[0011] Hereinafter, an embodiment will be described with reference to the drawings.

[0012] (Embodiment) First, with reference to FIG. 1, a component mounting system according to an embodiment of the present invention will be described.

[0013] FIG. 1 is a schematic plan view of a component mounting system 1 according to an embodiment.

[0014] The component mounting system 1 shown in FIG. 1 is a device that mounts and mounts a leaded component 2 having two leads on a substrate 3. The component 2 is, for example, a radial connector component. The substrate 3 on which the component 2 is mounted becomes a "component mounting substrate." In FIG. 1, the component 2 is illustrated only in an exemplary location.

[0015] The component mounting system 1 includes a board holding table 4, a mounting unit 6, a pallet system 8, a pallet driving section 10, a first component supply section 12, a second component supply section 14, and a control section 16.

[0016] The substrate holding table 4 is a table that positions and holds the substrate 3 on its upper surface. The substrate holding table 4 in this embodiment is movable in the horizontal direction.

[0017] The mounting unit 6 is a unit that mounts components 2 on a board 3 that has been positioned by the board holding table 4. The configuration of the component mounting system 1 excluding the mounting unit 6 is referred to as a component supply system 11. The mounting unit 6 of this embodiment includes a transfer head 20 and an insertion head 22.

[0018] The transfer head 20 and the insertion head 22 are each members having a pair of opening and closing claws that can hold the component 2. The transfer head 20 is a head that transfers the component 2 held by the pallet system 8 to the insertion head 22. The insertion head 22 is a head that inserts the component 2 transferred from the transfer head 20 into the board 3 for mounting.

[0019] The pallet system 8 is a component holding system that holds components 2. The pallet system 8 has a plurality of pallets 9, and each pallet 9 can hold one component 2. The plurality of pallets 9 are connected endlessly, and are driven by a pallet drive unit 10 in a rotation direction X1, which is, for example, the forward direction.

[0020] The pallet driving unit 10 in this embodiment is a plurality of pulleys provided inside the plurality of pallets 9. The pallet driving unit 10 is driven by a servo motor (not shown) and can be rotated in both a forward rotation direction and a reverse rotation direction.

[0021] The first component supply unit 12 and the second component supply unit 14 are members that each supply components 2 to a pallet 9 of the pallet system 8. The first component supply unit 12 of this embodiment is a tape feeder device that supplies radially taped components 2A as the components 2. The second component supply unit 14 of this embodiment is a bowl feeder device that supplies loose components 2B, which will be described later, as the components 2.

[0022] The second component supply unit 14 includes a component supply path 24, a transfer device 26, and a bowl feeder .

[0023] The component supply path 24 is a member that forms a path for supplying the bulk components 2B to the pallet system 8. The transfer device 26 is a device that transfers the bulk components 2B supplied from the component supply path 24 onto a pallet 9 of the pallet system 8. The bowl feeder 28 is a feeder that supplies the bulk components 2B through the component supply path 24.

[0024] The second component supply unit 14 may also be called a "bulk component supply unit."

[0025] The control unit 16 is a member that controls various components of the component mounting system 1. The control unit 16 is configured to have, for example, a microcomputer. The control unit 16 is electrically connected to each of the components that make up the component mounting system 1.

[0026] In the component mounting system 1 of this embodiment, the control unit 16 synchronizes the rotation of the pallet 9 by the pallet system 8 with the transfer operation of the bulk components 2B by the transfer device 26. This allows the bulk components 2B supplied from the bowl feeder 28 to be supplied to the pallet 9 with high accuracy, even when the pallet 9 rotates at high speed, thereby improving the supply efficiency of the bulk components 2B. The configuration of the component supply system 11, which includes the pallet system 8 and the second component supply unit 14, will be described below with reference to Figure 2 and subsequent drawings.

[0027] 2 and 3 are perspective views showing the connection points between the pallet system 8 and the second component supply unit 14. FIG.

