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 tank used in a metal electrolytic factory, and in which these plates can be transferred in the same 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 hanging an electrode plate is attached to a base 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 electrolytic 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 cell 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 the electrodes 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 the tank, the main electrolysis can be carried out using existing equipment as is and with a shorter pitch between electrodes than in the past, making it possible to realize low-cost mass production.

However, in conventional general conveyance devices, the position of the hanging device is fixed with respect to the base, and the interval between the suspended electrode plates cannot be changed, and is generally fixed at a pitch of 100 mm.
On the other hand, as described in Japanese Patent Publication No. 62-5234, a large number of supports equipped with hanging devices are arranged in parallel on the frame in multiple rows on the left and right, so that a large number of electrode plates can be hung side by side. There is also known a device in which the respective supports are loosely connected to each other by a connecting device so that the pitch of the electrode plates can be changed.

[Problem that the invention seeks to solve]

The device described in the above-mentioned publication that can change the electrode pitch is used to reduce the electrode distance in response to the thinner anode thickness when performing the second electrodeposition on a new cathode during electrolysis work. Since this is the type of material that is used, the distance between the poles that can be changed is quite short. That is, the ring-shaped connectors that connect adjacent supports are not in contact with each other, and both ends thereof are pin-coupled to each end of the adjacent support. 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]

The electrode plate transport device, which can take in and out multiple electrode plates at once, has a structure that allows the pitch between the electrodes to be changed more greatly than before, so it can be mass produced at low cost using existing equipment, and the overall It is an object of the present invention to provide an electrode plate conveying device which has a simple basic structure and whose driving portion operates reliably.

[Means for solving problems]

Next, the means to solve the above problems,
Embodiments will be explained with reference to drawings corresponding to embodiments.

That is, the electrode plate conveying device of the present invention includes a plurality of beam members 8, 8a, 8b, 8c suspended from the base (holding frame 4) in parallel with each other so as to be movable in a direction orthogonal to the longitudinal direction thereof. , a plurality of hanging hooks 12 and 13 that are attached to each of the beam members and hang the electrode plates (cathode 14, anode 17), and a plurality of turning means (torque actuators) that independently turn each of the hanging hooks. Eta18)
and a telescopic link mechanism 9 that connects each of the beam members to each other with adjustable intervals by link plates in which doubly overlapping connection points are successively connected by pins and elongated holes; a screw shaft 19 which can be driven freely and engaged with a nut member 24 provided at the end of the beam member; A top 7 is provided with a bearing member 6 on its upper surface that slidably engages with a moving rail 5 provided on the lower surface of the frame, and the link mechanism is connected to its side surface.
and an adjustment piece 11 that is removably provided on opposing surfaces of the piece.

[Effect]

A plurality of hanging hooks 12, 13 for hanging each electrode plate
are attached to each common beam member, and each hanging hook 12, 13 is independently driven by a turning means (torque actuator 18) as required. Each of the plurality of beam members movably suspended from the base body is sequentially pushed by the endmost beam member driven by the screw shaft 9 via the nut member 24, and the bearing member on the upper surface of the piece 7 is pushed. 6 engages with the moving rail 5 and moves, but since each beam member is connected by a telescopic link mechanism 9 consisting of double overlapping link plates at the connection point, the beam member is suspended from each beam member. The pitch of the electrode plates can be changed within a wider range than conventionally. The pitch between each electrode plate is determined by the length of the adjustment piece 11, and when adjusting the pitch to be longer or shorter, each adjustment piece may be replaced with a longer or shorter adjustment piece.

