Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode plate transport apparatus for supplying and discharging a large number of electrode plates to and from an electrolytic cell for electrolytic refining or collection of non-ferrous metals such as copper and lead. Equipped with a crane suspension frame, which is transported by a crane device and horizontally moves the crane suspension frame above the electrolytic cell, and lifts and lowers the crane suspension frame at that position to mount the electrode plate at a predetermined position in the electrolytic cell. The present invention relates to an electrode plate transport device for inserting or extracting an electrode plate from an electrolytic cell.

[0002]

2. Description of the Related Art The present applicant has disclosed in Japanese Patent Application Laid-Open No. 9-2499.
No. 85 has proposed an electrode plate transport device. This electrode plate transport device will be briefly described with reference to FIG.

That is, the electrode plate transporting apparatus 1 of this embodiment has a crane suspension frame 2 provided with hooks 2a for suspending a large number of electrode plates P. The crane suspension frame 2 is suspended by a wire W on a self-propelled crane device (not shown) disposed above the crane suspension frame 2. The crane device can move the electrode plate transport device 1 to an arbitrary position of an electrolytic cell of the plurality of electrolytic cells 100 arranged in parallel.

[0004] The electrode plate transporting device 1 transported to a predetermined electrolytic cell position lowers or raises the crane suspension frame 2 by driving a hoisting device attached to the crane device, and moves the electrode plate P to the electrolytic cell 100. It is charged inside or withdrawn from the electrolytic cell 100.

[0005] Since the position of the electrode plate P in the electrolytic cell 100 cannot be kept constant only by the movement control of the crane device, it is necessary to readjust the electrode plate 100 manually.

Therefore, the electrode plate transport device 1 stops the swing of the crane suspension frame 2 caused by the movement by the crane device,
It prevents damage caused by collision between the electrode plate P and the electrolytic cell 100 that occurs when the electrode plate P is inserted into the electrolytic cell, and further positions the crane suspension frame 2 with higher precision with respect to the electrolytic cell 100. For this purpose, a positioning guide 10 is provided. When the electrode plate transport device 1 is transported to a predetermined electrolytic cell 100 position, the positioning guide 10
The crane suspension frame 2 is fitted to a positioning pin 101 provided for the crane suspension frame 00 to prevent swinging and position.

That is, a positioning guide 10 is provided in the electrode transfer device 1 via slide bearings 3 attached to both longitudinal ends of the crane suspension frame 2. The positioning guide 10 includes an elongated rod-shaped pin guide 11 and a positioning member 12 provided at a lower end of the pin guide 11. At the upper end of the pin guide 11, a stopper 13 is provided so that the pin guide 11 does not fall off the slide bearing 3, and at the lower end of the positioning member 12, a conical recess 14 is formed as shown in FIG. ing.

On the other hand, as shown in FIGS. 7 and 8, a convex positioning pin 101 is disposed on the upper surface of the side wall of the electrolytic cell 100, and when the crane suspension frame 2 descends, the positioning member 12 The concave portion 14 is fitted to the convex positioning pin 101.

With this configuration, the electrode plate transport device 1
The swing of the crane suspension frame 2 can be stopped, and the crane suspension frame 2 can be positioned with higher precision with respect to the electrolytic cell 100. In this state, the electrode plate can be inserted into the electrolytic cell. Alternatively, since the electrode plate can be extracted from the electrolytic cell, the adjustment of the electrode plate arrangement in the electrolytic cell by the manual operation of the operator becomes easy, and in some cases, it becomes unnecessary.

[0010]

However, the present inventors have actually manufactured the electrode plate transport device 1 having the above-described configuration and used it for transporting and replacing the electrode plates P.
The positioning guide 10 is suspended by its own weight from the crane suspension frame 2 in a state where the stopper 13 is in contact with the slide bearing 3. Therefore, the crane device is configured such that the lower end portion of the positioning guide 10 has the electrolytic cell 100 or other It was essential that the crane suspension frame 2 be moved to a position high enough to avoid collision with the equipment while being lifted.

Therefore, conventionally, the positioning member 12 of the positioning guide 10 can be inserted into the positioning pin only at a fixed height of the crane suspension frame 2. This means that there are various problems in actually using the electrode plate transport device 1, for example, in a place other than the electrolytic cell,
Even when 01 is not used, there arises a problem that the crane suspension frame 2 must be moved while being kept high.

Further, in the electrode plate transporting apparatus 1 having the above configuration,
If the crane suspension frame 2 is finely adjusted vertically when the electrode plate P is inserted into the electrolytic cell 100, the positioning member 12 of the positioning guide 10 comes off the positioning pin 101 on the electrolytic cell, so that fine adjustment cannot be performed. A problem arose.

