Abstract

A system for coating targets, e.g. automobile bodies (18) on a conveyor, with a coating material chosen from multiple coating materials of various colors end types. The deposition of the coating material on the targets is aided by electrical forces established between an electrode which surrounds a rotating atomizing device (10,12,14,20,22,24,28, 30,32) to which a stream of the selected coating material is supplied for atomization. A cylindrical sleeve (102) surrounds the rotating atomizing device (10,12,14,20,22,24,28,30,32) and lies between the electrode (116), which is in the shape of a ring (116), and the rotating atomizing device (10,12,14,20,22,24,28,30,32). The atomizing device (10,12,14,20,22,24,28,30,32) extends from an opening at one end of the sleeve (102), and the structure which supports the atomizing device (10,12,14,20,22,24,28,30,32) adjacent the conveyor extends from the other end of the sleeve (102). The ring (116) lies approximately equidistant from the two ends of the sleeve (102) to reduce the likelihood of electrical discharge between the electrode (116) and the atomizing device (10,12,14,20,22,24,28,30,32) or its supporting structure. The atomizing device (10,12,14,20,22,24,28,30,32) is maintained at ground potential. A power supply (100) is provided for maintaining an electrical potential between the ring (116) and the target (34) with the electrical potential being of a sufficiently high magnitude to charge the atomized coating material particles by discharge from the ring (114), and to maintain a potential difference between the atomized and charged particles and the target (34). Electrical forces repel the charged particles away from the ring (116) and propel them toward the target (34) to insure suitable deposition efficiency of the atomized coating material on the target (34).
