Description

Die Erfindung betrifft eine Vorrichtung zum Wechseln von Druckplatten gemäß dem Oberbegriff von Anspruch 1.The invention relates to a device for changing printing plates according to the preamble of claim 1.

Bei Bogenoffsetdruckmaschinen wird zum Wechseln einer auf dem Plattenzylinder befindlichen Druckplatte zunächst die Spannung und Klemmung der dem Druckende der Druckplatte zugeordneten Kante gelöst um daraufhin die Druckplatte durch Rückwärtsdrehen des Plattenzylinders entnehmen zu können. Nachdem der Druckanfang des Plattenzylinders mit der dazugehörigen Klemmschiene eine bestimmte Stellung eingenommen hat, erfolgt das Lösen der Klemmung der Druckplattenvorderkante. Nachdem die Druckplatte aus dem Erfassungsbereich der Klemmschiene des Druckanfangs entnommen worden ist, kann eine neue Druckplatte in diesen Erfassungsbereich eingelegt und geklemmt werden. Durch Vorwärtsdrehen des Plattenzylinders wird die neue Druckplatte auf dessen Außenumfang aufgezogen. Sodann erfolgt das Einführen der hinteren Kante der Druckplatte in die zugeordnete Klemmschiene mit anschließendem Klemmen und Spannen.In sheetfed offset presses, one is changed on the Plate cylinder located pressure plate first the tension and Clamping the edge assigned to the printing end of the printing plate loosened to turn the pressure plate by turning the To be able to remove plate cylinders. After the beginning of printing Plate cylinder with the associated clamping rail a certain Has taken position, the clamping is released Printing plate front edge. After the printing plate is out of the detection area has been removed from the clamping rail at the start of printing, a new printing plate can be inserted in this detection area and get pinched. By turning the plate cylinder forward the new pressure plate mounted on its outer circumference. Then the rear edge of the pressure plate is inserted into the assigned clamping rail with subsequent clamping and clamping.

In der Vergangenheit sind eine Vielzahl von automatischen Druckplattenwechslern bekannt geworden, bei welchen das zuvorstehend beschriebene Entnehmen sowie Zuführen einer Druckplatte von bzw. zum Plattenzylinder selbsttätig durch Fördereinrichtungen erfolgt. Der Plattenzylinder weist dazu entsprechende Betätigungseinrichtungen auf, vermittels den das Klemmen und Spannen der Druckplatte handhabungsfrei erfolgt. Eine neu zuzuführende Druckplatte ist dabei in dem Druckplattenwechsler bereitstellbar und die dem Plattenzylinder zu entnehmende Druckplatte wird durch die Fördereinrichtungen in einen Aufnahmebehälter gefördert. In the past there were a variety of automatic plate changers become known, in which the above removal and feeding of a printing plate from or to the plate cylinder is done automatically by conveyors. For this purpose, the plate cylinder has corresponding actuating devices by means of the clamping and tensioning of the pressure plate done without handling. A new pressure plate to be fed is thereby available in the printing plate changer and the Plate cylinder to be removed printing plate is by the conveyor conveyed into a receptacle.

Ein Druckplattenwechsler in Form eines Magazins ist aus der DE 4 224 832 C2 bekannt. Dieser Druckplattenwechsler ist hierbei an der Auslegerseite des Druckwerkes vertikal verschiebbar und zusätzlich noch um eine horizontale Achse verschwenkbar angeordnet. Das quaderförmig ausgebildete Magazin beinhaltet dabei zuzuführende Druckplatten und nimmt ferner auch eine vom Plattenzylinder abgeförderte Druckplatte auf. Dieses Magazin reicht in den Raum zwischen zwei Druckwerken, so daß man bei einer Realisierung einer derartigen Lösung bestrebt ist, die Baumaße, welche in den Raum zwischen den Druckwerken hineinragen, möglichst klein zu halten. Dies bedingt aber wiederum, daß der Aufnahmebehälter für die gebrauchte Druckplatte - ebenfalls quaderförmig - relativ schmal bzw. eng wird. Eine vom Plattenzylinder abgeförderte Druckplatte weist wegen der Zylinderkrümmung und der an ihr geleisteten Druckarbeit eine zum Teil ausgeprägte Wölbung auf. Ferner sind durch die Klemmeinrichtungen insbesondere des Druckendes die Kantenbereiche der gebrauchten Druckplatte noch zusätzlich gekrümmt. Das Einfördern einer gewölbten und gekanteten gebrauchten Druckplatte in ein zu flachen, quaderförmig ausgebildeten Aufnahmebehälter wirkt dabei die Gefahr des Verkantens, so daß evtl. Störungen durch zusätzlichen Bauaufwand entgegen gewirkt werden muß.A printing plate changer in the form of a magazine is from the DE 4 224 832 C2 known. This pressure plate changer is on the delivery side of the printing unit can be moved vertically and additionally still pivotable about a horizontal axis. The cuboid-shaped magazine contains to be fed Printing plates and also takes one removed from the plate cylinder Pressure plate on. This magazine reaches into the space between two printing units, so that when implementing such The solution is the dimensions that are in the space between the Protrude printing units to keep them as small as possible. This requires but again that the receptacle for the used printing plate - also cuboid - becomes relatively narrow or narrow. A printing plate removed from the plate cylinder has because of the Cylinder curvature and the printing work done on it one Partly pronounced curvature. Furthermore, through the clamping devices especially the edge of the used end of the print Printing plate curved additionally. Feeding an arched and folded used printing plate in a too flat, cuboid trained receptacle acts here the risk of Tilting, so that possible disruptions due to additional construction work must be counteracted.

