Furthermore, when the wheel b or the feeler c is not in contact with the vehicle d, air is not sent to the lifting cylinder f by the mechanical valve e, and the force to wind up the chain g is lost, and the air nozzle i is lowered by its own weight. do.

In this way, when the wheel b or the feeler c runs along the shape of the top surface of the vehicle d, the mechanical valve e is switched and the air nozzle 1 can repeatedly move up and down.

[Problem to be solved by the invention]

As mentioned above, when wheel b or feeler c runs while touching the top surface of car d, the part of car d that comes into contact with wheel b or feeler c is not dry, and water droplets remain in a line. There is a point.

The present invention provides a shape-tracing mechanism for an air nozzle that can move to follow the shape of a vehicle without contacting the vehicle, thereby uniformly discharging air from the air nozzle toward the vehicle. , which solves the above-mentioned conventional problems.

[Means to solve the problem]

According to the present invention, the above problem can be solved by providing a car wash machine in which an air nozzle that blows out air for drying a car is connected to an air cylinder that is controlled with a tracing mechanism that follows the shape of the roof of the car. The copying mechanism consists of a blade that rotates when it receives the wind pressure of the air discharged from the air nozzle and reversed when it hits the roof of the car, and an air nozzle for lifting and lowering that is activated by the rotation of the blade. This problem is solved by comprising a switching control element for the air cylinder.

〔Example〕

The present invention will be explained in detail with reference to embodiments shown in FIGS. 1 to 4.

As shown in FIG. 1, in order to form a link mechanism 9, the base ends of two upper and lower links 10 that are parallel to each other are attached to a vertical support rod 3 that hangs down from the upper surface of the car wash machine 4.
The link 10 is pivotally connected to a bracket 12 fixed to the link 5 with a pivot 11, and a vertical rod 13 is attached to the tip of the link 10.
are pivotally connected with a pivot 14.

The tip of the piston rod of the horizontal air cylinder 2 serving as a driving source for lifting and lowering, whose base is pivoted on the upper surface of the car wash machine 4 with a pivot 36, and the stopper 15 provided at an appropriate position on the upper link 10. A chain 16 is stretched across.

Reference numeral 1 denotes an air nozzle, which is fixed to the lower end of the vertical rod 13 at an angle of 0 to 7 degrees forward with respect to the vertical direction.

A support member 18 is fixed to the lower front surface of the air nozzle 1, and a wheel 19 and a shaft portion 21 of a feeler 20 having a U-shaped side surface are attached via a pivot 22 to this support member 18.

As a switching control element for the air cylinder 2, the upper end of a known mechanical valve 6 is fixed to a support member 18.

As shown in Figs. 2 to 4, the mechanical valve 6
A support arm 26 facing downward is fixed to the front surface of the support arm 26, and the front end of a lever 27 facing rearward is pivotally connected to the lower end of the support arm 26 with a shaft 28.

A ring-shaped speed controller 30 is pivotally attached to the rear end of the lever 27 with a shaft 29 .
It fits into a recessed arc-shaped surface 24 on the upper surface of the holder. At this time, the pusher 31 protruding from the upper surface of the central part of the lever 27 is connected to the valve 17 of the mechanical valve 6.
It is in contact with the bottom surface of the holder without pressing it.

The upper surface of the front end of a horizontal rotating rod 33 whose rear end is pivotally supported by a shaft 34 is in contact with the lower surface of the shaft 29 of the speed controller 30. The upper end of a blade 8 that is perpendicular to the running direction of the car wash machine 4 on the front surface of the air nozzle 1 is fixed to the rear end of the rotation rod 33 .

A non-contact copying mechanism 3 is formed by the mechanical valve 6 including the blade 8, the rotating rod 33, the lever 27, the pusher 31, and the valve 17.

As shown in FIG. 2, when the air discharged from the air nozzle 1 does not hit the vehicle 5, the pusher 31 does not press the valve 17 of the mechanical valve 6, and the air is not sent to the lifting cylinder 2. Therefore, the air nozzle 1 descends due to its own weight.

