Description

Die Erfindung betrifft ein Druckwerk für eine Rollenrotationsdruckmaschine, in dem die in zwei Druckwerksseitenwänden gelagerten Zylinder etwa Y-förmig angeordnet sind und in das eine zu bedruckende Bahn nach einem aufsteigenden Bahnführungsabschnitt seitlich zwischen zwei Druckwerkzylindern einführbar ist.The invention relates to a printing unit for a web-fed rotary printing press, in which the cylinders mounted in two printing unit side walls are arranged approximately in a Y-shape and into which a web to be printed can be inserted laterally between two printing unit cylinders after an ascending web guide section.

Ein Druckwerk der obenbezeichneten Gattung ist aus dem Fachbuch «Techniken, Systeme, Maschinen» von Oskar Frei, Polygraph-Verlag, Seite 7, bekannt. In Abhängigkeit von der jeweiligen Bahnführung wird die Zugänglichkeit entweder zu den oberen Druckwerkzylinderpaaren oder zu dem unteren Druckwerkzylinderpaar beeinträchtigt.A printing unit of the type described above is known from the specialist book “Techniques, Systems, Machines” by Oskar Frei, Polygraph Verlag, page 7. Depending on the respective web guide, the accessibility to either the upper pair of printing cylinders or the lower pair of printing cylinders is impaired.

Aufgabe der Erfindung ist es, ein Druckwerk dieser Art so zu verbessern, dass eine gute Zugänglichkeit zu allen Druckwerken bei jeglicher Bahnführung geboten wird.The object of the invention is to improve a printing unit of this type in such a way that good access to all printing units is provided with any web guide.

Diese Aufgabe wird durch die Anwendung der Merkmale des kennzeichnenden Teils des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen sowie aus der Beschreibung in Verbindung mit der Zeichnung.This object is achieved by applying the features of the characterizing part of patent claim 1. Advantageous further developments result from the subclaims and from the description in conjunction with the drawing.

Aus der DE-A 2 741 596 ist es zwar bereits bekannt, mit Hilfe von höhenverstellbaren Bühnen die Zugänglichkeit zu den oberen Druckwerkzylindern zu verbessern, jedoch sind derartige Hebebühnen kostenaufwendig und ausserdem allgemein hinderlich. Des weiteren zeigt die DE-A 2932087 Verschwenkvorrichtungen, mit deren Hilfe der Bahnverlauf jeweils so festgelegt wird, dass stets die oberen und unteren Druckwerkzylinderpaare zugänglich sind. Dieser Schwenkmechanismus für die Bahnführungselemente ist ebenfalls konstruktiv aufwendig und erfordert zudem für jede Bahnführung eine spezielle Einstellung. Eine ähnliche, aber bereits wesentlich einfachere Konstruktion offenbart schliesslich die EP-A 0047909, jedoch ist auch hier eine Einstellung der Bahnführungswalzen für die einzelnen Wege erforderlich. Hinzu kommt, dass der vorgenannte Stand der Technik sich auf sogenannte «H-Druckwerke» bezieht, bei denen jeweils jede Seitenwand zwei nach unten ragende Füsse und zwei nach oben ragende Arme aufweist.From DE-A 2 741 596 it is already known to improve the accessibility to the upper printing unit cylinders with the aid of height-adjustable platforms, but such lifting platforms are expensive and moreover generally a hindrance. Furthermore, DE-A 2932087 shows pivoting devices with the aid of which the course of the web is defined in such a way that the upper and lower pairs of printing cylinders are always accessible. This swivel mechanism for the web guide elements is also structurally complex and also requires a special setting for each web guide. Finally, EP-A 0047909 discloses a similar, but already much simpler construction, but here, too, an adjustment of the web guide rollers is necessary for the individual paths. In addition, the above-mentioned prior art relates to so-called “H printing units”, in which each side wall has two downwardly projecting feet and two upwardly projecting arms.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispieles im einzelnen beschrieben, wobei Bezug auf die beiliegende Zeichnung genommen wird. Diese zeigt in schematischer Darstellung eine der beiden Seitenwände 1 eines Druckwerkes für eine Rollenrotationsdruckmaschine für Offsetdruck. In diesem Druckwerk sind die Zylinder 4 bis 9 etwa Y-förmig angeordnet, wobei um einen gemeinsamen, zentralen Zylinder 4 Gummizylinder 5, 6, 7 angeordnet sind, denen jeweils ein Plattenzylinder 8, 9, 10 zugeordnet ist. Jedem der Zylinderpaare 5, 8; 6, 9; 7, 10 ist einem der Feucht- und Farbwerke 11, 12; 13, 14; 15, 16 zugeordnet. Zwischen den nach oben ragenden Armen 2 der Druckwerkseitenwände 1 sind die Feucht- und Farbwerke 11, 12 bzw. 13, 14 angeordnet, während zu den unteren Zylindern 7, 10 das Feucht- und Farbwerk 15, 16 gehört, das zwischen den nach unten ragenden Füssen 3 der beiden Druckwerkseitenwände 1 angeordnet ist.The invention is described in detail below using an exemplary embodiment, reference being made to the accompanying drawing. This shows a schematic representation of one of the two side walls 1 of a printing unit for a web-fed rotary printing press for offset printing. In this printing unit, cylinders 4 to 9 are arranged approximately in a Y-shape, with rubber cylinders 5, 6, 7 being arranged around a common, central cylinder 4, each of which is assigned a plate cylinder 8, 9, 10. Each of the pairs of cylinders 5, 8; 6, 9; 7, 10 is one of the dampening and inking units 11, 12; 13, 14; 15, 16 assigned. The dampening and inking units 11, 12 and 13, 14 are arranged between the upstanding arms 2 of the printing unit side walls 1, while the dampening and inking unit 15, 16 belongs to the lower cylinders 7, 10; Feet 3 of the two printing unit side walls 1 is arranged.

