Description

本発明は電解精製された金属板の洗浄装置に関する。   The present invention relates to a cleaning apparatus for electrolytically purified metal plates.

一般に銅、ニッケルなどの電解精製においては、それぞれ精製目的の金属製アノード及びカソードとをクレーンによって電解槽中に交互に吊るし、該カソードに目的金属を電着させることにより製品を得ている。   In general, in electrolytic refining of copper, nickel, etc., products are obtained by suspending metal anodes and cathodes for purification purposes alternately in an electrolytic cell by a crane and electrodepositing the target metal on the cathodes.

電解精製によって製造された金属板は、クレーンによって電解槽から引き上げられ、洗浄装置に搬送され、表面に残存する電解液を回収するために、及び製品の汚染を防ぐために、酸あるいは水などの洗浄液により洗浄されている。   The metal plate produced by electrolytic refining is lifted from the electrolytic cell by a crane, transported to a cleaning device, and recovered in order to recover the electrolytic solution remaining on the surface and to prevent contamination of the product, a cleaning solution such as acid or water It is washed by.

洗浄後の金属板は結束工程に送られ、所定枚数にまとめられ、出荷、あるいは保管されるが、例えば特許文献１（実公昭５３−８０１１号公報）に公開されているとおり、洗浄工程と結束工程は一連の工程として連続して行われる場合が多い。この際、操業効率を向上させるため、また、後工程の結束工程において結束しやすくするために、電解精製後の金属板を重なり方向に整列させて洗浄工程の洗浄装置に装入するのが一般的である。   The metal plate after washing is sent to the bundling process, collected into a predetermined number, shipped, or stored. For example, as disclosed in Patent Document 1 (Japanese Utility Model Publication No. 53-8011), the cleaning process and bundling are performed. The process is often performed continuously as a series of processes. At this time, in order to improve the operation efficiency and facilitate bundling in the bundling process in the subsequent process, it is common to place the metal plates after electrolytic purification in the overlapping direction so as to be loaded into the cleaning apparatus in the cleaning process. Is.

図１は、従来の金属板の洗浄装置の概要図であり、図１（ａ）は従来の金属板の洗浄装置を側面から見た図、図１（ｂ）は従来の金属板の洗浄装置を正面から見た図である。金属板１は、複数のカソード１ａを電解槽中に平行な状態で吊るし、カソード１ａの金属製薄板１ｂの電着面に電解精製により目的金属を電着させて製造する。なお、カソード１ａは、電着面となる金属製薄板１ｂと、金属製薄板１ｂを支持する金属製のビーム１３と、金属製薄板１ｂと同種の金属製で金属製薄板１ｂと金属製のビーム１３とをつなぐ吊手５とから構成される。製造された金属板１は、クレーンによって、カソード１ａとともに電解槽から引き上げられ、洗浄装置に搬送される。   FIG. 1 is a schematic diagram of a conventional metal plate cleaning apparatus, FIG. 1 (a) is a side view of the conventional metal plate cleaning apparatus, and FIG. 1 (b) is a conventional metal plate cleaning apparatus. It is the figure which looked at from the front. The metal plate 1 is manufactured by suspending a plurality of cathodes 1a in parallel in an electrolytic cell, and electrodepositing a target metal on the electrodeposition surface of the metal thin plate 1b of the cathode 1a by electrolytic purification. The cathode 1a includes a metal thin plate 1b serving as an electrodeposition surface, a metal beam 13 that supports the metal thin plate 1b, and the same type of metal as the metal thin plate 1b, the metal thin plate 1b and the metal beam. 13 and a suspension 5 that connects 13. The manufactured metal plate 1 is pulled up from the electrolytic cell together with the cathode 1a by a crane, and is conveyed to a cleaning device.

