When the hopper is placed outside the bowl and a slope is placed between the hopper and the bowl, as in the parts feeder device described in Patent Document 1, the overall size of the device increases, so it is difficult to use the parts feeder device. It is necessary to secure a relatively large space for installation.

The present invention has been made in view of the above problems, and an object of the present invention is to make a parts feeder device more compact.

It is characterized by the following settings .

According to the present invention, the parts feeder device can be made more compact.

FIG. 1 is a plan view of a parts feeder device according to an embodiment of the present invention. 3 is a sectional view taken along line AA in FIG. 2. FIG. 4 is a sectional view taken along line BB in FIG. 3. FIG. It is a sectional view of a modification of the parts feeder device concerning an embodiment of the present invention.

Hereinafter, a parts feeder device 100 according to an embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the parts feeder device 100 includes a parts feeder hopper 50 (hereinafter referred to as "hopper 50") having a storage section 51 for storing parts, and a parts feeder hopper 50 (hereinafter referred to as "hopper 50") that moves the hopper 50 in a predetermined direction. A hopper vibrator 60 as a hopper vibrator that vibrates with an amplitude of A shaker 10 is provided. FIG. 1 is a side view showing the configuration of the parts feeder 100, and FIG. 2 is a plan view of the parts feeder 100. Note that in FIG. 2, the hopper vibrator 60 and the like are omitted.

The parts feeder device 100 sends the parts stored in the hopper 50 to the bowl 20 by vibrating the hopper 50 with the hopper vibrator 60, and by vibrating the bowl 20 with the bowl vibrator 10, The parts supplied into the bowl 20 are conveyed in the vibration direction and arranged in a predetermined posture, and the parts in the predetermined posture are carried out from the outlet 20a.

The bowl vibrator 10 has an electromagnet (not shown) and transmits vibrations of a predetermined period generated by an alternating current supplied to the electromagnet to the bowl 20. Note that the source of vibration is not limited to an electromagnet, but may be a piezoelectric element, or a device that converts the displacement of a solenoid actuator or a fluid pressure actuator into vibration via a mechanism such as a cam. . Anti-vibration rubber is provided between the bowl vibrator 10 and the pedestal 12 on which the bowl vibrator 10 is installed, and between the pedestal 12 and the floor surface in order to suppress transmission of vibrations to the floor surface. It is preferable.

As shown in FIGS. 1 and 2, the bowl 20 has a bottomed cylindrical shape having a bottom surface 21 and a cylindrical portion 22, and is made of a metal material with good castability and machinability, such as an aluminum alloy. The bowl 20 is fixed to the bowl vibrator 10 via a bolt (not shown) that is inserted through an insertion hole 24 formed approximately in the center, and is vibrated by the bowl vibrator 10 to rotate around the central axis O. It vibrates slightly in the circumferential direction at a predetermined period and with a predetermined amplitude. Note that the vibration period and amplitude of the bowl 20 are adjusted by a control device (not shown) that controls the alternating current supplied to the bowl vibrator 10.

The bottom surface 21 is a receiving surface that receives parts sent out from the hopper 50, and is sloped gently downward toward the cylindrical portion 22 so that the parts do not accumulate. The cylindrical portion 22 is provided with an exit port 20a for transporting the parts in a predetermined posture to a device for subsequent processing. The outlet 20a is formed to protrude outward in the radial direction from the cylindrical portion 22 so that parts can be easily delivered to and from a subsequent process device.

Further, as shown in FIG. 2, on the inner circumferential side of the cylindrical portion 22, a conveyance path 30 along which the parts supplied to the bottom surface 21 move toward the outlet 20a is provided for one rotation in the circumferential direction. It is formed in an area less than . That is, since the conveyance path 30 is not formed in a spiral shape, there is no slope, and the conveyance path 30 is formed substantially horizontally from the start end to the end end.

