Description

本発明は、液状薬剤をワークに塗布して塗布製品を製造する方法及び塗布装置に関する。特に、加工前の鋳造品（切削加工用鋳物）、鍛造品素材、プレス素材等の金属パーツに防錆油を塗布して塗布製品（半製品）を製造するのに適した新規な方法及び塗布装置に係る発明である。   The present invention relates to a method and a coating apparatus for manufacturing a coated product by applying a liquid medicine to a workpiece. In particular, a new method and coating suitable for producing coated products (semi-finished products) by applying rust-preventive oil to metal parts such as cast products before cutting (castings for cutting), forged materials, press materials, etc. It is an invention related to the apparatus.

ここでは、切削加工用鋳物を例に採り説明するが、これに限られるものではない。   Here, description will be made by taking a casting for machining as an example, but the present invention is not limited to this.

機械部品素材、自動車用部品素材として使用される切削加工用鋳物は、貯蔵中に錆が発生する。このため、通常、切削加工用鋳物（ワーク）には防錆油を塗布する（特許文献１段落０００７等参照）。   Castings for machining used as machine component materials and automotive component materials are rusted during storage. For this reason, a rust preventive oil is normally apply | coated to the casting (work) for cutting (refer patent document 1 paragraph 0007 grade | etc.,).

そして、防錆油の塗布は、一般的に浸漬やスプレー等の手段によって行っていた。しかし、鋳物材料表面は凹凸（特に隅部）が多く、均一に塗布することが困難であった（特許文献１段落０００３等参照）。   And application | coating of antirust oil was generally performed by means, such as immersion and a spray. However, the surface of the casting material has many irregularities (particularly corners), and it has been difficult to apply uniformly (see Patent Document 1, paragraph 0003, etc.).

特に、油性（Ｏ／Ｗエマルションを含む。）の場合、通常の塗布方法では、ワークに対する均一塗布が困難であるとされていた。完全な防錆油塗布効果を確保するためには、厚めに塗ったり、重ね塗りをしたりする必要があった。   In particular, in the case of oiliness (including O / W emulsion), it has been said that uniform coating on a workpiece is difficult by a normal coating method. In order to ensure a complete rust preventive oil application effect, it was necessary to apply thickly or overcoat.

このため、防錆油の過剰塗布となった場合は、後の切削加工等における取扱い性・作業性に悪影響を与えるとともに、防錆油の大量消費につながった。また、スプレー塗布の場合は、スプレー塗布により発生するミスト（分散質が液体のエーロゾル：霧）の飛散があり、作業者吸い込み防止等のための特別な対策を必要とした。   For this reason, excessive application of rust-preventing oil adversely affects handling and workability in subsequent cutting and the like, leading to a large consumption of rust-preventing oil. In the case of spray application, mist (dispersed liquid aerosol: mist) generated by spray application is scattered, requiring special measures to prevent workers from sucking.

本発明の特許性に影響を与えるものではないが、切削加工用鋳物の防錆塗膜に関連する先行技術文献として、下記特許文献１・２等が存在する。
特開平６−１５２２５号公報 特開平１０−４２５号公報 Although not affecting the patentability of the present invention, the following Patent Documents 1 and 2 and the like exist as prior art documents related to the anticorrosive coating film of the casting for cutting.
JP-A-6-15225 Japanese Patent Laid-Open No. 10-425

本発明は、上記にかんがみて、凹凸を有するワークに対して、防錆油等の油性薬液を可及的に均一かつ薄膜である塗膜を形成可能な塗布製品の製造方法及び油性薬液に適した連続塗付装置を提供することを目的（課題）とする。   In view of the above, the present invention is suitable for a method for manufacturing a coated product and an oily chemical solution capable of forming a coating film that is as thin and thin as possible with an oily chemical solution such as rust preventive oil on a workpiece having irregularities. Another object is to provide a continuous coating apparatus.

本発明の他の目的（課題）は、上記目的（課題）と共に、塗布作業環境の改善に寄与することができる塗布製品の製造方法及び油性薬液に適した連続塗付装置を提供することにある。   Another object (problem) of the present invention is to provide a method for producing a coated product and a continuous coating apparatus suitable for an oily chemical solution that can contribute to the improvement of the coating work environment together with the above object (problem). .

