Description
Die Erfindung bezieht sich auf einen Greifer für den Filmtransport mit zwischen zwei den Filmtransport' bewirkenden Umläufen eingefügtem Leerlauf, bei dem der die Greiferspitzen tragende Hebel an einem in Richtung der Eingriffsbewegung gesteuerten Schwinghebel gelagert ist. Die bekannten Greifer dieser Art besitzen den Nachteil, daß durch die kraftschlüssige Steuerung des Schwinghebels durch eine Kurvenscheibe, gegen die der Schwinghebel durch eine Feder gezogen wird, großer Verschleiß und damit starke Geräusche verursacht werden. Diese Nachteile lassen sich dadurch vermeiden, wenn man gemäß der Erfindung, das den Schwinghebel steuernde Exzenter in eine im Schwinghebel vorgesehene Nut, welche schräg zur Achse des Greiferhebels verläuft, eingreifen läßt. Durch den an sich bei Greifern anderer Konstruktion bekannten Verlauf der Nut schräg zur Greiferhebelachse erfolgt auch der Austritt des Greifers aus der Perforation des Filmbandes in sehr kurzer Zeit. Im folgenden ist ein Ausführungsbeispiel eines Greifers nach der Erfindung beschrieben und in der Zeichnung in Abb. 1 und 2 dargestellt. The invention relates to a gripper for film transport with between two the film transport 'causing revolutions inserted idle, in which the gripper tips bearing lever is mounted on a rocking lever controlled in the direction of the engagement movement. The known Grippers of this type have the disadvantage that due to the positive control of the Rocker arm by a cam, against which the rocker arm by a spring pulled, causing great wear and tear and thus loud noises. These Disadvantages can be avoided if, according to the invention, the Rocker arm controlling eccentric in a groove provided in the rocker arm, which is inclined runs to the axis of the gripper lever, can engage. By itself with the grippers of others The course of the groove, which is known in the construction, at an angle to the gripper lever axis, is also where the gripper emerges from the perforation of the film tape in a very short time. An embodiment of a gripper according to the invention is described below and shown in the drawing in Figs.
Der Greiferhebel 1, welcher durch das gegenüber der den Verschluß in an sich bekannter Weise tragenden Achse-3 mit doppelter Geschwindigkeit umlaufende Herzexzenter 2 in Laufrichtung des Films angetrieben wird, ist mit seinem dem Greiferzahn 4 gegenüberliegenden Ende bzw. der Schwingachse 5 an dem die Eingriffsbewegung steuernden Schwinghebel 6 gelagert. Der Schwinghebel 6, der seine Drehachse bei 8 besitzt, erhält seinen Antrieb durch das auf der Welle 3 sitzende Exzenter 7. Dasselbe greift in eine Schrägführung 9 des Schwinghebels 6. Im vorliegenden Falle kommt die Schrägführung zwischen Exzenter 2 und Schwingachse 5 zu liegen, wo'durch Raum in der Ausdehnung des Greifers senkrecht zum Film erspart wird.The gripper lever 1, which by the opposite of the closure in known per se Way supporting axis-3 with double speed revolving heart eccentric 2 is driven in the direction of travel of the film, is opposite to the gripper tooth 4 with its The end or the swing axis 5 is mounted on the swing lever 6 controlling the engagement movement. The rocker arm 6, which has its axis of rotation at 8, is driven by the one on shaft 3 seated eccentric 7. The same engages in an inclined guide 9 of the rocker arm 6. Im In the present case, the inclined guidance between the eccentric 2 and the swing axis 5 applies which saves space in the extension of the gripper perpendicular to the film.
