Abstract

PURPOSE:To achieve two brushings during a reciprocation of washing and to complete washing of a very dirty car in a short time by controlling air cylinders so as to carry out brushing in the advancing and returning travels with a brush swinging up in the same direction. CONSTITUTION:A top brush 3 is supported by swing arms 5, 5' through shafts 4, 4' on both sides of a body 1. It is rotated by a motor 6 fixed to one swing arm 5. The top brush 3 is vertically moved by an air cylinder 8 through a transmission arm 9 so as to clear obstacles to washing, and a top nozzle 11 is driven for vertical movement by an air cylinder 15 of a link arm 14 so as to keep a required space with respect to the body. During washing, the air cylinder 8 is kept open to the atmosphere to lower the top brush 3. When washing, the air cylinder 8 is kept open to the atmosphere in the advancing travel and air pressure is applied thereto in the returning travel, so that the top brush 8 swings in the same direction in both travels and brushing and drying are carried out in the returning travel.

Description

[Detailed description of the invention]

The present invention relates to a car wash machine equipped with a circular 7-striped inner slit cleaning brush that travels back and forth across a vehicle. In general, this divine car wash machine has a car wash machine body 1 that runs on rails 2 and 2', as shown in fjSI diagrams (a) and (b).
A piece of swinging arm 6,6't is supported at both ends, and is equipped with a top brush 3 that swings when it comes into contact with the vehicle V. Brushing is performed while tracing the vehicle body, and the top brush 3 is 7'L when going out and going back.
Each swings in opposite directions. Also, normally in this type of car wash machine, the front edge of the circular frame 1 is not good! It is customary to use a blower 7 and nozzle 11 to blow air onto the car body to dry the car body at the end of washing. Figure 1(a)
As shown in the figure, the vehicle is brushed and cleaned, and during the return trip, the blower nozzles 11 and 12 are used to dry the vehicle. However, as mentioned above, when washing a car in one round trip, only one person can brush the car on the way out, and in the case of a heavily dirty car, it is often impossible to completely remove the dirt. Even if I try, it doesn't work as shown in Figure 1 (
As shown in b), the top brush 3 is swung in the opposite direction from when it is moving, which impedes drying by the blower nozzle 11. Therefore, in the past, the main body 1 moved back and forth twice to brush a heavily soiled car more than once, but it took a long time to wash the car, and it was not convenient for customers in a hurry. It was something. This invention has been made in response to the above-mentioned problems, and includes:
To provide a device which enables brushing to be performed twice in a reciprocating car wash and can complete cleaning even a heavily soiled car in a short time. Hereinafter, a specific example thereof will be explained based on the illustrated embodiment.

It is formed so that it can swing along the shape of the vehicle body, and is normally held in the standby position as shown in the figure. Reference numeral 6 denotes a motor fixed to one swing arm 5, which rotates and moves the brush 3. 7 and 7' are weights fixed to the ends of the swinging arms 5 and 5' opposite to the brush support side, which reduce the swinging moment of the brush 3 and allow the brush 3 to swing smoothly through contact with the intermediate rest. It is equipped to move as much as possible. 8 is an air cylinder that moves the top brush 3 up and down via a transmission arm 9, and provides operations such as avoiding obstacles in car washing. In addition, the transmission arm 9 is the swing arm 5, 5'
It is fixed to the shaft 4 at a certain angle to the rear side, and is configured so that even if the air cylinder 8 is driven while the top brush 3 is heavily lowered, it will always be swung up to the rear. 10 is a tilt sensor that provides rotation data of the shaft 4. It has a rotating body that follows the rotation of the shaft 4, and is composed of a so-called encoder that emits a pulse every time this rotating body rotates by a certain angle. Arm 5
・The tilt position of 5' is detected. Reference numeral 11 indicates a top nozzle provided in the main body 1, which is connected to blowers 12 and 12'' through flexible ducts 13 and 13', and is movable up and down by a link arm 14. Reference numeral 15 is a top nozzle. Air cylinder that drives the nozzle 11 up and down. 16
is an idle ring attached to the tip of the top nozzle 11, which rotates in contact with the vehicle body when the top nozzle 11 operates, maintains the necessary distance from the vehicle body, and adjusts the contact pressure with the single body by %[t]. The air valve 17 is operated to raise and lower the air cylinder 15. Reference numeral 18 denotes a motor that rotationally drives the wheels 19 of the main body 1. Reference numeral 20 denotes a reset position sensor that is provided on the 1F section of the main body and switches by sensing a curved piece 21 provided at the rear end of the rail 2.

FIG. 4 is an explanatory diagram mainly showing the pneumatic pipe line in the air cylinder 8 and its control circuit in the embodiment. Pneumatic pressure is appropriately introduced into the boat of F-SIRING-8 from an air pressure source 30 by boiling the switching valves 31 and 32 and the pressure regulating units t) 3'J and 34. Switch fF31 is on the right side of fire release bow) 35, and when using knob brush 3

[Here, open the air cylinder 8 to the flame and lower the top brush 3. The switching valve 32 is used to appropriately switch the air pressure introduced into the FSI ring 8, and the air pressure P+ (in this example, 6 to 7 kg/cm2) introduced via the pressure regulating unit 33 forces the top brush 3 into its state. The air pressure 1"2 (in this example, about 2 kg1cII+) introduced through the pressure regulating unit 34 is used to raise the top blank to the upper waiting position, and the top It is used to reduce the load when the brush 3 rises due to contact with the upper body.Therefore, in the air cylinder-8, air pressure P is normally introduced through the pressure regulating unit 33, 3 is held in the t!I position, and when washing the car, the switching valve 31 is switched, the air cylinder 8 is opened to the air, the top cylinder 3 is raised F, and the main body is moved back and forth during the car wash. Brushing at the time is done with this scale 1 (in the open state, and when going back, switch the switching valves 31 and 32, and use the air cylinder -8, \
Pneumatic pressure P2 is introduced. 35, 36, 37, 38, and 39 are drive circuits for the switching valves 31, 32, motor 6, blower 12, 12', and the switching valve (not shown) of the top nozzle air cylinder 15, and 40 is the drive circuit 35, 36.・37

The program operates with reference to the equal detection signals. Fig. 5 is a 70-chart showing a partial summary of the program registered in the ROM of the control device 38, and Fig. f5G shows the car washing operation of the embodiment. This is an explanatory diagram, and the operation of the embodiment will be explained below based on these two diagrams. When the car wash is started in response to an operation input on the operation panel 22 and the forwarding process begins (1), the switching valve 31 is switched to air cylinder. -8 is opened to the atmosphere and the top bracket is lowered, at the same time the motor 6 is driven and the top surface is brushed (2).
When the tilt sensor 10 confirms that the top brush has drooped (3), reduce the drive of the motor 6 by one step (4)
. Then, when entering the go-around process (5), the switching valves 31 and 32
When the air pressure P2 is introduced into the air cylinder 8 and the motor 6 is driven to start brushing, the blower 12. Drying is started by lowering the top nozzle 11 (7). During the go-around, if the top brush 3 were to swing in the opposite direction to the direction of the go-around due to being pushed by the surface of the vehicle, this would be detected based on the signal from the tilt sensor 10 (8), and the motor 18 would be immediately activated. Stop the main body 1
