Description

本発明は、金属箔製造用不溶性電極に関するものである。   The present invention relates to an insoluble electrode for producing a metal foil.

銅箔や銀箔等の金属箔を製造する装置が種々提案されている（例えば、出願人の先願に係る特開２００１−４９４８２）。   Various apparatuses for manufacturing metal foils such as copper foil and silver foil have been proposed (for example, Japanese Patent Application Laid-Open No. 2001-49482 according to the earlier application of the applicant).

この金属箔製造用不溶性電極について図１に基づいて簡単に説明すると、上部開口箱形の収納容体21内に配設され金属イオンを含む電解液（例えば、硫酸銅溶液）が溜められる電解層１と、この電解層１に溜められた電解液に浸漬される円筒状のドラム２とから成り、電解層１の内部にはドラム２の円弧外周面に対応する半円弧形状の電極板３（アノードプレート）が、前記収納容体21内に配設された支持体15（アノードフレーム）によって支持された状態で設けられ、この電極板３の上部外面にはブスバー４と呼ばれる給電体が設けられている。前記電解層１の底部には、この電解層１内に電解液を供給する液供給口11が設けられ、前記ブスバー４には、この電解層１からオーバーフローした電解液が通過する凹溝状の液通過部８が設けられている。また、前記ドラム２は軸12を支点に回転する構成である（本実施例と同一構成部分には同一符号を付した。）。   The insoluble electrode for producing a metal foil will be briefly described with reference to FIG. 1. The electrolytic layer 1 is provided in a box-shaped storage container 21 having an open top and in which an electrolytic solution containing metal ions (for example, a copper sulfate solution) is stored. And a cylindrical drum 2 immersed in the electrolytic solution stored in the electrolytic layer 1. Inside the electrolytic layer 1, a semi-circular electrode plate 3 (anode) corresponding to the outer peripheral surface of the drum 2 is provided. A plate is provided in a state supported by a support 15 (anode frame) provided in the storage container 21. A power supply called a bus bar 4 is provided on an upper outer surface of the electrode plate 3. . A liquid supply port 11 for supplying an electrolytic solution into the electrolytic layer 1 is provided at the bottom of the electrolytic layer 1, and the bus bar 4 has a concave groove shape through which the electrolytic solution overflowing from the electrolytic layer 1 passes. A liquid passage section 8 is provided. Further, the drum 2 is configured to rotate around a shaft 12 (the same components as those in the present embodiment are denoted by the same reference numerals).

電流は、前記ブスバー４に付設した電極体９から、ブスバー４，電極板３及び電解液を経由してドラム２に供給され、このドラム２から軸12を経由して放出される。この電流の流れによってドラム２の外周面には金属箔が形成される。この金属箔は、ドラム２から順次剥離されていく。   An electric current is supplied from the electrode body 9 attached to the bus bar 4 to the drum 2 via the bus bar 4, the electrode plate 3 and the electrolytic solution, and is discharged from the drum 2 via the shaft 12. The metal foil is formed on the outer peripheral surface of the drum 2 by the flow of the current. This metal foil is sequentially peeled from the drum 2.

また、金属箔の形成に伴って電解液中の金属イオンが消費されていく為、前記液供給口11から電解層１内に電解液を供給していき、この供給によって溢れた電解液は前記液通過部８から排出している。   Further, since metal ions in the electrolytic solution are consumed along with the formation of the metal foil, the electrolytic solution is supplied into the electrolytic layer 1 from the liquid supply port 11, and the electrolytic solution overflowed by this supply is The liquid is discharged from the liquid passage section 8.

金属箔の良好で且つ効率的な形成、即ち、薄く且つ均一な厚さの金属箔を早く形成する為には、ドラム２の外周面に電流が均一に流れることが重要である。その為、ドラム２や電極板３には、電気抵抗の低い金属製のもの（例えば、銅製のもの）を採用したいが、電解液の腐食作用も考慮する必要があり、よって、実際にはチタンやステンレス等の腐食に強い素材製のものが採用されている。   In order to form a good and efficient metal foil, that is, to quickly form a thin and uniform-thick metal foil, it is important that the current uniformly flow through the outer peripheral surface of the drum 2. For this reason, it is desired that the drum 2 and the electrode plate 3 be made of metal having a low electric resistance (for example, copper). However, it is necessary to consider the corrosive action of the electrolytic solution. A material made of a material resistant to corrosion such as stainless steel or stainless steel is used.

ところで、従来、電極板３と支持体15とは溶接されて一体となっている。しかし、溶接による一体構造では下記の問題点がある。   By the way, conventionally, the electrode plate 3 and the support 15 are welded and integrated. However, the following problems arise in the integrated structure by welding.

(1) 前記腐食等によって電極板３が劣化した際、補修や交換が必要となるが、この際、電極板３と支持体15とが一体であると、支持体15が邪魔で補修作業が厄介となったり、電極板３を破棄する際に支持体15も破棄しなければならなくなるという問題点がある。   (1) When the electrode plate 3 is deteriorated due to the corrosion or the like, repair or replacement is required. At this time, if the electrode plate 3 and the support 15 are integrated, the repair work is obstructed by the support 15. There is a problem that it becomes troublesome and that the support 15 must be discarded when the electrode plate 3 is discarded.

(2) 使用する電解液によって電極板３を切り替えたい場合、例えば、チタンに比して安価なステンレス製の電極板３を使用していた後に、ステンレスを腐食し易い電解液を使用するべくチタン製の電極板３に変更したい場合、電極板３と支持体15とが一体となったものを切り替えなければならず、切り替え作業が厄介であったり、電極板３と支持体15との一体物の為の広い保管場所の確保が必要となる。   (2) When it is desired to switch the electrode plate 3 depending on the electrolytic solution to be used, for example, after using the stainless steel electrode plate 3 which is inexpensive as compared with titanium, titanium is used to use an electrolytic solution which easily corrodes stainless steel. If it is desired to change to an electrode plate 3 made of aluminum, the electrode plate 3 and the support 15 must be switched, and the switching operation is troublesome, or the electrode plate 3 and the support 15 are integrated. It is necessary to secure a large storage space for

これらの問題点は、電極板３や支持体15が非常に大きい為（数メートル）、大きな問題点となっている。   These problems are serious because the electrode plate 3 and the support 15 are very large (several meters).