Therefore, compared to a case where the conveyance path through which the parts move is formed in a spiral shape, since the conveyance path 30 has no slope, the thrust force for moving the parts can be small, so that the parts can be moved toward the outlet 20a. It is possible to move it smoothly.

The conveyance path 30 includes a selection section 31 that allows movement of only parts in a predetermined posture among the parts moving on the conveyance path 30, and a slope 36 that accepts parts excluded by the selection section 31 and returns them to the conveyance path 30. and are provided.

The selection section 31 has a sorting surface 32 provided on the same plane as the conveyance path 30 and a support surface 33 that supports parts moving on the sorting surface 32. The sorting surface 32 and the support surface 33 are planes that are orthogonal to each other in cross section in the radial direction, and the sorting surface 32 is set to have a smaller inclination with respect to the horizontal plane than the support surface 33. Specifically, the angle of the sorting surface 32 with respect to the horizontal plane is about 30 degrees, while the angle of the support surface 33 with respect to the horizontal plane is about 60 degrees. Therefore, the sorting surface 32 supports the parts moving on the conveyance path 30 from below, and the support surface 33 supports the sides of the parts moving on the conveyance path 30.

Further, the width of the sorting surface 32 is set smaller than the smallest dimension among dimensions such as height, width, and thickness of the part. Therefore, among the parts moving on the conveyance path 30, the parts in a predetermined posture are supported by the sorting surface 32 and the support surface 33, while the parts not in the predetermined posture fall from the sorting surface 32. .

In addition, the width of the support surface 33, that is, the height from the sorting surface 32 to the upper edge of the support surface 33, must be equal to or less than the largest dimension of the height, width, and thickness of the part. The size is set such that it can stably support parts in a predetermined posture. In this way, by limiting the width of the support surface 33 with which the parts come into contact and reducing the contact area between the support surface 33 and the parts to reduce the resistance when the parts move, the parts can be kept in a predetermined posture. It becomes possible to move parts smoothly along the selection section 31.

On the other hand, the slope 36 is a recess provided radially inward with respect to the selection section 31, and includes a receiving surface 37 provided at the part where the parts fall and a merging surface 39 formed on the same plane as the conveyance path 30. and an inclined surface 38 connecting the receiving surface 37 and the merging surface 39.

The receiving surface 37 is parallel to the sorting surface 32, that is, it is a plane with no slope in the circumferential direction, and when viewed in a radial cross section, it is formed to be inclined with respect to the horizontal plane like the sorting surface 32. Therefore, the receiving surface 37 can easily receive parts that have fallen from the sorting surface 32. Note that if many parts fall from the sorting surface 32 to the receiving surface 37, the parts will further fall from the receiving surface 37 to the bottom surface 21.

The inclined surface 38 has a predetermined slope in the circumferential direction, and is an upward slope inclined at a predetermined angle from the receiving surface 37 toward the merging surface 39. Therefore, the parts that have fallen onto the receiving surface 37 climb the inclined surface 38 and move to the merging surface 39. Note that the inclined surface 38 may also serve as the receiving surface 37, and in this case, the receiving surface 37 does not need to be provided. In addition, in order to make the movement of parts on the slope 36 smooth, the slope at the connection between the receiving surface 37 and the slope 38 and the connection between the merging surface 39 and the slope 38 is made gentler than other parts. Good too.

The merging surface 39 is a flat portion where the inclined surface 38 and the sorting surface 32 are on the same plane, and is a relatively wide portion in the conveyance path 30.

Further, since the merging surface 39 is formed to be inclined with respect to the horizontal plane like the sorting surface 32, the parts that have moved on the slanted surface 38 and reached the merging surface 39 are moved to the support surface 39 along the inclination of the merging surface 39. will move towards. That is, at the merging surface 39, the parts in a predetermined posture that have moved along the sorting surface 32 and the support surface 33 and the parts that have fallen from the sorting surface 32 and climbed along the slope 36 merge. .

