Abstract

PURPOSE:To prevent door mirrors from damages due to side brushes in a car washing machine by spacing the side brushs sideways of a vehicle from the portions of the side mirrors. CONSTITUTION:When side brushes 7 come to positions 7A, a top brush 6 is located in a position 6A and abuts against the front window of a vehicle to pivot along the forward direction 8 to the rear side so that a magnet 20 is opposed to a contact element 21 and the detecting signal is sent to the input of an electronic circuit. After a predetermined first set time T1, i.e. when the side brushes 7 come to positions 7B, the side brushes 7 move outward sideways and part from the sides of a vehicle V. Next, when second set time T2 elapses after the beginning of outward sidewise shift of the side brush 7, the side brushes 7 begin to approach the vehicle V so that door mirrors can be prevented from damages due to the side brushes.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a washing method using a car wash machine, and particularly to a gate-shaped frame that can straddle a vehicle to be washed and run along the longitudinal direction of the vehicle. It is equipped with a movable top brush and a pair of side brushes that are placed behind the top brush in the traveling direction and can move laterally in a direction perpendicular to the traveling direction of the portal frame. This invention relates to a washing method using a car wash machine in which a frame moves back and forth.

Conventionally, when such a car wash machine washes a vehicle equipped with a door mirror, the door mirror may be damaged by the side brush because the door mirror protrudes to the side of the vehicle.

SUMMARY OF THE INVENTION An object of the present invention is to provide a washing method using a car wash machine that prevents the side brush from being damaged by the side brush by moving the side brush away from the side of the vehicle at the side mirror.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. First, in FIG. The wheels 3 are placed on a rail 4 extending along the longitudinal direction of the vehicle, and one of the wheels 3 is

The portal frame 2 is provided with a rotating brush device B, a drying device, and other processing devices (not shown), and the operation of the traveling drive device M, the rotating brush device B, the drying device, and other processing devices is as follows. Control panel 5 installed on gate-shaped frame 2
controlled by internal electronic circuitry (not shown).

Referring also to FIG. 2, the rotating brush device B includes a top brush 6 and a forward direction (
1) and a pair of side brushes 7 disposed on the rear side of the top brush 6.

The top brush 6 is swingably supported via a swing arm 10 on a horizontal shaft 9 that is rotatably supported on the portal frame 2 . A prime mover 11 is provided on the upper part of the swinging arm 10 , and the top brush 6 is rotationally driven from the prime mover 11 via a transmission mechanism within the swinging arm 10 . Further, a sprocket 12 is fixed to the horizontal shaft 9, and a drive shaft 13 is rotatably supported on the portal frame 2 on the side of the horizontal shaft 9. 14 is fixed. An endless chain 15 is suspended from both sub-blocks 12 and 14. The drive shaft 13 includes a piston rod 1 of an air cylinder 17 whose lower end is supported by the portal frame 2.
B is concatenated. However, by driving the air cylinder 1T to extend, the top brush 6 can be held in the upper storage position as shown by the two-dot chain line. Furthermore, when the air cylinder 17 is inactivated, the top nozzle 6 can freely swing about the horizontal axis 9 between its vertical position and the storage position, and the top brush 6 can be moved freely during the cleaning process. contacts the top surface of the vehicle and swings according to the shape of the top surface of the vehicle.

An arm 19 is fixed in the middle of the horizontal shaft 9, and the arm 19 projects toward the traveling direction 8 when the top brush 6 is in a position hanging from the horizontal shaft 9. Magnet 20 is fixed. On the other hand, a contact element 21 that switches when facing the magnet 20 is fixedly disposed on the gate-shaped frame 2. When it is angularly displaced by a certain amount toward the rear, it is placed at a position facing the magnet 20.

The magnet 20 and the contact element 21 are used to detect the front window of the vehicle, and a detection signal from the front window is input to an electronic circuit in the control panel 5.

The rotating shafts 22 of the pair of side brushes 70 are held in a holding cylinder 23 extending vertically, and the holding cylinder 23 is connected to the moving frame 2.
Fixed to 4. The moving frame 24 is slidably engaged with a guide rail 25 that extends horizontally on the gate-shaped frame 2, and is laterally driven by a driving means (not shown). Also, the guide rail 250
Both ends are rotatably supported on the portal frame 2 via a support shaft 26, so that the guide rail 25 and the moving frame 2
4, the holding cylinder 23, the rotating shaft 22 and the side brush 7,
The gate-shaped frame 20 can swing along the running direction using the support shaft 26 as a fulcrum. Further, a prime mover 27 is supported on the movable frame 24, and a sprocket 28 fixed to the output shaft of the prime mover 27 and a sprocket 29 fixed to the end of the rotating shaft 22 have an endless chain 30 is suspended, and the side brush 7 is driven by the prime mover 27.
is driven to rotate.

The drying device consists of a pair of side air blowing nozzles 31 that open inward on both sides of the portal frame 20, and a top air blowing nozzle 32 that opens downward at the top, which are connected to a blower 33. The nozzle 32 is raised and lowered by a lifting means (not shown) in accordance with the height of the vehicle to be dried.

Next, the operation of the rotary brush device B during the cleaning process will be explained with reference to FIGS. 3 and 4. During the cleaning process, the portal frame 2 travels in the forward direction 8, Thus, the cleaning process of the vehicle V is completed.

When the gate-shaped frame 2 starts moving forward, both side brushes 7 are located at the innermost position, and when the gate-shaped frame 2 comes to the position where it comes into sliding contact with the front surface of the vehicle r, they are temporarily moved to the outside while cleaning the front surface. The vehicle V is then moved inward and further inward to wash the side surface of the vehicle V. When this side brush 7 comes to the position shown by 7A, the top brush 6 moves to 6 in FIG.
At the position indicated by A, the contact element 21 is in contact with the front windshield of the vehicle and rotated 1- rearward along the forward direction 8, and the magnet 20 faces the contact element 21, and a detection signal is input to the electronic circuit. When a predetermined first set time T has elapsed since this detection signal was input, the vehicle moves away from the side of the vehicle V. Next, when the second set time T2 has elapsed from the start of the outward movement of the side brushes 7, the side brushes 7 start approaching the vehicle V.

The first set time T1 is for the top brush 6 and the side brush 7.
The time from when the top brush 6 reaches the installation position of the door mirror DM, that is, near the front window part, to when the side brush 7 comes to a position close to the door mirror DM, is calculated according to the distance between the gate frame 20 and the door mirror DM. It is set based on speed. Further, the second set time T2 is preset as a sufficient time for the side brush 7 to separate from and pass the door mirror DM.

After the second set time T.2 has elapsed, the side brush 7
When the gate-shaped frame 2 passes the vehicle V, it reaches the closed position indicated by IC, and the cleaning process is completed.

In this way, the side brush 7 is operated to separate from the vehicle V when it comes to the position corresponding to the door mirror DM,
Therefore, the side brush 7 is prevented from coming into contact with the door mirror DM, and as a result, damage to the door mirror DM is prevented.

9- As described above, according to the present invention, the side brush of the gate-shaped frame is moved away from the side of the vehicle for a second set time, and after the second set time has elapsed, the side brush is moved closer to the side of the vehicle. Therefore, by using the upward rotation of the top brush in the front window of the vehicle, the system detects the door mirror that is located almost in line with the front window.
The side brush can be moved away from the side of the vehicle so as not to come into contact with the door mirror, and the side brush can be prevented from coming into contact with the door mirror, thereby preventing damage to the door mirror.
