Description

Die Erfindung betrifft eine Druckeinheit gemäß dem Oberbegriff der Ansprüche 1 und 6.The invention relates to a printing unit according to the Preamble of claims 1 and 6.

Durch die EP 0 644 048 A2 ist eine Rotationsdruckmaschine mit Gummi- und Plattenzylindern bekannt. Diese Gummi- und Plattenzylinder sind paarweise durch eine mechanische Kopplung für ihren gemeinsamen Antrieb zu Zylindergruppen zusammengefaßt. Eine solche Zylindergruppe wird jeweils von einem eigenen Antriebsmotor angetrieben.EP 0 644 048 A2 is one Rotary printing machine with rubber and plate cylinders known. These rubber and plate cylinders are in pairs through a mechanical coupling for their common Drive grouped into cylinder groups. Such Cylinder group is each of its own Drive motor driven.

Der Erfindung liegt die Aufgabe zugrunde, eine Druckeinheit zu schaffen.The invention has for its object a To create printing unit.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teiles der Ansprüche 1 und 6 gelöst.This object is achieved by the features of the characterizing part of claims 1 and 6 solved.

In vorteilhafter weise entfallen bei der erfindungsgemäßen Druckeinheit mechanische Vorrichtungen zum Verstellen der Umfangsregister. Wird mittels des getrennten Antriebes der Plattenzylinder eine Verstellung des Umfangsregister durchgeführt, indem eine Phasenlage der Plattenzylinder relativ zueinander verändert wird, bleibt eine relative Drehwinkellage der Gummizylinder zueinander gleich. Kanäle der Gummizylinder verbleiben relativ zueinander in gleicher Stellung. Eine Stellung eines Kanals eines Plattenzylinders verändert sich zwar zu dem Kanal des zugehörigen Gummizylinders, aber da der Kanal (d.h. ein nichtdruckender Bereich) des Plattenzylinders üblicherweise kleiner ist als der Kanal des zugehörigen Gummizylinders, geht der Kanal des Plattenzylinders nicht über den Bereich des Kanals des Gummizylinders hinaus.
Somit vergrößert sich auch bei Verstellung des Umfangsregisters der nichtdruckende Bereich infolge der Kanäle der Gummizylinder nicht.
Im Vergleich zu Druckeinheiten deren Zylinder jeweils einen eigenen Einzelantrieb aufweisen, ist der Aufwand der elektrischen Ausstattung wesentlich geringer. Zusätzlich kann durch die wahlweise Kopplung eines Plattenzylinders an die Gummizylinder ein zweiter Plattenzylinder beispielsweise für einen Plattenwechsel stillgesetzt werden.Mechanical devices for adjusting the circumferential registers are advantageously dispensed with in the printing unit according to the invention. If the circumferential register is adjusted by means of the separate drive of the plate cylinder by changing a phase position of the plate cylinder relative to one another, a relative angle of rotation position of the rubber cylinders relative to one another remains the same. Channels of the rubber cylinders remain in the same position relative to each other. A position of a channel of a plate cylinder changes relative to the channel of the associated blanket cylinder, but since the channel (ie a non-printing area) of the plate cylinder is usually smaller than the channel of the associated blanket cylinder, the channel of the plate cylinder does not go beyond the area of the channel of the Rubber cylinder out.
Thus, even when the circumferential register is adjusted, the non-printing area does not increase due to the channels of the rubber cylinders.
Compared to printing units whose cylinders each have their own individual drive, the outlay on the electrical equipment is considerably less. In addition, by optionally coupling a plate cylinder to the blanket cylinder, a second plate cylinder can be stopped, for example for a plate change.

Die Druckeinheit ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.The printing unit is shown in the drawing and is described in more detail below.

