Description

本発明は陽極酸化皮膜の染色方法に関する。詳しくは染色により二色以上で模様表現する陽極酸化皮膜であって、その染色境界の色度合いを連続階調にグラデーション表現することで陽極酸化皮膜の色表現の幅を広げられるようにした加飾方法に関するものである。 The present invention relates to a method for dyeing an anodized film. Specifically, it is an anodized film that expresses a pattern with two or more colors by dyeing, and the decoration of the color expression of the anodized film can be expanded by gradation expressing the color degree of the dyeing boundary in a continuous tone. It is about the method.

従来、アルミニウムなどの金属表面を二色以上で色・模様の表現し、その色の境界を連続階調にグラデーション表現する加飾方法は数多くある。例えばベース色の上にスプレー塗装あるいは印刷で色を重ねて、グラデーションを表現する加飾方法は広く知られていた。 Traditionally, metal surfaces such as aluminum and the representation of the color and pattern in two or more colors, decorating method for gradation representation of the borders of the color contone are numerous. For example, a decoration method for expressing gradation by overlaying colors on a base color by spray painting or printing has been widely known.

アルミニウムなどにスプレー塗装をすることにより色の度合いを連続階調に表現する手法は、細部にわたる塗料の拡散が可能な専用のスプレー塗装具が知られている。また印刷によってグラデーションを表現する方法は、印刷原版を介しインキを印刷するものである。これらスプレー塗装あるいは印刷による加飾方法は、双方ともベース色の上に塗料若しくはインキを重ね硬化させるため塗装面若しくは印刷面に凹凸を生じる。そのためグラデーションの部分では表面が荒れ、光沢が不均一となるばかりでなく表面にざらつきがあり手触りも良くなかった。また、小さなハンドバックなどに入れて持ち歩く機会の多い化粧品容器は、手やハンドバック中の他の物との摩擦などで塗料若しくはインキが磨耗し、長期に安定した審美性を維持することは困難であった。 As a technique for expressing the degree of color in a continuous tone by spray coating on aluminum or the like, a dedicated spray coating tool capable of diffusing paint throughout the details is known. A method of expressing gradation by printing is to print ink through a printing original plate. In both of these decoration methods by spray coating or printing, paint or ink is overlaid and cured on the base color, resulting in unevenness on the painted or printed surface . Therefore, the surface of the gradation was rough, the gloss was not uniform, and the surface was rough and the touch was not good. In addition, cosmetic containers that are often carried around in small handbags, etc., have worn paint or ink due to friction with hands or other objects in the handbag, making it difficult to maintain stable aesthetics over the long term. It was.

そこで、本発明に係るグラデーション表現方法に関する特許文献1に陽極酸化皮膜処理したワーク表面に二色以上の顔料を染色し文字・図形を表現する手段が開示されている。また特許文献2に染色された陽極酸化皮膜を形成する染色部の一部を、脱色剤溶液に浸漬することによって脱色し、脱色部と染色部の境界をグラデーション表現する方法が開示されている。 Therefore, Patent Document 1 relating to the gradation expression method according to the present invention discloses a means for expressing characters and figures by dyeing two or more pigments on the surface of the workpiece that has been anodized. Further, Patent Document 2 discloses a method in which a part of a dyed portion that forms a dyed anodized film is decolored by immersing it in a decoloring agent solution, and the boundary between the decolored part and the dyed part is expressed in gradation .

特開平10−330994号公報JP-A-10-330994 特開2007−39757号公報JP 2007-39757 A

特許文献1では陽極酸化皮膜処理したアルミニウム表面に電気泳動法や電解染色処理により顔料を着色し、未封孔のワークにマスキング処理して脱色工程を組み合わせることで耐久性に富んだ模様を形成する。しかし化粧品容器などへの利用を考えてみた場合、電気泳動法や電解着色は容器の形状に起因する表面の電界にまだらが生じやすく、均一な着色は様々な困難を伴う。そのため高度に美観を要求する場合、工数がかさみ、価格押し上げの原因になる。 In Patent Document 1, a highly durable pattern is formed by coloring a pigment on an anodized aluminum surface by electrophoresis or electrolytic dyeing, and masking an unsealed workpiece and combining a decoloring process. . However, when considered for use in cosmetic containers and the like, electrophoretic methods and electrolytic coloring tend to cause mottle in the electric field on the surface due to the shape of the container, and uniform coloring involves various difficulties. For this reason, when a high degree of aesthetics is required, man-hours are increased , leading to price increases .

