<Parts alignment section>
The parts aligning section 3 is a part for aligning a plurality of parts. The component aligning unit 3 aligns the stirred components in a row.

As shown in FIGS. 4 and 5 , a rotor 30 is arranged in the component alignment section 3 . Specifically, the parts alignment section 3 has a rotor housing chamber 34 that houses the rotor 30 . The rotor housing chamber 34 rotatably houses the rotor 30 . The parts alignment section 3 supplies air to the rotor housing chamber 34 to rotate the rotor 30 .

The rotor 30 is provided with through-holes 31 through which a plurality of parts pass in a row in the vertical direction. As used herein, the term “vertical direction” refers to the vertical direction and means the Z direction. In the example shown in FIG. 4, the through hole 31 includes a first through hole 31a and a second through hole 31b.

The first through hole 31a guides a plurality of components inserted from the component inlet 41 of the stirring unit 4 to the second through hole 31b. The second through hole 31b aligns a plurality of components in a line in the vertical direction and discharges them to the component transport path 6. As shown in FIG.

The first through hole 31 a is a hole that extends vertically 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 vertically, and opens toward the component transport path 6. As shown in FIG. That is, the upper surface of the rotor 30 is formed with a first through hole 31a, and the lower surface of the rotor 30 is formed with a second through hole 31b.

The opening of the first through-hole 31a is larger than the opening of the second through-hole 31b when viewed in the vertical direction, and the first through-hole 31a becomes smaller from the component inlet 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 of the lower surface of the rotor 30. As shown in FIG. That is, the hole diameter of the second through hole 31b is constant.

The hole diameter of the second through hole 31b is designed to allow passage of a plurality of parts one by one. For example, if the part has a longitudinal direction and a lateral direction, the hole diameter of the second through hole 31b is larger than the lateral direction and smaller than the longitudinal direction.

The through hole 31 is defined by the rotor inner wall 31c. The rotor inner wall 31c rotates as the rotor 30 rotates. The rotor inner wall 31c is also a portion that comes into contact with a plurality of parts. Therefore, the plurality of parts are guided in the through hole 31 by contacting the rotor inner wall 31c. When the inner wall 31c of the rotor comes into contact with a plurality of parts while rotating, a force is applied to the plurality of parts in the direction of rotation of the rotor 30, so that the plurality of parts are easily agitated.

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

The rotor 30 has a rotor main body 32 and a plurality of blades 33 .

The rotor body portion 32 is a portion in which the through holes 31 are provided. The rotor main body 32 has, for example, a cylindrical shape. A through hole 31 is provided in the center of the rotor main body 32 when viewed from the height direction (Z direction) of the component supply device 1 .

A plurality of blades 33 are provided on the outer circumference of the rotor main body 32 . As shown in FIG. 5, when viewed from the height direction (Z direction) of the component supply device 1, the plurality of blades 33 are radially provided on the outer circumference of the rotor main body 32 at regular intervals. For example, the blades 33 have a plate shape.

A plurality of blades 33 receive air supplied from the agitating air supply path 7 . Thereby, the rotor 30 can be rotated.

The rotor housing chamber 34 houses the rotor 30 horizontally rotatably around 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 housing chamber 34 is formed of a concave portion that is cylindrically recessed. When viewed from the height direction (Z direction) of the component supply device 1 , the rotor housing chamber 34 has a circular shape and is larger than the outer shape of the rotor 30 . The dimensions of the rotor housing chamber 34 are larger than the outer shape of the rotor 30 and smaller than the thickness of the electronic component. Further, the depth of the rotor storage chamber 34 is greater than the height of the rotor 30 when viewed from the height direction (Z direction) of the component supply device 1 .

The rotor storage room 34 has a storage room wall 35 that defines a space for storing the rotor 30 . The storage room wall 35 restricts horizontal rotation of the rotor 30 . Specifically, when the rotor 30 rotates horizontally, the rotor 30 rotates while contacting the wall 35 of the storage chamber. Thereby, the center of rotation of the rotor 30 is regulated. That is, the storage chamber wall 35 regulates the position of the central axis CX1, which is the center of rotation of the rotor 30, in the XY direction. As a result, the rotor 30 can horizontally rotate around the central axis CX1 extending in the through hole 31 in the vertical direction.

