Description

本発明は、例えば給油所に設置され洗車に使用される洗車機に関し、特に、被洗浄車両の上面に沿って昇降移動しながら乾燥用空気を吹き付けるトップ送風ノズルを備えた洗車機に関する。   The present invention relates to a car wash machine installed in a gas station, for example, and used for car washing, and more particularly, to a car wash machine provided with a top blowing nozzle that blows drying air while moving up and down along the upper surface of a vehicle to be cleaned.

従来、洗車に使用される洗車機としては、給油所などに設置されて、被洗浄車両と洗車機本体を前後方向に相対移動させながら、被洗浄車両に貯液タンクに貯留された液剤や洗浄水を噴射して、また、ブラッシングして洗車を行う構成とされる門型洗車機が知られている。   Conventionally, as a car wash machine used for car washing, it is installed in a gas station, etc., and the liquid agent and washing stored in the liquid storage tank in the car to be washed are moved relative to each other in the front-rear direction. 2. Description of the Related Art A gate type car wash machine is known which is configured to inject water and to perform car washing by brushing.

従来の門型洗車機の洗浄工程においては、先ず、洗浄水を用いて汚れを落とし、次いでシャンプーなどの液剤を用いて洗浄し、さらに洗浄水を用いて水洗いする。この洗浄工程の後で、各送風ノズルから送風して乾燥する乾燥工程が行われる。また、必要に応じてワックスや撥水コートなどの液剤塗布工程を適宜組み合わせて洗車を行う。このように、洗車の際に用いる液剤としては、各種のシャンプーやワックスやコート類が用いられており、それぞれ専用の貯液タンクに貯留され、タンク内に挿入されたチューブを介して、洗車工程の処理に応じて噴射され消費される。また、複数の洗車モードから所望のモードを選択し、使用する液剤の種類を選択して所定の洗車モードに設定する操作パネルやリモートパネルを備えている。操作パネルは洗車機本体に配設しているが、リモートパネルは洗車機本体から離れた位置に設置して、このリモートパネルと操作パネルとを電気的に接続して、リモートパネルに設定された洗車モードにより、洗車機を駆動可能にしている。   In the cleaning process of a conventional gate-type car wash machine, first, dirt is removed using washing water, then washing is performed using a liquid agent such as shampoo, and further washing is performed using washing water. After this washing process, a drying process is performed in which air is blown from each blowing nozzle and dried. In addition, car washing is performed by appropriately combining liquid agent application processes such as wax and water repellent coating as necessary. In this way, various shampoos, waxes and coats are used as liquid agents used in car washing, and each car wash process is stored in a dedicated liquid storage tank and inserted into the tank. It is injected and consumed according to the process. In addition, an operation panel and a remote panel are provided for selecting a desired mode from a plurality of car wash modes, selecting a type of liquid agent to be used, and setting a predetermined car wash mode. The operation panel is installed in the car wash machine body, but the remote panel is installed at a position away from the car wash machine body, and the remote panel is electrically connected to the operation panel. The car wash machine can be driven by the car wash mode.

上記した洗車機においては、被洗浄車両の側面を洗浄するためのサイドブラシと上面を洗浄するためのトップブラシと、洗浄した後で乾燥するためのサイド送風ノズルとトップ送風ノズルを備えているものが知られている。また、サイドブラシやトップブラシを被洗浄車両に軽く当接させた状態で洗浄を行うために、例えば、左右一対のサイドブラシを左右方向に移動可能(開閉可能)に支持し、トップブラシを上下に昇降可能に支持して、それぞれのブラシと車体との反発バランスにより、ブラシ位置を車体表面から一定距離に保つようにしている。また、それぞれのブラシを回転駆動するモータの電流値を検知し、この電流値を所定範囲内に抑制するように開閉移動もしくは昇降移動制御することにより、被洗浄車両の形状に沿って洗浄することが行われている。   The above-described car wash machine includes a side brush for cleaning the side surface of the vehicle to be cleaned, a top brush for cleaning the upper surface, a side blowing nozzle and a top blowing nozzle for drying after washing. It has been known. Also, in order to perform cleaning with the side brush and top brush lightly in contact with the vehicle to be cleaned, for example, a pair of left and right side brushes are supported so that they can be moved left and right (openable and closable), and the top brush is moved up and down. The brush position is maintained at a certain distance from the surface of the vehicle body by the repulsive balance between the brush and the vehicle body. In addition, by detecting the current value of the motor that rotationally drives each brush, and controlling the opening / closing movement or raising / lowering movement so as to suppress this current value within a predetermined range, washing is performed along the shape of the vehicle to be cleaned. Has been done.

さらに、被洗浄車両の車体形状を検知する車体検知センサを配設して、検知された車体の上面や側面に各ブラシや各送風ノズルなどの洗車具を近接させることも行われている。特に、上下方向に昇降移動して洗車操作を行うトップブラシやトップ送風ノズルなどの昇降洗車具は、その自重により下向きに荷重が付加されるので、車体表面に近接はしても接触しない工夫がなされている。   Furthermore, a vehicle body detection sensor for detecting the vehicle body shape of the vehicle to be cleaned is disposed, and car wash tools such as brushes and air blowing nozzles are brought close to the detected upper and side surfaces of the vehicle body. In particular, ascending / descending car wash tools such as top brushes and top blowing nozzles that move up and down in the vertical direction are loaded downward due to their own weights, so they do not come into contact with the vehicle body surface even if they are close to each other. Has been made.

例えば、昇降移動する部材の下端部に車体や障害物を検知するためのセンサを設けて、下降移動の途中で当該センサが車体や障害物を検知すると、そこで移動を停止させてそれ以上は下降させないように制御することが行われている。   For example, a sensor for detecting a vehicle body or an obstacle is provided at the lower end of a member that moves up and down, and when the sensor detects the vehicle body or an obstacle during the downward movement, the movement is stopped and the vehicle is further lowered. Control is made so as not to let it go.

また、車体表面に接近して乾燥用空気を吹き付けるトップ送風ノズルの車体への異常接近を検知するために、ノズル本体の下方、前方および後方に位置する部分を有するリング状検知体を設け、このリング状検知体が車体と接触する際の変位を検知することにより、トップ送風ノズルの駆動を制御して、トップ送風ノズルが車体に接触することを防止することが行われている(例えば、特許文献1参照)。   Further, in order to detect an abnormal approach to the vehicle body of the top blowing nozzle that approaches the vehicle body surface and blows drying air, a ring-shaped detector having portions located below, in front and behind the nozzle body is provided. By detecting the displacement when the ring-shaped detector comes into contact with the vehicle body, the drive of the top blow nozzle is controlled to prevent the top blow nozzle from coming into contact with the vehicle body (for example, patents). Reference 1).

また、リング状検知体の中立維持を凹V状面と凸V状面とを当接させて図ると共に、棒状樹脂体にて支持し、樹脂体の弾性力に抗して変位させて、この変位を検知することによりトップ送風ノズルの駆動を制御する構成とした洗車機も既に提案されている(例えば、特許文献2参照)。   Further, the neutrality of the ring-shaped detection body is maintained by bringing the concave V-shaped surface and the convex V-shaped surface into contact with each other, supported by a rod-shaped resin body, and displaced against the elastic force of the resin body. A car wash machine configured to control the driving of the top blowing nozzle by detecting displacement has already been proposed (see, for example, Patent Document 2).

トップ送風ノズルは車体の上面に沿って乾燥用空気を吹き付けるので、車体表面が傾斜した部分では、吹出し口を車体表面に対向させるようにノズル本体を傾斜させることが好ましい。従って、ノズル本体の周囲を周回するようにして配設されるリング状検知体は、この傾斜駆動の際に変位せず誤動作しないことが望まれる。   Since the top air blowing nozzle blows drying air along the upper surface of the vehicle body, it is preferable that the nozzle body is inclined so that the air outlet is opposed to the vehicle body surface in a portion where the vehicle body surface is inclined. Accordingly, it is desirable that the ring-shaped detector disposed so as to circulate around the nozzle body is not displaced and does not malfunction during the tilt driving.

しかしながら、特許文献1に記載の発明では、2本の引っ張りバネを用いてリング状検知体の中立維持を図っているので、ノズル本体を傾ける操作の際に、センサと検知板がずれてしまい誤検知し易くなっていた。   However, since the invention described in Patent Document 1 uses two tension springs to maintain the neutrality of the ring-shaped detection body, the sensor and the detection plate are misaligned when the nozzle body is tilted. It was easy to detect.

特許文献2に記載の発明では、リング状検知体の中立維持を簡単且つ安価に構成するために、凹V状面を有する受け部材と凸V状面を有する遊動部材とを嵌め合わせると共に、バネ部材は用いずに弾性を有する棒状樹脂体を用いて遊動部材を支持している。   In the invention described in Patent Document 2, in order to easily and inexpensively maintain the neutrality of the ring-shaped detector, the receiving member having the concave V-shaped surface and the floating member having the convex V-shaped surface are fitted together, and the spring The floating member is supported by using a rod-shaped resin body having elasticity without using a member.

また、棒状樹脂体の両端部を筒状保持体にて支持しリング状検知体を遊動部材に取り付けているので、ノズル本体を傾けても、リング状検知体が容易に変位せずセンサと検知板がずれ難くなっていることは明らかであるが、より簡単な構成により、リング状検知体が誤動作しないことが望まれる。   In addition, since both ends of the rod-shaped resin body are supported by the cylindrical holding body and the ring-shaped detection body is attached to the floating member, the ring-shaped detection body is not easily displaced even when the nozzle body is tilted. It is clear that the plate is not easily displaced, but it is desirable that the ring-shaped detector does not malfunction due to a simpler configuration.

本発明は、上記問題点に鑑み、被洗浄車両の表面に沿って移動しながら乾燥用空気を吹き付けるトップ送風ノズルにノズル本体の周囲を巻回するように配設されるリング状検知体を設けた洗車機において、トップ送風ノズルが振動または傾斜動作しても容易に変位せずに誤検知しないリング状検知体を備えた洗車機を提供することを目的とする。   In view of the above problems, the present invention provides a ring-shaped detector disposed around a nozzle body around a top blowing nozzle that blows drying air while moving along the surface of the vehicle to be cleaned. Another object of the present invention is to provide a car wash machine provided with a ring-shaped detector that is not easily displaced even when the top blowing nozzle vibrates or tilts and does not detect erroneously.

The vehicle sensor 8 includes a photoelectric sensor, an ultrasonic sensor, and the like, and detects the vehicle to be cleaned CA that enters the car wash machine body 1. Moreover, the structure which provides the external shape detection part 9 which detects the external shape of the to-be-cleaned vehicle CA in the entrance part of the car wash machine main body 1 may be sufficient.

洗車機本体1の一方の側方の前面には操作パネル7が配される。操作パネル7はリモートパネル7Aと同様の操作ボタンを備え、被洗浄車両CAから降車したユーザ等の操作により洗車の受け付けや洗車条件の設定を行う。   An operation panel 7 is disposed on the front surface on one side of the car wash body 1. The operation panel 7 has the same operation buttons as the remote panel 7A, and accepts a car wash and sets car wash conditions by the operation of a user who gets off the vehicle to be cleaned CA.

洗車条件の設定としてはシャンプー、ワックス掛け、撥水コート等を水洗いに追加するボタンが操作パネル7及びリモートパネル7Aに設けられる。また、高級なシャンプー、高級なワックス(例えば、艶出しコーティング)、高級な撥水コート、特殊なコート等を行うボタンも設けられている。さらに、フロントガード有り、フェンダーポール有り、ドアミラー有り、リヤワイパー有り、該当装備品無し等の装備品設定ボタンが設けられている。   As setting of the car wash conditions, buttons for adding shampoo, waxing, water repellent coat, etc. to the water wash are provided on the operation panel 7 and the remote panel 7A. In addition, buttons for performing high-grade shampoo, high-grade wax (for example, glazing coating), high-grade water repellent coating, special coating, and the like are also provided. In addition, equipment setting buttons such as front guard, fender pole, door mirror, rear wiper, and no applicable equipment are provided.

