The arrangement of printing groups can be altered in the direction parallel to the cylinder rotation axes.

Description

Die Erfindung betrifft ein Druckwerk einer Offsetrotationsdruckmaschine gemäß dem Oberbegriff des Anspruchs 1 oder 2.The invention relates to a printing unit of an offset rotary printing press according to the preamble of claim 1 or 2.

Durch die EP 07 49 369 B1 ist eine Druckeinheit für eine Mehrfarbenrollenrotationsdruckmaschine für Schön- und Wiederdruck bekannt, bei dem zwei Druckwerke in sogenannter Brückenbauweise einander gegenüberliegend in einem Rahmen angeordnet sind, wobei die Anordnung der Druckwerke relativ zueinander quer zur Richtung der Rotationsachsen der Zylinder veränderbar ist.By EP 07 49 369 B1 a printing unit for a multi-color roller printing press for fine and reprint is known in which two printing units in so-called bridge construction are arranged opposite each other in a frame, wherein the arrangement of the printing couples relative to each other transversely to the direction of the axes of rotation of the cylinder changeable is.

Eine aus der DE 198 33 468 A1 bekannte Offsetdruckmaschine weist ebenfalls jeweils zwei einander gegenüberliegende Druck auf, die entlang einer senkrechten Trennebene getrennt und abstandsveränderbar angeordnet werden können.A known from DE 198 33 468 A1 offset printing machine also has two opposing pressure, which can be separated along a vertical separation plane and arranged to change the distance.

In der EP 09 58 917 A1 ist eine Rollenrotations-Druckmaschine beschrieben, die mehrere aus jeweils zwei Druckwerken aufgebaute Druckwerke aufweist. Die Druckwerke sind dabei übereinander angeordnet und können entlang einer im wesentlichen horizontal verlaufenden Trennebene getrennt werden. Die einzelnen Druckwerke können vertikal quer zur Rotationsachse der Zylinder verfahren werden, so dass für die Durchführung beispielsweise von Wartungsarbeiten ein Abstand zwischen den einzelnen Druckwerken herstellbar ist.In EP 09 58 917 A1 a web-fed rotary printing press is described which has a plurality of printing units constructed from two printing units each. The printing units are arranged one above the other and can be separated along a substantially horizontally extending parting plane. The individual printing units can be moved vertically transversely to the axis of rotation of the cylinder, so that for the implementation of maintenance, for example, a distance between the individual printing units can be produced.

Aus der EP 06 38 419 B1 ist eine Rollenrotationsdruckmaschine bekannt, deren einzelnen Komponenten, insbesondere die Zylinderelemente und deren zugeordnete Farb- und Feuchtwerke, in einem Traggestell gelagert sind. Die Farb- und Feuchtwerke sind dabei als verfahrbare Einheiten ausgebildet, die in achsparalleler Richtung der Rotationsachsen aus dem Druckwerk ausziehbar sind.From EP 06 38 419 B1, a web-fed rotary printing press is known, the individual components, in particular the cylinder elements and their associated inking and dampening units, are mounted in a support frame. The inking and dampening units are designed as movable units that can be pulled out of the printing unit in the axis-parallel direction of the axes of rotation.

Die DE 199 19 864 C1 offenbart zwei Fünfzylinderdruckeinheiten, die relativ zueinander entweder quer oder längs der Rotationsachse der Zylinder verschiebbar sind.DE 199 19 864 C1 discloses two five-cylinder pressure units, which are displaceable relative to each other either transversely or along the axis of rotation of the cylinder.

