Description

本発明は塗装ブース内に噴霧された塗料ミストを直接バッフル板に衝突させることにより付着させ、塗料を捕集する方式の乾式塗装ブースに使用するバッフル板とその取付け板に関する。   The present invention relates to a baffle plate used in a dry painting booth of a type in which paint mist sprayed in a coating booth is directly adhered to a baffle plate and collected to collect the paint, and its mounting plate.

塗装ブースは塗料ミストの捕集方式により大きく分けて乾式と湿式に分類され、乾式の場合は主としてフィルタを用いて捕捉する方式とバッフル板と呼ばれる衝突板により塗料の粘着力によって捕捉する方式が知られている。この場合、フィルタによる場合は目を細かくすれば細かい塗料ミストまでも捕集できるが、通常の塗料の場合には粘着力が残っており、すぐに目詰まりを起して使用不能になる。一方、バッフル板を用いる場合は気流通路が広く取れるため目詰まりも少なくフィルタを用いて細くする方式に比べ長期にわたって使用できる利点がある。   Coating booths are roughly classified into dry and wet types according to the paint mist collection method. In the case of dry type, there are two types: the trapping method using a filter and the trapping method called a baffle plate using the adhesive force of the paint. It has been. In this case, if the filter is used, even fine paint mist can be collected if the eyes are made fine, but in the case of a normal paint, the adhesive force remains, causing clogging immediately and making it unusable. On the other hand, when a baffle plate is used, there is an advantage that it can be used for a long period of time compared to a method of narrowing using a filter with less clogging because the air flow path is wide.

一般的に乾式の塗装ブースは取扱い管理が容易なため広く採用されており、その代表的な装置として特公昭５２−３３８２５号公報や実公昭５３−４９０９６号公報に見られる塗装ブースがある。図９に汎用の乾式の塗装ブースの正面の概略を示している。また、図１０にはその塗装ブースで使用されているバッフル板の取付け構造が示されている。   In general, dry painting booths are widely adopted because they are easy to handle and manage, and typical examples of such booths are those shown in Japanese Patent Publication No. 52-33825 and Japanese Utility Model Publication No. 53-49096. FIG. 9 shows a schematic front view of a general-purpose dry painting booth. FIG. 10 shows the baffle plate mounting structure used in the painting booth.

ここに示されているように、塗料ミストを捕集するバッフル板Ａは焼却が容易な段ボール紙の如き可燃性の材質で、断面がコ字状に折り曲げられたチャンネル形状をしており、これらの内側を互いに向かい合わせるように、且つ隙間を形成して多数併設することによって曲折した気流通路を通過する間に塗料ミストが効率的に捕集される構成になっている。   As shown here, the baffle plate A that collects the paint mist is a combustible material such as corrugated paper that is easy to incinerate, and has a channel shape whose cross section is bent in a U-shape. The paint mist is efficiently collected while passing through the bent airflow passage by forming a large number of gaps so as to face each other inside.

そしてバッフル板Ａは取り扱い上の適合性から、コ字状に折り曲げたバッフル板を５０ｃｍほどの長さに揃え、塗装ブース１の塗装室２前面の内側と外側に、折り曲げた側を向かい合わせるように且つ互い違いに組み込む構成がとられていた。従って、比較的小さい間口１ｍ幅の塗装ブースでも５２枚のバッフル板が使用されている。   For baffle plate A, the baffle plate folded in a U-shape is aligned to a length of about 50 cm, so that the folded side faces the inside and outside of the front of the painting chamber 2 of the painting booth 1 for suitability in handling. In addition, a configuration in which they are alternately installed was adopted. Therefore, 52 baffle plates are used even in a relatively small 1 m wide painting booth.

