Ein Farbwerk für Offsetdruckmaschinen, welches als Filmfarbwerk oder Heberfarbwerk umstellbar betrieben werden kann, ist aus der DE 2 703 424 B1 bekannt. Im Heberbetrieb wird die Farbheberwalze zwischen Farbkastenwalze und der zugeordneten Farbabnahmewalze des Walzenzuges verschwenkt. Bei Umstellung auf Filmbetrieb wird die Farbabnahmewalze mit der Farbkastenwalze gekoppelt und die Farbheberwalze dient als Reiterwalze. Über eine Exzenterlagerung ist die Farbabnahmewalze in beide Stellungen überführbar. Nachteilig bei der Ausführung nach DE 3 606 006 ist es, daß die Farbkastenwalze nicht mit dem restlichen Walzenzug gereinigt werden kann und somit vom Bediener manuell gereinigt werden muß.An inking unit for offset printing machines, which as a film inking unit or lifter inking unit can be operated, is from the DE 2 703 424 B1 known. The ink lifter roller is in lift operation between the ink fountain roller and the assigned ink removal roller Single drum roller pivoted. When switching to film operation, the Ink take-up roller coupled to the ink fountain roller and the ink lifter roller serves as a rider roller. About an eccentric bearing Ink pick-up roller can be transferred to both positions. A disadvantage of the Execution according to DE 3 606 006 is that the ink fountain roller is not compatible with the rest of the single drum roller can be cleaned and therefore manually by the operator must be cleaned.

Durch Zuschalten einer zusätzlichen Walze ist im Reinigungsbetrieb die Farbkastenwalze über diese Walze mit der Farbheberwalze in Kontakt. Die Farbheberwalze ist darüber hinaus mit der Farbabnahmewalze in Kontakt, so daß alle genannten Walzen einen Walzenzug bilden.A device for cleaning an inking unit is known from US Pat. No. 4,643,092 an ink fountain roller, an ink lifter roller and an ink take-off roller known. By switching on an additional roller in the cleaning operation Ink fountain roller in contact with the ink lifter roller via this roller. The Ink lifter roller is also in contact with the ink take-off roller, so that everyone called rollers form a single drum roller.

Schließlich ist aus der JP -A- 57120443 (Patent Abstracts of Japan, Bnd. 6, Nr. 213 (M-167) ), eine weitere Einrichtung zum Reinigen eines Farbwerkes mit einer Farbzuführwalze, einer Farbheberwalze sowie einer Farbabnahmewalze bekannt. Durch Abschwenken eines Stützhebels um eine Stützwelle wird ein weiterer, die Farbheberwalze tragender Hebel federbelastet bewegt, derart, daß die Farbheberwalze mit der Farbzuführwalze und der Farbabnahmewalze in Kontakt ist.Finally, JP-A-57120443 (Patent Abstracts of Japan, Vol. 6, No. 213 (M-167)), another device for cleaning an inking unit with a Ink feed roller, an inking roller and an ink take-off roller are known. By pivoting a support lever around a support shaft, another, the Ink lifter roller carrying lever moves spring-loaded, such that the Ink lifter roller is in contact with the ink feed roller and the ink take-off roller.

Aufgabe der Erfindung ist es eine Lösung zu entwickeln, die eine gleichzeitige Reinigung von Farbkastenwalze und dem nachgeordneten Walzenzug gestattet.The object of the invention is to develop a solution that a simultaneous Cleaning of ink fountain roller and the downstream single drum roller permitted.

Gelöst wird das dadurch, daß die Farbheberwalze mit der Farbkastenwalze und der Farbabnahmewalze gekoppelt wird. Dadurch werden die Farbkastenwalze und die Farbheberwalze mit dem weiteren Farbwerkswalzenzug gereinigt. Dies befreit den Bediener von der manuellen Reinigungstätigkeit, verringert die Rüstzeit bei Farbwechsel und automatisiert somit das Reinigen des gesamten Farbwerkes.This is solved in that the inking roller with the ink fountain roller and Ink take-up roller is coupled. As a result, the ink fountain roller and the Ink lifter roller cleaned with the further inking unit roller. This frees the Operator from manual cleaning activity, reduces the set-up time Color change and thus automates the cleaning of the entire inking unit.

Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden.The invention will be explained in more detail using an exemplary embodiment.

Dabei zeigt:

eine schematische Darstellung der angetriebenen Farbheberwalzen mit ihren benachbarten Walzen.
It shows:
Fig. 1
a schematic representation of the driven inking rollers with their adjacent rollers.

