Description

Die Erfindung betrifft eine Bogenrotationsdruckmaschine für den wahlweisen Schöndruck oder Schön- und Widerdruck, in denen der Bogen im Schön- und Widerdruck nach dem Prinzip der Bogenhinterkantenwendung gewendet wird.The invention relates to a sheet-fed rotary printing machine for optional straight printing or perfecting, in which the sheet is based on the principle the trailing edge of the sheet is turned.

In Maschinen dieser Gattung, in denen der Bogen von Druckwerk zu Druckwerk mittels Trommeln gefördert wird, erfolgt die Bogenwendung mittels der Ein- oder der Drei-Trommel-Wendung.In machines of this type, in which the sheet from printing unit to printing unit by means of Drums are promoted, the bow is turned using the single or three-drum turn.

Eine Druckmaschine, in der der Bogen mit der sogenannten Drei-Trommel-Wendung (drei Übergabetrommeln zwischen den Druckwerken) gewendet werden kann, ist durch die Druckschrift DE 23 54 418 bekannt. Zwischen den beiden Druckwerken dieser Druckmaschine, zwischen denen die Bogenwendung stattfindet, ist in Bogenlaufrichtung gesehen, eine erste Übergabetrommel mit einfach-großem Durchmesser, eine zweite Übergabetrommel - die sogenannte Speichertrommel - mit doppelt-großem Durchmesser und eine dritte Übergabetrommel - die sogenannte Wendetrommel - mit einfach-großem Durchmesser angeordnet. Die eigentliche Wendeeinrichtung besteht aus der Speicher- und der Wendetrommel, wobei die Wendetrommel mit dem Wendegreifer ausgestattet ist.A printing press in which the sheet with the so-called three-drum turn (three Transfer drums between the printing units) can be turned is by the document DE 23 54 418 known. Between the two printing units of this printing machine, between which the turning takes place is seen in the direction of the sheet travel, a first Transfer drum with a simple, large diameter, a second transfer drum - the so-called Storage drum - with double-large diameter and a third transfer drum - The so-called turning drum - arranged with a simple-large diameter. The actual turning device consists of the storage drum and the turning drum, whereby the turning drum is equipped with the turning gripper.

Nachteilig an dieser Druckmaschine ist, dass der Bogen während der Förderung zwischen diesen beiden Druckwerken in beiden Betriebsarten infolge der einfach-großen Übergabe- und Wendetrommel einer starken Krümmung unterliegt, was nachteilig bei der Verarbeitung von Materialien größerer Dicke ist.A disadvantage of this printing machine is that the sheet is conveyed between them during conveying two printing units in both operating modes due to the simple-large transfer and Reversing drum is subject to a strong curvature, which is disadvantageous when processing Materials of greater thickness.

Eine Druckmaschine, in der der Bogen gleichermaßen mit der sogenannten Drei-Trommel-Wendung gewendet wird, zeigt die Druckschrift DE 44 03 884.
Diese Druckmaschine ist mit einer Übergabetrommel zwischen den Druckwerken ausgestattet. Zur Bewerkstelligung des Schön- und Widerdruckes wird eine sogenannte Wendebox zwischen zwei benachbarten Druckwerken eingefügt. Die Wendebox ist nach der Übergabetrommel des jeweiligen Druckwerkes angeordnet und sie besteht aus der Speicher- und der Wendetrommel, die beide wie alle bogenführenden Zylinder (Druckzylinder, Übergabetrommeln) einen doppelt-großen Durchmesser aufweisen. Document DE 44 03 884 shows a printing press in which the sheet is equally turned using the so-called three-drum turn.
This printing machine is equipped with a transfer drum between the printing units. A so-called reversing box is inserted between two adjacent printing units to accomplish the perfecting. The turning box is arranged after the transfer drum of the respective printing unit and it consists of the storage and the turning drum, both of which, like all sheet-guiding cylinders (printing cylinders, transfer drums), have a double-large diameter.

Nachteilig an dieser Wendebox ist, dass die Wendetrommel mit zwei Wendegreifersystemen ausgerüstet ist. Die doppelt-großen Zylinder der Drei-Trommel-Wendung gewährleisten zwar einen schlanken Bogenlauf, die Wendetrommel ist jedoch nur mit einem hohen Kostenaufwand herzustellen, da sie zwei Wendegreifer beinhaltet.The disadvantage of this turning box is that the turning drum with two turning gripper systems is equipped. The double-sized cylinders of the three-drum turn ensure a slender sheet run, but the turning drum is only expensive because it contains two reversible grippers.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, eine Bogenrotationsdruckmaschine für den wahlweisen Schöndruck oder Schön- und Widerdruck zu schaffen, die kostengünstig hergestellt werden kann und in der Betriebsart Schön- und Widerdruck einen schlanken Bogenlauf gewährleistet.Starting from this prior art, it is an object of the invention to provide a sheet-fed rotary printing press for optional face printing or face and back printing to create the can be produced inexpensively and one in the perfecting mode ensures slender sheet travel.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des 1. Anspruchs gelöst.According to the invention, this object is achieved by the features of claim 1.

