Abstract: A highly-viscous material coating apparatus for use, e.g. in an automobile coating process, to coat a joint of a workpiece, may be mounted on a robot. It provides improved operation where the workpiece provides a reference surface parallel to the joint, where the workpiece provides a reference surface displaced from the joint at varying distances along the length of the joint, and where the workpiece provides no reference surface. Where a reference surface is available, an extendable spring-biased guide pin of the apparatus moves along the reference surface, and any positional errors are compensated-for by action of the spring. If the distance between the reference surface and the joint varies, the varying distance may be compensated for by various disclosed practices. The apparatus also can be used where no reference surface is provided by retracting the guide pin with respect to the nozzle and by controlling the robot so as to direct the nozzle to the joint.

The inner periphery of the tip portion is formed as a conical face which diverges toward the outside of the spray head. A plurality of paint guide grooves are formed on only the inner periphery of the conical face.

Abstract: A drying furnace for use in coating drying in which a hot gas recycling duct for emitting radiation heat is disposed on the inlet zone of a tunnel-like furnace main body and resin-removing ducts are disposed along the ceiling of the inlet zone and the exit zone of the furnace main body respectively, wherein the furnace main body is turned in a U-shaped configuration so that the inlet and the exit thereof are arranged side by side, and the hot gas supplied to the hot gas recycling duct is supplied to each of resin-removing the ducts. Resinous substances can surely be prevented from forming and depositing at both of the inlet and the exit of the furnace and the cleaning work for the resin-removing ducts can be saved.

Abstract: A method of operating an air-supplied type coating booth in which conditioned air supplied from an air supply blower is enforced downwardly to the inside of a tunnel-shaped coating booth and the air in the coating booth is drawn together with paint mists and the likes down to the beneath of a booth floor by way of an air exhaust blower comprises the steps of detecting the flow velocity of air streams flowing into or out of inlet and the exit of the coating booth, applying primary and secondary averaging processings for signals for averaging variations caused by external disturbances fluctuating at relatively shorter and longer periods of time, judging the thus averaged direction and the flow velocity of the air streams at the inlet and the exit, variably controlling the flow rate of exhaust from the exhaust blower in accordance with the direction and the flow velocity.

Abstract: A method of operating an air-supplied type coating booth in which conditioned air is enforced from an air supply blower downwardly to the inside of a coating booth and then discharged to the beneath of the booth floor by an exhaust blower, in which the booth operation is stopped after memorizing the balanced flow rates for the supply blower and the exhaust blowers kept just before the completion of the booth operation, and the supply blower and the exhaust blower are automatically set to the above-mentioned balanced flow rates respectively upon re-starting the booth operation again. Balanced and stable booth operation where no air streams flow into or out of the inlet and the exit can be attained rapidly at the start of the booth operation.

Abstract: A method of operating an air-supplied type coating booth adapted to enforce conditioned air by an air supply blower through a filter downwardly to the inside of a tunnel-shaped coating booth at a predetermined flow velocity and then drawn to discharge together with coating mists, etc. to the beneath of the floor comprises the step of detecting the flow velocity of conditioned air flowing through the filter to the inside of continuously, applying primary and secondary averaging processings for the detected signals containing variations fluctuating at relatively shorter and longer periods respectively, comparing the value obtained from the signals applied with the secondary averaging processing with a predetermined flow velocity value and variably controlling the flow rate of the air supplied from the air supply blower depending on the deviation and thereby maintaining the flow velocity of the conditioned air flowing to the inside of the coating booth always constant.
