Description

Die Erfindung betrifft eine Druckmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a printing press according to the preamble of claim 1.

Aus dem Stand der Technik, nämlich aus der EP 0 812 683 A1 , ist eine Bogendruckmaschine mit mehreren Druckwerken bekannt, wobei jedes der Druckwerke einen Gegendruckzylinder, einen auf dem Gegendruckzylinder abrollenden Gummizylinder, einen auf dem Gummizylinder abrollenden Formzylinder sowie ein Farbwerk und ein Feuchtwerk umfasst. Bei der dort offenbarten Bogendruckmaschine werden die Gegendruckzylinder, die Gummizylinder, die Farbwerke sowie die Feuchtwerke der Druckwerke von einem Hauptantrieb angetrieben. Den Formzylindern der Druckwerke sind hingegen Eigenantriebe bzw. Direktantriebe zugeordnet, welche die Formzylinder entkoppelt vom Hauptantrieb der Druckmaschine eigenmotorisch antreiben. Unter Fortdruckbedingungen der Druckwerke werden nach diesem Stand der Technik die Gegendruckzylinder, die Gummizylinder, die Farbwerke sowie die Feuchtwerke der Druckwerke vom Hauptantrieb angetrieben, die Formzylinder der Druckwerke werden hingegen von den jeweiligen Direktantrieben angetrieben, und zwar synchronisiert zum Hauptantrieb.From the prior art, namely from the EP 0 812 683 A1 , A sheet-fed press with several printing units is known, wherein each of the printing units comprises a counter-pressure cylinder, a rolling on the impression cylinder rubber cylinder, a rolling on the blanket cylinder cylinder and an inking unit and a dampening unit. In the sheet-fed printing machine disclosed there, the impression cylinders, the blanket cylinders, the inking units and the dampening units of the printing units are driven by a main drive. The cylinders of the printing units, however, are associated with their own drives or direct drives, which drive the form cylinder decoupled from the main drive of the printing press eigenmotorisch. Under production conditions of the printing units, the impression cylinders, the blanket cylinders, the inking units and the dampening units of the printing units are driven by the main drive according to this prior art, the form cylinder of the printing units, however, are driven by the respective direct drives, and synchronized to the main drive.

An einer solchen Druckmaschine, deren Formzylinder im Fortdruckbetrieb mit Hilfe von den Formzylindern zugeordneten Direktantrieben angetrieben werden, können sich Druckqualitätsstörungen ausbilden, die durch Drehmomentschwankungen im entsprechenden Druckwerk verursacht werden. Es besteht daher ein Bedarf an einer Druckmaschine, mit Hilfe dessen durch Drehmomentschwankungen verursachte Druckqualitätsstörungen vermieden werden können.On such a printing machine, the form cylinder are driven in the continuous printing operation by means of the form cylinders associated direct drives, print quality disturbances can form, which are caused by torque fluctuations in the corresponding printing unit. There is therefore a need for a printing press that can be used to avoid print quality disturbances caused by torque fluctuations.

EP-A-0 699 524 offenbart verschiedene Antriebsprinzipien für eine Offsetdruckmaschine mit Druckwerken nach dem Prinzip Gummi-Gummi, wobei ein Druckwerk mit einem Gegendruckzylinder ein Dreizylinderdruckwerk bilden kann. EP-A-0 699 524 discloses various drive principles for an offset printing press with printing units on the rubber-rubber principle, wherein a printing unit with a counter-pressure cylinder can form a three-cylinder printing unit.

EP-A-1759839 offenbart eine Bogendruckmaschine mit mehreren Druckwerken, wobei jedes Druckwerk einen Formzylinder, einen Gummizylinder, einen gegendruckzylinder sowie ein Farb- und Feuchtwerkaufweist, wobei lediglich der formzylinder eigenmotorisch von einen demselben zugeordnenten direktantrieb im Fortdruckbetrieb antreibbar ist, wahrend der gummi-, der gegendruckzylinder sowie der Farb- und feuchtwerk von einem Hauptantrieb der Druckmaschine unter Fortdruckbedingungen antreibbar sind. EP-A-1759839 discloses a sheet-fed printing machine with multiple printing units, each printing unit a form cylinder, a rubber cylinder, a counter-pressure cylinder and a inking and dampening has, wherein only the form cylinder self-propelled by a same zugeordnenten direct drive in the continuous printing operation, while the rubber, the counter-pressure cylinder and the color - And dampening unit can be driven by a main drive of the printing press under production conditions.

