Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method of washing a vehicle using a car wash machine.

Conventional technology In the conventional method of washing a wagon using a car wash, when a sonic sensor detects that the vehicle is a wagon, the side brush always removes the wide mirrors that protrude in front of the wagon and are attached to both sides. A wide mirror escape process was included in the car wash process.

Hereinafter, the method for cleaning the wide mirror escape process for a wagon will be explained based on the drawings.

FIG. 6 is a schematic diagram of a conventional car wash machine. In FIG. 6, reference numeral 1 denotes a gate-shaped car washing machine main body that can run freely in the front and back direction of the vehicle 2, straddling the vehicle 2 to be washed.
A sonic sensor 3 is provided to detect the vehicle height and identify the model of the vehicle 2, and an upper brush 4 for washing the upper part of the vehicle 2 is provided at the rear of the car wash main body 1.
A pair of side brushes 5 are provided which are movable in a direction perpendicular to the running direction of the car wash main body 1 and wash the front, rear, and both sides of the vehicle 2. The sonic sensor 3 detects the vehicle height when the vehicle 2 is placed in a predetermined position, and detects the height of the wagon 6 because the vehicle height is high.
When it is detected that the main body 1 of the car wash machine is
moves forward (to the left in the figure) and when the side brush 5 comes into contact with the wagon 6, the car washer body 1 stops moving forward, moves the side brush 5 in a direction perpendicular to the running direction of the car washer body 1, and then moves the side brush 5 toward the wagon 6. A part of the front of the car 6 is washed. And wide mirror 7 of wagon car 6
To escape, the car wash main body 1 is moved backwards (step back), the side brushes 5 are further moved to a position where they do not touch the wide mirror 7, and in the open state, the car wash main body 1 is moved forward again, and the side brushes 5 are After passing by the wide mirror 7 and reaching a position where it does not come in contact with it, the side brush 5 is moved to a position where it contacts the wagon 6, and the side brush 5 cleans both sides of the wagon 6.

Problems to be Solved by the Invention However, some wagon cars 6 are equipped with a wide mirror 8 of a door mirror type that does not protrude from the front of the car body, as shown by the broken line in FIG. Stepbacks are no longer necessary. Furthermore, when the car was washed with the wide mirror relief process included, a spot 9 was left unwashed at the front of the wagon 6, as shown in FIG.

The present invention solves the above-mentioned problems, and aims to provide a washing method using a car wash machine that eliminates the step-back of the car wash machine body depending on the type of wide mirror.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a gate-shaped car wash machine body that can run freely in the front and rear directions of the vehicle across the vehicle to be washed, and a front upper part of the car wash machine body. a pair of side brushes provided on the car wash machine body and movable laterally in a direction perpendicular to the running direction of the car wash machine body; a control unit incorporating a cleaning process having a step-back function for causing the car wash machine main body to move backward once the front part of the vehicle is being cleaned by the side brush when the vehicle is determined to be a wagon based on the detection signal of the detection means; and a switch connected to the control section to inhibit the step-back function, and when the switch is operated based on confirmation of the wide mirror type of the vehicle, the vehicle is moved to a wagon position based on a detection signal from the vehicle height detection means. If it is determined that the vehicle is a car, the main body of the car washer is advanced until the side brushes contact the front of the vehicle, the entire front of the vehicle is washed while opening the side brushes, and then the main body of the car wash is moved to a position where it does not come into contact with the wide mirror. The side brushes are further opened to move the car wash machine forward and avoid the wide mirror.

Operation With the above configuration and method, by confirming the type of wide mirror of the vehicle to be cleaned and operating the switch that prohibits step-back,
The step of the car wash machine main body stepping back is omitted, and when the front part of the wagon car is washed with the side brush, the entire front part of the wagon car is washed with the side brush without the car wash main body stepping back.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings.

FIG. 1 is a schematic diagram of a car wash machine showing an embodiment of the present invention. Components that are the same as those in the conventional example are given the same reference numerals and descriptions thereof will be omitted. In Figure 1, 1
Reference numeral 1 denotes a gate-shaped car washing machine that can straddle the vehicle to be washed (in this embodiment, a wagon 13 having a door mirror type wide mirror 12) and can freely run in the front and rear directions of the vehicle (in this embodiment, a wagon 13). The main body 11 of the car wash machine has a sonic sensor 3, an upper brush 4, a side brush 5, etc. built in, and an operation surface 1 on the front of the car wash main body 11.
A control device 15 with 4 is provided. In addition to the control switches 16, the operation surface 14 is provided with a "stepback off" switch 17 for inhibiting the stepback of the car wash main body 11, as shown in FIG. Further, the control device 15
As shown in FIG. 3, the outputs of the sonic sensor 3 and the "stepback off" switch 17 are inputted via input sections 18 and 19 to a control section 20 incorporating a cleaning process with a stepback function. Judgments and calculations are made based on the output of the sensor 3 and the state of the "step back off" switch 17, and the main body 11 of the car wash machine, which can freely travel in the front and back direction, the side brush 5, etc. are controlled via the output parts 21 and 22.

Hereinafter, a method of washing a vehicle using the car wash main body 11 and the side brush 5 controlled by the control device 15 will be explained with reference to the control flowchart shown in FIG. When a car wash starts, the height of the vehicle is determined based on the output of the sonic sensor 3 (step 1).
31) If the vehicle height is low, a cleaning process for a regular type vehicle is carried out (step 32), and if the vehicle height is high like wagon 13, then it is confirmed that the type of wide mirror 12 is a door mirror type. Then, it is determined whether the "step back off" switch 17 has been operated (step 33). If the "step back off" switch 17 is not operated, a wide mirror relief step is added to the washing process for the wagon, and the washing is carried out in the same manner as in the conventional case (FIG. 7) (step 34). If the "step back off" switch 17 is operated, the wagon 1 having a door mirror type wide mirror 12
5 and performs cleaning without the wide mirror relief process (step 35). That is, as shown in FIG. 5 as a locus of the side brush 5, the side brush 5 first moves the car wash machine main body 11 to the wagon 13.
The side brush 5 is moved forward until it comes into contact with the front part of the wagon car 15 and then stopped, and the side brush 5 is moved in a direction perpendicular to the running direction of the car washing machine main body 11 and is opened left and right to completely wash the entire front part of the wagon car 15. Following washing of the front part of the wagon 15 by the side brush 5, the side brush 15 is further opened and retracted to a position where it does not come into contact with a wide mirror 12 of a door mirror type, and the car washing machine main body 11 is moved forward again. Next, as the car wash main body 11 moves forward, the side brush 5 passes by the wide mirror 12 of the door mirror type and comes to a position where it does not come into contact with the wide mirror 12, and then closes the side brush 5 to a position where it contacts the wagon 13. Then, the side brush 5 is used to clean both sides of the wagon 13.

In this way, in the case of a wagon 13 having a door mirror type wide mirror 12, by confirming that the wide mirror 12 is a door mirror type and operating the "step back off" switch 17, the car wash main body 11 can be turned off. The entire front part of the wagon 15 can be washed with the side brush 5 without wasting any waste and without stepping back.

Effects of the Invention According to the present invention, the car wash machine main body is provided with a switch that is operated when the step-back is not performed, and by operating the switch after confirming the type of wide mirror of the vehicle to be washed, the car wash machine The main body can be cleaned without unnecessary step-backs, and with the side brush, the entire front part of the wagon can be cleaned without leaving anything unwashed. Therefore, it is possible to save the labor of hand washing by the worker, thereby reducing the labor of the worker and improving the work efficiency.
