Abstract
Description
Die Erfindung betrifft ein Verfahren zum Zuführen einer in einem Plattenmagazin bereitgestellten Druckplatte zu einem Plattenzylinder, der einen axial zum Plattenzylinder verlaufenden Zylinderkanal aufweist, in dem eine vordere Spanneinrichtung zur Aufnahme der Vorderkante der Druckplatte und eine hintere Spanneinrichtung zur Aufnahme der Hinterkante der Druckplatte angeordnet ist, wobei in der vorderen Spanneinrichtung Passelemente zur Aufnahme der Druckplatte in der Vorderkante zugeordneten Passaussparungen vorgesehen sind und diese aus einer oberen und einer unteren Klemmleiste besteht.The The invention relates to a method for feeding one in a disk magazine provided printing plate to a plate cylinder, the one axial to the plate cylinder extending cylinder channel, in the a front clamping device for receiving the front edge of the printing plate and a rear tensioner for receiving the trailing edge of Pressure plate is arranged, wherein in the front clamping device Matching elements for receiving the pressure plate in the front edge associated Passport recesses are provided and these from a top and a lower terminal strip exists.
Zum
Wechseln der Druckplatte auf einem Plattenzylinder einer Druckmaschine
ist es allgemein üblich,
die neue Druckplatte in einem Plattenmagazin zu deponieren. Ist
eine auf dem Plattenzylinder befindliche Druckplatte abgedruckt,
wird die hintere Spanneinrichtung geöffnet, wobei der Plattenzylinder sich
in einer solchen Position befindet, dass das aus der hinteren Spanneinrichtung
herausspringende Druckplattenende zu dem Plattenmagazin geführt werden
kann. Durch Drehen des Plattenzylinders entgegen der Betriebsdrehrichtung
wird die abgedruckte Druckplatte abgeführt. Wenn die vordere Spanneinrichtung
in einer dem Plattenmagazin zugeordneten Position angelangt ist,
wird die vordere Spanneinrichtung geöffnet und die abgedruckte Druckplatte
in das Plattenmagazin gefördert.
Danach wird die neue Druckplatte, die ggf. durch im Plattenmagazin
vorgesehene Vorpassstifte lagegenau zu in der vorderen Spanneinrichtung
vorgesehenen Passelementen ausgerichtet ist, freigegeben und infolge des
Eigengewichts in die geöffnete
vordere Spanneinrichtung geführt,
wobei die neue Druckplatte von Passelementen der vorderen Spanneinrichtung
aufgenommen wird, die in die der Vorderkante zugeordneten Passaussparungen
eingreifen (
Diese Verfahrensweise hat den Nachteil, dass bei großformatigen Druckmaschinen und entsprechenden Druckplatten diese ein großes Eigengewicht aufweisen, welches dazu führt, dass durch das Anlegen der Druckplatten an den Passstiften der Grund der Passaussparungen deformiert wird. Das Problem tritt aber auch bei kleinformatigen Druckmaschinen dann auf, wenn der Weg zwischen den die Druckplatten im Plattenmagazin haltenden Vorpassstiften und den in der vorderen Spanneinrichtung vorgesehenen Passelemente groß ist. Das führt zu Produktivitätsverlusten der Druckmaschine.These Procedure has the disadvantage that in large format printing machines and corresponding printing plates they have a large weight, which leads that by applying the pressure plates on the dowel pins of the reason the fitting recesses is deformed. The problem also occurs when small-format printing presses then on, if the way between the Vordruckstiften holding the printing plates in the disk magazine and the fitting elements provided in the front tensioning device is great. Leading to productivity losses the printing press.
Aufgabe der Erfindung ist es, das gattungsgemäße Verfahren so weiterzubilden, dass die Druckplatten problemlos mit der Vorderkante der vorderen Spanneinrichtung zugeführt werden können.task The invention is to develop the generic method so that the pressure plates smoothly with the front edge of the front Supplied tensioning device can be.
Erfindungsgemäß wird die Aufgabe durch ein Verfahren nach den Merkmalen des Anspruchs 1 gelöst.According to the invention Problem solved by a method according to the features of claim 1.
Durch das erfindungsgemäße Verfahren kann ohne Mehraufwand erreicht werden, dass die Druckplatten, die ein hohes Eigengewicht aufweisen oder vom Plattenmagazin bis zu den Passelementen der vorderen Spanneinrichtung einen großen Weg zurücklegen, nicht mit großer Kraft mit den Passaussparungen an den Passelementen anlegen, wodurch Deformationen des Grundes der Passaussparungen vermieden werden. Bei der Zwischenpositionierung im durch die Klemmleisten gebildeten Aufnahmespalt setzt die Druckplatte mit der gesamten Vorderkante auf, so dass die Produktivität der Druckmaschine nachteilig beeinflussende Verformungen sicher vermieden werden können. Außerdem werden durch das erfindungsgemäße Verfahren die Druckplatten absolut frei von Verspannungen an den Passelementen angelegt.By the inventive method can be achieved without additional effort that the printing plates, the one have high net weight or from the disk magazine to the Passing elements of the front tensioning device travel a long way, not with big ones Apply force with the fitting recesses on the fitting elements, causing deformations the reason of the pass recesses are avoided. In the intermediate positioning in the formed by the terminal strips receiving gap sets the pressure plate with the entire leading edge on, thus adversely affecting the productivity of the printing press influencing deformations can be safely avoided. In addition, will by the method according to the invention the printing plates are absolutely free from tension on the fitting elements created.
