Then, the hydraulic oil put in the pressurized container 47 is supplied to the cylinder 4 via a check valve 48 with a fixed throttle. The check valve with fixed throttle 48 is opened when the cylinder 4 contracts, and closed when the cylinder 4 extends.

FIG. 5 is a block diagram of a control system when a microcomputer is used as the control means. Control means 50 includes a microprocessing unit 51 performing arithmetic processing, a program and a read Onrii memory M ₁ to the fixed data are stored, a random access memory M used in the storage of the work area and variable data
₂ , an input interface 52, an output interface 53, and a bus 54 connecting them. The input interface 52 includes the running pulse generating means D ₁ , the vehicle detecting means D ₂ , the lifting pulse generating means D ₃ , the reciprocating signal generating means D ₄ , the upper limit detecting means D ₅ , and the start position detecting means D _6. Output signal is input. The output interface 53 is connected to the solenoid coils L ₄₄ and L44 of the solenoid valves 44 and 46 shown in FIG.
Connected to _L46 . The bus 54 is also connected to storage means M comprising a random access memory.

Next, the operation of the embodiment of the present invention having the above-described configuration will be described with reference to FIGS.
In FIG. 6, when the reciprocating line signal generating means D ₄ first outputs a signal indicating the forward direction, the prime movers 27 and 27 operate,
The traveling frame 1 travels rightward in the drawing along the traveling rails 7 from the position 1a to the position 1b.

At this time, the start position detecting means D ₅
Means that, except for the position 1a, the cam 33 is
2 is not activated, so no signal is output. The running pulse generating means D ₁ is provided with the proximity switch 3 when the disk 30 rotates.
1 is operated, so that a running pulse signal is output. Also, the vehicle detecting means D _2, the light of the projector La is blocked by the body of the vehicle, among the plurality of photoelectric switch K ₁ ~K ₁₅ constituting the sensor group systems, photoelectric switch K ₁ provided at the bottom To the photoelectric switch provided at a position corresponding to the upper surface of the vehicle body of the vehicle, so that a signal corresponding to the vehicle height is output. For example, the traveling frame 1 is forward stroke distance L ₁ in FIG. 6, when in the position 1c, the signal of the photoelectric switch K ₁ ~K ₅ is obtained.

At this time, the control means 50 operates based on the flowchart of FIG. When reciprocating row signal generating means D ₄ outputs a signal indicative of the forward stroke, it is determined whether the vehicle height measured in step S _1. Then, the process proceeds to step S _3, if the vehicle height measurement, performs an advance outside of the processing in step S ₂ otherwise. In step S _3, the start position detection means D
The presence or absence of the output signal of ₅ is determined. If Mu output signal goes to step S _4. If the output signal Yes, the traveling frame 1 is the forward stroke, it repeats step S ₃ before proceeding to the right from the position 1a in FIG. Step enter the running pulse signal S _4, one adds to the running pulse count A each time the pulse signal is inputted. In step S _5, and inputs the output signal of the vehicle detection unit D _2. This output signal is a 15-bit signal in which the value of each bit corresponds to the presence or absence of the output signals of the photoelectric switches K _{1 to} K ₁₅ . In step S _6,
Storing the output signal of the vehicle detection means D ₂ as data in address A of the memory means M. In step S _7, the reciprocating line signal generating means D ₄ is determined whether or not a signal indicating the forward stroke. Returns to step S _4, if signal Yes, ends if Mu signal.

Therefore, the storage means M continuously stores data H corresponding to the position of the upper surface of the vehicle body, that is, the vehicle height.

In FIG. 8, the reciprocating line signal generating means D
_{When 4} outputs a signal indicating a go-back, the traveling frame 1 goes back from the position 1b to the position 1a in the left direction in the drawing. Then, the upper surface drying nozzle 2 is moved up and down to perform a drying process.

At this time, the lifting pulse generating means D
₃ outputs a lifting pulse signal because the disk 24 rotates and the proximity switch 25 is operated. When the upper surface drying nozzle 2 starts lowering, the upper limit detecting means D ₆ does not output a signal because the operating member 17 does not operate the upper limit switch 16.

