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. Furthermore, a car wash machine having a lower surface cleaning device for cleaning the lower surface of the vehicle to be cleaned is also known.

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.

操作パネルやリモートパネルを備える洗車機の一例について図9を用いて説明する。この洗車機WBは、複数のブラシを備える洗浄部材と、ブロワと複数の送風ノズルを備える乾燥部材とを一体に装着し、被洗浄車両CAを跨ぐように門型とされる洗車機本体1を備えた構成であり、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、複数の貯液タンクに貯留された液剤をそれぞれ水により希釈して前記被洗浄車両へ噴射して、前記被洗浄車両の洗車を行う。   An example of a car wash machine including an operation panel and a remote panel will be described with reference to FIG. This car wash machine WB includes a car wash machine main body 1 that is integrally mounted with a cleaning member having a plurality of brushes, and a drying member having a blower and a plurality of blower nozzles, and has a gate shape so as to straddle the vehicle to be cleaned CA. The liquid agent stored in the plurality of liquid storage tanks is diluted with water and sprayed to the vehicle to be cleaned while relatively moving the vehicle to be cleaned CA and the car wash machine body 1 in the front-rear direction. The vehicle to be cleaned is washed.

例えば、洗車機本体1が、車輪3を介してレール2上に沿って走行移動する構成とし、被洗浄車両CAを、該被洗浄車両CAを跨ぐ門型とされる洗車機の左右一対のレール間の所定の位置に停車して、洗車機本体1に設置する操作パネル7もしくは洗車機本体1から離れた位置に設置するリモートパネル7Aに、所望の洗車モードを設定し、スタートボタンを操作して、洗車を開始する。   For example, the car wash machine main body 1 is configured to travel and move along the rails 2 via the wheels 3, and the pair of left and right rails of the car wash machine in which the vehicle to be cleaned CA is a gate type straddling the vehicle to be cleaned CA. Set the desired car wash mode on the operation panel 7 installed in the car wash machine body 1 or the remote panel 7A installed at a position away from the car wash machine body 1 and operate the start button. And start the car wash.

門型の洗車機本体1は、被洗浄車両CAを洗浄するブラシとして、例えば、被洗浄車両CAの上面を洗浄するトップブラシ4と、被洗浄車両CAの両側面と前後面を洗浄する左右一対のサイドブラシ5と、被洗浄車両CAの両側面下部を洗浄する左右一対のロッカーブラシ6を備えている。   The portal-type car wash machine main body 1 is, for example, a top brush 4 that cleans the upper surface of the vehicle CA to be cleaned, and a pair of left and right surfaces that clean both side surfaces and front and rear surfaces of the vehicle CA to be cleaned. Side brush 5 and a pair of left and right rocker brushes 6 for cleaning the lower portions of both side surfaces of the vehicle CA to be cleaned.

また、ブラッシングの際に使用する洗浄水や各種液剤を噴射する各種ノズルや各種液剤を貯液する貯液タンクを備えている。各種液剤を貯液する複数の貯液タンクは、洗車機本体1に設けられるタンク収納部60に収納されており、電磁式の開閉弁と副給水ホースを備える分配配管部61を介して各ノズルに分配している。液剤を噴射するノズルとしては、例えば、第一浄水ノズル11、第一洗剤ノズル12、第二浄水ノズル13、撥水コートノズル14、第二洗剤ノズル15、ワックスノズル16などが配設されている。   In addition, there are provided various nozzles for spraying cleaning water and various liquid agents used for brushing and a liquid storage tank for storing various liquid agents. A plurality of liquid storage tanks for storing various liquid agents are stored in a tank storage unit 60 provided in the car wash machine body 1, and each nozzle is provided via a distribution pipe unit 61 including an electromagnetic on-off valve and a sub-water supply hose. Is distributed. As nozzles for injecting the liquid agent, for example, a first water purification nozzle 11, a first detergent nozzle 12, a second water purification nozzle 13, a water repellent coating nozzle 14, a second detergent nozzle 15, a wax nozzle 16, and the like are disposed. .

さらに、乾燥のために、ブロワ20と該ブロワ20からの送風を吹き付ける昇降自在なトップ送風ノズル21と左右一対のサイド送風ノズル22を備えている。また、洗車機本体1に配設する操作パネル7、もしくは、洗車機本体1から離れた位置に設置するリモートパネル7Aを介して、洗車機WBの駆動条件を設定し、設定された条件に基づいて洗車機WBを駆動する構成としている。8は、被洗浄車両CAの有無および車高を検知するセンサであって、例えば、光電センサや超音波を利用したソニックセンサが好適に用いられる。   Further, for drying, a blower 20, a freely movable top blower nozzle 21 that blows blown air from the blower 20, and a pair of left and right side blower nozzles 22 are provided. Further, the driving condition of the car wash machine WB is set through the operation panel 7 disposed in the car wash machine body 1 or the remote panel 7A installed at a position away from the car wash machine body 1, and based on the set condition. The car wash machine WB is driven. Reference numeral 8 denotes a sensor for detecting the presence / absence of the vehicle to be cleaned CA and the vehicle height, and for example, a photoelectric sensor or a sonic sensor using ultrasonic waves is preferably used.

操作パネル7やリモートパネル7Aには、水洗いモードや、洗剤を用いた洗浄モードや、ワックスを塗布するワックスモードや、撥水剤をコートする撥水モードなどの各種洗車モードを選択する選択ボタンや、ブラシの回転数を制御するブラシ回転スイッチや、スタート・ストップボタンなどが設けられている。   On the operation panel 7 and the remote panel 7A, there are selection buttons for selecting various car washing modes such as a water washing mode, a washing mode using a detergent, a wax mode for applying a wax, and a water repellent mode for coating a water repellent. A brush rotation switch for controlling the number of rotations of the brush, a start / stop button, and the like are provided.

また、洗車機本体1を、洗浄部材を備えた洗浄機本体と乾燥部材を備えた乾燥機本体との別体として、それぞれが、被洗浄車両CAを跨ぐように門型とされ、被洗浄車両CAと洗浄機本体と乾燥機本体とを前後方向に相対移動させながら、被洗浄車両CAの洗車を行う構成の洗車機も知られている。この構成であっても、各種ブラシと各種ノズルを備え、操作パネル7もしくはリモートパネル7Aを備えていることは同じである。   In addition, the car wash machine main body 1 is separated into a washing machine main body provided with a cleaning member and a dryer main body provided with a drying member, each of which has a gate shape so as to straddle the vehicle CA to be cleaned. There is also known a car wash machine configured to wash the vehicle to be cleaned CA while relatively moving the CA, the washing machine main body, and the dryer main body in the front-rear direction. Even if it is this structure, it is the same that it is provided with various brushes and various nozzles, and is provided with the operation panel 7 or the remote panel 7A.