本発明の塗布製品の製造方法は、上記課題を、下記構成により解決するものである。   The manufacturing method of the coated product of this invention solves the said subject with the following structure.

油性薬液をワークに塗布して塗布製品を製造する方法であって、
前記ワークをエア圧損が実質的に発生しない穴明きコンベヤで搬送するとともに、
前記穴明きコンベヤ及びワークを前記油性薬液で濡らした後、
前記穴明きコンベヤに向かうエアカーテンを噴射させて、前記ワークの滴切りを行うとともに前記油性薬液をミスト化させることを特徴とする。 A method for producing a coated product by applying an oily chemical to a workpiece,
While transporting the work by a perforated conveyor that does not substantially cause air pressure loss,
After wetting the perforated conveyor and workpiece with the oily chemical,
The air curtain heading toward the perforated conveyor is sprayed to cut the workpiece and to make the oily chemical liquid mist.

エアカーテンで滴切りしたワークをミスト薬液中を通過させる結果となり、余剰な付着薬液が除去されると同時に付着不良部位にはミストにより薬液が付着して、液状薬液の垂れが発生するような厚塗り部が発生することなく、均一かつ薄膜の塗膜を有する塗布製品（防錆油塗布製品）を製造可能となる。   Thickness that results in the work drip-cut by the air curtain passing through the mist chemical solution, so that excess adhered chemical solution is removed and at the same time the chemical solution adheres to the poorly adhered part due to mist and dripping of the liquid chemical solution occurs. A coated product (rust-preventive oil coated product) having a uniform and thin film coating can be produced without the occurrence of a coating portion.

上記塗布製品の製造方法において、前記濡らしを上方からの滴下及び下方からの噴射により行うことが望ましい。穴明きコンベヤやワークを浸漬濡らしする場合に比して、濡らし量（油性薬液）の調整が容易となる。   In the manufacturing method of the coated product, it is preferable that the wetting is performed by dropping from above and jetting from below. The amount of wetting (oil-based chemical solution) can be easily adjusted as compared with the case where a perforated conveyor or workpiece is immersed and wetted.

上記塗布製品の製造方法において、油性薬液の濡らし及びミスト化を、前記ワークの搬入・搬出口が搬入・搬出時のみ開となる閉鎖状の第１・第２処理室で行うとともに、前記濡らし及び前記滴切りで発生する余剰の薬液（ミスト状態のものを含む。）を自重落下（自由落下）させて回収し、前記濡らしに循環使用する構成とすることが望ましい。使用されなかった余剰油性薬液を拡散させずに循環使用する結果となり、作業環境の改善に寄与する。   In the manufacturing method of the coated product, wetting and misting of the oily chemical is performed in the closed first and second processing chambers in which the loading / unloading port of the workpiece is opened only when loading / unloading, and the wetting and It is desirable that a surplus chemical solution (including a mist state) generated by the dripping is recovered by dropping it by its own weight (free fall) and circulating for use in the wetting. As a result, the excess oily chemical solution that has not been used is recycled without being diffused, which contributes to the improvement of the working environment.

上記構成において、さらに、前記第１・２処理室に亘って覆い空間層を形成し、該ジャケット空間層を介してミスト回収を行うことが望ましい。第１・２処理室で発生するミストの系外への拡散が確実に阻止でき、さらに、作業環境の改善に寄与する。   In the above-described configuration, it is preferable that a covering space layer is formed over the first and second processing chambers, and mist recovery is performed through the jacket space layer. The diffusion of mist generated in the first and second processing chambers to the outside of the system can be surely prevented, and further contributes to the improvement of the working environment.

上記各構成の塗布製品の製造方法は、金属パーツの防錆油塗布製品の製造に適用することが本発明の効果が顕著となり好ましい。   It is preferable that the method for producing a coated product having the above-described configuration is applied to the production of a rust-preventive oil-coated product for metal parts because the effect of the present invention is remarkable.

上記各構成の塗布製品の製造方法に好適なワークの連続塗布装置の構成は下記の如くになる。   The structure of the continuous coating apparatus for workpieces suitable for the manufacturing method of the coated products having the above-described structures is as follows.

