Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is capable of simultaneously loading and unloading a large number of electrode plates into and out of an electrolytic cell used in a metal electrolytic factory. This invention relates to an electrode transport device used for transporting plates in bulk.

[Conventional technology]

For example, in an electrolytic cell used for copper electrolysis, a transport device is used in which a suspension device for suspending an electrode plate is attached to a base body that is supported by an overhead crane so as to be movable in horizontal and vertical directions. Then, a large number of electrode plates consisting of cathodes and anodes are suspended from a hanging tool and aligned, and in this state, these electrode plates are collectively taken in and out of an electrolytic cell or transferred to an electrolytic cell for the next process.

By the way, in electrolysis work, the shorter the distance between the electrode plates in the electrolytic cell (hereinafter referred to as the pitch between the electrodes), the more the number of electrode plates per tank can be increased, which makes it more efficient. can be operated. Therefore, from the viewpoint of reducing production costs, it is desirable to shorten the pitch between poles as much as possible. For example, the pitch between the electrodes in an electrolytic cell for producing seed plates is generally 100 mm, but when transferring and charging the electrolytic cell into the main electrolytic cell for the next process using the conveying device, the pitch between the electrodes is set to about 70 mm, for example. If it can be shrunk and put into a tank, the main electrolysis can be performed using existing equipment as is and with a shorter pitch between electrodes than in the past, making it possible to achieve low-cost mass production.

However, in conventional general conveyance devices, the position of the hanging tool is fixed relative to the base, and the interval between the suspended electrode plates cannot be changed, and the pitch is generally fixed at 100 mm. . In contrast,
As described in Publication No. 5234, a large number of supports equipped with hanging tools are arranged in parallel on a frame in multiple rows on the left and right, so that a large number of electrode plates can be hung side by side, and each support is connected to each other by connecting tools. Devices that are loosely connected to allow the pitch of the electrode plates to be changed are also known.

[Problem that the invention seeks to solve]

The device described in the above publication that can change the pitch between electrodes is used to reduce the distance between electrodes in response to the thinner anode thickness when performing second electrodeposition on a new cathode during electrolysis work. Since it is used for many years, the distance between the poles of the change was quite short. That is, the ring-shaped connectors connecting adjacent supports are not in contact with each other, but have a structure in which both ends are connected to each end of the adjacent supports. For this reason, it is necessary to space the pins at both ends of each support by the length of the pitch change to be adjusted, which makes it unreasonable to make the pin diameter considerably smaller in order to increase the length of change to a certain extent. occurs.

(Purpose of the invention) In a plate conveying device that can load and unload a large number of plates at once, the structure allows the pitch between the plates to be changed more greatly than before, so it can be carried out in large quantities at low cost using existing equipment. The object of the present invention is to provide an electrode plate conveying device that can be easily produced, has a simple overall basic structure, and has a reliable operation of the driving part.

Holding frame 4 A pair of moving rails 5.5 having a substantially circular cross section are fixed in parallel to each other on the lower surfaces of both longitudinal sides 4a, 4a, and a large number of bearing members 6 are slidably mounted on the moving rails 5. Each pair of bearing members 6.6 provided on the pair of moving rails 5.5 is fixed to the upper surface of each pair of pieces 7.7, and .7 are respectively fixed to both sides of the upper surface of a large number of beam members 8 which are longer than the width dimension of the holding frame 4. That is, the large number of beam members 8 are arranged in a posture perpendicular to the longitudinal direction of the holding frame 4 and extend along the same longitudinal direction. They are suspended from the lower surface of the holding frame 4 in parallel to each other via a moving rail 5, a bearing material 6, and a piece 7 so as to be movable along the direction. The number of beam members 8 included in the holding frame 4 is the same as that of the holding frame 4 when arranged in parallel at the maximum pitch described later.

The bins are connected to each other. Adjacent frames 7°7
Adjustment pieces 11, 11 are removably provided on opposing surfaces of the link mechanism 9, respectively, and set the length of the link mechanism 9 to extend and contract. That is, as shown in FIG. 6(b), the link mechanism 9 has a bottle engaged with the outer edge of the long hole 10a.
At the extended position, the distance between the centers of the pieces 7 (that is, the distance between the pins P) or the maximum value P of the pitch between the poles, which will be described later, is determined, and the distance between the opposing adjustment pieces 11 and 11 is the change length of the pitch between the poles. Become. Further, as shown in FIG. 6(a), when the link mechanism 9 contracts and the opposing adjustment pieces 11 and 11 come into contact, the pitch between the poles becomes the minimum value P'. Therefore: By changing the thickness of the J8 regular piece 11, the change length of the pitch between poles can be changed. Also, as shown in Figure 3,
Among the plurality of beam members 8 connected by the link mechanism 9, the beam member 8a hanging below the center of the holding frame 4 is fixed in position on the holding frame 4 side by a fixing means (not shown). Therefore, the beam members 8 arranged in parallel and connected on both sides of the fixed beam member 8a can move along the moving rail 5 while expanding and contracting the distance between them. ing.

Next, a pair of hanging hooks 12.12 are suspended from each beam member 8 at positions inside the pair of pieces 7.7, with the center of the beam member 8 in between.

Also, at both positions outside the pair of pieces 7.7, there are a pair of hanging hooks 13.13 that are slightly longer than the hanging hooks 7.
are hanging down respectively. Seven pairs of these hanging hooks 12, 13 are provided on each beam member 8, and as shown in FIG. 7, hook portions 12a, 13a are provided at the lower ends. A pair of inner hanging hooks 12.1 as shown in FIG.

