(3) Problems to be Solved by the Invention Generally, in automobiles, in order to obtain a good field of view, it is required that the windshield and the rear glass are dried particularly carefully. Further, it is known that the effect of the drying treatment is improved by performing the drying treatment a plurality of times.

However, in the above-described conventional vehicle body drying device, it is necessary to cause the traveling frame to travel many times in order to perform the drying process a plurality of times. Therefore, there has been a problem that the drying process takes a long time.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a drying device for an automobile body capable of performing a sufficient drying process on a windshield or a rear glass without requiring a long time for the drying process. To do.

B. Configuration of the Invention (1) Means for Solving the Problems In order to achieve the above-mentioned object, a drying device for an automobile body of the present invention includes an upper surface drying nozzle capable of moving up and down, and the upper surface drying nozzle in a traveling frame. An elevating and lowering drive device for elevating and lowering, the reciprocating traveling of the traveling frame by a prime mover,
In a vehicle body drying apparatus in which the upper surface drying nozzle is moved up and down so as to follow the shape of the upper surface of the vehicle body, a vehicle position detection means for detecting a traveling position of the traveling frame and a vehicle body detection for detecting the vehicle body. Means, a determining means for determining whether the inclination angle of the upper surface of the automobile body is a predetermined value or more based on the output signals of the traveling position detecting means and the vehicle body detecting means, and the outputs of the traveling position detecting means and the determining means. A motor control means for controlling the rotation direction of the motor on the basis of a signal; and an elevating control means for controlling the elevating drive device according to the output signals of the traveling position detecting means and the discriminating means. According to the above, the traveling direction of the traveling frame and the elevation of the upper surface drying nozzle are controlled.

As the vehicle body detecting means, an upper surface car wash brush position detecting means for detecting an ascending / descending position of an upper surface car wash brush provided on the traveling frame so as to be capable of ascending / descending, or provided in a vertical direction of a side surface of the traveling frame facing the automobile Multiple sensors or the like can be used. That is, anything having a function of detecting the height of the upper surface of the vehicle body of the automobile may be used.

Further, when an ultrasonic wave transmitter / receiver is used as the vehicle body detection means and an ultrasonic wave reception signal is not obtained as the determination means, it is determined that the inclination angle of the upper surface of the vehicle body is equal to or greater than a predetermined value. Means can be used.

(2) Operation The vehicle body drying apparatus according to the present invention having the above-described configuration is provided with an upper surface drying nozzle on a traveling frame, and a prime mover for reciprocating the traveling frame, and an elevating / lowering device for elevating the upper surface drying nozzle. It has and. Therefore, the upper surface drying nozzle is moved up and down as the traveling frame travels, so that the upper surface of the vehicle body and the upper surface drying nozzle have a gap suitable for the drying processing, and the upper surface of the vehicle body is dried.

At that time, the traveling position detecting means outputs a signal relating to the traveling position as the traveling frame travels. Also, a vehicle body detecting means for detecting the vehicle body, and a discriminating means for discriminating whether the inclination angle of the upper surface of the vehicle body is a predetermined value or more based on the output signal of the traveling position detecting means and the output signal of the vehicle body detecting means. Is equipped with. Therefore, the traveling position of the traveling frame in which the inclination angle of the upper surface of the automobile body is a predetermined value or more is discriminated from the output signal of the discrimination means. Then, a prime mover control means for controlling the rotation direction of the prime mover based on the output signals of the traveling position detecting means and the discriminating means, and a lifting control for controlling the lifting drive device by the output signals of the traveling position detecting means and the discriminating means. And means. Therefore, the traveling direction of the traveling frame and the elevation of the upper surface drying nozzle are controlled according to the inclination angle of the upper surface of the automobile body. Therefore, after performing a drying process on a portion where the inclination angle of the upper surface of the automobile body is equal to or greater than a predetermined value, the upper surface drying nozzle is raised and the traveling frame is returned to a traveling position where the inclination angle exceeds a prescribed value,
By moving the upper surface drying nozzle up and down again as the traveling frame travels, the portion where the inclination angle of the upper surface of the automobile body is a predetermined value or more is dried.

