Title (EN) ELECTROSTATIC COATING SYSTEM
(FR) INSTALLATION DE REVETEMENT ELECTROSTATIQUE
Abstract: front page image
(EN)An electrostatic coating system in which the workpiece (11) to be coated is charged to a high DC potential. A conveyor (10) moves the workpiece (11) through a coating zone. A separate charge collector disc (22) on the workpiece support (15) passes close to but does not contact a charged conductor (31). An electrostatic charge is induced on the disc (22) and is transferred to the workpiece (11). The conveyor (10) is grounded and the workpiece support (15) is connected to the conveyor (10) through a high resistance which completes the charging circuit and drains the charge from the workpiece (11) and support (15) as they leave the coating zone. The ends (31a, 31b) of the charged conductor are curved away from the path of the charge collector (22). Insulating plates (49, 50) shield the conductor (31) and limit swinging of the workpiece support (15).
(FR)Dans l"installation de revetement electrostatique, la piece (11) a recouvrir est mise a un potentiel continu eleve. Un convoyeur (10) deplace la piece a travers la zone de revetement. Un disque (22) collecteur de charge, place sur le support (15) de la piece, passe a proximite d"un conducteur charge (31) sans le toucher. Une charge electrostatique est induite sur le disque (22) et est transferee a la piece (11). Le convoyeur (10) est mis a la masse et le support (15) est connecte au convoyeur (10) par une resistance elevee qui complete le circuit de charge et draine la charge de la piece (11) et du support (15) lorsqu"ils quittent la zone de revetement. Les extremites (31a, 31b) du conducteur charge sont courbees dans une direction s"eloignant du chemin du disque (22). Des plaques isolantes (49, 50) protegent le conducteur (31) et limitent les deplacements du support (15).