Der Erfindung liegt die Aufgabe zugrunde, ein Druckwerk einer Offsetrotationsdruckmaschine zu schaffen.The invention has for its object to provide a printing unit of an offset rotary printing machine.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 oder 2 gelöst.The object is achieved by the features of claim 1 or 2.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass der erforderliche Platzbedarf vor und hinter den jeweils paarweise angeordneten Druckwerken verringert werden kann. Denn zur Durchführung von Wartungsarbeiten müssen die Druckwerke nicht, wie aus dem Stand der Technik bekannt, quer zur Richtung der Rotationsachsen der Zylinder auseinander gefahren werden. Statt dessen werden die Druckwerke in achsparalleler Richtung der Rotationsachsen der Zylinder seitlich versetzt angeordnet, so dass die Druckwerke für die erforderlichen Arbeiten zugänglich werden, ohne dass der Abstand zwischen den Druckwerken quer zur Richtung der Rotationsachsen der Zylinder verändert werden muss. Diese Maßnahme ist insbesondere dann vorteilhaft, wenn mehrere paarweise angeordnete Druckwerke hintereinander angeordnet sind, beispielsweise in der Art von hintereinander angeordneten Drucktürmen, da in diesem Fall die hintereinander angeordneten Druckwerkspaare mit geringerem Abstand zueinander aufgestellt werden können. Ein weiterer Vorteil ergibt sich daraus, dass bestimmte Teile der Druckwerke, nämlich die Teile, die jeweils auf einer Seite eines Druckwerks am weitesten außen liegen, bereits bei einem relativ geringen seitlichen Versatz zwischen den Druckwerken voll zugänglich sind. Dadurch wird es beispielsweise möglich, besonders wartungsintensive Teile der Druckwerke in diesem Bereich der Druckwerke anzuordnen, so dass zur Inspektion bzw. Wartung dieser wartungsintensiven Teile die Druckwerke nicht vollständig auseinander gefahren werden müssen, sondern nur so weit, dass die zu wartenden Teile ausreichend zugänglich sind.The achievable with the present invention consist in particular that the required space can be reduced in front of and behind the paired printing units. Because to perform maintenance work, the printing units must not, as known from the prior art, are moved apart transverse to the direction of the axes of rotation of the cylinder. Instead, the printing units are arranged laterally offset in the axis-parallel direction of the axes of rotation of the cylinder, so that the printing units for the necessary work are accessible without the distance between the printing units must be changed transversely to the direction of the axes of rotation of the cylinder. This measure is particularly advantageous when a plurality of printing couples arranged in pairs are arranged one behind the other, for example in the manner of printing towers arranged one behind the other, since in this case the successively arranged pairs of printing couples can be set up at a smaller distance from each other. Another advantage results from the fact that certain parts of the printing units, namely the parts that are outermost on one side of a printing unit, are fully accessible even with a relatively small lateral offset between the printing units. This makes it possible, for example, to arrange particularly maintenance-intensive parts of the printing units in this area of the printing units, so that the printing units do not have to be completely moved apart to inspect or maintain these maintenance-intensive parts, but only so far that the parts to be serviced are sufficiently accessible ,

Da nicht nur einzelne aus Farb- und Feuchtwerken bestehende Einheiten seitlich aus den Druckwerken ausziehbar sind, sondern die gesamten einander gegenüberliegenden Druckwerke seitlich versetzt angeordnet werden können, ist es möglich, dass insbesondere Wartungsarbeiten an im wesentlichen allen Teilen der Druckwerke durchgeführt werden können, ohne dass im wesentlichen weitere Maßnahmen zur Öffnung der Druckwerke erforderlich sind.Since not only individual consisting of inking and dampening units are laterally from the printing units extendable, but the entire opposing printing units can be arranged laterally offset, it is possible that in particular maintenance work on substantially all parts of the printing units can be performed without essentially further measures to open the printing units are required.

Grundsätzlich ist es ausreichend, wenn zur Trennung der einander gegenüberliegenden Druckwerke diese relativ zueinander in achsparalleler Richtung der Rotationsachsen der Zylinder seitlich versetzt anordenbar sind. Besonders vorteilhaft ist es jedoch, wenn die Druckwerke zusätzlich relativ zueinander zumindest geringfügig abstandsveränderbar angeordnet werden können. Beim Auseinanderfahren eines aus zwei gegenüberliegenden Druckwerken bestehenden Druckwerkes kann dann beispielsweise zunächst das eine Druckwerk in Richtung quer zu den Rotationsachsen der Zylinder verfahren werden, bis zumindest ein geringfügiger Abstand zwischen den Druckwerken entstanden ist. Durch diese Bewegung quer zur Richtung der Rotationsachsen der Zylinder können die Druckwerke zunächst außer Eingriff gebracht werden. Anschließend kann ein Druckwerk in achsparalleler Richtung der Rotationsachsen der Zylinder verschoben werden, um die innenliegenden Teile der Druckwerke zugänglich zu machen.In principle, it is sufficient if, in order to separate the opposing printing units, these are arranged laterally offset relative to one another in the axis-parallel direction of the axes of rotation of the cylinders. It is particularly advantageous, however, if the printing units can additionally be arranged at least slightly different distances relative to each other. When moving apart one of two opposing printing units existing printing unit then, for example, first a printing unit can be moved in the direction transverse to the axes of rotation of the cylinder until at least a slight distance between the printing units has arisen. By this movement transversely to the direction of the axes of rotation of the cylinder, the printing units can first be disengaged. Subsequently, a printing unit in the axis-parallel direction of the axes of rotation of the cylinder can be moved to make the inner parts of the printing units accessible.