Further, when the upper surface car wash brush position detecting means for detecting the ascending / descending position of the upper surface car wash brush provided on the traveling frame so as to be able to move up and down is used as the detection means, the upper surface car wash brush is in contact with the upper surface of the vehicle body. Therefore, the top surface car wash brush position detecting means outputs a signal corresponding to the height of the top surface of the vehicle body of the automobile, that is, the vehicle height. Therefore, the determining means calculates the inclination angle of the upper surface of the automobile body by obtaining the change in the vehicle height with respect to the traveling distance based on this signal and the output signal of the traveling position detecting means, and a predetermined predetermined value is calculated. By comparing with the value, it is possible to determine whether the inclination angle of the upper surface of the automobile body is equal to or larger than a predetermined value.

Also, when a plurality of sensors provided in the up and down direction of the side surface of the traveling frame facing the automobile are used as the vehicle body detecting means, the output signal of the sensors is a signal corresponding to the vehicle height. The discrimination is performed by the discriminating means in the same manner as when the brush position detecting means is used.

Furthermore, when an ultrasonic wave transmitter / receiver is used as the vehicle body detection means, the transmitted ultrasonic wave is reflected on the upper surface of the automobile body, so that the inclination angle is equal to or greater than a predetermined value,
The reflected ultrasonic waves are no longer received. Therefore, the determination means can determine that the inclination angle of the upper surface of the vehicle body is equal to or greater than a predetermined value when the ultrasonic reception signal is not obtained.

Next, the operation of the embodiment of the present invention having the above configuration will be described.

FIG. 7 is a diagram showing the brushing process when the traveling frame 1 is moving forward, FIG. 8 is a flowchart showing the operation of the control means 60 in that case, and FIG. 9 is a principle of setting the up-and-down position of the upper surface drying nozzle 2. It is a figure.

In FIG. 7, when the traveling frame 1 is at the position (1a) and the upper surface car wash brush 5 is at the upper limit position (5a), when the reciprocating signal generating means D ₈ outputs a signal indicating the going, the control is performed. The means 60 operates based on the flowchart of FIG. In step S ₁ , it is determined whether or not the brushing process is performed. And if the brushing process
Proceeds to S _3, performs other processing proceeds to step S ₂ otherwise. In step S _3, the controller of the storage cylinder 39
By operating 65, the piston rod 40 of the storage cylinder 39 can be freely extended. Further, the prime mover 36 is operated to rotate the upper surface car wash brush 5. Then, the prime movers 3 and 3 are operated, and the traveling frames 1 start going forward by the rotation of the wheels 8 and 8. Therefore, as shown in FIG. 7, the upper surface car wash brush 5 is lowered to the position (5b).
At this time, the traveling position detecting means D ₁ outputs a signal relating to the position of the traveling frame 1, and the upper car wash brush position detecting means D ₆ outputs a signal relating to the position of the upper car wash brush 5. Then, the traveling frame 1 moves forward to the position (1a)
When the start position detecting means D ₁₁ is left, the cam 33 does not operate the limit switch 32 and the start position detecting means D ₁₁ does not output a signal. Therefore, operation proceeds from step S ₄ to step S _5. At this time, as shown in FIG.
Touches the vehicle body of the automobile V at positions (5c, 5d, 5e) and performs brushing processing. On the other hand, in step S ₅ , the traveling position detecting means D ₁ and the upper surface car wash brush position detecting means
Output signal is input D _6, in step S _6, the vertical position setting means D ₁₂ sets the vertical position of the upper surface drying nozzle 2, at step S _7, the storage means M, to correspond to the traveling position storage Let These steps S ₅ to S _7, outbound signals reciprocating row signal generating means D ₈ are repeated until no output in step S _8. Then, as shown in FIG. 7, the upper surface car wash brush 5 advances to the position (5f to 5g), and the traveling frame 1 moves to the position (1f).
Upon reaching b), it said forward stroke signal is not output, the operation proceeds to step S ₉ from step S ₈ of FIG. 8. In step S ₉ , the prime movers 3 and 3 are deactivated and the traveling frame 1 is stopped. Further, the prime mover 36 is deactivated, the rotation of the top car wash brush 5 is stopped, and the storage cylinder 39 is driven by the control device 65 to raise the top car wash brush 5. At that time, when the magnet 37 moves up to the position (5h) shown in FIG. 7, the magnet 37 operates the reed switch 38.
The upper surface car wash brush upper limit position detecting means D ₇ outputs a signal.
Therefore, the control device 65 stops the storage cylinder 39,
The upper surface car wash brush 5 is stored in the upper limit position, and the brushing process is ended.

