Then, after the wire 1 is clamped by the fixed clip device 21, the lifting clip device 22 is opened and raised to return to the initial position.

The lifting / lowering clip device 22 includes a wire guide 24.
The wire 1 penetrates through the wire guide 24 as shown in FIG. The distal end of the wire guide 24 is inserted into the guide guide plate 222, and when the wire guide 24 moves up and down as the lifting and lowering clip device 22 moves up and down,
The tip of the wire guide 24 advances and retreats in the guide guide plate 222. One lifting amount of the lifting clip device 22, ie,
The supply amount of the wire 1 at one time is indicated by SL in FIG.

And a nozzle 32. The nozzle 32 is moved by the XYZ moving device 6 around the tying terminal 51a as shown in FIG.
1 and the wire rod is wound around the terminal 51a. Note that the orbital motion in this specification does not need to be a motion along a circular locus, and the nozzle 3
2 may be a movement of winding around a wire around the lashing terminal 51a. A support member 7 is rotatably provided on the nozzle 32, and the support member 7 is rotated around the nozzle 32 by a driving device 8 provided in the main body 31. As shown in FIG. 3, the support member 7 rotates around the axis AX of the nozzle 32 in synchronization with the orbital movement of the nozzle 32 around the connecting terminal.

The bobbin 51 has two connecting terminals 51a and 51c. I have. FIG. 4A shows an initial position state in which the distal end of the wire drawn out of the nozzle 32 is clamped by the wire end clamping device 4 and the nozzle 32 is positioned near the terminal 51a. Is directed obliquely to the upper left. The revolving motion of the nozzle 32 starts from this initial position, and the rotation of the support member 7 also starts.

FIG. 4B shows the state when the nozzle 32 revolves 90 degrees counterclockwise from the initial position in the counterclockwise direction.
4 shows the state when the nozzle 32 revolves 180 degrees, and FIG. 4D shows the state when the nozzle 32 revolves 270 degrees. As the nozzle 32 revolves from FIG. 4 (a) to FIG. 4 (d), the wire 1
1a. At this time, the wire 1 is pulled out from the tip of the nozzle 32 by the revolving motion of the nozzle 32, but the wire 1 is bent and drawn out from the outlet of the nozzle 32 as shown in FIG. Relatively large tension is generated. For this reason, the hair terminal 51a includes:
A lateral load acts in a direction corresponding to the wire winding position, and a bending load acts on the tie terminal 51a in the nozzle tangential direction.

The support member 7 rotates from the initial position in FIG. 4A in conjunction with the revolution of the nozzle 32, rotates 90 degrees from the initial position in FIG. 4B, and also rotates 180 degrees in FIG. 4C. It rotates on its own, and in FIG. 4D, it also rotates by 270 degrees.

Although it is provided rotatably by extrapolating to the nozzle 2, it may be rotatably provided on the nozzle fixing plate 301 without being provided on the nozzle 32 as long as it rotates about the axis of the nozzle 32. further,
Although the support member 7 or 309 is described as projecting radially laterally of the nozzle 32, the lateral load acting on the lashing terminal 51a can be reduced by changing the rotation angle position in conjunction with the revolution movement of the nozzle 32. Any shape may be used as long as it supports it. Therefore, a support member directly supported by the nozzle fixing plate 301 may be used.
