Let As a result, the first and second leads R1 and R2 of each axial component P in the component tape 900 are sandwiched between the comb teeth 223a and 224a of the first and second feed members 223 and 224, respectively. Then, the operation of the second air cylinder 227 is stopped at the time when the sandwiching is completed.

Next, as shown in FIG. 11C, the first air cylinder 226 operates in the extending direction (Y-axis direction) to supply the component tape 900 together with the first and second feeding members 223 and 224 to the downstream side (Y-axis direction). ) Is moved by the disposition interval d of the axial parts P. Then, when the movement is completed, the operation of the first air cylinder 226 is stopped. Then, the first and second leads R1 and R2 of the axial component P are clamped by a clamp mechanism 261 described later.

Next, as shown in FIG. 11D, the second air cylinder 227 operates in the extending direction (Z-axis direction) to raise the first and second feed members 223 and 224 along with the first air cylinder 226 in the Z-axis direction. Let As a result, the first and second leads R1 and R2 of the axial component P of the component tape 900 are extracted from between the comb teeth 223a and 224a of the first and second feed members 223 and 224, respectively. Then, when the extraction is completed, the operation of the second air cylinder 227 is stopped.

As a result, the cut first and second leads R1 and R2 held by the first and second holding walls 243a and 243b are pushed down and bent by the first and second bending members 248 and 249.

Finally, as shown in FIG. 13D, the first and second leads R1 and R2 are sandwiched between the first and second bending members 248 and 249 and the first and second holding walls 243a and 243b. The axial part P is bent at a substantially right angle, and the axial part P is positioned at a part supply position protruding from the upper surface of the device body 250 of the cutting/bending device 240. Then, the air cylinder 265 operates in the contracting direction (Z-axis direction) to rotate the first and second clampers 263 and 264 in the clockwise direction of FIG. 12C about the rotation axis C, and the first and second clampers 263. , 264 the first and second covering portions 263a and 264a are separated from the upper portions of the first and second holding walls 243a and 243b.

The axial component P positioned at the component supply position is picked up by the grip claws of the component mounting head 38 of the component mounting device 30 and mounted at the component mounting position on the board B. The above operation is one cycle of the cutting/bending operation and the clamping operation of the component tape 900, and thereafter, the operation of one cycle is repeated for each one axial component P. On the other hand, as shown in FIG. 14, the first and second tapes T1 and T2 including the respective tip portions of the first and second leads R1 and R2 separated from the axial component P are discharged from the tip of the feeder main body 210.
