The recognition unit is a matrix embedded in the tray 11 across its entire width and consisting of two photosensitive layers, for example photoresistive. The first layer 12 along the part, which is a recognition layer, has a length equal to the length of the largest part. The second layer 13, which is the reading layer, has a length that is determined by the minimum value of the electrical signal that allows input of information from the recognition unit 1 to the comparison unit 2. The recognition unit includes a luminous flux source 14 and a part 15 moving along a chute 11. The device operates as follows. At the training stage, each part is installed so that it overlaps the matrix layer 13, and itself is located under layer 12. When the layer 13 overlaps, a signal is generated that permits the introduction of analogs (information from the photosensitive layer 12 of the recognition unit 1 to the comparison unit 2. the comparison unit 2 inputs analog information corresponding to the overlap area of the light part 15, the flow from source 14 to the photosensitive layer 12. From the control panel 6, the position of the switching unit corresponding to the data details, and simultaneously the pulse generator 9 is turned on. The pulses are counted by the binary counter 10, and the binary code of the memory block 4 is fed to the converter code 5. The analog signal corresponding to the code from the output of the code converter is analog 5 supplied to the second input Comparison Unit 2. In Comparison Unit 2, the given analogue from the recognition unit 1 is compared with the constantly increasing analogue from the code analog converter 5. If the specified analog signals from the Comparison Unit 2 match, aets signal disables pulse generator 9 and the memory unit 4 remains recorded code corresponding analogue signal for this part. Then, each of the p-parts is trained in a similar way, and in the memory block, n codes are written sequentially, each of which corresponds to a particular part. In the operating mode (recognition mode), the part is recognized by block 1, the analog information from which is fed to block 2 comparison. From the control panel b, the operation mode of switching unit 3 is established, in which the codes from block 4 of each part's memory are sequentially switched and, therefore, from the code equivalent converter 5, analog signals corresponding to each part are output to the comparing unit 2. Simultaneously, from the control panel b, an enabling signal is supplied to the input of the electromagnet power supply unit 7. With the coincidence of the signals from block 1 and the converter code-analogue 5 in the block. a resolution signal is supplied from its output to the third input of block 7, and the channel switched together with the code of each part and the corresponding part, at which the signals in block 2 coincided, is turned on by power supply 7 electromagnets of the corresponding electromagnet block 8 electromagnets. The part passes through the tray and is oriented in the working area of the included electromagnet. The proposed device allows to significantly simplify the recognition unit and instead of a rather complicated recognition device, for example in the form of a scanner connected to an adder, use the recognition unit in the form of two photosensitive layers; increase recognition speed.