Next, FIG. 9 shows a setting principle of the vertical position of the upper surface drying nozzle 2 at step S ₈ described above. The upper surface car wash brush 5 descends from its upper limit position (5a) to a position where the pivot 34 rotates by an angle θ ₁ and contacts the upper surface of the vehicle body of the automobile V. At this time, the swing arm 35 is inclined by an angle theta ₂ with respect to the horizontal line H that passes through the pivot 34. This angle θ ₂ can be easily obtained from the angle θ ₀ at the upper limit position (5a) and the output signal of the above-mentioned top car wash brush position detection means D ₆ corresponding to the angle θ ₁ . Then, when the distance between the centers of the pivot shafts 34 and the support shaft 2 ₁ is L, the distance A from the horizontal line H to the center of the support shaft 2 ₁ is expressed by Equation (1).

A = Lsin θ ₂ (1) Since the optimum position for the drying process of the upper surface drying nozzle 2 is the ascending / descending position shown in the figure, the ascending / descending position setting means
The ascending / descending position SD ₃ from the upper limit position set by D ₁₂ is expressed by equation (2).

SD ₃ = A + X + C (θ ₁ ) = Lsin θ ₂ + X + C (θ ₁ ).
(2) X is a numerical value determined by the upper limit position of the upper surface drying nozzle 2 and the height position of the pivot 34. Further, the correction value C (θ ₁ ) is changed by the angle θ ₂ of the swing arm 35 from the horizontal line H, because the pressure of the upper surface car wash brush 5 against the upper surface of the vehicle body of the automobile V is changed and the upper surface car wash brush 5 is deformed. intended to compensate for changes in the distance between the vehicle body upper surface and the center of the vehicle V of the support shaft 2 ₁ a numerical value defined for the pre-theta _1. At this time, the output signal of the travel position detector D ₁ is the one corresponding to the position SD _1. However, the top surface drying nozzle 2 is at position SD ' ₁ . Then, with respect to the direction in which the traveling frame 1 is the forward stroke, since those positions SD ₁ is increased, the position SD ₁ 'is represented by equation (3).

SD ₁ ′ = SD ₁ −B = SD ₁ −Lcos θ ₂ (3) The elevation position SD ₃ and the distance B are stored in the control means 60 in advance so as to correspond to the angle θ ₁ .

Therefore, in the storage means M, data represented by the formula (2) is stored at an address represented by the formula (3).

FIG. 10 is a diagram showing a drying process when the traveling frame 1 goes backward, and FIG. 11 is a flowchart showing the operation of the control means 60 in that case.

In FIG. 10, when the traveling frame 1 is at the position (1b) and the upper surface drying nozzle 2 is at the upper limit position (2a), when the reciprocating signal generating means D ₈ outputs a signal indicating the backward movement, the control is performed. The means 60 operates based on the flowchart of FIG. Drying whether determined in step S _11. Then, if the drying process proceeds to step S _13, performs other processing proceeds to step S ₁₂ otherwise. In step S _13, it initializes the variable I "0", the inclination angle of the vehicle body upper surface to the variable J is set to a value corresponding to the number of drying processes performed on windshield or rear glass is above a predetermined value. Then, the blowers 9 and 9 are operated, and
By operating the prime movers 3 and 3, air is ejected from the upper surface drying nozzle 2 and the traveling frame 1 returns to start the drying process. At this time, when the upper surface drying nozzle 2 swings due to an operation failure of the control means 60 or the like, for example, the upper surface drying nozzle 2 comes into contact with the upper surface of the vehicle body of the automobile V, the swing limit switch 20 operates. Therefore, in step S _14, it is determined that the output signal of the swing limit switch 20 is present, and in step S ₁₅
And all operations are stopped. On the other hand, if the inconvenience of malfunction or the like, the process proceeds to step S _16, and inputs an output signal of the traveling position detecting means D _1. Then, I read the stored content of the storage means M in step S _17. At this time, the first
As shown in FIG. 0, the upper surface drying nozzle 2 includes the swing arm 35.
The distance D is away from the center of the axis 34. Therefore, read address Ad when the traveling position SD ₁ is expressed by equation (4).