[0028] As shown in Figures 2 and 3, the transfer device 26 of the second component supply unit 14 is composed of a link mechanism that combines multiple plates and multiple arms. As shown in Figure 3, the transfer device 26 has a cam plate 30, which is driven in the front-to-rear direction (arrow A1) by an actuator (not shown). The cam plate 30 is connected to a first link plate 32 and a second link plate 33 via an arm, and drives the first link plate 32 and the second link plate 33 in the front-to-rear direction, respectively (arrows A2 and A3). The movement directions of the link plates 32 and 33 are not always the same, and they may move in different directions depending on the movement direction and position of the cam plate 30. This will be described in more detail later.

[0029] The first link plate 32 is connected to a chuck member 34 (FIG. 4) for gripping the bulk part 2B.

[0030] 4 is a perspective view showing the peripheral configuration of the chuck member 34 connected to the first link plate 32. The chuck member 34 is a member for gripping the loose parts 2B, and is fixed to the first link plate 32, and moves back and forth integrally with the first link plate 32 as it moves back and forth (arrow A2).

[0031] The chuck member 34 has a fixed portion 36 and a movable portion 38. The fixed portion 36 is fixed to the first link plate 32, and the movable portion 38 is attached so as to be rotatable relative to the fixed portion 36 (arrow R1). The fixed portion 36 has a gripping portion 40 at its tip, and the movable portion 38 also has a gripping portion 42 at its tip. The two gripping portions 40, 42 can sandwich and grip the loose part 2B (not shown), and the movable portion 38 can release the grip of the loose part 2B by rotating relative to it. Figure 4 shows the gripping portion 42 separated from the gripping portion 40.

[0032] Returning to FIG. 2, a cam member 44 is fixed to the second link plate 33. The cam member 44 is a member that moves back and forth integrally with the second link plate 33 (arrow A3). An opening / closing member 46 that serves as a cam follower is connected to the cam member 44. The opening / closing member 46 is a member that controls the opening and closing of the chuck member 34 described above. Here, the operation of the opening / closing member 46 will be described with reference to FIGS. 5A to 6B.

[0033] 5A to 6B are perspective views illustrating the opening and closing of chuck member 34 by open / close member 46. Figs. 5A and 5B show a state in which chuck member 34 is closed, and Figs. 6A and 6B show a state in which chuck member 34 is open.

[0034] As shown in FIG. 5A, when the cam member 44 advances toward the pallet system 8 together with the second link plate 33 (not shown) (arrow A4), one end of the opening / closing member 46 moves along a groove 45 formed in the cam member 44, causing the opening / closing member 46 to rotate (arrow R2). As shown in FIG. 5B, a biasing member 48 is provided on the chuck member 34, and the biasing member 48 constantly biases the movable part 38 in the closing direction (arrow R3). As the opening / closing member 46 rotates outward (arrow R2), the biasing force of the biasing member 48 causes the movable part 38 to rotate in the closing direction (arrow R3). This controls the chuck member 34 to a closed state, allowing the gripping portions 40 and 42 to clamp and grip the loose part 2B.

[0035] As shown in Fig. 6A, when the cam member 44 retracts in a direction away from the pallet system 8 (arrow A5), one end of the opening / closing member 46 moves along the groove 45 of the cam member 44, causing the opening / closing member 46 to rotate (arrow R4). As shown in Fig. 6B, the opening / closing member 46 presses against the upper part of the movable part 38, causing the opening / closing member 46 to rotate in the opening direction against the biasing force of the biasing member 48 (arrow R5). This causes the gripping part 42 to move in a direction away from the gripping part 40, and the chuck member 34 is controlled to the open state. The gripping of the loose part 2B by the gripping parts 40 and 42 can be released, and a new loose part 2B can be gripped.

[0036] The cam follower 50 moves in conjunction with the forward and backward movement of the cam member 44 and the second link plate 33. The cam follower 50 is a member connected to the second link plate 33, and moves in the forward and backward direction integrally with the second link plate 33 and the cam member 44 (arrows A6, A7).

