Description

Das taktmäßige Anheben und Senken des Druckzylinders bei Zweitourenschnellpressen wird bekanntlich durch ein Exzenter ausgeführt, das gegen das' Zylinderlager drückt und dieses gegen die Wirkung von Federn nach abwärts preßt, die das Zylinderlager nach der Drehung des Exzenters wieder nach oben drücken. Wenn man nun mit einer kleineren Schrifthöhe arbeiten will, legt man dünne Unterlagen zwischen das Stützlager und das Zylinderlager. Außerdem muß man die Greiferkulisse, die mit dem Steuerbolzen zusammenarbeitet, in solcher Weise einstellen; daß sie sich trotz der Veränderung der Bewegung des Druckzylinders noch über den Steuerbolzien zu schieben vermag. Diese Art der Einstellung ist sehr timständlich und zeitraubend, und das Zusammenarbeiten zwischen Steuerbolzen und Greiferkulisse ist nicht stoßfrei, weil der Steuerbolzen nicht mitverstellt wird. Es ist daher die Aufgabe der Erfindung, eine Vorrichtung zu schaffen, die ein einwandfreies Zusammenarbeiten der Greiferkulisse und ihres Steuerbolzens auch bei einer veränderten Bewegung des Druckzylinders ermöglicht. The clockwise raising and lowering of the printing cylinder in two-turn high-speed presses is known to be carried out by an eccentric that presses against the 'cylinder bearing and this presses downwards against the action of springs which the cylinder bearing after turning the eccentric push it up again. If you want to work with a smaller font size, you put thin pads between the support bearing and the cylinder bearing. Besides, you have to adjust the gripper link, which works together with the control bolt, in such a way; that, despite the change in the movement of the printing cylinder, they are still on the Able to push tax bolts. This type of setting is very time-consuming and time-consuming, and the cooperation between the control pin and the gripper link is not smooth, because the control pin is not adjusted at the same time. It is therefore the object of the invention To create a device that allows the gripper link to work together properly and its control pin even if there is a change in the movement of the pressure cylinder.

Erfmdungsgemäß wird nun die Lagerung des Exzenters zum Anheben und Senken des Druckzylinders bei Zweitourenschnellpressen in der Weise ausgebildet, daß in einer am Lagerdeckel verstellbar befestigten Lagerplatte sowohl das Abstellexzenter als auch der Steuerbolzen gelagert sind, der mit der Greiferkulisse zusammenarbeitet. Hierdurch vidrd .ein Einstellen des Steuerbolzens vollkommen überflüssig, da er durch das Verstellen des Lagers in vollkommen gleicher Weise beeinflußt wird wie der Druckzylinder und die Greiferkulisse.According to the invention, the mounting of the eccentric is now used to raise and lower the Printing cylinder in two-turn high-speed presses designed in such a way that in an on Bearing cover adjustable mounted bearing plate both the parking eccentric as well the control bolt are stored, which cooperates with the gripper link. Through this vidrd. one adjustment of the control bolt completely superfluous, since he is completely the same by adjusting the bearing How is influenced how the pressure cylinder and the gripper link.

Die Abb. 1 und 2 der Zeichnung zeigen ein Ausführungsbeispiel der Erfindung in einem Längsschnitt und Querschnitt.Figs. 1 and 2 of the drawing show an embodiment of the invention in one Longitudinal section and cross section.

Das Abstellexzenter 1 drückt zum Zwecke des Anstellens des Druckzylinders auf das untere Stützlager 2 und damit auch gegen das Zylinderlager 3, so daß dieses den Druckzylinder 10 gegen die Form drückt und dabei die Feder 4 zusammendrückt. Das Abstellexzenter ι ist in einer Lagerplatte 5 gelagert, die mit Hilfe der Schrauben 6 an den Lagerdeckel 7 angeschraubt ist. Die Bolzen der Schrauben 6 gleiten in den Langlöchern 12 (Abb. 1), so daß ein Verstellen der Lagerplatte s möglich ist. In der Lagerplatte 5 ist nun zugleich der Steuerbolzen 8 gelagert, der mit der Greiferkulisse 11 in bekannter Weise zusammenarbeitet. Werden nun die Schrauben 6 gelöst und wird darauf die Lagerplatte 5 mit Hilfe der im Lagerdeckel 7 sitzenden Schraube 9 eingestellt, so ändert sich einerseits der Weg, den das Lager 3 mit dem Druckzylinder 10 zurücklegt, andererseits wird außerdem der Weg der am Druckzylinder 10 befestigten Greiferkulisse verändert. Diese Veränderung hat aber keinerlei .Nachteile, weil mit dem Verstellen der Lagerplatte S .auch der in ihr gelagerte- Steuerbolzen 8 entsprechend der Veränderung des Weges des Druckzylinders ι ο und der Greiferkulisse 11 eingestellt worden ist.The parking eccentric 1 presses for the purpose of adjusting the pressure cylinder on the lower support bearing 2 and thus also against the cylinder bearing 3, so that this the pressure cylinder 10 presses against the mold and thereby compresses the spring 4. The parking eccentric ι is stored in a bearing plate 5, which is screwed to the bearing cover 7 with the aid of the screws 6. The bolts of the Screws 6 slide in the elongated holes 12 (Fig. 1) so that the bearing plate s can be adjusted. In the bearing plate 5 is now at the same time the control pin 8 is supported, which is connected to the gripper link 11 in a known manner cooperates. If the screws 6 are now loosened and the bearing plate is on it 5 set with the help of the screw 9 seated in the bearing cover 7, so changes On the one hand, the path that the bearing 3 covers with the printing cylinder 10, on the other hand the path of the gripper link attached to the printing cylinder 10 is also changed. However, this change has no disadvantages, because with the adjustment of the bearing plate See also the control pin stored in it 8 according to the change in the path of the pressure cylinder ι ο and the gripper link 11 has been discontinued.
