Description

本発明は、電着金属の剥取装置に関し、さらに詳しくは、電解製錬によって陰極板の表面に電着した金属を剥ぎ取るための電着金属の剥取装置に関する。   The present invention relates to an electrodeposited metal stripping device, and more particularly to an electrodeposited metal stripping device for stripping metal deposited on the surface of a cathode plate by electrolytic smelting.

ＩＳＡ方式によるパーマネントカソードを用いた金属の電解製錬、例えば、銅の電解精錬は、電解液が貯えられた電解槽中に多数のステンレス製の陰極板（カソード板）と、粗銅を鋳込んだ陽極板（アノード板）とを交互に浸漬して通電することにより、陰極板の両面に電気銅を電着させることによって行なわれる。そして、陰極板表面に電着した銅は、剥取装置によって剥ぎ取られ製品とされる。具体的には、図１に示すように、陰極板１は、ステンレス製の板状材で、その両サイド部には合成樹脂製のプロクテクタ５が嵌め込まれると共に、上端部にはクロスバー４が設けられている。また、クロスバー４の下部には２つの窓部３、３が設けられており、この窓部３、３に図示しない電極板搬送装置のフックを掛止することにより電解槽への装入及び取り出し並びに搬送が行なわれるようになっている。そして、陰極板１の表面に析出した電着金属２を剥取装置によって剥ぎ取りが行なわれる。そして、剥ぎ取られた電着金属はそのまま製品として又は電解製錬の種板として供されることとなる。   In the electrolytic smelting of metals using permanent cathodes by the ISA method, for example, the electrolytic smelting of copper, a large number of stainless steel cathode plates (cathode plates) and crude copper are cast into an electrolytic cell in which an electrolytic solution is stored. It is performed by electrodepositing electrolytic copper on both surfaces of the cathode plate by alternately immersing the anode plates (anode plates) and energizing them. The copper electrodeposited on the surface of the cathode plate is stripped off by a stripping device to obtain a product. Specifically, as shown in FIG. 1, the cathode plate 1 is a plate-shaped material made of stainless steel, and a protector 5 made of synthetic resin is fitted on both side portions thereof, and a crossbar 4 is formed on the upper end portion. Is provided. In addition, two windows 3 and 3 are provided at the lower part of the crossbar 4. By hooking the window plates 3 and 3 with a hook of an electrode plate conveying device (not shown), Removal and conveyance are performed. Then, the electrodeposited metal 2 deposited on the surface of the cathode plate 1 is stripped off by a stripping device. The stripped electrodeposition metal is used as a product as it is or as a seed plate for electrolytic smelting.

従来の電着金属の剥取装置にあっては以下のような動作によって電着金属の剥ぎ取りが行なわれていた。すなわち、電解槽から引き上げられた陰極板を剥取装置の受け入れ口（ロードイン）に装入する。装入された陰極板は洗浄室で洗浄されたあと、移載機によってトラバースコンベアに乗せられる。そして、図２に示すように、陰極板１は起立させた状態で基台１２０上に保持され（図２（ａ））、陰極板１の両側を押圧する（図２（ｂ））ことにより陰極板１と電着金属２との間に隙間を生じさせ（フレキシング）、この隙間にチゼル３５を装入（図２（ｃ））して落とし込むことによって陰極板１から電着金属２を引き剥がし（チゼリング）、引き剥がした電着金属２をさらに基台１２０と接する底部を基点として横倒（ダウンエンダ）することによって電着金属２を陰極板１から剥ぎ取る（図２（ｄ））。そして、ダウンエンダによって電着金属が割れずに陰極板から分離できなかった場合には、さらに電着金属を引き起こして再び横倒する「フラッピング」を行なって両者を分離する。   In the conventional electrodeposited metal stripping apparatus, the electrodeposited metal is stripped by the following operation. That is, the cathode plate pulled up from the electrolytic cell is inserted into the receiving port (load-in) of the stripping device. The loaded cathode plate is cleaned in the cleaning chamber and then placed on the traverse conveyor by the transfer machine. Then, as shown in FIG. 2, the cathode plate 1 is held on the base 120 in an upright state (FIG. 2 (a)), and both sides of the cathode plate 1 are pressed (FIG. 2 (b)). A gap is formed between the cathode plate 1 and the electrodeposited metal 2 (flexing), and a chisel 35 is inserted into the gap (FIG. 2 (c)) to drop the electrodeposited metal 2 from the cathode plate 1. The electrodeposited metal 2 is peeled off from the cathode plate 1 by peeling off (chiseling) and laying down (down-ending) the electrodeposited metal 2 that has been peeled off with the bottom contacting the base 120 as a base point (FIG. 2 (d)). . If the electrodeposited metal is not broken and cannot be separated from the cathode plate by the down-ender, the electrodeposition metal is further caused to “flapping” to fall again, thereby separating the two.

