The radial actuator 112 is attached to the slider 108, and by moving the lifter 109 in the radial direction of the flange 26, the attachment / detachment tool 100 is moved in the radial direction. Although detailed illustration is omitted here, the contact / detachment actuator 113 is attached to the lifter 109, and the movable plate 101b is moved in the thickness direction by moving the movable holder 110b in the thickness direction of the flange 26. The pair of tip portions 102a and 102b are brought into contact with each other.

(Movement suppression mechanism 120)
As shown in FIGS. 3 to 6, the wire rod winding device 10 is a movement suppressing mechanism for suppressing the pull-out portion W ₂ from moving from the tip end portion 34 of the clip 30 toward the base end portion 32 of the clip 30. 120 is further provided. The movement restraining mechanism 120 is for driving the pin 122 (first pin) that can be inserted and removed from the through hole 28 provided in the flange 26 and the pin 122 so that the pin 122 is inserted and removed from the through hole 28. It has a pin drive unit 125 (first pin drive unit).

It has a pin support 126 that supports the pin 122 and an advancing / retreating actuator 127 for moving the pin 122 in the thickness direction of the flange 26 at substantially the same position.

As an example, the pin support 126 shares the base 78 with the pin support 76 and is radially inside the flange 26 of the pin support 76 slider 79 with respect to the base 78. It has a slider 129 that is reciprocally attached in the thickness direction of 26. The slider 129 can be reciprocated in the thickness direction of the flange 26 as described above by the advance / retreat actuator 127. The pin 122 is fixed to the slider 129. As described above, the pin drive unit 125 can move the pin 122 and the pin support 126 in the thickness direction of the flange 26 independently of the pins 72a and 72b and the pin support 76 by the advance / retreat actuator 127. ..

The pin support 126 further shares the arm 77 with the pin support 76. As a result, the pin drive unit 125 can move the pin 122 and the pin support 126 in the circumferential direction of the flange 26 integrally with the pins 72a and 72b and the pin support 76 by the angular displacement actuator 81. ..

(Position adjustment jig 130)
As will be described later, the attachment / detachment tool 100 is used for sandwiching the pull-out portion W ₂ and opening / closing the clip 30, and moves mainly outside the flange 26. Therefore, the slider 108 and the lifter 109 that form the attachment / detachment support 106 are arranged outside the flange 26. The slider 108 that supports the lifter 109 has an extension 108a that extends inward in the radial direction of the flange 26. The position adjusting jig 130 is connected to the expansion portion 108a.

The position adjusting jig 130 is arranged outside the flange 26 in the thickness direction so as to overlap the flange 26 when viewed from the thickness direction of the flange 26. When the slider 108 moves inward in the thickness direction, the surface of the position adjusting jig 130 on the flange 26 side comes into contact with the outer surface of the flange 26. As a result, the movement of the slider 108 and thus the attachment / detachment tool 100 in the thickness direction is restricted, and the position of the attachment / detachment tool 100 with respect to the reel 20 in the thickness direction is adjusted.

(Control device 140)

A control device 140 for controlling the drive unit 125 (in other words, the movement suppression mechanism 120) is further provided.

In addition to the configuration to be controlled, the control device 140 is connected to an encoder 142 for detecting the rotation position of the reel 20 and a clip position sensor 144 for detecting the rotation position of the clip 30. The clip position sensor 144 may be realized by, for example, an optical sensor. The clip position sensor 144 may detect, for example, the position of the clip 30 itself, or the rotation position of the configuration included in the reel 20 whose relative rotation position with respect to the clip 30 does not change may be grasped in advance. By detecting the rotational position of the configuration included in the reel 20, the rotational position of the clip 30 may be derived based on this detected value. The control device 140 can control the control target by executing a program stored in advance in the storage unit of the control device 140 based on the values detected by the encoder 142 and the clip position sensor 144.

In the thickness direction of the flange 26, the tips of the pins 72a, 72b, and 122 are in the retracted position, and the pin 122 is not inserted into the through hole 28 of the flange 26.

When the reel 20 is supported by the reel drive mechanism 50, the flange 26 comes into contact with the pull-out portion lifting mechanism 70 and the contact / release tool 100 and the proximal air chuck 51b. As a result, the clip 30, the pull-out portion lifting mechanism 70, and the attachment / detachment tool 100 are collectively arranged proximal to the rotating shaft 52b and distal to the rotating shaft 52a in the thickness direction of the flange 26.

After fixing the start end of the wire rod W to the winding cylinder 22 in step S1, the control device 140 controls the reel drive mechanism 50 and the wire rod feeding mechanism 60 to wind the wire rod W as shown in FIG. 8 (A). The wire rod winding process (wire rod winding step) to be wound around the body 22 is executed (step S2 in FIG. 7). In this step S2, the reel drive mechanism 50 rotationally drives the reel 20, and the wire rod feeding mechanism 60 feeds the wire rod W to the reel 20 while applying tension to the wire rod W. The wire rod feeding mechanism 60 reciprocates the traverse roller 62 in its axial direction (in other words, in the thickness direction of the flange 26). By appropriately combining these operations, the wire rod W is wound around the winding cylinder 22.

Further, when the control device 140 is executing step S2, the control device 140 determines whether or not the wire rod W is about to be fully wound with respect to the winding cylinder 22 based on the value detected by the encoder 142 (step S3 in FIG. 7).

When the control device 140 determines that it is not immediately before full winding (“NO” in step S3), the control device 140 returns to step S2 and continues the wire rod winding process in step S2.

On the other hand, when the control device 140 determines that the reel is about to be fully wound (“YES” in step S3), the control device 140 stops the rotation operation of the reel 20 (step S4 in FIG. 7) as shown in FIG. 8 (B).
