Description

Die Erfindung betrifft eine Vorrichtung zur Handhabung von Sleeves für Zylinder von Druckmaschinen.The invention relates to a device for handling sleeves for cylinders of printing machines.

Druckmaschinen weisen üblicherweise eine Vielzahl von Zylindern, beispielsweise Druckzylindern, Auftragwalzen und dergleichen auf, die gelegentlich, etwa bei einer Umrüstung der Druckmaschine auf einen anderen Druckauftrag, ausgewechselt werden müssen. Es sind Wechselsysteme bekannt, bei denen die Zylinder in der Druckmaschine hydraulisch oder pneumatisch auf eine Achse aufgespannt werden, die auch während eines Zylinderwechsels einseitig in der Druckmaschine gelagert bleibt, so daß sich die Zylinder axial abziehen auf aufschieben lassen. In diesem Fall weisen die Zylinder einen durchgehenden koaxialen Kanal auf, der von der maschinenfesten Achse durchsetzt wird, wenn die Zylinder in der Druckmaschine installiert sind. Dieser durchgehende Kanal läßt sich dann auch zur Handhabung der Zylinder außerhalb der Druckmaschine nutzen, indem das gesamte Logistiksystem für die Vorbereitung, Lagerung, den Transport und den Einbau der Zylinder mit Haltern ausgerüstet wird, die jeweils einen im wesentlichen waagerechten, frei auskragenden Dorn aufweisen, auf den sich die Zylinder aufstecken lassen.Printing presses usually have a plurality of cylinders, for example Printing cylinders, applicator rollers and the like, which occasionally, such as at a conversion of the printing press to another print job, replaced Need to become. There are known alternating systems in which the cylinders in the printing machine hydraulically or pneumatically clamped on an axis which are also one-sided in the printing press during a cylinder change stored, so that the cylinders pull off axially postpone to let. In this case, the cylinders have a continuous coaxial Channel interspersed by the machine-fixed axis when the cylinder are installed in the printing press. This continuous channel can be then also use to handle the cylinder outside the printing press, by the whole logistics system for the preparation, storage, transport and the installation of the cylinders is equipped with holders, each one have substantially horizontal, cantilevered spine, on the the cylinders can be attached.

Andererseits sind sogenannte Sleeve-Systeme bekannt, bei denen jeder Zylinder aus einem Kern und einer lösbar auf den Kern aufgeschobenen Hülse, dem sogenannten Sleeve, besteht. Bei der Umrüstung der Druckmaschine braucht dann nicht der gesamte Zylinder ausgewechselt zu werden, sondern es wird lediglich das Sleeve abgezogen und durch ein anderes Sleeve ersetzt, während der Zylinderkern in der Druckmaschine verbleibt. Die Sleeves sind zumeist relativ dünnwandig und haben jedenfalls einen verhältnismäßig großen Innenquerschnitt, der dem Außenquerschnitt des Zylinderkerns entspricht und deutlich größer ist als der Innenquerschnitt des Kanals bei den eingangs erwähnten Druckzylindern. Das Abziehen der Sleeves vom Zylinderkern und das Aufschieben derselben auf den Zylinderkern erfolgt bisher zumeist von Hand. In EP-A-1 090 754 wird jedoch eine in der Druckmaschine eingebaute Vorrichtung beschrieben, mit der das Abziehen des Sleeves vom Zylinderkern und das Aufschieben auf den Zylinderkern teilweise automatisiert werden kann. On the other hand, so-called sleeve systems are known in which each cylinder from a core and a detachable on the core pushed sleeve, the so-called Sleeve, persists. When converting the printing press needs then not the entire cylinder to be replaced, but it will only pulled off the sleeve and replaced with another sleeve, while the Cylinder core remains in the printing press. The sleeves are mostly relative thin-walled and in any case have a relatively large internal cross section, which corresponds to the outer cross section of the cylinder core and clearly larger than the inner cross section of the channel at the above-mentioned Pressure cylinders. The removal of the sleeves from the cylinder core and pushing the same on the cylinder core is done so far mostly by hand. In EP-A-1 However, 090 754 describes a device installed in the printing press, with the peeling of the sleeve from the cylinder core and sliding can be partially automated on the cylinder core.

Aufgabe der Erfindung ist es, eine Vorrichtung zu schaffen, die die Handhabung des Sleeves außerhalb der Druckmaschine erleichtert.The object of the invention is to provide a device that handling the sleeve is facilitated outside the printing press.

