The wax coating section 5 has a vehicle 7 to be cleaned.
Top brush for wax that applies wax to the upper surface of 14
And a wax rocker brush 15 for applying wax to both side surfaces of the vehicle 7 to be cleaned and the side surfaces of the wheels.

The drying section 6 is provided with a top nozzle 16 for drying the upper surface of the vehicle 7 to be cleaned and side nozzles 17 for drying both side surfaces of the vehicle 7 to be cleaned. The roller conveyors 3a, 3b are a pair of left and right front conveyors 19
a, 19b, intermediate conveyors 20a, 20b, and rear conveyors 21a, 21b. The front conveyors 19a and 19b, the intermediate conveyors 20a and 20b, and the rear conveyors 21a and 21b each have a driving electric motor (not shown), and are independently driven by a pair of left and right. . The front conveyors 19a and 19b are installed in front of the car wash main body 2, the intermediate conveyors 20a and 20b are installed from the front of the car wash main body 2 to the back of the cleaning part 4, and the rear conveyors 21a and 21b are wax application parts. Car wash machine body 2 from 5
It is installed behind.

As shown in FIG. 1, the rear conveyor 21
A pair of left and right safety fences 24a and 24b are provided at the unloading portions of a and 21b. One safety fence 24a is installed outside one rear conveyor 21a, and the other safety fence 24b is installed outside the other rear conveyor 21b. These safety fences 24a, 24b are respectively formed by a pair of front and rear vertical rods 26, 27 standing on the floor 1 and a horizontal rod 28 continuous between the upper ends of these vertical rods 26, 27. ing. Of these, the front vertical rod portion 26 is provided adjacent to the rear surface of the car wash machine body 2,
The rear vertical rod portion 27 is provided at the end of the rear conveyors 21a and 21b.

A photoelectric switch 29 (an example of a detection device) for detecting the vehicle to be cleaned 7 located at the carry-out portion is attached to the upper portion of the rear vertical rod portion 27 of both safety fences 24a and 24b. That is, the projector 30 is attached to the rear vertical rod 27 on one side, and the light receiver 31 is attached to the rear vertical rod 27 on the other side. This allows the light emitted from the projector 30
An optical axis 32 is formed from the light projector 30 toward the light receiver 31.

The front conveyors 19a and 19b, the intermediate conveyors 20a and 20b, and the rear conveyors 21a and 21b are control devices.
Drive-controlled by 34. When the photoelectric switch 29 detects the vehicle 7 to be cleaned for longer than a predetermined time, the control device 34 controls the front conveyors 19a and 19b and the intermediate conveyor.
It has a function of emergency stop of 20a, 20b and rear conveyors 21a, 21b.

The predetermined time means that the vehicle to be cleaned 7 has the optical axis 32.
The time required to pass by (that is, the vehicle to be washed 7
Is obtained by dividing the total length of the above by the conveying speed of the rear conveyors 21a and 21b), and some margin time (for example, several seconds) is added. The car wash main body 2 is provided with a timer (not shown) for measuring the predetermined time. Further, as shown in FIG. 4, a sonic sensor 35 for detecting the height and the total length of the vehicle 7 to be cleaned is provided on the front surface of the car wash machine body 2.

The operation of the above structure will be described below.
As shown by the solid line in FIG. 4, the vehicle to be cleaned 7 is a front conveyor.
Get on the starting points of 19a and 19b and stop. Then, the front conveyors 19a and 19b, the intermediate conveyors 20a and 20b, and the rear conveyors 21a and 21b are driven, and as shown in FIG.
The vehicle 7 to be cleaned is conveyed from the front conveyors 19a, 19b to the rear conveyors 21a, 21b via the intermediate conveyors 20a, 20b. During this time, the vehicle 7 to be cleaned is cleaned by the brushes 11, 12, 13 while being conveyed inside the car wash machine body 2 after the full length is detected by the sonic sensor 35, and the brushes 14, 15 are cleaned.
The wax is applied by the above and dried by the top nozzle 16 and the side nozzles 17. Then, the vehicle 7 to be cleaned is carried out to the floor 1 from the carry-out part (that is, the end part) of the rear conveyors 21a and 21b.

At this time, as shown in FIG. 3, the vehicle 7 to be washed out is detected by the photoelectric switch 29 because it blocks the optical axis 32, but it is detected between the light projector 30 and the light receiver 31 within a predetermined time. Pass through. As a result, the light from the projector 30 is transferred to the receiver 31.
Then, the optical axis 32 is re-formed and the photoelectric switch 29 becomes non-detected.

In the unlikely event that the vehicle 7 to be cleaned has the rear conveyor 21a,
If the vehicle to be washed 7 is stuck due to a trouble such as derailment at the carry-out section of 21b, the stuck vehicle 7 to be cleaned is blocked by the optical axis 32 and detected by the photoelectric switch 29. At this time, since the vehicle 7 to be cleaned remains stuck even after a predetermined time has passed,
The photoelectric switch 29 will detect the vehicle 7 to be cleaned longer than the predetermined time. As a result, the controller 34 causes the rear conveyors 21a and 21b, the intermediate conveyors 20a and 20b, and the front conveyors 19a and 19b to stop in an emergency. Therefore, the vehicle 36 to be cleaned next conveyed is prevented from colliding with the vehicle 7 to be cleaned previously conveyed and stuck.

Further, since the safety fences 24a and 24b are provided at the carry-out portions of the rear conveyors 21a and 21b, it is possible to prevent a person from unnecessarily invading the carry-out portions, and the safety is improved. Furthermore, since the photoelectric switches 29 are provided on the safety fences 24a and 24b, the columns for mounting the photoelectric switches, etc. are separately provided on the floor 1.
There is no need to install it in. Therefore, it is possible to reduce the problem that the operator inadvertently damages the photoelectric switch 29 and to simplify the design.

In the above embodiment, the roller conveyors 3a and 3b are provided as an example of the conveying device, but they may be belt conveyors or chain conveyors. Further, the roller conveyors 3a, 3b are divided into three parts, namely the front part conveyors 19a, 19b, the intermediate part conveyors 20a, 20b and the rear part conveyors 21a, 21b, but this may be a single structure rather than a divided structure. .

In the above embodiment, the photoelectric switch 29 is used as an example of the detecting device, but an ultrasonic detector may be used instead. In addition, in order to notify the worker when the photoelectric switch 29 detects the vehicle 7 to be cleaned for longer than the predetermined time,
The indicator light may be turned on or the buzzer may sound.

[0023]

As described above, according to the present invention, if the vehicle to be cleaned gets stuck due to a trouble in the carry-out section of the transporting device, the detecting device makes the stuck vehicle to be cleaned longer than a predetermined time. For detection, the controller stops the carrier. This prevents the next vehicle to be washed from colliding with the stuck vehicle to be washed.

Further, since the carrying-out section of the carrying device is provided with the safety fence, it is possible to prevent a person from unnecessarily entering the carrying-out section, and the safety is improved. Further, since the above-mentioned detection device is provided on the safety fence, it is not necessary to separately install a column or the like for mounting the detection device, and a thimble design can be achieved.
