In FIG. 1, a running frame F formed in a gate shape so as to be able to straddle a vehicle is supported so as to be able to reciprocate via running wheels W on an inner rail R laid on the ground.

A pair of vehicle body side drying devices are provided on both left and right sides 1 of the traveling frame F for drying the vehicle body side surfaces of the wet vehicle (1) after being washed. Since both of the pair of drying devices have the same structure, one of them will be explained in detail below.

A blower 2 is fixedly installed on the side 1 of the traveling frame F.
One end of a stretchable and flexible air guide pipe 3 is connected to a downwardly opening discharge port of the blower 2 .

The air guide pipe 3 is curved toward the inside of the traveling frame F, and has a side nozzle body N having a trapezoidal shape when viewed from the front at the other end.
The inlet of the nozzle body N is connected to the nozzle body N, and the nozzle 4 of the nozzle body N is opened toward the inside of the traveling frame F. The side nozzle body N is tiltably supported by the traveling frame F.

and the neutral arm 16 cooperate to maintain the side nozzle main body N in the neutral position as shown in FIG. 3(A). And Figure 3 (A
), if an external force acts on the side nozzle body N in the direction of arrow (C) or arrow (C), the side nozzle body N4 will oscillate as shown in FIG. 3(B) or FIG. 3(C). However, when the external force is released, the side nozzle body N returns to the neutral position.

Further, a neutral position detection device ND for detecting the neutral position of the side nozzle body N is provided between the side nozzle body N and the tilting arm 6. This device Nゎ is composed of a detection piece 18 fixed to the upper rotating shaft 14 and a proximity switch 19 provided on the tilting arm 6 facing the detection piece 18. and proximity switch 1

It is detected whether the vehicle vA is a passenger car type.

A guide rail 23 extending in the left-right direction is provided on the upper part 22 of the traveling frame F, and a pair of left and right carts 24° 24 supported by the guide rail 23 so as to be freely movable is equipped with a motor 25.

The first side surface position detecting means, the second side surface position detecting means, and the third side surface position detecting means are constituted by these. Further, the traveling frame F is provided with a top brush 29 that can be raised and lowered to clean the top surface of the vehicle, and a pair of left and right rocker brushes 30 and 30 that can be opened and closed to clean the lower side surfaces of the vehicle (eighth).
(See Figures (A) and (B)).

By using the side drying device of the first embodiment, various controls can be performed as necessary. First of all,
The operation corresponding to the invention described in claim 1 will be explained based on the first embodiment with reference to the flowcharts of FIGS. 8(A) and 8(B) and FIG. 9.

In the cleaning process of the vehicle V by running the gate-type traveling frame F, the side brush 26, top brush 29, and rocker brush 30 provided on the traveling frame F clean the vehicle body surface prior to the drying process of the vehicle body surface as usual. Brushing cleaning is performed, and in this brushing cleaning process, the side trash 1 full zero body N is held in a retreated upright position as shown by the solid line in FIG. so that the side nozzle main body N does not get in the way of brushing cleaning. It goes without saying that even when the traveling frame F is in the standby position, the side nozzle body N is held in the retracted upright position.

Now, in the flowchart of FIG. 9, step S1
The traveling frame F starts to move forward, and in step S2, the vehicle height detection means consisting of the light emitter 20 and the light receiver 21 detects whether the vehicle height is larger than a predetermined value, that is, whether the vehicle is a pan-type vehicle Vm. If YES, the result is stored in step S3. Next step S4
It is determined whether the forward movement has ended or not, and if the forward movement has not ended, the process returns to step S2. If the forward movement is completed in step S4, the cleaning is completed in step 18 by stopping the rotation of each brush 26, 29, and 30 and moving it to the storage position, and then in step S5 the vehicle height is memorized. It is determined whether If the vehicle height is memorized,
That is, when the vehicle is a pan-type vehicle V3, in step S6, the side nozzle main body N is held in the retreated position shown by the solid line in FIG. The nozzle 4 is held in a substantially upright position and placed along the side surface of the vehicle VB. In the following step S7, the blower 2 is driven to blow out pressurized air from the nozzle 4 and the traveling frame F is moved back to dry the side surface of the vehicle body. On the other hand, if the vehicle height is not stored in step S5, that is, if the vehicle is a passenger car type vehicle V^, then in step S8 the side nozzle main body N is moved to the position indicated by the two-dot chain line in FIG. The side nozzle body N is moved to the extended position as shown in , so that the nozzle 4 of the side nozzle main body N is substantially along the inclined side surface of the vehicle body, and in step S7, the side surface of the vehicle body is dried while the traveling frame F is made to go back.

