KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei lithographischen Rotationsmaschinen wird vielfach der gedruckte Bogen über die Auslegertrommel mittels Schnüre oder Bänder auf einen Auslegerrechen getragen und von diesem durch Umwenden auf dem Auslegetisch abgelegt. Hierbei wird der noch feuchte Druck von den Schnüren oder Bändern und den Auslegerstäben mehr oder weniger verschmiert, was sich besonders bei Bogen mit ίο ganz bedruckter Fläche unangenehm bemerkbar macht, und es ist oft unmöglich, empfindliche Arbeiten auf Maschinen mit Rechenausleger herzustellen.In rotary lithographic machines, the printed sheet is often over the Boom drum carried by means of cords or straps on a boom rake and from this is placed on the delivery table by turning it over. Here the still damp Pressure from the cords or ribbons and the boom bars more or less smeared, which is particularly noticeable in the case of sheets with ίο completely printed areas power, and it is often impossible to do delicate work on machines with a computer boom to manufacture.
Die Erfindung besteht darin, den Auslegerrechen und die dazugehörige Schnur- oder
Bandleitung ganz in Wegfall zu bringen und die Bogen so zu leiten, daß die bedruckte
Seite mit Stäben, Schnüren oder Bändern nicht in Berührung kommt und unverschmiert
mittels des bekannten, von einem endlosen Kettenpaar getragenen Greifersystems auf
• den Auslegetisch abgelegt wird.
In der Zeichnung zeigt:
Fig. ι eine Seitenansicht,The invention consists in completely eliminating the cantilever rake and the associated cord or ribbon line and to guide the arches so that the printed side does not come into contact with bars, cords or ribbons and is not smeared by means of the known, endless chain pair carried gripper system is placed on the delivery table.
In the drawing shows:
Fig. Ι a side view,
Fig. 2 einen Grundriß der gesamten Auslegevorrichtung. Fig. 2 is a plan view of the entire delivery device.
Der Vorgang des Auslegens der bedrucktenThe process of laying out the printed
Bogen spielt sich in folgender Weise ab.Arc plays out in the following way.
Der auf dem Druckzylinder α liegende Bogen wird von der Trommel b mittels Greifer übernommen und auf den schrägliegenden Schienen c nach unten geführt, bis die hintere Kante des Bogens an der Spitze der beweglichen Bogenführungskeile d vorbei ist. Die weitere Abwärtsbewegung wird durch die Anschläge e begrenzt. Die Rollen f drücken dann den Bogen an die in der Pfeilrichtung sich drehende Walze g, wodurch der Bogen unter den Führungskeilen d hindurch dem Greifersystem i, welches von einem parallel laufenden, endlosen Kettenpaar h getragen wird, zugeführt, von diesem erfaßt und in bekannter Weise auf den Auslegetisch k abgelegt wird.The sheet lying on the printing cylinder α is taken over by the drum b by means of a gripper and guided downward on the inclined rails c until the rear edge of the sheet is past the tip of the movable sheet guide wedges d . The further downward movement is limited by the stops e. The rollers f then press the sheet against the roller g rotating in the direction of the arrow, as a result of which the sheet is fed under the guide wedges d through the gripper system i, which is carried by a parallel, endless pair of chains h , is grasped by the latter and in a known manner is placed on the delivery table k .