Vorteilhafte Ausführungsformen der Erfindung ergeben sich aus der Kombination von erfindungsgemäßen Merkmalen mit Merkmalen, die bereits aus dem Stand der Technik bekannt sind. Insbesondere aus der EP 07 49 369 B1 und der DE 198 33 468 A1 sind Merkmale bekannt, deren Kombination zu einer erfindungsgemäßen Anordnung von Druckwerken besonders vorteilhaft ist.Advantageous embodiments of the invention result from the combination of features according to the invention with features which are already known from the prior art. In particular from EP 07 49 369 B1 and DE 198 33 468 A1 features are known, the combination of which is particularly advantageous for an inventive arrangement of printing units.

In the present embodiment, the pins of the transfer cylinder 08; 09; 11; 12 pivotally mounted in eccentric bushings or three-ring bearing technology, so that the transfer cylinder 08; 09; 11; 12 to the associated impression cylinder 13; 14 are turned on and off. It is also possible, the Gege-, fruckz%, linder 13; 14 to the associated Überkragungszylinder 08; 09; 11; 12, z. B. by means of eccentric bushings, three-ring bearings or linear guide, hiring.

Im vorliegenden Ausführungsbeispiel ist jeder Zylinder 03; 04; 06; 07; 08; 09; 11; 12; 13; 14 mit einem eigenen drehzahlgeregelten und/oder lagegeregelten Antriebsmotor versehen. Es ist aber auch möglich, jedem Paar Form- und Übertragungszylinder 03, 08; 04, 09; 06, 11; 07, 12 einen Antriebsmotor zuzuordnen und dieses Paar formschlüssig zu koppeln. Dabei weist auch der Gegendruckzylinder 13; 14 einen eigenen Antriebsmotor auf oder ist an eines der Paare der Form- und Übertragungszylinder 03, 08; 04, 09; 06, 11; 07, 12 koppelbar. Auch ist es möglich, jedes Druckwerk 01; 02 nur einen Antriebsmotor zuzuordnen und das zu übertragende Antriebsmoment beispielsweise mit einer Stehwelle zu übertragen. Unabhängig von der Art des Antriebs können zwischen einem oder mehreren Zylindern und dem jeweils zugeordneten Antrieb jeweils eine Kupplung angeordnet sein, so dass einzelne Zylinder bzw. Zylindergruppen separat zuschaltbar sind. In jedem Fall sind die Antriebsmotoren unabhängig von der Lage und dem Aufstellungsort der Druckwerke 01; 02 je einem Seitengestell 16; 17 fest zugeordnet, so dass bei dem um 180° um eine Vertikale geschwenkt aufgestellten Druckwerk 02 die Antriebsmotoren auf der gegenüberliegenden Seite der Druckmaschine angeordnet sind. Den Formzylindern 03; 04; 06; 07 ist jeweils ein Farbwerk 18; 19; 21; 22 und ein Feuchtwerk 23; 24; 26; 27 zugeordnet. Bei der dargestellten Ausführungsform ist das Druckwerk 01, z. B. als V-Druckwerk 01 und das Druckwerk 02, z. B. als W-Druckwerk 02, ausgebildet. Die Druckwerke 01; 02 können jeweils unabhängig voneinander als sich gegenüberliegende Fünfzylinder-Druckwerke betrieben werden, d. h. zwei gegenüberliegende Druckwerke bilden in einer ersten Betriebsart funktional eine Zehnzylinder-Satellitendruckwerk. Während dieses ersten Betriebszustandes wirken die Übertragungszylinder 08; 09; 11; 12 mit dem jeweiligen Gegendruckzylinder 13; 14 des V-Druckwerks 01 und W-Druckwerks 02 zusammen. In einem zweiten Betriebszustand wirken zwei Fünfzylinder-Druckwerke funktional als Neunzylinder-Satellitendruckwerk. Dieser Betriebszustand ist in Fig. 1 dargestellt. Dazu sind die Übertragungszylinder 08; 09; 11; 12 des V-Druckwerks 01 und des W-Druckwerks 02 an dem Gegendruckzylinder 13 des V-Druckwerks 01 an- und abstellbar. Der Gegendruckzylinder 14 des W-Druckwerks 02 ist in diesem Betriebszustand nicht am Druckprozess beteiligt.In the present embodiment, each cylinder 03; 04; 06; 07; 08; 09; 11; 12; 13; 14 provided with its own speed-controlled and / or position-controlled drive motor. But it is also possible for each pair of forming and transfer cylinders 03, 08; 04, 09; 06, 11; 07, 12 assign a drive motor and to couple this pair form fit. In this case, the impression cylinder 13; 14 has its own drive motor or is connected to one of the pairs of forming and transfer cylinders 03, 08; 04, 09; 06, 11; 07, 12 can be coupled. It is also possible, each printing unit 01; 02 assign only one drive motor and to transmit the transmitted torque, for example, with a standing wave. Regardless of the type of drive, in each case one clutch can be arranged between one or more cylinders and the respective associated drive, so that individual cylinders or cylinder groups can be connected separately. In any case, the drive motors are independent of the location and the site of the printing units 01; 02 each a side frame 16; 17 permanently assigned, so that in the 180 ° about a vertical set up printing unit 02, the drive motors are arranged on the opposite side of the printing press. The form cylinders 03; 04; 06; 07 is in each case an inking unit 18; 19; 21; 22 and a dampening unit 23; 24; 26; 27 assigned. In the illustrated embodiment, the printing unit 01, z. B. as V-printing unit 01 and the printing unit 02, z. B. as W printing unit 02, formed. The printing units 01; 02 can each be operated independently of each other as opposed five-cylinder printing units, ie two Opposite printing units functionally form a ten-cylinder satellite printing unit in a first operating mode. During this first operating state, the transfer cylinders 08; 09; 11; 12 with the respective impression cylinder 13; 14 of the V-printing unit 01 and W-printing unit 02 together. In a second operating state, two five-cylinder printing units function functionally as a nine-cylinder satellite printing unit. This operating state is shown in FIG. 1. For this purpose, the transfer cylinders 08; 09; 11; 12 of the V-printing unit 01 and the W-printing unit 02 on the impression cylinder 13 of the V-printing unit 01 on and off. The impression cylinder 14 of the W printing unit 02 is not involved in the printing process in this operating state.

