Description

Bogenanlegevorrichtung Die Erfindung betrifft eine Bogenanlegevorrichtung mit unterhalb des Anlegetisches gelagertem, nach unten zum Druckzylinder schwingendem Vorgreifer.Sheet feeding device The invention relates to a sheet feeding device with one mounted below the feed table and swinging downwards towards the printing cylinder Pre-grapple.

Es sind Bogenanlegevorrichtungen bekannt, bei denen der über der Anlage angeordnete Vorgreifer nach oben zum Druckzylinder hin schwingt und bei seinem Rückweg angehoben wird, um den einlaufenden Bogen ungehindert durchführen zu können. Zu diesem Zweck ist der Vorgreifer in rotierenden oder hin- und hergehenden Exzenterbüchsen gelagert. Bei wechselnder Papierstärke geschieht dabei das Einstellen durch Verschieben des Greiferauflagebalkens, der sowohl zum Anlegetisch wie auch zum Druckzylinder hin bei gleichen Abständen zu diesem einstellbar ist. Bei unterhalb des Anlegetisches liegenden Vorgreifern, wie solche bei Schön- und Widerdruckmaschinen Verwendung finden, ist eine derartige Anordnung jedoch nicht mehr brauchbar, da die Vorgreifer in der Anlage auf gleicher Höhe verbleiben, bei der Übergabe an den Druckzylinder dagegen auf die jeweilige Papierstärke einstellbar sein müssen.There are known sheet feeders in which the above the system arranged pregripper swings upwards towards the printing cylinder and on its way back is raised in order to be able to carry out the incoming sheet unhindered. to for this purpose the pre-gripper is in rotating or reciprocating eccentric bushes stored. If the paper thickness changes, the setting is done by moving it of the gripper support bar, which connects both to the feed table and to the printing cylinder is adjustable towards this at the same distances. At below the feed table lying pre-grippers, such as those used in perfecting presses find, such an arrangement is no longer usable because the pregrippers remain at the same height in the system when they are transferred to the printing cylinder however, must be adjustable to the respective paper thickness.

Dies wird erfindungsgemäß dadurch erreicht, daß der die Anhebebewegung des Vorgreifers steuernde. Exzenter in einem weiteren Exzenter gelagert ist, der eine parallele Verschiebung zum Anlegetisch ermöglicht, so daß die Höhe der Greiferauflagen in der Anlage gleichbleibt, zum Druckzylinder hin dagegen entsprechend der Papierstärke eingestellt werden kann. Durch diese Maßnahme ist eine einfache Einstellung des Vorgreifers auf die jeweils verwendete Papierstärke möglich.This is achieved according to the invention in that the lifting movement the pre-gripper controlling. Eccentric is mounted in a further eccentric, the allows a parallel shift to the feed table, so that the height of the gripper supports remains the same in the system, towards the printing cylinder, however, according to the paper thickness can be adjusted. This measure makes it easy to set the Pre-gripper to the respective paper thickness used.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing shown.

Die Bahn des Vorgreifers 1 ist in ausgezogenen Linien mit 2 bezeichnet. Diese Bewegung wird durch . Verdrehen des Exzenters 3 bewirkt. Um den Abstand gegenüber dem Druckzylinder 4 bei einer anderen Papierstärke einstellen zu können, ist der Exzenter 3 in einem weiteren Exzenter 5 gelagert, der seinerseits durch das Gestänge 6 so verstellt wird, daß der Abstand gegen die Anlage 7 gleichbleibt, während er sich gegen den Druckzylinder 4 der jeweiligen Papierstärke anpassen kann. Die Vorgreiferbahn bei einer größeren Papierstärke ist mit strichpunktierten Linien 8 angedeutet.The path of the pregripper 1 is denoted by 2 in solid lines. This movement is going through. Turning the eccentric 3 causes. To the distance opposite to be able to adjust the printing cylinder 4 with a different paper thickness, is the Eccentric 3 mounted in a further eccentric 5, which in turn is through the linkage 6 is adjusted so that the distance from the system 7 remains the same while he can adapt to the pressure cylinder 4 of the respective paper thickness. The pre-gripper track in the case of a greater paper thickness, it is indicated by dash-dotted lines 8.
