Description

本発明は、バレル装置ならびにバレルめっき方法に関するものである。   The present invention relates to a barrel apparatus and a barrel plating method.

従来より、例えばセラミック電子部品における外部電極のめっき形成など、小型電子部品にめっき加工を施す装置として、バレルめっき装置がある（特許文献１参照）。バレルめっき装置は回転可能に支持されたバレル容器を備えており、バレル容器の内部には、陰極端子が延出している。めっきを行うに際しては、バレル容器の内部に多数の被めっき物であるワーク及びダミー片を入れ、バレル容器をその上部が一部液面から露出する程度、めっき液に浸漬させる。そして、バレル容器を回転させると共に、陰極端子を介して被めっき物に通電してその表面にめっきを行う。   2. Description of the Related Art Conventionally, there is a barrel plating apparatus as an apparatus for performing plating on small electronic components such as plating formation of external electrodes in ceramic electronic components (see Patent Document 1). The barrel plating apparatus includes a barrel container that is rotatably supported, and a cathode terminal extends inside the barrel container. When plating is performed, a large number of workpieces and dummy pieces, which are objects to be plated, are placed inside the barrel container, and the barrel container is immersed in the plating solution so that the upper portion thereof is partially exposed from the liquid surface. And while rotating a barrel container, it supplies with electricity to a to-be-plated object via a cathode terminal, and the surface is plated.

ところで、このようなバレルめっきにおいては、ワークが収容されたバレル容器を一部液面から露出するようにめっき液槽に沈めた際に、ワークの一部がめっき液内に沈まずに、液面に浮いていることがある。このようなことが生じると、浮き上がっていたワークにはめっきが十分に施されず、めっき厚のばらつき等、めっき品質の低下が問題となる。   By the way, in such barrel plating, when a barrel container containing a workpiece is submerged in a plating bath so as to be partially exposed from the liquid surface, a part of the workpiece is not submerged in the plating solution. It may float on the surface. When this occurs, the workpiece that has been lifted up is not sufficiently plated, and there is a problem of deterioration in plating quality such as variations in plating thickness.

これに関連しては、特許文献１において、バレル容器内にワークと共に多数のフロートを収容し、浮かび上がってきたワークがフロートにぶつかることで、ワークを浮上させた気体をワークから分離させ、ワークを再び沈むように企図したものが開示されている。   In this connection, in Patent Document 1, a large number of floats are accommodated together with the workpiece in the barrel container, and the floating workpiece collides with the float, so that the gas floating the workpiece is separated from the workpiece, Is intended to sink again.

かかる特許文献１に開示のものは、いったん、バレル容器をめっき液槽内の予め決められた位置に沈めた時点で、フロートの下方に適切に沈んでいたワークには上記の効果を奏する可能性がある。しかしながら、バレル容器をめっき液に沈めていく過程で、フロートの上方に浮いてしまったワークや、フロートの下方にあってもフロートにくっついているワークに対しては、その後、沈むことは期待できない。さらに、フロートの投入や、めっき後のフロートとワークとの分離などが必要となり、作業や管理が煩雑になる問題がある。特に、かかる問題は、異なるめっき液を用い、異なるバレル容器に入れ替えるなどして複数回めっきして、めっき層を複層形成する場合などには大きな問題となる。
特開平７−１１８８９５号公報 The one disclosed in Patent Document 1 has a possibility that the above-described effect can be exerted on a work that has been appropriately submerged below the float once the barrel container is submerged in a predetermined position in the plating bath. There is. However, in the process of submerging the barrel container in the plating solution, it is not expected that the workpiece that floats above the float or that adheres to the float even below the float will sink afterwards. . Furthermore, there is a problem that work and management are complicated because it is necessary to throw in the float or to separate the float and the workpiece after plating. In particular, such a problem becomes a serious problem when a plurality of plating layers are formed by using different plating solutions and being replaced with different barrel containers to form multiple plating layers.
JP-A-7-118895

本発明は、このような問題に鑑みてなされたものであり、作業の煩雑化を伴うことなくワークの浮上状態を解消することができる、バレル装置等を提供することを目的とする。   The present invention has been made in view of such a problem, and an object of the present invention is to provide a barrel device or the like that can eliminate the floating state of a workpiece without complicating work.

