Description

p1 The invention relates to computing and information technology and is intended for use in automated operational control systems for software counting of sold products in various industries, such as packaging machines and lines. A device for counting piece products is known, containing a counting pulse clock, input driver, counting chips, decoders, comparison circuits, and logic elements. With the help of zshatchikov, the counting program in each digit in the decimal code is set and stored until the end of its processing. Upon reaching a specified number of products in, each bit, the signals from the decoders and zshatchikov programs generate a signal for working out the program l. . The known device does not provide for the counting of items when they are returned or reversed, as well as the automatic setting of counting programs from external code devices or setters, which limits the operational capabilities of the device. In addition, due to the large number of functional connections of the equipment, as well as due to failures, occurring at the moments of simultaneous program processing in one or several bits of the counter, the reliability of the device is reduced. It is also known a device for programmatically counting piece goods, containing a counting pulse sensor, an input driver, counting decades with indicia, program sets and decoders, an amplifier, a program counter, an OR element, a trigger, an output driver, an output control mode switch the signal, the command body, the channel of the remote control of the output signal, the channel of external action, the channel for connecting the higher bits of the counter, and the master of the output signal. The setter sets the counting program in each digit of the counter in the decimal code, which is stored in it until the end of its development. Upon reaching a predetermined number of products in each of the bits of the discharge decoder, a signal is generated for the development of the program, which is fed to the elements of the output signal. The counting program is entered in a decimal code for each bit using the program setters and compared with the pulse number code at the output of the decryption code of the corresponding decade of the I counter. Operational capabilities of this device are limited due to the existence of the equipment. The closest to the proposed technical entity is a device for software counting piece goods, containing a product sensor, pulse counter, the first outputs of the counting decades of which are connected to the inputs of the corresponding display elements, And elements and memory elements h. The drawbacks of the device are the impossibility of counting items when they are returned or reversed, which limits the scope of application of the device, as well as the complexity caused by the presence of additional memory elements. The purpose of the invention is to expand the scope and simplify the device. This goal is achieved by TeMi that a device for counting piece goods containing a product sensor, a pulse counter, the first outputs of the counting decades of which are connected to the inputs of the corresponding display elements, a sensor for the direction of movement of the products, a switch and an OR-NOT element whose output is connected to the first input of the switch, to the second and third inputs of which are connected the outputs respectively of the product sensor and the sensor of the movement of the products, the first and second outputs of the switch are connected to the input The meter counters, the outputs of the counting decades of which are connected to the inputs of the element OR NOT, the installation inputs of the device program are the installation inputs of the counting decades, the output of the device is the third output of the switch, and the counting decades are reversible. The drawing shows a functional diagram of the device. The device for program account of the products contains the sensor 1 of the products, the sensor 2 of the direction of movement of the product, the switch 3, the counting decades of the 4 pulse counters, the elements 5 ind. The data, the element OR-NOT 6 and the execution unit 7. The information inputs 8 are the inputs of the device for recording the value of the programmable information information of the counting decades 4, respectively. The device input 9 is connected to the set inputs of the counting decades 4 and serves to accommodate the recording of the value of the program being set. Sensor 2 of the direction of movement of the products generates a signal corresponding to the direct or reverse movement of the product. This may be the direction of rotation signal of the engine.

a control conveyor or conveyor, or a group of sensors installed and turned on appropriately and forming a signal for the direction of movement of the product.

The switch 3 can be made according to well-known schemes, and contains elements 10-12, having direct or inverse inputs.

 The counting decades 4 counted the products from the signals from sensor 1 when moving them both in the forward direction and in the opposite direction, and also ensured that the value of nporpciMM was received and stored from external devices.

The program value is recorded in the counting decades 4 by the information inputs 8 by a recording signal on the device input 9, which can be sent from control devices or from the execution unit 7. The counting decades 4 can be performed on integrated circuits of the K155, K133 series and so on. e., for example counters IB6.

Executive unit 7 is either a signal distributor, which switches external sources of information, arrives at information inputs of 8 counting decades 4 and / or a counter of the number of worked programs, or a switch (relay) for switching off the actuator, for example, a drive.

The device works as follows.

In the initial state, signals from the output of the sensor 1 of the products are not received. Sensor 2 generates a signal corresponding to the reverse movement of the product.

In the counting decades 4, any information can be found, and at the information inputs of the decades the information from the programs offered for execution appears periodically (from the information highway through the device 8 inputs). For the execution of one of the programs for the recording signal from the input 9 of the device in the counting decades 4, the selected program is recorded. When moving the first product, the sensor 2 generates a signal on which the switch 3 connects the counting pulses of the sensor 1 and the subtractive input of the counting decade 4, since the product moves in the forward direction1 And 10 and 12 elements are opened and the And 11 element of switch 3 is closed.

During the reverse movement of the product according to the signal from the sensor 2 of the direction of movement of the product, the switch 3 connects the counting pulses of the sensor 1 to add in the decades 4. At the same time, the element 11 is opened and the elements 10 and 12 are closed.

Thus, during the operation of the device, the pulses from the product sensor 1 during the forward movement of the product subtract 4 program values from the recorded in the counting decades, and during the reverse movement of the product are added to the information available in the decades.

Consequently, the signals in sensor 1 measure state in dex 4, the information of which is monitored by the corresponding display elements 5.

In the process of subtracting pulses in each 4 steps, when the O value reaches the output of the OR-NOT 6 element, the signal H appears, which arrives at the first input of the switch 3. The last one (the elements 10 and 12 are open and the element 11 is closed) forms the end of the signal program, which enters the execution unit 7 for the organization of control operations. After that, in the counting decades 4, the next program is entered in the same way as described.

Thus, during operation of the device, the program is recorded directly into the counting decades 4 from the information inputs and the end of the program is always generated after the last product passes and in the zero state of the decades 4.

If during the program account of products there will be a return of products, i.e. their reverse movement, the device ensures their actual accounting without failure.

In addition, the device also provides a more reliable and convenient on-line control in the process of working out the program, since at any time there is information about the number of products that need to be processed before dialing the full task. This allows increased operational capabilities of the device.

The rational setting of programs with its value recorded in the counter eliminates the need to store it in additional blocks during its processing, which significantly reduces the amount of equipment for implementing the information storage scheme, as well as code comparison circuits and, therefore, increases the reliability of the device as a whole.

Consequently, the proposed device is safer and simpler in design compared to known devices, and, in addition, its operational capabilities are improved, which allows it to be used for software counting in production lines with forward and backward movement of products in the area of technological control.
