Abstract

PROBLEM TO BE SOLVED: To improve the precision of controlling a washing body in the safe state to an equipment installed on a rear glass surface by controlling the washing body on the basis of the output of a rear wheel detecting means for detecting the rear wheel of a vehicle. SOLUTION: When a present position L passes a prescribed position R10 where a photoelectric switch K3 (rear wheel detecting means) passes a front wheel TF, the photoelectric switch K3 is operated for detection. When the photoelectric switch K3 reaches K3 A position and detects a rear wheel TR, a traveling position L3 in which X and R3 are added to the present position L at that time is stored in a memory means. When the present position L reaches L3 (at that time, a washing body W is situated in the position just before a rear glass surface (r)), the washing body W is changed from high-speed rotation to low-speed rotation, and the contact surface pressure of the washing body W to the car body upper surface is reduced. Thus, the quantity of the rotating center of the washing body W approaching to the car body upper surface can be reduced, and the force added to an equipment installed on the rear glass surface (r) can be also reduced.

A start switch 34 for starting car washing is provided on the surface of a control panel 33 provided on the front of the traveling frame 1. Also, inside the control panel 33,
A control device 35 for controlling the vehicle body upper surface cleaning device, an inverter 36 connected to the torque motor 20, and an inverter 63 connected to the rotary motor 12 are provided.

The inverter 63 is specified by a control signal output from the control circuit C of the control device 35, such as a frequency changing means for changing the output frequency, a voltage changing means for changing the output voltage, and even if the input voltage fluctuates. And a constant voltage means for outputting the applied voltage, and changing the output frequency (that is, the frequency of the voltage applied to the rotary motor 12) to make the rotation speed of the cleaning body W variable. Therefore, the inverter 63 and the rotation motor 12 cooperate with each other to constitute a rotation driving means Dw which rotates the cleaning body W and has a variable rotation speed.

As shown in FIG. 3, the control device 35 includes a traveling position detecting means Ds and a vertical position detecting means D, which will be described below.
e, rear glass position detecting means D _R , lower limit detecting means Dd,
It has the functions of the storage means M, and furthermore, those functions D
The output signals from s, De, D _R , Dd, and M are arithmetically processed based on the control program to operate the traveling motors 5 ₁ and 5 ₂ , the rotating motor 12 of the washing body W, the torque motor 20, and the water pump 32. It has a control circuit C as control means.

The ascending / descending position detecting means De detects the output pulse from the rotary encoder 27 while the washing body W is descending from the time when the washing body W starts descending from the upper limit position U and the upper limit switch 26 becomes inactive. Is added, and while the cleaning body W is rising, the output pulse from the rotary encoder 27 is subtracted to detect the elevation position θ of the cleaning body W as an angle from the upper limit position U. .

The rear window position detecting means D _R is the vertical position detecting means detects the vertical position θ of De is on the cleaning body W, the lower limit position U, the predetermined set position set between D Z (see FIG. 4)
Changes to a small state from a large state than the first set vertical position theta ₁ which is determined in advance corresponding to, when changing to a larger state from the second smallest state, it is determined that the rear window surface r.

The lower limit detecting means Dd is provided with
It is determined whether the elevating position θ detected by e is larger than the second predetermined elevating position θ ₂ in the vicinity of the lower limit position D of the cleaning body W. That is, it is detected that the cleaning body W is at the lower limit position D.

The traveling position detecting means Ds includes the traveling frame 1
When the traveling frame 1 is traveling forward, the output pulse from the traveling position detecting rotary encoder 30 is added based on the time when the start position detection switch 29 becomes inactive after starting traveling forward from the start position. Also, while the traveling frame 1 is traveling backward, the traveling position L of the traveling frame 1 from the start position can be detected by subtracting the output pulse from the rotary encoder 30. Therefore, the traveling position detecting means Ds determines the relative movement position (the traveling position L of the traveling frame 1 with respect to the stopped vehicle V in the illustrated example) between the traveling frame 1 as a frame and the vehicle V as a vehicle in the vehicle longitudinal direction. It can function as relative movement position detecting means for detecting.

The inverter 36 is designated by a control signal output from the control circuit C of the control device 35, such as a frequency changing means for changing the output frequency, a voltage changing means for changing the output voltage, and even if the input voltage fluctuates. And a constant voltage means for outputting the output voltage. In this embodiment, the output frequency of the inverter 36 is constant.

As described above, the weight of the balance weight 16 and the reduction ratio of the torque motor 20 are such that when the torque motor 20 is inactive (non-energized), the cleaning body W is lowered by its own weight, and the cleaning body W The washing body W and the vehicle V make a relative movement while the body and the upper surface of the body contact each other, so that the washing body W can move up and down.