It becomes an electrode.

請求項２記載の発明においては、支持体の円弧支持部が電極板の形状に対応して外方から支持する構成であるから、この円弧支持部に支持された電極板はドラムの外周面に適正に対応する断面視円弧状となり、よって、この電極板からドラムに均一に電流が流れ、このドラムの外周面で均一な厚さの金属箔を良好に形成することができる実用性に秀れた金属箔製造用不溶性電極となる。   According to the second aspect of the present invention, since the arc support portion of the support is configured to support from the outside corresponding to the shape of the electrode plate, the electrode plate supported by the arc support portion is provided on the outer peripheral surface of the drum. It has an arc shape in cross-section corresponding to the proper shape, so that current flows uniformly from this electrode plate to the drum, and it is excellent in practicality that a metal foil with a uniform thickness can be favorably formed on the outer peripheral surface of this drum.

好適と考える本発明の実施の形態（発明をどのように実施するのが最良か）を、図面に基づいてその作用効果を示して簡単に説明する。   Preferred embodiments of the present invention (how best to carry out the invention) will be briefly described with reference to the drawings and the effects thereof.

電極板３と支持体15とを分離することで、電極板３のみの補修，交換，切り替えを容易に達成することができる。   By separating the electrode plate 3 from the support 15, repair, replacement and switching of only the electrode plate 3 can be easily achieved.

即ち、従来は電極板３と支持体15とが溶接により一体とされていた為、支持体15が邪魔で電極板３の補修作業が厄介であったり、交換，切り替えの際は支持体15と一緒に交換，切り替えを行わなければならないという問題点があったが、本発明によれば、支持体15から電極板３を分離することで、前記補修作業は容易に達成でき、また、交換，切り替えは電極板３のみとすることができる。   That is, since the electrode plate 3 and the support 15 are conventionally integrated by welding, the support 15 obstructs the work of repairing the electrode plate 3, and the replacement of the support 15 with the support 15 is difficult. According to the present invention, the repair work can be easily achieved by separating the electrode plate 3 from the support 15, although there has been a problem that replacement and switching must be performed together. Switching can be performed only by the electrode plate 3.

また、例えば、前記支持体15に、前記断面視円弧状の電極板３の形状に対応して外方から支持する円弧支持部28を設け、この支持体15の円弧支持部28に前記電極板３を支承状態に設け、この電極板３と前記支持体15の円弧支持部28とを着脱自在に固定すれば、円弧状の電極板３に変形が極めて生じにくい状態でこの電極板３を円弧支持部28に固定して電解層１を形成でき、これにより、電極板３をドラム２の外周面に適正に対応する断面視円弧状で保持することができ、よって、この電極板３からドラム２に均一に電流を流して前記ドラム２の外周面で均一な厚さの金属箔を形成できることになるなど、一層実用的となる。   Further, for example, the support 15 is provided with an arc support portion 28 that supports the electrode plate 3 from the outside corresponding to the shape of the electrode plate 3 having an arc shape in a sectional view, and the arc support portion 28 of the support 15 is provided with the electrode plate. If the electrode plate 3 is provided in a supporting state and the electrode plate 3 and the arc support portion 28 of the support 15 are detachably fixed, the electrode plate 3 can be arc-shaped in a state in which the arc-shaped electrode plate 3 is hardly deformed. The electrolytic layer 1 can be formed by being fixed to the support portion 28, whereby the electrode plate 3 can be held on the outer peripheral surface of the drum 2 in an arc shape in a sectional view appropriately corresponding to the electrode plate 3. 2 becomes even more practical, for example, a metal foil having a uniform thickness can be formed on the outer peripheral surface of the drum 2 by applying a current uniformly to the drum 2.

また、例えば、前記電極板３と前記支持体15とをボルト固定構造で着脱自在に固定すれば、単にボルトを締めたり緩めたりするだけで、電極板３と支持体15との固定及び分離を行って前記電極板３の修理，交換，切り替えを一層容易に達成できることとなるなど、一層実用的となる。   Further, for example, if the electrode plate 3 and the support 15 are detachably fixed by a bolt fixing structure, the fixing and separation of the electrode plate 3 and the support 15 can be performed simply by tightening or loosening the bolts. By doing so, the repair, replacement, and switching of the electrode plate 3 can be more easily achieved, which makes the electrode plate 3 more practical.

また、ボルトの締め付け度合いを調整することで支持体15に対する電極板３の配設位置を調整して電極板３の歪みの修正を行うことができ、これにより、電極板３とドラム２とを適正な位置関係として、このドラム２の外周面で均一な厚さの金属箔を形成できることとなるなど、一層実用的となる。   In addition, by adjusting the degree of tightening of the bolts, the disposition of the electrode plate 3 with respect to the support 15 can be adjusted to correct the distortion of the electrode plate 3, whereby the electrode plate 3 and the drum 2 can be fixed. As a proper positional relationship, a metal foil having a uniform thickness can be formed on the outer peripheral surface of the drum 2, which is more practical.