上記の門型洗車機を用いて被洗浄車両CAの表面を洗車することはできるが、下面は洗車できないので、この門型洗車機に下面洗浄装置を併設した洗車機が提案されている。例えば、被洗浄車両の下面を洗浄するための放水ノズルを備えるキャリア(台車)を洗車機本体と並行して走行させ、洗車機本体に備えた検出手段で車両端部を検出したタイミングに基づいて放水ノズルによる放水を制御するとした洗車機における下回り洗浄装置が既に提案されている(例えば、特許文献1参照)。   Although the surface of the to-be-cleaned vehicle CA can be washed using the above-described gate-type car wash machine, the lower surface cannot be washed. Therefore, a car wash machine in which a lower-surface washing device is added to this gate-type car wash machine has been proposed. For example, based on the timing at which a carrier (cart) having a water discharge nozzle for cleaning the lower surface of the vehicle to be cleaned is run in parallel with the car wash machine body and the vehicle end is detected by the detection means provided in the car wash machine body. A lower cleaning device in a car wash machine that controls water discharge by a water discharge nozzle has already been proposed (see, for example, Patent Document 1).

また、洗車機に付設される洗車装置であって、被洗浄車両の前端および後端の位置を検出する手段と、下面洗浄用の台車の走行位置を検出する手段と、検知される車両の前後端位置と台車の走行位置とに基づいて下面洗浄を制御する手段を備えた洗車装置も既に提案されている(例えば、特許文献2参照)。   Also, a car wash apparatus attached to the car wash machine, the means for detecting the positions of the front end and the rear end of the vehicle to be cleaned, the means for detecting the traveling position of the bottom cleaning carriage, and the front and rear of the vehicle to be detected A car wash apparatus having means for controlling the bottom surface cleaning based on the end position and the traveling position of the carriage has already been proposed (see, for example, Patent Document 2).

門型の洗車機本体が備えるサイドブラシを被洗浄車両の側面に当接させて回転させながら洗車機本体を走行させることで、被洗浄車両の側面を洗車することができる。また、この洗車機本体の走行移動に連動して移動する下面洗浄装置を用いて、被洗浄車両の下面を洗浄することができる。しかし、下面洗浄装置に設置する洗浄ノズルは、上向きに洗浄水を噴射するので、被洗浄車両のサイズや下面洗浄装置の配設位置のばらつきによって、被洗浄車両の底面部から外れた位置に向けて噴射して、周囲に洗浄水を吹き付けてしまうことがある。   The side surface of the vehicle to be cleaned can be washed by running the vehicle body while the side brush provided in the portal-type car washer is in contact with the side surface of the vehicle to be cleaned and rotating. Further, the lower surface of the vehicle to be cleaned can be cleaned using the lower surface cleaning device that moves in conjunction with the traveling movement of the car wash machine main body. However, since the cleaning nozzle installed in the bottom surface cleaning apparatus injects cleaning water upward, it is directed to a position away from the bottom surface of the target vehicle due to variations in the size of the vehicle to be cleaned and the position of the bottom surface cleaning apparatus. May spray and spray cleaning water around it.

また、下面洗浄装置の位置と被洗浄車両の前端部・後端部の位置をそれぞれ検知して、周囲に洗浄水を撒き散らさず被洗浄車両の下面部を正確に洗浄することは可能であるが、それぞれの位置を検知する検知センサや、検知センサが検知した情報から下面洗浄装置の走行と噴射動作を制御する制御装置を設けることが必要となって、設備コストが高くなってしまうので好ましくない。   In addition, it is possible to detect the position of the lower surface cleaning device and the position of the front end portion and the rear end portion of the vehicle to be cleaned, respectively, and accurately clean the lower surface portion of the vehicle to be cleaned without spraying cleaning water around it. However, it is necessary to provide a detection sensor for detecting each position and a control device for controlling the running and injection operation of the lower surface cleaning device from information detected by the detection sensor, which is preferable because the equipment cost increases. Absent.

また、設置スペースなどの関係で被洗浄車両を往復移動させて洗車するためにコンベア装置を設置する構成では、コンベア駆動部に設ける駆動シャフトや従動シャフトとの干渉を考慮する必要が生じ、両シャフト間の両シャフトに干渉しない領域に下面洗浄装置の駆動領域を設けるか、両シャフトに干渉しない深さ領域に下面洗浄装置の駆動領域を設けることが必要となる。   In addition, in the configuration in which the conveyor device is installed to reciprocate and wash the vehicle to be cleaned due to the installation space and the like, it is necessary to consider interference with the drive shaft and the driven shaft provided in the conveyor drive unit. It is necessary to provide a drive region for the lower surface cleaning device in a region that does not interfere with both shafts, or to provide a drive region for the lower surface cleaning device in a depth region that does not interfere with both shafts.

両シャフトに干渉しない領域を下面洗浄装置の駆動領域とする構成では、コンベア装置の長さが、実際に被洗浄車両を洗浄するのに必要な長さ以上になってしまい、設備コストが高くなったり、洗車機設置スペースの効率が悪化したりする。また、両シャフトに干渉しない深さ領域に下面洗浄装置の駆動領域を設ける構成では、下面洗浄台車と被洗浄車両の底面との距離が離れてしまい、洗浄水を噴射する圧力が弱くなって好ましくない。   In the configuration in which the area that does not interfere with both shafts is used as the drive area of the lower surface cleaning device, the length of the conveyor device becomes longer than the length required for actually cleaning the vehicle to be cleaned, which increases the equipment cost. Or the efficiency of the car wash machine installation space deteriorates. Further, in the configuration in which the drive region of the lower surface cleaning device is provided in a depth region that does not interfere with both shafts, the distance between the lower surface cleaning carriage and the bottom surface of the vehicle to be cleaned is increased, and the pressure for injecting cleaning water is preferably reduced. Absent.

また、洗車機を設置するレイアウトやコンベア装置の配設配置などによっては、被洗浄車両の先端部にサイドブラシを当接させて洗車を開始する位置がコンベア装置の駆動シャフト設置位置近辺となる場合がある。このような場合には、下面洗浄装置が被洗浄車両の先端部から離れた位置に設置されることがあり、サイドブラシに連動させて移動させる構成では、下面洗浄装置が対応できない領域が生じて問題となる。   In addition, depending on the layout of the car wash machine and the arrangement of the conveyor device, the position where the side brush is brought into contact with the tip of the vehicle to be cleaned and the car wash starts is near the drive shaft installation position of the conveyor device. There is. In such a case, the lower surface cleaning device may be installed at a position away from the front end of the vehicle to be cleaned, and there is an area that the lower surface cleaning device cannot handle in the configuration that moves in conjunction with the side brush. It becomes a problem.