このような従来の剥取装置としては、例えば、特開２００１−８１５９１号公報（特許文献１）に示されたものがある。この剥取装置は、陰極板の端部に取り付けられている絶縁プロテクタの一部を取り外す絶縁プロテクタ取り外し装置と、取り外した一部の絶縁プロテクタの位置で定位置に固定されている陰極板と電着金属との間に挿入され電着金属の端縁部を陰極板から離して口開き状態とするチス刃および電着金属に吸着して電着金属を剥ぎ取り方向に移動させる複数の真空吸着パッドを備えて構成されている。そして、陰極板の表面と電着金属の端縁部との間にチス刃を押し込み、楔状のチス刃の楔作用によって陰極板から電着金属を剥がし、電着金属の端縁部を口開き状態とする。口開き状態となった電着金属を複数の真空吸着パッドによって吸着し、陰極板から引き離す（フラッピング）ことによって電着金属の剥ぎ取りを行うというものである。   As such a conventional peeling apparatus, there exists a thing shown by Unexamined-Japanese-Patent No. 2001-81591 (patent document 1), for example. This stripping device includes an insulating protector removing device that removes a part of the insulating protector attached to the end of the cathode plate, a cathode plate that is fixed in place at the position of the removed insulating protector, and an electric power source. Multiple vacuum suctions that are inserted between the electrodeposited metal and adsorbed on the electrode and the electrodeposited metal, with the edge of the electrodeposited metal separated from the cathode plate and moved in the stripping direction It is configured with a pad. Then, a chis blade is pushed between the surface of the cathode plate and the edge of the electrodeposited metal, the electrodeposited metal is peeled off from the cathode plate by the wedge action of the wedge-shaped chis blade, and the edge of the electrodeposited metal is opened. State. The electrodeposited metal in an open state is adsorbed by a plurality of vacuum suction pads and separated from the cathode plate (flapping) to peel off the electrodeposited metal.

しかし、これまでの剥取装置は、陰極板を載置する基台が平板状であったため陰極板から電着金属を剥ぎ取る際のダウンエンダによる電着金属の横倒しの角度が陰極板に対して最大９０°であり、１回の作業では電着金属を完全に剥ぎ取ることが出来ない場合があった。その場合には、フラッピングを１回乃至複数回行なう必要があった。１回乃至複数回のフラッピングによれば陰極板から電着金属を剥ぎ取ることは可能であるが、フラッピングを行なうということはそれだけ余分な時間が取られるということであり、時間当たりの処理量が減ってしまうという問題があった。具体的には、電着金属の剥ぎ取りをフラッピングなしで完了させたとすると１枚あたり約７秒で完了する。従って、１日約８〜１０時間の操業で平均４,０００〜５,０００枚の剥ぎ取り処理を行なうことができる。一連の剥ぎ取り作業のうち１回のフラッピングに約２秒かかるので、１枚の陰極板に対して何回もフラッピングが繰り返して行なわれると１日あたりの処理枚数が少なくなり、操業効率に影響することになる。   However, in the conventional stripping device, the base on which the cathode plate is placed is flat, so that the angle of the electrodeposited metal by the down-end when stripping the electrodeposited metal from the cathode plate is relative to the cathode plate. The maximum was 90 °, and the electrodeposited metal could not be completely removed in one operation. In that case, it was necessary to perform flapping once or a plurality of times. It is possible to peel the electrodeposited metal from the cathode plate by one or more flappings, but flapping means that extra time is taken and processing per hour is performed. There was a problem that the amount would decrease. Specifically, if stripping of the electrodeposited metal is completed without flapping, it is completed in about 7 seconds per sheet. Therefore, an average of 4,000 to 5,000 strips can be removed in an operation of about 8 to 10 hours per day. Since it takes about 2 seconds to flapping once in a series of stripping operations, the number of processed sheets per day is reduced if flapping is repeated several times on one cathode plate, and the operation efficiency is reduced. Will be affected.

