Description

本発明は、車体にエアを吹き付けて洗浄後の水滴を除去する乾燥装置を備えた洗車機に関するものである。   The present invention relates to a car wash machine provided with a drying device that blows air onto a vehicle body to remove water droplets after washing.

この種の洗車機として、門型状に形成した本体フレームに車体の上面にエアを吹き付ける上面乾燥ノズルを備えたものが知られている。車体の水滴除去は、所定風速・風量のエアを車体表面に垂直に近い角度で作用させるのが効果的とされているため、従来では上面乾燥ノズルを車体の上面形状に合わせて昇降させるとともに、自動車の傾斜に合わせて送風方向を可変する方法が採られている。送風方向を可変する手段として、上面乾燥ノズル全体を揺動させるもの(特許文献1)や送風口先端を揺動させるもの(特許文献2)が提案されているが、いずれも次のような問題があった。   As this type of car wash machine, there is known a car body having a top surface drying nozzle for blowing air onto the top surface of a vehicle body on a main body frame formed in a gate shape. For removing water droplets on the vehicle body, it is effective to let air of a predetermined wind speed and air volume act at an angle close to the surface of the vehicle body, so conventionally, the upper surface drying nozzle is raised and lowered according to the upper surface shape of the vehicle body, A method of changing the blowing direction according to the inclination of the automobile is employed. As means for changing the blowing direction, there have been proposed one that swings the entire upper surface drying nozzle (Patent Document 1) and one that swings the tip of the air blowing port (Patent Document 2). was there.

すなわち、上面乾燥ノズル全体を揺動させるものでは、大掛かりな動力が必要となり、動力源の設置スペースやノズルの揺動エリアを確保するのが困難であるとともに、送風機とノズルとを繋ぐダクトホースに曲げ応力が加わり劣化しやすいという問題があった。また、送風口先端を揺動させるものでは、動力や可動エリアを小さくできるというメリットがあるものの、ダクトからの送風を吹き出し直前で偏向するようにしているため、管路抵抗が大きくなり圧力損失による送風ロスが極めて大きくなるとともに、騒音発生の要因となるという問題があった。
特開平5−116598号 特開昭61−75047号
In other words, the one that swings the entire top surface drying nozzle requires a large amount of power, and it is difficult to secure a power source installation space and a nozzle swing area, and a duct hose that connects the blower and the nozzle. There was a problem that bending stress was applied and it was easy to deteriorate. In addition, although swinging the tip of the air outlet has the advantage that the power and movable area can be reduced, the air flow from the duct is deflected just before the blowout, resulting in increased pipe resistance and pressure loss. There was a problem that the air loss was extremely large and noise was generated.
Japanese Patent Laid-Open No. 5-116598 JP 61-75047 A

そこで、本発明が解決しようとする課題は、ノズルからの送風を最適に自動車車体に作用させることができ、しかも大きな動力が不要で送風ロスが少ない風向調整機能を有する上面乾燥装置を備えた洗車機を提供することを目的とするものである。   Therefore, the problem to be solved by the present invention is to provide a car wash equipped with a top surface drying device that can cause the air blown from the nozzle to act optimally on the vehicle body, and does not require a large amount of power and has a low airflow loss adjustment function. The purpose is to provide a machine.

このような課題を解決するために本発明は、洗車処理装置を装備した本体フレームを自動車と相対移動させるのに伴い、洗車処理装置により自動車車体を洗車処理する洗車機であって、洗車処理装置として少なくとも送風方向を自動車前後方向に調整する手段を有する車体上面乾燥手段を備えた洗車機において、風向調整手段を、車体上面乾燥手段の送風口における風向調整側に備えコアンダ効果により送風口からの送風を偏向する送風偏向体と、該送風偏向体を偏向位置と収納位置とに変位する駆動体とで構成したものである。   In order to solve such a problem, the present invention is a car wash machine for washing a car body with a car wash processing apparatus as the main body frame equipped with the car wash treatment apparatus is moved relative to the automobile. In the car wash machine having the vehicle body upper surface drying means having at least a means for adjusting the air blowing direction in the longitudinal direction of the automobile, the wind direction adjusting means is provided on the air direction adjusting side in the air blowing port of the vehicle body upper surface drying means, and from the air outlet by the Coanda effect. It is constituted by a blower deflecting body that deflects the blown air and a drive body that displaces the blower deflecting body between a deflection position and a storage position.