Accordingly, it is an object of the present invention to allow the crane suspension frame to be moved at any height, whereby
It is an object of the present invention to provide an extremely convenient electrode plate transporting device that can insert a positioning guide into a positioning pin at an arbitrary height.

Another object of the present invention is that the positioning guide does not come off from the positioning pins, and the crane suspension frame can be finely adjusted vertically when the electrode plate is inserted into the electrolytic cell. An object of the present invention is to provide a convenient electrode plate transport device.

[0015]

The above object is achieved by an electrode plate transport apparatus according to the present invention. In summary, the present invention comprises a crane suspension frame capable of suspending a large number of electrode plates, and a positioning guide supported on the crane suspension frame via bearing means so as to be able to move up and down. In an electrode plate transfer device that is conveyed and positioned above the electrolytic cell, a gear device for moving the positioning guide up and down, a drive motor for driving the gear device, and the gear device One-way torque transmitting means for transmitting only one-way torque from the drive motor,
It is an electrode plate conveyance device characterized by having.

According to one embodiment of the present invention, the gear device includes a rack member formed with a rack gear disposed on the positioning guide, a pinion gear device including a pinion gear meshing with the rack gear, Having.

According to another embodiment of the present invention, the one-way rotational force transmitting means includes a driven member integrally connected to a pinion gear of the gear device, and a rotational force from the drive motor. And a drive member for transmitting to the member. Preferably, the driven member is a ratchet gear, and the driving member is a claw member that releasably meshes with the ratchet gear.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an electrode plate conveying apparatus according to the present invention.

The overall configuration of the electrode transport device 1 of the present invention is the same as that of the conventional electrode transport device 1 shown in FIG. 7 described above, and differs mainly in the configuration in which the positioning guide 10 is driven by a motor. The members having the same configuration and function are denoted by the same reference numerals, and the detailed description thereof will be omitted. The configuration of the motor-driven positioning guide 10, which characterizes the present invention, will now be described in detail.

cm, an elongate pipe having an upper end sealed with a plug cover 15 and a positioning member 12 attached to a lower end.
The positioning member 12 has a concave portion 14 that opens downward in a conical shape at the lower end thereof, and an inverted V-shaped groove 16 that extends in a direction perpendicular to the axis at the distal end of the concave portion. The concave portion 14 can be fitted to a conical convex member (positioning pin) 101 provided on the electrolytic cell 100 side and having a complementary shape to the concave portion 14.

According to this embodiment, the pin guide 11 has
Further, a rack member 18 having a rack gear 17 formed over a predetermined length along the longitudinal axis thereof is integrally attached. According to the present embodiment, the rack member 18 has a length L from a position L2 = 3 cm below the upper end of the pin guide.
3 = 167 cm.

On the other hand, a drive device 20 for meshing with the rack gear 17 of the rack member 18 and driving the positioning guide 10 is arranged on the frame 31.

Referring particularly to FIG. 4, according to the present embodiment, the drive device 20 includes an electric motor 21 and a speed reducer 22 as a drive source. Output shaft 2 from reduction gear 22
3 extends in the horizontal direction, and its tip is
Is carried by the bearing 24 installed in the first position. The output shaft 23 includes a pinion gear device 26 having a pinion gear 25 meshing with the rack gear 17, and a latch device 40 as a one-way torque transmitting means for transmitting only one-way torque to the pinion gear 26. Is arranged.

First, the latch device 40 will be described.

The output shaft 23 is provided with a flange 41 integrally forming a driving member at a position adjacent to the speed reducer 22.
A sleeve 42 is rotatably disposed coaxially between the flange 41 and the bearing 24 on the outer periphery of the output shaft 23.

One end of the sleeve 42, that is, the flange 41
A ratchet gear 44 as a driven member is integrally attached to the end on the side facing the boss by a bolt 43. or,
The flange 41 meshes with the ratchet gear 44,
A pawl member 45 for transmitting a one-way rotational force to the ratchet gear 44 is swingably disposed via a mounting shaft 46. The pawl member 45 is constantly pressed toward the ratchet gear 44 by a biasing means (not shown). An appropriate number of the pawl members 45 can be provided on the circumference of the ratchet gear 44, for example, four in a uniform arrangement.

With such a configuration, the rotational force in one direction of the flange 41 is transmitted from the flange 41 to the ratchet gear 44, but the rotational force in the other direction is not transmitted.

A pinion gear 25 is disposed at the other end of the sleeve 42 disposed on the outer periphery of the output shaft 23, and is integrally attached by bolts 27. The pinion gear 25 is
It meshes with the rack gear 17 formed on the rack member 18.

In this embodiment, the flange 4 is rotatably mounted on the sleeve 42 at a position facing the ratchet gear 44.
7 is provided, and supports the other end of the mounting shaft 46 that supports the claw member 45.

