Description

Die Erfindung betrifft ein Verfahren zum Betreiben einer Druckmaschine, insbesondere einer Bogendruckmaschine, nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for operating a printing machine, in particular a sheet-fed printing press, according to the preamble of claim 1.

Bogendruckmaschinen verfügen über mehrere Druckwerke, durch welche ein bogenförmiger Bedruckstoff bewegt wird, wobei in jedem der Druckwerke ein Teildruckbild in einer Druckfarbe auf den Bedruckstoff aufgetragen wird. Neben den Druckwerken kann eine Bogendruckmaschine als separate Module ausgebildete Lackwerke umfassen, in welchem Lack auf den Bedruckstoff aufgetragen wird.Sheet-fed presses have a plurality of printing units, by which a sheet-shaped substrate is moved, wherein in each of the printing units, a partial printing image is applied in a printing ink on the substrate. In addition to the printing units, a sheet-fed printing press can comprise coating units designed as separate modules, in which lacquer is applied to the printing material.

Aus der DE 197 29 985 A1 sowie der DE 20 2005 003 607 U1 sind Druckwerke von Bogendruckmaschinen bekannt, in welche eine als Lackiereinrichtung ausgebildete Zusatzbearbeitungseinrichtung integriert ist, wobei die dort offenbarten Druckwerke entweder in einem dem Bedrucken des Bedruckstoffs mit Druckfarbe dienenden ersten Betriebsmodus oder in einem zweiten Betriebsmodus, in welchem Lack auf den Bedruckstoff aufgetragen wird, betrieben werden können. Im ersten Betriebsmodus ist ein Farbwerk des Druckwerks angewählt und trägt demnach Druckfarbe auf eine auf dem Formzylinder des Druckwerks positionierte Druckform auf. Im zweiten Betriebsmodus hingegen ist das Farbwerk des jeweiligen Druckwerks abgewählt, so dass dasselbe keine Druckfarbe auf die jeweilige Druckform aufträgt.From the DE 197 29 985 A1 as well as the DE 20 2005 003 607 U1 Printing units of sheet-fed printing machines are known, in which a trained as a painting device additional processing device is integrated, where the printing units disclosed therein either in the printing of the substrate with ink serving first operating mode or in a second operating mode, in which paint is applied to the substrate operated can. In the first operating mode, an inking unit of the printing unit is selected and therefore applies printing ink to a printing form positioned on the forme cylinder of the printing unit. In the second operating mode, however, the inking unit of the respective printing unit is deselected, so that it does not apply any printing ink to the respective printing plate.

Gemäß der DE 20 2005 003 607 U1 sowie der DE 197 29 985 A1 wird ein im zweiten Betriebsmodus abgewähltes Farbwerk, weiches vom jeweiligen Formzylinder des Druckwerks abgestellt ist, weiter angetrieben, wodurch es erforderlich ist, zur Vermeidung von Beschädigungen der Walzen des Farbwerks Drucköl in das Farbwerk einzuleiten. Soll nachfolgend das Druckwerk wieder im ersten Betriebsmodus betrieben werden, in weichem Druckfarbe auf den Bedruckstoff aufgetragen wird, so muss das Drucköl aus dem Farbwerk mit Hilfe eines aufwändigen Farbwerkwaschens entfernt werden. Hierdurch ergeben sich relativ lange Rüstzeiten. Durch das Antreiben des Farbwerks im zweiten Betriebszustand wird weiterhin die volle Antriebsleistung benötigt, wodurch einerseits Verlustleistung und andererseits Wärme in das Druckwerk eingetragen wird.According to the DE 20 2005 003 607 U1 as well as the DE 197 29 985 A1 is an unselected in the second mode inking, which is turned off by the respective form cylinder of the printing unit, further driven, whereby it is necessary to initiate to avoid damage to the rollers of the inking pressure oil in the inking unit. Below is the printing unit again in the first operating mode operated, in soft ink is applied to the substrate, so the pressure oil from the inking unit with the aid of a complex inking machine washing must be removed. This results in relatively long set-up times. By driving the inking unit in the second operating state, the full drive power is still required, which on the one hand power loss and on the other hand heat is entered into the printing unit.

Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zugrunde ein neuartiges Verfahren zum Betreiben einer Druckmaschine zu schaffen.On this basis, the present invention is based on the problem to provide a novel method for operating a printing press.