また、下面洗浄台車を単独で駆動して下面洗浄を行う構成では、下面洗浄台車に走行移動距離を検知するためのパルスセンサを設ける必要が生じ設備コストが掛かってしまうので好ましくない。また、パルスセンサを設けた構成であってもパルスセンサに不良が生じると、位置情報が実際の位置とずれてしまい、車両を外れた領域で噴射して問題となる。   Further, in the configuration in which the lower surface cleaning cart is driven alone to perform the lower surface cleaning, it is necessary to provide a pulse sensor for detecting the travel distance in the lower surface cleaning cart, which is not preferable. Further, even if the pulse sensor is provided, if a defect occurs in the pulse sensor, the position information is shifted from the actual position, and there is a problem in injecting in a region outside the vehicle.

そのために、被洗浄車両の下面を洗浄するために設ける下面洗浄装置は、洗車機やコンベア装置の設置レイアウトに影響を受けずに配設可能であると共に、被洗浄車両を外れた領域では洗浄水を噴射せず、洗い残しを残さないで車両の下面全体を洗浄可能で、パルスセンサなどを設けずにサイドブラシと連動して洗浄可能であることが好ましい。   For this reason, the lower surface cleaning device provided for cleaning the lower surface of the vehicle to be cleaned can be disposed without being affected by the installation layout of the car wash machine and the conveyor device, and in the area outside the vehicle to be cleaned It is preferable that the entire lower surface of the vehicle can be cleaned without spraying and leaving no residue, and can be cleaned in conjunction with the side brush without providing a pulse sensor or the like.

本発明は、上記問題点に鑑み、被洗浄車両の下面を洗浄する下面洗浄装置を有する洗車機において、パルスセンサを備えていない簡単な構成であっても、洗車機やコンベア装置の設置レイアウトに影響を受けずに配設可能であり、被洗浄車両を外れた領域では洗浄水を噴射せず、洗い残しを残さないで車両の下面全体を確実に洗浄可能な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 car wash machine having a lower surface cleaning device for cleaning the lower surface of a vehicle to be cleaned, even in a simple configuration that does not include a pulse sensor. An object is to provide a car wash machine that can be installed without being affected, and that can wash the entire lower surface of the vehicle without spraying washing water and leaving the unwashed area in an area outside the vehicle to be washed. And

上記目的を達成するために本発明は、被洗浄車両の側面および前面、後面を洗浄するサイドブラシと、被洗浄車両の下面を洗浄する下面洗浄装置を備え、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洗車を行う洗車機であって、前記洗車機本体の前記サイドブラシ設置部位と前後方向に所定距離離れた位置に前記下面洗浄装置の待機位置を設け、前記下面洗浄装置は、被洗浄車両の下部の長手方向に沿って移動可能な下面洗浄台車と下面噴射ノズルとを備えると共に、前記洗車機本体の走行移動に連動して移動することを特徴としている。   In order to achieve the above object, the present invention comprises a side brush for cleaning the side, front, and rear of a vehicle to be cleaned, and a lower surface cleaning device for cleaning the lower surface of the vehicle to be cleaned. A car wash machine that performs a car wash while relatively moving in a direction, wherein a stand-by position of the lower surface cleaning device is provided at a predetermined distance in the front-rear direction from the side brush installation portion of the car wash machine body, and the lower surface cleaning device In addition, the vehicle is provided with a lower surface cleaning carriage and a lower surface injection nozzle that are movable along the longitudinal direction of the lower portion of the vehicle to be cleaned, and moves in conjunction with the traveling movement of the car wash machine body.

この構成によると、下面洗浄装置がサイドブラシから離れた位置に設置されるので、洗車機やコンベア装置の設置レイアウトに影響を受けずに配設可能となる。また、下面洗浄装置は洗車機本体に連動して移動するので、洗車機本体側で検知する被洗浄車両の前端部と後端部との間の被洗浄車両の下面部を確実に洗浄することができる。すなわち、被洗浄車両の先端位置と後端位置との間を、下面洗浄装置の作動領域とすることができ、被洗浄車両を外れた領域では洗浄水を噴射せず、洗い残しを残さないで車両の下面全体を確実に洗浄可能となる。   According to this configuration, since the lower surface cleaning device is installed at a position away from the side brush, it can be arranged without being affected by the installation layout of the car wash machine or the conveyor device. In addition, since the lower surface cleaning device moves in conjunction with the car wash machine body, the lower surface part of the vehicle to be cleaned between the front end portion and the rear end portion of the vehicle to be cleaned, which is detected on the car wash machine side, can be surely cleaned. Can do. That is, the area between the front end position and the rear end position of the vehicle to be cleaned can be used as the operation area of the lower surface cleaning device, and the cleaning water is not jetted in the area outside the vehicle to be cleaned, so that no washing remains. The entire lower surface of the vehicle can be reliably cleaned.

また本発明は、上記構成の洗車機において、前記洗車機本体の前記サイドブラシ設置部位と前後方向に離れた位置に被洗浄車両を検知するエリアセンサを設け、前記下面洗浄装置は、前記サイドブラシと前記エリアセンサの間に設置されていることを特徴としている。この構成によると、サイドブラシが被洗浄車両の先端に当接して検知される先端位置と、エリアセンサが検知する被洗浄車両の後端位置との間を、下面洗浄装置の作動領域とすることで、被洗浄車両の下面以外では洗浄水を噴射せず、洗い残しを残さないで車両の下面全体を洗浄可能となる。   According to the present invention, in the car wash machine configured as described above, an area sensor that detects a vehicle to be cleaned is provided at a position away from the side brush installation part of the car wash machine body in the front-rear direction. And the area sensor. According to this configuration, the operation region of the lower surface cleaning device is defined between the front end position detected when the side brush contacts the front end of the vehicle to be cleaned and the rear end position of the vehicle to be cleaned detected by the area sensor. Thus, it is possible to clean the entire lower surface of the vehicle without spraying the cleaning water except for the lower surface of the vehicle to be cleaned, and leaving no washing residue.

また本発明は、上記構成の洗車機において、前記下面洗浄装置は、前記待機位置から被洗浄車両の先端部に移動する戻り工程と、当該先端部から被洗浄車両の後端部に移動する前進工程とを備え、該前進工程中に前記下面噴射ノズルから洗浄水を噴射して洗浄動作を行うことを特徴としている。この構成によると、被洗浄車両の先端部から後端部まで確実に洗浄することができて洗い残しを生じない。   According to the present invention, in the car wash machine having the above-described configuration, the lower surface cleaning device moves back from the standby position to the front end of the vehicle to be cleaned, and moves forward from the front end to the rear end of the vehicle to be cleaned. And a cleaning operation is performed by injecting cleaning water from the lower surface injection nozzle during the advancement step. According to this structure, it can wash | clean reliably from the front-end | tip part of a to-be-cleaned vehicle to a rear-end part, and does not produce unwashed residue.

