Definitions
- the invention relates to an inking unit of a printing press.
- DE 195 23 378 A1 is a sheet-fed offset rotary printing press 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 each 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 and each printing surface of the forme cylinder is its own short inking unit, consisting of inking roller, anilox roller and ink fountain, assigned.
- the inking rollers are alternately on and off the forme cylinder adjustable, only inking the assigned printing area.
- the object of the invention is to provide an inking unit, the rollers for avoiding of effects caused by changes in position from the theoretical target position the color transfer can be carried out precisely.
- FIG. 1 shows the basic diagram of an inking unit of a printing press.
- a printing form cylinder 2 is rotatably mounted in the machine frame 1.
- An anilox roller 5 is also rotatably mounted in the machine frame 1 via bearing bushes 3 and first play-free bearings 4.
- On the legs 8 of the anilox roller 5 6 timing levers 7 are mounted in second play-free bearings.
- the ink fountain 9 which is operatively connected to the anilox roller 5 is arranged on the clock lever 7.
- the bearing point of the anilox roller 5 is split (Fig. 3).
- An inking roller 10 is mounted in the clock levers 7. In the operating position, the inking roller 10 is operatively connected to both the anilox roller 5 and the printing form cylinder 5.
- the active connections are not shown in FIG. 1; A stretched representation was chosen for better clarity.
- the inking roller 10 consists of a non-rotating thru axle 11 and a roller jacket 12 rotatably mounted on the non-rotating thru axle 11.
- An eccentric bearing 14 is mounted on both sides of the thru axle 11 in timing levers 7 via third play-free bearings 13.
- Elements for roller separation 15, ie elements for rotating the eccentric bearings, are arranged on the eccentric bearings 14. These elements for roller separation 15 are supported on the clock levers 7.
- the timing levers 7 in turn are supported on the side facing away from the bearing point via a cam roller 16 on a timing curve 17 arranged on the printing form cylinder 2 (FIG. 2).
- the clock levers 7 are arranged on both sides of the machine frame 1, the clocking elements 18.
- the formation of the inking roller 10 as a non-rotating thru axle 11 creates a synchronous cross-beam which ensures the necessary synchronism during roller separation and thus enables the use of play-free bearings. Since the ink fountain 9 is mounted on the clock levers 7, there is no difference in speed between the doctor blade of the ink fountain 9 and the anilox roller 5 during clocking.
- the inking unit since the bearing point of the anilox roller 5 is designed as a split bearing, can be completely removed or preassembled; the inking roller 10 is also removable after separation of thru axle 11 / timing lever 7. Due to the fact that the cam roller 16 lies in one plane with the clock lever bearing, there are no negative tilting moments. By mounting the clock lever 7 on the legs 8 of the anilox roller 5, the clocking - movement in a small swivel angle - a rotary movement is superimposed and thus ensures that sufficient lubrication of the bearings is ensured despite the small swivel angle.

Abstract
Description
Auf den Schenkeln 8 der Aniloxwalze 5 sind in zweiten spielfreien Lagern 6 Takthebel 7 gelagert. An dem Takthebel 7 ist der mit der Aniloxwalze 5 in Wirkverbindung stehende Farbkasten 9 angeordnet.
In den Takthebeln 7 ist eine Farbauftragwalze 10 gelagert. Die Farbauftragwalze 10 steht in Betriebsstellung sowohl mit der Aniloxwalze 5 als auch mit dem Druckformzylinder 5 in Wirkverbindung. In Fig. 1 sind die Wirkverbindungen nicht dargestellt; zur besseren Übersichtlichkeit wurde eine gestreckte Darstellung gewählt.
Die Farbauftragwalze 10 besteht aus einer nicht rotierenden Steckachse 11 und einem auf der nicht rotierenden Steckachse 11 drehbar gelagerten Walzenmantel 12. An der Steckachse 11 ist beidseitig je ein in Takthebeln 7 über dritte spielfreie Lager 13 gelagertes Exzenterlager 14 angeordnet. An den Exzenterlagern 14 sind Elemente zur Walzentrennung 15 d.h. Elemente zum Verdrehen der Exzenterlager angeordnet. Diese Elemente zur Walzentrennung 15 stützen sich an den Takthebeln 7 ab.
Die Takthebel 7 wiederum stützen sich auf der der Lagerstelle abgewandten Seite über eine Kurvenrolle 16 an einer am Druckformzylinder 2 angeordneten Taktkurve 17 ab (Fig. 2). Den Takthebeln 7 sind beidseitig sich am Maschinengestell 1 abstützende, die Taktung abstellende Elemente 18 angeordnet.
Durch die Ausbildung der Farbauftragwalze 10 als nicht rotierende Steckachse 11 entsteht eine Synchrontraverse, welche die notwendige Synchronität beim Walzentrennen gewährleistet und damit den Einsatz von spielfreien Lagern ermöglicht.
Da der Farbkasten 9 an den Takthebeln 7 gelagert ist, ergibt sich keine Differenzgeschwindigkeit zwischen dem Rakel des Farbkastens 9 und der Aniloxwalze 5 beim Takten.
Das Farbwerk ist, da die Lagerstelle der Aniloxwalze 5 als geteiltes Lager ausgebildet ist, komplett herausnehmbar bzw. vormontierbar; die Farbauftragwalze 10 ist nach Trennung Steckachse 11/Takthebel 7 ebenfalls herausnehmbar.
Bedingt dadurch, dass die Kurvenrolle 16 mit der Takthebellagerung in einer Ebene liegt treten keine sich negativ auswirkenden Kippmomente auf.
Durch die Lagerung der Takthebel 7 auf den Schenkeln 8 der Aniloxwalze 5 wird der Taktung ― Bewegung in einem kleinen Schwenkwinkel ― eine Drehbewegung überlagert und damit erreicht, dass trotz der kleinen Schwenkwinkel eine ausreichende Schmierung der Lager gewährleistet ist.
