Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Fördern eines Bogens durch eine drucktechnische Maschine nach dem Oberbegriff des Anspruchs 1.The The invention relates to a device for conveying a sheet through a Printing machine according to the preamble of claim 1.
Zum Fördern von Bogen durch eine Druckmaschine werden Trommeln und Zylinder verwendet, an denen mindestens ein Bogen in Greifern gehalten ist. Um einen Bogen auf einer gewünschten Bahn zu fördern, werden Blas- oder Saugluftvorrichtungen eingesetzt, die eine Kraftwirkung auf den Bogen ausüben. Dabei ist es möglich, dass die Blas- oder Saugluft die Bogenkante verformt, an der die Greifer den Bogen halten. Eine verformte Bogenkante kann zu Positionierfehlern bei der Übergabe von einer Greiferreihe zu einer nachfolgenden Greiferreihe führen, so dass Druckfehler entstehen.To the Promote from bows through a printing press become drums and cylinders used, in which at least one sheet is held in grippers. To make a bow on a desired To promote rail Blowing or suction air devices are used, which has a force effect to exercise on the bow. It is possible that the blowing or suction air deforms the sheet edge at which the Gripper hold the bow. A deformed sheet edge can lead to positioning errors at the handover lead from a gripper row to a subsequent gripper row, so that printing errors arise.

Aufgabe der Erfindung ist es, eine Vorrichtung zum Fördern eines Bogens durch eine drucktechnische Maschine zu entwickeln, die eine Verbesserung der Genauigkeit und Zuverlässigkeit bei der Übergabe eines Bogens zwischen zwei Greiferbrücken ermöglicht.task The invention is a device for conveying a sheet through a to develop a printing machine that improves the Accuracy and reliability at the handover an arc between two gripper bridges allows.
Die Aufgabe wird mit einer Vorrichtung gelöst, welche die Merkmale nach Anspruch 1 aufweist. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The The object is achieved with a device which the features Claim 1. Advantageous embodiments emerge the dependent claims.
Gemäß der Erfindung wird mit mindest einem Abschottelement der Luftdurchtritt zwischen Übertragungstrommeln gedrosselt. Wenn Greiferreihen an den Übertragungstrommeln jeweils auf einer Greiferwelle angeordnet sind, dann können als Abschottelemente ineinander kämmende Dichtleisten vorgesehen sein, die an den Greiferwellen befestigt sind. Bei einer Bogendruckmaschine, bei der ein Bogen aus einer Greiferreihe einer Übertragungstrommel an eine Greiferreihe eines Druckzylinders übergeben wird, bei der der Druckzylinder mit einem Übertragungszylinder zusammen wirkt und bei der im Bauraum zwischen dem Übertragungszylinder, dem Druckzylinder und dem Übertragungszylinder eine Blasluftvorrichtung angeordnet ist, wird durch Dichtleisten zuverlässig verhindert, dass die Bogenübergabe durch Blasluft beeinträchtigt ist.According to the invention With at least one Abschottelement the air passage between transfer drums throttled. When gripper rows on the transfer drums respectively are arranged on a gripper shaft, then can as Abschottelemente into each other meshing Be provided sealing strips which are attached to the gripper shafts. In a sheet-fed press, in which a sheet of a row of grippers a transfer drum is transferred to a gripper row of a printing cylinder, in which the Printing cylinder with a transfer cylinder works together and in the space between the transfer cylinder, the impression cylinder and the transfer cylinder a blown air device is arranged is by sealing strips reliable prevents the sheet transfer affected by blowing air is.
