DETAILED DESCRIPTION OF THE INVENTION A. Object of the Invention (1) Industrial Application Field The present invention relates to a car washing method using a car washing device having a gate-shaped traveling frame.

(2) Prior Art Cleaning in which a cleaning device provided on the gate-type traveling frame is operated to clean the body surface of the vehicle while a gate-type traveling frame that can straddle the vehicle is reciprocated in the longitudinal direction of the vehicle. a wax application step in which wax is applied to the vehicle body surface by operating a wax application device provided on the same gate type running frame, and a drying step in which a drying device provided in the same gate type traveling frame is operated to dry the vehicle body surface. A car washing method in which the steps are sequentially performed is conventionally known.

(3) Problems to be Solved by the Invention When carrying out the above conventional method, the vehicle body painted surface is in good condition, or a long time has elapsed since the last waxing, and the wax effect still remains. When applying wax to existing vehicles, a sufficient wax effect can be obtained without performing the waxing process carefully for a long time. When applying wax, a sufficient wax effect cannot be obtained unless wax spraying is continued for a long time.

Therefore, depending on the various conditions of the car body surface, such as how dirty it is, whether the paint is good or not, how much wax effect remains, etc.
It is conceivable to individually change and control the wax injection flow rate and injection speed from the wax applicator, but in that case, the structure of the wax applicator would become more complicated, and its control would be troublesome, increasing costs. There is a problem with bulk.

The present invention has been proposed in view of the above, and an object of the present invention is to provide a car washing method that can solve the above problems of conventional methods.

B. Structure of the Invention (1) Means for Solving the Problems And in order to achieve the above object, the present invention provides a method for reciprocating the gate-type traveling frame that can straddle a vehicle in the longitudinal direction of the vehicle. a cleaning step of activating a cleaning device provided on the running frame to clean the vehicle body surface; a wax application step of activating a wax applicator provided on the same-type running frame to apply wax to the vehicle body surface; In the car washing method, a drying step of drying the vehicle body surface by activating a drying device provided on the molded traveling frame is sequentially performed, wherein at least a part of the traveling section of the gate-shaped traveling frame is dried during the waxing step. Multiple control programs with different running speeds are set in advance, and one of these control programs
The present invention is characterized in that one of the two can be arbitrarily selected by selectively operating a select switch depending on the condition of the vehicle body surface before wax application.

(2) Effect According to the above configuration, at least a portion of the gate-shaped traveling frame is removed during the waxing process depending on various conditions of the vehicle body surface, such as the degree of dirt, the degree of damage to the painted surface, the degree of residual wax effect, etc. Since the traveling speed of the traveling section can be arbitrarily changed and controlled, the contents of the waxing process can be changed as appropriate depending on the above-mentioned various conditions of the vehicle body surface. For example, when applying wax to a vehicle whose painted surface is in good condition, or to a vehicle where it has been a long time since the last waxing and the wax effect still remains, in other words, waxing is applied in a short period of time. If an effect can be obtained, the waxing process can be stopped early to improve work efficiency. On the other hand, when applying wax to a vehicle whose painted surface is in poor condition or where the wax effect has disappeared, a sufficient wax effect can be obtained by carrying out the waxing process for a long time.

Furthermore, in order to change the content of the wax process depending on the above-mentioned various conditions of the vehicle body surface, there is no need to specially change and control the jetting flow rate and jetting speed of wax from the wax applicator.

This select switch includes two types of first car wash program selection switches _S1 , which wash the car body when the gate-type traveling frame 1 goes out and dry the car body when it goes back; The car body is brushed and washed on the outbound trip, polished while applying a base wax to the car body on the first go-around, polished while applying finishing wax to the car body on the second go-around, and polished on the second go-around. _The first car wash program selection switch _S1 includes a low speed switch 36 that causes the gate-shaped traveling frame 1 to reciprocate at low speed;
and a high-speed switch 37 for reciprocating the gate-shaped traveling frame 1 at high speed, and the switch _S2 for selecting the second car wash program is used only during the second reciprocating of the gate-shaped traveling frame 1 (when applying finishing wax). A low-speed switch 38 that causes the frame to run at high speed and at low speed at other times; a high-speed switch 39 that causes the gate-shaped traveling frame 1 to run at low speed only during the second go-around (dry time) and at high speed at other times; Both of the second reciprocating rows include a busy switch 40 that causes the gate-shaped traveling frame 1 to travel at high speed.

The second car wash program selection switch
The low speed switch 38 and high speed switch 39 of _S2 constitute the select switch of the present invention, and when these switches 38 and 39 are selected, the cleaning step of the present invention is performed during the first forward movement. The wax application step of the present invention is performed during the first and second return trips, and the drying step of the present invention is performed during the second return trip.

