Abstract

The printing plate cassette for a printing machine has a cross-bar (8) and a stop face (9) and/or roller stop(10) These support the edge of the stack (4) of plates. they do not stretch across the whole width of the plates and the stop face is at an angle of more than 90 deg to the floor the cassette.

Description

Die Erfindung betrifft eine Druckplattenkassette für Druckmaschinen.The invention relates to a printing plate cassette for printing machines.

Es sind Einrichtungen zur Vereinzelung von Druckplatten bekannt (DE 197 41 895 A1), bei denen ein Druckplattenstapel auf einer Aufnahmefläche aufliegt, wobei die Aufnahmefläche an der Vorderseite durch einen die Aufnahmefläche begrenzenden Anschlag begrenzt wird. Mittels eines als Sauger ausgebildeten Zuführsystems wird die vom Druckplattenstapel zu vereinzelnde oberste Druckplatte erfasst, durch Anheben vom Druckplattenstapel getrennt, über den Anschlag gehoben und zum Druckformzylinder transportiert.Devices for separating printing plates are known (DE 197 41 895 A1), at which a stack of printing plates rests on a receiving surface, the receiving surface is limited on the front by a stop limiting the receiving area. By means of a feed system designed as a suction device, the feed plate stack closes individual top printing plate seized, separated from the printing plate stack by lifting, lifted over the stop and transported to the printing form cylinder.

Auf Grund der beim Druckplattenvereinzeln auftretenden Reibung der Plattenvorderkante an dem über die gesamte Druckplattenbreite reichenden, im rechten Winkel zur Aufnahmeflä­ che angeordneten Anschlag kommt es zu Druckplattenverformungen und im Extremfall zum Abschälen der Druckplatte von den Saugern.Due to the friction of the leading edge of the plate when separating the printing plates across the entire width of the printing plate, at right angles to the receiving surface che arranged stop there is pressure plate deformation and in extreme cases Peel off the pressure plate from the suction cups.

Des weiteren wird die Druckplattenunterseite durch die Anschläge beschädigt.Furthermore, the pressure plate underside is damaged by the stops.

Aufgabe der Erfindung ist die Schaffung einer Druckplattenbeschädigungen ausschließen­ den Druckplattenkassette.The object of the invention is to exclude the creation of pressure plate damage the printing plate cassette.

Erfindungsgemäß wird die Aufgabe durch die Kennzeichen des ersten Anspruchs gelöst.According to the invention, the object is achieved by the characterizing features of the first claim.

Nachfolgend wir die erfinderische Lösung an einem Ausführungsbeispiel näher beschrieben.The inventive solution is described in more detail using an exemplary embodiment.

In der Zeichnung zeigt:The drawing shows:

Fig. 1 Prinzip Druckplattenkassette Fig. 1 principle printing plate cassette

Fig. 2 Anschläge Fig. 2 stops

Fig. 3 Schnitt A-A gemäß Fig. 2 Fig. 3 section AA according to FIG. 2

Fig. 4 Schnitt B-B gemäß Fig. 2. Fig. 4 is a section BB in FIG. 2.

Die in Fig. 1 dargestellte, einem Druckformzylinder 1 einer Druckmaschine zugeordnete Druckplattenkassette 2 besteht aus einer Aufnahmeeinrichtung 5 und einem als Sauger aus­ gebildeten Zuführsystem 3.The printing plate cassette 2 shown in FIG. 1 and assigned to a printing form cylinder 1 of a printing press consists of a receiving device 5 and a feed system 3 formed as a sucker.

In der Druckplattenkassette 2 ist eine Druckplattenstapel 4 abgelegt. Die Druckplattenkas­ sette 2 für den Druckplattenstapel 4 wird durch einen Anschlag 7 begrenzt.A printing plate stack 4 is stored in the printing plate cassette 2 . The Druckplattenkas set 2 for the printing plate stack 4 is limited by a stop 7 .

Der über die gesamte Druckplattenbreite reichende Anschlag 7 besteht aus einer Anschlag­ traverse 8, mindestens einem nicht über die gesamte Druckplattenbreite reichenden Einzel­ anschlag 9 und/oder mindestens einem ebenfalls nicht über die gesamte Druckplattenbreite reichenden Rollenanschlag 10. An der Anschlagfläche 11 des Einzelanschlages 9 und des Rollenanschlages 10 liegt der Druckplattenstapel 4 an. Damit liegt der Druckplattenstapel 4 nicht mehr über die gesamte Druckplattenbreite, sondern nur noch an den gegenüber der Anschlagtraverse 8 vorstehenden Anschlagflächen 11 des Einzelanschlages 9 und/oder des Rollenanschlages 10 an. Die Anschlagflächen 11 sowohl des Einzelanschlages 9 als auch des Rollenanschlages 10 sind gegenüber der Auflagefläche der Aufnahmeeinrichtung 5 un­ ter einem Winkel größer 90°, beispielsweise 93° geneigt, angeordnet.The over the entire printing plate width stop 7 consists of a stop cross 8 , at least one not over the entire printing plate width single stop 9 and / or at least one also not over the entire printing plate width roller stop 10th The pressure plate stack 4 rests on the stop surface 11 of the individual stop 9 and the roller stop 10 . Thus, the printing plate stack 4 no longer lies across the entire printing plate width, but only against the stop surfaces 11 of the individual stop 9 and / or the roller stop 10 which protrude relative to the stop crossbar 8 . The stop surfaces 11 of both the individual stop 9 and the roller stop 10 are arranged at an angle greater than 90 °, for example 93 °, relative to the contact surface of the receiving device 5 .

Der Rollenanschlag 10 ist an seiner Oberkante mit einer Rolle 12 ausgestattet.The roller stop 10 is equipped with a roller 12 on its upper edge.

Beim vertikalen Anheben der obersten Druckplatte des Druckplattenstapels 4 steht die Druckplattenvorderkante auf Grund der geneigten Anschlagflächen 11 nicht mehr in Kontakt mit der Anschlagfläche 11 und Beschädigungen der Druckplattenvorderkante sind ausge­ schlossen.During vertical lift the uppermost printing plate of the printing plate stack 4, the printing plate leading edge is due to the inclined abutment surfaces 11 no longer in contact with the abutment surface 11 and damage to the printing plate leading edge are closed out.

Des Weiteren wird die Unterseite der dem Druckformzylinder 1 zuzuführenden Druckplatte nicht mehr über die Oberkante der Anschläge gezogen. Furthermore, the underside of the printing plate to be fed to the printing form cylinder 1 is no longer pulled over the upper edge of the stops.