上述した課題を解決するため、本発明のバレル装置は、処理液が充填される処理液槽と、前記処理液槽内に回転可能に配置されるバレル容器と、前記バレル容器内の浮上ワークに対して上方から気体を噴射する気体噴射手段とを備える。   In order to solve the above-described problems, the barrel apparatus of the present invention is provided with a treatment liquid tank filled with a treatment liquid, a barrel container rotatably disposed in the treatment liquid tank, and a floating work in the barrel container. On the other hand, gas injection means for injecting gas from above is provided.

前記気体噴射手段は、所定の軌道に沿って移動可能に設けられたノズルを含むように構成してもよい。   The gas injection means may include a nozzle that is movably provided along a predetermined trajectory.

好適には、前記バレル容器は、多孔部分を有しており、前記気体噴射手段は、前記バレル容器の外側から気体を噴射する。   Suitably, the said barrel container has a porous part, and the said gas injection means injects gas from the outer side of the said barrel container.

同課題を解決するため、本発明は、バレルめっき方法をも提供する。このバレルめっき方法は、内部に少なくともワークが収容されているバレル容器を用意し、前記バレル容器を、めっき液が充填されるめっき液槽に、該バレル容器の一部がめっき液から露出するようにして沈め、前記バレル容器内で浮上しているワークに該バレル容器外の上方から空気を噴射し、その後で、バレル容器を回転させながらワークに対するめっきを行う。   In order to solve this problem, the present invention also provides a barrel plating method. In this barrel plating method, a barrel container in which at least a workpiece is accommodated is prepared, and the barrel container is exposed to a plating solution tank filled with a plating solution so that a part of the barrel container is exposed from the plating solution. Then, air is sprayed from above the barrel container to the workpiece that has been submerged and floated in the barrel container, and thereafter, the workpiece is plated while rotating the barrel container.

上述した本発明によれば、フロートなどワークと混合されるものを用いなくて済み、作業の煩雑化を伴うことなくワークの浮上状態を解消することができる。   According to the present invention described above, it is not necessary to use a material that is mixed with a workpiece such as a float, and the floating state of the workpiece can be eliminated without complicating the work.

また、本発明のバレル装置において、気体噴射手段を所定の軌道に沿って移動可能に設けられたノズルを含むように構成した場合、液面のどこに浮上してくるか想定しづらい浮上ワークに対して、満遍なく気体噴射し、より確実に気体を吹き付けることができる。   Further, in the barrel apparatus of the present invention, when the gas injection means is configured to include a nozzle that is movably provided along a predetermined trajectory, it is difficult to assume where the liquid surface will float on the floating work Thus, gas can be injected evenly and gas can be sprayed more reliably.

さらに、本発明のバレル装置において、バレル容器が多孔部分を有しており、気体噴射手段がバレル容器の外側から気体を噴射する場合には、既存のバレル容器の多孔部分を利用してバレル容器の外から浮上ワークの沈降を促進することができ、機構の複雑化を伴わず、既存のバレル装置にも容易に適用することができる。   Furthermore, in the barrel apparatus of the present invention, when the barrel container has a porous portion and the gas injection means injects gas from the outside of the barrel container, the barrel container is made using the porous portion of the existing barrel container. It is possible to promote the sedimentation of the floating work from outside, and it can be easily applied to an existing barrel apparatus without complicating the mechanism.

なお、本発明の他の特徴及びそれによる作用効果は、添付図面を参照し、実施の形態によって更に詳しく説明する。   The other features of the present invention and the operational effects thereof will be described in more detail with reference to the accompanying drawings.

以下、本発明の実施の形態を添付図面に基づいて説明する。なお、図中、同一符号は同一又は対応部分を示すものとする。   Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding parts.

図１は、本実施の形態に係るバレルめっき装置の構成を示す図である。バレルめっき装置１は、めっき液槽３と、バレル容器５と、陰極端子７及び陽極端子９と、気体噴射手段１１とを備えている。   FIG. 1 is a diagram showing a configuration of a barrel plating apparatus according to the present embodiment. The barrel plating apparatus 1 includes a plating solution tank 3, a barrel container 5, a cathode terminal 7 and an anode terminal 9, and gas injection means 11.