本発明の洗車機によれば、風向調整手段を上面乾燥ノズルの送風口における調整側(送風したい側)に収納位置と調整位置とに変位する調整板と、この調整板を駆動する駆動体で構成したので、小さな動力で済みダクトホースを劣化させることもなくなる。また、コアンダ効果を利用して送風口から吹き出される風の向きを調整するようにしたので、送風ロスと騒音の発生を防ぎながら送風機からの風を効率よく車体の傾斜面に作用させることが可能になる。   According to the car wash machine of the present invention, the wind direction adjusting means is disposed on the adjustment side (side on which air is desired to be blown) on the air blowing port of the upper surface drying nozzle, the adjustment plate being displaced between the storage position and the adjustment position, and the driver that drives the adjustment plate. Since it is configured, it requires less power and does not deteriorate the duct hose. In addition, since the direction of the wind blown from the air outlet is adjusted using the Coanda effect, the wind from the blower can be efficiently applied to the inclined surface of the vehicle body while preventing the occurrence of air loss and noise. It becomes possible.

図3・4は上面ブロワノズル6の構成を示しており、図3は側面図、図4は側面断面図である。
上面ブロワノズル6は、側面視漏斗状をなしており、上面に接続筒12を形成し送風ブロワ(図示しない)と連通する可撓性のダクトホース13が接続され、下面にノズル幅にわたって送風口14を開口している。送風口14には、風向調整装置15が設けられ、ダクトホース13を通じて供給される風が必要に応じて風向調整装置15で偏向されながら高圧で吹き出される。
3 and 4 show the configuration of the upper blower nozzle 6, FIG. 3 is a side view, and FIG. 4 is a side sectional view.
The upper surface blower nozzle 6 has a funnel shape when viewed from the side. A flexible duct hose 13 that is connected to a blower blower (not shown) is formed on the upper surface and communicates with a blower blower (not shown). Is open. The air outlet 14 is provided with a wind direction adjusting device 15, and the wind supplied through the duct hose 13 is blown out at a high pressure while being deflected by the air direction adjusting device 15 as necessary.

風向調整装置15は、送風口14の前端部及び後端部において幅寸法に合わせて取り付けられる送風偏向板16a,16bと、各送風偏向板16a,16bを駆動するエアシリンダ17a,17bとから構成されている。送風偏向板16a,16bは、断面略半円形状をなし、円弧面18a,18bが送風口14の開口縁と連続するように配置され、回転軸19a,19bを中心に所定角度回転するように取り付けられている。エアシリンダ17a,17bは、ロッド側の先端を送風偏向板16a,16bの側面に連係し、シリンダ側の先端を上面ブロワノズル6の一側面に軸支して取り付けられている。エアシリンダ17a,17bを伸縮させることにより、送風偏向板16a,16が送風口14からの風を垂直下向きに吹き出す格納位置と、送風口14からの風を円弧面18a,18bに沿って前方下向きもしくは後方下向きに偏向して吹き出す偏向位置とに変位する。   The air direction adjusting device 15 includes air blowing deflectors 16a and 16b attached to the front end portion and rear end portion of the air blowing port 14 according to the width dimension, and air cylinders 17a and 17b that drive the air deflecting plates 16a and 16b. Has been. The air deflecting plates 16a and 16b have a substantially semicircular cross section, are arranged so that the circular arc surfaces 18a and 18b are continuous with the opening edge of the air blowing port 14, and rotate about a predetermined angle about the rotation shafts 19a and 19b. It is attached. The air cylinders 17 a and 17 b are attached such that the rod-side tips are linked to the side surfaces of the blower deflecting plates 16 a and 16 b and the cylinder-side tips are pivotally supported on one side of the upper blower nozzle 6. By retracting and extending the air cylinders 17a and 17b, the storage position where the air deflecting plates 16a and 16 blow the air from the air blowing port 14 vertically downward, and the air from the air blowing port 14 forward and downward along the circular arc surfaces 18a and 18b. Alternatively, it is displaced to a deflection position where it is deflected rearward and blown out.

