【発明の属する技術分野】
本発明は、アミノ変性シリコーンオイルを含む艶出し剤を希釈水に混合する混合部と、その混合部で混合した前記艶出し剤と希釈水との混合液体を噴射する艶出し剤噴射ノズルとを備えた、洗車機における艶出し剤散布装置に関するものである。
【0002】
【従来の技術】
従来、アミノ変性シリコーンオイルを成分とする艶出し剤を希釈水に混合する混合部と、その混合部で混合した前記艶出し剤と希釈水との混合液体を噴射する艶出し剤噴射ノズルとを備えた、洗車機における艶出し剤散布装置において、1個の混合部に、車両の車体上面に混合液体を噴射する2個の艶出し剤噴射ノズルと、車両の右車体側面に混合液体を噴射する1個の艶出し剤噴射ノズルと、車両の左車体側面に混合液体を噴射する1個の艶出し剤噴射ノズルとの計4個の艶出し剤噴射ノズルを配管で接続したものが知られている(例えば、特許文献1を参照。)。
【0003】
【特許文献1】
特開2001−294133号公報
【0004】
【発明が解決しようとする課題】
前記従来の艶出し剤散布装置では、混合部と艶出し剤噴射ノズルとを接続するための配管が比較的長いので、その長い配管内で艶出し剤と希釈水とが十分に混合され、車体面の艶出しが均一に行える。
【0005】
しかしながら、アミノ変性シリコーンオイルは、希釈水にリン酸イオン、硫酸イオン、ケイ酸イオンなどが含まれると、それらのイオンと反応して反応物が生成されて析出し、その析出した反応物が配管を詰まらせることがあり、その場合には、長い配管に詰まった反応物を除去するのに手間がかかる問題があった。
【0006】
そこで、個々の艶出し剤噴射ノズル毎に混合部を設けて、混合部と艶出し剤噴射ノズルを接続する配管を短くすることにより、反応物で配管が詰まっても、その詰まった反応物を容易に除去できるようにすることが考えられるが、この場合には、艶出し剤と希釈水とが十分に混合されず、車体面の艶出しが不均一になる問題がある。
【0007】
本発明は、上記問題に鑑みてなされたもので、車体面の艶出しを均一に行うことができ、その上、混合部と艶出し剤噴射ノズルとの間に詰まったものを容易に除去できるようにした、洗車機における艶出し剤散布装置を提供することを目的とする。
【0008】
【課題を解決するための手段】
前記目的を達成するために、請求項1記載の発明は、アミノ変性シリコーンオイルを含む艶出し剤を希釈水に混合する混合部と、その混合部で混合した前記艶出し剤と前記希釈水との混合液体を噴射する艶出し剤噴射ノズルとを備えた、洗車機における艶出し剤散布装置において、前記混合部と前記艶出し剤噴射ノズルとの間には、前記艶出し剤と前記希釈水との混合を促進する混合促進部と、その混合促進部の下流側に続く整流部とが配設され、前記混合促進部は、前記混合液体を螺旋状に流動させる螺旋状通路と、該螺旋状通路の下流側に連なり該螺旋状通路を通過した直後の前記混合液体に乱流を生じさせて、その乱流効果により該混合液体中の前記艶出し剤と前記希釈水との混合を促進する乱流発生通路との組を複数組、互いに直列に配列して構成され、前記整流部は、前記混合促進部を通過した前記混合液体の回転流を鎮めてから、その混合液体を前記艶出し剤噴射ノズルから噴射させるための整流板を有することを特徴とする。
【0009】
また請求項2記載の発明は、請求項1記載の発明の前記特徴に加えて、前記艶出し剤噴射ノズルを複数備え、その個々の艶出し剤噴射ノズル毎に前記混合部が設けられることを特徴とする。
【0010】
また請求項3記載の発明は、請求項1又は2記載の発明の前記特徴に加えて、前記混合部と前記艶出し剤噴射ノズルとの間の配管が、その配管内部を随時清掃し得るように分解可能であることを特徴とする。
【0011】
【発明の実施の形態】
本発明の実施の形態を、添付図面に例示した本発明の実施例に基づいて以下に具体的に説明する。
【0012】
添付図面において、図1〜図11は本発明の一実施例を示すものであって、図1は、洗車機の全体側面図、図2は、洗車機の清水噴射装置、洗剤噴射装置、艶出し剤散布装置の配管系を示す斜視図、図3は、洗車機の艶出し剤散布装置の概略正面図(図1の3矢視図)、図4は、前記艶出し剤散布装置の配管ブロック図、図5は洗車機の作用の説明図、図6は、洗車機の制御シーケンスを示す図、図7は、艶出し剤噴射ユニットの縦断面図(図3の7−7線拡大断面図)、図8は図7の8矢視図、図9は、艶出し剤噴射ユニット内部の通路形成部材を単体状態で示す側面図、図10は図9の10−10線断面図、図11は、逆止弁ユニットの縦断面図(図3の8−8線拡大断面図)である。
【0013】
先ず、図1において、洗車機Wは、図示しない車両を跨ぐ門型フレーム1を備え、この門型フレーム1は複数の走行輪2,3を有していて、前記車両の側方で地上に敷設される左右一対の走行レール4に沿って走行可能、即ち前記車両の前後方向に沿って矢符aで示す方向に走行可能である。尚、門型フレーム1には、走行輪2を走行駆動するための走行駆動手段mが設けられる。
【0014】
門型フレーム1には回転ブラシ装置B、乾燥装置D、清水噴射装置R、洗剤噴射装置C及び艶出し剤散布装置Mが設けられている。
【0015】
回転ブラシ装置Bは、上面回転ブラシ5及び一対の側面回転ブラシ6を備える。上面回転ブラシ5は、門型フレーム1に回動自在に支承された横軸8に、揺動腕9を介して揺動自在に支承される。揺動腕9には、その上部に原動機10が設けられており、その原動機10から揺動腕9内の伝動機構を介して上面回転ブラシ5が回転駆動される。また、横軸8には、スプロケット11が固定されており、横軸8の下方で門型フレーム1には中間軸12が回動自在に支承されており、この中間軸12には他のスプロケット13が固定される。両スプロケット11、13には無端状チェン14が懸回されており、このチェン14の途中に固着された取付金具15には、門型フレーム1に下端を支承されたエアシリンダ16のピストン棒17が連結される。従ってエアシリンダ16を縮小駆動すれば、上面回転ブラシ5を二点鎖線で示すように上方格納位置5Uに保持することができる。また、エアシリンダ16を不作動の状態にすると、上面回転ブラシ5は、横軸8を中心として門型フレーム1の前後に、実線で示す下限位置5Dと上方格納位置5Uとの間を自由に揺動することができる。
【0016】
一対の側面回転ブラシ6の回転軸18は保持筒19に保持されており、その保持筒19は軸線を鉛直にして移動枠20に固着される。移動枠20は、門型フレーム1に横架した案内レール21に摺動可能に係合されており、案内レール21の支軸22は門型フレーム1に回動自在に支承される。従って、案内レール21、移動枠20、保持筒19、回転軸18及び側面回転ブラシ6は、支軸22を支点として走行方向4に揺動可能である。移動枠20には、原動機23が支持されており、この原動機23の出力軸に固定されたスプロケット24と、回転軸18の端部に固定されたスプロケット25とには無端状チェン26が懸回され、原動機23によって側面回転ブラシ6が回転駆動される。
【0017】
