Toroidal coil-winding machine

Claim 2

A toroidal coil winding machine including a base, motor means positioned on the base, a magazine adapted to be loaded with wire and rotated by said motor means, a clamp adapted to hold a core for winding, an index table upon which said clamp is mounted and which is rotatably mounted relative to said base; a worm wheel fixed to said index table; a stepping motor operatively connected to a worm mounted on a shaft rotatably held in a bracket pivotally mounted on said base and rotatably mounting said worm gear shaft, said worm meshing with said worm wheel; and a universal joint operatively connecting said worm shaft and the shaft of said stepping motor.

Claim 3

A toroidal coil winding machine as in claim 1 wherein said bracket is removably fixed to said base by a fixing means, said bracket is mounted to move about an axis, and said bracket may be shifted about its axis by an eccentric mechanism.

Claim 4

A toroidal coil winding machine including a base, motor means positioned on the base, a magazine adapted to be loaded with wire and rotated by said motor means, a rotatable clamp adapted to hold a core for winding, in combination: an index table upon which said clamp is mounted and which is rotatably mounted relative to said base, a gear connected with said index table; a stepping motor operatively connected to a gear system and said gear system being operatively connected to said index table; said gear system including a worm gear mounted on a shaft, pivotable bracket means to rotatably support said worm gear shaft, and a universal joint operatively connecting said worm gear shaft and the shaft of said stepping motor, said worm gear meshing with said gear connected with said index table; a numerical control and tape reader system connected to said stepping motor to provide control signals to said motor; and a pick-up system connected to said control system and positioned on said base to monitor the wire being wound and to provide control signals to said control system.

Claim 5

A toroidal coil winding machine including a base, motor means positioned on the base, a magazine adapted to be loaded with wire and rotated by said motor means, a rotatable clamp adapted to hold a core for winding, in combination: an index table upon which said clamp is mounted and which is rotatably mounted relative to said base, a gear connected with said index table; a stepping motor operatively connected to a gear system and said gear system being operatively connected to said index table; said gear system including a worm gear mounted on a shaft, pivotable bracket means to rotatably support said worm gear shaft, and a universal joint operatively connecting said worm gear shaft and the shaft of said stepping motor, said worm gear meshing with said gear connected with said index table; a numerical control and tape reader system connected to said stepping motor to provide control signals to said motor; and a pick-up system connected to said control system and positioned on said base to monitor the wire being wound and to provide control signals to said control system.

Claim 6

A toroidal coil winding machine as in claim 3 wherein said control system includes a tape reader, a storage buffer, and an indexer unit which produces pulses to said stepping motor on a plurality of lines.

Claim 7

A toroidal coil winding machine as in claim 3 and also including an automatic wire cutter mounted on said base, said wire cutter comprising motor means, a rotatable cutter connected to said motor means and a fixed cutter member secured to said base.

Claim 8

A toroidal coil machine as in claim 3 and further including pivot means to mount said bracket to said base so that said bracket is pivotable about an axis, and an eccentric mechanism operable between said bracket and said base to selectively pivot said bracket.

Claim 9

A toroidal coil machine as in claim 1 and further including pivot means to mount said bracket to said base so that said bracket is pivotable about an axis, and an eccentric mechanism operable between said bracket and said base to selectively pivot said bracket.

Claim 10

A toroidal coil winding machine as in claim 3 wherein the pivot center of said pivotablE bracket and the pivotable center of said universal joint are vertically aligned.

Claim 11

A toroidal coil winding machine as in claim 1 wherein a plurality of idler rollers support and rotate said magazine and the machine further includes a magazine drive gear meshing with said idler rollers, a handle fixed to the shaft of said magazine driver gear, connection motor means to selectively rotate said magazine drive gear; a rotatable gear ring, a plurality of idler gear ring rollers meshing with and adapted to rotate said gear ring, a gear ring drive gear meshing with and driving said idler gear ring rollers, and a second handle fixed to the shaft of said gear ring drive gear, wherein the shafts of said magazine drive gear and said gear ring drive gear lie along a common axis and those shafts are not operatively connected.