On the other hand, the air discharged from air nozzle 1 is
As shown in FIG. 3, when the air nozzle 1 hits the upper surface of the vehicle 5 located below and is reversed forward and upward, the blade 8 is rotated forward by the wind force, and the rotation rod 33, The valve 17 is pushed up via the shaft 29, the lever 27, and the pusher 31, and air is sent to the lifting cylinder 2, and the air nozzle 1
will rise.

The mechanical valve 6 is thus expediently connected to the lifting cylinder 2.

23 in FIG. 1 indicates a pivot 32 attached to the support member 25.
The sprocket 37 attached with a holder is a duct connected to the air nozzle 1.

Next, the operation of the above embodiment will be explained.

Even if high-speed air is discharged from the air nozzle 1 by the blower, if this air does not hit the car 5, it will be discharged downward and will not hit the blade 8, as shown in FIG. do not have.

Therefore, as shown in FIG. 2, the vane 8 does not move, the valve 17 is not pressed, and no air is sent to the lifting cylinder 2.

Therefore, the chain 16 is not hoisted up, and the air nozzle 1 is lowered by its own weight via the link mechanism 9.

The car wash machine 4 runs in the direction of the arrow in FIG. 1, and the air from the air nozzle 1 flows as shown in FIG.
When it hits the top of the car 5, the blade 8 rotates forward, the valve 17 is pushed up, and the mechanical valve 6 is switched.

As a result, air is sent to the lifting cylinder 2, the chain 16 is hoisted up, the link mechanism 9 is activated, and the air nozzle 1 rises from the chain line position in FIG. 20 leaves the car 5.

In this way, the wheel 19 or the feeler 20
The air nozzle 1 moves along the shape of the car without contacting the car 5, and the presser 31 presses the valve 17 of the mechanical valve 6.
The air nozzle 1 is raised and the presser 3
1 no longer presses the valve 17, the air nozzle 1
While repeating the operation of lowering the vehicle 5, the vehicle follows the shape of the top surface of the vehicle 5.

The wheels 19 and the feeler 20 are used to carry out drying work in the conventional manner in the event that the non-contact copying mechanism 3 breaks down, and are known per se. Detailed explanation will be omitted.

Next, we will explain how to dry water droplets that adhere to a car during a car wash.

When the car wash machine 4 is run forward (in the direction of the arrow in FIG. 1), the wheels 19 or the feeler 20
The air nozzle 1 moves without contacting the
Air is discharged toward the automobile 5 while following the shape of the roof of the automobile 5.

Since the drying air from the air nozzle 1 is at high speed, it is evenly discharged, blowing away water droplets attached to the car during car washing and drying the car.

In this way, the copying mechanism 3 moves while following the shape of the automobile 5 without contacting it, and evenly discharges air from the air nozzle 1, so that water droplets are not left in a linear shape as in the conventional case. It does not leave a sticky feeling and provides excellent drying effects.

In addition, since the speed controller 30 of the mechanical valve 6 moves up and down while contacting the arcuate surface 24 of the shaft portion 21 of the feeler 20, the copying mechanism 3
The vertical movement speed of the copying mechanism 3 and the air nozzle 1 to which it is attached can be smoothly adjusted by adjusting the speed of the vertical movement and by switching the air using the mechanical valve 6. can do.

[Effects of the Invention] According to the present invention, the switching control element (for example, a mechanical valve) for the air cylinder for raising and lowering the air nozzle is actuated by the rotation of the blade due to the force of the wind discharged from the air nozzle and hitting the vehicle. In addition, if the wind discharged from the air nozzle does not hit the car and is discharged downward, or if the wind force is weak, the switching control element will not operate, so air will not be sent to the air cylinder, and the air will not be sent to the air cylinder. The nozzle descends due to its own weight.

In this way, the automatic switching of the switching control element by the force of the wind moves the tracing mechanism up and down, causing the air nozzle to follow the shape of the car, and directing the air from the air nozzle toward the car. By discharging it evenly, you can blow off water droplets that adhere to the car during car washing and dry it.

Therefore, the conventional disadvantage that when the copying mechanism comes into contact with the automobile, drying of this area becomes difficult and water droplets remain in a linear shape is eliminated.
Also, there is no risk of damaging the car.
