Next, the operation of the embodiment of the present invention will be described mainly with reference to FIGS.

FIG. 4 is a polishing process diagram of the upper surface of the vehicle body when the traveling frame 1 is going forward, and FIG.
FIG. 8 is a polishing process diagram of the upper surface of the vehicle body at the time of returning.

[0025] The running frame 1 is stopped at a start position (FIG. 4, left end position). This position is detected when the start position detection switch 43 is operated by the cam 44. If you press the start switch 48 here,
Due to the rotation of the motor 20, the top buff 17 at the upper limit position (a) is rotated forward (rotation in the counterclockwise direction in FIG. 4), and the elevating torque motors 23 are driven to rotate forward with the first voltage. The top buff 17 descends from the upper limit position (a). When the top buff 17 descends to the lower limit position (b), the lower limit detection switch
Torque motor 23 by the operation of the switch 32 is deactivated, by carriage C _1, C ₂ is abutting the lower limit stopper 54, the Toppubafu 17 stops descending, forward rotation of the driving motor As a result, the traveling frame 1 starts going forward.

[0026] As the traveling frame 1 moves forward, the top buff 17 at the lower limit position reaches the position (c) and reaches above the front end of the hood surface of the vehicle V.

At this time, when the height of the hood of the vehicle V is relatively low as shown in FIG. 4C, the guide frame 6 is held at the substantially vertical neutral position while the top buff 17 The lower surface contacts the front end of the hood of the vehicle V, and a repulsive force at that time causes a predetermined or more lifting force to act on the top buff 17.
7 rises along the guide rails 8,8. Next, if the lifting force acting on the top buff 17 decreases to a predetermined value or less due to the elevation of the top buff 17, the elevation of the top buff 17 stops. In this manner, the top buff 17 moves along the hood surface of the vehicle V, and the hood surface can be buffed or polished by the top buff 17.

As shown in FIG. 4C, in the case of the vehicle V 'having a relatively high bonnet surface, when the top buff 17 comes into contact with the front end of the hood, the contact reaction force causes the rearward reaction. pushed, thereby guiding frame 6 is swung backwards R (Fig. 4 left) axially supported P portion around a substantially vertical neutral position N against the spring force of the neutral spring 35 _1, 35 _2. As a result, the small-angle switch 39 is actuated, and the lift torque motors 23, 23 are reversely driven with the second voltage by the control signal from the control means 47 which receives the detection signal therefrom, and the top buff 17 is forcibly raised. Is done. Thereafter, the swinging power acting on the guide frame 6 to the rear R is released by this ascent, and when the small angle switch 39 becomes inactive, the lifting torque motors 23 and 23 become inoperative and the top buff 17 is held by the repulsive force. It rises with power. At this time, the guide frames 6 are neutral springs 35 ₁ , 35 ₂
With the resilience of this, the small angle switch 39 is quickly deactivated from the swinging position of the rear R to the substantially vertical neutral position N before the top buff 17 separates from the vehicle body surface.
7 can polish the hood surface of the vehicle V without leaving the hood surface.

[0029] If the top buff 17 comes to the position (d), which is the boundary between the hood and the front glass surface, from the position (c) due to the continuation of the traveling of the traveling frame 1, the top buff 17 comes into contact with the inclined surface of the windshield and becomes neutral. swings to the left against the spring 35 _1, 35 ₂ of the elastic force, to actuate the small angle switch 39. As a result, the elevating motors 23, 23 are re-rotated with the second voltage via the control means 47, and the top buff 17 is raised along the guide rails 8, 8. The guide frame 6 has neutral springs 35 ₁ , 35
_When it is returned to the neutral side by ₂ and the small-angle switch 39 is deactivated, the elevating motor is also deactivated and the elevation of the top buff 17 is stopped. Then, the top buff 17 is raised by receiving a repulsive force due to contact with the windshield of the vehicle body. As described above, the top buff 17 rises along the front glass surface while polishing the front glass surface by repeating the operation and non-operation of the lifting torque motors 23 based on the forward and backward swing of the guide frame 6.

[0030] The subsequent forward stroke continues by running frame 1, Toppubafu 17 (e) when moving the roof surface from the front glass surface comes to the position, the guide frame 6 swings to the left (rear R) Small angle switch 39 There returns to substantially vertical neutral position by the elastic force of the neutral spring 35 _1, 35 ₂ from the state of being operated, Toppubafu 17 small angle switch 39 becomes inoperative before leaving from the vehicle body surface, the torque motor 23,
Since the 23 is deactivated, the top buff 17 can move without separating from the windshield surface of the vehicle body along the roof surface to polish those surfaces.

In this process, depending on the shape of the vehicle body, the guide frame 6 swings largely to the left, and the large-angle switch 40 may be operated.
When the traveling of the traveling frame 1 is temporarily stopped by stopping the operation of the traveling motor 2 and the large-angle switch 40 is deactivated,
The traveling of the traveling frame 1 is restarted.

[0032] As the traveling frame 1 continues to travel, the top buff 17 reaches the position (f) on the roof surface of the vehicle body,
Polices the roof surface, that the traveling frame 1 has reached a predetermined distance L ₁ which is previously set from the start position, the traveling position detecting means 42 detects, thereby elevating motor 23 is in the third voltage The top buff 17 is driven forward, and the top buff 17 descends.
The top buff 17 contacts the roof surface with an appropriate pressing force by balancing the repulsive force received from the roof surface, and the roof surface can be efficiently polished.

[0033] When the top buff 17 polishes the roof surface and reaches the rear end position (g), the repulsive force received from the vehicle body surface decreases and the top buff 17 descends along the rear glass surface. At that time, the lifting torque motor 2
Since 3, 23 continue the forward rotation drive from the position (f) of the previous step, the top buff 17 can polish the rear glass surface without leaving the surface.

