Apparatus (1) for applying paint comprises a device (40) for applying paint that comprises a plurality of spray guns (26) that is movable along a closed path having two parallel sides connected by two circular arcs, a rotating joint (43) for supplying paint provided with a distributor and comprising a plurality of tube-support chains (44), each tube support chain (44) connecting the distributor of the one rotating joint (43) for dispensing the painting product to a respective gun of said spray guns (26), in which each tube support chain (44) has an inverted U-shape provided with two ends, of which—the first end is connected to a first rotating support (61), which is connected to the rotating joint (43) and follows a circular trajectory, while—the second end is connected to a second rotating support (62), which is connected to a support arm (41) of a respective gun (26) and follows in use the trajectory defined by said closed path.

Apparatus for painting mainly flat products including a spray booth, in its turn including a plenum, a conveying belt for conveying products at least a device for applying paint, and at least one suction plant, wherein the plenum of the spray booth has a symmetric M-shape including, from the respective peripheries to the centre of the plenum: two first descending surface portions tilted towards the periphery; two second lateral surface portions parallel to the belt; two third descending surface portions, with a tilt towards the centre, opposite the tilt of the first portions; a fourth central surface portion parallel to said belt, the fourth central surface portion being closer to the conveying belt than the lateral parallel sections.

A coating system includes a coating robot and an operation robot. The coating robot has a height and is mounted in a coating booth to coat a workpiece while the workpiece is conveyed in the coating booth in a conveyance direction substantially perpendicular to a height direction. The workpiece including a body and a movable part movable with respect to the body. The operation robot is disposed in the coating booth below the coating robot in the height direction. The operation robot is movable in the coating booth in the conveyance direction and is configured to move the movable part of the workpiece.

A coating system including a coating robot and a movable opener robot. The coating robot has a fixed base fixedly mounted to a coating booth, and a first arm rotatably coupled to the fixed base about a first axis substantially parallel to a conveyance direction of a workpiece that includes a body and a first movable member. The body has a body inner surface and the first movable member has a first movable member inner surface. The movable opener robot has a movable base mounted such that the movable opener robot is movable in the coating booth in the conveyance direction. The movable base is mounted below the fixed base. The movable opener robot can open the first movable member of the workpiece. The coating robot can coat the body inner surface and the first movable member inner surface when the first movable member has been opened.
