Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to an improvement in an apparatus for peeling off a seed plate on which metal is electrodeposited from an electrolytically generated cathode mother plate in electrolytic refining of metals.

<Problems to be solved by conventional technology and invention> Conventionally, for example, when preparing a seed plate used as a cathode when electrolytically refining copper, a thin copper plate was electrodeposited on the mother plate, then the copper plate was peeled off from the mother plate, and a hanger was attached to the beam. It is installed and used. Therefore, in order to use a seed plate electrodeposited on a cathode mother plate as a cathode for electrorefining, it is necessary to peel it from the mother plate without bending or wrinkles as much as possible. If it is bent or damaged during peeling from the mother plate, it cannot be used as a seed plate in an electrolytic cell, so it must be separately removed from the line and treated so that it can be used. This seed plate is extremely thin, approximately 1 mm or less, and is electrodeposited on the inside of the insulating material provided in a frame shape around the edge of the base plate, so it is difficult to peel it off using a machine without damaging the base plate. For this reason, the seed plate was first peeled off at the corner using a wedge, and then the seed plate was peeled off from the base plate using a saw blade made of oak. This work is hard work and requires skill, making it difficult to adapt to changes in the processing capacity of the electrolytic plant.

Further, as a mechanical stripping device, there are previously filed Japanese Patent Laid-Open No. 59-50189 and Japanese Patent Application No. 57-161938. The operation of this device will be explained with reference to FIG. 4. Before the base plate 6 is moved by the transfer device 1 to the separation position of the seed plate, the base plate 6 is at a stop position, as shown in the base plate 6 on the right side of the figure. upper corner 1 in front of the seed plate 10 in the direction of movement
Peel off 0a using a wedge.

Thereafter, the mother plate 6 is transferred to the transfer device 1 toward the peeling device 2.
When the tip 15 of the scraper 13 is transferred
enters between the partially separated mother plate 6 and seed plate 10, and as shown in the mother plate 6 in the center of FIG. 4, the seed plate 10
Peel off the upper end of the base plate 6 over its entire length. The movement of the mother plate 6 by the transfer device 1 is stopped in a state where the upper edge of the seed plate 10 is separated from the mother plate 6 over its entire length. Next, the suction rotation device 19 is activated to hold the seed plate 10 with the suction cup 20, and then the drive device 17 is activated to lower the scraper 13 from the upper edge of the seed plate 10 to below the lower end of the mother plate 6 to remove the seed. The entire surface of the board 10 is peeled off from the base board 6. The seed plate 10 peeled off from the mother plate 6 is held by the suction cup 20 and rotated outward at 90°.
It is rotated down and placed into position. After the seed plate 10 is removed from both sides of the mother plate 6, the transfer device 1 moves the mother plate 6 to the next position, and the scraper 13 is returned to the raised position before the next mother plate 6 arrives. It's summery.

However, in this device, the scraper 13 is bifurcated, and the common base 14 is connected to the vertical guide rail 1.
Since the seed plate 10 is fixed to a support 12 that slides along the base plate 1 and is driven by a single cylinder 17, when the seed plate 10 is peeled off with the scraper 13, the seed plate 10 may become uneven or the next mother plate may be scraped off. When the plate 6 enters, the tip part 15 swings horizontally, making it difficult to insert the mother plate 6 smoothly between the scrapers 13, requiring a worker to adjust the position each time, making automation difficult. It was hot.

<Means for Solving the Problems> In order to provide a seed plate peeling device that solves the above-mentioned problems, this invention includes a transfer device that suspends the base plate and moves it laterally intermittently, and a temporary stop of the transfer device. a peeling device provided at the position, the peeling device comprising:
A pair consisting of two pairs of guide posts arranged vertically opposite to each other on both sides of the path of the mother plate suspended by the transfer device at the one stop position of the transfer device, and a bush inserted through each guide post. and a scraper support device extending horizontally from the front edge of the base plate in the traveling direction to the rear edge of the base plate in the traveling direction along both sides of the base plate stopped at the one stop position so as to be substantially in contact with both sides of the base plate. It consists of a pair of scrapers, each of which is fixed to the bush near both ends thereof, a pair of drive shafts which are respectively engaged with both ends of each scraper, and a mechanism for synchronously driving the pair of drive shafts. It is equipped with a scraper drive device.
