Abstract

PURPOSE:To prevent a car washing machine body from moving and to warn a driver if wheels go past before they come to a stop, by providing warning means which is energized if the time of detection of a wheel by a detecting device is less than a predetermined time. CONSTITUTION:If the time of detection of wheels is less than a predetermined time, a speaker 29 is energized, and issues an announcement 'Wheels exceed a wheel stopping position. Please move this car so that the right wheel comes to a stop before the wheel stopping position'. If the wheel 4 is out of the stopping position, a swing plate 7 is turned to one side thereof about a horizontal center axis 10 by the dead weight of a rear inclined part 13, and accordingly, a cushion 14 abuts against a floor surface 2 so that it is returned into its original posture. Thus, a fulcrum shaft 11 is turned toward the same side so that an actuating element 20 swings downward to depress a detecting arm 19 which turns off a limit switch 17, overcoming an urging force.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car-washing facility for automatically washing a car-washing machine main body when a car to be washed is stopped at a predetermined position.

[0002]

2. Description of the Related Art Conventionally, there is, for example, one shown in FIG. That is, 41 is a car wash main body that can travel back and forth, and at a predetermined position on the front floor surface of the car wash main body 41, a wheel stop portion 44 that specifies a stop position of one front wheel 43 of the vehicle to be cleaned 42 is formed. Has been done. The wheel stop portion 44 is provided with a detection device (not shown) that detects the front wheels 43 in the wheel stop portion 44.

According to this, the vehicle 42 to be cleaned is the main body of the car wash machine.
When the front wheel 43 is stopped in front of 41 and one of the front wheels 43 is stopped in the wheel stop portion 44, the detection device detects the front wheel 43, and the detection determines that the vehicle 42 to be cleaned is stopped at a predetermined position. Then, the car wash machine body 41 automatically advances to carry out a predetermined car wash process.

[0004]

However, in the above-mentioned conventional type, one front wheel 43 of the vehicle to be cleaned 42 passes over the wheel stop portion 44 so that the vehicle 42 to be cleaned comes closer to the car wash machine body 41 than the predetermined position. Even if the vehicle is stopped due to a short period of time, the detection device detects the front wheels 43 for a short time, and therefore the car wash machine body 41 moves forward to perform a predetermined car wash process. However, as described above, since the vehicle to be cleaned 42 comes closer to the car wash machine body 41 than the predetermined position and is stopped, there is a problem that the car wash machine body 41 is not properly cleaned.

Further, there is a problem that the driver does not notice that one of the front wheels 43 has gone too far in the wheel stop portion 44 and stopped as described above. The present invention is to solve the above problems, in the case where the wheels stop too far past the wheel stop,
An object of the present invention is to provide a car wash facility that does not drive the car wash machine body and warns the driver.

[0006]

In order to solve the above-mentioned problems, the car wash equipment according to the present invention has a wheel stop portion for designating a stop position of a wheel of a vehicle to be washed on the running direction side of a car wash machine. A control device for providing a detection device for detecting a wheel in the wheel stop portion, for providing a timer for measuring a wheel detection time, and for causing the car wash machine body to run and start a car wash when the wheel detection time becomes longer than a predetermined time And a warning unit that is activated when the wheel is detected by the detection device and the wheel detection time is a predetermined time or less.

[0007]

According to the above construction, when the wheel of the vehicle to be cleaned has stopped accurately in the wheel stop, the detection device detects the wheel in the wheel stop and the timer measures the wheel detection time. At this time, since the wheel detection time becomes longer than the predetermined time, it is determined that the wheels are correctly stopped in the wheel stop portion, and the car wash machine body travels to start car washing.

Further, when the wheel of the vehicle to be washed passes over the wheel stop portion, the detection device detects the wheel in the wheel stop portion and the timer measures the wheel detection time. However, in the case of overshooting, the wheel detection time becomes less than the predetermined time, so it is determined that the wheels have overrun the wheel stop, and the car washer body does not run and car washing is not started. At this time, since the warning means is activated to issue a warning, the driver in the vehicle to be washed immediately notices that the wheels have gone too far past the wheel stop and immediately moves the vehicle to bring the wheels into the wheel stop. It can be stopped.

At this time, the first timer 26 is activated to measure the elapsed time t1 (step-2). Then, the vehicle to be cleaned 3 is caused to travel along the movement route 24 to the wheel stop portion 5 and it is determined whether or not the limit switch 17 is turned on (step-3). When the limit switch 17 is off, it is determined whether the time t1 is longer than the predetermined time T1 (step-4), and when the time t1 is the predetermined time T1 or less, the process returns to step-2 and the first time continues. The timer 26 is activated to measure the time t1.

Then, in step-4, time t
1 becomes longer than the predetermined time T1, it is determined that the front wheels 4 of the vehicle 3 to be cleaned have not reached the wheel stop 5 as shown by the solid line in FIG. It has not reached the section. Please move the car forward and stop the right front wheel in the wheel stop section "(Step-5). Upon hearing this announcement, the driver immediately notices that the front wheels 4 have not reached the wheel stop 5, and the vehicle 3 to be cleaned is swiftly moved forward to bring the right front wheel 4 into the wheel stop 5. It can be stopped. After that, the first timer 26 is cleared (step-6), and the process returns to step-2.

When the limit switch 17 is turned on in step-3, the second timer 27 is activated to measure the wheel detection time t2 (that is, the time when the limit switch 17 is turned on) (step-7). ).

Then, it is judged whether or not the wheel detection time t2 is less than or equal to the predetermined time T2 (step-8), and if it is less than or equal to the predetermined time T2, as shown by the one-dot chain line (b) in FIG. It is judged that the front wheels 4 have passed the wheel stop 5, and the speaker 29 announces that "the car has gone too far from the wheel stop. Please move the car so that the right front wheel stops inside the wheel stop." It is issued (step-9). Then, the driver immediately notices that the front wheel 4 has passed over the wheel stop portion 5 by listening to this announcement, and promptly moves the vehicle 3 to be washed backward to stop the right front wheel 4 in the wheel stop portion 5. be able to. At this time, the front wheel 4 moves on the rear inclined portion 13 of the swing plate 7 and smoothly fits into the wheel stop portion 5. Then, it is again judged whether the limit switch 17 is turned on (step -10).

When the wheel detection time t2 is longer than the predetermined time T2 in the step-8, it is determined that the front wheels 4 of the vehicle 3 to be cleaned are correctly stopped in the wheel stop portion 5, and it is constant. After a lapse of time, the car wash main body 1 advances to start car washing (steps -11 and 12).

As described above, the vehicle 3 to be cleaned has the wheel stop 5
When the vehicle has not reached the point and when the vehicle has passed the wheel stop 5, the driver can be notified immediately by an announcement, so that the driver notices an error in the stop position and promptly prompts the vehicle 3 to be washed. Can be moved to accurately stop the front wheel 4 in the wheel stop 5.

In the above-mentioned embodiment, the speaker 29 is used as an example of the warning means, but the warning content may be displayed on the electronic bulletin board or the like.
