The frame 202 is configured to extend upward from both ends of the base table 201 in the rotation axis direction (A direction parallel or substantially parallel to the X direction) of the reel 400 held by the reel holding unit 203. The reel holder 203 and the feeder holder 204 are fixed from both sides in the X direction by a frame 202. A gap H in a predetermined height direction (see FIG. 6) is provided between the base table 201 and the reel holder 203 fixed by the frame 202. In the present embodiment, a waste tape recovery box 500 for recovering a carrier tape 400a that is discarded after the component 120 is supplied to the surface mounter 100 is placed between the base table 201 and the reel holder 203. It is possible. As described above, since the reel holding unit 203 is supported by the frames 202 extending upward from both ends of the base table 201 in the X direction, the space between the base table 201 and the reel holding unit 203 is in the forward direction (arrow Y1). Direction). As a result, the user can pull out the waste tape collection box 500 in the forward direction (opposite to the surface mounter 100) while the collective change cart 200 is mounted on the surface mounter 100. The base table 201 is an example of the “storage unit” in the present invention.

  As shown in FIGS. 4 to 7, the reel holding unit 203 includes a pair of side plates 210 fixed to the frame 202, two support rollers 221 and 222 supported at the lower part of the pair of side plates 210, and a pair of side plates 210. A sheet metal member 223 fixed to the lower side of the side plate 210, one support roller 230 supported on the side of the pair of side plates 210 on the arrow Y2 direction side, and one support roller supported on the top of the pair of side plates 210 240, a plurality of reel support portions 250 rotatably attached to the support roller 240, and a sheet metal member 260 fixed to the pair of side plates 210 in the vicinity of the support roller 240.

  The two support rollers 221 and 222 supported at the lower part of the pair of side plates 210 each have a plurality of unit rollers having a predetermined width continuously from one side plate 211 (see FIG. 7) to the other side plate 212. The roller shafts 221a and 222a are attached. In the two support rollers 221 and 222, the unit rollers adjacent to each other are attached at an appropriate interval so that the reel 400 is not sandwiched. As shown in FIG. 6, the two support rollers 221 and 222 are arranged at a predetermined interval in the Y direction, and the reel 404 or 13 inch having a diameter of 15 inches is formed by the two support rollers 221 and 222. It is possible to support a reel 403 having a diameter. 4 to 6, the sheet metal member 223 fixed to the lower sides of the pair of side plates 210 has a tip portion 223a bent upward, and the bent tip portion 223a includes two support rollers.

The reel 402 having a diameter of 10 inches or the reel 401 having a diameter of 7 inches can be supported by the front end portion 223a of the sheet metal member 223 and the support roller 222. The support roller 221, the support roller 222, and the tip end portion 223a of the sheet metal member 223 are examples of the “second support member”, the “first support member”, and the “third support member” of the present invention, respectively. The reel 404 having a diameter of 15 inches and the reel 403 having a diameter of 13 inches are large because the reel itself is large and the parts 120 accommodated in the carrier tape 400a wound around the reel 404 or 403 are also large. Therefore, the reel (reel 404 or 403) is difficult to rotate when the carrier tape 400a is fed out to supply the component 120. For this reason, the reel 404 or the reel 403 is supported by the two support rollers 221 and 222 in which both portions that support the reel (reel 404 or 403) are configured to be rotatable. Accordingly, it is possible to support the reel 404 or the reel 403 having a large weight so that the reel 404 or the reel 403 can be easily rotated. On the other hand, the reel 402 having a diameter of 10 inches and the reel 401 having a diameter of 7 inches have a small weight because the reel itself is small and the component 120 accommodated in the reel (reel 401 or 402) is also small. Therefore, when the carrier tape 400a is fed out to supply the component 120, the reel (reel 401 or 402) may rotate too much. For this reason, the reel 402 or the reel 401 includes a support roller 222 that can rotate a portion that supports the reel (reel 401 or 402) and a tip portion of the sheet metal member 223 that does not rotate the portion that supports the reel (reel 401 or 402). 223a. Accordingly, it is possible to support the reel 402 or the reel 401 having a small weight while appropriately suppressing the rotation of the reel 402 or the reel 401. A reel support portion 203a (FIGS. 4 to 5) capable of holding reels 401 to 404 having a diameter of 15 inches to 7 inches in diameter by the two support rollers 221 and 222 and the tip end portion 223a of the sheet metal member 223. 6). The reel support portion 203a is an example of the “first reel support portion” in the present invention.