乾燥装置Dは、門型フレーム1の両側で内方に向けて開口する一対の側面送風ノズル27と、上部が下方に向けて開口する上面送風ノズル28とが送風機29に接続されて成り、上面送風ノズル28は図示しない昇降作動手段により乾燥すべき車両の車高に対応して昇降作動される。
【0018】
図2を併せて参照すると明らかなように、清水を車体表面に噴射し得る清水噴射装置Rは、サイドブラシ6の後方において門型フレーム1に設けられた門型の清水噴射管31を備えている。この清水噴射管31は、門型フレーム1の内方に噴口を向けた複数のノズル30を有しており、その清水噴射管31の上部中央は、電磁弁S1を介装した給水管32によって給水源に接続され、この給水源は、図示例では清水を溜めた水槽Wpと、その水中に浸漬されて前記給水管32に水を圧送する水中ポンプよりなる給水ポンプPとで構成される。
【0019】
従って給水ポンプPを駆動後、電磁弁S1を開弁すれば、清水を清水噴射管31の複数のノズル30から噴射することができる。
【0020】
洗剤を車体表面に噴射し得る洗剤噴射装置Cは、上面回転ブラシ5と乾燥装置Dとの中間位置において門型フレーム1に設けられた門型の洗剤噴射管37を備えている。その洗剤噴射管37は、門型フレーム1の内方に噴口を向けた複数のノズル36を有しており、その洗剤噴射管37の上部中央と洗剤タンクT2とは、エゼクタE2と電磁弁S3を介装した洗剤供給管38で接続されるとともに、前記エゼクタE2と給水ポンプPとは、電磁弁S4を介装した給水管32′で接続されている。したがって、給水ポンプPを駆動後、電磁弁S3、S4を開弁すれば、清水がエゼクタE2に供給され、そのエゼクタE2に発生する負圧によって洗剤タンクT2内の洗剤を吸引し、前記清水と混合した洗剤を洗剤噴射管37の複数のノズル36から噴射することができる。
【0021】
また、上記洗剤噴射装置Cに隣接して門型フレーム1に配設された艶出し剤散布装置Mは、アミノ変性シリコーンオイルを含む艶出し剤を車体表面に噴射し得るものであって、それは、門型フレーム1の内方に噴口を向けた4個のノズル39(即ち車両の車体上面に混合液体を噴射する第1,第2艶出し剤噴射ノズル39,39、車両の右車体側面に混合液体を噴射する第3艶出し剤噴射ノズル39、車両の左車体側面に混合液体を噴射する第4艶出し剤噴射ノズル39)をそれぞれ有して門型フレーム1に支持される第1〜第4噴射ユニットU…を備えている。
【0022】
そしてその個々の噴射ユニットUにおいては、艶出し剤噴射ノズル39毎に、アミノ変性シリコーンオイルを含む艶出し剤を希釈水に混合する混合部Xが配設されており、その各混合部Xと、それに対応する各艶出し剤噴射ノズル39との間、即ち各混合部Xの近傍の配管内には、艶出し剤と希釈水との混合を促進する混合促進部Yと、その混合促進部Yの下流側に続く整流部Zとが配設される。第1〜第4噴射ユニットU…は基本的に同一の構成であり、次に図3,4,7〜11を併せて参照して、その噴射ユニットUを説明する。
【0023】
各噴射ユニットUは、中空の角筒状又は円筒状に形成されたユニット本体50と、このユニット本体50の基端に螺合されると共に門型フレーム1に固着された支持筒51とを備え、この支持筒51は,電磁弁S2を介装した希釈水供給管52で給水ポンプPに接続される。またこの希釈水供給管52の途中には、エア供給源Aに連なり電磁弁S5を介装したエア供給管41が、T継ぎ手Gを介して接続されている。前記ユニット本体50は、支持筒51が一端に螺合される基部筒50aと、その基部筒50aの他端に基端が螺合される先部筒50bとより構成され、その先部筒50bの先端には艶出し剤噴射ノズル39が着脱可能に固着(図示例では螺着)される。
【0024】
その艶出し剤噴射ノズル39は、その先端部に開口される噴口39aが、洗浄すべき車両の前後方向と直交する方向に細長い噴射パターンを形成すべく、同方向に細長いスリット状に形成されている。
【0025】
前記ユニット本体50の内部には、通路形成部材53が先部筒50bと基部筒50aとの間に挟持されるように収納されており、従って、その通路形成部材53は、先部筒50bを基部筒50aより分離することによりユニット本体50内より脱着可能である。而してその通路形成部材53により、ユニット本体50の内部は、その基端側、即ち上流側より前記混合部X、混合促進部Y及び整流部Zが順次直列に画成される。
【0026】
前記混合部Xは、ユニット本体50の軸線方向に沿って延び支持筒51内に直接連通する希釈水導入ポート部54と、その希釈水導入ポート部54と直交して直接連通する艶出し剤導入ポート部55とで構成される。艶出し剤導入ポート部55には、これに直接螺合されたエルボ管56及び逆止弁ユニット57を介して艶出し剤供給管58が接続される。前記逆止弁ユニット57は、艶出し剤供給管58から混合部X側への一方向にだけ艶出し剤の供給を許容するものであって、通常は弁体57aがその自重で閉弁位置に保持される。
【0027】
前記艶出し剤供給管58は、アミノ変性シリコーンオイルを含む艶出し剤を貯溜した艶出し剤タンクT3に接続されており、その途中には、艶出し剤タンクT3内の艶出し剤を吸引して噴射ユニットUの混合部Xに圧送可能なチューブポンプPtが介装される。
【0028】
前記通路形成部材53は、前記混合促進部Yを形成するための混合促進部形成体60と、前記整流部Zを形成するための整流板61とで構成される。その混合促進部形成体60は、通しボルト62の前後両端の所定位置に円柱状の第1及び第2案内部63,64をそれぞれ螺合固定して構成され、その各案内部63,64の外周面には、前記ユニット本体50の内周面との間に螺旋状通路63s,64sをそれぞれ画成するための各々3条のねじ状突起63a,64aが突設されている。第1案内部63に対応した第1螺旋状通路63sの上流端は、前記混合部Xに直接開口しており、またその下流端は、第1及び第2案内部63,64間に形成された第1乱流発生通路65に直接開口している。一方、第2案内部64に対応した第2螺旋状通路64sの上流端は、前記第1乱流発生通路65に直接開口しており、またその下流端は、第2案内部64と整流部Zとの間に形成された第2乱流発生通路66に直接開口している。
【0029】
前記整流板61は、前記混合促進部Y(図示例では第2乱流発生通路65)を通過した直後の混合液体の旋回渦流即ち回転流を鎮めるためのもので、図示例では噴射ノズル39の噴口39aの長手方向に沿う平板状に形成される。
【0030】
而して、給水ポンプPを駆動後、電磁弁S2,S5を開弁すれば、希釈水としての清水がT継ぎ手Gで、エア供給源Aから供給された高圧エアにより加速されて、各噴射ユニットUにおける混合部Xの希釈水導入ポート部54に供給される。一方、チューブポンプPtを駆動すると、これが艶出し剤タンクT3内の艶出し剤を吸引し、逆止弁ユニット57を経て、各噴射ユニットUにおける混合部Xの艶出し剤導入ポート部55に供給され、これにより、該混合部Xにおいて艶出し剤と希釈水とが合流、混合される。
【0031】
