Description

Die Erfindung betrifft ein Druckwerk einer Druckeinheit einer Druckmaschine gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a printing unit of a printing unit of a printing press according to the preamble of claim 1.

Druckeinheiten von Rollenrotationsdruckmaschinen, insbesondere von Zeitungsdruckmaschinen oder auch lllustrationsdruckmaschinen, verfügen üblicherweise über mehrere Druckwerke, wobei jedes Druckwerk zumindest einen Übertragungszylinder, einen Formzylinder und ein Farbwerk sowie vorzugsweise ein Feuchtwerk umfasst. Es sind auch Druckwerke ohne Feuchtwerk bekannt. Weiterhin können solche Druckeinheiten Gegendruckzylinder, die auch als Satellitenzylinder bezeichnet werden, aufweisen, wobei ein solcher Gegendruckzylinder mit einem oder mehreren Übertragungszylindern unterschiedlicher Druckwerke zusammenwirken kann. Neben Druckeinheiten, die derartige Gegendruckzylinder aufweisen, sind auch Druckeinheiten bekannt, die keine Gegendruckzylinder aufweisen, wobei bei solchen Druckeinheiten ohne Gegendruckzylinder die Übertragungszylinder zweier Druckwerke aufeinander abrollen. Die Übertragungszylinder werden auch als Gummizylinder und die Formzylinder auch als Plattenzylinder bezeichnet werden. Die Formzylinder bzw. Plattenzylinder tragen Druckformen.Printing units of web-fed rotary printing presses, in particular newsprint or also illustration printing presses, usually have a plurality of printing units, each printing unit comprising at least one transfer cylinder, a forme cylinder and an inking unit, and preferably a dampening unit. There are also printing units without dampening known. Furthermore, such printing units counter-pressure cylinder, which are also referred to as a satellite cylinder, have, wherein such an impression cylinder can interact with one or more transfer cylinders of different printing units. In addition to printing units which have such counter-pressure cylinders, printing units are also known which do not have counter-pressure cylinders, with such printing units without counterpressure cylinders unrolling the transfer cylinders of two printing couples. The transfer cylinders are also referred to as rubber cylinders and the form cylinder as a plate cylinder. The form cylinder or plate cylinder carry printing forms.

Der Übertragungszylinder, der Formzylinder sowie Walzen des Farbwerks sowie gegebenenfalls Feuchtwerks eines Druckwerks sind antriebsseitig über Zahnräder gekoppelt und stehen demnach untereinander über die Zahnräder in einer mechanischen Antriebsverbindung. In der EP 1 392 510 B1 wird vorgeschlagen, die Zahnräder, über welche der Übertragungszylinder und der Formzylinder eines Druckwerks miteinander gekoppelt sind, als schrägverzahnte Zahnräder auszuführen. Wird bei einem solchen Druckwerk zur Seitenregisterverstellung der Formzylinder und/oder das dem Formzylinder zugeordnete, schrägverzahnte Zahnrad in Axialrichtung verschoben, so erfolgt zwangsläufig auch eine Verdrehung der miteinander gekoppelten, schrägverzahnten Zahnräder, wobei diese Verdrehung der Zahnräder nach der EP 1 392 510 B1 durch eine Umfangskorrektur mit dem Antriebsmotor ausgeglichen werden muss. Dies ist aufwendig und demnach von Nachteil.The transfer cylinder, the forme cylinder and rollers of the inking unit and optionally dampening units of a printing unit are coupled on the drive side via gears and are therefore mutually connected via the gears in a mechanical drive connection. In the EP 1 392 510 B1 It is proposed that the gears, over which the transfer cylinder and the forme cylinder of a printing unit are coupled together, to perform as helical gears. If the form cylinder and / or the helical gearwheel associated with the forme cylinder are displaced in the axial direction in such a printing unit for lateral register adjustment, a rotation of the one another is inevitably also effected coupled, helical gears, said rotation of the gears after the EP 1 392 510 B1 must be compensated by a circumferential correction with the drive motor. This is expensive and therefore disadvantageous.

Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zugrunde, ein neuartiges Druckwerk zu schaffen. Dieses Problem wird durch ein Druckwerk gemäß Anspruch 1 gelöst. Erfindungsgemäß sind die Zahnräder in mehreren Zahnradebenen angeordnet, derart, dass in einer ersten Zahnradebene ausschließlich geradverzahnte Zahnräder angeordnet sind, wobei die Zahnräder der ersten Zahnradebene den Übertragungszylinder an den Formzylinder und den Formzylinder an mindestens eine anzutreibende Walze von Farbwerk und vorzugsweise Feuchtwerk koppeln, und dass in einer zweiten Zahnradebene ausschließlich schrägverzahnte Zahnräder angeordnet sind, wobei die Zahnräder der zweiten Zahnradebene einen Antriebsmotor an den Übertragungszylinder koppeln.On this basis, the present invention is based on the problem to provide a novel printing unit. This problem is solved by a printing unit according to claim 1. According to the invention, the gears are arranged in several gear levels, such that only spur gears are arranged in a first gear plane, wherein the gears of the first gear plane couple the transfer cylinder to the forme cylinder and the forme cylinder to at least one roller of inking unit and preferably dampening unit to be driven, and in a second gear plane exclusively helical gears are arranged, wherein the gears of the second gear level coupling a drive motor to the transfer cylinder.

Bei dem erfindungsgemäßen Druckwerk wird bei einer Seitenregisterverstellung am Formzylinder durch axiale Bewegung des Formzylinders zusammen mit dem geradverzahnten Zahnrad desselben keine Umfangskorrektur am Antriebsmotor oder anderen zusätzlichen, separaten Verstelleinheiten notwendig. Die erste Zahnradebene mit den geradverzahnten Zahnrädern erstreckt sich durchgängig vom Übertragungszylinder bis zum Farbwerk und gegebenenfalls Feuchtwerk. Bei dem erfindungsgemäßen Druckwerk ist die Anzahl der benötigten Zahnräder ebenso wie die Anzahl der Zahnradebenen, in welchen die Zahnräder angeordnet sind, minimiert, wodurch einerseits der benötigte Bauraum minimiert werden kann, und wodurch andererseits Kosten reduziert werden können.In the printing unit according to the invention is at a side register adjustment on the forme cylinder by axial movement of the forme cylinder together with the spur gear of the same no circumferential correction on the drive motor or other additional, separate adjustment necessary. The first gear plane with the spur gears extends continuously from the transfer cylinder to the inking unit and optionally dampening unit. In the printing unit according to the invention, the number of required gears as well as the number of gear levels in which the gears are arranged, minimized, whereby on the one hand the required space can be minimized, and on the other hand, costs can be reduced.

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:

Fig. 1 zeigt einen schematisierten Querschnitt durch ein erfindungsgemäßes Druckwerk 10 einer Druckeinheit einer Druckmaschine, nämlich einer Rollenrotationsdruckmaschine. So sind im Querschnitt der Fig. 1 ein Übertragungszylinder 11, ein auf dem Übertragungszylinder 11 abrollender Formzylinder 12, eine auf dem Formzylinder 12 abrollende Farbauftragwalze 13 eines Farbwerks sowie eine auf der Farbauftragwalze 13 abrollende weitere Walze 14 des Farbwerks gezeigt. Die Walze 14 ist vorzugsweise eine Reiberwalze des Farbwerks. Neben der in Fig. 1 gezeigten Farbauftragwalze 13 kann auf dem Formzylinder 12 mindestens eine weitere Farbauftragwalze des Farbwerks sowie mindestens eine Feuchtauftragwalze eines Feuchtwerks abrollen.Fig. 1 shows a schematic cross section through an inventive printing unit 10 of a printing unit of a printing press, namely a web-fed rotary printing machine. 1, a transfer cylinder 11, a form cylinder 12 rolling on the transfer cylinder 11, an inking roller 13 of an inking unit rolling on the forme cylinder 12 and an additional roller 14 of the inking unit rolling on the inking roller 13 are shown. The roller 14 is preferably a distributor roller of the inking unit. In addition to the inking roller 13 shown in FIG. 1, at least one further inking roller of the inking unit and at least one dampening roller of a dampening unit can roll on the forme cylinder 12.