Next, the operation of this embodiment will be described with reference to FIG. First, when the traveling frame 1 is at the start position (the left end position in FIG. 4) and the torque motor 20 has a voltage Vu large enough to raise the cleaning body W to the upper limit position U even when the weight of the cleaning body W is maximum. It is assumed that the washing is started from a state where the voltage is applied and the vehicle V is stopped at a predetermined position (solid line position in FIG. 4).

When the start switch 34 is pressed while the washing body W is at the upper limit position U and the upper limit switch 26 is operated, the water pump 32 is driven to inject the washing water. Further, the cleaning body rotating motor 12 is rotated at a low speed to rotate the cleaning body W at a low speed in the direction of arrow a shown in FIG. Thereby, the cleaning body W is made to contain water. After performing the water-containing step for a predetermined time, the cleaning body rotating motor 12 is rotated at a high speed to rotate the cleaning body W at a high speed in the direction of the arrow a shown in FIG. 4, and the electric power applied to the torque motor 20 is deactivated. The cleaning body W is lowered by its own weight.

When the lower limit detecting means Dd detects that the cleaning body W has reached the lower limit, the traveling frame 1 is caused to travel forward. Since the torque motor 20 is not operated during the forward traveling, the cleaning body W descends by its own weight and comes into contact with the upper surface of the vehicle body with an appropriate surface pressure. As the traveling frame 1 and the vehicle V move relative to each other in the front-rear direction, the cleaning body W moves up and down by contact with the upper surface of the vehicle body, and moves along the shape of the upper surface of the vehicle body.

When the traveling frame 1 travels forward, the photoelectric switch

Then, X is added to the current position L at this time, and R is added.₁Reduced

Line position L_TwoSupport shaft 9 when₁, 9_TwoAnd K₁A position
Is a predetermined horizontal distance between the two.

Then, when the current position L becomes L ₁ (at this time, the cleaning body W is located immediately before the front glass surface f), the cleaning body rotation motor 12 is rotated from high speed to low speed, and the cleaning body W is rotated. While the rotation speed is changed from the high-speed rotation to the low-speed rotation, a predetermined voltage Vs in the direction of raising the cleaning body W is applied to the torque motor 20 to reduce the contact surface pressure of the cleaning body W with respect to the upper surface of the vehicle body. At this time, when the cleaning body W rotates at a low speed, the pipe member 11 ₁ (that is, the center of rotation of the cleaning body W) descends so as to approach the upper surface of the vehicle body, but the voltage Vs is applied to the torque motor 20. it allows the pipe member 11 ₁ can reduce the amount approaching the vehicle body upper surface, yet it is possible to reduce the force applied to the front wiper Wf.

When the current position L becomes L ₂ , the cleaning body rotating motor 12 is changed from low-speed rotation to high-speed rotation, the cleaning body W is changed from low-speed rotation to high-speed rotation, and the torque motor 20 is deactivated. At this time, as the cleaning body W rotates at a high speed, the pipe member 11 ₁ (that is, the rotation center of the cleaning body W) rises away from the upper surface of the vehicle body.
In this way, in the section where the cleaning body W corresponds to the front glass surface f (at least the front wiper Wf), the cleaning body W can be kept in a low-speed rotation state and a reduced surface pressure state.

Further, when the photoelectric switch K ₃ current position L passes the predetermined position R10 passing through the front wheel T _F, thereby detecting operating the photoelectric switch K _3. The photoelectric switch K ₃ is the K ₃ A position detects the rear wheel T _R, stores the running position L ₃ obtained by adding the X and R ₃ in the current position L at this time in the storage means M. Note that R ₃ is a predetermined horizontal distance between the support shafts 9 ₁ and 9 ₂ and the K ₃ A position at the traveling position L ₃ .

Then, when the current position L becomes L ₃ (at this time, the cleaning body W is located immediately before the rear glass surface r),
The cleaning body rotating motor 12 is changed from the high-speed rotation to the low-speed rotation so that the cleaning body W is changed from the high-speed rotation to the low-speed rotation, and the torque motor 20 is supplied with a predetermined voltage Vs in the direction of raising the cleaning body W.
Is applied to reduce the contact surface pressure of the cleaning body W with respect to the upper surface of the vehicle body. As a result, the pipe member 11 ₁ is formed in the same manner as described above.
(I.e., the amount of the rotation center of the cleaning body W approaching the upper surface of the vehicle body can be reduced, and the force applied to the rear wipers Wr ₁ , Wr ₂ as equipment provided on the rear glass surface r) can be reduced. Can be. In FIG. 4, Wr ₁ indicates a rear wiper stopped horizontally, and Wr ₂ indicates a rear wiper stopped vertically.

