(54) DEVICE FOR PRODUCT ACCOUNT

one

The invention relates to the automation of production accounting. and can be used in automated systems of operational control of accounting and control of production processes, for example, rolling production.

A device for counting piece goods is known, which contains a trigger counter / associated with display units, a pulse shaper, a reset unit, a computing unit, and key elements. In this device, the signals of the closing contact in the trigger cells of the counter accumulate the number of pulses corresponding to the number of products, and the computing unit performs accounting for a given program using the control | her computer Ts.

However, this device can keep records only in the number-pulse code and, moreover, due to the presence of contact control, it has insufficient accuracy and reliability. The closest in technical essence to the present invention is a device for counting products, containing a pulse generator, a pulse shaper, an information input unit, elements OR, AND, prohibition elements, a switchboard and a decoder 2.

According to the scheme of this device, the Start signal through the OR element and the driver, the switch connects the AND element of the first digit of the counter and the prohibition elements of the first decimal digit, from the output of which the specified code of the digit of this bit goes to

10 a decoder, which rewrites this number in the additional code in a trigger counter, after which the signal from the input unit code buses is removed, and by the enable signal from the element

15 OR through the prohibition element, the generator pulses are passed to the input of the first digit of the counter (through the AND element) and to the input of another counter.

Repeat signal: trigger knowledge

The counter 20 prevents the generator from passing pulses and switches the switch to the census of information of the next bit of the input block. The census of the entire number into the counter is carried out.

25 for 10 p clock cycles, where n is the number of counter bits.

Due to the asynchronous operation of the generator and the element OR, the first pulse in each discharge can be formed

30 with irregular parameters (as

both in amplitude and in duration) and recorded only in one of the counters, which leads to a failure of the device and accounting errors. In addition, when transferring numbers containing one or several zeros in any bit, when the census of information after zero to higher bits in the known scheme is stopped and some of the information (without manual intervention using the switch) is unrecorded, which reduces the accuracy of counting and characterizes lack of reliability of the device. The device has a manual data entry unit, which reduces the degree of automation of the process, and the speed of the device.

Thus, the known device has insufficient accuracy and speed, and its field of application on modern high-speed equipment is limited.

The purpose of the invention is to improve the accuracy and speed of the device.

This goal is achieved by the fact that a device for counting products containing a pulse generator, pulse counters, a pulse shaper, an information input unit and OR elements are inserted into memory of the device input connected to the first input of the pulse shaper, the output of which is connected to the first pulse counter via the pulse generator The group of outputs of which is connected to the inputs of the information input unit, the first input of which is connected to the first input of the second pulse counter, the outputs of which are connected s with the first inputs of the memory elements, the outputs of the last; they are connected to the first inputs of the OR elements, the second inputs of which are connected to other outputs of the information input unit; the outputs of the OR elements are connected to other inputs of the second pulse counter; the output of the first pulse counter is connected to the second inputs pulse former and memory elements. .

The drawing shows a functional diagram of the device for counting products.

The device comprises a pulse generator 1, a first counter 2 pulses, a pulse shaper 3, an information input block 4, elements OR 5, a second counter 6 pulses and elements 7. .Ifkm ty.

The output of the pulse generator 1 is connected to the input of the first counter of 2 pulses, one of the outputs of which is connected to the installation inputs. the driver of 3 pulses and the elements -7 are us, and the code outputs of the first. c, the ruler of 2 pulses are connected to the corresponding code inputs of the random elements of the task of the information input unit 4, the same inputs of all the bits of the task are connected in parallel, the output of the driver of the 3 pulses is connected to the control input of the pulse generator 1; the output of the first-set reference element of the information input block 4 is connected to the input of the first discharge of the second counter; 6 pulses directly the outputs of the remaining discharge elements es OR elements 5 are connected to the inputs of respective bits of second counter 6 pulses. The outputs of the bits of the second counter 6 impulses, except the last, are connected to the first inputs, the memory elements 7, the output of each of which is connected to the first input of the element OR 5 subsequent discharge.

The first counter 2 pulses in the process of filling it with pulses from the pulse generator 1 to the full capacity (for example, up to ten) generates a number-pulse code at the code outputs,

The bit element of the task in the information input unit 4 can be, for example, a code switch (mainly contactless) providing the connection of the code buses of the first counter corresponding to the given code to 2 outputs of this bit of the information input unit 4. At the same time, in one cycle of operation of the first counter, the output of each bit of the element of the information input unit 4 passes a number-pulse code equal in value to that given by this element.

The product counting device operates as follows.

In block 4 of the input information is set the value of the parameter piece goods.

When the Start command arrives at the input of the imager of 3 pulses, the signal from its output turns on the generator of 1 pulses, the pulses from which begin to arrive at the input of the first counter of 2 pulses. When the tenth pulse arrives at its input from a single output through a pulse shaper of 3 pulses, it turns off the generator

1 pulses.

I

In the process of counting a series of ten

the pulses of the first counter 2 pulses of the value of the number-pulse codes at its code outputs go to the information input unit 4, the bit elements of which specify each number of pulses equal to the cortex specified in it. These pulses through the corresponding bit elements OR 5 in parallel arrive at the corresponding inputs of the bits of the second counter 6 pulses for summing up with the information contained in them. Record information in all digits of the second.
