[0023] (Embodiment 1) Fig. 1 is a schematic perspective view of an example of a component supplying device 1 according to the first embodiment of the present disclosure. Fig. 2 is a schematic front view of the example of the component supplying device 1 according to the first embodiment of the present disclosure. Fig. 3 is a control block diagram of the example of the component supplying device 1 according to the first embodiment of the present disclosure. Note that the X, Y, and Z directions in the figure indicate the depth direction, width direction, and height direction of the component supplying device 1.

[0024] 1, the component supplying device 1 includes a main body section 2, a component alignment section 3, a mixing section 4, and a cassette holding section 5. The component supplying device 1 also includes a component conveying path 6, a mixing air supply path 7, and a conveying air supply path 8.

[0025] In the example shown in Figure 1, the component supplying device 1 includes a component conveying tube 9 that constitutes part of the component conveying path 6, an agitating air supply tube 10 that constitutes part of the agitating air supply path 7, and a conveying air supply tube 11 that constitutes part of the conveying air supply path 8.

[0026] 1, a component storage cassette 12 is attached to the cassette holding unit 5. Furthermore, a notification lamp 13 is disposed on the side surface of the mixing unit 4.

[0027] The component supplying device 1 mixes the multiple components stored in the component storage cassette 12 in the mixing section 4, and aligns the multiple components in a line in the component alignment section 3. The component supplying device 1 transports the multiple components aligned in a line to a component supplying position P1 via a component transport path 6. The component supplying position P1 is a position where a component supplying opening 2a is provided on the upper surface of the main body 2, and is a position where the components are picked up by a component mounting device 90. The components transported to the component supplying position P1 are picked up by the component mounting device 90 and mounted, for example, at a predetermined position on a board.

[0028] In the component supplying device 1, air is used to agitate and transport a plurality of components. The air used for agitation is supplied to the component alignment unit 3 via an agitating air supply path 7. The air used for transport is supplied to the component transport path 6 via a transport air supply path 8.

[0029] The component storage cassette 12 stores a plurality of components, each of which has the same size and shape.

[0030] Each of the components of the component supplying device 1 will now be described in detail.

[0031] <Main body> The main body 2 is the main body portion of the component supplying device 1. A component supply opening 2a is provided on the upper surface of the main body 2 at a position corresponding to a component supplying position P1 to which a plurality of components are transported. When a component is transported to the component supplying position P1, the component is exposed from the component supplying opening 2a. The component mounting device 90 picks up a component placed at the component supplying position P1 from the component supplying opening 2a of the main body 2.

[0032] The main body 2 has a mechanism for generating air for stirring and transporting. Specifically, as shown in Fig. 2, the main body 2 has a control unit 20, an air introduction path 21, a first stirring air supply path 22, a first transport air supply path 23, a stirring air control valve 24, a transport air control valve 25, an air suction path 26, and a suction air control valve 27.

[0033] The control unit 20 controls each component of the part supplying device 1. The control unit 20 can be realized by a semiconductor element or the like. For example, the control unit 20 can be realized by a control circuit. The control unit 20 can be configured by, for example, a microcomputer, a CPU, an MPU, a GPU, a DSP, an FPGA, or an ASIC. The functions of the control unit 20 may be configured by hardware alone, or may be realized by combining hardware and software. The control unit 20 realizes a predetermined function by reading data and programs stored in a storage unit such as a memory and performing various arithmetic processing.

[0034] 3, the control unit 20 has, as functional components, an agitation processing unit 28 and a component conveyance control unit 29. The agitation processing unit 28 controls the agitation air control valve 24. The component conveyance control unit 29 controls the conveyance air control valve 25 and the suction air control valve 27.

[0035] The air introduction path 21 introduces compressed air from an air introduction port 21a provided on the side surface on the rear end side of the main body 2. The air introduction path 21 branches into a first stirring air supply path 22 and a first conveying air supply path 23 inside the main body 2. For example, the air introduction path 21 is formed of piping. In addition, a pump that supplies compressed air may be connected to the air introduction port 21a.

[0036] The first agitation air supply path 22 is a flow path that supplies air to the component alignment unit 3. The first agitation air supply path 22 is connected to the agitation air supply tube 10, and constitutes a part of the agitation air supply path 7. For example, the first agitation air supply path 22 is constituted by piping. An agitation air control valve 24 is disposed in the first agitation air supply path 22.

[0037] The first conveying air supply path 23 is a flow path that supplies air to the part conveying path 6. The first conveying air supply path 23 is connected to the conveying air supply tube 11, and constitutes a part of the conveying air supply path 8. For example, the first conveying air supply path 23 is constituted by piping. A conveying air control valve 25 is disposed in the first conveying air supply path 23.

[0038] 2, the first conveying air supply path 23 is separated into two conveying air supply paths. The two conveying air supply paths are connected via a conveying air supply tube 11.