また、サイドブラシ5は、揺動ブラシホルダを介して揺動可能に吊り下げられ、左右方向に摺動可能な構成とされており、当初は被洗浄車両CAから離れた開位置にあるサイドブラシ5を閉位置方向(車両の側面に近接する方向)に移動し、被洗浄車両CAの側面に当接させ、さらに移動させると徐々に傾いていく(所定角度揺動する)。そのために、所定角度揺動した位置で閉方向への移動を停止し、この位置から所定の戻し距離、開方向に移動した位置で回転させて洗浄を行う。   The side brush 5 is suspended so as to be swingable via a swing brush holder, and is configured to be slidable in the left-right direction. The side brush 5 is initially in an open position away from the vehicle CA to be cleaned. 5 is moved in the closed position direction (direction approaching the side surface of the vehicle), brought into contact with the side surface of the vehicle CA to be cleaned, and gradually tilted (oscillates by a predetermined angle) when moved further. For this purpose, the movement in the closing direction is stopped at a position that has been swung by a predetermined angle, and cleaning is performed by rotating at a position that has moved in the opening direction by a predetermined return distance from this position.

左右一対のサイドブラシ5は、それぞれが個別の駆動モータを有し、それぞれ個別に駆動制御される。そのために、左右のそれぞれのサイドブラシ5を被洗浄車両CAの側面に当接して所定角度傾斜させた後、所定距離戻してその傾斜を小さくした位置でそれぞれのサイドブラシ5を回転操作して、側面への押し付け強さを緩和して車両の両側面の洗車を行うことができる。また、この際にこの洗浄する傾斜した姿勢を維持するために、ウエイトの付勢力を利用して押し付け強さを得る場合もある。   Each of the pair of left and right side brushes 5 has an individual drive motor and is individually driven and controlled. For this purpose, the left and right side brushes 5 are brought into contact with the side surfaces of the vehicle to be cleaned CA and tilted by a predetermined angle, and then each side brush 5 is rotated at a position where the tilt is reduced by returning a predetermined distance, The car can be washed on both sides of the vehicle by reducing the pressing force on the side. At this time, in order to maintain the inclined posture to be washed, the pressing force may be obtained by using the biasing force of the weight.

トップブラシ4も、個別の駆動モータを有しており、ブラシ体を被洗浄車両CAの上面に当接させた状態で、回転駆動して洗浄する。また、洗浄後に乾燥用空気を吹き付ける各送風ノズルもそれぞれ車体表面に接近可能に構成される。そのために、トップ送風ノズル21は上下方向に昇降可能な構成とされ、前述した車両センサ8や外形検出部9などにより検知された車両形状に応じて、また、トップ送風ノズル21に設ける車体検知センサの検知信号に応じて昇降駆動される。   The top brush 4 also has an individual drive motor and is driven to rotate and cleaned in a state where the brush body is in contact with the upper surface of the vehicle CA to be cleaned. In addition, each blowing nozzle that blows drying air after cleaning is also configured to be accessible to the vehicle body surface. For this purpose, the top blowing nozzle 21 is configured to be vertically movable, and a vehicle body detection sensor provided on the top blowing nozzle 21 according to the vehicle shape detected by the vehicle sensor 8 or the outer shape detection unit 9 described above. It is driven up and down according to the detection signal.

外形検出部9は、例えば、洗車機本体1の一方の側部の上下方向に配設する投光器9aと、他方の側部の上下方向に配設する受光器9bを有する透過式光電センサからなるエリアセンサを用いており、投光器9aと受光器9bの間に位置する被洗浄車両CAの車形(外形)を検出する。   The outer shape detection unit 9 includes, for example, a transmissive photoelectric sensor having a projector 9a disposed in the vertical direction on one side of the car wash machine body 1 and a light receiver 9b disposed in the vertical direction on the other side. An area sensor is used to detect the vehicle shape (outer shape) of the vehicle CA to be cleaned located between the projector 9a and the light receiver 9b.

トップ送風ノズル21は、被洗浄車両CAの上面に沿って移動しながら乾燥用空気を吹き付けるので、平坦な天井部に加えて、傾斜したフロントガラス面やリアガラス面などにも容易に対応して昇降移動および傾斜移動しながら安全に、また確実に操作することが求められる。そのために、本実施形態においては、トップ送風ノズル21を昇降可能に、また傾斜可能に構成し、さらに、トップ送風ノズル21が車体表面に接近し過ぎた時に、先に車体表面に安全に接触して異常に接近したことを検知可能なリング状検知体30を設けた構成としている。   Since the top blowing nozzle 21 blows drying air while moving along the upper surface of the vehicle CA to be cleaned, in addition to the flat ceiling, the top blowing nozzle 21 can easily move up and down in response to inclined front glass surfaces and rear glass surfaces. It is required to operate safely and reliably while moving and tilting. Therefore, in the present embodiment, the top blowing nozzle 21 is configured to be movable up and down and tiltable, and when the top blowing nozzle 21 comes too close to the vehicle body surface, the top fan nozzle 21 comes into safe contact with the vehicle body surface first. Thus, a ring-shaped detector 30 is provided that can detect an abnormal approach.

そこで、本実施形態に係るリング状検知体30の構成について図3および図4Aを用いて詳細に説明する。トップ送風ノズル21を昇降可能、傾斜可能に支持する構成は従来公知であるのでここでは詳述しない。   Therefore, the configuration of the ring-shaped detector 30 according to the present embodiment will be described in detail with reference to FIGS. 3 and 4A. Since the structure which supports the top ventilation nozzle 21 so that raising / lowering and inclination is possible is conventionally well-known, it does not elaborate here.

