Description

Die bekannten Ausführungsformen von Greifern an An- und Ablegevorrichtungen sowie Druckzylindern von Druckmaschinen haben den Nachteil, daß sie genau in einer Ebene ausgerichtet werden müssen, damit die vorderen Griffflächen sämtlicher Greiferfinger das betreffende Werkstück gleichmäßig stark festhalten können.The known embodiments of grippers on depositing and depositing devices and printing cylinders of printing machines have the disadvantage that they are exactly in one Level must be aligned so that the front gripping surfaces of all gripper fingers be able to hold the workpiece in question evenly and firmly.

Gemäß der Erfindung wird eine sichere Einstellung jedes einzelnen Greifers unabhängig von den anderen auf der Greiferspindel sitzenden Greifern dadurch erreicht, daß eine am vorderen Ende U-förmig gebogene Blattfeder am Greifer ausgestanzte und abgebogene Lappen übergreift und sich unter Überspannung mit dem hinteren Ende auf die in bekannter Weise abgeflachte Greiferspindel legt.According to the invention, a safe setting of each individual gripper is independent achieved by the other grippers sitting on the gripper spindle in that one on front end U-shaped bent leaf spring on the gripper punched and bent tabs overlaps and under tension with the rear end on the known in Wise flattened looper spindle lays.

Der Erfindungsgegenstand ist auf der Zeichnung in einem Ausführungsbeispiel dargestellt. Es zeigen Abb. ι eine Ansicht im Längsschnitt nach a-b der Abb. 2, Abb. 2 eine Aufsicht und Abb. 3 einen Querschnitt nach c-d der Abb. 2.The subject of the invention is shown in the drawing in an exemplary embodiment. It shows Fig. 1 a view in longitudinal section from Fig. 2, Fig. 2 is a plan view and Fig. 3 is a cross section according to cd of Fig. 2.

ι ist der Greifer, der drehbar auf der Greiferspindel 2 sitzt und in die strichpunktierte Lage gebracht werden kann (Abb. 1). Das vordere, U-förmig gebogene Ende der Blattfeder 3 übergreift die am Greifer 1 ausgestanzten und abgebogenen Lappen 4, während das hintere Ende der Blattfeder auf eine Abflachung 5 der Greiferspindel 2 aufliegt und durch seine Häkenform ein selbsttätiges Herausspielen verhindert wird.ι is the gripper that rotates on the gripper spindle 2 sits and can be brought into the dot-dash position (Fig. 1). That the front, U-shaped bent end of the leaf spring 3 overlaps the punched out on the gripper 1 and bent tabs 4, while the rear end of the leaf spring on a flat 5 of the gripper spindle 2 rests and an automatic play out due to its hook shape is prevented.

Durch Drehen der Greiferspindel 2 entgegengesetzt der Uhrzeigerbewegung wird das hintere Ende der Blattfeder 3 angehoben, wodurch die Grifffläche des Greifers 1 einen Druck auf das Werkstück 6 und die darunter befindliche Unterlage 7 ausübt. Auf diese Weise werden bei mehreren auf der Greiferspindel 2 sitzenden Greifern etwa bestehende Höhenunterschiede zwischen den Griffflächen aufgehoben und eine selbsttätige Einstellung aller Greifer gewährleistet.Turning the gripper spindle 2 counter-clockwise movement the rear end of the leaf spring 3 is raised, whereby the gripping surface of the gripper 1 a Exerts pressure on the workpiece 6 and the underlying substrate 7. To this In the case of several grippers seated on the gripper spindle 2, there are approximately existing ones Height differences between the gripping surfaces eliminated and an automatic adjustment of all grippers guaranteed.

Das seitliche Verstellen des Greifers in der Längsachse der Greiferspindel 2 kann ohne jedes Werkzeug durch Anheben der Blattfeder 3 in die in Abb. 1 punktierte Stellung vorgenommen werden, um den Greifer über irgendeine der Abflachungen 5 der Greiferspindel 2 anzubringen.The lateral adjustment of the gripper in the longitudinal axis of the gripper spindle 2 can be done without each tool by lifting the leaf spring 3 into the position dotted in Fig. 1 be made to the gripper over any of the flats 5 of the gripper spindle 2 to be attached.