Nach einem ersten Aspekt kann jeder Zylinder eines Druckwerks von einem separaten Elektromotor angetrieben werden. Nach einem zweiten Aspekt ist nur ein Zylinder mit einem Elektromotor antriebsseitig verbunden und die weiteren Zylinder sind untereinander mittels Räderzug verbunden.According to a first aspect, each cylinder of a printing unit can be driven by a separate electric motor. According to a second aspect, only one cylinder is connected to the drive side with an electric motor and the other cylinders are connected to one another by means of a gear train.

In einer Weiterbildung kann ein Feuchtreiber eines Feuchtwerks mit einem Elektromotor antriebsseitig gekoppelt sein.In a further development, a dampening drive of a dampening unit can be coupled with an electric motor on the drive side.

Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zugrunde eine neuartige Druckmaschine zu schaffen.On this basis, the present invention is based on the problem to provide a novel printing press.

Dieses Problem wird durch eine Druckmaschine gemäß Anspruch 1 gelöst. Erfindungsgemäß ist dem Feuchtwerk ein separater Direktantrieb zugeordnet, der das Feuchtwerk im Fortdruckbetrieb eigenmotorisch und damit unabhängig vom Hauptantrieb sowie vom Direktantrieb des Formzylinders antreibt.This problem is solved by a printing machine according to claim 1. According to the dampening unit is associated with a separate direct drive, which drives the dampening unit in the production mode self-propelled and thus independent of the main drive and the direct drive of the forme cylinder.

Mit der hier vorliegenden Erfindung wird vorgeschlagen, den Feuchtwerken der Druckwerke jeweils einen separaten Direktantrieb zuzuordnen. Im Fortdruckbetrieb wird dann ein Feuchtwerk von dem demselben zugeordneten Direktantrieb eigenmotorisch angetrieben. In diesem Fall besteht dann keine mechanische Antriebverbindung über Zahnräder zwischen dem Farbwerk und dem Formzylinder sowie Gummizylinder des jeweiligen Druckwerks, sodass eine Rückwirkung des Feuchtwerkantriebs auf die Zylinder des Druckwerks vermieden werden kann. Hierdurch können Drehmomentschwankungen im Druckwerk vermieden werden, sodass Druckqualitätsstörungen durch Drehmomentschwankungen eliminiert werden können.With the present invention, it is proposed to assign each of the dampening units of the printing units a separate direct drive. In the continuous printing operation, a dampening unit is then driven in an eigenmotoric manner by the same direct drive assigned to it. In this case, there is then no mechanical drive connection via gears between the inking unit and the forme cylinder and blanket cylinders of the respective printing unit, so that a reaction of the dampening unit drive can be avoided on the cylinder of the printing unit. This can be used to avoid torque fluctuations in the printing unit, so that print quality disturbances can be eliminated by torque fluctuations.

Nach einer vorteilhaften Weiterbildung der Erfindung ist auch dem Farbwerk der Druckwerke jeweils mindestens ein separater Direktantrieb zugeordnet, der das Farbwerk im Fortdruckbetrieb eigenmotorisch und damit unabhängig vom Hauptantrieb sowie vom Direktantrieb des Formzylinders antreibt. Dann, wenn nicht nur dem Feuchtwerk sondern auch dem Farbwerk der Druckwerke jeweils ein separater Direktantrieb zugeordnet ist, können auch Rückwirkungen des Farbwerkantriebs auf die Zylinder des Druckwerks vermieden werden, wodurch durch Drehmomentschwankungen verursachte Druckqualitätsstörungen weiter reduziert werden können.According to an advantageous embodiment of the invention, the inking unit of the printing units in each case at least one separate direct drive is assigned, which drives the inking unit in the continuous printing mode self-propelled and thus independent of the main drive and the direct drive of the forme cylinder. Then, when not only the dampening unit but also the inking unit of the printing units each has a separate direct drive, also repercussions of the inking unit drive can be avoided on the cylinders of the printing unit, which caused by torque fluctuations Druckqualitätsstörungen can be further reduced.

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

Preferred embodiments of the invention will become apparent from the dependent claims and the description below. An embodiment of the invention will be described, without being limited thereto, with reference to the drawing. Showing:
Fig. 1:
a highly schematic section of an inventive ß en printing machine in the range of a printing unit.

