Definitions

the invention relates to a method applicable to printing machines for influencing the Transfer rate of media such as paint, water or paint.
anilox roller which interacts with a chambered doctor blade and at least one transfer roller which interacts with the anilox roller and a forme cylinder (DE 4344084 C1).
the anilox roller is connected to the drive wheel train of the printing press and rotates with the downstream roller at the same peripheral speed.
the object of the invention is to provide a method for effectively influencing the Transfer rate of that provided by a chambered doctor blade system - anilox roller / chambered doctor blade Medium without much effort.
the amount of the medium to be transferred (transfer rate v 0 ) is determined by the circumferential speed difference v diff of an anilox roller or a transfer roller in relation to a downstream roller.
the transmission diagram for the medium is shown in Fig. 2.
the diagram shows the transmission rate in relation to the percentage circumferential speed difference v diff , wherein a percentage circumferential speed difference one means the same circumferential speed between the anilox roller and the downstream roller.
the transfer rate v 0 between anilox roller and downstream roller, ie applicator roller, forme cylinder or transfer roller is changed by only a slight change in the peripheral speed of the anilox roller or transfer roller to the downstream roller and thus creating a minimal peripheral speed difference v diff .
the range of percentage change in peripheral speed between anilox roller or transfer roller and downstream roller ranges from 0.970 to 1.015.
An effective change in the transmission rate and thus, for example, in the color transmission of the optical density on the printed sheet is only possible in this minimal range.
the change in peripheral speed can take place in a positive or negative direction, ie as a reduction in peripheral speed or as an increase in peripheral speed. This means that several operating options are possible.
the transmission rate v 0 is reduced from the first operating point B 1 - circumferential speed difference one, ie synchronism - by creating a circumferential speed difference.
This variant can also be included in a control loop.
the circumferential speed difference v diff is increased and, in order to avoid an oversupply of color, the transmission rate v 0 is reduced.
the printing press is normally operated at the second operating point B 2 , which lies on the ascending or descending branch of the curve (FIG. 2).
Fig. 1 the roller diagrams of a short application unit (anilox technique) of a sheet-fed printing machine is shown.
the method according to the invention can be applied to this short application.
the roller diagram shows a printing cylinder 1 with gripper systems 2, an offset cylinder 3 and a forme cylinder 4.
the anilox roller 5 with a chambered doctor blade 6 is indirectly assigned to the forme cylinder 4 via an application roller 7 for ink application.
the anilox roller 5 is assigned a variable-speed drive 8.
a transfer roller can be arranged between the application roller 7 and the anilox roller 5. In this case, either the anilox roller 5 or the transfer roller of the variable-speed drive 8 is assigned.
the variable-speed drive 8 is designed as a self-drive, for example as a motor.
the Drive can also by incorporating the drive gear of the anilox roller 5 or the transfer roller in the drive wheel train of the printing press and the interposition of a speed-controlling Conversion element between the drive gear and anilox roller 5 or transfer roller respectively.
a conversion element for the minimal circumferential speed difference to be realized brakes, clutches, etc. can even be used.
the anilox roller 5 can in the direction of rotation synchronous operation (by direction arrow in Fig. 1st indicated) work, d. H. the anilox roller and the downstream roller have at the point of contact same direction of rotation.
the anilox roller 5 works in reverse mode (by double arrow in FIG. 1 indicated); d. H. the anilox roller and the downstream roller have different points of contact Direction of rotation.
