Abstract
Description
Die Erfindung bezieht sich auf eine Rotations-Bogendruckmaschine für Schön- und Widerdruck mit einer Wendetrommel zwischen Druckzylindern doppelt großen Durchmessers zweier aufeinanderfolgender Druckwerke nach dem Oberbegriff des Patentanspruches 1.The invention relates to a rotary sheet-fed printing press for perfecting with a reversing drum between printing cylinders of double-large diameter two successive printing units according to the preamble of claim 1.
Eine solche Rotations-Bogendruckmaschine ist aus JP-SHO 3-12517 bekannt. Danach wird der Bogen an seiner Vorderkante von an dem Druckzylinder beweglich angeordneten und im Arbeitstakt der Maschine gesteuerten Klemmgreifern erfaßt und auf ganzer Länge an dem übergabepunkt vorbeigezogen, an dem der Bogen an die Wendetrommel übergeben wird, wobei an der Wendetrommel beweglich angeordnete Zangengreifer den Bogen an seiner Hinterkante erfassen, so daß der Bogen nunmehr mit seiner Hinterkante voraus um die Wendetrommel herumgeführt wird. Dabei stellt die registerhaltige Bogenübergabe ein sehr schwieriges Problem dar, weil dazu eine Bogenglättung auf dem als Speichertrommel fungierenden Druckzylinder erforderlich wäre. Mit bekannten Einrichtungen ist dies jedoch wegen der erforderlichen Mittel zur formateinstellung am Druckzylinder nicht erreichbar.Such a rotary sheet printing machine is known from JP-SHO 3-12517. The sheet is then gripped on its leading edge by clamping grippers which are movably arranged on the printing cylinder and controlled in the work cycle of the machine, and is pulled along the entire length at the transfer point at which the sheet is transferred to the reversing drum, with pliers grippers movably arranged on the reversing drum grasp its trailing edge, so that the sheet is now led with its trailing edge ahead around the turning drum. The register-based sheet transfer represents a very difficult problem because it would require smoothing of the sheet on the printing cylinder that functions as a storage drum. With known devices, however, this cannot be achieved because of the necessary means for setting the format on the printing cylinder.
Aus der DE 30 50 295 ist die Anordnung von in Umfangsrichtung und in Achsrichtung einer einfachen Umführtrommel bewegliche Saugdüsen bekannt, die den Bogen im hinteren Bereich zum Zwecke der seitlichen und peripheren Bogenglättung ansaugen. Aus der DE 24 52 096 sind für den gleichen Zweck in einer Umführtrommel Drehsauger mit einer asymmetrisch angeordneten Saugöffnung vorgesehen, so daß eine Drehbewegung der Drehsauger zu einer Glättung des in Nähe seiner Hinterkante angesaugten und an der Vorderkante in einem Greifersystem gehaltenen Bogens in seitlicher Richtung und in Umfangsrichtung führt. In dieser Druckschrift sind auch mehrere Drehsauger in einer Reihe quer zur Maschinenlängsmitte nebeneinander und mit einem von der Maschinenlängsmitte nach außen größer werdenden Drehwinkel offenbart. Vergleichbare Anordnungen sind auch in der DE 30 36 790 C2 beschrieben.From DE 30 50 295 the arrangement of suction nozzles movable in the circumferential direction and in the axial direction of a simple transfer drum is known, which suck the sheet in the rear area for the purpose of lateral and peripheral sheet smoothing. From DE 24 52 096 rotary vacuum cleaners with an asymmetrically arranged suction opening are provided for the same purpose in a transfer drum, so that a rotary movement of the rotary vacuum cleaners to smooth the suction near its rear edge and at the front edge in a gripper system held arc in the lateral direction and in the circumferential direction. This publication also discloses a plurality of rotary suction cups in a row transversely to the machine longitudinal center next to one another and with an angle of rotation that increases from the machine longitudinal center to the outside. Comparable arrangements are also described in DE 30 36 790 C2.
Der Erfindung liegt die Aufgabe zugrunde, bei einer Rotations-Bogendruckmaschine für den Schön- und Widerdruck mit einer Wendetrommel zwischen doppelt großen Druckzylindern zweier aufeinanderfolgender Druckwerke eine registerhaltige Bogenübergabe von dem als Speichertrommel wirkenden Druckzylinder des in Bogenlaufrichtung vorderen Druckwerks an die Wendetrommel bei der Bogenwendung zu erreichen.The invention is based on the object of achieving a register-oriented sheet transfer from the printing cylinder acting as a storage drum of the front printing unit in the direction of sheet travel to the turning drum when the sheet is turned in a rotary sheet-fed printing machine for perfecting with a reversing drum between double-sized printing cylinders of two successive printing units .