Fig. 1 zeigt stark schematisiert ein Druckwerk einer als Bogendruckmaschine ausgebildeten Druckmaschine, wobei das Druckwerk der Fig. 1 einen Formzylinder 1, einen auf dem Formzylinder 1 abrollenden Gummizylinder 2 und einen aus dem Gummizylinder 2 abrollenden Gegendruckzylinder 3 umfasst. Der Formzylinder 1 wird auch als Plattenzylinder und der Gummizylinder 2 als Übertragungszylinder bezeichnet. Neben diesen Zylindern 1, 2 und 3 verfügt das Druckwerk der Fig. 1 weiterhin über ein Farbwerk 4 und ein Feuchtwerk 5. Vom Farbwerk 4 sind Farbauftragwalzen und vom Feuchtwerk 5 ist eine Feuchtauftragwalze gezeigt. Fig. 1 shows a highly schematic of a printing unit designed as a sheet-fed press printing machine, wherein the printing of the Fig. 1 a forme cylinder 1, a rolling on the forme cylinder 1 blanket cylinder 2 and a rolling from the blanket cylinder 2 impression cylinder 3 includes. The forme cylinder 1 is also referred to as a plate cylinder and the blanket cylinder 2 as a transfer cylinder. In addition to these cylinders 1, 2 and 3, the printing unit has the Fig. 1 Furthermore, an inking unit 4 and a dampening unit 5. From the inking unit 4 are inking rollers and the dampening unit 5 is a dampening roller shown.

Zumindest der Gegendruckzylinder 3 und der Gummizylinder 2 des Druckwerks der Fig. 1 sind von einem Hauptantrieb 6 antreibbar. Dem Übertragungszylinder 1 ist ein Direktantrieb 7 zugeordnet, um den Formzylinder 1 eigenmotorisch anzutreiben. Bei dem in Fig. 1 gezeigten Druckwerk werden unter Fortdruckbedingungen der Gummizylinder 2, der Gegendruckzylinder 3 sowie das Farbwerk 4 vom Hauptantrieb 6 angetrieben. Der Plattenzylinder 1 wird vom Direktantrieb 7 eigenmotorisch angetrieben, und zwar synchron zum Gummizylinder 2.At least the impression cylinder 3 and the blanket cylinder 2 of the printing of the Fig. 1 are driven by a main drive 6. The transfer cylinder 1 is associated with a direct drive 7 to drive the forme cylinder 1 own motor. At the in Fig. 1 shown printing unit are driven under conditions of continuous printing of the blanket cylinder 2, the impression cylinder 3 and the inking unit 4 from the main drive 6. The plate cylinder 1 is driven by the direct drive 7 eigenmotorisch, in synchronism with the blanket cylinder. 2

Im Sinne der hier vorliegenden Erfindung ist im Feuchtwerk 5 ein separater Direktantrieb zugeordnet, der dass Feuchtwerk 5 unter Fortdruckbedingungen eigenmotorisch und damit unabhängig vom Hauptantrieb 6 der Druckmaschine und vom Direktantrieb 7 des Formzylinders 1 des jeweiligen Druckwerks antreibt. Dabei ist der Direktantrieb 8 des Feuchtwerks 5 vorzugsweise der Feuchtauftragwalze des Feuchtwerks 5 zugeordnet, der dann die Feuchtauftragwalze im Fortdruckbetrieb eigenmotorisch antreibt. Die Feuchtauftragwalze des Feuchtwerks 5 kann dabei vom Direktantrieb 8 derart angetrieben werden, dass die Umfangsgeschwindigkeit der Feuchtauftragwalze entweder der Umfangsgeschwindigkeit des Formzylinders 1 entspricht oder von derselben abweicht.For the purposes of the present invention, a separate direct drive is associated with the dampening unit 5, which drives the dampening unit 5 under conditions of production intrinsic motor and thus independently of the main drive 6 of the printing press and the direct drive 7 of the forme cylinder 1 of the respective printing unit. In this case, the direct drive 8 of the dampening unit 5 is preferably associated with the dampening form roller of the dampening unit 5, which then drives the dampening form roller in the production mode on its own. The dampening roller of the dampening unit 5 can be driven by the direct drive 8 so that the peripheral speed of the dampening roller either corresponds to the peripheral speed of the forme cylinder 1 or deviates from the same.

