Abstract

The invention relates to information and computing technology and can be used as peripheral sensors of production control systems. The purpose of the invention is to increase the accuracy of the device. The device for counting the products carried by the conveyor contains the first and second sensors 1 and 2, the first and second pulse shapers 3 and 4, the first and second RS triggers 5 and 6, the first, second and third elements 7 7, one - the vibrator 10, the first and second delay elements 11 and 12, the reversible counter 13, the pulse generator 14 and the third and fourth delay elements 15 and 16. The device carries out the counting information synchronized from the pulse generator, which allows it to be used for recording products for high performance th equipment, thus eliminating glitches on the occurrence of products on both channels registration. 1 an. f (L

Description

The invention relates to

| computational and computer technology and 1can be used as nernfernynye sensors systems operational management production. A: The purpose of the invention is to improve the accuracy of the device’s operation. At the same time, a functional diagram is shown;

 The device contains - the first 1 and the second 2 sensors - the first 3 to the second 4 pulse formers of the first 5 and | in the first RS-flip-flop, the first 7, the second, the 8 and the third 9 elements. And ,, odnovib: eator She first P and second 12 elapsed; From the reversible counter 3, the generator of 14 pulses and the third 5 and Chetzar; There are 16 delay elements.

The device works as follows - Float about ™ azo.

In the initial state, the wriggers 5 and () set the state, ensuring the blocking of the first 7 and second elements AND, When the signal arrives from the catch 1 signal 1, its leading edge is detected; 3 n includes frigger 5o When a pulse of 14 ksushu.psa is received from the generator. He passes the first element of And 7 and Zadeh. ikbm on the element i 1 for. Direct access of the reverse counter 13 reverse account, at the same time, this signal is the first reset; the first trigger 5 s is: one state. Similarly, it is f) ra to: h.trade-hedeli., which 1 | registrar ts by the second sensor 2, the difference is in TOMj that C1 signal is fed to the input of the reverse ci.iera reversing counter 13,

In the case of jets with the sensors 1 and 2 formed simultaneously with the signals, then with a pulse of more than 5 pulses, the first inputs of the first 7 n second 8 elements AND the RS-triggers 5 k ebra- C | b are reset to their original state the outputs of the first 7 and second 8 elements And, while on 0 1: there is a third element And 9 and at the output of the tweeter 10, a signal appears that prohibits the accumulation of buttons in the counter 13. Duration of control smg ala, Forging with a single vibrator lOj should be

  them, yr

Where

 oA pulse duration of one-shot 10;

im - generator pulse duration 14 | delay elements 1 1

 and. 12,

The choice of the duration of the signal generated by the iO single-shot is determined by TeMj that, when both signals 1 and 2 receive signals on both sensors 1 and 2, the state of the reversible counter 13 must not change,

Thus, the device is synchronized from the generator and the I-th in the aperture of the counting information, which allows it to be used for registrachdan products on high-performance equipment, including failures in the appearance of products on both channels