特許文献2は陽極酸化皮膜処理したアルミニウム表面を染色し、その染色部を脱色する脱色工程と組み合わせることで二色以上の模様を形成する。さらに脱色工程でワークを脱色剤溶液に一部を浸漬し、グラデーション部分の幅の振幅で脱色剤溶液の液面を相対的に上下動させる、あるいはワークを固定し脱色剤溶液の液面にグラデーション部分の幅の振幅の波を発生させることで境界部分のグラデーションを実現する。 Patent document 2 dyes | stains the aluminum surface which processed the anodic oxide film, and forms the pattern of two or more colors by combining with the decoloring process of decoloring the dyeing | staining part . Furthermore , part of the work is immersed in the decolorizer solution in the decolorization process, and the liquid surface of the decolorizer solution is moved up and down relatively with the amplitude of the width of the gradation part , or the work is fixed and the gradation on the liquid surface of the decolorizer solution The gradation of the boundary portion is realized by generating a wave having the amplitude of the width of the portion .

しかし、脱色工程で先の染料を脱色して境界部分にグラデーションを実現し、脱色部分に他の色を染色しようとする場合、先に濃色の染料でワーク全体を染色した後に境界部分にグラデーションを実現した脱色処理を行う。このように部分脱色されたワークは淡色の染料溶液に全体を浸漬されることにより脱色部分を第二の色に染色する。当然のことながら先に染色されていた濃色部分も淡色の染料で重ねて染色されることになるが、濃色により淡色は視覚上認識されないため、脱色部分のみが染色されたように見える。 However, if you want to decolorize the previous dye in the decolorization process to achieve gradation at the boundary , and dye other colors in the decolorized area , first color the entire work with dark dye and then gradation at the boundary. Decolorization processing that realizes. The part that has been partially decolored in this manner is immersed in the light dye solution to dye the decolored part to the second color. As a matter of course, the dark portion previously dyed is also superposed and dyed with a light dye, but since the light color is not visually recognized by the dark color, it appears that only the decolored portion is dyed.

また有底筒形のワークを特許文献2の処理を行い部分脱色し追染色しようとする場合、ワーク内に溜まった空気が排出され不用意な波が発生してしまう危険性があり、コントロールされたグラデーション部分を生成する阻害となる。そのため、溶液内に空気が溜まらないようワークの閉口側を下に向け脱色剤溶液に浸漬せざるを得ず、脱色部は有底筒状のワークの閉口側に位置するよう限定される。従って有底筒状のワークの染色は閉口側を淡色、開口側を濃色とデザイン上の制約が生じていた。 In addition, when the bottomed cylindrical workpiece is subjected to the process of Patent Document 2 to partially decolorize and perform additional dyeing , there is a risk that air accumulated in the workpiece is discharged and an inadvertent wave is generated, which is controlled. It becomes an obstacle to generate the gradation part. Therefore, the work must be immersed in the decoloring agent solution with the closed side of the work facing down so that air does not accumulate in the solution, and the decolorized part is limited to be located on the closed side of the bottomed cylindrical work. Therefore, in the dyeing of the bottomed cylindrical workpiece, the closed side is light color and the open side is dark color.

本発明は、このような問題点に鑑みてなされたもので、その目的とするところは陽極酸化皮膜処理にグラデーションといったバリエーションを、染色工程のみで得ようとするものである。さらに耐摩耗性があり色落ちのないグラデーション表現を低価格で実現する方法を提供するものである。また有底筒状のワークの多色染色で閉口側を濃色にすることができるようにするものである。   The present invention has been made in view of such problems, and an object of the present invention is to obtain a variation such as gradation in the anodized film treatment only by the dyeing process. Furthermore, the present invention provides a method for realizing a gradation expression that is wear-resistant and has no color fading at a low price. In addition, the closed side can be darkened by multicolor dyeing of a bottomed cylindrical workpiece.