Ad = SD ₁ + D (4) The set value SD stored at the address Ad in the equation (4).
_The upper and lower position ₃ is optimum for the drying process of the upper surface drying nozzle 2. At this time, the set value SD _3X stored at the address Adx, which is distant from the address Ad by a predetermined value on the side corresponding to the forward direction of the traveling frame 1, is also read. Then, the set value SD _3X from the set value SD ₃ is subtracted in step S _18, the absolute value of the value is judged whether or not a predetermined value or more. If the absolute value of the value is more than the predetermined value, since the inclination angle of the vehicle body upper surface of the vehicle V is the case is not less than the predetermined value, the process proceeds to step S _19, otherwise proceeds to step S _21. Step S
_{At 19} , it is judged if the variable I is equal to "0". I =
If it is 0, the output signal of the traveling position detecting means D ₁ at that time is the position where the inclination angle of the upper surface of the vehicle body of the automobile V exceeds the predetermined value, so that value is stored. In addition, the variable I is set to "1"
increase. Therefore, this variable I is the number of times that the windshield and the rear glass in which the inclination angle of the vehicle body upper surface of the automobile V is a predetermined value or more have been dried. Step S ₂₁
Then, the value of the variable I is determined. When I = 0, it means that the inclination angle of the vehicle body upper surface of the automobile V has not reached the predetermined value or more, and therefore, the process proceeds to step S ₂₅ . When 0 <I <J, it means that the drying process of the windshield and the rear glass in which the inclination angle of the upper surface of the vehicle body of the automobile V is equal to or more than the predetermined value has ended, but the number of times set in the variable J has not been reached. , The lifting control means D ₅ raises the upper surface drying nozzle 2, and the prime mover control means D ₄ steps the traveling frame 1.
Returned to the travel position corresponding to the output signal of the travel position detector D ₁ stored in S _20. Then, since the drying process again, "1" increases the variable I in step S _23. Then, the process proceeds to step S _25. When the I = J, back to the initial value "0" to the variable I in step S ₂₄ since it is the case of performing only the drying process set number of, the process proceeds to step S _25. In step S ₂₅ , the upper surface drying nozzle lifting position detecting means D ₉
The output signal SD _{4 of} is input. Then, in step S _26,
It is compared with the set value SD ₃ . As a result of this comparison, SD ₄ ＞ SD
_{If 3} then step S ₂₇ , if SD ₄ = SD ₃ then step S _27
29 , and if SD ₄ <SD ₃ , proceed to step S ₂₈ . In step S _27, the solenoid valve 53 becomes deenergized cut the current flowing through the solenoid coil L53. Therefore, since the hydraulic oil is supplied to the cylinder 4, the upper surface drying nozzle 2 moves up. Then, the loop of steps S ₂₅ , S ₂₆ , S ₂₇ is repeated until the upper surface drying nozzle 2 reaches the optimum position. In step S _28, the solenoid valve 53 is energized current flows in the solenoid coil L53, by the weight of the top drying nozzle 2, the hydraulic oil supplied to the cylinder 4,
Since it returns to the pressure vessel 54, the upper surface drying nozzle 2 descends.
At this time, since the check valve of the check valve 55 with the fixed throttle is closed, the hydraulic oil is adjusted by the fixed throttle. Therefore, the upper surface drying nozzle 2 descends at a lower speed than when it rises. Then, the loop of steps S ₂₅ , S ₂₆ , S ₂₈ is repeated until the upper surface drying nozzle reaches the optimum position. In step S _29, the solenoid valve 51, since the current flowing through the solenoid coil L51, is energized. Therefore, the stopping device 6 is actuated and the piston rod 29 is stopped, so that the upper surface drying nozzle 2 is kept in a constant lifting position. Then, when the traveling frame 1 returns to the position (1a) shown in FIG. 10 and the start position detecting means D ₁₁ outputs a signal, the determination in step S ₃₀ proceeds to step S ₃₁ , and if no signal is output, step S ₃₁ Return to ₁₆ . Therefore, the upper surface drying nozzle 2 is
As shown in FIG. 10, it moves up and down with respect to the positions (2b to 2i) to maintain the upper surface of the vehicle body V and a position suitable for the drying process. Also, in the rear glass part it goes up and down with the position (2c, 2d, 2e, 2c, 2d), and in the windshield part it goes up and down with the position (2g, 2i, 2h, 2g, 2i),
The drying process is performed multiple times. At this time, if it is performed twice, the variable J may be set to "2". When the process proceeds to step S _31, the blower 9, 9 and a motor 3,3 is stopped to raise the upper surface drying nozzle 2. At this time,
As shown in FIG. 10, when the upper surface drying nozzle 2 reaches the position (2j), the upper surface drying nozzle upper limit position detecting means D ₁₀ outputs a signal to stop the ascent and finish the drying process.