[0034] The top buff 17 has finished polishing on the rear glass surface and is at the front position on the trunk surface (h).
When it reaches the position, the top buff 17 is
When the lowering force by the balance 23 and the repulsive force received from the trunk surface are balanced, the lowering of the top buff 17 stops, and the top buff 17 can polish the trunk surface with an appropriate surface pressure.

[0035] The forward stroke continues traveling frame 1, a photoelectric sensor 46 provided on the traveling frame 1 detects the rear end of the vehicle V, the travel position L ₂ to be detected by the traveling position detecting means 42 are stored.

When the top buff 17 passes the rear end of the vehicle V, its lowering is stopped by the lower limit stopper 54. When the traveling frame 1 reaches the forward stop position (the right end position in FIG. 4, the return start position), the traveling frame 1
Stops, the top buff 17 reaches the position (i), and the polishing of the upper surface of the vehicle body by the forward movement of the traveling frame 1 ends.

It should be noted that the top buff 17 corresponds to the above (e)-
In the process of (i), the guide frame 6 is
When the small angle switch 39 is operated by swinging to the left (FIG. 4 left), the lifting torque motors 23, 23 are reversely driven at the second voltage, and the top buff 17 is raised. Then the neutral spring 35 _1, 35 ₂ of the guide by the force frame 6 Ri small angle switch 39 return to the substantially vertical neutral position N becomes inoperative, the torque motor 23 is driven forward by a third voltage . As a result, the top buff 17 is lowered, and the lowering of the top buff 17 is stopped at a position where the lowering force of the torque motors 23 and the repulsive force received by the top buff 17 from the upper surface of the vehicle body are balanced. Is continued.

(1). Next, at the forward end position of the traveling frame 1, that is, the return start position (FIG. 5, right end position), the top and bottom buffs 17 are driven in the reverse direction (FIG. 5, clockwise) by disabling the elevating torque motors 23, 23. Running frame 1
Go home. Thereafter, when the traveling frame 1 goes forward,
The trunk surface and the rear glass surface of the vehicle can be polished by the same operation as (b) to (f). In this case, the guide frame 6 swings forward F (FIG. 5, right side) by contacting the vehicle body surface.

(2). Continued going back of the traveling frame 1,
The top buff 17 reaches the roof surface and the travel position detecting means 4
2 detects that the now running position go-around by a predetermined distance B set in advance from the traveling position L _2, lifting the torque motor 23 is driven to rotate normally at the third voltage. Accordingly, the top buff 17 polishes the roof surface and the bonnet surface by the same operation as in (f) to ( li ) during the forward movement.

When the traveling frame 1 reaches the forward end position, that is, the start position (the left end position in FIG. 5), the reversing of the traveling frame 1 and the rotation of the top buff 17 are stopped, and the torque motors 23, 23 are driven in reverse to drive the top buff. The top buff 17 is stopped at the upper limit position when the carriages C ₁ , C ₂ abut against the upper limit stoppers 53, 53, and the polishing of the traveling frame 1 in the regression is completed.

In the above polishing process, even if the rocking detection means is operated to obtain an appropriate surface pressure from the windshield surface of the vehicle to the roof surface, the rocking shaft fulcrum P to the center of the top buff 17 can be obtained. The short distance between the bonnet and the trunk allows the polishing to be performed with the appropriate surface pressure without shortage of the surface pressure. As a result, the upper surface of the vehicle body such as the bonnet surface, the windshield surface, the roof surface, and the rear glass surface Polishing can be performed efficiently, uniformly and reliably over the entire area. In addition, the bonnet surface of the vehicle tends to be less polished by polishing than the roof surface due to the heat radiation of the engine in the engine room. In order to sufficiently polish the bonnet surface, the top buff 17 Surface pressure,
It is desirable to make the surface pressure higher than the surface pressure on the roof surface. However, as in the above-described embodiment, the lower part of the guide frame 6 supporting the top buff 17 is pivotally supported so as to be pivotable from the windshield surface of the vehicle. The swing detection means is activated at an appropriate surface pressure around the roof surface, and the surface pressure of the bonnet surface can be made higher than that of the roof surface even if the roof surface is at an appropriate surface pressure. The surface and the roof surface can be satisfactorily and uniformly polished.

The lower end of the guide frame 6, which supports the top buff 17 so as to be able to move up and down as in the above embodiment, is pivotally supported by the traveling frame 1 so that the top buff 17 is relatively close to the pivot P point. By contacting the upper surface of the vehicle V with the vehicle body, the swing angle of the guide frame 6 at the time of contact with the vehicle body can be made relatively large, whereby the accuracy of sensing the swing angle of the guide frame 6 can be increased. , Top buff 17
Can be controlled more accurately.

Although one embodiment of the present invention has been described above, the present invention is not limited to the embodiment, and various embodiments are possible within the scope of the present invention. For example, in the above embodiment, the case where the present invention is applied to a mobile car washer has been described.However, it is needless to say that the present invention can be applied to a fixed type car washer. And the guide frame may not be in a substantially vertical position at its neutral position, and a single lifting / lowering torque motor may be used, or a normal three-phase induction motor may be used instead. . Further, the guide frame for supporting the upper surface processing body such as the top buff may not be a gate type, and the guide rail constituting the frame may be one. The biasing member for holding the guide frame at the neutral position may be an elastic member other than a coil spring, such as a spring or rubber. In the case of an apparatus that performs processing with the upper surface processing body only at the time of going forward or only at the time of returning, the guide frame 6 may be capable of swinging upward and downward from the neutral position N to either the front F or the rear R.