次いでその混合液体は、混合促進部Yにおける第1螺旋状通路63s内を旋回移動し、その間に艶出し剤と希釈水との混合が進み、更にその第1螺旋状通路63sを出た混合液体の旋回流が第1乱流発生通路65において乱流を生じさせ、その乱流効果により艶出し剤と希釈水との混合が促進される。次いでその混合液体は、第2螺旋状通路64s内を旋回移動し、その間に艶出し剤と希釈水との混合が進み、更にその第2螺旋状通路64sを出た混合液体の旋回流が第2乱流発生通路66において乱流を生じさせ、その乱流効果により艶出し剤と希釈水との混合が促進される。
【0032】
このような螺旋状通路63s,64sとその直下流の乱流発生通路65,66とを含む混合促進部Yにおいては、通路長さが短くても艶出し剤と希釈水との混合が促進されるので、混合部Xと噴射ノズル39との間の配管を短くしても、艶出し剤と希釈水とが十分に混合した混合液体が得られる。
【0033】
更にその混合促進部Yを通過した直後の混合液体の旋回渦流即ち回転流を、整流部Zにおいてその回転流の回転方向に立ち塞がる整流板61で効果的に鎮めるようにした上で、その混合液体を艶出し剤噴射ノズル39より噴射させるので、その噴射パターン内における混合液体の分散が均一となる。即ち、もし整流板61が無い場合には、上記回転流の影響で噴射パターンの長手方向両端の混合液体量が相対的に多くなり、中心部の混合液体量が少なくなる。従って、前記した混合促進部Yによる艶出し剤と希釈水との混合促進効果とも相侯って、車体面の艶出しが均一に行われるようになる。
【0034】
かくして、噴射ノズル39から噴射される、清水と艶出し剤とを混合した混合液体は、泡立つことなく車体表面に均一に散布される。
【0035】
門型フレーム1には、後述する図6のシーケンスに基づいて洗車機Wの回転ブラシ装置B、乾燥装置D、清水噴射装置R、洗剤噴射装置C、艶出し剤散布装置Mおよび前記走行駆動手段を制御する制御装置SGが、外部より随時に選択操作可能に設けられる。
【0036】
前記艶出し剤タンクT3に貯留される艶出し剤は、アミノ変性シリコーンオイルと水を非イオン系界面活性剤で乳化した水性乳化液で、カチオン系界面活性剤及びアニオン系界面活性剤は含んでいない。
【0037】
次に、前記実施例の洗車機Wを用いて図6で示すシーケンスで艶出し方法を行う一連の工程について説明する。この場合には、門型フレーム1が走行レール4上を3回往復移動する間に、走行レール4の間に停車した車両Vに対して、洗浄工程、リンス工程、艶出し剤第1散布工程、艶出し剤第2散布工程、艶出し剤第3散布工程及び仕上げリンス工程、乾燥工程が順次に行なわれる。
▲1▼ 洗浄工程(第1往行)
電磁弁S1を開弁して給水ポンプPから供給される清水を清水噴射装置Rのノズル30から噴射させるとともに、2個の電磁弁S3、S4を開弁して洗剤噴射装置Cのノズル36から洗剤を噴射させ、同時に、門型フレーム1を図5のA、Bにおいて実線で示す走行レール4の左端から右方向に第1往行させ、回転ブラシ装置Bを回転駆動して車両Vの車体表面をブラシング洗浄する。即ち、洗剤噴射装置Cのノズル36から洗剤が車体表面に噴射され、次にその車体表面が回転ブラシ装置Bの上面回転ブラシ5及び一対の側面回転ブラシ6でブラシングされ、次にその車体表面に清水噴射装置Rのノズル30から清水が噴射されて濯ぎが行われる。
【0038】
門型フレーム1が図5のA、Bにおいて二点鎖線で示す走行レール4の右端に達したら、門型フレーム1の走行を停止して洗浄工程を終わる。
▲2▼ リンス工程(第1復行)
洗浄工程が終わり、門型フレーム1が図5のA、Bにおいて二点鎖線で示す走行レール4の右端にある状態で、洗剤噴射装置Cの電磁弁S3を閉弁して洗剤の供給を停止し、洗剤噴射装置C及び清水噴射装置Rの両方から清水を噴射させながら、門型フレーム1を左方向に第1復行させ、回転ブラシ装置Bで車体表面をブラシングしてリンスする。即ち、清水噴射装置Rのノズル30から清水が車体表面に噴射されて濯ぎが行われ、次にその車体表面が回転ブラシ装置Bの上面回転ブラシ5及び一対の側面回転ブラシ6でブラシングされ、次にその車体表面に洗剤噴射装置Cのノズル36から清水が噴射されて濯ぎが行われる。
【0039】
門型フレーム1が、図5のA、Bにおいて実線で示す走行レール4の左端に達したら、門型フレーム1の走行を停止させると共に、上面回転ブラシ5及び一対の側面回転ブラシ6の回転を停止させ、上面回転ブラシ5を上限格納位置5Uに上昇させて保持し、一対の側面回転ブラシ6を外方の格納位置(図5のBに示す6a、6a位置)に開放させて保持し、電磁弁S1、S4を閉弁し、リンス工程を終わる。
▲3▼ 艶出し剤第1散布工程(第2往行)
リンス工程が終わり、門型フレーム1が、図5のA、Bにおいて実線で示す走行レール4の左端にある状態で、給水ポンプPに加えて、チューブポンプPtも駆動した上で、電磁弁S2、S5を開弁し、これにより、艶出し剤散布装置Mの各噴射ノズル39から艶出し剤を噴射させ、門型フレーム1を右方向に第2往行させて、艶出し剤を車体表面に散布する。門型フレーム1が図5のA、Bにおいて二点鎖線で示す走行レール4の右端に達したら、門型フレーム1の走行を停止して艶出し剤第1散布工程を終わる。
【0040】
尚、この艶出し剤第1散布工程では、回転ブラシ装置Bによるブラシングは行わない。
【0041】
またこの艶出し剤第1散布工程では、清水と艶出し剤とが混合された混合液は、該混合液に混合される高圧エアで加速されて噴射され、車体表面に対して効果的に艶出し剤を付着させることができる。
▲4▼ 艶出し剤第2散布工程(第2復行)
艶出し剤第1散布工程が終わり、門型フレーム1が図5のA、Bにおいて二点鎖線で示す走行レール4の右端にある状態より門型フレーム1を左方向に第2復行させて、第1散布工程と同様に艶出し剤を車体表面に散布する。門型フレーム1が図5のA、Bにおいて実線で示す走行レール4の左端に達したら、門型フレーム1の走行を停止して艶出し剤第2散布工程を終わる。
【0042】
尚、この艶出し剤第2散布工程でも、回転ブラシ装置Bによるブラシングは行わない。
【0043】
またこの艶出し剤第2散布工程でも、清水と艶出し剤とが混合された混合液は、該混合液に混合される高圧エアで加速されて噴射され、車体表面に対して効果的に艶出し剤を付着させることができる。
【0044】
また、艶出し剤第1散布工程で艶出し剤が散布され終わった車体表面が空気に所定時間(図示例では5秒以上、1時間以下の範囲で適宜設定)曝された後、その車体表面に艶出し剤が散布されるため、車体表面に対して、より効果的に艶出し剤を付着させることができる。
▲5▼ 艶出し剤第3散布工程及び仕上げリンス工程(第3往行)
艶出し剤第2散布工程が終わり、門型フレーム1が、図5のA、Bにおいて実線で示す走行レール4の左端にある状態で、電磁弁S1を開弁して清水噴射装置Rのノズル30から清水を噴射させ、門型フレーム1を右方向に第3往行させて、艶出し剤を車体表面に散布すると共に、その第3散布工程で艶出し剤を散布し終わった車体表面が空気に曝された後、その車体表面に清水を噴射して、余剰の艶出し剤を洗い落とす。門型フレーム1が図5のA、Bにおいて二点鎖線で示す走行レール4の右端に達したら、門型フレーム1の走行を停止し、各ポンプP,Ptの駆動を停止し、電磁弁S1、S2、S5を閉弁して艶出し剤第3散布工程及び仕上げリンス工程を終わる。
