Embodiment Construction

[0036] exist figure 1 A tandem printer 100 is schematically shown in . Three printing units 110 a , 110 b and 110 c are shown here. The guidance and transport of the print medium 200 along the transport direction F takes place via a plurality of deflection cylinders and printing cylinders.

[0037] as from figure 1 As can be seen from the figure, this embodiment of the tandem printing press 100 is equipped with the monitoring system 10 according to the invention. The monitoring system has a control device 40 which is connected in signal communication to the sensor units 22 a , 22 b and 22 c of the sensor device 20 .

[0038] The sensor units 22a, 22b, and 22c are arranged in one printing unit 110a, 110b, and 110c, respectively. The individual sensor units 22 a , 22 b and 22 c are designed substantially identically and have a guide 24 for a translational movement transverse to the conveying direction F . In order to be able to generate the above-described movements of the ...

Abstract

The invention relates to a monitoring system (10) for the alignment of printing units (110a, 110b, 100c) of an inline printing press (100), having a sensor device (20) with at least one sensor unit (22a, 22b, 22c) for each printing unit (110a, 110b, 100c), in order to detect the position of a printing mark (210) on a printing medium (200), characterized in that at least one sensor unit (22b, 22c) which is arranged downstream of a first sensor unit (22a) in the course of printing can be moved transversely with respect to the conveying direction (F) of the printing medium (200).

Description

technical field [0001] The invention relates to a monitoring system for aligning printing units of a tandem printing machine, a correspondingly equipped tandem printing machine and a monitoring method for aligning printing units of a tandem printing machine. Background technique [0002] It is known in principle to arrange the individual printing units in series in the form of a tandem printing press. In this case, the individual printing units are supplied sequentially, so that there is a corresponding free transport length of the printing medium between the individual printing units responsible for the respective different colors. The printing medium is often provided here from a paper roll and there it is unwound and designed in the form of a web. In order to ensure that the individual colors of the individual printing units are also applied precisely in relation to one another on the printing medium, it is known to use so-called printing markers. The printed markers ar...
