Description

Funnel for parts supply and parts supply device provided with funnel for parts supply

The present invention relates to a hopper for parts supply and a parts supply device provided with the hopper for parts supply.

In Japanese Patent Laid-Open No. JP2017-210343A, a parts supply device is disclosed, including: a funnel storing parts, a disk on which a transport path for the parts supplied from the funnel to move by vibration is formed along the circumferential direction, and a device that vibrates the disk Oscillator.

For example, in the parts supply device described in Japanese Patent Laid-Open No. JP2017-210343A, when the funnel is arranged on the outside of the plate and a ramp is arranged between the funnel and the plate, the overall size of the device is increased, and the parts supply device needs to be secured Larger space.

The present invention is made in view of the above-mentioned problems, and its object is to reduce the size of the parts supply device.

In the present invention, the parts supply funnel supplies the parts to the tray that causes the transported parts to be moved by vibration, and includes: a storage part for storing the parts; and a delivery port for sending out the parts stored in the storage part. The hopper for parts supply is provided on the bottom surface with a predetermined gap between the bottom surface of the tray, and the parts are supplied to the bottom surface through the delivery port.

With the present invention, the parts supply device can be miniaturized.

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

As shown in Figures 1 and 2, the parts supply device 100 includes: a hopper 50 for parts supply (hereinafter referred to as "funnel 50"), a storage part 51 for storing parts, and a hopper oscillator 60 as a hopper vibrating part. The designated amplitude causes the hopper 50 to vibrate in a designated direction; the disk 20 is supplied with parts from the hopper 50; and the disk vibrator 10 as a disk vibrating part vibrates the disk 20 in the circumferential direction with a designated amplitude. FIG. 1 is a side view showing the structure of the parts supply device 100, and FIG. 2 is a plan view of the parts supply device 100. It should be noted that the funnel oscillator 60 and the like are omitted in FIG. 2.

The parts supply device 100 vibrates the hopper 50 by the hopper oscillator 60, thereby sending the parts stored in the hopper 50 to the disk 20. On the other hand, the disk oscillator 10 vibrates the disk 20 to transport the substrate in the vibration direction. The parts supplied into the tray 20 are aligned in a designated posture at the same time, and the parts in the designated posture are carried out from the delivery outlet 20a.

The disk oscillator 10 has an electromagnet (not shown), and transmits a specified period of vibration generated by the alternating current supplied to the electromagnet to the disk 20. It should be noted that the source of vibration is not limited to electromagnets. It may also be a piezoelectric element, or it may be a device that converts the displacement of a solenoid actuator or a fluid pressure actuator into vibration via a mechanism such as a cam. . In order to suppress the transmission of vibrations to the ground, it is preferable to install shock-proof rubber between the disc oscillator 10 and the base 12 on which the disc vibrator 10 is installed, and between the base 12 and the ground.

As shown in FIGS. 1 and 2, the disk 20 is a bottomed cylindrical shape having a bottom surface 21 and a cylindrical portion 22, and is formed of a metal material (for example, aluminum alloy) with good castability and machinability. The disk 20 is fixed to the disk oscillator 10 through a bolt (not shown) inserted into the insertion hole 24 formed at the approximate center. The oscillation caused by the disk oscillator 10 makes the center axis O The center is slightly vibrated in the circumferential direction with a specified period and a specified amplitude. It should be noted that the vibration period and amplitude of the disk 20 are adjusted by a control device (not shown) that controls the alternating current supplied to the disk oscillator 10.

The bottom surface 21 is a receiving surface for receiving the parts sent from the hopper 50, and is inclined so as to gently descend toward the cylindrical portion 22 in order to prevent the parts from stagnating. The cylindrical portion 22 is provided with a transport port 20a for transporting a part in a designated posture to a device in a subsequent process. The delivery port 20a is formed to protrude radially outward from the cylindrical portion 22 so that parts can be easily transferred to and from the device in the subsequent process.

In addition, as shown in FIG. 2, a conveying path 30 is formed on the inner peripheral side of the cylindrical portion 22 along the circumferential direction within a range of less than one week in the circumferential direction. move. That is, since the conveyance path 30 is not formed in a spiral shape, no slope is provided, and it is formed in a slightly horizontal shape from the beginning to the end.

Therefore, as compared with the case where the conveyance path for moving the parts is formed in a spiral shape, since the conveyance path 30 has no slope, the thrust force for moving the parts is small, and the parts can be smoothly moved toward the delivery outlet 20a.

The conveying path 30 is provided with a selection part 31 which allows only parts in a specified posture among the parts moving on the conveying path 30 to move; and a ramp 36 which receives the parts excluded by the selection part 31 and returns it to the conveyance path 30.

The selection part 31 has: a selection surface 32 which is arranged on the same plane as the conveying path 30; and a support surface 33 which supports the parts moving on the selection surface 32. The selection surface 32 and the support surface 33 are planes orthogonal to each other in a radial cross-section, and the selection surface 32 is set to have a smaller inclination angle with respect to the horizontal plane than the support surface 33. Specifically, the angle of the selection surface 32 relative to the horizontal plane is about 30 degrees, on the other hand, the angle of the supporting surface 33 relative to the horizontal plane is about 60 degrees. Therefore, the selection surface 32 supports the lower part of the part moving on the conveying path 30, and the supporting surface 33 supports the side of the part moving on the conveying path 30.

