Description

Die Erfindung betrifft eine Bogen-Offsetrotationsdruckmaschine 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 Widerdruckes vorbeigeführt wird.The invention relates to a sheet-fed offset rotary printing machine in series construction with at least two printing units, in each of which the sheet to be printed is guided by a counter-pressure cylinder past a rubber cylinder interacting with a plate cylinder to apply an impression.

Eine Maschine dieser Art 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, in dem zwischen zwei benachbarten Druckwerken Wendetrommeln eingesetzt werden, was zwangsläufig zu hohem Herstellungsaufwand und entsprechendem Platzbedarf führt.A machine of this type 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 in which reversing drums are used between two adjacent printing units, which inevitably leads to a high production outlay and corresponding space requirement.

Aufgabe der Erfindung ist es, eine Bogen-Offsetrotationsdruckmaschine der eingangs bezeichneten Art ohne zusätzliche Raumbeanspruchung und insbesondere ohne Wendevorrichtungen wahlweise im Bedarfsfall auf Widerdruck umschaltbar auszugestalten.The object of the invention is to design a sheet-fed offset rotary printing machine of the type mentioned at the outset without additional space requirements and in particular without turning devices, optionally switchable to back pressure if necessary.

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 zeigen

  • Fig. 1 bis 3 die erfindungsgemäße Bogen-Offsetrotationsdruckmaschine in Reihenbauweise.
This object is achieved by applying the features of the characterizing part of the patent claim. The The invention is explained in detail below using an exemplary embodiment, reference being made to the accompanying drawings. Show in these
  • Fig. 1 to 3, the sheet-fed offset printing press according to the invention in a series construction.

Die Figuren 1 bis 3 lassen die verschiedenen Positionen der zu bedruckenden Bogen in der Maschine erkennen. Die Bogen-Offsetrotationsdruckmaschine umfaßt in dem hier beschriebenen Ausführungsbeispiel 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. In the exemplary embodiment described here, the sheet-fed offset rotary printing press 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 Impression cylinder 10 provided.

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 Oberführtrommeln 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. Ober 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/,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 blanket cylinder 13, a plate cylinder 14 and a delivery drum 15 and upper guide 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, via drums 22, 23, the sheet 8 printed in the printing unit 3 is fed to the last printing unit 4 and reaches its counter-pressure cylinder 24, against which a rubber cylinder 25 interacting 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 over a delivery arm, for example in the form of a chain system Boom 28 fed.

In erfindungsgemäßer Weise 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.In a manner according to the invention, the rubber 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 rubber 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 switched off in each case by the blanket cylinder 6 in the printing mode, i. H. 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 impression cylinders 12, 18, 24 when the impression cylinders do not have any arcs, which, as already explained, is the case with every second revolution. 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 straight printing mode, the blankets of these printing units being known to be colored.

Mit der erfindungsgemäßen Bogen-Offsetrotationsdruckmaschine kann somit ohne die Verwendung von zusätzlichen Wendevorrichtungen wahlweise im Schöndruck oder im kombinierten Schön- und Widerdruck gearbeitet werden. Bezugszeichen:
