The two component cases 100 are fitted and fixed in the two concave portions 170 of the feeder main body 106. Therefore, as shown in FIGS. 6 and 17, positioning pins 390 and 392 protrude from the bottom surface of each recess 170 perpendicular to the width direction of the feeder main body 106 at two locations separated in the diagonal direction, respectively. Yes.

In the present bulk feeder 96, attachment and removal of the component case 100 to and from the feeder main body 106 are performed by an operator with the bulk feeder 96 removed from the holding base 80. When attaching the component case 100 to the feeder main body 106, the operator fits the component case 100 into the recess 170 in the width direction of the feeder main body 106, and engages the positioning pins 390 and 392 in the positioning holes 298 and 300. The shaft portion 258 is fitted into the through hole 144 of the turntable 130. The component case 100 is fixed to the feeder body 106 made of a magnetic material by the magnetic force of the permanent magnet 296, and the case member 250 is brought into close contact with the bottom surface of the recess 170 as shown in FIG.

Further, in the present embodiment, the through hole 172 and the pressing member 178 constitute a rotating disk holding part.

In a state where the two component cases 100 are respectively fitted in the recesses 170 and fixed to the feeder main body 106, as shown in FIG. 17, the case member 250 side is back-to-back with the turntable 130 interposed therebetween, and each component supply The portions 346 are aligned on a straight line parallel to the width direction of the feeder body 106 and are in a single plane. Moreover, the direction of each component guide groove 270 of the two component cases 100 is reversed. The positioning holes 298, 300 of the component case 100 and the positioning pins 390, 392 of the two recesses 170 of the feeder main body 106 are reversed around an axis extending perpendicularly to the rotation axis of the turntable 130 and extending vertically. Both of the two component cases 100 attached to the feeder main body 106 are provided so as to be fitted to each other to position the component case 100. In a state where the bulk feeder 96 is attached to the holding table 80, as schematically shown in FIG. 19, the component supply portions 346 of the component cases 100 of the plurality of bulk feeders 96 are aligned on a straight line parallel to the X-axis direction.

The parts 272 are not in contact with the turntable 130 by being separated by the partition plate portion 253. Moreover, the increase in the width | variety of the feeder main body 106 is suppressed by this insertion. When removing the component case 100 from the feeder main body 106, the operator moves the component case 100 in such a direction as to overcome the magnetic force and away from the feeder main body 106 in the width direction of the feeder main body 106. As a result, the parts case 100 is removed from the feeder body 106 while leaving the rotating plate 130, the rotation drive device 132 (the whole component moving device 102) and the controller 104 in the feeder body 106. In the present embodiment, the component moving device 102 and the controller 104 are shared by the two component cases 100.

The tape feeder 98 is a component feeder that supplies electronic circuit components while being held on a component holding tape, and the feeder main body 400 (see FIG. 2) is similar to the feeder main body 106 of the bulk feeder 96. It is comprised so that it may be positioned and fixed to. Accordingly, at least one of the bulk feeder 96 and the tape feeder 98 can be held on one holding stand 80. For example, as shown in FIG. 1, among the plurality of mounting modules 10, an electronic circuit component is supplied by a bulk feeder 96 in the uppermost mounting module 10, and an electronic circuit component is supplied by a tape feeder 98 in the other mounting modules 10. Is supplied.

Further, the controller 32 of the mounting module 10 is configured mainly by a computer, and controls the substrate transfer device 20 and the like, and exchanges commands and information with the controller 104 of the bulk feeder 96.

In this bulk feeder 96, if the same type of component 272 is accommodated in two component cases 100, the component 272 is supplied by one component case 100, and the component 272 of the component case 100 disappears, the other component case 100 100 supplies the part 272. The bulk feeder 96 includes a spare part case 100. However, different types of electronic circuit components mounted on different types of circuit boards 40 may be accommodated in the two component cases 100, respectively.

In this bulk feeder 96, the direction of each component guide groove 270 of the two component cases 100 attached to the feeder main body 104 is opposite, and the component 272 in one component case 100 is rotated when the turntable 130 is rotated. Is not sent in the other component case 100. Therefore, the turntable 130 is rotated in the component case 100 for supplying the component 272 in the direction in which the component 272 is sent (clockwise in FIG. 10), so that the component 272 is in the component housing chamber 334 in the component case 100. To the parts take-out port 344. In the rotating disk 130, the eight permanent magnets 162 are attached to the bottom wall of the recess 260 outside the component case 100 by fitting the protrusion 142 in which the permanent magnet 162 is embedded into the annular recess 260 of the component case 100. It is made to adjoin to the component guide groove 270 through the thin part 268 which comprises. Further, the component guide groove 270 formed in the thin portion 268 of the case member 250 extends along the rotation trajectory of the eight permanent magnets 162. Therefore, when the magnetic force of the permanent magnet 162 acts on the component 272, the rotating disk 130 is rotated along the component guide groove 270 in the direction from the lower part of the component accommodating unit 336 toward the component supply unit 346. The component 272 attracted by the permanent magnet 162 is moved from below to above in the component storage chamber 334.

A plurality of parts 272 are moved along the part guide groove 270, but when reaching the groove crossing part 340, a part 272 having no part inside the part guide groove 270, or only a part of the part 272 enters the part guide groove 270. The contained component 272 is scraped off by a plane 330 perpendicular to the component guide groove 270 and is prevented from entering the passage 342. Only the part 272, which is entirely accommodated in the part guide groove 270, enters the passage 342 without being obstructed by the flat surface 330, and is moved to the part take-out port 344 while being aligned in a row. The partial cylindrical surface 326 constituting the inner wall surface 324 of the component storage chamber 334 is closer to the component guide groove 270 as the portion is closer to the plane 330, and the component guide groove 270 is moved as the component 272 is moved to the plane 330 side. To the side, and the housing in the component guide groove 270 is promoted.