送風偏向板を偏向位置にすると、気流のコアンダ効果によりノズル6の送風口14からの気流が偏向位置に変位させた側の送風偏向板の円弧面に沿って流れるようになる。これにより、図5に示すように、送風偏向板16aを格納位置にし送風偏向板16bを偏向位置にすると本体フレーム1に対して前方下向きの風向が得られ(図5a)、送風偏向板16aを偏向位置にし送風偏向板16bを格納位置にすると本体フレーム1に対して後方下向きの風向が得られることになる(図5b)。こうしたコアンダ効果を利用した送風方向の偏向により、ノズル6からの気流は圧力損失を受けず、そのままの風速・風量を保ったまま所定の風向に偏向することが可能になる。   When the air deflecting plate is set to the deflection position, the air current from the air blowing port 14 of the nozzle 6 flows along the arc surface of the air deflecting plate on the side displaced to the deflecting position by the Coanda effect of the air flow. Accordingly, as shown in FIG. 5, when the air deflecting plate 16a is set to the retracted position and the air deflecting plate 16b is set to the deflected position, a forward and downward air direction is obtained with respect to the main body frame 1 (FIG. 5a). When the air deflecting plate 16b is set to the retracted position at the deflecting position, a rearward and downward air direction is obtained with respect to the main body frame 1 (FIG. 5b). By such deflection of the blowing direction using the Coanda effect, the airflow from the nozzle 6 is not subjected to pressure loss, and can be deflected in a predetermined wind direction while maintaining the same wind speed and volume.

また、上面ブロワノズル6は、側面に支持軸20が取り付けられており、昇降装置21により上下方向に昇降自在とされる。昇降装置21は、図6に示すように、支持軸20の先端に設けた台車22を、本体フレーム1の内側部に立設した昇降レール23上に昇降させるための機構で、台車の上下に連結されるチェーン24と、このチェーンが懸回される上下スプロケット25U,25Lと、左右の上スプロケット25U・25U同士を連結する回転軸26と、この回転軸を正逆転する昇降モータ27とから構成されている。28U・28Lはそれぞれレール23の上下端近傍に備えたリミットスイッチで、台車22の昇降限界位置を検出する。29は回転軸26の一端に連結した昇降エンコーダで、回転軸26の回転方向を検出しながら単位角度回転毎にパルス信号を出力して上面ブロワノズル6の昇降位置を与えている。   The upper blower nozzle 6 has a support shaft 20 attached to the side surface, and can be moved up and down by an elevating device 21. As shown in FIG. 6, the elevating device 21 is a mechanism for elevating a carriage 22 provided at the tip of the support shaft 20 on an elevating rail 23 erected on the inner side of the main body frame 1. A chain 24 to be connected, upper and lower sprockets 25U and 25L around which the chain is suspended, a rotating shaft 26 for connecting the left and right upper sprockets 25U and 25U, and a lifting motor 27 for rotating the rotating shaft forward and backward. Has been. 28U and 28L are limit switches provided in the vicinity of the upper and lower ends of the rail 23, respectively, and detect the lift limit position of the carriage 22. An elevator encoder 29 connected to one end of the rotary shaft 26 outputs a pulse signal for each unit angle rotation while detecting the direction of rotation of the rotary shaft 26 to give the upper and lower blower nozzle 6 a lift position.

尚、図4において、30は上面ブロワノズル6の前面及び後面に取り付けられるカバーで、送風偏向板16a,16の露出を低減するために被覆するものである。31は送風口14の開口縁に取り付けられるシール部材で、送風口14と送風偏向板16a,16との隙間を塞ぎ、ディフューザ効果により隙間から周囲の空気が吸い込まれることを防止し、吸い込みにより発生する騒音をなくすものである。   In FIG. 4, reference numeral 30 denotes a cover attached to the front and rear surfaces of the upper blower nozzle 6, which covers the air deflecting plates 16 a and 16 to reduce exposure. 31 is a sealing member attached to the opening edge of the air blowing port 14, which closes the gap between the air blowing port 14 and the air blowing deflecting plates 16a, 16 and prevents the surrounding air from being sucked in through the gap due to the diffuser effect. To eliminate noise.

