Abstract

An expander mechanism (12) is adjustably held on the end (22) of a shaft (14). The external diameter of the expander mechanism when not expanded at most equals the external diameter of the shaft, and, when expanded, is greater than the cylinder's (10) internal diameter. The expander mechanism has a bushing (26) which is screwed onto a threaded section (24) of the shaft-stub on which is a cone (30) over which the expandable claws (34) of the expander mechanism glide. The claws are positioned on a ring (28).

Description

Die Erfindung betrifft eine Vorrichtung zur axialen Fixierung eines Zylinders auf einer Welle einer Druckmaschine.The invention relates to a device for axially fixing a cylinder on a shaft of a printing press.

Druckmaschinen weisen üblicherweise eine Anzahl auswechselbarer Zylinder auf. Bei diesen Zylindern kann es sich etwa im Fall einer Flexodruckmaschine beispielsweise um die Druckzylinder oder auch um die Auftragwalzen handeln. Bei einem Zylinderwechsel wird der Zylinder axial von einem Ende der Welle abgezogen (EP-A-0 769 373). Bei einigen Bauformen bekannter Druckmaschinen ist der Zylinder so auf der Welle befestigt, daß der Zylinder und die Welle während des Druckbetriebs als eine Einheit rotieren. Ein Ende des Zylinders ist in diesem Fall durch eine Verdrehsicherung mit der Welle verbunden, und am anderen Ende ist der Zylinder durch eine lösbar auf der Welle angebrachte Fixiereinrichtung derart gegen axiale Verschiebung gesichert, daß die Verdrehsicherung am gegenüberliegenden Ende des Zylinders mit der Welle in Eingriff bleibt. Bei einem Zylinderwechsel muß dann zunächst die Fixiereinrichtung fixiert werden, damit sich der Zylinder von der Welle abziehen läßt. Der von der Welle abgezogene Zylinder wird dann bis zum nächsten Gebrauch in einem Regalwagen aufbewahrt. Die Befestigung des Zylinders auf dem Regalwagen erfolgt zumeist in der Weise, daß der Zylinder axial auf einen frei von dem Regalwagen aufragenden Dorn aufgeschoben wird.Printing presses typically have a number of interchangeable cylinders on. These cylinders can be used, for example, in the case of a flexographic printing press for example, the pressure cylinders or the application rollers. When changing cylinders, the cylinder is axially from one end of the Wave withdrawn (EP-A-0 769 373). With some types of known printing machines the cylinder is attached to the shaft so that the cylinder and rotate the shaft as one unit during printing. An end of In this case the cylinder is connected to the shaft by an anti-rotation device, and at the other end the cylinder is detachable on the The shaft-attached fixing device is secured against axial displacement in such a way that the anti-rotation device at the opposite end of the cylinder remains engaged with the shaft. When changing cylinders, then first the fixing device be fixed so that the cylinder is from the shaft pulls off. The cylinder withdrawn from the shaft then becomes stored in a shelf trolley for next use. The attachment of the Cylinder on the shelf cart is usually done in such a way that the cylinder is pushed axially onto a mandrel protruding freely from the shelf trolley.

Ein Nachteil dieses bekannten Systems besteht darin, daß die Fixiereinrichtung bei einem Zylinderwechsel ganz von der Welle entfernt und vorübergehend geeignet aufbewahrt werden muß, bis sie nach dem Aufschieben des neuen Zylinders wieder auf der Welle befestigt wird. Hierdurch wird eine Automatisierung des Zylinderwechsels erschwert.A disadvantage of this known system is that the fixing device completely removed from the shaft when changing cylinders and must be kept temporarily until it is postponed of the new cylinder is reattached to the shaft. This will automation of the cylinder change is difficult.

Aufgabe der Erfindung ist es deshalb, eine Vorrichtung zur axialen Fixierung des Zylinders zu schaffen, die einen schnelleren und einfacheren Zylinderwechsel ermöglicht.The object of the invention is therefore a device for axial fixation of the cylinder to create a faster and easier cylinder change enables.

Diese Aufgabe wird erfindungsgemäß gelöst durch einen verstellbar auf einem Wellenstummel am Ende der Welle gehaltenen Spreizmechanismus, dessen Außendurchmesser im ungespreizten Zustand höchstens gleich dem Außendurchmesser der Welle und im gespreizten Zustand größer als der Innendurchmesser des Zylinders ist.This object is achieved by an adjustable on a Stub shaft held at the end of the shaft, the spreading mechanism Outside diameter in the unexpanded state at most equal to that Outside diameter of the shaft and in the spread state larger than the inside diameter of the cylinder.

Diese Lösung hat den Vorteil, daß der Spreizmechanismus bei einem Zylinderwechsel nicht von der Welle entfernt zu werden braucht, sondern lediglich vom gespreizten in den ungespreizten Zustand überführt zu werden braucht, so daß sich der Zylinder über den Spreizmechanismus hinweg von der Welle abziehen läßt. Nach dem Aufschieben des neuen Zylinders wird der Spreizmechanismus wieder gespreizt, so daß er am Ende des Zylinders angreift und diesen gegen axiale Verschiebung auf der Welle sichert.This solution has the advantage that the expansion mechanism when changing cylinders does not need to be removed from the shaft, but only to be transferred from the spread to the unspread state needs, so that the cylinder over the expansion mechanism from the shaft pulls off. After the new cylinder has been pushed on, the Spreading mechanism again spread so that it engages at the end of the cylinder and secures it against axial displacement on the shaft.

