The other end of the spring member 23 is inserted into the spring holding hole 11a4.

The first case member 11a has an outer peripheral wall portion 13 provided along its edge, and has a storage portion 15 for storing an electronic component EC inside surrounded by the outer peripheral wall portion 13 . A partition wall 14 is arranged in a region surrounded by the outer peripheral wall portion 13 . As shown in FIG. 6, the partition wall 14 forms a downward slope toward the component retraction position P of the rotating member 30 housed in the first case member 11a, and supplies the electronic component EC to the component retraction position P. Includes portion 14a. The storage portion 15 is divided into a first storage portion 15a and a second storage portion 15b by a supply plate portion 14a. That is, the first storage portion 15a is provided above the supply plate portion 14a, and the second storage portion 15b is provided below the first storage portion 15a across the supply plate portion 14a.

The partition wall 14 includes a conveying path forming portion 14b extending downward from the upper end portion of the supply plate portion 14a. The conveying path forming portion 14b is positioned at the rear end portion of the first case member 11a of the outer peripheral wall portion 13, and forms the conveying path 17 together with the vertically extending portion. The transport path 17 connects the first storage section 15a and the second storage section 15b.

Referring to FIG. 6, the component retraction position P in this embodiment is set at a position rotated clockwise by 90° from the topmost portion of the rotary member 30 housed in the first case member 11a. The supply plate portion 14a forms the bottom plate of the first storage portion 15a, and the upper surface thereof forms an inclined surface 15a1 inclined toward such a component magnetic loading position. As a result, the electronic components EC stored in the first storage portion 15a can slide on the inclined surface 15a1 and sequentially move toward the rotating member 30 side. In other words, by providing the supply plate portion 14a, a state in which the electronic components EC can be continuously supplied to the pocket 35 can be achieved.

Referring to FIG. 2E again, the bottom plate portion of the second storage portion 15b is formed by a portion of the outer peripheral wall portion 13 located at the lower end portion of the first case member 11a and extending in the front-rear direction. A bottom plate portion of the second storage portion 15b is formed with an inclined surface 15b1 that slopes down toward the conveying path 17 side.

The electronic component EC moves toward the rotary member 30 by sliding on the inclined surface 15a1 inclined toward the component retraction position P. As shown in FIG. Therefore, the electronic component EC cannot be directly supplied to the rotary member 30 from the second storage portion 15b located below the supply plate portion 14a. Therefore, in the present embodiment, the electronic component EC stored in the second storage portion 15b is transported via the transport path 17 into the first storage portion 15a. The electronic component EC then moves toward the rotating member 30 . Since the component storage case 10 of this embodiment includes the first storage portion 15a and the second storage portion 15b, it can store a large amount of electronic components EC.
Wear.

The first case member 11a includes a rotating member housing portion 16 in which the rotating member 30 is housed. The rotating member housing portion 16 is located forward of the housing portion 15 and is formed in a region where the opening portion 11a2 is provided. The rotating member housing portion 16 is a space that is continuous with the housing portion 15, and by housing the rotating member 30 in such a rotating member housing portion 16, a part of the rotating member 30 is exposed to the housing portion 15. placed in a state. As a result, the electronic component EC housed in the housing portion 15 can be loaded into the pocket 35 provided in the rotating member 30 . In FIG. 2(E), a component recovery section 16a is provided at the lower left of the rotating member storage section 16 to recover electronic components EC that have not been appropriately taken out from the component extraction section 18. As shown in FIG.

Here, the dimensions of the electronic component EC will be described with reference to FIG. 3(B). The shape of the electronic component EC of this embodiment is a rectangular parallelepiped, and of the three mutually orthogonal directions, the direction having the largest dimension is taken as the longitudinal direction, and the dimension along that direction is taken as the length Lec. A dimension along one of two directions orthogonal to the longitudinal direction is defined as a width Wec. Then, let the dimension along the remaining one direction be the height Hec.

Referring to FIG. 3A, a plurality of pockets 35 are provided on the outer peripheral surface 32a of the rim portion 32 of the rotating member 30. As shown in FIG. The pockets 35 are aligned with the direction along the circumferential direction of the rotating member 30 being the column direction and the width direction of the rotating member 30 perpendicular to the column direction being the row direction. In the present embodiment, the pockets 35 included in one row are grouped, and the electronic components EC are taken out from the pocket 35 included in this one group from the component take-out portion 18 at one take-out timing.