Further, the rotor 30 rotates in the rotor housing chamber 34 while rocking in the horizontal direction. Specifically, the rotation center 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 supply device 1 . Therefore, when the rotor 30 rotates while contacting the storage chamber wall 35, the central axis CX1, which is the center of rotation of the rotor 30, swings in the horizontal direction. As a result, the rotor 30 rotates while swinging in the horizontal direction. In this manner, the rotor 30 horizontally rotates while swinging, so that the plurality of components can be stirred more when they pass through the through holes 31 .

A second agitating air supply path 36 for supplying air to the rotor storage chamber 34 is provided in the parts alignment section 3 . The second agitation air supply path 36 is connected to the agitation air supply tube 10 and forms part of the agitation air supply path 7 .

For example, the second agitating air supply path 36 is formed by piping.

In the parts aligning section 3, the air supplied from the second agitating air supply path 36 collides with the plurality of blades 33 to press the plurality of blades 33. As a result, the rotor 30 horizontally rotates around the central axis CX1.

A stirring air introduction path 37 is provided between the rotor 30 and the stirring section 4 to guide air from the rotor housing chamber 34 to the component inlet 41 . The stirring air introduction path 37 is a flow path that guides part of the air supplied into the rotor housing chamber 34 to the stirring chamber 40 . A stirring air introduction path 37 is formed by a gap between the rotor 30 and the stirring section 4 . The width of the agitating air introduction path 37 is smaller than the dimensions of the parts.

When air is supplied from the second stirring air supply path 36 to the rotor storage chamber 34 , part of the air passes through the stirring air introduction path 37 and flows from the rotor storage chamber 34 to the stirring chamber 40 of the stirring unit 4 . .

When viewed from the height direction (Z direction) of the component supply device 1, the component insertion port 41 has, for example, a circular shape.

The stirring chamber 40 is formed by a through hole penetrating the component alignment section 3 in the vertical direction. Specifically, the stirring chamber 40 is formed by a tapered through hole having a hole diameter that decreases from the upper surface to the bottom surface of the component alignment section 3 . More specifically, the stirring chamber 40 is formed by an inverted truncated cone-shaped through-hole.

The stirring chamber 40 has a stirring chamber wall 42 . The inner wall 42 of the stirring chamber is inclined so that the size (hole diameter) of the stirring chamber 40 becomes smaller toward the component inlet 41 . The stirring chamber wall 42 is inclined toward the through hole 31 of the rotor 30 . As a result, the plurality of components are guided by the inner wall 42 of the stirring chamber and introduced from the component inlet 41 toward the through hole 31 of the rotor 30 .

A plurality of ejection ports 43 are provided on the stirring chamber wall 42 . The plurality of ejection ports 43 are holes through which air is ejected. The spout 43 has a size smaller than the size of the part. A plurality of ejection ports 43 are provided in the bypass channel 70 . Specifically, the plurality of ejection ports 43 are provided in the return air supply path 73 .

The bypass flow path 70 bypasses part of the air supplied to the rotor storage chamber 34 of the component alignment unit 3 and supplies the air to the stirring chamber 40 of the stirring unit 4 . The bypass channel 70 has a return channel 71 , a return air reservoir 72 and a return air supply channel 73 . In this embodiment, part of the return air reservoir 71 and the return air reservoir 72 are provided in the component alignment section 3 , and part of the return air reservoir 72 and the return air supply path 73 are provided in the stirring section 4 . there is

The circulation path 71 is a path through which the air supplied to the rotor housing chamber 34 is circulated.

Part of the air supplied from the second stirring air supply path 36 to the rotor housing chamber 34 flows through the return path 71 to the return air reservoir 72 .

The return air reservoir 72 stores the air that has flowed in from the return path 71 . The air stored in the return air reservoir 72 flows into the return air supply path 73 .

The return air supply path 73 is a flow path through which the air stored in the return air storage part 72 flows, and communicates with the plurality of ejection ports 43 . Air flowing through the return air supply path 73 is jetted from the plurality of jetting ports 43 .