また、例えば、前記電極板３に電極支持部22を設け、この電極支持部22若しくはこの電極支持部22に設けた電極側突片部６と、前記支持体15若しくは前記支持体15に設けた支持体側突片部７とをボルト固定構造で固定することにより前記電極板３と支持体15とを着脱自在に固定すれば、電極板３を支持体15若しくは支持体側突片部７に直に固定するのではなく、電極支持部22若しくは電極支持部22及び電極側突片部６を介して固定するため、電流が流れる電極板３に例えば貫通孔やネジ孔を設ける必要がなく、よって、電極板に電流を均一に流すことが可能で、ドラムの外周面に均一な厚さの金属箔を形成できることとなるなど、一層実用的となる。   Further, for example, an electrode support portion 22 is provided on the electrode plate 3, and the electrode support portion 22 or the electrode-side projecting piece portion 6 provided on the electrode support portion 22 and the support 15 or the support 15 are provided. If the electrode plate 3 and the support 15 are detachably fixed by fixing the support-side protruding piece 7 with a bolt fixing structure, the electrode plate 3 is directly attached to the support 15 or the support-side protruding piece 7. Instead of being fixed, it is fixed via the electrode support portion 22 or the electrode support portion 22 and the electrode-side protruding piece portion 6, so that it is not necessary to provide, for example, a through-hole or a screw hole in the electrode plate 3 through which a current flows. The current can be uniformly applied to the electrode plate, and a metal foil having a uniform thickness can be formed on the outer peripheral surface of the drum, which is more practical.

また、例えば、前記電極支持部22又は前記電極側突片部６に貫通孔25若しくはネジ孔26を設け、前記支持体15又は前記支持体側突片部７にネジ孔26若しくは貫通孔25を設け、この貫通孔25に貫通若しくはこのネジ孔26にボルト27を螺着して前記電極板３の電極支持部22と前記支持体15とをボルト止め固定すれば、単にボルト27を貫通孔25に貫通若しくはネジ孔26に螺着するだけで、電極板３と支持体15とを作業性良く固定できることとなるなど、一層実用的となる。   Further, for example, a through hole 25 or a screw hole 26 is provided in the electrode support portion 22 or the electrode side projecting piece 6, and a screw hole 26 or a through hole 25 is provided in the support 15 or the support side projecting piece 7. If the bolt 27 is screwed into the through hole 25 or screwed into the screw hole 26 and the electrode support portion 22 of the electrode plate 3 and the support 15 are bolted and fixed, the bolt 27 is simply inserted into the through hole 25. The electrode plate 3 and the support 15 can be fixed with good workability only by being screwed into the through hole or the screw hole 26, so that it becomes more practical.

また、例えば、前記電極支持部22に電極側突片部６を前記電極板３の端部から外方に突出状態に設け、この電極側突片部６に貫通孔25若しくはネジ孔26を設け、前記支持体15の円弧支持部28にネジ孔26を設けて、この貫通孔25にボルト27を貫通若しくはネジ孔26にボルト27を螺着して前記電極側突片部６と前記円弧支持部28とを固定すれば、電極板３に対して外方に突出する電極側突片部６においてボルト27を着脱する構成であるから、このボルト27の着脱が電極板３によって邪魔されたりせず、よって、電極板３と支持体15との着脱を良好に達成できることとなるなど、一層実用的となる。   Further, for example, the electrode-side protruding portion 6 is provided on the electrode support portion 22 so as to protrude outward from the end of the electrode plate 3, and the electrode-side protruding portion 6 is provided with a through hole 25 or a screw hole 26. A screw hole 26 is provided in an arc support portion 28 of the support body 15, and a bolt 27 is passed through the through hole 25 or a bolt 27 is screwed into the screw hole 26 so that the electrode-side projecting piece 6 and the arc support If the portion 28 is fixed, the bolt 27 is attached and detached at the electrode-side projecting piece 6 projecting outward with respect to the electrode plate 3. Therefore, the attachment / detachment between the electrode plate 3 and the support 15 can be satisfactorily achieved, which is more practical.

また、例えば、前記支持体15に前記支持体側突片部７を内方に突出状態に設けて前記円弧支持部28を形成し、前記支持体側突片部７に貫通孔25若しくはネジ孔26を設け、前記電極支持部22にネジ孔26を設け、この貫通孔25に貫通若しくはネジ孔26にボルト27を螺着して前記電極支持部22と前記円弧支持部28とを固定すれば、支持体15に対して内方に突出する支持体側突片部７で電極支持部22を支承した状態で固定でき、これにより、電極板３の端部と支持体15の側面とが略面一状態となるように前記電極板３と支持体15とを固定することが可能で、よって、例えば電極板３及び支持体15を所定の容体に整然とした状態で収容できることとなるなど、一層実用的となる。   Also, for example, the support-side protruding piece 7 is provided in the support 15 in a protruding state inward to form the arc-shaped support section 28, and the support-side protruding piece 7 has a through hole 25 or a screw hole 26. The electrode support portion 22 is provided with a screw hole 26, and the electrode support portion 22 and the arc support portion 28 are fixed by penetrating the through hole 25 or screwing a bolt 27 into the screw hole 26. The electrode support portion 22 can be fixed in a state where the electrode support portion 22 is supported by the support-side protruding piece 7 projecting inward with respect to the body 15, so that the end of the electrode plate 3 and the side surface of the support 15 are substantially flush with each other. The electrode plate 3 and the support 15 can be fixed so that the electrode plate 3 and the support 15 can be housed in a predetermined container in an orderly manner. Become.

本発明の具体的な本実施例について図面に基づいて説明する。   A specific embodiment of the present invention will be described with reference to the drawings.

本実施例は、上部が開口した箱形収納容体21の内部に電極板３を支持するための支持体15を設け、この支持体15に電極板３を支承状態で設けて収納容体21内に電解層１を形成し、この電解層１に金属イオンを含む電解液を溜め、この電解液にドラム２を浸漬し、前記電極板３から前記電解液を経由して前記ドラム２に電流を流すことにより、このドラム２の外周面で金属箔を製造する装置である。   In the present embodiment, a support 15 for supporting the electrode plate 3 is provided inside a box-shaped storage container 21 having an open top, and the electrode plate 3 is provided on the support 15 in a supported state. An electrolytic layer 1 is formed, an electrolytic solution containing metal ions is stored in the electrolytic layer 1, a drum 2 is immersed in the electrolytic solution, and a current flows from the electrode plate 3 to the drum 2 via the electrolytic solution. This is an apparatus for producing a metal foil on the outer peripheral surface of the drum 2.