前記第１・２処理室の各ワークの搬入・搬出口には、コンベヤ上のワークが通過可能なカーテンで閉じられ、さらに、
前記１・２処理室の下方開口に対向して塗液タンクを備え、該塗液タンクは前記塗液供給配管とポンプを介して循環可能に接続されていることを特徴とする。 A continuous application device for continuously applying a coating liquid to a work (object to be coated),
A net-type conveyor for transferring workpieces, and a first processing chamber and a second processing chamber arranged along the workpiece transfer direction so that the workpiece transfer surface of the conveyor penetrates,
In the first processing chamber, a dripping nozzle and / or a spray nozzle (spray nozzle) heading toward the conveyor connected to the coating liquid supply pipe are provided,
The second processing chamber includes a slit nozzle capable of forming an air curtain toward the conveyor, and
The loading / unloading port of each workpiece in the first and second processing chambers is closed with a curtain through which the workpiece on the conveyor can pass,
A coating liquid tank is provided opposite the lower opening of the first and second processing chambers, and the coating liquid tank is connected to the coating liquid supply pipe through a pump so as to be circulated.

上記構成のワークの連続塗布装置は、前記第１・第２処理室の外側にジャケット室を形成し、該ジャケット室をミスト回収器と接続する構成とすることが望ましい。作業環境の改善により寄与する。   It is preferable that the continuous coating apparatus for a workpiece having the above-described configuration is configured such that a jacket chamber is formed outside the first and second processing chambers, and the jacket chamber is connected to a mist collector. Contribute by improving the working environment.

本発明の連続塗布装置は、油性薬液（例えば、油性防錆油）の塗布装置に適用することが本発明の効果が顕著となり望ましい。   It is desirable that the continuous coating apparatus of the present invention is applied to a coating apparatus for an oily chemical solution (for example, oily rust preventive oil) because the effect of the present invention is remarkable.

（Ａ）以下、本発明の一実施形態である防錆油連続塗布装置について、説明をする。   (A) Hereinafter, the rust preventive oil continuous coating apparatus which is one embodiment of the present invention will be described.

基本的には、鋳造品（ワーク）Ｗに防錆油の塗付を連続的に施すための連続塗布処理装置である。本実施形態では、ワークとして、切削加工前の鋳造品を例に採り、防錆油として油性防錆油（油性薬液）を例に採る。   Basically, it is a continuous coating treatment device for continuously applying rust preventive oil to a cast product (workpiece) W. In the present embodiment, a cast product before cutting is taken as an example of the workpiece, and an oil-based rust-proof oil (oil-based chemical solution) is taken as an example of the rust-proof oil.

ネット型コンベヤ１２と、該ネット型コンベヤ１２の搬送面１８の上側に配されるそれぞれ閉鎖状の第１処理室１４及び第２処理室１６とを備えている。   A net type conveyor 12 and a closed first processing chamber 14 and a second processing chamber 16 disposed above the transfer surface 18 of the net type conveyor 12 are provided.

ここで、ネット型コンベヤ（穴明きコンベヤ）１２は、後述の下方からのエア噴射により、コンベヤ１２を濡らした（コンベヤ１２に付着した）油性防錆油がミスト化可能な開口率を備えているものなら特に限定されない。穴明きコンベヤ１２は、通常、エア圧損が実質的に発生しないものとし、代表的には、ネット型コンベヤを使用できる。具体的には、開口率３０〜９０％、望ましくは６０〜８０％のものを使用する。開口率が低過ぎてエアカーテンによる、コンベヤ等を濡らした（付着した）防錆油のミスト化が困難であり、開口率が高すぎるワーク搬送のための強度を確保し難くなる。   Here, the net-type conveyor (perforated conveyor) 12 has an opening ratio that allows oil-based rust preventive oil that has wetted the conveyor 12 (attached to the conveyor 12) to be misted by air injection from below. There is no particular limitation as long as it is. The perforated conveyor 12 is normally assumed to have substantially no air pressure loss, and a net type conveyor can be typically used. Specifically, an aperture ratio of 30 to 90%, preferably 60 to 80% is used. It is difficult to make the rust-proof oil mist that wets (adheres) the conveyor or the like with the air curtain because the aperture ratio is too low, and it is difficult to secure the strength for conveying the workpiece with an aperture ratio that is too high.

