Description

Bei Rotationsdruckmaschinen wird es als ein Nachteil empfunden, daß die Plattenzylinder beim Anhalten der Maschine nicht immer eine solche Stellung einnehmen, daß die Platten ausgewechselt werden können. Zur Erzielung der richtigen Plattenstellung ist ein Drehen der Maschine von Hand oder ein meist mehrfaches Ein- und Ausschalten des Nebenmotors notwendig.In rotary printing presses, it is felt to be a disadvantage that the plate cylinder when stopping the machine do not always take up such a position that the plates can be exchanged. To achieve the correct plate position is a Turning the machine by hand or usually switching the auxiliary motor on and off several times necessary.
ίο Um diesem Übelstand abzuhelfen, wird gemäß der Erfindung die Maschine mit Mitteln ausgerüstet, die beim Anhalten der Maschine die Plattenzylinder in einer Winkelstellung zum Stillstand bringen, in v/elcher ein Plattenwechsel ohne weitere Drehung möglich ist. Zweckmäßig geschieht dies durch synchron mit den Plattenzylindern sich bewegende Schalter, die durch Drudkknöpfe o. dgl. in den Stromkreis des Motors geschaltet werdenίο In order to remedy this evil, according to of the invention, the machine is equipped with means that stop the machine Bring the plate cylinder to a standstill in one angular position, in v / elcher a plate change is possible without further rotation. This is expediently done by moving synchronously with the plate cylinders Switches that are switched into the motor circuit by push buttons or the like
ao und die Stromverbindung für den Motor so lange aufrechterhalten, bis die Plattenzylinder eine entsprechende Winkellage erreicht haben. Auf der Zeichnung ist der Einfachheit halber die Einrichtung für eine Rotationsdruckmaschine mit nur zwei Druckwerken beispielsweise schematiscli veranschaulicht.ao and the power connection for the motor like that Maintain a long time until the plate cylinder have reached a corresponding angular position. For the sake of simplicity, the drawing shows the device for a rotary printing press schematically illustrated with only two printing units, for example.
Mit den Plattenzylindern der auf der Zeichnung nicht dargestellten Rotationsdruckmaschine dreht sich eine die Schaltsegmentea,b tragende Welle 0, die an den einen Pol der Stromquelle über Druckknöpfe d, e angeschlossen werden kann. In gewissen Winkelstellungen werden die Segmente a, b mit dem anderen Pol der Stromquelle durch Bürsten /, g· verbunden. In den Stromkreis der Schaltsegmente α und & kann der die Drackmaschine antreibende Motor h mittels des Umschalters/ eingeschaltet werden.With the plate cylinders of the rotary printing press, not shown in the drawing, a shaft 0 carrying the switching segments a, b rotates and can be connected to one pole of the power source via push buttons d, e. In certain angular positions, the segments a, b are connected to the other pole of the power source by brushes /, g ·. The motor h driving the printing machine can be switched on in the circuit of the switching segments α and & by means of the switch /.
Preßt man nach entsprechender Einstellung des Umschalters / den Druckknopf d ein, so dreht sich der Motor h so lange, bis das Schaltsegment α nicht mehr mit der Bürste / in Berührung steht. Alsdann steht die Maschine still, und zwar in. der durch die Länge des Schaltsegmentes α bestimmten Winkelstellung. Nach Fertigstellung der Arbeiten kann man durch Pressen auf den Knopf e die Plattenzylinder in die Winkelstellung bringen lassen, in welcher die andere Plattenreihe leicht zugänglich ist. If you press the pushbutton d after setting the switch / button, the motor h rotates until the switching segment α is no longer in contact with the brush /. The machine then comes to a standstill, specifically in the angular position determined by the length of the switching segment α. After the work has been completed, the plate cylinder can be brought into the angular position in which the other row of plates is easily accessible by pressing button e.
Die Druckknöpfe d, e können mit Magnethemmung versehen sein, so daß sie in der eingeschalteten Lage bleiben, bis der Stromkreis durch das Schaltsegment α bzw. b unterbrochen wird.The push buttons d, e can be provided with magnetic lock so that they remain in the switched-on position until the circuit is interrupted by the switching segment α or b .
