Description

Die Erfindung betrifft eine Vorrichtung zum Handhaben von auswechselbaren Zylindern einer Druckmaschine, mit einer Halteeinrichtung, in der ein Ende des Zylinders auslegeartig gehalten ist.The invention relates to a device for handling interchangeable Cylinders of a printing press, with a holding device in which one end of the cylinder is held in the manner of a design.

Druckmaschinen weisen typischerweise eine Anzahl auswechselbarer zylindrischer Bauteile wie Druckzylinder, Farbauftragwalzen und dergleichen auf, die im folgenden zusammenfassend als Zylinder bezeichnet werden sollen.Typically, printing presses have a number of interchangeable cylindrical ones Components such as printing cylinders, inking rollers and the like, which in the following shall be referred to collectively as cylinders.

Zum Handhaben dieser auswechselbaren Zylinder sind Roboter bekannt, mit denen der auszuwechselnde Zylinder automatisch aus der Druckmaschine entnommen und in einem hierfür vorgesehenen Lagergestell abgelegt werden kann. Anschließend kann dann mit Hilfe desselben Roboters ein anderer Zylinder aus dem Lagergestell entnommen und in der Druckmaschine installiert werden.Robots are known for handling these interchangeable cylinders, with the cylinder to be replaced automatically from the printing press removed and stored in a storage rack provided for this purpose can. Another cylinder can then be used with the same robot removed from the storage rack and installed in the printing press become.

In EP-B1-0 400 517 wird ein Roboter beschrieben, der auf Schienen verfahrbar an einer Seite der Druckmaschine angeordnet ist und eine Halteeinrichtung aufweist, mit der ein Achsstummel an einem Ende des auszuwechselnden Zylinders erfaßt werden kann, so daß der gesamte Zylinder auslegerartig nur von einer Seite her durch den Roboter gehalten wird. Die Halteeinrichtung dieses bekannten Roboters weist einen Zapfen auf, der axial in ein hierfür vorgesehenes Sackloch in dem stirnseitigem Ende des Achsstummels eingeführt werden kann. Weiterhin gehört zu der Halteeinrichtung ein zangenartiges Greifelement, das einen näher zur Mitte des Zylinders gelegenen Abschnitt des Achsstummels zangenartig von oben umgreift.EP-B1-0 400 517 describes a robot that can be moved on rails is arranged on one side of the printing press and a holding device with which an axle stub at one end of the to be replaced Cylinder can be detected, so that the entire cylinder boom-like is held by the robot from one side only. The holding device of this known robot has a pin which axially in one provided blind hole in the front end of the stub axle can be introduced. A holding device also belongs to the holding device Gripping element that is closer to the center of the cylinder Section of the stub grips like a plier from above.

Nachteile dieser bekannten Vorrichtung bestehen darin, daß der Roboter zunächst sehr genau in Bezug auf den auszuwechselnden Zylinder positioniert werden muß, damit der Zapfen in das Sackloch eingeführt werden kann, und daß ein relativ komplexer Mechanismus zum Öffnen und Schließen des zangenartigen Greifelements benötigt wird.Disadvantages of this known device are that the robot initially positioned very precisely in relation to the cylinder to be replaced must be so that the pin can be inserted into the blind hole, and that a relatively complex mechanism for opening and closing the pliers-like Gripping elements is needed.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art mit einer vereinfachten Halteeinrichtung zu schaffen. The object of the invention is a device of the type mentioned to create with a simplified holding device.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Halteeinrichtung ein den Zylinder von unten abstützendes Tragelement und ein auf dem Zylinder aufliegendes, gegenüber dem Tragelement axial nach außen versetztes Widerlager aufweist, die den Zylinder aufgrund seines Eigengewichts klemmend halten.This object is achieved in that the holding device a supporting element supporting the cylinder from below and one on the Cylinder lying, axially offset to the outside of the support element Has abutment, which the cylinder due to its own weight hold tight.

