CLEANING DEVICE

摘要

Provided is a cleaning device that can reduce maintenance-time while injecting a cleaning solution into a gap between head modules so that the cleaning solution or the like is not sucked into an inkjet head. The position of the inkjet head relative to a spray-nozzle is moved in one direction. When relative movement is performed, the relative movement is temporarily stopped or moving speed of the relative movement is reduced at a position where the gap between the head modules faces at least the spray-nozzle. The cleaning solution is sprayed to the gap at a time when the relative movement is temporarily stopped or when the moving speed of the relative movement is reduced. A removing member removing the cleaning solution present in the gap, is provided at a position separated from the spray-nozzle in the one direction by a distance of n times a pitch of the gaps.

主权项

1. A cleaning device comprising:
a spray nozzle that sprays a cleaning solution to an ink ejection surface of an ink jet head in which a plurality of head modules are joined to each other in one direction; a relative movement unit that moves the position of the ink jet head relative to the spray nozzle in the one direction; a movement controller that temporarily stops relative movement performed by the relative movement unit or reduces moving speed of the relative movement at a position where a gap between the head modules faces at least the spray nozzle in a case in which the relative movement performed by the relative movement unit is performed; a nozzle controller that allows the cleaning solution to be sprayed to the gap from the spray nozzle at a time in a case in which the relative movement performed by the relative movement unit is temporarily stopped or at a time in a case in which the moving speed of the relative movement is reduced; and a removing member that is disposed at a position separated from the spray nozzle in the one direction by a distance of n times a pitch of the gaps in a case in which n is a natural number of 1 or more, and removes the cleaning solution present in the gap.
