The invention relates to software counting devices and can be used to count manufactured piece products in various industries, for example, on packaging machines and lines.

There are known devices for counting 1.1-gp boxed products according to a program installed by a sampler, containing a sensor for calculating arrays, a gauge, for calculating decades, a program or product group counter, a display board and an output command authority 1 |. Its disadvantage is the inability to control the duration of the output signal.

The closest to the invention is a device for programmatically counting piece goods, containing a sensor connected through an input shaper to the first decade counting counter connected to the next decade counting by them, each of which is connected to a corresponding decoder, program master and indicator, amplifier switch and counter 2 connected to the command body. However, this device cannot be used on automated equipment installed in automation ovannoy technological control system iropessami.

The purpose of the invention is to increase the reliability of the device.

This is achieved by introducing a trigger and an OR element into the device, and the output of each decoder is connected to one of the inputs of the OR element and to the input of the output signal generator, the output of which through the switch is connected to another input of the OR element, whose output is through the trigger connected to the input of the amplifier .

In addition, the device is set to set the duration of the output signal connected to the driver output signal.

The drawing shows a block diagram of the proposed device.

It contains sensor 1 1 pulse, driver 2 input signal, counting decades 3 with indicators 4, control points

Claims (2)

programs 5 and decoders 6, amplifier 7, run-off counter 8, element OR 9, trigger 10, output driver, output control mode switch 12, command unit 13, remote control output channel 14, external input channel 15, channel 16 connecting the higher bits of the counter and the setpoint 17 of the output signal duration. Sensor 1 generates counting pulses, which through shaper 2 arrive at the first recalculation decade 3. The counting indication is performed by indicator 4. The setting device 5 sets the counting program: 5 at the first decade — units of a given number of items, and the second at ten, at the third — hundreds etc. When the specified number of products is reached by the decoder 6, a program processing signal is generated, the input is one of the inputs of the OR element 9 and the input of the output signal generator 11, as well as the input of the counter 8. The output of the OR element 9 is connected to input ohm countable trigger generator 10. And determines temporary parametryis output pulse. In this case, the trigger 10 generates an output signal, the residence time of the trigger in a steady state is due to the interval between the signals arriving at the counting input. The output signal of the program run, taken from the output of the trigger 10, through the amplifier 7 enters the comaid organ 13, which controls the circuit of the channel 5 of external action. The switch 12 provides the selection of the control mode 25 by the output signal of the program run. In this case, there are three modes of operation: self-control, remote control and switching. In the self-control mode, the program processing signal produced by decoders 6 at the time of counting by decade 3 of a given number of products, excites the command organ. 13 through the element OR 9, the counting trigger 10 35 and the amplifier 7. At the same time, there is a signal at the output of the trigger. The removal of the excitation from the command body 13 is carried out by a program testing signal passing through the driver 11, the switch 12 and the element OR 9. The trigger 10 is switched, and the signal at its output disappears. A control device 17 can be connected to the control input of the imaging unit 11. The imaging unit 11 can be implemented as a delay element. 30 45 In the remote control mode, the excitation from the command body 13 is picked up by a signal on channel 14 through the element OR 9. At the output of the trigger 10, a signal appears. Subsequently, the command body 13 is excited by a program testing signal coming in through the OR 9 element from the decoders 6. In the switching mode, the switch 12 turns off the output of the imaging unit 11 from the input of the OR element 9 if there is no signal in the remote control channel 14. In this case, the trigger 10 generates an output signal equal in duration to the interval between two consecutive signals for the processing of programs from decoders 6. Claim 1.