Aus der DE 3 940 796 C2 ist ebenfalls ein Druckplattenwechsler bekannt, der einen Aufnahmebehälter für eine gebrauchte Druckplatte integriert aufweist. Der Aufnahmebehälter für die gebrauchte Druckplatte ist oberhalb der als Transportrollen ausgebildeten Fördereinrichtung teilweise zum Plattenzylinder hin mit gekrümmt ausgebildet. In einen derartig geformten Aufnahmebehälter kann eine gekrümmt geformte gebrauchte Druckplatte wesentlich einfacher hereingefördert werden. Nachteilig ist aber bei dieser Einrichtung, daß zum einen die Fördereinrichtung relativ nah am Plattenzylinder angeordnet ist, so daß nicht nur dessen Zugänglichkeit behindert ist. Ferner ist der obere Teil des Aufnahmebehälters für die gebrauchte Druckplatte wiederum als gerader, flacher Schacht ausgeführt, so daß es hier wiederum durch Verkanten oder dgl. zu einem Blockieren oder Beschädigen der gebrauchten Druckplatte kommen kann.DE 3 940 796 C2 is also a printing plate changer known of a receptacle for a used printing plate has integrated. The receptacle for the used Pressure plate is above that designed as transport rollers Conveyor partly curved towards the plate cylinder educated. In such a shaped receptacle can curved shaped used printing plate much easier be promoted. The disadvantage of this facility is that on the one hand the conveyor is relatively close to the plate cylinder is arranged so that not only impedes its accessibility is. Furthermore, the upper part of the receptacle for the used printing plate in turn as a straight, flat shaft executed so that here again by tilting or the like blocking or damaging the used printing plate can come.

Ein oberhalb eines Druckwerkes verschwenkbar gelagerter Druckplattenwechsler ist aus der JP 61-248834A bekannt. Dieser Druckplattenwechsler befindet sich in einer Normalposition horizontal orientiert oberhalb des Druckwerkes. Zum Wechseln der Druckplatten wird dieser heruntergeschwenkt und an den Plattenzylinder angestellt. Wegen der quaderförmigen, flachen Ausbildung des Druckplattenwechslers sind hier ebenfalls Schwierigkeiten beim Abfordern gewölbter und sonstwie gekrümmter gebrauchter Druckplatten zu befürchten. A printing plate changer pivotally mounted above a printing unit is known from JP 61-248834A. This pressure plate changer is horizontally oriented in a normal position above the printing unit. This is used to change the printing plates swung down and placed on the plate cylinder. Because of the cuboid, flat design of the pressure plate changer here also difficulties in requesting arched and otherwise to fear curved used printing plates.

Gemäß der Erfindung ist vorgesehen, deren Aufnahmebehälter für die gebrauchten Druckplatten als separaten Teil des Druckplattenwechslers auszuführen. Der Aufnahmebehälter ist dazu an den Druckplattenwechsler an- und bezüglich diesem abstellbar gelagert. Durch diese Maßnahme ist es möglich den Druckplattenwechsler zum Zuführen der neuen aber auch Abfördern der alten Druckplatte an der Auslegerseite des Druckwerkes möglichst mit geringer Bautiefe auszuführen, den Aufnahmebehälter für die gebrauchte Druckplatte aber derartig zu gestalten, so daß eine Wölbung aufweisende Druckplatte weitestgehend störungsfrei in diesen einzufördern ist.According to the invention it is provided, the receptacle for the used printing plates as a separate part of the printing plate changer to execute. The receptacle is attached to the pressure plate changer on and stored with respect to this. By this measure it is possible to use the pressure plate changer to feed the new one also remove the old pressure plate on the boom side of the Execute printing unit with a shallow depth if possible Receiving container for the used printing plate, however, too shape, so that a curvature printing plate largely is to be conveyed into these without interference.

