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 the optional Perfecting or perfecting, in which the bow is in perfecting after the principle the bow trailing edge turn 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 is promoted, the sheet is turned using the one or three-drum twist.
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 twist (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 bowing takes place is seen in sheet travel direction, a first transfer drum with a single-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 single-large diameter. The actual turning device consists of the storage and the turning drum, wherein 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.The disadvantage of this printing machine is that the bow during the promotion between these two printing units in both operating modes as a result of the simply large transfer and beater is subject to a strong curvature, which is disadvantageous in processing of 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. A printing press, in which the sheet is turned equally with the so-called three-drum turn, shows the document DE 44 03 884.
This press is equipped with a transfer drum between the printing units. To accomplish the perfecting a so-called Wendebox between two adjacent printing units is inserted. 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 cylinder, 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.A disadvantage of this Wendebox is that the turning drum with two Wendebreifersystemen equipped. Although the double-sized cylinder of the three-drum turn guarantee a sleek bow, the beater is only with a high cost because it contains two turning grippers.
Aus der Druckschrift EP 0 381 012 A ist in einer Druckmaschine in Reihenbauweise eine
Bogenwendevorrichtung bekannt. Die Druckmaschine besteht aus gegenüber Form- und
Gummizylinder doppelt-großen Druckzylindern, die durch mindestens eine Übergabetrommel
verbunden sind.
Druckzylinder und Übergabetrommel sind dabei in Reihe angeordnet.
Zum Zweck der Bogenwendung sind außerhalb der Reihenanordnung eine Speichertrommel
mit doppelt-großem Durchmesser sowie eine Wendetrommel mit einfach-großem Durchmesser
vorgesehen. Die Speichertrommel ist der Übergabetrommel zugeordnet. Zwischen der
Speichertrommel und dem zweiten Druckzylinder ist die Wendetrommel angeordnet. Speichertrommel
und Wendetrommel liegen unterhalb von Übergabetrommel bzw. Druckzylinder.
Die Speichertrommel und die Wendetrommel dienen nur in der Betriebsart Schön- und Widerdruck
der Bogenführung. In der Betriebsart Schöndruck sind sie unwirksam.
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.From the document EP 0 381 012 A a sheet turning device is known in a printing machine in a row construction. The printing press consists of double-sized printing cylinders, which are connected by at least one transfer drum.
Printing cylinder and transfer drum are arranged in series.
For the purpose of the perfecting a storage drum with double-large diameter and a single-diameter turning drum are provided outside the row arrangement. The storage drum is assigned to the transfer drum. Between the storage drum and the second printing cylinder, the turning drum is arranged. Storage drum and beater are below transfer drum or impression cylinder.
The storage drum and the beater are used only in the mode perfecting bowing. In the mode of recto printing they are ineffective.
Based on this prior art, it is an object of the invention to provide a sheet-fed rotary printing machine for the optional Perfecting or perfecting, which can be produced inexpensively and ensures a sleek sheet travel in the perfecting mode.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des 1. Anspruchs gelöst.According to the invention, this object is achieved by the features of the first claim.
Die erfindungsgemäße Bogenrotationsdruckmaschine geht hinsichtlich der Wendeeinrichtung (Speichertrommel, Wendetrommel) von der Erkenntnis aus, dass bei einer einfach-großen Wendetrommel mit nur einem Wendegreifer die Wendetrommel mit geringem Aufwand hergestellt werden kann. Die einfach-große Wendetrommel ist gegenüber einer doppelt- oder mehrfach-großen Wendetrommel mit den entsprechenden Wendegreifern eine kostengünstige Variante. 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.The sheet-fed rotary printing press according to the invention is concerned with respect to the turning device (Storage drum, beater) from the realization that at a single-large Turning drum with only one turning gripper the turning drum with low Effort can be made. The single-large beater is opposite one double or multi-size turning drum with the corresponding turning grippers one cost-effective variant. In perfecting mode, where the arc from the turning gripper at the trailing edge is the single-large diameter with a large radius of curvature not a hindrance to the sheet promotion, since the arc in the turning phase is not complete is on the turning drum.
Als Vorteil in beiden Betriebsarten hat sich der zweifach- bzw. dreifach-große Durchmesser des ersten Übergabezylinders erwiesen, da der große Krümmungsradius den Transport von Materialien größerer Dicke - ohne dass diese beschädigt werden - gewährleistet.As an advantage in both modes has the double or triple-large diameter the first transfer cylinder proved because the large radius of curvature transport of Materials of greater thickness - without these being damaged - guaranteed.
Eine spezielle Ausführungsform der 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.
- single-large turning drum with only one turning gripper (cost-effective variant)
- double or multi-size transfer cylinder as the first cylinder in the three-drum turn
- Turning device, consisting of storage and turning drum, the use of which is possible as a plug-in unit either between after the first transfer cylinder and before the printing cylinder of a 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.Furthermore, it has proven to be advantageous that the existing in straight printing machines phase position is guaranteed in the printing units with any existing phase in all or some printing units after inserting the turning device in recto printing. By a defined arrangement of the storage drum in the turning device (distance from the base) can be ensured that the phase position of the printing units of a printing press with turning device in Perfecting equal to the phase position of the printing units of a printing press without turning device.
This has the advantage that the same technical events (eg plate change) in phase-identical printing units can take place at the same time in the same or in some printing units.
Anhand eines Ausführungsbeispieles soll nachfolgend die Erfindung näher beschrieben werden.Reference to an embodiment, the invention will be described in more detail below.