【0045】
尚、この艶出し剤第3散布工程及び仕上げリンス工程でも、回転ブラシ装置Bによるブラシングは行わない。
【0046】
またこの艶出し剤第3散布工程でも、艶出し剤第1散布工程と同様に、清水と艶出し剤とが混合された混合液は、高圧エアで加速されて噴射され、車体表面に対して効果的に艶出し剤を付着させることができる。
【0047】
また、艶出し剤第2散布工程で艶出し剤が散布され終わった車体表面が空気に所定時間(図示例では5秒以上、1時間以下の範囲で適宜設定)曝された後、その車体表面に艶出し剤が散布されるため、車体表面に対して、より効果的に艶出し剤を付着させることができる。
▲6▼ 乾燥工程(第3復行)
艶出し剤第3散布工程および仕上げリンス工程が終わり、門型フレーム1が図5のA、Bにおいて二点鎖線で示す走行レール4の右端にある状態で、乾燥装置Dを作動させ、門型フレーム1を左方向に第3復行させて、車体表面の乾燥を行う。
【0048】
ところで艶出し剤中に含まれるアミノ変性シリコーンオイルは、希釈水にリン酸イオン、硫酸イオン、ケイ酸イオンなどが含まれると、それらのイオンと反応して反応物が生成されて析出し、その析出した反応物が、混合部Xより下流側の配管、即ちユニット本体50の内部を詰まらせることがある。その場合には、各噴射ユニットUにおいて、そのユニット本体50の基部筒50aより先部筒50bを分離して、内部の通路形成部材53を取り出した状態で、該通路形成部材53やユニット本体50内部を清掃し、詰まりの原因となった前記反応物を除去する。しかる後、その逆の手順でユニット本体50を組み立てる。尚、この詰まり除去作業に当たり、必要に応じて、ユニット本体50を支持筒51より取り外したり或いはユニット本体50をエルボ管56より取り外すようにしてもよい。
【0049】
かくして、本実施例では、個々の艶出し剤噴射ノズル39毎に混合部Xを設けたことで、それら噴射ノズル39が互いに距離をおいて配設されているにも拘わらず各混合部Xと各艶出し剤噴射ノズル39との間を接続する配管を何れも短くすることができ、その上、その配管(噴射ユニット)自体を分解可能としているので、該配管が反応物で詰まっても、その詰まった反応物を容易且つ迅速に除去することが可能である。

また、以上の実施例において、艶出し剤を圧縮エアで加速して噴射することにより、艶出し剤を車体表面に容易に付着させることができる効果が得られ、更に艶出し剤が散布され終わった車体表面が空気に所定時間曝された後、その車体表面に艶出し剤が散布されることにより、艶出し剤を車体表面に一層容易に付着させることができる効果が得られることが確認されたが、それら効果が得られる理由は、アミノ変性シリコーンオイルは空気中の炭酸ガスに対して鋭敏に反応する性質があって、該シリコーンオイルに炭酸ガスを吹き込むことによりその粘性が増加(即ち増粘)してゲル状になり、更には空気中に放置することで空気中の炭酸ガスとの反応により表面に皮膜が形成される等の性質が関与しているためと考えられる。
【0051】
更に第1散布工程で艶出し剤が散布され終わった車体表面を空気に所定時間曝すことにより、車体表面のアミノ変性シリコーンオイルが空気中の炭酸ガスと反応して増粘し、車体表面への付着力が強くなる上、次に第2散布工程で散布される艶出し剤中のアミノ変性シリコーンオイルが車体表面に付着し易くなってその付着率も向上し、これによっても、少量の艶出し剤で車体表面に良好な撥水性と艶が得られるようになり、その上、第2散布工程で散布されたアミノ変性シリコーンオイルの下に、第1散布工程で散布されて空気に所定時間曝された、車体表面への付着力が強いアミノ変性シリコーンオイルが存するので、これによっても良好な撥水性及び艶が長期間に亘り維持可能となる、と推測される。

また前記実施例では、混合促進部Yが、第1及び第2螺旋状通路63s,64sと、その各螺旋状通路63s,64sの下流側にそれぞれ連なる第1及び第2乱流発生通路63a,64aとを備えるものを示したが、本発明では、混合促進部における螺旋状通路と乱流発生通路の組を3組以上直列に配列するようにしてもよい。

更にその混合促進部を通過した直後の混合液体の回転流を整流部の整流板で鎮めてから、その混合液体を艶出し剤噴射ノズルより噴射させるので、その噴射パターン内における混合液体の分散が均一になり(即ち整流部が無い場合には、上記回転流の影響で噴射パターン両端の混合液体量が多くなり、中心部の混合液体量が少なくなる)、従って、前記した混合促進部による艶出し剤と希釈水との混合促進効果とも相侯って、車体面の艶出しを均一に行うことが可能となる。

This fresh water injection pipe 31 has a plurality of nozzles 30 with the nozzle holes directed inward of the portal frame 1, and the upper center of the fresh water injection pipe 31 is provided by a water supply pipe 32 having an electromagnetic valve S 1 interposed therebetween. In the illustrated example, the water supply source is configured by a water tank Wp in which fresh water is stored and a water supply pump P including a submersible pump that is immersed in the water and pumps water into the water supply pipe 32.
[0019]
Therefore, if the solenoid valve S <b> 1 is opened after driving the water supply pump P, fresh water can be injected from the plurality of nozzles 30 of the fresh water injection pipe 31.
[0020]
The detergent spraying device C capable of spraying detergent onto the surface of the vehicle body includes a gate-shaped detergent spraying tube 37 provided on the gate-shaped frame 1 at an intermediate position between the upper surface rotating brush 5 and the drying device D. The detergent injection pipe 37 has a plurality of nozzles 36 with the nozzle holes directed inward of the portal frame 1.

