Embodiment Construction

[0029] figure 1 The spatial view of is given an overview of the mounting device 40 and its structure. The mounting device 40 serves to receive the printing head 31 in a calibratable manner. For this purpose, the mounting device 40 has a frame 42 which can be fastened to a rigid carrier 41 . The rigid carrier 41 may be part of the frame of the digital printing machine 10 . The printing head 31 is received by the frame 42 in such a way that the area of ​​the frame 42 surrounds the sides of the printing head 31 , ie the printing head 31 is arranged in the center of the frame 42 . The printing head 31 has a nozzle plate 32 on its lower end, which protrudes beyond the frame 42 of the mounting device 40 and wherein the nozzles of the nozzle plate 32 are able to discharge the smallest ink drops, It is used to print an image on a sheet 100 (not further shown) below the printing head 31 . The control lines and the ink supply of the printing head 31 are not further shown in the figu...

Abstract

The invention relates to a mounting device for printing heads and a printing system which enable simple replacement and simple and reliable calibration of printing heads. The mounting device (40) has a rigid carrier (41) and a frame (42) for receiving a printing head (31), wherein the frame (42) is detachably fastened to the rigid carrier (41) , and wherein said frame (42) has alignment means (43, 44, 45) for aligning said printing head (31) relative to said rigid carrier (41). According to the invention, the alignment device of said frame (42) has two solid articulations (43, 44) and two actuators (45) for ) and a rotation (r) about the vertical axis (z) to calibrate the print head (31).

Description

technical field [0001] The invention relates to a mounting device for a printing head, a mounting device with a plurality of mounting devices and a printing system. Background technique [0002] The use of digital printing presses is known for printing sheets and webs made of paper, cardboard and cardboard in small runs or with individual printing themes. In the case of an inkjet head, the transport system moves the individual printing materials past under the inkjet head with minimal spacing. Revolving conveyor belts (eg, designed as suction belts) and rotating drums (so-called inkjet rollers) or revolving trays are known as sheet transport systems. [0003] In a machine concept using a cylinder, such as that described in DE 10 2015 211 440 B3, a plurality of inkjet print heads are arranged radially spaced above the inkjet cylinder, which print the Sheets that the print head moves past at small intervals. Multiple sheets can be sucked and transported simultaneously on on...