ドラム２は円筒状のものを採用している。このドラム２の中心部には軸12が設けられ、この軸12を支点にドラム２は回転する。   The drum 2 has a cylindrical shape. A shaft 12 is provided at the center of the drum 2, and the drum 2 rotates around the shaft 12 as a fulcrum.

このドラム２は、例えば、鉄製のインナードラムの外周面にチタン製のトップスキン（アウタードラム）を被嵌したものを採用する。   As the drum 2, for example, a drum in which a top skin (outer drum) made of titanium is fitted on the outer peripheral surface of an inner drum made of iron is used.

軸12は、陰極（カソード）に接続している。   The shaft 12 is connected to a cathode (cathode).

電解層１の内面、即ち、電極板３（アノードプレートと呼ばれている。）は、ドラム２の下半分の外周面形状に対応する上方が開口した断面視円弧形状である。尚、図１の紙面表裏方向は、ドラム２の垂直外縁に対応する垂直形状で、この部位には電極板３は設けられていない。   The inner surface of the electrolytic layer 1, that is, the electrode plate 3 (referred to as an anode plate) has an arcuate cross-sectional view with an open top corresponding to the outer peripheral surface shape of the lower half of the drum 2. 1 has a vertical shape corresponding to the vertical outer edge of the drum 2, and the electrode plate 3 is not provided at this position.

また電極板３は、約１／４円弧状の二枚の円弧状の電極板３・３を対向状態に設け、この電極板３間の電解層１の中央底部には、電解層１内に前記電解液を供給する為の液供給口11を設けている。   The electrode plate 3 is provided with two approximately 1/4 arc-shaped electrode plates 3.3 opposed to each other, and a central bottom portion of the electrolytic layer 1 between the electrode plates 3 is provided inside the electrolytic layer 1. A liquid supply port 11 for supplying the electrolytic solution is provided.

この二枚の円弧電極板３・３は、別体の支持体15に夫々固定することによって所定位置に支持せしめている。   The two arc electrode plates 3 are supported at predetermined positions by being fixed to separate supports 15, respectively.

また、電極板３と支持体15とは、着脱自在に固定している。以下、この固定構造について詳述する。   Further, the electrode plate 3 and the support 15 are detachably fixed. Hereinafter, this fixing structure will be described in detail.

夫々の支持体15には、前記断面視円弧状の電極板３、即ち、前記二枚の円弧電極板３・３の形状に対応して外方から支持する円弧支持部28を設けている。   Each of the supports 15 is provided with an electrode plate 3 having an arc shape in a sectional view, that is, an arc support portion 28 which is supported from outside corresponding to the shape of the two arc electrode plates 3.

前記電極板３は、前記円弧支持部28に着脱自在に固定している。   The electrode plate 3 is detachably fixed to the arc support portion 28.

この着脱自在な固定構造としては、ボルト固定構造を採用している。   As this detachable fixing structure, a bolt fixing structure is adopted.

具体的には、電極板３は、図３，図４に示すように、下側から電極支持部22で支持した構成のものを採用し、この電極支持部22には電極側突片部６を設け、この電極板側突片部６を前記円弧支持部28にボルト固定構造で固定する構成を採用している。即ち、電極側突片部６と円弧支持部28とのいずれか一方に貫通孔25を設け、他方にネジ孔26を設け、貫通孔25側からネジ孔26側に向けてボルト27を螺合し、電極側突片部６と円弧支持部28、即ち、電極板３と支持体15とを固定している。尚、ボルト27を取り外せば、電極板３と支持体15とを分離することができる。   Specifically, as shown in FIGS. 3 and 4, the electrode plate 3 has a configuration supported by the electrode support 22 from below, and the electrode support 22 has an electrode-side projecting piece 6. The electrode plate side protruding piece 6 is fixed to the arc support 28 by a bolt fixing structure. That is, a through hole 25 is provided in one of the electrode-side protruding piece 6 and the arc support portion 28, a screw hole 26 is provided in the other, and a bolt 27 is screwed from the through hole 25 to the screw hole 26. Then, the electrode-side protruding piece 6 and the arc-shaped support 28, that is, the electrode plate 3 and the support 15 are fixed. If the bolt 27 is removed, the electrode plate 3 and the support 15 can be separated.

即ち、電極板３を電極支持部22で支持した構成とし、電極支持部22若しくはこの電極支持部22に設けた電極側突片部６に貫通孔25若しくはネジ孔26を設けたのは、電極板３の電流が流れる部位、即ち、電極板３に貫通孔25やネジ孔26を設けると、流れる電流が不均一となってしまうからである。この点、本実施例は、電極板３に貫通孔25やネジ孔26を設けず、電極支持部22若しくは電極側突片部６に貫通孔25やネジ孔26を設ける構成としたから、電極板３の電流が流れる部位に電流が均一に流れることになり、よって、前記ドラム２の外周面で均一な厚さの金属箔を形成できることになる。   That is, the configuration in which the electrode plate 3 is supported by the electrode support portion 22 and the through hole 25 or the screw hole 26 is provided in the electrode support portion 22 or the electrode-side protruding piece portion 6 provided in the electrode support portion 22 is the same as that of the electrode. This is because, if a through-hole 25 or a screw hole 26 is provided in the portion of the plate 3 through which the current flows, that is, in the electrode plate 3, the flowing current becomes non-uniform. In this regard, in this embodiment, the through hole 25 and the screw hole 26 are not provided in the electrode plate 3, and the through hole 25 and the screw hole 26 are provided in the electrode support portion 22 or the electrode-side projecting piece 6. The current flows uniformly in the portion of the plate 3 where the current flows, so that a metal foil having a uniform thickness can be formed on the outer peripheral surface of the drum 2.