  Further, the support roller 230 is configured by attaching a plurality of unit rollers having a predetermined width to the roller shaft 231 continuously from one side plate 211 to the other side plate 212. In the support roller 230, the unit rollers are attached so that the unit rollers adjacent to each other are arranged at a minute interval. Here, as shown in FIGS. 5 and 7, a partition plate 600 for partitioning the reel 400 (reels 401 to 404) held by the reel support portion 203a can be attached to the reel support portion 203a. . As shown in FIG. 5, the partition plate 600 includes an engagement portion 601 that engages with the roller shaft 231 of the support roller 230, and cutout portions 602 and 603 formed at positions corresponding to the two support rollers 221 and 222, respectively.

The engaging portion 601 of the partition plate 600 is held between the adjacent unit rollers of the support roller 230, and the lower portion of the notch 602 is supported by the groove 271 of the partition plate support portion 270 so that the partition plate 600 is moved in the X direction. It is possible to attach while positioning.

  Similarly to the support roller 230, the support roller 240 is configured by attaching unit rollers to the roller shaft 241 so that adjacent unit rollers are arranged at a minute interval. The reel support portion 250 includes a pair of side plates 251 rotatably attached to the roller shaft 241 of the support roller 240, and two support portions 252 and 253 attached between the pair of side plates 251 below the side plate 251. Including. The pair of side plates 251 are attached to the roller shaft 241 so as to sandwich one unit roller. The two support portions 252 and 253 are arranged at a predetermined interval, and the two support portions 252 and 253 can support only the reel 401 having a diameter of 7 inches. A distance D (see FIG. 7) between the pair of side plates 251 is configured to be larger than the width of the reel 401 having the maximum width among the reels 401 having a diameter of 7 inches. Accordingly, the reel 401 having a diameter of 7 inches can be supported by the reel support portion 250 regardless of the width W (see FIG. 8). The reel support portion 250 is an example of the “second reel support portion” in the present invention.

  As shown in FIG. 6, the sheet metal member 260 is formed in an L shape when viewed from the X direction. In the present embodiment, by rotating the reel support portion 250 in the direction of arrow A1, the edge of the side plate 251 of the reel support portion 250 and the contact surface 261 of the sheet metal member 260 are brought into contact with each other to retract the reel support portion 250. It is possible to hold the position P1. In a state where the reel support portion 250 is located at the retracted position P1, a reel 404 having a diameter of 15 inches is supported on the reel support portion 203a in an area immediately below the reel support portion 250 (the same position in the X direction). In addition, since the reel support portion 250 and the reel 404 do not interfere with each other, the reel support portion 203a can hold the reels 400 (reels 401 to 404) of all sizes. Further, by rotating the reel support portion 250 in the arrow A2 direction, the edge of the side plate 241 of the reel support portion 250 and the contact surface 262 of the sheet metal member 260 are contacted to bring the reel support portion 250 to the support position P2. It is possible to hold. In the support position P2, the reel support part 250 can support the reel 401 having a diameter of 7 inches by the two support parts 252 and 253. In the state where the reel support portion 250 is located at the support position P2, the reels 402 to 404 having a diameter of 10 inches to 15 inches in the reel support portion 203a in the region immediately below the reel support portion 250 (the same position in the X direction). If the reel support portion 250 and the reels 402 to 404 interfere with each other, and the reel support portion 250 supports the reel 401 having a diameter of 7 inches, the reel support portion 250 and the reel 401 are connected to each other. Does not interfere. For this reason, in the state where the reel support portion 250 is located at the support position P2, the reel support portion 250 holds the reel 401 having a diameter of 7 inches and the area immediately below the reel support portion 250 (in the X direction). In the same position), the reel 401 having a diameter of 7 inches can also be supported by the reel support portion 203a. Note that the partition plate 600 does not interfere with the reel support portion 250 when the reel support portion 250 is located at either the retracted position P1 or the support position P2.

  In the present embodiment, when the reel 401 is supported by the reel support portion 203a and the reel support portion 250 at the support position P2, each reel 401 is about 15 inches from the reel support portion 203a when viewed from the X direction. When the reel 404 having a diameter is supported, the reel 404 is positioned so as to largely overlap the reel 404. That is, by making full use of the space for holding the reel 404 having a diameter of 15 inches, the space viewed from the X direction is substantially the same as the space for holding the reel 404 having a diameter of about 15 inches. Two reels 401 are held.