図3に示すように、本実施形態に係るトップ送風ノズル21は、乾燥用空気を吹き出す吹出部21bを備えたノズル本体21aの天板部にリング状検知体30を装着している。リング状検知体30は支持部SDを構成するベース部材33を備えており、このベース部材33を介してノズル本体21aの天板部に固定する。   As shown in FIG. 3, the top blowing nozzle 21 according to the present embodiment has a ring-shaped detector 30 attached to the top plate portion of a nozzle body 21 a provided with a blowing portion 21 b that blows drying air. The ring-shaped detection body 30 includes a base member 33 that constitutes a support portion SD, and is fixed to the top plate portion of the nozzle body 21a via the base member 33.

リング状検知体30は、ノズル本体21aの下方、前方および後方に位置するリング状部31と、該リング状部31をノズル本体21aに対する上方向と回動する方向に移動可能に支持する支持部SDと、リング状部31の変位を検知する検知手段S1(図4B参照)と、を有する。また、リング状部31はリング固定部材32に固定されており、この固定部材32にピン部材36を装着している。   The ring-shaped detector 30 includes a ring-shaped portion 31 positioned below, in front and behind the nozzle body 21a, and a support portion that supports the ring-shaped portion 31 so as to be movable in an upward direction and a rotating direction with respect to the nozzle body 21a. It has SD and detection means S1 (refer FIG. 4B) which detects the displacement of the ring-shaped part 31. FIG. The ring-shaped portion 31 is fixed to a ring fixing member 32, and a pin member 36 is attached to the fixing member 32.

支持部SDは、ノズル本体21aの上面に装着するベース部材33と、このベース部材33と所定間隔離間して装着される対向面体34とを有し、ベース部材33と対向面体34との間にリング固定部材32を摺動可能に嵌め込み、ベース部材33にリング固定部材32の前方部と後方部の二か所を下方から支持するリング支持部38A、38Bを設けている。この構成であれば、ベース部材33と対向面体34との間にリング固定部材32を装着し、リング固定部材32を2点支持するので、トップ送風ノズル21が傾斜動作しても、リング状検知体30を安定して支持することが可能になる。   The support portion SD includes a base member 33 that is mounted on the upper surface of the nozzle body 21a, and a facing surface body 34 that is mounted at a predetermined distance from the base member 33, and is between the base member 33 and the facing surface body 34. The ring fixing member 32 is slidably fitted, and the base member 33 is provided with ring support portions 38A and 38B for supporting the front portion and the rear portion of the ring fixing member 32 from below. With this configuration, the ring fixing member 32 is mounted between the base member 33 and the opposed surface body 34 and the ring fixing member 32 is supported at two points. Therefore, even if the top blowing nozzle 21 is tilted, the ring-shaped detection is performed. It becomes possible to support the body 30 stably.

また、図4A、図4Bに示すように、リング固定部材32にピン部材36を設け、ピン部材36を下方に付勢するように、ベース部材33に設ける付勢手段取付部40とリング固定部材32に設ける付勢手段取付部31cとに懸架する付勢手段37を設置している。   4A and 4B, a pin member 36 is provided on the ring fixing member 32, and a biasing means mounting portion 40 and a ring fixing member provided on the base member 33 so as to bias the pin member 36 downward. The urging means 37 that is suspended from the urging means attaching portion 31 c provided at 32 is provided.

ピン部材36は、対向面体34とベース部材33の少なくとも一方または両方に設ける三角溝状ガイド部35(35A、35B)に摺動自在に支持される。この三角溝状ガイド部35(35A、35B)は、底部ガイド面35aと該底部ガイド面35aから前後の上方に傾斜して延設される傾斜ガイド面35bとを備えたテーパ形状が好ましく、例えば図示するように、下方に頂部を有する逆三角形とされる。ただし、底部ガイド面35aと傾斜ガイド面35bとを備えた形状であればその他の形状でよく、下方に頂部を有するテーパ状のガイド形状であればよい。
The pin member 36 is slidably supported by a triangular groove-shaped guide portion 35 (35A, 35B) provided on at least one or both of the opposing face member 34 and the base member 33. The triangular groove-shaped guide portion 35 (35A, 35B) preferably has a tapered shape including a bottom guide surface 35a and an inclined guide surface 35b extending obliquely upward and backward from the bottom guide surface 35a. As shown in the figure, it is an inverted triangle having a top at the bottom. However, other shapes may be used as long as the shape includes the bottom guide surface 35a and the inclined guide surface 35b, and a tapered guide shape having a top portion below may be used.

リング状部31は1本の周回リングであってもよいが、図示するように一部を省いて、その両端をリング固定部材32に固定する構成であってもよい。例えば、リング状部31の上部中央部の所定間隔離間した2点を固定する(ネジ固定する)前方取付部31aと後方取付部31bを設け、前方取付部31aと後方取付部31bとの中間に付勢手段取付部31cを設けるとよい。   The ring-shaped portion 31 may be a single rotating ring, but may be configured such that a part thereof is omitted and both ends thereof are fixed to the ring fixing member 32 as illustrated. For example, a front mounting portion 31a and a rear mounting portion 31b for fixing (fixing with screws) two points spaced apart from each other at a central portion of the upper portion of the ring-shaped portion 31 are provided, and between the front mounting portion 31a and the rear mounting portion 31b. A biasing means attachment portion 31c may be provided.

また、この付勢手段取付部31cの上方にピン部材36を装着していることが好ましい。この構成であれば、リング状部31の上部を2点固定すると共に、この2点の中間部分の上方にピン部材36を装着して下方に付勢することによりリング状部31の初期位置(中立位置)を規定しているので、1個の付勢手段37によりリング状検知体30の中立位置を安定して維持可能になる。   Moreover, it is preferable that the pin member 36 is mounted above the urging means attachment portion 31c. With this configuration, the upper portion of the ring-shaped portion 31 is fixed at two points, and the pin member 36 is mounted above the middle portion of the two points and biased downward, whereby the initial position of the ring-shaped portion 31 ( Since the neutral position is defined, the neutral position of the ring-shaped detector 30 can be stably maintained by the single biasing means 37.