電解精製後の金属板１は、重なり方向に整列した状態で、カソード１ａとともに搬送方向２に搬送され、洗浄装置による洗浄工程、図示しない乾燥工程、図示しない結束工程へ順に移動する。洗浄工程で洗浄装置の洗浄位置に装入された金属板１は、その搬送過程で、洗浄装置内に配置された多数の洗浄ノズル３及び洗浄液配管４により洗浄液を噴霧され、洗浄される。次に、金属板１は、カソード１ａとともに図示しない乾燥工程において乾燥処理された後、搬送方向２に進み、図示しない結束工程において所定枚数にまとめられ結束される。   After the electrolytic purification, the metal plate 1 is transported in the transport direction 2 together with the cathode 1a in a state of being aligned in the overlapping direction, and sequentially moves to a cleaning process by a cleaning device, a drying process (not shown), and a bundling process (not shown). The metal plate 1 inserted into the cleaning position of the cleaning device in the cleaning process is cleaned by spraying the cleaning liquid by the multiple cleaning nozzles 3 and the cleaning liquid pipes 4 arranged in the cleaning device during the transport process. Next, the metal plate 1 is dried in a drying process (not shown) together with the cathode 1a, then proceeds in the transport direction 2, and is bundled and bundled into a predetermined number in a bundling process (not shown).

ところが、従来の金属板の洗浄装置の問題点として、吊手５の近傍における洗浄不足による不具合の発生が知られている。この洗浄不足が発生すると、洗浄不足により残存した電解液成分が乾燥時に結晶として金属板１に付着し、製品である金属板１を汚染することになり、金属板１の品位、外観上の品質不具合につながる。このため、洗浄不足の不具合を解消することは洗浄工程において重要である。   However, as a problem of the conventional metal plate cleaning apparatus, it is known that a defect due to insufficient cleaning in the vicinity of the suspension 5 occurs. When this lack of cleaning occurs, the electrolyte component remaining due to the lack of cleaning adheres to the metal plate 1 as crystals during drying, and contaminates the metal plate 1 as a product, and the quality and quality of the metal plate 1 are improved. It leads to a malfunction. For this reason, it is important in the cleaning process to solve the problem of insufficient cleaning.

図２は、カソード１ａの吊手５付近の拡大図である。図２に示すように、吊手５と金属板１との接合部の内側には、ポケット状部位６が形成される。カソード１ａを電解槽中に吊るした際にポケット状部位６に入り込んだ電解液は、電解精製した金属板１を電解槽から引き上げた後も、この部位に留まって流れ落ちずに残存する。この部位に残存した電解液は、従来の金属板の洗浄装置では効率的に取り除くことが困難であるため、上記の洗浄不足が発生していた。   FIG. 2 is an enlarged view of the vicinity of the handle 5 of the cathode 1a. As shown in FIG. 2, a pocket-shaped portion 6 is formed on the inner side of the joint portion between the handle 5 and the metal plate 1. The electrolytic solution that has entered the pocket-shaped portion 6 when the cathode 1a is suspended in the electrolytic cell remains in this region and does not flow down after the electrolytically purified metal plate 1 is pulled up from the electrolytic cell. The electrolyte remaining in this region is difficult to remove efficiently with a conventional metal plate cleaning apparatus, and thus the above-described insufficient cleaning has occurred.

ポケット状部位６に残存した電解液を効率的に取り除くためには、図１に示す洗浄ノズル３及び洗浄液配管４を、吊手５のポケット状部位６の内側に向けて吊手５に近接して配置すればよい。しかし、そうすると、金属板１の移動空間内に洗浄ノズル３及び洗浄液配管４を設置しなければならず、洗浄ノズル３が金属板１の移動を妨げる結果となるため、従来の洗浄装置では、洗浄ノズル３を吊手５に近接して配置することができなかった。このため、従来の洗浄装置では、洗浄ノズル３から噴霧される洗浄液を吊手５の側方からポケット状部位６の内側まで直接到達させることができず、ポケット状部位６を十分に洗浄することができなかった。   In order to efficiently remove the electrolyte remaining in the pocket-shaped part 6, the cleaning nozzle 3 and the cleaning liquid pipe 4 shown in FIG. 1 are brought close to the hook 5 toward the inside of the pocket-shaped part 6 of the hook 5. Can be arranged. However, in that case, the cleaning nozzle 3 and the cleaning liquid pipe 4 must be installed in the moving space of the metal plate 1, which results in the cleaning nozzle 3 hindering the movement of the metal plate 1. Nozzle 3 could not be placed close to the hanger 5. For this reason, in the conventional cleaning apparatus, the cleaning liquid sprayed from the cleaning nozzle 3 cannot reach the inside of the pocket-shaped part 6 from the side of the handle 5 and the pocket-shaped part 6 is sufficiently cleaned. I could not.