[0039] The agitation air control valve 24 controls the air flowing through the first agitation air supply path 22. For example, when the agitation air control valve 24 is opened, air is supplied to the component alignment unit 3 through the first agitation air supply path 22 and the agitation air supply tube 10. When the agitation air control valve 24 is closed, air is no longer supplied to the component alignment unit 3 through the first agitation air supply path 22 and the agitation air supply tube 10. The agitation air control valve 24 is controlled by the agitation processing unit 28 of the control unit 20.

[0040] The conveying air control valve 25 controls the air flowing through the first conveying air supply path 23. For example, when the conveying air control valve 25 is opened, air is supplied to the component conveying path 6 through the first conveying air supply path 23 and the conveying air supply tube 11. When the conveying air control valve 25 is closed, air is no longer supplied to the component conveying path 6 through the first conveying air supply path 23 and the conveying air supply tube 11. The conveying air control valve 25 is controlled by the component conveying control unit 29 of the control unit 20.

[0041] The air suction path 26 is a flow path that sucks in air. In the air suction path 26, air is sucked in from an air suction port 26a provided on a side surface of the main body 2. The air suction path 26 extends from the air suction port 26a to the component supply position P1. For example, the air suction path 26 is formed of a pipe. In addition, a pump that sucks in air may be connected to the air suction port 26a.

[0042] The component supplying device 1 can create a negative pressure by sucking air from the air suction path 26. This allows the component to be sucked in, assisting in the transport of the component to the component supplying position P1 and holding the component at the component supplying position P1.

[0043] A suction air control valve 27 is disposed in the air suction passage 26 .

[0044] The suction air control valve 27 controls the air flowing through the air suction path 26. For example, when the suction air control valve 27 opens, the air in the air suction path 26 is sucked in, creating a negative pressure. When the suction air control valve 27 closes, the air in the air suction path 26 is no longer sucked in. The suction air control valve 27 is controlled by the component conveyance control unit 29 of the control unit 20.

[0045] The agitation processing unit 28 and the component transport control unit 29 control the agitation air control valve 24 , the transport air control valve 25 and the suction air control valve 27 based on the detection result of the component detection sensor 14 .

[0046] Furthermore, the control unit 20 may control the notification lamp 13 based on the detection result of the part detection sensor 14. The part detection sensor 14 will be described later.

[0047] Next, the part alignment unit 3 and the mixing unit 4 will be described with reference to Fig. 4 to Fig. 6. Fig. 4 is a schematic cross-sectional view taken along line AA in Fig. 1. Fig. 5 is a schematic cross-sectional view taken along line BB in Fig. 2. Fig. 6 is a schematic cross-sectional view taken along line CC in Fig. 2.

[0048] <Parts Alignment Section> The component alignment unit 3 is a unit that aligns a plurality of components. The component alignment unit 3 aligns the mixed components in a line.

[0049] 4 and 5, the rotor 30 is disposed in the component alignment section 3. Specifically, the component alignment section 3 has a rotor storage chamber 34 that stores the rotor 30. The rotor storage chamber 34 stores the rotor 30 in a rotatable manner. The component alignment section 3 supplies air to the rotor storage chamber 34 to rotate the rotor 30.

[0050] The rotor 30 is provided with through holes 31 through which a plurality of components pass in a line in the vertical direction. In this specification, the "vertical direction" refers to the vertical direction, that is, the Z direction. In the example shown in Fig. 4, the through holes 31 include a first through hole 31a and a second through hole 31b.

[0051] The first through hole 31a guides the multiple components inserted through the component insertion port 41 of the agitator 4 to the second through hole 31b. The second through hole 31b aligns the multiple components in a vertical line and discharges them onto the component conveying path 6.

[0052] The first through hole 31a is a hole that extends in the vertical direction and opens toward the component insertion port 41. The second through hole 31b is a hole that communicates with the first through hole 31a, extends in the vertical direction, and opens toward the component conveying path 6. That is, the opening of the first through hole 31a is formed in the upper surface of the rotor 30, and the opening of the second through hole 31b is formed in the lower surface of the rotor 30.

[0053] The opening of the first through hole 31a is larger than the opening of the second through hole 31b when viewed in the top-bottom direction, and the first through hole 31a becomes smaller from the component insertion port 41 toward the second through hole 31b. That is, the hole diameter of the first through hole 31a becomes smaller toward the second through hole 31b. The second through hole 31b is constant from the portion connected to the first through hole 31a to the opening on the bottom surface of the rotor 30. That is, the hole diameter of the second through hole 31b is constant.

[0054] The diameter of the second through hole 31b is designed to allow a plurality of components to pass through one by one. For example, when a component has a longitudinal direction and a lateral direction, the diameter of the second through hole 31b is larger than the lateral direction and smaller than the longitudinal direction.