〔Example〕

As shown in FIG. 2, the conveyance device 1 of this embodiment has a base body of a longitudinally rectangular holding frame 4 suspended from an overhead crane 3 via a turntable 2. A pair of moving rails 5, 5, which are approximately circular in cross section, are fixed in parallel to each other on the lower surface of both longitudinal sides 4a, 4a of the holding frame 4, and a large number of bearing members 6 are mounted on the moving rails 5. It is slidably engaged. Each pair of bearing materials 6, 6 provided on the pair of moving rails 5, 5 is connected to each pair of pieces 7, 7.
Each pair of pieces 7, 7 is fixed on both sides of the upper surface of a large number of beam members 8, which are longer than the width of the holding frame 4. That is, a large number of beam members 8 are arranged parallel to each other via the moving rails 5, bearing members 6, and pieces 7 so that the beam members 8 are movable along the longitudinal direction of the holding frame 4 in a posture orthogonal to the same longitudinal direction. It is suspended from the lower surface of the holding frame 4. Further, the number of beam members 8 attached to the holding frame 4 is such that it fits within the length of the holding frame 4 when they are arranged side by side at the maximum pitch, which will be described later. The shapes of the moving rail 5 and the bearing material 6 are as follows:
It may also be a dovetail groove as shown in FIG.

Next, a large number of beam members 8 movably suspended from the lower surface of the holding frame 4 are connected to each other by link mechanisms 9 at both side surfaces of the frame 7, respectively. This link mechanism 9 consists of a link plate 10 having a long hole 10a and a round hole 10b, each link plate 10 has a portion of the long hole 10a and a round hole 1.
They are overlapped at the portion 0b and connected to the center of both sides of each piece 7 with a pin. Adjacent pieces 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 that can be expanded and contracted. That is, as shown in FIG. 6b, in the extended position of the link mechanism 9 where the pin is engaged with the outer edge of the elongated hole 10a, the center distance between the pieces 7 (i.e., the distance between the pins P) becomes the maximum value P of the pitch between the poles, which will be described later, and the interval between the opposing adjustment pieces 11, 11 becomes the change length of the pitch between the poles. Further, as shown in FIG. 6a, when the link mechanism 9 contracts and the opposing adjustment pieces 11, 11 come into contact, the pitch between the poles becomes the minimum value P'. Therefore, by changing the thickness of the adjusting piece 11, the length of the pitch between the electrodes can be changed. Further, as shown in FIG. 3, among the plurality of beam members 8 connected by the link mechanism 9, the beam member 8a suspended below the center of the holding frame 4 is attached to the holding frame 4 side by a fixing means (not shown). The position is fixed. Therefore, the beam members 8, which are 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. It's summery.

Next, each beam member 8 has a pair of pieces 7, 7.
A pair of hanging hooks 12, 12 are suspended from the center of the beam member 8 at an inner position.
Also, in both positions outside the pair of pieces 7, 7,
A pair of hanging hooks 13, 13, which are slightly longer than the hanging hook 7, are suspended. A pair of these hanging hooks 12, 13 provided on each beam member 8 are provided with hook portions 12a, 13a at their lower ends, as shown in FIG. As shown in FIG. 1, the left and right sides of a hanging rod 16 inserted through a ribbon 15 of a cathode 14 serving as an electrode plate are hooked to a pair of inner hanging hooks 12, 12. In addition, the pair of hanging hooks 13, 13 on the outside are provided with ear projections 17a, 1 at the upper end of the anode 17 as a pole plate.
7a is hooked. Next, as shown in FIG. 7, 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 serve as turning means provided on the upper surface of the beam member 8. They are respectively operatively connected to the torque actuator 18. Each torque actuator 18 is designed to be driven independently, and as shown by the imaginary line in FIG.
3 can rotate its hook portions 12a and 13a as necessary.