一方、例えば、特許文献２（特開平１１−９２９８６号公報）には、電気銅表面を充分に洗浄するための電気銅洗浄装置が開示されている。この装置では、洗浄工程前に重ねて整列させていた電気銅を、洗浄工程において、通常の搬送方向（重なり方向）に対して横向きに１枚ずつ抜き出して移動させ、一枚ずつ洗浄装置に装入して洗浄し、結束工程に搬送する際に改めて重ねて整列させる方法を採用している。しかし、その方法では、金属板が重なり方向に整列した状態で洗浄する従来の方法に比べ、大きなスペースを必要とし、コスト的に不利になるだけでなく、洗浄装置内に配置された洗浄ノズル及び洗浄液配管は固定されて電気銅の移動を妨げないような配置となっているため、特許文献２の技術を応用して、前記の不具合を解決しょうとしても、図２に示すポケット状部位６の開口部側からポケット状部位６の内側へ洗浄液を噴霧することができず、上記の問題点の根本的な解決策とはならない。
実公昭５３−８０１１号公報 特開平１１−９２９８６号公報 On the other hand, for example, Patent Document 2 (Japanese Patent Laid-Open No. 11-92986) discloses an electrolytic copper cleaning apparatus for sufficiently cleaning the electrolytic copper surface. In this apparatus, the electrolytic copper that has been stacked and aligned before the cleaning process is extracted and moved one by one in a direction transverse to the normal transport direction (overlapping direction) in the cleaning process, and loaded into the cleaning apparatus one by one. A method is adopted in which they are put in, washed, and stacked again when transported to the bundling process. However, this method requires a large space and is not disadvantageous in cost as compared with the conventional method in which the metal plates are cleaned in a state in which the metal plates are aligned in the overlapping direction, and the cleaning nozzle disposed in the cleaning apparatus and Since the cleaning liquid piping is fixed and does not hinder the movement of the electrolytic copper, even if the technique of Patent Document 2 is applied to solve the above-mentioned problem, the pocket-shaped portion 6 shown in FIG. The cleaning liquid cannot be sprayed from the opening side to the inside of the pocket-shaped part 6, which does not constitute a fundamental solution to the above problem.

On the other hand, when the cleaning nozzle is disposed close to the pocket portion of the hand, the support portion of the cleaning nozzle and the piping system obstruct the beam movement path when the metal plate is transported. Therefore, the present inventors have arranged the cleaning nozzle toward the inside of the pocket portion of the hand of the hand and in proximity to the hand of the hand, and by making the cleaning nozzle that has been conventionally fixed movable, The present invention was completed by taking measures not to obstruct the movement path.

The cathode (1a) is made of a metal of the same type as that of the cathode (1a) and includes a suspension (5) connecting the metal thin plate (1b) and the metal beam (13). The electrode plate of the thin plate (1b) is electrodeposited with a target metal, and the metal plate (1) is electrolytically purified. In the process of transporting the electrolytically purified metal plate (1), a number of cleaning nozzles ( 9) Supplying the cleaning liquid from the main pipe (7) to the metal plate (1) and spraying the cleaning liquid toward the metal plate (1), so that the metal plate (1) is cleaned. The cleaning nozzle (9) that faces the inside of the suspension (5) is close to the space through which the suspension (5) passes The cleaning nozzle (9) is attached to the main pipe (7) so as to be movable, and the cleaning liquid sprayed from the cleaning nozzle (9) is applied to the hand from the side of the hand (5). 5), and the relative position of the cleaning nozzle (9) with respect to the suspension (5) is changed by the contact between the cleaning nozzle (9) and the moving beam (13). 9) is automatically moved to the retracted position.

