Abstract

PURPOSE:To prevent damage to a vehicle by storing the moving distance of a side brush as locus data to make a car washing machine study the profile of the vehicle when the side surface of the vehicle is washed with the side brush, and moving a side nozzle along the profile of the vehicle when the vehicle is dried. CONSTITUTION:When the side surface of a vehicle is washed with a side brush, while the body of a car washing machine is advanced, the operation time of the car washing machine body in response to its position, and the moving distance of the side brush in its width direction detected by the first moving distance detection means 11 are input to a nozzle controller 12 provided on each of right and left sides every unit time, so as to be stored in a locus computation.storage unit 14 as locus data. Then the profile of the vehicle is therein studied. When the side surface of the vehicle is dried by a side nozzle, the operation time of the car washing machine body in response to its position is obtained from the retreat time of the car washing machine body. Then the position of the side nozzle 4 is controlled by a control unit 15 into which a feedback signal from the second moving distance detection means 13 is being input, while the stored locus data are aimed at as target values. Thus, the position of the side nozzle can be controlled along the slope of the vehicle without any contact with it, so that damage to the vehicle can be prevented.

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a car wash machine that is self-propelled and washes cars.

2. Description of the Related Art A conventional method of washing and drying the side of a car in this type of car wash machine will be described.

In order to wash and dry the side surfaces of the car, as shown in FIG. The brush 3 moves left and right in the direction of the arrow B and dries by the wind pressure that blows out the side of the car 2.A 1-ruride nozzle 4 is arranged, and a command 15 from the operation surface 5 as shown in FIG.
K': From the detection signal of the sensor system 6) from 1) to the controller 7, the sensor system 6 detects the sensor system 6.
The presence of tr is detected, and the control is heard from tj1.

Unable to cope with the inclination of L medium 2, the limit switch f- method Hibarimitsuto Suip is brought into contact with width 2! As a result of the fact that I was a junior high school student, I had one hair scratch on my painting surface (prefecture).

Kimitsu Ming solves the problem in t) of U-(gT>su,
7. Controls the reed nozzle non-contactly to prevent damage to the car in response to tilting. ``The purpose is to acquire and supply the latest car wash machines.''

Step 1 to Solve the Problems In order to solve the above problems, the present invention has a side nozzle that dries the car wash group main body from the front side in order from the front, and a side nozzle that moves left and right and dries the width side with wind pressure. Clean the side of the car with a brush that rotates over the sides of the car using the movable rlU.
5. Run the nli car wash machine to []fj near'j (

is detected and output to the side nozzle control nW device 12. 13 is a side nozzle pulse encoder which is attached to the side nozzle 4 as shown in FIG. 4 and is a second moving distance detection means for detecting the moving distance of the side nozzle 4. The moving path W1k is detected and output to the side nozzle system [11212].

The side nozzle control aBlff12 is a movement distance signal ct3 of the movement distance ρ of the side brush pulse encoder 11 and a movement v of the movement distance of the side nozzle pulse encoder 13.
J distance w1@@d is input, and a control signal e consisting of a left movement command, position hold or right movement command is output to the drive system of the side nozzle 4, and the side brush trajectory calculation/storage section C
It consists of a JX lower storage section (abbreviated as JX lower storage section) 14 and a side nozzle control section (hereinafter abbreviated as control section) 15.

In Fig. 3, rl is the distance from the brush center to the side of the car 2 when the side brush 3e is in operation, and in Fig. 5, r2
is the minimum required distance between the tip of the side nozzle 4 and the side surface of the width 2, and m is the distance between the mounting position of the side brush 3 and the side nozzle 4.

Before explaining the storage section 14 and the control section 15, the coordinates used in the following explanation will be explained with reference to FIG. In Figure 6,
X is the position where the side brush 3 starts to operate due to the operation of the motion detector (SBSSQL), and is set to 0.
The coordinate indicating the distance when the wooden body 1 moves, y is the V coordinate indicating the moving distance of the knife brush 3. In addition, the fixed distance in the X-axis direction between the side brush 3 and the side nozzle 4 is defined as J1, the traveling speed of the car wash machine main body 1 for a unit time α to the front F, and v1, and the backward speed for a unit time α to the rear E to be U. do.

As before, control of the side brush 3 to the left and right when the car wash main body 1 moves forward F is performed by the drive system of the upper brush 3 by balancing the repulsion between the brush and the cleaning surface caused by the rotation of the brush. Avoidance of the side mirror portion 2A of No. 2 is performed by setting a timer between traveling FRs.

The operation of the storage section 13 will be explained below based on the flowchart of FIG.

First, check whether the car wash machine main body 1 is in the predetermined position (initial position) (step 21), and if it is in the predetermined position, reset the timer time t and variable N (step 22).
