Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a vehicle top surface cleaning device that is moved vertically to clean the top surface of a vehicle body.

Conventionally, as a top surface cleaning device for a vehicle, a top brush is pivotally supported vertically via a pair of swinging arms on a gate-shaped frame formed so that the vehicle can pass through. It is known that the top brush is moved up and down along the top surface of the vehicle body to clean that surface by swinging the top brush up and down around a shaft fulcrum. In order to clean the vehicle even when the vehicle is being washed, the swing arm must be made relatively long, which requires a relatively large installation space. For example, when a vehicle enters a portal frame from the front, the top brush moves from the hood surface of the vehicle to the front window surface. When moving from the roof surface to the rear window surface, the swinging arm is placed at an angle close to perpendicular to the front window surface, increasing the blood pressure of the brush and enabling efficient cleaning.On the other hand, when moving from the roof surface to the rear window surface, the swinging arm The brushes become parallel to the rear window surface, reducing the surface pressure of the brushes, which not only reduces cleaning efficiency but also tends to leave unwashed residue.

Therefore, the present invention is designed to greatly reduce the space required for the top brush by arranging it so that it can move up and down vertically along the top surface of the vehicle body without using a swinging arm. It is an object of the present invention to provide an apparatus for washing the upper surface of a vehicle, which can wash the upper surface of the vehicle body uniformly and evenly with a substantially constant blood pressure at all times by controlling the top brush to move up and down accordingly.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a frame formed in a gate shape so that a vehicle can pass through the frame, and the frame 1 includes rails 2 laid on the ground,
2 via guide wheels 3, 3, and is configured to travel back and forth on the rails 2, 2 by the drive of a prime mover (not shown).

On both sides of the frame 10, a pair of guide rails 4.4 that face each other and extend vertically are supported so as to be swingable in the front and rear direction. Each guide rail 4 is fixed to a support member 6 that is rotatably supported in the vertical direction at the upper part of both sides.
The lower ends of the coil springs 7a, 7b are elastically supported by a pair of coil springs 7a, 7b to allow the reframe 10 to swing in the front-rear direction.
The guide rails 4, 4 are held in place by the coil spring 7 until a rotational force exceeding the set load of
It is held in a vertical neutral position by a and 7b.

A pair of limit switches 8a and 8b are provided at the lower part of one side of the frame 1, sandwiching one of the guide rails 4 at equal intervals in the front and back direction, and at the lower end of the guide rail 4, limit switches 8a and 8b are provided. Actuator 9
is formed, and the guide rail 4 swings from a vertical neutral position through a certain angle in the front and back direction with respect to the frame 1 using the fixed pin 5 as a pivot point against the set loads of the coil springs 7a and 7b. At this time, the limit switch 8a or 8b is actuated by the actuator 9 at the tip of the guide rail 4, and the brush moving motor 23, which will be described later, is actuated.

A movable carriage 13.13 supporting the brush support shaft 12 is provided on the guide rail 4.4 so as to be movable up and down via guide rollers 14, 14 provided with a flange. 13.13 is moved up and down along the guide 1/-role 4.degree. 4 by a lifting device 15, which will be described below.

Next, the elevating device 15 will be explained. Elevating and lowering chinos 16 are provided on the upper and lower edges of each mobile cart, and the supporting members 6,
A chain wheel 19 fixed to a rotary shaft 18 rotatably supported on the frame 1 through a bracket 17.17 and a chain wheel 20 pivotally supported on the frame 1 are suspended and connected to one end of the rotary shaft 18. As shown in FIG. 2, the driven sprocket 21 is fixedly connected to the driving sprocket 24 which is connected to the output shaft of the brush moving motor 23 via a transmission chain 722. The rotating shaft 18 is rotated in one direction by the normal rotation drive of
3 is lowered, and when the motor 23 is driven in reverse, the movable trolley 13.13 is raised.

Brush support shaft 1 fixedly supported between movable carts 13 and 13
2, a hollow cylindrical transmission shaft 26 is rotatably fitted into the transmission shaft 26, and a top brush 28 for cleaning the upper surface of the vehicle body is rotatably attached to the transmission shaft 26. A driven sprocket 27 is fixed to one end of the transmission shaft 26, and this driven sprocket 2
7, the drive sprocket 31 fixed to the output shaft 30 of the brush drive motor 29 fixedly supported by the support shaft 12 is linked via the bracket 25 to the drive sprocket 31 fixedly attached to the output shaft 30 of the brush drive motor 29 via the transmission chain 732. Output shaft 3
0, the top brush 28 can be rotated by rotating the transmission shaft 26 through the drive sprocket 31, the transmission chain 732, and the driven sprocket 28.

The drive sprocket 27, 31 and the transmission chain 732 are built into the bracket 25.