請求項２の発明は、該洗浄ノズル（９）を支持する可動配管（１０）と主配管（７）との連結部において、可動配管（１０）を主配管（７）に対して可動式のジョイント（８）により回動可能に取り付けている。   According to the second aspect of the present invention, the movable pipe (10) is movable with respect to the main pipe (7) at the connecting portion between the movable pipe (10) and the main pipe (7) supporting the cleaning nozzle (9). The joint (8) is pivotably attached.

請求項３の発明は、可動配管（１０）と主配管（７）との連結部以外の他の部分において、該洗浄ノズル（９）を主配管（７）に対して可動式のジョイント（８）により回動可能に取り付けている。   According to the third aspect of the present invention, the cleaning nozzle (9) is connected to the main pipe (7) with a movable joint (8) at a portion other than the connecting portion between the movable pipe (10) and the main pipe (7). ) So that it can rotate.

請求項１の発明によると、金属板（１）の洗浄を行う洗浄装置において、吊手（５）に対応する該洗浄ノズル（９）を該吊手（５）の内側に向けて該吊手（５）の通過する空間に近接して配置することにより、洗浄ノズル（９）から噴霧される洗浄液を該吊手（５）の側方から該吊手（５）の内側へ直接到達させるから、吊手（５）と金属板（１）との接合部の内側に形成されるポケット状部位（６）に残存する電解液を効率的に除去し、金属板（１）の品質を向上させることができ、その工業的価値は極めて大きい。また、該洗浄ノズル（９）を主配管（７）に対して可動式として取り付け、可動式の洗浄ノズル（９）と移動中のビーム（１３）との接触によって該洗浄ノズル（９）の該吊手（５）に対する相対位置を変え、該洗浄ノズル（９）を自動的に退避位置に移動させるから、該洗浄ノズル（９）を吊手（５）のポケット状部位（６）に近接させて配置しても、金属板（１）の搬送の妨げとなることがない。さらに、ビーム（１３）の移動を利用したから、可動式の洗浄ノズル（９）の退避位置への移動のために、別途駆動源を必要とせず、簡単な機構で洗浄ノズル（９）を可動式として構成できる。   According to the invention of claim 1, in the cleaning apparatus for cleaning the metal plate (1), the cleaning nozzle (9) corresponding to the suspension (5) is directed toward the inside of the suspension (5). By arranging it close to the space through which (5) passes, the cleaning liquid sprayed from the cleaning nozzle (9) is directly reached from the side of the hand (5) to the inside of the hand (5). The electrolytic solution remaining in the pocket-shaped part (6) formed inside the joint between the hand (5) and the metal plate (1) is efficiently removed, and the quality of the metal plate (1) is improved. And its industrial value is extremely large. Further, the cleaning nozzle (9) is attached to the main pipe (7) as a movable type, and the cleaning nozzle (9) is contacted by the movable cleaning nozzle (9) and the moving beam (13). Since the cleaning nozzle (9) is automatically moved to the retracted position by changing the relative position with respect to the suspension (5), the cleaning nozzle (9) is brought close to the pocket-shaped part (6) of the suspension (5). Even if it arrange | positions, it will not become a hindrance to conveyance of a metal plate (1). Further, since the movement of the beam (13) is used, the cleaning nozzle (9) can be moved by a simple mechanism without requiring a separate drive source for moving the movable cleaning nozzle (9) to the retracted position. Can be configured as an expression.

請求項２の発明によると、可動式の洗浄ノズル（９）を支持する可動配管（１０）を可動配管（１０）と主配管（７）との連結部において可動式のジョイント（８）により回動可能に取り付け、ジョイント（８）に連結機能と可動機能を併せ持たせることにより、省スペース化を図ることができ、スペースの存在により設計の自由度が高まる。   According to the invention of claim 2, the movable pipe (10) supporting the movable washing nozzle (9) is rotated by the movable joint (8) at the connecting portion between the movable pipe (10) and the main pipe (7). By movably attaching the joint (8) to the joint function and the movable function, it is possible to save space and increase the degree of design freedom due to the existence of the space.

