ABSTRACT:
A cleaning apparatus for ultrasonically cleaning workpieces has an array of juxtaposed tanks including an ultrasonic cleaning tank, and a plurality of supports associated with the respective tanks for vertical movement between lower positions in the tanks and upper positions above the tanks. The tanks are separably joined so that they are selectively replaceable with other tanks. The supports support workpieces processed in the tanks, respectively, for sliding movement toward adjacent ones of the tanks. A lifting and lowering mechanism simultaneously lowers the supports into the tanks, respectively, to allow the workpieces to be processed in the tanks, and simultaneously lifts the supports from the lower positions in the tanks up to the upper positions above the tanks after the workpieces supported on the supports lowered in the tanks are processed in the tanks. The workpieces supported on the supports are simultaneously slid by a feed mechanism onto the supports associated with adjacent ones of the tanks while the supports are being lifted to the upper positions.