付勢手段37は、例えばスプリングであり、その一端側をベース部材33に設ける付勢手段取付部40に懸架し、他端側を付勢手段取付部31cに懸架するコイルスプリングから成ることが好ましい。この構成であれば、1本のコイルスプリングによりリング状検知体30の初期位置および変位姿勢を良好に保持することが可能になる。   The biasing means 37 is, for example, a spring, and preferably comprises a coil spring having one end side suspended from a biasing means mounting portion 40 provided on the base member 33 and the other end side suspended from the biasing means mounting portion 31c. . If it is this structure, it will become possible to hold | maintain the initial position and displacement attitude | position of the ring-shaped detection body 30 favorably with one coil spring.

上記したように、本実施形態によれば、トップ送風ノズル21に設けるリング状検知体30のリング状部31が車体表面に接触した際には、このリング状部31の変位を検知手段S1を介して検知することにより、トップ送風ノズル21の移動を停止して速やかに車体表面から離反させることができる。また、リング状部31が回動する方向に変位する場合には、ピン部材36が三角溝状ガイド部35の傾斜ガイド面35bに沿って摺動移動するので、リング状部31を滑らかに変位させることが可能になる。また、トップ送風ノズル21が傾斜しても、ピン部材36が底部ガイド面方向に付勢されて初期位置が固定されるので、リング状部31は変位せず、良好な初期位置(中立位置)を維持できる。従って、トップ送風ノズル21が振動または傾斜動作しても容易に変位せず誤検知しないリング状検知体30を備えた洗車機WAを得ることができる。   As described above, according to the present embodiment, when the ring-shaped portion 31 of the ring-shaped detector 30 provided in the top blowing nozzle 21 comes into contact with the vehicle body surface, the displacement of the ring-shaped portion 31 is detected by the detecting means S1. Therefore, the movement of the top blowing nozzle 21 can be stopped and quickly separated from the vehicle body surface. Further, when the ring-shaped portion 31 is displaced in the rotating direction, the pin member 36 slides and moves along the inclined guide surface 35b of the triangular groove-shaped guide portion 35, so that the ring-shaped portion 31 is smoothly displaced. It becomes possible to make it. Even if the top blowing nozzle 21 is inclined, the pin member 36 is urged toward the bottom guide surface and the initial position is fixed, so that the ring-shaped portion 31 is not displaced and a good initial position (neutral position). Can be maintained. Therefore, it is possible to obtain the car wash machine WA provided with the ring-shaped detection body 30 that is not easily displaced even if the top blowing nozzle 21 is vibrated or tilted and that is not erroneously detected.

次に、リング状部31の変位を検知する構成について図4B、図4Cを用いて説明する。   Next, the structure which detects the displacement of the ring-shaped part 31 is demonstrated using FIG. 4B and FIG. 4C.

図4Bに示すように、ベース部材33と対向面体34とは所定間隔W離間して一体に組み付けられている。例えば、長さがWのスペーサ39を介装して対向面体34をベース部材33にネジ固定することにより実現できる。また、38はスペーサ機能に加えてリング状部31を摺動支持する機能を有する所定長さの樹脂パイプから成るリング支持部38(38A、38B)である。すなわち、ベース部材33と対向面体34とは長さWのスペーサ39とリング支持部38(38A、38B)を介して所定間隔W離間して一体に組み付けられる。   As shown in FIG. 4B, the base member 33 and the facing surface body 34 are integrally assembled with a predetermined distance W therebetween. For example, it can be realized by screwing the opposing face member 34 to the base member 33 with a spacer 39 having a length W interposed therebetween. Reference numeral 38 denotes a ring support portion 38 (38A, 38B) made of a resin pipe having a predetermined length having a function of slidingly supporting the ring-shaped portion 31 in addition to the spacer function. In other words, the base member 33 and the opposed face member 34 are integrally assembled with a predetermined distance W apart via a spacer 39 having a length W and a ring support portion 38 (38A, 38B).

リング固定部材32は断面U字状の板金製であって、その外幅は所定間隔Wよりも少し小さく設計される。従って、リング固定部材32は、ベース部材33と対向面体34との間に摺動可能に嵌め込まれる構成となる。また、断面U字状の本体胴部を貫通するようにピン部材36が装着されている。   The ring fixing member 32 is made of sheet metal having a U-shaped cross section, and its outer width is designed to be slightly smaller than the predetermined interval W. Therefore, the ring fixing member 32 is configured to be slidably fitted between the base member 33 and the facing surface body 34. Further, a pin member 36 is mounted so as to penetrate the body trunk portion having a U-shaped cross section.

ピン部材36は、その両端部をベース部材33と対向面体34とから突出させる長さを有しており、一方の端部36bは対向面体34に設ける三角溝状ガイド部35Aに係合するガイド部材を成し、他方の端部36aはベース部材33に設ける三角溝状ガイド部35Bから突出して、検知手段S1により検知される被検知部を成す。   The pin member 36 has such a length that its both end portions protrude from the base member 33 and the opposing surface body 34, and one end portion 36 b is a guide that engages with a triangular groove-shaped guide portion 35 A provided on the opposing surface body 34. The other end portion 36a protrudes from a triangular groove-shaped guide portion 35B provided on the base member 33 to form a detected portion that is detected by the detecting means S1.

