Description

Die Erfindung betrifft eine Bogenrotationsdruckmaschine in Reihenbauweise mit mindestens zwei Druckwerken, in denen jeweils der zu bedruckende Bogen durch einen Gegendruckzylinder an einem mit einem Plattenzylinder zusammenwirkenden Gummizylinder zur Aufbringung eines Schöndruckes vorbeigeführt wird, wobei bei Schön- und Widerdruck Bogen jeweils nur bei jeder zweiten Umdrehung der Druckzylinder dem ersten Druckwerk zugeführt werden (DE-A-3108806).The invention relates to a sheet-fed rotary printing press in a row design with at least two printing units, in each of which the sheet to be printed is guided past a blanket cylinder interacting with a plate cylinder for application of a face print by a counter-pressure cylinder, with sheet-fed printing only in every second rotation Printing cylinders are fed to the first printing unit (DE-A-3108806).

Eine ähnliche Maschine ist aus dem Fachbuch «Einführung in den Offsetdruck» von Wolfgang Walenski, Eggen-Fachbuchreihe, Seite 114, bekannt. Bekanntlich ist es mit derartigen Druckmaschinen nur möglich, einen Widerdruck aufzubringen, indem zwischen zwei benachbarten Druckwerken Wendetrommeln eingesetzt werden, was zwangsläufig zu hohem Herstellungsaufwand und entsprechendem Platzbedarf führt.A similar machine is known from the specialist book “Introduction to offset printing” by Wolfgang Walenski, Eggen specialist book series, page 114. As is known, it is only possible with such printing machines to apply a counterpressure by using reversing drums between two adjacent printing units, which inevitably leads to high production costs and corresponding space requirements.

Aufgabe der Erfindung ist es, eine Bogenrotationsdruckmaschine der eingangs bezeichneten Art ohne zusätzliche Raumbeanspruchung und ohne Wendevorrichtungen wahlweise im Bedarfsfall auf Widerdruck umschaltbar auszugestalten.The object of the invention is to design a sheet-fed rotary printing press of the type mentioned at the outset to be switchable to back pressure, if required, without additional space and without turning devices.

Diese Aufgabe wird durch die Anwendung der Merkmale des kennzeichnenden Teiles des Patentanspruches gelöst. Die Erfindung wird im folgenden anhand eines Ausführungsbeispieles im einzelnen erläutert, wobei Bezug auf die beiliegenden Zeichnungen genommen wird. In diesen zeigenThis object is achieved by applying the features of the characterizing part of the patent claim. The invention is explained in detail below using an exemplary embodiment, reference being made to the accompanying drawings. Show in these

Fig. 1 bis 3 die erfindungsgemässe Bogenrotationsdruckmaschine in Reihenbauweise.1 to 3 the sheet-fed rotary printing press according to the invention in a row construction.

Die Figuren 1 bis 3 lassen die verschiedenen Positionen der zu bedruckenden Bogen in der Maschine erkennen. Eine Bogenrotationsdruckmaschine umfasst hier vier Druckwerke 1 bis 4. In dem ersten Druckwerk sind in herkömmlicher Weise ein Plattenzylinder 5, ein Gummizylinder 6, eine Anlegetrommel 7, die die zu bedruckenden Bogen 8 von einem Bogenanleger 9 übernimmt, sowie ein Gegendruckzylinder 10 vorgesehen.Figures 1 to 3 show the different positions of the sheets to be printed in the machine. A sheet-fed rotary printing machine here comprises four printing units 1 to 4. In the first printing unit, a plate cylinder 5, a rubber cylinder 6, a feed drum 7, which takes over the sheets 8 to be printed from a sheet feeder 9, and a counter-pressure cylinder 10 are provided in a conventional manner.

Das Druckwerk 2 ist über eine Oberführtrommel 11 mit dem Druckwerk 1 verbunden und umfasst einen Gegendruckzylinder 12, einen Gummizylinder 13, einen Plattenzylinder 14 sowie eine Auslegetrommel 15 und Überführtrommeln 16 und 17, über die die bedruckten Bogen 8 dem dritten Druckwerk 3 zugeführt werden. In diesem ist ein Gegendruckzylinder 18, eine Auslegetrommel 19, ein Gummizylinder 20 und ein Plattenzylinder 21 vorgesehen. Über Trommeln 22, 23 wird schliesslich der in dem Druckwerk 3 bedruckte Bogen 8 dem letzten Druckwerk 4 zugeführt und gelangt an dessen Gegendruckzylinder 24, an den ein mit einem Plattenzylinder 26 zusammenwirkender Gummizylinder 25 anstellbar ist. Nachdem die zu bedruckenden Bogen 8 auf einer Seite mit vierfachem Schöndruck versehen wurden, werden sie über einen Ausleger, beispielsweise in Form eines Kettensystems 27, dem Ausleger 28 zugeführt.The printing unit 2 is connected to the printing unit 1 via an upper guide drum 11 and comprises an impression cylinder 12, a rubber cylinder 13, a plate cylinder 14 and a delivery drum 15 and transfer drums 16 and 17, via which the printed sheets 8 are fed to the third printing unit 3. In this, an impression cylinder 18, a delivery drum 19, a rubber cylinder 20 and a plate cylinder 21 are provided. Finally, the sheet 8 printed in the printing unit 3 is fed to the last printing unit 4 via drums 22, 23 and reaches its counter-pressure cylinder 24, against which a rubber cylinder 25 cooperating with a plate cylinder 26 can be set. After the sheets 8 to be printed have been provided with quadruple face printing on one side, they are fed to the delivery arm 28 via a delivery arm, for example in the form of a chain system 27.