そこで、本発明は、フラッピングを行なうことなく、フレキシング、チゼリング、ダウンエンダという陰極板から電着金属を剥ぎ取る際の一連の作業を１回で完了させることが可能な電着金属の剥取装置を提供することを目的とする。   Therefore, the present invention is a stripping of electrodeposited metal that can complete a series of operations when stripping the electrodeposited metal from the cathode plate such as flexing, chiseling, and down-ender without flapping. An object is to provide an apparatus.

上記課題を解決するために請求項１に記載の本発明は、電解製錬によってその表面に金属が電着した陰極板を起立させた状態で保持し、陰極板の両側を押圧することにより陰極板と電着金属との間に隙間を生じさせ、この隙間にチゼルを挿入することによって電着金属を引き剥がし、引き剥がした電着金属をさらにその底部を基点として横倒させることによって陰極板から電着金属を剥ぎ取る電着金属の剥取装置において、陰極板を載置する基台の両側に突起部を設け、この突起部に陰極板を横倒させながら引き剥がした電着金属の下部側表面を接触させることによって少なくとも電着金属の上縁部が突起部よりも下側に位置するに至るまで横倒させ、それによって電着金属を陰極板から分離するようにしたことを特徴とする。
電解が終了した陰極板を起立させた状態で基台上に保持し、陰極板の表面に析出した電着金属をその上部側から引き剥がし、そして、電着金属の底辺を基点として横倒させる。その際、基台の両側に設けられた突起部が電着金属の下部側の表面に接触するため、電着金属の上縁部はこの突起部よりも下側に位置する状態となるまで横倒させられる。このとき、基台の両側に設けられた突起部が「てこ」の働きをして陰極板と電着金属が上方に持ち上げられて両者は容易に分離される。これによって陰極板からの電着金属の剥ぎ取りがフレキシング、チゼリング、ダウンエンダという一連の作業で確実に行なわれるのでフラッピングを行なう必要がない。 In order to solve the above-mentioned problem, the present invention according to claim 1 is characterized in that a cathode plate electrodeposited with metal is held upright by electrolytic smelting, and the cathode is pressed by pressing both sides of the cathode plate. A cathode plate is created by creating a gap between the plate and the electrodeposited metal, peeling off the electrodeposited metal by inserting a chisel into the gap, and then laying the peeled electrodeposited metal upside down from the bottom. In the electrodeposition metal stripping device for stripping the electrodeposited metal from the electrodeposited metal, a projection is provided on both sides of the base on which the cathode plate is placed, and the electrodeposited metal peeled off while the cathode plate is lying sideways on the projection. By contacting the lower side surface, at least the upper edge portion of the electrodeposited metal is laid down until it is located below the protrusion, thereby separating the electrodeposited metal from the cathode plate. And
Hold the cathode plate after electrolysis upright on the base, peel off the electrodeposited metal deposited on the surface of the cathode plate from the upper side, and lay it sideways with the base of the electrodeposited metal as the starting point . At that time, since the protrusions provided on both sides of the base come into contact with the lower surface of the electrodeposited metal, the upper edge of the electrodeposited metal is laterally moved until it is positioned below the protrusion. Defeated. At this time, the protrusions provided on both sides of the base act as a “lever” and the cathode plate and the electrodeposited metal are lifted upward so that they are easily separated. As a result, stripping of the electrodeposited metal from the cathode plate is surely performed by a series of operations such as flexing, chiseling, and down-ender, so that it is not necessary to perform flapping.