Therefore, if the solenoid valves S3 and S4 are opened after the feed pump P is driven, fresh water is supplied to the ejector E2, and the detergent in the detergent tank T2 is sucked by the negative pressure generated in the ejector E2, and the fresh water and The mixed detergent can be sprayed from the plurality of nozzles 36 of the detergent spray tube 37.
[0021]
Further, the polishing agent spraying device M disposed in the portal frame 1 adjacent to the detergent spraying device C can spray a polishing agent containing amino-modified silicone oil onto the surface of the vehicle body, The four nozzles 39 (that is, the first and second polishing agent injection nozzles 39 and 39 for injecting the liquid mixture onto the upper surface of the vehicle body, and the side surface of the right vehicle body of the vehicle) The first to first supported by the portal frame 1 have a third polish agent spray nozzle 39 for spraying the mixed liquid and a fourth polish agent spray nozzle 39 for spraying the mixed liquid on the left side of the vehicle. 4th injection unit U ... is provided.
[0022]
In each of the injection units U, for each of the polishing agent injection nozzles 39, a mixing unit X for mixing a polishing agent containing amino-modified silicone oil with dilution water is disposed. In addition, between each of the corresponding polishing agent spray nozzles 39, that is, in a pipe in the vicinity of each mixing portion X, a mixing promoting portion Y that promotes the mixing of the polishing agent and the dilution water, and the mixing promoting portion. A rectifying unit Z is disposed downstream of Y. The first to fourth injection units U have basically the same configuration. Next, the injection units U will be described with reference to FIGS.
[0023]
Each injection unit U includes a unit main body 50 formed in a hollow rectangular tube shape or a cylindrical shape, and a support tube 51 screwed to the base end of the unit main body 50 and fixed to the portal frame 1. The support cylinder 51 is connected to the water supply pump P through a dilution water supply pipe 52 having an electromagnetic valve S2. In the middle of the dilution water supply pipe 52, an air supply pipe 41 connected to the air supply source A and having an electromagnetic valve S5 interposed therebetween is connected via a T joint G. The unit body 50 includes a base tube 50a in which the support tube 51 is screwed to one end, and a tip tube 50b in which the base end is screwed to the other end of the base tube 50a, and the tip tube 50b. A polishing agent spray nozzle 39 is detachably fixed (screwed in the illustrated example) to the tip of the nozzle.
[0024]
The glaze injection nozzle 39 is formed in a slit shape in the same direction so that an injection hole 39a opened at the tip of the polishing agent injection nozzle 39 forms an elongated injection pattern in a direction orthogonal to the front-rear direction of the vehicle to be cleaned. Yes.