Wenn ein Ende des Zylinders, oder, spezieller, der an diesem Ende des Zylinders vorgesehene Achsstummel von der Halteeinrichtung erfaßt werden soll, so braucht lediglich das Tragelement von unten an den Achsstummel angelegt und das Widerlager von oben auf den Achsstummel aufgelegt zu werden. Wenn anschließend das Tragelement und das Widerlager gemeinsam angehoben werden, hat der Zylinder aufgrund seines Eigengewichts die Tendenz, um das Tragelement zu kippen. Das freie Ende des Achsstummels schwenkt dabei nach oben aus und wird somit fest von unten gegen das Widerlager gespannt, so daß der gesamte Zylinder klemmend und frei auskragend gehalten wird.If one end of the cylinder, or, more specifically, that end of the cylinder provided stub axles are detected by the holding device should, the support element only needs to be placed on the stub axle from below and the abutment to be placed on the stub axle from above. If the support element and the abutment are then raised together due to its own weight, the cylinder tends to to tilt the support element. The free end of the stub axle swings out upwards and is thus firmly against the abutment from below cocked so that the entire cylinder is jammed and cantilevered is held.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous refinements of the invention result from the subclaims.

Bevorzugt weist das Tragelement und/oder das Widerlager eine in Axialrichtung des Zylinders durchgehende Vertiefung auf, die ein Umfangssegment des Zylinders bzw. des Achsstummels aufnimmt, so daß eine stabile Lagefixierung des Zylinders erreicht wird.The support element and / or the abutment preferably has one in the axial direction of the cylinder through recess, which is a peripheral segment of the cylinder or the axle stub so that a stable position fixation of the cylinder is reached.

Wenn die Halteeinrichtung an einem Roboter angeordnet ist, um den Zylinder zu erfassen, zu transportieren und an anderer Stelle wieder freizugeben, so sollten das Tragelement und das Widerlager in vertikaler Richtung relativ zueinander beweglich sein. In einer besonders bevorzugten Ausführungsform wird dies dadurch erreicht, daß das Widerlager um eine waagerechte Achse pendelnd an einer Schwinge aufgehängt ist. Wenn der Zylinder freigegeben werden soll, kann dann der vertikale Abstand zwischen dem Tragelement und dem Widerlager einfach dadurch vergrößert werden, daß die Schwinge verschwenkt wird. Beim Erfassen des Zylinders kann die Schwinge beispielsweise mit Hilfe eines Stellzylinders in Richtung auf die vertikale Position vorgespannt werden, so daß das Widerlager mit hoher Anpreßkraft gegen den Scheitel des Zylinders bzw. des Achsstummels gespannt wird. Zum Ausgleich von Axialbewegungen des Widerlagers relativ zum Zylinder ist das Widerlager in diesem Fall vorzugsweise mit einer Rolle versehen.When the holding device is arranged on a robot, around the cylinder to record, to transport and to release again elsewhere, so the support element and the abutment should be relative in the vertical direction be movable to each other. In a particularly preferred embodiment this is achieved in that the abutment about a horizontal axis is suspended from a swinging arm. When the cylinder is released then the vertical distance between the support element and the abutment can be enlarged simply by the rocker is pivoted. When the cylinder is gripped, for example biased towards the vertical position using an adjusting cylinder be so that the abutment with high contact pressure against the Vertex of the cylinder or the stub axle is tensioned. To compensate Axial movements of the abutment relative to the cylinder is the abutment in this case preferably provided with a roller.

