Coil assembling apparatus, coil assembling method and manufacturing apparatus of electrical rotating machine

A coil assembling method comprising the steps of:

• preparing a segment arrangement body provided with a plurality of segment hold portions annularly arranged along a circumferential direction of said segment arrangement body, into which a plurality of coil segments can be respectively inserted from an outer radial directions of said segment arrangement body, each of said plurality of coil segments consisting of a pair of slot insertion portions extending substantially in parallel with each other and a linking portion for coupling said pair of slot insertion portions;
• guiding to insert one slot insertion portion of said pair of slot insertion portions of each of said coil segments into one of said segment hold portions each time said segment arrangement body rotates by a first predetermined angle;
• and
• guiding to insert the other one slot insertion portion of said pair of slot insertion portions into the other one of said segment hold portions when said segment arrangement body rotates by a second predetermined angle from the insertion of the one slot insertion portion.

A manufacturing apparatus of an electrical rotating machines including a coil assembling apparatus,

• said coil assembling apparatus comprising:
• a transport means for transporting in sequence a plurality of coil segments, each of said plurality of coil segments consisting of a pair of slot insertion portions extending substantially in parallel with each other and a linking portion for coupling said pair of slot insertion portions;
• a segment arrangement body capable of rotating around a center axis thereof and provided with a plurality of segment hold portions annularly arranged along a circumferential direction of said segment arrangement body, into which said plurality of coil segments transported by said transport means can be respectively inserted from an outer radial directions of said segment arrangement body;
• and
• a guide means for guiding to insert one slot insertion portion of said pair of slot insertion portions of each of said coil segments into one of said segment hold portions each time said segment arrangement body rotates by a first predetermined angle, and for guiding to insert the other one slot insertion portion of said pair of slot insertion portions into the other one of said segment hold portions when said segment arrangement body rotates by a second predetermined angle from the insertion of the one slot insertion portion.

A manufacturing apparatus of an electrical rotating machines including a wire rod providing section for supplying a linear wire rod, a first bending section for bending said linear wire rod supplied from said wire rod providing section, in a plane to form a predetermined shape consisting of a pair of slot insertion portions extending substantially in parallel with each other and a linking portion for coupling said pair of slot insertion portions, a second bending section for bending the wire rod bent in said first bending section, in a plane perpendicular to said plane, and a coil assembling apparatus for assembling coil segments bent in said second bending section, in line with slots of the electrical rotating machine,

• said coil assembling apparatus comprising:
• a transport means for transporting in sequence a plurality of coil segments, each of said plurality of coil segments consisting of a pair of slot insertion portions extending substantially in parallel with each other and a linking portion for coupling said pair of slot insertion portions;
• a segment arrangement body capable of rotating around a center axis thereof and provided with a plurality of segment hold portions annularly arranged along a circumferential direction of said segment arrangement body, into which said plurality of coil segments transported by said transport means can be respectively inserted from an outer radial directions of said segment arrangement body;
• and
• a guide means for guiding to insert one slot insertion portion of said pair of slot insertion portions of each of said coil segments into one of said segment hold portions each time said segment arrangement body rotates by a first predetermined angle, and for guiding to insert the other one slot insertion portion of said pair of slot insertion portions into the other one of said segment hold portions when said segment arrangement body rotates by a second predetermined angle from the insertion of the one slot insertion portion.