  Further, the reel support portion 250 is positioned above the reel support portion 203a when it is positioned at either the retracted position P1 or the support position P2.

  As shown in FIGS. 4, 6, and 7, the unit roller of the support roller 240 guides the carrier tape 400a fed from the reel 400 supported by the reel support portion 203a and the reel support portion 250 to guide the tape feeder. 300. Further, when the reel 401 is held on the reel support 203a in the region immediately below the reel support 250 with the reel support 250 positioned at the support position P2, the reel 401 is fed from the reel 401 supported by the reel support 203a. The carrier tape 400a is guided by the support portion 252 of the reel support portion 250 and the support roller 240 and guided to the tape feeder 300. As shown in FIG. 7, when the reel 401 is held on the reel support 203a in the area immediately below the reel support 250 with the reel support 250 holding the reel 401 at the support position P2, the reel support The reel 401 supported by the portion 203a and the reel 401 supported by the reel support portion 250 can be arranged shifted in the X direction. Thereby, it is suppressed that the carrier tape 400a sent out from each reel 401 overlaps.

  Further, as shown in FIGS. 2 and 3, the feeder holding unit 204 is configured to be capable of mounting a plurality of tape feeders 300. Further, as shown in FIG. 8, the tape feeder 300 sucks the component 120 held by the carrier tape 400a by the head unit 20 of the surface mounter 100 by sending out the carrier tape 400a wound around the reel 400. It has the function to supply to the position (component supply part 301) which can be performed. Specifically, the carrier tape 400a holds the parts 120 at a predetermined interval, and is provided with engagement holes (not shown) at a predetermined interval. When the sprocket 302 is rotated in a state where the teeth of the sprocket 302 and the engagement holes of the carrier tape 400a are engaged, the carrier tape 400a is fed out in the arrow Y2 direction. As a result, the components 120 held on the carrier tape 400 a are sequentially supplied to the component supply unit 301. As the carrier tape 400a is sent out, the reel 400 held by the reel holding portion 203 of the batch exchanging carriage 200 is rotated. The rotation axis direction (arrow A direction) of the reel 400 is parallel or substantially parallel to the X direction.

  Next, the mounting operation of the component 120 on the printed circuit board 110 by the surface mounter 100 of the present embodiment will be described with reference to FIGS. 1 and 2.

  First, the user places the reel 400 that stores the necessary components 120 on the printed circuit board 110 to be mounted and the tape feeder 300 corresponding to the reel 400 in advance on the collective exchange cart 200. Then, as shown in FIG. 1, the collective exchange cart 200 is mounted on the mounting portion 100 b of the surface mounter 100. The mounting operation is started in this state.

First, as shown in FIG. 2, the printed circuit board 110 is carried onto the base 1 via the pair of board transport conveyors 10 and is transported to the mounting work position at the center of the base 1. In parallel with the loading operation of the printed circuit board 110, the component 120 to be mounted is supplied from the tape feeder 300 by the head unit 20. Specifically, when the head unit 20 is moved above the tape feeder 300, the suction nozzle 22 of the head unit 20 is disposed above the component 120 to be mounted that is held by the tape feeder 300. Thereafter, the suction nozzle 22 is lowered, and negative pressure is supplied to the tip of the suction nozzle 22 at a predetermined timing. Thereby, the component 120 on the tape feeder 300 is sucked and held by the suction nozzle 22. Next, the suction nozzle 22 holding the component 120 is raised, and the head unit 20 is moved to the mounting position above the printed circuit board 110. As shown in FIG. 2, after the head unit 20 is moved to the mounting position of the printed circuit board 110, the suction nozzle 22 is lowered and the component 120 is mounted on the printed circuit board 110. By the above processing is performed repeatedly to attachment to printed circuit board 110 of the part 120 is performed. In addition, the printed circuit board 110 on which the mounting of the component 120 is completed is carried out from the base 1 via the pair of board conveyance conveyors 10. In this way, the mounting operation of the component 120 by the surface mounter 100 is completed.

  During the mounting operation described above, the waste tape after the component 120 is taken out from the carrier tape 400a is accumulated in the waste tape collection box 500 placed on the base table 201 of the batch exchanging carriage 200. Therefore, it is necessary to sequentially dispose of the waste tape collected in the waste tape collection box 500 during the mounting operation. Here, in this embodiment, since the user can pull out the waste tape collection box 500 in a state where the collective exchanging cart 200 is mounted on the surface mounter 100, the surface mounter 100 is mounted. During the process, the waste tape collection box 500 can be pulled out to dispose of the waste tape.