Die Druckwerke 01; 02 sind in einer Tragvorrichtung befestigt, von der in Fig. 1 lediglich die Querträger 28; 29 schematisch dargestellt sind. Dabei ist das V-Druckwerk 01 ortsfest mit den Querträgern 28; 29 verbunden, wo hingegen das W-Druckwerk 02 verstellbar in der Tragvorrichtung gelagert ist. Insbesondere zur Bedienung und Wartung der Druckwerke 01; 02 durch das Bedienpersonal kann das aus den Druckwerken 01; 02 gebildete Druckwerk 01; 02 geöffnet werden. Die erforderlichen Stellbewegungen zur Öffnung des aus den Druckwerken 01; 02 gebildeten Druckwerk 01; 02 sind schematisch in den Fig. 2 bis 4 dargestellt.The printing units 01; 02 are mounted in a support device, of which in Fig. 1, only the cross member 28; 29 are shown schematically. In this case, the V-printing unit 01 is stationary with the cross members 28; 29, where, however, the W printing unit 02 is adjustably mounted in the support device. In particular for the operation and maintenance of the printing units 01; 02 by the operator can from the printing units 01; 02 formed printing unit 01; 02 are opened. The required positioning movements for opening the from the printing units 01; 02 formed printing unit 01; 02 are shown schematically in Figs. 2 to 4.

