Further, the belt conveying device 20 includes: a motor 24 generating power for driving the 1 st belt 21 and the 2 nd belt 22; a 1 st gear 25 coupled to the 1 st belt 21; and a 2 nd gear 26 coupled to the 2 nd belt 22.

The 1 st belt 21 conveys the component C supplied from the ramp component 40. The 1 st position P1 is defined at the rear of the slope member 40. The 2 nd position P2 is defined at a position rearward of the 1 st position P1. The 1 st position P1 includes a position where the component C is fed from the lower end portion of the ramp component 40. The 2 nd position P2 includes a position of the 1 st belt 21 opposed to the return guide member 23. As shown by an arrow R1 in fig. 4, the 1 st belt 21 conveys the component C supplied to the 1 st position P1 rearward. The 1 st belt 21 transports the component C from the 1 st position P1 to the 2 nd position P2.

The 1 st belt 21 is an endless belt. The 1 st belt 21 is supported by a drive pulley 21D and a plurality of driven pulleys 21P.

The motor 24 is coupled to the drive pulley 21D via a gear not shown. When the drive pulley 21D is rotated by the driving of the motor 24, the 1 st belt 21 is rotated in a state of being supported by the drive pulley 21D and the plurality of driven pulleys 21P. The 1 st belt 21 rotates to convey the component C rearward.

An intermediate position P5 of the 1 st belt 21 is defined between the 1 st position P1 and the 2 nd position P2. The 1 st belt 21 includes a ramp 211 between the 1 st position P1 and the intermediate position P5 and a flat 212 between the intermediate position P5 and the 2 nd position P2. The slope portion 211 is inclined upward from the 1 st position P1 toward the intermediate position P5.

The return guide member 23 guides the component C supplied to the 2 nd position P2 to the 3 rd position P3. The return guide member 23 guides the component C to feed the component C conveyed by the 1 st belt 21 to the 2 nd belt 22. The 3 rd position P3 is defined to be located leftward (-X direction) relative to the 2 nd position P2. The 3 rd position P3 includes a position of the 2 nd belt 22 opposite to the return guide member 23. The return guide member 23 is supported by at least a part of the main frame 11. The return guide member 23 is disposed above the 1 st belt 21 and the 2 nd belt 22. The return guide member 23 is separated from the 1 st belt 21 and the 2 nd belt 22.

The height of the 1 st tape 21 at the 2 nd position P2 is the same as or higher than the height of the 2 nd tape 22 at the 3 rd position P3 than the height of the 2 nd tape 22 at the 3 rd position P3. That is, the 1 st tape 21 at the 2 nd position P2 is disposed on the same plane as the 2 nd tape 22 at the 3 rd position P3 or above the 2 nd tape 22 at the 3 rd position P3. Since the height of the 1 st tape 21 at the 2 nd position P2 is the same as or higher than the height of the 2 nd tape 22 at the 3 rd position P3, the component C can be smoothly transferred from the 1 st tape 21 to the 2 nd tape 22.

The 2 nd belt 22 conveys the component C supplied from the 1 st belt 21. The 2 nd belt 22 is disposed on the left side (-X side) of the 1 st belt 21. The 2 nd belt 22 is disposed parallel to the 1 st belt 21 in the XY plane. The component C is fed from the 2 nd position P2 of the 1 st tape 21 to the 3 rd position P3 of the 2 nd tape 22 by the return guide member 23. As shown by an arrow R2 in fig. 4, the 2 nd belt 22 conveys the component C supplied to the 3 rd position P3 forward. The 2 nd belt 22 transports the component C from the 3 rd position P3 to the 4 th position P4. The 4 th position P4 is defined ahead of the 3 rd position P3.

The 2 nd belt 22 is an endless belt. The 2 nd belt 22 is supported by a drive pulley 22D and a plurality of driven pulleys 22P.

The 1 st gear 25 and the 2 nd gear 26 are rotatably supported by a support member 27. The support member 27 is supported by at least a part of the main frame 11. The support member 27 is disposed rearward of the return guide member 23.

The 1 st gear 25 is coupled to at least one of the driven pulleys 21P supporting the 1 st belt 21. In the present embodiment, the 1 st gear 25 is coupled to the driven pulley 21P disposed at the rearmost position among the plurality of driven pulleys 21P. The 1 st gear 25 rotates together with the driven pulley 21P coupled to the 1 st gear 25. The 1 st gear 25 and the driven pulley 21P coupled to the 1 st gear 25 are rotatably supported by a support member 27.

