Abstract:
1. An inkjet coating device comprising: an upstream guide roller adapted to wind off and then convey a rolled film, the rolled film having a longitudinal direction corresponding to an X-axis direction, and the rolled film having a width direction corresponding to a Y-axis direction; a suction table adapted to hold by sucking the film thus wound off; an inkjet coating head adapted to apply a liquid UV-curing coating material to a surface of the film thus held by sucking on the suction table; a gantry structure adapted to allow the coating head to move above the film in a plane defined by an X axis and an Y axis; a Z-axis drive section adapted to allow the coating head to move vertically; an ultraviolet light source capable of moving integrally with the coating head in X, Y, and z axis directions; a downstream guide roller adapted to wind up the film to form a roll; a vacuum suction section located at a position outside a film conveying range, having a suction port having contact with the coating head when the coating head moves to the position and then moves downward, and adapted to suck nozzles of the coating head through the suction port, the vacuum suction section configured to be reciprocated in the Y-axis direction of the film; and a light blocking section adapted to block incidence of ultraviolet light from the ultraviolet light source to the inside of the vacuum suction section, wherein block of the ultraviolet light and release of the block can be selected by reciprocating the vacuum suction section in the Y-axis direction relative to the light blocking section, and wherein the light blocking section is disposed at a fixed position a predetermined distance from the suction table in the Y-axis direction.
