Abstract:
1. A weaving machine for a coil assembly of a rotary electric machine by weaving a plurality of coil wire segments, each having a plurality of turn portions, the weaving machine comprising: a rotating and driving section including a stationary pulley coaxially fixed to a shaft column mounted on a base, a rotary member rotatably supported by the shaft column so as to be rotatable about a center axis of the shaft column, a plurality of rotary pulleys supported by the rotary member so as to be relatively rotatable, and drive-force transmitting members engaged between the rotary pulleys and the stationary pulley, the rotating and driving section being configured such that the rotary pulleys rotate on axes thereof while rotating about an axis of the stationary pulley keeping the same attitudes; a plurality of movable members located above the rotary pulleys and being movable in X- and Y-directions on a plane perpendicular to a rotating axis of the rotary member; a plurality of coil feed magazines including first transfer paths through which the coil wire segments are transferred, and placed in inclined state such that axes of the coil wire segments swingably supported by the movable member through pivots at one ends thereof and being transferred through the first transfer paths to the other end side cross on the rotating axis; an orbit specifying member for specifying an orbit of the coil feed magazines during rotation; a rotation synchronizing member for causing the coil feed magazines to rotate in synchronism with each other; and a coil transfer device that grips and transfers woven coil wire segments in a state where the turn portions of the coil wire segments cross one another.
