(Embodiment 1)
Embodiment 1 of the present invention will be described based on the drawings. 1 is a side view of a car washing apparatus 10 according to this embodiment, FIG. 2 is a top view of the same, and FIG. 3 is a front view of the same.

The car washing device 10 has a main body 11 standing upright on the ground G (laying surface). The main body 11 has a gate-shaped housing (frame) so as to straddle the vehicle C to be processed. For this reason, the body portion 11 has legs 12a and 12b that stand up from the ground G. As shown in FIG. Further, the body portion 11 has a beam portion 13 that extends over the leg portions 12a and 12b.

The car wash device 10 also includes rails 14 and wheels 15 and 16 . A pair of rails 14 are provided on the ground G so as to extend parallel to each other. A wheel 15 is provided on the front side of the bottom of each of the legs 12a and 12b. Wheels 16 are provided on the rear side of the bottom of each leg 12a, 12b. The main body 11 moves back and forth (reciprocates) on a pair of rails 14 via wheels 15 and 16 . In this embodiment, the wheels 15 are driving wheels and the wheels 16 are driven wheels.

The car wash apparatus 10 also includes a travel motor 17 and a travel encoder 18 . The running motor 17 is provided on each of the leg portions 12a and 12b of the body portion 11 so as to be connected to the wheel 15 from a position higher than the wheel 15 with respect to the ground G. As shown in FIG. The traveling motor 17 is configured to be reversible forward and backward, and moves (reciprocates) the main body 11 back and forth via wheels 15 (driving wheels). The travel encoder 18 is provided on one of the leg portions 12a and 12b of the body portion 11, and is connected to the output shaft of the travel motor 17 on one side thereof. A travel encoder 18 detects the travel position of the main body 11 on the rail 14 . That is, the travel encoder 18 detects the rotation direction of the travel motor 17, that is, the rotation direction of the wheels 15, and outputs a pulse signal for each unit angular rotation.

The car wash apparatus 10 also includes a front/rear switch 19 and a dock 20a and a dock 20b. The front/rear switch 19 is provided on the bottom of either leg 12a or 12b. The dock 20a is provided on one end side of one of the rails 14 (the front side in the front-rear direction of the main body 11), and the dock 20b is provided on the other end side (rear side in the front-rear direction) of the same rail. The forward/backward switch 19 switches between the docks 20a and 20b according to the movement of the main body 11, and detects the movement limit of the main body 11 between the docks 20a and 20b. Therefore, the main body 11 of the car wash device 10 can move within the movement limit so as to straddle the stopped vehicle C and pass in the vehicle length direction. The state (standby state) in which the car wash apparatus 10 waits for entry into the car is a state in which the front/rear switch 19 is switched to the dock 20b and the main body 11 is stopped.

In the washing process described later, the main body 11 is washed while straddling the vehicle C and reciprocating within the movement limit. Therefore, the vehicle C to be washed needs to advance between the rails 14 before starting the washing process, approach the main body part 11, and stop at a position where it does not come into contact with the main body part 11 during the washing process. In this embodiment, the range 21 shown in FIG. 3 is defined as the range in which the body portion 11 and the vehicle C do not contact each other. Vehicles that do not stop within range 21 cannot be washed, and substantially range 21 can be regarded as a washable range.

The washable range is a range in which the washing process can be completed without damaging the vehicle, and is determined from the structure and specifications of each car washing apparatus. If the car washing apparatus has a washing process emergency stop function based on the stop position of the vehicle, the washable range is the range in which the washing process can be completed without emergency stop. For example, in this embodiment, the boundary lines 23a, 23b, and 23c forming the range 21 are at the following positions.
23a: The position of the line connecting the element provided at the highest position in the height direction of the main body 11 among the light emitting and receiving elements provided in the vehicle detection unit 44 23b: From the leg 12b to the opening side of the main body 11 Position 23c of a line parallel to the leg 12b, which is assumed to be 20 cm away: Parallel to the leg 12a, which is assumed to be a position 20 cm away from the leg 12a toward the opening of the main body 11 position of a line

The light emitting part 22 provided in the car washing apparatus 10 is buried in the ground G on the front side of the main body part 11 at a position where it can emit light on the boundary lines 23 b and 23 c of the range 21 . The light emitting unit 22 is composed of a transmissive photoelectric sensor, and a light projecting element (not shown) faces the main body 11 side, and is provided so as to be capable of projecting light over a range including at least a range in which a light receiving unit 37 (to be described later) can be displaced. Since the light receiving portion 37 can receive the light projected from the light emitting portion 22 and can be displaced on the boundary lines 23b and 23c of the range 21, for example, when the vehicle C advances between the rails 14, the light projected from the light emitting portion 22 is detected. If none of the light-receiving units 37 detect it, it can be seen that the vehicle C is out of the range 21 and is moving toward either the left or right direction of the main body 11 .