[0025]
Inside the unit main body 50, a passage forming member 53 is accommodated so as to be sandwiched between the front tube 50b and the base tube 50a. Therefore, the passage forming member 53 includes the front tube 50b. It can be detached from the unit main body 50 by separating from the base tube 50a. Thus, by the passage forming member 53, the mixing unit X, the mixing promoting unit Y, and the rectifying unit Z are sequentially defined in series inside the unit main body 50 from the base end side, that is, the upstream side.
[0026]
The mixing part X extends along the axial direction of the unit body 50 and communicates directly with the dilution water introduction port part 54 into the support cylinder 51, and introduces a polishing agent that communicates directly with the dilution water introduction port part 54. Port part 55 is comprised. A polish agent supply pipe 58 is connected to the polish agent introduction port section 55 via an elbow pipe 56 and a check valve unit 57 which are screwed directly to the polish agent introduction port section 55. The check valve unit 57 allows the supply of the polishing agent only in one direction from the polishing agent supply pipe 58 to the mixing portion X side. Normally, the valve body 57a is closed by its own weight. Retained.
[0027]
The polishing agent supply pipe 58 is connected to a polishing agent tank T3 that stores a polishing agent containing amino-modified silicone oil. In the middle of the polishing agent supply pipe 58, the polishing agent in the polishing agent tank T3 is sucked. A tube pump Pt that can be pumped to the mixing part X of the injection unit U is interposed.
[0028]
The passage forming member 53 includes a mixing promoting portion forming body 60 for forming the mixing promoting portion Y and a rectifying plate 61 for forming the rectifying portion Z. The mixing promoting portion forming body 60 is configured by screwing and fixing cylindrical first and second guide portions 63 and 64 at predetermined positions on both front and rear ends of the through bolt 62. On the outer peripheral surface, three threaded protrusions 63a and 64a for projecting spiral passages 63s and 64s, respectively, project from the inner peripheral surface of the unit body 50. The upstream end of the first spiral passage 63s corresponding to the first guide part 63 is directly open to the mixing part X, and the downstream end is formed between the first and second guide parts 63 and 64. The first turbulent flow generation passage 65 is directly open. On the other hand, the upstream end of the second spiral passage 64s corresponding to the second guide portion 64 is directly open to the first turbulent flow generation passage 65, and the downstream end thereof is connected to the second guide portion 64 and the rectifying portion. Opening directly to the second turbulent flow generation passage 66 formed between Z and Z.
[0029]
The rectifying plate 61 is for suppressing the swirling vortex, that is, the rotating flow of the mixed liquid immediately after passing through the mixing promoting portion Y (second turbulent flow generation passage 65 in the illustrated example). It is formed in a flat plate shape along the longitudinal direction of the nozzle hole 39a.
[0030]
Thus, if the solenoid valves S2 and S5 are opened after the water supply pump P is driven, the fresh water as the dilution water is accelerated by the T joint G by the high pressure air supplied from the air supply source A, and each injection It is supplied to the dilution water introduction port part 54 of the mixing part X in the unit U. On the other hand, when the tube pump Pt is driven, it sucks the polishing agent in the polishing agent tank T3 and supplies it to the polishing agent introduction port 55 of the mixing section X in each injection unit U via the check valve unit 57. Thus, the polishing agent and the dilution water are merged and mixed in the mixing section X.
[0031]
Subsequently, the mixed liquid swirls in the first spiral passage 63s in the mixing promoting portion Y, during which mixing of the polishing agent and the dilution water proceeds, and further the mixed liquid that has exited the first spiral passage 63s. The swirling flow generates turbulent flow in the first turbulent flow generation passage 65, and the mixing of the polishing agent and the dilution water is promoted by the turbulent flow effect. Subsequently, the mixed liquid swirls in the second spiral passage 64s, during which the mixing of the polishing agent and the dilution water proceeds, and the swirling flow of the mixed liquid that has exited the second spiral passage 64s 2 A turbulent flow is generated in the turbulent flow generation passage 66, and the mixing of the polishing agent and the dilution water is promoted by the turbulent flow effect.
[0032]
In the mixing promoting portion Y including the spiral passages 63s and 64s and the turbulent flow generation passages 65 and 66 immediately downstream of the spiral passages 63s and 64s, the mixing of the polishing agent and the dilution water is promoted even if the passage length is short. Therefore, even if the piping between the mixing part X and the injection nozzle 39 is shortened, a mixed liquid in which the polishing agent and the dilution water are sufficiently mixed can be obtained.
[0033]
Further, the swirl vortex of the mixed liquid immediately after passing through the mixing promoting portion Y, that is, the rotating flow, is effectively suppressed by the rectifying plate 61 that blocks in the rotating direction of the rotating flow in the rectifying portion Z, and the mixing is performed. Since the liquid is ejected from the polishing agent ejection nozzle 39, the dispersion of the mixed liquid in the ejection pattern becomes uniform. That is, if the rectifying plate 61 is not provided, the amount of liquid mixture at both ends in the longitudinal direction of the ejection pattern is relatively increased due to the influence of the rotational flow, and the amount of liquid mixture at the center is decreased. Accordingly, in combination with the effect of promoting the mixing of the polishing agent and the dilution water by the mixing promoting portion Y, the surface of the vehicle body is uniformly polished.
[0034]
Thus, the mixed liquid, which is injected from the injection nozzle 39 and is a mixture of fresh water and a polish, is uniformly distributed on the surface of the vehicle body without foaming.
[0035]
The portal frame 1 includes a rotating brush device B, a drying device D, a fresh water jetting device R, a detergent jetting device C, a polishing agent spraying device M, and the travel driving means of the car wash machine W based on a sequence shown in FIG. A control device SG is provided so as to be selectable from the outside at any time.
[0036]
The polishing agent stored in the polishing agent tank T3 is an aqueous emulsion obtained by emulsifying amino-modified silicone oil and water with a nonionic surfactant, and includes a cationic surfactant and an anionic surfactant. Not in.
[0037]
Next, a series of steps for performing the glazing method in the sequence shown in FIG. 6 using the car wash machine W of the above embodiment will be described. In this case, while the portal frame 1 reciprocates three times on the traveling rail 4, a washing process, a rinsing process, and a first polishing agent spraying process are performed on the vehicle V stopped between the traveling rails 4. The polishing agent second spraying step, the polishing agent third spraying step, the finishing rinse step, and the drying step are sequentially performed.