The stirring chamber 40 stirs a plurality of parts, and throws the plurality of parts into the through hole 31 from the parts inlet 41 . The stirring chamber 40 uses air to stir a plurality of components. Specifically, the agitation chamber 40 agitates a plurality of components by using air introduced from the agitation air introduction path 37 and air ejected from the plurality of ejection ports 43 . In the stirring chamber 40 , a plurality of stirred components fall due to their own weight, are guided by the inner wall 42 of the stirring chamber, and are introduced into the through hole 31 through the component inlet 41 .

FIG. 7 is a schematic diagram showing an example of air flow in the component supply device 1 according to Embodiment 1 of the present disclosure. As shown in FIG. 7, when air is supplied from the second agitating air supply passage 36 to the rotor storage chamber 34, the air presses the plurality of blades 33 of the rotor 30, causing the rotor 30 to move around the central axis CX1. Rotate horizontally around the center. Thus, the rotor 30 is rotated by the force of air.

A part of the air supplied to the rotor housing chamber 34 passes through the stirring air introduction path 37 and flows from the rotor housing chamber 34 to the component inlet 41 . That is, part of the air flows into the stirring chamber 40 from the rotor housing chamber 34 through the stirring air introduction path 37 . As a result, a rising air flow is generated in the stirring chamber 40 . As a result, a plurality of components in the stirring chamber 40 are stirred.

Another part 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 channel 70 . That is, another part of the air flows into the stirring chamber 40 through the return path 71 , the return air reservoir 72 and the return air supply path 73 . Specifically, the air flowing through the bypass channel 70 is jetted into the stirring chamber 40 from the plurality of jetting ports 43 . As a result, an air flow is generated that rises in the stirring chamber 40 from the plurality of ejection ports 43 . As a result, a plurality of components in the stirring chamber 40 are stirred.

As described above, in the present embodiment, the stirring chamber 40 uses the air introduced from the stirring air introduction path 37 and the air ejected from the plurality of ejection ports 43 to stir the plurality of components. .

Further, in this embodiment, when air is supplied from the second stirring air supply path 36 to the rotor housing chamber 34, the rotor 30 is lifted by the force of the air. Thereby, a conveying air introduction path 38 is formed between the rotor 30 and the component conveying path 6 .

A conveying air introduction path 38 is formed by a gap between the rotor 30 and the component conveying path 6 . The width of the conveying air introduction path 38 is smaller than the dimensions of the component.

When air is supplied from the second stirring 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 . As a result, the force of the air supplied to the rotor housing chamber 34 can be utilized to push out the plurality of components within the component transport path 6 . That is, the force of the air for rotating the rotor 30 can be used for component transportation.

In addition, the hole diameter of the component transport port 60 decreases toward the component transport tube 9 in the vertical direction (Z direction).

In this embodiment, the rotor 30 rotates horizontally while rocking in the horizontal direction. Therefore, the through hole 31 also swings horizontally. When the component transfer port 60 is larger than the opening of the second through hole 31b, even when the rotor 30 swings in the horizontal direction, a plurality of components discharged from the second through hole 31b can be smoothly transferred. It can pass through the port 60 and be moved to the component transfer tube 9 .

The plurality of parts 80 drop through the through hole 31 while contacting the rotor inner wall 31 c of the rotor 30 . At this time, since the rotor inner wall 31c rotates while swinging together with the rotor 30, when the plurality of parts 80 come into contact with the rotor inner wall 31c in the first through holes 31a, the plurality of parts 80 are likely to be dispersed. That is, it is easy to agitate the plurality of parts 80 even in the first through holes 31 a of the rotor 30 .

After passing through the first through hole 31a, the plurality of parts 80 are aligned in a row in the second through hole 31b. The plurality of components 80 are discharged from the second through hole 31b into the component transfer port 60 while being aligned in a line. As a result, a plurality of components 80 are sent to the component transport path 6 and transported to the component supply position P1.

Also, when a plurality of components 80 are sent to the component conveying path 6, the plurality of components 80 in the component conveying path 6 are pushed out by the air introduced from the conveying air introduction path 38.
