Process and station for changing product in an installation for spraying coating product

A process for changing product in an installation for spraying coating product, the installation comprising at least one robot adapted to displace a first sprayer opposite objects (3) to be coated, a first reservoir being associated with, and forming a first sub-assembly with, the first sprayer, said process comprising:

• bringing the first reservoir towards an area of a cleaning/filling station,
• separating the first sub-assembly with respect to the robot,
• connecting a second sub-assembly, similar to the first sub-assembly, with the robot, the second sub-assembly being adapted to be used for spraying coating product during cleaning and/or filling of the first reservoir and the first sprayer, and
• cleaning and/or filling the first reservoir and the first sprayer in the area;
• characterized in that said method further comprises:
• positioning a coating product supply unit equipped with a plurality of outlets by displacing the unit in a first direction so that a predetermined outlet of the unit is disposed opposite the first sub-assembly;
• and
• displacing, in a second direction substantially perpendicular to said first direction, a structure defining at least two areas for receiving the first sub-assembly so as to reach a position of connection of the first sub-assembly with the coating product supply unit.