Dieses Problem wird durch ein Verfahren gemäß Anspruch 1 gelöst. Erfindungsgemäß wird im zweiten Betriebsmodus das Farbwerk sowie gegebenenfalls das Feuchtwerk antriebseitig abgekoppelt und stillgesetzt.This problem is solved by a method according to claim 1. According to the invention the inking unit and optionally the dampening unit is decoupled on the drive side and stopped in the second operating mode.

Im Sinne der hier vorliegenden Erfindung wird vorgeschlagen, im zweiten Betriebsmodus zumindest das Farbwerk des Druckwerks antriebsseitig abzukoppeln und stillzusetzen. Hierdurch kann Antriebsleistung eingespart werden. Durch Stillsetzen zumindest des Farbwerks wird demnach einerseits die Verlustleistung und andererseits der Wärmeeintrag in das Druckwerk minimiert. Bei stillgesetztem Farbwerk wird des Weiteren die Gefahr von Beschädigungen der Farbwerkwalzen minimiert, so dass dann kein Drucköl in das Farbwerk eingebracht werden muss. Hierdurch kann dann, wenn nachfolgend das Druckwerk wieder im ersten Betriebsmodus betrieben werden soll, die Rüstzeit am Druckwerk minimiert werden.For the purposes of the present invention, it is proposed to decouple and stop at least the inking unit of the printing unit on the drive side in the second operating mode. As a result, drive power can be saved. By stopping at least the inking unit on the one hand, the power loss and on the other hand, the heat input is minimized in the printing unit. When the inking unit is stopped, the risk of damage to the inking unit rollers is further minimized, so that then no pressure oil has to be introduced into the inking unit. As a result, when the printing unit is to be operated again in the first operating mode, the set-up time at the printing unit can then be minimized.

Nach einer vorteilhaften Weiterbildung der Erfindung werden im ersten Betriebsmodus der Druckzylinder, der Übertragungszylinder, der Formzylinder, das Farbwerk sowie gegebenenfalls das Feuchtwerk von einem Hauptantrieb der Druckmaschine angetrieben, wobei im zweiten Betriebsmodus das Farbwerk sowie gegebenenfalls das Feuchtwerk vom Hauptantrieb abgekoppelt und stillgesetzt wird.According to an advantageous embodiment of the invention, the printing cylinder, the transfer cylinder, the forme cylinder, the inking unit and optionally the dampening unit are driven by a main drive of the printing press in the first mode, the inking unit and optionally the dampening unit is decoupled from the main drive and shut down in the second operating mode.

Nach einer alternativen vorteilhaften Weiterbildung der Erfindung werden im ersten Betriebsmodus der Druckzylinder, der Übertragungszylinder, das Farbwerk sowie gegebenenfalls das Feuchtwerk von einem Hauptantrieb der Druckmaschine und der Formzylinder von einem demselben zugeordneten Einzelantrieb bzw. Direktantrieb angetrieben, wobei im zweiten Betriebsmodus das Farbwerk sowie gegebenenfalls das Feuchtwerk vom Hauptantrieb abgekoppelt und stillgesetzt wird.According to an alternative advantageous embodiment of the invention, the printing cylinder, the transfer cylinder, the inking unit and optionally the dampening unit are driven by a main drive of the printing press and the forme cylinder of a same associated single drive or direct drive in the first mode of operation, in the second operating mode, the inking unit and possibly the Dampening unit is disconnected from the main drive and shut down.

Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung. Ausführungsbeispiele der Erfindung werden, ohne hierauf beschränkt zu sein, an Hand der Zeichnung näher erläutert. Dabei zeigt:

Nachfolgend wird die hier vorliegende Erfindung unter Bezugnahme auf Fig. 1 in größerem Detail beschrieben.Hereinafter, the present invention will be described with reference to FIG Fig. 1 described in more detail.