又、バッフル板Ａは段ボール基材表面に不織布を接着した１枚板をコ字状に折り曲げて、表裏面を交互に向き合わせて塗装ブース１の開口部に臨む取付け板Ｂに取り付けている。塗料ミストはコ字状の折曲部を通過する際、慣性力によりバッフル板Ａに衝突し，表面の不織布起毛に絡みつくことで塗料ミストの再飛散を防止しながら捕集している。   Further, the baffle plate A is attached to a mounting plate B facing the opening of the painting booth 1 by bending a single plate in which a nonwoven fabric is bonded to the surface of the corrugated cardboard substrate into a U shape and alternately facing the front and back surfaces. When the paint mist passes through the U-shaped bent portion, the paint mist collides with the baffle plate A due to the inertial force and is caught while preventing the paint mist from re-scattering by being entangled with the nonwoven fabric raising on the surface.

特公昭５２−３３８２５号公報Japanese Patent Publication No.52-33825 実公昭５３−４９０９６号公報Japanese Utility Model Publication No. 53-49096

バッフル板に付着した塗料は徐々に堆積し、次第に通気面積が狭くなり通気抵抗が増加すると吸引力が低下し塗装室内に噴霧された塗料ミストの吸引が十分に出来なくなり、いずれバッフル板を交換することになる。この場合、バッフル板は塗装ブースの開口部全面に組み込まれており、前記のように多数の交換が必要であり、その交換時には多くの手間と時間を要することになる。   The paint adhering to the baffle plate gradually accumulates, and if the ventilation area becomes narrower and the ventilation resistance increases, the suction force decreases and the paint mist sprayed into the paint chamber cannot be sufficiently sucked, and the baffle plate will be replaced. It will be. In this case, the baffle plate is incorporated in the entire surface of the opening of the painting booth, and as described above, a large number of replacements are necessary, and much time and effort are required for the replacement.

また、前記バッフル板は組み立ては簡単だが多数必要とし、コ字状に折り曲げる手間と時間がかかる難点がある。加えて、汚れたバッフル板を取り外すとき、付着した塗料によりバッフル板同士が固着したり、露出している取付け板の爪金具Ｃに塗料ミストが堆積してバッフル板の取外しが困難になる。また、付着塗料の除去の手間がかかりバッフル板の交換も時間がかかるといった問題がある。   In addition, the baffle plate is easy to assemble but requires a large number, and there is a problem that it takes time and effort to bend it into a U-shape. In addition, when removing the dirty baffle plates, the baffle plates adhere to each other due to the adhering paint, or paint mist accumulates on the claw fittings C of the exposed mounting plate, making it difficult to remove the baffle plates. In addition, there is a problem that it takes time to remove the adhering paint and replacement of the baffle plate takes time.

又、手前側（塗装室２側）のバッフル板Ａは取付け板の爪金具Ｃの間に挟んでいるだけのため、強風等で排気ダクトから外気が逆流すると、バッフル板が塗装室２側に押されて外れるおそれがあるため、別途バッフル板を押える固定部品（図９の符号Ｄで示す）が必要となりコストアップになる。   In addition, the baffle plate A on the front side (coating chamber 2 side) is only sandwiched between the claw fittings C of the mounting plate. Therefore, if the outside air flows backward from the exhaust duct due to strong winds, the baffle plate moves toward the coating chamber 2 side. Since there is a possibility that it will be pushed and removed, a fixing part (indicated by symbol D in FIG. 9) for separately pressing the baffle plate is required, resulting in an increase in cost.

本発明は上記の課題に対し、乾式塗装ブースのメンテナンス上で最も重要なバッフル板の取付けが確実でしかも交換が容易な、しかも汚れた部分のみのバッフル板の交換が可能なバッフル板およびその取付け板を提供することを目的とする。   In view of the above problems, the present invention provides a baffle plate that can be replaced with a baffle plate that is reliable and easy to replace, and that can be replaced only when it is dirty. The purpose is to provide a board.

A printed line for bending guidance is formed in the bent portion.

