Abstract

PURPOSE:To prevent door mirrors from damages due to side brushes in a car washing machine by spacing the side brushes from positions of door mirrors sidewise of a vehicle during reciprocation of the vehicle for washing. CONSTITUTION:After the beginning of car washing, when a predetermined first set time T1 has elapsed from point 7A, i.e. when side brushes 7 come to positions 7B, the side brushes 7 move outward sideways to part from the sides of a vehicle V. Next, when a second set time T2 has elapsed after the beginning of outward sidewise movement of the side brushes 7, the side brushes 7 begin to approach the vehicle V. In the backward movement of the vehicle, the side brushes are parted from the sides of the vehicle at the positions of door mirrors in the time reversely calculated from the measured time in the forward movement so that the side brushes can be securely prevented from contacting the door mirrors.

The blower nozzle 32 is raised and lowered by a lifting means (not shown) in accordance with the height of the vehicle to be dried.

Next, the operation of the rotary brush device B in the cleaning process will be explained. The brushing cleaning operation of the rotary brush device B is completed by one reciprocating movement of the portal frame 2. Therefore, first, with reference to FIGS. 3 and 4, the gate-shaped frame 2
The following describes the operation when moving to and fro.

When the gate-shaped frame 2 starts to move forward, both the 8-id brushes 7 are located at the innermost position, and when the gate-shaped frame 2 comes to the position where it comes into sliding contact with the front surface of the vehicle V as the gate-shaped frame 2 moves back and forth, they are cleaned while cleaning the front surface. First move outward @1-1 and then move inward to wash the entire side surface of the vehicle V. When this side brush 7 comes to the position shown by 7A, the top brush 6
The reed is at the position shown by 6A in FIG. 3, contacts the front windshield of the vehicle and rotates rearward along the outbound direction 8, and the contact element 21 is opposed to the magnet (20) and the detection signal is sent to the electronic circuit. is input. When a predetermined first set time T has elapsed since this detection signal was input, the vehicle moves away from the side of the vehicle V. Next, when the second set time T2 has elapsed since the start of the outward movement of the side brush 7, the side brush 7 starts its full approach motion toward the vehicle V.

The first set time T is the top brush 6 and the side brush 7.
The time from when the top brush 6 reaches the set position of the door mirror DM, that is, near the front window part, until the side brush 7 comes to a position close to the door mirror DM, is calculated according to the distance between the gate frame 20 and the door mirror DM. It is set based on speed. Further, the second set time T2 is preset as a sufficient time for the side brush 7 to separate from and pass the door mirror DM.

After the second set time has elapsed, the side brush 7 comes close to the side surface of the vehicle V and thoroughly cleans the side surface, and the gate-shaped frame 2 passes the vehicle v1 and reaches the closed position shown by 7C. . After the second set time T2 has elapsed, the time T3 to reach the position indicated by position 7C varies depending on the length of the vehicle V, and the time T3 is measured by an electronic circuit.

In FIG. 5, when the gate-shaped frame 2 is going back, when the side brush detects the entire rear surface of the vehicle V, the gate-shaped frame 2 temporarily stops its going-around operation, and the side brush 7 moves outward. . The time T4 from when the portal frame 2 starts deflecting until it once stops is measured. Next, the gate-shaped frame 2 starts to go back and moves close to the side of the side-grazing vehicle V, and the time 1. It has also been measured.

A preset time T6 is determined from the measurement time T3 during the outgoing trip.
A time T7 is set by subtracting the above measurement time T.
, , T, becomes equal to T7 (T4+T,=T7), the side brush 7 is operated to move away from the side of the vehicle V. The set time is set based on the traveling speed of the portal frame 2 and the moving speed of the side brush 7. When the second set time T2 has elapsed after the start of the separation operation of the side brush 7, the side brush 7 is moved close to the side surface of the vehicle V, and after that, the side brush 1 moves while cleaning the side surface of the vehicle V, Return to original position.

In this way, the side brush 7 can clean the side of the vehicle V without coming into contact with the door mirror DM when the portal frame 2 is moving forward or backward, and damage to the door mirror DM is prevented. Ru.

In the above embodiment, one round trip of the portal frame 2 results in one
Although we have described a car wash machine that completes a wash cycle, the invention can also be implemented in connection with a car wash machine that completes one wash cycle with yet another forward movement of the portal frame 2, in which case In this case, the same NTh behavior on the operating side as in the first forward movement should be maintained.

As described above, according to the present invention, after the second set time of the gate-shaped frame has elapsed, the side brush is moved close to the side of the vehicle, and the time from then until the sexual movement of the gate-shaped frame stops is measured, and In the frame practice, when the portal frame goes around for a time corresponding to a predetermined time subtracted from the measurement time, the side brush is operated to move away from the side of the vehicle for a second set time, and After the second set time has elapsed, the side brushes are operated close to the side of the vehicle, so when traveling, the brushes are rotated upwards at the front windshield of the vehicle, so that they almost align with the front windshield. The side brush is moved away from the side of the vehicle by detecting the door mirror in the position where the door mirror is located, and moving the side brush away from the side of the vehicle so as not to contact the door mirror. Since the side brushes are moved away from the side brushes, it is possible to reliably prevent the side brushes from coming into contact with the door mirrors, and it is possible to prevent the door mirrors from being damaged due to contact with the side brushes.