[0055] The through hole 31 is defined by a rotor inner wall 31c. The rotor inner wall 31c rotates together with the rotor 30. The rotor inner wall 31c is also a portion that comes into contact with a plurality of components. Therefore, the plurality of components are guided through the through hole 31 by coming into contact with the rotor inner wall 31c. When the rotor inner wall 31c comes into contact with the plurality of components while rotating, a force is applied to the plurality of components in the rotation direction of the rotor 30, which makes it easy to agitate the plurality of components.

[0056] In the first through hole 31a, the rotor inner wall 31c is formed with an inclined surface. Specifically, the rotor inner wall 31c is formed with a tapered shape. In the second through hole 31b, the rotor inner wall 31c is formed with a wall surface extending in the vertical direction.

[0057] The rotor 30 has a rotor body 32 and a plurality of blades 33 .

[0058] The rotor body 32 is a portion in which the through hole 31 is provided. The rotor body 32 has, for example, a cylindrical shape. When viewed from the height direction (Z direction) of the component supplying device 1, the through hole 31 is provided at the center of the rotor body 32.

[0059] The multiple blades 33 are provided on the outer periphery of the rotor body 32. As shown in Fig. 5, when viewed from the height direction (Z direction) of the component supplying device 1, the multiple blades 33 are provided radially at equal intervals on the outer periphery of the rotor body 32. For example, the multiple blades 33 have a plate shape.

[0060] The plurality of blades 33 receive air supplied from the agitating air supply passage 7. This allows the rotor 30 to rotate.

[0061] The rotor storage chamber 34 stores the rotor 30 so as to be horizontally rotatable about a central axis CX1 extending through the through hole 31 in the vertical direction. The rotor storage chamber 34 is formed as a recess having an opening on the upper surface of the component alignment section 3. Specifically, the rotor storage chamber 34 is formed as a cylindrically recessed recess. When viewed from the height direction (Z direction) of the component supplying device 1, the rotor storage chamber 34 has a circular shape and is larger than the outer shape of the rotor 30. The dimensions of the rotor storage chamber 34 are larger than the outer shape of the rotor 30 and smaller than the thickness of the electronic component. Also, when viewed from the height direction (Z direction) of the component supplying device 1, the depth of the rotor storage chamber 34 is larger than the height of the rotor 30.

[0062] The rotor storage chamber 34 has a storage chamber inner wall 35 that defines a space for storing the rotor 30. The storage chamber inner wall 35 regulates the horizontal rotation of the rotor 30. Specifically, when the rotor 30 rotates horizontally, the rotor 30 rotates while contacting the storage chamber inner wall 35. This regulates the rotation center of the rotor 30. That is, the storage chamber inner wall 35 regulates the position in the XY direction of the central axis CX1 that is the rotation center of the rotor 30. This allows the rotor 30 to rotate horizontally around the central axis CX1 that extends inside the through hole 31 in the up-down direction.

[0063] Moreover, the rotor 30 rotates while swinging horizontally in the rotor storage chamber 34. Specifically, the center of rotation of the rotor 30 is not fixed, and the rotor storage chamber 34 is larger than the outer diameter of the rotor 30 when viewed from the height direction (Z direction) of the component supplying device 1. Therefore, when the rotor 30 rotates while contacting the storage chamber inner wall 35, the central axis CX1, which is the center of rotation of the rotor 30, swings horizontally. As a result, the rotor 30 rotates while swinging horizontally. In this way, by the rotor 30 rotating horizontally while swinging, the multiple components can be more agitated when they pass through the through hole 31.

[0064] The part alignment section 3 is provided with a second agitation air supply path 36 that supplies air to the rotor housing chamber 34. The second agitation air supply path 36 is connected to the agitation air supply tube 10 and forms a part of the agitation air supply path 7.

[0065] The second agitating air supply path 36 supplies air into the rotor housing chamber 34. Specifically, the second agitating air supply path 36 is provided in the component alignment unit 3 so that air is supplied toward the multiple blades 33 of the rotor 30. For example, the second agitating air supply path 36 is formed by piping.

[0066] In the component alignment unit 3, air supplied from the second agitation air supply passage 36 collides with the plurality of blades 33, thereby pressing the plurality of blades 33. This causes the rotor 30 to rotate horizontally about the central axis CX1 as the center of rotation.

[0067] In addition, an agitating air introduction path 37 that introduces air from the rotor storage chamber 34 to the component insertion port 41 is provided between the rotor 30 and the agitating unit 4. The agitating air introduction path 37 is a flow path that introduces a portion of the air supplied into the rotor storage chamber 34 to the agitating chamber 40. The agitating air introduction path 37 is formed by the gap between the rotor 30 and the agitating unit 4. The flow path width of the agitating air introduction path 37 is smaller than the dimensions of the components.

[0068] When air is supplied from the second agitation air supply passage 36 to the rotor housing chamber 34 , a portion of the air passes through the agitation air introduction passage 37 and flows from the rotor housing chamber 34 to the agitation chamber 40 of the agitator 4 .

