Abstract:
An electrostatic powder coating installation incorporating a cabin in which there are arranged means connected with a supply container for the delivery of electrostatically charged powder. A part of the internal compartment of the cabin is limited by one side or face of a filter moving through the cabin, the other face of which confronts the suction side of a suction device effective through the filter at the aforementioned internal compartment. A cleaning device is operatively associated with the filter in order to remove therefrom excess powder deposited thereon. The cleaning device embodies a suction nozzle directed towards the one face of the filter and which while interposing a separator is operatively connected with the suction side of a suction blower. The outlet of the separator is connected with a supply container. The method of operating the installation entails depositing fresh powder upon a section of the filter located in front of the suction nozzle for the purpose of replacing the powder consumed during the coating operation.
Abstract:
An electrostatic powder coating installation incorporating a cabin serving to house the articles to be coated, the internal space of the cabin being connected with a suction device. Further, there is provided a filter which bounds with one face or side thereof a part of the internal space of the cabin and with its other side or face confronts the inlet of the suction device. A cleaning device is operatively associated with the filter and movable relative thereto, this cleaning device removing from the filter the excess powder deposited upon the filter and delivering such to a collecting container.
Abstract:
SPRAYING APPARATUS FOR AUTOMATICALLY COATING WORKPIECES WITH COATING MATERIAL APPLIED BY MEANS OF A SPRAY GUN THE APPARATUS INCLUDING A CARRIER HEADS ON WHICH A SPRAY GUN IS MOUNTED FOR PIVOTING MOVEMENT IN A VERTICAL PLANE. THE CARRIER HEAD IS MOUNTED ON A LIFTING STAND FOR VERTICAL UP AND DOWN MOVEMENT AND THE LIFTING STAND IS PLACED ON CARRIAGE MEANS FOR MOVEMENT IN A HORIZONTAL PLANE IN TWO DIRECTIONS AT RIGHT ANGLES TO EACH OTHER. THE MOVEMENTS OF THE SPRAY GUN, LIFTING STAND AND CARRIAGE MEANS ARE EFFECTED BY MOTORS CONTROLLED BY PROGRAM CONTROL DEVICES ADAPTED TO BE SET TO PRODUCE A SEQUENCE OF OPERATING STEPS OF THE SPRAY GUN, LIFTING STAND AND CARRIAGE MEANS.