めっき液槽３は、上方が開口した槽であり、内部にめっき液１３が充填されている。バレル容器５は、内部が中空の多角柱状の容器であり、めっきを行う際にめっき液槽３内に回転可能に配置される。より詳細には、バレル容器５は、ほぼ水平方向に延長する回転軸Ｒが貫通する一対の側壁と、それら側壁を架橋するパネルとを有している。また、通常、側壁は、正多角形をなしており、パネルは、その正多角形の各辺から延びているため、正多角形の辺数と同数の面を有している。さらに、パネルには、ワークの通過は規制しつつめっき液１３の流通は確保される程度の大きさの孔からなる多孔部分が設けられている。   The plating solution tank 3 is a tank whose upper side is open, and is filled with a plating solution 13. The barrel container 5 is a hollow polygonal column-shaped container, and is disposed rotatably in the plating solution tank 3 when performing plating. More specifically, the barrel container 5 has a pair of side walls through which a rotation axis R extending in a substantially horizontal direction passes, and a panel that bridges the side walls. Moreover, since the side wall is usually a regular polygon and the panel extends from each side of the regular polygon, the side wall has the same number of sides as the regular polygon. Further, the panel is provided with a porous portion composed of holes of such a size that the passage of the plating solution 13 is ensured while the passage of the workpiece is restricted.

また、バレル容器５には、図示省略する回転駆動手段とバレル容器支持手段とが接続されている。かかる回転駆動手段及びバレル容器支持手段は共に周知の態様でよく、その詳細な説明は省略するが、簡単に述べると次のような機能を有するものである。回転駆動手段は、バレル容器５を回転させるための手段である。バレル容器支持手段は、バレル容器５を支持する手段であって、バレル容器５は、めっき液１３に浸漬されたりめっき液１３から引き上げられたりする際、また、めっき液槽３の上方に移動させられたり、逆にめっき液槽３の上方から他の位置に移動させられたりする際、このバレル容器支持手段を介して昇降や移動される。   Further, the barrel container 5 is connected with a rotation drive means and a barrel container support means (not shown). Both the rotation driving means and the barrel container supporting means may be in a well-known manner and will not be described in detail. However, in brief, they have the following functions. The rotation driving means is means for rotating the barrel container 5. The barrel container support means is a means for supporting the barrel container 5. When the barrel container 5 is immersed in the plating solution 13 or pulled up from the plating solution 13, the barrel container 5 is moved above the plating solution tank 3. When it is moved to the other position from the upper side of the plating solution tank 3, it is moved up and down via the barrel container support means.

陰極端子７は、バレル容器５内に配置された棒状の部材であって、したがって、めっき時にはめっき液槽３内に配置される。陰極端子７の先端部近傍は、露出されていると共に、他の部分は、連続的に電気的絶縁被覆されている。陰極端子７は、電源１５の陰極側に接続されており、電源１５の陽極側には、陽極端子９が接続される。陽極端子９は、めっき液槽３内であって、バレル容器３の外側に配置される。   The cathode terminal 7 is a rod-shaped member disposed in the barrel container 5 and is therefore disposed in the plating solution tank 3 during plating. The vicinity of the tip of the cathode terminal 7 is exposed, and the other parts are continuously electrically insulated. The cathode terminal 7 is connected to the cathode side of the power source 15, and the anode terminal 9 is connected to the anode side of the power source 15. The anode terminal 9 is disposed inside the plating solution tank 3 and outside the barrel container 3.

気体噴射手段１１は、バレル容器５内に収容されているワーク１７のうち、めっき液１３の液面に浮き上がっている浮上ワーク１７ａに対して、上方から、例えば空気などの気体を噴射するものである。気体噴射手段１１は、所定の軌道に沿って移動可能に設けられたノズル１９を有する。ノズル１９は、本実施の形態では、バレル容器５の回転軸Ｒの延長方向に沿って、往復移動する。ノズル１９は、鉛直下方に向けて気体を噴射するようにしてもよいし、やや斜め下方に向けて気体を噴射するようにしてもよい。また、気体噴射手段１１は、バレル容器５の外側に配置されており、例えば、前述したバレル容器支持手段の一部に取り付けることができる。   The gas injection means 11 is for injecting a gas such as air from above to the floating work 17 a floating on the liquid surface of the plating solution 13 among the works 17 accommodated in the barrel container 5. is there. The gas injection means 11 has a nozzle 19 provided so as to be movable along a predetermined trajectory. In the present embodiment, the nozzle 19 reciprocates along the extending direction of the rotation axis R of the barrel container 5. The nozzle 19 may inject the gas vertically downward, or may inject the gas slightly obliquely downward. Moreover, the gas injection means 11 is arrange | positioned on the outer side of the barrel container 5, for example, can be attached to a part of barrel container support means mentioned above.

