Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electrode plate transport device that supplies and discharges a large number of electrode plates to an electrolytic cell for electrolytic refining or collection of non-ferrous metals such as copper and lead. The crane suspension frame is moved horizontally to the upper side of the electrolytic cell by being transported by the crane device, and the crane suspension frame is moved up and down at that position to insert the electrode plate into a predetermined position of the electrolytic cell, or from the electrolytic cell to the electrode. The present invention relates to an electrode plate conveying device for extracting a plate.
[0002]
[Prior art]
The present applicants have proposed an electrode plate conveying apparatus as disclosed in Japanese Patent Application Laid-Open No. 9-249985. This electrode plate conveying apparatus will be briefly described with reference to FIG.
[0003]
That is, the electrode plate conveying apparatus 1 of this example has the 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 apparatus can move the electrode plate transport apparatus 1 to a position of an arbitrary electrolytic cell of the electrolytic cells 100 arranged in parallel.
[0004]
The electrode plate transport 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 into the electrolytic cell 100. The battery is charged or removed from the electrolytic cell 100.
[0005]
Since the position of the electrode plate P in the electrolytic cell 100 cannot be made constant only by movement control of the crane device, manual readjustment of the electrode plate 100 is required.
[0006]
Therefore, the electrode plate transport device 1 stops the swing of the crane suspension frame 2 due to the movement of the crane device, and is caused by the collision between the electrode plate P and the electrolytic cell 100 that occurs when the electrode plate P is inserted into the electrolytic cell. A positioning guide 10 is provided to prevent damage and to position the crane suspension frame 2 with respect to the electrolytic cell 100 with higher accuracy. The positioning guide 10 is fitted to a positioning pin 101 provided in the electrolytic bath 100 when the electrode plate transport device 1 is transported to a predetermined electrolytic bath 100 position, and the crane suspension frame 2 is prevented from shaking and positioning. It is set as the structure which performs.
[0007]
In other words, the electrode conveying device 1 is provided with positioning guides 10 via the slide bearings 3 attached to both ends in the longitudinal direction 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 the lower end of the pin guide 11. A stopper 13 is provided at the upper end of the pin guide 11 so that the pin guide 11 does not fall off from the slide bearing 3, and a conical recess 14 is formed at the lower end of the positioning member 12 as shown in FIG. ing.
[0008]
On the other hand, as shown in FIGS. 7 and 8, a convex positioning pin 101 is arranged on the upper surface of the side wall of the electrolytic cell 100. When the crane suspension frame 2 is lowered, the concave portion 14 of the positioning member 12 is The convex positioning pin 101 is fitted.
[0009]
With such a configuration, the electrode plate transport device 1 can stop the crane suspension frame 2 from shaking and can position the crane suspension frame 2 with respect to the electrolytic cell 100 with higher accuracy. Since the electrode plate can be inserted into or removed from the electrolytic cell, it is easy to adjust the arrangement of the electrode plate in the electrolytic cell manually by the operator. It is said.
[0010]
[Problems to be solved by the invention]
However, when the inventors actually manufactured the electrode plate conveying device 1 having the above-described configuration and used it for conveying and replacing the electrode plate P, the positioning guide 10 has a stopper 13 attached to the slide bearing 3. In the state of contact, the crane is suspended from the crane suspension frame 2 by its own weight. For this reason, the crane device is moved to a sufficiently high position so that the lower end portion of the positioning guide 10 does not collide with the electrolytic cell 100 or other equipment. It was essential to move the suspension frame 2 in a lifted state.
[0011]
Therefore, conventionally, the positioning member 12 of the positioning guide 10 can be inserted into the positioning pin only when the crane suspension frame 2 is at a certain height. This means that the crane suspension frame 2 is kept high in various problems when actually using the electrode plate transport device 1, for example, in a place other than the electrolytic bath, or when the positioning pin 101 is not used. The problem of having to move is caused.
[0012]
Moreover, in the electrode plate transport apparatus 1 having the above configuration, when the crane suspension frame 2 is finely adjusted up and down when the electrode plate P is inserted into the electrolytic cell 100, the positioning member 12 of the positioning guide 10 is positioned on the electrolytic cell. There was a problem that the pin 101 was detached and fine adjustment was not possible.
[0013]
Therefore, an object of the present invention is to provide a very convenient electrode that can move the crane suspension frame at an arbitrary height and thereby insert the positioning guide into the positioning pin at an arbitrary height. It is to provide a plate conveying device.
[0014]
Another object of the present invention is that the positioning guide does not come off from the positioning pin, and the crane suspension frame can be finely adjusted up and down when the electrode plate is inserted into the electrolytic cell. It is to provide a plate conveying device.
