Abstract:
The rotary atomizing coating device (1) is provided with a spray head (2) formed of a tube body having a circular truncated conical shape and constituted to spray, from an opening end on the large diameter side, a coating introduced from an opening end on the small diameter side thereof, and a coating supply machine (3) engaged with the spray head (2) for supplying the coating while rotating the spray head (2) around an axial line (O). The spray head (2) has a first coating diffusion part (28) having a curved surface with a convex shape towards the axial line (O) on the inner peripheral surface, and a second coating diffusion part (29) extending to an outer edge (26) of the opening end on the large diameter side having a curved surface with a concave shape towards the axial line (O) with grooves (4) on the outer edge (26).

Abstract:
The invention provides an intermediate storage device of an electrostatic coating system that can clean efficiently, a method for cleaning the same, and a method for coating. An intermediate storage device 10 comprises: a first hole 141 which is open to a cylinder chamber 14 and is connected to a paint supply source; a second hole 142 which is open to the cylinder chamber 14 and is connected to a coating gun; and a switch means which switches between a first cleaning which cleans the cylinder chamber 14 by supplying cleaning fluid W from the first hole 141 and discharging from the second hole 142 waste fluid that has undergone cleaning and a second cleaning which cleans the cylinder chamber 14 by supplying cleaning fluid W from the second hole 142 and discharging from the first hole 141 waste fluid that has undergone cleaning.

Abstract:
An electrostatic painting apparatus includes a painting gun having at one end thereof a paint spray section, and a connection section detachably connectable to an external paint supply section for receiving a supply of paint from the supply section and supplying the received paint to a paint storage section that stores and supplies the supplied paint to the painting gun. The connection section is surrounded and protected by a peripheral wall, so that paint can pass by the other end of the painting gun without reaching the connection section. Consequently, the connection section can be prevented from being undesirably smeared with the paint.