Bedingt dadurch, dass dem Feuchtwerk 5, insbesondere der Feuchtauftragwalze des Feuchtwerks 5, ein Direktantrieb zugeordnet ist, besteht keine Rückwirkung des Feuchtwerkantriebs bzw. Feuchtauftragwalzenantriebs auf die Zylinder 1, 2 und 3 des Druckwerks. Durch Drehmomentschwankungen verursachte Druckqualitätsstörungen können so reduziert bzw. vermieden werden.Due to the fact that the dampening unit 5, in particular the dampening roller of the dampening unit 5, a direct drive is assigned, there is no reaction of the dampening unit drive or dampening roller drive on the cylinders 1, 2 and 3 of the printing unit. Pressure disturbances caused by torque fluctuations can thus be reduced or avoided.

Der Feuchtauftragwalze des Feuchtwerks 5 kann eine Kupplung zugeordnet sein, die im Fortdruckbetrieb zum Auskuppeln der Feuchtauftragwalze und damit des Feuchtwerks 5 vom Hauptantrieb 6 geöffnet ist, die jedoch in einem Notbetrieb geschlossen werden kann, um z. B. bei einem Ausfall des dem Feuchtwerk 5 zugeordneten Direktantriebs 8 das Feuchtwerk 5 vom Hauptantrieb 6 aus antreiben zu können.The dampening roller of the dampening unit 5 may be associated with a clutch that is open in the continuous printing operation for disengaging the dampening roller and thus the dampening unit 5 from the main drive 6, but which can be closed in an emergency operation to z. B. in case of failure of the dampening unit 5 associated direct drive 8 to be able to drive the dampening unit 5 from the main drive 6 from.

Nach einer vorteilhaften Weiterbildung der hier vorliegenden Erfindung kann vorgesehen sein, dass auch dem Farbwerk 4 eines jeden Druckwerks mindestens ein separater Direktantrieb zugeordnet ist, um das Farbwerk 4 im Fortdruckbetrieb eigenmotorisch und damit unabhängig vom Hauptantrieb 6 der Druckmaschine sowie vom Direktantrieb 7 des Formzylinders 1 anzutreiben.According to an advantageous development of the present invention, it can be provided that at least one separate direct drive is assigned to the inking unit 4 of each printing unit in order to drive the inking unit 4 self-propelled in the continuous printing mode and thus independently of the main drive 6 of the printing press and of the direct drive 7 of the forme cylinder 1 ,

So ist es z. B. möglich, einer Farbauftragwalze des Farbwerks 4 einen separaten Direktantrieb zuzuordnen, der dann die oder jede Farbauftragwalze im Fortdruckbetrieb eigenmotorisch antreibt. Ebenso ist es möglich, einer changierenden Farbreiberwalze einen separaten Direktantrieb zuzuordnen, der dann die Farbreiberwalze im Fortdruckbetrieb eigenmotorisch antreibt. Ebenso kann einer Farbheberwalze ein separater Direktantrieb zugeordnet sein, um im Fortdruckbetrieb die Farbheberwalze eigenmotorisch anzutreiben. Hierdurch ist es möglich, eine Rückwirkung des Farbwerkantriebs auf die Zylinder 1, 2 und 3 des jeweiligen Druckwerks auszuschließen und so durch Drehmomentschwankungen verursachte Druckqualitätsstörungen weiter zu verringern bzw. zu vermeiden. Auch dem Farbwerk 4 kann eine Kupplung zugeordnet sein, die im Fortdruckbetrieb dann, wenn das Farbwerk 4 eigenmotorisch angetrieben wird, geöffnet ist, die hingegen in einem Notbetrieb geschlossen werden kann, um das Farbwerk 4 wieder an den Hauptantrieb 6 der Druckmaschine anzukoppeln.So it is z. B. possible to assign a inking roller of the inking unit 4 a separate direct drive, which then drives the or each inking roller in the production mode self-powered. Likewise, it is possible to associate a variable inking roller with a separate direct drive, which then drives the inking roller in the continuous printing mode on its own. Likewise, a Farbheberwalze be associated with a separate direct drive to drive in the continuous printing operation, the ink fountain roller own motor. This makes it possible to exclude a retroactive effect of the inking unit drive on the cylinders 1, 2 and 3 of the respective printing unit and thus further reduce or avoid printing quality disturbances caused by torque fluctuations. Also, the inking unit 4 may be associated with a clutch that is in the continuous printing operation when the inking unit 4 is driven by an engine is opened, however, can be closed in an emergency operation to couple the inking unit 4 again to the main drive 6 of the printing press.