Die Druckwerke 01; 02 sind in den Fig. 2 bis 4 lediglich schematisch unter Hinweglassung der umgebenden Tragvorrichtung dargestellt. In Fig. 2 sind die Druckwerke 01; 02 im Betriebszustand, der dem Betriebszustand in Fig. 1 entspricht, in Ansicht von oben dargestellt. Das beweglich gelagerte Druckwerk 02 ist an den ortsfest gelagerten Druckwerke 01 verriegelt, so dass die Druckwerke 01; 02 zusammen ein ortsfestes Druckwerk 01; 02 bilden. Zum Öffnen des Druckwerkes 01; 02 werden die Druckwerke 01; 02, wie in Fig. 3 dargestellt, zunächst dadurch getrennt, dass das Druckwerk 02 in einer durch einen Bewegungspfeil 31 angedeuteten Stellbewegung in einer Richtung quer zu den Rotationsachsen der Zylinder 03; 04; 06; 07; 08; 09; 11; 12; 13; 14 verschoben wird. Dadurch entsteht ein Abstand zwischen den Druckwerken 01; 02, so dass die Druckwerke 01; 02 nicht mehr miteinander in Eingriff stehen. Anschließend wird das Druckwerk 02, wie in Fig. 4 dargestellt, in einer durch den Bewegungspfeil 32 angedeuteten Stellbewegung in eine Richtung achsparallel zu den Rotationsachsen der Zylinder 03; 04; 06; 07; 08; 09; 11; 12; 13; 14 zur Seite verschoben, so dass abhängig vom seitlichen Versatz zwischen den Druckwerken 01; 02 immer größere Bereiche des Inneren der Druckwerke 01; 02 für Bedienungs- und Wartungsarbeiten zugänglich werden. Das Druckwerk 02 kann dabei so weit nach außen, d. h. beim dargestellten Ausführungsbeispiel so weit nach vorne verschoben werden, dass die Druckwerke 01; 02 einander nicht mehr gegenüber liegen, so dass alle Bereiche des Inneren der Druckwerke 01; 02 von in den Bereichen 33; 34 angeordneten Arbeitsbühnen zugänglich sind. Zum Schließen des aus den Druckwerken 01; 02 gebildeten Druckwerken 01; 02 wird das Druckwerk 02 in umgekehrter Reihenfolge verschoben und zuletzt an das Druckwerk 01 verriegelt.The printing units 01; 02 are shown in FIGS. 2 to 4 only schematically with omission of the surrounding support device. In Fig. 2, the printing units 01; 02 in the operating state, which corresponds to the operating state in Fig. 1, shown in top view. The movably mounted printing unit 02 is locked to the stationary mounted printing units 01, so that the printing units 01; 02 together a stationary printing unit 01; 02 form. To open the printing unit 01; 02, the printing units 01; 02, as shown in Fig. 3, initially separated by the fact that the printing unit 02 in a direction indicated by a movement arrow 31 actuating movement in a direction transverse to the axes of rotation of the cylinder 03; 04; 06; 07; 08; 09; 11; 12; 13; 14 is moved. This creates a distance between the printing units 01; 02, so that the printing units 01; 02 are no longer engaged with each other. Subsequently, the Printing unit 02, as shown in Figure 4, in a direction indicated by the movement arrow 32 actuating movement in a direction axially parallel to the axes of rotation of the cylinder 03; 04; 06; 07; 08; 09; 11; 12; 13; 14 shifted to the side, so that depending on the lateral offset between the printing units 01; 02 ever larger areas of the interior of the printing units 01; 02 are accessible for operation and maintenance. The printing unit 02 can be so far outward, ie so far moved forward in the illustrated embodiment that the printing units 01; 02 are no longer facing each other, so that all areas of the interior of the printing units 01; 02 of in the areas 33; 34 arranged working platforms are accessible. To close the from the printing units 01; 02 formed printing units 01; 02, the printing unit 02 is moved in the reverse order and last locked to the printing unit 01.