次に、以上のように構成されたバレルめっき装置の作用、すなわち、本実施の形態に係るバレルめっき方法について説明する。まず、ワーク１７やダミーボールを収容したバレル容器５を用意する。そして、かかるバレル容器５を、めっき液１３が充填されためっき液槽３内に沈める。より詳細には、バレル容器５は、その上部がめっき液槽３内のめっき液１３から露出するようにして沈められる。次に、気体噴射手段１１を作動させて、バレル容器５内で浮上している浮上ワーク１７ａに対して、バレル容器５外の上方から空気を噴射する。すなわち、図２に示されるように、気体噴射手段１１のノズル１９を、空気噴射させながら往復移動させる。それによって、浮上ワーク１７ａをバレル容器５の底部へと沈める。その後、めっき液１３中でバレル容器５を回転させると共に、陰極端子７及び陽極端子９を介してワーク１７に通電し、ワーク１７表面にめっきを行う。このようにして、気体噴射した後にめっきを行うため、浮上ワークに起因しためっき厚のばらつき等、めっき品質の低下を抑制することができる。   Next, the effect | action of the barrel plating apparatus comprised as mentioned above, ie, the barrel plating method which concerns on this Embodiment is demonstrated. First, the barrel container 5 containing the workpiece 17 and dummy balls is prepared. Then, the barrel container 5 is submerged in the plating solution tank 3 filled with the plating solution 13. More specifically, the barrel container 5 is submerged so that the upper part thereof is exposed from the plating solution 13 in the plating solution tank 3. Next, the gas injection means 11 is operated to inject air from the upper side outside the barrel container 5 to the floating work 17 a floating in the barrel container 5. That is, as shown in FIG. 2, the nozzle 19 of the gas injection means 11 is reciprocated while air is injected. Thereby, the floating work 17a is sunk to the bottom of the barrel container 5. Thereafter, the barrel container 5 is rotated in the plating solution 13, and the work 17 is energized through the cathode terminal 7 and the anode terminal 9 to perform plating on the surface of the work 17. In this way, since the plating is performed after the gas is jetted, it is possible to suppress a decrease in plating quality such as a variation in plating thickness caused by the floating workpiece.

さらに、図３及び図４に基づいて、浮上ワークの沈降について説明する。浮上ワーク１７ａは、まず、ワーク１７を収容したバレル容器５をめっき液槽３に沈める過程で、バレル容器５が沈められても、その内部で沈みきらずにめっき液１３の液面上に残ってしまうことで生じうる。図３に示されるように、発生した浮上ワーク１７ａは、バレル容器５内のめっき液１３の液面上に、一部を露出する態様で浮遊している。これに対して、ノズル１９から空気を噴射する。   Furthermore, sedimentation of the floating work will be described based on FIGS. 3 and 4. First, the floating workpiece 17a remains on the surface of the plating solution 13 without sinking inside the barrel vessel 5 even when the barrel vessel 5 is submerged in the process of sinking the barrel vessel 5 containing the workpiece 17 into the plating solution tank 3. It can be caused by. As shown in FIG. 3, the generated floating workpiece 17 a floats on the liquid surface of the plating solution 13 in the barrel container 5 in a manner that a part thereof is exposed. On the other hand, air is injected from the nozzle 19.

空気が吹き付けられた浮上ワーク１７ａは、図４に示されるように、その空気圧で押し上げられ、全体がめっき液１３に浸かる。このようにしてひとたび、全周が濡れた浮上ワーク１７ａは、表面張力が得られなくなり、自重によりめっき液１３中を沈降し、他の大多数のワーク１７のなかに混ざっていく。   As shown in FIG. 4, the floating work 17 a to which the air has been blown is pushed up by its air pressure, and the whole is immersed in the plating solution 13. In this way, once the floating work 17a whose entire circumference is wet cannot obtain surface tension, it settles in the plating solution 13 due to its own weight, and is mixed with the majority of other works 17.