Referring to FIG. 4A, each pocket 35 is provided with the width direction of the rim portion 32 (the direction orthogonal to the circumferential direction of the rotating member 30) as the longitudinal direction, as shown in an enlarged view of the X1 portion. The longitudinal dimension of the pocket 35 corresponds to the length Lec of the electronic component EC and is set to be slightly larger than the length Lec. The dimension of the pocket 35 in the lateral direction is set to correspond to the width Wec of the electronic component EC and is set to be slightly larger than the width Wec. The depth of the pocket 35 corresponds to the height Hec of the electronic component EC and is set to a dimension larger than the height Hec.

For example, as shown enlarged in FIG. 4(A), the pockets 35 shown in each figure are arranged five in a row, that is, five rows are drawn. This is for convenience, and in practice, more pockets 35 can be provided.

As described above, the component storage case 10 is provided with the ring-shaped magnet 36 on the side of the inner peripheral surface 32b of the rim portion 32 of the rotating member 30 . By providing the magnet 36, the electronic component EC can be attracted and drawn into the pocket 35 to be loaded. Here, referring to FIG. 4B, the magnet 36 extends along the thickness direction (width direction) of the rotary member 30 perpendicular to the rotation direction (circumferential direction) of the rotary member 30, as shown in an enlarged view of the X2 section. , with alternating north and south poles. As a result, the electronic components EC to be loaded into the respective pockets 35 can be oriented and aligned. That is, by changing the attitude of the electronic component EC so that the longitudinal direction of the electronic component EC coincides with the longitudinal direction of the pocket 35 , the electronic component EC can be properly loaded into the pocket 35 .

Here, referring to FIG. 5, the boundary line between the N pole and the S pole of the magnet 36 passes through the direction along the thickness direction of the rotary member 30 of each pocket 35, that is, through the center of the longitudinal direction of the rotary member. It is provided so as to coincide with the center line CL extending along the circumferential direction of 30 . The probability that the electronic component EC is properly loaded into the pocket 35 can be increased.

The component storage case 10 houses the rotating member 30 in the first case member 11a as indicated by arrow 1a in FIG. formed by joining When the first case member 11a and the second case member 11b are joined together, the shutter guide groove 11a1 and the shutter guide groove 11b1 face each other. The shutter member 20 is slidably supported in the front-rear direction between the shutter guide grooves 11a1 and 11b1 facing each other. At this time, the spring member 23 is attached so as to be held in the spring holding hole 11a4 provided in the first case member 11a and the spring holding hole 22 provided in the shutter member 20. As shown in FIG. As a result, the shutter member 20 is urged to close the component extraction section 18 . The spring force of the spring member 23 is set to such a strength that the shutter member 20 is not easily opened when the component storage case 10 is not attached to the bulk feeder 110, such as when the component storage case 10 is being transported. . In other words, the shutter member 20 cannot be easily opened without using the shutter driving section 116 (see FIG. 7), which will be described later. This prevents the shutter member 20 from being opened during the period from when the electronic component EC is shipped until it is installed on the bulk feeder 110 . As a result, it is possible to avoid the occurrence of mixing of different types of parts.

In this embodiment, the minimum distance S between the outer peripheral edge of the rotating member 30 housed in the first case member 11a and the inner peripheral wall surface of the first case member 11a is greater than the length Lec of the electronic component EC. . In FIG. 6, as shown by enlarging the X3 portion, in the present embodiment, the distance between the top portion of the rotating member 30 and the top plate portion of the outer peripheral wall portion 13 is the minimum interval S. As shown in FIG. By setting such a minimum interval S larger than the length Lec of the electronic component EC, clogging of the electronic component EC in the component storage case 10 can be suppressed. If the minimum distance S is smaller than the length Lec of the electronic component EC, the electronic component EC may be caught between the rotating member 30 and the case main body 11 and hinder the operation of the rotating member 30 . According to the present embodiment, clogging of such electronic components EC can be suppressed.

The introduction of the electronic component EC into the component storage case 10 is performed through the component introduction hole 13b shown in FIG. The component introduction hole 13b may be provided before the first case member 11a and the second case member 11b are joined, or may be drilled after the two are joined. Component introduction hole 13b is sealed with sealing member 13b1 after a predetermined amount of electronic component EC is introduced. The sealing member 13b1 is fixed with an adhesive or by welding so as to prevent the component introduction hole 13b from being opened again. As a result, it is possible to avoid the occurrence of mixing of different types of parts. The first case member 11a and the second case member 11b are joined together by using an adhesive or by welding so that they are not separated from each other.