Next, the operation of the apparatus of the present invention will be explained with reference to FIG.

Now, when you press the start button (not shown) on the car wash device,
The brush drive motor 29 starts and the top brush 28 is driven to rotate, but at this time the top brush 28 is held at the upper limit position (FIG. 3(a)) and idles, and the brush moving motor 23 is driven to rotate in the forward direction. The movable carriages 13, 13 are then lowered along the guide rails 4, 4, and the top brush 28 supported by the movable carriages 4, 4 is thereby also moved downward.

When the top brush 28 has descended to the lower limit position (FIG. 3(b)), the operation of the brush moving motor 23 is stopped, and the frame 1 of the car wash machine is moved forward with respect to the vehicle V by the drive of a driving motor (not shown). In other words, it starts going back and forth. When the frame 1 moves forward and reaches the front end of the vehicle, the 1-tub brush 28 comes into contact with the front end of the vehicle body, increasing its surface pressure, and in order to prevent this pressure from exceeding a set value, the guide rails 4, 4 are activated by the coil springs 7a. The limit switch 8a is swung backward around the fixing pins 5, 5 against the elastic force of the guide rail 4 (FIG. 3(C)), and the limit switch 8a is actuated by the actuator 9 at the tip of one of the guide rails 4.
The brush moving motor 23 is driven in reverse to move the top brush 2
8 is the rising figure 3 (d). The operation of the top brush motor 23 is stopped for a certain period of time, and the top brush 28 is held at a certain height, and as the frame 1 moves forward, the bonnet surface at the front of the vehicle body is cleaned (FIG. 3(e)). After a certain period of time,
When the timer is deactivated, the brush moving motor 23 is driven in normal rotation, and the top brush 28 begins to descend again.As a result, the surface pressure increases and exceeds the set value, and as described above, the guide rail 4. 4 is swung forward, the limit switch 8a is actuated by the actuator 9 at its tip, and the brush moving motor 23 is driven in reverse to raise the top brush 28. From then on, the top brush 28 repeats the raising and lowering operation and moves to the front window. surface, roof surface, rear window surface, trunk lid surface, etc., are cleaned evenly with a substantially constant surface pressure along their uneven shapes.

When the top brush 28 finishes cleaning the trunk lid surface at the rear of the vehicle body and moves away from the rear end, the blood pressure of the top brush 28 becomes less than the set value, the brush moving motor 23 is rotated forward, and the top brush 28 is moved to the lower limit position. The lower limit switch (not shown) is lowered to activate the lower limit switch (not shown), thereby stopping all operations of the brush drive motor 29, the brush moving motor 23, the motor for driving the car wash machine (not shown), etc.

After a few seconds, the brush moving motor 23 is driven in reverse again to raise the top brush 28. When the top brush 28 reaches the upper limit position, an upper limit switch (not shown) is activated to stop the brush moving motor 23 from operating. At the same time as the stop, the traveling prime mover is activated, and as a result, the frame 1 begins a go-around and returns to the starting position, and at the same time, the traveling prime mover is deactivated by the activation of a start position detection limit switch (not shown). The car wash machine enters the period state.

In the above description, the limit switches 8a+8b constitute the swing amount detection element of the present invention.

In the above embodiment, a case has been described in which the car wash machine is moved relative to the vehicle, but it goes without saying that the vehicle may be moved relative to the car wash machine.

As described above, according to the present invention, a pair of guide rails are suspended from both sides of a frame formed in a gate shape so that vehicles can pass therethrough, so as to be swingable in the direction of relative movement between the frame and the vehicle body. Each of the guide rails is provided with a movable carriage that can be moved up and down along the guide rail, and a top brush for cleaning the upper surface of the car body is connected between the movable carriages so as to be able to rotate around a substantially horizontal axis. is equipped with a brush moving motor capable of raising and lowering the movable trolley, and further provided with a pair of swing amount detection elements on the frame, sandwiching the one guide rail in the swing direction thereof, and with a brush moving motor on the guide rail. , an actuator is provided for activating the swing amount detection element when it is swung by a predetermined angle or more in the longitudinal direction from a vertical neutral position, and the plan movement motor is driven by the operation of the swing amount detection element to Since the top brush is controlled to rise and fall, the top brush can be moved up and down vertically along the top of the car body, and unlike conventional models, the top brush is pivoted so that it can swing vertically using a swinging arm. Compared to the above, there is no need for a space for swinging the swinging arm around its pivot point, so the space for the swinging arm can be reduced as much as possible and the entire device can be configured compactly, making cleaning easier. By controlling the top brush to move up and down in response to changes in the surface pressure of the top brush at the time of cleaning, the entire top surface of the vehicle body can be cleaned uniformly and evenly with a substantially constant blood pressure.