The upper ends of each of the hanging hooks 12 and 13 are inserted through holes (not shown) provided in the beam member 8 and protrude upward, and the torque actuator 1 as a turning means is provided on the upper surface of the beam member 8.
8, respectively. Each torque actuator 18 is designed to be driven independently, and each of the hanging hooks 12 and 13 can rotate its hook portions 12a and 13a as necessary, as shown by the imaginary lines in FIG. Can be done.

Next, at both ends of the holding frame 4 in the long plane direction, there is a screw @ at the center position of the moving rail 5.5 parallel to the moving rail 5.
19, 19 are provided. As shown in FIGS. 1 to 4, this screw shaft 19 has a length of, for example, 1/
One end of the fixed beam member 8a is supported by a bearing 20 provided on the cross member 4b of the holding frame 4, and the other end of the fixed beam member 8a is supported by a bearing 20 provided on the cross member 4b of the holding frame 4. Bearing 2
The other end is supported by 1. A driven sprocket 22 is fixed to the other end of the screw shaft 19, and a driving sprocket 23 of the motor M installed on the holding frame 4 meshes with the driven sprocket 22. A nut member 24 is fixed at the center of the upper surface of each of the beam members 8b, 8b at both ends of a large number of beam members 8 arranged in parallel. Therefore, if the motor M is driven and the screw shaft 19 is rotated through both sprockets 22 and 23, the end of the screw shaft 19 provided on the screw shaft 19 will be rotated through the nut member 24. Both beam members 8b, 8b are advanced toward the center of the holding frame 4 while pushing the other beam members 8, and each beam member 8 connected by a link mechanism 9 moves toward the center of the beam member 8a, which is fixed in position. The screw shafts 19 are gathered around each other so that the distance between them is minimized.Although details are not shown, an electromagnetic brake is provided on the screw shaft 19,
The screw shaft 19 is prevented from rotating in the opposite direction due to reaction, and the beam member 8
can be reliably positioned at the desired stopping position.

Next, the operation of the above configuration will be explained.

First, the beam members 8b and 8b at both ends are respectively positioned at both ends of the holding frame 4, and the pitch between poles of the electrode plates suspended from each beam member 8 via the hanging hooks 12, 13 is set to a maximum value P (for example, 1
00mm). In this state, the hanging hook 1
2.12 and hanging hook 13.13, respectively, suspend the cathode 14 and anode 17, operate the overhead crane 3 and turntable 2, and transfer each electrode plate onto the electrolytic cell.
Further, the overhead crane 3 is lowered and both ends of the hanging rod 16 and the ear projections 17a of the anode 17 are placed on the side edges of the rice cake. Next, each torque actuator 18 is operated to rotate each hanging hook 12.13, and the hook portion 12a of the hanging hook 12.13 is rotated.

Moreover, in order to take out the electrode plate from the cage, the above-mentioned operation may be repeated in the reverse order. Then, when transporting each lifted electrode plate to the electrolytic cell for the next process, the screw shaft 19 is
If the beam members 8b, 8b at the end are moved toward the center by driving the The reduction setting can be made as appropriate. For example, as shown by imaginary lines in FIGS. 1 to 3, if the endmost beam members 8b, 8b are driven to one end of the screw shaft 19, the pitch between the poles can be set to the minimum value P' (
For example, it can be set to 70 mm). Therefore, the equipment other than the electrode plate conveying device 1 according to this embodiment remains as it is,
The pitch between electrodes can be shortened from 100 mm to 70 mm, and low-cost mass production can be realized in metal electrolytic smelting.

As explained above, according to the electrode plate conveying device 1 of the present embodiment, the longitudinal beam member 8 larger than the width of the holding frame 4 is transferred to the holding frame 4.
Since the structure is suspended directly from the lower surface of the beam member 8, one beam member 8
As many as four hanging hooks 12.13 can be installed on the
With a simple configuration, both the anode and cathode plates can be suspended at the same time. Also each hanging hook 12.13
Each of the torque actuators 18 that drive the rotor to rotate operates independently and there is no interlocking relationship, so even if one part breaks down, there is no risk that the damage will affect the whole part. Further, the link mechanism 9 of this embodiment has a structure in which each beam member 8 is connected to each beam member 8 by a pin at one point in the link section. Therefore, according to the link mechanism 9 of this embodiment, the range of the pitch between poles that can be adjusted is larger than that of the conventional one, so that it is possible to meet the demands for low cost and mass production using existing equipment. Furthermore, the drive mechanism for changing the pitch between poles in this embodiment has a simple structure in which the suspended beam member 8 is driven by the nut member 24 and the screw shaft 19, so it has the effect of reducing failures and ensuring reliable operation. .

Next, FIG. 8 shows another embodiment of the present invention. The basic configuration of this electrode plate conveying device 30 is almost the same as that of the device 1, and corresponding components are given the same reference numerals and explanations will be omitted. In this embodiment, the motor M is placed on the axis of the screw shaft 19.
1 is provided, and a torque device 31 is interposed between the screw shaft 19 and the motor M1, which enters a slip state when the torque exceeds a certain level and stops transmitting any more torque. In addition, the screw @19 and motor M1 of this embodiment are only provided as a set on the right side of the holding frame 4 in FIG. 8(a), and the left end beam member 8c is located on the holding frame 4. Fixed. When the pitch between poles is shortened, each beam member 8 is pushed to the left end in FIG. 8(a).