Both the first case member 11a and the second case member of the present embodiment are made of resin as described above, but both are made of a transparent member. That is, both the first case member 11a and the second case member are made of transparent resin. Thus, the loaded state of the electronic component EC in the pocket 35 can be confirmed from the outside of the component storage case 10 . In the present embodiment, as will be described in detail later, the imaging unit 130 (see FIG. 8) confirms the loaded state of the electronic component EC in the pocket 35 before moving to the component picking unit 18 . By making the first case member 11a and the second case member 11b made of transparent resin, it is possible to check the loaded state of the electronic component EC in the pocket 35 by the imaging unit 130 . It should be noted that only the position where the state of loading of the electronic component EC into the pocket 35 can be confirmed by the imaging unit 130 may be formed with a transparent member. For example, only the inclined portion 13a provided at a position facing the rotating member 30 may be formed of a transparent member in a window shape.

[Bulk feeder]
Next, the bulk feeder 110 on which the parts storage case 10 is installed will be described with reference to FIGS. 7 and 8. FIG. The bulk feeder 110 is provided as part of a component mounter (chip mounter) 100 as shown in FIG. In FIG. 8, the bulk feeder 110 is shown as the area indicated by the dashed lines. A state in which the component storage case 10 is attached to the bulk feeder 110 corresponds to a component supply system.

The bulk feeder 110 has a case mounting portion 111 which is a space having front-rear dimensions and left-right dimensions corresponding to the external dimensions of the component storage case 10 . A first pressing portion 112 a is provided on the upper rear end of the case mounting portion 111 . A second pressing portion 112 b is provided on the rear end side portion of the case mounting portion 111 . Both the first pressing portion 112 a and the second pressing portion 112 b are plate springs and press the rear end portion of the component storage case 10 . Although the first pressing portion 112a and the second pressing portion 112b are made of metal, they may be made of resin as long as they have a desired strength enough to withstand repeated operations. A plunger 113 is provided at the rear end portion of the case mounting portion 111 . The plunger 113 urges the component storage case 10 attached to the case attachment portion 111 forward to prevent the component storage case 10 from rattling.

An air plug 114b is provided on the bottom surface of the case mounting portion 111 near the rear end portion. The air plug 114b is connected to the air supply source 114a shown in FIG. 8 and forms the air supply section 114 together with the air supply source 114a. The air plug 114b is connected to the connecting portion 19 provided in the component storage case 10. As shown in FIG. By operating the air supply source 114a, air is blown into the conveying path 17 (see FIG. 6) formed in the component storage case 10, and the electronic components EC in the second storage portion 15b are first stored. It is transported to the section 15a.

An electromagnet movable along the transport path 17 may be provided instead of the air supply unit 114 . The electromagnet is energized and generates a magnetic force when ascending along the transport path 17, thereby transporting the electronic component EC in the second storage part 15b to the first storage part 15a.

The bulk feeder 110 has a drive gear 115 a that is rotated by a drive motor 115 as a drive portion of the rotating member 30 . The drive gear 115 a meshes with the gear portion 34 provided in the component storage case 10 when the component storage case 10 is attached to the case attachment portion 111 . This allows the rotating member 30 to rotate. The drive motor 115 is capable of stepping to rotate the rotating member 30 by groups of pockets 35 that can be removed at a time, one row in this embodiment.

The bulk feeder 110 has a shutter driver 116 . The shutter drive section 116 includes an actuator 116a, a lever member 116b, a rotary shaft member 116c and a drive pin 116d. The actuator 116 a is housed in a recessed actuator housing portion 111 a provided at the bottom of the case mounting portion 111 . The working portion of the actuator 116a can reciprocate in the front-rear direction. The lever member 116b is housed in a lever member housing portion 111b provided in the inner wall portion of the case mounting portion 111. As shown in FIG. The lever member 116b is pivotally supported by a rotary shaft member 116c so as to swing in the direction of arrow 1c in the lever member housing portion 111b. A working portion of the actuator 116a is connected to the lower end portion of the lever member 116b. The drive pin 116d is provided at the upper end of the lever member 116b. Accordingly, the drive pin 116d can reciprocate generally in the front-rear direction by operating the actuator 116a. The drive pin 116d is engaged with the drive pin engagement hole 21 of the shutter member 20 through the drive pin guide hole 11a3 when the component storage case 10 is attached to the case attachment portion 111. As shown in FIG. As a result, the shutter member 20 can open and close the component extraction section 18 in accordance with the operation of the actuator 116a.

