Embodiment Construction

[0038] exist figure 1 In , the cleaning head is denoted by reference numeral 1 . The cleaning head 1 is designed for cleaning electronic printing heads which operate according to the inkjet principle. These printing heads, which are used, for example, in devices for printing containers, comprise a plurality of nozzles arranged one above the other vertically, and by means of these nozzles the printing ink in the form of droplets can be output in each case. In order to clean the nozzles of the print head (in particular residues resulting from ink deposition), a cleaning fluid is applied by means of the cleaning head 1 to the area of ​​the print head where the nozzles are located, so that the residues are dissolved and removed by this cleaning fluid .

[0039] The cleaning head 1 comprises an end side 1.1 which faces the printing head during cleaning. In particular, the end face 1.1 is arranged at a short distance from the nozzles of the printing head, for example at a distanc...

Abstract

A cleaning head includes an end face that faces an inkjet print head to be cleaned. A supply opening and a discharge opening are spaced apart on the end face. A supply channel carries cleaning fluid to the supply opening. The discharge opening receives cleaning fluid that is to be conveyed away after having been emitted through the supply opening. The cleaning head emits a cleaning fluid jet through the supply opening with the cleaning fluid jet being emitted in a direction having a component that is directed towards the discharge opening so that the cleaning fluid can be conveyed away by suction through the discharge opening.

Description

technical field [0001] The present invention relates to a cleaning head, and to an apparatus and method for cleaning a printing head. Background technique [0002] Devices for printing containers are known in various embodiments. In particular, printing systems are known which print containers with digital motorized print heads operating on the inkjet principle. Here, in particular printing systems or printing machines are known (for example DE 10 2007 050 490 A1), in which printing systems or printing machines are formed on transport elements driven to rotate around at least one vertical axis. Several processing stations or printing stations each receive the containers to be printed, and in these printing systems or printing presses the containers are printed with electronically controllable digital print heads operating on the inkjet principle. These print heads comprise a plurality of nozzles arranged in one or more rows, by means of which nozzles the printing ink is ap...