また本発明は、上記構成の洗車機において、前記戻り工程中に、前記下面噴射ノズルから洗浄水を噴射して洗浄動作を行うことを特徴としている。この構成によると、サイドブラシが被洗浄車両の先端に当接して先端位置が検出されたときに、下面洗浄装置が車体の内側に待機していても、この待機位置から被洗浄車両の先端部に向かう戻り工程中においても下面洗浄を行うことで、待機位置から被洗浄車両の先端部までの領域をさらに確実に洗浄することができる。   According to the present invention, in the car wash machine configured as described above, a cleaning operation is performed by injecting cleaning water from the lower surface injection nozzle during the return step. According to this configuration, even if the lower surface cleaning device is waiting inside the vehicle body when the side brush is in contact with the front end of the vehicle to be cleaned and the front end position is detected, the front end portion of the vehicle to be cleaned from this standby position. By performing the bottom surface cleaning even during the return process toward the vehicle, the region from the standby position to the tip of the vehicle to be cleaned can be more reliably cleaned.

また本発明は、上記構成の洗車機において、待機位置にある前記下面洗浄装置と前記サイドブラシとの間隔である第一離間距離と、前記下面洗浄装置と前記エリアセンサとの間隔である第二離間距離と、が予め記憶されており、前記第一離間距離に応じて前記下面洗浄装置の先端洗浄開始位置が規定され、前記第二離間距離に応じて前記下面洗浄装置の後端洗浄停止位置が規定されることを特徴としている。この構成によると、洗車機本体に設けるサイドブラシとエリアセンサとにより検知される被洗浄車両の前後端の間の車両下部を確実に洗浄することができる。   According to the present invention, in the car wash machine having the above-described configuration, a first separation distance that is an interval between the lower surface cleaning device and the side brush in a standby position, and a second interval that is an interval between the lower surface cleaning device and the area sensor. The separation distance is stored in advance, the front edge cleaning start position of the lower surface cleaning apparatus is defined according to the first separation distance, and the rear edge cleaning stop position of the lower surface cleaning apparatus according to the second separation distance Is specified. According to this configuration, the lower part of the vehicle between the front and rear ends of the vehicle to be cleaned, which is detected by the side brush provided in the car wash machine main body and the area sensor, can be reliably cleaned.

本発明によれば、サイドブラシ設置部位と前後方向に所定距離離れた位置に下面洗浄装置の待機位置を設定し、洗車機本体の走行移動に連動して移動する構成としたので、洗車機やコンベア装置の設置レイアウトに影響を受けずに配設可能であり、洗車機本体側で検知する被洗浄車両の前端部と後端部との間の被洗浄車両の下面部を洗浄することができる。そのために、被洗浄車両を外れた領域では洗浄水を噴射せず、洗い残しを残さないで車両の下面全体を確実に洗浄可能な下面洗浄装置を備える洗車機を得ることができる。   According to the present invention, the standby position of the lower surface cleaning device is set at a position that is a predetermined distance away from the side brush installation site in the front-rear direction, and is configured to move in conjunction with the traveling movement of the car wash machine body. It can be arranged without being affected by the installation layout of the conveyor device, and can clean the lower surface portion of the vehicle to be cleaned between the front end portion and the rear end portion of the vehicle to be cleaned, which is detected on the car wash machine main body side. . Therefore, it is possible to obtain a car washer having a lower surface cleaning device that can reliably clean the entire lower surface of the vehicle without spraying cleaning water in an area outside the vehicle to be cleaned and leaving no unwashed residue.

本実施形態の洗車機WAは、洗浄手段と乾燥手段を備え、洗車機本体と被洗浄車両とを前後方向に相対移動させながら、被洗浄車両の洗車を行う洗車機であって、先に説明した図9に示す洗車機WBと同様な構成とされている。ただし、被洗浄車両の下面を洗浄する下面洗浄装置を有する点が異なる。そのために、図8に示すように、車輪3を介してレール2上に沿って走行移動する門型の洗車機本体1の左右一対のレール2の中間に、下面洗浄装置WCを配設している。   The car wash machine WA of the present embodiment includes a washing means and a drying means, and is a car wash machine for washing a vehicle to be washed while moving the car wash machine body and the vehicle to be washed relative to each other in the front-rear direction. It is set as the structure similar to the car wash machine WB shown in FIG. However, the difference is that it has a lower surface cleaning device for cleaning the lower surface of the vehicle to be cleaned. For this purpose, as shown in FIG. 8, a bottom surface cleaning device WC is disposed between the pair of left and right rails 2 of the gate-type car wash machine body 1 that travels along the rails 2 via the wheels 3. Yes.

また、前述した車高検知センサ8に替えて、もしくは、車高検知センサ8に加えて透過式光電センサからなる車形検出センサ(エリアセンサ)を用いることもできる。この場合には、洗車機本体1の一方の側部の上下方向に投光器を併設し、これらの投光器に対向する他方の側部の上下方向に受光器を併設することで、洗浄位置に進入してくる被洗浄車両の車形を検知して、その先端部と後端部およびボンネット高さを検知する。   Further, instead of the vehicle height detection sensor 8 described above, or in addition to the vehicle height detection sensor 8, a vehicle shape detection sensor (area sensor) including a transmission type photoelectric sensor may be used. In this case, a projector is provided in the vertical direction on one side of the car wash machine main body 1, and a light receiver is provided in the vertical direction on the other side opposite to these projectors, thereby entering the cleaning position. The vehicle shape of the vehicle to be cleaned is detected, and the front end portion, rear end portion, and bonnet height are detected.

下面洗浄装置WCは、走行レール32上を走行する下面洗浄台車30を有する。また、下面洗浄台車30の上面には、被洗浄車両の下面に向けて洗浄水を噴射する洗浄水噴射ノズル31(図6参照)が複数(例えば、図6に示すように3個)設けられている。   The lower surface cleaning device WC includes a lower surface cleaning cart 30 that travels on the traveling rail 32. In addition, a plurality (for example, three as shown in FIG. 6) of cleaning water injection nozzles 31 (see FIG. 6) for injecting cleaning water toward the lower surface of the vehicle to be cleaned are provided on the upper surface of the lower surface cleaning carriage 30. ing.