また、ワークが一端を開口する有底筒状であり、染色工程が、ワークの全体又は一部を染色する第1の染色工程と、グラデーション表現をする第2の染色工程からなり、第2の染色工程を繰返して2色以上の染色を行うことも良いものである。この第2の染色工程は、第1の染色工程により染色されたワークの閉口側端部を前段階の染色より濃色の染色溶液に浸漬すると共に該浸漬の深さを周期的に変動させて染色の度合いを連続階調にしてグラデーション表現をするものである。尚、有底筒状のワークの閉口側は便宜上底となるが、口紅容器、マスカラ容器等のキャップのように必ずしも製品の下側になるものではない。 Further, the work has a bottomed cylindrical shape with one end opened, and the dyeing process includes a first dyeing process for dyeing all or a part of the work, and a second dyeing process for expressing gradation. It is also possible to repeat two or more colors by repeating the dyeing process. In the second dyeing process, the closed end of the work dyed in the first dyeing process is immersed in a darker dyeing solution than the dyeing in the previous stage and the depth of the immersion is periodically changed. Gradation is expressed by setting the degree of staining to continuous tone. The closed side of the bottomed cylindrical workpiece is the bottom for convenience, but is not necessarily the lower side of the product like a cap such as a lipstick container or a mascara container.

さらに染色溶液に粘度調整剤を混入することにより、ワーク表面における染色溶液の付着性を向上させることに加え、染色溶液の液面を安定させることも良いものである。
Furthermore, by mixing a viscosity modifier in the dyeing solution, in addition to improving the adhesion of the dyeing solution on the workpiece surface, it is also possible to stabilize the liquid surface of the dyeing solution.

また、ワークが一端を開口する有底筒状であり、染色工程が、ワークの全体又は一部を染色する第1の染色工程と、グラデーション表現をする第2の染色工程からなり、第2の染色工程を繰返して2色以上の染色を行うことも良いものである。この第2の染色工程は、第1の染色工程により染色されたワークの閉口側端部を前段階の染色より濃色の染色溶液に浸漬すると共に該浸漬の深さを周期的に変動させて染色の度合いを連続階調にしてグラデーション表現をするものである。尚、有底筒状のワークの閉口側は便宜上底となるが、口紅容器、マスカラ容器等のキャップのように必ずしも製品の下側になるものではない。 Further, the work has a bottomed cylindrical shape with one end opened, and the dyeing process includes a first dyeing process for dyeing all or a part of the work, and a second dyeing process for expressing gradation. It is also possible to repeat two or more colors by repeating the dyeing process. In the second dyeing process, the closed end of the work dyed in the first dyeing process is immersed in a darker dyeing solution than the dyeing in the previous stage and the depth of the immersion is periodically changed. Gradation is expressed by setting the degree of staining to continuous tone. The closed side of the bottomed cylindrical workpiece is the bottom for convenience, but is not necessarily the lower side of the product like a cap such as a lipstick container or a mascara container.

本発明陽極酸化皮膜の染色方法にあっては次に記載する効果を奏する。 The dyeing method for the anodized film of the present invention has the following effects.

陽極酸化皮膜処理されたアルミニウム材の表面は耐摩耗性がある。そのため細孔内に浸透され封孔された染料は指先や布などによる擦れなどでは色落ちしない。そのためアルミニウム表面に安定したグラデーション模様を形成できる。 Anodized film treated surface of the aluminum material is wear resistant. For this reason, the dye penetrated into the pores and sealed does not fade when rubbed with a fingertip or cloth. Therefore, a stable gradation pattern can be formed on the aluminum surface.