[0037] As shown in Fig. 5A, when the cam member 44 advances (arrow A4), the cam follower 50 also advances in the same direction (arrow A6) and engages with the pallet claws 52 of the pallet 9. As shown in Fig. 6A, when the cam member 44 and the second link plate 33 retreat (arrow A5), the cam follower 50 also retreats in the same direction (arrow A7) and is disengaged from the pallet claws 52.

[0038] The engagement relationship between the cam follower 50 and the pallet claw 52 will be explained using Figures 7 and 8. Figure 7 is a perspective view from below of the cam follower 50 not engaged with the pallet claw 52, ​​and Figure 8 is a perspective view from below of the cam follower 50 engaged with the pallet claw 52.

[0039] As shown in Figure 7, the pallet claws 52 are a pair of members arranged to sandwich the bulk parts 2B, and one side is biased in the closing direction by a biasing member (not shown) (arrow A8). When the cam followers 50 are retracted (arrow A7), the pallet claws 52 are controlled to a closed state by the biasing member. When the pallet claws 52 are controlled to a closed state, they can grip and hold the bulk parts 2B when they are placed inside.

[0040] 8, when the cam follower 50 moves forward (arrow A6) and engages with the pallet claw 52, ​​the cam follower 50 presses the pallet claw 52 in the opening direction against the biasing force of the biasing member (arrow A9). This controls the pallet claw 52 to an open state, making it possible to place new loose parts 2B inside the pallet claw 52.

[0041] Next, the reciprocating movement of the chuck member 34 will be described with reference to FIGS.

[0042] 9 and 10 are side views for explaining the reciprocating movement of the chuck member 34. FIG.

[0043] 9, a first arm 54 is provided between the cam plate 30 and the first link plate 32. The first arm 54 is an arm-shaped member that connects the cam plate 30 and the first link plate 32, and one end 56 of the first arm 54 is disposed in a cam groove 58 of the cam plate 30. The cam groove 58 extends in the horizontal direction and is divided into two areas, an upper and a lower area.

[0044] 9, when the cam plate 30 advances toward the pallet 9 of the pallet system 8 (arrow A10), one end 56 of the first arm 54 is positioned in the lower region on the right side of the cam groove 58, and the first arm 54 rotates clockwise on the page (arrow R6). As a result, the first link plate 32 connected to the first arm 54 retreats in a direction away from the pallet 9 (arrow A11).

[0045] 10, when cam plate 30 moves backward in a direction away from pallet 9 (arrow A12), one end 56 of first arm 54 is positioned in the upper region on the left side of cam groove 58, and first arm 54 rotates counterclockwise (arrow R7). As a result, first link plate 32 connected to first arm 54 moves forward in a direction approaching pallet 9 (arrow A13).

[0046] 9 and 10, the first link plate 32 is moved in the front-rear direction in response to the front-rear movement of the cam plate 30, thereby driving the chuck member 34 attached to the first link plate 32 in the front-rear direction. The movement direction of the cam plate 30 and the movement direction of the chuck member 34 are opposite directions.

[0047] 9, when the chuck member 34 is retracted from the pallet 9, the chuck member 34 is located at a pickup position P1 where it can pick up a bulk part 2B located at the end of the part supply path 24. When the chuck member 34 is close to the pallet 9 as shown in FIG. 10, the chuck member 34 is located at a delivery position P2 where it can deliver the held bulk part 2B to the pallet 9.

[0048] 9 and 10, a shutter device is provided that operates to control the supply of loose components 2B in the component supply path 24 in accordance with the reciprocating movement of the chuck member 34. The shutter device will be described with reference to FIG.

[0049] Fig. 11 is a cross-sectional view showing the vicinity of the pickup position P1 and the delivery position P2. Fig. 11 is a view of a cross section at a height position including the body of the bulk part 2B as seen from above.

