Description

[Detailed description of the invention] The present invention relates to a scale removal device for a vehicle.

In the present invention, "limescale" originally refers to inorganic substances such as calcium dissolved in water that adhere to the painted surface of a vehicle, seep through, and appear as darkening.
This is a broad term that includes dirt on the vehicle surface due to exhaust gas oil smoke, soot, aged wax, etc.

Conventionally, car wash machines with the functions of washing and waxing vehicles have been realized, but car wash machines with the function of removing limescale have not been realized, and the limescale has been removed by hand. Therefore, a great deal of effort is required to remove limescale, and it is desired to realize a scale removal apparatus that can mechanically remove limescale from vehicles.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a vehicle water scale removal device that can mechanically remove water scale from a vehicle with almost no manual effort. .

In order to achieve this object, the device of the present invention has a gate-type traveling frame that can run in the front and back directions of the vehicle, straddling the vehicle whose surface is to be cleaned of water scale, and a device for applying plastic coating to the surface of the vehicle. A rotating brush device is provided, and at least one of the front and rear sides of the rotating brush device along the traveling direction is provided with a scale removing agent spraying device.

The portal traveling frame 2 is equipped with a rotating brush device 7 including an upper rotating brush 5 and a pair of side rotating brushes 6. The upper surface rotating swing 5 is swingably supported via a swing arm 9 on a horizontal shaft 8 that is rotatably supported on the gate-shaped traveling frame 2 . The swinging arm 9 is provided with a prime mover 10 at its upper part, and the top rotary brush 5 is rotationally driven from the prime mover 10 via a transmission mechanism (7) inside the swinging arm 9. A Sugerocket 11 is fixed to the , and an intermediate shaft 12 is rotatably supported on the gate-shaped traveling frame 2 below the horizontal shaft 8 , and another sprocket 13 is fixed to the intermediate shaft 12 . An endless chino 14 is suspended between both sprockets 11 and 12, and this chino 14
The mounting bracket 15 fixed in the middle of the gate type running)l/
- A piston rod 17 of an air cylinder 16 whose lower end is supported by the arm 2 is connected. Therefore, if the air cylinder 6 is driven to contract, the upper rotating brush 5 can be held in the upper retracted position as shown by the two-dot chain line. Furthermore, when the air cylinder 16 is inactive, the upper rotating brush 5 can freely swing back and forth around the portal-shaped traveling frame 20 about the horizontal axis 8.

The rotation shafts 18 of the pair of side rotating brushes 6 are held in a holding cylinder 19, and the holding cylinder 19 is fixed to the movable frame 20 with its axis being vertical. The moving frame 20 is slidably engaged with a guide rail 21 horizontally suspended on the portal traveling frame 2, and the support shaft 22 of the guide rail 21 is rotatably supported by the portal traveling frame 2. Ru. Therefore, the guide rail 21,

A prime mover 23 is supported on the movable frame 20, and a sprocket 2 fixed to the output shaft of the prime mover 23 is supported on the movable frame 20.
4, and a sprocket 25 fixed to the end of the rotating shaft 18.
An endless chino 26 is suspended between the two, and the side rotary brush 6 is rotationally driven by the prime mover 23.

The gate-shaped traveling frame 2 is provided with scale remover spraying devices 2T, 2 before and after the rotating brush device 7 along the traveling direction 4 thereof.
8 are provided respectively, and their scale remover spraying devices 2
Rinse water spray devices 29 and 30 are provided inside the 7 and 28, respectively.

Next, the structure of such scale remover spraying device 27, 28 and rinsing water injection device 28, 30 is shown in FIG.
．． I will explain. The scale remover dispersing device 27 , 28 is connected to a gantry-shaped supply header 3 supported inside the gantry-shaped traveling frame 2 .
1.32 with a plurality of spray nozzles 33.34 directed toward a vehicle (not shown). These spray nozzles 33, 34 are respectively attached to supply headers 31, 32 so as to be able to adjust their spraying directions, and their opening areas are set to be relatively large. Both rinse water spray devices 29.30 are constructed by mounting a plurality of spray nozzles 37.38 towards the vehicle on a gantry feed ladder 35.36 supported inside the gantry running frame 2. .

The scale remover spraying device 27.28 includes a water supply pump P.
1 air source A and scale remover storage tank T are connected to each other. That is, the water supply pump P has a first solenoid valve S.
The IN first eggoctor E is connected in this order, and the air source A
A twelfth solenoid valve S2, a pressure reducing valve C, and a second ejector E2 are connected in this order, and a first ejector E is connected at right angles to the second J-lid E2. Further, a scale remover storage tank T is connected at right angles to the first ejector E1.

Further, the second ejector E2 supplies the descaling agent to one of the scale remover spraying devices 27 via the third solenoid valve S.
and is connected to the upper center of the ladder 32 via a fourth solenoid valve S to the supply in the other descaling agent spraying device 28 .

A water pump P is also connected to the rinsing water spray device 29.30 in the upper center of the ladder 35.36 via fifth and sixth solenoid valves S6, S6, respectively, to their supply.

The scale remover stored in the scale remover storage tank T is strongly alkaline and has a pH of 14 in its undiluted form.
The one adjusted to about 2 to 14 is used. As a result of experiments conducted by the present inventor, water scale cannot be removed using conventional detergents with a pH of about 8 to 10, and the above-mentioned pi 12 to 1
This is based on the discovery that water scale can be lifted and removed from the painted surface of a vehicle using a water scale remover of about 4.