As shown in FIG. 2, the selection portion 31 and the slope 36 having the above-mentioned shapes are provided adjacent to each other in the radial direction. This is because the selection portion 31 is formed by cutting the slope 36 on the conveyance path 30 having a predetermined width formed along the circumferential direction, specifically, the same width as the merging surface 39. be. In other words, the selection section 31 and the slope 36 are inseparable.

Here, if the height at which the parts fall from the selection section 31 is high, the impact received by the parts will be large, and there is a risk that cracks or chips will occur in the parts. In particular, parts made of ferrite or ceramic are susceptible to cracking or chipping due to impact. On the other hand, since the conveyance path 30 is provided in an area that is less than one circumference in the circumferential direction, the height at which the parts fall can be made relatively low compared to the case where the conveyance path is formed in a spiral shape. Therefore, it is possible to suppress the occurrence of cracks and chips in parts.

However, even if the conveyance path 30 is provided in an area less than one round, depending on the height at which the parts fall, cracks or chips may occur in the parts. Therefore, in order to reliably prevent parts from cracking or chipping, the height from the receiving surface 37 that receives parts that have fallen from the sorting surface 32 to the sorting surface 32, that is, from the slope 36 to the sorting surface 32, is The maximum height is set smaller than the largest dimension of the part, such as height, width, and thickness.

Furthermore, by providing the slope 36, the parts that have fallen from the selection section 31 will join together in the middle of the conveyance path 30. For this reason, compared to the case where the fallen parts are returned to the beginning of the transport path 30, the time during which the parts are subjected to vibration from being carried in until being carried out is shortened, resulting in cracks and chips in the parts. It is possible to suppress the occurrence of

However, if the selection section 31 and the slope 36 are provided at only one location, it is difficult to align the parts in a predetermined posture, and the parts that cannot be returned to the conveyance path 30 are placed at the beginning of the conveyance path 30. Since the parts are returned to the parts, there is a risk that the time during which the parts are subjected to vibrations becomes longer.

In order to prevent the parts from being exposed to vibration for a long time as described above, a plurality of selection sections 31 and slopes 36 are provided in the transport path 30, specifically, three locations. By providing a plurality of selection sections 31 and slopes 36 in this way, it is possible to increase the probability that parts will be in a predetermined posture, and the chances of returning parts excluded by the selection section 31 to the conveyance path 30 are increased. , it is possible to shorten the time during which parts are subjected to vibrations from the time they are carried in until the time they are carried out. As a result, it is possible to further suppress cracks and chips from occurring in the parts.

Note that the number of selection units 31 and slopes 36 is not limited to three, and may be four or more or two or less.

In addition to the selection section 31 and the slope 36 having the above-mentioned shapes, the bowl 20 includes a final selection section 35 that allows movement of only parts in a predetermined posture among the parts moving along the conveyance path 30 toward the exit 20a. , a buffer section 40 that accepts the parts excluded by the final selection section 35 and drops them onto the bottom surface 21; and a transport path 30 that transports the parts that have fallen from the buffer section 40 onto the bottom surface 21 and the parts that have been supplied to the bottom surface 21 from the hopper 50. A carrying-in section 28 is provided.

Like the selection section 31, the final selection section 35 has a sorting surface 32 provided on the same plane as the conveyance path 30, and a support surface 33 that supports parts moving on the sorting surface 32. It has a turning surface 34 which is formed continuously and whose inclination with respect to the horizontal plane gradually decreases toward the outlet 20a.

The buffer section 40 is a stepped section having a horizontal plane, and is provided to prevent parts excluded by the final selection section 35 from falling directly onto the bottom surface 21.