請求項６の発明は、請求項１乃至５のいずれかに記載のバッフル板であって、平板の縦長さを、バッフル板として塗装ブースの取付け板に取付けたときに上下に隙間の出来る寸法としたことを特徴とする。 The invention according to claim 6 is the baffle plate according to any one of claims 1 to 5, wherein the vertical length of the flat plate is a dimension that allows a vertical gap when the baffle plate is attached to the coating booth mounting plate. It is characterized by that.

請求項７の発明は、塗料ミスト捕集用バッフル板を塗装ブースに取付けるための取付け板であって、塗装ブースの前面開口部に複数列横架され、内側に向けて折り曲げられて形成される角柱状の２つの部屋に構成されたバッフル板の上下位置に形成された一対のスリットに嵌入する、２つの爪の先端角部をテーパー状に形成した一対の保持爪を突設したことを特徴とする。   The invention according to claim 7 is an attachment plate for attaching the baffle plate for collecting paint mist to the painting booth, and is formed by being laid in a plurality of rows at the front opening of the painting booth and bent inward.

本発明によれば、バッフル板を取付け板に差込むだけで取付け位置が自ずと定まるため取付け作業が容易で、取付け時間が短縮できる。また、取付け板が塗装ブース正面から見えないため、即ち、バッフル板により覆い隠され露出していないため、塗料が付着しにくく、取付け板からバッフル板を抜き取る際、従来構造にくらべ抵抗なく抜けるので交換時の手間が削減できる。平板の縦長さをバッフル板として取付け板に取り付けたときに上下に隙間の出来る寸法としたこと、バッフル板の上下端部に不織布が延伸された耳片を備えることでバッフル板同士が塗料ミストで固着しにくいため、汚れた部分のバッフル板のみの交換が可能となる。バッフル板の固定部品が不要になりコストダウンに寄与できる。   According to the present invention, since the mounting position is determined by simply inserting the baffle plate into the mounting plate, the mounting operation is easy and the mounting time can be shortened. In addition, since the mounting plate is not visible from the front of the paint booth, that is, it is not covered and exposed by the baffle plate, it is difficult for paint to adhere, and when the baffle plate is removed from the mounting plate, it will come out with less resistance than the conventional structure. Time and effort during replacement can be reduced. When the length of the flat plate is set as a baffle plate and attached to the mounting plate, it is dimensioned so that there is a gap between the top and bottom, and the baffle plate is provided with ear pieces with nonwoven fabric stretched on the upper and lower ends, so that the baffle plates are paint mist Since it is difficult to fix, it is possible to replace only the baffle plate in the dirty part. Baffle plate fixing parts are not required, which can contribute to cost reduction.

さらに、本発明のバッフル板は既存の塗装ブースにも取付けが可能である。即ち、既存の塗装ブースに取付けられているバッフル板の取付け板は、コ字状の爪が横列に多数突設された構成であるため、２つのコ字状の爪に本発明のバッフル板のスリットを差込むことで容易に取付けられる。但し、コ字状の爪間のピッチが本発明の取付爪のピッチと異なるためにブースの間口の左右に隙間が生ずるが、別途に隙間埋め部品を用いることで対処可能である。また、既存の取付け板と異なるのは、爪間のピッチの違いを除けば保持爪の形状のみであるため、既存の塗装ブースに対して取付け板単体の交換が可能である。   Furthermore, the baffle plate of the present invention can be attached to an existing painting booth. That is, the baffle plate mounting plate attached to the existing painting booth has a configuration in which a large number of U-shaped claws project in a row, so that the baffle plate of the present invention is formed on two U-shaped claws. It can be easily installed by inserting a slit. However, since the pitch between the U-shaped claws is different from the pitch of the mounting claws of the present invention, a gap is formed on the left and right sides of the booth front, but this can be dealt with by using a gap filling part separately. Further, since the only difference between the existing mounting plate and the shape of the holding claws is the difference in pitch between the claws, it is possible to replace the mounting plate alone with the existing coating booth.