Gemaß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, daß der Aufnahmebehälter eine Krümmung aufweist, die in der Größenordnung liegt, welche eine vom Plattenzylinder abgeförderte gebrauchte Druckplatte aufgrund der Zylindergeometrie aufgeprägt aufweist. Der Aufnahmebehälter kann dabei im wesentlichen als eine Rahmenkonstruktion gefertigt sein, wobei die Druckplatte schonungsvoll durch Bürsten sowohl auf ihrer druckenden als auch der rückwärtigen Seite getragen wird. Insbesondere kann vorgesehen sein, daß die gebrauchte Druckplatte dem Aufnahmebehälter seitlich entnehmbar ist.According to a preferred development of the invention, that the receptacle has a curvature that is of the order of magnitude which is a used used by the plate cylinder Pressure plate has embossed due to the cylinder geometry.

Auf diesem Plattenzylinder 1 ist eine Druckplatte 2 aufgespannt, welche gewechselt werden soll. Klemm- und Spanneinrichtungen für die Druckplatten sind hierbei nicht dargestellt.Fig. 1 shows the printing unit of a sheetfed offset printing press with a plate cylinder 1 arranged therein. On this plate cylinder 1 a pressure plate 2 is clamped, which is to be changed. Clamping and tensioning devices for the pressure plates are included not shown.

An der Auslegerseite des Druckwerkes ist ein Druckplattenwechsler 3 angeordnet, der eine Fördereinrichtung für neue sowie gebrauchte Druckplatten 2, 5 in Form von Transportrollen aufweist. In den Druckplattenwechsler 3 ist durch eine an der Oberseite angeordnete Öffnung eine neue Druckplatte 5 bereitgestellt.On the delivery side of the printing unit there is a printing plate changer 3 arranged of a conveyor for new and used Has printing plates 2, 5 in the form of transport rollers. In the Printing plate changer 3 is arranged by a on the top Opening a new pressure plate 5 is provided.

Oberhalb des dargestellten Druckwerkes ist jeweils an den Seitengestellwanden durch Hebel 7, 8, 9, welche insgesamt ein Fünfgelenk bilden, ein Aufnahmebehälter 6 angelenkt. Dieser Aufnahmebehälter 6 ist dabei als ein gekrümmt geformter Schacht ausgebildet.Above the printing unit shown is the Side frame walls by lever 7, 8, 9, which a total Form five-joint, a receptacle 6 articulated. This receptacle 6 is designed as a curved shaft.

Nachdem, ausgehend von der Situation gemäß Fig. 1, das Druckende der gebrauchten Druckplatte 2 freigegeben worden ist, erfolgt durch ein Rückwärtsdrehen des Plattenzylinders 1 (Pfeil) das Herausfördern des rückwärtigen Endes der Druckplatte 2 bis dieses in den Wirkbereich der Fördereinrichtung 4 gelangt. Zuvor wurde durch nicht dargestellte und beispielsweise an den Hebeln 9 angelenkte Betätigungseinrichtungen der Aufnahmebehälter 6 von der in Fig. 1 dargestellten Position (Grundposition während des Druckens) in die Plattenaufnahmeposition gemäß Fig. 2 verschwenkt. Der Aufnahmebehälter 6 weist dazu an der in Fig. 2 unten dargestellten Seite eine spaltförmige Öffnung auf. Leiteinrichtungen, welche die Druckplatte vom Plattenzylinder zu der Fördereinrichtung 4 leiten sind nicht dargestellt.After, starting from the situation shown in FIG. 1, the print end the used printing plate 2 has been released by a Turn the plate cylinder 1 (arrow) backwards to remove it the rear end of the pressure plate 2 to this in the effective range the conveyor 4 arrives. Previously it wasn't through Actuators shown and articulated, for example, on the levers 9 the receptacle 6 of that shown in Fig. 1 Position (basic position during printing) in the plate receiving position 2 pivoted. The receptacle 6 has in addition a gap-shaped on the side shown in Fig. 2 below Opening up. Guiding devices that remove the pressure plate from the plate cylinder lead to the conveyor 4 are not shown.

