A non-contact cleaner for a paint spray equivalent having a housing with an open top with a venturi opening. A ring is contained the housing in a space downwardly from the entry opening thus forming a chamber between the ring and the venturi opening adapted to receive the paint spray tip to be cleaned. A plurality of circumferently spaced air nozzles created downward airflow through the housing while a solvent nozzle contained in the housing sprays solvent onto the paint tip to be cleaned.

A dispensing device includes a dispensing mechanism and a calibration mechanism coupled to the dispensing mechanism. The calibration mechanism includes a control unit. The control unit is configured to detect a position difference between a dispensing needle and a reference coordinate in a direction. The dispensing mechanism is configured to adjust the dispensing needle in the direction according to the position difference.

A liquid processing apparatus includes a processing liquid supply including a nozzle configured to discharge a processing liquid; a nozzle mover configured to move the nozzle between a coating position and a standby position; a suction unit including a suction opening toward a leading end surface of the nozzle located at the standby position; a cleaning unit configured to clean the leading end surface of the nozzle located at the standby position with a cleaning liquid; and a control device. The control device controls the processing liquid supply to discharge the processing liquid in a state that the nozzle is located at the standby position. The control device controls the suction unit to suck the processing liquid. The control device controls the cleaning unit to supply the cleaning liquid toward the standby position to clean the nozzle. The control device controls the suction unit to suck the cleaning liquid.

A processing apparatus includes a processing chamber cover having a first transverse member extending from between a first side plate and a first delivery port defined in the first side plate outwardly of a first processing chamber. The width of a gap between the first transverse member and a pedestal positioned in the first delivery port when a workpiece is processed in the first processing chamber, i.e., the length of the gap along the direction toward the outside of the processing chamber, is large. When processing water that is scattered passes through the gap, the processing water will likely contact the pedestal or the first transverse member and stay in the gap. As a result, the processing water is effectively prevented from being scattered out of the first processing chamber by a simple structure, compared with water supply means for forming a water film in the gap.

A dispensing system for dispensing a fluid, the fluid being water or a water-based mixture, includes a dispensing unit and a cleaning unit. The dispensing unit includes a connection unit for connecting the dispensing unit to a supply of the fluid, a dispensing head for dispensing the fluid, and a flexible hose for guiding the fluid from the connection unit to the dispensing head. The cleaning unit includes a cleaning attachment unit for attaching the cleaning unit to the connection unit, a cleaning fluid delivery unit configured to deliver cleaning fluid to the dispensing unit via the cleaning attachment unit, and a receptacle unit configured to accommodate the dispensing head and to receive fluids exiting the dispensing head.

A cleaning device includes a box body, a cleaning nozzle that ejects cleaning liquid toward a paint gun, an air nozzle hole that is configured to eject air toward the paint gun, and an eaves portion that protrudes more toward a central axis line of the insertion hole than the air nozzle hole. A method of cleaning the paint gun includes ejecting cleaning liquid from the cleaning nozzle toward the paint gun. In the ejecting, air is ejected toward the paint gun from the air nozzle hole.