Diese Aufgabe wird erfindungsgemäß gelöst durch ein Tragrohr, auf dem eine in das Sleeve eingreifende Spanneinrichtung zum Einspannen des Sleeves in einer koaxial zum Tragrohr ausgerichteten Position angeordnet ist.This object is achieved by a support tube on which a in the sleeve engaging clamping device for clamping the sleeve in one Coaxially aligned with the support tube position is arranged.

Durch die Spanneinrichtung wird das Sleeve so mit dem Tragrohr verbunden, daß sich das Tragrohr koaxial durch das Sleeve erstreckt. Folglich kann das Sleeve dann am Tragrohr gehalten und transportiert werden, ohne daß das relativ dünnwandige Sleeve Verformungskräften ausgesetzt wird, die zu einer Beschädigung des Sleeves führen könnten. Insgesamt entspricht die Konfiguration aus Sleeve und Handhabungsvorrichtung dann einem kompletten Zylinder mit durchgehendem koaxialen Kanal der eingangs beschriebenen Art, wobei der Kanal durch den Innenquerschnitt des Tragrohres gebildet wird. Das Sleeve mit Handhabungsvorrichtung läßt sich daher in gleicher Weise wie die kompletten Zylinder auf einen Dorn eines Handhabungsroboters, eines Transportwagens, eines Regals und dergleichen aufstecken.By the tensioning device, the sleeve is thus connected to the support tube, in that the support tube extends coaxially through the sleeve. Consequently, that can Sleeve then be held on the support tube and transported without the relative thin-walled sleeve is subjected to deformation forces, resulting in damage could lead to the sleeve. Overall, the configuration corresponds from sleeve and handling device then a complete cylinder with continuous coaxial channel of the type described above, wherein the channel is formed by the inner cross section of the support tube. The sleeve with Handling device can therefore be in the same way as the complete Cylinder on a mandrel of a handling robot, a dolly, a Attach shelves and the like.

Die erfindungsgemäße Lösung ermöglicht es somit, das bereits für die Zylinder der Druckmaschine bestehende Logistiksystem in gleicher Weise für die Sleeves zu nutzen. So können beispielsweise Druckzylindersleeves vor oder nach dem Aufkleben der Klischees auf die erfindungsgemäße Handhabungsvorrichtung aufgespannt werden und dann mit Hilfe dieser Handhabungsvorrichtung auf dornartige Halter eines Transportwagens aufgesteckt werden, mit dem sie zu einem Lager transportiert werden. Das Lager kann seinerseits dornartige Halter aufweisen, auf die sich je nach Bedarf komplette Druckzylinder oder die mit der Handhabungsvorrichtung versehenen Sleeves aufstecken lassen. Im Fall eines voll- oder halbautomatischen Lagers kann ein Handlinggerät vorgesehen sein, das die nebeneinander und übereinander angeordneten Lagerplätze (Dorne) anfährt, um die Sleeves oder Druckzylinder an der jeweils gewünschten Lagerstelle einzulagern oder aus dem Lager zu entnehmen. Auch das Handlingerät kann seinerseits einen Dorn aufweisen, der in den Kanal des Druckzylinders bzw. das Tragrohr der Handhabungsvorrichtung für die Sleeves eingreift. Die aus dem Lager entnommenen Sleeves, die für den Einsatz in der Druckmaschine benötigt werden, können mit Hilfe des Handlingsgerätes auf einen wiederum mit dornartigen Haltern bestücken Wagen überführt und mit diesem zur Druckmaschine gefahren werden, wo sie auf die Zylinderkerne aufgeschoben werden. Auf entsprechende Weise können die aus der Druckmaschine entnommenen Sleeves wieder im Lager eingelagert werden.The solution according to the invention thus makes it possible already for the cylinders the printing press existing logistics system in the same way for the sleeves to use. For example, Druckzylindersleeves before or after the Gluing the clichés on the handling device according to the invention be spanned and then using this handling device on thorn-like holder of a trolley are plugged, with which they to a Bearings are transported. The bearing can in turn thorn-like holder have on which, as needed, complete impression cylinder or with the Leave provided handling device provided sleeves. In the case of one fully or semi-automatic bearing can be provided a handling device, that moves to the side by side and stacked bins (spines), around the sleeves or impression cylinder at the respective desired bearing point to store or remove from the warehouse. Even the handling device can in turn have a mandrel, which in the channel of the printing cylinder or the Support tube engages the handling device for the sleeves. The from the camp removed sleeves, which are needed for use in the printing press can, with the help of the handling device on a turn with thorn-like Holders equip cars transferred and with this to the printing press be driven where they are pushed onto the cylinder cores. On appropriate Way, the withdrawn from the printing press sleeves be stored again in the warehouse.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous embodiments of the invention will become apparent from the dependent claims.