具体的には、ワイヤーネット１８の両側に駆動チェーン２０、２０を取付け、全長をエンドレスにしたものを使用する。そして、枠組みフレーム２２の前後及び中間に、搬送方向に直交しかつ水平に取り付けた前後ホイール（一体回転するスプロケット２４ａとドラム２４ｂとからなる：以下同じ）２４、２４Ａ及び中間ホイール２５、テンションホイール２５Ａの各スプロケット２４ａ、・・・にチェーン２０、２０をかみ合わせてある。そして、駆動側（前側）のホイール２４の回転軸がギアドモータ（電動機）２７の出力軸と連結されている。そして、ギアドモータ２７を起動させることにより、ネット型コンベヤ１２を作動する。また、チェーンの張り調整は、アジャストボルト（図示せず）により手動で行う。   Specifically, the drive chains 20 and 20 are attached to both sides of the wire net 18 and the total length is made endless. Front and rear wheels (consisting of a sprocket 24a and a drum 24b that rotate together; the same applies hereinafter) 24, 24A, an intermediate wheel 25, and a tension wheel 25A that are attached to the front and rear and the middle of the frame 22 perpendicularly to the conveyance direction and horizontally. The chain 20 is engaged with each of the sprockets 24a,. The rotating shaft of the driving side (front side) wheel 24 is connected to the output shaft of the geared motor (electric motor) 27. Then, the net type conveyor 12 is operated by starting the geared motor 27. The chain tension is adjusted manually with an adjusting bolt (not shown).

第１処理室１４では、ネット型コンベヤ１２のワイヤーネット（搬送面）１８の上下に防錆油噴霧パイプ（防錆油供給手段）３０、３０Ａが配してある。   In the first processing chamber 14, antirust oil spray pipes (antirust oil supply means) 30 and 30 </ b> A are arranged above and below a wire net (conveying surface) 18 of the net type conveyor 12.

防錆油噴霧パイプ３０、３０Ａは、本実施形態では、パイプ３０ａに複数の噴霧ノズル３０ｂを所定ピッチで並列に形成したものである。油性防錆油の専用機とするときは、上方の錆油噴霧パイプは、噴霧パイプである必要はなく、防錆油滴下パイプでよい。   In the present embodiment, the rust preventive oil spray pipes 30 and 30A are formed by forming a plurality of spray nozzles 30b in parallel at a predetermined pitch on the pipe 30a. When using a dedicated machine for oil-based rust preventive oil, the upper rust oil spray pipe need not be a spray pipe, and may be a rust preventive oil dripping pipe.

これらの防錆油噴霧パイプ３０、３０Ａは、防錆油タンク３２と循環用ポンプ３４を備えた油供給（循環）配管３６を介して接続する。また、防錆油タンク３２は、上方が開口しており、噴霧後の余剰防錆油が自由乃至自重落下することにより回収可能となっている。なお、防錆油タンク３２の底部にはドレン抜き３８があり、側部には油量ゲージ４０が取り付けられている。   These antirust oil spray pipes 30 and 30A are connected via an oil supply (circulation) pipe 36 provided with an antirust oil tank 32 and a circulation pump 34. Moreover, the upper part of the rust preventive oil tank 32 is open, and the excess rust preventive oil after spraying can be recovered by free or self-weight fall. In addition, the drain part 38 is provided in the bottom part of the antirust oil tank 32, and the oil quantity gauge 40 is attached to the side part.

第２処理室１６では、ワイヤーネット（搬送面）１８の上下にエア噴射パイプ４２が配されている。各エア噴射パイプ４２は、第２処理室１６の上方に配されたリングブロワ（エア供給手段：気体輸送機）４４と、送風ダクト４６を介して接続する。   In the second processing chamber 16, air injection pipes 42 are arranged above and below the wire net (conveying surface) 18. Each air injection pipe 42 is connected to a ring blower (air supply means: gas transporter) 44 disposed above the second processing chamber 16 via a blower duct 46.

エア噴射パイプ４２は、本実施形態では、パイプ４２ａに、パイプ４２ａの母線に沿ってスリット（フラット）ノズル４２ｂを備え、エア噴射時、エアカーテンを形成可能なものである。   In the present embodiment, the air injection pipe 42 includes a slit (flat) nozzle 42b along the generatrix of the pipe 42a in the pipe 42a, and can form an air curtain during air injection.

