Next, referring mainly to FIGS.
In detail, the cleaning body W includes a rotating body 71 as a pipe member fitted and supported on the rotating support shaft 11 and a hollow cylindrical air provided on an outer periphery of the rotating body 71. A bag 72, left and right outer side surfaces of the air bag 72, and disk-shaped left and right side plates 73, 73 fixed to the left and right sides of the rotating body 71, and the left and right side plates covering the outer periphery of the air bag 72. A cylindrical cover 75 is fixed to the plates 73, 73, and a plurality of cleaning members 74 are attached to the outer periphery of the cylindrical cover 75 in parallel along the axial direction.

The rotator 71 is formed of a pipe member such as a vinyl chloride pipe.
It is made of an elastic material such as natural rubber or synthetic rubber.
₁ is provided, the valve 72 ₁ is the right side plate 73
It protrudes to the outside through a through-hole formed in the hole. Incidentally, the valve 72 _1, of the same structure as the tire valve of a wheel assembly for a vehicle is used. Further, the cylindrical cover 75 is formed in a hollow cylindrical shape by a flexible non-water-absorbing sheet such as a vinyl chloride sheet.
5 ₁ , 75 ₁ are bent inward along the outer surfaces of the left and right side plates 73, 73, and are fixed by a plurality of fixing members 77 such as bolts and nuts with the ring-shaped pressing plates 76, 76 interposed therebetween. , Are fixed to the left and right side plates 73, 73.

Each cleaning member 74 is formed into a ring by a non-woven fabric made of long fibers such as polyester and nylon.
It is sewn 79 on the outer periphery of the cylindrical cover 75. More specifically, as shown in FIG. 4, the short sides of a plurality of (5 to 6) non-woven fabrics forming a rectangle are joined together. Sequentially sewn into a ring shape 78 is bent into a corrugated shape, and folded portions 74A are provided on the inner peripheral side thereof. These folded portions 74A are sewn 79 around the outer periphery of the cylindrical cover 75 and Attach to In this way, by attaching a plurality of cleaning members 74 to the outer periphery of the tubular cover 75 in parallel in the axial direction, the cleaning members 74 rotate when they rotate as shown in FIGS. And in the direction of its rotator (FIG. 3, left-right direction). By the way, the cleaning effect of the upper surface of the vehicle body can be improved by the spreading of the cleaning members 74 in the rotation direction as described later. The cleaning body W is driven to rotate in a direction in which the upper surface folded portion 74B of the folded portion 74A of the cleaning member 74 is tilted, that is, in a direction indicated by an arrow a in FIG. Enters the inside of the cleaning member 74, the wiper W
f, Wr can be prevented from being caught on the upper surface folded portion 74B, and damage and breakage of the wiper can be prevented and the safety can be ensured.

The air bladder 72 applies a force in a direction opposite to the rotation direction of the rotating member 71 to the cleaning member 74 when the rotating member 71 is driven to rotate and the cleaning member 74 contacts the upper surface of the vehicle body. It has elasticity to be deformed by. When the wipers Wf, Wr and the cleaning members 74 contact each other, the air bag 72 is twisted and deformed by the force applied to the cleaning members 74, so that the rotation of the cleaning member 74 is greater than the rotation of the rotating body 71. Because it is late, the wipers Wf, W
r can be reduced, and the safety of the wipers Wf and Wr can be improved.

Further, since the air bag 72 is provided on the rotating body 71, the length of the cleaning members 74 in the radial direction can be reduced, so that the weight increase of the cleaning body W due to the cleaning members 74 containing water is reduced. Can be done. In addition, the air bag 72 prevents direct contact between the rotating body 71 and the upper surface of the vehicle body, so that safety on the upper surface of the vehicle body can be improved.

The air is injected into the air bag 72 after the cylindrical cover 75 is attached to the left and right side plates 73, 73.

The cleaning members 74 made of the nonwoven fabric are used.
Is that whose weight changes according to the water content,
As a result, the weight of the cleaning body W itself also changes, but since the amount of the change can be reduced, the surface pressure on the upper surface of the vehicle body can be reduced without frequently adjusting the surface pressure by moving the balance weight 16 or the like. Can be equalized. Also, by reducing the increase in weight due to water content, the cleaning body W
Can be prevented from being caused by an increase in weight.