The operation of the driving device 20 having the above configuration will be described.

Now, it is assumed that the positioning guide 10 is located at the lowest position with respect to the crane suspension frame 2 as shown in FIG. When the drive motor 21 is biased in this state, the rotational force of the drive motor 21 is transmitted to the flange 41 via the speed reducer 22 and the output shaft 23. The rotational force of the flange 41 is determined by the claw member 45 and the ratchet gear 44.
Through which the pinion gear 25 is driven to rotate clockwise in FIG.
When the pinion gear 25 is driven to rotate, the rack member 18, that is, the positioning guide 10 is lifted upward.

When the positioning guide 10 is raised to a predetermined height, the drive motor 21 is stopped, and the output shaft 2
3, i.e., the flange 41 does not rotate in the opposite direction, so that the positioning guide 10 is held at its height position.

The electrode transport device 1 is transported to a desired position above the electrolytic cell by operating a crane device.
Next, the hoisting device is driven to lower the crane suspension frame 2, and the positioning member concave portion 14 of the positioning guide 10 is fitted to the pin 101 provided in the electrolytic cell 100. As described above, according to the present embodiment, the pin guide 11 can be fitted to the pin 101 in a state where the position of the crane suspension frame 2 with respect to the electrode transport device 1 is set to an arbitrary position.

Subsequently, the hoisting device is driven to further lower the crane suspension frame 2, and the electrode plate P transported by the crane suspension frame 2 is loaded into the electrolytic cell 100, for example.

At this time, the electric motor 21 is stopped, and therefore, the output shaft 23 and the flange 41 (47) are also in the rotation stopped state, but the pawl member 45 of the latch device 40 is the same as that of the ratchet gear 44 shown in FIG. Allows rotation in the clockwise direction, so that the crane suspension frame 2 can descend along the pin guide 11 by its own weight. FIG. 5 shows a state in which the crane suspension frame 2 has been lowered to the lowermost position.

When the loading of the electrode plate P into the electrolytic cell 100 is completed, the hoisting device is driven to lift the crane suspension frame 2 upward. The pinion gear 25 meshing with the rack gear 17 of the positioning guide 10 tries to rotate counterclockwise by moving the crane suspension frame 2 upward, but the rotation is prevented by the latch device 40, Therefore,
The positioning guide 10 can be lifted upward while being held at the current position. Of course, by rotating the electric motor 21 in the other direction, or by releasing the brake device or the like provided on the speed reducer 22, furthermore,
By removing the claw member 45 of the latch device 40 from the ratchet gear 44, the positioning guide 10 can be moved downward with respect to the crane suspension frame 2, for example, to the state shown in FIG.

Embodiment 2 FIG. 6 shows another embodiment of the positioning guide 10.

For example, when loading the electrode plate P into the electrolytic cell 100, the electrode plate P is connected to the hook 2a of the crane suspension frame 2.
It is necessary to slightly lift or lower the crane suspension frame 2 when removing it from (FIG. 7).

When the positioning member 12 is fixedly attached to the lower end of the pin guide 11 by the positioning guide 10 as in the first embodiment, the positioning guide 1
If the operation of raising and lowering 0 is not performed delicately, there is a possibility that the positioning member 12 may come off the pin 101.

Therefore, in this embodiment, the positioning member 12
Is attached to the lower end of the pin guide 11 so as to be stretchable.

That is, according to the present embodiment, the positioning member 12 is composed of the tip concave member 51 having the conical concave portion 14 for fitting with the positioning pin 101 and the tip concave member 5.

On the other hand, a substantially cylindrical bearing member 54 is integrally attached to a lower end of the pin guide 11 by a bolt 55 or the like, on a flange 53 integrally attached thereto. The guide member 52 is slidably fitted to the bearing member 54.

A lower end 57 of a stepped guide rod 56 is integrally attached to an upper end of the guide member 52. The distal end portion 58 of the stepped guide rod 56 is adjacent to the lower end of the pin guide 11 and is fixed to the inner surface of the guide plate 5.
9 and protrudes upward through the through holes 60. A stopper 61 is provided at the upper end of the stepped guide rod 56 with a bolt 62.
To prevent the positioning member 12 from falling downward.

Further, around the stepped guide rod 56,
A compression spring 63 is disposed between the stopper 59 and the lower end 57 of the stepped guide rod, and constantly biases the positioning member 12 downward. FIG. 6A shows the positioning guide 10.
FIG. 6B shows a state when the positioning guide 10 is maximally contracted. In the present embodiment, the expansion / contraction width S between the time when the positioning guide 10 is maximally extended and the time when the positioning guide 10 is contracted is not limited to this.