The cleaning body W becomes Z position, the rear window position detection means D _R detects the rear window surface r, storage means travel position L ₄ obtained by adding the R ₄ to the current position L when the M

₁ , 9 ₂ .

[0038] Then, if the current position L becomes L ₄ (cleaning body W at this time is at a position immediately after the rear glass surface r), low-speed rotation of the cleaning body W to the cleaning body rotation motor 12 from the low speed to high-speed rotation , And the torque motor 20 is deactivated. At this time, as the cleaning body W rotates at a high speed, the pipe member 11 ₁ (that is, the rotation center of the cleaning body W) rises away from the upper surface of the vehicle body.
In this way, in the section where the cleaning body W corresponds to the rear glass surface r (at least the rear wipers Wr ₁ , Wr ₂ ), the cleaning body W can be kept in a low-speed rotation state and a reduced surface pressure state.

When the photoelectric switch K ₂ is moved to the K ₂ A position and the vehicle V travels a predetermined distance after detecting the rear end of the vehicle V, the washing in the forward travel is completed.

The above control of the cleaning body W is carried out by control circuit C, in cooperation with each other and the control circuit C and the photoelectric switch K _3, after detecting the wheel T _R after the vehicle V as the vehicle The wheel detecting means B is constituted. Further, the control circuit C includes:
Relative movement position detection means (running position L) which detects the relative movement position (running position L of frame 1 in the illustrated example) between frame 1 and the vehicle (vehicle V) based on the output of rear wheel detecting means B or the output. Based on the detection position of the detection means Ds), the cleaning body W in a safe manner with respect to the equipment (rear wipers Wr ₁ , Wr ₂ ) mounted on the rear glass surface r.
Is configured as control means for controlling the control.

[0041] In the above embodiments, the third photoelectric switch K ₃ of the rear wheel detection means B, the rear wheel T _R, and detects a tire portion particularly projecting from the vehicle body lower surface downwards, the rear wheel T _R
Can be easily and reliably (clearly) detected. Moreover, the output of the rear wheel detecting means B and the relative motion position detecting means of the frame 1 and the vehicle V (the running position detecting means Ds)
Based on the detected position (travel position L) of the rear wiper Wr ₁ and Wr ₂ on the rear glass surface r (in the illustrated example, the cleaning body W is rotated at a low speed,
The cleaning body W is controlled in such a manner that a predetermined voltage Vs in a direction of raising the cleaning body W is applied to the torque motor 20 to reduce the surface pressure of the cleaning body W). the rear glass surfaces r and longitudinal adjacent site (ceiling surface, the trunk surface) thereof regardless form and height of, rear window position information obtained in connection with the rear wheels T _R, thereon,
Even if there is a displacement between the rear wheel detecting means B (third photoelectric switch K ₃ ) and the cleaning body W in the vehicle front-rear direction, the above-described control of the cleaning body W can be performed. The degree of freedom in the arrangement of the switch K ₃ ) and the cleaning body W is increased. In the illustrated example with Thus, it is particularly effective in a motor vehicle in a position where the rear wheels T _R and the rear window surface r has substantially matches the longitudinal direction of the vehicle body (e.g., notch back type, the hatchback passenger cars).

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various embodiments are possible within the scope of the present invention. In the above-described embodiment, the embodiment in which the frame provided with the washing body is run and the vehicle V is stopped and the washing is performed by performing the washing is described. The present invention can also be applied to a fixed type car washer in which V is moved by a conveyor or the like. In addition, a cleaning motor is applied by a torque motor or the like to lower the cleaning body, and a balance between the lowering force and a force caused by contact between the cleaning body and the upper surface of the vehicle body causes the cleaning body to conform to the body upper surface shape. The present invention can be applied to an apparatus.

Further, in the above-described embodiment, the cleaning body is supported on the frame so as to be able to move up and down via the swing arm. However, in the present invention, the cleaning body is moved up and down along the vertical rail provided on the frame. The present invention can also be applied to an apparatus for cleaning the upper surface of a vehicle body.

Further, at the traveling position L ₃ , the cleaning body W is rotated at a low speed and in the reverse rotation (in the direction opposite to the direction of the arrow a), and at the traveling position L ₄ , the cleaning body W is rotated at a high speed and rotated forward (the arrow a). Direction).
