It is supposed to. Horizontal moving means for moving the frame equipped with the hoist,
It can be stopped at a predetermined position by the position control means, and is moved to a predetermined position above the electrolytic cell 58 by the position control means.

[0004]

In the conventional electrode plate transport device, the suspension frame 50 is suspended by the wire-W as described above. Therefore, after the suspension frame 50 stops the horizontal movement,
In some cases, the swing of the suspension frame 50 is transmitted to the electrode plate 56, and an error occurs in the stop position of the horizontal moving unit. For this reason, when the suspension frame 50 is lowered, the electrode plate 56 is brought into contact with the edge of the electrolytic cell 58, and a plurality of shaking electrode plates 56 hit each other to damage or dent the electrode surface. was there. Also, if the electrode plates 56 are arranged while shaking, the arrangement intervals of the electrode plates 56 are not constant, so that when the hooks 52, 54 are inserted between the electrode plates 56 and hung, the hooks 52, 54 There are drawbacks such that they cannot be inserted because they hit the plate 56, and the hooks 52 and 54 damage the electrode plate 56.

6a is pressed against the anode-side electrode plate 56b and the hook 5
There was a space to insert 2,54. FIG. 6 (b)
In the example shown in FIG. 2, when the thickness of the ear portion of the anode-side electrode plate 56b is the standard 24 mm, the cathode-side electrode plate 56a and the anode-side electrode plate 5
6b may be smaller than the ears, in which case the worker had to go there and correct it manually. Thus, in the prior art, the electrode plate 56
The work for correcting the gap between them and the hooks 52 and 54
6 or the correction work for placing the electrode plate 56 has to be performed manually, which has a disadvantage that the working efficiency is poor.

There was a drawback that the electrode plate 56 could not be correctly placed on the conveyor due to an error in the stop position of the means.

The present invention has been made in view of the above-mentioned problems of the prior art,
A plurality of electrode plates can be inserted into or removed from a predetermined position of the electrolytic cell at a fixed interval with high accuracy, whereby the intervals between the electrode plates 56 that have been manually adjusted can be reduced from hooks arranged at equal pitches. Improve the work efficiency at the time of lifting and lowering the electrode plate by allowing it to be accurately lowered as it is, and at the same time,
It is an object of the present invention to provide an electrode plate transport device capable of manufacturing a high quality metal plate without scratches and dents.

Similarly, the same number of anode hooks F2 for hooking the side electrodes are provided. Cathode hook F1
The vertical movement with respect to the hanging device 16 and the horizontal movement of the hanging device 16 in the longitudinal direction are possible by means of the lifting / lowering means and the horizontal moving means in the hanging device 16 which are not shown.
The lower end of the cathode hook F1 and the anode hook F2 is bent in a key shape so as to hang the electrode plate 22, and is rotated by a turning mechanism (not shown) provided in the suspension device 16. And the lower end of the key shape can be hung on the electrode plate 22.

A pair of guide rods 18 are provided near the two longitudinal ends of the suspension device 16, respectively.
2, so that it can be slid vertically.
As shown in FIGS. 2 and 3, four brackets are provided on the upper side and four brackets are provided on the lower side in the bracket 12 a fixed to the suspension device 16.
The upper roller 12b and the lower roller 12c are incorporated. Each of the upper roller 12b and the lower roller 12c is arranged so that the rotation axis is directed horizontally, and therefore, the rolling surfaces are opposed to each other. The upper roller bearing 12d and the lower roller -It is rotatably supported by the bearing 12e and attached to the bracket 12a. The mechanism of the slide bearing 12 and the guide rod 18 can be replaced with a linear motion guide mechanism including a linear guide and a guide rail.

As shown in FIG. 4, the guide rod 18
A stopper 24 having a convex portion 24a for preventing the guide rod 18 from falling off the slide bearing 12 is provided at the upper end of the slide bearing 12. The stopper 24 is fixed to the guide rod 18 by fastening the nut 26b with a bolt 26a through the through hole 26. Guide rod 1

Are formed, and a convex member 3 on the electrolytic cell 30 side described later is formed.
2 and the convex rail 42 on the conveyor 40 side. A cylindrical relief hole 18c is formed at the top of the inner surface of the concave portion 18a so that when fitted to the convex member 32, small foreign matter or the like is released to prevent rattling. Since the conical concave portion 18a and the convex member 32 are in contact with each other over the entire conical surface, positioning can be performed easily and accurately. The shape of the concave portion 18a can be various shapes in relation to the convex member 32. For example, the positioning between the guide rod 18 and the convex member 32 can be performed even if the concave portion 18a has a cylindrical shape. The guide rod 18 is made of chrome-plated carbon steel to prevent corrosion and wear.

Next, a large number of electrolytic cells 30 are arranged adjacent to each other.
Will be described.

The electrolytic tank 30 is a tank for storing an electrolytic solution such as dilute sulfuric acid, and is placed on the floor without looseness by legs 34 provided on the bottom surface. In the illustrated embodiment, a plurality of electrolytic cells 30 are drawn continuously only in the horizontal direction.
Of course, a plurality of rows can be arranged in the vertical direction.

