Embodiment Construction
[0094] First of all, it is provided that in the figures identical parts are provided with the same reference symbols or the same component designations, wherein the disclosure content contained in the entire description can be transferred to On the same part of the component name.
[0095] figure 1 In a side view, a ceramic printing medium 101 is conveyed from a conveyor 131 to the conveying device 121 of the printing system 100 and conveyed along the conveying direction T into the range of action of the printing head 103 of the printing system 100 And it is transported out of this range of action again. The printing medium 101 is conveyed in the printing system 100 by means of a continuous conveyor belt 123 of a conveying device 121 . In this case, the conveyor 131 transports ceramic printing media 101 , which were produced in a previous step by a pressing device and which have a temperature of more than 50° C. after one or more passing pretreatment stations. temperature a...

The invention relates to a method for feeding print media (101) one by one into and out of an active range of a print head (103) and for cleaning at least one part of at least one nozzle front plate (105) arranged on the print head (103), the method comprises the following steps: a) providing a printing system (100) comprising a printing head (103) with a nozzle front plate (105), the printing head (103) comprising at least one printing module (107) with at least one nozzle plate (109) from which droplets of a printable component can be output; b) conveying the printing medium (101) in the conveying direction (T) in such a way that the printing medium (101) is conveyed into and out of the active range of the nozzle front plate (105); c) cleaning at least a portion of the nozzle front plate (105) by means of one or more fluid flow arrangements (111) from the cleaning device (114) activating the fluid flow, the fluid flow arrangements (111) comprising at least one fluid flow directed towards the at least a portion of the nozzle front plate (105), the nozzle front plate (105) comprising a nozzle plate (109), the nozzle plate (109) comprising at least one fluid flow directed towards the at least a portion of the nozzle front plate (105). At least some of the printing media (101) are conveyed in the conveying direction (T) at a distance from at least one of the nearest adjacent printing media (101), whereby a gap (L) is created in the conveying direction (T) between the adjacent printing media (101) which are spaced apart, and the cleaning device (114) does not need to always activate the fluid flow, but only in the region of the gap (L) and in synchronization with the gap.
Description
technical field [0001] The invention relates to a method for conveying piece-by-piece printing media into and out of the reach of a print head and for cleaning at least a part of at least one nozzle front plate arranged on the print head Methods. Furthermore, the invention relates to a printing system for carrying out the method according to the invention. Background technique [0002] The printing system is capable of printing on different printing media, such as for example ceramic tiles, paper, corrugated cardboard, metal, wood or glass, using a printing head which typically comprises a plurality of printing modules with belt A plurality of nozzle plates with nozzles from which droplets of the printable composition can be output. In any event, the nozzle plate must be cleaned from time to time in order to be able to achieve trouble-free printing runs, wherein the production of defect-free printed printing media is of great importance. [0003] If, for example, the surf...