The 1 st gear 25 is coupled to the 1 st belt 21 via a driven pulley 21P. When the 1 st belt 21 is rotated by the driving of the motor 24, the 1 st gear 25 coupled to the 1 st belt 21 via the driven pulley 21P rotates in synchronization with the 1 st belt 21.

The 2 nd gear 26 is disposed in front of the 1 st gear 25. The 2 nd gear 26 meshes with the 1 st gear 25. The 2 nd gear 26 is coupled to the drive pulley 22D. The 2 nd gear 26 rotates together with the drive pulley 22D coupled to the 2 nd gear 26. The 2 nd gear 26 and the drive pulley 22D coupled to the 2 nd gear 26 are rotatably supported by the support member 27.

The 2 nd gear 26 is coupled to the 2 nd belt 22 via the drive pulley 22D. When the 1 st gear 25 is rotated by the rotation of the 1 st belt 21, the 2 nd gear 26 engaged with the 1 st gear 25 is rotated in synchronization with the 1 st gear 25. When the 2 nd gear 26 rotates, the 2 nd belt 22 coupled to the 2 nd gear 26 via the drive pulley 22D rotates in synchronization with the 2 nd gear 26.

In this way, in the present embodiment, both the 1 st belt 21 and the 2 nd belt 22 are driven by the power generated by the 1 motor 24. The 1 st belt 21 and the 2 nd belt 22 are coupled via a 1 st gear 25 and a 2 nd gear 26. The 2 nd belt 22 rotates in synchronization with the 1 st belt 21.

When the 1 st gear 25 rotates in the direction indicated by the arrow Ra in fig. 5 by the rotation of the 1 st belt 21, the 2 nd gear 26 rotates in the direction opposite to the rotation direction of the 1 st gear 25 as indicated by the arrow Rb in fig. 5. Thereby, the 1 st belt 21 rotates to convey the member C backward, and the 2 nd belt 22 rotates to convey the member C forward.

In the present embodiment, the conveying speed of the component C by the 1 st belt 21 is lower than the conveying speed of the component C by the 2 nd belt 22. In the present embodiment, the gear ratio of the 1 st gear 25 to the 2 nd gear 26 is less than 1. That is, the number of teeth of the 2 nd gear 26 is smaller than that of the 1 st gear 25. The conveying speed of the 1 st belt 21 is lower than the conveying speed of the 2 nd belt 22 according to the gear ratio of the 1 st gear 25 to the 2 nd gear 26. Since the conveying speed of the 1 st belt 21 is lower than the conveying speed of the 2 nd belt 22, the component C can be smoothly transferred from the 1 st belt 21 to the 2 nd belt 22. Since the component C is conveyed at a high speed after being carried on the 2 nd belt 22, the accumulation of the component C disappears. Therefore, the component C is smoothly conveyed.

The belt conveying device 20 further includes a guide member 28, and the guide member 28 is disposed between the 3 rd position P3 and the 4 th position P4 and guides the member C forward. The guide member 28 is disposed on the left side (-X side) of the 2 nd belt 22. The guide member 28 suppresses the component C conveyed on the 2 nd belt 22 from falling from the 2 nd belt 22 to the-X side.

In addition, the belt conveying device 20 has a component full sensor 91 that detects the amount of the components C in the slope portion 211 and a component full sensor 92 that detects the amount of the components C in the flat portion 212. The component full state sensor 91 and the component full state sensor 92 may be optical sensors that detect the amount of the component C by emitting detection light, or may be contact sensors that detect the amount of the component C by bringing a probe into contact with the component C. Whether the component C is in the full state is detected based on the detection data of the component full sensor 91 and the detection data of the component full sensor 92.

The 1 st conveyance member 32A, the 2 nd conveyance member 32B, and the 3 rd conveyance member 32C each have a conveyance surface that contacts the member C.

The vibrator 33 supports the conveying member 32. The vibrator 33 includes, for example, a piezoelectric member, and vibrates the conveying surface. The conveying surface is slightly vibrated by the vibrator 33 so that the member C in contact with the conveying surface is conveyed forward.

The pickup position PP is defined at the leading end portion of the 3 rd conveyance member 32C. The stopper member 34 is disposed at a position forward of the pickup position PP. The component C conveyed to the pickup position PP by the 3 rd conveyance component 32C hits the stopper component 34 to be positioned at the pickup position PP. The mounting head 5 holds the component C positioned at the pickup position PP by the stopper component 34 with the suction nozzle 4.