Für die zweite Betriebsart ist der Gummizylinder 6 des ersten Druckwerkes 1 mit Greifern versehen, durch die ein jeweils bei einer jeden zweiten Umdrehung der Anlegetrommel 7 bzw. des Gegendruckzylinders 10 zugeführter Bogen 8 von dem Gegendruckzylinder 10 übernommen und dem Gummizylinder 6 zuführbar ist. Dadurch wird durch den als DiLitho-Plattenzylinder wirkenden Plattenzylinder 5 ein Widerdruck auf die Unterseite des Bogens 8 zwischen den Zylindern 5 und 6 übertragen. Danach wird der mit dem Widerdruck versehene Bogen 8 erneut dem Gegendruckzylinder 10 zugeführt, wie Fig. 2 erkennen lässt. Es ist wesentlich, dass der DiLitho-Plattenzylinder 5 im Druckwerk 1 bei der Widerdruck-Betriebsweise jeweils von dem Gummizylinder 6 abgestellt wird, d.h. von diesem abgehoben ist, wenn der Gummizylinder 6 keinen Bogen führt. Dadurch wird eine unerwünschte Übertragung von Farbe bei dieser Betriebsart von dem DiLitho-Plattenzylinder 5 auf den Gummizylinder 6 vermieden.For the second operating mode, the blanket cylinder 6 of the first printing unit 1 is provided with grippers, by means of which a sheet 8 fed in every second rotation of the feed drum 7 or the impression cylinder 10 is taken over by the impression cylinder 10 and can be fed to the blanket cylinder 6. As a result, the plate cylinder 5, which acts as a DiLitho plate cylinder, transfers a counterpressure to the underside of the sheet 8 between the cylinders 5 and 6. Thereafter, the sheet 8 provided with the counterpressure is again fed to the impression cylinder 10, as can be seen in FIG. 2. It is essential that the DiLitho plate cylinder 5 in the printing unit 1 is turned off by the blanket cylinder 6 in the printing mode, i.e. is lifted from this when the blanket cylinder 6 does not bend. This prevents undesired transfer of color from the DiLitho plate cylinder 5 to the rubber cylinder 6 in this operating mode.

Des weiteren ist es wesentlich, dass alle nachfolgenden Gummizylinder 13, 20, 25 von den zugeordneten Gegendruckzylindern 12, 18, 24 jeweils abgehoben sind, wenn die Gegendruckzylinder keine Bogen führen, was, wie bereits dargelegt, bei jeder zweiten Umdrehung der Fall ist. Dadurch wird auch hier vermieden, dass eine unerwünschte Farbübertragung von den genannten Gummizylindern auf die genannten Gegendruckzylinder erfolgt, da in dem hier beschriebenen Ausführungsbeispiel die Druckwerke 2 bis 4 in der Schöndruck-Betriebsweise arbeiten, wobei die Gummizylinder dieser Druckwerke bekanntlich eingefärbt werden.Furthermore, it is essential that all subsequent rubber cylinders 13, 20, 25 are each lifted off the associated counter-pressure cylinders 12, 18, 24 if the counter-pressure cylinders do not have any arcs, which, as already stated, is the case with every second rotation. This also prevents an undesired ink transfer from the above-mentioned blanket cylinders to the above-mentioned impression cylinders, since in the exemplary embodiment described here the printing units 2 to 4 operate in the straight printing mode, the blankets of these printing units being known to be colored.

Mit der erfindungsgemässen Bogenrotationsdruckmaschine kann somit ohne die Verwendung von zusätzlichen Wendevorrichtungen wahlweise im Schöndruck oder im kombinierten Schön-und Widerdruck gearbeitet werden.With the sheet-fed rotary printing press according to the invention, it is thus possible to work either in straight printing or in combined perfecting without the use of additional turning devices.
