Description

本発明は、自動車や鉄道車両等の車体を洗浄する洗浄装置に関するものである。   The present invention relates to a cleaning device for cleaning a vehicle body such as an automobile or a railway vehicle.

この種の洗浄装置として、洗車処理装置を備えた洗車機本体を、車両の周囲に相対移動させ、この移動に伴い洗車処理装置を車体の被洗浄面に作用させる洗車機が知られている。この洗車機には、洗車処理装置として洗浄水を高圧で車体面に噴射する高圧ジェットノズル・車体面に高圧エアを吹き付ける乾燥ノズル等が装備されており、高圧ジェットによるジェット洗浄と、乾燥ノズルによるブロワ乾燥が実行可能となっている(例えば、特許文献1)。   As this type of cleaning apparatus, a car wash machine is known in which a car wash machine body provided with a car wash treatment apparatus is moved relative to the periphery of the vehicle, and the car wash treatment apparatus acts on a surface to be washed in accordance with this movement. This car wash machine is equipped with a high-pressure jet nozzle that sprays wash water onto the body surface at high pressure as a car wash treatment device, and a drying nozzle that blows high-pressure air onto the body surface. Blower drying is feasible (for example, Patent Document 1).

ところで、高圧ジェット洗浄には、次のような問題を有している。すなわち、ジェット洗浄は、多量の洗浄水を必要とするため、洗浄に掛かるランニングコストが高くなるとともに、連続した洗車を行うには、大容量のタンク設備が必要になる。また、高圧用ポンプが必要となるため、製品コストが高くなるとともに、定期的な保守点検による手間が掛かる。   By the way, the high-pressure jet cleaning has the following problems. That is, since jet cleaning requires a large amount of cleaning water, the running cost for cleaning increases, and a large-capacity tank facility is required for continuous car washing. In addition, since a high-pressure pump is required, the product cost increases and time and effort is required for periodic maintenance and inspection.

特許2546762号公報Japanese Patent No. 2546762

本発明は、大掛かりな設備を必要とせず、水量の消費を抑えてジェット洗浄を行うことができる洗浄装置を提供することを目的とするものである。   An object of this invention is to provide the washing | cleaning apparatus which does not require a large-scale installation and can perform jet washing | cleaning, suppressing consumption of water.

この課題を解決するため本発明は、本体フレームと車両とを相対移動し、移動に伴い車両の洗浄と乾燥を行う洗車機において、車体に沿って移動しながら被洗浄面に送風する送風ノズルと、該送風ノズルに取り付けられ送風ノズルからの送風に向けて洗浄液を散布する散水ノズルとを備え、該散水ノズルは、送風ノズルによる乾燥動作時に前記本体フレームが進行する方向に対して先行する側の送風ノズル外面に取り付けられており、送風ノズルの送風に散水ノズルの散水を合流させて洗浄液を車体の被洗浄面に吹き付ける洗浄動作と、送風ノズルの送風を車体の被洗浄面に吹き付ける乾燥動作を実行可能にした。
In order to solve this problem, the present invention relates to a car wash machine that relatively moves a main body frame and a vehicle and cleans and dries the vehicle as it moves. , and a water spray nozzle for spraying the washing liquid towards the air blowing from the blowing nozzle attached to the blasting nozzle, diverging water nozzle on the side preceding to the direction of the main frame during the drying operation by the air supply nozzle progresses It is attached to the outer surface of the air nozzle, and has a cleaning operation that combines the water from the water nozzle with the air blown from the air nozzle and blows the cleaning liquid onto the surface to be cleaned, and a drying operation that blows air from the air nozzle onto the surface to be cleaned. Made it executable.

送風ノズルは、車体上面に沿って移動しながら送風する上面ノズルと、車体側面に送風する側面ノズルを備え、該上面ノズル及び側面ノズルの乾燥動作時に前記本体フレームが進行する方向に対して先行する外面にそれぞれ前記散水ノズルを取り付けて送風ノズルからの送風に向けて洗浄液を散布するようにした。また、送風ノズルは、チャンバーと、該チャンバーに開口し車体の被洗浄面の幅寸法もしくは高さ寸法を広範囲で充足する細長いスリット状の送風口とを備え、該送風口からの送風に向けて散水ノズルからの散水を合流させるようにした。 The blowing nozzle includes an upper surface nozzle that blows while moving along the upper surface of the vehicle body, and a side nozzle that blows air to the side surface of the vehicle body, and precedes the direction in which the main body frame advances during the drying operation of the upper surface nozzle and the side nozzle. The said watering nozzle was attached to the outer surface, respectively, and the washing | cleaning liquid was sprayed toward the ventilation from a ventilation nozzle. The blower nozzle includes a chamber and an elongated slit-like blower opening that opens into the chamber and satisfies a wide width or height of the surface to be cleaned of the vehicle body, and blows air from the blower. The watering from the watering nozzle was merged.

