Abstract

For winding a coil, the coil body is placed on winding mandrel 4 and winding wire 3 is fixed to the coil. The operator of the machine actuates a start button, causing a start signal to be applied to start-stop circuit 26 through line 31 and winding motor 5 to be started through line 27.

Automatic Coil Winding

For winding a coil, the coil body is placed on winding mandrel 4 and winding wire 3 is fixed to the coil. The operator of the machine actuates a start button, causing a start signal to be applied to start-stop circuit 26 through line 31 and winding motor 5 to be started through line 27.

Slotted disk 12, fixed to the shaft of motor 5 has, for example, 100 slots transmitting through photoelectric scanner 13, counting pulses which are applied to the advance counter 15 through line 14. Counter 15 is preset by advance program unit 17 so that, at predetermined counter values, control pulses are applied to step motor control 21 through line 19. These counting pulses, through line 34, are fed to the step motor 11 which, upon the arrival of each counting pulse, performs one step, thus causing a corresponding advance step to be effected by wire guide slide 8 through a threaded spindle. The frequency of the advance steps of guide 8 is, therefore, determined by the number of revolutions of mandrel 4, the spacing of the slots on disk 12, and the values in counter 15 set by program card 17A in unit 17.

Every hundredth electric pulse emitted by scanner 13 is transmitted from counter 15 to turn counter 16, incrementing the latter. Reversal program unit 18 is preset to the number of turns required per layer. When counter 16 indicates that a desired number of turns of a layer is reached, a reversing signal is transmitted through line 20 to reversing unit 22...