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

First, when an appropriate car wash mode is selected using the switches 36 to 40 and the start button 33 is pressed, the driving motor 9 is started and the gate-shaped traveling frame 1 is moved to the first wash mode for the vehicle parked at the car wash position. Start traveling in the direction shown. When only washing and drying the vehicle, press either of the switches 26 and 37 that make up the first car wash program selection switch _S1 . Washing water containing detergent is sprayed onto the car body surface from 30, and the top rotating brush 4 and side rotating brushes 5, 5 are used to brush the car body surface while cleaning, and fresh water is sprayed from the first rinsing water injection pipe 27 to perform rinsing. During the go-around, pressurized air is blown onto the surface of the vehicle body from the top blow nozzle 22 and the side blow nozzles 21, 21 to dry the surface.
In this case, when the vehicle is very dirty, by selecting the low speed switch 36, the gate type traveling frame 1 can be made to travel back and forth at low speed to cleanly remove the dirt from the vehicle body surface. , the high-speed switch 37 is selected to cause the gate-shaped traveling frame 1 to reciprocate at high speed, thereby shortening the car washing time.

Furthermore, when washing, waxing, and drying the vehicle, press any of the second car wash program selection switches 38, 39, and 40.
During the first outbound movement of the gate-shaped traveling frame 1, detergent-containing washing water is injected onto the vehicle body surface from the detergent injection pipe 30, and the vehicle body surface is brushed and cleaned by the top rotating brush 4 and the side rotating brushes 5, 5. Rinsing is performed by spraying fresh water from the rinsing water injection pipe 27,
During the first go-around, polishing is performed using the top rotating brush 4 and the side rotating brushes 5, 5 while injecting the base wax onto the car body surface from the base wax injection pipe 25. During the second go-around, polishing is performed using the top rotating brush 4 and the side rotating brushes 5, 5.
Finishing wax is applied to the car body surface from step 9 and polished by the top rotating brush 4 and side rotating brushes 5, 5, and the second rinsing water injection pipe 28
The surface of the car body is rinsed by spraying fresh water from the top, and finally, during the second go-around, pressure air from the top air blowing nozzle 22 and the side air blowing nozzles 21, 21 is blown onto the car body surface to dry the surface. It's summery. In this case, for vehicles with heavily soiled bodies or vehicles with almost no residual wax effect,
The low speed switch 38 is selected to run the gate type traveling frame 1 at low speed except for the finishing wax application process during the second outbound movement, and the vehicle body surface is sufficiently cleaned and waxed. If the painted surface is in good condition, or if it has been a long time since the last waxing and the waxing effect still remains, select high speed switch 39. The gate type traveling frame 1 is run at high speed except for the drying process, and when the number of cars being washed is busy, the busy switch 4 is activated.
By selecting 0, the gate-shaped traveling frame 1 can be made to travel at high speed in all the car washing steps during the first and second reciprocations, thereby shortening the car washing time.

C. Effects of the Invention As described above, according to the present invention, while the gate-type traveling frame capable of straddling a vehicle is reciprocated in the longitudinal direction of the vehicle, the cleaning device provided on the gate-type traveling frame is operated. A cleaning process for cleaning the body surface of the vehicle, a wax application process for applying wax to the vehicle body surface by operating a wax coating device installed on the same-gate type running frame, and a wax application process for activating the drying device installed on the same-type running frame. In the car washing method, a drying step of drying a vehicle body surface is sequentially performed, and a plurality of control programs are preset in which the traveling speed of at least a part of the traveling section of the gate-shaped traveling frame during the waxing step is different. By selectively operating the select switch, one of these control programs can be arbitrarily selected according to the condition of the car body surface before wax application, so that various conditions of the car body surface, such as how dirty it is, Depending on the degree of damage to the painted surface, the degree of remaining wax effect, etc., the traveling speed of at least a part of the traveling section of the gate type traveling frame during the waxing process can be arbitrarily changed and controlled. The content of the waxing process can be changed as appropriate depending on the various conditions mentioned above.For example, if the painted surface of the vehicle is in good condition, or if it has not been a long time since the last waxing, the waxing effect still remains. When applying wax to a vehicle that is in a bad condition, i.e., when the wax effect can be obtained in a short period of time, it is recommended to stop the waxing process early to improve work efficiency, and when applying wax to a vehicle that is in poor condition. When applying wax to a vehicle or a vehicle in which the wax effect has disappeared, a sufficient wax effect can be obtained by performing the waxing process for a long time. Moreover, in order to change the content of the wax process according to the above-mentioned various conditions of the car body surface, there is no need to specially change and control the wax injection flow rate and injection speed from the wax applicator, and the traveling speed of the gate-type traveling frame Since it is sufficient to simply change and control the wax applicator, the structure of the wax applicator can be simplified to that extent, and its control can also be simplified, which can greatly contribute to cost reduction.
