Description

Gewölbter Anlegetisch für automatische Bogenzuführungseinrichtung an Druck- und Papierverarbeitungsmaschinen Zur Förderung von Papierbogen zu Druck- oder Papierverarbeitungsmaschinen sind gewölbte Anlegetische bekannt, deren Wölbung in der Bogenförderrichtung zur Erhöhung der Eigensteifigkeit der Bogen bei ihrem durch seitliche Schiebemarken quer zur Förderrichtung erfolgenden Ausrichten dient. Arched feed table for automatic sheet feeder on printing and paper processing machines For conveying paper sheets to printing or paper processing machines, curved feed tables are known whose curvature in the sheet conveying direction to increase the rigidity of the sheets in their is used to align transversely to the conveying direction by means of lateral sliding marks.

Bei den bekannten Ausbildungen dieser Art ist der Anlegetisch konkav gewölbt. Diese Einwölbung bewirkt zwar eine Versteifung der zu fördernden Bogen beim Ausrichten durch Seitenmarken, doch läßt sich diese Ausbildung nicht für Anlegetische verwenden, über die die Bogen durch Zugfördermittel bewegt werden, da diese Zugfördermittel infolge der Spannung der sie tragenden Kette oder Bandes sich mit den Bogen von der eingewölbten Tischoberfläche abheben. In the known designs of this type, the feed table is concave arched. This bulge causes a stiffening of the sheet to be conveyed when aligning by side marks, but this training cannot be used for feed tables use, over which the sheets are moved by train conveyors, as these train conveyors as a result of the tension of the chain or belt that carries them, it is connected to the bow of the vaulted table surface.

Dieser Mangel wird nach der Erfindung dadurch ausgeräumt, daß bei einem gewölbten Anlegetisch für die automatische Bogenzuführeinrichtung an Druck-und Papierverarbeitungsmaschinen, dessen Wölbung in Bogenförderrichtung zur Erhöhung der Eigensteifigkeit der Bogen bei ihrem durch seitliche Schiebemarken quer zur Förderrichtung erfolgenden Ausrichten dient, bei an sich bekannter Verwendung von umlaufenden Zugfördermitteln für die Bogenzuführung der Anlegetisch in seiner ganzen Länge konvex ausgebildet ist. This deficiency is eliminated according to the invention in that at a curved feed table for the automatic sheet feeder to print and Paper processing machines, whose curvature in the sheet conveying direction to increase the inherent stiffness of the arches in their lateral sliding marks across the Alignment taking place in the conveying direction is used when using circulating traction conveyor for the sheet feeding of the feed table in its whole Length is convex.

Bei dieser Ausbildung folgen die die Fördermittel tragenden Ketten oder Bänder der Auswölbung des Tisches, so daß die Bogen nicht von diesem abgehoben werden. Bei der durch die konvexe Wölbung gesteuerten Anlage der Bogen und ihrer Förderorgane auf der ganzen Länge der Tischoberfläche erstreckt sich diese ununterbrochen zwischen dem Papierstapel und dem Druckzylinder, um die Bogen vom Stapel aus schon richtig dem Tisch zuführen zu können. In this training, the chains carrying the funds follow or tapes the bulge of the table so that the sheets are not lifted off it will. In the case of the arches and theirs controlled by the convex curvature Conveyor organs along the entire length of the table surface extends this uninterrupted between the paper stack and the impression cylinder in order to get the sheets from the stack already to be able to feed correctly to the table.

Die Erfindung ist nachstehend an Hand des in der Zeichnung dargestellten Staffelanlegers näher erläutert. The invention is illustrated below with reference to that shown in the drawing Graduated investor explained in more detail.

Zwischen dem Druckzylinder 1 und dem Bogenstapel 2 ist ein Anlegetisch 3 vorgesehen. Zum Fördern der Bogen über den Tisch 3 dient ein schrittweise umlaufendes Greifersystem, das aus mittels Ketten bewegten Greifern 4 besteht, die mittels Führungen 5 entlang dem Anlagetisch 3 und durch Schlitze in diesem hindurchgreifend in Pfeilrichtung 6 bewegt werden. Between the impression cylinder 1 and the stack of sheets 2 is a feed table 3 provided. For conveying the sheet over the table 3, a gradually circulating one is used Gripper system, which consists of grippers 4 moved by means of chains, which by means of guides 5 along the system table 3 and through slots in this reaching through in the direction of the arrow 6 can be moved.

Die Oberfläche des Tisches 3 ist über die ganze Tischlänge konvex ausgewölbt. Dabei folgen die Greifer4 der Auswölbung, so daß die Bogen nicht von der Tischfiäche abgehoben und ausgewölbt über diesen gefördert werden. Diese Auswölbung der Tischfläche, der die Bogen folgen, führt zu einer Erhöhung der Eigensteifigkeit der Bogen quer zu ihrer Förderrichtung und damit zu einer Erhöhung ihres Widerstandes beim Ausrichten mittels der seitlichen Anlegemarken 10. Zufolge dieser erhöhten Eigensteifigkeit können auch sehr dünne und große Bogen selbst bei höheren Laufgeschwindigkeiten sicher ausgerichtet werden. The surface of the table 3 is convex over the entire length of the table bulging. The grippers4 follow the bulge so that the arches do not move from lifted off the table surface and arched over it. This bulge the The table surface, which the arches follow, increases the inherent rigidity the sheet transversely to its conveying direction and thus to an increase in its resistance when aligning by means of the lateral positioning marks 10. As a result of these increased Intrinsic rigidity can also create very thin and large sheets even at higher running speeds be safely aligned.

Die Übergabe der Bogen b an die Greifer erfolgt in bekannter Weise durch Anhebeglieder 7. Der Abgabe der Bogen an den Druckzylinder 1 dienen schwingende Vorgreifer 8, die auch die beweglichen Vordermarken 9 tragen. The transfer of the sheet b to the gripper takes place in a known manner by lifting members 7. The delivery of the sheets to the impression cylinder 1 are vibrating Pre-grippers 8, which also carry the movable front lays 9.
