In addition, the surface treatment agent tank T ₁ is connected to the second ejector 33 via the surface treatment agent supply pipe 36. Therefore, when the solenoid valve 34 is opened after the water pump P is driven, the pressure water reaches the second ejector 33 via the solenoid valve 34, where the surface treatment agent is applied according to the ejector effect. Since the surface treating agent in the tank T ₁ is sucked through the supply pipe 36, the surface treating agent and the pressure water are mixed to reach the first ejector 29. Thus, when the solenoid valve 30 is changed again, the high pressure air in the air tank A reaches the first ejector 29 via the pressure reducing valve 31 and the solenoid valve 30, and thus the first ejector 29. ), The mixture of the surface treatment agent and the clear water and the high pressure air are mixed to form a bubble-like surface treatment agent, and the surface treatment agent is supplied to the surface treatment agent injection pipe 26 in the form of foam and sprayed from several nozzles 27. .

In the middle of the upper aqueous wax injection pipe 40, the water wax P is connected to the water pump P via the aqueous wax supply pipe 45, the third ejector 46, and the solenoid valve 47. The aqueous wax tank T ₂ is connected to the third ejector via the solenoid valve 48. Therefore, when the positron valves 47 and 48 are changed after the water pump P is driven, the pressure water reaches the ejector 46, where the aqueous wax and the aqueous wax in the aqueous wax tank T ₂ sucked in accordance with the ejector effect and The pressure water is mixed and the mixed liquid is injected from several nozzles 42, 43, and 44.

Operating system of each rotary brush (4), (5), detergent coating device (C), surface treatment agent coating device (W ₁ ), aqueous wax coating device (W ₂ ), rinsing device (R) and drying device (D) The operation of and the traveling operation of the travel frame 1 is controlled by the control device 57 installed on the travel frame (1).

Next, the operation of the embodiment executed using the car wash apparatus having the above-described configuration will be described with reference to FIGS. 3A, 3B to 8A, and 8B.

First, the vehicle V is stopped at a predetermined position between the running rails 2 and 2. As shown in FIG. The gate-type traveling frame 1 stores the first road dashed line as described above by the top rotating brush 4 as described above, while the top blow nozzle 23 is maintained at the raised position at the left end positions of FIGS. 3A and 3B. It descends from (X) to the operating position of the 1st solid line. Then, the top rotary brush rotating pair of side 4 and left and right brushes (5), (5) the top rotary (operation 3a also, the 3b an arrow r ₁ direction) Sikkim and at the same time, the upper and side portions detergent injection pipe (49 ), (50), (50) and the detergent from the fresh water injection pipe 37, respectively, while spraying the gate-type driving frame (1) to the right of the third degree, and the upper rotary brush (4) The vehicle body upper surface of the automobile V is brushed and cleaned by swinging around the horizontal axis 6. On the other hand, the left and right pairs of side rotating brushes 5 and 5 are controlled to open and close following the guide rail 17 to sequentially clean and clean the front, left and right sides and the rear of the vehicle. Then, the detergent or dirt remaining on the surface of the vehicle body is washed with clean water sprayed from the fresh water spray pipe 37 in accordance with the brushing cleaning and flows down. And, such brushing cleaning is conventionally known, but in particular, in the present embodiment, the pair of left and right side rotating brushes 5 and 5 brush the front of the vehicle body, that is, brushing the left and right sides and the rear of the vehicle body. time is in reverse (Figure 3b the arrow direction r ₂₎ to the state.