[0069] The part alignment section 3 is provided with a portion of a bypass flow path 70 that diverts a portion of the air in the rotor housing chamber 34 to the stirring section 4. Specifically, the part alignment section 3 is provided with a return flow path 71 and a portion of a return air storage section 72. The bypass flow path 70 will be described later.

[0070] <Stirring section> The mixing unit 4 is disposed above the component alignment unit 3, and while mixing the multiple components, feeds the multiple components into the component alignment unit 3. Specifically, the mixing unit 4 has a mixing chamber 40 that mixes the multiple components.

[0071] 4 and 6, the stirring chamber 40 is provided with a component insertion port 41 that opens toward the through-hole 31 above the rotor 30. The component insertion port 41 is provided on the bottom surface of the component alignment unit 3. When viewed from the height direction (Z direction) of the component supplying device 1, the component insertion port 41 has, for example, a circular shape.

[0072] The stirring chamber 40 is formed by a through-hole that passes vertically through the component alignment unit 3. Specifically, the stirring chamber 40 is formed by a tapered through-hole whose hole diameter decreases from the top surface to the bottom surface of the component alignment unit 3. More specifically, the stirring chamber 40 is formed by a through-hole having an inverted truncated cone shape.

[0073] The stirring chamber 40 has an inner wall 42. The inner wall 42 is inclined so that the dimension (hole diameter) of the stirring chamber 40 becomes smaller toward the part insertion port 41. The inner wall 42 is inclined toward the through hole 31 of the rotor 30. As a result, a plurality of parts are guided by the inner wall 42 and inserted from the part insertion port 41 toward the through hole 31 of the rotor 30.

[0074] A plurality of outlets 43 are provided on the inner wall 42 of the stirring chamber. The plurality of outlets 43 are holes from which air is ejected. The size of the outlets 43 is smaller than the size of the components. The plurality of outlets 43 are provided in the bypass flow path 70. Specifically, the plurality of outlets 43 are provided in the return air supply path 73.

[0075] The bypass flow path 70 diverts a portion of the air supplied to the rotor housing chamber 34 of the part alignment unit 3 and supplies it to the stirring chamber 40 of the stirring unit 4. The bypass flow path 70 has a return flow path 71, a return air storage unit 72, and a return air supply path 73. In this embodiment, the return flow path 71 and a portion of the return air storage unit 72 are provided in the part alignment unit 3, and a portion of the return air storage unit 72 and the return air supply path 73 are provided in the stirring unit 4.

[0076] The return path 71 is a path through which the air supplied to the rotor housing chamber 34 returns. The return path 71 connects the rotor housing chamber 34 and the return air storage section 72. For example, the return path 71 is formed of a pipe. A part of the air supplied from the second agitation air supply path 36 to the rotor housing chamber 34 flows through the return path 71 to the return air storage section 72.

[0077] The return air storage section 72 stores the air that has flowed in from the return path 71. The air stored in the return air storage section 72 flows into the return air supply path 73.

[0078] The return air supply path 73 is a flow path through which the air stored in the return air storage section 72 flows, and communicates with the multiple outlets 43. The air flowing through the return air supply path 73 is ejected from the multiple outlets 43.

[0079] The stirring chamber 40 stirs the multiple parts and feeds the multiple parts from the part insertion port 41 into the through-hole 31. The stirring chamber 40 stirs the multiple parts by using air. Specifically, the stirring chamber 40 stirs the multiple parts by air introduced from the stirring air introduction path 37 and air ejected from the multiple ejection ports 43. In the stirring chamber 40, the stirred multiple parts fall by their own weight, are guided by the stirring chamber inner wall 42, and are fed from the part insertion port 41 into the through-hole 31.

[0080] Fig. 7 is a schematic diagram showing an example of an air flow in the component supplying device 1 according to the first embodiment of the present disclosure. As shown in Fig. 7, when air is supplied from the second agitation air supply path 36 to the rotor housing chamber 34, the air presses the multiple blades 33 of the rotor 30, causing the rotor 30 to rotate horizontally around the central axis CX1. In this manner, the rotor 30 rotates by the force of the air.

[0081] A portion of the air supplied to the rotor housing chamber 34 passes through the agitating air inlet passage 37 and flows from the rotor housing chamber 34 to the part insertion port 41. That is, a portion of the air passes through the agitating air inlet passage 37 and flows from the rotor housing chamber 34 into the agitating chamber 40. This generates a flow of air that rises within the agitating chamber 40. As a result, the multiple parts in the agitating chamber 40 are agitated.

[0082] Another portion of the air supplied to the rotor housing chamber 34 flows from the rotor housing chamber 34 to the stirring chamber 40 through the bypass flow path 70. That is, another portion of the air flows into the stirring chamber 40 through the return flow path 71, the return air storage section 72, and the return air supply path 73. Specifically, the air flowing through the bypass flow path 70 is ejected from the multiple ejection ports 43 into the stirring chamber 40. This generates a flow of air that rises from the multiple ejection ports 43 inside the stirring chamber 40. As a result, the multiple parts in the stirring chamber 40 are agitated.

