A is a suspension device for transporting an electrode plate, 1 is a frame body for suspending an electrode plate constituting the suspension device A, and a suspension device A for transporting an electrode plate including the frame body.
Is an electrode plate transport chain conveyor 2 for electrode plate storage
When the electrode plate is carried in and out of the chain conveyor 2, it is carried above the chain conveyor 2 by an overhead crane (not shown), and vertically between the chain conveyor 2 and the chain conveyor 2 by the overhead crane. It is designed to be lifted up and down. The chain conveyor 2 is arranged at such a position that the electrode plate received from the suspension device A and placed on the upper part thereof is conveyed to an electrode plate stripping machine (not shown). Reference numeral 3 denotes a main body of the frame body 1, which is formed in a rectangular shape in a plan view, and has the same orientation as the electrode plates 4 (cathode plates are illustrated in the drawings) mounted on the conveyor 2 on both sides of the main body. The overhanging piece 5 is fixed. Guide rollers 6 as guide members are provided on both end portions of the overhanging piece 5 so as to be rotatable outward at a predetermined angle θ. Although various angles are conceivable as the mounting angle θ of the guide roller 6, 45 ° as shown in the figure is particularly preferable because the engagement with the guide frame described later can be performed smoothly and reliably. In this example, the guide roller 6 is mounted by a pin 8 between a pair of mounting pieces 7 fixed to the lower surfaces of both end portions of the overhanging piece 5 as shown in FIG.

Reference numeral 10 is a hanging fitting for an overhead crane, which is a main body 3
A pair of upper frames installed on the upper surface of the frame at a predetermined interval
11 is provided on. An electrode plate (cathode plate) hook 13 is mounted on the frame body 1 so as to be rotatable about 90 ° at a position in the same direction as the direction of the electrode plate 4 and at a position substantially orthogonal to the position. An actuating cylinder 16 for rotating the slide shaft 14, the arm 15 and the like is installed, and the electrode plate 4 can be suspended as the electrode plate transport suspension device A is moved up and down. Since the configuration and operation of are almost the same as the conventional ones, detailed description thereof will be omitted.

Reference numeral 20 denotes a guide frame which engages with the guide rollers 6 and guides the elevating and lowering of the frame body 1. The guide frames 20 are provided around the chain conveyor 2 in a number corresponding to the guide rollers 6 (four in this embodiment). It is mounted on the mounting frame 21. In FIG. 3, 22 is a connecting member that connects the upper ends of the mounting frames 21. The lower end of the mounting frame 21 is the base frame
It is fixed at 23. These guide frames 20 are shown in FIG.
As shown in (A) and (B), the guide roller 6 is formed so as to be bent so that its cross section becomes substantially L-shaped, and the bent inner surface corner portion 25 is engaged with the guide roller 6. Further, the upper end portion of the guide frame 20 is formed into an expanding portion 26 which is tapered outwardly and upwardly, and the suspension device A for electrode plate transfer which swings back and forth and left and right above the chain conveyor 2 is provided. Even if the guide frame 20 is slightly displaced from the position of the guide frame 20 when it descends, it can be received by the expansion portion 26 and the guide roller 6 can be reliably engaged with the corner portion 25 of the guide frame 20.

In the apparatus of this embodiment, the suspension device A for transporting the electrode plate is suspended by an overhead crane via suspension metal fittings 10 provided on the frame 1, and the suspension device A is suspended. The electrode plate 4 suspended by the hooks 13 provided on the frame body 1 of the plate transport suspension device A is attached to the chain conveyor 2
In the case of temporarily placing it on the upper side, the suspension device A for transporting the electrode plate is lowered at a predetermined position above the chain conveyor 2. Then, as shown in FIG. 3, when the electrode plate 4 is placed on the upper portion of the chain conveyor 2, the hook 16 is pivoted about 90 ° by the cylinder 16 to remove the hook 13 from the electrode plate 4.
After that, the suspension device A for transporting the electrode plate is lifted again by the overhead crane, and is moved up to the electrolytic cell where the electrolytic cell is located so as to suspend the next electrode plate 4.

When the suspension device A for transporting the electrode plate is moved up and down, the four guide rollers 6 provided on the sides of the frame 1 of the suspension device engage with the inner corners 25 of the guide frame 20, respectively. The suspension device A for transporting the electrode plate is smoothly moved up and down along with it without rocking. Further, at this time, even if the suspension device A for transporting the electrode plate before engaging with the inner surface corner portion 25 of the guide frame 20 swings back and forth and left and right to some extent, the guide roller 6 causes the expansion portion 26 of the guide frame 20 to expand. It will be received by and will be reliably brought to the inner surface corner portion 25. In the above operation, various sensors are provided to detect the completion of lifting of the electrode plate, the detection of the lifting of the electrode plate, the detection of the landing on the frame, the detection of the electrode plate full, the detection of the electrode plate loading, etc. Since these devices are known, detailed description thereof will be omitted.

[0012] As described above, the guide frame 20 and the guide roller 6 guide the suspension A for transporting the electrode plate, which is moved up and down, so that the suspension A for transporting the electrode plate can be mounted on the chain conveyor 2. Can be stopped in place.

Although the guide roller 6 is used as the guide member in the embodiment, the guide roller 6 is a preferable example of the guide member and is not necessarily a guide roller. It can be anything. Further, four guide rollers 6 are provided at the four corners of the frame body 1,
Moreover, four guide frames 20 are also installed, but it is sufficient that at least two guide frames 20 are provided in the diagonal direction. Further, although the electrode plate transporting chain conveyor 2 is shown as an example of the electrode plate storage space, this is not necessarily the electrode plate transporting chain conveyor 2 and may be an electrolytic cell.
In the case where the electrolytic cell is used as an electrode plate yard, when the suspension device A for transporting the electrode plate is stopped at a predetermined position of the electrolytic cell and the electrode plate 2 is replaced, an overhead crane operator by a slinger as in the conventional case is used. There is no need for any manual work such as a signal for positioning the suspension device A for transporting the electrode plate to and a fine adjustment of the position of the electrode plate when the electrode plate is carried in and out. Further, although the electrode plate frame 1 for the cathode plate is shown in the embodiment, this is also an example,
It may be used for the anode plate, or may be also used as the bipolar plate as in the prior art.

[0014]

Since the inventions of claims 1 and 2 are configured as described above, the positions of the suspension device and the electrode plate by the manual work at the time of loading and unloading the electrode plate by the sling person, which have been conventionally required. The fine adjustment work of is not necessary, and the replacement work of the electrode plate can be automated. In addition, accidents such as electrode plate fallout can be prevented, safety is enhanced, and reliability with respect to the electrode plate transport suspension device is dramatically improved. According to the invention of claim 3, in addition to the above effect, since the guide member is adapted to engage with the inner surface corner portion of the guide frame, the engagement is ensured.
