Description

Die Erfindung betrifft eine Bogendruckmaschine in Aggregatbauweise.The invention relates to a sheet-fed printing machine in unit construction.

Im Druckmaschinenbau sind als wesentliche Bauformen Satellitendruckmaschinen, Tandemdruckmaschinen und Reihendruckmaschinen/Aggregatdruckmaschinen bekannt (Walenski; Offsetdruck; Polygraph Verlag Frankfurt/M; 1991; Seite 64 ff.).In printing press construction, the main types are satellite printing presses, tandem printing presses and row printing machines / unit printing machines known (Walenski; Offset printing; Polygraph Verlag Frankfurt / M; 1991; Page 64 ff.).

Bei den Satellitendruckmaschinen sind mehrere Zylindergruppen (Offsetzylinder/Druckformzylinder) einem mehrfachgroßen Druckzylinder, der mit einer Bogenzuführung und einer Bogenabführung zusammenwirkt, zugeordnet.The satellite printing presses have several cylinder groups (offset cylinder / printing form cylinder) a multi-size impression cylinder with a sheet feed and a sheet discharge cooperates, assigned.

Bei der Tandembauweise von Druckmaschinen sind mindestens zwei Maschinen durch Übergabezylinder oder ein Kettensystem verbunden hintereinander angeordnet. Jede Maschine ist dabei in Fünfzylinderbauart - ein Druckzylinder, zwei Offsetzylinder und zwei Druckformzylinder - ausgebildet und die erste Maschine ist mit der Bogenzuführung und die zweite Maschine mit der Bogenabführung verbunden.With the tandem construction of printing machines, at least two machines are through Transfer cylinder or a chain system connected in series. Any machine is in five-cylinder design - one impression cylinder, two offset cylinders and two Printing form cylinder - trained and the first machine is with the sheet feeder and the second machine connected to the sheet discharge.

Bei der Aggregatbauweise sind mindestens zwei Dreizylinderdruckwerke - ein Druckzylinder, ein Offsetzylinder, ein Druckformzylinder - durch mindestens einen Übergabezylinder miteinander verbunden. Dem ersten Druckwerk ist dabei die Bogenzuführung und dem letzten Druckwerk die Bogenabführung zugeordnet.In the unit design, at least two three-cylinder printing units - one printing cylinder, an offset cylinder, a printing form cylinder - by at least one transfer cylinder connected with each other. The first printing unit is the sheet feeder and the last one Assigned the sheet discharge to the printing unit.

Es ist auch ein Aggregat-Druckwerk bekannt (DE 197 14 807 A1), welches aus einem Druckzylinder, einem Übergabezylinder und einem Klischeezylinder mit einem Kammerrakeleinfärbsystem besteht.An aggregate printing unit is also known (DE 197 14 807 A1), which consists of a Printing cylinder, a transfer cylinder and a plate cylinder with a chamber doctor blade inking system consists.

Dem Nachteil der Unflexibilität der Satellitenmaschinen steht als Vorteil der hohe Kompaktheitsgrad gegenüber.
Nachteilig bei den Aggregatmaschinen ist die große Bauraum beanspruchende Bauweise, der allerdings eine hohe Variabilität und eine günstige Fertigungsmöglichkeit gegenübersteht.
Bei den Tandemmaschinen, deren Bauweise fast gänzlich vom Markt verschwunden ist, sind eine Vielzahl von Bogenübergaben erforderlich und diese Bauweise ist nicht variabel.
The disadvantage of the inflexibility of the satellite machines is offset by the high degree of compactness.
A disadvantage of the unit machines is the large construction space-consuming construction, which is, however, offset by a high degree of variability and an inexpensive manufacturing option.
The tandem machines, whose design has almost completely disappeared from the market, require a large number of sheet transfers and this design is not variable.

Aus der Druckschrift CH-A 583 096 ist eine Bogendruckmaschine für den Offsetdruck, bestehend aus mindestens zwei Druckwerken, bekannt. CH-A 583 096 is a sheet-fed printing press for offset printing known from at least two printing units.

Die Druckzylinder der Druckwerke haben einen dreifachgroßen Durchmesser, wobei jedem Druckzylinder zwei einfachgroße Offsetzylinder und jedem Offsetzylinder ein einfachgroßer Druckformzylinder zugeordnet ist.
Der Bogentransport von Druckwerk zu Druckwerk erfolgt über einen Übergabezylinder. Dieser weist wie die Druckzylinder einen dreifachgroßen Durchmesser auf.
Nachteilig an dieser Bauart ist, dass der dreifachgroße Übergabezylinder die Druckmaschine lang macht, so dass für deren Aufstellung wiederum ein großer Bauraum benötigt wird.
The printing cylinders of the printing units have a triple-sized diameter, with each printing cylinder being assigned two single-size offset cylinders and each offset cylinder being assigned a single-size printing form cylinder.
The sheet is transported from printing unit to printing unit via a transfer cylinder. Like the printing cylinders, this has a triple size diameter.
A disadvantage of this type of construction is that the triple-sized transfer cylinder makes the printing press long, so that a large installation space is again required for its installation.