The bulk feeder 110 has a lock member 117 that locks the component storage case 10 to the case mounting portion 111 . The lock member 117 is biased downward by a spring member (not shown) and is provided so as to be movable in the front-rear direction along the upper edge of the case mounting portion 111 . The lock member 117 is provided so as to be positioned at both ends of its range of movement in the front-rear direction. By moving the lock member 117 forward, the front end side of the component storage case 10 attached to the case attachment portion 111 is fixed.

Referring to FIG. 8 , the component mounter 100 includes a bulk feeder 110 as well as a component transfer section 120 , an imaging section 130 and a control section 140 . The component transfer section 120 includes a moving rail 121 , a slider 122 , an elevating rail 123 and a suction nozzle 124 . The moving rail 121 is installed between the bulk feeder 110 and a mounting target (not shown) of the electronic component EC. The slider 122 can move along the moving rail 121 . The elevating rail 123 is provided on the slider 122 . The suction nozzle 124 is provided to move up and down along the lifting rail 123, and can pick up the electronic component EC from the component storage case 10 installed on the bulk feeder 110, as will be described in detail later. The suction nozzles 124 are prepared according to the number of electronic components EC that can be taken out at once.

The imaging unit 130 is provided so as to be able to image the state of the rotating member 30 in the component storage case 10 installed in the bulk feeder 110 . Specifically, the imaging unit 130 can image the state inside each pocket 35 from the component retraction position P in the component storage case 10 installed in the case mounting unit 111 to the topmost portion of the rotating member 30 . is provided as follows. The imaging unit 130 of the present embodiment is provided at a position facing the inclined portion 13a, and images the inside of the component storage case 10 through the inclined portion 13a.

The control unit 140 is electrically connected to the air supply unit 114, the drive motor 115 and the actuator 116a included in the bulk feeder 110, and controls these operations. The control section 140 is also electrically connected to the component transfer section 120 and the imaging section 130 and controls their operations. Based on the image captured by the imaging unit 130, the control unit 140 determines the state of each pocket 35, that is, whether or not each pocket 35 is appropriately loaded with the electronic component EC. Then, based on this determination result, the operation of the suction nozzle 124 is controlled. The details of the control performed by the control unit 140 will be described later.

Here, referring to FIG. 9, a procedure for mounting the component storage case 10 on the bulk feeder 110 will be described. When the component storage case 10 is not attached to the bulk feeder 110, the lock member 117 is moved to the rear end side. When attaching the component storage case 10 to the bulk feeder 110, first, the rear end of the component storage case 10 is inserted between the first pressing portion 112a and the second pressing portion 112b as indicated by an arrow 1e. Next, the component storage case 10 is rotated as indicated by an arrow 1f with the rear end of the component storage case 10 as a fulcrum so as to move the front end side of the component storage case 10 toward the case mounting portion 111 side. At this time, the gear portion 34 is meshed with the drive gear 115a (see FIG. 7). Further, the drive pin 116d is engaged with the drive pin engagement hole 21 (see FIG. 2(D)) through the drive pin guide hole 11a3 (see FIG. 2(E)). After that, the lock member 117 is moved forward to lock the component storage case 10 . This completes the attachment of the component storage case 10 to the bulk feeder 110 . When removing the component storage case 10 from the bulk feeder 110, the component storage case 10 can be easily removed from the bulk feeder 110 by following the reverse procedure.

When the drive pin 116d is positioned on the rear end side as indicated by the solid line in FIG. 10A with the component storage case 10 attached to the bulk feeder 110, the shutter member 20 is closed. be done. On the other hand, when the drive pin 116d is moved toward the front end as indicated by the solid line in FIG. 10B, the shutter member 20 is opened. As a result, the component take-out portion 18 is opened, and the electronic component EC loaded in the pocket 35 can be taken out.

[Removing electronic parts]
Next, taking out the electronic component EC from the component storage case 10 attached to the bulk feeder 110 will be described with reference to the flowchart shown in FIG. 11 . In addition, the electronic parts EC are moved to the part take-out unit 18 for each group to which the plurality of pockets 35 of the present embodiment belong, and the electronic parts EC are taken out from the part storage case 10 . Therefore, the flowchart shown in FIG. 11 shows control for one group. When the mounter 100 is actually in operation, multiple groups are controlled in parallel.

First, the component storage case 10 is attached to the bulk feeder 110 as described above. When the component storage case 10 is attached to the bulk feeder 110, the control unit 140, as a preparatory operation, causes the image capturing unit 130 to move the part that was positioned at the component retraction position P (see FIG. 6) when the component storage case 10 was attached. to a position where it can be imaged.

