Problems solved by technology

[0003] The problem here is that, especially when suctioning cleaning fluid and ink residues, you have to work at relatively precise intervals in order to avoid damage to the printing nozzles and to avoid suctioning ink from the printing nozzles
Additionally, jetting the printhead often results in contamination of the cleaning station and / or around the printhead due to sprayed and / or splashed ink residue

Embodiment Construction

[0045] if possible by figure 1 As can be seen, the cleaning station 100 in a preferred embodiment comprises vertically movable cleaning heads 1 , 2 , 3 for cleaning horizontally movable printing heads 4 , 5 , 6 . Print head 4, 5, 6 in figure 1 The center is partially covered by cleaning heads 1, 2, 3.

[0046] The cleaning heads 1 , 2 , 3 are fastened to lifting devices 7 , 8 and can be lifted from the parking positions 9 , 10 into the cleaning areas 11 , 12 , 13 on these lifting devices, ie essentially to the associated printing heads. 4, 5, 6 heights.

[0047] Preferably, the first cleaning head 1 and the second cleaning head 2 are arranged stationary one above the other and can move jointly on the first lifting device 7 . This first lifting device comprises, for example, a pneumatically driven multi-position cylinder 7a with a mover 7b and a first vertical linear guide 7c.

[0048] By means of the multi-position cylinder 7a, the first cleaning head 1 can be lifted in th...

Abstract

A cleaning station for a direct printing station is described, which has at least, in particular vertically movable, cleaning head for cleaning at least one printing head. Here, the cleaning head includes a cleaning nozzle for ejecting cleaning fluid and a suction nozzle for sucking cleaning fluid from the printing head. Since the cleaning head also includes at least one spacer roller, which in particular protrudes beyond the suction nozzle for maintaining a minimum distance between the suction nozzle and the printing head, it is possible to maintain a constant and effective suction between the suction nozzle and the printing head. The spacing between the nozzles enables a contact-free suction relative to the printing nozzles present on the printing head.

Description

technical field [0001] The invention relates to a cleaning station according to the preamble of claim 1 and to a direct printing machine having such a cleaning station. Background technique [0002] Print heads for inkjet direct printing on containers usually have a plurality of fine print nozzles which must be cleaned regularly to ensure a flawless printed image on the container to be printed. For this purpose, a cleaning station is known from DE 10 2013 217 685 A1, which is fastened in the region of a direct printing press in order to clean the printing heads on the direct printing press. In this case, up to two horizontally displaceable print heads arranged one above the other can be moved in parallel to the cleaning station and cleaned there. The printing head is then sprayed, for example, with a cleaning liquid, which is wiped off with a wiper lip from the printing nozzles and sucked in, and the cleaning liquid with ink residues removed in this way is collected and fin...
