The high-pressure air is guided and jetted to the high-pressure air jet nozzles installed at locations very close to the sensor transmitter / receiver surface. As an embodiment, a distributor (distributor) which also functions as a secondary compressed air tank, the same number of solenoid valves for compressed air as the number of ejection nozzles directly connected to the distributor, and connected to the ends of these valves Or use a pipe to the ejection nozzle installed in each sensor section, or use an ejection nozzle with an electromagnetic on-off valve for compressed air directly connected to each of the leading ends of the high-pressure compressed air piping system to many optical sensor sections. Or one of them.
Whichever embodiment is adopted, from the ejection nozzles installed in each of the optical sensor units existing in many places,
Spraying high-pressure compressed air all at once is a problem because of a sudden drop in pressure in the piping. Therefore, using a compressed air distribution controller, all the jets are ejected one by one at the time of each jet nozzle. It was decided to control the compressed air to be blown out over the nozzle.

力は終了し、ポンプの運転も止まる。Normally, a signal is sent to the remote power supply controller 11 via a communication line. From the remote power controller 11
When a power on / off signal is sent to the power switch 12 and a power on signal is sent to the remote power switch 12, the ATM
The power supply 10 is started up, and at the same time, a timer start signal is sent to the sensor section cleaning operation time setting timer 7 of the high pressure air supply system. Upon receiving the timer start signal, the sensor section cleaning operation time setting timer 7 changes the pump operation signal to the air compression pump 3.
At the same time, sends a distribution operation signal to the compressed air distribution controller 8. The compressed air pump 3 having received the pump operation signal starts the air compression operation, and sends the compressed air to the distributor 13 via the tank 4 and the filter 5. Further, the compressed air distribution controller 8 having received the distribution operation signal from the sensor section cleaning operation time setting timer 7 sends a series of sequence signals for opening and closing the electromagnetic on-off valve 6 to the compressed air distribution valve driving section 9. Upon receiving the sequence signal, the compressed air distribution valve driving unit 9 sequentially opens the electromagnetic on-off valves 6 directly connected to the compressed air distributor 13 at predetermined time intervals for a predetermined time. Send a signal. As can be clearly understood from the figure, the distribution valve driving unit 9 distributes the signal transmitted in series through one signal line to each of the same number of individual signal lines as the electromagnetic on-off valve, and Send to the on-off valve in parallel. In the case of this embodiment, the pressure of the compressed air slightly decreases in the pipe from the electromagnetic on-off valve 6 to the ejection nozzle 2, but it is enough to blow off dust attached to the optical sensor transmitter / receiver 1. . Since the tank 4 and the distributor 13 are provided, a sharp decrease in the pressure inside the high-pressure air supply system when the compressed air is ejected from the nozzle is considerably suppressed. When all the execution of the sequence signal for sequentially ejecting the compressed air from the compressed air distributor 13 to the plurality of optical sensors 1 is completed to the end, the sensor section cleaning operation time setting timer 7 performs the task as the set timer. Has been completed, the output of the operation signal to the compressed air pump 3 ends, and the operation of the pump also stops.

The only difference is that it is branched and connected to an electromagnetic on-off valve 6 directly connected to the ejection nozzle 2. The function of the compressed air storage (tank) inside the high pressure air supply system is far less than that of the first embodiment, and the pressure of compressed air inside the high pressure air supply system tends to decrease when compressed air is jetted. Therefore, it was directly connected to minimize the distance between the solenoid on-off valve 6 and the ejection nozzle 2 as much as possible.