In einem Druckwerk einer Offsetrotationsdruckmaschine ist ein Heberfarbwerk angeordnet, von dem eine Farbkastenwalze 1 und eine Farbabnahmewalze 3 dargestellt sind. Der Farbabnahmewalze 3 ist ein Walzenzug nachgeordnet, dem mindestens eine Zuführeinrichtung für die Reinigungsflüssigkeit sowie eine Rakelwanne als Aufnahmeeinrichtung für das Farb-/Reinigungsflüssigkeitsgemisch zugeordnet ist (nicht gezeigt). Zwischen Farbkastenwalze 1 und Farbabnahmewalze 3 ist eine Farbheberwalze 2 intermittierend angeordnet. Die Farbheberwalze 2 ist stirnseitig drehbar an je einem Hebel 7 angeordnet. Der Hebel 7 ist mit einer Exzenterlagerung 4 drehbar fixiert und tragt am freien Ende eine Kurvenrolle 6. Der Kurvenrolle 6 ist eine Steuereinrichtung 5, z.B. als Kurvenscheibe, zugeordnet. Die Exzenterlagerung 4 ist über eine angelenkte Koppel 9 mit einem Arbeitszylinder 8 verbunden.In a printing unit of an offset rotary printing machine there is a lifter inking unit arranged, of which an ink fountain roller 1 and an ink take-off roller 3rd are shown. The ink take-off roller 3 is arranged downstream of a single drum roller at least one feed device for the cleaning liquid and one Doctor tray as receiving device for the ink / cleaning liquid mixture assigned (not shown). Between ink fountain roller 1 and ink take-off roller 3, an ink fountain roller 2 is arranged intermittently. The inking roller 2 is rotatably arranged on each end of a lever 7. Of the Lever 7 is rotatably fixed with an eccentric bearing 4 and carries at the free end a cam roller 6. The cam roller 6 is one Control device 5, e.g. assigned as a cam. The Eccentric bearing 4 is connected via an articulated coupling 9 Working cylinder 8 connected.

Die Wirkungsweise ist wie folgt: Nach Beendigung eines Druckauftrages, nach Schichtende oder bei einem ungünstigen Farb-/Feuchtmittelverhältnis ist es notwendig das Farbwerk zu reinigen. Dabei wird die Farbkastenwalze 1 von ihrem separaten Antrieb entkoppelt. Die Farbheberwalze 2 wird an ihrem Umfang in ständigen Kontakt mit der Farbkastenwalze 1 und der Farbabnahmewalze 3 gebracht (Reinigungsposition). Der Arbeitszylinder 8 wird dazu von einem Leitstand aus betätigt und bewegt über die Koppel 9 und die Exzenterlagerung 4 den Hebel 7, so daß die Farbheberwalze 2 in Reinigungsposition verbracht wird. Die intermittierende Bewegung der Farbheberwalze 2 ist dabei ausgesetzt, indem die Kurvenrolle 6 von der Steuereinrichtung 5 getrennt wird (siehe gestrichelte Darstellung). Die Farbkastenwalze 1 und Farbheberwalze 2 werden mittels Friktion über den nachgeordneten Walzenzug angetrieben. Die Zuführeinrichtung für die Reinigungsflüssigkeit wird aktiviert und das Farb-/Reinigungsflüssigkeitsgemisch wird von einer stromabwärts angeordneten Aufnahmeeinrichtung, z.B. einer Rakelwanne, von der betreffenden Farbwerkswalze abgerakelt.The mode of operation is as follows: after a print job has ended, after the end of the shift or with an unfavorable ink / dampening solution ratio it is necessary to clean the inking unit. The ink fountain roller 1 is driven by its separate drive decoupled. The inking roller 2 is in constant at its circumference Contact with the ink fountain roller 1 and the ink removal roller 3 brought (cleaning position). The working cylinder 8 is from actuated from a control station and moved over the coupling 9 and Eccentric 4 the lever 7 so that the inking roller 2 in Cleaning position is spent. The intermittent movement the inking roller 2 is exposed by the cam roller 6 is separated from the control device 5 (see dashed lines Presentation). The ink fountain roller 1 and ink fountain roller 2 are driven by friction on the downstream single drum roller. The Feeding device for the cleaning liquid is activated and the paint / cleaning fluid mixture is from a downstream arranged receiving device, e.g. a squeegee tray from which relevant inking unit roller doctored.

In einer weiteren Ausbildung bleibt die Farbkastenwalze 1 mit ihrem Antrieb gekoppelt, indem dieser mit dem Antrieb für die Farbabnahmewalze 3 und dem nachgeordneten Farbwalzenzug synchron in der Reinigungsposition mit gleicher Umfangsgeschwindigkeit betrieben wird. In Weiterbildung ist die Farbkastenwalze 1 auch mit zur Farbabnahmewalze 3 unterschiedlicher Umfangsgeschwindigkeit in der Reinigungsposition angetrieben. Der dabei auftretende Schlupf erhöht in Folge des Wischeffekts die Reinigungswirkung auf der Walzenoberfläche. In a further training, the ink fountain roller 1 remains with her Drive coupled by this with the drive for the ink roller 3 and the downstream inking roller synchronously in the Cleaning position operated at the same peripheral speed becomes. In a further development, the ink fountain roller 1 is also used for Ink take-up roller 3 different peripheral speed in the Cleaning position driven. The slip that occurs increases the cleaning effect on the Roller surface.