Nachdem die gebrauchte Druckplatte 2 mit ihrer hinteren Kante in den Wirkbereich der Fördereinrichtung 4 gelangt ist, übernimmt die Fördereinrichtung 4 das Hereinschieben der gebrauchten Druckplatte 2 in den an den Druckplattenwechsler 3 angestellten Aufnahmebehälter 6. Die Fördereinrichtung 4 (hier beispielsweise als Transportrollen dargestellt) fördern die gebrauchte Druckplatte 2 in den gekrümmt geformten Aufnahmebehälter 6 (Fig. 3).After the used pressure plate 2 with its rear edge in the effective range of the conveyor 4 has reached the Conveyor 4 pushing in the used pressure plate 2 in the receptacle placed on the pressure plate changer 3 6. The conveyor 4 (here, for example, as transport rollers shown) promote the used printing plate 2 in the curved shaped receptacle 6 (Fig. 3).

Nachdem die Druckplatte 2 vollständig in den Aufnahmebehälter 6 reingefördert ist, kann durch Ansteuern der nicht dargestellten Stellmittel der Aufnahmebehälter 6 wieder in seine Grundposition verschwenkt werden. Nun erfolgt das Zuführen der neuen Druckplatte 5 durch die Fördereinrichtung 4 des Druckplattenwechslers 3 zum Plattenzylinder 1. In an sich bekannter Weise wird die Vorderkante der Druckplatte 5 am Plattenzylinder geklemmt. Während des Aufziehens der neuen Druckplatte 5 wird dazu der Plattenzylinder 1 in Vorwärtsrichtung gedreht. After the pressure plate 2 is completely in the receptacle 6 is purely promoted, by driving the not shown Adjustment means of the receptacle 6 back to its basic position be pivoted. Now the new printing plate is fed 5 by the conveyor 4 of the printing plate changer 3 to Plate cylinder 1. In a manner known per se, the leading edge the pressure plate 5 clamped on the plate cylinder. While pulling up For this purpose, the new printing plate 5 becomes the plate cylinder 1 in the forward direction turned.

Wie voranstehend erwähnt ist der Aufnahmebehälter 6 für die gebrauchte Druckplatte zwei an seinen beiden formatäußeren Enden durch je ein durch die Hebel 7, 8, 9 gebildetes Fünfgelenk oberhalb des Druckwerkes angelenkt. Um dem an sich zwanglosen Fünfgelenk der Hebel 7, 8, 9 in Verbindung mit einem Teil des Aufnahmebehälters als Koppel eine Zwangsführung aufzuprägen, ist an dem Hebel 7 eine Kurve 10 fest angebracht, deren konkave Seite mit jeweils einem am Hebel 9 drehbar angebrachten Rolle 11 zusammenwirkt (Fig. 5 und 6). Durch diese Zwangsführung der Kurve 10 durch die Rolle 11 sowie die Geometrie der Anlenkungen und Abmessungen der Hebel 7, 8, 9 führt der Aufnahmebehälter 6 die geforderte Anstellbewegung ausgehend von der Grundposition gemäß Fig. 5 zu der Aufnahmeposition für eine hier nicht dargestellte gebrauchte Druckplatte gemäß Fig. 6 aus. Der Druckplattenwechsler, aus welchem heraus die gebrauchte Druckplatte in den Aufnahmebehälter 6 gefördert wird, ist in den Fig. 5 und 6 nicht dargestellt.As mentioned above, the receptacle 6 is for the used one Printing plate two at each of its two outer ends by one five-joint formed by levers 7, 8, 9 above the printing unit articulated. To the lever 5, 8, 9 in connection with a part of the receptacle as a coupling to impress a positive guidance is a curve 10 on the lever 7 firmly attached, the concave side of each with a lever 9 rotatably mounted roller 11 cooperates (Fig. 5 and 6). By this positive guidance of the curve 10 by the roller 11 and the Geometry of the linkages and dimensions of the levers 7, 8, 9 leads the receptacle 6 the required adjustment movement starting from 5 to the receiving position for a Used printing plate, not shown here, according to FIG. 6. The printing plate changer, from which the used printing plate is conveyed into the receiving container 6, is in Fig. 5th and 6 not shown.