また、洗車機本体1と連動して移動する構成として、サイドブラシ5を用いて被洗浄車両CAの側面を洗車中に、下面洗浄装置WCを被洗浄車両CAの下面に沿って移動させながら、洗浄水噴射ノズル31から洗浄水を噴射して、被洗浄車両の下面を洗浄することができる。   In addition, as a configuration that moves in conjunction with the car wash machine main body 1, while washing the side surface of the vehicle CA to be cleaned using the side brush 5, while moving the lower surface cleaning device WC along the lower surface of the vehicle CA to be cleaned, Cleaning water can be sprayed from the cleaning water spray nozzle 31 to clean the lower surface of the vehicle to be cleaned.

下面洗浄装置WCは、例えば図6に示す第一実施形態のように、洗車機本体1が走行する左右一対のレール2、2間に設置される走行レール32、32と、この上を走行自在に配設される走行台車30を有する。   The lower surface cleaning apparatus WC, for example, as in the first embodiment shown in FIG. 6, can travel on the traveling rails 32, 32 installed between the pair of left and right rails 2, 2 on which the car wash machine body 1 travels. A traveling carriage 30 is provided.

走行台車30は、台車本体に駆動源を設けた自走式の走行台車でも、別途設ける駆動源により走行移動する構成であってもよく特に限定されるものではない。また、外部に設けるタンクから配管を介して洗浄水を供給する構成としている。配管は、例えばケーブルベア方式に湾曲自在に変位するように配設される配管を用いて、往復走行移動する走行台車に洗浄水を安定して供給する。   The traveling carriage 30 may be a self-propelled traveling carriage provided with a drive source in the carriage body, or may be configured to travel and move with a separately provided drive source, and is not particularly limited. In addition, the cleaning water is supplied from a tank provided outside through a pipe. The piping stably supplies cleaning water to a traveling carriage that reciprocally moves using piping that is disposed so as to be able to bend in a cable bear system, for example.

洗車工程の開始は、洗車を望むユーザが所定の洗車モードをリモートパネル7Aに設定し、被洗浄車両CAをレール2、2間の所定の洗車位置に停車した後、開始される。まず、被洗浄車両CAが所定の洗車位置に到達したことが検知されると、待機位置にある洗車機本体1が被洗浄車両CAの方に前進移動して所定の洗車工程を実行する。もしくは、洗車を望むユーザが被洗浄車両CAをレール2、2間の所定の洗車位置に停車した後、所定の洗車モードを洗車機本体に設置された操作パネル7に設定し、洗車工程を開始させる構成としてもよい。   The start of the car wash process is started after a user who wishes to wash the car sets a predetermined car wash mode on the remote panel 7A and stops the vehicle to be cleaned CA at a predetermined car wash position between the rails 2 and 2. First, when it is detected that the vehicle to be cleaned CA has reached a predetermined car wash position, the car wash machine main body 1 in the standby position moves forward toward the car to be cleaned CA and executes a predetermined car wash process. Alternatively, after a user wishing to wash the car stops the car to be washed CA at a predetermined car wash position between the rails 2 and 2, a predetermined car wash mode is set on the operation panel 7 installed in the car wash machine body, and the car wash process is started. A configuration may be adopted.

洗車機本体1は、例えば図に示すような投光器9Aと受光器9Bを備えるエリアセンサ9を備えており、洗車機本体1を走行移動させたときの走行距離とこのエリアセンサ9が検知する被洗浄車両CAの先端部位置と後端部位置とにより、車両長さや車体形状を認識する。また、左右一対のサイドブラシ5、5を閉状態として被洗浄車両CAの先端部に当接させた位置から洗車を開始する。   The car wash machine main body 1 includes an area sensor 9 having a projector 9A and a light receiver 9B as shown in the figure, for example, and the distance traveled when the car wash machine main body 1 travels and the object detected by the area sensor 9 are detected. The vehicle length and the vehicle body shape are recognized from the front end position and the rear end position of the cleaning vehicle CA. Further, the car wash is started from the position where the pair of left and right side brushes 5 and 5 are closed and brought into contact with the tip of the vehicle to be cleaned CA.

左右一対のサイドブラシ5、5は、被洗浄車両CAの車幅方向の開閉自在であり、また、それぞれのブラシ軸を揺動支持部を介して回転自在に吊り下げられた構成であり、被洗浄車両CAの傾斜した側面部に対応して傾斜した状態で当接して洗車を行う。また、閉状態で被洗浄車両CAの前面に当接した状態で回転しながら開いていくことで、被洗浄車両CAの前面部を洗車する。前面部を洗車した後、車体の側面に回り込むと、この車体の側面部に当接した状態を維持したまま洗車機本体1と共に前進移動して車体の側面部を洗車する。また、側面部の洗車が終了した後は、洗車機本体1の走行を停止し、左右一対のサイドブラシ5、5を開状態から徐々に閉じていって側面部から回り込んで後面部を洗車する。   The pair of left and right side brushes 5 and 5 are openable and closable in the vehicle width direction of the vehicle CA to be cleaned, and each brush shaft is rotatably suspended via a swing support portion. Car wash is performed by abutting in an inclined state corresponding to the inclined side surface of the cleaning vehicle CA. Further, the front portion of the vehicle to be cleaned CA is washed by rotating and opening while in contact with the front surface of the vehicle CA to be cleaned. After washing the front part, when it goes around the side surface of the vehicle body, it moves forward together with the car wash machine main body 1 while maintaining the state in contact with the side surface part of the vehicle body to wash the side surface part of the vehicle body. In addition, after the car wash of the side surface is finished, the car wash machine 1 stops traveling, and the pair of left and right side brushes 5 and 5 are gradually closed from the open state and turn around from the side surface to wash the rear surface. To do.

このように、図6に示す第一実施形態では、被洗浄車両CAが所定の洗車位置に停止した状態で洗車機本体1を往復移動して洗車している。これとは別に、コンベア装置を用いて被洗浄車両CAを往復移動可能な構成として、長さの短い設置スペースであっても洗車機本体1との相対移動を可能として洗車を行う方式も採用されている。この実施形態の一例について図7を用いて説明する。   As described above, in the first embodiment shown in FIG. 6, the car wash machine main body 1 is moved back and forth while the car CA to be cleaned is stopped at a predetermined car wash position. In addition to this, as a configuration capable of reciprocating the vehicle to be cleaned CA using a conveyor device, a method of washing the vehicle so that it can be moved relative to the car wash machine body 1 even in a short installation space is adopted. ing. An example of this embodiment will be described with reference to FIG.

