    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.

    Abstract: An electrostatic coating apparatus includes a coating gun that sprays a coating material toward a coated matter, a high-voltage application apparatus that applies a high voltage to the coating gun, a bell-side current calculation unit that calculates a bell-side current to flow from the coating gun to the coated matter, an earth-side current measurement unit that measures an earth-side current to flow from the coated matter to the earth, and an earth check unit that detects an abnormal earth state of the coated matter, depending on a magnitude relation between the bell-side current calculated at the time of electrostatic coating and the bell-side current when the earth is properly connected, and a magnitude relation between the earth-side current measured at the time of the electrostatic coating and the earth-side current when the earth is properly connected.
