Therefore, the hanger 16 descends with the elevating frame B. Then, the support col 1 having the 7-node pole rod 26 hanging thereon is suspended from the running upper part us, and only the 2 housings are lowered together with the hanger 16 and immersed in the initial position (J) of the liquid tank b'.

When the predetermined stopping time of the storage case λλ at the initial position (1) expires, the elevating frame 6 rises, but since the rail 7 is cut out and does not engage with the engagement roller IS, the storage case 22 does not rise. Therefore, when the carrier 12 moves forward in the next step, the two storage cases are transferred to the position while being immersed in the liquid tank b'. At this time, since the feeding device-cheno 1 runs in synchronization with the chino 1oSio' of the carrier 12,
The support body 2r'l suspended from the traveling upper part tts moves and stops directly above the position (table) as the storage case 2 moves.

The storage case 1 and the support body 1 repeatedly move intermittently to a predetermined stop position while being separated into upper and lower positions, until they reach the frontmost stop position (X), and at that position, the hanger / Since the fourth engaging roller IS is placed thereon, the storage case 22 rises and is taken out from the liquid tank b'. When the hanger 16 rises, the support 21 is suspended from the running upper part g5 directly above the position (X), so the support xi is transferred onto the hanger 16 again, and the anode fence rod roller is placed in the storage case λ2 to be processed.