図7に示す第二実施形態の洗車機WAaは、左右一対のレール2、2間に被洗浄車両CAを搬送するコンベア装置40を設けた例である。このコンベア装置40は、左右のタイヤを載置する左右一対のコンベアを有している。このような構成の洗車機WAaでは、コンベア上に停車した被洗浄車両CAを、コンベア装置40により往復移動させることができるので、狭い設置スペースであっても、洗車機本体1を用いて一連の洗車工程が実行可能となって好ましい。このコンベア装置40は、駆動シャフト41と従動シャフト42を備え、駆動モータ(不図示)を介して駆動シャフト41を回転駆動して、コンベア上に停車した被洗浄車両CAを移動して洗車を行う。すなわち、被洗浄車両CAを往復移動して、洗車機本体1と被洗浄車両CAとを相対移動させている。   The car wash machine WAa of the second embodiment shown in FIG. 7 is an example in which a conveyor device 40 that conveys the vehicle to be cleaned CA is provided between the pair of left and right rails 2 and 2. The conveyor device 40 has a pair of left and right conveyors on which left and right tires are placed. In the car wash machine WAa having such a configuration, the car to be washed CA stopped on the conveyor can be reciprocated by the conveyor device 40, and therefore, even in a narrow installation space, the car wash machine main body 1 is used for a series of operations. It is preferable because the car washing process can be executed. The conveyor device 40 includes a drive shaft 41 and a driven shaft 42, and rotates the drive shaft 41 via a drive motor (not shown) to move the vehicle to be cleaned CA stopped on the conveyor to perform car washing. . That is, the vehicle to be cleaned CA is reciprocated to relatively move the car wash machine body 1 and the vehicle to be cleaned CA.

この第二実施形態においては、下面洗浄装置WCの設置位置は左右のコンベア間に限定される。そのために、左右のコンベア間に走行レール32、32を設置し、この上を走行台車30が走行移動する構成としている。すなわち、コンベア装置40の左右のコンベア間が下面洗浄装置WCの可動領域となる。   In the second embodiment, the installation position of the lower surface cleaning device WC is limited between the left and right conveyors. For this purpose, traveling rails 32, 32 are installed between the left and right conveyors, and the traveling carriage 30 travels on this. That is, the space between the left and right conveyors of the conveyor device 40 is a movable region of the lower surface cleaning device WC.

また、可動領域の長手方向の限界位置において、駆動シャフト41や従動シャフト42と干渉しないことが好ましいので、この両シャフト間の内部領域を下面洗浄装置WCの可動領域とする。すなわち、被洗浄車両CAを搬送するコンベア装置40を設けた場合は、左右のコンベア間で且つ前後のシャフト間の領域に下面洗浄装置WCを設置し、この領域を下面洗浄装置WCの可動領域に設定する。   Further, since it is preferable not to interfere with the drive shaft 41 and the driven shaft 42 at the limit position in the longitudinal direction of the movable region, the inner region between both shafts is set as the movable region of the lower surface cleaning device WC. That is, when the conveyor device 40 for transporting the vehicle to be cleaned CA is provided, the lower surface cleaning device WC is installed in the region between the left and right conveyors and between the front and rear shafts, and this region is made a movable region of the lower surface cleaning device WC. Set.

本実施形態の下面洗浄装置WCは、このように設置された構成であっても、被洗浄車両CAの下面全域を確実に洗浄可能にするものであって、洗車機やコンベア装置の設置レイアウトに影響を受けずに配設可能な構成とされるものである。   Even if the lower surface cleaning apparatus WC of the present embodiment is configured as described above, the entire lower surface of the vehicle CA to be cleaned can be reliably cleaned, and the installation layout of the car wash machine and the conveyor device can be used. It can be arranged without being affected.

次に、下面洗浄装置WCの構成と洗浄動作について、図1から図5を用いて説明する。また、ここで説明する洗車機は、コンベア装置40を用いずに、洗車機本体1が走行移動して洗車を行うタイプの洗車機WAに基づいている。   Next, the configuration and cleaning operation of the lower surface cleaning apparatus WC will be described with reference to FIGS. The car wash machine described here is based on a car wash machine WA of the type in which the car wash machine body 1 travels and performs car wash without using the conveyor device 40.

洗車を希望するユーザは、所定の洗車モードに設定した後、図1に示すように、所定の待機位置に停止している洗車機本体1Aに向かって被洗浄車両CAを図中の矢印D1に示す方向に移動し、所定の洗車位置で停止する。   The user who wishes to wash the vehicle sets the vehicle to be washed CA toward the car wash machine main body 1A stopped at the predetermined standby position as shown in FIG. It moves in the direction shown and stops at a predetermined car wash position.

洗車機本体1Aには前述したように、エリアセンサ9とサイドブラシ5が設けられている。そのために、車両がエリアセンサ9の検知部を通過して所定位置に停車すると、このエリアセンサ9を介して被洗浄車両CAが洗車位置に停車したことが検知される。   As described above, the car wash machine main body 1 </ b> A is provided with the area sensor 9 and the side brush 5. Therefore, when the vehicle passes through the detection unit of the area sensor 9 and stops at a predetermined position, it is detected via the area sensor 9 that the vehicle to be cleaned CA has stopped at the car wash position.

また、洗車本体1Aに設けられているエリアセンサ9とサイドブラシ5の水平方向(前後方向)の中間に下面洗浄装置WCが待機している。すなわち、サイドブラシ5から前後方向に第一離間距離L1離れた位置に下面洗浄装置WCが待機している。また、この待機位置は、エリアセンサ9から第二離間距離L2離れた位置であって、エリアセンサ9とサイドブラシ5とは距離L(L1+L2)離れた構成とされる。   Further, the lower surface cleaning device WC stands by in the middle of the horizontal direction (front-rear direction) of the area sensor 9 and the side brush 5 provided in the car wash main body 1A. That is, the lower surface cleaning device WC stands by at a position away from the side brush 5 in the front-rear direction by the first separation distance L1. The standby position is a position away from the area sensor 9 by the second separation distance L2, and the area sensor 9 and the side brush 5 are separated from each other by a distance L (L1 + L2).

被洗浄車両CAが洗車位置に停車した後、洗車工程が実行される。先ず、図2に示すように、洗車機本体が図中の矢印D2に示す方向に移動して、サイドブラシ5が被洗浄車両CAの先端部に当接した位置で停止する。すわなち、この位置で停止した洗車機本体1Bは、サイドブラシ5を用いて被洗浄車両CAの前面を洗車可能な状態となる。   After the vehicle to be cleaned CA stops at the car wash position, the car wash process is executed. First, as shown in FIG. 2, the car washer main body is moved in the direction indicated by the arrow D2 in the drawing, and the side brush 5 stops at a position where it abuts against the tip of the vehicle to be cleaned CA. That is, the car wash machine main body 1 </ b> B stopped at this position is in a state in which the front surface of the vehicle to be cleaned CA can be washed using the side brush 5.