[0050] 11, a shutter device 60 is provided near the pickup position P1. The shutter device 60 is a device for controlling the supply of loose components 2B in the component supply path 24.

[0051] The shutter device 60 has a first end 60A and a second end 60B. The first end 60A is located downstream in the supply direction of the loose parts 2B (arrow A14), and the second end 60B is located upstream in the supply direction of the loose parts 2B (arrow A15). As the shutter device 60 swings, the first end 60A and the second end 60B move together. The first end 60A functions as a stopper for the loose parts 2B located at the pickup position P1.

[0052] A biasing member 62 is attached to the shutter device 60. The biasing member 62 constantly biases the shutter device 60 counterclockwise in the drawing (arrow R8). The biasing force of the biasing member 62 moves the first end 60A of the shutter device 60 away from the component supply path 24, and the second end 60B stops at a position where it abuts against the side of the bulk component 2B. In this state, as shown in FIG. 11, the first end 60A does not block the supply of the bulk component 2B, and the bulk component 2B at the pickup position P1 can be supplied toward the pallet 9 (arrow A14). At the same time, the second end 60B abuts against the side of the next bulk component 2B at the pickup position P1, thereby blocking the advance of that bulk component 2B.

[0053] The opening and closing operation of the shutter device 60 is controlled by the gripping portion 40 of the chuck member 34. The opening and closing operation of the shutter device 60 will be described with reference to FIGS.

[0054] 12 and 13 are schematic plan views for explaining the opening and closing operation of the shutter device 60. FIG.

[0055] 12 and 13, the gripping portion 40 has an inclined surface 41 at a position facing the shutter device 60. The inclined surface 41 is configured to come into contact with the engaging portion 64 of the shutter device 60 as the gripping portion 40 moves back and forth.

[0056] 12, when the gripping portion 40 moves forward and away from the pickup position P1, the gripping portion 40 does not come into contact with the engaging portion 64 of the shutter device 60. In this case, the shutter device 60 is biased by the biasing member 62 (FIG. 11) described above to rotate (arrow R8) toward a position that allows the supply of loose parts 2B.

[0057] 13, when the gripping portion 40 retreats and reaches the pickup position P1, the inclined surface 41 of the gripping portion 40 comes into contact with the engaging portion 64 of the shutter device 60. As the engaging portion 64 is pressed by the inclined surface 41 (arrow A16), the shutter device 60 rotates clockwise around the rotation center 66 (arrow R9) against the biasing force of the biasing member 62. As a result, the first end 60A of the shutter device 60 moves to a position where it mechanically blocks the supply of loose parts 2B, and the supply of loose parts 2B is stopped.

[0058] As shown in Figures 12 and 13, the opening and closing operation of the shutter device 60 is controlled in accordance with the reciprocating movement of the chuck member 34. As shown in Figure 13, when the gripping portion 40 of the chuck member 34 is at the pickup position P1, the supply of loose parts 2B is stopped, and when the gripping portion 40 moves away from the pickup position P1, the supply of loose parts 2B is enabled. This allows the supply of loose parts 2B to be switched between enabled and disabled at the desired timing. The gripping portion 40 functions as a "cam" for controlling the opening and closing operation of the shutter device 60. The gripping portion 40 and the first end 60A of the shutter device 60 are located at different heights, so the first end 60A does not interfere with the gripping portion 40 as it moves back and forth.

[0059] Furthermore, the first end 60A moves between a position where it blocks the advance of the leading loose component 2B in the component supply path 24 (FIG. 13) and a position where it does not block the advance (FIG. 12) in conjunction with the reciprocating movement of the chuck member 34. The second end 60B moves between a position where it contacts the side of the next leading loose component 2B in the component supply path 24 to block the advance (FIG. 12) and a position where it does not contact the side (FIG. 13) in conjunction with the reciprocating movement of the chuck member 34. By swinging the shutter device 60 in this manner, the desired stopper function can be achieved.