Im Rahmen der Erfindung können ein oder mehrere Halteeinrichtungen der oben beschriebenen Art auch an dem Lagergestell für die Zylinder ausgebildet sein, so daß die Zylinder in dem Lagergestell nach demselben Prinzip auslegerartig gehalten werden wie durch den Roboter. Dabei ist es möglich, daß der Roboter die Zylinder direkt an die betreffende Halteeinrichtung im Lagergestell übergeben kann. Sofern bei der Halteeinrichtung des Roboters das Tragelement oder das Widerlager vertikalbeweglich ist, können bei der Halteeinrichtung des Lagergestells sowohl das Tragelement als auch das Widerlager starr ausgebildet sein, da der Roboter in der Lage ist, den Zylinder zunächst in einer leicht gekippten Position in die Halteeinrichtung des Lagergestells einzuhaken.In the context of the invention, one or more holding devices of the Type described above also formed on the storage rack for the cylinder be so that the cylinders in the storage rack on the same principle boom be held as by the robot. It is possible that the robot directly connects the cylinders to the relevant holding device in the storage rack can pass. Provided that the holding device of the robot Supporting element or the abutment is vertically movable, can be in the holding device the bearing frame, both the support element and the abutment be rigid, since the robot is able to move the cylinder first in a slightly tilted position in the holding device of the storage rack hook up.

Häufig weisen die Zylinder einer Druckmaschine eine auswechselbare Zylinderhülse auf. Wenn der Zylinder für einen neuen Druckauftrag umgerüstet werden soll, wird diese Zylinderhülse axial vom Kern des Zylinders abgezogen und durch eine andere Zylinderhülse ersetzt. Die auslegerartige Fixierung der Achsstummel der Zylinder im Lagergestell bietet in diesen Fällen die vorteilhafte Möglichkeit, den Wechsel der Zylinderhülse direkt im Lagergestell vorzunehmen, da das auskragende Ende des Zylinders frei zugänglich ist. Gegenstand der Erfindung ist deshalb auch ein Verfahren zum Wechsel der Zylinderhülse unter Verwendung eines solchen Lagergestells.The cylinders of a printing press often have an interchangeable cylinder sleeve on. When the cylinder is converted for a new print job this cylinder sleeve is pulled axially from the core of the cylinder and replaced by another cylinder sleeve. The boom-like fixation the stub axle of the cylinder in the storage rack offers the most advantageous in these cases Possibility of changing the cylinder sleeve directly in the storage rack as the projecting end of the cylinder is freely accessible. object The invention is therefore also a method for changing the cylinder sleeve using such a storage rack.

Im folgenden werden bevorzugte Ausführungsbeispiele anhand der Zeichnung näher erläutert.The following are preferred exemplary embodiments with reference to the drawing explained in more detail.

In Figur 1 ist ein Seitenteil 10 einer Druckmaschine gezeigt. das eine im Schnitt dargestellte Konsole 12 bildet, in der ein Ende eines Zylinders 14, beispielsweise eines Druckzylinders mit einem axial vorspringenden Achsstummel 16 gelagert ist. Das Lager für den Achsstummel 16 weist einen lösbaren Lagerdeckel 18 auf, damit ein Auswechseln des Zylinders 14 ermöglicht wird.1 shows a side part 10 of a printing press. the one in Sectioned console 12 forms, in which one end of a cylinder 14, for example a pressure cylinder with an axially projecting stub axle 16 is stored. The bearing for the stub axle 16 has one releasable bearing cover 18 so that the cylinder 14 can be replaced is made possible.

Das Seitenteil 10 bildet im oberen Bereich eine Brücke 20, an der ein mehrachsiger Roboter 22 in der Richtung senkrecht zur Zeichenebene in Figur 1 verfahrbar ist. Der Roboter 22 dient zum Auswechseln von Zylindern der Druckmaschine, u.a. des gezeigten Zylinders 14, und ist hängend an der Brücke 20 montiert, so daß Bodenfreiheit im Bereich des Seitenteils 10 gewährleistet ist. Der Roboter trägt eine Halteeinrichtung 24, mit der der Achsstummel 16 des Zylinders 14 erfaßt werden kann und die mit Hilfe des Roboters in vertikaler Richtung sowie in den beiden horizontalen Richtungen senkrecht und parallel zur Zeichenebene in Figur 1 bewegbar ist. Zusätzlich kann die Halteeinrichtung 24 um eine durch einen vertikalen Arm 26 des Roboters gebildete Achse gedreht werden.The side part 10 forms a bridge 20 in the upper area, on the multi-axis robot 22 in the direction perpendicular to the plane of the drawing in FIG 1 is movable. The robot 22 is used to replace cylinders the printing press, etc. of the cylinder 14 shown, and is hanging on the Bridge 20 mounted so that ground clearance in the area of the side part 10th is guaranteed. The robot carries a holding device 24 with which the Axle stub 16 of the cylinder 14 can be detected and with the help of Robot in the vertical direction as well as in the two horizontal directions is perpendicular and parallel to the plane of the drawing in Figure 1. In addition can the holding device 24 by a vertical arm 26 of the Robot formed axis can be rotated.