Bevorzugt ist die Spanneinrichtung an einem Ende des Tragrohres angeordnet, und auf dem Tragrohr ist in Abstand zu der Spanneinrichtung ein scheibenförmiges Stützelement angeordnet, das von dem eingespannten Sleeve mit geringem Spiel umgeben wird. Dadurch wird eine übermäßige Verformung des Sleeves vermieden, falls doch einmal äußere Kräfte direkt auf das Sleeve einwirken sollten. Darüber hinaus erleichtert das Stützelement das Aufschieben des Sleeves auf den Zylinderkern in der Druckmaschine. Wenn das Sleeve aufgeschoben werden soll, wird das Tragrohr der Handhabungsvorrichtung koaxial mit dem Zylinderkern in der Druckmaschine ausgerichtet, die Spanneinrichtung wird gelöst, und das Sleeve wird von Hand oder automatisch von der Handhabungsvorrichtung auf den Zylinderkern geschoben, wobei das Stützelement ein Abkippen des Sleeves verhindert, solange es noch nicht weit genug auf den Zylinderkern aufgeschoben ist.Preferably, the tensioning device is arranged at one end of the support tube, and on the support tube is a disc-shaped at a distance from the tensioning device Support member arranged by the clamped sleeve with low Game is surrounded. This will cause excessive deformation of the sleeve avoided if external forces act directly on the sleeve should. In addition, the support element facilitates the sliding of the sleeve on the cylinder core in the printing press. When the sleeve is pushed is to be, the support tube of the handling device is coaxial with the Aligned cylinder core in the printing press, the clamping device is released, and the sleeve is manually or automatically handled by the handling device pushed onto the cylinder core, wherein the support element tipping The sleeve prevents it, as long as it is not far enough on the cylinder core is deferred.

So wird insbesondere die Handhabung von Sleeves erleichtert, die - entsprechend der Druckbreite der Druckmaschine - eine große Länge von 2000 mm oder mehr haben.In particular, the handling of sleeves is facilitated, the - accordingly the printing width of the printing press - a great length of 2000 mm or have more.

Gemäß einer Weiterbildung der Erfindung kann am freien Ende des Tragrohres ein Zentrierstück vorgesehen sein, das an einen Achsstummel des Zylinderkerns oder an das Ende einer den Zylinderkern durchsetzenden maschinenfesten Achse ankuppelbar ist. Auf diese Weise wird eine präzise Ausrichtung des Sleeves in Bezug auf den Zylinderkern erreicht, so daß sich das Sleeve dann mühelos auf den Zylinderkern aufschieben läßt.According to one embodiment of the invention can at the free end of the support tube a centering piece may be provided which is connected to a stub axle of the cylinder core or to the end of a cylinder core passing through the machine-fixed axis can be coupled. In this way, a precise alignment of the sleeve in With respect to the cylinder core achieved, so that the sleeve then effortlessly postpone the cylinder core.

In Figur 1 ist in einer Seitenansicht ein Zylinderkern 10 einer Druckmaschine gezeigt, der auf einer maschinenfesten Achse 12 befestigt ist. Die Achse 12 ist auf einer Seite des Zylinderkerns 10, rechts in Figur 1, kippstabil in zwei Lagern 14, 16 gelagert. Am entgegengesetzten Ende des Zylinderkerns 10 ist die Achse 12 in einem entfernbaren Lager 18 gelagert. Dieses Lager wird gelöst und entfernt, wenn der Zylinderkern 10 von der Achse 12 abgezogen werden soll oder wenn ein Sleeve 20 auf den in der Maschine verbleibenden Zylinderkern 10 aufgeschoben werden soll. Nach Entfernen des Lagers 18 werden die Achse 12 und der Zylinderkern 10 auslegerartig durch die beiden Lager 14, 16 gehalten, so daß das Sleeve 20 ungehindert vom freien Ende her aufgeschoben werden kann.FIG. 1 is a side view of a cylinder core 10 of a printing machine shown mounted on a machine-fixed axis 12. The axis 12 is on one side of the cylinder core 10, right in Figure 1, tilt-stable in two camps 14, 16 stored. At the opposite end of the cylinder core 10 is the axis 12 stored in a removable bearing 18. This camp is loosened and removed when the cylinder core 10 is to be subtracted from the axis 12 or when a sleeve 20 is pushed onto the remaining cylinder core 10 in the machine shall be. After removing the bearing 18, the axis 12 and the cylinder core 10 like a cantilever held by the two bearings 14, 16, so that the sleeve 20 can be pushed freely from the free end.