この第２処理室１６では、スリットノズルで形成されるエアカーテン（エアブロー）により、ワークＷに隅部（窪み）に基づく液溜り等の過剰付着部を除去する滴切りの作用を奏するとともに、ワイヤーネット１８及びワークＷを濡らしている（付着している）防錆油をミスト化する作用を奏する。該ミスト中をワークＷが通過することにより、防錆油付着不良部位に防錆油が付着してワークＷに均一な防錆油薄膜が形成される。   In the second processing chamber 16, the air curtain (air blow) formed by the slit nozzle has a drip-cutting action for removing excessive adhesion portions such as a liquid pool based on the corners (dents) on the work W, and a wire The net 18 and the work W are wetted (attached), and the effect of mist-forming the rust preventive oil is achieved. When the workpiece W passes through the mist, the rust-preventing oil adheres to the portion where the rust-preventing oil adhesion is poor, and a uniform rust-preventing oil thin film is formed on the workpiece W.

ここで、エア噴射パイプ（エアカーテン形成手段）４２、４２Ａの位置・エア噴射の向きは、滴切り／ミスト化の見地から、変えてある。すなわち、上方のエア噴射パイプ４２はノズル向きが直下（垂直）であるが、下方のエア噴射パイプ４２Ａは、上方のものよりワークの搬送方向側に位置させ、かつ、スリットノズル４２ｂの搬送方向に対向するような所定の仰角を有して配してある。   Here, the positions of the air injection pipes (air curtain forming means) 42 and 42A and the direction of the air injection are changed from the viewpoint of dropping / misting. That is, the nozzle direction of the upper air injection pipe 42 is directly below (vertical), but the lower air injection pipe 42A is positioned closer to the workpiece conveyance direction than the upper one, and in the conveyance direction of the slit nozzle 42b. It is arranged with a predetermined elevation angle so as to face each other.

しかし、このエア噴射ノズルの位置及び向き並びに形状は、製品や防錆油の種類により異なることがある。このため、図示しないが、最適な位置・方向を手動により調節可能としておくことが望ましい。   However, the position, orientation, and shape of the air injection nozzle may vary depending on the product and the type of rust preventive oil. For this reason, although not shown, it is desirable that the optimum position and direction can be manually adjusted.

上記第１処理室１４及び第２処理室１６は、本実施形態ではワーク搬送方向に配設した分離独立室とされている（隔壁のみの連続する独立室であってもよい。）。すなわち、ワイヤーネット（搬送面）１８直上のワーク入口・出口を、それぞれ、撓み可能なスリットカーテン４８で閉じてある。また、第１処理室１４及び第２処理室１６が連続しているため、第１処理室１４と第２処理室１６の境界部は一枚のスリットカーテン４８で閉じる。   In the present embodiment, the first processing chamber 14 and the second processing chamber 16 are separated independent chambers arranged in the workpiece conveyance direction (may be continuous independent chambers having only partition walls). That is, the workpiece entrance / exit immediately above the wire net (conveying surface) 18 is closed by a deflectable slit curtain 48. Further, since the first processing chamber 14 and the second processing chamber 16 are continuous, the boundary between the first processing chamber 14 and the second processing chamber 16 is closed by a single slit curtain 48.

図例では、スリットカーテン（可撓性カーテン）４８は、ゴム板製で多数のスリットを形成したものであるが、搬送面１８を移動するワークが円滑に通過可能であればスリットカーテンに限られない。すなわち、ミストの系外（機外）への逸散を抑制できれば、可撓性カーテンさらにはエアカーテンでも問題がない。   In the illustrated example, the slit curtain (flexible curtain) 48 is made of a rubber plate and formed with a large number of slits. However, the slit curtain (flexible curtain) 48 is limited to the slit curtain as long as the workpiece moving on the conveying surface 18 can pass smoothly. Absent. That is, there is no problem even with a flexible curtain or even an air curtain as long as the mist can be prevented from escaping to the outside (outside the machine).

さらに、第１処理室１４及び第２処理室１６に亘って、それらの周囲および上方を覆うジャケットボックス５０で覆い、該ジャケットボックス５０の上にミスト捕集器（回収器）５２を配してある。該ミスト捕集器５２は、フィルタでミストを捕集可能となっており、フィルタの目詰まり時には、交換可能となっている。   Further, the first processing chamber 14 and the second processing chamber 16 are covered with a jacket box 50 that covers the periphery and the upper portion thereof, and a mist collector (collector) 52 is disposed on the jacket box 50. is there. The mist collector 52 can collect mist with a filter, and can be replaced when the filter is clogged.

