Immerse in liquid tank b. When the storage casing 22 is immersed for a predetermined period of time due to the stop of the hanger 16 rising and lowering, the hanger 16 rises, and in the raised position, the mounting piece 35 of the support body 28 is placed on the support piece 18 and locked. Projection piece 34 and hanging piece 4
0 and the support 28 is advanced by the hanger 16. The second invention is a pair of hanging pieces 40 of the first invention,
An embodiment in which a pair of endless feeding devices 42, 42 are provided over a long liquid tank b' which does not require an anode pole in place of the anode pole 40 will be described with reference to FIGS. 3 and 4.

The endless feeding devices 42, 42 move the liquid from the top of the main body frame 1 to the liquid tank b'.
Chain gears 43, 43' are attached to the front and rear ends of a pair of left and right mounting rods 41, 41 hanging vertically above the chain gears 43, 43.
The chain gear 43 is connected to the upper and lower chains 10 of the carrier 12, and
Chain gears 9 provided above and below the main body frame 1 that run intermittently through 10'
, 9' and the transmission mechanism 46, the endless chain 44 is synchronized with the chains 10, 10' and runs at the same speed.

The endless feeding devices 42, 42 face each other in the left-right direction directly above the liquid tank b', and are spaced apart from each other in the left-right direction so that the locking protrusion 34 of the support body 28 can be mounted thereon. Furthermore, the chain 4
The running upper part 45 of No. 4 is positioned directly below the locking protrusion 34 when the support body 28 is in the uppermost position by the hanger 16. An endless belt may be used instead of the endless chain 44. The rail T of the elevating pedestal 6 is removed except for the foremost stop position X of the long liquid tank b', and the elevating pedestal 6, which repeats the basic elevating operation, allows the storage case 22 to rise from the intermediate stopping position from the liquid tank b. Prevent this from happening.

The operation of the above embodiment will be explained. Support body 28 and storage case 2
When the hanger 16 on which the anode electrode rod 2 is placed moves forward in the raised position onto the long liquid tank b' where no anode pole is required, the feeding devices 42, 42 are disposed above the liquid tank b', so that the hanger 16 moves to its stopping position. l
The locking protrusion 34 of the support body 28 is arranged directly above the running upper part 45.

Therefore, when the hanger 16 descends along with the elevating frame 6, the support body 28 on which the anode pole rod 26 is suspended is suspended from the running upper part 45, and only the storage case 22 descends together with the hanger 16, causing the liquid tank b' immersed in the initial position I of. Storage case 2
When the predetermined stopping time of 2 at the initial position I expires, the elevating frame 6 rises, but since the rail T is cut off and does not engage with the engagement roller 15, the storage case 22 does not rise.

Therefore, when the carrier 12 moves forward in the next process, the storage case 2
2 is transferred to the position while being immersed in the liquid tank b'. At this time, the chain 44 of the feeder 42 is connected to the chain 1 of the carrier 12.
0 and 10', the support body 28 suspended from the traveling upper part 45 stops right above the position as the storage case 22 moves. The storage case 22 and the support body 28 are separated into upper and lower positions and repeatedly move intermittently to a predetermined stop position until they reach the frontmost stop position 15 is placed thereon, the storage case 22 rises and is taken out from the liquid tank b'.

When the hanger 16 rises, a support 28 is placed directly above the position
is suspended from the traveling upper part 45, so the hanger 16 is again
The support body 28 is transferred thereon, and the anode pole rod 26 passes into the object to be processed a in the storage case 22. As described in detail above, the first aspect of the present invention is that the hanger 16
A pair of hanging pieces 40, 40 are provided on the liquid tank b where the anode pole is not needed, and the support body 28 on which the anode pole rod 26 is vertically disposed is suspended. When the hanger 16 is lowered above b, the support body 28 is suspended by the pair of hanging pieces 40, 40, and only the storage case 22 is immersed, thereby preventing the anode pole rod 26 from being immersed in the processing liquid tank b. be able to.

In addition, the second invention is a long liquid tank b'1. in which the support body 28 does not require an anode pole. Endless feeding devices 42, 42 provided over
Since the hanger 16 suspending the storage case 22 is raised at each stop position of the liquid tank b', the support body 28 is moved forward at the same speed as the carrier 12. Since there is no need to apply the liquid using the hanger 16, the hanger 16 is moved to the lower position and stored in the liquid tank b'.
It is possible to carry out intermittent transfer while immersing the object 2, which has an excellent effect of lengthening the immersion time of the object a.