また有底筒状のワークにあって閉口側を濃色に染色できワーク表面の所定範囲を連続階調にグラデーション表現することで陽極酸化皮膜処理の色表現能力を拡大できる。 Further, in a bottomed cylindrical workpiece, the closed side can be dyed darkly, and the predetermined range of the workpiece surface can be expressed in gradations in a continuous tone, so that the color expression capability of the anodized film treatment can be expanded.

さらに本発明は、ワークを染色溶液に浸漬し液面と相対的に上下あるいは液面を波立たせるものである。これらに必要な装置は、多彩な模様を表現するため染色槽を設備している工場でワークをわずかの距離、連続して上下する簡素な装置を設ける、若しくは染色槽をわずかの距離、連続して上下する簡素な装置を設けること、あるいは染色溶液の液面を波立たせる設備や装置を追加するのみで実現できる。したがって、グラデーション表現に必要な設備を従来の染色槽に対する部分改造で済ませることができることから低いイニシャルコストで実現できるなどの効果がある。
In the present invention, the workpiece is immersed in a dyeing solution, and the surface is raised or lowered relative to the liquid surface. In order to express various patterns, the equipment required for these is to install a simple device that moves the workpiece up and down a short distance at a factory equipped with a dyeing tank, or the dyeing tank is a short distance continuously. This can be realized simply by providing a simple device that moves up and down , or by adding equipment and devices that make the liquid surface of the dyeing solution ripple . Therefore, since the equipment necessary for gradation expression can be completed by partial modification to the conventional dyeing tank, there is an effect that it can be realized at a low initial cost.

次に本発明を具体化した実施例について説明する。   Next, examples embodying the present invention will be described.

図1は本発明に係る染色作業の工程説明図である。プレス加工などで成形されたアルミニウムは表面研磨作業、脱脂作業、梨地加工、枠取付けなど所定の前処理工程1を終えて陽極酸化処理工程3に送られる。   FIG. 1 is a process explanatory diagram of a dyeing operation according to the present invention. The aluminum formed by pressing or the like is sent to the anodizing step 3 after finishing a predetermined pretreatment step 1 such as a surface polishing operation, a degreasing operation, a satin processing, and a frame attachment.

陽極酸化処理工程3はアルミニウム表面に陽極酸化皮膜を形成する工程である。ワーク100は電解質溶液として希硫酸等の入った浴に浸漬され、直流通電されて表面に陽極酸化皮膜を得る。 Anodizing step 3 is a step of forming an anodized film on the aluminum surface . Workpiece 100 is immersed in a bath tank containing the like dilute sulfuric acid as an electrolyte solution to obtain an anodized film on the DC application has been surface.

所定の陽極酸化皮膜を形成されたワーク100は水洗され染色工程5に送られる。染色工程5は陽極酸化皮膜に染料で所定の色に染色する工程である。   The workpiece 100 on which the predetermined anodized film is formed is washed with water and sent to the dyeing step 5. The dyeing step 5 is a step of dyeing the anodized film with a dye into a predetermined color.

染色工程5はワーク100を染色槽に浸漬する。染色工程5はワーク100全体を淡色の染色溶液に浸漬した後洗浄を行う第1の染色工程と、第1の染色工程に引き続き染色の度合いに差を生じるよう浸漬調整と洗浄を行う第2の染色工程が含まれる。第2の染色工程はワーク100に対し染色溶液30とワーク100表面との接触時間を連続的に変化させ、調整するもので染料溶液30に対する浸漬時間を変化させることにより、ワーク100の染色度合いを調整する。染色度合いを調整されたワーク100は連続階調にグラデーション部13を形成する。ここで第1の染色工程は金属地色で代用する場合には染色なしでも良い。
In the dyeing step 5, the workpiece 100 is immersed in a dyeing tank. The dyeing process 5 includes a first dyeing process in which the entire workpiece 100 is immersed in a light-colored dyeing solution and then cleaning, and a second dyeing adjustment and cleaning so as to cause a difference in the degree of dyeing following the first dyeing process. A dyeing step is included. In the second dyeing step , the contact time between the dye solution 30 and the surface of the work 100 is continuously changed and adjusted with respect to the work 100, and the dyeing degree of the work 100 is changed by changing the immersion time in the dye solution 30. adjust. The workpiece 100 having the dyeing degree adjusted forms a gradation portion 13 in continuous tone. Here, the first dyeing process may be performed without dyeing when the metal ground color is substituted.