Next, at both ends of the holding frame 4 in the longitudinal direction, a moving rail 5 is placed at the center position of the moving rails 5, 5.
Screw shafts 19, 19 are provided in parallel with. As shown in FIGS. 1 to 4, this screw shaft 19 is
One end of the fixed beam member 8a, which has a length of about 1/6 of the length of the holding frame 4, is supported by a bearing 20 provided on the cross member 4b of the holding frame 4. Bearing 21 provided on the cross member 4b at the end of
The other end is supported. 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 in the holding frame 4.
is meshed with the driven sprocket 22. A nut member 24 is fixed at the center of the upper surface of each beam member 8b, 8b at both ends of a large number of parallel beam members 8 connected by a link mechanism 9, and this nut member 24, 24 is the screw shaft 1
9 and 19, respectively. Therefore, by driving the motor M and rotating the screw shaft 19 via both sprockets 22 and 23, the nut member 24
The two endmost beam members 8b, 8b provided on the screw shaft 19 are advanced toward the center of the holding frame 4 while pushing the other beam members 8 through the link mechanism 9.
The beam members 8 connected by the beam members 8 are gathered around the central beam member 8a whose position is fixed, so that the mutual spacing between them is minimized. Although details are not shown, an electromagnetic brake is provided on the screw shaft 19 to prevent the screw shaft 19 from rotating in the opposite direction due to reaction, so that the beam member 8 can be reliably positioned at a 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 the poles of the electrode plates suspended from each beam member 8 via the hanging hooks 12 and 13 is set to a maximum value P (for example, 100 mm). ). In this state, the hanging hooks 12, 12 and the hanging hook 1
Cathode 14 and anode 17 at 3 and 13 respectively
hanging, overhead crane 3 and turntable 2
Each electrode plate is transferred onto the electrolytic cell by operating the above, and the overhead crane 3 is lowered to place both ends of the hanging rod 16 and the lug 17a of the anode 17 on the side edge of the cell. Next, each torque actuator 18 is operated to rotate each hanging hook 12, 13, the hooks 12a, 13a of the hanging hook 12, 13 are removed from the electrode plate, and the holding frame 4 is pulled up. Hanging hook 1
If 2 and 13 are separated from the electrolytic cell, all the electrode plates for one cell can be efficiently put into the cell in one operation.

Moreover, in order to take out the electrode plate from the tank, it is sufficient to repeat the above-mentioned operation in the reverse order. Then, when transporting each of the lifted electrode plates to the electrolytic cell for the next process, if the screw shaft 19 is driven by the motor M and the beam members 8b and 8b at the end are moved toward the center, each The beam members 8 are pushed to narrow the interval, and the pitch between the electrode plates suspended from each beam member 8 can be set to be appropriately reduced. 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, 70 mm). Can be set to . Therefore, the electrode pitch can be shortened from 100 mm to 70 mm while the equipment other than the electrode plate conveying device 1 according to this embodiment remains the same, and low-cost mass production can be realized in metal electrolytic smelting. can.

As explained above, the electrode plate conveying device 1 of this embodiment
According to the above, since the structure is such that a longitudinal beam member 8 larger than the width of the holding frame 4 is directly suspended from the lower surface of the holding frame 4, as many as four hanging hooks 1 are attached to one beam member 8.
2 and 13 can be provided, and both the anode and cathode plates can be suspended at the same time with a simple configuration. In addition, the torque actuators 18 that swing and drive each of the hanging hooks 12 and 13 operate independently and are not interlocked, so even if one part breaks down, there is no risk of it having an adverse effect on the whole. Further, the link mechanism 9 of this embodiment has a circular hole 10b in the link plate 10 and a link plate 10 in the link plate 10.
The elongated hole 10a is overlapped twice, and each beam member 8 is connected to each beam member 8 with a pin at one point in this overlapped portion. Therefore, according to the link mechanism 9 of this embodiment, the adjustable range of the pitch between poles is larger than that of the conventional one, so that it can 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 example,
A motor M1 is provided on the axis of the screw shaft 19, and a torque device 31 is interposed between the screw shaft 19 and the motor M1, which becomes a slip state when the torque exceeds a certain level and stops transmitting any more torque. has been done. Further, the screw shaft 19 and motor M1 of this embodiment are only provided in one set on the right side of the holding frame 4 in FIG. 8a, and the left end beam member 8c is fixed in position to the holding frame 4. ing. When the pitch between poles is shortened, each beam member 8 is
In figure a, they are gathered at the left end.