散水ノズルは、主パイプと、主パイプに所定間隔で複数配列され、扇状の広角散水を行うノズルチップとを設け、該複数のノズルチップから散布された液流が幅方向もしくは高さ方向に連続した状態で送風ノズルの送風に合流させるようにした。   The watering nozzle is provided with a main pipe and a plurality of nozzle chips arranged at predetermined intervals on the main pipe and performing fan-shaped wide-angle water spraying, and the liquid flow sprayed from the plurality of nozzle chips is continuous in the width direction or the height direction. In such a state, the air was blown from the air blowing nozzle.

本発明によれば、高圧ジェット洗浄に相当する洗浄効果が少量の洗浄水で得られるため、ランニングコストを抑えることができるとともに、連続した洗浄が可能になり、洗浄の回転率が向上する。また、大掛かりな設備が不要となるため、製品コストを抑えることができるとともに、保守点検に掛かる手間が削減される。更に、散水ノズルを送風ノズルでの乾燥動作時に本体フレームが進行する方向に対して、先行する側に取り付けられているので、散水ノズルからの液滴で乾燥後の車体を濡らすことがない。 According to the present invention, since a cleaning effect corresponding to high-pressure jet cleaning can be obtained with a small amount of cleaning water, running cost can be suppressed, continuous cleaning is possible, and the rotation rate of cleaning is improved. In addition, since no large-scale equipment is required, the product cost can be reduced and the labor required for maintenance and inspection can be reduced. Furthermore, since the water spray nozzle is attached to the front side with respect to the direction in which the main body frame advances during the drying operation with the air blowing nozzle, the dried vehicle body is not wetted by the droplets from the water spray nozzle.

At this time, it is attached to the preceding side with respect to the direction in which the main body frame 1 travels during the drying operation at the blow nozzle 15 so as not to wet the dried vehicle body with the droplets from the watering nozzle 16. Since the nozzle tip 21 of the watering nozzle 16 is a wide-angle injection type that sprays in a fan shape, as shown in FIG. 3, the injection from the nozzle tips 21 arranged in a plurality in the main pipe 20 is continuous with each other in the width direction. Thus, the distance, the arrangement pitch and the injection angle from the blowing port 19 of the blowing nozzle 15 are determined and arranged so as to merge with the blowing from the blowing nozzle 15.

次に、図6及び7を用いて側面処理装置9の構造について説明する。
側面処理装置9は、図6に示すように、車体側面に高圧のエアを吹き付ける送風ノズル34と、送風ノズル34からの送風に洗浄水を合流して車体側面に高圧の洗浄水を噴射する散水ノズル35とを備えている。
Next, the structure of the side processing apparatus 9 will be described with reference to FIGS.
As shown in FIG. 6, the side surface processing device 9 includes a blower nozzle 34 that blows high-pressure air on the side surface of the vehicle body, and a water spray that joins the wash water to the air blown from the blower nozzle 34 and injects the high-pressure wash water onto the side surface of the vehicle body. And a nozzle 35.

送風ノズル34は、自動車の車高を広域でカバーする長さ寸法を有し、一側面にいくに従って内部空間の断面積が小さくなるよう平面視略三角形に形成するとともに、下面にいくに従って内部空間の断面積が小さくなるよう他側面を傾斜させたチャンバー36と、チャンバー36の上面にダクトホース11を接続する給気筒37と、チャンバー36の一側面に開口したスリット状の送風口38とで形成され、ブロワ装置10,10からダクトホース11を通じて供給される高圧エアを車体側面に吹き付けるものである。   The blower nozzle 34 has a length dimension that covers the vehicle height in a wide area, and is formed in a substantially triangular shape in plan view so that the cross-sectional area of the internal space decreases as it goes to one side surface, and the internal space as it goes to the lower surface. Formed with a chamber 36 whose other side surface is inclined so that the cross-sectional area of the chamber 36 becomes smaller, a supply cylinder 37 that connects the duct hose 11 to the upper surface of the chamber 36, and a slit-like air vent 38 that opens on one side surface of the chamber 36. The high pressure air supplied from the blower devices 10 and 10 through the duct hose 11 is blown to the side surface of the vehicle body.