Ein weiterer Vorteil dieser Lösung besteht darin, daß an den Zylindern keine baulichen Veränderungen erforderlich sind, so daß sich die Zylinder in gewohnter Weise auf den Dorn eines Lager- oder Transportgestells aufschieben lassen.Another advantage of this solution is that there are none on the cylinders structural changes are required so that the cylinders are in the usual way Push it onto the mandrel of a storage or transport frame to let.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Bevorzugt ist der Spreizmechanismus im gespreizten Zustand axial gegen das Ende des Zylinders spannbar, so daß eine sichere verspannende Fixierung des Zylinders auf der Welle erreicht wird. Dies läßt sich auf besonders elegante Weise dadurch erreichen, daß der Spreizmechanismus eine Buchse aufweist, die beispielsweise mittels Gewinde axial auf dem Wellenstummel verstellbar ist und auf der dem Zylinder zugewandten Seite spreizbare Klauen trägt oder abstützt, die dann durch axiale Verstellung der Buchse gegen das Ende des Zylinders spannbar sind. Die Axialbewegung der Buchse und der Klauen kann zugleich dazu benutzt werden, die Spreizbewegung der Klauen zu bewirken, beispielsweise indem auf dem Wellenstummel ein Konus angeordnet wird, auf den die Klauen bei der Axialbewegung aufgleiten. Die Klauen sind vorzugsweise elastisch in die ungespreizte Stellung vorgespannt, so daß sie beim Lösen der Buchse selbsttätig in den ungespreizten Zustand übergehen. Besonders vorteilhaft läßt sich dies durch eine eigenelastische Gestaltung der Klauen erreichen.In the spread state, the spreading mechanism is preferably axially against the End of the cylinder can be tensioned, so that a secure tensioning fixation of the cylinder on the shaft is reached. This can be particularly elegant Achieve in that the spreading mechanism has a socket, which can be adjusted axially on the shaft stub, for example by means of a thread is and on the side facing the cylinder expandable claws carries or supports, which then by axial adjustment of the socket against End of the cylinder can be clamped. The axial movement of the bushing and the Claws can also be used to spread the claws to effect, for example, by placing a cone on the stub shaft on which the claws slide during the axial movement. The claws are preferably elastically biased into the unspread position, so that they automatically release into the open state when the socket is released pass over. This can be particularly advantageous through an inherently elastic Achieve claw design.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert.

An exemplary embodiment of the invention is explained in more detail below with reference to the drawing.

shows an axial section through a spreading mechanism and one end of a cylinder which is axially fixed on a shaft by means of this mechanism;
Fig. 2
shows the expansion mechanism in the released state; and
Fig. 3
illustrates the process of changing cylinders.

In Figur 1 ist ein Ende eines Zylinders 10, beispielsweise einer Auftragwalze oder eines Druckzylinders einer Flexodruckmaschine dargestellt, der mit Hilfe eines Spreizmechanismus 12 axialfest auf einer drehbaren Welle 14 der Druckmaschine gehalten ist.. Der Zylinder 10 ist im gezeigten Beispiel zweischalig aufgebaut, mit einem Innenmantel 16 und einem Außenmantel 18, dessen Ende etwas über das Ende des Innenmantels übersteht, so daß an der Stirnseite des Zylinders eine umlaufende Stufe 20 gebildet wird.In Figure 1 is one end of a cylinder 10, for example an applicator roller or a printing cylinder of a flexographic printing machine shown with With the help of a spreading mechanism 12 axially fixed on a rotatable shaft 14 of the Printing press is held .. The cylinder 10 is in the example shown constructed with two shells, with an inner jacket 16 and an outer jacket 18, the end of which protrudes somewhat beyond the end of the inner jacket, so that a circumferential step 20 is formed on the end face of the cylinder.

Die Welle 14 weist am Ende einen axial vorspringenden Wellenstummel 22 auf, der am freien Ende einen Außengewindeabschnitt 24 mit reduziertem Durchmesser bildet.The shaft 14 has an axially projecting stub shaft 22 at the end on which at the free end an external thread portion 24 with reduced Diameter forms.