Die Darstellung lässt erkennen, dass in neuartiger Weise die etwa in Form eines «Y» angeordneten Zylinder 4 bis 10 zwischen zwei Seitenwänden 1 angeordnet bzw. in diesen gelagert sind, die etwa die Form eines «einbeinigen H» aufweisen. Wie bereits erwähnt, wird das einzige Bein einer jeden Druckwerkseitenwand 1 mit 3 bezeichnet.The illustration shows that the cylinders 4 to 10, which are arranged approximately in the form of a “Y”, are arranged in a new manner between two side walls 1, and are approximately supported in the form of a “one-legged H”. As already mentioned, the only leg of each printing unit side wall 1 is designated 3.

Soll nun eine Papierbahn 17 in der ausgezogen dargestellten Weise nach einem aufsteigenden Bahnführungsabschnitt A seitlich in das Druckwerk, d.h. zunächst um den Satellitenzylinder 4 und dann zwischen den Gummizylindern 5, 6 hindurch, eingeführt werden, so erfolgt in erfindungsgemässer Weise die Bahnführung im aufsteigenden Bereich über Papierleitwalzen 18, 19, die jeweils zwischen den anstelle des fehlenden zweiten Fusses verwendeten Traversen 20 an oder in Nähe der Druckwerkseitenwände 1 vorgesehen sind. Dadurch wird stets zwischen den Traversen bzw. dem aufsteigenden Bahnführungsabschnitt A und den Füssen 3 der Druckwerkseitenwände 1 ein freier Raum geboten, der einer Bedienungsperson ein ungehindertes Arbeiten an den unteren Zylindern 7, 10 und dem zugeordneten Feucht- und Farbwerk 15, 16 ermöglicht. Ein weiterer wesentlicher Vorteil besteht zusätzlich darin, dass auch die Zylinder 5 und 8 gut von unten zugänglich sind. Ebenso bleiben die Zylinder 6 und 9 frei zugänglich. In vorteilhafter Weise kann an bzw. zwischen den Traversen 20 eine Trittfläche 22 vorgesehen sein, die der Bedienungsperson II das Arbeiten an den oberen Zylindern 5, 8 und dem zugeordneten Feucht- und Farbwerk 11, 12 erleichtert.If a paper web 17 is now to be drawn laterally into the printing unit after an ascending web guide section A, i.e. are first introduced around the satellite cylinder 4 and then between the rubber cylinders 5, 6, the web is guided in the ascending area in the manner according to the invention via paper guide rollers 18, 19, each between or in the vicinity of the crossbars 20 used instead of the missing second foot the printing unit side walls 1 are provided. As a result, a free space is always provided between the traverses or the ascending web guide section A and the feet 3 of the printing unit side walls 1, which enables an operator to work freely on the lower cylinders 7, 10 and the associated dampening and inking unit 15, 16. Another significant advantage is that cylinders 5 and 8 are also easily accessible from below. Cylinders 6 and 9 also remain freely accessible. Advantageously, a tread 22 can be provided on or between the cross members 20, which makes it easier for the operator II to work on the upper cylinders 5, 8 and the associated dampening and inking unit 11, 12.

Wird die zu bedruckende Bahn 21 (gestrichelt dargestellt) auf der anderen Seite des Druckwerkes in das Druckwerk eingeführt, so kann diese über Papierleitwalzen 23, 24 zwischen den Füssen 3 der Druckwerkseitenwände 1 nach oben und anschliessend seitlich eingeführt werden. Zwischen den Füssen 3 bzw. an diesen kann eine weitere Trittfläche 25 verwendet werden, die der Bedienungsperson 111 das Arbeiten an den oberen Zylindern 6, und dem zugeordneten Feucht- und Farbwerk 13, 14 erleichtert. Analog zur Bahnführung 17 bleiben auch bei 21 die Zylinder 6 und 9 sowie 5 und 8 von unten frei zugänglich.If the web 21 to be printed (shown in dashed lines) is inserted into the printing unit on the other side of the printing unit, it can be inserted upwards and then laterally via paper guide rollers 23, 24 between the feet 3 of the printing unit side walls 1. A further step surface 25 can be used between the feet 3 or on these, which makes it easier for the operator 111 to work on the upper cylinders 6 and the associated dampening and inking unit 13, 14. Analogous to the web guide 17, the cylinders 6 and 9 and 5 and 8 remain freely accessible from below at 21.

In vorteilhafter Weise bietet somit das dargestellte Druckwerk freien Zugang zu allen Druckwerkzylindern und Feucht- und Farbwerken unabhängig von der jeweiligen Bahnführung, wobei eine Umstellung der Bahnführungselemente für die einzelnen Wege nicht erforderlich ist.Advantageously, the printing unit shown thus offers free access to all printing unit cylinders and dampening and inking units, irrespective of the respective web guide, it not being necessary to change the web guide elements for the individual paths.
