INK-JET TYPE VEHICLE COATING MACHINE AND VEHICLE COATING METHOD

Title:

INK-JET TYPE VEHICLE COATING MACHINE AND VEHICLE COATING METHOD

Document Type and Number:

WIPO Patent Application WO/2021/205537

Kind Code:

A1

Abstract:

Provided are an ink-jet type vehicle coating machine and an ink-jet type vehicle coating method that enable formation of a uniform coating film thickness at a coating portion including an end of a vehicle.　In a state where a longitudinal direction of a nozzle head 53 is orthogonal to a scanning direction, a first nozzle array 55A and a second nozzle array 55B are disposed such that droplets discharged from nozzles 54 of the second nozzle array 55B are discharged to intermediate portions between droplets discharged from nozzles 54 adjacent to each other in the first nozzle array 55A. In addition, on the basis of trajectory data for moving the nozzle head 53, attitude data for keeping the longitudinal direction of the nozzle head 53 perpendicular to a main scanning direction of the nozzle head 53 is formed. An arm control unit 110 controls a robot arm on the basis of the trajectory data and attitude data such that, in a state where the nozzle head 53 performs coating while moving in the main scanning direction, the longitudinal direction of the nozzle head 53 is kept perpendicular to the main scanning direction.