請求項３の発明によると、可動式の洗浄ノズル（９）を主配管（７）に対して可動配管（１０）と主配管（７）の連結部以外の他の部分において可動式のジョイント（８）により回動可能に取り付けているので、主配管（７）と可動配管（１０）の連結部と、ジョイント（８）の可動部とを分散することにより、機械の構造を簡単化できる。   According to the invention of claim 3, the movable cleaning nozzle (9) is connected to the main pipe (7) at a movable joint (10) at a portion other than the connecting part of the main pipe (7) ( 8), the structure of the machine can be simplified by dispersing the connecting part of the main pipe (7) and the movable pipe (10) and the movable part of the joint (8).

本発明の電解精製された金属板の洗浄装置は、図１の従来の洗浄装置と同様に、電解精製した金属板１の搬送過程で、洗浄位置に配置した多数の洗浄ノズル３に主配管７から洗浄液を供給して、金属板１に向けて洗浄液を噴霧することにより、金属板１の洗浄を行う。カソード１ａも、従来例のものと同様であり、電着面となる金属製薄板１ｂと、金属製薄板１ｂを支持する金属製のビーム１３と、金属製薄板１ｂと同種の金属製で該金属製薄板１ｂと金属製のビーム１３とをつなぐ吊手５とから構成される。   The cleaning apparatus for electrolytically purified metal plates of the present invention is similar to the conventional cleaning apparatus of FIG. 1 in that a main pipe 7 is connected to a large number of cleaning nozzles 3 arranged at a cleaning position in the process of transporting the electrolytically purified metal plate 1. The metal plate 1 is cleaned by supplying a cleaning solution and spraying the cleaning solution toward the metal plate 1. The cathode 1a is also similar to the conventional example, and is made of a metal thin plate 1b serving as an electrodeposition surface, a metal beam 13 supporting the metal thin plate 1b, and the same type of metal as the metal thin plate 1b. The suspension plate 5 includes a suspension 5 that connects the thin plate 1 b and the metal beam 13.

そして、本発明の電解精製された金属板の洗浄装置は、多数の洗浄ノズル３の他に、特徴的な構成として、吊手５の内側部分、つまりポケット状部位６に残存する電解液を確実に除去するために、左右の吊手５に対向して、可動式の洗浄ノズル９を備えている。   In addition to the large number of cleaning nozzles 3, the electrolytically cleaned metal plate cleaning apparatus of the present invention has a characteristic configuration in which the electrolyte remaining in the inner portion of the suspension 5, that is, in the pocket-shaped portion 6 is ensured. In order to remove them, a movable cleaning nozzle 9 is provided opposite to the left and right hanging handles 5.

図３は、本発明の金属板の洗浄装置において、可動式の洗浄ノズル９の部分を示しており、図３（ａ）は金属板１の搬送方向２に対して側面から見た図であり、図３（ｂ）は金属板１の搬送方向２に対して正面から見た図である。   FIG. 3 shows a part of the movable cleaning nozzle 9 in the metal plate cleaning apparatus of the present invention, and FIG. 3A is a view seen from the side with respect to the conveying direction 2 of the metal plate 1. FIG. 3B is a view seen from the front with respect to the conveying direction 2 of the metal plate 1.

可動式の洗浄ノズル９は、吊手５の内側のポケット状部位６に向けて吊手５の通過する空間に近接して配置され、主配管７に対して連結部で可動式として取り付けられる（請求項１）。   The movable cleaning nozzle 9 is disposed close to the space through which the suspension 5 passes toward the pocket-shaped portion 6 inside the suspension 5 and is attached to the main pipe 7 as a movable portion at the connecting portion ( Claim 1).

具体的には、可動式の洗浄ノズル９は、これを支持する可動配管１０と、主配管７の分岐部７ａとの連結部において可動式のジョイント８により回動可能に取り付けられる（請求項２）。この取付け状態で、可動式の洗浄ノズル９の噴霧口は、吊手５の側方、つまりポケット状部位６の開口部側に向けられている。   Specifically, the movable cleaning nozzle 9 is rotatably attached by a movable joint 8 at a connecting portion between the movable pipe 10 that supports the movable cleaning nozzle 9 and the branch portion 7a of the main pipe 7 (claim 2). ). In this attached state, the spray port of the movable cleaning nozzle 9 is directed to the side of the suspension 5, that is, to the opening side of the pocket-shaped part 6.

