Description

Die vorliegende Erfindung betrifft ein Eindruckwerk für eine Rollenrotationsdruckmaschine. Insbesondere betrifft die Erfindung eine Motor- und Getriebeanordnung zum Antreiben der Zylinder eines Eindruckwerks in unterschiedlichen Betriebsarten.The present invention relates to an impression unit for a web-fed rotary printing press. In particular, the invention relates to a motor and transmission arrangement for driving the Cylinder of an impression unit in different operating modes.

In einer Rollenrotations-Offsetdruckmaschine wird in der Regel eine Papierbahn durch eine Vielzahl von Gummi-Gummi-Druckwerken geführt, in denen beide Seiten der Bahn mit einem mehrfarbigen Bild bedruckt werden.In a web-fed rotary offset printing machine, a paper web is usually replaced by one Variety of rubber-rubber printing units, in which both sides of the web with be printed on a multicolored image.

Im Akzidenz-, Zeitschriften- oder Zeitungsdruck ist es dabei oft vorteilhaft, wenn eine oder mehrere auf dem Plattenzylinder angeordnete Druckplatten ausgewechselt werden können, ohne dabei den Fortdruck zu unterbrechen. Ein Wechseln der Druckplatten kann z. B. dann nötig sein, wenn während eines Zeitungsproduktionslaufs die neuesten Nachrichten eingefügt werden und auf die Titelseite der laufenden Ausgabe gedruckt werden sollen oder wenn in verschiedenen Gebieten verschiedene Ausgaben derselben Zeitung unter verschiedenen Namen verteilt werden, so daß der Zeitungskopf während des Produktionslaufs geändert werden muß.In commercial, magazine or newspaper printing, it is often advantageous if one or several printing plates arranged on the plate cylinder can be exchanged, without interrupting printing. Changing the printing plates can e.g. B. then necessary if the latest news during a newspaper production run should be inserted and printed on the front page of the current issue or if in different areas different editions of the same newspaper under different names can be distributed so that the newspaper head during the Production run must be changed.

Die EP-A-0 820 861 beschreibt eine Druckeinheit einer Offset-Rotationsdruckmaschine mit zwei Paaren von Platten- und Gummituchzylindern, von denen der erste Plattenzylinder und die beiden Gummituchzylinder mechanisch über verschiebbare Zahnräder gekoppelt und von einem gemeinsamen Antrieb angetrieben werden. Der zweite Plattenzylinder ist mit einem eigenen Antrieb versehen.EP-A-0 820 861 describes a printing unit of an offset rotary printing press two pairs of plate and blanket cylinders, of which the first plate cylinder and the two blanket cylinders mechanically coupled via sliding gears and are driven by a common drive. The second plate cylinder is with provided with its own drive.

Die DE-C 35 10 822 beschreibt ein Druckwerk einer Rollenrotationsdruckmaschine, bei dem ein gemeinsamer Gegendruckzylinder als Papierleitwalze dient und von den beiden Gummituchzylindern getrennt ist. Beim Einsatz des Druckwerks als ein einzelnes Druckwerk wird das obere Plattenzylinder-Gummituchzylinderpaar oder das untere Plattenzylinder-Gummituchzylinderpaar über verschiebbare Zahnräder mit dem gemeinsamen Gegendruckzylinder verbunden und das jeweils nicht angestellte Zylinderpaar zur Durchführung eines fliegenden Plattenwechsels stillgesetzt.DE-C 35 10 822 describes a printing unit of a web-fed rotary printing press in which a common impression cylinder serves as a paper guide roller and from the two Blanket cylinders is separated. When using the printing unit as a single Printing unit becomes the upper pair of plate cylinders and blankets or the lower one Plate cylinder rubber blanket cylinder pair with sliding gears with the common Counter pressure cylinder connected and the respective non-employed pair of cylinders Performing a flying plate change stopped.

In GB 2 309 668 wird ein Gummi-Gummi-Druckwerk offengelegt, das einen fliegenden Plattenwechsel ermöglicht, wobei die Plattenzylinder in Rollkontakt zu der sich bewegenden Bahn bleiben, während die Gummituchzylinder des Druckwerks jeweils abwechselnd an den zugeordneten Gummituchzylinder an- bzw. von diesem abgestellt werden. Die Gummituchzylinder sind über ineinander greifende Zahnräder, z. B. Stirnräder, permanent miteinander gekoppelt und werden über eine Längswelle von dem Hauptantriebsmotor der Druckmaschine angetrieben. Die Gummituchzylinder sind jedoch über Kupplungen bzw. ihnen zugeordnete weitere Zahnräder an die Zahnräder der Gummituchzylinder gekoppelt. Zum Wechseln der Druckplatten auf einem der Plattenzylinder während des Fortdruckbetriebs wird die Antriebsverbindung des Plattenzylinders unterbrochen, indem die entsprechende Kupplung aktiviert wird, und der Plattenzylinder wird von einem Hilfsmotor abgebremst. Nach dem Plattenwechsel wird der Plattenzylinder von dem Hilfsmotor wieder auf Druckgeschwindigkeit beschleunigt, bevor er an den ihm zugeordneten Gummituchzylinder angestellt wird. Neben der Längswelle und dem Hauptantriebsmotor sind demgemäß zur Durchführung eines fliegenden Plattenwechsels mindestens zwei Hilfsmotoren nötig. Darüber hinaus ist das Druckwerk kompliziert aufgebaut und anfällig für durch Torsionsschwingungen hervorgerufene Störungen in dem Getriebezug, über den die Zylinder angetrieben werden.GB 2 309 668 discloses a rubber-to-rubber printing unit that has a flying one Plate change allows, with the plate cylinder in rolling contact with the moving Web remain, while the blanket cylinders of the printing unit alternately on the assigned blanket cylinder on or off this. The Blanket cylinders are over interlocking gears, z. B. spur gears, permanent coupled with each other and are via a longitudinal shaft of the main drive motor Printing press driven. The rubber blanket cylinders are however over couplings or further gears assigned to them are coupled to the gears of the blanket cylinders. To change the printing plates on one of the plate cylinders during the In printing operation, the drive connection of the plate cylinder is interrupted by the corresponding clutch is activated, and the plate cylinder is powered by an auxiliary motor braked. After changing the plate, the plate cylinder is replaced by the auxiliary motor accelerated to print speed before moving on to its assigned Blanket cylinder is started. In addition to the longitudinal shaft and the main drive motor are accordingly at least two for performing a flying plate change Auxiliary motors necessary. In addition, the printing unit is complicated and fragile for disturbances in the gear train caused by torsional vibrations the cylinders are driven.