Die Halteeinrichtung 24 weist im gezeigten Beispiel einen annähernd Cförmigen Rahmen 28 auf, dessen verlängerter unterer Schenkel am freien Ende ein Tragelement 30 für den Achsstummel 16 trägt. Das Tragelement 30 hat gemäß Figur 2 eine konkave Prismenform, so daß es stabil mit dem Achsstummel 16 in Eingriff treten kann.The holding device 24 has an approximately C-shaped in the example shown Frame 28 on, the elongated lower leg at the free End carries a support member 30 for the stub shaft 16. The support element 30 2 has a concave prism shape, so that it is stable with the stub axle 16 can engage.

Ein Widerlager 32 für den Achsstummel 16 ist mit Hilfe einer als Parallelogrammgestänge ausgebildeten Schwinge 34 pendelnd am oberen Schenkel des Rahmens 28 aufgehängt und mit Hilfe eines Stellzylinders 36, beispielsweise eines Pneumatikzylinders verschwenkbar. Das Widerlager 32 trägt eine Rolle 38, deren äußerer Umfang gemäß Figur 2 eine Hohlkehle bildet und mit dem oberen Scheitel des Achsstummels 16 in Eingriff gebracht werden kann.An abutment 32 for the stub shaft 16 is by means of a parallelogram linkage trained swing arm 34 swinging on the upper leg the frame 28 suspended and with the help of an actuating cylinder 36, for example of a pneumatic cylinder swiveling. The abutment 32 carries one Roll 38, the outer periphery of which forms a groove according to FIG. 2 and can be brought into engagement with the upper vertex of the stub shaft 16 can.

Wenn der Zylinder 14 ausgewechselt werden soll, wird der Roboter 22 zunächst in die in Figur 1 gezeigte Position gefahren. Anschließend wird der Rahmen 28 leicht angehoben, so daß sich das Tragelement 30 in einer relativ nahe an dem Seitenteil 10 gelegenen Position von unten an den Achsstummel 16 anlegt. wie in Figur 3 gezeigt ist. Durch Ausfahren des Stellzylinders 36 wird dann die Schwinge 34 in eine annähernd vertikale Position geschwenkt, so daß sich das Widerlager 32 auf das frei Ende des Achsstummels 16 absenkt und die Rolle 38 mit dem oberen Scheitelbereich des Achsstummels In Eingriff kommt, wie in Figuren 3 und 4 zu erkennen ist.When the cylinder 14 is to be replaced, the robot 22 is first moved into the position shown in Figure 1. Then the Frame 28 slightly raised so that the support member 30 in a relative close to the side part 10 position from below to the stub axle 16 creates. as shown in Figure 3. By extending the actuating cylinder 36 the rocker 34 is then pivoted into an approximately vertical position, so that the abutment 32 lowers on the free end of the stub shaft 16 and the roller 38 with the upper vertex region of the stub axle In Intervention comes, as can be seen in Figures 3 and 4.