[0060] 9 and 10, a second arm 68, separate from the first arm 54, is connected to the cam plate 30. The second arm 68 is an arm-shaped member for connecting the cam plate 30 and the second link plate 33 (FIG. 2). A third link plate 70 is connected to the second arm 68, and the third link plate 70 is connected to the second link plate 33. The cam plate 30 and the second link plate 33 are connected via the second arm 68 and the third link plate 70.

[0061] One end 72 of second arm 68 comes into contact with an uneven portion 74 formed on the upper surface of cam plate 30. As cam plate 30 moves back and forth (arrows A10, A12), one end 72 of second arm 68 moves along uneven portion 74. As second arm 68 and third link plate 70 rotate according to the shape of uneven portion 74, second link plate 33 connected to third link plate 70 moves in the front-to-rear direction. The front-to-rear movement of second link plate 33 will be described in detail below.

[0062] The operation of the second component supply unit 14 having the configuration shown in FIGS. 2 to 13 will be described with reference to FIGS. 14A to 17B.

[0063] 14A to 17B are side views illustrating the operation of the second component supply unit 14. FIGS. 14A and 14B correspond to a first state, 15A and 15B correspond to a second state, 16A and 16B correspond to a third state, and 17A and 17B correspond to a fourth state which is the same as the first state. FIGS. 14A, 15A, 16A, and 17A are each side views of the side where the cam plate 30 and first link plate 32 are exposed, and FIGS. 14B, 15B, 16B, and 17B are each side views of the side where the second link plate 33 is exposed.

[0064] As shown in FIGS. 14A and 14B, when the cam plate 30 advances to a position closest to the pallet 9 of the pallet system 8 (arrow A16), the first link plate 32 connected to the first arm 54 retracts (arrow A17) as the first arm 54 rotates (arrow R10), and the chuck member 34 is located at the pickup position P1. In response to the retraction of the chuck member 34, the shutter device 60 is controlled to the closed state, as shown in FIG. 13. Meanwhile, one end 72 of the second arm 68 is positioned in a recess in the concave-convex portion 74 of the cam plate 30, and the third link plate 70 connected to the second arm 68 rotates outward (arrow R11). As a result, the second link plate 33 and the cam member 44 connected to the third link plate 70 retract (arrow A18). As the second link plate 33 and the cam member 44 retract, the chuck member 34 is controlled to the open state, and the pallet jaws 52 are controlled to the closed state, as shown in FIGS. 6A and 6B.

[0065] As shown in FIGS. 15A and 15B, when cam plate 30 retreats (arrow A19) away from pallet 9 from the first state shown in FIGS. 14A and 14B, first link plate 32 and chuck member 34 connected to first arm 54 advance (arrow A20) as first arm 54 rotates (arrow R12). Chuck member 34 is positioned at transfer position P2. As chuck member 34 advances, shutter device 60 is controlled to the open state as shown in FIG. 12. As shown in FIG. 15A, one end 56 of first arm 54 is positioned at the middle position of cam groove 58 of cam plate 30. Meanwhile, one end 72 of second arm 68 is positioned at the convex portion of concave-convex portion 74, and third link plate 70 connected to second arm 68 rotates inward (arrow R13). As a result, second link plate 33 and cam member 44 connected to third link plate 70 advance (arrow A21). As the second link plate 33 and the cam member 44 move forward, the chuck member 34 is controlled to a closed state and the pallet claws 52 are controlled to an open state, as shown in FIGS. 5A and 5B.

[0066] The chuck member 34, controlled to the closed state, grips the bulk parts 2B at the pickup position P1 and advances from the pickup position P1 to the delivery position P2. The shutter device 60 is controlled to the open state, so the chuck member 34 can advance while gripping the bulk parts 2B. The pallet claws 52 are controlled to the open state, so the bulk parts 2B gripped by the chuck member 34 that has reached the delivery position P2 are positioned inside the pallet claws 52, and the pallet claws 52 are ready to grip the bulk parts 2B.