検知手段S1は、ピン部材36が底部ガイド面35aから離反した時にリング状部31の変位を検知する。この構成であれば、リング状部31が車体表面に接触した際には、底部ガイド面35a付近に位置して検知手段S1に近接した初期位置にあるピン部材36が底部ガイド面35aから離れる方向に移動するので、このピン部材36の変位を検知手段S1を介して検知することにより、トップ送風ノズル21の移動を停止して速やかに車体表面から離反させることができる。   The detecting means S1 detects the displacement of the ring-shaped portion 31 when the pin member 36 is separated from the bottom guide surface 35a. With this configuration, when the ring-shaped portion 31 comes into contact with the vehicle body surface, the pin member 36 located in the vicinity of the bottom guide surface 35a and in the initial position close to the detection means S1 is away from the bottom guide surface 35a. Therefore, by detecting the displacement of the pin member 36 through the detecting means S1, the movement of the top blowing nozzle 21 can be stopped and quickly separated from the vehicle body surface.

検知手段S1は、例えば、近接スイッチから成り、端部36aが所定距離以内にあればONとなり、所定距離以上離れたらOFFとなる。また、検知手段S1を設置しているベース部材33に設ける開口部は、単に、ピン部材36を突出させる開口部であってもよいが、対向面体34に設ける三角溝状ガイド部35Aと同じ形状の三角溝状ガイド部35Bの方が好ましい。これは、ベース部材33に三角溝状ガイド部35Bを設けた構成であれば、ピン部材36の両側の端部36a、36bを共に三角溝状ガイド部35A、35Bを介して、ピン部材36の両端を摺動可能に支持できるので、リング状検知体30をより安定して支持可能になるからである。   The detection means S1 is composed of, for example, a proximity switch, and is turned on when the end 36a is within a predetermined distance, and turned off when the distance is more than a predetermined distance. In addition, the opening provided in the base member 33 on which the detection means S1 is installed may simply be an opening from which the pin member 36 protrudes, but has the same shape as the triangular groove-shaped guide portion 35A provided in the facing surface body 34. The triangular groove-shaped guide portion 35B is more preferable. If this is a configuration in which the triangular groove guide portion 35B is provided in the base member 33, both end portions 36a and 36b of the pin member 36 are connected to the pin member 36 via the triangular groove guide portions 35A and 35B. This is because both ends can be slidably supported, so that the ring-shaped detector 30 can be supported more stably.

また、図中の想像線に示すカバー41を設けることが好ましい。カバー41は、ベース部材33と対向面体34を含む支持部SDの全体をカバーし、リング状部31の変位を可能にし、検知手段S1のケーブルS1aを挿通する開口部を備えた板金製から成る。このカバー41は、例えば、ベース部材33の側面板に設けるネジ固定部42を利用して固定できる。   Moreover, it is preferable to provide the cover 41 shown by the imaginary line in the figure. The cover 41 covers the entire support portion SD including the base member 33 and the opposed face body 34, enables the ring-shaped portion 31 to be displaced, and is made of a sheet metal provided with an opening through which the cable S1a of the detection means S1 is inserted. . The cover 41 can be fixed using, for example, a screw fixing portion 42 provided on the side plate of the base member 33.

図4Cに示すように、検知手段S1はベース部材33の三角溝状ガイド部35Bの直下に設置されており、三角溝状ガイド部35Bの底部ガイド面35a近辺に位置するピン部材36を検知する。また、付勢手段37を介してリング固定部材32をリング支持部38(38A、38B)に押さえ付けるように付勢しているので、リング固定部材32をベース部材33と対向面体34との間に摺動可能に嵌め込む構成であっても、ピン部材36が底部ガイド面35a付近に位置する状態に保持可能になる。   As shown in FIG. 4C, the detection means S1 is installed immediately below the triangular groove guide portion 35B of the base member 33, and detects the pin member 36 located near the bottom guide surface 35a of the triangular groove guide portion 35B. . Further, since the ring fixing member 32 is urged to be pressed against the ring support portion 38 (38A, 38B) via the urging means 37, the ring fixing member 32 is interposed between the base member 33 and the opposing face body 34. Even if it is configured to be slidably fitted into the pin member 36, the pin member 36 can be held in a state of being located near the bottom guide surface 35a.

また、ベース部材33は底面板33aと正面板33bに加えて、正面板33bの両側に側面板33cを有する折り曲げ構成の板金製であって、高い枠体強度を有すると共に、折り曲げ構成された側面板33cが正面板33bに取り付ける検知手段S1を保護する機能も発揮する。   The base member 33 is made of a sheet metal having a folded configuration having side plates 33c on both sides of the front plate 33b in addition to the bottom plate 33a and the front plate 33b. The function of protecting the detection means S1 attached to the front plate 33b by the face plate 33c is also exhibited.

次に、上記のように構成されるリング状部31の変位の様子について図5A〜図5Cを用いて説明する。図5Aはリング状部31が初期位置つまり中立位置にある状態を示し、図5Bはリング状部31が真上に移動した状態を示し、図5Cはリング状部31が回動した状態を示す。   Next, how the ring-shaped part 31 configured as described above is displaced will be described with reference to FIGS. 5A to 5C. FIG. 5A shows a state in which the ring-shaped portion 31 is in an initial position, that is, a neutral position, FIG. 5B shows a state in which the ring-shaped portion 31 has moved right above, and FIG. 5C shows a state in which the ring-shaped portion 31 has rotated. .

図5Aに示す初期位置においては、リング固定部材32がリング支持部38(38A、38B)に当接してリング状部31の両側が平行な姿勢である。この状態から上向きの外力が作用すると、例えば、トップ送風ノズル21が下降し過ぎてリング状部31の下方が車体の表面に当接した場合には、図5Bに示すように上向きの外力D1が作用し、付勢手段37の付勢力に抗してリング状部31とリング固定部材32が上方に移動し、ピン部材36が底部ガイド面35aから離れる。   In the initial position shown in FIG. 5A, the ring fixing member 32 is in contact with the ring support portion 38 (38A, 38B) and both sides of the ring-shaped portion 31 are in a parallel posture. When an upward external force is applied from this state, for example, when the top blowing nozzle 21 is lowered too much and the lower portion of the ring-shaped portion 31 comes into contact with the surface of the vehicle body, an upward external force D1 is generated as shown in FIG. 5B. The ring-shaped portion 31 and the ring fixing member 32 move upward against the urging force of the urging means 37, and the pin member 36 moves away from the bottom guide surface 35a.