Fig. 1 zeigt einen Ausschnitt aus einer Druckmaschine im Bereich eines Druckwerks, wobei vom Druckwerk ein Formzylinder 1, ein Übertragungszylinder 2, ein Druckzylinder 3, ein Farbwerk 4 sowie ein Feuchtwerk 5 dargestellt ist. Auf dem Formzylinder 1 des gezeigten Druckwerks ist mindestens eine Druckform, insbesondere eine Druckplatte, angeordnet, weshalb der Formzylinder 1 auch als Plattenzylinder bezeichnet wird. Auf dem Formzylinder 1 rollt der Übertragungszylinder 2 ab, auf welchem ein Gummituch angeordnet ist. Der Übertragungszylinder 2 wird auch als Gummizylinder bezeichnet. Der Übertragungszylinder 2 rollt auf dem Druckzylinder 3 ab, der auch als Gegendruckzylinder bezeichnet wird. In Fig. 1 ist die Abrollzone zwischen dem Formzylinder 1 und dem Gummizylinder 2 mit der Bezugziffer 6 gekennzeichnet, die Abrollzone zwischen dem Übertragungszylinder 2 und dem Druckzylinder 3 ist durch die Bezugsziffer 7 gekennzeichnet. Fig. 1 shows a section of a printing press in the area of a printing unit, wherein the printing unit a form cylinder 1, a transfer cylinder 2, a printing cylinder 3, an inking unit 4 and a dampening unit 5 is shown. On the form cylinder 1 of the printing unit shown at least one printing plate, in particular a printing plate, arranged, which is why the forme cylinder 1 is also referred to as a plate cylinder. On the forme cylinder 1, the transfer cylinder 2 rolls off, on which a blanket is arranged. The transfer cylinder 2 is also referred to as a rubber cylinder. The transfer cylinder 2 rolls on the impression cylinder 3, which is also referred to as impression cylinder. In Fig. 1 the Abrollzone between the forme cylinder 1 and the blanket cylinder 2 is denoted by the reference numeral 6, the Abrollzone between the transfer cylinder 2 and the impression cylinder 3 is indicated by the reference numeral 7.

Vom Farbwerk 4 des Druckwerks sind Farbauftragwalzen 8 dargestellt, die bei angewähltem Farbwerk auf dem Formzylinder 1 abrollen. Vom Feuchtwerk 5 ist eine Feuchtauftragwalze 9 beziffert, die bei angewähltem Farbwerk und damit angewähltem Feuchtwerk ebenfalls auf dem Formzylinder 1 abrollt.From the inking unit 4 of the printing unit inking rollers 8 are shown, which roll on selected form inking unit 1. From dampening unit 5 a dampening roller 9 is numbered, which also rolls on selected form inking unit and thus selected dampening on the forme cylinder 1.

In das gezeigte Druckwerk ist weiterhin eine Zusatzbearbeitungseinrichtung 10 integriert, die im gezeigten Ausführungsbeispiel als Lackiereinrichtung ausgebildet ist. Die Zusatzbearbeitungseinrichtung 10 verfügt über eine Auftragwalze 11 und eine Kammerrakel 12, wobei die Auftragwalze 11 auf dem Übertragungszylinder 2 abrollt. In der Kammerrakel 12 wird Lack bereitgehalten, der über die Auftragwalze 11 auf den Gummizylinder 2 übertragen werden kann. Im gezeigten Ausführungsbeispiel greift die Zusatzbearbeitungseinrichtung 10 anlegerseitig am Übertragungszylinder 2. Es sei darauf hingewiesen, dass die Zusatzbearbeitungseinrichtung 10 auch auslegerseitig am Übertragungszylinder 2 angreifen kann.In the printing unit shown, an additional processing device 10 is further integrated, which is formed in the embodiment shown as a painting device. The additional processing device 10 has an applicator roller 11 and a chamber doctor blade 12, wherein the applicator roller 11 rolls on the transfer cylinder 2. In the chambered doctor blade 12 paint is kept ready, which can be transmitted to the blanket cylinder 2 via the applicator roller 11. In the exemplary embodiment shown, the additional processing device 10 engages on the transfer cylinder 2 on the feeder side. It should be noted that the additional processing device 10 can also engage on the transfer cylinder 2 on the jib side.