Die in Fig. 1 dargestellten Zylinder 11 und 12 sowie die Walze 14 des Druckwerks 10 sind über Zahnräder antriebsseitig gekoppelt, wobei die Zahnräder in zwei Zahnradebenen 15 und 16 angeordnet sind. Die Farbauftragwalze 13 wird über Friktion bzw. Reibung mit dem Formzylinder 12 und der Walze 14 angetrieben. Die Farbauftragwalze 13 ist demnach nicht über ein Zahnrad antriebsseitig mit dem Formzylinder 12 und der Walze 14 gekoppelt.The cylinders 11 and 12 shown in Fig. 1 and the roller 14 of the printing unit 10 are coupled via gears on the drive side, wherein the gears are arranged in two gear levels 15 and 16. The inking roller 13 is driven by friction with the forme cylinder 12 and the roller 14. The inking roller 13 is therefore not coupled via a gear on the drive side with the forme cylinder 12 and the roller 14.

In einer ersten Zahnradebene 15 sind ausschließlich geradverzahnte Zahnräder angeordnet, nämlich ein auf einer Achse 17 des Übertragungszylinders 11 angeordnetes, geradverzahntes Zahnrad 18, ein auf einer Achse 19 des Formzylinders 12 angeordnetes, geradverzahntes Zahnrad 20, ein auf einer Achse 21 angeordnetes, geradverzahntes Zahnrad 22, ein auf einer Achse 23 der Walze 14 angeordnetes, geradverzahntes Zahnrad 24 sowie gegebenenfalls weitere Zahnräder 25, die auf Achsen von weiteren Walzen des Farbwerks bzw. eines Feuchtwerks angeordnet sind.In a first gear plane 15 only spur gears are arranged, namely a arranged on an axis 17 of the transfer cylinder 11, spur gear 18, a arranged on an axis 19 of the forme cylinder 12, spur gear 20, a arranged on an axis 21, spur gear 22nd , a spur gear 24 arranged on an axis 23 of the roller 14 and possibly further gear wheels 25 which are arranged on axles of further rollers of the inking unit or of a dampening unit.

Über das auf der Achse 17 des Übertragungszylinders 11 positionierte, in der ersten Zahnradebene 15 angeordnete, geradverzahnte Zahnrad 18 ist der Übertragungszylinder 11 mit dem ebenfalls in der ersten Zahnradebene 15 positionierten, auf der Achse 19 des Formzylinders 12 angeordneten Zahnrad 20 gekoppelt. Dieses geradverzahnte Zahnrad 20 des Formzylinders 12 ist mit dem geradverzahnten Zahnrad 22 gekoppelt, welches auf der Achse 21 gelagert ist, wobei es sich bei der Achse 21 nicht um die Achse der Farbauftragwalze 13 handelt. Alle unmittelbar nebeneinander angeordneten Zahnräder der ersten Zahnradebene 15 sind demnach antriebsseitig gekoppelt.About the arranged on the axis 17 of the transfer cylinder 11, arranged in the first gear plane 15, spur gear 18 of the transfer cylinder 11 is also coupled to the in the first gear plane 15, arranged on the axis 19 of the forme cylinder 12 gear 20. This spur gear 20 of the forme cylinder 12 is coupled to the spur gear 22, which is mounted on the axle 21, wherein the axis 21 is not the axis of the inking roller 13. All immediately adjacent gears of the first gear level 15 are therefore coupled on the drive side.