図7は実施例1の制御系を示すブロック図である。
33はマイクロコンピュータを備えた制御部で、操作ボックス11において洗車を受け付け、走行位置検出装置9、車形検出装置10をはじめとする各種センサからの信号に基づき、操作ボックス11で選択した洗車メニューに沿って本体フレーム1の走行,ブラシ装置3・4・4およびブロワノズル6・7・7の作動,散水ノズルからの放水,シャッター体8の昇降を駆動回路34を介して制御するものである。
FIG. 7 is a block diagram illustrating a control system according to the first embodiment.
A control unit 33 having a microcomputer receives a car wash in the operation box 11 and selects a car wash menu selected in the operation box 11 based on signals from various sensors including the travel position detection device 9 and the vehicle shape detection device 10. The movement of the main body frame 1, the operation of the brush devices 3, 4, 4 and the blower nozzles 6, 7, 7, the water discharge from the watering nozzle, and the elevation of the shutter body 8 are controlled via the drive circuit 34.

操作ボックス11では、本体フレーム1が前方へ1回往行するだけで洗浄と乾燥とを完了するスピード洗車(0.5往復洗車)と、本体フレーム1が1往復して洗浄動作した後に2回目の往行時に乾燥動作するノーマル洗車(1.5往復洗車)と、本体フレーム1が1往復して洗浄動作とワックス塗布を行い2回目の往行時に乾燥動作するワックス洗車(1.5往復洗車)が選択できる。尚、この他にもコーティング処理・水垢処理などの処理を盛り込んで本体フレーム1の走行を2.5往復または3.5往復させてより付加価値の高い洗車動作をさせることもできる。   In the operation box 11, a speed car wash (0.5 reciprocating car wash) that completes cleaning and drying only by the main body frame 1 traveling forward once, and a second time after the main body frame 1 performs a reciprocating cleaning operation. A normal car wash (1.5 reciprocating car wash) that dries when the car goes out, and a wax car wash (1.5 reciprocating car wash) that the body frame 1 reciprocates once and performs a washing operation and wax application, and a drying operation during the second go. ) Can be selected. In addition to this, it is possible to incorporate a treatment such as a coating treatment and a water scale treatment so that the traveling of the main body frame 1 is reciprocated 2.5 times or 3.5 times to perform a car wash operation with higher added value.

さて、このように構成する洗車機の洗車動作例について、以下に説明する。尚、図8では前記したスピード洗車の動作を例示している。
洗車利用者が操作ボックス11において洗車料金を投入し、希望する洗車メニューを選択した後、自動車を所定の洗車位置に乗り入れると、本体フレーム1が往行を開始する。往行に伴い、走行位置検出装置9で本体フレーム1の走行位置を検出しながら車形検出装置10で自動車の上面位置を抽出し、自動車の上面形状を認識していく。
Now, an example of a car wash operation of the car wash machine configured as described above will be described below. FIG. 8 illustrates the operation of the speed car wash described above.
After a car wash user enters a car wash fee in the operation box 11 and selects a desired car wash menu, the main body frame 1 starts going when the car is put into a predetermined car wash position. As the vehicle travels, the top position of the vehicle is extracted by the vehicle shape detection device 10 while the travel position detection device 9 detects the travel position of the main body frame 1 to recognize the top shape of the vehicle.

洗浄部Sでは、散水ノズルより洗浄水及び洗剤水を放出しながら、まず上面ブラシ3が自動車の上面形状に沿って駆動し車体上面のブラッシング洗浄を行う。続いて、側面ブラシ4・4が本体フレーム1中央に向けて閉じ、この閉じた状態から自動車の前端に作用させて車体前面のブラッシング洗浄を行った後、再び側面ブラシ4・4が開いて自動車側面のブラッシング洗浄を行う。このとき、シャッター体8は下限位置まで下降してから、自動車の上面位置に沿って昇降し、洗浄動作に伴う洗浄水の飛散が乾燥部Dを至らないように遮蔽する。   In the cleaning section S, first, the upper surface brush 3 is driven along the shape of the upper surface of the automobile to perform brushing cleaning of the upper surface of the vehicle body while discharging the cleaning water and the detergent water from the watering nozzle. Subsequently, the side brushes 4 and 4 are closed toward the center of the main body frame 1, and from the closed state, the front brushes are applied to the front end of the vehicle to perform brushing cleaning on the front surface of the vehicle body. Brush the side. At this time, after the shutter body 8 is lowered to the lower limit position, the shutter body 8 is moved up and down along the upper surface position of the automobile to shield the scattering of cleaning water accompanying the cleaning operation from reaching the drying section D.

