This device works as follows.

The part is placed in the sensor, in this case the voltage is induced in the sensor, the signal from the sensor goes to the pulse shaper, which generates a pulse arriving at the parts counting unit. The parts counting unit counts the number of pulses corresponding to the number of parts, this information is fed to the indicator. The device allows to determine the number of parts passing through the sensor by counting the number of sensor pulses, but does not automatically recognize the type of part, since it does not compare the value of the output signal increment of the sensor corresponding to the part being recognized with the output increments corresponding to; by them, the details of all recognizable types lj.

However, the metering performance of this device is low, since the type of part is determined by

either by label or by some additional device, which leads to an increase in the cost of accounting -. In addition, counting the number

However, to automatically determine the types of parts with large

The number of types (nomenclatures) cannot be applied to this device, since it cannot store information about the threshold values of the recognition parameter (in this case, hardness) of the entire set of parts, for example, arriving at an automated warehouse. The device also cannot count these details.

by type, as it does not include the corresponding blocks. Thus, this device has a very narrow functionality.

The known device counts the number of similar parts in the container and does not provide for their identification and the corresponding calculation of the parts according to types h.

The disadvantage of the device is also narrow functionality.

The purpose of the invention is to expand the functionality of the device by identifying the parts to be counted.

The goal is achieved by the fact that in a device for counting parts, containing a sensor whose output is connected to the input of an analog-digital converter, a comparison unit, the output of which is connected to the first input of the memory unit, the first output of which is connected to the first input of the display unit, and input information, the output of which is connected to the second input of the memory unit, the counting unit and the unit for measuring the increments of the signal, the output of which is connected to the first input of the comparison unit and to the third input of the memory unit, the first output of which through a counting module connected to a second input of the display unit, the second output of the block memory is connected to the second input of the comparing unit, the output of analog-to- digital converter connected to the input signal measuring unit increments.

In addition, the signal increment measurement unit contains a register, a reference element, a subtraction element and a device switching pulse generator, the input of the signal increment measurement unit are the combined first inputs of the subtraction element, the comparison element and

the register, the output of which is connected to the second inputs of the subtraction element and the comparison element, the output of which is connected to the second input of the register, to the third input of which is connected the output of the device enable pulse generator, the output of the signal increment measuring unit is the output of the calculator element.

The memory block contains a pulse generator, a counter, a register, OR elements, an RAM memory matrix, and an AND element whose first input is the first input of the memory block,

and the output is the first output of the memory block, the second input of which is the first inputs of the OR elements, the third input of the memory block is the first input of the RAM memory, the output of which is the second output of the memory block, the output of the pulse generator through the counter is connected to the second input of the first OR element, the output of which through the register is connected to the second inputs of the AND element and the RAM memory, to the third input of which the output of the second OR element is connected.

In addition, the counting unit contains AND elements, counters and a decoder whose input is the input of the counting unit, the decoder outputs are connected directly to the first inputs of the AND elements and through the counters to the second inputs of the corresponding AND elements whose outputs are the outputs of the counting unit.