In the final selection section 35 as well, like the selection section 31, the parts that are in a predetermined posture among the parts moving on the conveyance path 30 are supported by the sorting surface 32 and the support surface 33, and the parts that have reached the turning surface 34 are , is carried out from the outlet 20a with the surface in contact with the turning surface 34 as the bottom surface. On the other hand, parts that are not in the predetermined posture fall from the sorting surface 32 and reach the bottom surface 21 via the buffer section 40. The parts that have fallen onto the bottom surface 21 climb up the carry-in section 28 and are returned to the conveyance path 30 again.

The carry-in section 28 is an upwardly sloped surface that connects the bottom surface 21 and the starting end of the conveyance path 30, and the slope of the carry-in section 28 is such that the parts that have fallen onto the bottom surface 21 and the parts that have been supplied from the hopper 50 to the bottom surface 21 are connected to the conveyance path. The size is set so that it is possible to climb toward the starting point of 30.

In the bowl 20 configured as described above, the conveyance path 30 for aligning the postures of the parts is provided along the inside of the cylindrical portion 22. Therefore, no passage for parts to move is formed in the center of the bowl 20, leaving an empty space. In this embodiment, the empty space thus created in the center of the bowl 20 is utilized, and the hopper 50 is arranged in this space. In other words, in the bowl 20 configured as described above, since the conveyance path 30 is not formed in a spiral shape, it is possible to secure a sufficient space for arranging the hopper 50 in the center of the bowl 20.

As shown in FIGS. 1 to 4, the hopper 50 is a bottomed cylindrical member in which a bowl-shaped cavity is formed, and the cavity serves as a storage section 51 for storing parts. 3 is a cross-sectional view taken along line AA in FIG. 2, and FIG. 4 is a cross-sectional view taken along line BB in FIG.

As shown in FIG. 1, the hopper 50 is supported by a holding member 61 that holds the hopper 50 and a support column 62 that is erected on the pedestal 12 and supports the holding member 61, so that the hopper 50 is supported by a central portion of the bowl 20. will be installed in

The holding member 61 has a rod-shaped portion 61a that extends in the horizontal direction and is supported by the support column 62, and an annular hopper holding portion 61b that is provided at one end of the rod-shaped portion 61a and holds the outer peripheral surface of the hopper 50. The hopper holding portion 61b is fixed to the hopper 50 via a fastening member such as a bolt (not shown). Further, a hopper vibrator 60 is attached to the other end of the rod-shaped portion 61a.

The hopper vibrator 60 has an electromagnet (not shown), and transmits vibrations of a predetermined period generated by an alternating current supplied to the electromagnet to the hopper 50. Note that the source of vibration is not limited to an electromagnet, but may be a piezoelectric element, or a device that converts the displacement of a solenoid actuator or a fluid pressure actuator into vibration via a mechanism such as a cam. .

The support column 62 and the rod-shaped portion 61a are connected by a plate spring (not shown), and the plate spring is arranged so that its deflection direction coincides with the longitudinal direction of the rod-shaped portion 61a. Therefore, when the hopper vibrator 60 is driven, the holding member 61 is moved at a predetermined period and with a predetermined amplitude along the longitudinal direction of the rod-shaped portion 61a, that is, in the direction indicated by the arrow X in FIGS. 1 and 2. , the hopper 50 also vibrates slightly.

In order to prevent such fine vibrations of the hopper 50 from being transmitted to the bowl 20, and to prevent the fine vibrations of the bowl 20 from being transmitted to the hopper 50, the bottom of the hopper 50 and the bottom surface 21 of the bowl 20 are A predetermined gap is provided between them. That is, the hopper 50 is installed approximately at the center of the bowl 20 without contacting the bowl 20.

The vibration period and amplitude of the hopper 50 are adjusted by a control device (not shown) that controls the alternating current supplied to the hopper vibrator 60. Note that although the hopper vibrator 60 is attached to the hopper 50 via the holding member 61, it may also be provided in the hopper 50.