なお、洗浄ノズル９は、図３のように、可動配管１０と、主配管の分岐部７ａとの連結部において可動式のジョイント８により回動可能に取り付けられるが、可動式のジョイント８は、可動配管１０と主配管７（主配管７は分岐部７ａを含む。）の連結部以外の他の部分、例えば分岐部７ａの途中に設けてもよく、また分岐部７ａと主配管７との分岐部分に設けることもできる（請求項３）。   As shown in FIG. 3, the cleaning nozzle 9 is rotatably attached by a movable joint 8 at a connecting portion between the movable pipe 10 and the branching portion 7a of the main pipe. The movable pipe 10 and the main pipe 7 (the main pipe 7 includes the branch portion 7a) may be provided in a portion other than the connecting portion, for example, in the middle of the branch portion 7a, or between the branch portion 7a and the main pipe 7 It can also be provided at the branching portion (claim 3).

このような構成によって、可動式の洗浄ノズル９及び可動配管１０は、可動式のジョイント８を回転中心として、図３（ａ）に示した回動範囲１１でスイングする機能を有している。ここで、ジョイント８の回転軸は、ビーム１３の長手方向と平行である。なお、洗浄ノズル９は、図３（ｂ）に示すように、洗浄ノズル９の前を金属板１が通過する際に、吊手５のポケット状部位６に到達する範囲（洗浄液噴霧範囲１２）に洗浄液を噴霧するように位置調整してあり、洗浄液の噴射圧もそれに適合するように調整してある。   With such a configuration, the movable cleaning nozzle 9 and the movable pipe 10 have a function of swinging in the rotation range 11 shown in FIG. 3A with the movable joint 8 as the rotation center. Here, the rotation axis of the joint 8 is parallel to the longitudinal direction of the beam 13. In addition, as shown in FIG.3 (b), when the metal plate 1 passes the front of the cleaning nozzle 9, the cleaning nozzle 9 reaches the pocket-shaped part 6 of the hanger 5 (cleaning liquid spraying range 12). The position is adjusted so that the cleaning liquid is sprayed, and the spraying pressure of the cleaning liquid is also adjusted so as to match it.

本発明においても、図１の従来の金属板の洗浄装置と同様に、電解精製後の金属板１は重なり方向に整列した状態で、搬送方向２に移動して、本発明の洗浄装置内に装入され、その搬送過程で、洗浄装置内に配置された図示しない多数の固定式の洗浄ノズル３および本発明の要部としての可動式の洗浄ノズル９によって洗浄液を噴霧され、洗浄される。洗浄ノズル９は、主配管７から洗浄液の供給をうける。このようにして、洗浄ノズル９から噴霧される洗浄液は、吊手５の側方から吊手５のポケット状部位６の内側へ直接到達し、ポケット状部位６に残存する電解液を効率的に除去できるようになる。   Also in the present invention, like the conventional metal plate cleaning apparatus of FIG. 1, the metal plate 1 after electrolytic purification is moved in the conveying direction 2 in the state of being aligned in the overlapping direction, and is moved into the cleaning apparatus of the present invention. In the transfer process, the cleaning liquid is sprayed and cleaned by a large number of fixed cleaning nozzles 3 (not shown) arranged in the cleaning device and a movable cleaning nozzle 9 as a main part of the present invention. The cleaning nozzle 9 is supplied with a cleaning liquid from the main pipe 7. In this way, the cleaning liquid sprayed from the cleaning nozzle 9 directly reaches the inside of the pocket-shaped part 6 of the hand 5 from the side of the hand 5 and efficiently removes the electrolyte remaining in the pocket-shaped part 6. Can be removed.