第2の染色工程を終えたワーク100は、封孔前に再度第2の染色工程で用いた染料よりも濃色の染料を溶かす染色に浸漬することで三色のグラデーション部13を形成することができる。この前染色工程で用いた染料よりも濃色の染料で再度染色することを繰り返すことにより二色以上からなるグラデーション部13を形成することもできる。この時染料で着色されないアルミニウムの生地色も一つの色とみなすことができる。 The workpiece 100 that has finished the second dyeing process forms a three-color gradation portion 13 by immersing it in a dyeing tank that dissolves a darker dye than the dye used in the second dyeing process before sealing. be able to. The gradation part 13 composed of two or more colors can be formed by repeating the dyeing again with a dye that is darker than the dye used in the pre-dying step . At this time, the fabric color of aluminum which is not colored with a dye can also be regarded as one color.

染色を終えたワーク100は封孔処理工程7に送られ酢酸ニッケル等の封孔処理液に浸漬され封孔される。封孔処理によりワーク100に対する染色は定着される。さらにアルミニウム表面に形成された陽極酸化皮膜はアルミニウムの表面硬度を向上する。 The finished work 100 is sent to a sealing treatment step 7 and immersed in a sealing treatment solution such as nickel acetate to be sealed. The dyeing of the workpiece 100 is fixed by the sealing process. Furthermore, the anodized film formed on the aluminum surface improves the surface hardness of the aluminum.

以下、本発明に係るグラデーション方法につき説明を加える。   The gradation method according to the present invention will be described below.

図2は染色溶液30とワーク100とが相対的に上下動する場合の説明図である。相対的に上下動するとは、染色溶液30の液面31を固定してワーク100を上下する場合と、ワーク100を固定して染色溶液30の液面31を上下する場合の双方を含む。そこで図2に基づき、先に染色溶液30の液面31を固定してワーク100を上下する場合を説明する。   FIG. 2 is an explanatory diagram when the staining solution 30 and the workpiece 100 move up and down relatively. The relative vertical movement includes both the case where the liquid surface 31 of the dyeing solution 30 is fixed and the work 100 is moved up and down, and the case where the work 100 is fixed and the liquid surface 31 of the dyeing solution 30 is moved up and down. Therefore, a case where the work surface 100 is moved up and down with the liquid surface 31 of the staining solution 30 fixed first will be described with reference to FIG.

図2はワーク100を乱れのない液面31に対し上下させる第1のグラデーション方法説明図である。第1の染色工程を終えたワーク100は、第2の染色工程にて染色溶液30の液面31がグラデーション部13の下端位置(グラデーションの始まり)に合うように浸漬される。同浸漬の位置合わせは本発明を説明の基準として示すものである。 FIG. 2 is an explanatory diagram of a first gradation method for moving the workpiece 100 up and down with respect to the liquid level 31 without disturbance. The workpiece 100 that has finished the first dyeing process is immersed in the second dyeing process so that the liquid surface 31 of the dyeing solution 30 matches the lower end position (start of gradation) of the gradation portion 13. The alignment of the immersion indicates the present invention as a reference for explanation.

ここで完全染色部15とは、染色工程5でワーク100の一部を染色溶液30に浸漬して最も長時間染色され色濃く表現される部分である。グラデーション部13は、ワーク100の染色溶液30に浸漬される完全染色部15と染色溶液30に接触しない未染色部11との中間部で、染色溶液30に繰返し浸漬される部分である。ここで未染色部11とは第2の染色工程から考慮された名称で第1の染色工程ですでにワーク全体を淡色に染色されている部分も含まれるものである。   Here, the complete dyeing part 15 is a part that is partly dyed in the dyeing solution 30 in the dyeing step 5 and dyed for the longest time and is expressed in dark color. The gradation part 13 is an intermediate part between the completely dyed part 15 immersed in the dyeing solution 30 of the workpiece 100 and the undyed part 11 not in contact with the dyeing solution 30, and is a part repeatedly immersed in the dyeing solution 30. Here, the undyed portion 11 is a name taken into consideration from the second dyeing step, and includes a portion in which the entire work has already been dyed lightly in the first dyeing step.