[0083] In this manner, in this embodiment, the stirring chamber 40 uses the air introduced from the stirring air inlet passage 37 and the air ejected from the multiple ejection ports 43 to stir the multiple components.

[0084] In this embodiment, when air is supplied from the second agitation air supply path 36 to the rotor housing chamber 34, the rotor 30 is lifted by the force of the air. As a result, a conveying air introduction path 38 is formed between the rotor 30 and the part conveying path 6.

[0085] The conveying air inlet path 38 guides air from the rotor storage chamber 34 to the component conveying path 6. The conveying air inlet path 38 is a flow path that guides a portion of the air supplied into the rotor storage chamber 34 to the component conveying path 6. The conveying air inlet path 38 is formed by the gap between the rotor 30 and the component conveying path 6. The flow path width of the conveying air inlet path 38 is smaller than the dimensions of the components.

[0086] When air is supplied from the second agitating air supply path 36 to the rotor housing chamber 34, part of the air passes through the conveying air introduction path 38 and flows from the rotor housing chamber 34 to the component conveying path 6. This makes it possible to use the force of the air supplied to the rotor housing chamber 34 to push out multiple components in the component conveying path 6. In other words, the force of the air used to rotate the rotor 30 can be used to convey the components.

[0087] <Cassette holder> The cassette holding unit 5 is disposed above the mixing unit 4, and holds the component storage cassette 12. The cassette holding unit 5 is provided with a component introduction port 50 through which a plurality of components stored in the component storage cassette 12 are introduced.

[0088] The component introduction port 50 communicates with the stirring chamber 40 of the stirring unit 4. Therefore, a plurality of components are introduced into the component introduction port 50, thereby being introduced into the stirring chamber 40.

[0089] <Parts transport path> The component conveying path 6 conveys the multiple components that have passed through the through hole 31 of the rotor 30 in a line aligned state. The component conveying path 6 conveys the multiple components to the component supply position P1 of the main body 2.

[0090] In this embodiment, a component conveying opening 60 is provided in the component alignment section 3. The component conveying opening 60 is connected to a component conveying tube 9. The component conveying opening 60 and the component conveying tube 9 constitute a component conveying path 6.

[0091] The component transfer opening 60 is a hole that opens toward the through hole 31 below the rotor 30. Specifically, the component transfer opening 60 is a through hole that penetrates the bottom surface of the rotor storage chamber 34 and the bottom surface of the component alignment unit 3. The component transfer opening 60 is provided at a position facing the through hole 31 of the rotor 30 in the vertical direction.

[0092] When viewed from the vertical direction (Z direction), the component transfer opening 60 is larger than the opening of the through hole 31 facing the component transfer opening 60, i.e., the opening of the second through hole 31b. Moreover, the hole diameter of the component transfer opening 60 becomes smaller toward the component transfer tube 9 in the vertical direction (Z direction).

[0093] In this embodiment, the rotor 30 rotates horizontally while swinging horizontally. Therefore, the through hole 31 also swings horizontally. If the component transfer opening 60 is larger than the opening of the second through hole 31b, the multiple components discharged from the second through hole 31b can smoothly pass through the component transfer opening 60 and be moved to the component transfer tube 9 even when the rotor 30 swings horizontally.

[0094] Fig. 8 is a schematic diagram showing an example of the operation of the component supplying device 1 according to the first embodiment of the present disclosure. Fig. 8 shows how a plurality of components 80 are mixed by the component supplying device 1 and aligned in a line.

[0095] 8, a plurality of components 80 are introduced from the component storage cassette 12 into the stirring chamber 40 of the stirring unit 4 through the component introduction port 50 of the cassette holding unit 5. In the stirring chamber 40, the plurality of components 80 are stirred by using the force of air, and the plurality of components 80 are guided from the component insertion port 41 to the through-holes 31 of the rotor 30. Specifically, in the stirring chamber 40, the plurality of components 80 are stirred by air introduced from the stirring air introduction path 37 and air ejected from the plurality of ejection ports 43 through the bypass flow path 70.

[0096] The rotor 30 rotates horizontally while oscillating horizontally about the central axis CX1 due to the force of the air supplied from the second agitation air supply passage 36. The multiple parts 80 fall through the through-hole 31 while contacting the rotor inner wall 31c of the rotor 30. At this time, since the rotor inner wall 31c rotates while oscillating together with the rotor 30, when the multiple parts 80 come into contact with the rotor inner wall 31c in the first through-hole 31a, the multiple parts 80 tend to disperse. That is, the multiple parts 80 are also easily agitated in the first through-hole 31a of the rotor 30.