図４は、可動式の洗浄ノズルの動作を説明する概念図である。図４において、（ａ）〜（ｈ）はそれぞれ、金属板１が搬送方向２に向かって順次移動する際の、洗浄ノズル９、可動配管１０及び洗浄液の噴霧範囲１２と、金属板１、吊手５及びビーム１３との相対的な位置関係の変化を（ａ）→（ｈ）の順に示している。   FIG. 4 is a conceptual diagram for explaining the operation of the movable cleaning nozzle. 4, (a) to (h) respectively show the cleaning nozzle 9, the movable pipe 10, and the spray range 12 of the cleaning liquid, the metal plate 1, and the suspension when the metal plate 1 sequentially moves in the transport direction 2. Changes in the relative positional relationship between the hand 5 and the beam 13 are shown in the order of (a) → (h).

ビーム１３と吊手５により吊るされた金属板１は、図４（ａ）のように、搬送方向２へ移動し、洗浄液噴霧範囲１２に入る。なお、この状態で、洗浄ノズル９及び可動配管１０は、自然に懸垂された状態となっている。この状態からさらに、金属板１が搬送方向２へ移動すると、図４（ｂ）のように可動配管１０にビーム１３が接触する。この状態で、洗浄ノズル９は吊手５のポケット状部位６の開口部に最も近接し、洗浄ノズル９から噴出された洗浄液は、ポケット状部位６の開口部のほぼ正面から直接ポケット状部位６の内部へ到達し、ポケット状部位６内部に残存する電解液を外へ押し流す。   The metal plate 1 hung by the beam 13 and the hanger 5 moves in the transport direction 2 and enters the cleaning liquid spray range 12 as shown in FIG. In this state, the cleaning nozzle 9 and the movable pipe 10 are naturally suspended. When the metal plate 1 is further moved in the transport direction 2 from this state, the beam 13 comes into contact with the movable pipe 10 as shown in FIG. In this state, the cleaning nozzle 9 is closest to the opening of the pocket-shaped part 6 of the hand 5, and the cleaning liquid ejected from the cleaning nozzle 9 is directly from the front of the opening of the pocket-shaped part 6 directly to the pocket-shaped part 6. The electrolyte solution remaining inside the pocket-shaped part 6 is pushed out.

図４（ｃ）〜（ｇ）は、金属板１の搬送につれて、ビーム１３が洗浄ノズル９及び可動配管１０を押し上げて、支えながら移動する過程を示している。このように、ビーム１３は、金属板１の搬送につれて、洗浄ノズル９及び可動配管１０を押し上げて、洗浄ノズル９の吊手５に対する相対位置を変え、洗浄ノズル９を自動的に退避位置に移動させる。このため、洗浄ノズル９を吊手５のポケット状部位６に近接させて配置しても、金属板１の搬送の妨げとなることがない。   4C to 4G show a process in which the beam 13 pushes the cleaning nozzle 9 and the movable pipe 10 and moves while supporting the metal plate 1 as it is conveyed. In this way, the beam 13 pushes up the cleaning nozzle 9 and the movable pipe 10 as the metal plate 1 is conveyed, changes the relative position of the cleaning nozzle 9 with respect to the handle 5, and automatically moves the cleaning nozzle 9 to the retracted position. Let For this reason, even if the cleaning nozzle 9 is arranged close to the pocket-like portion 6 of the hand 5, it does not hinder the conveyance of the metal plate 1.

図４（ｇ）のように、ビーム１３が洗浄ノズル９の下を通過すると、洗浄ノズル９はビーム１３の支えを失って、可動配管１０とともにスイングして自然に懸垂された状態に戻る。図４（ｈ）は、金属板１が通過した後、洗浄ノズル９が図示しない次の金属板１に対して図４（ａ）と同様な状態になっていることを示している。   As shown in FIG. 4G, when the beam 13 passes under the cleaning nozzle 9, the cleaning nozzle 9 loses the support of the beam 13, swings together with the movable pipe 10, and returns to the state of being suspended naturally. FIG. 4 (h) shows that after the metal plate 1 passes, the cleaning nozzle 9 is in the same state as FIG. 4 (a) with respect to the next metal plate 1 (not shown).