Fig. 5 zeigt eine zweite Ausführungsform einer Anordnung von Druckwerken 48; 49; 51; 52; 58; 59; 61; 62. Der obere Träger 40; 41 sowie der untere Träger 42; 44 einer Mehrfarbenrollen-Rotationsdruckmaschine nehmen mehrere übereinander angeordnete Druckwerke 48; 49; 51; 52; 58; 59; 61; 62 in einem linken Rahmenteil 55, das auf den Seitengestellen 46; 47 gebildet ist, trägerfest auf. Die im linken Rahmenteil 55 angeordneten Druckwerke 48; 49; 51; 52 sind ortsfest gelagert und werden nachfolgend als linkes Druckwerk 48; 49; 51; 52 bezeichnet. Zwischen den Trägern 40; 41; 42; 44 ist weiterhin ein auf Rollen 53; 54 verschiebbarer rechter Rahmenteil 65 angeordnet, der aus den Seitengestellen 56; 57 gebildet ist. In den Seitengestellen 56; 57 sind die rechten Druckwerke 58; 59; 61; 62 den linken Druckwerken 48; 49; 51; 52 gegenüberliegend angeordnet.Fig. 5 shows a second embodiment of an arrangement of printing units 48; 49; 51; 52; 58; 59; 61; 62. The upper carrier 40; 41 and the lower carrier 42; 44 of a multi-color roll rotary printing machine take a plurality of superimposed printing units 48; 49; 51; 52; 58; 59; 61; 62 in a left frame part 55, which on the side frames 46; 47, carrier-resistant. The arranged in the left frame part 55 printing units 48; 49; 51; 52 are stored stationary and are hereinafter referred to as left printing unit 48; 49; 51; 52 denotes. Between the carriers 40; 41; 42; 44 is further a on rollers 53; 54 slidable right frame member 65 arranged from the side frames 56; 57 is formed. In the side frames 56; 57 are the right printing units 58; 59; 61; 62 the left printing units 48; 49; 51; 52 arranged opposite one another.

Die Konstruktion der einzelnen Druckwerke 48; 49; 51; 52 und 58; 59; 61; 62 und der daraus gebildeten Druckwerke entspricht der in der EP 07 49 369 B1 beschriebenen Konstruktion in den wesentlichen Merkmalen. Jedes Druckwerk 48; 49; 51; 52 und 58; 59; 61; 62 besteht jeweils aus einem Übertragungszylinder 63, beispielsweise einem Gummituchzylinder, der mit einem Formzylinder 64, beispielsweise einem Plattenzylinder zusammen wirkt. Der Formzylinder 64 erhält Feuchtmittel über ein Feuchtwerk 66 und Farbe über ein Farbwerk 67. Das Farbwerk 67 kann z. B. aus einer Farbwanne mit einer Farbwalze bestehen, wobei die Farbwalze ihre Druckfarbe mittels Farbauftragswalzen an die Formzylinder 64 überträgt. Statt zweier gleich großer Farbauftragswalzen kann auch nur eine kleinere oder größere Farbauftragswalze eingesetzt werden. Anstelle einer Farbwanne sowie einer Farbwalze kann z. B. auch eine Kammerrakel in Verbindung mit einer Rasterwalze (Aniloxwalze) verwendet werden. Es kann jedoch auch ein konventionelles Farbwerk eingesetzt werden.The construction of the individual printing units 48; 49; 51; 52 and 58; 59; 61; 62 and the printing units formed therefrom corresponds to the construction described in EP 07 49 369 B1 in the essential features. Each printing unit 48; 49; 51; 52 and 58; 59; 61; Each 62 consists of a transfer cylinder 63, such as a blanket cylinder, with a forme cylinder 64, such as a plate cylinder works together. The forme cylinder 64 receives dampening solution via a dampening unit 66 and color via an inking unit 67. The inking unit 67 may, for. Example, consist of a paint tray with an ink roller, wherein the ink roller transmits its ink by means of inking rollers to the forme cylinder 64. Instead of two equally sized inking rollers and only a smaller or larger inking roller can be used. Instead of a paint tray and a paint roller z. As well as a chamber doctor blade in conjunction with an anilox roller (anilox roller) can be used. However, it is also possible to use a conventional inking unit.

Jedes Feuchtwerk 66 kann als Sprühfeuchtwerk ausgebildet sein, welches aus einer bekannten Sprüheinrichtung, z. B. einer Leiste mit Sprühdüsen besteht, welche ihre Sprühstrahlen auf eine Feuchtmittelauftragswalze richten. Diese Feuchtmittelauftragswalze steht mit dem Formzylinder 64 in Verbindung.Each dampening unit 66 may be formed as Sprühfeuchtwerk, which consists of a known spray, z. B. a bar with spray nozzles, which direct their spray jets on a dampening form roller. This dampening form roller is in communication with the forme cylinder 64.