Bei dem Sleeve 20, das in Figur 1 in einem axialen Schnitt gezeigt ist, handelt es sich im gezeigten Beispiel um ein Druckzylindersleeve, auf dessen äußerer Umfangsfläche in bekannter Weise mehrere Klischees 22 befestigt worden sind. Wahlweise könnte es sich bei dem Sleeve 20 jedoch auch z.B. um ein Rasterwalzensleeve einer Flexodruckmaschine handeln.The sleeve 20, which is shown in an axial section in FIG. 1, is in the example shown, a Druckzylindersleeve on the outer peripheral surface in a known manner, several clichés 22 have been attached. Optionally, however, sleeve 20 could also be e.g. around a grid roller sleeve act a flexographic printing machine.

Das Sleeve 20 ist auf einer Handhabungsvorrichtung 24 gehalten. Diese Handhabungsvorrichtung weist ein Tragrohr 26 auf, auf dem an einem Ende eine Spanneinrichtung 28 befestigt ist. Die Spanneinrichtung 28 hat die Form einer abgestuften Scheibe, die mit ihrem im Durchmesser reduzierten Abschnitt in das Ende des Sleeves 20 eingreift und die an einer Stelle ihres Umfangs durch einen von ihrer Mittelöffnung zum äußeren Umfangsrand durchgehenden Schlitz 30 unterbrochen ist, wie deutlicher aus Figuren 2 und 3 hervorgeht. In einer Wand des Schlitzes 30 ist ein Exzenter 32 gelagert, der mit Hilfe eines Spannhebels 34 gegen die gegenüberliegende Wand des Schlitzes gespannt werden kann. Auf diese Weise wird die Scheibe insgesamt etwas aufgeweitet, so daß ihr in das Sleeve 20 eingreifender Teil fest gegen die Innenfläche des Sleeves gespannt wird. Hierdurch wird das Sleeve 20 in einer frei auskragenden, koaxial zum Tragrohr 26 orientierten Position gehalten.The sleeve 20 is held on a handling device 24. This handling device has a support tube 26 on which at one end a Clamping device 28 is attached. The clamping device 28 has the shape of a graduated disc with its reduced diameter section in the end of the sleeve 20 engages and at one point of its circumference a continuous from its central opening to the outer peripheral edge slot 30 is interrupted, as apparent from Figures 2 and 3. In a Wall of the slot 30 is mounted an eccentric 32, which by means of a clamping lever 34 can be clamped against the opposite wall of the slot. In this way, the disc is slightly widened something, so that you in the Sleeve 20 engaging part tight against the inner surface of the sleeve stretched becomes. As a result, the sleeve 20 in a cantilevered, coaxial with Support tube 26 oriented position held.

Die Handhabungsvorrichtung 24 ist ihrerseits lösbar auf einen Halter 36 aufgesteckt, der einen in das Tragrohr 26 eingreifenden Dorn 38 aufweist.The handling device 24 is in turn removably attached to a holder 36, which has a mandrel 38 engaging in the support tube 26.

Mit Hilfe des Halters 36, der Teil eines Handhabungsroboters oder eines Transportwagens oder dergleichen sein kann, ist die Handhabungsvorrichtung 24 mit dem aufgespannten Sleeve 20 so an die Druckmaschine herangefahren worden, daß das Tragrohr 26 im wesentlichen koaxial mit der Achse 12 der Druckmaschine ausgerichtet ist. Ein mit einem Innenkonus versehenes Zentrierstück 40 am freien Ende des Tragrohres 26 erleichtert es, das Ende des Tragrohres an die Achse 12 anzukuppeln, so daß eine präzise Ausrichtung des Sleeves 20 auf den Zylinderkern 10 erreicht wird.With the help of the holder 36, the part of a handling robot or a trolley or the like, the handling device 24 is with the unfolded sleeve 20 has been moved to the printing press, that the support tube 26 is substantially coaxial with the axis 12 of the printing machine is aligned. A provided with an inner cone centering 40th at the free end of the support tube 26 makes it easier, the end of the support tube to the To couple axis 12, so that a precise alignment of the sleeve 20 on the Cylinder core 10 is achieved.