At this time, the control means 50 operates based on the flowchart of FIG. When reciprocating row signal generating means D ₄ outputs a signal indicative of the go-around, it is determined whether a drying process is performed in step S _8. Then, if the drying process proceeds to step S _10, performs the process proceeds out of the process in S ₉ otherwise. The running pulse signal input at step S _10, 1 pulse signal from the running pulse count A at the forward stroke is decremented by 1 for each input to the running number of pulses B. Step S ₁₁
Then, the following calculation is performed on the number of running pulses. 8, the traveling frame 1, and go-around from the position 1b, reaches the position 1d, when the distance from the start position 1a becomes L _2, running pulse count B is running pulse when the distance L ₂ and forward stroke It is equal to the number A. A distance Lo is provided between the vehicle detecting means D ₂ and the upper surface drying nozzle 2.
There are intervals. Furthermore, since the ascending speed of the upper surface drying nozzle 2 is finite, the distance Lu in which the traveling frame 1 moves in the time required for ascending has to be taken into consideration so that it does not come into contact with the vehicle body. Therefore, in order to move the upper surface drying nozzle 2 up and down, the traveling frame 1
Is not based on the actual distance L ₂ but on the basis of the vehicle height at the distance L ₃ obtained by subtracting the distance Lo and the distance Lu from the distance L ₂ . Therefore, the number of traveling pulses corresponding to the distance Lo and the distance Lu is subtracted from the number of traveling pulses B to calculate the number of traveling pulses X. Next, in step S _12, reads the stored content of the address X of the storage means M. The stored contents are data H corresponding to the vehicle height at the position of the number X of running pulses. Enter the lifting pulse signal in step S _13, if the not output signals are input upper limit detecting means D _6, if the upper surface drying nozzle 2 descends adds by one for each pulse signal, when the ascending one By subtraction, the number S of elevation pulses is obtained. In step S _14, is determined by the data read out in step S _12, the lifting pulse number Sn which correspond to the interval suitable for the drying process to compare the lifting pulse number S. The lifting pulse number Sn is a numerical value uniquely determined by the vehicle height, and the data H corresponding to the vehicle height
Is stored in advance so as to correspond to. Therefore,
Step S ₁₂ by the number of elevation pulses from the read data H Sn
Is determined. As a result of the comparison, the S <Sn if step S ₁₆ to step S ₁₅ if S> Sn, S = Sn
If in step S _17, advance, respectively. In step S _15, the solenoid valve 46, since the current flowing through the solenoid coil L ₄₆ is turned off, the non-excited. As a result, the hydraulic oil is supplied to the cylinder 4, and the upper surface drying nozzle 2 rises. In step S _16, the solenoid valve 46 is energized and the current flows through the solenoid coil L _46, hydraulic oil supplied to the cylinder 4 due to the weight of the drying nozzle 2, the display returns to the pressure vessel 47, the upper surface drying nozzle 2 descends.
At this time, since the check valve of the check valve 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 ascending. Moreover, as explained in step S _10, data H corresponding to the vehicle height is of a position ahead of the actual position of the traveling frame 1 is read. Further, as described above, the rising speed and the falling speed of the upper surface drying nozzle 2 are different. Therefore, the lowering of the upper surface drying nozzle 2 is performed after the number of running pulses corresponding to the distance L _D shown in FIG. 8 is input. Note that until the number of the running pulse is inputted corresponding to the distance L _D, if the process proceeds to step S _15, only the rise without lowering is performed. In step S _17, the solenoid valve 44, the current flows through the solenoid coil L _44,
Excited. Therefore, the stopping device 6 is operated and the piston rod 5 is stopped, so that the upper surface drying nozzle 2 is kept at a constant height. These steps S ₁₅ to S ₁₇ are repeated in step S ₁₈ until the output signal Yes of the start-position detecting means D _5.

[0029] Thus, in FIG. 8, when the traveling frame 1 reaches the position 1d from the position 1b, the upper surface drying nozzle 2 begins to rise from the height H _1. And height H ₂ ~
Via H ₅ reaches the height H _6. When the position 1e is reached, a descent is instructed, but the descent actually begins only after the distance L _D has been further advanced. Returning to the start position 1a,
The start-position detecting means D ₅ outputs the signal, driving the frame 1 is stopped, the upper surface drying nozzle 2 is returned to the upper limit position.

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

For example, the running pulse generating means D ₁ is not composed of a disk 30 having a plurality of convex protrusions on the outer periphery at equal intervals and a proximity switch 31 comprising a sensor coil. It can be constituted by a reed switch, and any encoder can be used. Further, when the traveling speed of the traveling frame 1 is constant, the travel pulse generator D ₁ may be a pulse generator having a constant cycle. Further, the number of photoelectric switches constituting the vehicle detection means D ₂ can be increased or decreased as necessary. In this case, if there is a risk of malfunction due to the proximity of each photoelectric switch, the light sources of the projectors La corresponding to the odd-numbered and even-numbered photoelectric switches are separately lit, and the photoelectric switch in each case is turned on. the combined output signal of the switch may be the output signal of the vehicle detection unit D _2.

Further, in this embodiment, an example is shown in which the present invention is applied to a vehicle body cleaning apparatus and used for measuring the vehicle height when controlling the raising / lowering operation of an upper surface drying nozzle. However, other cleaning processing, for example, brushing processing, It can also be used for washing and the like. Furthermore, it can be used when performing a process other than the cleaning process, for example, a wax process.

[0033] In the above embodiment, the running pulse generator D ₁ constitutes a traveling position detecting means of the present invention for detecting a running position of the traveling frame 1.