Thus, when the traveling frame 1 reaches the right end position as indicated by the dashed-dotted line in FIG. 3, the driving stops at the same time, and the spraying of detergent and clear water is stopped to finish the brushing process of the vehicle body. Next, as shown in the solid lines of FIGS. 4A and 4B, the above-described upper surface and each side rotating brush (4), (5), and (5) are in the state where the gate-type traveling frame 1 is in the right end position. the respective rotating (the 4a also, the 4b an arrow r ₂ direction) Sikkim with the surface treatment agent applying device (W ₁₎ while ejecting the foam onto the surface treatment agent from a surface treatment agent injection pipe 26, gate driving frame together (1 ) Is reversed to the left side of FIG. 4, and the foamed surface treatment agent is applied on the vehicle body surface, and the vehicle body surface is reversed from the brushing cleaning described above according to the respective rotary brushes 4, 5, and 5. Shine in order. That is, a foamy surface treatment agent can be applied to the vehicle body surface. Furthermore, in such a mining process, the pair of side rotating brushes 5 and 5 polish the rear surface of the vehicle body, that is, normal rotation when the both sides and the front surface of the vehicle body are polished (Fig. 4B arrow r ₁ direction). ) State.

Therefore, since the surface treatment agent sprayed in this process is in the form of a foam, even a relatively small amount of the surface treatment agent can be evenly applied to the vehicle body surface without falling down immediately after being applied to the vehicle body surface.

4A and 4B, as shown by the dashed line, the gate-type traveling frame 1 stops its running when it reaches the left end position and stops the spraying of the foam surface treatment agent to finish the surface treatment process of the vehicle body. Quit.

Next, as shown in Figs. 5A and 5B, the top and side rotary brushes 4, 5, and 5 are rotated normally with the gate-type traveling frame 1 stopped at the left end position. the 5a also, by first 5b also injects the aqueous wax from the top and side aqueous wax injection pipe 40, 41, 41 in the arrow r direction of the ₁₎ Sikkim and at the same time an aqueous wax applying device (W ₂₎ that Aqueous wax is applied directly onto top and side rotating brushes (4), (5) and (5). Such an application process involves the reaction of a cationic active agent in the applied aqueous wax with an anionic active agent in a surface treatment agent attached to each of the rotary brushes (4), (5) and (5) in the surface treatment process. This time until generation | occurence | production enough, for example, it continues for about 5 second.

When the above-mentioned aqueous wax coating process is finished, clear water is sprayed from the fresh water spray pipe 37 of the rinsing device R while the aqueous wax coating device W ₂ is kept in an operating state, and the running frame 1 6a and 6b are advanced in the right direction. According to this advance, the car body surface coated with the aqueous wax is polished in the same order as in the case of brushing cleaning with the upper surface and each side rotating brush (4), (5) and (5), and at the same time, the rinsing device (R) Excess wax on the body surface flows down into the clear water sprayed from. Moreover, such a pair of side rotary brush (5) In the optical betting process, 5 is a light figure of the front of the vehicle body, and then, that is, the reverse rotation when the bet to the vehicle body both side surfaces and rear light (operation 6b an arrow r ₂ Direction).

Therefore, in the above-described photocoating step, the insoluble aqueous wax component sufficiently generated and retained in the rotating brushes 4, 5, and 5 in the above process, that is, the aqueous wax coating step with the rotating brush, or the photocoating step The insoluble aqueous wax powder produced by the contact reaction of the water-based wax applied on the surface of the vehicle or the surface treatment agent adhered to the surface of the vehicle during the surface treatment process was applied to each part of the body surface by the photoluminescent action of the rotary brushes 4, 5, and 5. It can be applied to and form a thick wax film thereon.

Thus, as shown by the dashed lines 6a and 6b of the gate-type traveling frame 1, the driving of the gate-type traveling frame 1 is stopped and the solenoid valve 48 is closed while reaching the right end position. Then, the spraying of the aqueous wax is stopped to finish the polishing and rinsing process.