Das in Fig. 1 dargestellte Druckwerk kann in zwei unterschiedlichen Betriebsmodi betrieben werden. In einem ersten Betriebsmodus, der dem Bedrucken eines Bedruckstoffs mit Druckfarbe dient, sind Farbwerk 4 sowie Feuchtwerk 5 angewählt, die Zusatzbearbeitungseinrichtung 10 ist hingegen abgewählt. In diesem ersten Betriebszustand rollen dann die Farbauftragwalzen 8 sowie die Feuchtauftragwalze 9 auf dem Formzylinder 1 ab, der Formzylinder 1 rollt auf dem Übertragungszylinder 2 und der Übertragungszylinder 2 auf dem Druckzylinder 3 ab. Die Auftragwalze 11 der Zusatzbearbeitungseinrichtung 10 ist hingegen vom Übertragungszylinder 2 abgestellt und rollt nicht auf demselben ab. In einem zweiten Betriebsmodus, in welchem die Zusatzbearbeitungseinrichtung 10 angewählt ist, sind das Farbwerk 4 sowie das Feuchtwerk 5 abgewählt. In diesem zweiten Betriebsmodus sind dann die Farbauftragwalzen 8 sowie die Feuchtauftragwalze 9 vom Formzylinder 1 abgestellt, ebenso ist der Formzylinder 1 vom Übertragungszylinder 2 abgestellt. Die Auftragwalze 11 der Zusatzbearbeitungseinrichtung 10 ist hingegen an den Übertragungszylinder 2 angestellt und rollt auf demselben ab.This in Fig. 1 shown printing unit can be operated in two different operating modes. In a first operating mode, which is used to print a printing substrate with ink, inking unit 4 and dampening unit 5 are selected, the auxiliary processing device 10 is deselected, however. In this first operating state then roll the inking rollers 8 and the dampening roller 9 on the forme cylinder 1, the form cylinder 1 rolls on the transfer cylinder 2 and the transfer cylinder 2 on the impression cylinder 3 from. The application roller 11 of the additional processing device 10, however, is turned off by the transfer cylinder 2 and does not roll on the same from. In a second operating mode, in which the additional processing device 10 is selected, the inking unit 4 and the dampening unit 5 are deselected. In this second operating mode then the inking rollers 8 and the dampening roller 9 are turned off from the forme cylinder 1, as well as the forme cylinder 1 is turned off by the transfer cylinder 2. The application roller 11 of the additional processing device 10, however, is employed on the transfer cylinder 2 and rolls on the same from.

Im Sinne der hier vorliegenden Erfindung wird nun vorgeschlagen, dass im zweiten Betriebszustand des Druckwerks zumindest das Farbwerk 4 antriebsseitig abgekoppelt und stillgesetzt wird. Vorzugsweise wird im zweiten Betriebszustand das Farbwerk 4 sowie das Feuchtwerk 5 antriebsseitig abgekoppelt und stillgesetzt, wobei dann die Farbauftragwalzen 8 sowie die Feuchtauftragwalze 9 vom Formzylinder 1 abgestellt sind.For the purposes of the present invention, it is now proposed that in the second operating state of the printing unit, at least the inking unit 4 is decoupled on the drive side and shut down. Preferably, the inking unit 4 and the dampening unit 5 is decoupled on the drive side and stopped in the second operating state, in which case the inking rollers 8 and the dampening roller 9 are turned off by the forme cylinder 1.

In einer ersten Variante der hier vorliegenden Erfindung kann vorgesehen sein, dass im ersten Betriebsmodus der Druckzylinder 3, der Übertragungszylinder 2, der Formzylinder 1, das Farbwerk 4 sowie das Feuchtwerk 5 von einem Hauptantrieb der Druckmaschine angetrieben werden. Im zweiten Betriebsmodus wird dann das Farbwerk 4 sowie das Feuchtwerk 5 vom Hauptantrieb abgekoppelt und stillgesetzt. In dem Fall, in dem der Formzylinder 1 vom Hauptantrieb der Druckmaschine angetrieben wird, kann weiterhin vorgesehen werden, im zweiten Betriebszustand auch den Formzylinder 1 vom Hauptantrieb abzukoppeln und stillzusetzen. In diesem Fall ist dann dem Formzylinder 1 ein Hilfsantrieb zugeordnet. Bei vom Hauptantrieb abgekoppeltem Formzylinder 1 sowie bei vom Formzylinder 1 abgestelltem Farbwerk sowie Feuchtwerk kann dann mit Hilfe des Hilfsantriebs ein Druckplattenwechsel am Formzylinder 1 durchgeführt werden, und zwar parallel zum Betrieb der Zusatzbearbeitungseinrichtung 10.In a first variant of the present invention, it may be provided that in the first operating mode the printing cylinder 3, the transfer cylinder 2, the forme cylinder 1, the inking unit 4 and the dampening unit 5 are driven by a main drive of the printing press. In the second operating mode then the inking unit 4 and the dampening unit 5 is disconnected from the main drive and stopped. In the case in which the forme cylinder 1 is driven by the main drive of the printing press, it can furthermore be provided to decouple and shut down the forme cylinder 1 from the main drive in the second operating state. In this case, then the form cylinder 1 is assigned an auxiliary drive. When decoupled from the main drive cylinder 1 as well as from the form cylinder 1 parked inking unit and dampening can then be carried out with the help of the auxiliary drive a printing plate change on the forme cylinder 1, in parallel to the operation of the auxiliary processing device 10th