散水ノズル35は、中空の主パイプ39と、主パイプ39に所定間隔で取り付けられる複数の広角噴射型ノズルチップ40と、主パイプ39の上端位置に給水ホース14を接続する給水口41と、主パイプ38の下端に取り付けられる固定端42とで形成され、給水ポンプ12から給水ホース14を通じて供給される洗浄水を送風ノズル34からの送風に合流させて車体側面に吹き付けるものである。   The watering nozzle 35 includes a hollow main pipe 39, a plurality of wide-angle injection nozzle tips 40 attached to the main pipe 39 at predetermined intervals, a water supply port 41 that connects the water supply hose 14 to the upper end position of the main pipe 39, It is formed with a fixed end 42 attached to the lower end of the pipe 38, and the washing water supplied from the water supply pump 12 through the water supply hose 14 is merged with the air blown from the blower nozzle 34 and blown to the side of the vehicle body.

散水ノズル35は、送風ノズル34のチャンバー36の一側面にブラケット43を介して取り付けられている。このとき、送風ノズル34での乾燥動作時に本体フレーム1が進行する方向に対して、先行する側に取り付けられている。散水ノズル35のノズルチップ40は、扇状に散水する広角噴射型であるので、主パイプ39に複数配列された各ノズルチップ40からの噴射が互いに連なった状態で送風ノズル34からの送風に合流するように、送風ノズル34の送風口38からの距離・配列ピッチ及び噴射角度が決定されて配置されている。   The watering nozzle 35 is attached to one side surface of the chamber 36 of the blower nozzle 34 via a bracket 43. At this time, it is attached to the preceding side with respect to the direction in which the main body frame 1 advances during the drying operation at the blow nozzle 34. The nozzle tip 40 of the water spray nozzle 35 is a wide-angle spray type that sprays in a fan shape, so that the spray from each nozzle chip 40 arranged in the main pipe 39 joins the air blow from the blow nozzle 34 in a state where they are connected to each other.

FIG. 8 is a block diagram showing the control system.
A control unit 50 includes a CPU 51 that performs arithmetic processing, a memory 52 that stores programs and various data, and an input / output interface 53. The input / output interface 53 includes a travel encoder 4, a body position sensor 5, and a vehicle shape detection device 7. The blower device 10, the feed water pump 12, the lift motor 32, and the lift encoder 33 are connected.

以上のように構成する洗浄装置の動作について、図9及び図10を用いて説明する。図9は上面処理装置8、図10は側面処理装置9の動作を示している。ここでは、本体フレーム1が1往復する間に洗浄と乾燥を行う洗車工程を例に説明する。むろん、この洗車工程に限定されるものではなく、本体フレーム1を2往復以上走行させたり、1.5往復単位で走行させて洗車工程を実行するものでもよい。尚、1.5往復単位で走行させる場合、洗車後は自動車を前進で退車させるドライブスルー方式を採用することができる。   The operation of the cleaning apparatus configured as described above will be described with reference to FIGS. FIG. 9 shows the operation of the upper surface processing apparatus 8, and FIG. Here, a car wash process in which cleaning and drying are performed while the main body frame 1 reciprocates once will be described as an example. Of course, the present invention is not limited to this car wash process, and the car wash process may be executed by causing the main body frame 1 to travel two or more reciprocations or by 1.5 reciprocation units. In the case of traveling in 1.5 reciprocating units, a drive-through system in which the automobile is moved forward after washing can be adopted.

本体フレーム1が後進限界位置に待機している状態で、自動車を所定の停車位置に停車させると、本体フレーム1が往行(前進)を開始する。往行に伴い、制御部50では、走行エンコーダ4のパルス信号をカウントして本体フレーム1の走行位置を検出するとともに、このパルス信号をトリガにして車形検出装置7から自動車の車高位置を取り込み、車形データを作成していく。   When the vehicle is stopped at a predetermined stop position while the main body frame 1 is waiting at the reverse limit position, the main body frame 1 starts going forward. As the vehicle travels, the control unit 50 counts the pulse signal of the travel encoder 4 to detect the travel position of the main body frame 1 and uses the pulse signal as a trigger to determine the vehicle height position from the vehicle shape detection device 7. Import and create car shape data.

