Engage. As a result, power is supplied from the power supply to the work via the current collector, and the work is started to be immersed in the electrodeposition tank and at the same time, the electrodeposition process is started. At this time, the coating film sequentially formed on the work by the electrodeposition action acts as an electrical insulator. For this reason, the paint slowly adheres to the work part on which the coating film has already been formed, and the paint rapidly adheres to the work part subsequently immersed in the electrodeposition tank, so that the thickness of the coating film becomes uniform.

Further, even when the work is pulled up from the electrodeposition tank after the lapse of a predetermined time, the electrodeposition process is continued until the whole work goes out of the electrodeposition tank. In this way, since the electrodeposition processing is performed during the work lowering time and the work rising time, it is possible to shorten the electrodeposition coating work time while ensuring a sufficient electrodeposition processing time. As a result, it is possible to improve productivity while maintaining the advantages of the batch type electrodeposition coating apparatus.

Further, since the current collectors (31a, 31b) and the power feeders (41a, 41b) are engaged with each other with a constant contact pressure by the biasing means 61,
Power is reliably supplied to the work 9 and the electrodeposition process is performed without any trouble. Furthermore, since the electrodeposition coating film sequentially formed from the lower end portion to the upper end portion of the work 9 by the electrodeposition work acts as an electrodeposition insulator, the work piece on which the coating film has already been formed is slowly coated with the paint. As a result, the coating material quickly adheres to the portion of the work 9 that is successively immersed in the electrodeposition tank 1, so that the thickness of the coating film becomes uniform. Subsequently, the electrodeposition process is performed for a predetermined time while the work 9 is completely immersed in the electrodeposition tank 1.

In this way, since the work descent / work rise and the electrodeposition process are performed at the same time, it is possible to shorten the electrodeposition coating work time while ensuring a sufficient electrodeposition process time. For example, when the work 9 needs to be electrodeposited for 3 minutes, if the electrodeposition treatment is performed during the raising / lowering time of the work 9 (each 1 minute in this embodiment),
It is sufficient to perform the electrodeposition treatment for about 1 minute while the work 9 is completely immersed in the electrodeposition tank 1. Even if it takes 30 seconds each to position and carry out the work 9, the electrodeposition coating work time is about 4 minutes. can do. Therefore, the working time can be shortened by about 2 minutes as compared with the conventional batch type electrodeposition coating apparatus in which the electrodeposition treatment is performed only in a state where the work 9 is completely immersed in the electrodeposition tank 1.
