Description
Die Erfindung .betrifft die zwangsläufige Steuerung der Druckzylindiergreifer durch eine schwenkbar gesteuerte Kurve, die eine stoßfreie Annahme und Abgabe der Bogen bei taktmäßig sich hebendem Zylinderbewirkt.The invention relates to the inevitable control of the pressure cylinder grippers by a swiveling controlled curve, which allows a smooth acceptance and delivery of the Arch caused when the cylinder rises in rhythm.
Bisher wurden die Druckzylirndiergreifer :durch zwei Kurven gesteuert, die an der Seitenwand oder Masnhine gelagert waren und zusätzlich durch einen Exzenter seitlich bewegt wurden. Diese Ausr Führung hat den Nachteil, daß die seitliche Steuerung der breiten Kurvenstücke mit schmalem Fuß leicht zu Klemmungen führt. Es sind auch Ausführungen bekannt, bei denen die Kurven gemeinsam mit -dem Druckzylinder gehaben und gesenkt werden, wie es d'ie Patentschrift 700 863 angibt: Sie haben aber auch den gleichen Nachteil, daß die Kurven durch die seitliche Bewegung ungünstig beansprucht werden.Up to now the pressure cylinder grippers were: controlled by two curves, which were mounted on the side wall or Masnhine and additionally by an eccentric moved sideways. This version has the disadvantage that the lateral steering the wide curve pieces with a narrow foot easily lead to jamming. There are too Designs known in which the curves have shared with the pressure cylinder and be lowered, as the patent specification 700 863 indicates: But you also have the same disadvantage that the curves are unfavorably stressed by the lateral movement will.
Die vorliegende Erfindung vermeidet diese Nachteile. Sie besteht im wesentlichen darin, daß eine um einer. Bolzen schwenkbare Kurve, die durch einen Exzenter bewegt wird, die Steuerung der Druckzylindergreifer und die von demExzenter abgeleitete Bewegung über eine Welle mit Hebel und Zahnsegment durch Rollen mittels 'eines schwenkbaren Ringes auf die Greiferkurve überträgt. Dadurch steuert die Kurve in der ersten Umdrehung hei gehobenem Zylinder die Bogenannahme, bei der zweiten Umdrehung bei gehobenem Zylinder die Bogenabgabe. Die Unterseite der Kurve ist am Eingang und Ausgang der Bewegung tangential zur Bewegungsrichtung der Rollen ausgebildet, damit die Kurve während der Steuerung -der Druckzylindergreifer und beim Heben des Zylinders in. ihrer Lage unbeweglich verharrt.The present invention avoids these disadvantages. It consists in essential in the fact that one around one. Bolt swiveling curve through a Eccentric is moved, the control of the printing cylinder gripper and that of the eccentric derived movement via a shaft with lever and toothed segment by means of rollers 'A pivotable ring transfers to the gripper curve. This controls the curve in the first revolution with the cylinder raised the sheet acceptance, in the second Rotation with the cylinder raised. The bottom of the curve is on The input and output of the movement are tangential to the direction of movement of the rollers, so that the curve during the control -the pressure cylinder gripper and when lifting the Cylinder remains immobile in its position.
In der Zeichnung ist die Erfindung'beispielsweise dargestellt, und zwar zeigt Abb. i einem. Schnitt, Abb.@ 2 eine Ansicht des Exzenters mit Welle urd Hebel, Abb. 3 eine Ansicht des Rollenringes mit Kurve und Zähnsegmenten: Der auf einer Büchse i der Druokzylinderaahse 2 taufende und über ein Zahnradgetriebe mit halber Druckzylindergeschwindigkeit angetriebene Exzenter 3 leitet d'ie Bewegung zur Steuerung der Druckzylindergreifer über eine mit Hebel 4 und 'Zahnsegment 5 versehene Welle 6, die in der ver-,1-ängerten :Seitenwandbüchse 7 gelagert ist, durch den Eingriff in ein Zahnsegment 8 und Rollen i t des schwenkbaren Ringes 9, der auf einer in der Seitenwand befestigten Büchse io gelagert.ist, auf die Kurve 12, die in einem Bolzen 13 drehbar gelagert ist, so daß.die Greifer bei gehobenem Druckzylinder-in, der 'Bersten Umdrehung den Bogen abnehmen und beider zweiten Zylinderumdrehung bei gehobenem Druckzylinder den Bogen abgeben.In the drawing, the invention is shown, for example, and although Fig. i shows one. Section, Fig. @ 2 a view of the eccentric with shaft and Lever, Fig. 3 a view of the roller ring with curve and tooth segments: The on a sleeve i of the Druokylinderaahse 2 baptismal and via a gear drive with eccentric 3 driven half the printing cylinder speed directs the movement to control the printing cylinder gripper via a lever 4 and toothed segment 5 provided shaft 6, which is mounted in the extended, 1-extended: side wall bushing 7, by engaging a toothed segment 8 and rollers i t of the pivotable ring 9, which is mounted on a bushing fixed in the side wall, onto the curve 12, which is rotatably mounted in a bolt 13, so that.die gripper when raised Impression cylinder-in, remove the sheet from the 'bursting turn and the second cylinder turn Deliver the sheet with the impression cylinder raised.