An electronic component EC (see FIG. 6) stored in the first storage portion 15a of the component storage case 10 is loaded into each pocket 35 by the magnetic force of the magnet 36 at the component retraction position P (loading step). At this time, the direction of the electronic component EC is aligned by the magnetic force of the magnet 36 and loaded into the pocket 35 . However, some pockets 35 may not be properly loaded with electronic components EC. Therefore, the control unit 140 checks the loading state of the electronic component EC with respect to the pocket 35 .

Specifically, in step S1, the control unit 140 captures an image of the pocket 35 for one step of the drive motor 115, that is, one row of the pocket 35 (imaging step).

Then, in step S2 following step S1, the control unit 140 determines whether or not the component in each pocket can be sucked based on the image captured in step S1. It is determined whether or not the pocket 35 capable of adsorbing the EC is included (determining step).

After completing the imaging of the pockets 35 for one row, the control unit 140 sequentially rotates the rotating member 30 by one step to move the pockets 35 of the imaged group to the component extraction unit 18 (moving step). The determining step and the moving step may be performed simultaneously.

If a negative determination (No determination) is made in step S2, the control unit 140 proceeds to step S3. In step S<b>3 , the group to be determined is allowed to pass through the component extraction section 18 without being stopped by the component extraction section 18 . If a negative determination is made in step S2, the group does not include an electronic component EC that can be taken out. Therefore, such a group is allowed to pass through the component picking section 18 to shorten the overall processing time. After executing step S3, the control unit 140 ends the process (END).

On the other hand, when the control unit 140 makes an affirmative determination (Yes determination) in step S2, the process proceeds to step S4. In step S<b>4 , the group to be determined is stopped by the part picking section 18 . In the component picking section 18, the electronic component EC is sucked by the sucking nozzle 124 (see FIG. 8), and the electronic component EC is picked up (picking step).

Specifically, the controller 140 proceeds to step S5 and lowers the suction nozzle 124 corresponding to the pocket 35 loaded with the electronic component EC that can be picked up in step S2. By lowering the suction nozzle 124 only to the pocket 35 loaded with the electronic component EC that can be picked up, useless operation of the mounter 100 can be eliminated.

In step S<b>6 following step S<b>5 , control unit 140 sucks electronic component EC by suction nozzle 124 and raises suction nozzle 124 to directly take out electronic component EC from component storage case 10 . The control unit 140 transfers the extracted component to a desired mounting target by the component transfer unit. As described above, when the component storage case 10 of the present embodiment is used, the electronic component EC can be taken out directly from the component storage case 10, thereby avoiding mixing of different types of components.

After executing step S6, the control unit 140 ends the process (END). This completes the control for one group. Note that the flowchart shown in FIG. 11 shows the control for one group as described above, so even if the processing for the corresponding group is completed, the control for the other groups is continuously executed. It is

The control unit 140 performs control based on the flowchart shown in FIG. 11 for each group, and operates the air supply unit 114 as appropriate. By operating the air supply unit 114, the electronic component EC in the second storage portion 15b can be moved to the first storage portion 15a, thereby continuing to take out the electronic component EC. In addition, the control unit 140 compares the number of electronic components EC stored in the component storage case 10 at the time of shipment with the number of electronic components EC taken out from the component storage case 10, and based on the result, the number of electronic components EC is determined. Stop the eject operation. The stop of the operation to take out the electronic component EC may be determined based on the image captured by the imaging section 130 . In other words, when the ratio of the judgment that the electronic parts EC are not properly loaded into the pocket 35 reaches a predetermined ratio based on the image, it is judged that the electronic parts EC in the parts storage case 10 have been taken out. You may do so.

[effect]
According to the component storage case 10 of the first embodiment, the case main body 11 is provided with the storage portion 15, and the rotating member 30 is partially exposed in the storage portion and rotatably disposed within the case main body. A pocket 35 is provided along the circumferential direction on the outer peripheral surface 32 a of the rotating member 30 , and the electronic component EC loaded in the pocket 35 can be taken out from the component take-out portion 18 . In other words, the electronic components EC are not transferred to the bulk feeder 110 . As a result, the electronic parts EC do not remain in the bulk feeder 110, and even if the bulk feeder 110 is used for different parts, the mixed parts in the bulk feeder 110 do not occur.

The component storage case 10 includes a magnet 36 provided along the inner peripheral surface 32b of the rotating member 30. As shown in FIG. Thereby, the electronic component EC can be pulled into the pocket 35 and loaded.

The magnet 36 alternately has N poles and S poles along the thickness direction of the rotating member 30 perpendicular to the rotating direction of the rotating member 30 . As a result, the directions of the electronic components EC loaded into the pockets 35 can be aligned and aligned.