When the above-mentioned photo-glossing and rinsing process is completed, as shown in FIGS. 7A and 7B, the top and side rotating brushes 4, 5 and 5 are stopped as the gate type travel frame 1 is stopped at the right end position. continues rotating (the 7a also, the 7b an arrow r ₂ direction), and once again continue the solenoid valve 39, 47 to one changed rinsing device (R) and an aqueous wax applying device of (5) (W ₂ Only the pure water is sprayed to the rotary brushes (4), (5) and (5) from each of the injection pipes (37), (40), and (41) of the nozzle. By modifying (4) and (55), clean water is also injected into the rotary brushes (4), (5) and (5) from the injection pipes (49) and (50) of the detergent coating device (C). Therefore, the water-based wax component adhered to the rotary brush can be immediately washed away by the rotary brushes 4, 5 and 5 by the sprayed clear water. By the way, when cleaning with the rotary brush (4), (5), (5), the injection pipes (37), (49), (50), of all the devices (R), (C), (W ₂ ) described above Instead of jetting clean water from (40) and (41), the solenoid valve 56 of the detergent coating device C is opened, and from the injection pipes 49 and 50 of this detergent coating device C, The detergent is sprayed with clean water from the spray tubes 37, 40 and 41 of the rinse apparatus R and the aqueous wax coating apparatus W ₂ , or the solenoid valve of the detergent coating apparatus C otherwise. By modifying only (55) and (56), all of the solenoid valves (39), (47), and (48) of the rinse device (R) and the aqueous wax applicator (W ₂ ) are changed, and the detergent coating device (C) described above. Only the detergent may be sprayed from the injection pipes 49 and 50 at the same time. Moreover, as said detergent, you may use the thing containing a nonionic active agent and an anionic type active agent.

Continue spraying clean water or detergent for the rotary brushes (4), (5), and (5) for about 10 seconds, and then change all solenoid valves to stop the spray of clear water or detergent, and then rotate the rotary brush (4 ), (5) and (5) are stopped. Then, the upper surface rotating brush 4 is flipped to the upper storage position X as described above, and again, the left and right pair of side rotating brushes 5 and 5 are opened outward to clean the rotating brush. Quit.

Lastly, the gate-type traveling frame 1 located at the right end position in FIGS. 8A and 8B is reversed again, the upper blow nozzle 23 is lowered to an appropriate position, and the blower 24 is driven to drive a pair of side surfaces. When the dry air is blown out simultaneously from the nozzles 22, 22 and the upper blower nozzle 23, dry air is sprayed onto the entire surface of the vehicle body surface after rinsing, thereby blowing water droplets on the vehicle body surface. When the gate type travel frame 1 reaches the left end position, the driving of the gate type travel frame 1 is stopped, and the driving of the blower 24 is stopped to end the drying process of the vehicle body.

The whole process of washing the vehicle body, the surface treatment with the foam-like surface treatment agent, the polishing with the aqueous wax, the rinse, the cleaning of the rotary brush, and the vehicle body drying is completed according to the above.

However, in the surface treatment process, the foam-like surface treatment agent containing an anionic activator is subjected to the brushing action by the rotary brushes (4), (5), and (5) to form a surface treatment agent film on the surface of the vehicle. In the betting process, it is possible to easily carry out the attachment of the aqueous wax containing the cationic system active agent applied to the vehicle body surface to the vehicle body surface. In addition, according to the adhesion of the aqueous wax, since the cationic activator in the wax reacts with the anionic activator in the surface treatment agent, the wax component dissolved in the aqueous wax becomes insoluble until then. 4), (5), and (5) can be rubbed into the car body surface by the photoluminescent action, but there is a slight delay before the two active agents come into contact and produce an insoluble wax component. In the present embodiment, however, the aqueous wax is applied directly to each of the rotary brushes 4, 5, and 5 prior to the polishing step, so that the applied aqueous wax is applied in the previous step, that is, in the surface treatment step. Insoluble wax components can be sufficiently generated and retained in each of the rotating brushes 4, 5, and 5 by reacting with the surface treatment agents attached to the rotating brushes 4, 5, and 5. Since it is possible to move to the photonic process in the state, the vehicle body surface (for example, symbol (B) in FIG. 6B) which is polished in accordance with the rotary brushes (4), (5), and (5) at the beginning of the photonic process. The surface of the bonnet (shown in front of the bonnet) can be sufficiently rubbed with the above insoluble wax component at the beginning of the photorefining process to form a thick wax coating thereon. Even if it is shortened, it does not interfere.