以上のように、本実施の形態では空気の吹き付けで浮上ワークの沈降を達成するため、前述した特許文献１のようにフロートの投入や、めっき後のフロートとワークとの分離など、作業や管理が煩雑になる問題を伴わない。特に、異なるめっき液を用い複数回めっきして、めっき層を複層形成する場合には、本実施の形態は有益である。また、フロートを用いた態様では、いったんは沈められフロートの下方に位置したワークがその後浮上した際に再度沈める場合を想定しており、バレル容器を最初にめっき液中に沈める際に当初からフロートに混じって沈まなかったワークに対しては何ら効果が期待できなかった。その一方、本実施の形態では、当初から沈まなかったワークに対しても有効に機能し、めっき前に浮上ワークの沈降を促進することができる。さらに、気体噴射手段が所定の軌道に沿って移動可能に設けられたノズルを含むので、液面のどこに浮上してくるか想定しづらい浮上ワークに対して、満遍なく気体噴射し、より確実に気体を吹き付けることができる。   As described above, in this embodiment, in order to achieve the settling of the floating work by blowing air, work and management such as the introduction of the float and separation of the float and the work after plating are performed as in Patent Document 1 described above. Is not complicated. In particular, this embodiment is useful when a plurality of plating layers are formed using different plating solutions to form multiple plating layers. Moreover, in the aspect using the float, it is assumed that the workpiece once submerged and positioned below the float is submerged again when it floats, and when the barrel container is submerged in the plating solution for the first time, it is floated from the beginning. No effect could be expected for workpieces that did not sink due to mixing. On the other hand, in this Embodiment, it functions effectively also with respect to the workpiece | work which did not sink from the beginning, and the sedimentation of a floating workpiece | work can be accelerated | stimulated before plating. Furthermore, since the gas injection means includes a nozzle that is movably provided along a predetermined trajectory, it is possible to inject the gas evenly to the floating work, where it is difficult to assume where the liquid will float, and to ensure more reliable gas Can be sprayed.

また、本実施の形態のように気体噴射であれば、液体噴射に対して次のような利点が存在する。まず、めっき液には発泡性があるところ、これに液体を噴射すると、めっき液を泡立てることとなり浮上ワークを沈降させることができたとしても、泡立ちによるめっき品質の低下が懸念される。さらに、回転駆動されるバレル容器内において流体噴射させる場合には、既存のバレルめっき装置に適用できず、且つ、新作する場合も機構の複雑化が避けられない。その一方で、バレル容器外から噴射させる場合、液体噴射では浮上ワークに液体が適切に吹き付けられず浮上ワークの沈降が期待できない。これらの問題に対し、本実施の形態であれば気体噴射であるため、めっき液を徒に泡立てることもなく、且つ、既存のバレル容器の多孔部分を利用してバレル容器の外から浮上ワークの沈降を促進することができ、機構の複雑化を伴わず、既存のバレルめっき装置にも容易に適用することができる。さらに、バレル容器外の上方に気体噴射手段を設けることで、気体噴射手段はめっき液には浸からず、また、めっき液の跳ね返りはバレル容器を通過してまでは気体噴射手段に付着し難いため、異なるめっき液を用い複数回めっきして、めっき層を複層形成する場合でも、気体噴射手段にめっき液が付着し、それが次のめっき工程に持ち込まれる恐れもない。加えて、バレル容器外からの液体噴射であれば、噴射液体の一部がバレル容器に衝突して跳ね返り、気体噴射手段に付着する恐れもあるが、気体噴射であればそのような跳ね返りの問題もない。よって、それによっても、気体噴射手段に付着した液体が、次のめっき工程に持ち込まれる恐れもない。また、バレル容器外に気体噴射手段を設ける態様ならば、気体噴射手段をバレル容器支持手段の一部に固定することも選択でき、その場合、バレル容器支持手段の性質上、気体噴射手段を常にバレル容器に対して一定の位置・姿勢に配置させることができる。   In addition, the gas injection as in the present embodiment has the following advantages over the liquid injection. First, the plating solution has foaming properties. If a liquid is sprayed on the plating solution, the plating solution is bubbled, and even if the floating work can be allowed to settle, there is a concern that the plating quality may be lowered due to bubbling. Furthermore, when fluid is jetted in a barrel container that is driven to rotate, it cannot be applied to an existing barrel plating apparatus, and the complexity of the mechanism is unavoidable even when a new work is made. On the other hand, when ejecting from the outside of the barrel container, liquid ejection cannot properly expect the liquid to be blown to the floating work, and the floating work cannot be expected to settle. In response to these problems, gas injection is used in the present embodiment, so that the plating solution is not bubbled and the floating part of the existing barrel container is utilized from the outside of the barrel container. Sedimentation can be promoted, the mechanism is not complicated, and it can be easily applied to an existing barrel plating apparatus. Further, by providing the gas injection means above the outside of the barrel container, the gas injection means is not immersed in the plating solution, and the rebound of the plating solution hardly adheres to the gas injection means until it passes through the barrel container. Therefore, even when plating is performed a plurality of times using different plating solutions to form multiple plating layers, there is no possibility that the plating solution adheres to the gas jetting means and that it is brought into the next plating step. In addition, if the liquid is ejected from the outside of the barrel container, a part of the ejected liquid may collide with the barrel container and bounce off and adhere to the gas ejecting means. Nor. Therefore, the liquid adhering to the gas jetting means is not likely to be brought into the next plating process. Further, if the gas injection means is provided outside the barrel container, it is possible to select fixing the gas injection means to a part of the barrel container support means. In that case, due to the nature of the barrel container support means, the gas injection means is always used. It can be arranged at a fixed position / posture with respect to the barrel container.