以下、本発明を図示する実施形態により具体的に説明する。
図１は本発明を実施する塗装ブースの一例を示す一部切欠した正面図、図２は塗装ブースの内部を概略的に示す側面図である。乾式のバッフル板を使用した塗装ブース１は、作業を行う塗装室２の前面に塗料ミストを捕集するバッフル板１０が塗装室２の開口部を全面的に覆うよう設置され、その後部にフィルタ３が配置され、該フィルタ３の背部に設けた排気室４に排気扇５が接続されている。塗装室２内に噴霧され被塗装物（図示略）に塗着されなかった塗料ミストは、排気扇５による吸引気流にのって引かれ、バッフル板１０に衝突して捕捉され、さらに捕捉しきれない塗料ミストはバッフル板１０内に形成された曲折する隙間を通過しきれずに衝突して捕集される。バッフル板１０をわずかに通過した塗料ミストは背部のフィルタ３によって二次的に捕捉され、清浄化された空気が排気室４から排気扇５を通して外部に排気される。 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.
FIG. 1 is a partially cutaway front view showing an example of a painting booth for carrying out the present invention, and FIG. 2 is a side view schematically showing the interior of the painting booth. In the painting booth 1 using a dry baffle plate, a baffle plate 10 for collecting paint mist is installed in front of the painting chamber 2 where the work is performed so as to cover the entire opening of the painting chamber 2, and a filter is installed at the rear. 3 is disposed, and an exhaust fan 5 is connected to an exhaust chamber 4 provided at the back of the filter 3. The paint mist sprayed in the coating chamber 2 and not applied to the object to be coated (not shown) is drawn on the suction airflow by the exhaust fan 5, is collided with the baffle plate 10, and is further captured. The paint mist that cannot be broken is collected by colliding without passing through the bending gap formed in the baffle plate 10. The paint mist slightly passing through the baffle plate 10 is secondarily captured by the back filter 3, and the cleaned air is exhausted from the exhaust chamber 4 to the outside through the exhaust fan 5.

本発明におけるバッフル板１０は図３の展開図に全体の構成を示すように、矩形の段ボール紙製の平板１１よりなり、印刷面を有する表板１２を中心として左右に側板１３、１４が折込線１５により区画され、該側板１３、１４には塗料ミストが通過する通気窓１６が平板１１の長辺１１ａに沿って互いに重ならない位置に千鳥状に開けられている。   The baffle plate 10 according to the present invention is composed of a rectangular corrugated paper flat plate 11 as shown in the developed view of FIG. 3, and side plates 13 and 14 are folded right and left around a front plate 12 having a printing surface. A ventilation window 16 through which the paint mist passes is formed in a staggered pattern in the side plates 13 and 14 at positions where they do not overlap with each other along the long side 11a of the flat plate 11.

また、側板１３、１４に連設される底板１７、１８が折込線１５により区画され、該底板１７、１８には上下位置に長辺１１ａに対し直交するスリット１９が夫々形成されている。該スリット１９はＩ字形状に切り欠かれており、後述する取付け板に突設した保持爪が嵌入するようにしている。   In addition, bottom plates 17 and 18 connected to the side plates 13 and 14 are partitioned by a folding line 15, and slits 19 perpendicular to the long side 11 a are formed in the bottom plates 17 and 18 at the upper and lower positions, respectively. The slit 19 is cut out in an I-shape so that a holding claw projecting from a mounting plate, which will be described later, is fitted therein.

また、底板１７、１８に連設する内板２０、２１が折込線１５により区画され、該内板２０、２１には塗料ミストが通過する通気窓１６が長辺１１ａに沿って互いに重ならない位置に千鳥状に開けられている。   Further, inner plates 20 and 21 connected to the bottom plates 17 and 18 are partitioned by a folding line 15, and the ventilation plates 16 through which the paint mist passes are not overlapped with each other along the long side 11 a in the inner plates 20 and 21. It is opened in a staggered pattern.

