Abstract

PURPOSE: To make it possible to exactly executing the counting which is free from a counting error, by putting two filaments to one counted object by use of a contactless detector, and making it generate one signal through the latch circuit.
CONSTITUTION: When a bottle approaches the photo projector and detector and shuts off a light beam of the photo projecting and detecting part A, the photoelectric switch A6 outputs "1" and B7 outputs "0". Accordingly, the AND circuit 12 outputs "1", and the AND circuit 13 outputs "0". FF14 is set by an output "1" of the circuit 12 and an output "0" of the circuit 13, and outputs "1" to the counter. The bottle moves forward, both the switches A6 and B7 shut off the light beam, the outputs become both "1", and FF14 is not varied but outputs "1". Subsequently, when the switch A6 detects a light beam and B7 shuts if off, the circuit 13 outputs "1" and resets FF14. When the bottle has finished passing in the end, FF14 is not varied even if both the switches A6 and B7 detect a light beam. In this way, the moment only the switch A6 has shut off a light beam, the latch circuit 8 outputs "1" to the counter, and it is returned to "0" when the bottle has passed and only B7 has shut off a light beam. Even if the bottle moves during the said time, the output is not varied erroneously.