上記課題を解決するために請求項２に記載の本発明は、請求項１に記載の電着金属の剥取装置において、電着金属の横倒時における陰極板との角度が少なくとも９０°を超え、９５°以下であることを特徴とする。
電着金属をダウンエンダにより横倒した時の角度は少なくとも９０°を超える角度から９５°の角度の範囲内とする。 In order to solve the above-mentioned problem, the present invention according to claim 2 is the electrodeposition metal stripping apparatus according to claim 1, wherein the angle with the cathode plate when the electrodeposited metal is overlaid is at least 90 °. More than 95 °.
The angle when the electrodeposited metal is laid down by the down-ender is at least in the range of more than 90 ° to 95 °.

上記課題を解決するために請求項３に記載の本発明は、請求項１又は２に記載の電着金属の剥取装置において、基台は半円筒形状とされていることを特徴とする。
基台を半円筒形状とすることで両側部に突起部を備えた基台を現出することができる。 In order to solve the above-mentioned problems, the present invention described in claim 3 is characterized in that, in the electrodeposited metal stripping apparatus described in claim 1 or 2, the base is formed in a semi-cylindrical shape.
By making the base a semi-cylindrical shape, a base having protrusions on both sides can be revealed.

本発明に係る電着金属の剥取装置によれば、基台の両側に突起部を設け、この突起部に陰極板から引き剥がされた電着金属の下部側表面を接触させることによって少なくとも電着金属の上縁部が突起部よりも下側に位置するに至るまで種板を横倒させるようにしたので、基台の両側に設けられた突起部が「てこ」のように働いて陰極板と電着金属を上方に持ち上げることとなり、フラッピングを行なうことなくフレキシング、チゼリング、ダウンエンダという一連の作業で確実に陰極板から電着金属を剥ぎ取ることができるという効果がある。
また、電着金属が剥ぎ取られた陰極板は繰り返し電解製錬に使用されるが、本発明に係る電着金属の剥取装置によれば、フレキシング、チゼリング、ダウンエンダという一連の作業で確実に電着金属を剥ぎ取ることができるので、陰極板の回転率が良くなり、１日あたりの処理量も増え、少なくとも毎月約３０ｔを超える増産が可能となるという効果がある。 According to the electrodeposited metal stripping apparatus of the present invention, at least the electrodeposition metal is provided by providing protrusions on both sides of the base and bringing the lower surface of the electrodeposited metal peeled off from the cathode plate into contact with the protrusions. Since the seed plate was laid sideways until the upper edge of the deposited metal was positioned below the protrusion, the protrusions on both sides of the base worked like a lever The plate and the electrodeposited metal are lifted upward, and there is an effect that the electrodeposited metal can be surely peeled off from the cathode plate by a series of operations such as flexing, chiseling and down-endering without flapping.
The cathode plate from which the electrodeposited metal has been stripped is repeatedly used for electrolytic smelting, but according to the electrodeposited metal stripping apparatus according to the present invention, the cathode plate can be reliably used in a series of operations such as flexing, chiseling, and down-ending. In addition, since the electrodeposited metal can be stripped, the rotation rate of the cathode plate is improved, the amount of processing per day is increased, and the production can be increased by at least about 30 t per month.

以下、本発明に係る電着金属の剥取装置について図面を参照しつつ詳細に説明する。図３は本発明に係る電着金属の剥取装置の一実施形態における正面図、図４はそのＡ−Ａ断面図、図５はＢ−Ｂ断面図である。
図である。 Hereinafter, an electrodeposited metal stripping apparatus according to the present invention will be described in detail with reference to the drawings. FIG. 3 is a front view of an electrodeposition metal stripping apparatus according to an embodiment of the present invention, FIG. 4 is an AA cross-sectional view thereof, and FIG. 5 is a BB cross-sectional view thereof.
FIG.