[0015]
[Means for Solving the Problems]
The above object is achieved by the electrode plate transport device 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 a bearing means so as to be movable up and down, In the electrode plate transport device that is transported and positioned above the electrolytic cell,

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the electrode plate transport device according to the present invention will be described in more detail with reference to the drawings.
[0020]
The overall structure of the electrode transport apparatus 1 of the present invention is the same as that of the conventional electrode transport apparatus 1 shown in FIG. 7 described above. The members having the same functions are denoted by the same reference numerals and detailed description thereof is omitted, and the configuration of the motor-driven positioning guide 10 that characterizes the present invention will be described in detail below.
[0021]
FIG. 1 to FIG. 5 show an embodiment of a motor-driven positioning guide 10 that constitutes a characteristic part of the electrode transport apparatus 1 of the present invention.
[0022]
In the present embodiment, the positioning guides 10 are arranged at both ends in the longitudinal direction of the crane suspension frame 2 and can be moved in the vertical direction by the slide bearing means 3 as in the prior art. The positioning guide 10 also has a pin guide 11 and a positioning member 12 provided at the lower end thereof, as in the conventional case.
[0023]
According to the present embodiment, the slide bearing means 3 is incorporated into the frame frame 31 and the frame frame 31 integrally attached to the crane suspension frame 2 as understood with reference to FIGS. And a roller assembly 32. The roller assembly 32 includes an upper roller assembly 32A and a lower roller assembly 32B. The upper roller assembly 32A and the lower roller assembly 32B have the same configuration and are spaced apart from each other by a predetermined distance. In this embodiment, each roller assembly 32 (32A, 32B) is configured such that four rollers 33 are arranged evenly on the peripheral surface of the pin guide 11 and the roller rotation shaft 34 is horizontal. Each roller 33 is in rolling contact with the surface of the pin guide 11.
[0024]
Therefore, the pin guide 11, that is, the positioning guide 10 is supported by the upper roller assembly 32A and the lower roller assembly 32B, and can linearly move in the vertical direction.
[0025]
In this embodiment, the pin guide 11 is an elongated pipe having a length L0 of about 250 cm, an outer diameter D0 of 12 cm, and an inner diameter D1 of 8 cm, an upper end sealed by a plug cover 15, and a positioning member 12 at the lower end. Is installed. The positioning member 12 has a concave portion 14 opened downward in a conical shape at a lower end portion thereof, and an inverted V-shaped groove 16 extending in a direction perpendicular to the axis line at the tip of the concave portion. The concave portion 14 can be fitted to a conical convex member (positioning pin) 101 having a complementary shape with the concave portion 14 installed on the electrolytic cell 100 side.
[0026]
According to the present embodiment, a rack member 18 having a rack gear 17 formed over a predetermined length along its longitudinal axis is integrally attached to the pin guide 11. According to this embodiment, the rack member 18 is provided over a length L3 = 167 cm from a position below the distance L2 = 3 cm from the upper end of the pin guide.
[0027]
On the other hand, the frame frame 31 is provided with a drive device 20 that meshes with the rack gear 17 of the rack member 18 and drives the positioning guide 10.
[0028]
In particular, referring to FIG. 4, according to the present embodiment, the drive device 20 includes an electric motor 21 and a speed reducer 22 as drive sources. The output shaft 23 from the speed reducer 22 extends in the horizontal direction, and the tip thereof is carried by a bearing 24 installed on the frame frame 31. The output shaft 23 includes a pinion gear device 26 that includes a pinion gear 25 that meshes with the rack gear 17, and a latch device 40 that serves as a one-way rotational force transmission unit that transmits only one-way rotational force to the pinion gear device 26. Is placed.
[0029]
First, the latch device 40 will be described.
[0030]
The output shaft 23 is integrally provided with a flange 41 that constitutes a drive member at a position adjacent to the speed reducer 22, and a sleeve is coaxially disposed between the flange 41 and the bearing 24 on the outer periphery of the output shaft 23. 42 is arranged.
[0031]
A ratchet gear 44 as a driven member is integrally attached to the end of the sleeve 42, that is, the end facing the flange 41 by a bolt 43. Further, a claw member 45 that meshes with the ratchet gear 44 and transmits a one-way rotational force to the ratchet gear 44 is disposed on the flange 41 via an attachment shaft 46 so as to be swingable. The claw member 45 is always pressed toward the ratchet gear 44 by an urging means (not shown). The claw members 45 can be provided in an appropriate number, for example, four, in a uniform arrangement on the circumference of the latitudinal gear 44.
[0032]
With this configuration, the rotational force in one direction of the flange 41 is transmitted from the flange 41 to the latitudinal gear 44, but the rotational force in the other direction is not transmitted.
[0033]
A pinion gear 25 is disposed on the other end of the sleeve 42 disposed on the outer periphery of the output shaft 23 and is integrally attached with a bolt 27. The pinion gear 25 meshes with a rack gear 17 formed on the rack member 18.