[0097] After passing through the first through hole 31a, the multiple components 80 are aligned in a line at the second through hole 31b. The multiple components 80 are discharged from the second through hole 31b to the component transport port 60 in a lined-up state. As a result, the multiple components 80 are sent to the component transport path 6 and transported to the component supply position P1.

[0098] Furthermore, when the multiple components 80 are sent to the component conveying path 6, the multiple components 80 within the component conveying path 6 are pushed out by air introduced from the conveying air introduction path 38.

[0099] Fig. 9 is a schematic plan view of an example of the main body portion 2. Fig. 10 is a schematic cross-sectional view taken along line DD in Fig. 9. Fig. 11 is a schematic cross-sectional view taken along line EE in Fig. 9. Fig. 12 is a schematic cross-sectional view taken along line FF in Fig. 9. Fig. 13 is a schematic cross-sectional view taken along line GG in Fig. 9.

[0100] 9, a component supply opening 2a is provided at a component supply position P1 on the upper surface of the main body 2. When a component 80 passes through the component transport path 6 and reaches the component supply position P1, the component 80 is exposed from the component supply opening 2a. A component mounting device 90 picks up the component 80 exposed from the component supply opening 2a.

[0101] Further, a component conveying groove 61 is provided inside the main body 2. The component conveying groove 61 is connected to the component conveying tube 9 and constitutes a part of the component conveying path 6. The component conveying groove 61 has one end and the other end, and the one end is connected to the component conveying tube 9 and the other end is connected to the air suction path 26 across the component supply opening 2a.

[0102] The component conveying groove 61 has a concave shape that opens toward the upper surface of the main body 2. Specifically, the cross section of the component conveying groove 61 has a rectangular shape. The width dimension of the component conveying groove 61 is designed to allow one component 80 to pass through. The component conveying groove 61 is covered by the cover 2b.

[0103] A component detection sensor 14 is disposed in the component conveying groove 61. The component detection sensor 14 detects whether or not a component 80 is present in the component conveying groove 61. The component detection sensor 14 is, for example, an optical sensor, a magnetic sensor, or a capacitance sensor.

[0104] 10 to 12, the cross-sectional shape of the component conveying path 6 changes from a circular shape to a rectangular shape. Specifically, the cross-sectional shape of the component conveying tube 9 changes from an annular shape to a rectangular frame shape toward one end of the component conveying groove 61.

[0105] 9 and 12, the component conveying tube 9 is attached to the main body 2 by a fixture 15. The fixture 15 has a first fixture 15a and a second fixture 15b each having a rectangular recess. The first fixture 15a and the second fixture 15b each have a recess at a corner thereof, which is provided with a clearance 15c. The clearance 15c is a space in which the component conveying tube 9 can deform.

[0106] The component conveying tube 9 is sandwiched between the first fixture 15a and the second fixture 15b while being disposed in the recess of the first fixture 15a and the recess of the second fixture 15b. As a result, the cross-sectional shape of the component conveying tube 9 gradually changes from an annular shape to a rectangular frame shape, as shown in Figs. 10 to 12. Note that, although the fixture 15 in this embodiment has a structure divided into the first fixture 15a and the second fixture 15b, it may also have an integrated structure in which a hole is drilled into a single member for inserting the component conveying tube 9.

[0107] As shown in Fig. 13, the component conveying groove 61 is connected to the conveying air supply path 8. Specifically, the main body 2 is provided with a plurality of second conveying air supply paths 23a that connect the component conveying groove 61 and the first conveying air supply path 23. For example, the plurality of second conveying air supply paths 23a are provided at intervals equal to the pitch of the plurality of components 80 aligned in the component conveying groove 61. Furthermore, the plurality of second conveying air supply paths 23a are inclined toward the conveying direction of the plurality of components 80. The "conveying direction of the plurality of components 80" refers to the direction toward the component supply position P1.

[0108] Air for transporting the multiple components 80 is supplied to the component transport groove 61 from the transport air supply path 8. Specifically, air from the first transport air supply path 23 is supplied through multiple second transport air supply paths 23a into the component transport groove 61. As a result, the multiple components 80 in the component transport groove 61 are pressed by the air and transported toward the component supply position P1.

[0109] An air suction path 26 is connected to the end of the component transport groove 61 (component supply position P1). The air suction path 26 is a flow path that becomes negative pressure by sucking in air. At the end of the component transport groove 61, the component 80 can be sucked toward the component supply position P1 by sucking in air from the air suction path 26. A lid 2c is disposed on the air suction path 26.

[0110] Furthermore, a step 2d is provided at the end of the component conveying groove 61. When the component 80 reaches the component supply position P1, it comes into contact with the step 2d. This positions the component 80 at the component supply position P1.

[0111] FIG. 14 is a flowchart showing an example of a processing operation of the component supplying device 1 according to the first embodiment of the present disclosure.

