Vylodyc / nfjou The invention relates to computing and information technology and is intended for automatic counting of products at their multi-station processing or in workshops of robotic production as peripheral sensors in automated systems of operational production,

The purpose of the invention is to increase the accuracy of the device by ensuring that it registers its products even in the case when one or several sensors failed to operate.

The drawing shows a block diagram of the device.

The device contains sensors 1, multiplexer 2, dividers 3 and 4 frequencies, shaper 5 pulses consisting of reacting organ 6 and comparator 7, elements AND 8 and 9, elements OR 10 and 11, elements 12 and 13 of the ban, elements 14 and 15, 16 delays, time delay elements 17 and 18, a one-shot 19, triggers 20 and 21, a memory block 22, an indication block 23 and a counter 24.

The device works as follows.

In the initial state, the first frequency divider 3 is set to the first (initial state), which provides the connection of the first sensor 1 via multiplexer 2 to the input of the shaper 5 pulses. The triggers 20 and 21 are set to the zero state, ensuring respectively the opening of the first prohibition element 12 and the closing of the second element 9.

When a product appears in front of the first sensor 1 at the output of the pulse generator 5, a pulse is formed which, after passing through the first prohibition element -12 and the first element OR 10, includes the first time element 17, in which the processing time of each item is entered processing positions, d-novibrator 19, the leading edge of the signal from the output of the first element 17 of the time lag goes to the inputs of the first element AND 8 and the second element 13 prohibition. Moreover, this signal is delayed by a single vibrator 19 in such a way that it is reliably blocked by a signal from the output of the driver 5 pulses.

the impulse from the one-shot output, Topa t9, passes through the first element AND 8, which, in turn, passes through the second element OR 11 and cocks the second element 18 in the delay time. After the time specified by the second time delay element 1B, a signal appears at its output, which, passing through the first element OR 10, turns on the first time delay element 17, and the frequency divider 3 enters the next state, allowing the connection of the next sensor 1 through multiplexer

2k shaper 5 pulses. The second time delay element 18, depending on the address to be set from the i output of the first divider 3 frequency, results in different time intervals, which are equal in duration to the time between two adjacent machining operations. If any sensor 1 fails, the signal to turn on the second shutter element 18 comes from the output of the single-oscillator 19, but through the second prohibition element 13 and through the second element OR 11. The first divider

The 3 frequencies upon the appearance of a pulse at the output of the second time delay element 18 transitions to the next state. If the sensor 1 did not work and the second prohibition element 13 triggered, then the signal from the output of the second prohibition element 13 will strobe the recording in the third delayed delay element 16. the block 22 of the memory of the number of the failed sensor 1, which is displayed in the block 23 of the display. At the same time, this pulse accumulates in the second divider 4 frequencies and if during the full response time of the first divider 3 frequencies the second divider 4 frequencies (i.e., the number of failed sensors turns out to be very large), then the second trigger 21 blocks the passage through the second element 9 counting signal from the output of the first divider

3 frequencies to the input of the counter 24. At the same time, the flip-flops 20 and 21 and the second divider 4 frequencies are reset to their initial state through the second element 15 of the signal delay.

If the second frequency divider 4 did not work, then the pulse from the output of the first frequency divider passes through

the second element And 9 to the input of the counter 24.

The delay elements 14, 15, and 16 timestamp the operation of the device.

The use of a multiplexer in the device made it possible to take into account when registering a product the fact of its sequential movement from one processing position to another. Moreover, the application in the device of the first element And the second element of the prohibition ensures the switching of the multiplexer. Even in the event of a sensor failure.