電極板３は、腐食に強く且つ通電性の良い素材製の板材、例えば、チタン製，ステンレス製等の板材を採用する。また、電極板３は、円弧状に湾曲できる厚さのもの、例えば、チタン製のものを採用した場合、厚さ１０〜４０ｍｍ程度のものを採用する。   The electrode plate 3 is made of a plate made of a material that is resistant to corrosion and has good electrical conductivity, for example, a plate made of titanium, stainless steel, or the like. The electrode plate 3 has a thickness that can be curved in an arc shape, for example, when it is made of titanium, a thickness of about 10 to 40 mm is used.

電極支持部22は、腐食に強い素材製のもの（通電性は必要無い）、例えば、チタンやステンレス等の金属製，ＦＲＰやＰＶＣ等の合成樹脂製のものを採用する。   The electrode support 22 is made of a material that is resistant to corrosion (electricity is not required), such as a metal such as titanium or stainless steel, or a synthetic resin such as FRP or PVC.

尚、電極側突片部６も、電極支持部22と同様、例えば、チタンやステンレス等の金属製，ＦＲＰやＰＶＣ等の合成樹脂製のものを採用すると良い。   The electrode-side protruding piece 6 may be made of, for example, a metal such as titanium or stainless steel, or a synthetic resin such as FRP or PVC, similarly to the electrode support 22.

即ち、電極板３と電極支持部22とは、電極板３から電極支持部22に電流が逃げない状態（絶縁状態）で固定する。電極支持部22として絶縁性の高いものを採用した場合は、単なる固定構造を採用しても良いが、電極支持部22として絶縁性の低いものを採用した場合は、電極板３と電極支持部22との間に絶縁ゴム等の絶縁層を介在させると良い。   That is, the electrode plate 3 and the electrode support portion 22 are fixed in a state where current does not escape from the electrode plate 3 to the electrode support portion 22 (insulating state). When a high insulating material is used as the electrode support portion 22, a simple fixing structure may be used. However, when a low insulating material is used as the electrode support portion 22, the electrode plate 3 and the electrode support portion may be used. Preferably, an insulating layer such as insulating rubber is interposed between the insulating layer 22 and the insulating layer 22.

また、本実施例では、電極支持部22として、前記電極板３の外面に積層する支持板部16を採用している。   Further, in the present embodiment, the support plate portion 16 laminated on the outer surface of the electrode plate 3 is adopted as the electrode support portion 22.

そして、この支持板部16の外面に上下方向に所定間隔を置いて電極側突片部６を複数並設している。   A plurality of electrode-side projecting pieces 6 are arranged on the outer surface of the support plate 16 at predetermined intervals in the vertical direction.

支持板部16が前記電極板３を円弧形状に保持し、この支持板部16を前記複数の電極側突片部６が保持する。尚、電極板３は、前記厚さの設定の為、支持板部16によって積層状態で支持しないと湾曲や歪みが非常に発生し易い。   A support plate 16 holds the electrode plate 3 in an arc shape, and the support plate 16 is held by the plurality of electrode side projecting pieces 6. In addition, since the electrode plate 3 is set in the above-described thickness, the electrode plate 3 is very likely to be bent or distorted unless it is supported by the support plate 16 in a stacked state.

電極側突片部６は、支持板部16及び電極板３の端部（左右側部）から外方に突出状態に設けた構成とし、この電極側突片部６の突出部位が前記支持体15の円弧支持部28に当接するように構成している。   The electrode-side protrusion 6 is provided so as to protrude outward from the ends (left and right sides) of the support plate 16 and the electrode plate 3, and the projecting portion of the electrode-side protrusion 6 is the support member. It is configured to abut on the fifteen arc support portions 28.

そして、この電極側突片部６の突出部位に貫通孔25を設け、前記円弧支持部28にして前記貫通孔25と対応する位置にネジ孔26を設け、ネジ軸29の一端部に頭部30が設けられた構成のボルト27を貫通孔25側からネジ孔26に挿入してこのネジ軸29をネジ孔26に螺着し、頭部30を貫通孔25の周縁に係止して前記電極側突片部６の突出部位、即ち、前記電極板３の下側の電極支持部22を支持体15に固定している。   Then, a through hole 25 is provided at a protruding portion of the electrode-side protruding piece portion 6, a screw hole 26 is provided at a position corresponding to the through hole 25 as the arc support portion 28, and a head is provided at one end of the screw shaft 29. A bolt 27 having a structure provided with 30 is inserted into the screw hole 26 from the through hole 25 side, the screw shaft 29 is screwed into the screw hole 26, and the head 30 is locked to the peripheral edge of the through hole 25, The projecting portion of the electrode-side protruding piece 6, that is, the electrode support portion 22 on the lower side of the electrode plate 3 is fixed to the support 15.

従って、このボルト27の着脱により、電極板３を支持体15に固定したり、電極板３を支持体15から取り外したりすることができる。   Therefore, by attaching and detaching the bolt 27, the electrode plate 3 can be fixed to the support 15 or the electrode plate 3 can be removed from the support 15.

図中符号10は、前記ボルト27のネジ軸29をネジ孔26に螺着した際、このボルト27の頭部30が突出することを防止する為の径大孔部である。   Reference numeral 10 in the figure denotes a large-diameter hole for preventing the head 30 of the bolt 27 from projecting when the screw shaft 29 of the bolt 27 is screwed into the screw hole 26.