  In the present embodiment, as described above, the reel support portion 203a that can support any of the reels 401 to 404 having a diameter of about 7 inches to about 15 inches, the retreat position P1, and the support position P2 are moved. A reel having a diameter of about 15 inches by the reel support portion 203a by moving the reel support portion 250 to the retracted position P1 by providing the reel support portion 250 configured to be capable of supporting the reel 401. 404 can be held. Also, by moving the reel support portion 250 to the support position P2, the reel support portion 203a and the reel support portion 250 can support the reel 401 having a diameter of about 7 inches, respectively, so that at the same position in the X direction. The two reels 401 can be held in a line on the YZ plane. Accordingly, while holding one reel 401 to 404 as viewed from the X direction by a part of the reel support portion 203a, the reel support portion 203a and the reel support portion 250 at the support position P2 in the other region of the reel support portion 203a. Thus, the two reels 401 can be held side by side on the YZ plane at the same position in the X direction.

  In the present embodiment, as described above, when the reel 401 is supported by the reel support portion 203a and the reel support portion 250 at the support position P2, the reel 401 and the reel support portion supported by the reel support portion 203a, respectively. Both reels 401 supported by 250 are configured to be positioned so as to overlap with the reel 404 in a state where the reel 404 is supported by the reel support portion 203a when viewed from the X direction. The reel 404 to be supported and the two reels 401 supported by the reel support portion 203a and the reel support portion 250 at the support position P2 can be arranged in an overlapping region. Thereby, it can suppress that the size of the collective change cart 200 becomes large.

  Further, in the present embodiment, as described above, the reel 404 is supported by the support roller 222 and the support roller 221, and the reel 401 is supported by the support roller 222 and the tip end portion 223 a of the sheet metal member 223. When the reel 404 is supported by the roller 222 and the support roller 221, the reel 401 can be easily supported by the support roller 222 and the tip end portion 223 a of the sheet metal member 223 in a region overlapping with the reel 404 when viewed from the X direction. Thereby, since the part holding the reel 401 and the part holding the reel 404 do not shift in the YZ plane, it is possible to easily suppress the size of the batch exchanging carriage 200 from increasing in the YZ plane.

  In the present embodiment, as described above, the retraction position P1 and the support position P2 of the reel support part 250 are set to positions above the reel support part 203a, whereby the reel support part 250 is moved from the reel support part 203a. However, unlike the case of retracting downward, it is not necessary to secure a space for retracting the reel support portion 250 below the reel support portion 203a. Accordingly, the waste tape collection box 500 for collecting the waste tape of the carrier tape 400a that is discarded after the component 120 is supplied to the surface mounter 100 can be easily disposed below the reel support portion 203a. .

  In the present embodiment, as described above, the reel support portion 250 supports one reel 401 as viewed from the X direction, and the reel support portion 203a supports one reel 401 as viewed from the X direction. When the reel holding unit 203 holds two reels 401 arranged in the YZ plane at the same position in the X direction and viewed from the X direction, one of the two reels 401 can be supported by the reel support unit 203a. Therefore, the reel support portion 250 can be configured to support only one reel 401. Thereby, unlike the case where the reel support portion 250 is configured to be able to support the two reels 401, it is possible to suppress an increase in the size of the reel support portion 250. Thereby, since the space for the reel support part 250 to move to the retracted position P1 can be reduced, it is possible to suppress the bulk exchanging cart 200 from becoming large.

  In the present embodiment, as described above, the unit roller for guiding the carrier tape 400a fed from the reel 400 supported by the reel support portion 203a and the reel support portion 250 is provided on the roller shaft 241 of the support roller 240. By attaching, the carrier tape 400a delivered from the reel 400 can be guided using the roller shaft 241 of the support roller 240 for moving the reel support portion 250 to the retracted position P1 and the support position P2.

  In the present embodiment, as described above, the collective exchange cart is configured such that the user can pull out the waste tape collection box 500 in a state where the collective exchanging cart 200 is mounted on the surface mounter 100. Since the waste tape collection box 500 can be pulled out without removing the 200 from the surface mounter 100, the waste tape in the waste tape collection box 500 can be processed without stopping the mounting operation of the surface mounter 100. Thereby, a user's convenience can be improved.
