes Sperrblech 13 liegt auf dem Arm des Spulenrahmens 1 an dem Fallbolzen 9 an. Mittels einer Spannfeder 14 wird eine Klemmkraft erzeugt, die auf den Spulenrahmenöffnerhebel 5 übertragen wird. Der Fallbolzen 9 wird in Einbaulage oben durch einen O-Ring 10 axial so gesichert, dass er ohne Wirkung des Sperrblechs in seiner Vertikalbewegung begrenzt wird. In Einbaurichtung unten wird dies durch eine Endkappe 11 gewährleistet. Eine oder mehrere Nuten 12 gewährleisten eine zusätzliche, formschlüssige Halterung des Fallbolzens 9 in dem Sperrblech 13.The Figures 3 and 4 show detailed views of the device according to the invention, wherein no cheese 2 or sleeve 2 'is inserted. In one arm of the coil frame 1 acting as a spacer dart pin 9 is slidably mounted and freely movable along its axis. An acting as a clamping device locking plate 13 rests on the arm of the coil frame 1 on the drop bolt 9. By means of a tension spring 14, a clamping force is generated which is transmitted to the bobbin frame opener lever 5. The drop bolt 9 is axially secured in the installed position above by an O-ring 10 so that it is limited in its vertical movement without the effect of the locking plate. In the installation direction below, this is ensured by an end cap 11. One or more grooves 12 ensure an additional, positive retention of the latch bolt 9 in the locking plate 13th

Figur 5 zeigt die Lagerung des Fallbolzens 9 im Grundkörper des Spulenrahmens 1. FIG. 5 shows the storage of the latch bolt 9 in the main body of the coil frame first

Durch Betätigen des Spulenrahmenöffnerhebels 5 nach rechts gegen die Kraft der Spannfeder 14 kann die Kreuzspule 2 aus dem Spulenrahmen 1 entnommen werden. Der Fallbolzen 9 fällt bis zum O-Ring 10 nach unten durch und liegt auf dem Spulstellengehäuse 7 auf. Anschließend rückt die verschiebbare Hülsenaufnahme 3 unter Wirkung der Spannfeder nach links und wird durch das Sperrblech 13 radial geklemmt. Die Klemmkraft wird ausgehend von der Spannfeder 14 der Hülsenaufnahme 3 über das Gelenk 15 auf den Spulenrahmenöffnerhebel 5, an dem das Sperrblech 13 befestigt ist, übertragen. Die Federkraft und die Hebelverhältnisse sind dabei so bemessen, dass die auf den Fallbolzen 9 wirkende Klemmkraft ausreichend ist, um den Fallbolzen 9 und damit den Spulenrahmen 1 in seiner Position zu halten und das Absenken auf die Fadenführungstrommel 8 zu verhindern. Gleichzeitig begrenzt das am Fallbolzen 9 anliegende Sperrblech 13 den maximalen Hub der verschiebbaren Hülsenaufnahme 3. Falls auf den beabstandeten Spulenrahmen 1 Druck ausgeübt wird, wird der Fallbolzen durch die radiale Nut 12 im Fallbolzen 9 abgefangen und ein Formschluss mit dem Sperrblech 13 erzeugt, so dass die Nut 12 die Beabstandung zusätzlich sichert.By pressing the bobbin frame opener lever 5 to the right against the force of the tension spring 14, the cross-wound bobbin 2 can be removed from the creel 1. The drop bolt 9 drops down to the O-ring 10 and lies on the winding unit housing 7. Subsequently, the displaceable sleeve receptacle 3 moves under the action of the tension spring to the left and is clamped radially by the locking plate 13. The clamping force is transmitted from the tension spring 14 of the sleeve receptacle 3 via the joint 15 on the bobbin frame opener lever 5, on which the locking plate 13 is attached. The spring force and the lever ratios are dimensioned such that the clamping force acting on the drop bolt 9 is sufficient to hold the drop bolt 9 and thus the creel 1 in its position and to prevent the lowering of the thread guide drum 8. At the same time limits the voltage applied to the drop bolt 9 locking plate 13, the maximum stroke of the displaceable sleeve receptacle 3. If pressure is exerted on the spaced coil frame 1, the dowel is intercepted by the radial groove 12 in the drop bolt 9 and produces a positive connection with the locking plate 13, so that the groove 12 additionally secures the spacing.

Wird eine neue Hülse 2' in den Spulenrahmen 1 eingelegt, so rückt die verschiebbare Hülsenaufnahme 3 längs ihrer Achse weiter nach rechts, die Spannfeder 14 klemmt die Hülse 2' und das Sperrblech 13 gibt den Fallbolzen 9 frei. Der Fallbolzen 9 ist nun wieder axial beweglich und der Spulenrahmen 1 respektive die Hülse 2' kann zur Auflage auf die Fadenführungstrommel 8 gebracht werden, ohne dass der Fallbolzen den erforderlichen Schwenkweg begrenzt. Der Spulenrahmen wird in Spulstellung ausschließlich durch die Hülse 2' respektive Kreuzspule 2 abgestützt, so dass sich ein exakter Reibschluss automatisch einstellt.If a new sleeve 2 'is inserted into the creel 1, then the displaceable sleeve receptacle 3 moves further along its axis to the right, the tension spring 14 clamps the sleeve 2' and the blocking plate 13 releases the drop bolt 9. The drop bolt 9 is now again axially movable and the coil frame 1 and the sleeve 2 'can be brought to rest on the yarn guide drum 8, without the dowel limited the required pivoting. The creel becomes exclusive in winding position supported by the sleeve 2 'and cross-wound bobbin 2, so that automatically adjusts an exact frictional engagement.

Daraus lässt sich erkennen, dass unabhängig vom Spulenformat sowohl ein sicherer Abstand der Hülsenaufnahmeteller von der Antriebswalze bei leerem Spulenrahmen 1 als auch ein für das Spulenformat optimaler Reibschluss zwischen Hülse 2' respektive Kreuzspule 2 und Antriebswalze gegeben ist.It can be seen that regardless of the coil format both a safe distance of the sleeve receiving plate is given by the drive roller with empty creel 1 and an optimum for the coil format frictional engagement between the sleeve 2 'respectively cross-wound bobbin 2 and drive roller.