The jigging conveyer 30 further includes a guide member 35 for guiding the member C conveyed to the 1 st conveying member 32A forward. The guide member 35 is disposed on the left side (-X side) of the conveyance surface 31 of the 1 st conveyance member 32A. The guide member 35 suppresses the component C conveyed to the 1 st conveying member 32A from falling from the 1 st conveying member 32A toward the-X side.

The vibration transport device 30 further includes a component presence sensor 93 that detects the presence or absence of the component C at the pickup position PP. The component presence sensor 93 may be an optical sensor that detects the presence or absence of the component C by emitting detection light, or a contact sensor that detects the presence or absence of the component C by bringing a probe into contact with the component C. The presence or absence of the component C at the pickup position PP is detected based on the detection data of the component presence sensor 93. The detection data of the component presence sensor 93 is transmitted to the component mounting apparatus 1. The component mounting apparatus 1 controls the suction timing of the component C by the suction nozzle 4 based on the detection data of the component presence sensor 93.

< fraction 1 > of sorting

As shown in fig. 4 and 5, the 1 st sorting unit 60 is disposed between the 4 th position P4 and the pickup position PP. The 1 st sorting unit 60 is excited by the vibrator 33. As shown in fig. 5, the 1 st sorting unit 60 includes a partition member 61 disposed above the conveying member 29. The partition member 61 is fixed to at least a part of the main frame 11.

The 1 st sorting unit 60 passes only the components C in the 1 st predetermined state one by one. The predetermined state of the component C includes a predetermined posture of the component C. The 1 st sorting unit 60 passes only the components C in the 1 st posture one by one.

In the present embodiment, the 1 st posture of the component C is a posture in which the dimension of the component C in the Z-axis direction (vertical direction) is the smallest. In the present embodiment, the 1 st posture of the component C is a posture in which the upper surface 29S of the conveying member 29 contacts the 2 nd side surface Dd of the body D. The partition member 61 is separated upward by a predetermined amount from the upper surface 29S of the conveying member 29 so that only the member C in the 1 st posture passes through.

Fig. 7A, 7B, 7C, and 7D are schematic diagrams for explaining the operation of the 1 st sorting unit 60 according to the present embodiment. As shown in fig. 7A, in the 1 st posture in which the upper surface 29S of the conveying member 29 is in contact with the 2 nd side surface Dd of the body D, the member C can pass below the partition member 61.

As shown in fig. 7B, in a state where the upper surface 29S of the conveying member 29 is in contact with the 1 st side surface Dc of the main body D, the main body D is hooked on the partition member 61, and the member C cannot pass below the partition member 61.

As shown in fig. 7C, in a state where the upper surface 29S of the conveying member 29 is in contact with the upper surface Da of the main body D, the lead E is caught by the partition member 61, and the member C cannot pass below the partition member 61.

As shown in fig. 7D, even if the component C is in the 1 st posture, when the components C are conveyed in a superimposed state, the upper component C is caught by the partition member 61, and the upper component C cannot pass below the partition member 61.

In this way, the 1 st sorting unit 60 passes only the components C in the 1 st posture one by one. The member C hooked on the partition member 61 falls from the 1 st sorting unit 60. That is, the 1 st sorting unit 60 causes the component C not in the 1 st predetermined state to fall from the 1 st sorting unit 60.

In the present embodiment, the 1 st sorting unit 60 causes the component C not in the 1 st predetermined state to fall from the 1 st sorting unit 60 to the 1 st belt 21. In the Y-axis direction, the position of the 1 st sorting part 60 is the same as the position of at least a part of the slope part 211 of the 1 st belt 21. The height of the slope portion 211 is lower than the height of the 2 nd belt 22 and the conveying member 29. The 1 st sorting unit 60 drops the component C not in the 1 st posture to the slope portion 211.

The component C dropped onto the slope portion 211 of the 1 st belt 21 is conveyed to the 2 nd position P2 by the 1 st belt 21, and then conveyed to the 1 st sorting portion 60 again by the 2 nd belt 22.

The 1 st sorting unit 60 may drop the component C not in the 1 st predetermined state toward the slope component 40.

The position of the partition member 61 in the Z-axis direction can be adjusted. The distance between the partition member 61 and the upper surface 29S of the conveying member 29 is adjusted based on the outer shape and the size of the component C so that only the component C in the 1 st posture passes through.