The operation of the scale remover spraying device 27, 28 and the rinsing water spraying device 29, 30, the operation of the rotating brush device 7, and the traveling operation of the gantry-type traveling frame 20 are controlled by a control panel 39 provided on the gantry-type traveling frame 2. (See Figure 1).

Next, the operation of this embodiment will be explained with reference to FIGS. 3 and 6. In FIGS. 3 to 6, the upper part (a) shows a simplified side view, and the lower part (b ) shows the simplified plane.

First, in order to remove limescale from the vehicle V, the outer surface of the vehicle V is washed by hand with a detergent or by a scrubbing method using a car washer (not shown), and then dried.

Next, a start key (not shown) on the control panel 37 is depressed. As a result, the gate-shaped traveling frame 2 moves back and forth as shown by the arrows in FIG. Along with this, the first, second,
The third solenoid valves s, 'i S2, S3 are opened, and the fourth, fifth, and sixth solenoid valves S4, S5, and S6 are kept closed. Therefore, the water from the water pump P sucks up the descaling agent in the first ejector E and reaches the second ejector E2, where it is foamed by the air from the air source A. The foamy scale remover reaches the supply header 31 of one of the scale remover spraying devices 27, and is sprayed toward the vehicle V from each spraying nozzle 33 in foamy form.

At this time, since the opening area of the spray nozzle 33 is set to be relatively large, the bubbles of the scale remover adhere to the surface of the vehicle V without being crushed. Spraying the scale remover in the form of foam in this way prevents the scale remover sprayed on the surface of the vehicle V from immediately flowing down, and prevents the scale remover from flowing down immediately.
This is to ensure the reaction time necessary for the material to lift up from the surface and to obtain a uniformly treated surface. Also, according to experiments, by spraying it in foam form, compared to simply spraying it in liquid form,
It was possible to obtain an excellent limescale removal effect. Furthermore, by brushing V with the rotating brush device B, the same effect as manual scrubbing work is performed, and the descaling agent sprayed on the surface of the vehicle V is evenly distributed over the entire surface of the vehicle V. Dress up.

Next, the gate-shaped traveling frame 2 is moved back as shown by the arrow in FIG. 4, and the first, second, and fourth solenoid valves S, ,
S21.54 is opened, and the third, fifth, and sixth solenoid valves S3
, S6, and S6 are closed. As a result, the scale remover is sprayed in the form of foam from the other scale remover spraying device 28 toward the vehicle V, and furthermore, brushing by the rotary brush device γ is performed in the same manner as the brushing described above.

When the gate-shaped traveling frame 2 returns to the scale removal start position, the process is paused for, for example, 5 to 10 minutes.

As a result, the limescale attached to the surface of the vehicle V is lifted off the surface of the vehicle V by the limescale remover. Also, during this time, parts that are difficult to be brushed with by the rotary brush device 7 are manually touched up.

After the pause of about 5 to 10 minutes, a rinse start key (not shown) on the control panel 39 is pressed, and the gate-shaped traveling frame 2 is moved back and forth as shown by the arrows in FIG. At the same time, the fifth and sixth solenoid valves S3 and S6 are opened, and the first
~The fourth solenoid valves S and ~S4 are closed. Therefore, water is sprayed toward the vehicle V from both rinsing water spray devices 29 and 30, and the rotating brush device 7 performs a plashing operation. As a result, the floating scale and scale remover are washed from the surface of the vehicle V. At this time, the hole diameter of the spray nozzle 37.38 provided in the supply header 35.36 of each rinse water spray device 29.30 is made small, and the spray nozzle 37.3
By increasing the number of parts 8, water can be sprayed evenly over the surface of the vehicle (2).

The water spray from one of the rinsing water spray devices 30 is such that some of the water scales, etc., which have been removed by the plasong of the rotary brush device 7, are applied to the surface of the vehicle (2) by the centrifugal force of each of the rotary brushes and the brushes 5.6. It will stick to your skin, so you need to wash it off.

Furthermore, as shown in FIG.
Only R+ 86 is opened, and the other solenoid valves 81 to S4 are closed. As a result, water is sprayed from both rinsing water spray devices 29 and 30, and the residue left in the rinsing step 1 shown in FIG. 5 is washed away. At this time, the scale remover is not left on the surface of the vehicle V and the number of brush songs is large, so the rotary brush device 7 remains inactive to avoid damaging the painted surface of the vehicle V. do.

After the scale removal process is completed, the car is waxed manually or by another car washing machine, and then dried to complete the entire process.

In the above embodiment, the scale remover spraying devices 27 and 28 were provided before and after the rotating brush device 70, but the scale remover spraying device may be provided on either one.

As described above, the device of the present invention has a rotating brush device for brushing the surface of a vehicle, which is mounted on a gate-shaped traveling frame that can run in the front and rear directions of the vehicle, straddling the vehicle whose surface is to be cleaned of water scale. At the same time, a scale remover spraying device is installed at least on one side of the front and rear of the rotating brush device along the running direction, making it possible to mechanically remove scale remover from the vehicle without having to do it manually. The effort required for this is significantly reduced.
