Next, the processor drives the chuck device 32, advances the chuck arm 38, and closes the grip 38a, thereby holding six predetermined positions of the interphase paper unit 18 by the six chuck arms 38. The processor then opens the lid 34 and lowers the cradle 33.

  Subsequently, under control of the processor, the setting device 13 lowers the insertion head 41 located above the chuck device 32 to place the interphase paper unit 18 opposite to the insertion head 41. Next, as shown in FIG. 2, the chuck arm 38 is rotated and moved to be deformed into a predetermined shape corresponding to the positional relationship between the six claws of the insertion head 41.

  At this time, as shown in FIGS. 2 to 5, by rotating and moving six places in the vicinity of the joint portion of the interphase paper unit 18, the thickness direction of the connecting member 28 is orthogonal to the predetermined central axis. Then, the orientation is changed, and the shape of the interphase paper unit 18 is corrected so that the width direction of the connection member 28 is along the depth direction of the slot 22, that is, the radial direction.

  After correcting the interphase paper unit 18, the processor moves the chuck arms 38 in the radial direction, and inserts the respective connecting members 28 into the slits 65 b between the claws 65 a of the guide claws 65. At this time, the insertion head 41 is in the standby state, the guide arm 58 is in the open state, and the gate arm 73 b is in the standby position at the retracted position where the slit 65 b of the guide claw 65 is opened. Further, the pressing piece 70 and the guide claw 65 are retracted radially inward.

  After the connecting member 28 is inserted into the slit 65b, the processor drives the second air cylinder 74 to rotate the gate plate 73 to move the gate piece 73c to the restricting position and close the guide arm 58. That is, the guide claws 65 and the gate piece 73c hold the vicinity of the joint portion at both ends of the connecting member 28, and the guide arm 58 guides the central portion of the connecting member 28. Thus, the setting process is completed.

  In the mounting process, first, the processor drives the tension device to adjust the distance between the holder units 60 at both ends separated in the first direction, thereby pulling the connecting member 28 to apply tension. Subsequently, the insertion head 41 is moved in the first direction, inserted into the opening of the stator 17 and further lowered, so that the insertion head 41 is disposed opposite to a predetermined position on the inner circumferential surface of the stator 17. At this time, the guide arms 58a and 58b are disposed opposite to the target slot 22, and the gate pieces 73c and the guide claws 65 are both axial ends of the stator 17 slightly from the axial end of the target slot 22. It is arranged opposite to the outside position. Further, the pair of interphase insulating papers 26 and 27 of the interphase paper unit 18 are located on the outside of both axial ends of the stator 17 and the connecting member 28 is disposed opposite to the corresponding slot 22.

  Subsequently, the gate plate 73 is pivoted to retract the gate piece 73c, and the first rotary actuator 61 for claws is driven, whereby the vicinity of the joint portion of the connecting member 28 with the guide claws 65 is radially outward. Push out. Since the pair of guide arms 28a and 28b are slightly opened even in the closed state, the connecting member 28 is moved from the guide arms 28a and 28b with the radial outward movement of the guide claws 65 at both ends in the first direction. After being pulled out and moved radially outward, the connecting member 28 is inserted into the slot 22.

  Furthermore, by driving the second rotary actuator 66 for pressing, the pressing piece 70 is pushed outward, and the interphase insulating papers 26 and 27 are pressed outward toward the stator 17. Subsequently, while maintaining the pressed state by the pressing piece 70, the first rotary actuator 61 for claws is driven to retract the guide claws 65 in the inner circumferential direction. When the guide claw 65 retracts, as shown in FIG. 3 and FIG. 4, the connecting member 28 returns to a posture in which the original width direction intersects with the insertion direction in the slot 22, so it is easily held stably.

  After the guide claw 65 retracts, the processor drives the second rotary actuator 66 at a predetermined timing to retract the pressing piece 70. Furthermore, the processor raises the insertion head 41 and moves it in the first direction to retract it out of the stator 17. As described above, the connecting member 28 is inserted into the predetermined slot 22, and one interphase paper unit 18 is mounted.

  Subsequently, by rotating the stator 17 by a predetermined angle, the slot 22 to which the interphase paper unit 18 is to be mounted next is moved to the target position. The above steps are repeated a plurality of times, and a plurality of interphase paper units 18 are sequentially attached. In the present embodiment, by rotating 90 degrees and sequentially mounting four interphase paper units 18, the process of mounting interphase paper units 18 on the entire inner circumference of the coil 25 for one layer is completed.

  According to the interphase sheet loading device 1 and the interphase sheet loading method of the present embodiment, the phase interleaver unit 18 can be attached with high accuracy and speed, and production control can be made more efficient. That is, for example, it is difficult to insert the connecting member 28 into the slot 22 at the inlet 22a of the slot 22 of the stator 17. However, by restricting the direction of the connecting member 28, the guide claws 65 provided on the insertion head 41 The connecting member 28 can be moved in the radial direction while being held in a predetermined posture. For this reason, for example, even in the case of using a phase sheet having low rigidity and having warping and twisting, the sheet can be smoothly attached by maintaining the postures of the interphase insulating sheets 26 and 27 and the connecting member 28. For example, even if the width of the inlet 22a of the slot 22 is narrow and the gap is narrowed by the cuffs, the direction of the connecting member 28 can be corrected and held, and the insertion operation can be performed with high accuracy. It can be done quickly.

  Further, the connecting member 28 is held or released from the slit 65b by opening and closing the gate piece 73c, so that the delivery process of setting the connecting member 28 to the guide claw 65 and the radial direction of the guide claw 65 By the operation, the insertion process of inserting the connecting member 28 into the slot 22 can be smoothly performed.

  Further, after arranging the connecting member 28 in the slot 22, the connecting member 28 is in the slot 22 when retracting the guide claw 65 by retracting the guide claw 65 in a state of being pressed by the pressing piece 70. It can be prevented from coming off.