The car washing device 10 includes a top brush 24 and a pair of side brushes 25 provided on the body portion 11 as a washing processing device. The top brush 24 (rotating brush) is accommodated in the opening upper part side (beam part 13 side) of the gate-shaped main body part 11 at the standby time. The top brush 24 moves up and down while rotating along with the movement of the main body 11 as a movable part, and can mainly brush the upper surface of the vehicle C. As shown in FIG. A pair of side brushes 25 (rotating brushes) are accommodated on the side of the opening of the gate-shaped main body 11 (on the sides of the legs 12a and 12b, respectively) during standby. The pair of side brushes 25 is a movable part that opens and closes (moves toward and away from each other) while rotating as the main body 11 moves, and can mainly brush the front, side, and rear surfaces of the vehicle C. . The opening and closing operations of the top brush 24 and the side brushes 25 with respect to the vehicle C are controlled along the shape of the vehicle C by a control unit 45, which will be described later.

The car washing apparatus 10 also includes a top spray 26 and a pair of side sprays 27 provided on the main body 11 as washing processing apparatuses. The top spray 26 is accommodated on the opening upper side (beam 13 side) of the gate-shaped main body 11 . The top spray 26 can mainly wash the upper surface of the vehicle C by injecting a cleaning liquid such as water from a plurality of injection nozzles (not shown) provided on a pipe as the main body 11 moves. A pair of side sprays 27 are housed on the side of the opening of the gate-shaped body 11 (on the sides of the legs 12a and 12b, respectively). The pair of side sprays 27 can mainly wash the side surfaces of the vehicle C by injecting a cleaning liquid such as water from a plurality of injection nozzles (not shown) provided on the pipes as the main body 11 moves.

The car washing apparatus 10 also includes a top nozzle 28 (blower nozzle) provided on the main body 11 as a washing processing apparatus. The top nozzle 28 is composed of a substantially cylindrical nozzle body 71 and a support body 72 that supports the nozzle body 71 . In the cleaning process, the top nozzle 28 moves up and down while blowing air as the main body 11 moves, and can mainly dry the upper surface of the vehicle C. As shown in FIG. An elevating device for elevating the top nozzle 28 will be described with reference to FIG. The top nozzle 28 is supported at both ends by a carrier 29, and is vertically movable within the range of guide rails 30 formed on the legs 12a and 12b of the main body 11 as movement limits. The carrier 29 includes a chain 31 that endlessly connects the upper end and the lower end, sprockets 32a and 32b around which the chain 31 is wound, and a rotary shaft 33 that connects the sprockets 32a on each side. It is raised and lowered by forward and reverse rotation. An elevation encoder 35 is connected to the sprocket 32a on the leg 12a side, and the elevation position of the top nozzle 28 on the guide rail 30 can be detected. Limit switches 36 are provided at the upper and lower ends of the guide rail 30 on the side of the leg 12a to detect that the top nozzle 28 is at the movement limit position. The top nozzle 28 is held at the upper end of the guide rail 30 in the standby state, and is accommodated in the opening upper side (beam 13 side) of the gate-shaped main body 11 .

The top nozzle 28 further has a light receiving portion 37 . The light receiving portion 37 is provided on an extension line of the boundary lines 23 b and 23 c of the range 21 that is the washable range of the body portion 11 . A light receiving element (not shown) is provided so as to face the light emitting unit 22 so that the light receiving unit 37 can receive light projected from the light emitting unit 22 when the vehicle C enters. Therefore, if the light receiving portion 37 does not detect the light emitted from the light emitting portion 22 while the vehicle C is traveling between the rails 14, the vehicle C leaves the range 21 and moves toward either the left or right direction of the main body portion 11. It can be seen that

Further, as a washing processing device, the car washing device 10 includes a pair of side nozzles 38 (blower nozzles) fixedly provided on each of the leg portions 12 a and 12 b of the body portion 11 . The pair of side nozzles 38 can blow air as the main body 11 moves to dry mainly the side surfaces of the vehicle C in the cleaning process.