The hopper 50 has a storage section 51 that stores parts, and a delivery passage 52 that is formed radially outward from the storage section 51. The delivery passage 52 is a notch with a substantially U-shaped cross section, and opens into the storage section 51 while opening at the outer circumferential surface of the hopper 50 . It serves as a delivery port 53 through which parts stored inside are delivered to the outside.

The delivery passage 52 is formed along the longitudinal direction of the rod-shaped portion 61a, that is, in the direction indicated by the arrow X in FIGS. 1 and 2, and is inclined slightly downward toward the delivery port 53. Therefore, when the hopper 50 vibrates slightly along the direction indicated by arrow X, the parts stored in the storage section 51 gradually move along the delivery passage 52 and are delivered from the delivery port 53. .

Further, the hopper 50 has a pair of partition walls 54 erected to sandwich the delivery passage 52 . As shown in FIGS. 2 and 3, the partition wall 54 is a plate-shaped partition provided over a predetermined length radially inward and upward from the boundary between the storage section 51 and the delivery passage 52. be.

By providing the partition wall 54 at the boundary between the storage section 51 and the delivery passage 52 in this way, when parts are thrown into the storage part 51 from the outside, the parts flow directly into the delivery passage 52 and from the delivery port 53. It is possible to prevent the parts from flying out, and it is also possible to prevent the parts from falling from a relatively high position of the storage section 51 into the delivery passage 52. In addition to the partition 54, a cover member may be provided to cover the upper part of the delivery passage 52 in order to prevent parts input from the outside into the storage section 51 from flowing directly into the delivery passage 52.

Here, if the height from the bottom surface 21 of the bowl 20 to which parts are supplied to the lower edge of the delivery port 53 of the hopper 50 is high, the impact that the parts receive when the parts are delivered from the hopper 50 to the bowl 20 is large. This may cause cracks or chips in the parts. In particular, parts made of ferrite or ceramic are susceptible to cracking or chipping due to impact.

Therefore, in this embodiment, in order to suppress cracks and chips from occurring in the parts, the height from the bottom surface 21 of the bowl 20 to the lower edge of the outlet 53 of the hopper 50 is set to the height of the parts, It is set to be less than or equal to the maximum length of the part, which is the largest dimension among dimensions such as width and thickness. More preferably, the height of the bottom surface 21 of the bowl 20 and the height of the lower edge of the outlet 53 of the hopper 50 are the same height, that is, the lower edge of the outlet 53 of the hopper 50 is the same as the bottom surface 21 of the bowl 20. I try to make sure they are on the same page.

In order to make the lower edge of the outlet 53 of the hopper 50 flush with the bottom surface 21 of the bowl 20, the bottom surface 21 of the bowl 20 is provided with an accommodation recess 21a for accommodating the bottom side portion of the hopper 50. As shown in FIG. 3, the accommodation recess 21a is a portion recessed from the surface of the bottom surface 21 by a predetermined depth, and has a circular outer shape that matches the outer shape of the hopper 50.

The hopper 50 is installed with a first gap G1 as a predetermined gap between it and the bottom surface of the accommodation recess 21a in the direction of the central axis O, and has a predetermined first gap G1 between it and the inner peripheral surface of the accommodation recess 21a in the radial direction. 2 with a gap G2 in between. The size of the first gap G1 and the size of the second gap G2 are such that the minute vibrations of the hopper 50 are not transmitted to the bowl 20 and the minute vibrations of the bowl 20 are not transmitted to the hopper 50, for example, 0.2 to 0. The size is set to about .8 mm. Note that in order to prevent parts from falling between the hopper 50 and the bowl 20, the size of the second gap G2 is set larger than the minimum length of the parts.

By accommodating at least a part of the bottom of the bowl 20 in the accommodation recess 21a formed in the bottom surface 21 of the bowl 20, the height of the lower edge of the outlet 53 of the hopper 50 can be adjusted as shown in FIGS. 3 and 4. The height is approximately the same as the height of the bottom surface 21 of the bowl 20.

