Description

[Detailed description of the invention] [Industrial application field] This invention relates to a car wash machine of a type that is equipped with a car wash frame that travels as if straddling the car, and that washes the car body of the car using a processing device installed in the car wash frame. In particular, the present invention relates to a device that is provided with a truck that supports one of the front and rear wheels of a car and causes the car to run in a direction relative to the car wash frame, thereby reducing the travel distance of the car wash frame.

[Problem that the invention attempts to solve]

Generally, in this type of device, one of the front and rear wheels (usually the front wheel) of the car is supported by a trolley to drive the car, so if the car's handbrake is pulled or the car is left in gear, The cars could not be driven normally, and the cars would fall off the trolleys and fall, or the cars would be dragged and turned diagonally, making it impossible to wash the cars, and sometimes risking damage to the cars. .

[Means for solving problems]

This invention was made in response to these problems and has the following configuration.

The truck and the car wash frame are made to run independently in opposite directions, and the car is washed by a processing device provided in the car wash frame. The vehicle includes a means for detecting the running load of the truck, a means for notifying an abnormality, and a control means. In this control means, prior to washing the car, the trolley is run for a predetermined section,
At this time, it is determined whether or not the car can be washed based on the running load applied by the detection means, and if it is determined that the car can be washed, the car wash is continued, and if it is determined that the car can be washed, the car wash is stopped and the abnormality is notified by the notification means. Control.

[Effect]

As a result, even if a car that has been driven onto the trolley leaves the handbrake pulled or the gear engaged, the above-mentioned conditions can be corrected by driving the vehicle for a predetermined distance before washing the vehicle and using the running load of the trolley at that time. Since it detects this and stops the car wash, it is possible to prevent situations that could cause damage to the car.

FIG. 3 is a block diagram showing the control system of the above embodiment.

Numerals 15 and 16 are load current detection sensors provided in the circuit of the motor 6 of the bogie 4, which respectively detect the load current generated in the circuit of the motor 6 and output a signal. It is detected that the load is lower than the normal vehicle traction load by a certain amount due to the vehicle being unsupported by the vehicle, or the chain of the vehicle is broken, etc. Or, it detects that the handbrake is left on and the load is higher than normal by a certain level.

17 is a control unit built into the car wash frame 1;
Equipped with a microcomputer, the operation panel 14 and each of the detection sensors 8, 15, and
Based on the signal input from 16, operation commands are output to the car wash frame 1 and the trolley 4 to control a series of car wash operations.

FIG. 4 is a flowchart mainly showing the operation flow of the trolley 4 in the above embodiment, where A is the main flow;
B shows the running test routine executed in step 9 of this main flow. The operation of the above embodiment will be explained below based on this figure.

In the following description, the movement of the car wash frame 1 and the truck 4 in the direction toward the fixed unit 12 will be referred to as backward movement, and the opposite movement will be referred to as forward movement (see FIGS. 1 and 2).

When the car wash frame 1 is energized, the start position detection sensor 8 first detects whether the trolley 4 is at a predetermined start position at the front end of the rail.
(1), If by any chance it is not in the designated position, drive the motor 6 to move the trolley 4 forward (2). Accordingly, when the start position detection sensor 8 detects that the trolley 4 has reached a predetermined position (3), the running of the trolley 4 is stopped (4).
On the other hand, the trolley chain is broken or detached and the trolley does not run, and the control unit 17 detects that the trolley 4 has not reached the predetermined position even after a certain period of time has elapsed.
(5), it is determined that there is some kind of abnormality in the trolley 4, and an abnormality display is displayed on the output section of the operation panel 14 saying "The trolley is abnormal, please check" (6), and all It stops operating (7) and waits for reset.

When it is confirmed in step 1 or 3 that the trolley 4 is at the predetermined starting position, the system waits for a car wash input (8). Here, when there is a car wash input on the operation panel 14, a driving test routine is first performed (9),
Check whether the car is correctly loaded onto the trolley 4. When the driving test routine (9) is completed and it is confirmed that the trolley 4 is in a state where it can normally tow a car, the car washing operation in the car wash frame 1 is started, and the trolley 4 waits for an operation command from the control unit 17 ( Ten).

When the car wash starts, the car wash frame 1 moves forward, and when the vertical brush 3 comes into contact with the front of the car, the car wash frame 1 stops running, and the vertical brush 3 is rotated to wash the front of the car.

When the vertical brush 3 finishes washing the front of the car in the car wash frame 1, a command to start running is output to the trolley 4 (10), and it is confirmed whether the trolley 4 is moving forward or backward according to the car wash program being executed. Back (11), here the trolley 4 is moved backward (12). In this way, as the trolley 4 moves backward, the side and top surfaces of the vehicle are cleaned by the processing devices including the vertical brush 3 in the car wash frame 1.

Here, if high-speed car wash is set on the operation panel 14, the car wash frame 1 moves forward as the trolley 4 moves backward to increase the processing speed of the processing device for the car, and if low-speed car wash is set, the trolley 4 reaches the travel limit position and stops moving backward in the following step (15), and then moves the car wash frame 1 forward to continue washing the car.

When the trolley 4 moves backward for a predetermined period of time and detects that the trolley 4 has reached near its travel limit (14), the trolley 4
Stop running (15). After truck 4 stops running,
Whether the running car wash is finished or not, that is, if the car wash 4 is completed or not,
It is confirmed whether or not it is necessary to run (16), and since the forward step is only completed here, the same operation is repeated from step (10). In the next operation, the trolley 4 will move forward (13) in response to the travel start command, while the car wash frame 1 will move backward.

The car wash progresses in this way, and if the completion of the operation is confirmed in step (16), the process returns.

Next, the driving test routine shown in FIG. 4B will be explained. First, the truck 4 is moved backwards (21), and during this time, the load current detection sensors 15 and 16 detect underload or overload (22) and (23), and if there is an abnormal output from the sensors 15 and 16, An abnormality display saying "Load abnormality, please check" is displayed on the operation panel 14 (24) (25), and all car washing operations are stopped and the system waits for reset (26).

When the test run is completed for the required time without detecting any abnormality (27), the backward movement of the truck 4 is stopped (28), and then the truck 4 is moved forward (29). As the trolley 4 moves forward, when the start position detection sensor 8 detects that the trolley 4 has returned to the predetermined starting position (30), the running of the trolley 4 is stopped (31) and this routine ends.

In the unlikely event that a certain amount of time passes without the start position being detected in step (30) (32), it will be determined that there is an abnormality in the trolley and a message will be displayed saying "Trigger is abnormal. Please check." 33), all operations are stopped and the system waits for reset (34).

As described above, according to this embodiment, the operation panel 1
When there is a car wash input in step 4, a running test routine is first executed to make the trolley 4 run for a predetermined section.The running load of the trolley 4 at this time is detected by the load current detection sensors 15 and 16, and it is determined whether there is any load abnormality. If detected, the car wash is stopped and an error message is displayed on the operation panel 14.

[Effects of the invention] This invention is constructed as described above, and detects the condition of the car entering the vehicle based on the running load of the trolley, and if an abnormality is detected, the car wash is stopped, thereby preventing accidental damage to the car. It can be used safely without any risk of harm.
