Abstract: 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.

Abstract: A spray booth for spraying pieces to be painted with a painting product includes a system that conveys the pieces to be painted inside the booth, a supplying circuit that supplies a painting product or solvent to painting tools, a plenum, a mobile wall providing access to the inside of the spray booth, optionally a reading system for the pieces to be painted, optionally a filtering system, a plurality of spraying tools that include one or more a spray guns each placed on an independent arm moving on a plane and optionally in a vertical direction, one or more cleaning stations, placed in correspondence of the mobile wall and provided with a drawer that is mobile between rest and a cleaning positions and that includes a painting product or solvent draining tube having a mouth, a slot for supplying compressed air, and a brush for brushing the spray guns.

Abstract: 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.

Abstract: Spray booth (21) for applying paint on basically flat parts (22), said spray booth having a plenum (24) and comprising a conveying system (25) for conveying the flat parts (22) to be painted, at least a device (23) for applying paint on said moving parts, and at least a suction system, wherein the plenum (24) of the spray booth has a semi-cylindrical shape, having its axis perpendicular to the direction of the advancing part (22).

Abstract: A paint spraying machine includes an apparatus for containing and removing the leakage of paint drops from a rotating joint, without the risk of damaging the article being sprayed, and thus without the need for downtime to replace sealing elements. The rotating joint includes a hollow shaft for distributing paint, a drum including a plurality of flanges that define separate chambers for different paints, a plurality of seals for separating the different paints in the different chambers which together form a high-pressure circuit, a low-pressure circuit to refrigerate the seals, improve their sealing and possibly intercept leaking paint, and a plurality of centering rings provide for correct assembly of the seals and the correct alignment of different flanges. The rings are hollow, and allow for the passage of the refrigerating/cleaning liquid under low pressure.