この場合、ピン部材36は底部ガイド面35aから離れて三角溝状ガイド部35の空域内部に位置する。この際に、ピン部材36が底部ガイド面35aから離れるので、検知手段S1がOFFとなりリング状部31が変位したことを検知する。そして、この状態では、リング状部31の下方が車体表面に当接して生じる上向きの外力D1と付勢手段37による付勢力とが釣り合う位置にリング状部31が規定される。   In this case, the pin member 36 is located away from the bottom guide surface 35 a and inside the air space of the triangular groove-shaped guide portion 35. At this time, since the pin member 36 is separated from the bottom guide surface 35a, it is detected that the detecting means S1 is turned OFF and the ring-shaped portion 31 is displaced. In this state, the ring-shaped portion 31 is defined at a position where the upward external force D1 generated when the lower portion of the ring-shaped portion 31 comes into contact with the vehicle body surface and the urging force of the urging means 37 are balanced.

次に、リング状部31が横方向に外力を受けると、例えば、トップ送風ノズル21が水平方向に移動している時にリング状部31が車体表面や付属品などに接触した場合には、図5Cに示すようにリング状部31を回動する向きに外力D2が作用し、付勢手段37の付勢力に抗してリング状部31が側方に移動し、ピン部材36が底部ガイド面35aから離れて傾斜ガイド面35bを摺動移動する。   Next, when the ring-shaped portion 31 receives an external force in the lateral direction, for example, when the ring-shaped portion 31 comes into contact with the surface of the vehicle body or accessories when the top blowing nozzle 21 is moving in the horizontal direction, As shown in FIG. 5C, the external force D2 acts in the direction of rotating the ring-shaped portion 31, the ring-shaped portion 31 moves sideways against the urging force of the urging means 37, and the pin member 36 moves to the bottom guide surface. The inclined guide surface 35b is slid and moved away from 35a.

この際に、外力が図示するような左回りの外力D2であれば、リング固定部材32はリング支持部38Aとの当接状態を維持し他方のリング支持部38Bからは離れる方向に回動する。すなわち、リング支持部38Aとの当接部を回転中心にしてリング状部31が回転移動する。同時に、検知手段S1がOFFとなりリング状部31が異常に変位したことを検知する。   At this time, if the external force is a counterclockwise external force D2 as shown in the figure, the ring fixing member 32 maintains a contact state with the ring support portion 38A and rotates away from the other ring support portion 38B. . That is, the ring-shaped portion 31 rotates around the contact portion with the ring support portion 38A as the rotation center. At the same time, the detection means S1 is turned OFF and the ring-shaped portion 31 is detected to be abnormally displaced.

この場合、ピン部材36は傾斜ガイド面35bを摺動しながら移動するので、ピン部材36が移動中に引っ掛かったりして移動停止したりせず、スムーズに移動可能になる。そのために、本実施形態によれば、リング状部31の変位移動が容易にまた確実に行える構成となって好ましい。   In this case, since the pin member 36 moves while sliding on the inclined guide surface 35b, the pin member 36 does not get caught during movement and does not stop moving, and can move smoothly. Therefore, according to the present embodiment, it is preferable that the displacement movement of the ring-shaped portion 31 can be easily and reliably performed.

次に、トップ送風ノズル21が傾斜動作した時の様子について図6を用いて説明する。   Next, a state when the top blowing nozzle 21 is tilted will be described with reference to FIG.

図6に示すように、トップ送風ノズル21が図示しない傾斜装置により角度θ傾斜動作すると、リング状部31は付勢手段37の付勢力とリング支持部38(38A、38B)による2点支持により、ノズル本体21aの傾斜姿勢に応じた傾斜した姿勢を容易に、また確実に維持できる。   As shown in FIG. 6, when the top blowing nozzle 21 is tilted at an angle θ by a tilting device (not shown), the ring-shaped portion 31 is supported by two-point support by the biasing force of the biasing means 37 and the ring support portions 38 (38A, 38B). The inclined posture corresponding to the inclined posture of the nozzle body 21a can be easily and reliably maintained.

従って、この状態でトップ送風ノズル21が車体表面に接近し異常に接近し過ぎた場合には、リング状部31が先に車体表面に当接して容易に変位することになる。すなわち、ノズル本体21aが車体表面に接触する前に、この異常接近を検知できる。   Therefore, in this state, when the top blowing nozzle 21 approaches the surface of the vehicle body and approaches abnormally too much, the ring-shaped portion 31 comes into contact with the surface of the vehicle body first and is easily displaced. That is, this abnormal approach can be detected before the nozzle body 21a contacts the vehicle body surface.

リング状部31は、小径(例えば、直径が8〜12mm程度)のパイプ材から成り、接触時に車体を傷付けないように保護チューブにより被覆された従来公知の構成であればよい。また、その外形は円形でもよく、図示するようにノズル本体21aの周囲を略等しい間隔で取り囲む環状であってもよく、特には限定されない。   The ring-shaped portion 31 may be a conventionally known configuration that is made of a pipe material having a small diameter (for example, a diameter of about 8 to 12 mm) and is covered with a protective tube so as not to damage the vehicle body at the time of contact. Moreover, the outer shape may be circular, and as shown in the figure, it may be an annular shape that surrounds the periphery of the nozzle body 21a at substantially equal intervals, and is not particularly limited.

