摘要： An apparatus for transferring electrically conductive coating materials such as water-based paint from a source to an electrostatically charged dispenser includes first and second shuttle devices and two large reservoir, piston pumps each having structure for preventing contamination of the coating material and pressure build-up at their piston heads. The first shuttle device is movable between a neutral position wherein it is electrically isolated from a filling station connected to the coating material source, and a transfer position wherein coating material is transmitted to one of the piston pumps through a coupling device which connects the filling station and first shuttle. The second shuttle device is movable with respect to a discharge station between a neutral position wherein the second shuttle is spaced from the discharge station, and a transfer position wherein coating material is transmitted from the filled piston pump, through another coupling device which connects the second shuttle and discharge station and then to the second piston pump for transmission to one or more electrostatic coating dispensers. Movement of the shuttle is controlled to maintain one of the shuttles in the neutral position while the other is at the transfer position.

摘要： An apparatus is provided for transferring electrically conductive coating materials, such as water-based paint, from at least one source to one or more coating dispensers for discharge onto a substrate. One voltage block is provided to avoid the creation of an electrical path between one or more sources of coating material and the coating material which is electrostatically charged during a coating operation, and a secondary voltage block is provided between each of a number of individual spray guns and the charged coating material so that each spray gun can be electrically isolated from the charged coating material when not in use. The apparatus is optionally provided with a color changer, and/or a heater which is electrically isolated from the charged coating material and is effective to elevate the temperature of the coating material prior to discharge from the spray guns.

摘要： Objects which have been abraded are coated with a coating material which is normally solid at room temperatures. The material is liquified at elevated temperatures and sprayed onto the cooler objects in a heated cabinet, whereupon the material at least partially solidifies on the object. Thereafter, heat is applied to the coating material to cause it to flow out over the coat surface. A cooled conveyor system prevents disruption of the coating material. Overspray is maintained in liquified form within the cabinet where it is reclaimed and flows to a heated sump for direct recirculation to the spray apparatus. There are no deleterious solvent emissions. Apparatus and methods are provided.

摘要： Electrostatic coating apparatus including apparatus for establishing an electrostatic field for indirectly charging atomized droplets of paint or other coating material discharged from an atomizer. A flexible tube is formed into an annulus and is positioned coaxially with the atomizer. Pins extend through the tube and have short ends which project towards a workpiece to be coated. The tube is formed from an insulating outer layer and a semi-conducting inner layer having a high distributed resistance. The pins extend through the inner layer which is connected through a large resistance to a high voltage power supply. The apparatus is particularly useful for charging electrically conductive and semi-conductive materials delivered to the atomizer from a grounded source.