In this way, by appropriately controlling the tilting of the pair of left and right side nozzle bodies N according to the shape of the side surface of the vehicle body, the nozzle 4 can be aligned with the side surface of the vehicle body, thereby efficiently drying the side surface of the vehicle body. It is possible to do so. Note that the upper surface of the vehicle is dried by pressurized air from a conventionally known top nozzle (not shown) provided on the traveling frame.

Note that steps S01 to 304 in the above flowchart indicate additionally selectable steps, and in step 301, the running frame F moves a distance L (from when the side brush 26 opens at the front of the vehicle until it follows the side of the vehicle body). It is determined whether the moving distance of the traveling frame F (see Fig. 8 (B)) has been moved, and if YES, in step 302, the second side position detection means consisting of the second limit switch 2□ Side position detection is performed. That is, when the width of the vehicle is large or when the vehicle is stopped shifted left and right, the trolley 2 that supports the side brushes 26
4 moves outward significantly and the second limit switch 281
1 is activated, the result is stored in step SO3. If the second side position is stored in step SO4, even if the vehicle height is not stored in step S5, that is, even if the vehicle is a low-height passenger car type vehicle vA. , in step S6, the side nozzle body N is held in a vertical position. Thereby, interference between the side nozzle main body N and the vehicle body can be more reliably prevented.

Next, the operation corresponding to the invention set forth in claim 2 will be explained based on the first embodiment with reference to the flowchart of FIG. 10.

In the flowchart of FIG. 10, the forward movement of the traveling frame F is started in step 21-S9, and the forward movement of the traveling frame F is started in step 31-S9.
0, the vehicle height detection means detects whether the vehicle height is larger than a predetermined value, and if YES, the result is stored in step 311. If NO in step S10, it is determined in step 312 whether the traveling frame F has moved a distance, and if YES, in step 313, the first side position detection means consisting of the first limit switch 281 detects the side position of the vehicle. Detection is performed. That is, when the width of the vehicle is large or when the vehicle is stopped with left and right deviations, the first limit switch 28. is activated, step S1
4, the result is stored. Next, in step 315, it is determined whether the forward movement has ended, and if the outgoing movement has not ended, the process returns to step 310. If the outbound trip has ended in step S15, the inbound trip is started, and in step S16 it is determined whether the vehicle height is stored, and if YES, step S
22 At 17, it is further determined whether the side position is stored, and Y
If it is ES, the side nozzle body N is held in the retracted position in step 31B. On the other hand, if the vehicle height is not stored in step S16, or if the side position is not stored in step 317, the side nozzle body N is driven to come out to the tilted position in step S20.

In other words, the side nozzle body N is held in the outwardly retracted position only when the vehicle height is greater than a predetermined value and the side position of the vehicle protrudes outward beyond the predetermined position. When the vehicle size is V, or when the vehicle width is small even if it is a pan-type vehicle (8), the side nozzle main body N is controlled to be tilted inward. After the side nozzle main body N is controlled to the optimum position according to the vehicle in this way, the side surface of the vehicle body is dried in the subsequent step S19.

Note that steps 305 to SO7 in the above flowchart indicate additionally selectable steps, and when the second side position is detected in step 305,
That is, when the second limit switches 28□, 28□ are activated due to positional deviation of the vehicle, the second side position is stored in step SO6. Then, in step S16, NO1, that is, the vehicle is a passenger car type vehicle with a low vehicle height.
, even if the second side surface position is stored in step 307, the side nozzle main body N is held in the vertical position and interference with the vehicle body is prevented.

Next, the operation corresponding to the invention recited in claim 5 will be explained based on the first embodiment with reference to the flowchart of FIG. 13.

In the flowchart of FIG. 13, the forward movement of the traveling frame F is started in step S44, followed by step S45.
It is determined whether the traveling frame F has moved the above-mentioned distance or not, and if YES, the first limit switch 28. The side position of the vehicle is detected by the first side position detection means. In this step S46, the limit switch 28. If activated, step S
The results are stored at step 47. In the following step 848, it is determined whether the outbound movement has ended, and if the outbound movement has ended, the inbound movement is started. In step S49, it is determined whether the side position is stored. If YES, step S
At 50, the side nozzle main body N is held in the retracted position.

On the other hand, if the side nozzle body N is not memorized in step S49, the side nozzle main body N is driven to come out to the tilted position in step S51, and in the subsequent step 352, the side surface of the vehicle is dried.

Thereby, when the side position of the vehicle is on the outside, the side nozzle main body N is held in the vertical position, and when the side position of the vehicle is on the inside, the side nozzle main body N is driven to the tilted position.