以上、好ましい実施の形態を参照して本発明の内容を具体的に説明したが、本発明の基本的技術思想及び教示に基づいて、当業者であれば、種々の改変態様を採り得ることは自明である。   Although the contents of the present invention have been specifically described with reference to the preferred embodiments, various modifications can be made by those skilled in the art based on the basic technical idea and teachings of the present invention. It is self-explanatory.

まず、上述した実施の形態は、処理液としてめっき液が用いられるバレルめっき装置として説明したが、本発明に係るバレル装置、すなわちバレル容器を持った装置は、これに限定されるものではない。本発明に係るバレル装置は、多数のワークを収容し、バレル容器を回転させることにより行う処理であって、容器内でワークが浮上しないことが処理成績において重要となる処理を行うものに広く適用することができる。したがって、例えば、処理液として洗浄液が用いられる洗浄工程に使用されるバレル洗浄装置として実施することもできる。   First, although the above-described embodiment has been described as a barrel plating apparatus in which a plating solution is used as a processing solution, the barrel apparatus according to the present invention, that is, an apparatus having a barrel container is not limited to this. The barrel apparatus according to the present invention is a process that is performed by accommodating a large number of workpieces and rotating the barrel container, and is widely applied to processes that are important in processing results that the workpiece does not float in the container. can do. Therefore, for example, it can also be implemented as a barrel cleaning apparatus used in a cleaning process in which a cleaning liquid is used as a processing liquid.

気体噴射手段としては、ノズルを複数設け、ノズルそれぞれを往復移動させるようにしてもよい。あるいは、気体噴射手段として、多数のノズルを設けるか、大型の単体ノズルに複数の噴射口を設けておき、ノズルを移動させることなく気体噴射してもよい。何れにしても、そのようにすることで、液面のどこに浮上してくるか想定しづらい浮上ワークに対して、満遍なく気体噴射し、より確実に気体を吹き付けることができる。   As the gas injection means, a plurality of nozzles may be provided, and each nozzle may be reciprocated. Alternatively, a large number of nozzles may be provided as gas injection means, or a plurality of injection ports may be provided in a large single nozzle, and gas injection may be performed without moving the nozzles. In any case, by doing so, it is possible to inject gas evenly and blow the gas more reliably to the floating work which is difficult to assume where on the liquid surface it will float.

また、めっき処理が始まるとめっき化学反応により気泡が発生しやすく、その気泡に起因してめっき処理中にワークが浮揚することも生じうる。本発明に係るバレルめっき装置は、めっき処理が始まった後に、気体噴射によりワークを沈降させるように実施された装置も含む。   Further, when the plating process starts, bubbles are likely to be generated by a plating chemical reaction, and the workpiece may be floated during the plating process due to the bubbles. The barrel plating apparatus according to the present invention also includes an apparatus that is implemented so as to sink the workpiece by gas injection after the plating process is started.

本発明に係るバレル装置に用いられるバレル容器は、バレル容器の内側に液面が存在するようにされた容器であれば、上述した実施の形態のバレル容器に限定されるものではない。よって、例えば、回転軸が水平方向に対し傾斜しており、バレル容器の上部が斜め上方に向けて開口する、いわゆる傾斜バレル容器を有して実施されていてもよい。   The barrel container used in the barrel apparatus according to the present invention is not limited to the barrel container of the above-described embodiment as long as the liquid level is present inside the barrel container. Therefore, for example, the rotation axis may be inclined with respect to the horizontal direction, and a so-called inclined barrel container in which an upper portion of the barrel container opens obliquely upward may be used.