< 2 nd sorting section >

As shown in fig. 4 and 6, the 2 nd sorting unit 70 is disposed between the 1 st sorting unit 60 and the pickup position PP. The 2 nd sorting unit 70 is excited by the vibrator 33. As shown in fig. 6, the 2 nd sorting unit 70 has a guide member 71 disposed on the left side (-X side) of the conveying surface 31 of the 2 nd conveying member 32B. The 2 nd conveying member 32B has a slope surface 74 disposed on the + X side of the conveying surface 31 of the 2 nd conveying member 32B. The slope surface 74 is disposed below the conveying surface 31 of the 2 nd conveying member 32B. The slope surface 74 slopes downward toward the + X direction.

The component C having passed through the 1 st sorting section 60 is conveyed to the 1 st conveying member 32A, and then conveyed to the 2 nd conveying member 32B of the 2 nd sorting section 70. The component C conveyed to the 1 st conveying component 32A is supplied to the 2 nd conveying component 32B while being guided by the guide component 35.

The guide member 71 guides the member C supplied from the 1 st conveying member 32A and conveyed to the 2 nd conveying member 32B forward. The guide member 71 is disposed on the left side (-X side) of the conveyance surface 31 of the 2 nd conveyance member 32B. The component C conveyed to the 2 nd conveying member 32B is restrained from falling from the 2 nd conveying member 32B to the-X side by the guide member 71.

The dimension of the conveying surface 31 of the 2 nd conveying member 32B in the X axis direction is smaller than the dimension of the conveying surface 31 of the 1 st conveying member 32A in the X axis direction.

The 2 nd sorting unit 70 passes only the component C in the 1 st predetermined state and the 2 nd predetermined state. The predetermined state of the component C includes a predetermined posture of the component C. The 2 nd sorting unit 70 passes only the component C in the 1 st posture and the 2 nd posture.

In the present embodiment, the 1 st posture of the component C is a posture in which the lead E protrudes from the body D in a predetermined direction. In the present embodiment, the 2 nd posture of the component C is a posture in which the lead E protrudes from the body D in the + X direction. The dimension of the conveying surface 31 of the 2 nd conveying member 32B in the X axis direction is determined such that only the member C in the 2 nd posture passes through.

Fig. 8A, 8B, and 8C are schematic diagrams for explaining the operation of the 2 nd sorting unit 70 according to the present embodiment. As shown in fig. 8A, in the 2 nd posture in which the upper surface Da of the main body D faces the guide member 71 and the lead E protrudes from the main body D in the + X direction, the component C can pass through the 2 nd conveyance member 32B.

As shown in fig. 8B, the component C cannot pass through the 2 nd feeding member 32B in a state where the lead E protrudes from the body D in the + Y direction or the-Y direction. That is, in a state where the lead E protrudes from the body D in the + Y direction or the-Y direction, the dimension of the conveyance surface 31 of the 2 nd conveyance member 32B in the X axis direction is sufficiently smaller than the dimension of the body D in the X axis direction, and therefore, the contact area between the body D and the conveyance surface 31 in the state shown in fig. 8B is smaller than the contact area between the body D and the conveyance surface 31 when the member C is in the 2 nd posture. When the contact area between the body D and the conveying surface 31 is small, the component C falls from the conveying surface 31 to the + X side due to the action of gravity.

As shown in fig. 8C, even in a state where the lead E protrudes from the body D in the-X direction, the component C cannot pass through the second feeding member 32B. That is, even in a state where the lead E protrudes from the body D in the-X direction, the contact area between the body D and the conveying surface 31 is smaller than the contact area between the body D and the conveying surface 31 when the component C is in the 2 nd posture. When the contact area between the body D and the conveying surface 31 is small, the component C falls from the conveying surface 31 to the + X side due to the action of gravity.

In this way, the 2 nd sorting unit 70 passes only the component C in the 2 nd posture. The component C that cannot pass through the 2 nd conveyance component 32B falls from the 2 nd sorting unit 70. That is, the 2 nd sorting unit 70 drops the component C not in the 2 nd predetermined state from the 2 nd sorting unit 70.

In the present embodiment, the 2 nd sorting unit 70 drops the component C not in the 2 nd predetermined state from the 2 nd sorting unit 70 to the slope component 40. The position of the 2 nd sorting portion 70 is the same as the position of at least a part of the slope member 40 in the Y-axis direction. The 2 nd sorting unit 70 drops the component C not in the 2 nd posture toward the slope component 40.

