Abstract
Description
Die Erfindung betrifft ein Farbwerk einer Druckmaschine.The invention relates to an inking unit of a printing press.
Durch die DE 195 23 378 A1 ist eine Bogenoffsetrotationsdruckmaschine für Mehrfarbendruck bestehend aus Formzylinder, Gummizylinder und einem mit einer Mehrzahl von gesteuerten Greifersystemen versehenen, zentralen Druckzylinder bekannt, wobei Formzylinder und Gummizylinder gleiche Durchmesser und jeweils mindestens zwei Druckflächen aufweisen sowie die Anzahl der Greifersysteme des Druckzylinders ungleich der Anzahl der Druckflächen des Formzylinders ist und dem Druckzylinder mindestens ein zweites aus Formzylinder und Gummizylinder bestehendes Zylinderpaar zugeordnet ist. Dabei weist jeder Formzylinder zwei um 180° versetzte Druckflächen auf und jeder Druckfläche der Formzylinder ist ein eigenes Kurzfarbwerk, bestehend aus Farbauftragwalze, Aniloxwalze und Farbkasten, zugeordnet. Die Farbauftragwalzen sind wechselnd von dem Formzylinder an- und abstellbar, nur die jeweils zugeordnete Druckfläche einfärbend, angeordnet.DE 195 23 378 A1 is a sheet-fed offset rotary printing machine for multi-color printing consisting of forme cylinder, rubber cylinder and one with a plurality of controlled Gripper systems provided, central pressure cylinder known, forme cylinder and blanket cylinders of the same diameter and at least two printing surfaces have and the number of gripper systems of the printing cylinder not equal to the number of Printing surfaces of the forme cylinder and the printing cylinder from at least a second Forme cylinder and blanket cylinder is assigned to an existing pair of cylinders. Each forme cylinder has two printing surfaces offset by 180 ° and each printing surface the forme cylinder is its own short inking unit, consisting of an inking roller and anilox roller and color box. The inking rollers are alternating from that The forme cylinder can be switched on and off, only coloring the assigned printing area.
Aufgabe der Erfindung ist die Schaffung eines Farbwerkes, dessen Farbauftragwalzen mit einer Taktkurve zu unterschiedlichen Takten taktweise an- und abstellbar sind.The object of the invention is to provide an inking unit, the inking rollers with a cycle curve can be switched on and off at different cycles.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des Patentanspruches gelöst.According to the invention the object is achieved by the features of the patent claim.
Nachfolgend wird die Erfindung an einem Ausführungsbeispiel näher beschrieben. Die Zeichnung zeigt den Taktantrieb der Farbauftragwalzen.The invention is described in more detail below using an exemplary embodiment. The drawing shows the clock drive of the inking rollers.
In der Zeichnung ist das Prinzipschema des Taktantriebes der Farbauftragwalzen eines
Farbwerkes einer Druckmaschine dargestellt.
Im Maschinengestell ist ein Druckformzylinder 1 mit zwei um 180° versetzten Drucksätteln
drehbar gelagert.
Am Druckformzylinder 1 ist eine Taktkurve 7 angeordnet.
Einer die erste mit dem Druckformzylinder 1 in Wirkverbindung stehende Farbauftragwalze 2
des ersten aus der ersten Farbauftragwalze 2, der ersten Rasterwalze 3 und des ersten
Farbkastens 4 bestehenden ersten Farbwerkes 5 ist in einem ersten Takthebel 6 angeordnet.
Der erste Takthebel 6 stützt sich auf der Taktkurve 7 ab. Die erste Farbauftragwalze 2
ist in der Zeichnung in der abgestellten Stellung dargestellt.
Eine mit dem Druckformzylinder 1 in Wirkverbindung stehende zweite Farbauftragwalze 8
des aus der zweiten Farbauftragwalze 8, der zweiten Rasterwalze 9 und des zweiten Farbkastens
10 bestehenden zweiten Farbwerkes 11 ist in einem zweiten Takthebel 12 angeordnet.
Der zweite Takthebel 12 stützt sich ebenfalls auf der Taktkurve 7 ab. Die zweite Farbauftragwalze
8 ist in der Zeichnung in der abgestellten Stellung dargestellt.
Die Takthebel 6; 12 laufen auf einer einzigen Taktkurve 7 ab und kreuzen sich.
Die an den Takthebeln 6; 12 angeordneten Kurvenrollen laufen damit einerseits 90° vorlaufend
und andererseits 90° nachlaufend zum jeweiligen Walzenspalt - Druckformzylinder/Farbauftragwalze
- auf der Taktkurve 7 ab.
Es ist die Verwendung der gleichen Taktkurve für die taktweise An- und Abstellung beider
Farbauftragwalzen möglich, obwohl diese über um 180° versetzte Drucksättel ausgehoben
werden.
Durch die gekreuzten Takthebel 6; 12 wird im Gegensatz zu einer nicht gekreuzten Ausführung
mit Formschluß, bei dem jede Abrollungleichförmigkeit der Kurvenrolle auf der Taktkurve
sich auf die Druckqualität auswirkt, eine kraftschlüssige Farbauftragwalzenanstellung an
den Druckformzylinder 1 möglich. The drawing shows the basic diagram of the clock drive of the inking rollers of an inking unit of a printing press.
A printing form cylinder 1 with two pressure saddles offset by 180 ° is rotatably mounted in the machine frame.
A clock curve 7 is arranged on the printing form cylinder 1.
One of the

The clock lever 6; 12 run on a single clock curve 7 and intersect.
The on the clock levers 6; 12 arranged cam rollers thus run on the one hand 90 ° leading and on the other hand 90 ° trailing to the respective nip - printing form cylinder / inking roller - on the cycle curve 7.
It is possible to use the same cycle curve for the intermittent on and off of both inking rollers, even though these are lifted using pressure saddles offset by 180 °.