Next, the effect peculiar to the above-described embodiment of the present invention will be described.
According to the embodiment of the present invention described above, the swing limit switch
When 20 is activated and outputs a signal, all operations are stopped.
In addition, a flexible guide roller is provided in the lower center of the upper surface drying nozzle 2.
11 and 11 are provided. Therefore, even if the control device 60 malfunctions or the like and the upper surface drying nozzle 2 comes into contact with the vehicle body of the automobile V, the vehicle body is less likely to be damaged.

Further, the stop device 6 provided in the cylinder 4 stops the piston rod 29. Therefore, the upper surface drying nozzle 2
Is fixed in the up and down position when the piston rod 29 is stopped. Therefore, the gap between the upper surface drying nozzle 2 and the upper surface of the vehicle body of the automobile V can be accurately maintained at a constant interval suitable for the drying process.

Although the embodiments of the present invention have been described above in detail, the present invention is not limited to the above embodiments, and various design changes can be made without departing from the present invention described in the claims. It is possible.

For example, as the vehicle body detection means, the traveling frame 1
It is possible to use a plurality of sensors provided in the vertical direction on the side facing the automobile and an ultrasonic transceiver. In these cases, the up-and-down operation of the upper surface drying nozzle 2 and the traveling direction of the traveling frame 1 can be controlled while detecting the vehicle height, so that only the drying process can be performed for the reciprocating movement of the traveling frame 1.

Further, the prime mover can be used in place of raising and lowering the upper surface drying nozzle 2 using the cylinder 4, and can be supported by a swing arm instead of being hung by the chains 21 and 21.

Further, in such a case that decided vehicle orientation relative to the traveling frame 1, the absolute value of a value obtained by subtracting the set value SD _3X from the setting value SD ₃ performed at step S ₁₈ it is determined whether a predetermined value or more , the process proceeds to step S ₁₉ if the predetermined value or more, instead proceeds to step S ₂₀ is equal to or less than a predetermined value,
The process proceeds to step S ₁₉ when the sign of the subtracted value is a code which has been predetermined by car orientation step when not code previously determined by whether the absolute value is equal to or larger than a predetermined value S ₁₉ or Step S
_You may go to ₂₀ . In this case, it is possible to perform only one of the drying processes of the windshield or the rear glass in which the inclination angle of the upper surface of the vehicle body of the automobile is a predetermined value or more, a plurality of times. Therefore, the time required for the drying process can be further shortened by performing the drying process on the windshield, which requires particularly careful treatment, a plurality of times.

Furthermore, instead of pivotally supporting the upper surface car wash brush 5 using the swing arm 34, as shown in FIG. 12, a chain 68 is suspended around a sprocket 66 and a sprocket 67 driven by a prime mover 71, and the chain 68 is suspended. A bogie 69 and a balance weight 70 are provided at symmetrical positions with respect to 68, and the bogie 69 has a support shaft for the upper surface car wash brush 5.
2 ₁ may be pivotally supported.

C. Effects of the Invention As described above, according to the vehicle body drying apparatus of the present invention, since the traveling direction of the traveling frame and the elevation of the upper surface drying nozzle are controlled according to the inclination angle of the upper surface of the vehicle body,
After performing a drying process on the portion where the inclination angle is equal to or larger than a predetermined value, the upper surface drying nozzle is raised, the traveling frame is returned to a traveling position where the inclination angle exceeds a prescribed value, and the traveling frame is again traveled. Along with this, by vertically moving the upper surface drying nozzle, the drying process is performed again for the portion where the inclination angle of the upper surface of the automobile body is equal to or greater than the predetermined value.

Therefore, only the windshield or the rear glass having the inclination angle of a predetermined value or more can be dried a plurality of times.

Therefore, the front glass and the rear glass can be carefully dried, and the drying process does not require a long time.