Auf dem Tragrohr 26 ist in Abstand zu der Spanneinrichtung 28, im gezeigten Beispiel etwa auf halber Länge des Sleeves 20, ein scheibenförmiges Stützelement 42 befestigt, das von der Innenfläche des Sleeves 20 mit geringem Spiel (beispielsweise in der Größenordnung von 1 mm) umgeben wird.On the support tube 26 is at a distance to the clamping device 28, shown in FIG Example about halfway along the sleeve 20, a disk-shaped support element 42 attached, that of the inner surface of the sleeve 20 with little play (for example of the order of 1 mm) is surrounded.

Um das Sleeve 20 auf den Zylinderkern 10 aufzuschieben, wird zunächst die Spanneinrichtung 28 mit Hilfe des Spannhebels 34 gelöst. Anschließend wird das Sleeve 20 beispielsweise von Hand in Richtung auf den Zylinderkern 10 verschoben, so daß das zuvor eingespannte Ende des Sleeves von der Spanneinrichtung 28 abrutscht. Das Sleeve wird dann ohne nennenswerte radiale Verlagerung durch das Stützelement 42 in Position gehalten. Beim weiteren Verschieben des Sleeves gleitet dessen anderes Ende auf eine Anlaufschräge am Ende des Zylinderkerns 10 auf, so daß das Sleeve wieder präzise auf den Zylinderkern 10 zentriert wird.To postpone the sleeve 20 on the cylinder core 10, the first Clamping device 28 solved by means of the clamping lever 34. Subsequently, will the sleeve 20, for example, moved by hand in the direction of the cylinder core 10, so that the previously clamped end of the sleeve of the clamping device 28 slips off. The sleeve is then without significant radial displacement held in position by the support member 42. When moving further the sleeve slides its other end on a run-on slope at the end of the cylinder core 10, so that the sleeve again precisely on the cylinder core 10 is centered.

Der Zylinderkern 10 weist in bekannter Weise ein Druckluftsystem mit in der Umfangsfläche liegenden Luftauslässen 44 auf, das über die Achse 12 mit Druckluft gespeist wird. Die Luftauslässe 44 sind insbesondere auf einem Kranz unmittelbar angrenzend an das freie Ende des Zylinderkerns 10 angeordnet. Sobald das Ende des Sleeves 20 auf dieses Ende des Zylinderkerns aufgeschoben worden ist, bewirkt daher die aus den Luftauslässen 44 austretende Druckluft eine leichte Aufweitung des Sleeves, so daß sich das Sleeve auf einem Luftkissen reibungsarm weiter auf den Zylinderkern 10 aufschieben läßt, wie in Figur 4 gezeigt ist. Wenn das Sleeve 20 ganz aufgeschoben ist und an einem Anschlag 46 am Ende des Zylinderkerns 10 anliegt, wird die Druckluftzufuhr unterbrochen, so daß das Sleeve schrumpft und dann fest auf dem Zylinderkern 10 sitzt. Die Handhabungsvorrichtung 24 wird dann mit Hilfe des Halters 36 weggefahren.The cylinder core 10 has in a known manner a compressed air system in the Peripheral surface lying air outlets 44, which over the axis 12 with Compressed air is fed. The air outlets 44 are in particular on a wreath arranged immediately adjacent to the free end of the cylinder core 10. As soon as the end of the sleeve 20 is pushed onto this end of the cylinder core has therefore causes the exiting the air outlets 44 compressed air a slight widening of the sleeve, so that the sleeve on an air cushion low friction on the cylinder core 10 can postpone, as shown in Figure 4 is. When the sleeve 20 is completely pushed and a stop 46th at the end of the cylinder core 10, the compressed air supply is interrupted, so that the sleeve shrinks and then sits firmly on the cylinder core 10. The Handling device 24 is then moved away with the aid of the holder 36.

Durch Umkehr der oben beschriebenen Vorgänge läßt sich das Sleeve 20 auch wieder vom Zylinderkern 10 abziehen und wieder auf die Handhabungsvorrichtung 24 überführen, so daß es in ein Lager oder dergleichen abtransportiert werden kann.By reversing the above-described operations, the sleeve 20 can also be remove again from the cylinder core 10 and back to the handling device Transfer 24 so that it transported to a warehouse or the like can be.

