Eine Bogendruckmaschine verfügt über mehrere Druckwerke zum Bedrucken eines bogenförmigen Bedruckstoffs mit Druckfarbe. Aus der Praxis bekannte Druckwerke einer Bogendruckmaschine verfügen über einen Formzylinder, einen Übertragungszylinder, einen Druckzylinder, ein Farbwerk sowie gegebenenfalls ein Feuchtwerk. Auf dem Formzylinder eines Druckwerks ist mindestens eine Druckform, zum Beispiel eine Druckplatte, angeordnet, wobei mithilfe des Farbwerks Druckfarbe und mithilfe des gegebenenfalls vorhandenen Feuchtwerks Feuchtmittel auf die oder jede auf dem Formzylinder positionierte Druckform aufgetragen werden kann. Der Formzylinder rollt dem Übertragungszylinder ab, auf welchem mindestens eine Übertragungsform positioniert ist. Der Übertragungszylinder rollt unter Ausbildung eines Druckspalts für einen zu bedruckenden, bogenförmigen Bedruckstoff auf dem Druckzylinder ab, welcher den zu bedruckenden Bedruckstoff führt. Der Formzylinder eines Druckwerks wird auch als Plattenzylinder und der Übertragungszylinder auch als Gummizylinder bezeichnet.A sheetfed press has several printing units for printing on a sheet-shaped substrate with printing ink. From the practice known printing units of a sheet-fed press have a form cylinder, a transfer cylinder, a printing cylinder, an inking unit and optionally a dampening unit. At least one printing forme, for example a printing plate, is arranged on the forme cylinder of a printing unit, wherein dampening means can be applied to the or each printing form positioned on the forme cylinder with the aid of the inking unit. The forme cylinder rolls off the transfer cylinder, on which at least one transfer mold is positioned. The transfer cylinder rolls off to form a printing nip for a sheet-shaped printing material to be printed on the printing cylinder, which leads to the printing material to be printed. The form cylinder of a printing unit is also referred to as a plate cylinder and the transfer cylinder as a rubber cylinder.
Bei Bogendruckmaschinen, die über mindestens einen Hauptantrieb jedoch über keine Direktantriebe zum eigenmotorischen Antreiben von Zylindern der Druckwerke verfügen, werden im Druckbetrieb sämtliche Zylinder eines Druckwerks, also der Formzylinder, der Übertragungszylinder und der Druckzylinder, sowie sämtliche Walzen des Farbwerks des Druckwerks von dem Hauptantrieb aus angetrieben. Die vorliegende Erfindung betrifft ein Druckwerk, bei welchem im Druckbetrieb alle Zylinder des Druckwerks sowie Walzen des Farbwerks vom Hauptantrieb aus angetrieben werden.In sheetfed presses, which have at least one main drive but no direct drives for self-propelled cylinders of the printing units, all cylinders of a printing unit, so the form cylinder, the transfer cylinder and the printing cylinder, as well as all the rollers of the inking unit of the printing unit from the main drive in printing operation driven. The present invention relates to a printing unit in which all cylinders of the printing unit and rollers of the inking unit are driven by the main drive during printing operation.
Bei einem solchen Druckwerk bereitet die Minimierung von zur Durchführung von Rüstarbeiten benötigten Rüstzeiten Schwierigkeiten. Zur Effektivitätssteigerung von Bogendruckmaschinen ist es jedoch erforderlich, die zur Ausführung von Rüstarbeiten benötigten Rüstzeiten zu verkürzen. Es besteht daher Bedarf an einem neuartigen Druckwerk, mithilfe dessen Rüstzeiten verkürzt werden können, um die Effektivität einer Bogendruckmaschine zu steigern.In such a printing unit, the minimization of set-up time required to carry out set-up work presents difficulties. To increase the effectiveness of sheet-fed presses, however, it is necessary to shorten the set-up time required to carry out set-up work. There is therefore a need for a novel printing unit, with the help of which set-up times can be shortened in order to increase the effectiveness of a sheet-fed press.