貫通孔25は、前記ネジ軸29より径大のものを採用すると良い。この貫通孔25とネジ軸29との径の差により、電極板３を歪ませずに支持体15と固定せしめ易くなる。   Preferably, the through hole 25 has a diameter larger than that of the screw shaft 29. Due to the difference in diameter between the through hole 25 and the screw shaft 29, the electrode plate 3 can be easily fixed to the support 15 without being distorted.

前記電極側突片部６は、前述のように、前記電極板３の左右側部に多数突出状態で設けられている。この多数の電極側突片部６の突出部位を用いて多数のボルト27により前記電極板３を前記支持体15に固定する。   As described above, the electrode-side protruding pieces 6 are provided on the left and right sides of the electrode plate 3 so as to protrude in a large number. The electrode plate 3 is fixed to the support 15 with a large number of bolts 27 using the projecting portions of the large number of electrode side projecting pieces 6.

支持体15に固定した電極板３に歪みがあった場合、前記多数のボルト27の締め付け度合いを夫々調整することで歪みを消失せしめる。この歪みの消失により、電極板３の円弧内面とドラム２の円弧外面とが適正な位置関係となり（双方がドラム２の回転軸を中心とする円弧形状となり）、このドラム２の外面で均一な厚さの金属箔を形成することができる。   If the electrode plate 3 fixed to the support 15 is distorted, the distortion is eliminated by adjusting the degree of tightening of the plurality of bolts 27, respectively. Due to the disappearance of the distortion, the inner surface of the circular arc of the electrode plate 3 and the outer surface of the circular arc of the drum 2 have an appropriate positional relationship (both have a circular arc shape centered on the rotation axis of the drum 2), and are uniform on the outer surface of the drum 2. A metal foil having a thickness can be formed.

この歪みの消失は、前記電極板３が湾曲できる厚さであるから、良好に達成することができる。また、電極板３の湾曲状態を保持する電極支持部22は支持板部16で構成され、支持板部16も湾曲できないような厚さではなく、湾曲可能であるから、この点からも、前記歪みの消失は良好に達成することができる。   This disappearance of the distortion can be satisfactorily achieved because the electrode plate 3 has a thickness that can be bent. In addition, the electrode support portion 22 for holding the curved state of the electrode plate 3 is constituted by the support plate portion 16, and the support plate portion 16 is not so thick that it cannot be bent, but can be bent. Dissipation can be successfully achieved.

また、電極板３の左右側部から突出する電極側突片部６においてボルト27の締め付け度合いを調整できる構成であるから、電極板３や支持板部16に邪魔されずに前記調整を良好に行うことができる。   Further, since the degree of tightening of the bolt 27 can be adjusted at the electrode-side protruding pieces 6 protruding from the left and right sides of the electrode plate 3, the adjustment can be performed well without being hindered by the electrode plate 3 and the support plate 16. It can be carried out.

尚、ボルト27として頭部の無いネジ部だけのボルトを採用し、このボルトを前記ネジ孔26に螺着し、更に、このボルトにナットを螺着することで電極板３を支持体10に固定する構成を採用しても良い。   In addition, a bolt having only a screw portion without a head is adopted as the bolt 27, and this bolt is screwed into the screw hole 26, and further, a nut is screwed into the bolt to attach the electrode plate 3 to the support body 10. A configuration for fixing may be adopted.

電極板３の上部外面には、図１に示すように、ブスバー４と呼ばれる電極体を当接している。   As shown in FIG. 1, an electrode body called a bus bar 4 is in contact with the upper outer surface of the electrode plate 3.

このブスバー４には、前記電解層１からオーバーフローした前記電解液を通過せしめる為の上部が開口した凹溝状の液通過部８を設けている。この液通過部８の存在により、ブスバー４は上部が開口した断面視コ字形となっている。   The bus bar 4 is provided with a concave groove-shaped liquid passage portion 8 having an open top for allowing the electrolytic solution overflowing from the electrolytic layer 1 to pass therethrough. Due to the presence of the liquid passage portion 8, the bus bar 4 has a U-shape in cross section with an open top.

ブスバー４は、チタン板製のもの、若しくは、通電性の高い金属板（例えば銅板）にチタン板をライニングしたり、チタンをメッキしたりしたものを採用している。尚、ブスバー４がチタン板製の場合、このチタン板として厚さ１０〜８０ｍｍ程度のものを採用する。   The bus bar 4 is made of a titanium plate, or a metal plate (for example, a copper plate) having high electrical conductivity, which is lined with a titanium plate or plated with titanium. When the bus bar 4 is made of a titanium plate, a titanium plate having a thickness of about 10 to 80 mm is used.

また、ブスバー４は、電極体９（陽極）に付設している。この電極体９から供給される電流は、ブスバー４、電極板３、電解液の順に通過した後、ドラム２の外周面に達し、このドラム２から前記軸12を通過して放出される。この電流の通過により、ドラム２の外周面に金属箔（銅箔や銀箔等、電解液によって決定する）を形成できる。   The bus bar 4 is attached to the electrode body 9 (anode). The current supplied from the electrode body 9 passes through the bus bar 4, the electrode plate 3, and the electrolytic solution in this order, reaches the outer peripheral surface of the drum 2, and is discharged from the drum 2 through the shaft 12. Through the passage of the current, a metal foil (copper foil, silver foil, or the like determined by the electrolytic solution) can be formed on the outer peripheral surface of the drum 2.

電極体９は、電解液の腐食作用を受けない為、通電性の良い素材製のもの、例えば、銅製や銀製のものを採用する。   The electrode body 9 is made of a material having good electrical conductivity, for example, copper or silver, because it is not affected by the corrosive action of the electrolytic solution.

この電極体９には、整流器（図示省略）を通過した定電圧の定電流が作用する。   A constant current of a constant voltage that has passed through a rectifier (not shown) acts on the electrode body 9.

