Device to clean a component of deposits
In a device to clean a component of deposits, at least one first nozzle unit is positioned to spray a fluid at an angle onto a surface of the component that is to be cleaned, the first nozzle unit being provided opposite a border region of the surface of the component that is to be cleaned. At least one second nozzle unit generates a flow of a gaseous medium over the surface to be cleaned and is provided adjacent to edge of the border region of the surface of the component that is to be cleaned.
1. An ink head cleaning system, comprising:
a cleaning device and an ink residue cleaning element;
said ink residue cleaning element removing ink residues from a print head, said cleaning element having an edge with an adjacent border region where the removed ink residues are collected, said border region being part of and located at one end of a surface to be cleaned on the cleaning element, said cleaning element having another end opposite said one end;
said cleaning device comprising a fluid spray nozzle directing a fluid spray during a cleaning interval in a first direction onto said border region of the cleaning element adjacent said edge;
said cleaning device further comprising a gaseous medium flow nozzle directing a gaseous medium flow in a second direction substantially different than said first direction substantially toward but above said edge and onto and across said border region to blow the cleaning fluid and collected ink residues from said border region across remaining portions of said surface adjacent said border region to be cleaned such that a mixture of said cleaning fluid with said collected ink residues exits said surface to be cleaned at said another end of said surface to be cleaned opposite said one end; and
said cleaning device further comprising a capturing unit arranged after said surface to be cleaned as viewed in a flow direction of a gaseous medium flow for collecting said mixture of said ink residues and cleaning fluid exiting at said another end.
2. The cleaning system of claim 1 in which the capture unit has a perforated plate at which the mixture strikes, and the perforated plate having holes of such a size that at least a portion of the mixture passes through the holes.
3. The cleaning system according to claim 2 in which a deflection plate is provided with which the perforated plate forms a container, and the deflection plate is positioned such that the mixture portion passing through the perforated plate strikes the deflection plate.
4. The cleaning system according to claim 3 in which the container has at least one end at which is located at least one first strip spaced at a distance from the perforated plate, said first strip being designed such that portions of said mixture rebounding from the perforated plate strike the first strip.
5. The cleaning system according to claim 4 in which a second, more narrow strip is provided adjacent and parallel to the first strip, said second strip partially overlapping the first strip and being designed such that mixture portions rebounding from the first strip strike the second strip.
6. The cleaning system according to claim 1 in which the fluid spray nozzle is arranged relative to the surface to be cleaned such that the fluid spray strikes the surface to be cleaned at an angle of substantially 90°.
