Description

The invention relates to the automatic accounting of piece products and can be used in various fields of national economy, in particular as peripheral sensors in the process control system of discrete production.

The purpose of the invention is to improve the accuracy of the account.

The drawing shows a block diagram of the device.

The device contains: sensor 1, driver 2 pulses, integrator 3, element 4, synchronization unit 5, key 6, analog-to-digital converter 7, memory element 8, block 9 keys, operating memory unit 10, digital comparators 11, first element OR 12 block of elements OR 13, counters 14, trigger 15, prohibition element 16, reversible counter 17, block 18 of elements AND, second element OR 19, inputs 20 and 21 of the device _; the detector 22, the delay element 23, the third element OR 24. The synchronization unit 5 may contain, for example, delay elements 25-27 and the differentiating element 28.

The device works as follows.

When a pulse arrives from sensor 1, pulse former 2 generates a pulse during which integrator 3 integrates pulse from sensor 1. Integrator 3 integrates the pulse from sensor 1, thereby determining the interaction energy of the part with the characteristic field of sensor I. When the pulse at the driver's output disappears 2 pulses, the integrator 3 stops the integration, and through the switched on key 6, the voltage from the output of the integrator 3 is fed to

the input of the converter 7. At the same time, it is started by a pulse from the output of the HE 4 element of the synchronization unit 5, which after a time longer

5 processing information by the converter 7, includes the keys of the block 9 and writes to the memory element 8. The status of the outputs of the converter 7. The code received from the information inputs of digital comparators 11 from the output of converter 7 does not generate a pulse at the output of any digital comparator, since all the inputs of the setpoint are

15 zeros. And after the time required for comparing, the impulse from the output of the synchronization unit 5 is fed through the BANNER element 16 to the input of the reversing counter 17 and turns on

20 alarm 22, signaling the stop of the conveyor. At the same time, the integrator is reset to zero. At the same time, the worker must recognize the part and by acting on the tire

25 20 using the button to give a command to the device that this item is subject to counting. At the same time, through the corresponding element I of block 18, a pulse comes to overwrite the information from the outputs of memory block 8 into the memory of the corresponding random access memory 10 and, after a time delay, the memory block 8 is reset to its original state. Selection

_{35 of the} operational storage unit 10 is determined by the state of the counter 17, which can be performed on counters of the type 564IE9, where the output code is represented as a moving unit from discharge to discharge at each counting pulse. Moreover, this counter must perform not only addition, but also subtraction, i.e. be reversible. When _{4 are} applied to the tire (by signal) in one

From counters 14, the first unit is recorded corresponding to the first part. Further, in this counter, information is accumulated about parts having the same code at the output of converter 7 with a certain tolerance range, which are determined by the initial state of block 10. At the same time, the alarm does not work because the generated pulse from the output of one of the comparators 11 through the element OR 1 2 to the input of the trigger 15, the operation of which leads to blocking the passage of a pulse from the third output of the synchronization unit 5, and the signal from the output of the element OR 12 resetting 1201854

em in the initial state element 8

of memory. Rewriting in one of the blocks

10 is not made.

When a situation arises when none of the comparators have failed, the alarm is activated, and the conveyor is stopped. At the same time, the worker must again understand the situation. The situation can be recognized automatically by other methods, namely, by automatically controlling the geometry of the product, with the device being fully automated 15, and tires 20 and 21 are connected to the outputs of the control device.