本実施例は上述のように構成したから、ボルト27を取り付けたり取り外したりすることで電極板３と支持体15とを固定したり分離したりすることができ、よって、電解層１に溜めた電解液の影響等によって電極板３を交換しなければならなくなった際、電極板３のみの交換が可能で、交換コストの低下を達成することができる。   Since the present embodiment is configured as described above, the electrode plate 3 and the support 15 can be fixed or separated by attaching and detaching the bolts 27, and thus, the electrode plate 3 and the support 15 can be stored in the electrolytic layer 1. When the electrode plate 3 has to be replaced due to the influence of the electrolytic solution or the like, only the electrode plate 3 can be replaced, and a reduction in replacement cost can be achieved.

また、使用する電解液によって電極板３を適宜選択して採用する場合、例えば、普段は腐食にはやや弱いが安価なステンレス製の電極板３を採用し、強力な腐食作用を有する電解液を使用する為に腐食に非常に強いが高価なチタン製の電極板３に切り替える場合、電極板３のみの交換で済むことになり、交換作業は容易で、且つ、使用しない電極板３の保管場所も広いスペースを必要としないことになる。   In addition, when the electrode plate 3 is appropriately selected and adopted depending on the electrolytic solution to be used, for example, an inexpensive stainless steel electrode plate 3 which is usually slightly weak to corrosion is employed, and an electrolytic solution having a strong corrosive action is used. When switching to an electrode plate 3 made of titanium which is very resistant to corrosion but expensive for use, only the electrode plate 3 needs to be replaced, and the replacement work is easy and the storage place of the unused electrode plate 3 Would also not require a lot of space.

また、電極板３を補修する場合、電極板３を支持体15から分離し、電極板３のみの状態として補修作業を行うことができ、よって、支持体15が補修作業の邪魔になったりせず、補修作業を的確且つ容易に行うことができる。   Further, when the electrode plate 3 is repaired, the electrode plate 3 can be separated from the support 15 and the repair work can be performed with only the electrode plate 3 in a state, so that the support 15 can hinder the repair work. And the repair work can be performed accurately and easily.

また、電極板３を支持体15に溶接する構成であると、電極板３が非常に大きなものである為、溶接の際に歪みが発生し、電極板３に研磨処理等の仕上げ加工を施してドラム２の形状に対応するようにしなければならなかったが、本実施例によれば、溶接を行わない構成の為、当然ながら歪みの発生は無く、更に、夫々のボルト27の締め付け度合いを調整することで、電極板３を適正な円弧形状とすることができ、よって、ドラム２の外周面で良好に金属箔を形成できることになる。   If the electrode plate 3 is welded to the support 15, the electrode plate 3 is very large, so distortion occurs at the time of welding, and the electrode plate 3 is subjected to finishing such as polishing. However, according to this embodiment, since the welding is not performed, there is naturally no distortion, and the degree of tightening of each bolt 27 is reduced. By making the adjustment, the electrode plate 3 can be formed into an appropriate arc shape, so that the metal foil can be favorably formed on the outer peripheral surface of the drum 2.

また、電極板３の内の電流が流れる部位、即ち、電極板３の厚さを湾曲できる厚さに設定したから、前記ボルト27の締め付け度合いの調整による作用（電極板３を適正な円弧形状とする作用）は極めて良好に発揮されることになる。   In addition, since the portion of the electrode plate 3 through which the current flows, that is, the thickness of the electrode plate 3 is set to a thickness that can be bent, the operation by adjusting the degree of tightening of the bolt 27 (the electrode plate 3 has an appropriate arc shape) ) Is extremely well exhibited.

また、電極板３の内の電流が流れる部位、即ち、電極板３にボルト27を螺着する為のネジ孔26や貫通孔25を設けず、電流の流れない部位、即ち、支持板部16に前記ネジ孔26若しくは貫通孔25を設ける構成を採用したから、電極板３の全域に電流の流れを阻害する孔等が存在しないことになり、それだけ電流が均一に流れることができてドラム２の外周面で良好に金属箔を形成できることになる。   Further, a portion of the electrode plate 3 through which a current flows, that is, a portion through which no current flows without providing a screw hole 26 or a through hole 25 for screwing a bolt 27 into the electrode plate 3, that is, a support plate portion 16 Since the screw hole 26 or the through hole 25 is provided in the electrode plate 3, there is no hole or the like that obstructs the flow of current in the entire area of the electrode plate 3. The metal foil can be formed satisfactorily on the outer peripheral surface of.

また、電極板３の側部に電極側突片部６を設け、この電極側突片部６を支持体15に固定する構成を採用したから、電極板３の電流が流れる部位に全く影響を与えずに電極板３側から支持体15側にボルト27を貫通させることができ、よって、ボルト27の取り付け構造として簡易なものを採用でき、且つ、ボルト27の取り付け作業を良好に行える構成とすることができる。   Further, since the electrode-side protruding portion 6 is provided on the side of the electrode plate 3 and the electrode-side protruding portion 6 is fixed to the support 15, the portion of the electrode plate 3 through which the current flows is completely affected. The bolt 27 can be penetrated from the side of the electrode plate 3 to the side of the support 15 without being provided, so that a simple structure for mounting the bolt 27 can be adopted and the mounting work of the bolt 27 can be performed well. can do.

図５〜図９は別例で、図５は、前記支持体15に、外方に向けて突出する支持体側突片部７を設けて円弧支持部28を形成し、この支持体側突片部７にネジ孔26を設け、前記電極側突片部６に貫通孔25を設け、貫通孔25側からネジ孔26にボルト27を挿入して螺着する構成のものである。   FIGS. 5 to 9 show another example, and FIG. 5 shows a case where the support 15 is provided with a support-side protruding piece 7 protruding outward to form an arc-shaped support section 28. 7, a screw hole 26 is provided, a through hole 25 is provided in the electrode side protruding piece 6, and a bolt 27 is inserted into the screw hole 26 from the through hole 25 side and screwed.