The magnet 36 is provided so that the boundary line between the N pole and the S pole is aligned with the center line CL of the pocket 35 along the thickness direction of the rotating member 30 . Thereby, in each pocket 35, the effect of aligning the directions of the electronic components EC can be strengthened.

The storage portion 15 forms a downward slope toward a component retraction position P where the electronic component EC is retracted into the pocket 35, and includes a supply plate portion 14a for supplying the electronic component EC to the component retraction position P. 15a. As a result, a state can be created in which the electronic components EC can be continuously supplied to the pocket 35 .

The storage portion 15 includes a second storage portion 15b formed below the first storage portion 15a with the supply plate portion 14a therebetween and connected to the first storage portion 15a via the transport path 17. As shown in FIG. Thereby, a large amount of electronic components EC can be stored in the component storage case 10 .

The component storage case 10 includes a connecting portion 19 to which an air supply source 114a is connected to supply air for moving the electronic components EC in the second storage portion 15b to the first storage portion 15a through the transport path 17. FIG. Thereby, the electronic component EC in the second storage portion 15b can be transported to the first storage portion 15a.

The component take-out section 18 includes a shutter member 20 that can be opened and closed by a shutter driving section 116 provided in the bulk feeder 110 while the case body 11 is attached to the bulk feeder 110 . This prevents the shutter member 20 from being opened during the period from when the electronic component EC is shipped until it is installed on the bulk feeder 110 . As a result, it is possible to avoid the occurrence of mixing of different types of parts.

Both the first case member 11a and the second case member 11b forming the case main body 11 are made of a transparent member. Thereby, the loading state of the electronic component EC in the pocket 35 can be imaged.

A minimum distance S between the outer peripheral edge of the rotary member 30 and the inner peripheral wall surface of the case body 11 is larger than the longitudinal dimension of the electronic component, that is, the length Lec.
Clogging of the electronic components EC in the component storage case 10 can be suppressed.

(Second embodiment)
Next, a component storage case 50 according to a second embodiment will be described with reference to FIGS. 12 to 15. FIG. FIG. 12 is a perspective view of the component storage case 50 of the second embodiment. FIG. 13 is an assembly diagram of the parts storage case 50. As shown in FIG. 14(A) is a side view of a rotating member provided in the component storage case 50, FIG. 14(B) is a side view of a magnet provided in the bulk feeder of the second embodiment, and FIG. 14(C) is shown in FIG. is a front view of the magnet shown. FIG. 15 is an explanatory view showing the state of the inside of the parts storage case 50 after removing the second case member 51b from the parts storage case 50. As shown in FIG. The following description focuses on differences between the first embodiment and the second embodiment. Constituent elements common to the first embodiment and the second embodiment are denoted by the same reference numerals in the drawings, and detailed description thereof will be omitted.

[Parts storage case]
Referring to FIG. 12, the component storage case 50 of the second embodiment includes a second case member 51b instead of the second case member 11b included in the component storage case 10 of the first embodiment. The second case member 51b has a shaft support hole 51b2 similar to that of the second case member 11b of the first embodiment, and a magnet insertion hole 51b3. The magnet insertion hole 51b3 corresponds to an insertion portion for the magnet 52, which will be described later.

Referring to FIG. 13, the rotating member 30 of the second embodiment is not equipped with the magnets 36 (see FIG. 3A) that were equipped in the first embodiment. In the second embodiment, magnets 52 are used instead of the magnets 36 . The magnet 52 is not provided in the component storage case 50, but is arranged inside the rotary member 30 through the magnet insertion hole 51b3 when the component storage case 50 is attached to the bulk feeder 110. FIG.

Referring to FIG. 14(C), the magnet 52 has a sector shape when viewed from the right or left side. The rotary member 30 itself is the same as that employed in the first embodiment, and as shown in FIG. there is The magnet 52 is arranged inside such a rotating member 30, but unlike the magnet 36 of the first embodiment, it does not rotate together with the rotating member 30. FIG. Thus, magnet 52 does not change its position even when bulk feeder 110 is in operation. 14(A) and 14(B) show the magnet 52 viewed from the direction of arrow 1i in FIG. 14(C), and FIG. , N poles and S poles are alternately arranged. Although illustration is omitted here, the magnet 52 has a boundary line between the N pole and the S pole, similar to the magnet 36, which coincides with the center line CL of the pocket 35 along the thickness direction of the rotary member 30. Let it be.

