Packaging counting signal generating device

Abstract

A packaging counting signal generating device includes a counting signal sensor, a shift register, an adder, a decoder, an anti-interference threshold selector, an RS flip-flop, and an oscillator. The device can filter out single or continuous positive narrow pulse interference in several signal pulses, and can also filter out single or continuous negative narrow pulse interference in several signal pulses; the effect of filtering out interference pulses can be parallelized by changing the shift register unit The number of digits at the output end, or the size of the anti-interference upper threshold and anti-interference lower threshold in the interference threshold selector can be adjusted; the device can be applied to various production lines that need to generate digital signals.

Description

technical field [0001] The invention relates to the field of pulse signal generation and processing, in particular to a packaging count signal generation device. Background technique [0002] The photoelectric detection and counting technology mainly relies on the light emitted by the infrared sensor to detect particles such as medicine particles in the detection channel, and the receiving sensor generates pulse signals due to the occlusion of the particle detection objects for counting and recording. Due to the irregular shape of the particle detection object, the vibration of translation or slope sliding, the inversion of falling, etc., the counting pulse generated by the photoelectric sensor contains the leading edge and trailing edge shaking interference pulse. When it is directly used as the counting pulse, it will cause counting error. [0003] Linear array CCD / CMOS technology is a continuous counting method. The CCD / CMOS camera can scan and count the materials on the...

Due to the irregular shape of the particle detection object, the vibration of translation or slope sliding, the inversion of falling, etc., the counting pulse generated by the photoelectric sensor contains the leading edge and trailing edge shaking interference pulse. When it is directly used as the counting pulse, it will cause counting error

[0003] Linear array CCD / CMOS technology is a continuous counting method. The CCD / CMOS camera can scan and count the materials on the channel, and stop feeding when the set quantity is reached. Compared with infrared sensor technology, its counting accuracy and speed are improved. , but the cost is high