図示された電着金属の剥取装置１０は、概略として、床面Ｇに配置された架台１１上に立設された４本の支柱１２とそれらを水平方向に連結する横梁１３によってフレーム構造をなし、このフレームのほぼ中央に基台２０が配置され、この基台２０上に電着が終了した陰極板１を起立させた状態で載置するようになっている。また、基台２０の上方側には電着金属２の上部側面を両側から支持するホルダ３０が左右の両側に設けられている。また、図４の左右の両側にはリンク３２がフレームに軸止されると共に、その後端部が油圧シリンダ３２ａと連結されており、これによってリンク３２が揺動可能となっている。さらに、図３に示されているように、クロスバー４を左右から挟持するキャッチャ３１を備えている。これにより、陰極板１は基台２０上に起立した状態でしっかりと保持されることになる。   The electrodeposition metal stripping apparatus 10 shown in FIG. 1 roughly has a frame structure by four columns 12 erected on a gantry 11 arranged on a floor surface G and horizontal beams 13 connecting them in a horizontal direction. None, a base 20 is arranged in the approximate center of the frame, and the cathode plate 1 after electrodeposition is placed on the base 20 in an upright state. Moreover, the holder 30 which supports the upper side surface of the electrodeposited metal 2 from both sides is provided above the base 20 on both the left and right sides. In addition, links 32 are fixed to the frame on both the left and right sides in FIG. 4, and the rear ends thereof are connected to a hydraulic cylinder 32a, so that the links 32 can swing. Further, as shown in FIG. 3, a catcher 31 that holds the crossbar 4 from the left and right is provided. As a result, the cathode plate 1 is securely held in a standing state on the base 20.

また、陰極板１が載置されるその上方には、図４に示されているように、陰極板１の表面に析出した電着金属２と、陰極板１との間に挿入して陰極板１から電着金属２を引き剥がすチゼル３５が設けられている。チゼル３５は先端側にいくほど次第に鋭利に尖った断面略直角三角形の楔状をなし、これを電着金属２と陰極板１との間に挿入して下方に加圧押圧することで電着金属２の上端部側が基台２０を基点として拡開し、それによって電着金属２を陰極板１から引き剥がすようになっている。尚、チゼル３５は油圧シリンダ３５ａによって上下方向に可動されるようになっている。   Further, on the upper side of the cathode plate 1, as shown in FIG. 4, the cathode electrode 1 is inserted between the electrodeposited metal 2 deposited on the surface of the cathode plate 1 and the cathode plate 1. A chisel 35 for peeling the electrodeposited metal 2 from the plate 1 is provided. The chisel 35 has a wedge shape with a substantially right-angled triangle with a sharper point gradually toward the tip side. The chisel 35 is inserted between the electrodeposited metal 2 and the cathode plate 1 and pressed downward to press the electrodeposited metal. The upper end side of the base plate 2 is expanded with the base 20 as a base point, whereby the electrodeposited metal 2 is peeled off from the cathode plate 1. The chisel 35 is movable in the vertical direction by a hydraulic cylinder 35a.

