(Process S1) Core member conveyance process (Process S2) Posture deformation process (first half)
(Process S3) Posture deformation process (second half)
(Step S4) Chuck preparation (Step S5) Locking plate contact step (Step S6) Chuck step and winding step (Step S7) Winding completion step (Step S8) Steps S2 to S7 are repeated (Step S9) Step of carrying out the core member after the last core piece is deformed. Each step described above will be described in detail below.

(Process S1) Core member conveyance process First, as shown in FIG. 7, the core member 1 is thrown into the winding apparatus 100 from the throwing direction F in a state where the core member 1 is linearly arranged. And as shown to Fig.22 (a), the holding pins 56a and 56b at the time of injection | emission are the states which do not protrude in the core member 1 direction with respect to the 1st holding | maintenance part 5a and the 2nd holding | maintenance part 5b. Further, the holding pins 58a, 59a, 58b, and 59b are also in a state where they do not protrude in the direction of the core member 1 with respect to the first holding part 5a and the second holding part 5b. And holding pin 55a, 55b, 57a, 57b is the state which protrudes in the core member 1 direction with respect to the 1st holding | maintenance part 5a and the 2nd holding | maintenance part 5b.

  The core member 1 thrown into the winding device 100 has the first holding position of the opening 30 provided in the yoke portion 3 of the first core piece 2 located at the end in the making direction F. The holding pin 56a of the part 5a and the holding pin 56b of the second holding part 5b are moved to a position where they can be inserted. Then, as shown in FIGS. 8, 9, and 22B, the linear motion portion 562a and the linear motion portion 562b are driven to move the upper and lower plates 561a and 561b in the inner direction A, respectively. Then, the holding pin 56a and the holding pin 56b are inserted into the openings 30 on both end surfaces of the yoke part 3 of the core piece 2, respectively. Further, the linear motion portion 572a and the linear motion portion 572b are driven to move the upper and lower plates 571a and 571b in the outer direction B, respectively, and the holding pin 57a, the holding pin 57b, and the first holding portion 5a, It is set as the state which does not protrude in the core member 1 direction with respect to the 2nd holding | maintenance part 5b.

(Process S2) Posture deformation process (first half)
In the posture deformation step (first half), the second drive shaft 53 rotates the second rotation shaft 51 in the rotation direction J and the first holding unit 5a and the second holding unit 5b simultaneously rotate in the clockwise direction E. Rotate by half (θ / 2) of a predetermined angle. Then, as shown in FIGS. 10, 11, and 22C, the positions of the upper and lower plates 561a and 561b and the positions of the holding pins 56a and 56b are shifted in the stacking direction Y.

  Then, the linearly moving portion 562a and the linearly moving portion 562b are driven, and the upper and lower plates 561a and 561b are moved in the outer direction B with respect to the first holding portion 5a and the second holding portion 5b. It is set as the state which does not protrude in the member 1 direction. This is because when the second core piece 2 adjacent to the core piece 2 is moved to the loading position and the holding pins 58a and 58b are moved to the positions of the holding pins 56a and 56b, the upper and lower plates 561a and 561b. This is to prevent interference with.

  Further, the positions of the upper and lower plates 571a and 571b and the positions of the holding pins 57a and 57b are shifted in the stacking direction Y. Then, the linearly moving portion 572a and the linearly moving portion 572b are driven, and the upper and lower plates 571a and 571b are moved in the inner direction A with respect to the first holding portion 5a and the second holding portion 5b. Let it be the state which protrudes in the member 1 direction. This is to prevent interference with the upper and lower plates 571a and 571b when the holding pins 55a and 55b move to the positions of the holding pins 57a and 57b.

(Process S3) Posture deformation process (second half)
In the posture changing step (second half), the first holding portion 5a and the second holding portion 5b are simultaneously rotated in the clockwise direction E to a predetermined angle θ. Thereby, the attitude | position of the core member 1 arrange | positioned linearly deform | transforms, and the 1st core piece 2 moves to the winding position of the coil | winding 20. FIG. When the first core piece 2 moves to the winding position of the winding 20, the second core piece 2 moves to the position before the previous first core piece 2 moves.

  Further, as shown in FIGS. 12, 13, and 22D, the holding pins 55a and 55b are holding pins 57a and 57b, the holding pins 57a and 57b are holding pins 59a and 59b, and the holding pins 59a and 59b are holding pins. 58a and 58b, the holding pins 58a and 58b are moved to the holding pin 56a, and the holding pin 56a is moved to the holding pin 55a.

(Step S4) Chuck Preparation As shown in FIG. 14 and FIG. 22 (e), the chuck preparation is performed by driving the linear motion portion 562a and the linear motion portion 562b to move the upper and lower plates 561a and 561b inside. By moving in the direction A, the holding pin 58a and the holding pin 58b are inserted into the openings 30 on both end faces of the yoke part 3 of the second core piece 2, respectively. The subsequent steps S5 and S6 are also in the same state as the state of FIG.

And the 1st locking plate 61a and the 2nd locking plate 61b contact | abut to the yoke part back surface 3a of the core piece 21, respectively (from the state of FIG. 16, FIG. 24 to the state of FIG. 17, FIG. 25).

