Description
Vorrichtung zum Bewegen des Bogenabhebers von Bogenanlegern mittels einer Kulisse Die Erfindung bezieht sich auf eine -weitere Ausbildung .der durch das Patent 454 864 bekannt gewordenen Vorrichtung zum Bewegen des Bogenabhebers von Bogenanlegern mittels einer Kulisse.Device for moving the sheet lifter from sheet feeders by means of a backdrop The invention relates to a -further training .der by the patent 454 864 has become known device for moving the sheet lifter of sheet feeders by means of a backdrop.
Die Erfindung besteht im wesentlichen darin, daß die Kulissenbewegung durch ein Zahnsegmentpaar auf das Gestänge des Bogenabhebers übertragen wird.The invention consists essentially in the fact that the link movement is transferred to the linkage of the sheet lifter by a pair of toothed segments.
Dadurch ergibt sich der Vorteil, daß man durch geeignete Wahl der Übersetzung leicht jeden gewünschten Ausschlag des Gestänges erzielen kann.This has the advantage that by suitable choice of the Translation can easily achieve any desired deflection of the linkage.
Auf der Zeichnung ist die Erfindung an zwei Ausführungsbeispielen veranschaulicht. Bei der ersten Ausführungsform (Abb. i ) ist -das eine Zahnsegment Z1 auf der ortsfesten Welle in gelagert, die gleichzeitig die Kulisse u aufnimmt, die mittels einer Kurbel von der Welle h aus in Gang gesetzt wird, und in deren Schlitz a der Stein t gleitet. Das andere Zahnsegment Z= ist auf der ortsfesten Welle d gelagert, die bleichzeitig den Hebel v aufnimmt. Durch einen Bolzen eist -der Hebel v an eine Stange f angelenkt, .die an ihrem freien Ende den Bogenabheber h trägt. Die Stange l hat einen Schlitz s, in dem ein Bolzen p verschiebbar ist. Ein Lenker f, an dessen freiem Ende der Bolzen p befestigt ist, ist auf einer ortsfesten Welle- gelagert und wird ,durch eine Feder iz gegen einen Anschlag q gezogen. Die abzuführenden Bogen g liegen gegen den .Anschlag z des Stapeltisches. Zur Übernahme und Weiterleitung der Bogen dienen die um den Punkt r schwenkbaren Abnahmerollen y, die mit den Förderrollen o zusammenarbeiten.The invention is illustrated in two exemplary embodiments in the drawing. In the first embodiment (Fig. I) one gear segment Z1 is mounted on the stationary shaft in, which at the same time accommodates the link u, which is set in motion by a crank from the shaft h, and in its slot a the stone t slides. The other tooth segment Z = is mounted on the stationary shaft d, which at the same time picks up the lever v. The lever v is linked to a rod f by a bolt e , which carries the sheet lifter h at its free end. The rod l has a slot s in which a bolt p can be displaced. A link f, at the free end of which the bolt p is attached, is mounted on a stationary shaft and is pulled against a stop q by a spring iz. The sheets g to be removed lie against the .Anschlag z of the stacking table. The take-off rollers y, which can be pivoted about point r and work together with the conveyor rollers o, serve to take over and forward the sheets.
Bei dem zweiten Beispiel (Abb.2) ist das mit dem wiederum auf der Kulissenwelle nz angeordneten Zahnsegment Z' kämmende Zahnsegment Z2 auf der ortsfesten Welle i. des Lenkers f gelagert, der durch einen Bolzen p' mit der Saugertragstange L' verbunden ist.In the second example (Fig.2) it is again on the Link shaft nz arranged tooth segment Z 'meshing tooth segment Z2 on the stationary Wave i. of the handlebar f supported by a bolt p 'with the suction support rod L 'is connected.
Bei dieser Ausführung kommen also insbesondere der Schlitz s sowie die Feder n (Abb. i) in Fortfall, wodurch eine völlig formschlüssige, stoß- und schwingungsfreie Bewegung,des Saugers gewährleistet ist. Außerdem bietet diese Ausführung gegenüber dem Beispiel nach Abb. i .auch noch den Vorteil, daß sich mit Leichtigkeit eine ausreichend weite Einführung des Bogens auf die Walze o erzielen läßt.In this embodiment, the slot s and the spring n (Fig. I) in particular are omitted, which ensures a completely form-fitting, shock-free and vibration-free movement of the suction cup. In addition, this embodiment also offers the advantage over the example according to Fig. I that a sufficiently wide introduction of the sheet onto the roller o can be achieved with ease.