以上の通り、本発明の洗浄装置によれば、従来通り重なり方向に整列している金属板１の状況を変えることなく、吊手５のポケット状部位６に残存する電解液を効率よく洗浄することができる。   As described above, according to the cleaning apparatus of the present invention, the electrolytic solution remaining in the pocket-shaped portion 6 of the suspension 5 is efficiently cleaned without changing the state of the metal plates 1 aligned in the overlapping direction as in the past. be able to.

なお、可動配管１０の形状を装置の側面、つまりビーム１３の長手方向から見て、例えばＬ字状とし、搬送方向２の逆方向に洗浄ノズル９を後退させておけば、ビーム１３が可動配管１０に当たる前に、洗浄ノズル９の噴霧口は、吊手５のポケット状部位６に正しく向き合う。このようにすると、噴射洗浄ノズル９の洗浄液噴霧範囲１２が吊手５のポケット状部位６の中心に指向するため、ポケット状部位６に対する洗浄液噴霧時間をより多くできるので、有利である。   If the shape of the movable pipe 10 is, for example, L-shaped when viewed from the side of the apparatus, that is, the longitudinal direction of the beam 13, and the cleaning nozzle 9 is moved backward in the direction opposite to the conveying direction 2, the beam 13 is moved to the movable pipe. Before hitting 10, the spray nozzle of the cleaning nozzle 9 faces the pocket-shaped part 6 of the lifting hand 5 correctly. This is advantageous because the cleaning liquid spraying range 12 of the spray cleaning nozzle 9 is directed to the center of the pocket-shaped part 6 of the hand 5 so that the cleaning liquid spraying time for the pocket-shaped part 6 can be increased.

また、本実施例では、可動配管１０が可動部材としての機能も兼ねているが、可動配管１０に代えて剛体のアームを用い、主配管７と洗浄ノズル９との接続はフレキシブルホース等を用いてもよい。   In this embodiment, the movable pipe 10 also functions as a movable member. However, instead of the movable pipe 10, a rigid arm is used, and the main pipe 7 and the cleaning nozzle 9 are connected using a flexible hose or the like. May be.

FIG. 5 shows a schematic diagram of an embodiment of the movable cleaning nozzle facility. FIG. 5A is a plan view of the movable cleaning nozzle equipment and the plurality of metal plates 1 that are aligned and charged in the cleaning process, and FIG. 5B is a direction in which the movable cleaning nozzle equipment is conveyed in the metal plate 1. 5 is a side view as seen from the side, and FIG. 5 (c) is a front view of the movable cleaning nozzle facility as seen from the conveying direction 2 of the metal plate 1.

今回製作した可動式洗浄ノズル設備を用いて、５０枚の電気銅板を洗浄し、吊手５のポケット状部位６内部の洗浄状態を目視で観察した結果、５０枚中４６枚に電解液を成分とする結晶は観察されなかった。残る４枚については僅かに電解液の結晶の付着が観察された。   Using the movable cleaning nozzle equipment manufactured this time, 50 electrolytic copper plates were cleaned, and the cleaning state inside the pocket-shaped part 6 of the hand 5 was visually observed. No crystals were observed. On the remaining four sheets, slight adhesion of electrolyte crystals was observed.

比較のため、図１に示すような従来の洗浄装置において、金属板１枚の洗浄処理をするに当たり、１つの吊手５に対して吊手上部から左右交互に合計６回にわたり洗浄液が噴霧されるようにして、本発明の実施例と同様に５０枚の電気銅板を洗浄し、吊手５のポケット状部位６内部の洗浄状態を目視で観察した。その結果、５０枚中５枚に電解液を成分とする結晶は観察されなかった。残る４５枚については当該部位内部に電解液の結晶の付着が観察された。   For comparison, in the conventional cleaning apparatus as shown in FIG. 1, the cleaning liquid is sprayed six times in total from the upper part of the suspender to the left and right of the suspender 5 in the cleaning process of one metal plate. As described above, 50 electrolytic copper plates were cleaned in the same manner as in the example of the present invention, and the cleaning state inside the pocket-shaped portion 6 of the suspension 5 was visually observed. As a result, crystals containing the electrolyte as a component were not observed on 5 out of 50 sheets. With respect to the remaining 45 sheets, adhesion of electrolyte solution crystals was observed inside the portion.