以上、説明したように、本発明は、被洗浄車両CAの表面に沿って移動しながら乾燥用空気を吹き出すトップ送風ノズル21を備え、被洗浄車両CAと洗車機本体1を前後方向に相対移動させながら被洗浄車両CAの洗車を行う洗車機WAであって、前記トップ送風ノズル21は、乾燥用空気を吹き付ける吹出部21bを備えたノズル本体21aと、該ノズル本体21aの下方、前方および後方に位置するリング状部31と、該リング状部31を保持するリング固定部材32と、当該リング状部31を前記ノズル本体21aに対する上方向と回動する方向に移動可能に支持する支持部SDと、前記リング状部31の変位を検知する検知手段S1と、を有するリング状検知体30と、を備え、前記支持部SDに、前記リング固定部材32に設けるピン部材36を摺動支持すると共に底部ガイド面35aと該底部ガイド面35aから前後の上方に傾斜して延設される傾斜ガイド面35bとを備えた三角溝状ガイド部35を設け、さらに、前記ピン部材36を前記底部ガイド面方向に付勢する付勢手段37を設けたことを特徴としている。 As described above, the present invention includes the top blowing nozzle 21 that blows drying air while moving along the surface of the vehicle CA to be cleaned, and relatively moves the vehicle CA and the car wash machine body 1 in the front-rear direction. The top washing nozzle 21 includes a nozzle body 21a having a blowing portion 21b for blowing drying air, and a lower side, a front side, and a rear side of the nozzle body 21a. A ring-shaped portion 31 positioned in the ring, a ring fixing member 32 that holds the ring-shaped portion 31, and a support portion SD that supports the ring-shaped portion 31 so as to be movable in an upward direction with respect to the nozzle body 21a. And a ring-shaped detector 30 having a detecting means S1 for detecting the displacement of the ring-shaped portion 31, provided on the ring fixing member 32 on the support portion SD. The triangular groove-shaped guide portion 35 having an inclined guide surface 35b which extends upwardly inclined in the front and rear from the bottom portion guide surface 35a and the bottom portion guide surface 35a with the pin member 36 slides support provided, further, An urging means 37 for urging the pin member 36 toward the bottom guide surface is provided.

この構成によれば、トップ送風ノズル21に設けるリング状検知体30のリング状部31が車体表面に接触した際には、このリング状部31の変位を検知手段S1を介して検知することにより、トップ送風ノズル21の移動を停止して速やかに車体表面から離反させることができる。また、リング状部31が回動する方向に変位する場合には、ピン部材36が三角溝状ガイド部35の傾斜ガイド面35bに沿って摺動移動するので、リング状部31を滑らかに変位させることが可能になる。また、ノズル本体21aが傾斜しても、ピン部材36が底部ガイド面方向に付勢されて初期位置が固定されるので、リング状部31は変位せず、良好な初期位置を維持できる。従って、トップ送風ノズル21が振動または傾斜動作しても容易に変位せず誤検知しないリング状検知体30を備えた洗車機WAを得ることができる。   According to this structure, when the ring-shaped part 31 of the ring-shaped detection body 30 provided in the top blowing nozzle 21 comes into contact with the vehicle body surface, the displacement of the ring-shaped part 31 is detected via the detection means S1. The movement of the top blower nozzle 21 can be stopped and quickly separated from the surface of the vehicle body. Further, when the ring-shaped portion 31 is displaced in the rotating direction, the pin member 36 slides and moves along the inclined guide surface 35b of the triangular groove-shaped guide portion 35, so that the ring-shaped portion 31 is smoothly displaced. It becomes possible to make it. Even if the nozzle body 21a is inclined, the pin member 36 is biased in the direction of the bottom guide surface and the initial position is fixed. Therefore, the ring-shaped portion 31 is not displaced, and a good initial position can be maintained. Therefore, it is possible to obtain the car wash machine WA provided with the ring-shaped detection body 30 that is not easily displaced even if the top blowing nozzle 21 is vibrated or tilted and that is not erroneously detected.

また、本発明によれば、リング状部31をリング固定部材32に固定し、このリング固定部材32の前記三角溝状ガイド部35の下方に位置する部分を2点支持し、この2点の中間部に付勢手段37を介装して初期位置に規定しているので、1個の付勢手段37によりリング状部31の初期位置(中立位置)を安定して維持可能なリング状検知体30になる。従って、トップ送風ノズル21が振動または傾斜動作しても、より確実に誤検知しない構成となって好ましい。   Further, according to the present invention, the ring-shaped portion 31 is fixed to the ring fixing member 32, and two portions of the ring fixing member 32 located below the triangular groove-shaped guide portion 35 are supported. Since the intermediate portion is provided with an urging means 37 to define the initial position, the ring-shaped detection that can stably maintain the initial position (neutral position) of the ring-shaped portion 31 by one urging means 37. It becomes the body 30. Therefore, even if the top blowing nozzle 21 is vibrated or tilted, it is preferable that the erroneous detection is not performed more reliably.

上記したように本発明によれば、リング状検知体のリング固定部材に設けるピン部材を底部ガイド面と傾斜ガイド面を有する三角溝状ガイド部により摺動可能に支持し、ピン部材を底部ガイド面方向に付勢しているので、トップ送風ノズルが振動または傾斜動作しても容易に変位せずに誤検知しないリング状検知体を備えた洗車機を得ることができる。   As described above, according to the present invention, the pin member provided on the ring fixing member of the ring-shaped detector is slidably supported by the triangular groove-shaped guide portion having the bottom guide surface and the inclined guide surface, and the pin member is supported by the bottom guide. Since it is biased in the surface direction, it is possible to obtain a car wash machine including a ring-shaped detector that is not easily displaced even if the top blowing nozzle vibrates or tilts and does not detect erroneously.

そのために、本発明に係る洗車機は、トップ送風ノズルを車体表面に安全に、また、確実に接近させて良好な乾燥効果を発揮することが求められる洗車場の洗車機に好適に適用される。   Therefore, the car wash machine according to the present invention is suitably applied to a car wash machine in a car wash where it is required to bring the top air blowing nozzle to the surface of the vehicle body safely and reliably and exhibit a good drying effect. .