Of the parts 272 that have entered the passage 342, the leading part 272 located on the most downstream side contacts the upstream end in the part feed direction of the stopper pin 274, and reaches the part take-out position located in the part take-out port 344. Be stopped. The turntable 130 is intermittently rotated by an angle equal to the arrangement angle interval of the eight permanent magnets 162, and as shown schematically in FIG. 20, the two adjacent permanent magnets 162 are connected to the component outlet 344. It is stopped at a stop position that is equiangular on both sides. In this state, of the two permanent magnets 162 located on both sides of the component outlet 344, the permanent magnet 162 on the downstream side in the rotational direction indicated by the arrow in FIG. The upstream permanent magnet 162 is opposed to the rear portion (downstream end in the component feeding direction), and is separated from the leading component 272 upstream. Therefore, the leading component 272 is attracted to the stopper pin 274 by the magnetic attractive force of the magnetic flux of the permanent magnet 162 guided by the stopper pin 274 made of a magnetic material, and is maintained in a state where it is positioned at the component extraction position. The magnetic attractive force of the upstream permanent magnet 162 acts on the second and subsequent parts 272 and is attracted to the side surface of the part guide groove 270 on the side of the partition plate 253, and is kept in an aligned state.

Also, the upper end portion of the protrusion 142 fitted into the recess 260 of the turntable 130 is protruded from the upper surface of the case member 250 as shown by a two-dot chain line in FIG. This protrusion is allowed by the opening 264, and a state where the cam portion 152 faces the shutter 360 is obtained. As the turntable 130 rotates, the inclined surface 156 of the cam portion 152 engages with the inclined surface 372 of the cam follower 370 of the shutter 360, and the arm portion 366 is moved in the direction of retracting into the recess 362 by the action of the inclined surface. As a result, the shield 368 is retracted from the notch 282 into the recess 362, the component outlet 344 is opened, and the component 272 is taken out by the suction nozzle 70. When the turntable 130 is stopped at the stop position, the flat surface 154 engages with the cam follower 370 as shown in FIG. 9B, and the shutter 360 opens the component outlet 344. To be kept.

The phase of the rotational position detection device 220 with respect to the gear 210 of the detected object 222 is detected by the sensor 224 when one of the four dogs 228 is in a state where the rotating disk 130 is stopped at any of the eight stop positions. Adjusted to phase. Then, the motor 200 is controlled with the position where any one of the dogs 228 is detected by the sensor 224 as the origin position, and the turntable 130 is intermittently rotated by 1/8 turn.

The mounting head 50 is moved to the component case 100 that supplies the component 272 of the bulk feeder 96 that receives the component 272 according to the mounting program, and is lowered while the suction nozzle 70 is positioned on the component extraction port 344. Part 272 is adsorbed through outlet 344. At this time, the notch 374 prevents interference between the portion of the suction nozzle 70 that holds the suction pipe and the case member 252. Then, the suction nozzle 70 is raised, and the component 272 is taken out upward from the component outlet 344 opened upward. After taking out the parts, the turntable 130 is rotated, and the next part 272 is sent to the part takeout port 344. As the turntable 130 rotates, the cam follower 370 comes off the flat surface 154 and is positioned in the recess 150 as shown in FIG. 9A, and the component outlet 344 is closed by the shielding portion 368. When 130 is next stopped, the parts outlet 344 is opened again. In the case of the component case 100 that does not supply the component 272, the component 272 is not sent, but the cam unit 152 engages with the cam follower 370 and moves the arm unit 366 as the turntable 130 rotates, and the shielding unit 368 is moved. As a result, the component outlet 344 is opened and closed.

When one component case 100 is empty and the component 272 is supplied by the other component case 100, the rotation direction of the turntable 130 is reversed. The two component cases 100 are the same, and are attached to the feeder main body 106 in a state where they face each other. Therefore, the direction of the component guide groove 270 is reversed, whereas the turntable 130 is shared by the two component cases 100. This is because. In the cam surface 160, inclined surfaces 156 are formed symmetrically on both sides of the flat surface 154, and the shutter 360 can be driven in the same manner even if the rotating disk 130 is rotated in either the forward or reverse direction.

The feeder body may be made of a non-magnetic material, and a permanent magnet may be provided in a part facing the permanent magnet of the part case, or the part may be made of a magnetic material to adsorb the part case.

The part case may be moved upward and removed from the feeder body. Further, the rotating disk may be rotatably held by the feeder main body with the rotation axis positioned. Those embodiments will be described with reference to FIGS.
Also in the bulk feeder 450, as in the bulk feeder 96, the two component cases 452 are held side by side in the X-axis direction by the feeder main body 454, and the rotating plate 462 of the component moving device 460 is the same as the rotating plate 130. The two component cases 452 are shared, and the component moving device 460 is shared. Therefore, as shown in FIGS. 21 and 22, the feeder main body 454 is formed with two concave portions 464 that open on the top surface and both side surfaces, respectively, and through holes 466 that penetrate the bottom portions of the two concave portions 464. The turntable 462 is formed so as to be rotatable about an axis parallel to the width direction of the feeder main body 454.

The turntable 462 is configured in the same manner as the turntable 130, and is rotatably supported by two roller 470 with a hook as a rotation support member and a gear 474 of the rotation drive device 472 of the component moving device 460. Components having the same functions as those of the component case 100 and the turntable 130 of the component case 452 and the turntable 462 are assigned the same reference numerals and used for the description.
