Description

Die Erfindung betrifft einstellbare Greiferunterlagen an Schwinganlagen von Bogendruckmaschinen, die im Abstand der Papierstärke senkrecht über dem Anlegetisch zusammen mit den Greifern den Bogen übernehmen und an den Zylinder abgeben.The invention relates to adjustable gripper pads on vibratory systems of sheet-fed printing machines, which are positioned vertically above the feed table at the same distance as the paper thickness together with the grippers, take over the sheet and deliver it to the cylinder.

Bisher wurden die Greiferunterlagen mit großem Zeitaufwand einzeln bei stillstehender Maschine auf die vorgesehene Papierstärke eingestellt.So far, the gripper pads have been taken individually and took a great deal of time set to the intended paper thickness when the machine is at a standstill.

Bei der Erfindung werden die als Bolzen ausgebildeten Greiferunterlagen in dem auf der Schwingachse sitzenden Schwingbalken radial gleitend gelagert und am hinteren, gegen die Achse gerichteten Ende durch eine Querleiste verbunden. Unter Federdruck drückt die Querleiste gegen ein exzentrisch auf der Schwingachse drehbar gelagertes Rohr, so daß durch Drehen des exzentrischen Rohres die Greiferunterlagen auf die vorgesehene Papierstärke eingestellt werden können. Die Einstellung erfolgt nach einer seitlich am Rohr angebrachten Skala.In the invention, the gripper pads are designed as bolts in the swing beam seated on the swing axis and mounted so as to slide radially connected at the rear end facing towards the axis by a crossbar. Under Spring pressure pushes the cross bar against an eccentric rotatable on the swing axis stored tube, so that the gripper pads by turning the eccentric tube can be adjusted to the intended paper thickness. The setting is made according to a scale attached to the side of the tube.

An Hand der Zeichnung, die nach Abb. i einen Schnitt durch den Schwingbalken und nach Abb. 2 einen senkrechten Schnitt dazu darstellt, läßt sich die Wirkungsweise leicht erklären. Die im Schwingbalken 1 gelagerten Greiferunterlagen (2), sind gleitend in den. Bohrungen geführt und durch die Querleiste 3 verbunden. Die Querleiste wird durch Druckfedern 4 gegen das Rohr 5 gedrückt, das auf der Schwingachse 6 durch die Büchsen 7 und 8 exzentrisch drehbar gelagert ist. Durch Drehung des Rohres werden die Greiferunterlagen gemeinsam auf die vorgesehene Papierstärke nach Skala eingestellt, worauf das Rohr durch Klemmbacken 9 festgestellt wird.On the basis of the drawing, which is shown in Fig. I, a section through the vibrating beam and according to Fig. 2 shows a vertical section, the mode of operation easy to explain. The gripper pads (2) stored in the vibrating beam 1 are sliding in the. Drilled holes and connected through the cross bar 3. The cross bar will pressed by compression springs 4 against the tube 5, which on the swing axis 6 by the bushings 7 and 8 is rotatably mounted eccentrically. By rotating the pipe it will be the gripper pads are set together to the intended paper thickness according to the scale, whereupon the pipe is fixed by clamping jaws 9.