図9(a)に示すように、上面処理装置8は、作成される車形データに基づいて自動車の上面形状に沿って昇降制御され、ブロワ装置10,10と給水ポンプ12を作動して高圧洗浄水を噴射して自動車上面の洗浄を行う。また、図10(a)に示すように、側面処理装置9は、ブロワ装置10,10と給水ポンプ12を作動して高圧洗浄水を噴射して自動車側面の洗浄を行う。   As shown in FIG. 9A, the upper surface processing device 8 is controlled to move up and down along the upper surface shape of the vehicle based on the generated vehicle shape data, and operates the blower devices 10 and 10 and the water supply pump 12 to increase the pressure. The top surface of the automobile is cleaned by spraying cleaning water. Moreover, as shown to Fig.10 (a), the side surface processing apparatus 9 operates the blower apparatuses 10 and 10 and the feed water pump 12, and injects high-pressure washing water, and cleans the side surface of a motor vehicle.

このとき、各散水ノズル16,35からの散水は、各送風ノズル15,34からの送風に合流して高圧化するとともに、微細化して洗浄面に作用し、少ない水量であっても十分な洗浄力が与えられる。また、散水ノズル16,35は、図3及び6に示すように、隣接するノズルチップ21,40からの散水が互いに連なった状態で送風ノズル15,34からの送風に合流するように配置されているので、洗浄面にムラなく作用し、洗い残しが生じない洗浄が実現される。   At this time, the water sprayed from the water spray nozzles 16 and 35 is combined with the air blown from the air blowing nozzles 15 and 34 to increase the pressure, and the water spray is refined and acts on the cleaning surface. Power is given. Further, as shown in FIGS. 3 and 6, the watering nozzles 16 and 35 are arranged so as to join the air blown from the air blowing nozzles 15 and 34 in a state where watering from the adjacent nozzle chips 21 and 40 are connected to each other. Therefore, it is possible to achieve cleaning that acts evenly on the cleaning surface and does not leave unwashed.

こうして上面処理装置8及び側面処理装置9による洗浄を行いながら本体フレーム1を走行させ、本体フレーム1が前進限界位置まで達したら、1往行での洗浄工程を終了する。 Thus, the main body frame 1 is caused to travel while being cleaned by the upper surface processing device 8 and the side surface processing device 9, and when the main body frame 1 reaches the forward limit position, the cleaning process in one way is finished.

本体フレーム1が前進限界位置に達したら、本体フレーム1が復行(後進)を開始する。復行に伴い、制御部50では、走行エンコーダ4のパルス信号をカウントして本体フレーム1の走行位置を検出しながら、往行時に検出した車形データに基づいて、図9(b)に示すように、上面処理装置8を自動車の上面形状に沿って昇降制御し、ブロワ装置10,10のみを作動して上面処理装置8の送風ノズル15からの送風を自動車上面に吹き付けて乾燥を行う。また、図10(b)に示すように、側面処理装置9の送風ノズル34からの送風を自動車側面に吹き付けて乾燥を行う。   When the main body frame 1 reaches the forward limit position, the main body frame 1 starts going backward (reverse). As the vehicle travels backward, the control unit 50 counts the pulse signal of the travel encoder 4 to detect the travel position of the main body frame 1, and based on the vehicle shape data detected during the forward travel, as shown in FIG. As described above, the upper surface processing apparatus 8 is controlled to move up and down along the shape of the upper surface of the automobile, and only the blower apparatuses 10 and 10 are operated to blow the air from the blowing nozzle 15 of the upper surface processing apparatus 8 onto the upper surface of the automobile and perform drying. Moreover, as shown in FIG.10 (b), the ventilation from the ventilation nozzle 34 of the side surface processing apparatus 9 is sprayed on the side surface of a motor vehicle, and it dries.

こうして上面処理装置8及び側面処理装置9による乾燥を行いながら本体フレーム1を走行させ、本体フレーム1が後進限界位置まで達したら、1復行での乾燥工程を終了する。   In this way, the main body frame 1 is caused to travel while being dried by the upper surface processing device 8 and the side surface processing device 9, and when the main body frame 1 reaches the reverse limit position, the drying process in one return is ended.

