[Aufgabe der Erfindung]OBJECT OF THE INVENTION

Der Erfindung liegt die Aufgabe zugrunde, eine Bogenleiteinrichtung der eingangs beschriebenen Art zu schaffen, die insbesondere auf einem Druckzylinder mit zugeordneter Druck-/ Lackierzone die glatte Auflage eines Bogens bereits ab einem dieser Druck-/Lackierzone vorgeordneten Übergabebereich gewährleistet und eine verbesserte Bogenführung entlang einer Führungsfläche der Bogenleiteinrichtung im Bogenaufgang vor dem Übergabebereich gestattet.The invention has for its object a sheet guiding device of the kind described in the introduction to create the in particular on a printing cylinder with an associated printing / Varnishing zone the smooth support of a sheet from one transfer area upstream of this printing / painting zone guaranteed and improved sheet guidance along a Guide surface of the sheet guiding device in front of the sheet emergence the transfer area allowed.

Die Aufgabe wird durch die Ausbildungsmerkmale der Ansprüche 1 und 2 gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen.The task is determined by the training characteristics of the claims 1 and 2 solved. Further training results from the subclaims.

Die Erfindung bezieht sich auf eine kammförmige Bogenleiteinrichtung mit einer pneumatisch beaufschlagbaren Führungsfläche, wobei diese dem Übergabebereich von zwei Greifersystemen zugeordnet ist. Die Greifersysteme sind dabei an je einem Bogenführungszylinder und/oder einem umlaufenden Kettensystem angeordnet.The invention relates to a comb-shaped sheet guiding device with a pneumatically actuated guide surface, this being the transfer area of two gripper systems assigned. The gripper systems are each on one Bow guide cylinder and / or a rotating chain system arranged.

Ein erster Vorteil der erfindungsgemäßen Bogenleiteinrichtung ist darin begründet, dass beispielsweise ein von einem Transferzylinder im Greiferschluß geführter Bogen auf seiner vorgegebenen Förderebene an das Greifersystem eines nachgeordneten Druckzylinders übergeben wird. Alternativ wird ein von einem Greifersystem eines umlaufenden Kettensystems geführter Bogen auf seiner vorgegebenen Förderebene an ein Greifersystem eines nachgeordneten Druckzylinders übergeben.A first advantage of the sheet guiding device according to the invention is based on the fact that, for example, one of a transfer cylinder bow guided in the gripper closure on his predetermined conveying level to the gripper system of a downstream one Printing cylinder is passed. Alternatively, a from a gripper system of a rotating chain system guided bow at its specified conveying level Transfer gripper system of a downstream printing cylinder.

Ein weiterer Vorteil der Ausbildung besteht darin, dass die Bogenleiteinrichtung erfindungsgemäß als kammförmige Bogenleiteinrichtung ausgebildet ist und deren Zinken - ohne Beschädigungen insbesondere im Bereich der Bogenhinterkante zu verursachen - im Bogenaufgang möglichst nahe in den Übergabebereich zweier Greifersysteme hineinragen. Die kammförmige Bogenleiteinrichtung erzeugt mittels eines zuschaltbaren, vorzugsweise regelbaren Pneumatiksystems eine Saugluftströmung. Die Saugluftströmung bildet unterhalb des Übergabebereiches zweier Greifersysteme ein Unterdruckgebiet aus, so dass der Bogen, bevorzugt ab dem Tangentenpunkt, glatt auf dem Druckzylinder aufliegt. Damit ist das zwischen dem Bogen und der Mantelfläche des Druckzylinders befindliche Luftpolster sowie die Umgebungsluft unterhalb des Übergabebereiches spürbar reduzierbar.Another advantage of training is that Sheet guiding device according to the invention as a comb-shaped sheet guiding device is trained and their tines - without Damage especially in the area of the trailing edge of the sheet cause - in the arch as close as possible to the transfer area two gripper systems protrude. The comb-shaped Sheet guiding device generated by means of a switchable preferably adjustable pneumatic system a suction air flow. The suction air flow forms below the transfer area two gripper systems from a vacuum area, so that the arc, preferably from the tangent point, opens smoothly rests on the impression cylinder. So that's between the arch and the outer surface of the pressure cylinder located air cushion as well as the ambient air below the transfer area noticeably reducible.

Eine zusätzliche Reduzierung von Umgebungsluft ist erzielbar, indem den Zinken der kammförmigen Bogenleiteinrichtung eine Saugleiste in Förderrichtung des Bogenmaterials vorgeordnet ist. Dabei ist die Saugleiste in eine vorgeordnete Bogenleiteinrichtung integriert oder am Ende dieser Bogenleiteinrichtung (in Förderrichtung vor der kammförmigen Bogenleiteinrichtung) anordenbar.An additional reduction in ambient air can be achieved by the prongs of the comb-shaped sheet guide Upstream suction bar in the conveying direction of the sheet material is. The squeegee is in an upstream sheet guiding device integrated or at the end of this sheet guide (in the conveying direction in front of the comb-shaped sheet guiding device) arranged.

Vorteilhaft ist ferner, dass in einem durch Druckzone (Druckzylinder und Gummituchzylinder bzw. Formzylinder) und Übergabebereich zweier Greifersysteme (Tangentenpunkt von beispielsweise bogenführenden Zylindern) definierten Kreisbogen vor der Druck-/Lackierzone des Druckzylinders eine pneumatisch oder mechanisch betreibbare, Bogenführungseinrichtung dem Druckzylinder zugeordnet ist. Damit wird die Führung des bereits glatt auf der Mantelfläche des Druckzylinders aufliegenden Bogens vor der Druck-/Lackierzone unterstützt.It is also advantageous that in a pressure zone (pressure cylinder and blanket cylinder or forme cylinder) and transfer area two gripper systems (tangent point of, for example arc-guiding cylinders) defined circular arc pneumatic in front of the printing / painting zone of the printing cylinder or mechanically operable sheet guiding device is assigned to the impression cylinder. This will lead the already lying flat on the surface of the impression cylinder Supported sheet before the printing / painting zone.