The car wash device 10 also includes an alarm unit 39 (not shown) provided in the main body 11 . The alarm unit 39 has a speaker and outputs sound based on a signal from the control unit 45, which will be described later. More specifically, the user who drives the vehicle C and the people around the car wash apparatus 10 are guided to enter the vehicle and alerted when the main body 11 runs.

The car wash apparatus 10 also includes a vehicle stop detection section 41 below and in front of the leg sections 12 a and 12 b of the body section 11 . The vehicle stop detection unit 41 is composed of a transmissive photoelectric sensor having a pair of light emitting element 42 and light receiving element 43 . The light-emitting element 42 is arranged to face the corresponding light-receiving element 43 at the same height, forming a horizontal optical axis therebetween. The optical axis is formed at a place (regular stop position) at which the vehicle C should stop when receiving the cleaning treatment from the cleaning device 10 . That is, by knowing the light passing/light blocking state, it is possible to detect whether or not the vehicle C traveling between the rails 14 has reached the normal stop position.

The car wash apparatus 10 also includes a vehicle detection unit 44 provided in the main body 11 and detecting the vehicle C over time as the main body 11 moves. The vehicle detection portion 44 is provided on the front side of the main body portion 11 so as to extend in the standing direction of the main body portion 11 (the vehicle height direction of the vehicle C). As the vehicle detection unit 44, a known configuration is adopted in which a plurality of transmissive photoelectric sensors each having a pair of a light emitting element and a light receiving element are provided, and the vehicle C is detected by knowing the light passing/light blocking state of each sensor. .

The car wash apparatus 10 also includes a control unit 45 (for example, a semiconductor device or an electronic substrate on which it is mounted), as shown in FIG. The control unit 45 is provided in the main unit 11, and includes the travel encoder 18, the front/rear switch 19, the vehicle stop detection unit 41, the vehicle detection unit 44, the light emitting unit 22, the light receiving unit 37, the alarm unit 39, the operation panel 46, and the driving device. 47, and according to the processing course accepted by the operation panel 46, a pre-programmed sequence (means) is executed. The operation panel 46 is a panel that enables basic operations such as starting/stopping the car wash of the car wash apparatus 10 and selecting the car wash processing course. The operation panel 46 may be provided standing up from the ground G separately from the main body 11 or may be provided on either side of the legs 12 a and 12 b of the main body 11 .

The control unit 45 also has an alarm means 60 , a travel detection means 48 , a vehicle detection means 49 , a data storage means 50 , a data storage means 51 , and a processing means 52 . The notification means 60 can output an audio signal to the notification section 39 based on the light passing/blocking state of the light receiving section 37 . The travel detection means 48 can detect the travel position (movement position) of the main body 11 from the pulse signal of the travel encoder 18 . The vehicle detection means 49 can detect the shape of the vehicle C by operating the vehicle detection section 44 each time the vehicle moves a unit distance, triggered by the pulse signal of the traveling encoder 18 . The data storage means 50 can create vehicle shape data from the detection results of the traveling detection means 48 and the vehicle detection means 49 . The data storage means 51 can store vehicle shape data. The processing means 52 can control a device for driving a brush or the like with the driving device 47 based on the vehicle shape data.

The car wash apparatus 10 configured in this manner has various means (functions), and each means is executed by the control unit 45 . Although each unit has been described as being included in the control unit 45 , it may be provided as a separate member (device) from the control unit 45 .

Next, the operation of the car washing apparatus 10 will be described using the flowchart of FIG. When the user makes a reception on the operation panel 46 [1], the car wash apparatus 10 issues guidance to the user by voice from the notification unit 39 so as to advance the vehicle C to the regular stop position [2]. Furthermore, simultaneously with the voice guidance, the light emitting unit 22 starts emitting light [3], and the top nozzle 28 having the light receiving unit 37 starts moving up and down [4].

The user slowly advances the vehicle C to the normal stop position according to the guidance. At this time, as described above, the light emitting portion 22 projects light onto the boundary lines 23b and 23c of the range 21 of the main body portion 11, and the light receiving portion 37 moves along the boundary lines 23b and 23c as the top nozzle 28 moves up and down. moving up and down along the Therefore, when the light receiving unit 37 cannot detect the light emitted from the light emitting unit 22 while the vehicle C is moving forward, the light emitted from the light emitting unit 22 is blocked because the vehicle C is in a position where the vehicle C cannot be washed. It can be seen that it is not properly approaching toward Therefore, if the light receiving unit 37 does not detect the light emitted from the light emitting unit 22 when the vehicle C enters [5], the user is guided to correct the position of the vehicle by voice from the alarm unit 39 [6].