Nach einer Alternative der Erfindung wird im ersten Betriebsmodul der Druckzylinder 3, der Übertragungszylinder 2, das Farbwerk 4 sowie das Feuchtwerk 5 vom Hauptantrieb der Druckmaschine angetrieben, der Formzylinder 1 wird hingegen von einem demselben zugeordneten Einzelantrieb bzw. Direktantrieb angetrieben. In diesem Fall wird dann im zweiten Betriebsmodus das Farbwerk 4 sowie das Feuchtwerk 5 vom Hauptantrieb abgekoppelt und stillgesetzt, wobei dann vorzugsweise auch der Formzylinder 1 durch entsprechendes Ansteuern des Einzelantriebs bzw. Direktantriebs stillgesetzt wird.According to an alternative of the invention, the printing cylinder 3, the transfer cylinder 2, the inking unit 4 and the dampening unit 5 is driven by the main drive of the printing press in the first operating module, the form cylinder 1, however, is driven by a same associated single drive or direct drive. In this case, the inking unit 4 and the dampening unit 5 is then disconnected from the main drive and shut down in the second mode of operation, in which case preferably the forme cylinder 1 is stopped by corresponding activation of the individual drive or direct drive.

In beiden Alternativen sind im zweiten Betriebszustand, wie bereits erwähnt, die Farbauftragwalzen 8 des Farbwerks 4 sowie die Feuchtauftragwalze 9 des Feuchtwerks 5 vom Formzylinder 1 abgestellt, ebenso ist der Formzylinder 1 vom Übertragungszylinder 2 abgestellt.In both alternatives, as already mentioned, the inking rollers 8 of the inking unit 4 and the dampening roller 9 of the dampening unit 5 are parked in the second operating state of the form cylinder 1, as well as the forme cylinder 1 is turned off by the transfer cylinder 2.

Im Sinne der hier vorliegenden Erfindung erfolgt das Abkoppeln und Stillsetzen des Farbwerks 4 sowie Feuchtwerks 5 beim Übergang vom ersten Betriebsmodus in den zweiten Betriebsmodus automatisch, nämlich gesteuert bzw. geregelt durch eine Maschinensteuerung der Druckmaschine. Ebenso erfolgt das Abstellen der Farbauftragwalzen 8 des Farbwerks 4 sowie der Feuchtauftragwalze 9 des Feuchtwerks 5 automatisiert durch die Maschinensteuerung. Auch das Abstellen des Formzylinders 1 vom Übertragungszylinder 2 beim Übergang vom ersten Betriebsmodus in den zweiten Betriebsmodus erfolgt automatisiert durch die Maschinensteuerung.For the purposes of the present invention, the decoupling and stopping of the inking unit 4 and dampening unit 5 takes place automatically during the transition from the first operating mode to the second operating mode, namely controlled or regulated by a machine control of the printing machine. Likewise, the parking of the inking rollers 8 of the inking unit 4 and the dampening roller 9 of the dampening unit 5 is automated by the machine control. The parking of the forme cylinder 1 from the transfer cylinder 2 during the transition from the first operating mode to the second operating mode is also automated by the machine control.

Auch in umgekehrter Richtung, also beim Übergang vom zweiten Betriebsmodus in den ersten Betriebsmodus, erfolgt das Anstellen der Farbauftragwalzen 8 des Farbwerks 4 sowie der Feuchtauftragwalze 9 des Feuchtwerks 5 an den Formzylinder 1 automatisiert, ebenso wie das Anstellen des Formzylinders 1 an den Übertragungszylinder 2. Ebenso wird beim Übergang vom zweiten Betriebsmodus auf den ersten Betriebsmodus die Zusatzbearbeitungseinrichtung 10, im gezeigten Ausführungsbeispiel die Auftragwalze 11, automatisiert durch die Maschinensteuerung vom Übertragungszylinder 2 abgestellt.Also in the opposite direction, ie the transition from the second mode to the first operating mode, the hiring of the inking rollers 8 of the inking unit 4 and the dampening roller 9 of the dampening unit 5 is automated to the forme cylinder 1, as well as the hiring of the forme cylinder 1 to the transfer cylinder. 2 Likewise, during the transition from the second operating mode to the first operating mode, the additional processing device 10, in the exemplary embodiment shown, the application roller 11, is automatically turned off by the machine control by the transfer cylinder 2.