Fig. 7 zeigt perspektivisch den an der Auslegerseite des Druckwerks angebrachten Druckplattenwechsler mit einer darin bereitgestellten dem Plattenzylinder (nicht dargestellt) zuzuführenden neuen Druckplatte 5. Der Aufnahmebehälter für die gebrauchte Druckplatte (nicht dargestellt) ist an den Druckplattenwechsler 3 (an dessen Oberseite) mit seiner Einführöffnung angestellt. Nachdem die nicht dargestellte gebrauchte Druckplatte in den Aufnahmebehälter 6 eingefördert worden ist, wird dieser in seiner Grundposition gemäß Fig. 8 verschwenkt. Die in Fig. 7 dargestellte dem Plattenzylinder zuzuführende neue Druckplatte 5 ist in der Darstellung gemäß Fig. 8 dem Plattenzylinder bereits zugeführt und auf diesen festgespannt worden. Die in den Aufnahmebehälter 6 hereingeförderte gebrauchte Druckplatte kann diesem nun während des Druckens eines neuen Auftrages entnommen werden. Dazu kann vorgesehen sein, daß die gebrauchte Druckplatte durch seitliche Entnahmeschlitze, also zu A- oder B-Seite entnehmbar ist.Fig. 7 shows in perspective that on the delivery side of the printing unit attached printing plate changer with a provided in it the new printing plate to be fed to the plate cylinder (not shown) 5. The receptacle for the used printing plate (not shown) is on the pressure plate changer 3 (at its Top) with its insertion opening. After that not used pressure plate shown in the receptacle 6th has been promoted, this is in its basic position Fig. 8 pivots. The plate cylinder shown in Fig. 7 The new printing plate 5 to be fed is shown in FIG. 8 already fed to the plate cylinder and clamped onto it been. The used conveyed into the receptacle 6 Printing plate can now do this while printing a new one Order can be removed. It can be provided that the used pressure plate through side removal slots, so to A- or B-side can be removed.

Fig. 9 zeigt, daß der Druckplattenwechsler 3 durch jeweils an den Seitengestellwänden angebrachte Führungsschienen 12, die als Teleskopführung ausgebildet sind, vertikal verschiebbar ist. Der Druckplattenwechsler 3 kann somit insbesondere über das Druckwerk hinaus verfahren werden, so daß sich eine Zugänglichkeit zum Farbwerk und insbesondere dem Farbkasten ergibt. Der in seiner Grundposition befindliche Aufnahmebehälter 6 ist durch die erfindungsgemäße Anlenkung dabei derartig verschwenkt worden, so daß er die vertikale Bewegbarkeit des Druckplattenwechslers 3 nicht behindert.Fig. 9 shows that the printing plate changer 3 by each Side frame walls attached guide rails 12, which as Telescopic guide are formed, is vertically displaceable. Of the Printing plate changer 3 can thus in particular via the printing unit be moved out so that there is accessibility to the Inking unit and in particular the ink fountain results. The one in his Basic position of the receiving container 6 is due to the invention Articulation has been pivoted in such a way that he the vertical mobility of the printing plate changer 3 is not hindered.

Wie bereits weiter obenstehend angedeutet, muß es sich bei dem Aufnahmebehälter 6 nicht um einen geschlossenen Behälter handeln, sondern dieser kann vielmehr als eine weitgehend offene Rahmenkonstruktion ausgebildet sein. Wesentlich ist dabei, daß der Aufnahmebehälter 6 an den Druckplattenwechsler 3 an- und bezüglich diesen abstellbar ist. Der erfindungsgemäße Aufnahmebehälter 6 weist darüberhinaus eine in Druckrichtung der Druckplatten verlaufende Krümmung auf, welche insbesondere in der Größenordnung liegt, welche eine gebrauchte Druckplatte nach der Entnahme des Plattenzylinders einnimmt. Durch die gekrümmte Formgebung des Aufnahmebehälters 6 ist somit das Hereinfördern einer gebrauchten Druckplatte wesentlich vereinfacht. Zum schonungsvollen Transport aber auch Halten der Druckplatte kann insbesondere vorgesehen sein, daß innerhalb des Aufnahmebehälters 6 streifenförmig Bürsten angeordnet sind, welche die Druckplatte an ihrer druckenden aber auch rückwärtigen Seite tragen. As already indicated above, it must be the Receptacle 6 is not a closed container, Rather, it can be used as a largely open frame construction be trained. It is essential that the receptacle 6 on the printing plate changer 3 and with respect to this can be switched off. The receptacle 6 according to the invention has moreover one running in the printing direction of the printing plates Curvature, which is in particular of the order of magnitude, which is a used printing plate after removing the plate cylinder occupies. Due to the curved shape of the receptacle 6 is thus the bringing in of a used printing plate much simplified. For gentle transport too Holding the pressure plate can be provided in particular that brushes arranged in strips in the receptacle 6 are, which the printing plate on its printing but also on the back Wear side.