In der zweiten Zahnradebene 16 sind ausschließlich schrägverzahnte Zahnräder angeordnet, nämlich ein auf der Achse 17 des Übertragungszylinders 11 angeordnetes, schrägverzahntes Zahnrad 26 sowie ein schrägverzahntes Zahnrad 27, welches gemäß Fig. 1 auf einer Welle 28 eines Antriebsmotors 29 positioniert ist. Die beiden schrägverzahnten Zahnräder 26 und 27 der zweiten Zahnradebene 16 sind antriebsseitig gekoppelt und stehen in Eingriff miteinander.In the second gear plane 16 exclusively helical gears are arranged, namely a arranged on the axis 17 of the transfer cylinder 11, helical gear 26 and a helical gear 27, which is positioned as shown in FIG. 1 on a shaft 28 of a drive motor 29. The two helical gears 26 and 27 of the second gear level 16 are coupled on the drive side and are engaged with each other.

Im Unterscheid zur Fig. 1 ist es auch möglich, dass das schrägverzahnte Zahnrad 27 auf einer separaten Achse angeordnet und über eine Ausgleichkupplung mit der Welle des Antriebsmotors gekoppelt ist.In contrast to Fig. 1, it is also possible that the helical gear 27 is arranged on a separate axis and coupled via a compensating coupling with the shaft of the drive motor.

Bei dem in Fig. 1 dargestellten Druckwerk 10 sind demnach ausschließlich auf der Achse 17 des Übertragungszylinders 11 zwei Zahnräder positioniert, nämlich einerseits das in der ersten Zahnradebene 15 angeordnete, geradverzahnte Zahnrad 18 sowie das in der zweiten Zahnradebene 16 angeordnete, schrägverzahnte Zahnrad 26. Auf den anderen Achsen der Zylinder bzw. Walzen des Druckwerks sowie auf der Welle des Antriebsmotors ist jeweils lediglich ein Zahnrad positioniert. Die komplette mechanische Kopplung aller anzutreibenden Zylinder bzw. Walzen des Druckwerks 10 erfolgt über die beiden Zahnradebenen 15 und 16. Hierdurch ergibt sich eine Minimierung des benötigten Bauraums sowie eine Minimierung der benötigten Zahnräder.In the case of the printing unit 10 shown in FIG. 1, therefore, two toothed wheels are positioned exclusively on the axis 17 of the transfer cylinder 11, namely the spur gear 18 arranged in the first gear plane 15 and the helical gear 26 arranged in the second gear plane 16 the other axes of the cylinders or rollers of the printing unit and on the shaft of the drive motor only one gear is positioned in each case. The complete mechanical coupling of all driven cylinders or rollers of the printing unit 10 via the two gear levels 15 and 16. This results in a minimization of the required space and a minimization of the required gears.

Soll zur Seitenregisterverstellung der Formzylinder 12 in Richtung des Doppelpfeils 30 zusammen mit dem geradverzahnten Zahnrad 20 in Axialrichtung verschoben werden, so hat dies bedingt durch die Geradverzahnung innerhalb der ersten Zahnradebene 15 keine Drehbewegung an den Zahnrädern zur Folge und es muss dann auch keine Umfangskorrektur am Antriebsmotor 29 oder einer anderen Umfangsregisterverstelleinheit vorgenommen werden.If the forme register adjustment of the forme cylinder 12 in the direction of the double arrow 30 is to be displaced together with the spur gear 20 in the axial direction, then this has no rotational movement on the gears due to the spur gear within the first gear plane 15 and then no circumferential correction on the drive motor 29 or another Umfangsregisterverstelleinheit be made.

Das in Fig. 1 dargestellte Druckwerk 10 kann in allen bekannten Bauformen von Druckeinheiten einer Rollenrotationsdruckmaschine zum Einsatz kommen. So ist es z. B. möglich, bei einer 8-Zylinder-Druckeinheit vier der in Fig. 1 dargestellten Druckwerke 10 zu verwenden, wobei dann jedem Druckwerk der 8-Zylinder-Druckeinheit ein separater Antrieb zugeordnet ist.The printing unit 10 shown in FIG. 1 can be used in all known types of printing units of a web-fed rotary printing press. So it is z. B. possible to use in an 8-cylinder printing unit four of the printing units 10 shown in FIG. 1, in which case each printing unit of the 8-cylinder printing unit is assigned a separate drive.