サイドブラシ5が被洗浄車両CAの先端部に当接したことを検知する方法は従来公知の方法を用いる。例えば、揺動支持部51を介して揺動自在、また、回転自在に吊り下げ構成されたサイドブラシ5のブラシ軸52の傾きを検知するセンサを用いて検知することができる。   A conventionally known method is used as a method for detecting that the side brush 5 has come into contact with the tip of the vehicle CA to be cleaned. For example, it can be detected using a sensor that detects the inclination of the brush shaft 52 of the side brush 5 that is configured to be swingable via the swing support portion 51 and to be rotatable.

サイドブラシ5が被洗浄車両5の先端部に当接した状態でサイドブラシ5を回転させて、被洗浄車両CAの前面を洗車する。このときに、下面洗浄装置WCは、車両下部に位置しているので、洗浄水噴射ノズルから洗浄水を噴射して被洗浄車両の下面を洗浄する。   The side brush 5 is rotated in a state where the side brush 5 is in contact with the tip of the vehicle 5 to be cleaned, and the front surface of the vehicle CA to be cleaned is washed. At this time, since the lower surface cleaning device WC is located at the lower part of the vehicle, the lower surface of the vehicle to be cleaned is cleaned by injecting cleaning water from the cleaning water injection nozzle.

左右一対のサイドブラシ5を回転させながら閉状態から徐々に開いていき、被洗浄車両CAの前面を洗車する。また、車両の全幅を洗車すると車両の側面に至る際に、ブラシ軸52の傾きの変化によって、前面部の洗車完了を検知する。その後、サイドブラシ5の回転を停止し、図3に示すように矢印D3に示す方向に洗車機本体を後進移動する。   The pair of left and right side brushes 5 are gradually opened from the closed state while rotating, and the front surface of the vehicle CA to be cleaned is washed. Further, when the entire width of the vehicle is washed, when the vehicle reaches the side of the vehicle, the completion of the washing of the front portion is detected by the change in the inclination of the brush shaft 52. Thereafter, the rotation of the side brush 5 is stopped, and the car wash machine body is moved backward in the direction indicated by the arrow D3 as shown in FIG.

すなわち、下面洗浄装置WCを被洗浄車両CAの先端部に向けて移動させる。この後進移動中に洗浄水噴射ノズルから洗浄水を噴射して、先端部に至る被洗浄車両の下面を洗浄することができる。また、この際に、第一離間距離L1に相当する距離移動させる構成であれば、この移動中連続して噴射しても、被洗浄車両CAの下面以外では洗浄水を噴射しないので好ましい。   That is, the lower surface cleaning device WC is moved toward the tip of the vehicle to be cleaned CA. During this backward movement, the cleaning water can be sprayed from the cleaning water spray nozzle to clean the lower surface of the vehicle to be cleaned that reaches the tip. Further, at this time, it is preferable that the structure is moved by a distance corresponding to the first separation distance L1, because even if sprayed continuously during the movement, cleaning water is not sprayed except at the lower surface of the vehicle CA to be cleaned.

また、この後進移動が、洗車機本体を当初の待機位置まで戻す工程であっても、洗浄水噴射ノズルからの噴射を、第一離間距離L1に相当する距離移動させる間に限定することで、被洗浄車両CAを外れた領域、すなわち被洗浄車両CAの下面以外では洗浄水を噴射しない構成とすることができる。   Further, even if this backward movement is a step of returning the car wash machine main body to the initial standby position, by limiting the injection from the washing water injection nozzle while moving the distance corresponding to the first separation distance L1, It is possible to adopt a configuration in which the cleaning water is not jetted in a region outside the vehicle to be cleaned CA, that is, other than the lower surface of the vehicle CA to be cleaned.

次に、下面洗浄装置WCが被洗浄車両CAの先端部を洗浄する位置にあるときの洗車機本体1Cを図4に示す矢印D4方向に前進移動させ、下面洗浄装置WCが被洗浄車両CAの後端部を洗浄する位置にある洗車機本体1Dまで洗浄動作を持続して、被洗浄車両CAの下面全体を洗浄する。   Next, the lower surface cleaning device WC moves forward in the direction of the arrow D4 shown in FIG. 4 when the lower surface cleaning device WC is in a position to clean the tip of the cleaned vehicle CA, and the lower surface cleaning device WC The cleaning operation is continued up to the car wash machine main body 1D at the position for cleaning the rear end portion, and the entire lower surface of the vehicle CA to be cleaned is cleaned.

洗車機本体1Dの位置では、被洗浄車両CAの後端部を洗浄している下面洗浄装置WCの位置はエリアセンサ9から第二離間距離L2離れた位置である。すなわち、エリアセンサ9を介して被洗浄車両CAの後端部位置を検出した後、洗車機本体1を距離L2前進移動させるまで、下面洗浄装置WCを用いて被洗浄車両CAの後端部を洗浄する構成とすれば、被洗浄車両CAの下面部のみを正確に洗浄し、被洗浄車両CAを外れた領域、すなわち被洗浄車両CAの下面以外では洗浄水を噴射しない。   At the position of the car wash machine main body 1D, the position of the lower surface cleaning device WC that is cleaning the rear end of the vehicle to be cleaned CA is a position away from the area sensor 9 by the second separation distance L2. That is, after detecting the position of the rear end portion of the vehicle CA to be cleaned via the area sensor 9, the rear end portion of the vehicle CA to be cleaned is moved using the lower surface cleaning device WC until the car wash machine body 1 is moved forward by the distance L2. If it is set as the structure wash | cleaned, only the lower surface part of the to-be-cleaned vehicle CA will be wash | cleaned correctly, and cleaning water will not be injected except the area | region which removed the to-be-cleaned vehicle CA, ie, the lower surface of the to-be-cleaned vehicle CA.

また、洗車機本体1をさらに前進移動して、サイドブラシ5を用いて被洗浄車両CAの側面、および後面を洗車する動作を続行する。   Further, the car wash machine main body 1 is further moved forward, and the operation of washing the side surface and the rear surface of the vehicle CA to be cleaned using the side brush 5 is continued.

次に、図5を用いて下面洗浄装置WCを用いて被洗浄車両CAの下部を洗浄する領域についてさらに説明する。   Next, the area | region which wash | cleans the lower part of the to-be-cleaned vehicle CA using the lower surface washing | cleaning apparatus WC is further demonstrated using FIG.

下面洗浄装置WCは洗車機本体1に連動して往復移動する構成としているので、洗車機本体が移動している際の、下面洗浄装置WCが被洗浄車両CAの先端部に位置する洗車機本体1Cから、下面洗浄装置WCが被洗浄車両CAの後端部に位置する洗車機本体1Dまでの間、洗浄水を噴射して被洗浄車両CAの下面を洗浄する。   Since the lower surface cleaning apparatus WC is configured to reciprocate in conjunction with the car wash machine main body 1, the lower surface cleaning apparatus WC is located at the tip of the vehicle to be cleaned CA when the car wash machine main body is moving. From 1C to the car wash machine main body 1D located at the rear end of the vehicle to be cleaned CA, the lower surface cleaning device WC injects cleaning water to clean the lower surface of the vehicle CA to be cleaned.