そこでグラデーション部13の下端に液面31を合わせ浸漬されたワーク100は、染色溶液30の液面31をグラデーション部13の範囲で矢印S1方向に緩やかに繰返し上下される。緩やかな上下とは、液面31を波立たせないようにする上下動作であり、グラデーション部13の上端と下端との間で染色溶液30とワーク100表面との接触時間を連続的に変化させる。染色溶液30とワーク100表面との接触時間の差は、ワーク100の表面での染色の度合いに差を生じさせ連続階調のグラデーションを実現できる。 Therefore the workpiece 100 immersed combined liquid surface 31 to the lower end of the gradient portion 13 is gently repeatedly up and down the liquid level 31 of the staining solution 30 in the direction of the arrow S1 in the range of gradation portion 13. The gentle up / down operation is an up / down operation that prevents the liquid surface 31 from undulating, and continuously changes the contact time between the staining solution 30 and the surface of the workpiece 100 between the upper end and the lower end of the gradation portion 13. The difference in the contact time between the dyeing solution 30 and the surface of the workpiece 100 causes a difference in the degree of dyeing on the surface of the workpiece 100, thereby realizing a continuous gradation .

上記説明では染色溶液30とワーク100表面との接触時間を連続的に変化させることで説明を加えているが、染色溶液30に波が生じないようにワーク100を上下動するならば厳密な連続的変化でなくても染色度合いをコントロール下におくことが可能である。 In the above description, the description is given by continuously changing the contact time between the staining solution 30 and the surface of the workpiece 100. However, if the workpiece 100 is moved up and down so that no wave is generated in the staining solution 30, it is strictly continuous. It is possible to keep the degree of staining under control even if it is not a change .

また上記説明ではワーク100を液面31に対し上下する場合について説明しているが、ワーク100を固定し染色溶液30の液面31を上下動することでも同様に連続階調のグラデーションを実現できる。 In the above description, the case where the workpiece 100 is moved up and down with respect to the liquid surface 31 has been described. However, a continuous gradation can be similarly realized by moving the liquid surface 31 of the staining solution 30 up and down with the workpiece 100 fixed. .

この場合グラデーション部13の下端に液面31を合わせ浸漬されたワーク100を固定した状態で、染色溶液30の液面31はグラデーション部13の範囲で矢印S2方向に緩やかに連続して上下される。
In this case, the liquid level 31 of the dyeing solution 30 is gently and continuously moved up and down in the direction of the arrow S2 in the range of the gradation part 13 with the work 100 immersed in the liquid level 31 fixed to the lower end of the gradation part 13. .

尚、ワーク100の上下動は、複数のワーク100を取り付けた枠治具を機械的に上下動させる手段を用いることが出来る。また液面31の上下は、染色溶液30の入った染色を機械的に上下動させる手段を用いたり、内の液面の高さを機械的に上下させる手段を用いたりすることが出来る。この場合、内の液面が波立ちのないようにすることが必要である。 The workpiece 100 can be moved up and down by mechanically moving up and down a frame jig to which a plurality of workpieces 100 are attached. The upper and lower liquid level 31, the entered staining bath of dyeing solution 30 mechanically or by means for vertically moving the height of the liquid level in the tank mechanically can or using a means for vertically . In this case, it is necessary to prevent the liquid level in the tank from undulating.

