    Abstract: A spray gun for electrostatic painting in which an external electrode sustaining a high voltage can be fixed/removed while sustaining insulation from a spray unit on the ground potential side by limiting current supply to paint appropriately when electrostatic painting is performed using conductive paint, e.g. water based paint, and safety and handling performance are enhanced while ensuring the painting efficiency as the spray gun for electrostatic painting. On the outside of the spray gun (1) having the spray unit (5) at the forward end thereof, the external electrode (7) having an electrode projecting from the forward end part thereof is provided removably at the part (13) of the gun body being connected with the electrode while being separated from the paint passage such that it can be replaced readily. The part being connected with a high voltage output end part through a high resistor for limiting current can be shortened while sustaining safety by providing a turn-up part so that a sufficient creeping discharge preventing distance is ensured up to the exposed part on the outer surface. Furthermore, the electrode body itself is simplified so that it can be replaced with one touch, and it is composed of a flexible resilient material in order to prevent damage.

    Abstract: PROBLEM TO BE SOLVED: To improve increase in danger caused by high voltage charging, a large size and increase in weight by coping with voltage resistance strength of an electrostatic coating machine, by controlling an output by inhibiting the high voltage charged in electrostatic coating to a voltage always required and to realize coating excellent in safety and handling/operation.
    SOLUTION: In feed control of electrostatic coating high voltage, the high voltage is fed to a charging electrode 2 of the electrostatic coating machine 1 and coating deposition efficiency to an object to be coated 8 is enhanced by static electric force. The fed voltage is restricted to the required voltage value or less to control the output against the output of a high voltage generator 3 for outputting a discharging current from the charging electrode 2 at the required voltage when the current value does not arrive at the discharging current. The fed high voltage is controlled by a primary power source output voltage of the high voltage generator 3. The required voltage is -30 to -70 kV and the preferable current required is 80 to 150 μA.

    Abstract: PROBLEM TO BE SOLVED: To provide a high voltage generator incorporated in a spray gun which is made small-sized and lightweight, since the spray gun has to be made small-sized and the operability in use has to be improved under the consideration for the use of higher voltage and the danger therefor in the case of external charging electrostatic coating.
    SOLUTION: The direct current high voltage generator used for an external charging electrostatic coating gun is provided with an atomizer and a charging electrode which is separated from the path of coating material supplied to the atomizer and is disposed outside the atomizer. Therein, a step-up transformer and a multi-stage voltage doubler rectifier circuit are arranged in piles and a plurality of resistors are bundled in the longitudinal direction and are connected in series to constitute a limiting resistance of 100∼400MΩ. Further, the step-up transformer, the multi-stage voltage doubler rectifier circuit and the resistors are molded into one body by using an insulating resin.

    Abstract: PROBLEM TO BE SOLVED: To provide an external charging type electrostatic coating gun which exhibits a high electrostatic coating effect and safety within a range where the gun is practically usable by determining a position of an external electrode, relative to an atomizer, for maintaining a high voltage by restricting the electric current to a conductive paint to be supplied in electrostatic coating of the paint.
    SOLUTION: The external electrode is disposed apart from a paint route and on the outer side of a spray gun having the atomizer at its distal end, and the distal end is positioned before the atomization position of the atomizer and as near the gun as possible while avoiding a mist flow within a range where the necessary voltage is maintained and the dangerous electric current is not exceeded. The external electrode is provided with a high-voltage output terminal including a high resistor just before the atomization position to supply the high voltage. The external electrode itself can be thereby formed near the spray gun and to a small size, and the electrostatic coating spray gun which is highly safe and is excellent in electrostatic coating effect and operability can be obtained.

    Abstract: PROBLEM TO BE SOLVED: To sufficiently exhibit electrostatic coating effect even in the case of a low voltage as a spray gun for electrostatic coating which uses coating having a low resistance value.
    SOLUTION: The spray gun for the electrostatic coating enables the coating flowed out and aired from a coating jetting nozzle to be a ground potential and arranges an electrode outside a coating spray area. An atomized air jetting port is arranged at a coating jetting port and its surrounding as an atomizing means. A nozzle (LV nozzle) for allowing the coating and air to collide with each other with directional components where the direction of the jetting of the coating and the direction of the jetting of central air cross each other and spraying them is used. A taper surface where the coating jetting port is expandably opened is formed, and a plurality of V-shaped grooves are notched toward the center of the jetting port in the outer peripheral face of the jetting port placed in the central hole of a cap.