本体フレーム1の走行に伴い、自動車の前端部が洗浄部Sから乾燥部Dに入り込むと、ブロワノズル6・7・7より送風を開始し、自動車前端部から順次乾燥処理が施される。洗浄部Sでは、引き続き自動車の上面及び側面に対して洗浄水放出を伴うブラッシング洗浄が行われ、本体フレーム1内で洗浄と乾燥が同時進行された状態になる。   When the front end of the vehicle enters the drying unit D from the cleaning unit S as the main body frame 1 travels, the blower nozzles 6, 7, and 7 start to blow air and sequentially perform drying from the front end of the vehicle. In the cleaning section S, the top and side surfaces of the automobile are continuously subjected to brushing cleaning with discharge of cleaning water, and the cleaning and drying are performed in the main body frame 1 at the same time.

乾燥部Dでは、上面ブロワノズル6が、自動車の上面形状に追従して昇降し、できるだけ車体に近づいた状態で自動車の上面に送風し、側面ブロワノズル7が、自動車車体の側面に送風し、洗浄後の車体に残留する水滴を吹き飛ばしていく。ここで、本発明の特徴的構成である上面ブロワノズル6による乾燥作用について説明する。   In the drying section D, the upper surface blower nozzle 6 moves up and down following the shape of the upper surface of the vehicle and blows air to the upper surface of the vehicle as close as possible to the vehicle body, and the side blower nozzle 7 blows air to the side surface of the vehicle body and after washing Water droplets remaining on the car body are blown away. Here, the drying action by the upper surface blower nozzle 6 which is a characteristic configuration of the present invention will be described.

上面ブロワノズル6は、車形データに基づいて昇降装置21を作動し、自動車の上面形状に沿うように昇降制御されるとともに、乾燥する自動車Aの部位に応じて風向調整装置15を作動し、車体の傾斜に適した送風方向に指向させて効率の良い送風が行われる。   The upper surface blower nozzle 6 operates the lifting device 21 based on the vehicle shape data, is controlled to move up and down along the upper surface shape of the automobile, and operates the wind direction adjusting device 15 according to the part of the automobile A to be dried. The air is directed in the air blowing direction suitable for the inclination of the air and efficient air blowing is performed.

乾燥する自動車Aが普通車の場合、図9に示すように、上面ブロワノズル6が、自動車前面Cf・フロントウィンドウfwを乾燥するとき、送風偏向板16bを偏向位置に回転移動させ、本体フレーム1の前方下向きに偏向させて送風する。また、上面ブロワノズル6が、ボンネットbo・ルーフrf・トランクtrを乾燥するとき、送風偏向板16a,16bを格納位置とし、垂直下向きに送風する。更に、上面ブロワノズル6が、リアウィンドウrw・自動車後面Cfを乾燥するとき、送風偏向板16aを偏向位置に回転移動させ、本体フレーム1の後方下向きに偏向させて送風する。これにより、自動車Aの部位に適した送風を作用させることができる。しかも送風偏向板16a,16bは、コアンダ効果を利用しているため、従来のように送風口を強制的に曲げて風向を偏向するものと比べて、送風ロスが少なく、騒音の発生も低減される。   When the automobile A to be dried is a normal car, as shown in FIG. 9, when the upper blower nozzle 6 dries the automobile front Cf and the front window fw, the air blowing deflector 16 b is rotated and moved to the deflection position. Air is deflected forward and downward. Further, when the upper surface blower nozzle 6 dries the bonnet bo, the roof rf, and the trunk tr, the blower deflecting plates 16a and 16b are set in the retracted positions and the air is blown vertically downward. Furthermore, when the upper surface blower nozzle 6 dries the rear window rw and the rear surface Cf of the automobile, the blower deflecting plate 16a is rotationally moved to the deflection position and deflected rearward and downward of the main body frame 1 to blow air. Thereby, the ventilation suitable for the site | part of the motor vehicle A can be made to act. In addition, since the air deflecting plates 16a and 16b use the Coanda effect, the air blowing loss is less and the generation of noise is reduced compared to the conventional case where the air blowing is forcedly bent to deflect the air direction. The