以上説明のとおり、本発明はワーク100を矢印S1方向に、あるいは染色溶液30を矢印S2方向に上下動することで染色溶液30とワーク100とが相対的に上下動する。そうしてグラデーション部13の上限下限の間で、染色溶液30の被着時間が連続的に変化することで連続階調にしてグラデーションを形成する。そこでワーク100からマスキングパターンのような特別な印刷手法やスプレー塗装をせずにグラデーション部13を形成することができる。 As described above, in the present invention, the staining solution 30 and the workpiece 100 relatively move up and down by moving the workpiece 100 up and down in the direction of arrow S1 or the staining solution 30 in the direction of arrow S2. Thus, the gradation is formed in a continuous tone by continuously changing the deposition time of the dye solution 30 between the upper and lower limits of the gradation portion 13. Therefore, the gradation portion 13 can be formed from the workpiece 100 without performing a special printing method such as a masking pattern or spray coating .

図3は、液面31を波立たせ染色溶液30にワーク100を浸漬する第2のグラデーション方法説明図である。   FIG. 3 is an explanatory diagram of a second gradation method in which the work surface 100 is immersed in the dyeing solution 30 with the liquid surface 31 being waved.

ワーク100は、はじめにグラデーション部13の上端部を波面33の波頭に合うよう浸漬される。同浸漬の位置合わせは本発明を説明の基準として示すものである。   The workpiece 100 is first immersed so that the upper end portion of the gradation portion 13 matches the wave front of the wavefront 33. The alignment of the immersion indicates the present invention as a reference for explanation.

ここで完全染色部15とは、図3において波立つ液面33の波底より下部であり、染色溶液30に浸漬されるワーク100の一部である。グラデーション部13は、染色溶液30の液面33が形成する波頭と波底との間で繰返し接触する部分である。   Here, the complete dyeing part 15 is a part of the workpiece 100 that is below the wave bottom of the undulating liquid surface 33 in FIG. The gradation portion 13 is a portion that repeatedly contacts between the wave front and wave bottom formed by the liquid surface 33 of the staining solution 30.

完全染色部15の上端位置を波頭に合わせ浸漬されたワーク100は、所定の波高(グラデーション部13の幅)を持つ染色溶液30によって、繰り返し濡らされ未染色部11の下端に連続するグラデーション部13が決められる。染色溶液30の波は定点での液面31が安定して上下する波であれば、安定したグラデーションを生成できる。 The workpiece 100 immersed by aligning the upper end position of the complete dyed portion 15 with the wave front is repeatedly wetted by the dyeing solution 30 having a predetermined wave height ( width of the gradation portion 13) , and continues to the lower end of the undyed portion 11. Is decided. If the wave of the dye solution 30 is a wave in which the liquid surface 31 at a fixed point moves up and down stably, a stable gradation can be generated.

そうして図2と同様にグラデーション部13の上端と下端との間で染色溶液30とワーク100表面との接触時間を連続的に変化させ連続階調にぼかすことができる。   As in FIG. 2, the contact time between the staining solution 30 and the surface of the workpiece 100 can be continuously changed between the upper end and the lower end of the gradation portion 13 to blur the gradation.

さらに、グラデーションを安定して生成させようとする場合、染色溶液30に増粘剤、ゲル化剤などの粘度調整剤を混入させ粘度を増加調整すると良い。粘度調整剤の染色溶液30への混入は染色溶液30の完全染色部15への付着力を高める。   Furthermore, when it is going to produce | generate a gradation stably, it is good to mix viscosity adjusters, such as a thickener and a gelling agent, into the dyeing solution 30, and to increase the viscosity. The mixing of the viscosity adjusting agent into the dyeing solution 30 increases the adhesion of the dyeing solution 30 to the complete dyeing portion 15.

また、液面31にワーク100との干渉などで生ずる不規則な小さな波を起き難くでき、さらにグラデーション部13での付着力を高め、濡れを安定させることが出来る。   Further, it is possible to make it difficult for irregular small waves to be generated on the liquid surface 31 due to interference with the workpiece 100, etc., and to further enhance the adhesion at the gradation portion 13 and stabilize the wetting.

