Abstract

PROBLEM TO BE SOLVED: To realize a short ink introducing period by a method wherein a vibrating rollers is brought into simultaneous contact with both an ink fountain roller and an ink receiving roller during the ink introducing period. SOLUTION: In order to charge an ink arrangement at the start of a production or after the changing-over of works, a vibrating roller 3 is moved to a position, at which the vibrating roller 3 comes into simultaneous contact with both an ink fountain roller 1 and an ink accepting roller 4. At this time, a pivotally driving device 19 is stopped. At the same time, the separate driving device of the ink fountain roller 1 is properly controlled or the ink fountain roller 1 is cut off from its driving device. By being driven through the vibrating roller 3 and its following roller train by means of friction, the rotational frequency of the ink fountain roller 1 is matched with that of a machine. As a result, after the period of time shorter than that of the reciprocating motional operation of the vibrating roller 3, the ink film thickness necessary for the start of a printing is obtained in the ink arrangement. Thus, a short ink introducing period is realized.

[0003] The present invention is directed to another problem. When starting production or switching jobs, it is necessary to execute an ink introduction program (Farbeinlauf programm) on the printing press in order to obtain the filling level of the inking unit required for the start of printing. Due to the delay action of the ink transfer roller which comes into contact with the ink delivery roller or the ink receiving roller alternately at a predetermined cycle, the ink introduction program finally determines that all the film thicknesses in the inking unit are almost the same, and The operation time extends to several hundred machine rotations before printing can be started. This use of time is disadvantageous from an economic point of view, especially when switching jobs frequently.

According to the present invention, the filling time of the inking unit is significantly reduced by forming a closed roller row between the inking roller and the other rollers of the inking unit. This is because it is sufficient to achieve the desired defined start-of-print condition at a significantly lower machine speed. According to another proposal of the invention, the emptying of the inking unit, for example for an ink change, can also be considerably accelerated if the roller rows are closed by ink transfer rollers.

In the illustrated roller inking device, ink is transferred from an ink fountain 2 onto the surface of an inking roller 1 in the form of a defined ink film. The ink transfer roller 3 receives the ink from the ink discharging roller 1 and transfers the ink to the ink receiving roller 4. A plurality of intermediate rollers 5, a plurality of relay rollers (Uebertragungswalze) 7, 8 and an ink forming roller 9 are arranged behind the ink receiving roller 4. The inking roller 9 distributes the ink finely and supplies it to the plate cylinder 10 for depositing on the print image on the plate cylinder. The blanket cylinder 11 transfers the inlaid print image onto a printing surface (not shown).

For quick filling of the inking unit at the start of production or after a change of work, the ink transfer roller 3
The ink transfer roller 3 is moved to an illustrated position where it contacts the ink discharge roller 1 and the ink receiving roller 4 that can transfer ink. Furthermore, the swivel drive 19 is deactivated and the separate drive of the inking roller 1 is controlled appropriately or the inking roller 1
Is cut off from its drive and driven by friction through the ink transfer roller 3 and the subsequent roller train, whereby the speed of the ink delivery roller 1 is adapted to the machine speed. By means of the roller rows thus formed, from the inking roller 1 to the inking roller 9, a rapid ink filling of the inking unit is achieved, with the result that a significantly shorter time than the reciprocating operation of the ink transfer roller 3 is achieved. After that, the film thickness necessary for starting printing is obtained in the inking unit. For the subsequent printing start, the ink transfer roller 3 is moved to the dashed position by the adjustment movement of the swivel shaft 18 and reciprocated by the connection of the swivel drive 19, so that the ink transfer roller alternates between the ink delivery rollers 1 and It comes into contact with the ink receiving roller 4.