[0112] 14, in step S1, the part detection sensor 14 detects whether or not a part 80 is present on the part conveying path 6. In this embodiment, the part detection sensor 14 is disposed in a part conveying groove 61 provided in the main body 2. Therefore, the part detection sensor 14 detects whether or not a part 80 is present in the part conveying groove 61. The detection result of the part detection sensor 14 is transmitted to the control unit 20.

[0113] If the component detection sensor 14 detects the presence of a component on the component conveying path 6, the process repeats step S1. On the other hand, if the component detection sensor 14 does not detect the presence of a component on the component conveying path 6, the process proceeds to step S2.

[0114] In step S2, the agitation processing unit 28 of the control unit 20 controls the agitation air control valve 24. Specifically, the agitation processing unit 28 continuously opens and closes the agitation air control valve 24. This causes air to be intermittently supplied to the component alignment unit 3 through the agitation air supply path 7. As a result, the multiple components 80 are agitated in the component alignment unit 3 and the agitation unit 4.

[0115] In step S3, the component detection sensor 14 detects whether or not a component 80 is present on the component conveying path 6. In step S3, if the component detection sensor 14 detects that a component is present on the component conveying path 6, the process returns to step S1. On the other hand, if the component detection sensor 14 does not detect that a component 80 is present on the component conveying path 6, the process proceeds to step S4.

[0116] In step S4, the control unit 20 controls the notification lamp 13. Specifically, the control unit 20 turns on the notification lamp 13. This notifies the user that the component 80 in the component storage cassette 12 has run out.

[0117] According to the component supplying device 1 of the first embodiment of the present disclosure, the following effects can be achieved.

[0118] The component supply device 1 includes a rotor 30, a component alignment unit 3, a stirring unit 4, and a component conveying path 6. The rotor 30 is provided with a through hole 31 through which a plurality of components 80 pass in a line in the vertical direction (Z direction). The component alignment unit 3 has a rotor storage chamber 34 that stores the rotor 30 so that the rotor 30 can rotate horizontally around a central axis CX1 that extends in the through hole 31 in the vertical direction, and supplies air to the rotor storage chamber 34 to rotate the rotor 30. The stirring unit 4 has a component insertion port 41 that opens toward the through hole 31 above the rotor 30, and has a stirring chamber 40 that stirs the plurality of components 80 and inserts the plurality of components 80 from the component insertion port 41 into the through hole 31. The component conveying path 6 conveys the plurality of components 80 that have passed through the through hole 31 in a line. The stirring unit 4 stirs the plurality of components 80 by introducing air supplied to the rotor storage chamber 34 into the stirring chamber 40.

[0119] With this configuration, it is possible to mix and align the multiple components 80. Specifically, the component supplying device 1 can mix the multiple components 80 in the mixing chamber 40 by using the force of the air supplied to the rotor housing chamber 34.

[0120] The rotor 30 has a rotor inner wall 31c that defines the through hole 31 and contacts the multiple components 80. The rotor inner wall 31c rotates together with the rotation of the rotor 30. With this configuration, when the multiple components 80 contact the rotor inner wall 31c, the multiple components 80 are more likely to be agitated by the rotation of the rotor inner wall 31c.

[0121] The rotor 30 rotates horizontally while swinging horizontally within the rotor housing 34. With this configuration, the multiple parts 80 are more easily mixed.

[0122] The rotor storage chamber 34 has a storage chamber inner wall 35 that defines a space for storing the rotor 30. The storage chamber inner wall 35 restricts the horizontal rotation of the rotor 30. With this configuration, the rotor 30 can be stored so as to be horizontally rotatable without fixing the center of rotation of the rotor 30. In addition, the rotor 30 can easily swing.

[0123] Air is introduced from the rotor housing chamber 34 to the mixing chamber 40 through the part insertion port 41. With this configuration, air flows from the rotor housing chamber 34 toward the mixing chamber 40, so that the multiple parts 80 can be mixed more effectively.

[0124] Between the rotor 30 and the agitating unit 4, there is provided an agitating air introduction passage 37 for guiding air from the rotor housing chamber 34 to the component insertion port 41. With this configuration, air can easily flow from the rotor housing chamber 34 toward the agitating chamber 40, enabling the multiple components 80 to be agitated more effectively.

[0125] The through hole 31 includes a first through hole 31a that opens toward the component insertion port 41, and a second through hole 31b that communicates with the first through hole 31a and opens toward the component conveying path 6. The opening of the first through hole 31a is larger than the opening of the second through hole 31b when viewed from the top-bottom direction. The first through hole 31a guides the multiple components 80 inserted from the component insertion port 41 to the second through hole 31b. The second through hole 31b discharges the multiple components 80 in a vertical line to the component conveying path 6. With this configuration, the mixed multiple components 80 can be easily discharged to the component conveying path 6 in a vertical line.