Der Spreizmechanismus 12 umfaßt eine auf den Außengewindeabschnitt 24 aufgeschraubte Buchse 26, einen axialfest und drehbar auf der Buchse 26 gehaltenen Klauenring 28 sowie einen Konus 30, der mit Hilfe eines Sprengrings 32 axialfest auf dem Wellenstummel 22 gehalten ist. Der Konus 30 liegt an der zwischen dem Wellenstummel 22 und dem Hauptteil der Welle 14 gebildeten Schulter an und verjüngt sich in Richtung auf das freie Ende des Wellenstummels. Der Klauenring 28 weist mehrere gleichmäßig auf dem Umfang verteilte eigenelastische Klauen 34 auf, die axial in Richtung auf den Konus 30 vorspringen und in dem in Figur 1 gezeigten Zustand durch den Konus elastisch gespreizt sind, so daß sie mit ihren freien Enden in der Stufe 20 des Zylinders 14 liegen. Eine weitere Spreizung der Klauen wird so durch den vorstehenden Rand des Außenmantels verhindert.The spreading mechanism 12 includes one on the male threaded portion 24 screwed bushing 26, an axially fixed and rotatably held on the bushing 26 Claw ring 28 and a cone 30 with the help of a snap ring 32 is held axially fixed on the stub shaft 22. The cone 30 lies on the formed between the stub shaft 22 and the main part of the shaft 14 Shoulder and tapers towards the free end of the Wave stub. The claw ring 28 has several evenly on the circumference distributed self-elastic claws 34, which axially towards the cone 30 project and in the state shown in Figure 1 through the cone are elastically spread so that they are in step with their free ends 20 of the cylinder 14 lie. A further spreading of the claws is done by prevents the protruding edge of the outer jacket.

Wenn die Buchse 26 fest auf den Gewindeabschnitt 24 aufgeschraubt wird, so wird der Klauenring 28 durch die Buchse gegen den Zylinder 14 gespannt, und die freien Enden der Klauen 34 sind fest an der Stirnseite des Innenmantels 16 des Zylinders in Anlage. Auf diese Weise wird eine axiale Verschiebung des Zylinders 10 auf der Welle 14 nach rechts in Figur 1 zuverlässig verhindert. Während des Betriebs der Druckmaschine rotieren der Zylinder 10 und die Spreizmechanismus 12 gemeinsam mit der Welle 14.If the bushing 26 is screwed tightly onto the threaded section 24, so the claw ring 28 is stretched through the bushing against the cylinder 14, and the free ends of the claws 34 are fixed to the face of the inner shell 16 of the cylinder in attachment. In this way there is an axial displacement of the cylinder 10 on the shaft 14 to the right in FIG. 1 reliably prevented. Rotate while the press is operating the cylinder 10 and the spreading mechanism 12 together with the shaft 14.

Wenn der Zylinder 10 ausgewechselt werden soll, so wird die Buchse 26 ein Stück weit von dem Gewindeabschnitt 24 abgeschraubt, wie in Figur 2 dargestellt ist. Der Klauenring 28 wird dabei durch einen Sprengring 36 mitgenommen. Die Klauen 34 werden daher von dem Konus 30 abgezogen und kehren aufgrund ihrer Eigenelastizität selbsttätig in den ungespreizten Zustand zurück. In diesem Zustand sind ihre äußeren Oberflächen mit der äußeren Umfangsfläche des Klauenrings 28 bündig. In dem in Figur 2 gezeigten Zustand ist daher der Außenumfang des Spreizmechanismus 12 an keiner Stelle größer als der Innendurchmesser des Innenmantels 16 des Zylinders 10. Folglich läßt sich der Zylinder 10 axial über den Spreizmechanismus 12 hinweg von der Welle 14 abziehen, wie in Figur 3 gezeigt ist.When the cylinder 10 is to be replaced, the bushing 26 becomes a Unscrewed far from the threaded portion 24, as shown in Figure 2 is. The claw ring 28 is entrained by a snap ring 36. The claws 34 are therefore withdrawn from the cone 30 and automatically return to the unspread state due to their inherent elasticity back. In this state, their outer surfaces are with the outer circumferential surface of the claw ring 28 flush. In that shown in Figure 2 Condition is therefore the outer circumference of the expansion mechanism 12 on none Place larger than the inner diameter of the inner jacket 16 of the cylinder 10. Consequently, the cylinder 10 can be axially via the expansion mechanism 12th Pull away from the shaft 14 as shown in Figure 3.

Während der Zylinder 10 vollständig abgezogen und in einem Regalwagen oder dergleichen abgelegt wird, bleibt der Spreizmechanismus 12 ständig mit der Welle 14 verbunden, und ein neuer Zylinder wird über den Spreizmechanismus hinweg wieder auf die Welle 14 aufgeschoben und dann durch Umkehrung des oben beschriebenen Vorgangs auf der Welle fixiert. Zum Lösen und Anziehen des Spreizmechanismus braucht lediglich die Buchse 26 mit Hilfe eines geeigneten Werkzeugs um die gut definierte Achse der Welle 14 gedreht zu werden. Dieser Vorgang läßt sich problemlos automatisieren.During the cylinder 10 completely pulled off and in a rack trolley or the like is stored, the spreading mechanism 12 remains constantly connected to the shaft 14 and a new cylinder is placed over the spreading mechanism pushed back onto the shaft 14 and then through Reversal of the process described above fixed on the shaft. To the The bushing 26 only needs to be released and tightened by the expansion mechanism with the help of a suitable tool around the well-defined axis of the shaft 14 to be rotated. This process can be automated easily.