[0067] As shown in FIGS. 16A and 16B, when cam plate 30 retreats (arrow A22) in a direction away from pallet 9 from the second state shown in FIGS. 15A and 15B, one end 56 of first arm 54 remains in the upper region of cam groove 58, so first arm 54 does not rotate, and first link plate 32 and chuck member 34 do not move in the front-to-rear direction. Meanwhile, one end 72 of second arm 68 moves from the convex portion to the concave portion of concave-convex portion 74, causing third link plate 70 connected to second arm 68 to rotate outward (arrow R14). As a result, second link plate 33 and cam member 44 connected to third link plate 70 retreat (arrow A23). As second link plate 33 and cam member 44 retreat, chuck member 34 is controlled to the open state and pallet jaws 52 are controlled to the closed state, as shown in FIGS. 6A and 6B. As a result, the chuck members 34 release the chucking of the bulk parts 2B, and the pallet claws 52 grip the bulk parts 2B. In this manner, the bulk parts 2B can be transferred from the chuck members 34 to the pallet claws 52.

[0068] 17A and 17B, when the cam plate 30 advances toward the pallet 9 (arrow A24), it returns to the first state shown in Figures 14A and 14B. That is, the chuck member 34 retreats, the shutter device 60 is controlled to the closed state, the chuck member 34 is controlled to the open state, and the pallet claws 52 are controlled to the closed state. The chuck member 34 controlled to the open state is ready to pick up the next loose part 2B at the pickup position P1, and the shutter device 60 controlled to the closed state prevents the next loose part 2B at the pickup position P1 from advancing forward or falling out.

[0069] 16A and 16B to the fourth state shown in Figures 17A and 17B, first arm 54 rotates as one end 56 moves to the lower region of cam groove 58 (arrow R15). Meanwhile, one end 72 of second arm 68 moves over the convex portion of uneven portion 74 to the concave portion, but third link plate 70 connected to second arm 68 is designed not to rotate due to the inclination angle of second arm 68, the shape of uneven portion 74, and the connection relationship between second arm 68 and third link plate 70, etc. As a result, second link plate 33 and cam member 44 do not move back and forth, and chuck member 34 is maintained in the open state and pallet jaws 52 are maintained in the closed state. Therefore, when the chuck member 34 retreats (arrow A25), the chuck member 34 retreats while remaining in the open state, and can retreat to the pickup position P1 without carrying back the loose parts 2B that have been transferred to the pallet 9, and the gripping state of the loose parts 2B by the pallet claws 52 is also maintained.

[0070] As the chuck members 34 retract, the control unit 16 drives the pallet system 8 to rotate the stopped pallet 9. This causes the pallet 9 that has received the loose parts 2B to be sent to the next stopping position, and the next pallet 9 is sent to a position opposite the second component supply unit 14. Note that the control unit 16 stops the rotation of the pallet 9 from the first state shown in Figures 14A and 14B until at least the chuck members 34 start to retract.

[0071] The control unit 16 controls the cam plate 30 to repeatedly move back and forth, thereby causing the second component supply unit 14 to repeatedly perform the operations shown in Figures 14A to 17B. This allows bulk components 2B to be intermittently supplied to the rotating pallet 9. The control unit 16 synchronizes the rotation of the pallet 9 by the pallet system 8 with the transfer operation of the bulk components 2B by the transfer device 26, so that the bulk components 2B can be transferred to the pallet 9 with high precision even when the pallet 9 is rotating at high speed, improving the efficiency of supplying the bulk components 2B.

[0072] As described above, the part supply system 11 of the embodiment includes a pallet system 8 that endlessly rotates a pallet 9 that can hold parts 2, a bowl feeder 28 that supplies loose parts 2B to the pallet system 8 through a part supply path 24, a transfer device 26 that transfers the loose parts 2B supplied from the part supply path 24 to the pallet 9 of the pallet system 8, and a control unit 16, and the control unit 16 synchronizes the rotation operation of the pallet 9 by the pallet system 8 and the transfer operation of the loose parts 2B by the transfer device 26.