ここで、陰極板１は、図示しない洗浄室で洗浄した後、フレキシングを行い、それをトラバースコンベア３８によって剥取装置１０へ移送してチゼリング、ダウンエンダを行なうようになっている。フレキシングは、図６（ｂ）に示すように、基台２０上に載置された陰極板1の左右に位置するようにして配置された押圧具３６によって陰極板１の側面を別々に押圧することにより行なわれる。尚、押圧具３６は、その後方に配置された図示しない油圧シリンダによって動作するようになっている。このように、陰極板１の側面を押圧具３６でそれぞれ別々に一度ずつ押圧することによって陰極板１と電着金属２の間に隙間を生じさせるフレキシングが行われる。そして、フレキシングが行なわれた陰極板１はトラバースコンベア３８によって剥取装置１０の剥取位置へ搬送される。
剥取装置１０には、図４に示されているように、基台２０上に載置された陰極板１の左右の両側に位置するようにしてガイドプレート３７ｃが配置されており、ガイドプレート３７ｃには電着金属２の側面近傍位置から伸びる円弧状のレール３７が設けられている。ガイドプレート３７ｃには上述したチゼル３５によって陰極板１から引き剥がされた左右の電着金属２を両側からそれぞれ保持してダウンエンダ又はフラッピングさせる左右のグリップ３７を備えている。グリップ３７は、油圧シリンダ３７ａによって電着金属２の側面近傍位置から伸びる円弧状のレール３７ｂ上を移動可能とされている。また、ガイドプレート３７ｃは、下部側に配置された油圧シリンダ３７ｄにより陰極板１側に傾倒するようになっている。 Here, the cathode plate 1 is cleaned in a cleaning chamber (not shown), then flexed, and transferred to the stripping device 10 by a traverse conveyor 38 for chiseling and down-end. As shown in FIG. 6B, the flexing is performed by separately pressing the side surfaces of the cathode plate 1 by pressing tools 36 arranged so as to be positioned on the left and right sides of the cathode plate 1 placed on the base 20. It is done by doing. The pressing tool 36 is operated by a hydraulic cylinder (not shown) disposed behind the pressing tool 36. In this way, flexing is performed in which a gap is generated between the cathode plate 1 and the electrodeposited metal 2 by pressing the side surfaces of the cathode plate 1 separately with the pressing tool 36 one by one. Then, the flexed cathode plate 1 is conveyed to the peeling position of the peeling device 10 by the traverse conveyor 38.
As shown in FIG. 4, guide plates 37 c are arranged in the stripping device 10 so as to be positioned on both the left and right sides of the cathode plate 1 placed on the base 20. An arc-shaped rail 37 extending from the position in the vicinity of the side surface of the electrodeposited metal 2 is provided at 37c. The guide plate 37c is provided with left and right grips 37 for holding the left and right electrodeposited metals 2 peeled off from the cathode plate 1 by the chisel 35 from the both sides and down-ending or flapping. The grip 37 can be moved on an arc-shaped rail 37b extending from a position near the side surface of the electrodeposited metal 2 by a hydraulic cylinder 37a. The guide plate 37c is inclined to the cathode plate 1 side by a hydraulic cylinder 37d arranged on the lower side.

剥取装置１０は上述のような構成を備えているが、本剥取装置１０の最も特徴的なところは基台２０の形状にある。すなわち、図４に示されているように、基台２０は、その両側にそれぞれ突起部２１が設けられており、チゼル３５によって陰極板１から引き剥がされた電着金属２をグリップ３７によって横倒させるに際して電着金属２の下部側表面を突起部２１に接触させることによって少なくとも電着金属２の上縁部が突起部２１よりも下側に位置するに至るまで電着金属２を横倒することができるようになっている。この点について、電着金属２の剥ぎ取りを模式的に示した図６を用いてさらに詳しく説明する。まず、図６（ａ）に示すように、電着の終了し洗浄が行なわれた陰極板１をトラバースコンベア３８に起立させた状態で載置する。   The stripping device 10 has the above-described configuration, but the most characteristic part of the stripping device 10 is the shape of the base 20. That is, as shown in FIG. 4, the base 20 is provided with protrusions 21 on both sides thereof, and the electrodeposited metal 2 peeled off from the cathode plate 1 by the chisel 35 is laterally moved by the grip 37. When the electrodeposition metal 2 is tilted, the electrodeposited metal 2 is laid sideways until at least the upper edge of the electrodeposited metal 2 is positioned below the protrusion 21 by bringing the lower surface of the electrodeposited metal 2 into contact with the protrusion 21. Can be done. This point will be described in more detail with reference to FIG. 6 schematically showing the stripping of the electrodeposited metal 2. First, as shown in FIG. 6A, the cathode plate 1 that has been electrodeposited and cleaned is placed on the traverse conveyor 38 in a standing state.

