The winding machine electronic counter described in the example has the function of addition, subtraction automated counting, it can be used for transformers, motors, manufacturers restructuring the use of a variety of common winding machine. The working principle. The winding machine electronic counter is composed of photoelectric sensor circuit, shaping circuit, plus / minus four-digit identification circuit and counter circuit, it is shown in the figure 8-84. Photoelectric sensor circuit consists of resistors Rl, R2, R8, R9, and, and optocouplers VLCl, VLC2. RI, R8 and VLC1 form an addition counting sensor circuit. R2, R9 and VLC2 sensor form a subtraction count circuit. Shaping circuit consists of the Dl-D4 inside the six non-gate Schmitt trigger circuit ICl. Plus / minus identification circuit is composed of the A1,A2 inside the double-D flip-flop IC2. Four digits counter is composed of the resistors R3-R7, reset button S, counter / decoder IC lC3-1C6 and LED digital display A-D.