In Figur 3 ist ist der Lagerdeckel 18 entfernt worden, so daß der Zylinder 14 mit Hilfe des Roboters nach oben aus den Lagern im Maschinengestell herausgehoben werden kann (Figur 7). Der Zylinder wird dabei auslegerartig allein an dem Achsstummel 16 gehalten und durch das Tragelement 30 und das in versetzter Position an dem Achsstummel angreifende Widerlager 32 gegen das durch das Eigengewicht des Zylinders verursachte Kippmoment stabilisiert.In Figure 3, the bearing cap 18 has been removed so that the cylinder 14th lifted up out of the bearings in the machine frame using the robot can be (Figure 7). The cylinder becomes cantilevered alone held on the stub shaft 16 and by the support member 30 and the abutment 32 engaging the stub axle in the offset position against the tipping moment caused by the cylinder's own weight stabilized.

In diesem Zustand kann der Zylinder 14 mit Hilfe des Roboters zu einem Lagergestell gebracht werden, das beispielsweise den in Figuren 5 und 6 gezeigten Aufbau aufweist. Im gezeigten Beispiel ist das Lagergestell als Lagerwagen 40 ausgebildet. Auf einem Fahrgestell 42 sind an einem Ende mehrere Paare von aufragenden Stützen 44, 46 montiert. Jedes Stützenpaar bildet im gezeigten Beispiel zwei Halteeinrichtungen 48 für die Achsstummel 16 von zwei in unterschiedlichen Höhen angeordneten Zylindern 14.In this state, the cylinder 14 can be moved to a storage rack using the robot brought, for example, that shown in Figures 5 and 6 Has structure. In the example shown, the storage rack is a storage trolley 40 trained. On a chassis 42 there are several at one end Pairs of towering supports 44, 46 mounted. Each pair of supports forms in Example shown two holding devices 48 for the stub axle 16 of two cylinders 14 arranged at different heights.

Wie bei der Halteeinrichtung 24 des Roboters werden auch die Halteeinrichtungen 48 jeweils durch ein Tragelement 50 und ein Widerlager 52 gebildet, die in axial versetzten Positionen von unten und von oben an dem Achsstummel 16 angreifen. Die Tragelemente 50 sind in diesem Fall starr und seitlich vorspringend an den Stützen 44 angeordnet, während die Widerlager 52 starr und seitlich vorspringend an den näher zum freien Ende des Achsstummels gelegenen Stützen 46 angeordnet sind. Gemäß Figur 6 haben die Tragelemente und Widerlager prismenförmige Einkerbungen, die eine stabile Fixierung der Achsstummel 16 ermöglichen.As with the holding device 24 of the robot, the holding devices are also 48 each formed by a support element 50 and an abutment 52, the axially offset positions from below and from above on the stub axle 16 attack. The support elements 50 are rigid and laterally in this case protruding on the supports 44, while the abutment 52nd rigid and projecting sideways to the closer to the free end of the stub axle located supports 46 are arranged. According to Figure 6, the support elements and abutments prism-shaped notches that provide a stable Allow the stub axle 16 to be fixed.

Die Zylinder 14 sind folglich mit ihren Achsstummeln 16 auslegerartig auf dem Lagerwagen gehalten, so daß sie von den Stützen 44 und 46 frei auskragen, wie am deutlichsten in Figur 5 zu erkennen ist. In Figur 5 sind die Zylinder 14 im Schnitt dargestellt, und man erkannt, daß jeder Zylinder auf seinem äußeren Umfang eine axial abziehbare Zylinderhülse 54 trägt. Aufgrund der Gestaltung der Halteeinrichtungen 48 ist es möglich, das Auswechseln der Zylinderhülsen 54 direkt im Lagerwagen 42 vorzunehmen. Da die Achsstummel 16 aufgrund des nicht unbeträchtlichen Eigengewichts der Zylinder 14 in den Halteeinrichtungen 48 verkanten, werden die Zylinder 14 stabil in der jeweiligen Halteeinrichtung 48 festgehalten. während die Zylinderhülse 54 unter Überwindung eines gewissen Reibungswiderstands abgezogen wird.The cylinders 14 are consequently cantilevered with their stub axles 16 the storage trolley is held so that it projects freely from the supports 44 and 46, as can be seen most clearly in FIG. 5. In Figure 5 are the cylinders 14 shown in section, and it can be seen that each cylinder on its outer circumference carries an axially removable cylinder sleeve 54. Due to the Design of the holding devices 48, it is possible to replace the Carry out cylinder sleeves 54 directly in the storage trolley 42. Because the stub axle 16 due to the not inconsiderable weight of the cylinders 14 tilt in the holding devices 48, the cylinders 14 are stable in the respective holding device 48 held. while the cylinder sleeve 54 is subtracted while overcoming a certain frictional resistance.

