Description

Kurbelgreifer Zusatz zuiit Patent 625 548 Die Erfindung betrifft eine weitere Verbesserung eines Kurbelgreifers nach Anspruch i des Patents 625 548; sie besteht darin, daß das Gleitlager für den Greiferarm auf einem schwingenden Rahmen befestigt ist, der durch einen auf der Kurbelwelle sitzenden Herzexzenter gesteuert wird. Dadurch, daß der Schwingrahmen einerseits am Herzexzenter, anderseits am Gleitlager unmittelbar angreift, wird der bisher zur Steuerung des Gleitlagers erforderliche Zwischenhebel entbehrlich.Crank gripper addendum to patent 625 548 The invention relates to a further improvement of a crank gripper according to claim 1 of patent 625 548; it consists in that the slide bearing for the gripper arm is mounted on a swinging frame which is controlled by a heart eccentric located on the crankshaft. The fact that the oscillating frame acts directly on the one hand on the heart eccentric and on the other hand on the slide bearing means that the intermediate lever previously required to control the slide bearing can be dispensed with.

In der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes beispielsweise dargestellt, und zwar zeigt Abb. i eine Seitenansicht und Abb.2 eine Draufsicht auf den Greifer. Der Greiferarm i ist am einen Ende zu Greiferzähnen 2 ausgebildet und am anderen Ende am Kurbelzapfen 3 gelagert. Die Kurbelscheibe 4 sitzt auf der Kurbelwelle 5, auf der auch der Herzexzenter 6 angeordnet ist. Der Herzexzenter 6 wird von den Lappen 7Q des Greiferrahmens 7 umgriffen. Der Greiferrahmen ; ist einerseits um den Zapfe n8 schwingbar gelagert und steht anderseits durch das Gleitlager g mit dem Greiferarm i in gleitender Verbindung. Bei Drehung der Kurbelwelle 5 wird der den Herzexzenter 6 umgebende Rahmen 7 und damit das Gleitlager g in schwingende Bewegung versetzt, während der Greiferarm i durch den Kurbelzapfen 3 an seinem hinteren Ende eine Drehbewegung erhält. Durch trberlagerung der schwingenden Bewegung des Greiferklötzchens im Gleitlager 9 und der Drehbewegung der den Greiferarm i antreibenden Kurbelscheibe 4 führen die Greiferspitzen die zur Filmschaltung erforderliche Bewegung aus.In the drawing is an embodiment of the subject matter of the invention For example shown, namely Fig. i shows a side view and Fig.2 shows a Top view of the gripper. The gripper arm i is at one end to gripper teeth 2 and mounted on the crank pin 3 at the other end. The crank disc 4 sits on the crankshaft 5, on which the heart eccentric 6 is also arranged. Of the Heart eccentric 6 is encompassed by the tabs 7Q of the gripper frame 7. The gripper frame ; is on the one hand mounted to swing around the pin n8 and on the other hand stands through the slide bearing g with the gripper arm i in a sliding connection. When rotating the The crankshaft 5 becomes the frame 7 surrounding the heart eccentric 6 and thus the sliding bearing g set in oscillating motion, while the gripper arm i is driven by the crank pin 3 receives a rotary movement at its rear end. By superimposing the vibrating Movement of the gripper block in the plain bearing 9 and the rotational movement of the gripper arm i driving crank disk 4, the hook tips guide the required for film switching Movement off.