Die Erfindung löst diese Aufgabe durch eine Ausbildung mit den Merkmalen nach dem Kennzeichen des Patentanspruches 1.The invention solves this problem by training with the features according to the characterizing part of patent claim 1.
Durch diese Saugdüsen in der Wendetrommel wird das hintere Ende des am übergabepunkt zur Wendetrommel vorbeilaufenden, am Druckzylinder geführten und mit seiner Vorderkante in den Klemmgreifern des Druckzylinders gehaltenen Bogens angesaugt, wobei die Saugkräfte sowohl entgegen der Umlaufrichtung des Druckzylinders peripher als auch diagonal zur Seite wirksam sind, so daß der Bogen sowohl in Umfangsrichtung als auch in seitlicher Richtung geglättet wird, damit er glatt und eben an der Umfangsfläche des Druckzylinders anliegt, wenn die Zangengreifer der Wendetrommel die Bogenhinterkante erfassen. Da die Klemmgreifer des Druckzylinders den Bogen an seiner Vorderkante sicher halten, kann bei dieser Glättbewegung gegebenenfalls eine geringe Relativbewegung zwischen den Saugdüsen und dem in seinem hinteren Bereich gegen die Wendetrommel angesaugten Bogen erfolgen. Gleichzeitig wird durch die erfindungsgemäß vorgesehenen Saugdüsen eine größere Sicherheit bei der Bogenerfassung an seiner Hinterkante durch die Zangengreifer der Wendetromml erreicht, weil die Sauger in der Wendetrommel die Bogenhinterkante stets in eine genaue Position bringen, in der sie von den Zangengreifern der Wendetrommel erfaßt werden.Through these suction nozzles in the turning drum, the rear end of the sheet passing at the transfer point to the turning drum, guided on the printing cylinder and held with its front edge in the clamping grippers of the printing cylinder, is sucked in, the suction forces acting both counter to the circumferential direction of the printing cylinder, peripherally and diagonally to the side , so that the sheet is smoothed both in the circumferential direction and in the lateral direction so that it lies smoothly and evenly on the circumferential surface of the printing cylinder when the pliers grippers of the turning drum grip the trailing edge of the sheet. Since the clamping grippers of the impression cylinder hold the sheet securely on its front edge, a slight relative movement between the suction nozzles and the sheet sucked against the reversing drum in its rear region can possibly take place during this smoothing movement. At the same time, the suction nozzles provided according to the invention provide greater security in the sheet detection at its rear edge the pliers grippers of the turning drum reached because the suction cups in the turning drum always bring the trailing edge of the sheet into a precise position in which they are gripped by the pliers grippers of the turning drum.
Zur konstruktiven Verwirklichung des Erfindungsgedankens sind an sich bekannte Drehsauger mit asymmetrisch zur Drehachse liegender Saugöffnung geeignet, wie sie beispielsweise in der DE 24 52 096 beschrieben sind. Geeignet sind aber auch bekannte Anordnungen, zum Beispiel entsprechend der DE 30 36 790.For constructively realizing the inventive concept, known rotary suction cups with suction opening asymmetrical to the axis of rotation are suitable, as are described for example in DE 24 52 096. However, known arrangements are also suitable, for example in accordance with DE 30 36 790.
In weiterer Ausgestaltung der Erfindung können die in der Wendetrommel in der Nähe der Zangengreifer angeordneten Drehsauger quer zur Maschinenmitte mit einem Abstand nebeneinander und einem von der Maschinenmitte nach außen größer werdenden Drehwinkel zur Bogenglättung angeordnet sein.In a further embodiment of the invention, the rotary suction cups arranged in the turning drum in the vicinity of the pliers grippers can be arranged transversely to the machine center with a spacing next to one another and an angle of rotation that increases from the machine center outwards for smoothing the sheet.
Schließlich ist hervorzuheben, daß die Erfindungsmerkmale zu den gleichen Vorteilen der Bogenglättung führen, wenn die Wendetrommel lediglich als Umführtrommel beim Schöndruck verwendet wird.Finally, it should be emphasized that the features of the invention lead to the same advantages of sheet smoothing when the reversing drum is only used as a transfer drum for straight printing.