[0126] The rotor 30 has a rotor body 32 provided with a through hole 31, and a plurality of blades 33 provided on the outer periphery of the rotor body 32. With this configuration, the rotor 30 can be easily rotated by the force of air, and the plurality of parts 80 can be more effectively mixed.

[0127] Air is introduced from the rotor housing chamber 34 into the component conveying path 6, and the component conveying path 6 uses the air to convey the multiple components 80. With this configuration, the air used for mixing can be used as a force for conveying the multiple components 80.

[0128] Between the rotor 30 and the component conveying path 6, a conveying air introduction path 38 is provided to guide air from the rotor storage chamber 34 to the component conveying path 6. This configuration makes it easier for air to flow from the rotor storage chamber 34 toward the component conveying path 6, making it easier to convey multiple components 80.

[0129] The component transport path 6 has a component transport opening 60 that opens toward the through hole 31 below the rotor 30. When viewed from the top-bottom direction, the component transport opening 60 is larger than the opening of the through hole 31 that faces the component transport opening 60. With this configuration, the multiple components 80 discharged from the through hole 31 can easily enter the component transport opening 60. In particular, when the rotor 30 rotates horizontally while swinging, the multiple components 80 can easily enter the component transport opening 60.

[0130] The stirring chamber 40 is provided with a plurality of air outlets 43 for ejecting air. The component supplying device 1 further includes a bypass flow path 70 that connects the rotor housing chamber 34 to the plurality of air outlets 43 and guides the air supplied to the rotor housing chamber 34 to the plurality of air outlets 43. With this configuration, the air supplied to the rotor housing chamber 34 can be bypassed and supplied to the stirring chamber 40. This allows the plurality of components 80 to be more effectively stirred in the stirring chamber 40.

[0131] In the present embodiment, the component supplying device 1 includes the cassette holding unit 5 and the notification lamp 13. However, the component supplying device 1 is not limited to this. The cassette holding unit 5 and the notification lamp 13 are not essential components of the component supplying device 1.

[0132] In the present embodiment, an example has been described in which the component conveying path 6 is configured with the component conveying tube 9, the component conveying port 60, and the component conveying groove 61, but the present invention is not limited to this. For example, the component conveying path 6 may include elements other than the component conveying tube 9, the component conveying port 60, and the component conveying groove 61, or any of these may be deleted and / or divided.

[0133] In the present embodiment, an example has been described in which the agitating air supply path 7 is composed of the agitating air supply tube 10, the first agitating air supply path 22, and the second agitating air supply path 36, but the present invention is not limited to this. For example, the agitating air supply path 7 may include elements other than the agitating air supply tube 10, the first agitating air supply path 22, and the second agitating air supply path 36, or any of these may be deleted and / or divided.

[0134] In the present embodiment, an example has been described in which the conveying air supply path 8 is composed of the conveying air supply tube 11, the first conveying air supply path 23, and the second conveying air supply path 23a, but the present invention is not limited to this. For example, the conveying air supply path 8 may include elements other than the conveying air supply tube 11, the first conveying air supply path 23, and the second conveying air supply path 23a, or any of these may be deleted and / or divided.

[0135] In the present embodiment, an example has been described in which the component supplying device 1 includes the bypass flow path 70, but the present invention is not limited to this. The bypass flow path 70 is not an essential component of the component supplying device 1.

[0136] Fig. 15 is a schematic cross-sectional view showing a modified component supplying device 1A Fig. 16 is a schematic view showing an air flow in the modified component supplying device 1A.

[0137] 15, the component supplying device 1A does not include a bypass flow path 70. Moreover, the stirring chamber 40 is not provided with a plurality of ejection ports 43.

[0138] As shown in FIG. 16, in the component supplying device 1A, the agitation chamber 40 agitates a plurality of components 80 with air introduced from the rotor housing chamber 34 through the agitation air introduction passage 37 into the agitation chamber 40.

[0139] In this way, in the component supplying device 1A, the multiple components 80 can be agitated by the force of the air from the agitating air inlet passage 37. That is, in order to agitate the multiple components 80 in the agitating chamber 40, it is not necessary to eject air from the multiple ejection ports 43.

[0140] In the present embodiment, an example has been described in which the control unit 20 controls the agitating air control valve 24 based on the detection result of the component detection sensor 14, but the present invention is not limited to this. For example, the control unit 20 may open and close the agitating air control valve 24 at predetermined intervals regardless of the detection result of the component detection sensor 14.

[0141] For example, when the component conveying path 6 is filled with multiple components 80, when the suction air control valve 27 is open, or when the component mounting device 90 is picking up a component 80, the control unit 20 may close the agitation air control valve 24.

[0142] Although the present invention has been fully described in connection with the preferred embodiment with reference to the accompanying drawings, various changes and modifications will become apparent to those skilled in the art, and such changes and modifications are to be understood as being included within the scope of the present invention as defined by the appended claims, unless they depart therefrom.