また、折込線１５は折り曲げのためのミシン目加工し、更にはミシン目に合わせて線状に押し潰し加工をして折り癖をつけておくと組み立て作業が容易となる。また、折り曲げ部分に印刷線（図示略）を入れ折り曲げ箇所をわかり易くすることでもよい。   Further, if the folding line 15 is perforated for folding, and further crushed into a line according to the perforation, and then creased, the assembly work becomes easy. Alternatively, a printed line (not shown) may be inserted into the bent portion so that the bent portion can be easily understood.

尚、矩形の平板１１の表裏面には起毛製材料の不織布２２が通気窓を除く全面に接着されており、該不織布２２は平板１１の上下端部１１ｂ、１１ｃに延伸する耳片２２ａを伴っている。   In addition, the nonwoven fabric 22 of brushed material is adhere | attached on the whole surface except the ventilation window on the front and back of the rectangular flat plate 11, and this nonwoven fabric 22 is accompanied by the ear piece 22a extended to the upper-lower-end parts 11b and 11c of the flat plate 11. ing.

次に、バッフル板の組み立てを説明する。
図５に示すように、展開する平板状のバッフル板１０は表板１２の印刷面を外側にして側板１３、１４、底板１７、１８、内板２０、２１を区画する折込線１５を長辺１１ａに沿って平行に全てを内側に向けて谷折りして折り曲げ、最終的に四方が囲まれた角柱状の２つの部屋２３、２４を形成する。この角柱状の２つの部屋２３、２４は内部に通気室２３ａ、２４ａを備えた構成となる。 Next, assembly of the baffle plate will be described.
As shown in FIG. 5, the flat plate-like baffle plate 10 that is developed has a long side of the folding line 15 that divides the side plates 13, 14, the bottom plates 17, 18, and the inner plates 20, 21 with the printing surface of the front plate 12 facing outside. In parallel with 11a, all of them are folded inward and bent inward, and finally, two prismatic chambers 23 and 24 surrounded by four sides are formed. The two rectangular columnar chambers 23 and 24 are configured to have ventilation chambers 23a and 24a therein.

このようにして組み立てられたバッフル板１０は、塗装ブース１に設置された取付け板２５により固定される。取付け板２５は図８に示すように、塗装ブース１の前面開口部に複数列横架された金属製の板よりなり、前面の塗装室２側に向って突出する保持爪２６がバッフル板１０の底板１７、１８に形成したスリット１９に嵌入し、角柱状の２つの部屋２３、２４を備えたバッフル板１０は固定される。取付け板２５は上下の２列が１組をなし、バッフル板１０の上下位置に切り欠かれたＩ字形状の一対のスリット１９に保持爪２６が嵌入して固定される。また、該保持爪２６は取付け板２５に沿って横列に、取付けられるバッフル板の数分が突設されている。   The baffle plate 10 assembled in this way is fixed by a mounting plate 25 installed in the painting booth 1. As shown in FIG. 8, the mounting plate 25 is made of a metal plate horizontally mounted in the front opening portion of the painting booth 1, and the holding claw 26 protruding toward the painting chamber 2 side on the front surface has a baffle plate 10. The baffle plate 10 fitted with the slits 19 formed in the bottom plates 17 and 18 and having the two prismatic chambers 23 and 24 is fixed. The upper and lower rows of the mounting plate 25 form a pair, and holding claws 26 are fitted and fixed in a pair of I-shaped slits 19 cut out at the upper and lower positions of the baffle plate 10. In addition, the holding claws 26 are provided in a row along the attachment plate 25 so as to protrude by the number of baffle plates to be attached.