Im vorliegenden Ausführungsbeispiel ist eine Druckeinheit 1 einer Offsetrotationsdruckmaschine in sogenannter Brückenbauweise dargestellt. Diese Druckeinheit 1 wird im wesentlichen von zwei Form- und Übertragungszylindern 2, 3, 4, 6, z. B. Platten- und Gummizylindern 2, 3, 4, 6 gebildet, die paarweise zusammenwirken. Die beiden Gummizylinder 4, 6 bilden in ihrer Berührzone eine Druckstelle 7, in der beispielsweise eine Papierbahn 8 bedruckt wird.
Diese Platten- und Gummizylinder 2, 3, 4, 6 sind an beiden Enden mit Zapfen 9, 11 - 14, 16-18 versehen, die in Seitengestellen 19, 21 der Offsetrotationsdruckmaschine gelagert sind. Platten- und Gummizylinder 2, 3, 4, 6 sind in bekannter Weise, beispielsweise mittels Exzenterbüchsen, an- und abstellbar angeordnet. Beispielsweise können die Plattenzylinder 2, 3 bezüglich der zugehörigen Gummizylinder 4, 6 an- und abstellbar angeordnet sein.
An einer Antriebsseite der Druckeinheit 1 reichen die Zapfen 9, 12, 14, 17 der Platten- und Gummizylinder 2, 3, 4, 6 durch das Seitengestell 19. Die Zapfen 14, 17 der beiden Gummizylinder 4, 6 und des ersten Plattenzylinders 2 sind mit zusammenwirkenden Zahnrädern 22, 23, 24 versehen. Diese drei Zylinder 2, 4, 6 werden von einem gemeinsamen Antrieb 26, beispielsweise einem lagegeregelten Elektromotor 26 angetrieben. Dieser Elektromotor 26 ist beispielsweise direkt an dem ersten Plattenzylinder 2 angeordnet, aber der Antrieb 26 kann auch an jedem beliebigen der drei Zylinder 2, 4, 6 direkt oder indirekt vorgesehen sein.
Der zweite Plattenzylinder 3 ist mit einem eigenen Antrieb 27 versehen, der beispielsweise als lagegeregelter Elektromotor 27 ausgeführt ist.
Der Antrieb 26 der drei Zylinder 2, 4, 6 und der Antrieb 27 des zweiten Plattenzylinders 3 sind zueinander synchronisiert.In the present exemplary embodiment, a printing unit 1 of an offset rotary printing press is shown in a so-called bridge construction. This printing unit 1 is essentially two forme and transfer cylinders 2, 3, 4, 6, z. B. plate and rubber cylinders 2, 3, 4, 6 formed, which interact in pairs. The two rubber cylinders 4, 6 form a printing point 7 in their contact zone, in which, for example, a paper web 8 is printed.
These plate and blanket cylinders 2, 3, 4, 6 are provided at both ends with pins 9, 11 - 14, 16-18, which are mounted in side frames 19, 21 of the offset rotary printing press. Plate and rubber cylinders 2, 3, 4, 6 are arranged in a known manner, for example by means of eccentric bushes, on and off. For example, the plate cylinders 2, 3 can be arranged on and off with respect to the associated rubber cylinders 4, 6.
On a drive side of the printing unit 1, the pins 9, 12, 14, 17 of the plate and rubber cylinders 2, 3, 4, 6 extend through the side frame 19. The pins 14, 17 of the two rubber cylinders 4, 6 and the first plate cylinder 2 are provided with cooperating gears 22, 23, 24. These three cylinders 2, 4, 6 are driven by a common drive 26, for example a position-controlled electric motor 26. This electric motor 26 is arranged, for example, directly on the first plate cylinder 2, but the drive 26 can also be provided on any of the three cylinders 2, 4, 6 directly or indirectly.
The second plate cylinder 3 is provided with its own drive 27, which is designed, for example, as a position-controlled electric motor 27.
The drive 26 of the three cylinders 2, 4, 6 and the drive 27 of the second plate cylinder 3 are synchronized with each other.

Es ist möglich, an einen der beiden Gummizylinder 4, 6 ein drittes Paar Platten- und Gummizylinder anzustellen.
Dabei bildet der dritte Gummizylinder mit dem zweiten oder ersten Gummizylinder eine zweite Druckstelle. Auch der dritte Gummizylinder ist dann mit einem Zahnrad versehen. das z. B. in das Zahnrad des zusammenwirkenden Gummizylinders eingreift. Der dritte Gummizylinder ist mechanisch, z. B. formschlüssig an den ersten und zweiten Gummizylinder sowie an den ersten Plattenzylinder gekoppelt.
Der dritte Plattenzylinder ist wiederum mit einem eigenen lagegeregelten Elektromotor versehen.It is possible to place a third pair of plate and rubber cylinders on one of the two rubber cylinders 4, 6.
The third rubber cylinder forms a second pressure point with the second or first rubber cylinder. The third rubber cylinder is then also provided with a gear. the Z. B. engages in the gear of the interacting rubber cylinder. The third blanket cylinder is mechanical, e.g. B. positively coupled to the first and second rubber cylinders and to the first plate cylinder.
The third plate cylinder is in turn provided with its own position-controlled electric motor.