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde ein neuartiges Druckwerk zu schaffen, mit Hilfe dessen Rüstzeiten minimiert werden können. Diese Aufgabe wird durch ein Druckwerk gemäß Anspruch 1 gelöst. Das erfindungsgemäße Druckwerk umfasst zumindest folgende Merkmale: der Formzylinder ist über eine erste schaltbare Kupplung antriebsseitig vom Hauptantrieb abkoppelbar und an denselben ankoppelbar, nämlich derart, dass bei geschlossener erster Kupplung der Formzylinder über die schaltbare erste Kupplung an den Hauptantrieb angekoppelt ist, und dass bei geöffneter erster Kupplung der Formzylinder vom Hauptantrieb abgekoppelt und an einen Formzylinderhilfsantrieb ankoppelbar ist; das Farbwerk ist über eine zweite schaltbare Kupplung antriebsseitig vom Hauptantrieb abkoppelbar und an denselben ankoppelbar, nämlich derart, dass bei geschlossener zweiter Kupplung das Farbwerk über die schaltbare zweite Kupplung an den Hauptantrieb angekoppelt ist, und dass bei geöffneter zweiter Kupplung das Farbwerk vom Hauptantrieb abgekoppelt ist.On this basis, the present invention seeks to provide a novel printing unit, with the help of the set-up times can be minimized. This object is achieved by a printing unit according to
Das erfindungsgemäße Druckwerk einer Bogendruckmaschine verfügt über einen vom Hauptantrieb der Druckmaschine auskuppelbaren Formzylinder sowie ein ebenfalls vom Hauptantrieb auskuppelbares Farbwerk. Im Druckbetrieb sind sämtliche Zylinder des Druckwerks, also der Druckzylinder, der Übertragungszylinder und der Formzylinder, sowie die Walzen des Farbwerks an den Hauptantrieb angekoppelt und werden von demselben aus angetrieben. Zur Ausführung von Rüstarbeiten kann einerseits der Formzylinder vom Hauptantrieb abgekoppelt werden, weiterhin können die Walzen des Farbwerks vom Hauptantrieb abgekoppelt werden, nämlich jeweils über eine schaltbare Kupplung.The printing unit of a sheet-fed printing press according to the invention has a forme cylinder which can be disengaged from the main drive of the printing press and also an inking unit which can likewise be disengaged from the main drive. In printing operation, all cylinders of the printing unit, so the printing cylinder, the transfer cylinder and the forme cylinder, and the rollers of the inking unit are coupled to the main drive and are driven by the same. To carry out set-up work, on the one hand, the forme cylinder can be decoupled from the main drive, furthermore, the rollers of the inking unit can be decoupled from the main drive, namely via a switchable coupling.
So dient die erste schaltbare Kupplung dem Abkoppeln oder Ankoppeln des Formzylinders an den Hauptantrieb, die zweite schaltbare Kupplung dient dem Ankoppeln oder Abkoppeln des Farbwerks an den Hauptantrieb. Bei einem solchen Druckwerk können Rüstzeiten durch Parallelisierung von Rüstvorgängen bzw. Rüstarbeiten verkürzt werden. So ist es beim erfindungsgemäßen Druckwerk insbesondere möglich, einen Druckplattenwechsel im Formzylinder des Druckwerks sowie ein Farbwerkwaschen des Farbwerks und/oder ein Wachen der auf dem Übertragungszylinder positionierten Übertragungsform und/oder ein Waschen des Druckzylinders zu parallelisieren. Hierdurch kann Rüstzeit eingespart werden.Thus, the first switchable coupling is used for uncoupling or coupling the forme cylinder to the main drive, the second switchable coupling is used for coupling or uncoupling of the inking unit to the main drive. In such a printing setup times can be shortened by parallelization of set-up operations or set-up. Thus, in the printing unit according to the invention, it is in particular possible to parallelize a printing plate change in the forme cylinder of the printing unit as well as inking unit washing of the inking unit and / or monitoring of the transfer mold positioned on the transfer cylinder and / or washing of the printing cylinder. As a result, set-up time can be saved.
Ein weiterer Vorteil des erfindungsgemäßen Druckwerks besteht darin, dass durch das selektive und individuelle Stillsetzen des Formzylinders und/oder Farbwerks der Energieverbrauch eines Druckwerks reduziert werden kann. So kann bei Nicht-Benutzung des Formzylinders der Formzylinder still gesetzt werden. Bei Nicht-Benutzung des Farbwerks kann das Farbwerk still gesetzt werden. Hierdurch kann der Energieverbrauch reduziert und ein Verschleiß im Druckwerk minimiert werden.Another advantage of the printing unit according to the invention is that the energy consumption of a printing unit can be reduced by the selective and individual stopping of the forme cylinder and / or inking unit. Thus, when not using the forme cylinder, the forme cylinder can be shut down. When not using the inking unit, the inking unit can be set to stand still. As a result, the energy consumption can be reduced and wear in the printing unit can be minimized.