Thus, the magnet 52 exhibits the same function as the magnet 36 of the first embodiment. Note that the magnetic force of the magnet 52 only needs to be exerted when the electronic component EC is loaded into the pocket 35 . Therefore, the shape of the magnet 52 is fan-shaped because it is sufficient to cover the position where the electronic component EC is loaded in the pocket 35 .

In the second embodiment, since the magnets 52 prepared outside the component storage case 50 are used, the weight of the component storage case 50 can be reduced. In addition, the trouble of removing the magnet when discarding the component storage case 50 is eliminated, which is convenient.

The magnet 52 may be prepared on the bulk feeder 110 side and inserted into the rotary member 30 through the magnet insertion hole 51b3 in a state where the component storage case 50 is attached to the bulk feeder 110 .

(Third embodiment)
Next, with reference to FIG. 16, a component storage case 70 of a third embodiment will be described. A component storage case 70 of the third embodiment includes a first case member 71a instead of the first case member 11a of the first embodiment.

The first case member 71a includes a partition wall 74 instead of the partition wall 14 included in the first case member 11a. The partition 74 vertically divides the interior of the first case member 71 a and forms the interior of the storage portion 75 above the partition 74 . That is, in the second embodiment, only the area corresponding to the first storage section 15a in the first embodiment is used as the storage section 75. As shown in FIG. The partition wall 74 also functions as the supply plate portion 14 a in the first embodiment, and its upper surface is an inclined surface 751 .

When the number of electronic components EC stored in the component storage case may be small, the component storage case 70 having such a configuration can be employed. In the component storage case 70, since it is not necessary to transport the electronic component EC from the second storage portion to the first storage portion, the connecting portion 19 included in the component storage case 10 of the first embodiment is also eliminated. .

(Fourth embodiment)
A fourth embodiment will now be described with reference to FIG. In the first embodiment, the electronic components EC are taken out row by row from the component extraction part 18, but in the fourth embodiment, a plurality of rows are taken out from the component extraction part 18 at once.

In the fourth embodiment, the rotating member 30 of the first embodiment is used as it is, and the rotating direction is counterclockwise in FIG. In the fourth embodiment, five rows of pockets 35 arranged in the circumferential direction form one group, and this group is taken out at once. That is, the pocket 35a belonging to the first row, the pocket 35b belonging to the second row, the pocket 35c belonging to the third row, the pocket 35d belonging to the fourth row, and the pocket 35e belonging to the fifth row form one group. . A normal line NL passes through the bottom of each pocket and the center of the opening.

In addition, suction nozzles 124a, 124b, 124c, 124d, and 124e are prepared correspondingly.

In the present embodiment, the electronic components EC are picked up from the component pick-up portion 18 in a state where the third row located in the center of the five rows is positioned at the topmost portion of the rotating member 30 . For this reason, the suction nozzles 124a to 124e descend into the component extraction section 18 at the same timing. For this reason, the opening dimension Lop of the component take-out portion 18 is set so that five rows of electronic components EC can be taken out. For convenience of drawing, FIG. 17 shows only the dimension in the front-rear direction, but the dimension in the left-right direction (the depth direction on the paper surface) is also taken out from the pockets belonging to the target group at once. The dimensions are set to allow

In this manner, the pockets belonging to a plurality of rows are grouped into one group and can be taken out at once, thereby improving work efficiency.

4th Embodiment can utilize the rotating member 30 of 1st Embodiment as it is. In other words, the same rotating member 30 is used whether the group of pockets to be taken out at one time is in a single row or in a plurality of rows.

In this embodiment, five rows of pockets 35 form one group, but the number of rows belonging to one group is not limited to this, and other numbers of rows may be used.

(Fifth embodiment)
A fifth embodiment will now be described with reference to FIG. In the fifth embodiment, as in the fourth embodiment, a plurality of rows (five rows) are taken out from the component take-out portion 18 at once. However, while the rotating member 30 of the first embodiment is used as it is in the fourth embodiment, the rotating member 301 is used in the fifth embodiment. FIG. 18 shows pockets 351a, 351b, 351c, 351d and 351e belonging to one group. A normal line NL passes through the center of the opening of each pocket.

Pocket 351a has a bottom surface 351a1, pocket 351b has a bottom surface 351b1, and pocket 351c has a bottom surface 351c1. The pocket 351d has a bottom surface 351d1, and the pocket 351e has a bottom surface 351e1.

These bottom surfaces 351a1 to 351e1 are horizontal when the circumferential center position of the group is positioned at the top, that is, when the normal line NL passing through the opening of the pocket 351c is aligned with the vertical direction. The vertical heights of the bottom surfaces 351a1 to 351e1 are set to be the same when the bottom surfaces 351a1 to 351e1 are horizontal. Here, the vertical height is the vertical distance from the center of rotation of the rotating member 301 to each of the bottom surfaces 351a1 to 351e1.