また、下面洗浄装置WCの走行台車30は、被洗浄車両CAの先端部を洗浄する位置にある走行台車30Aとサイドブラシ5との距離が第一離間距離L1離れており、被洗浄車両CAの後端部を洗浄する位置にある走行台車30Bとエリアセンサ9との距離が第二離間距離L2離れている。   Further, in the traveling carriage 30 of the lower surface cleaning apparatus WC, the distance between the traveling carriage 30A and the side brush 5 at the position for cleaning the front end portion of the vehicle to be cleaned CA is separated from the first separation distance L1. The distance between the traveling carriage 30B at the position for cleaning the rear end portion and the area sensor 9 is separated from the second separation distance L2.

そのために、サイドブラシ5が被洗浄車両CAの先端に当接した状態から距離L1だけ洗車機本体を後進させた位置から、エリアセンサ9が被洗浄車両CAの後端を検出した状態から距離L2だけ洗車機本体を前進させた位置までの間が、下面洗浄装置WCの洗浄領域となる。   Therefore, the distance L2 from the state where the area sensor 9 detects the rear end of the vehicle CA to be cleaned from the position where the car wash machine main body is moved backward by the distance L1 from the state in which the side brush 5 is in contact with the tip of the vehicle CA to be cleaned. The area up to the position where the main body of the car washer is advanced is the cleaning area of the lower surface cleaning device WC.

すなわち、下面洗浄装置WCとサイドブラシ5との前後方向の間隔である第一離間距離L1と、下面洗浄装置WCとエリアセンサ9との前後方向の間隔である第二離間距離L2と、が予め記憶されており、第一離間距離L1に応じて下面洗浄装置WCの先端洗浄開始位置が規定され、第二離間距離L2に応じて下面洗浄装置WCの後端洗浄停止位置が規定される。   That is, the first separation distance L1 that is the distance in the front-rear direction between the lower surface cleaning device WC and the side brush 5 and the second separation distance L2 that is the distance in the front-rear direction between the lower surface cleaning device WC and the area sensor 9 are preliminarily set. The front end cleaning start position of the lower surface cleaning device WC is defined according to the first separation distance L1, and the rear end cleaning stop position of the lower surface cleaning device WC is defined according to the second separation distance L2.

上記の構成であれば、洗車機本体やコンベア装置を設置した後に、下部洗浄装置WCを新たに設置する場合でも、採用された第一離間距離L1と第二離間距離L2とを新たに設定して、この下部洗浄装置WCを洗車機本体1に連動して駆動することができ、洗車機本体1に設けるサイドブラシ5とエリアセンサ9とにより検知される被洗浄車両の前後端の間の車両下部を確実に洗浄することができる。   If it is said structure, even when installing the lower washing | cleaning apparatus WC newly after installing a car wash machine main body and a conveyor apparatus, the employ | adopted 1st separation distance L1 and 2nd separation distance L2 are newly set. Thus, the lower washing apparatus WC can be driven in conjunction with the car wash machine body 1, and the vehicle between the front and rear ends of the vehicle to be washed detected by the side brush 5 and the area sensor 9 provided in the car wash machine body 1. The lower part can be reliably cleaned.

以上、説明したように、本実施形態に係る洗車機WAは、被洗浄車両の下面を洗浄する下面洗浄装置を有する洗車機において、パルスセンサを備えていない簡単な構成であっても、洗車機本体やコンベア装置の設置レイアウトに影響を受けずに配設可能であり、被洗浄車両の下面以外では洗浄水を噴射せず、洗い残しを残さないで車両の下面全体を洗浄可能な洗車機となる。   As described above, the car wash machine WA according to the present embodiment is a car wash machine having a lower surface cleaning device for cleaning the lower surface of the vehicle to be cleaned, even if it has a simple configuration without a pulse sensor. A car washer that can be installed without being affected by the installation layout of the main body and conveyor device, and that can wash the entire bottom surface of the vehicle without spraying washing water and leaving no washing residue other than the bottom surface of the vehicle to be cleaned. Become.

また、下面洗浄装置は、待機位置から被洗浄車両の先端部に移動する戻り工程と、当該先端部から被洗浄車両の後端部に移動する前進工程とを備え、該前進工程中に下面噴射ノズルから洗浄水を噴射して洗浄動作を行うようにしているので、被洗浄車両の先端部から後端部まで確実に洗浄することができて洗い残しを生じない。   Further, the lower surface cleaning apparatus includes a return step for moving from the standby position to the front end portion of the vehicle to be cleaned and a forward step for moving from the front end portion to the rear end portion of the vehicle to be cleaned, and the lower surface injection is performed during the forward step. Since the cleaning operation is performed by injecting the cleaning water from the nozzle, it is possible to reliably clean from the front end portion to the rear end portion of the vehicle to be cleaned, and no unwashed residue is generated.

また、待機位置にある下面洗浄装置とサイドブラシとの前後方向(水平方向)の間隔である第一離間距離と、下面洗浄装置とエリアセンサとの前後方向の間隔である第二離間距離と、が予め記憶されており、第一離間距離に応じて下面洗浄装置の先端洗浄開始位置が規定され、第二離間距離に応じて下面洗浄装置の後端洗浄停止位置が規定されるようにしているので、洗車機本体に設けるサイドブラシとエリアセンサとにより検知される被洗浄車両の前後端の間の車両下部を確実に洗浄することができる。   Further, a first separation distance that is a distance in the front-rear direction (horizontal direction) between the lower surface cleaning device and the side brush at the standby position, and a second separation distance that is a distance in the front-rear direction between the lower surface cleaning device and the area sensor, Is stored in advance, the front end cleaning start position of the lower surface cleaning apparatus is defined according to the first separation distance, and the rear end cleaning stop position of the lower surface cleaning apparatus is defined according to the second separation distance. Therefore, the lower part of the vehicle between the front and rear ends of the vehicle to be cleaned, which is detected by the side brush and the area sensor provided in the car wash machine main body, can be reliably cleaned.

そのために、本発明に係る洗車機は、洗車機本体やコンベア装置の設置レイアウトに影響を受けずに配設可能な下面洗浄装置を用いて被洗浄車両の下部を洗浄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 required to wash the lower part of the vehicle to be washed using the lower surface washing device that can be arranged without being affected by the installation layout of the car wash machine body and the conveyor device.