取付け板２５の保持部２７は、三角状の突起部２８を中心としてその左右に逆Ｕ字状の保持爪２６が突設されて１組をなしており、該逆Ｕ字状の保持爪２６はその外側となる角部２６ａをテーパー状に形成している。これにより、スリット１９が嵌入する際に保持爪２６の先端が先細り状となるため差込が容易で、しかもテーパー状の角部２６ａがスリットの挿入を案内し、角柱状に折込まれた２つの部屋２３、２４を備えたバッフル板１０を外側にやや開くようにして取付け板２５に押し込むことが出来る。中央に位置する三角形状の突起部２８はバッフル板１０を保持爪２６に挿入するときにガイドとなるもので、角柱状の２つの部屋２３、２４に折り込まれた内板２０、２１を三角形の稜線に沿って左右に振り分け、内板２０、２１の長辺の端部２０ａ、２１ａ同士が折衝して取付け板２５にしっかり固定する作用をする（図６参照）。しかも、端部２０ａ、２１ａは直線状に折衝することでミストを含んだ気流の流路を閉塞することなく確保している。   The holding portion 27 of the mounting plate 25 has a pair of inverted U-shaped holding claws 26 projecting from the left and right sides of a triangular projection 28, and the inverted U-shaped holding claw 26. Is formed with a tapered corner 26a. As a result, when the slit 19 is inserted, the tip of the holding claw 26 is tapered so that the insertion is easy, and the tapered corner portion 26a guides the insertion of the slit, and the two folded into a prismatic shape are provided. The baffle plate 10 provided with the chambers 23 and 24 can be pushed into the mounting plate 25 so as to be slightly opened outward. The triangular protrusion 28 located at the center serves as a guide when the baffle plate 10 is inserted into the holding claw 26, and the inner plates 20, 21 folded into the two prismatic chambers 23, 24 are arranged in a triangular shape. It distributes to right and left along the ridgeline, and the end portions 20a, 21a of the long sides of the inner plates 20, 21 are negotiated with each other and firmly fixed to the mounting plate 25 (see FIG. 6). In addition, the end portions 20a and 21a are secured in a straight line without blocking the air flow path including the mist.

尚、図８では塗装ブース１の前面に取付けたバッフル板１０を一部取り外して取付け板２５への取付け構成がわかる図としており、説明の便宜上組み込まれたバッフル板１０の上下端部に延伸される不織布の図示は省略している。   In FIG. 8, a part of the baffle plate 10 attached to the front surface of the painting booth 1 is partially removed so that the attachment configuration to the attachment plate 25 can be understood. For convenience of explanation, the baffle plate 10 is extended to the upper and lower ends of the baffle plate 10. The illustration of the nonwoven fabric is omitted.

本発明のバッフル板の場合、塗装ブースに取付けるために取付けスペースよりバッフル板１０の長さを短めに形成することが好ましい。即ち、バッフル板同士の塗料ミストによる固着防止のため、平板１１の縦長さを短めの寸法に形成し、バッフル板として取付けたときに上下に若干の隙間を設けて取付けられる。この隙間を埋める手段として前記不織布２２の延伸された耳片２２ａが用いられる。上下のバッフル板１０間に不織布２２の耳片２２ａが介在し、バッフル板１０に付着しない塗料ミストを吸着すると共に、耳片２２ａに塗料が付着した場合にもバッフル板１０同士の固着を防止している。汚れたバッフル板の交換時には塗料が付着した不織布の耳片２２ａをカッターなどで切離することで交換に必要なバッフル板のみを取り外すことができるようにしている。   In the case of the baffle plate of the present invention, it is preferable to form the baffle plate 10 shorter than the installation space in order to attach it to the painting booth. That is, in order to prevent the baffle plates from sticking to each other due to paint mist, the vertical length of the flat plate 11 is formed in a short dimension, and when the baffle plates are attached as a baffle plate, they are attached with a slight gap therebetween. As a means for filling this gap, an elongated piece 22a of the nonwoven fabric 22 is used. The ear piece 22a of the nonwoven fabric 22 is interposed between the upper and lower baffle plates 10, and adsorbs the paint mist that does not adhere to the baffle plate 10, and also prevents the baffle plates 10 from sticking to each other even when the paint adheres to the ear piece 22a. ing. When the dirty baffle plate is replaced, the non-woven ear pieces 22a to which the paint is attached are separated by a cutter or the like so that only the baffle plate necessary for the replacement can be removed.