The cleaning members 74 may be made of a woven fabric made of the same fibers in place of the nonwoven fabric. In this case as well, the cleaning members 74 are sewn and attached to the outer periphery of the cylindrical cover 75.

Next, the operation of this embodiment will be described with reference to FIGS.

First, the traveling frame 1 is at the start position (the left end position in FIG. 6), and the first solenoid valve 55 is operated (excited) so that the cleaning body W is held at the upper limit position U. Car wash is assumed to be started from a state where V is stopped at a predetermined position between the rails 2 and 2.

When the start switch 34 is pressed while the cleaning body W is at the upper limit position U and the upper limit switch 26 is operated, the vehicle moves to the right end (travel end position) of the traveling rails 2 and 2 in FIG. writing each maximum travel position Lmax greater than the running position when the frame 1 has reached the storage unit M ₁ ~M ₄ memory means M, to drive the water pump 32, further low rotating cleaning body W in the direction of arrow a Then, the washing body W is impregnated with water by spraying water from the washing water spray pipe 31. After the cleaning body W has been hydrated for a predetermined time, the cleaning body W is rotated at a high speed, and the cylinder 51 is deactivated by the deactivation (non-excitation) of the first solenoid valve 55. As a result, when the cleaning body W is lowered to the lower limit position D, the traveling frame 1 is forward-traveled at a high speed while maintaining the cleaning body W at a high speed (step S1).

Next, the traveling position L of the traveling frame 1 is read (step S2). Then, steps S3, S4, S
Steps S2 to S9 are repeated since NO is determined in Steps S6 to S8 and YES is determined in Step S9.

When the traveling frame 1 continues traveling forward and the first photoelectric switch K ₁ comes to the K ₁ A position and detects the windshield f (step S6), X is added to the current position L at this time and travel position obtained by subtracting the _{R 1 L 1 (L 1 =} L
+ X-R ₁ ) and a running position L ₂ (L ₂ = L + X + R ₂ ) obtained by adding X and R ₂ to the current position L, and storing the running position L ₁ in the storage unit M ₁ and the running position L each store ₂ in the storage section M ₂ (step S10).

X is the support shaft 9₁, 9_TwoAnd photoelectric switch

In step S6, when the first non-detection is changed to the detection, the result is YES.

As a result, the current position L becomes L ₁ ≦ L ≦ L ₂
At step S3, the result is YES in step S3, and the cleaning body W is rotated at a low speed (rotation direction, direction of arrow a), and the descending force of the cleaning body W is further reduced by the descending force reducing means G (step S3).
13).

[0042] When the current position L exceeds travel position L _2, cleaning body W high-speed rotation (rotational direction, the direction of the arrow a) is migrated to the cylinder 51 is deactivated (step S
5).

The first photoelectric switch K ₁ time (step S7) comprising the non detection from the detection, the storage unit M ₅ the current position L at that time as the travel distance L _5.

[0044] When the second photoelectric switch K ₂ detects the rear end of the vehicle V becomes undetected from the detection by the K ₂ A position (step S8), and the traveling position L ₅ stored in the storage unit M ₅ at that time traveling position L obtained by adding the X and R ₃ in (first photoelectric switch K ₁ becomes not detected from the detection by the K ₁ B position, the travel position when it detects the rear window r of the car V)
₃ (L ₃ = L (L ₅ ) + X + R ₃ ) and a running position L ₄ (L ₄ = L _{4) obtained} by adding X and R ₄ to the running position L _5.
(L ₅ ) + X + R ₄ ), and stores the travel position L ₃ in the storage unit M ₃ and the travel position L ₄ in the storage unit M ₄ (step S12).

Note that R ₃ is a predetermined horizontal distance between the support shafts 9 ₁ and 9 ₂ and the K ₁ B position at the traveling position L ₃ , and R ₄ is the traveling position L ₄ Is the predetermined horizontal distance between the support shafts 9 ₁ and 9 ₂ and the K ₁ B position.