Die zwischen den Trägem 40; 42 stationär übereinander angeordneten Druckwerken 48; 49; 51; 52 sowie die zwischen den Trägem 41; 44 im verschiebbaren Rahmenteil 65 übereinander angeordneten Druckwerken 58; 59; 61; 62 sind jeweils mit ihrem Übertragungszylinder 63 gegeneinander gerichtet angeordnet, so dass jeweils eine Bahn 68 oder 69 beidseitig bedruckt werden kann. Im Ergebnis bilden die Druckwerke 48 mit 58; 49 mit 59; 51 mit 61 und 52 mit 62 jeweils eine Brückendruckeinheit bzw. eine Druckeinheit in Brückenbauweise.The between the carriers 40; 42 stationary superposed printing units 48; 49; 51; 52 and between the carriers 41; 44 in the sliding frame part 65 superposed printing units 58; 59; 61; 62 are each directed with their transfer cylinder 63 against each other, so that in each case a web 68 or 69 can be printed on both sides. As a result, the printing units 48 form 58; 49 with 59; 51 with 61 and 52 with 62 each have a bridge pressure unit or a pressure unit in bridge construction.

Das rechte Druckwerk 58; 59; 61; 62 ist dabei im verschiebbaren Rahmenteil 65 derart angeordnet, dass es relativ zu den linken Druckwerken 48; 49; 51; 52 horizontal in achsparalleler Richtung der Rotationsachsen der Zylinder 63; 64 verschoben werden können. Zur Verdeutlichung dieser Funktion sind der linke und der rechte Rahmenteil 55; 65 in Fig. 6 und 7 in Ansicht von oben dargestellt. Die Darstellung in Fig. 6 und 7 ist rein schematisch unter Weglassung aller für das Verständnis der Funktion nicht erforderlichen Einzelheiten. In Fig. 6 sind der linke und der rechte Rahmenteil 55; 65 im Betriebszustand dargestellt, in dem sie miteinander verriegelt sind. Nach der Entriegelung kann der linke Rahmenteil 65, wie durch einen Bewegungspfeil 71 angedeutet, in achsparalleler Richtung zu den Rotationsachsen der Zylinder 63; 64 zur Seite verschoben werden. Dazu sind zwischen den Trägern 40; 41; 42; 44 Laufschienen 72; 73 vorgesehen, in denen die Rollen 53; 54 gelagert sind.The right printing unit 58; 59; 61; 62 is arranged in the displaceable frame part 65 such that it is relative to the left printing units 48; 49; 51; 52 horizontally in the axis-parallel direction of the axes of rotation of the cylinder 63; 64 can be moved. To illustrate this function, the left and the right frame part 55; 65 in Fig. 6 and 7 shown in top view. The illustration in Fig. 6 and 7 is purely schematic, omitting all details not required for understanding the function. In Fig. 6, the left and right frame members 55; 65 shown in the operating state in which they are locked together. After unlocking, the left Frame part 65, as indicated by a movement arrow 71, in the axis-parallel direction to the axes of rotation of the cylinder 63; 64 are moved to the side. These are between the carriers 40; 41; 42; 44 rails 72; 73 provided, in which the rollers 53; 54 are stored.

Zusätzlich können die rechten Druckwerke 58; 59; 61; 62 relativ zu den linken Druckwerken 48; 49; 51; 52 in Richtung der Rotationsachsen der Zylinder 63; 64 verschoben werden.In addition, the right printing units 58; 59; 61; 62 relative to the left printing units 48; 49; 51; 52 in the direction of the axes of rotation of the cylinder 63; 64 are moved.