(1) Cleaning process (first outbound)
The solenoid valve S1 is opened and fresh water supplied from the water supply pump P is injected from the nozzle 30 of the fresh water injection device R, and the two electromagnetic valves S3 and S4 are opened and the nozzle 36 of the detergent injection device C is opened. At the same time, the detergent is sprayed, and the portal frame 1 is first moved in the right direction from the left end of the traveling rail 4 indicated by the solid line in FIGS. Brush and clean the surface. That is, the detergent is sprayed from the nozzle 36 of the detergent spraying device C onto the surface of the vehicle body, and then the surface of the vehicle body is brushed by the upper surface rotating brush 5 and the pair of side surface rotating brushes 6 of the rotating brush device B. Rinsing is performed by ejecting fresh water from the nozzle 30 of the fresh water injection device R.
[0038]
When the portal frame 1 reaches the right end of the traveling rail 4 indicated by the two-dot chain line in FIGS. 5A and 5B, the traveling of the portal frame 1 is stopped and the cleaning process is ended.
(2) Rinsing process (first return)
When the cleaning process is completed and the portal frame 1 is at the right end of the traveling rail 4 indicated by a two-dot chain line in FIGS. 5A and 5B, the electromagnetic valve S3 of the detergent injection device C is closed to stop the supply of the detergent. The gate-type frame 1 is first returned to the left while spraying fresh water from both the detergent spray device C and the clean water spray device R, and the surface of the vehicle body is brushed and rinsed by the rotating brush device B. That is, clean water is sprayed from the nozzle 30 of the fresh water injection device R onto the vehicle body surface for rinsing, and then the vehicle body surface is brushed by the upper surface rotation brush 5 and the pair of side surface rotation brushes 6 of the rotation brush device B. Further, rinsing is performed by spraying fresh water from the nozzle 36 of the detergent spraying device C onto the surface of the vehicle body.
[0039]
When the portal frame 1 reaches the left end of the traveling rail 4 indicated by a solid line in FIGS. 5A and 5B, the portal frame 1 stops traveling and the upper surface rotating brush 5 and the pair of side surface rotating brushes 6 are rotated. The upper surface rotating brush 5 is raised and held at the upper limit storage position 5U, and the pair of side surface rotating brushes 6 are opened and held at the outer storage positions (positions 6a and 6a shown in FIG. 5B), The solenoid valves S1 and S4 are closed and the rinsing process is finished.
(3) Polishing agent first application process (second outbound)
After the rinsing process is finished and the portal frame 1 is at the left end of the traveling rail 4 shown by the solid line in FIGS. 5A and 5B, in addition to the water supply pump P, the tube pump Pt is driven, and then the electromagnetic valve S2 , S5 is opened, and thereby, the polishing agent is sprayed from each of the spray nozzles 39 of the polishing agent spraying apparatus M, and the portal frame 1 is moved in the second direction to the right, so that the polishing agent is applied to the surface of the vehicle body. To spray. When the portal frame 1 reaches the right end of the traveling rail 4 indicated by the two-dot chain line in FIGS. 5A and 5B, the traveling of the portal frame 1 is stopped and the first polishing agent spraying process is completed.
[0040]
In this polishing agent first spraying step, brushing by the rotating brush device B is not performed.
[0041]
In the first spraying step of the polish, the mixed liquid in which fresh water and the polish are mixed is accelerated and injected by the high-pressure air mixed with the mixed liquid, and effectively polishes the surface of the vehicle body. An extractant can be deposited.
(4) Polishing agent second spraying process (second return)
When the first spraying step of the polishing agent is finished, the gate-type frame 1 is secondly moved backward in the left direction from the state in which the gate-type frame 1 is at the right end of the traveling rail 4 indicated by a two-dot chain line in FIGS. In the same manner as in the first spraying step, the polishing agent is sprayed on the surface of the vehicle body. When the portal frame 1 reaches the left end of the traveling rail 4 indicated by the solid line in FIGS. 5A and 5B, the traveling of the portal frame 1 is stopped and the second polishing agent spraying process is completed.
[0042]
Note that brushing by the rotating brush device B is not performed even in the second polishing agent spraying step.
[0043]
Also in the second spraying step of the polishing agent, the mixed liquid in which fresh water and the polishing agent are mixed is accelerated and injected by the high-pressure air mixed in the mixed liquid, so that the surface of the vehicle body is effectively polished. An extractant can be deposited.
[0044]
Further, after the surface of the vehicle body on which the polishing agent has been applied in the first application step of the polishing agent is exposed to air for a predetermined time (in the illustrated example, appropriately set in the range of 5 seconds to 1 hour), the vehicle body surface Since the polishing agent is sprayed on the surface, the polishing agent can be more effectively adhered to the surface of the vehicle body.

The nozzle of the fresh water injection device R is opened by opening the solenoid valve S1 in a state in which the second spraying step of the polishing agent is finished and the portal frame 1 is at the left end of the traveling rail 4 shown by a solid line in FIGS. 30 is sprayed with fresh water, and the gate-type frame 1 is moved in the third direction to the right to spray the polishing agent on the surface of the vehicle body. After being exposed to the air, fresh water is sprayed onto the surface of the vehicle body to wash off the excess polish. When the portal frame 1 reaches the right end of the traveling rail 4 indicated by a two-dot chain line in FIGS. 5A and 5B, the traveling of the portal frame 1 is stopped, the driving of the pumps P and Pt is stopped, and the solenoid valve S1 , S2 and S5 are closed to finish the third polishing agent spraying step and the finishing rinse step.
[0045]
In addition, brushing by the rotating brush apparatus B is not performed in the third polishing agent spraying step and the finishing rinse step.
[0046]
Also in the third spraying step of the polishing agent, as in the first spraying step of the polishing agent, the mixed liquid in which fresh water and the polishing agent are mixed is accelerated by high-pressure air and sprayed to the surface of the vehicle body. It is possible to effectively attach the polish.
[0047]
Further, after the surface of the vehicle body on which the polishing agent has been applied in the second application step of the polishing agent is exposed to air for a predetermined time (in the illustrated example, appropriately set within a range of 5 seconds to 1 hour), the vehicle body surface Since the polishing agent is sprayed on the surface, the polishing agent can be more effectively adhered to the surface of the vehicle body.
