Abstract
Abstract An apparatus for drawing wound coils into the grooves of stators or the like. A stator support member is provided for holding the stator, positioning the same onto the circle of guide fingers and, after the wound coils have been inserted into the grooves of the stator, removing the stator and removing it laterally away from the circle of guide fingers to a withdrawn position at which the stator is arranged with its axis vertical and then released onto a conveyer, mandrel or the like. An alignment member is also mounted for movement between a withdrawn position away from the circle of guide fingers and an operative position on the axis of the guide fingers and movable between them to precisely position them as the wound coils are being drawn into the stator grooves.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
164 words
An apparatus for drawing wound coils onto stators comprising: a frame, a plurality of parallel guide fingers extending from the frame and arranged in a circle and adapted to have hung on certain of said guide fingers wound coils to be inserted into grooves of a stator, means for positioning a stator concentrically relative to said circle of guide fingers, a stripper means movable axially in said circle, relative to at least some of said guide fingers for urging said hung wound coils into grooves of the stator, said means for positioning the stator comprising a stator support means for holding the stator while in an operative position on the guide fingers for receiving wound coils and also for holding the stator while in a withdrawn position in which the stator is positioned laterally of said axis away from said circle formed by the guide fingers, and said stator support means being movable between said operative and said withdrawn positions while holding the stator.
Claim 2
Independent Claim
164 words
An apparatus for drawing wound coils onto stators comprising: a frame, a plurality of parallel guide fingers extending from the frame and arranged in a circle and adapted to have hung on certain of said guide fingers wound coils to be inserted into grooves of a stator, means for positioning a stator concentrically relative to said circle of guide fingers, a stripper means movable axially in said circle, relative to at least some of said guide fingers for urging said hung wound coils into grooves of the stator, said means for positioning the stator comprising a stator support means for holding the stator while in an operative position on the guide fingers for receiving wound coils and also for holding the stator while in a withdrawn position in which the stator is positioned laterally of said axis away from said circle formed by the guide fingers, and said stator support means being movable between said operative and said withdrawn positions while holding the stator.
Claim 3
Dependent Claim
56 words
An apparatus according to claim 1, said stator support means being movable about a second axis spaced from and generally parallel to the axis of the said circle for movement of the stator between said operative and withdrawn positions and also along said second axis for moving the stator onto and off of said guide fingers.
Claim 4
Dependent Claim
65 words
An apparatus according to claim 2, in which the means for holding the stator comprises a mounting ring engagable with one axial side of the stator, rod means extending axially from the mounting ring, and locking plates associated with said rod means engaging the other axial side of the stator, and means for selectively engaging and disengaging said locking plates with said other stator side.
Claim 5
Dependent Claim
43 words
An apparatus according to claim 3, wherein the locking plates are fixed on the rod means, and including power means on the mounting ring for turning the rod means such that the locking plates engage or disengage the other side of the stator.
Claim 6
Dependent Claim
60 words
An apparatus according to claim 4, wherein said rod means comprises at least two rods fixed to respective switch forks in the mounting ring, a shift ring coaxial with the mounting ring, and engaging said switch forks, said power means arranged to turn the switch ring which in turn turns the switch forks and hence also the said rod means.
Claim 7
Dependent Claim
79 words
An apparatus according to claim 2, said stator support means comprising a shaft movaBle along said second axis, an arm connected to said shaft for movement therewith and extending radially from said shaft, a bifurcated frame at the other end of said arm, a mounting ring mounted between the two parts of said bifurcated frame for turning movement about a turning axis passing through said two parts, and said mounting ring including the said means for holding the stator.
Claim 8
Dependent Claim
83 words
An apparatus according to claim 6, said turning axis being located on said bifurcated frame such that it is substantially horizontal when the said arm has turned about said second axis to place the stator support means in said withdrawn position, such that the wound stator can be placed in a horizontal position with its central axis vertical by appropriate turning of the mounting ring about said turning axis regardless of the angle of inclination of the said second axis from the horizontal.
Claim 9
Dependent Claim
97 words
An apparatus according to claim 7, wherein said mounting ring engages one axial side of the stator and including rod means extending axially from the mounting ring, and locking plates associated with said rod means engaging the other axial side of the stator, and means for selectively engaging and disengaging said locking plates with said other stator side, and wherein the locking plates are releaseable at said withdrawn position such that the stator positioned with its axis vertical and the coil in the grooves thereof is dropped vertically downward onto a receiving means for further processing thereof.
Claim 10
Dependent Claim
35 words
An apparatus according to claim 1, including a guide finger alignment member movable along the said circle axis for precisely positioning the guide fingers during the drawing-in of the wound coils into the stator grooves.
Claim 11
Dependent Claim
58 words
An apparatus according to claim 9, including an alignmemt member support means supporting said alignment member and movable between an operative position in which the alignment member is on said circle axis and a withdrawn position in which the said alignment member is spaced laterally from said axis, away from the said circle formed by said guide fingers.
Claim 12
Dependent Claim
145 words
An apparatus according to claim 1, said stator support means being movable about a second axis spaced from and generally parallel to the axis of said circle for movement of the stator between the said operative and withdrawn positions and also along the said second axis for moving the stator onto and off of said guide fingers, a guide finger alignment member movable along the said circle axis for precisely positioning the guide fingers during the drawing-in of the wound coils into the stator grooves, an alignment member support means supporting said alignment member and movable about a third axis for moving the alignment member between an operative position in which the alignment member is on said circle axis and a withdrawn position in which the alignment member is spaced laterally from said circle axis, away from the said circle formed by the guide fingers.
Claim 13
Dependent Claim
39 words
An apparatus according to claim 11, including means on said stripper means for engaging the alignment member and moving it axially out of the circular space between the guide fingers as the stripper means moves axially through the stator.