Wie in Fig. 7 dargestellt, kann der rechte Rahmenteil 65 so weit seitlich nach außen, d. h. in der dargestellten Ausführungsform so weit nach rechts, verschoben werden, bis die linken und rechten Druckwerke 48; 49; 51; 52 und 58; 59; 61; 62 vollständig voneinander getrennt sind und dadurch für Bedienungs- bzw. Wartungsarbeiten von in den Bereichen 74 bzw. 76 angeordneten Arbeitsbühnen gut für das Bedienpersonal zugänglich sind. Der verschiebbare rechte Rahmenteil 65 kann beispielsweise mittels zweier doppelt wirkender Arbeitszylinder, z. B. Hydraulikzylinder, betätigt werden. Es sind jedoch selbstverständlich auch andere Antriebsarten, beispielsweise mit Elektromotoren, denkbar. Zur Führung des rechten Rahmenteils 65 können beispielsweise aus der EP 07 49 369 B1 bekannte Führungsleisten Verwendung finden. Zum Erzielen einer hohen Passgenauigkeit in der Betriebsstellung des verschiebbaren Rahmenteils 65 können mehrere über die Schließkante hinausragende Zapfen am Rahmenteil 65 vorgesehen sein, die in entsprechend angeordneten Sacklochbohrungen am ortsfesten linken Rahmenteil 55 zum Eingriff bringbar sind.As shown in Fig. 7, the right frame member 65 so far laterally outward, d. H. in the illustrated embodiment so far to the right, be moved until the left and right printing units 48; 49; 51; 52 and 58; 59; 61; 62 are completely separated from each other and thus are well accessible to the operating personnel for operation or maintenance of arranged in the areas 74 and 76 work platforms. The displaceable right frame member 65 may, for example, by means of two double-acting cylinder, z. B. hydraulic cylinders are operated. However, it is of course also other types of drives, for example with electric motors conceivable. For guiding the right-hand frame part 65, known guide rails can be used, for example, from EP 07 49 369 B1. To achieve a high accuracy of fit in the operating position of the displaceable frame part 65, a plurality of pins projecting beyond the closing edge can be provided on the frame part 65, which can be brought into engagement in correspondingly arranged blind holes on the stationary left frame part 55.

In der Arbeitsstellung (Fig. 5) ist das verschiebbare Rahmenteil 65 gegen ein unbeabsichtigtes Verschieben mittels einer mechanisch wirkenden Sperrvorrichtung 77 gesichert. Die Sperrvorrichtung 77 besteht aus einer rahmenfest gelagerten Gewindebuchse, welche beim Schließen des rechten Rahmenteils 65 mit einer trägerfest gelagerten Gewindespindel eine formschlüssige Verbindung bildet. Dabei wird die Gewindespindel mittels einer motorbetriebenen Gewindehülse in Richtung des linken Rahmenteils 55 bewegt.In the working position (FIG. 5), the displaceable frame part 65 is secured against unintentional displacement by means of a mechanically acting locking device 77. The locking device 77 consists of a frame-mounted threaded bushing which forms a positive connection when closing the right frame part 65 with a carrier-mounted threaded spindle. In this case, the threaded spindle by means of a motor-driven threaded sleeve in the direction of the left Frame part 55 moves.

Es ist möglich, während des Stillstandes die auf den Formzylindern 64 des linken und rechten Druckwerkes 48; 49; 51; 52 bzw. 58; 59; 61; 62 befindlichen Druckplatten durch das Bedienpersonal manuell zu wechseln. Dazu müssen die Rahmenteile 55; 65 so weit auseinander gefahren werden, bis die entsprechenden Formzylinder 64 in ausreichendem Maß zugänglich sind. Alternativ dazu ist es möglich, die auf den Formzylindern 64 befindlichen Druckplatten mittels einer jedem Druckwerk 48; 49; 51; 52 bzw. 58; 59; 61; 62 zugeordneten Druckplattenwechselvorrichtung 78 zu wechseln. Die Druckplattenwechselvorrichtung 78 kann beispielsweise wie die in der EP 07 49 369 B1 beschriebene Druckplattenwechselvorrichtung ausgebildet sein.It is possible during standstill on the form cylinders 64 of the left and right printing unit 48; 49; 51; 52 and 58, respectively; 59; 61; 62 are manually changed by the operating personnel. For this purpose, the frame parts 55; 65 are moved so far apart until the corresponding form cylinder 64 are sufficiently accessible. Alternatively, it is possible, the pressure plates located on the form of cylinders 64 by means of each printing unit 48; 49; 51; 52 and 58, respectively; 59; 61; 62 associated printing plate changing device 78 to change. The printing plate changing device 78 may be formed, for example, like the printing plate changing device described in EP 07 49 369 B1.

Der Antrieb der einzelnen Druckwerke 48; 49; 51; 52 bzw. 58; 59; 61; 62 kann über eine Stehwelle oder über einzelne den einzelnen Zylinder zugeordnete Antriebsmotoren erfolgen. Ein geeignetes Antriebskonzept ist beispielsweise in der EP 07 49 369 B1 beschrieben.The drive of the individual printing units 48; 49; 51; 52 and 58, respectively; 59; 61; 62 can be done via a standing wave or via individual individual cylinders associated drive motors. A suitable drive concept is described for example in EP 07 49 369 B1.