(6) Drying process (third return)
With the polishing agent third spraying step and the finishing rinsing step completed, the drying apparatus D is operated in a state where the portal frame 1 is at the right end of the traveling rail 4 indicated by a two-dot chain line in FIGS. The frame 1 is moved backward in the third direction to dry the surface of the vehicle body.
[0048]
By the way, when amino acid-modified silicone oil contained in the polishing agent contains phosphate ions, sulfate ions, silicate ions, etc. in the diluted water, it reacts with these ions to produce reactants, which are precipitated. The deposited reaction product may clog the piping on the downstream side of the mixing portion X, that is, the inside of the unit main body 50. In that case, in each injection unit U, the front tube 50b is separated from the base tube 50a of the unit main body 50, and the passage forming member 53 and the unit main body 50 are removed. The inside is cleaned to remove the reactants that cause clogging. Thereafter, the unit body 50 is assembled in the reverse procedure. In this clogging removing operation, the unit main body 50 may be removed from the support tube 51 or the unit main body 50 may be removed from the elbow pipe 56 as necessary.
[0049]
Thus, in this embodiment, the mixing portions X are provided for each of the polishing agent spray nozzles 39, so that the mixing portions X and the spray nozzles 39 are arranged at a distance from each other. Each of the pipes connecting between the polishing agent injection nozzles 39 can be shortened, and the pipe (injection unit) itself can be disassembled, so that even if the pipes are clogged with reactants, The clogged reactant can be easily and quickly removed.
[0050]
Further, in the above embodiment, by accelerating and spraying the polishing agent with compressed air, the effect of allowing the polishing agent to be easily attached to the surface of the vehicle body is obtained, and further, the polishing agent has been sprayed. After the car body surface is exposed to the air for a predetermined time, it is confirmed that the effect of allowing the glaze agent to adhere to the car body surface can be obtained more easily by spraying the caramel surface onto the car body surface. However, the reason why these effects are obtained is that amino-modified silicone oil has a property of sensitively reacting with carbon dioxide in the air, and its viscosity increases (that is, increases) by blowing carbon dioxide into the silicone oil. This is presumably because properties such as formation of a film on the surface due to reaction with carbon dioxide gas in the air by being allowed to stand in the air, are formed into a gel.
[0051]
Further, by exposing the surface of the vehicle body on which the polishing agent has been dispersed in the first spraying process to air for a predetermined time, the amino-modified silicone oil on the surface of the vehicle body reacts with carbon dioxide in the air to increase the viscosity, In addition to strengthening the adhesion, the amino-modified silicone oil in the polishing agent sprayed in the second spraying process is more likely to adhere to the surface of the vehicle body, improving the adhesion rate, and this also reduces the amount of polishing. With this agent, good water repellency and gloss can be obtained on the car body surface. In addition, it is sprayed in the first spraying process under the amino-modified silicone oil sprayed in the second spraying process and exposed to the air for a predetermined time. Since the amino-modified silicone oil having strong adhesion to the vehicle body surface exists, it is presumed that good water repellency and gloss can be maintained over a long period of time.
[0052]
Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various small design changes can be made without departing from the present invention described in the claims. Is possible. For example, in the above-described embodiment, a mobile car wash machine in which the vehicle V is stationary and the portal frame 1 as a frame is moved back and forth with respect to the vehicle V is used. However, in the present invention, the frame is fixed. A stationary car wash machine that moves the vehicle relative to the frame may be used.
[0053]
In the embodiment, the mixing promoting portion Y includes the first and second spiral passages 63s and 64s and the first and second turbulent flow generation passages 63a and 63s connected to the downstream sides of the spiral passages 63s and 64s, respectively. In the present invention, three or more sets of spiral passages and turbulent flow generation passages in the mixing promoting portion may be arranged in series.
[0054]
【The invention's effect】
As described above, according to the first aspect of the present invention, Since the mixing promotion part that promotes the mixing of the polishing agent and the dilution water is provided between the mixing part and the polishing agent injection nozzle, The piping connecting between the mixing section and the polishing agent spray nozzle can be shortened. And therefore Even if the piping is clogged with the reactant, the clogged reactant can be easily removed.
Also In particular, the mixing promoting unit includes a set of a spiral passage for causing the mixed liquid to flow spirally, and a turbulent flow generation passage for generating turbulence in the mixed liquid immediately after passing through the spiral passage. Since multiple sets are arranged in series with each other, as described above, the mixing section and the polishing agent spray nozzle are connected. Even if piping is shortened The In the mixing promotion section, Each pair Mixing of polish and dilution water proceeds in a spiral passage, Each set of spiral passages following each set In the turbulent flow path , Since the mixing of the polishing agent and the dilution water can be promoted by the turbulent flow effect, the mixing of the polishing agent and the dilution water is promoted as a whole, and a mixed liquid in which both are sufficiently mixed is obtained.
Furthermore, since the mixed liquid is injected from the polishing agent injection nozzle after the rotational flow of the mixed liquid immediately after passing through the mixing promoting part is suppressed by the rectifying plate of the rectifying part, the dispersion of the mixed liquid in the injection pattern is prevented. If there is no rectifying unit (that is, the amount of liquid mixture at both ends of the ejection pattern increases due to the influence of the rotational flow, the amount of liquid mixture at the center decreases), and therefore the gloss by the mixing promoting unit described above. Combined with the effect of promoting the mixing of the extractant and the dilution water, it is possible to uniformly polish the vehicle body surface.
[0055]
In addition, according to the invention described in claim 2, in addition to the effect of the invention described in claim 1, since the mixing section is provided for each of the plurality of polishing agent injection nozzles, the polishing agent injection nozzles are mutually connected. Even when a plurality of the nozzles are arranged at a distance, the pipes connecting the respective injection nozzles and the mixing section can be made as short as possible. Therefore, even if the pipes are clogged with the reactants, the reactant removal operation is facilitated.
[0056]
Further, in particular, according to the invention described in claim 3, in addition to the effect of the invention described in claim 1 or 2, the pipe between the mixing portion and the polish agent spray nozzle can clean the inside of the pipe at any time. Therefore, the reactant removal operation when the reactant is clogged in the pipe is further facilitated.
