Description

Bei der den Gegenstand des Hauptpatents bildenden Vorrichtung zum selbsttätigen Einschießen von Schutzbogen an Rotationsdruckmaschinen oder Schnellpressen sind mit Doppelgreifern ausgerüstete Förderbänder vorhanden, die die einem Stapel entnommenen Schutzbogen zusammen mit den jeweils in der Druckmaschine bedruckten Bogen ablegen. Dabei erfolgt die Übergabe der bedruckten Bogen an die mit den Doppelgreifern versehenen Förderbänder durch Zwischenfördermittel, z. B. Schwinggreifer oder umlaufende Sauger. Diese bewegen sich auf Kreisbahnen, wogegen sich die Doppelgreifer wegen der Anordnung an den Förderbändern geradlinig über den Stapel bewegen. Infolgedessen hängen die jeweils abzulegenden Bogen mit dem hinteren Ende nach unten durch und schleifen unter Umständen auf dem zuletzt abgelegten oberen Bogen des Stapels. Das wird mit der Erfindung dadurch vermieden, daß die Übergabe der bedruckten Bogen von den Auslegerkettengreifern an den freien Greifer des Greiferpaares durch Sauger oder Greifer bewirkt wird, die von zwischen den beiden Übergabestellen geradlinig geführten Ketten getragen werden.When the subject of the main patent forming device for automatic sighting of protective sheets on rotary printing machines or high-speed presses are with double grippers Equipped conveyor belts are available, which carry the protective sheets removed from a stack together with the respective in put down the printed sheet on the press. The printed ones are then handed over Arch to the conveyor belts provided with the double grippers by means of intermediate conveyors, z. B. vibrating grippers or rotating suction cups. These are moving on Circular paths, whereas the double grippers are because of the arrangement on the conveyor belts move in a straight line across the stack. As a result, the ones to be dropped depend on each one Arch with the back end down and possibly sand on the the top sheet of the pile that was deposited last. This is avoided with the invention by that the transfer of the printed sheets from the delivery chain grippers to the free gripper of the pair of grippers is effected by suction cups or grippers, which are from between the two transfer points in a straight line Chains are worn.

Auf der Zeichnung ist ein Ausführungsbeispiel dargestellt, wobei Sauger als Übermittlungsglieder vorgesehen sind.An exemplary embodiment is shown in the drawing, with suction devices as transmission links are provided.

Der von der Druckmaschine kommende, von den Greifern 15 gefaßte gute Bogen wird in der Bewegung von den an dem ebenfalls dauernd umlaufenden, über die Kettenräder 41, 42 geführten Kettensystem 43 vorhandenen Saugern 44 übernommen, wobei die Greifer 15, beeinflußt durch die Kurve 16, geöffnet werden. Wenn die Saugdüsen 44 die mit 44" gekennzeichnete Stellung erreicht haben, also den guten Bogen 14 in seiner bisherigen Richtung weitergebracht haben, befindet sich der

auf dem nächsten Stück Weg die Bogenvorderkante ins Greifermaul eingeführt ist, wenn durch Abgleiten der Rolle 45 an der Öffnerkurve 46 der Greiferfinger 13* sich schließt. Gleichzeitig wird mit an sich bekannten und wegen der Klarhaltung der Zeichnung nicht dargestellten Mitteln das Vakuum an den Saugdüsen unterbrochen. Das Greifersystem 13« hat gemäß dem Hauptpatent den Makulaturbogen 10 mitgebracht und wandern nun guter und Makulaturbogen gemeinsam der Ablagestelle zu.on the next part of the way the leading edge of the sheet is inserted into the gripper mouth, if by sliding the roller 45 on the opening cam 46 of the gripper fingers 13 * closes. At the same time is known per se and because of the clarity of the Drawing not shown means interrupted the vacuum at the suction nozzles. That Gripper system 13 «has according to the main patent Brought the waste sheet 10 and are now moving good and waste sheets together to the storage location.

Damit die Düsen 44 immer der Arbeitsseite zugekehrt sind, wird das Saugrohr 47 gesteuert durch die Schiene 48, deren am freien Ende sitzende Rolle 49 in der Nut 5.0 abrollt.So that the nozzles 44 are always facing the working side, the suction pipe 47 is controlled through the rail 48, the roller 49 of which is seated at the free end and rolls in the groove 5.0.

An Stelle der Sauger können auch Greifer oder ähnliche Klemmen verwendet werden.Instead of the suction cups, grippers or similar clamps can also be used.