こうして、自動車が乾燥部Dを抜けると、シャッター体8を待機位置である本体フレーム上方に上昇させ、ブロワを停止して洗車終了となる。その後、自動車Aをそのまま前進させて洗車エリアから退場させるよう促し、自動車の退場が検出されると、本体フレーム1をレール後端の待機位置に戻して次の洗車に備えるものである。以上のように本体フレーム1の往行に伴いブラッシング洗浄と乾燥処理とを同時進行で行って、従来の門型洗車機で1往復して行っていた洗車を半分の1回の往行だけで完了しスピード洗車が実行されるのである。   Thus, when the automobile passes through the drying section D, the shutter body 8 is raised above the main body frame, which is the standby position, and the blower is stopped to complete the car wash. Thereafter, the vehicle A is urged to move forward and leave the car wash area, and when the vehicle exit is detected, the main body frame 1 is returned to the standby position at the rear end of the rail to prepare for the next car wash. As described above, the brushing cleaning and the drying process are performed at the same time as the main body frame 1 travels, and the car washing that has been performed one reciprocation by the conventional gate-type car wash machine is performed only in one half of the outward travel. Once completed, a speed car wash is performed.

尚、本発明は、上記実施例に限定されるものではなく、請求項の記載を逸脱しない範囲で種々の実施態様が考えられる。実施例では本体フレーム1の前寄りに洗浄部Sを形成し後寄りに乾燥部Dを形成してあるが、現在広く普及している門型洗車機のように前寄りに乾燥部を設け後寄りに洗浄部を設け、本体の往復走行により洗車動作を行うものに適用できることは勿論である。また、本体フレーム内に自動車を台車やコンベアで搬送するタイプの洗車機においても同様に適用できる。更に、実施例の洗浄部Sではブラッシング洗浄を行うが、ブラシを備えず高圧スプレーで洗浄をはかる方式のブラシレス洗車機にも適用可能であることは明らかである。また、洗浄部と乾燥部を物理的に分離し、それぞれ独立して機能する形態の洗車装置もしくは乾燥装置にも採用することができる。更に、車形検出も上記した光軸の透光/遮光によって上面レベルを認識し、この上面レベルを本体フレームと自動車の相対移動位置単位で取り込んで車形データを作成するものに限らず、CCD等の撮像素子で撮影し、画像処理を施して車体輪郭を抽出するものでもよく、その手法は限定されない。また、風向調整装置を送風口の前後に設けているが、いずれか一方にしても良い。この場合、登り傾斜面への送風を考慮し、乾燥方向へ先行する向きに偏向できる側に設けるのが望ましい。   In addition, this invention is not limited to the said Example, A various embodiment can be considered in the range which does not deviate from description of a claim. In the embodiment, the cleaning unit S is formed at the front of the main body frame 1 and the drying unit D is formed at the rear. However, after the drying unit is provided at the front as in the case of a widely used portal type car wash machine, Needless to say, the present invention can be applied to an apparatus in which a washing section is provided near the vehicle and a car washing operation is performed by reciprocating the main body. Further, the present invention can be similarly applied to a car wash machine of a type in which an automobile is conveyed in a main body frame by a carriage or a conveyor. Further, although the cleaning unit S of the embodiment performs brushing cleaning, it is apparent that the cleaning unit S can be applied to a brushless car washer that does not have a brush and performs cleaning with high-pressure spray. Further, the washing unit and the drying unit can be physically separated, and the washing unit and the drying unit can be employed independently. Further, the vehicle shape detection is not limited to the above-described method of recognizing the upper surface level by the light transmission / shielding of the optical axis and taking the upper surface level in units of relative movement positions of the main body frame and the vehicle to create vehicle shape data. An image pickup device such as the above may be used to extract the body contour by performing image processing, and the method is not limited. Moreover, although the wind direction adjusting device is provided before and behind the air outlet, any one of them may be provided. In this case, it is desirable to provide it on the side that can be deflected in the direction preceding the drying direction in consideration of the air blow to the climbing inclined surface.