Figur 8 illustriert die Übergabe eines Zylinders 14 von der Halteeinrichtung 24 des Roboters an die Halteeinrichtung 48 des Lagerwagens. Der Stellzylinder 36 ist noch etwas weiter ausgefahren als in Figur 7, so daß das Widerlager 32 relativ zu dem Tragelement 30 noch etwas weiter abgesenkt ist. Hierdurch wird der Zylinder 14 in eine leicht gekippte Position gebracht. In dieser Position wird der Zylinder 14 mit Hilfe des Roboters zunächst auf der Seite der Stützen 44, 46 abgesenkt, von der das Tragelement 50 und das Widerlager 52 vorspringen. Anschließend wird die Halteeinrichtung 24 mit Hilfe des Roboters zur Seite bewegt, so daß der Achsstummel des Zylinders 14 zwischen das Tragelement 50 und das Widerlager 52 eintritt. Das Tragelement 30 und das Widerlager 32 der Halteeinrichtung 24 sind dabei zu dem Tragelement und dem Widerlager der Halteeinrichtung 48 axial versetzt. Schließlich wird der Stellzylinder 36 zurückgezogen, so daß das Widerlager 32 den Achsstummel freigibt. Der Zylinder 14 kippt dann in seine waagerechte Position und wird in dieser Position durch das Tragelement 50 und das Widerlager 52 des Lagerwagens gehalten. FIG. 8 illustrates the transfer of a cylinder 14 from the holding device 24 of the robot to the holding device 48 of the warehouse truck. The actuator cylinder 36 is extended a little further than in Figure 7, so that the abutment 32 is lowered somewhat further relative to the support element 30. As a result, the cylinder 14 is brought into a slightly tilted position. In In this position, the cylinder 14 is first placed on the robot Side of the supports 44, 46 lowered, of which the support member 50 and the abutment 52 project forward. Then the holding device 24 with Help the robot move to the side so that the stub axle of the cylinder 14 occurs between the support member 50 and the abutment 52. The support element 30 and the abutment 32 of the holding device 24 are to the Carrying element and the abutment of the holding device 48 axially offset. Finally, the actuating cylinder 36 is withdrawn, so that the abutment 32 releases the stub axle. The cylinder 14 then tilts into its horizontal Position and is in this position by the support member 50 and the abutment 52 of the warehouse car is held.

Durch Umkehrung des oben beschriebenen Vorgangs kann ein Zylinder auch wieder aus dem Lagerwagen 40 entnommen und in die Druckmaschine eingesetzt werden.By reversing the process described above, a cylinder can also removed again from the storage carriage 40 and into the printing press be used.

Gemäß einer Abwandlung des beschriebenen Ausführungsbeispiels ist es auch möglich, daß die Halteeinrichtung 24 des Roboters und die Halteeinrichtung 48 des Lagerwagens an verschiedenen Achsstummeln auf entgegengesetzten Seiten des Zylinders 14 angreifen. Ebenso ist es möglich, das Tragelement 50 oder das Widerlager 52 der Halteeinrichtung 48 vertikalbeweglich auszubilden, damit das Einführen des Achsstummels erleichtert wird.According to a modification of the described embodiment, it is also possible that the holding device 24 of the robot and the holding device 48 of the warehouse car on different axles on opposite Attack sides of cylinder 14. It is also possible to use the support element 50 or the abutment 52 of the holding device 48 to be vertically movable, so that the insertion of the stub axle is easier.
