Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a type of car wash machine in which cleaning brushes and the like are arranged in a gate-shaped car wash main body, and the car body is automatically washed as the main body moves. [Prior art and its problems] Generally, this type of car wash machine has a large number of operating devices such as nozzles, motors, and air cylinders, so it is difficult to find abnormalities in the event of a failure or to check after repair. In this case, it is necessary to drive each actuating part and check the individual operations. However, in conventional car wash machines, the only way to drive these individual operating devices is to manually turn on electricity at the power distribution section, which requires considerable knowledge and skill from the operator. There was also a risk of malfunctions resulting in malfunctions. [Means for Solving the Problems] The present invention provides means for switching between a first mode in which a car wash can be performed and a second mode in which inspection work other than car wash is performed, and a means provided on the front of the car wash machine body. An input board that performs various inputs such as car wash operations, and an input board for each operating system such as the water system, drive system, and pneumatic system or individual operating equipment depending on the selected input to the input board in the second mode. The above-mentioned problem is solved by providing a control means for driving each time and giving a predetermined operation. In the following embodiment, the mode switching means corresponds to the key switch 57 described below, and therefore the first mode corresponds to the operation mode and the second mode corresponds to the management mode. [Function] This allows the mode switching means to
By switching to the mode and performing input operations on the input board on the front of the car wash machine, you can operate each operating system such as the water system, drive system, and pneumatic system, or each operating device individually, and detect abnormalities. You can find the location and check the operation after repair. [Example] Hereinafter, the example will be explained in detail based on the drawings.

In "4. Travel", a selection screen G is further displayed, and after receiving a selection of high speed, low speed, forward, or backward, the motor 50 is started to cause the main body 1 to travel.
In "5. Cycle", you can inspect and confirm the drive system sequence by going through the car wash sequence, rotating each brush and running the main body in sequence. (8) Based on screen C, a pneumatic system diagnosis routine is entered, and in this routine, the operations shown on selection screen F are selectively performed. In “1. Opening and closing the lock car”,
The air cylinder 46 is operated to open and close the rocker brushes 5, 5'. In "2. Side opening/closing", the air cylinders 38, 38' are operated to open and close the side brushes 3, 3'. In “3. Top elevation”,
The air cylinder 43 is operated to move the top brush 4 up and down. In "4. Nozzle raising/lowering", the air cylinder 48 is operated to raise/lower the blower nozzle 6.
In "5. Cycle", each air cylinder 38, 38', 40,
45, 45', and 50' to sequentially open, close, and raise and lower each brush and nozzle to inspect and confirm the pneumatic system sequence. As described above, each operating device can be operated individually by simply performing an input operation on the input board 52 according to the selection screen displayed on the display device. As shown in A, B, and C of the flowchart, the system is configured to give priority to the car wash so that it always detects that the key switch 57 is switched to the driving mode during the selection operation, cancels the selection screen display at any time, and shifts to the car wash routine. has been done. Furthermore, by pressing the return key 64, the user can return to the previous selection mode as shown in (b) and (c). [Effects of the Invention] The present invention is configured as described above, and each operating system or operating device can be operated individually by inputting information on the input board, so there is no need to operate complicated power distribution parts, etc. Even unskilled workers can easily find abnormalities and check operation after repair. Furthermore, since there is no need to specifically operate the power distribution section or mechanism section, there is no risk of failure or accident due to incorrect operation. In addition, operation can be confirmed simply by inputting data on the input board on the front of the car wash machine, and there is no need to configure the power distribution section to easily expose the power distribution section in anticipation of maintenance, which is required in the past.
It becomes possible to design a structure that focuses on maintenance such as earth leakage countermeasures. Furthermore, such inspection work is performed by switching the mode on the input board using a mode switching means, and the key for car washing operation can be given a different function for each mode and can be used for the same purpose, thereby eliminating the waste of arranging a large number of dedicated keys. This allows for an inexpensive configuration. Furthermore, since the car wash and inspection are performed in different modes, there is no risk of accidentally washing the car during the inspection, and inspection work can be carried out safely.