This guidance allows the user to stop the vehicle on the normal stop position before the cleaning process is started. There is no possibility that the cleaning process will be interrupted due to improper stopping of the vehicle, and the user can feel secure knowing that the vehicle has been parked at the correct position.

The reason why the light receiving part 37 is mounted on the top nozzle 28 and moves up and down on the boundary lines 23b and 23c is that it is possible to detect even if an accessory on the side of the vehicle C, such as a door mirror, partially protrudes outside the washable range. It is for As a result, it is possible to prevent accidents in which accessories such as door mirrors are caught in cleaning bodies such as brushes and are damaged.

Vehicle detection by the light emitting unit 22 and the light receiving unit 37 is performed over time until the vehicle C reaches the normal stop position. The main body 11 is provided with a vehicle stop detection part 41 so that an optical axis is formed on the normal stop position, and it is determined that the vehicle C has reached the normal stop position when the light axis is blocked [7].

After that, the cleaning process by each cleaning equipment is started [8]. For example, when a process (one-way car wash course) is selected in which the main body 11 makes one reciprocation to clean the vehicle, the vehicle detection unit 44 detects the vehicle while moving the main body 11 forward (going travel) as the forward process. Washing water is sprayed on the vehicle C from the top spray 26 and the side spray 27 while detecting C. The vehicle body surface of the vehicle C is brushed and washed using the top brush 24 and the side brush 25 according to the shape of the vehicle C determined by the vehicle detection unit 44 . Next, as a return process, air is blown to the vehicle C using the top nozzle 28 or the like while moving the main body 11 backward (going back) to remove water droplets and dry the vehicle. After that, the car wash apparatus 10 guides the user to leave the car by voice from the notification unit 39, and ends the car wash course.

As described above, in the present embodiment, the light passing/light blocking state between the light emitting portion 22 provided on the ground G and the light receiving portion 37 provided on the top nozzle 28 is known, and the alarm portion 39 emits light according to the state. In this way, it is possible to detect the deviation in the left-right direction of the vehicle traveling toward the normal stop position of the car washing apparatus 10 .

Note that the projection position of the light emitting unit 22 does not necessarily have to be on the boundary line 23 . Even with a configuration in which light is projected outside the range 21 and received by the light receiving portion 37, the vehicle C is outside the washable range due to the blocking of the light transmission, and the vehicle C moves to either the left or right direction of the main body portion 11. It can detect that you are running close to it.

The installation position of the light receiving unit 37 may be appropriately changed according to the light projection position (installation position) of the light emitting unit 22 . For example, if the light-emitting part 22 is installed on the ground G with a width wider than the total width of the nozzle body 71 of the top nozzle 28 , the light-receiving part 37 may be provided on the support 72 .

Further, although the light emitting unit 22 is embedded in the ground G in the present embodiment, the light emitting unit 22 may be housed in a housing or the like standing upright on the ground G. FIG.

Further, since the top nozzle 28 is provided with one light receiving portion 37 on each side in the width direction, the control portion 45 may detect that only the light receiving portion 37 on one side is shielded from light. For example, when only the light-receiving unit 37 on the right side is shielded from light, guidance such as "please move the vehicle to the left side" may be provided.

If only the light receiving portion 37 on one side continues to be shielded, it is assumed that there is an obstacle other than the vehicle C within the travel range of the main body portion 11 . In preparation for such a case, for example, when the light receiving unit 37 on one side is blocked for a certain period of time or more, guidance such as "please call the staff" may be provided.

Further, when the light receiving portion 37 continues to be shielded from light, it is assumed that the size of the vehicle C in the vehicle width direction exceeds the range 21 . For example, when the light receiving unit 37 has been shielded from light for a certain period of time or more, guidance such as "Please confirm whether the size of the vehicle can be washed" may be provided. The car wash staff may be alerted to confirm the size of the vehicle.

After the vehicle C reaches the regular stop position, the cleaning process may not be started immediately, but the top nozzle 28 may be moved up and down from the lower limit to the upper limit to reconfirm the light passing state of the light receiving portion 37 . By performing such control, it is possible to detect whether accessories such as door mirrors protrude out of the washable range even at the position of the vehicle C when the washing operation is started.