As shown in FIG. 18, the electronic components EC are taken out from this group with the center position in the circumferential direction of the group positioned at the top. Therefore, the electronic components EC sucked by the sucking nozzles 124a to 124e are all placed on the horizontal bottom surface. Therefore, the electronic component EC can be stably sucked by the sucking nozzles 124a to 124e.

In addition, since the bottom surfaces 351a1 to 351e1 are sucked with the same height in the vertical direction, the lowering heights of the suction nozzles 124a to 124e can be unified. This makes it possible to unify the time required for sucking the electronic component EC by each of the sucking nozzles 124a to 124e.

Although illustration of the component extraction portion 18 is omitted in FIG. 18, the opening dimension Lop of the component extraction portion 18 is ensured in the same manner as in the fourth embodiment.

(Sixth embodiment)
A sixth embodiment will now be described with reference to FIG. In the sixth embodiment, as in the fourth and fifth embodiments, a plurality of rows (five rows) are taken out from the part take-out part 18 at once. However, in the sixth embodiment, a rotating member 302 different from the other embodiments is used. FIG. 19 shows pockets 352a, 352b, 352c, 352d and 352e belonging to one group. A normal line NL passes through the center of the opening of each pocket.

Pocket 352a has a bottom surface 352a1, pocket 352b has a bottom surface 352b1, and pocket 352c has a bottom surface 352c1. Also, the pocket 352d has a bottom surface 352d1, and the pocket 352e has a bottom surface 352e1.

These bottom surfaces 352a1 to 352e1 are horizontal when the circumferential center position of the group is positioned at the topmost portion, that is, when the normal line NL passing through the opening of the pocket 352c is aligned with the vertical direction.

Further, the depth of each of the pockets 352a to 352e is set to the same depth D. As shown in FIG. Here, the pocket depth is the distance from the center of the pocket opening to the bottom. The depth D of each of the pockets 352a-352e is set to a value that allows stable loading of the electronic component EC.

As shown in FIG. 19, the electronic components EC are taken out from this group with the center position in the circumferential direction of the group positioned at the top. Therefore, the electronic components EC sucked by the sucking nozzles 124a to 124e are all placed on the horizontal bottom surface. Therefore, the electronic components EC can be stably sucked by the sucking nozzles 124a to 124e.

Further, the depth D of each of the pockets 352a to 352e is set to a value that allows stable loading of the electronic component EC. Therefore, even if the rotating member 302 rotates, the electronic components EC loaded in the respective pockets 352a to 352e can be stably held. Also, the electronic component EC can be stably sucked by the sucking nozzles 124a to 124e.

In FIG. 19, illustration of the component extraction portion 18 is omitted, but the opening dimension Lop of the component extraction portion 18 is ensured in the same manner as in the fourth embodiment.

(Seventh embodiment)
Next, a seventh embodiment will be described with reference to FIGS. 20(A) and 20(B). The seventh embodiment includes a spring member 203 that is a leaf spring made of resin instead of the spring member 23 that is a metal coil spring provided in the component storage case 10 of the first embodiment. The spring member 203 is provided with one end fixed to the first case member 11 a and the other end in contact with the shutter member 201 .

The spring member 203 has the same function as the spring member 23, but since it is made of resin, processing such as recycling is facilitated. Since the spring member 23 is made of metal, it must be removed from the component storage case 10 when the component storage case 10 is sent to a treatment process such as recycling. On the other hand, the spring member 203 made of resin can be used in the treatment process without being removed from the first case member 11a, which is convenient.

(Eighth embodiment)
In the above-described second embodiment, the magnets 52 provided outside the component storage case are used to draw the electronic components EC into the pockets 35, and the electronic components EC are oriented and aligned. The following aspects can also be adopted.

That is, it is possible to adopt a mode in which a vacuum suction device is provided instead of the magnet 52 . For example, a hole is provided in the bottom surface of the pocket 35 and a decompression section is provided in the inner peripheral portion of the rotating member 30 . The electronic component EC can be pulled into the pocket 35 by operating such a decompression unit. In this case, by arranging magnets on both sides of the rotating member 30, the electronic components EC can be oriented and aligned.

The above-described embodiments are merely examples for carrying out the present invention, and the present invention is not limited to these. Various modifications of these examples are within the scope of the present invention, and furthermore, the present invention can be modified. It is self-evident from the above description that many other embodiments are possible within the scope.
