Embodiment Construction

[0038] The printing unit 01 has at least one printing head 02 . The at least one printing head 02 is preferably designed as an inkjet printing head 02 . The at least one printing head 02 is preferably a printing head 02 which is arranged in a fixed position during the printing operation. The printing unit 01 preferably has at least one storage container 03 for application medium, in particular ink, and at least one balancing container 04 . The coating medium or ink is preferably fed from the storage container 03 via the compensating container 04 into the printing head 02 and emerges from the printing head 02 where it is applied to the corresponding printing material.

[0039] The compensating container 04 has at least one and preferably exactly one interior space 07 . Inner space 07 of compensating container 04 is provided in particular to accommodate at least one first liquid volume 27 of coating medium, in particular ink. Preferably, the interior 07 of the compensating co...

Abstract

The invention relates to a printing unit (01), the printing unit (01) having at least one supply container (03) for coating agent, an equalising container (04) and at least one printing head (02). Theprinting unit (01) has a main assembly (33) and a printing head assembly (34), the supply container (03) being part of the main assembly (33). The printing head assembly (34) is connected to the mainassembly (33) by at least one flexible supply connection (36). The printing head assembly (34) as a whole can be arranged in different printing positions relative to the main assembly (33). The printing head assembly (34) has at least one main body (43), the at least one printing head (02) and at least one nozzle closure (37). The at least one nozzle closure (37) and the at least one printing head (02) are movable relative to each other. The nozzle closure (37) has at least one storage element (62) for solvent.

Description

technical field [0001] The invention relates to a printing assembly. Background technique [0002] Printing cartridges having print heads are known. Printing cartridges of this type usually have a piping system by means of which ink can be supplied to the printing heads. In particular systems are known in which the printing situation in the printing head is monitored in order to achieve corresponding printing conditions. [0003] A printing cartridge is known from US 2012 / 0176429 A1, which has a printing head, an ink pump and a vacuum sensor, wherein the result of the vacuum sensor is used to activate the ink pump. [0004] A printing cartridge is known from DE 10 2014 208 896 A1, in which the ink is circulated and a constant ink level is maintained via an overflow, and the low pressure is regulated by means of at least one vacuum regulator connected to the gas line. [0005] A printing cartridge is known from US 2008 / 0273063 A1 in which ink is circulated and a plurality ...