Die gezeigten, bevorzugten Ausführungsbeispiele der erfindungsgemäßen Druckwerke 1, 1' und 1" verfügen vorzugsweise weiterhin über ein Feuchtwerk, wobei ein Feuchtwerk mindestens eine Walze umfasst, mithilfe derer auf eine auf dem Formzylinder 4 positionierte Druckform Feuchtmittel aufgetragen werden kann.The illustrated, preferred embodiments of the
Vorzugsweise werden im Druckbetrieb sämtliche Walzen des Feuchtwerks vom Hauptantrieb aus angetrieben. Dabei ist das Feuchtwerk vorzugsweise über ein Getriebe an den Hauptantrieb angekoppelt, wobei dem Getriebe eine weitere schaltbare Kupplung zugeordnet sein kann, nämlich derart, dass bei geschlossener schaltbarer Kupplung das Feuchtwerk dieselbe an den Hauptantrieb angekoppelt und bei geöffneter schaltbarer Kupplung das Feuchtwerk vom Hauptantrieb abgekoppelt ist. In diesem Fall kann dann das Feuchtwerk zur Ausführung von Rüstarbeiten still gesetzt werden.Preferably, all rollers of the dampening unit are driven by the main drive in the printing operation. The dampening unit is preferably coupled via a transmission to the main drive, wherein the transmission can be associated with a further switchable coupling, namely such that with closed switchable coupling the dampening unit coupled the same to the main drive and the dampening unit is disconnected from the main drive with open switchable coupling , In this case, the dampening unit can then be shut down to carry out set-up work.
Im Unterschied hierzu ist es auch möglich, die Walzen des Feuchtwerks im Druckbetrieb nicht vom Hauptantrieb aus anzutreiben, sondern von einem dem Feuchtwerk zugeordneten Direktantrieb bzw. Direktantrieb oder Einzelantrieb.In contrast, it is also possible not to drive the rollers of the dampening unit in the printing operation from the main drive, but from a dampening unit associated with the direct drive or direct drive or single drive.
Sämtliche vorhandenen Antriebe, also der Hauptantrieb sowie der oder jeder Hilfsantrieb sowie gegebenenfalls ein Einzelantrieb für die Walzen des Feuchtwerks können hinsichtlich ihres Betriebszustands überwacht werden. Ebenfalls können sämtliche vorhandenen Kupplungen, also die erste schaltbare Kupplung 21 und die zweite schaltbare Kupplung 27 sowie gegebenenfalls die dritte schaltbare Kupplung 30 sowie gegebenenfalls vorhandene weitere Kupplungen hinsichtlich ihres Betriebszustands überwacht werden. Sämtliche Rüstvorgänge, Kupplungsvorgänge und Positioniervorgänge für das Einkuppeln des Farbwerks 5 sowie des Formzylinders 4 laufen weitestgehend parallelisiert ab, wobei das Farbwerk 5 bezüglich eines sogenannten Hebertakts einer Heberwalze des Farbwerks 5 und bezüglich einer seitlichen Verreibung über die Maschinensteuerung synchron und taktgenau eingekuppelt werden kann.All existing drives, so the main drive and the or each auxiliary drive and optionally a single drive for the rolls of dampening can be monitored in terms of their operating condition. Likewise, all existing clutches, ie the first

In diesem Fall ist dann auf dem Übertragungszylinder 3 des jeweiligen Druckwerks eine Lackform angeordnet, auf die über das Lackiersystem Lack aufgetragen werden kann, welches dann vom Übertragungszylinder auf den Bedruckstoff, der durch den Druckspalt 8 zwischen Druckzylinder 2 und Übertragungszylinder 3 transportiert wird, aufgetragen wird.In this case, a paint form is then arranged on the
Zum Antrieb des Lackiersystems kann dasselbe zum Bespiel über eine schaltbare Kupplung an den Hauptantrieb angekoppelt werden. Im Unterschied hierzu ist es jedoch auch möglich, das Lackiersystem des erfindungsgemäßen Druckwerks über einen Einzelantrieb bzw. Direktantrieb des Lackiersystems anzutreiben.To drive the painting system, the same can be coupled for example via a switchable coupling to the main drive. In contrast, however, it is also possible to drive the paint system of the printing unit according to the invention via a single drive or direct drive of the paint system.
Wie bereits ausgeführt, kommt das erfindungsgemäße Druckwerk insbesondere an einer Bogendruckmaschine mit mehreren solchen Druckwerken zum Einsatz. Eine Bogendruckmaschine, die ein erfindungsgemäßes Druckwerk umfasst, kann für den reinen Schöndruckbetrieb oder auch für den Schöndruck und Widerdruckbetrieb ausgelegt sein.As already stated, the printing unit according to the invention is used in particular on a sheet-fed printing press with a plurality of such printing units. A sheet-fed printing press, which comprises a printing unit according to the invention, can be designed for pure straight printing operation or else for straight printing and perfecting operation.
Zusätzlich kann eine Druckmaschine mit einem solchen Druckwerk ein separates Lackwerk umfassen.In addition, a printing press with such a printing unit may comprise a separate coating unit.
