Description

(5) DEVICE FOR COUNTING ISSUED. PRODUCTS

one

The invention relates to a computational and information technology and is intended for automatic counting of products in the automation of technological processes.

A device for metering products is known, comprising a sensor, an input amplifier, a power amplifier and an executive relay, the closing contact of which is connected to the pulse counter 1.

The drawback of the device is that it registers the number of the timing of its sensor. In order to determine, 5 dividing the amount of production, it is necessary to convert the meter readings into units of measurement of this product. For example, when several parts exit a stamp, 20 groups in a group need to multiply a sensor pulse on a group of parts by a number equal to the number of parts in a group.

The closest to the proposed technical entity is a device for counting piece goods, containing a sensor installed on the equipment, the output of which is connected to the input of the comparator, the output of which is connected to the input of the equipment operation control unit, and the first counter 2j.

However, this device only records the number of times its sensor has triggered. The device does not provide an opportunity to keep a record of production directly in units of measurement, which does not provide convenient information on current production indicators, but also complicates further information processing and leads to a decrease in counting accuracy.

The purpose of the invention is to improve the accuracy of the device by obtaining the ability to keep a record of production directly in units of measurement. 39 The goal is achieved by the fact that the output calculator, the sensor of which is connected through the comparator to the input of the equipment control unit, and the first estimator, has a second estimator, switch, AND block and pulse generator whose output is connected to the counting device. the inputs of the first and second counters, the installation input of the latter is connected to the comparator outgrowth, the outputs of the second counter through the switch are connected to the inputs of the block of elements I, the output of which is connected to the input pulses for generators. The drawing shows a functional diagram of the device. The device contains a sensor 1, a comparator 2, a unit 3 controlling the operation of the equipment, a second counter k, to mutator 5, a block 6 of elements And, a generator 7 of pulses and the first counter 8. The device works as follows. In the initial state, in the absence of parts passing through sensor 1, comparator 2 does not generate counting pulses. The second counter is filled in accordance with the coefficient set on switch 5. A signal is generated at the output of block 6 of the elements And which prevents the generation of pulses from the generator of 7 pulses. The first counter 8 is set to the initial state of the account. When a pulse appears at the output of the comparator 2, the second counter 4 is set to zero and at the output of the block 6 of the elements I, a potential appears that triggers the generator 7 of the pulses. The counting inputs of the estimators and 8 receive pulses until the second counter, k, counts the number of pulses, equal to the resampling coefficient. When the second counter 4 is filled to the same value as the conversion factor, the & prohibits the passage of pulses to the inputs of counters 4 and 8. 6 Thus, in the first counter 8, when a single pulse is detected at the output of comparator 2, a number coincides with the scaling factor installed on switch 5. When stamping parts (number of parts produced at each stroke press continuously with this device counts the true number of parts. By registering the sensor with the passing part and setting the coefficient in proportion to its weight, you can immediately get the meter reading Not in the number of datacom actuations, but in the total weight of the consumed material. Technical and economic effect of the device. It consists in the ability to maintain the output of the product directly in units of measurement. This provides convenient information on current production figures, as well as simplifies further information processing. The invention The device for counting the output of products, containing a sensor, the output of which through the comparator is connected to the input of the equipment control unit, and the first counter, which is different from the fact that, in order to improve the accuracy of the device, the second estimator, switch, unit Elements And a pulse generator, the output of which is connected to the counting inputs of the first and second counters, the installation input of the latter is connected to the output of the comparator, the outputs of the second counter through the switch are connected to the inputs of the unit elements And, the output of which is connected to the input of the pulse generator.