Ebenso ist es möglich, für jeweils zwei Druckwerke einer 8-Zylinder-Druckeinheit lediglich einen gemeinsamen Antriebsmotor vorzusehen, wobei dann in diesem Fall die schrägverzahnten Zahnräder 26 der Übertragungszylinder 11 von jeweils zwei Druckwerken miteinander in Eingriff stehen, um so die Übertragungszylinder 11 von zwei Druckwerken 10 über einen Antrieb 29 anzutreiben.It is also possible to provide only a common drive motor for every two printing units of an 8-cylinder printing unit, in which case the helical gears 26 of the transfer cylinder 11 of two printing units are engaged with each other, so as to transfer cylinders 11 of two printing units 10 to drive via a drive 29.

Ebenso ist es möglich, das erfindungsgemäße Druckwerk 10 bei sogenannten Satelliten-Druckeinheiten einzusetzen. Derartige Satelliten-Druckeinheiten können als 9-Zylinder-Druckeinheit mit vier Druckwerken und einem einzigen Satellitenzylinder bzw. als 10-Zylinder-Druckeinheit mit vier Druckwerken und zwei Satellitenzylindern ausgebildet sein. Dabei kann dann jedes der Druckwerke einer solchen Satelliten-Druckeinheit gemäß Fig. 1 ausgebildet sein, wobei der oder jeder Satellitenzylinder der Satelliten-Druckeinheiten entweder über einen eigenen Antriebsmotor oder von einem Antriebsmotor eines der Druckwerke aus angetrieben werden kann.It is likewise possible to use the printing unit 10 according to the invention in so-called satellite printing units. Such satellite printing units may be formed as a 9-cylinder printing unit with four printing units and a single satellite cylinder or as a 10-cylinder printing unit with four printing units and two satellite cylinders. In this case, each of the printing units of such a satellite printing unit according to FIG. 1 can be formed, wherein the or each satellite cylinder of the satellite printing units can be driven either by its own drive motor or by a drive motor of one of the printing units.

Auch bei einer solchen Satelliten-Druckeinheit können jeweils zwei Druckwerke und ein Satellitenzylinder von einem gemeinsamen Antrieb aus angetrieben werden, wobei dann die schrägverzahnten Zahnräder der Übertragungszylinder von zwei Druckwerken unter Zwischenschaltung eines schrägverzahnten Zahnrads des Satellitenzylinders miteinander in Eingriff stehen, um so die Übertragungszylinder von zwei Druckwerken und den Satellitenzylinder über einen gemeinsamen Antrieb anzutreiben.Also, in such a satellite printing unit, two printing units and a satellite cylinder can be driven by a common drive, in which case the helical gears of the transfer cylinder of two printing units with the interposition of a helical gear of the satellite cylinder are engaged, so the transfer cylinder of two To drive printing units and the satellite cylinder via a common drive.

Die Verwendung des erfindungsgemäßen Druckwerks 10 ist nicht auf Druckeinheiten mit vier Druckwerken beschränkt, sondern kann vielmehr auch bei Druckeinheiten zum Einsatz kommen, die über drei, zwei oder auch nur ein Druckwerk verfügen. Dann, wenn eine Druckeinheit lediglich ein einziges Druckwerk 10 umfasst, rollt auf dem Übertragungszylinder 11 desselben ein Gegendruckzylinder ab, wobei ein solcher Gegendruckzylinder über ein demselben zugeordnetes Zahnrad, welches mit dem geradverzahnten Zahnrad 18 oder auch mit dem schrägverzahnten Zahnrad 26 des Übertragungszylinders 11 in Eingriff stehen kann, angetrieben wird.The use of the printing unit 10 according to the invention is not limited to printing units with four printing units, but rather can also be used in printing units that have three, two or just a printing unit.