In each of the electrolytic cells 30, an electrode plate transfer device 10 is provided.
A large number of electrode plates 22 suspended by are arranged.
The electrode plate 22 has an anode electrode and a cathode.
There are two types of electrode on the cathode side, and a large number of these two types of electrode plates are alternately arranged in the same electrolytic cell 30 at regular intervals. A pair of opposing side plates 30 forming side surfaces of the electrolytic cell 30
a, 30b are provided on the upper edges of the projecting members 32a,
32b is fixed. In addition, two convex members 32 are arranged in each electrolytic cell 30, and are configured such that the axis of the guide rod 18 coincides with that of the guide rod 18 when the suspension device 16 is lowered.

As shown in FIG. 5, the convex member 32 has a conical shape such that its upper portion is fitted into the concave portion 18a of the guide rod 18. The material of the convex member 32 is a stainless steel material. In the present embodiment, the convex member 3
2 is formed in a conical shape, but may be formed in a hemispherical shape. In this case, the concave portion 18a on the guide rod 18 side may be formed in a hemispherical shape.

Next, the structure of the conveyor 40 will be described.

As shown in FIG. 1, the conveyor 4 supplies or receives the electrode plates 22 to or from the suspension device 16.
On the floor adjacent to 0, a convex rail 42 is installed in parallel with the longitudinal direction of the suspension device 16. This convex rail 4
5, the cross-sectional shape is formed in an inverted V-shape following the groove 18b of the guide rod 18 as well shown in FIG. To be fitted. In addition, the conveyor 40
Any structure may be used as long as it can support a large number of electrode plates 22 on the upper surface at predetermined intervals.
Although not shown, guide means for aligning both side edges of the large number of electrode plates 22 are provided.

Next, the operation and effect of this embodiment will be described.

Since the present embodiment is configured as described above, after the frame is horizontally moved to a desired electrolytic cell 30 out of a plurality of electrolytic cells 30 arranged in parallel,
The hoist is operated to extend the wire-W and lower the suspension device 16. As a result, first, the concave portion 18a of the guide rod 18 starts to fit into the selected convex member 32 of the electrolytic cell 30. At this time, since both the concave portion 18a and the convex member 32 have a conical shape, even if the guide rod 18 is inserted with a slight displacement in the horizontal direction with respect to the axis of the convex member 32, the guide rod 18 follows the descent of the guide rod 18. It is corrected on the center line of the convex member 32. Even if small foreign matter adheres to the top of the convex member 32, the small foreign matter escapes to the escape hole 18c, so that the guide rod 18 does not rattle.

As described above, since the suspension device 16 can be accurately lowered with respect to the electrolytic cell 30, the plurality of electrode plates 22 can be stably inserted at a constant interval into the electrolytic cell 30. Further, since the electrodes can be accurately arranged at regular intervals in the electrolytic cell 30, the current efficiency between the electrode plates 22 can be improved. In the present embodiment, it can be expected that the current efficiency is improved by 1% or more.

As described above, the guide rod 18 is supported by four upper and lower rollers 12b and four lower rollers 12c in the upper and lower portions of the slide bearing 12, respectively. Since the portion is slidable, the guide rod 18 can be retracted from the lower surface of the suspension device 16 at the time of maintenance, and the suspension device 16 can be placed at a predetermined place.

Further, the electrode plate transport device 10
In the conveyor 40 for supplying or receiving the same, the groove 18b at the lower end of the guide rod 18 is fitted with the convex rail 42, and the guide rod 18 slides to move the suspension device 16 to a desired position with respect to the conveyor 40. Guide accurately. For this reason, like the operation on the electrolytic cell 30 side, the electrode plate 22
Can stably and reliably perform the supply / reception operation, thereby improving the work efficiency. Note that the convex member 32 is used instead of the convex rail 42.
The same effect can be obtained by arranging the same convex member adjacent to the conveyor 40.

[0029]

Since the present invention is configured as described above, it has the following effects.

In the electrode plate transport device of the present invention, when the entire suspension device descends from above a predetermined position of the electrolytic cell, first,
The positioning means starts the engagement between the lower end surface of the guide rod and the upper end surface of the engaging member. In the early stage of engagement of both,
Since the horizontal displacement of the guide rod is allowed and the horizontal displacement of the guide rod is corrected at the final stage of engagement to precisely position the guide rods, the stop positions of the suspension device above the electrolytic cell are compared. Ultimately, even if it is loose, the guide rod and the engaging member are precisely positioned, so that a large number of electrode plates suspended by the suspension device are inserted into the electrolytic cell with precise position control. can do.

In addition, the work of correcting the gap between the electrode plates or manually attaching the hooks to the electrode plates is reduced,
Work efficiency can be improved.

Further, since the electrode plates are stably moved up and down, the plurality of electrode plates do not shake and collide with each other, so that scratches and dents are not made on the electrode surfaces. Further, when the hook is inserted between the electrode plates, the electrode plates are not damaged. Thus, it is possible to manufacture a high-quality deposited metal plate having no scratches or dents on the surface.

Further, since the electrode plates can be accurately arranged at a constant interval and at a narrow interval in the electrolytic cell, the current efficiency between the electrode plates is improved. As a result, the power consumption of the equipment can be reduced.