なお、防錆油タンク（薬液タンク）３２の下方には、オイルパン５４を配してある。オイルパン５４は、装置部からの油漏れ等で装置外へ漏出した防錆油を受けて、床面に油が流出するのを防止するためである。   An oil pan 54 is disposed below the rust preventive oil tank (chemical solution tank) 32. The oil pan 54 receives rust preventive oil leaked out of the apparatus due to oil leakage from the apparatus section, and prevents the oil from flowing out to the floor surface.

また、本装置の製品排出位置には、光電センサー５６により処理個数を自動カウントできるようになっている。   Further, the processing number can be automatically counted by the photoelectric sensor 56 at the product discharge position of the apparatus.

なお、第１処理室１４、第２処理室１６およびジャケットボックス５０は、それぞれ、側壁（前後壁）は、透明板からなる閉鎖蓋（図示せず）が取り付けられ、防錆油の噴霧状態、ミスト化状態を観察し、かつ、ノズルの角度換えやノズル替えが可能となっている。   The first processing chamber 14, the second processing chamber 16, and the jacket box 50 have side walls (front and rear walls) each provided with a closure lid (not shown) made of a transparent plate, and sprayed with rust preventive oil. The mist state can be observed, and the nozzle angle and nozzle can be changed.

（Ｂ）次に、上記装置を使用しての塗装製品（油性の防錆油塗膜形成製品）の製造方法について、説明する。   (B) Next, the manufacturing method of the coated product (oil-based antirust oil coating film formation product) using the said apparatus is demonstrated.

前準備として、防錆油タンク３２には、所定量の防錆油を投入しておく。   As a preparatory step, a predetermined amount of rust preventive oil is put into the rust preventive oil tank 32.

１）ワーク搬送用のネット型コンベヤ（穴明きコンベヤ）１２を始動する。   1) Start the net type conveyor (perforated conveyor) 12 for conveying the workpiece.

２）循環用ポンプ３４を始動して、噴射油量の調節を行う。滴下可能であればよく、通常、ポンプ吐出圧は０．０１〜０．８MPaの範囲とする。なお、この場合の油性防錆油のワイヤーネット１ｍ2あたりの滴下量は、防錆油・ワークの種類に応じて異なるが、例えば、１０〜１００ｇとする。 2) Start circulation pump 34 to adjust the amount of injected oil. What is necessary is just to be able to be dripped, and the pump discharge pressure is usually in the range of 0.01 to 0.8 MPa. In addition, although the dripping amount per 1 m < 2 > of wire-based oil-based rust preventive oil in this case changes according to the kind of rust preventive oil and a workpiece | work, it is 10-100 g, for example.

３）ブロワー（気体輸送機）４４を始動して、風量の調節を行う。通常、ノズル吐出圧５〜３０kpaの範囲とする。   3) Start the blower (gas transporter) 44 and adjust the air volume. Usually, the nozzle discharge pressure is in the range of 5 to 30 kpa.

４）ミスト捕集器５２を始動して、フィルタの目詰まりを点検する。   4) Start the mist collector 52 and check the filter for clogging.

５）鋳物製品（ワーク）Ｗを、ネット型コンベヤ１２の上に載せ、ワーク装置内へ搬入する。すると、第１処理室１４では、ワイヤーネット１８及びワークＷが防錆油で濡らされる。さらに、第２処理室１６で、エアカーテンによりワークＷが滴切りされるとともに防錆油がミスト化されて、ワークはミスト雰囲気に曝される。すなわち、滴切りにより、過剰付着部位においては余剰防錆油が除去されると共に、付着不良部位においてはミスト化された防錆油が付着して、均一で薄肉の防錆油塗膜が形成される。そして、ワークＷは、光電センサー５６を介して個数をカウントされながら装置外へ搬出される。   5) A cast product (work) W is placed on the net type conveyor 12 and carried into the work device. Then, in the 1st processing chamber 14, the wire net 18 and the workpiece | work W are wetted with antirust oil. Further, in the second processing chamber 16, the work W is dropped by the air curtain and the rust preventive oil is made mist, so that the work is exposed to the mist atmosphere. That is, by dripping, the excess rust preventive oil is removed at the excessive adhesion site, and the misted rust preventive oil is adhered at the poor adhesion site to form a uniform, thin-walled rust oil coating. The Then, the workpiece W is carried out of the apparatus while counting the number via the photoelectric sensor 56.