次に本発明の作用を説明する。
塗装ブース１の前面開口部にはバッフル板１０が所要数取付けられ、塗装作業にあって被塗装物に塗着されない噴霧塗料ミストは、排気扇５の吸引により大部分がバッフル板１０に付着して捕捉され、バッフル板１０にて捕捉されない塗料ミストは、バッフル板１０の通気窓１６を通して吸引され角柱状の２つの部屋２３、２４内を通過するときに通気室２３ａ、２４ａ内の壁面に付着して捕捉され、わずかな塗料ミストのみが背部のフィルタ３にて二次的に処理されて清浄化された空気のみが外部に排出される。 Next, the operation of the present invention will be described.
The required number of baffle plates 10 are attached to the front opening of the painting booth 1, and most of the spray paint mist that is not applied to the object to be coated during painting work adheres to the baffle plate 10 due to the suction of the exhaust fan 5. The paint mist which is captured by the baffle plate 10 and is not captured by the baffle plate 10 is sucked through the ventilation window 16 of the baffle plate 10 and adheres to the wall surfaces in the ventilation chambers 23a and 24a when passing through the two rectangular columnar chambers 23 and 24. Then, only a small amount of paint mist, which has been secondarily processed by the back filter 3 and cleaned, is discharged to the outside.

勿論、バッフル板１０は平板１１の表裏面に不織布２２を接着して構成されているので、角柱状に折り込まれた２つの部屋２３、２４の内部の壁面にも不織布２２が露呈し、塗料ミストの捕捉を促進させている。   Of course, since the baffle plate 10 is formed by adhering the nonwoven fabric 22 to the front and back surfaces of the flat plate 11, the nonwoven fabric 22 is also exposed on the inner walls of the two chambers 23 and 24 folded in a prismatic shape, and the paint mist Is helping to capture.

尚、本発明のバッフル板１０は既存の塗装ブースにも取付けが可能である。即ち、図１０に示す既存のバッフル板Ａの取付け構造をそのまま採用することができ、取付け板Ｂのコ字状に突出する爪金具Ｃに本発明のバッフル板１０のスリット１９を嵌め込むことで容易に取付けできる。即ち、図７にその取付け構成を示すように、バッフル板１０はコ字状の爪金具Ｃがスリット１９に嵌入することで２つの角柱状の部屋２３、２４が左右に振り分けられ、内板２０、２１同士がその長辺の端部２０ａ、２１ａで折衝して取付け板Ｂに固定される。従って、既存の塗装ブースの取付け板をそのまま使用できる利点がある。また、取付け板自体は交換可能であるため、既存の塗装ブースに本発明の取付け板を取り付けることでも対処可能となる。   The baffle plate 10 of the present invention can be attached to an existing painting booth. That is, the mounting structure of the existing baffle plate A shown in FIG. 10 can be adopted as it is, and the slit 19 of the baffle plate 10 of the present invention is fitted into the claw metal fitting C protruding in the U shape of the mounting plate B. Easy to install. That is, as shown in FIG. 7, the baffle plate 10 has a U-shaped claw fitting C inserted into the slit 19, so that the two prismatic chambers 23, 24 are distributed to the left and right, and the inner plate 20 , 21 are negotiated at their long side ends 20a, 21a and fixed to the mounting plate B. Therefore, there is an advantage that the existing painting booth mounting plate can be used as it is. Further, since the mounting plate itself can be exchanged, it can be dealt with by attaching the mounting plate of the present invention to an existing painting booth.
