Abstract

PURPOSE:To monitor choking of a nozzle without producing a change and an interference from the outside, by a method wherein a change in a sound wave signal of a jet sound from a nozzle is always monitored. CONSTITUTION:A paint 3 in a tank 2 is fed by pressure to a spray gun 1 via a valve 8 and a line 9 by means of a pump 5 driven by high-pressure air from an air source 6, and is jetted through a nozzle 12. A microphone 13 picks up a jet sound produced through the nozzle 12, and feeds it to a filter 16. The filter 16 causes only a set frequency band to pass, and an amplifier 17 generates an output voltage V proportional to a sound volume. If a reference voltage Vs of a reference voltage generating circuit V is set so that it is lower than an output voltage V at a normal painting time or at the time when there is no choking of a nozzle, the voltages are brought into Vs<V at the normal painting time, and a comparison circuit 18 generates no output. If the nozzle 12 is choked, and paint is reduced in a jet amount, a sound wave signal is decreased in a sound volume, and the amplifier 17 is reduced in the output voltage V. Thus, when the voltages are brought into Vs> V, the comparison circuit 18 outputs a nozzle choke detecting signal, and actuates an alarm circuit 15 and the like via an output circuit 20.