[0034]
In the present embodiment, a flange 47 is rotatably disposed at a position of the sleeve 42 facing the latitudinal gear 44 and supports the other end of the mounting shaft 46 that supports the claw member 45.
[0035]
An operation mode of the drive device 20 configured as described above will be described.
[0036]
Now, it is assumed that the positioning guide 10 is located in a state where it is lowered most with respect to the crane suspension frame 2 as shown in FIG. When the drive motor 21 is energized 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 transmitted to the sleeve 42 via the claw member 45 and the ratchet gear 44, whereby the pinion gear 25 is rotationally driven clockwise in FIG. When the pinion gear 25 is rotationally driven, the rack member 18, that is, the positioning guide 10 is lifted upward.
[0037]
When the positioning guide 10 is lifted to a predetermined height position, the drive motor 21 is stopped, and the output shaft 23, that is, the flange 41 is rotated in the reverse direction by the action of a brake device provided in the speed reducer 22, for example. Therefore, the positioning guide 10 is held in its height position.
[0038]
The electrode transfer device 1 is transferred to a desired electrolytic cell upper position by operating the crane device. Next, the hoisting device is driven to lower the crane suspension frame 2 so that the positioning member recess 14 of the positioning guide 10 is fitted to the pin 101 provided in the electrolytic cell 100. Thus, 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.
[0039]
Subsequently, the hoisting device is driven to lower the crane suspension frame 2 further. For example, the electrode plate P conveyed by the crane suspension frame 2 is inserted into the electrolytic cell 100.
[0040]
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. However, the claw member 45 of the latch device 40 is the timepiece shown in FIG. Since the rotation in the direction is allowed, the crane suspension frame 2 can be lowered along the pin guide 11 by its own weight. FIG. 5 shows a state where the crane hanging frame 2 is lowered to the lowest position.
[0041]
When the electrode plate P is inserted into the electrolytic cell 100, the hoisting device is driven to lift the crane suspension frame 2 upward. The pinion gear 25 meshed with the rack gear 17 of the positioning guide 10 tries to rotate counterclockwise by moving the crane suspension frame 2 upward, but is prevented from rotating by the latch device 40, Therefore, the positioning guide 10 can be lifted upward while being held at the current position. Of course, the claw member 45 of the latch device 40 is further removed from the ratchet gear 44 by rotating the electric motor 21 in the other direction or by releasing the brake device provided in the speed reducer 22. Thus, the positioning guide 10 can be moved downward relative to the crane suspension frame 2, for example, to the state shown in FIG.
[0042]
Example 2
FIG. 6 shows another embodiment of the positioning guide 10.
[0043]
For example, when inserting the electrode plate P into the electrolytic cell 100, it is necessary to slightly lift or lower the crane suspension frame 2 when the electrode plate P is removed from the hook 2a (FIG. 7) of the crane suspension frame 2. is there.
[0044]
In the case where the positioning member 12 is fixedly attached to the lower end of the pin guide 11 by the positioning guide 10 as in the case of the first embodiment, the positioning guide 10 may be positioned without performing an operation for raising and lowering the positioning guide 10 slightly. The member 12 may be detached from the pin 101.
[0045]
Therefore, in this embodiment, the positioning member 12 is attached to the lower end of the pin guide 11 so as to be extendable.
[0046]
In other words, according to the present embodiment, the positioning member 12 includes the tip recess 51 formed with the conical recess 14 for fitting with the positioning pin 101, and the pipe-shaped guide protruding upward from the tip recess 51. Member 52.
[0047]
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 attached integrally. The guide member 52 is slidably fitted to the bearing member 54.
[0048]
A lower end portion 57 of a stepped guide rod 56 is integrally attached to the upper end of the guide member 52. The front end 58 of the stepped guide rod 56 passes through the through hole 60 of the guide plate 59 that is fixed to the inner surface adjacent to the lower end of the pin guide 11 and protrudes upward. A stopper 61 is fixed to the upper end of the stepped guide rod 56 with a bolt 62 to prevent the positioning member 12 from dropping downward.
[0049]
Further, around the stepped guide rod 56, a compression spring 63 is disposed between the stopper 59 and the stepped guide rod lower end portion 57, and constantly urges the positioning member 12 downward. FIG. 6A shows a state when the positioning guide 10 is extended to the maximum, and FIG. 6B shows a state when the positioning guide 10 is most contracted. In this embodiment, the expansion / contraction width S between when the positioning guide 10 is fully extended and when it is contracted is not limited to this, but is 20 cm.
[0050]
In this embodiment, by adopting the above-described configuration, only the tip positioning member 12 of the pin guide 11 can be freely moved up and down. Thus, even if the crane suspension frame 2 is lifted, for example, until it is raised by 20 cm, the positioning member 12 has a structure that does not come off the pin.
[0051]
