Abstract

The device has an axially parallel tension rail arranged in a cylinder cavity (1). Pivotably fixed to the tension rail is a clamp rail (7). On the face side of the cylinder (2) is located a camshaft (9) which has two cam pairs (10,11). The first cam pair (10) moves the tension rail against the force of spring components (12) over cam rollers (13) into its accommodation position for the printing plate (5). After this, the second cam pair (11) via pins (17) opens the clamp rail (7) so far against the force off spring (18) - lever units (19) that the plate end can be positioned from rollers. By rotation of the camshaft in the opposite direction, firstly the clamp rail is closed from the spring lever units and then the tension rail is pushed from the spring components into the tension position.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Befestigen von biegsamen Druckplatten auf einem Plattenzylinder von Rotationsdruckmaschinen.The invention relates to a device for fastening flexible printing plates on a plate cylinder of rotary printing machines.

Eine bekannte Ausführung dieser Art (DE 37 31 039 A1) offenbart eine Klemmvorrichtung für biegsame Druckplatten, bei der Hebelelemente über Pneumatik- oder Hydraulikelemente die Druckplatte festklemmen und spannen. Bei dieser bekannten Ausführung ist es erforderlich, daß das pneumatische oder hydraulische Druckmedium während des gesamten Maschienenlaufs einen konstanten Druck erzeugt, um eine gleichmäßige Spannung der Druckplatte zu gewährleisten.A known embodiment of this type (DE 37 31 039 A1) discloses a clamping device for flexible pressure plates, in which lever elements clamp and tension the pressure plate via pneumatic or hydraulic elements. In this known embodiment, it is necessary for the pneumatic or hydraulic pressure medium to generate a constant pressure during the entire machine run in order to ensure a uniform tensioning of the pressure plate.

Die EP 0 444 219 A1 zeigt eine Vorrichtung zum Befestigen von biegsamen Druckplatten auf einem Plattenzylinder einer Rotationsdruckmaschine, bei der ein Einklemmen und Spannen der Druckplatte während des Betriebes ohne Energiezufuhr möglich ist. Diese weist gemäß dem Obergriff des Anspruchs 1 eine achsparallel in einer Zylindergrube angeordnete Spannschiene auf, mit einer an der Spannschiene schwenkbar befestigten Klemmschiene, mit einer am Zylinder stirnseitig gelagerten Nockenwelle, die zwei Nockenpaare aufweist, wobei das erste Nockenpaar die Spannschiene entgegen der Kraft von Federelementen in ihre Aufnahmeposition für die Druckplatte verschiebt und danach das zweite Nockenpaar über Zapfen entgegen der Kraft von Feder -Hebeleinheiten die Klemmschiene soweit öffnet, daß das nachlaufende Plattenende von Rollen eingelegt werden kann, und beim Verdrehen der Nockenwelle in entgegengesetzter Richtung erst die Klemmschiene von den Feder -Hebeleinheiten geschlossen und danach die Spannschiene von den Federelementen in Spannstellung verschoben wird.EP 0 444 219 A1 shows a device for fastening flexible printing plates on a plate cylinder of a rotary printing press, in which the printing plate can be clamped and clamped during operation without the supply of energy. This has a tensioning rail arranged axially parallel in a cylinder pit, with a clamping rail pivotably attached to the tensioning rail, with a camshaft mounted on the end face of the cylinder and having two pairs of cams, the first pair of cams the tensioning rail against the force of spring elements moves into its receiving position for the pressure plate and then the second pair of cams via pins against the force of spring-lever units opens the clamping rail so far that the trailing plate end can be inserted by rollers, and when the camshaft is rotated in the opposite direction, the clamping rail is released from the spring -Lever units closed and then the tensioning rail is moved into the tensioning position by the spring elements.

Aufgabe der vorliegenden Erfindung ist es, das Klemmen und Spannen der Druckplatte zu vereinfachen und eine Vorrichtung zu schaffen, die während des Betriebs der Maschine ohne Energiezufuhr Einklemmen und Spannen der Druckplatte gewährleistet.The object of the present invention is to simplify the clamping and tensioning of the pressure plate and to provide a device which ensures that the pressure plate is clamped and tensioned during operation of the machine without the supply of energy.

Gemäß der Erfindung wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention, the object is solved by the features of claim 1.