In this way, the height of the lower edge of the outlet 53 of the hopper 50 and the height of the bottom surface 21 of the bowl 20 almost match, and the height from the bottom surface 21 of the bowl 20 to the lower edge of the outlet 53 of the hopper 50 is the height of the part. By making the length less than or equal to the maximum length, the impact that the parts receive when moving from the hopper 50 to the bowl 20 is reduced, and as a result, it is possible to suppress the occurrence of cracks or chips in the parts.

Furthermore, a plurality of guide grooves 21b are provided on the bottom surface 21 of the bowl 20 to guide the parts sent out from the hopper 50 to the carry-in section 28. The guide groove 21b is a groove formed at a position facing the outlet 53 of the hopper 50, and is formed in an arc shape toward the carry-in portion 28.

By forming the guide groove 21b that guides the parts to the carry-in section 28 in the part where the parts are sent out from the hopper 50, it is possible to prevent the parts from moving toward the carry-out port 20a or the buffer section 40. By suppressing this and actively guiding the parts to the transport path 30, transport efficiency can be improved.

Next, the unloading of parts by the parts feeder device 100 equipped with the hopper 50 and bowl 20 having the above-mentioned shapes will be explained with reference to FIGS. 1 to 4.

When the hopper vibrator 60 is driven and the hopper 50 vibrates slightly along the delivery passage 52, the parts stored in the storage section 51 of the hopper 50 are transferred from the delivery port 53 to the bottom surface 21 of the bowl 20 through the delivery passage 52. sent to.

The parts delivered to the bottom surface 21 of the bowl 20, which vibrates slightly in the circumferential direction by the bowl vibrator 10, move along the guide groove 21b to the carry-in section 28, and then go up the carry-in section 28 and enter the conveyance path 30. reach.

As described above, only those parts that are in a predetermined posture are selected by the selection section 31 to be moved on the conveyance path 30. The parts that have passed through the final selection section 35 are then transported out from the exit 20a.

Note that the amount of parts supplied from the hopper 50 to the bowl 20 changes depending on the driving state of the hopper vibrator 60. For this reason, the hopper vibrator 60 is driven so that the amount of parts in the bowl 20, estimated from the amount of parts moving on the conveyance path 30 and the amount of parts passing through the outlet 20a, is an appropriate amount. controlled by.

In this manner, the parts feeder device 100 transports the parts supplied from the hopper 50 located at the center of the bowl 20 through the transport path 30 provided in the bowl 20, aligning them in a predetermined posture, and transporting them out from the exit 20a.

According to the above embodiment, the following effects are achieved.

In the embodiment described above, the hopper 50 is arranged in an empty space in the center of the bowl 20, and parts are directly supplied from the hopper 50 to the bottom surface 21 of the bowl 20. By arranging the hopper 50 on the bottom surface 21 of the bowl 20 in this way, it becomes possible to make the entire parts feeder device 100 more compact, and as a result, the space for installing the parts feeder device 100 becomes smaller. , the degree of freedom in installing the parts feeder device 100 can be improved. Moreover, since there is no need to interpose a slope between the hopper 50 and the bowl 20, it is also possible to reduce the manufacturing cost of the parts feeder device 100.

Further, in the above embodiment, the height of the lower edge of the outlet 53 of the hopper 50 and the height of the bottom surface 21 of the bowl 20 are approximately the same height. In this way, by reducing the level difference where parts pass when moving from the hopper 50 to the bowl 20, the impact that the parts receive when moving from the hopper 50 to the bowl 20 is reduced, resulting in As a result, it is possible to prevent cracks and chips from occurring in parts.

Next, a modification of the above embodiment will be described.

