And the electrode plate conveyance apparatus 10 is moved, it stops at the predetermined position above the electrolytic cell 30, and the cathode hook F1 is lowered. At this time, since the recessed part Ab is formed in the upper part of the anode plate A, the lower end part of the cathode hook F1 does not contact the upper end part of the anode plate A.

When the cathode hook F1 is lowered to a position slightly lower than the conductor bar Ka, the rod R is rotated 90 degrees to allow the forked portion 5 to enter the window Kb. As a result, as shown in Fig. 7A, the cathode plate K is supported by the forked portions 5 and 5 of adjacent hooks. At this time, since the inclination is formed on the upper surfaces of the forked portions 5 and 5, the conductor bar Ka is equally supported by the forked portions 5 and 5 of the cathode hooks F1 and F1 adjacent to the inclined portions. It moves itself to the position where it reaches, and reaches the right position.

And as shown in FIG.9 (b), the cathode hook F1 is raised and conveyed to a predetermined position in the state which suspended the cathode plate K. As shown to FIG. At this time, the mechanism for raising the cathode hook F1 is based on the mechanism by which the aforementioned winding device 41 suspends the cathode upper frame 20.

The same operation is also carried out by suspending the cathode plate after the electrodeposited metal has been peeled off and taking it out of the conveyor 40. However, by inclining the cathode plate K by the inclination formed on the upper surfaces of the forked portions 5 and 5. Since the conductor bar Ka naturally shifts and moves to the right position, and the cathode plates K are arranged at equal intervals, positioning of the electrode plates by manual operation when the cathode plates K are immersed in the electrolytic cell 30 again. There is no need to work.

Next, the operation in the case of charging the cathode plate K to the conveyor 40 will be described.

And the conductor bar Ka is charged to the support part 43 provided on the rail 41 of both sides of the conveyor 40. As shown in FIG. Since the angle θ formed between the inclined surface of the support portion 43 and the vertical direction is the same as the inclination angle θ of the upper surface of the forked portion 5, the support portion 43 can be inserted into the support portion 43 smoothly.

Then, the rod R is rotated 90 degrees so that the forked portion 5 is parallel to the conductor bar Ka while the hooks F1 and F1 for the cathode are slightly lowered, and the forked portion 5 is the window portion Kb. Move out from By this. The cathode plate K is conveyed to the peeling apparatus which is not shown in the next process.