Feder-Hebeleinheiten die Klemmschiene soweit öffnet, daß das nachlaufende Plattenende z. B. von einer Rolle eingelegt werden kann und beim Verdrehen der Nockenwelle in entgegengesetzter Richtung erst die Klemmschiene von den Federhebeleinheiten geschlossen und danach die Spannschiene von den Federelementen in Spannstellung verschoben wird. Bei dieser Lösung ist das Betätigen lediglich einer Nockenwelle erforderlich, wobei diese manuell oder von Stellmitteln betätigt werden kann. Weiterhin ist sowohl das Klemmen als auch das Spannen der biegsamen Druckplatte während des Betriebs der Maschine durch Federelemente gewährleistet, so daß eine konstante Klemm- und Spannkraft wirkt ohne daß hierfür Kräfte von außerhalb zugeführt werden müssen. Ein wesentlicher Vorteil ist auch dadurch erreicht, daß mit der Spannung der Druckplatte durch Federelemente eine Schrägstellung derselben zur Passenkorrektur ohne zusätzliche Stellvorgänge durchführbar ist.Spring lever units opens the clamping rail so far that the trailing plate end z. B. can be inserted from a roll and when the camshaft is rotated in the opposite direction, the clamping rail is first closed by the spring lever units and then the clamping rail is moved by the spring elements into the clamping position. With this solution, it is only necessary to actuate one camshaft, which can be actuated manually or by actuating means. Furthermore, both the clamping and the clamping of the flexible pressure plate during operation of the machine is ensured by spring elements, so that a constant clamping and clamping force acts without the need for external forces. A major advantage is also achieved in that with the tension of the pressure plate by spring elements an inclination of the same can be carried out for correcting the fit without additional adjustment processes.

In einer vorteilhaften Ausgestaltung der Erfindung sind die Federelemente zwischen Spannschiene und Nockenwelle angeordnet und die Feder-Hebeleinheiten sind zwischen Lagerarmen an der Spannschiene und Hebeln an der Klemmschiene angeordnet.In an advantageous embodiment of the invention, the spring elements are arranged between the tensioning rail and camshaft and the spring-lever units are arranged between bearing arms on the tensioning rail and levers on the clamping rail.

An embodiment of the invention is shown schematically in the drawings,
it shows:
Fig. 1
a partial cross section through a plate cylinder with a tensioned pressure plate,
Fig. 2
a partial cross section through a plate cylinder in which the printing plate end is inserted.

In einer Grube 1 des Plattenzylinders 2 ist eine Klemmeinrichtung 3 für das vorlaufende Plattenende und einer Vorrichtung 4 zum Befestigen einer biegsamen Druckplatte 5 auf dem Plattenzylinder 2 vorgesehen. Die Vorrichtung 4 besteht unter anderem aus einer achsparallel, in der Grube 1 angeordneten Spannschiene 6 und einer an der Spannschiene 6 befestigten Klemmschiene 7. Die Spannschiene 6 ist in der Grube 1 des Plattenzylinders 2 verschiebbar gelagert und trägt an ihren beiden Enden Bolzen 8, auf denen die Klemmschiene 7 schwenkbar gelagert ist.In a pit 1 of the plate cylinder 2, a clamping device 3 for the leading plate end and a device 4 for attaching a flexible pressure plate 5 to the plate cylinder 2 are provided. The device 4 consists, inter alia, of an axially parallel clamping rail 6 arranged in the pit 1 and a clamping rail 7 fastened to the clamping rail 6. The clamping rail 6 is slidably mounted in the pit 1 of the plate cylinder 2 and carries bolts 8 at both ends which the clamping rail 7 is pivotally mounted.

Zum Betätigen der Spannschiene 6 und der Klemmschiene 7 ist eine Nockenwelle 9 vorgesehen, die in den Stirnseiten des Plattenzylinders 2 drehbar gelagert ist. Die Nockenwelle 9 trägt zwei Nockenpaare 10, 11, wobei das Nockenpaar 10 die Spannschiene 6 entgegen der Kraft von Federelementen 12 über Nockenrollen 13 verschiebt. Hierbei sind die Federelemente 12 auf Bolzen 14 vorgesehen, die in der Spannschiene 6 längsverschiebbar gelagert sind und sich mit ihrem gegenüberliegenden Kopf 15 an der Nockenwelle 9 abstützen. Die Nockenrollen 13 sind an Hebelarmen 16 befestigt, die ebenfalls mit der Spannschiene verbunden sind.To actuate the tensioning rail 6 and the clamping rail 7, a camshaft 9 is provided, which is rotatably mounted in the end faces of the plate cylinder 2. The camshaft 9 carries two pairs of cams 10, 11, the pair of cams 10 displacing the tensioning rail 6 against the force of spring elements 12 via cam rollers 13. In this case, the spring elements 12 are provided on bolts 14, which are mounted in a longitudinally displaceable manner in the tensioning rail 6 and are supported with their opposite head 15 on the camshaft 9. The cam rollers 13 are attached to lever arms 16, which are also connected to the tensioning rail.

