Abstract

Apparatus for precision level winding of coils. The apparatus is particularly adapted for precision level winding of a continuous set of coils, in which each of the coils in the set may have a number of turns differently from each of the other coils in the set and may be of a length and pitch different from each of the other coils in the set. The apparatus includes means for automatically applying coils of wire to a coil holder member which has a plurality of aligned substantially coaxial levels. The apparatus includes control means by which each of the variables involved is readily adjustable. There is relative axial movement between a rotary wire-laying flyer and the coil holder member. The apparatus includes means for applying a desired number of turns of wire to each level in a manner such that the spacing between turns is substantially constant, and the number turns applied to each level adjusted readily and easily.

In a coil winding system adapted to provide incremental axial movement during mutual rotation and relative axial movement of a wire-laying device and a coil holder member, apparatus for effecting and controlling the incremental axial movement comprising:

A. motive means responsive to an increment input pulse for effecting a predetermined relative axial movement between the wire-laying device and the coil holder;
B. reference pulse generating means adapted to issue a predetermined number of reference pulses with each revolution of mutual rotation between the wire-laying device and the coil holder;
C. radial position pulse generating means adapted to issue a radial position pulse at a predetermined radial position during each revolution of mutual rotation between the wire-laying device and the coil holder;
D. a first memory for storing a binary representation of the length of a predetermined section of the coil holder;
E. a second memory for storing a binary representation of the number of turns to be laid on said predetermined section of the coil holder;
F. a first presettable counter adapted to receive the binary representation from said first memory and to be selectively preset thereby, said first counter further including a count input;
G. first decoding means connected to sense the count in said first presettable counter and responsive to a predetermined count therein for issuing an output pulse;
H. bistable means having first and second stable states, said bistable means being connected to said first decoding means and responsive to an output pulse therefrom for assuming said second state;
I. first gating means having an output, a first input connected to receive said reference pulses and a second input coupled to said bistable means whereby said reference pulses appear at the output of said gating means only when said bistable means is in said first state;
J. a second presettable counter adapted to receive the binary representation from said second memory and to be selectively preset thereby, said second counter including a count input;
K. second decoding means connected to sense the count in said second presettable counter and responsive to a predetermined count therein for issuing an output pulse;
L. second gating means having an output, a first input connected to receive the binary representation from said second memory, and a second input coupled to receive the output pulse from said second decoding means whereby said binary representation from said second memory is preset into said second presettable counter after said second decoding means issues an output pulse;
M. means coupling the output from said first gating means to said count input of said first presettable counter;
N. means coupling the output from said first gating means to said count input of said second presettable counter;
and
O. means coupling the output of said second decoding means to said motive means whereby repetitive output pulses from said second decoding means serve as increment input pulses thereto.