Im zweiten Betriebszustand wird die Zusatzbearbeitungseinrichtung 10 vorzugsweise vom Hauptantrieb der Druckmaschine aus angetrieben, wobei hierzu dann im zweiten Betriebszustand die Zusatzbearbeitungseinrichtung 10 automatisiert antriebsseitig an den Hauptantrieb angekoppelt wird. Bei Übergang vom zweiten Betriebsmodus in den ersten Betriebsmodus hingegen wird die Zusatzbearbeitungseinrichtung 10 vom Hauptantrieb abgekoppelt und stillgesetzt.In the second operating state, the additional processing device 10 is preferably driven by the main drive of the printing machine, in which case the additional processing device 10 is then automatically coupled on the drive side to the main drive in the second operating state. In the transition from the second operating mode in the first operating mode, however, the additional processing device 10 is decoupled from the main drive and stopped.

In der bevorzugten Ausführungsform ist die Zusatzbearbeitungseinrichtung 10 als Lackiereinrichtung ausgebildet, deren Auftragwalze 11 mit dem Übertragungszylinder 2 zusammenwirkt. Es sei darauf hingewiesen, dass auch eine Ausführungsform vorstellbar ist, in welcher die Zusatzbearbeitungseinrichtung als mit dem. Formzylinder 1 zusammenwirkende Lackiereinrichtung ausgebildet ist. Die Lackiereinrichtung kann im Unterscheid zum gezeigten Kammerrakelsystem auch als Rasterwalzensystem ausgeführt sein.In the preferred embodiment, the additional processing device 10 is formed as a painting, the applicator roller 11 cooperates with the transfer cylinder 2. It should be noted that an embodiment is conceivable in which the additional processing device than with the. Form cylinder 1 cooperating painting device is formed. In contrast to the illustrated chamber doctor blade system, the painting device can also be designed as an angled roller system.

Ebenso kann die Zusatzbearbeitungseinrichtung als Stanzeinrichtung oder Prägeeinrichtung oder Längsschneideeinrichtung ausgeführt sein. Weiterhin ist vorstellbar, dass es sich bei der in das Druckwerk integrierten Zusatzbearbeitungseinrichtung um eine Inkjet-Einrichtung handelt, die entweder direkt oder indirekt über den Gummizylinder einem individualisierenden Bedrucken der Bedruckstoffe bzw. Druckbogen dient.Likewise, the additional processing device can be designed as a punching device or embossing device or longitudinal cutting device. It is also conceivable that the additional processing device integrated in the printing unit is an inkjet device which serves either directly or indirectly via the blanket cylinder for individualizing printing of the printing materials or printed sheets.

Wie bereits erwähnt, kann dann, wenn das Druckwerk im zweiten Betriebsmodus bei angewählter Zusatzbearbeitungseinrichtung 10 betrieben wird, am Formzylinder 1 automatisiert ein Plattenwechsel durchgeführt werden, und zwar dann, wenn dem Formzylinder 1 entweder ein Eigenantrieb bzw. Direktantrieb oder ein Hilfsantrieb zugeordnet ist. Ebenso kann im zweiten Betriebsmodus bei angewählter Zusatzbearbeitungseinrichtung 10 das Farbwerk automatisiert gewaschen werden.As already mentioned, when the printing unit is operated in the second operating mode when the auxiliary processing device 10 is selected, a plate change can be carried out automatically on the forme cylinder 1, specifically if the forme cylinder 1 is assigned either a self-propelled or direct drive or an auxiliary drive. Likewise, in the second operating mode with selected auxiliary processing device 10, the inking unit can be automatically washed.

Abschließend sei darauf hingewiesen, dass eine Druckmaschine mehrere Druckwerke mit in die Druckwerke integrierten Zusatzbearbeitungseinrichtungen aufweisen kann, wobei jedes dieser Druckwerke im Sinne der hier vorliegenden Erfindung betrieben werden kann. Dabei kann in ein Druckwerk einer Druckmaschine z. B. eine Lackiereinrichtung und in ein anderes Druckwerk z. B. eine Perforationseinrichtung bzw. Stanzeinrichtung oder eine Inkjet-Einrichtung integriert sein. Diesbezüglich sind beliebige Kombinationen vorstellbar.Finally, it should be noted that a printing press can have a plurality of printing units with additional processing devices integrated in the printing units, wherein each of these printing units can be operated in the sense of the present invention. It can in a printing unit of a printing machine z. B. a painting and z. B. a perforation or punching device or an inkjet device be integrated. In this regard, any combinations are conceivable.