The component C dropped on the slope component 40 is conveyed to the 2 nd position P2 by the 1 st belt 21, and then conveyed to the 1 st sorting section 60 again by the 2 nd belt 22.

The 2 nd sorting unit 70 may drop the component C not in the 2 nd predetermined state onto the slope portion 211 of the 1 st belt 21.

The dimension of the conveying surface 31 of the 2 nd conveying member 32B in the X axis direction can be adjusted. The dimension of the conveying surface 31 of the 2 nd conveying member 32B in the X axis direction can be adjusted by adjusting the position of the guide member 71 in the X axis direction, for example. The dimension of the conveying surface 31 of the 2 nd conveying member 32B in the X axis direction is adjusted based on the outer shape and the dimension of the component C so that only the component C in the 2 nd posture passes through.

< Direction setting part >

Fig. 9 is a plan view showing the direction setting portion 80 of the present embodiment. Fig. 10 is a sectional view showing a direction setting part 80 of the present embodiment. As shown in fig. 4, 6, 9, and 10, the direction setting section 80 is disposed between the 2 nd sorting section 70 and the pickup position PP. The direction setting unit 80 adjusts the component C in the 2 nd posture having passed through the 2 nd sorting unit 70 to the 3 rd posture.

The direction setting section 80 includes: a guide member 81 disposed on the right side (+ X side) of the conveying surface 31 of the 3 rd conveying member 32C; a guide member 82 disposed on the left side (-X side) of the conveying surface 31 of the 3 rd conveying member 32C; a guide member 83 disposed in front of the guide member 81; a guide member 84 disposed in front of the guide member 83; a guide member 85 disposed in front of the guide member 82; and a posture adjusting member 86 supported by the guide member 85. The 3 rd conveying member 32C, the guide member 81, the guide member 82, the guide member 83, the guide member 84, the guide member 85, and the posture adjustment member 86 vibrate by driving of the vibrator 33.

The

guide members

81 and 82 guide the members C passing through the 2 nd sorting unit 70 forward. The guide surface 81G of the guide member 81 faces the guide surface 82G of the guide member 82. The guide surface 81G is parallel to the guide surface 82G. The guide surface 81G and the guide surface 82G are parallel to the YZ plane.

The guide member 83, the guide member 84, and the guide member 85 guide the member C passing between the guide member 81 and the guide member 82 forward. The guide surface 85G of the guide member 85 faces the guide surface 83G of the guide member 83 and the guide surface 84G of the guide member 84, respectively. The guide surface 83G is inclined so as to approach the guide surface 85G forward. The guide surface 84G is parallel to the guide surface 85G.

Guide surfaces

84G and 85G are parallel to the YZ plane, respectively. The position of the front end of guide surface 81G is substantially the same as the position of the rear end of guide surface 83G in the Y-axis direction. The position of the front end of guide surface 83G is substantially the same as the position of the rear end of guide surface 84G in the Y-axis direction. The distance between the guide surface 84G and the guide surface 85G is shorter than the distance between the guide surface 81G and the guide surface 82G.

The posture adjusting means 86 adjusts the component C in the 2 nd posture to the 3 rd posture. The 3 rd posture is a posture in which the lead E protrudes downward from the body D. The posture adjustment member 86 is fixed to the guide surface 85G of the guide member 85. The posture adjustment member 86 has a slope portion 86A and a flat portion 86B disposed forward of the slope portion 86A. The slope portion 86A is inclined upward toward the front. The front end of the slope portion 86A is connected to the rear end of the flat portion 86B.

As shown in fig. 9, the component C from the 2 nd sorting unit 70 passes between the guide surface 81G and the guide surface 82G while maintaining the 2 nd posture. The main body D of the component C passing between the guide surface 81G and the guide surface 82G is in contact with the slope portion 86A. When the main body D moves forward while being in contact with the slope portion 86A, the main body D gradually rises. Further, in a state where the main body D moves forward while contacting the slope portion 86A, the leading end portion of the lead E is guided by the guide surface 83G. The body D is guided by the slope portion 86A, the lead E is guided by the guide surface 83G, and the component C moves forward, whereby the posture of the component C changes from the 2 nd posture to the 3 rd posture. The component C adjusted to the 3 rd posture moves between the flat portion 86B and the guide surface 84G while maintaining the 3 rd posture, and reaches the pickup position PP. Thereby, as shown in fig. 9 and 10, the component C in the 3 rd posture is disposed at the pickup position PP. The mounting head 5 can hold the upper surface Da of the main body D with the suction nozzle 4 at the pickup position PP.