In the embodiment described above, in order to make the lower edge of the outlet 53 of the hopper 50 flush with the bottom surface 21 of the bowl 20, the bottom side of the hopper 50 is accommodated in the accommodation recess 21a formed in the bottom surface 21 of the bowl 20. There is. Even if the bottom side of the hopper 50 is not accommodated in the storage recess 21a, the height from the bottom surface 21 of the bowl 20 to the lower edge of the outlet 53 of the hopper 50 is set to a predetermined size, for example, less than or equal to the maximum length of the parts. If possible, it is not necessary to form the accommodation recess 21a in the bottom surface 21 of the bowl 20. In this case, the hopper 50 is installed on the bottom surface 21 of the bowl 20 with the first gap G1 interposed between the bottom surface 21 of the bowl 20 and the hopper 50.

Further, in the embodiment described above, the delivery passage 52 is formed in a straight line in the radial direction from approximately the center of the hopper 50. Alternatively, the delivery passage 52 may be formed in a curved shape from approximately the center of the hopper 50 toward the outside in the radial direction. For example, by forming the delivery path 52 in a curved shape toward the loading section 28, parts can be smoothly moved toward the conveyance path 30.

Further, in the embodiment described above, a second gap G2 is provided between the lower edge of the outlet 53 of the hopper 50 and the bottom surface 21 of the bowl 20 in the radial direction. Instead, as in a modification shown in FIG. 5, an extending portion 52a is formed on the lower edge side of the outlet 53 of the hopper 50 and extends radially outward from the portion where the accommodation recess 21a is provided. By extending the delivery passage 52 radially outward, the lower edge of the delivery port 53 of the hopper 50 may be positioned above the bottom surface 21 of the bowl 20. Note that FIG. 5 is a sectional view showing a modification, and shows a cross section corresponding to the cross section shown in FIG. 3. By configuring the delivery passage 52 and the bottom surface 21 to overlap each other in this manner, it is possible to reliably prevent parts from falling into the accommodation recess 21a. In this case as well, the height from the bottom surface 21 of the bowl 20 to the lower edge of the outlet 53 of the hopper 50 is set to a predetermined size, for example, less than the maximum length of the parts, and the hopper 50 is placed in the bowl 20. It is installed approximately at the center of the bowl 20 without touching it.

Hereinafter, the configuration, operation, and effects of the embodiments of the present invention will be collectively described.

The hopper 50 that supplies parts to the bowl 20 that moves the carried parts by vibration includes a storage section 51 that stores the parts and an outlet 53 that sends out the parts stored in the storage section 51. is installed on the bottom surface 21 with a predetermined first gap G1 therebetween, and supplies parts to the bottom surface 21 through the outlet 53.

In this configuration, the hopper 50 is installed on the bottom surface 21 of the bowl 20 with a predetermined gap between it and the bottom surface 21, and parts are directly supplied from the hopper 50 to the bottom surface 21 of the bowl 20 through the outlet 53. be done. By arranging the hopper 50 on the bottom surface 21 of the bowl 20 in this manner, the entire parts feeder device 100 can be made compact. Moreover, as a result, the space for installing the parts feeder device 100 becomes smaller, so that the degree of freedom in installing the parts feeder device 100 can be improved.

Further, the height from the bottom surface 21 to the lower edge of the outlet 53 is set to be less than or equal to the maximum length of the part.

In this configuration, the height from the bottom surface 21 to the lower edge of the outlet 53 is set to be less than or equal to the maximum length of the part. In this way, by limiting the height to which the parts fall when moving from the hopper 50 to the bowl 20, it is possible to reduce the impact that the parts receive during movement. As a result, it is possible to suppress cracks and chips from occurring in the parts.

Further, the lower edge of the outlet 53 is flush with the bottom surface 21 .

In this configuration, the lower edge of the outlet 53 is flush with the bottom surface 21. In this way, by eliminating the step difference in the portion through which the parts pass when moving from the hopper 50 to the bowl 20, it is possible to reduce the impact that the parts receive during movement. As a result, it is possible to suppress cracks and chips from occurring in the parts.