(Embodiment 2)
In the above embodiment, the case where the light receiving part 37 is mounted on the top nozzle 28 has been described, but the light receiving part 37 may be any driving part that can be displaced within the opening of the gate-shaped main body 11. can be installed in For example, like the top nozzle 28, it may be mounted on a shaft portion (not shown) of the top brush 24 that moves up and down in the opening of the main body 11, or a side brush that moves forward and backward in the opening from the direction of the leg portions 12a and 12b. 25 (not shown), the side nozzle 38A, or the like. In this embodiment, a case where the light receiving portion 37 is mounted on the side nozzle 38A will be described with reference to the drawings. FIG. 7 is a schematic front view of the car washing apparatus according to this embodiment, and FIG. 8 is a schematic side view of the same car washing apparatus.

The car washing apparatus 10A has a pair of side nozzles 38A (blower nozzles) on each of the legs 12a and 12b of the main body 11 as a washing apparatus. A pair of side nozzles 38A are provided so as to be able to advance and retreat toward the inside of the opening of the main body portion 11 . In the cleaning process, the side nozzle 38A blows air while advancing and retreating along the shape of the vehicle C detected by the vehicle detection unit 44 as the main body 11 moves, and mainly dries the side surface of the vehicle C. can.

An advancing/retreating device for advancing/retreating the side nozzle 38A will be described with reference to FIG. The side nozzle 38A is supported by an air cylinder 53 and moves along a guide frame 54. As shown in FIG. In the standby state, the air cylinder 53 is in a state in which the rod 55 is contracted, and the side nozzles 38A are accommodated in the leg portions 12a and 12b. When air is supplied to the air cylinder 53 in a cleaning process or the like, the side nozzle 38A moves toward the vehicle C with the range of the guide frame 54 as the movement limit. The advance/retreat means of the side nozzle 38A is not limited to the air cylinder, and a motor or the like may be employed.

The side nozzle 38A has a light receiving portion 37A. The light receiving portion 37A has a plurality of light receiving elements 37A-1 to 37A-n provided on the side nozzle 38A so as to extend in the standing direction of the main body portion 11 (the vehicle height direction of the vehicle C). The light receiving elements 37A-1 to 37A-n are provided so as to face the light emitting section 22 so as to receive light projected from the light emitting section 22. FIG. The light receiving portion 37A is displaced outside the washable range 21 of the body portion 11 as the side nozzle 38A advances and retreats. The light-receiving portion 37A can receive light projected from the light-emitting portion 22 when the side nozzle 38A protrudes most toward the vehicle C side.

Next, the operation of the car wash device 10A will be described. When the user accepts the request on the operation panel 46, the car wash apparatus 10A issues a guidance to the user by voice from the notification unit 39 so as to advance the vehicle C to the regular stop position. Furthermore, simultaneously with the voice guidance, the light emitting portion 22 starts to emit light, and the side nozzle 38A having the light receiving portion 37 protrudes from the leg portions 12a and 12b.

The user slowly advances the vehicle C to the normal stop position according to the guidance. As described above, the light emitting portion 22 projects light outside the washable range 21 of the body portion 11, and the light receiving portion 37A is displaced so as to receive the light projected from the light emitting portion 22. FIG. Therefore, when the light receiving portion 37A cannot detect the light emitted from the light emitting portion 22 while the vehicle C is moving forward, the light emitted from the light emitting portion 22 is blocked because the vehicle C is in a position where the vehicle C cannot be washed. It can be seen that it is not properly approaching toward Therefore, when the vehicle C enters and the light receiving section 37A does not detect the light emitted from the light emitting section 22, the user is guided by the voice from the notification section 39 to correct the position of the vehicle.

In this embodiment, the light passing/blocking state between the light emitting unit 22 provided on the ground G and the light receiving unit 37A provided on the side nozzle 38A is known in this way, and the alarm unit 39 issues an alarm according to the state. By doing so, it becomes possible to detect the deviation in the left-right direction of the vehicle traveling toward the normal stop position of the car wash apparatus 10A.

Although the present invention has been specifically described above based on the embodiments, it goes without saying that the present invention is not limited to the above-described embodiments, and can be variously modified without departing from the scope of the invention.

For example, the light receiving part 37 may be provided so as to be displaceable at any position within the washable range of the car washing apparatus 10 . That is, the light receiving section 37 may be mounted on the top nozzle 28 or the like so as to be displaced within the range 21 . With such a configuration, the dimensions of the vehicle C that can be substantially washed by the car washing apparatus 10 are smaller than the maximum allowable vehicle dimensions defined by the structure of the car washing apparatus 10, but the vehicle C is wider than the vehicle width. It is possible to prevent the emergency stop of the car washing apparatus 10 and damage to the equipment during the washing process when the equipment such as a door mirror provided in the direction cannot be detected by the light receiving part 37 due to various factors. can.