[0073] With this configuration, by synchronizing the rotational movement of the pallet 9 with the transfer movement of the bulk parts 2B, the bulk parts 2B can be transferred to the pallet 9 with high accuracy even when the pallet 9 rotates at high speed, and the bulk parts 2B can be supplied efficiently.

[0074] Furthermore, in the component supply system 11 of the embodiment, the control unit 16 controls the transfer device 26 and the pallet system 8 to transfer the bulk components 2B to the pallet 9 whose rotation has stopped. With this configuration, the bulk components 2B can be transferred to the pallet 9 with high accuracy even when the pallet 9 is rotating at high speed.

[0075] Furthermore, in the component supply system 11 of the embodiment, the transfer device 26 has a chuck member 34 that reciprocates between a pickup position P1 that picks up the bulk components 2B supplied from the component supply path 24 and a delivery position P2 that delivers the picked-up bulk components 2B to the pallet 9. With this configuration, the bulk components 2B can be delivered to the pallet 9 using a simple structure.

[0076] Furthermore, in the component supply system 11 of the embodiment, the chuck member 34 is openable and closable, and the transfer device 26 further includes an open / close member 46 that engages with the chuck member 34 to control the opening and closing of the chuck member 34. With this configuration, the opening and closing of the chuck member 34 can be controlled using a simple structure.

[0077] Furthermore, in the component supply system 11 of this embodiment, the transfer device 26 further includes a biasing member 48 that biases the chuck member 34 toward the closed state, and the control unit 16 controls the opening / closing member 46 to press the chuck member 34, which is located at the delivery position P2, from the closed state toward the open state. With this configuration, the opening / closing member 46 changes the chuck member 34 from the closed state to the open state, allowing the loose components 2B to be delivered to the pallet 9 at the desired timing.

[0078] Moreover, the component supply system 11 of the embodiment further includes a shutter device 60 that controls the supply of bulk components 2B in the component supply path 24.

[0079] Furthermore, in the component supply system 11 of the embodiment, the transfer device 26 has a gripping portion 40 as a cam that is linked to the transfer operation of the bulk components 2B, and the shutter device 60 opens and closes by contact with the gripping portion 40. With this configuration, the opening and closing operation of the shutter device 60 can be linked to the movement operation of the bulk components 2B.

[0080] Furthermore, in the component supply system 11 of the embodiment, the shutter device 60 has a first end 60A, which moves alternately between a position where it blocks and a position where it does not block the progress of the leading bulk component 2B on the component supply path 24, in conjunction with the transfer operation of the bulk component 2B by the transfer device 26. With this configuration, the desired shutter function can be achieved using a simple configuration.

[0081] Furthermore, in the component supply system 11 of the embodiment, the shutter device 60 has a second end 60B located upstream of the first end 60A in the conveying direction X1, and the second end 60B moves alternately between a position where it abuts against the next bulk component 2B at the front of the component supply path 24 to prevent its advance and a position where it does not abut, in conjunction with the transfer operation of the bulk component 2B by the transfer device 26. With this configuration, the desired shutter function can be achieved using a simple configuration.

[0082] Moreover, the component mounting system 1 of the embodiment includes a component supply system 11 and a mounting unit 6 that mounts components 2 held on a pallet 9 of the component supply system 11 onto a board 3. With this configuration, it is possible to achieve the same effects as the component supply system 11 of the embodiment.

[0083] In addition, the part supply method of the embodiment includes the steps of using a pallet system 8 to endlessly rotate a pallet 9 capable of holding parts 2, using a part supply path 24 to supply loose parts 2B, and using a transfer device 26 to transfer the loose parts 2B supplied from the part supply path 24 to the pallet 9, and synchronizes the rotation operation of the pallet 9 by the pallet system 8 and the transfer operation of the loose parts 2B by the transfer device 26.

This method makes it possible to achieve the desired shutter function using a simple configuration.