こうした粘度の増加調整で染色溶液30の内部結合力が高まり滴状の染色溶液30の悲惨を防止でき、未染色部11に不要な染色溶液30が被着することを防止できる。他方図2に示されるような第1のグラデーション方法では、染色溶液30に波立ちがないことになっているが、実際にはワーク100と液面31とが相対的に上下することから多少の波は生ずる。こうしてできる波を粘度の増加調整によって増加した染色溶液30の内部結合力で不用意な波高を低く抑えることで安定したグラデーションの表現を可能にする。 By adjusting the increase in the viscosity, the internal binding force of the dye solution 30 can be increased, and the misery of the drop-like dye solution 30 can be prevented, and the unnecessary dye solution 30 can be prevented from adhering to the undyed portion 11. On the other hand, in the first gradation method as shown in FIG. 2, there is no wave in the dyeing solution 30, but in actuality, since the workpiece 100 and the liquid surface 31 move up and down relatively, some wave is generated. Will occur. Thus it possible to reduce the inadvertent crest inside binding force staining solution 30 which was increased by increasing the adjustment of the wave viscosity allow for stable gradation representation.

以上説明の通り、図2、図3ではワーク100を染色溶液30の液面上で上下すること、あるいは液面を波立たせることで染色溶液30のワーク100表面への接触時間が連続的に変化するようにコントロールできる。   As described above, in FIGS. 2 and 3, the contact time of the staining solution 30 to the surface of the workpiece 100 is continuously increased by moving the workpiece 100 up and down on the surface of the staining solution 30 or by making the liquid surface undulate. It can be controlled to change.

図4はグラデーション部13を容器軸線と平行に設けたグラデーション説明図である。FIG. 4 is an explanatory diagram of gradation in which the gradation portion 13 is provided in parallel with the container axis.

図2、図3、図4において説明の通り、本発明はワーク100にマスキングパターンのような印刷による染色部分の選択をせずにグラデーション部13、完全染色部15を染色しぼかすことができる。そしてグラデーションがなされたワーク100は図1の封孔処理工程7に送られる。   As described with reference to FIGS. 2, 3, and 4, the present invention can stain the gradation portion 13 and the complete staining portion 15 without selecting a staining portion by printing such as a masking pattern on the work 100. FIG. And the workpiece | work 100 in which gradation was made is sent to the sealing processing process 7 of FIG.

封孔処理工程7は染色されたワーク100の表面に形成されている陽極酸化皮膜の細孔を封孔する工程である。封孔処理されたワークは水洗され、乾燥することで陽極酸化皮膜にグラデーションの入った染色の作業工程を終了する。   The sealing treatment step 7 is a step of sealing pores of the anodized film formed on the surface of the dyed work 100. The work subjected to the sealing treatment is washed with water and dried to finish the dyeing work process in which gradation is included in the anodized film.

尚、ワーク100は染色工程5で複数回の染色工程で染色を繰り返すことで二色以上の染色が可能となる。またこの場合の染色は先の染色工程で決定した色に加色されることから後工程になるに従いより濃色の染料溶液で染色されることが好ましい。   The work 100 can be dyed in two or more colors by repeating the dyeing in the dyeing process 5 in a plurality of dyeing processes. Further, since the dyeing in this case is added to the color determined in the previous dyeing process, it is preferably dyed with a darker dye solution as it becomes a subsequent process.

以上説明のとおり、本発明陽極酸化皮膜処理による加飾方法にあっては、印刷によるマスキングなどをせずにグラデーションを加えた多色の染色ができ、また本発明を実行するための設備も簡素であるなど発明の効果の欄に記載する効果を奏する。   As described above, the decorating method by the anodic oxide film treatment of the present invention can perform multi-color dyeing with gradation without masking by printing and the equipment for carrying out the present invention is also simple. The effect described in the column of the effect of the invention is obtained.

また図面に基づき、特定の実施の形態を持って説明を加えてきたが、本発明は図面に限定するものではなく、既に知られている本発明の効果を奏するどのような構成も採用されることができることは言うまでもないことである。   Although the description has been given with specific embodiments based on the drawings, the present invention is not limited to the drawings, and any configuration that exhibits the effects of the present invention that is already known is employed. It goes without saying that we can do it.