そして、陰極板１の表面を両側からそれぞれ別々に押圧してフレキシングを行ない（図６（ｂ））。陰極板１と電着金属２との間に隙間を生じさせる。フレキシングによって頂部に隙間が生じたら、トラバースコンベア３８で剥取装置１０の剥取位置に移送する。そして、フレキシングにより生じた隙間にチゼル３５を挿入し、一気に押し下げることによって電着金属２をその基台２０に載置されている底部を基点として上縁部側を拡開するようにして引き剥がす（図６（ｃ））。引き剥がされた電着金属２にグリップ３７を装着してさらに横倒させると、基台２０の両側に設けられた突起部２１が電着金属２の下部側の表面に接触し、電着金属２の上縁部はこの突起部２１よりも下側に位置する状態となるまで横倒させられる（図６（ｄ））。このとき、基台２０の両側に設けた突起部２１が「てこ」の働きをして陰極板１と電着金属２の底部が上方に持ち上げられる。この動作によって電着金属２は陰極板１から容易に分離されることとなり、フラッピングを行なうことなくフレキシング、チゼリング、ダウンエンダという一連の作業で陰極板１から電着金属２を確実に剥ぎ取ることが可能となる。   Then, flexing is performed by pressing the surface of the cathode plate 1 separately from both sides (FIG. 6B). A gap is generated between the cathode plate 1 and the electrodeposited metal 2. When a gap is generated at the top due to flexing, the traverse conveyor 38 transfers the stripping device 10 to the stripping position. Then, the chisel 35 is inserted into the gap generated by the flexing and is pushed down at a stretch to pull the electrodeposited metal 2 so as to expand the upper edge side with the bottom part placed on the base 20 as a base point. Peel off (FIG. 6C). When the grip 37 is attached to the peeled electrodeposited metal 2 and further tilted sideways, the protrusions 21 provided on both sides of the base 20 come into contact with the lower surface of the electrodeposited metal 2, and the electrodeposited metal The upper edge of 2 is laid down until it is in a state of being located below the protrusion 21 (FIG. 6D). At this time, the protrusions 21 provided on both sides of the base 20 act as a lever, and the bottoms of the cathode plate 1 and the electrodeposited metal 2 are lifted upward. By this operation, the electrodeposited metal 2 is easily separated from the cathode plate 1, and the electrodeposited metal 2 is surely peeled off from the cathode plate 1 by a series of operations such as flexing, chiseling and down-end without flapping. It becomes possible.

ここで、電着金属２を横倒させたときの電着金属２と陰極板１とのなす角度θは、少なくとも９０°を超え、９５°以下であることが好ましい。９０°より小さい角度であると基台の突起部による「てこ」の作用が十分に発揮されず、９５°よりも大きいと電着金属２が歪むおそれがあるからである。
また、基台２０の形状は図７（ａ）に示すような平板の両側部に山形の突起部２１を備えたものでもよいが、図７（ｂ）に示すような半円筒形状とすることもできる。半円筒形状とすることで両側部に突起部２１を備えた基台２０を容易に現出することができる。突起部の高さは５〜３０ｍｍ程度、好ましくは８〜１０ｍｍ程度の範囲であるとよい。 Here, the angle θ formed between the electrodeposited metal 2 and the cathode plate 1 when the electrodeposited metal 2 is laid down is preferably at least more than 90 ° and not more than 95 °. This is because if the angle is smaller than 90 °, the “lever” action by the protrusions of the base is not sufficiently exhibited, and if it is larger than 95 °, the electrodeposited metal 2 may be distorted.
Further, the shape of the base 20 may be provided with a mountain-shaped protrusion 21 on both sides of a flat plate as shown in FIG. 7A, but it is a semi-cylindrical shape as shown in FIG. 7B. You can also. By making it a semi-cylindrical shape, the base 20 provided with the protrusions 21 on both sides can be easily revealed. The height of the protrusion is about 5 to 30 mm, preferably about 8 to 10 mm.

以上のように、本発明に係る電着金属の剥取装置によれば、フラッピングを行なうことなくフレキシング、チゼリング、ダウンエンダという一連の作業で確実に陰極板１から電着金属２を剥ぎ取ることができる。さらに電着金属２が剥ぎ取られた陰極板１を再び電解製錬に供するまでの時間も短縮されるので陰極板１の回転率が良くなり、１日あたりの処理量アップに貢献する。   As described above, the electrodeposited metal stripping apparatus according to the present invention reliably strips the electrodeposited metal 2 from the cathode plate 1 through a series of operations such as flexing, chiseling, and down-end without flapping. be able to. Furthermore, since the time until the cathode plate 1 from which the electrodeposited metal 2 has been stripped is again subjected to electrolytic smelting is shortened, the rate of rotation of the cathode plate 1 is improved, contributing to an increase in throughput per day.