(Step S6) Fixing step and winding step When the first drive source portion 66 is further rotated, the holding mechanism portion 5 winds the winding 20 via the first guide portion 64a and the second guide portion 64b. The core piece 21 is pulled in the direction D opposite to the protruding direction C of the tooth portion 4. Then, when the holding mechanism portion 5 is pulled, the yoke portion back surface 3a of the core piece 2 around which the winding 20 held by the holding mechanism portion 5 is wound becomes the first locking plate 61a and the second locking plate 61b. It will be pressed and fixed.

  At this time, the fixing force when pressed can be adjusted from the load due to the rotational torque of the first rotating shaft 67 of the first drive source 66. Therefore, regardless of the shape of the yoke portion back surface 3a, it can be adjusted and fixed so as to have a preset constant force. Therefore, the core piece 2 can always be fixed at the same position. Next, the flyer 7 for winding supply winding is moved to the winding start position (FIG. 18). And the coil | winding 20 is wound by the flyer 7 to the teeth part 4 of the core piece 2 for winding the coil | winding 20 (FIG. 20). Note that the flyer 7 is attached to a winding head (not shown), supplies the winding 20 while turning around the tooth portion 4, and winds the winding 20 around the tooth portion 4.

(Step S7) Winding Completion Step The fryer 7 for winding supply winding is returned to its original position, and the rotation direction for driving the first rotating shaft 67 of the first drive source section 66 is opposite to that in steps S5 and S6. In the rotation direction H2 (FIG. 19). Then, the first locking plate 61a and the second locking plate 61b move in the opposite direction D and are separated from the yoke part back surface 3a of the core piece 2 (from the state of FIGS. 17 and 25 to FIG. The state of FIG.

(Step S8) Steps S2 to S7 are Repeated Steps The core piece 2 after winding 20 is wound by the posture changing step (first half) of step S2 and the posture changing step (second half) of step S3. Move to 20 winding positions. Next, Steps S <b> 3 to S <b> 7 are performed, and the winding 20 is wound around the second core piece 2. The third and subsequent core pieces 2 are similarly wound with the winding wire 20 by the method described above. By repeating steps S2 to S7 for the number of core pieces 2 constituting the core member 1 (here, 9 pieces), the windings 20 are wound around all the core pieces 2. FIG. 21 shows a state where the winding 20 is wound around all the core pieces 2.

(Step S9) Step of unloading the core member after deforming the posture of the last core piece After winding the windings 20 to all the core pieces 2, the posture of the core piece 2 is deformed, and the core member 1 is linear. The core member 1 is unloaded from the discharge direction G. Thereby, the winding process to the core member 1 is completed. After all the winding steps are completed, each core connecting portion 31 of the core member 1 is bent and arranged in an annular shape so that the teeth portion 4 of each core piece 2 is on the inside. And the stator 10 as shown in FIG. 6 is completed by fixing the yoke parts 3 of the core piece 2 of the both ends of the core member 1 by welding etc. (FIG. 6).

  According to the winding device and the winding method of the winding device configured as described above, the first holding unit and the second holding unit are simultaneously pulled by the same first drive source unit, and the holding mechanism Since the portion is pulled with respect to the fixing mechanism portion, the positional variation between the upper side and the lower side of the tooth portion hardly occurs, and the core piece can be pulled with high accuracy in the vertical direction. Therefore, the entire yoke portion rear surface of the core piece has the first engaging plate and the second engaging portion with both end sides in the stacking direction of the yoke portion having a large deformation force among the core pieces as working points (first holding portion and second holding portion). The winding of the winding around the tooth portion of the core piece can be performed while being pressed by the stop plate. For this reason, even if the teeth part of the core piece is tightened intensively by winding of the winding, the back surface of the yoke part of the core piece can suppress bowing deformation in the stacking direction. Therefore, since the bow shape of the core piece is suppressed, and the fixing position variation between the upper and lower sides of the core piece is suppressed, the winding can be wound while keeping both end surfaces in the stacking direction of the teeth portion in parallel. The winding alignment can be improved.

  Furthermore, since the pulling force can be adjusted by the load generated in the rotational torque of the first drive source unit, the pulling can be performed with a constant force regardless of the shape error of the tooth portion. Therefore, the core piece can be fixed with a constant force regardless of the shape of the back of the yoke portion of the tooth portion, and thus the winding alignment variation of each core piece can be further suppressed.

  In addition, by arranging the first holding part of the holding mechanism part and the second drive source part of the second holding part in the lower direction of the core piece and simultaneously driving them, a space in the upper direction of the core piece is secured. Can do. As a result, the drive range of the flyer can be expanded, so that the continuous winding from the core piece to the adjacent core piece can be performed with high accuracy. In addition, this can show the same effect even if it arrange | positions a 2nd drive source part to the upper direction of a core piece.

  Furthermore, since the first holding part and the second holding part of the holding mechanism part are driven by the same second drive source part, they are always at a fixed position with respect to the holding mechanism part. Can be secured.

  Furthermore, by dividing the locking plate that contacts the back of the yoke part of the core piece, even if the back part of the yoke part of the core piece is already bow-shaped, the bow shape is corrected and the winding is performed. Since it can be wound, the alignment of the windings can be improved.

  In addition, since the locking plate and the holding mechanism are moved using the cam mechanism, the position reproducibility of the locking plate and the holding mechanism is improved, and the continuous core pieces are wound without variation. It can be carried out.

  Furthermore, since the movement of the locking plate and the movement of the holding mechanism can be continuously performed by the same first drive source unit, the tact time can be shortened and the apparatus size can be reduced.
