Abstract: An immersion-type surface treatment tank includes a treatment tank body including: a single tank internal space elongated in a plan view, and a nozzle that ejects an electrodeposition paint into the tank internal space. The treatment tank body includes: a first tank inner side surface extending along a longitudinal direction of the tank internal space; a second tank inner side surface facing the first tank inner side surface and extending along the longitudinal direction; and a rectifying plate that is formed halfway in the longitudinal direction and changes a flow direction of the electrodeposition paint such that the electrodeposition paint flowing horizontally along the first tank inner side surface is directed toward the second tank inner side surface. The rectifying plate changes the flow direction of the electrodeposition paint, thereby forming, in the tank internal space, at least two horizontal swirl flows adjacent to each other in the longitudinal direction.

Abstract: An electrostatic coating apparatus includes: a spray gun configured to spray a coating material onto a coating object; a voltage application device configured to apply a high voltage to the spray gun; and a current measurement device configured to measure electric current flowing through the spray gun. When the spray gun, which is in a state of not spraying the coating material onto the coating object and is under application of the high voltage from the voltage application device, is located at a distance from the coating object, the electric current flowing through the spray gun is measured by the current measurement device. A grounded state of the coating object is checked, based on the measured electric current. This shortens the time required for checking the grounded state, while allowing for downsizing and simplified configuration of production equipment and reduction of equipment cost.