Das zweite Nockenpaar 11 drückt beim Verdrehen der Nockenwelle entgegen dem Uhrzeigersinn Zapfen 17, die an der Klemmschiene 7 befestigt sind nach oben, so daß die Klemmschiene 7 öffnet und die in Fig. 2 gezeigte Position einnimmt. Das öffnen der Klemmschiene 7 erfolgt ebenfalls gegen die Kraft von Federn 18, die von Hebeln 19 betätigt werden, die wiederum an der Klemmschiene 7 befestigt sind. Die Federn 18 sind hierbei über Stößel 20 betätigbar, die auf einer Seite über Zapfen 21 an den Hebeln 19 und auf der anderen Seite über Zapfen 22 an den Lagerarmen 16 befestigt sind.The second pair of cams 11 presses when the camshaft is rotated counterclockwise, pins 17 which are fastened to the clamping rail 7, so that the clamping rail 7 opens and assumes the position shown in FIG. 2. The opening of the clamping rail 7 also takes place against the force of springs 18, which are actuated by levers 19, which in turn are attached to the clamping rail 7. The springs 18 can be actuated via plungers 20, which are fastened on one side via pins 21 to the levers 19 and on the other side via pins 22 on the bearing arms 16.

In Fig. 1 ist die Druckplatte 5 zwischen Spannschiene 6 und Klemmschiene 7 eingespannt und die Spannschiene mit der Klemmschiene durch die Kraft der Federelemente 12 nach rechts verschoben, so daß die Druckplatte 5 auf der Mantelfläche des Plattenzylinders 2 gespannt ist. Hierbei ist die Nockenwelle 9 im Uhrzeigersinn in ihrer Ausgangsposition verdreht (wie gezeichnet). Wird nun die Nockenwelle 9 entgegen dem Uhrzeigersinn verdreht, so wird über die Nockenrolle 13 zunächst die Spannschiene 6 mit der Klemmschiene 7 nach links bewegt und somit die Druckplatte entspannt. Danach wird über das zweite Nockenpaar 11 und die Zapfen 17 die Klemmschiene 7 geöffnet, wie dies in Fig. 2 dargestellt ist. Hierbei befindet sich die Spannschiene 6 in ihrer linken Ausgangsposition. Wird nun eine neue Druckplatte 5 auf dem Plattenzylinder 2 aufgelegt, so wird diese zunächst von der Klemmeinrichtung 3 an ihrem vorderen Ende eingespannt und durch Drehen des Plattenzylinders 2 entgegen dem Uhrzeigersinn durch feststehend an den Seitengestellen gelagerte Rollen 23 auf die Mantelfläche des Plattenzylinders 2 aufgedrückt. Hat der Plattenzylinder nach etwa einer Umdrehung die in Fig. 2 gezeigte Position erreicht, so drücken die Rollen 23 das nachlaufende Plattenende 24 in die wiedergegebenen Stellung, so daß die weit öffnende Klemmschiene 7 geschlossen werden kann und das Plattenende 24 einspannt, wie dies in Fig. 1 gezeigt ist. Danach erfolgt durch Weiterdrehen der Nockenwelle 9 das Spannen der Druckplatte durch Verschieben der Spannschiene 6 mit der Klemmschiene 7 nach rechts.In Fig. 1, the pressure plate 5 is clamped between the clamping rail 6 and the clamping rail 7 and the clamping rail with the clamping rail is displaced to the right by the force of the spring elements 12, so that the pressure plate 5 is clamped on the outer surface of the plate cylinder 2. Here, the camshaft 9 is rotated clockwise in its starting position (as shown). If the camshaft 9 is now rotated counterclockwise, the tensioning rail 6 with the clamping rail 7 is first moved to the left via the cam roller 13 and the pressure plate is thus relaxed. The clamping rail 7 is then opened via the second pair of cams 11 and the pins 17, as shown in FIG. 2. Here, the tensioning rail 6 is in its left starting position. If a new printing plate 5 is now placed on the plate cylinder 2, it is first clamped by the clamping device 3 at its front end and pressed onto the outer surface of the plate cylinder 2 by rotating the plate cylinder 2 counterclockwise by means of rollers 23 fixedly mounted on the side frames. When the plate cylinder has reached the position shown in FIG. 2 after about one revolution, the rollers 23 press the trailing plate end 24 into the position shown, so that the wide-opening clamping rail 7 can be closed and the plate end 24 clamped, as shown in FIG 1 is shown. Then, by continuing to turn the camshaft 9, the pressure plate is tensioned by moving the tensioning rail 6 with the clamping rail 7 to the right.