以上のように、本発明は、車体の被洗浄面に送風する送風ノズルと、送風ノズルからの送風に向けて洗浄水を散布する散水ノズルとを備え、送風ノズルからの送風に散水ノズルからの洗浄水を合流させた洗浄液を車体の被洗浄面に高圧で吹き付ける洗浄動作を実行可能にしたものである。   As described above, the present invention includes a blowing nozzle that blows air to the surface to be cleaned of the vehicle body, and a water spray nozzle that sprays cleaning water toward the air blown from the air blowing nozzle. A cleaning operation in which the cleaning liquid combined with the cleaning water is sprayed at a high pressure on the surface to be cleaned of the vehicle body can be executed.

この構成は、上記実施例に限定されるものではなく、種々の実施態様が考えられる。例えば、洗浄対象は、自動車に限らず、鉄道車両等にも利用することができる。また、洗浄ブラシを備えた門型洗車機に搭載し、洗浄ブラシで車体面をブラッシング洗浄する前に、車体面に付着した砂や泥を除去する予備洗浄等を行うことができる。門型洗車機に元々装備されている上面乾燥ノズル及び側面乾燥ノズルにそれぞれ散水ノズルを取り付け、各乾燥ノズルからの送風に散水ノズルからの洗浄水を合流させて自動車車体に吹き付けることで高圧洗浄が可能となるため、高圧ポンプやノズル揺動機構等の高価な設備が不要となり、水量を大幅に削減することができる。   This configuration is not limited to the above embodiment, and various embodiments are conceivable. For example, the cleaning object can be used not only for automobiles but also for railway vehicles. In addition, it can be mounted on a portal type car wash machine equipped with a cleaning brush, and before the body surface is brushed and cleaned with the cleaning brush, preliminary cleaning or the like for removing sand and mud adhering to the surface of the vehicle body can be performed. Water spray nozzles are attached to the top drying nozzle and side drying nozzle originally installed in the portal type car wash machine, and the washing water from the spray nozzle is combined with the air blown from each drying nozzle and sprayed onto the car body to perform high-pressure washing. Therefore, expensive equipment such as a high-pressure pump and a nozzle swing mechanism is unnecessary, and the amount of water can be greatly reduced.

また、送風ノズルの形状は、洗浄面への洗浄効果等を考慮して種々の実施態様が考えられる。例えば、送風ノズルのチャンバー内における給気筒直下に整流子を配置して給気筒から供給される高圧エアをチャンバー内の長手方向に分散させ、送風口からの送風を均一化を図ったものや、断面を四角形状にしてチャンバー内の拡散性を高め、送風口からの送風を均一化を図ったもの等も効果的である。   Moreover, various embodiments can be considered for the shape of the blow nozzle in consideration of the cleaning effect on the cleaning surface and the like. For example, a commutator is disposed immediately below the supply cylinder in the chamber of the blow nozzle to disperse the high-pressure air supplied from the supply cylinder in the longitudinal direction in the chamber, so that the air blown from the blow port is made uniform, It is also effective to use a rectangular cross section to increase the diffusibility in the chamber and to make the air from the air outlet uniform.

また、上面処理装置を前後方向に揺動可能にし、車体の傾斜に応じて揺動させたり、車体部位に応じて揺動させると効果的である。また、側面処理装置を車体の幅方向に開閉自在にし、車体の傾斜に応じて車体に接離させると効果的である。   In addition, it is effective to make the upper surface processing apparatus swingable in the front-rear direction so as to swing according to the inclination of the vehicle body or according to the body part. Further, it is effective to make the side surface processing device openable and closable in the width direction of the vehicle body, and to contact and separate from the vehicle body according to the inclination of the vehicle body.

また、散水ノズルから散布される液流は、洗浄水に限らず、液剤やワックス、撥水剤等のケミカルでもよい。この場合、同一のノズルからタイミングをずらして異なる液流を散布してもよいし、それぞれ専用の散水ノズルを設けてもよい。   Further, the liquid flow sprayed from the watering nozzle is not limited to cleaning water, but may be chemicals such as liquid, wax, water repellent and the like. In this case, different liquid flows may be sprayed from the same nozzle at different timings, or a dedicated watering nozzle may be provided.