Die erfindungsgemäße Bogenrotationsdruckmaschine geht hinsichtlich der Wendeeinrichtung (Speichertrommel, Wendetrommel) von der Erkenntnis aus, dass bei einer einfach-großen Wendetrommel 9 mit nur einem Wendegreifer die Wendetrommel 7 mit geringem Aufwand hergestellt werden kann. Die einfach-große Wendetrommel 7 ist gegenüber einer doppelt-oder mehrfach-großen Wendetrommel mit den entsprechenden Wendegreifern eine kostengünstige Variante.The sheet-fed rotary printing press according to the invention goes with regard to the turning device (Storage drum, turning drum) based on the knowledge that a simple-large Turning drum 9 with only one turning gripper, the turning drum 7 with little effort can be manufactured. The single-sized turning drum 7 is double or multi-sized turning drum with the appropriate turning grippers an inexpensive Variant.

In der Betriebsart Schön- und Widerdruck, wo der Bogen vom Wendegreifer an der Hinterkante ergriffen wird, ist der einfach-große Durchmesser mit einem großen Krümmungsradius für die Bogenförderung nicht hinderlich, da der Bogen in der Wendephase nicht vollflächig auf der Wendetrommel liegt.In the perfecting mode, where the sheet from the reversing gripper at the rear edge is gripped is the simple-large diameter with a large radius of curvature not a hindrance to the sheet conveyance, since the sheet does not cover the entire area during the turning phase lies on the turning drum.

Als Vorteil in beiden Betriebsarten hat sich der zweifach- bzw. dreifach-große Durchmesser des ersten Übergabelzylinders erwiesen, da der große Krümmungsradius den Transport von Materialien größerer Dicke - ohne dass diese beschädigt werden - gewährleistet. The advantage of both operating modes is the double or triple diameter of the first transfer cylinder, since the large radius of curvature means that Materials of greater thickness - without being damaged - guaranteed.

Die Erfindung ist somit in der Kombination folgender technischer Zusammenhänge zu sehen:

  • einfach-große Wendetrommel mit nur einem Wendegreifer (kostengünstige Variante)
  • doppelt- bzw. mehrfach-großer Übergabezylinder als erster Zylinder in der Drei-Trommel-Wendung
  • Wendeeinrichtung, bestehend aus Speicher- und Wendetrommel, deren Einsatz als Einschubaggregat wahlweise zwischen nach dem ersten Übergabezylinder und vor dem Druckzylinder eines vor- und nachgeordneten Druckwerkes möglich ist.
The invention can thus be seen in the combination of the following technical relationships:
  • simple-large turning drum with only one turning gripper (economical variant)
  • double or multiple transfer cylinder as the first cylinder in the three-drum turn
  • Turning device, consisting of storage and turning drum, the use of which as a slide-in unit is optionally possible between after the first transfer cylinder and before the printing cylinder of an upstream and downstream printing unit.

Des Weiteren hat sich als Vorteil erwiesen, dass die in Schöndruckmaschinen vorhandene Phasenlage in den Druckwerken mit eventuell vorhandener Phasengleichheit in allen bzw. einigen Druckwerken nach Einschub der Wendeeinrichtung im Schöndruck gewährleistet ist. Durch eine definierte Anordnung der Speichertrommel in der Wendeeinrichtung (Abstand von der Grundfläche) kann gewährleistet werden, dass die Phasenlage der Druckwerke einer Druckmaschine mit Wendeeinrichtung im Schöndruck gleich der Phasenlage der Druckwerke einer Druckmaschine ohne Wendeeinrichtung ist.
Dies hat zum Vorteil, dass bei Phasengleichheit in den bzw. einigen Druckwerken gleiche technische Ereignisse (z.B. Plattenwechsel) in phasengleichen Druckwerken gleichzeitig ablaufen können.It has also proven to be an advantage that the phase position in the printing presses in the printing units with possible phase equality in all or some printing units is guaranteed after the inserting device has been inserted in the face printing. A defined arrangement of the storage drum in the turning device (distance from the base area) can ensure that the phase position of the printing units of a printing press with a turning device in straight printing is equal to the phase position of the printing units of a printing machine without a turning device.
This has the advantage that, if the phases in the or some printing units are the same, the same technical events (eg plate changes) can take place simultaneously in the same phase printing units.

Anhand eines Ausführungsbeispieles soll nachfolgend die Erfindung näher beschrieben werden.The invention will be described in more detail below using an exemplary embodiment.
