US 5,511,502 A · Automatic loader for a stator coil lacing machine

Abstract

An automatic loader for a stator coil lacing machine includes structure for advancing a stator from a first position adjacent an arbor of the machine to a second position away from the arbor. The automatic loader also includes structure for moving the arbor between a lowered position away from the stator whereby the advancing structure moves the stator between first and second positions, and a raised position so that the stator is positioned on the arbor. The automatic loader may further include structure for disengaging a lacing cord feeder tube reciprocating drive of the machine from a cam of the machine when the arbor is lowered so the reciprocating drive is drivingly reengaged with the cam when the arbor is raised. The automatic loader may also include structure for maintaining driving engagement between a lacing needle drive of the machine and a lacing cord feeder tube oscillating drive when the arbor is raised and lowered. The advancing structure may include a table on which the stator lies and structure for rotating the table so that the stator moves between first and second positions. The automatic loader may also include structure for uncoupling an indexing motor of the machine from an indexing ring of the machine when the rotating structure moves the stator between first and second positions. The present invention also includes a method of loading and unloading a stator respectively on and from a stator coil lacing machine.

Dependent claims

A stator coil lacing machine, comprising:

means for orienting a first stator on the machine so that stator coils of the first stator can be laced, the orienting means including an arbor on which the first stator is positioned to lie;
means for stitching lacing cord around the first stator coils;
lacing cord handling means for receiving a continuous length of lacing cord and delivering the lacing cord to the stitching means;
means for reciprocating the lacing cord handling means so that the lacing cord handling means moves generally parallel to the arbor;
means for oscillating the lacing cord handling means so that the lacing cord handling means rotates through an arc;
a table on which the first stator is positioned to lie;
means for rotating the table so that the first stator advances from a first position adjacent the arbor to a second position away from the arbor;
and
means for moving the arbor between a lowered position away from the first stator to allow the rotating means to move the first stator from the first position to the second position, and a raised position to allow a second stator on the table to be positioned to lie adjacent the arbor.
