(54) | Electrostatic coating facility for electroconductive coating material |
(57) An electrostatic coating facility for an electroconductive coating material comprising
a coating machine disposed in a coating zone while being grounded to the earth, an
insulated conveyer disposed in the coating zone for conveying an object to be coated
in an electrically insulated state and applying a high voltage to the object, an entering
conveyer disposed for carrying the object into the coating zone, a delivery conveyer
for carrying the coated object out of the coating zone, and a relay transfer device
interposed between the insulated conveyer 1 and the entering conveyer or the delivery
conveyer for transferring the object in an electrically insulated state while keeping
a required insulation distance between each of them. Aqueous coating material free
from public pollution can be used with no troubles for taking insulative measures
on the side of the coating machine and without worry of spark discharge. |