[ Effect ]

As described above, according to the present embodiment, the feeder 10 includes: a 1 st belt 21 for conveying the component C supplied to the 1 st position P1 in the-Y direction and supplying the component C to the 2 nd position P2; a return guide member 23 that guides the component C supplied to the 2 nd position P2 to the 3 rd position P3 adjacent to the 2 nd position P2; a 2 nd belt 22 for conveying the component C supplied to the 3 rd position P3 in the + Y direction and supplying the component C to the 4 th position P4; and a conveying member 29 and a conveying member 32 for vibrating the conveying surface 31 with which the component C is in contact and supplying the component C supplied to the 4 th position P4 to the pickup position PP of the mounting head 5. The conveying paths of the plurality of parts C are ensured by the 1 st conveyor belt 21, the 2 nd conveyor belt 22, the conveying section 29, and the conveying section 32. The 1 st belt 21 and the 2 nd belt 22 are arranged in the X-axis direction, and the 2 nd belt 22 and the conveying member 32 are arranged in the Y-axis direction, thereby suppressing an increase in the size of the feeder 10 in each of the X-axis direction and the Y-axis direction. By suppressing the size of the feeder 10 (the width of the feeder 10) in the X-axis direction, the number of feeders 10 that can be mounted on the feeder storage portion 8 can be increased. By suppressing the reduction in the number of feeders 10 that can be mounted on feeder housing 8, it is possible to suppress the reduction in the types of components C when scattered components C are supplied to component mounting apparatus 1. Further, the component C can be conveyed to the pickup position PP by the conveying member 29 and the conveying member 32 by a conveying method equivalent to that of the bowl feeder.

The conveying speed of the component C by the 1 st belt 21 is lower than the conveying speed of the component C by the 2 nd belt 22. This allows the scattered components C to be smoothly transferred from the 1 st belt 21 to the 2 nd belt 22.

The height of the 1 st tape 21 at the 2 nd position P2 is the same as or higher than the height of the 2 nd tape 22 at the 3 rd position P3 than the height of the 2 nd tape 22 at the 3 rd position P3. This allows the scattered components C to be smoothly transferred from the 1 st belt 21 to the 2 nd belt 22.

A sorting unit 50 for passing only the component C in a predetermined state is provided between the 3 rd position P3 and the pickup position PP. By the sorting unit 50, the feeder 10 can feed only the component C in a predetermined state to the pickup position PP.

The sorting section 50 drops the component C that is not in the predetermined state from the sorting section 50. This suppresses the component C not in the predetermined state from being supplied to the pickup position PP. The component C not in the predetermined state is dropped from the sorting section 50 to at least one of the slope component 40 and the 1 st belt 21, and the component C thus dropped is conveyed to the sorting section 50 again.

The predetermined state of the component C includes a predetermined posture of the component C. The predetermined postures of the component C include the 1 st posture and the 2 nd posture. The sorting unit 50 includes: a 1 st sorting unit 60 for passing only the components C in the 1 st posture one by one; and a 2 nd sorting unit 70 for passing only the component C in the 2 nd posture. By providing the 1 st sorting unit 60 and the 2 nd sorting unit 70 as the sorting unit 50, the sorting unit 50 can pass the component C in the 1 st posture and the 2 nd posture while suppressing complication of the configuration of the 1 st sorting unit 60 and the 2 nd sorting unit 70.

In the present embodiment, the member C has a body D and a lead E protruding from the body D. The 1 st posture of the component C includes a posture in which the vertical dimension of the component C is the smallest. The 2 nd posture of the component C includes a posture in which the lead E protrudes from the body D in the + X direction, which is a predetermined direction. Thus, even when the component C has the lead E, the sorting unit 50 can pass the component C in the 1 st posture and the 2 nd posture.

The 1 st sorting unit 60 drops the component C not in the 1 st posture onto the slope portion 211 of the 1 st belt 21. This enables the 1 st belt 21 to smoothly convey the component C dropped from the 1 st sorting unit 60.

A direction setting part 80 for adjusting the component C passing through the sorting part 50 to the 3 rd posture is provided. Thereby, the component C in the 3 rd posture is supplied to the pickup position PP.

The 3 rd posture of the component C includes a posture in which the lead E protrudes downward from the body D. Thereby, the mounting head 5 can hold the upper surface Da of the main body D with the suction nozzle 4 at the pickup position PP.