Für die Endphase der Aufschiebebewegung des Sleeves 20 auf den Zylinderkern 10 sowie für die Anfangsphase der Bewegung bei Abziehen des Sleeves vom Zylinderkern kann auch eine in der Druckmaschine installierte Hilfsvorrichtung benutzt werden, die das teilweise aufgeschobene Sleeve vollständig gegen den Anschlag 46 zieht und/oder das abzuziehende Sleeve ein Stück weit vom Anschlag 46 weg schiebt, wie in EP-A-1 090 754 beschrieben wird.For the final phase of the sliding movement of the sleeve 20 on the cylinder core 10 as well as for the initial phase of the movement when removing the sleeve from the cylinder core may also be installed in the printing machine auxiliary device be used, the partially deferred sleeve completely against the Stop 46 pulls and / or the deducted sleeve a little way from the stop 46, as described in EP-A-1 090 754.

Wahlweise ist es auch möglich, den Sleevewechselvorgang weiter zu automatisieren, beispielsweise dadurch, daß die oben beschriebene Handhabungsvorrichtung 24 mit einem Stellantrieb, beispielsweise einem hydraulischen oder pneumatischen Antrieb versehen wird, der die Spanneinrichtung 28 auf dem Tragrohr 26 verschiebt, um das Sleeve auf den Zylinderkern aufzuschieben. Gegebenenfalls sollte dann auch das Stützelement 42 verschiebbar sein, so daß es sich zusammen mit der Spanneinrichtung 28 in Richtung auf das freie Ende des Tragrohres 26 verschieben läßt. Bei der Rückkehrbewegung der Spanneinrichtung 28 in die Ausgangsstellung kann das Stützelement 42 beispielsweise magnetisch mitgenommen werden, bis es in seiner Ausgangsstellung an einem Anschlag anschlägt, während sich dann die Spanneinrichtung 28 allein weiter zum Ende des Tragrohres 26 bewegt.Optionally, it is also possible to further automate the sleeve change process, for example, characterized in that the handling device described above 24 with an actuator, such as a hydraulic or pneumatic Drive is provided, the tensioning device 28 on the Support tube 26 moves to postpone the sleeve on the cylinder core. Possibly should then be the support member 42 slidably so that it itself together with the tensioning device 28 in the direction of the free end of Can move support tube 26. During the return movement of the clamping device 28 in the starting position, the support member 42, for example, magnetic be taken along until it stops in its starting position strikes while then the clamping device 28 alone continues to End of the support tube 26 moves.

Auch anstelle des Spannhebels 34 kann eine pneumatische oder elektromechanische Einrichtung zum Spannen und Lösen der Spanneinrichtung 28 vorgesehen sein.Also, instead of the clamping lever 34 may be a pneumatic or electromechanical Device for clamping and releasing the clamping device 28 is provided his.

Schließlich ist es auch möglich an oder in der Handhabungsvorrichtung 24, beispielsweise an oder in der die Spanneinrichtung 28 bildenden Scheibe, eine vorzugsweise programmierbare Codierung, etwa in der Form eines Halbleiterbauelements oder in der Form eines Transponders anzubringen, die eine Identifizierung des Sleeves 20 und/oder des zugehörigen Lagerplatzes im Lager ermöglicht und die von einer in den Halter 36 integrierten Lesevorrichtung automatisch gelesen werden kann.Finally, it is also possible on or in the handling device 24, for example on or in the clamping device 28 forming disc, preferably programmable encoding, such as in the form of a semiconductor device or in the form of a transponder carrying an identification the sleeve 20 and / or the associated storage space in the warehouse allows and automatically read the reading device integrated in the holder 36 can be.

Figur 5 zeigt eine Spanneinrichtung 24 gemäß einer anderen Ausführungsform. Die Scheibe ist hier nicht durch einen radialen Schlitz unterbrochen, sondern weist statt dessen in dem im Durchmesser reduzierten Teil einen in eine Umfangsnut eingelassenen Klemmring 46 aus elastischem Material, beispielsweise aus Gummi auf, der etwas über die Umfangsfläche übersteht. Wenn das Sleeve 20 auf diese Umfangsfläche aufgeschoben wird, wie in Figur 6 gezeigt ist, so wird der Klemmring komprimiert, so daß er das Sleeve in Position hält.FIG. 5 shows a tensioning device 24 according to another embodiment. The disk is not interrupted here by a radial slot, but has instead in the reduced diameter part in a circumferential groove recessed clamping ring 46 made of elastic material, for example made of rubber, which protrudes slightly beyond the peripheral surface. If the sleeve 20 is pushed onto this peripheral surface, as shown in Figure 6, so the compression ring is compressed so that it holds the sleeve in position.