Expansion of the functionality of the device is carried out by automatically recognizing the type of a wide class of parts, as well as counting different types of parts. Automatic recognition is performed by comparing the output signal increments generated by the recognizable part with the output signal increments generated by the parts of all types to be recognized. Output increment codes are stored in a memory block. The result of the comparison of these codes is the identification of the type of part for which the code of the output signal increment corresponds to the increment code of the sensor output signal generated by the recognized part. In this case, the increment of the sensor output signal generated by a K-type part means the difference between the value of the sensor output signal when a part of this type is inserted into it and the value of the sensor output signal without a part (initial output signal value). FIG. 1 shows a block diagram of the device; in fig. 2 is a block diagram of a signal increment measurement unit; in fig. 3 is a diagram of a memory block; in fig. 4 - the scheme of the calculating block is functional. The device comprises a sensor 1, an analog-to-digital converter 2, a signal increment measurement unit 3, a comparison unit 4, a memory unit 5, an information input unit 6, a counting unit 7 and a display unit 8. The block 3 for measuring the increments of the signal contains a register 9, a driver 10 for switching on the device, a comparison element 11 and a subtracting element. Memory block 5 contains the first element OR 13, the register 14, the RAM memory matrix 15, the second element OR 16, the generator of the 17 pulses, the counter 18, the element AND 19. The counting unit 7 contains the decoder 20, the counters 21 and the elements AND 2 Block 6, the information input is implemented on the switches that form the binary-decimal code of the digit being set at the output, the switch outputs are connected to the binary-decimal binary to binary directors. The display unit 8 comprises a part type indicator and a number number indicator. Each of the indicators is standard and consists of: From a decoder connected to an indicator lamp. At the same time, the input of the part type indicator receives the part type code from the first input of block 8, and the number of parts code arrives at the input of the number input indicator from the second input of block 8. Two types of sensors are used as sensor 1 in the device: inductance and capacitive. If an inductive sensor is used, its output signal is the voltage induced when metal parts are inserted into the sensor. In the case of using a capacitive sensor, the output signal is the change in the voltage of the electric pap generated in the sensor when the dielectric part is placed in it. The device operates in two stages as follows. The first stage is learning, which consists in the fact that the increment code of the output signal of sensor 1, generated when sequentially inserting details of all types of components to be recognized in sensor 1, is recorded in memory block 5 to fill the output signal increments. To do this, first measure the output value of the sensor 1 without the part. In this case, the signal corresponding to the output signal of sensor 1 without detail, from its output is fed to the input of analog-digital converter 2, and from its output in the form of a digital code is fed to the input of block 3 and further to the first (informational) input of register 9. when the device is turned on, the driver 10 generates a pulse at the output, which is fed to the input of the register 9 and allows the information generated at the first input to be written to the register 9. The code of the initial output signal is fed to the first input of the comparison element 11, The second input of which receives the code zero, since the control input signal did not arrive at the read input (third input) of register 9. neither the information on the output of register 9 is generated. These codes are not equal, because the code value of the output signal of sensor 1 is not zero. Therefore, the comparison element 11 generates at the output a control signal Not equal, which is fed to the second input (readout) of the register 9, while the output value code is generated at its output, which is fed to the second input of the comparison element 11. A detail of the first type is inserted into the sensor. The value of the sensor output is changed. The input of block 3 receives the code of the new value of the output signal. This code goes to the first (informational) input of register 9, but information is not recorded in register 9, since the pulse shaper 10 does not generate a signal (no new device has been turned on). At the same time, the code of the new output signal is fed to the first input of the comparison element 11, at the second input of which the code of the initial output value is set. Signal. Comparison element 11 compares these codes and generates a new read signal at the output, according to which the code of the initial output signal comes from the output of register 9 to the input of the subtracted (second input) subtraction element 12, to the input of which is decremented the code of the new output signal caused introduced into the sensor part. The code sowing the difference of these values, i.e. the output incrementing code is fed to the third input of block 5 and is written into it as follows. Simultaneously with the introduction of the part into the sensor 1, the part type code located in the sensor is entered from the information input unit 6. This code goes to the second input of block 5 and then through the first element OR 13 to the input of register 14 and is written to it. The output signal increment code from the second output of block 5 passes on the in matrix of the RAM 15. At the same time, the part type code from the register 14 output goes to the second (address) input of the matrix 15, the record input (the third input) of which receives a signal from the output of the second element OR 16. The signal at the output of the second element OR 16 is formed as follows . Simultaneously with the arrival of the part type code at the input of the register 14, this multi-bit code is received at the input of the second element OR 16, and since the input of the element OR 16 is a multi-digit code representing an alternation of zeros and ones, then the output of the logical element OR 16 a signal is generated corresponding to one. Thus, the second element OR 16 converts the part type code into a control signal 78. According to this signal, the code formed at the first input of the matrix 15 and corresponding to the increment of the output signal of the sensor 1, called by a part of this type, is written to the matrix 15 at the address generated at its first input and the corresponding type of part located in the sensor. After that, a detail of the following type is entered into the sensor, etc. The second stage is the recognition that the increment code of the output signal of sensor 1, formed by a part of unknown type, is sequentially compared with the codes of increments formed by a known set of parts and stored by unit 5. The contactless sensor 1 is inserted a part of unknown type. Signal corresponding to the new value of the output signal of sensor 1, is converted into a digital code by analog-to-digital converter 2 and is fed to the input of block 3, which generates an increment code of the output signal as described above. From the output of block 3, the output signal increment code is fed to the first input of block 4 of the comparison. At the same time, the output signal increment codes stored by the block 5 are sequentially generated at the second input of block 4, as follows. The pulse generator 17 generates pulses that arrive at the input of the counter 18. The counter 18 sequentially generates read addresses coming from the output of the counter 18 to the second input of the element OR 13, and its output to the input of the register 14 and further to the second (address) input of the matrix 15, causes sequential reading of information stored by it. The read information comes from the second output of block 5 to the first input of block 4, where it is compared with the code received at the first input of block 4. In case of equality of the compared codes, comparison block 4 generates a control signal that goes to the first input of block 5 and further to the first the input element And 19, allowing the passage of information from the second input of this element iia its output and then to the first output of block 5. At the same time, the second input of the element And 19 enters

The code of the type of the part from the output of the register 14. Thus, the first output of the block 5 is the output of the type of the part, the type recognized by the device, and the element 19 acts as a valve that passes information about the type of part to the first output of the block 5 only when this type corresponds to the type of part placed in the sensor. The type code details from the first output of block 5 is fed to the second input of block 8 and the input of the counting unit 7 and then to the input of the decoder 20, which generates a signal at the output corresponding to the type of part, t, e. output K, where K - type details. The value of the code generated by the counter of the K-th part connected to the K-th output of the decoder 20 is increased by one and through the element 22 arrives at the output of the block 7 and further to the first input of the block 8. At the same time the first input of the element 22 is connected to the output of the counter 21, and on its second input receives a signal from the K-th output of the decoder 20.

The proposed device provides an increase in productivity by automatically recognizing the type of part, which makes it possible to automatically calculate different types of parts.