[0046] Thus is the current position L is YES at step S4 when L ₃ ≦ L ≦ L ₄ washing, cleaning body W is low speed (rotation direction, the direction of the arrow a) is, by further lowering force reducing means G lowering force of the body W is reduced, and the running frame 1 traveling motor 5 _1, 5 ₂ becomes the low speed rotation is in low speed (step S14).

[0047] Then the current position L, and more than traveling position L _4, the cleaning body W is rotated at a high speed (rotation direction, the direction of the arrow a), the cylinder 51 is deactivated (step S5).

When the traveling frame 1 travels forward a predetermined distance after the second photoelectric switch K ₂ detects the rear end of the vehicle V, the cleaning of the upper surface of the vehicle body by the cleaning body W in the forward traveling ends (step S9). .

Thus, during the forward traveling of the traveling frame 1, the washing body W includes a portion of the upper surface of the vehicle body including a portion attached to the front glass f and the rear glass r (in FIG. 6, a predetermined section L corresponding to the front glass f). and ₁ ~L _2, while moving the predetermined interval L ₃ ~L ₄₎ corresponding to the rear window r,
The number of revolutions of the cleaning body W is reduced as compared with the case where the cleaning body W is moved in another section, and the lowering force is further reduced.

The rotation speed of the cleaning body W is reduced, and the rotation body 71 of the cleaning body W approaches the upper surface of the vehicle body as the rotation speed decreases (in FIG. 8, the cleaning body W is moved from high rotation to low rotation). When the rotation is changed to the rotation, the cleaning body W is changed from the high rotation position WH to the low rotation position WL, and the rotation body 71 is lowered from the rotation body position at the high rotation position WH to the rotation body position at the low rotation position WL, and is placed on the upper surface of the vehicle body. Approaching) can be suppressed by reducing the surface pressure exerted by the cleaning body W on the upper surface of the vehicle body as described above, that is, by controlling the rotating body 71 of the cleaning body so as not to approach the upper surface of the vehicle body, It is possible to improve the safety for the wipers Wf and Wr.

As shown in FIG. 9A, the conditions are set so that the cylindrical cover 75 rises from the upper surface of the vehicle body due to the contact between the cleaning member 74 and the upper surface of the vehicle body.
(B) when the condition is set so that the cleaning member 74 is crushed, and when the latter condition is set, the rotational speed of the cleaning body W is reduced; By reducing the surface pressure on the upper surface of the vehicle body, the cleaning body W
Can reduce the force of pressing the upper surface of the vehicle body, so that the safety for the wipers Wf and Wr can be improved.

Generally, it is difficult to clean the rear wiper Wr more safely than the front wiper Wf. Therefore, when cleaning the vehicle V equipped with the rear wiper Wr, a switch (not shown) is operated. or cleaning body W is in inoperative the cleaning body W in the running position L ₃ reaching the beginning of the rear window r, or or covered with a protection to the rear wiper Wr, by fixing the rear wiper Wr with packing tape or the like, rear wiper Wr The part may be cleaned by the cleaning body W. However, when the rear wiper Wr is overlooked and the switch operation, the use of the protective device, or the fixing with the adhesive tape or the like is forgotten, the step S1 is performed.
By the operation of 4, the safety for the rear wiper Wr can be improved as much as possible.

The cylindrical cover 75 is made of an elastic material, and when the rotating body 71 is driven to rotate and the cleaning member 74 is brought into contact with the upper surface of the vehicle body, the rotating direction of the rotating body 71 applied to the cleaning member 74 The cylindrical cover 75 may have elasticity to be deformed by a force in the opposite direction. Thereby, the cylindrical cover 75 is torsionally deformed by the force applied to the cleaning member 74 due to the contact between the front wiper Wf or the rear wiper Wr and the cleaning member 74, and the rotation of the cleaning member 74 is more than the rotation of the rotating body 71. Therefore, the force applied to the front wiper Wf or the rear wiper Wr can be reduced, and the safety for the wiper Wf or Wr can be improved.
