(3. Feeder operation)
Next, the operation of the feeder 200 according to the above-described embodiment will be described. The operation of the feeder 200 includes a feeding operation of the component tape 900, a clamping operation of the first and second leads R1 and R2 of the axial component P, and a cutting / bending operation.

First, the feeding operation of the component tape 900 will be described with reference to FIGS. 11A to 11D. Here, as shown in FIG. 11A, the component tape 900 stored in the tape storage box 211 a loaded in the tape storage unit 211 is pulled out by the operator, and is supplied to the feeding device 220 via the feeding roller 214. It is set below the first and

second feeding members

223 and 224, and the feeding device 220 is moved and locked to a standby position on the downstream side (Y-axis direction) by the operator.

In this standby state, the

first comb teeth

223a and 224a adjacent to the

first comb teeth

223a and 224a of the first and

second feed members

223 and 224 are positioned at the positions of the first and second leads R1 and R2 of the first axial component P. The space is located.

Next, as shown in FIG. 11B, the first air cylinder 227 moves in the Z-axis direction together with the first air cylinder 226 by operating in the direction in which the second air cylinder 227 contracts (Z-axis direction). Let Accordingly, 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 feeding members

223 and 224, respectively. Then, the operation of the second air cylinder 227 is stopped when this clamping is completed.

Next, as shown in FIG. 11C, the first air cylinder 226 is operated in the extending direction (Y-axis direction) to supply the component tape 900 together with the first and

second feed members

223 and 224 on the downstream side (Y-axis direction). ) Is moved by the arrangement interval d of the axial parts P. Then, when this 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 first air cylinder 227 moves in the Z-axis direction together with the first air cylinder 226 by moving in the direction in which the second air cylinder 227 extends (Z-axis direction). Let As a result, the first and second leads R1 and R2 of the axial component P in the component tape 900 are extracted from between the

comb teeth

223a and 224a of the first and

second feeding members

223 and 224, respectively. Then, when the extraction is completed, the operation of the second air cylinder 227 is stopped.

Then, as shown in FIG. 11A, the first air cylinder 226 operates in the contracting direction (Y-axis direction), and only the first and

second feeding members

223 and 224 are directed toward the supply upstream side (Y-axis direction). Move to the standby position. Then, when this movement is completed, the operation of the first air cylinder 226 is stopped. The above operation is one cycle of the feeding operation of the component tape 900, and thereafter the operation of one cycle is repeated.

Next, the clamping operation and the cutting / bending operation of the first and second leads R1 and R2 of the axial component P will be described with reference to FIGS. 12A to 12C and FIGS. 13A to 13D. Here, as shown in FIG. 12A, the first and second leads R1 and R2 of the first axial component P of the component tape 900 fed by the feeding device 220 are the first and second leads of the component holding member 243. 2 Assume that the first and

second grooves

243c and 243d of the holding

walls

243a and 243b are fitted. At this time, although not shown, the first and

second feeding members

223 and 224 of the feeding device 220 are located at an initial position on the upstream side of the feeding that does not interfere with the cutting / bending mechanism 241 and the clamping mechanism 261.

In an appropriate state, the air cylinder 265 operates in the extending direction (Z-axis direction), and the first and

second clampers

263 and 264 are rotated counterclockwise in FIG. As described above, the first and

second cover portions

263a and 264a of the first and

second clampers

263 and 264 are brought into contact with the upper portions of the first and

second holding walls

243a and 243b. Then, when this contact is completed, the operation of the air cylinder 265 is stopped. Accordingly, the first and

second covering portions

263a and 264a cover the respective openings of the first and

second grooves

243c and 243d into which the first and second leads R1 and R2 are fitted. The axial part P can be prevented from falling off.

Next, as shown in FIGS. 12B and 13B, the inclined surface 252a of the cutting cam 252 contacts the roller 253e of the cutting cam follower 253 by operating in the direction in which the air cylinder 251 extends (Y-axis direction). When the roller 253e slides along the surface 252a, the cutting cam follower 253 is lowered along with the first and

second cutting blades

244 and 246 in the Z-axis direction. As a result, the first and second leads R1 and R2 held by the first and

second holding walls

243a and 243b are connected to the first and

second cutting blades

244 and 246 and the first and second

cutting blade receivers

245 and 247, respectively. And cut from the first and second tapes T1 and T2.

Next, as shown in FIG. 12C and FIG. 13C, the air cylinder 251 further operates in the direction (Y-axis direction) so that the inclined surface 254a of the bending cam 254 contacts the roller 255b of the bending cam follower 255, As the roller 255b slides along the inclined surface 254a, the base 255a of the bending cam follower 255 rises in the Z-axis direction together with the component holding member 243. Thereby, the cut first and second leads R1 and R2 held by the first and

second holding walls

243a and 243b are pushed down by the first and

second bending members

248 and 249 and bent.

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 is positioned at a part supply position protruding from the upper surface of the apparatus main body 250 of the cutting / bending apparatus 240. Then, the air cylinder 265 is operated in the contraction direction (Z-axis direction), and the first and

second clampers

263 and 264 are rotated about the rotation axis C in the clockwise direction of FIG. , 264 are spaced apart from the upper parts of the first and

second holding walls

243a, 243b.

The axial component P positioned at the component supply position is picked up by the gripping claws of the component mounting head 38 of the component mounting apparatus 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. Thereafter, the operation of one cycle is repeated for each axial component P. On the other hand, as shown in FIG. 14, the first and second tapes T 1 and T 2 including the tip portions of the first and second leads R 1 and R 2 separated from the axial component P are discharged from the tip of the feeder body 210. The air is gradually discharged downward in the duct D. Then, the first and second tapes T1 and T2 are cut into a predetermined length by a cutter (not shown), and dropped into a tape recovery box (not shown) provided below the discharge duct D and collected.

second feed members

223 and 223 moved to the retreat position. The feed holding member 282 is hooked and locked to 224.

Next, as shown in FIGS. 15C and 15D, the operator pushes the urging release lever 285 downward to rotate the unit pressing urging member 284 in the urging releasing direction, and the unit pressing member 283 is moved to the unit mechanism 300. Rotate in a direction to release from the locking member 301. Then, as shown in FIGS. 15E and 15F, the operator tilts the unit mechanism 300 in the direction toward the upstream side of the feeding and pulls it upward in that state as shown in FIG. 15G. As described above, as shown in FIG. 15H, the operator can extract the unit mechanism 300 from the feeder main body 210.

Then, the operator cuts the new unit mechanism 300 to be replaced into the feeder main body 210 from above in a procedure reverse to the above-described procedure, that is, in a state where the new unit mechanism 300 is tilted toward the upstream side of feeding. -Insert to a position where it can be bent, pull up the bias release lever 285, rotate the unit pressing biasing member 284 in the engagement direction of the unit pressing member 283, and lock the unit pressing member 283 to the unit mechanism 300. Engage with member 301. Then, the operator removes the feed pressing member 282 from the first and

second feeding members

223 and 224, and moves the first and

second feeding members

223 and 224 to the feeding position toward the feeding downstream side. As described above, the operator can insert the new unit mechanism 300 into the feeder main body 210.