６）防錆油は、防錆油タンク３２に貯蔵されており、防錆油タンク３２から循環用ポンプ３４により油供給配管３６を介して防錆油噴霧パイプ（防錆油供給手段）３０から噴射されてワイヤーネット１８及びワークＷを濡らす。そして、ワイヤーネット１８及びワークに付着しない余剰の防錆油は、落下して防錆油タンク３２で回収されて、循環使用される。   6) The rust preventive oil is stored in the rust preventive oil tank 32, and from the rust preventive oil spray pipe (rust preventive oil supply means) 30 from the rust preventive oil tank 32 through the oil supply pipe 36 by the circulation pump 34. The wire net 18 and the workpiece W are wetted by being sprayed. And the excessive rust preventive oil which does not adhere to the wire net | network 18 and a workpiece | work falls, and is collect | recovered with the rust preventive oil tank 32, and is circulated and used.

７）防錆油の第１処理室１４及び第２処理室１６で発生する防錆油ミストは、第１・第２処理室１４、１６に亘って覆ったジャケットボックス５０で形成された外周のミスト導通層（覆い空間層）５１からダクトを介してミスト捕集器５２で吸引捕集されて大気へ放出される。直接、第２処理室１６から吸引すると、ミストが希薄化してミストによる均一かつ薄肉の油膜をワーク面に形成し難くなる。   7) The rust preventive oil mist generated in the first treatment chamber 14 and the second treatment chamber 16 of the rust preventive oil is formed on the outer periphery formed by the jacket box 50 covered over the first and second treatment chambers 14 and 16. It is sucked and collected by the mist collector 52 through the duct from the mist conduction layer (covering space layer) 51 and released to the atmosphere. When sucked directly from the second processing chamber 16, the mist is diluted and it becomes difficult to form a uniform and thin oil film on the workpiece surface by the mist.

（Ｃ）上記構成において、ミストが形成される第２処理室から直接、ミストダクトを介してミスト捕集を行うことも考えられるが、ミスト濃度が希薄になって、所定の防錆油膜厚をワークに形成できないおそれがある。   (C) In the above configuration, it is conceivable to collect the mist directly from the second processing chamber where the mist is formed through the mist duct, but the mist concentration becomes dilute and the predetermined rust preventive oil film thickness is increased. There is a possibility that it cannot be formed on the workpiece.

さらに、ネット型コンベヤのワイヤーネットの代わりに、強度を確保できかつ濡らし可能なら、パンチングメタルであってもよい。   Further, instead of the wire net of the net type conveyor, punching metal may be used as long as the strength can be ensured and wetted.

上記では防錆油が油性の場合を例にとって説明したが、防錆油が水性の場合で本発明の装置を使用した場合は、下記の如くになる。   In the above description, the case where the rust preventive oil is oily has been described as an example. However, when the rust preventive oil is aqueous and the apparatus of the present invention is used, the following is obtained.

循環用ポンプ３４の吐出圧を高圧として、上・下防錆油供給パイプ３０、３０Ａから多量の防錆油を噴射して、第１処理室１４で、ワークＷに対して十分な量の防錆油を塗布後、第２処理室１６でワークＷに過剰に付着した水性防錆油を、上下のエア噴射パイプ４２で形成されるエアカーテンにより滴切りを行って、均一な薄膜塗膜を形成して、塗装製品とする。なお、この場合の水性防錆油のワイヤーネット１ｍ2あたりの噴霧量（噴射量）は、防錆油・ワークの種類に応じて異なるが、例えば、２００〜１０００ｇとする。 With the discharge pressure of the circulation pump 34 set to a high pressure, a large amount of anti-rust oil is injected from the upper and lower anti-rust oil supply pipes 30 and 30A, and a sufficient amount of anti-rust is applied to the workpiece W in the first processing chamber 14. After applying the rust oil, the aqueous rust preventive oil excessively adhered to the workpiece W in the second processing chamber 16 is dropped by an air curtain formed by the upper and lower air injection pipes 42 to form a uniform thin film coating film. Form a coated product. In this case, the spray amount (injection amount) of the water-based anti-rust oil per 1 m 2 of the wire net varies depending on the type of the anti-rust oil / work, but is, for example, 200 to 1000 g.