図５によれば、前記のように電極板３側からボルト27を挿入する構成も、また、電極側突片部６にネジ孔26を設け、支持体側突片部７に貫通孔25を設け、支持体15側からボルト27を挿入する構成も、どちらでも選択することができ、汎用性に秀れることになる。   According to FIG. 5, the bolt 27 is inserted from the electrode plate 3 side as described above. Also, the screw hole 26 is provided in the electrode-side protruding piece 6 and the through-hole 25 is provided in the support-side protruding piece 7. The configuration in which the bolt 27 is inserted from the side of the support 15 can be selected, which is excellent in versatility.

図６，図７は、支持体15に内方に向けて突出する支持体側突片部７を設け、この支持体側突片部７には貫通孔25を設け、一方、電極板３の外面に積層する電極支持部22、即ち、支持板部16の左右側部にはネジ孔26を前記支持体側突片部７の貫通孔25と対応するように設け、貫通孔25側からネジ孔26にボルト27を挿入して螺着することで、前記支持体側突片部７で支持板部16を支承した状態で、この支持板部16と支持体15とを固定する構成としたものである。   6 and 7 show that the support 15 has a support-side protruding piece 7 protruding inward. The support-side protruding piece 7 is provided with a through hole 25, while the outer surface of the electrode plate 3 is provided on the outer surface of the electrode plate 3. Screw holes 26 are provided on the left and right sides of the electrode support portion 22 to be laminated, that is, on the left and right sides of the support plate portion 16 so as to correspond to the through holes 25 of the support-side protruding piece portion 7. The support plate 16 and the support 15 are fixed in a state where the support plate 16 is supported by the support-side projecting piece 7 by inserting and bolting the bolt 27.

また、図６，図７における支持体側突片部７は、支持体15に溶接により一体に設けられている。   6 and 7, the support-side protruding piece 7 is integrally provided on the support 15 by welding.

図６，図７によれば、電極板３及び支持板部16の左右側面と支持体15の左右側面とが面一の状態で固定することが可能で、これにより、収納容体21に電極板３及び支持体15を整然とした状態で配設することができる。   According to FIGS. 6 and 7, the left and right side surfaces of the electrode plate 3 and the support plate portion 16 and the left and right side surfaces of the support body 15 can be fixed to be flush with each other. 3 and the support 15 can be arranged in an orderly manner.

図８，図９は、支持体15に固定位置決め調整可能に支持体側突片部７を複数設けて円弧支持部28を形成し、前記支持体側突片部７と支持板部16とをボルト27で連結することで電極板３と支持体15とを固定するものである。   FIGS. 8 and 9 show a case in which a plurality of support-side projecting pieces 7 are provided on the support 15 so as to be fixed and adjustable so as to form an arc-shaped support section 28, and the support-side projecting piece 7 and the support plate 16 are bolted to each other. Thus, the electrode plate 3 and the support 15 are fixed by the connection.

具体的には、支持体側突片部７を断面視Ｌ字状の板材７Ａで構成し、この板材７Ａの一端側を支持体15の内側面に当接してボルト46・ナット47により固定することで、他端側を前記支持体15の内方に突出させて円弧支持部28を形成している。   More specifically, the support-side protruding piece 7 is formed of a plate 7A having an L-shaped cross section, and one end of the plate 7A is brought into contact with the inner surface of the support 15 and fixed with bolts 46 and nuts 47. Thus, the other end side protrudes inward of the support body 15 to form the arc support portion 28.

更に具体的には、図９に示すように、板材７Ａの一端部に貫通孔35を設け、支持体15の円弧傾斜部位近傍に貫通孔45を設け、これら貫通孔35・45にボルト46を挿通してナット47止めすることで、支持体15に板材７Ａを固定位置決め調整可能に設けている。   More specifically, as shown in FIG. 9, a through hole 35 is provided at one end of the plate member 7A, a through hole 45 is provided in the vicinity of a circularly inclined portion of the support 15, and bolts 46 are provided in the through holes 35. By inserting and fixing the nut 47, the plate 7A is provided on the support 15 so as to be fixedly positionable and adjustable.

即ち、ボルト46・ナット47による固定位置決め調整により、支持体15に対する板材７Ａの取り付け固定位置（固定角度）を所望する位置（角度）に設定できる構成となっている。   That is, the fixing position (fixed angle) of attaching the plate 7A to the support 15 can be set to a desired position (angle) by the fixed positioning adjustment by the bolt 46 and the nut 47.

図８，図９によれば、電極板３の湾曲度合いに応じて板材７Ａの支持体15に対する取り付け固定角度を調整できるため、円弧状の電極板３に合わせて取り付け固定位置を調整してドラム２の外周面に対応する適性な円弧支持部28を形成でき、これにより、電極板３に歪みが極めて生じにくい状態で前記電極板３を支持体15に固定できる。   According to FIGS. 8 and 9, since the fixing angle of attachment of the plate 7A to the support 15 can be adjusted according to the degree of curvature of the electrode plate 3, the attachment and fixing position is adjusted in accordance with the arc-shaped electrode plate 3 and the drum is fixed. An appropriate arc-shaped support portion 28 corresponding to the outer peripheral surface of the electrode plate 3 can be formed, whereby the electrode plate 3 can be fixed to the support 15 in a state where the electrode plate 3 is hardly distorted.

よって、電極板３からドラム２に、より一層均一に電流を流すことが可能となり、このドラム２の外周面で均一の厚さの精度の高い金属箔を製造することが可能となる。   Therefore, it is possible to more uniformly supply a current from the electrode plate 3 to the drum 2, and it is possible to manufacture a highly accurate metal foil having a uniform thickness on the outer peripheral surface of the drum 2.