Furthermore, in the above embodiment, the aqueous wax was applied directly to all of the upper surface rotating brush 4 and the side rotating brushes 5 and 5 prior to the polishing process. Instead, the aqueous wax was applied to one of the rotating brushes. Directly apply only to (4) or (5) and (5) so that the other rotating brush scatters the aqueous wax rather than the rotating brush on one side, and reacts it with the surface treatment agent of the rotating brush on the other side so that the light The betting process may be performed.

In addition, during the cleaning process of the rotating brush leading to the polishing and rinsing process, clean water sprayed from each spray pipe, or water-based wax components attached to the rotating brushes (4), (5), and (5) according to the detergent immediately Since it can be washed and flowed down, the aqueous wax components do not accumulate and accumulate in these brushes 4, 5, and 5, and accordingly, the difference is caused during the brushing cleaning process performed prior to the above-described polishing process. There is no fear that dirt from the body surface may stick to the rotating brushes (4), (5) and (5). Therefore, the rotating brushes (4), (5), and (5) can be kept clear and clean, and there is no worry of sticking the soiled water-based wax component to the body surface when it is polished, so a good luminous effect can be expected. In addition, the aqueous wax component is concentrated in the rotary brushes 4, 5, and 5, so that the aqueous wax component can be washed away by a simple spray of washing water before being firmly adhered to it, thereby eliminating the aqueous wax component. You can run the task simply and quickly.

Further, in the embodiment, the surface treatment step may be replaced with a water cleaning step in which only clean water is sprayed on the vehicle body surface. In addition, as described above, the water cleaning step is performed after the brushing cleaning step is completed, and as shown in the solid lines of FIGS. 9A and 9B, the rotary brushes 4 are in the state where the gate-type traveling frame 1 is in the right end position. , (5), (5) are stopped and the top rotating brush (4) is popped up to the upper storing position (X) to open the left and right pair of side rotating brushes (5) and (5) outwards, and then the gate type driving As the frame 1 is retracted to the left and at the same time, clean water is sprayed from the fresh water spray pipe 37 of the rinse device R toward the vehicle body, thereby washing and brushing the vehicle body surface with water pressure of clear water. After the process is completed, the detergent or dirt remaining on the surface of the vehicle body can be strongly washed off. When the gate type travel frame 1 reaches the left end position, the running of the travel frame 1 is stopped to stop the spray of clear water, and the upper rotating brush 4 is lowered from the upper storage position X to the left and right sides. The rotary brushes 5 and 5 are closed to finish the above-described water washing step.

In addition, it has the function of applying descaling agent to the surface of the car body and using the rotary brush to remove the scale and deteriorated wax on the car body surface. Since the aqueous wax component adhered to the rotating brush in the polishing step of the previous car wash operation can also be removed from the rotating brush in the removal step such as the above-mentioned scale, it is rotated every time the polishing step is finished after the removal step. It is not necessary to carry out the spraying process of the washing water to the brush one by one and control not to execute the washing water spraying process for the rotating brush while performing the polishing process for a certain number of cars (for example, 20 cars). Also good.

Further, in the above-described embodiment, the rotating brush is rotated during the spraying of the washing water with respect to the rotating brush after the polishing process, but instead, the washing force is sprayed by spraying the washing water in a state where the rotating brush is stopped. Only the residual aqueous wax powder of the brush may be washed away.

As described above, according to the present invention, the vehicle is mounted on the gate-type driving frame so that the vehicle can be moved forward and backward, thereby brushing and cleaning the body surface of the vehicle, surface treatment with a foam-like surface treatment agent, and polishing with water-based wax. Because the four processes of rinsing and drying can be performed without sequential steps, washing and subsequent waxing work can be carried out very efficiently with two round trips in the case of a gated driving frame. In particular, the surface treatment step by the foam-like surface treatment agent is economical because it is not wasteful because the surface treatment agent can be evenly applied to the vehicle body surface in a relatively small amount.