In einem weiteren Ausführungsbeispiel wirken die Gummizylinder nicht direkt zusammen, sondern es ist ein zusätzlicher Druckzylinder, ein sogenannter Satellitenzylinder, vorgesehen. Mit diesem Druckzylinder bildet jeder angestellte Gummizylinder eine Druckstelle. Dieser Druckzylinder ist vorzugsweise mit einem Zahnrad versehen, das in ein Zahnrad eines Gummizylinders eingreift. Somit ist der Druckzylinder mechanisch, z. B. formschlüssig an einen Gummizylinder gekoppelt. Auch ist es möglich den Druckzylinder mit einem eigenen unabhängigen Antrieb, z. B. einem lagegeregelten Elektromotor zu versehen.In another embodiment, the Rubber cylinders are not directly together, but it is a additional pressure cylinder, a so-called Satellite cylinder, provided. With this pressure cylinder each employed rubber cylinder forms a pressure point. This pressure cylinder is preferably with a gear provided that in a gear of a rubber cylinder intervenes. Thus, the pressure cylinder is mechanical, e.g. B. positively coupled to a rubber cylinder. Is too it is possible to have the printing cylinder with its own independent drive, e.g. B. a position-controlled To provide electric motor.

Anstelle der Zahnräder 22, 23, 24 können zur mechanischen Kopplung, z. B. zur formschlüssigen Antriebsverbindung der Zylinder 2, 4, 6 auch andere Mittel, wie Z. B. Zahnriemen, vorgesehen sein.Instead of the gears 22, 23, 24 can mechanical coupling, e.g. B. for positive Drive connection of cylinders 2, 4, 6 also others Means, such as toothed belts, can be provided.

Das Zahnrad 22 des Plattenzylinders 2 kann beispielsweise auch vom Zahnrad 23 des zugehörigen Gummizylinders 4 entkoppelbar sein. Zu diesem Zweck kann das Zahnrad 22 axial verschiebbar auf dem Zapfen 9 des Plattenzylinders 2 gelagert sein, so daß es bezüglich des Zahnrades 23 des Gummizylinders 4 außer Eingriff bringbar ist.
Auf dem Zapfen 12 des zweiten Plattenzylinders 3 kann auch ein Zahnrad 28 angeordnet sein, das wahlweise mit dem Zahnrad 24 des zugeordneten Gummizylinders 6 in Eingriff bringbar ist. Dieses Zahnrad 28 ist dazu verschiebbar auf dem Zapfen 12 des Plattenzylinders 3 gelagert.
Somit ist es möglich, wahlweise einen der beiden Plattenzylinder 2 bzw. 3 an die beiden Gummizylinder 4, 6 mechanisch zu koppeln, d. h. in formschlüssige Antriebsverbindung zu bringen, während der andere Plattenzylinder 2 bzw. 3 von den Gummizylindern 4, 6 entkoppelt ist. Dieser zweite Plattenzylinder 2 bzw. 3 kann von dem zugehörigen Gummizylinder 4 bzw. 6 um beispielsweise einen Plattenwechsel durchzuführen, abgestellt werden und somit stillgesetzt werden, während der andere Plattenzylinder 2 bzw. 3 mit den beiden Gummizylindern 4, 6 die Papierbahn 8 bedruckt. The gear 22 of the plate cylinder 2 can for example also be uncoupled from the gear 23 of the associated rubber cylinder 4. For this purpose, the gear 22 can be mounted axially displaceably on the pin 9 of the plate cylinder 2, so that it can be disengaged with respect to the gear 23 of the rubber cylinder 4.
A gear 28 can also be arranged on the pin 12 of the second plate cylinder 3, which gear can optionally be brought into engagement with the gear 24 of the associated rubber cylinder 6. This gear 28 is slidably mounted on the pin 12 of the plate cylinder 3.
It is thus possible to mechanically couple one of the two plate cylinders 2 or 3 to the two rubber cylinders 4, 6, ie to bring them into a form-fitting drive connection, while the other plate cylinder 2 or 3 is decoupled from the rubber cylinders 4, 6. This second plate cylinder 2 or 3 can be stopped by the associated rubber cylinder 4 or 6, for example in order to carry out a plate change, and thus shut down, while the other plate cylinder 2 or 3 with the two rubber cylinders 4, 6 prints on the paper web 8.