In addition, the width of the selection surface 32 is set to be smaller than the smallest size among the height, width, and thickness of the part. Therefore, among the parts moving on the conveyance path 30, the parts in the specified posture are supported by the selection surface 32 and the supporting surface 33, on the other hand, the parts that are not in the specified posture fall from the selection surface 32.

In addition, the width of the support surface 33, that is, the height from the selection surface 32 to the upper edge of the support surface 33, is set to be equal to or less than the largest of the height, width, and thickness of the part, so that it can be stably aligned. The size of the support for the part in the specified posture. In this way, by limiting the size of the width of the support surface 33 that the part contacts, the contact area between the support surface 33 and the part is reduced, and the resistance when the part moves is reduced, so that the part in the specified posture can be moved along the selected portion 31. Move smoothly.

On the other hand, the ramp 36 has: a receiving surface 37, which is a concave portion provided on the radially inner side with respect to the selected portion 31, and is provided at the portion where the parts fall; a confluence surface 39, which is formed on the same plane as the conveying path 30; and is inclined The surface 38 connects the receiving surface 37 and the confluence surface 39.

The receiving surface 37 is a plane that is parallel to the selection surface 32, that is, has no slope in the circumferential direction. When viewed in a radial cross-section, the receiving surface 37 is formed to be inclined with respect to the horizontal plane similarly to the selection surface 32. Therefore, on the receiving surface 37, the parts dropped from the selection surface 32 can be easily received. It should be noted that when there are many parts falling from the selection surface 32 to the receiving surface 37, the parts further falling from the receiving surface 37 to the bottom surface 21.

The inclined surface 38 has a predetermined inclination in the circumferential direction, and is inclined upward at a predetermined angle from the receiving surface 37 toward the confluence surface 39. Therefore, the parts that have fallen to the receiving surface 37 climb on the inclined surface 38 and move toward the merging surface 39. It should be noted that the inclined surface 38 may also be used as the receiving surface 37, and in this case, the receiving surface 37 may not be provided. In addition, in order to make the parts move smoothly on the ramp 36, the inclination of the connecting portion between the receiving surface 37 and the inclined surface 38, and the connecting portion between the converging surface 39 and the inclined surface 38 may be gentler than other parts.

The confluence surface 39 is a flat portion that is the same plane as the inclined surface 38 and the selection surface 32, and is a portion with a wider width in the conveying path 30.

In addition, the merging surface 39 is formed to be inclined with respect to the horizontal plane similarly to the selection surface 32. Therefore, the parts that move to the merging surface 39 on the inclined surface 38 move toward the supporting surface 33 along the inclination of the merging surface 39. That is, in the merging surface 39, the parts in the specified posture moved along the selection surface 32 and the support surface 33 merge with the parts dropped from the selection surface 32 and moved along the slope 36.

As shown in FIG. 2, the selected portion 31 of the above-mentioned shape and the slope member 36 are arranged adjacent to each other in the radial direction. This is because the selected portion 31 is formed by cutting the ramp 36 with respect to the conveying path 30 having a predetermined width formed along the circumferential direction, specifically the same width as the confluence surface 39. That is, the selection portion 31 and the slope member 36 are integrated and inseparable.

Here, when the height of the part when it is dropped from the selected portion 31 is high, the impact received by the part becomes larger, and a crack or chip may be generated on the part. Especially when the parts are made of ferrite or ceramics, cracks or nicks are likely to occur due to impact. On the other hand, since the conveying path 30 is formed in a range less than one circle in the circumferential direction, compared with the case where the conveying path is formed in a spiral shape, the drop height of the parts can be lowered, so that the occurrence of cracks on the parts can be suppressed. Or the gap situation.

However, even in the case where the transport path 30 is provided in a range that is less than one week in the circumferential direction, there is a possibility that a crack or a chip may be generated on the part due to the difference in the height of the drop of the part. Therefore, in order to reliably suppress the occurrence of cracks or nicks on the parts, the height from the receiving surface 37 that receives the parts dropped from the selection surface 32 to the selection surface 32, that is, the maximum height from the slope member 36 to the selection surface 32, is Set it to be smaller than the largest size among the height, width, and thickness of the part.

In addition, by providing the ramp 36, the parts dropped from the selection portion 31 merge in the middle part of the conveyance path 30. Therefore, compared with the case where the dropped parts are returned to the starting part of the conveying path 30, the time from when the parts are carried in to when they are carried out and subjected to vibrations becomes shorter, and therefore, it is possible to suppress the occurrence of cracks or chipping on the parts. .

However, in the case where the selection portion 31 and the ramp 36 are only provided in one place, it is difficult to align the parts in a designated posture, and the parts that have not returned to the conveying path 30 are returned to the beginning of the conveying path 30, so the parts The vibration time may be longer.

In this way, in order to prevent the parts from being shaken for a long time, the conveying path 30 is provided with the selection part 31 and the slope part 36 in a plurality of places, specifically three places. By providing multiple selection parts 31 and ramp parts 36, it is possible to increase the probability that the parts assume a designated posture, and by increasing the chance that the parts excluded by the selection part 31 will return to the transport path 30, it is possible to shorten the time the parts are transported to the destination. Ship out the time of shock. As a result, it is possible to suppress the occurrence of cracks or chipping in the parts.

It should be noted that the number of the selection portion 31 and the slope member 36 is not limited to three, and may be four or more, or two or less.

In addition to the selection portion 31 and the slope member 36 of the above-mentioned shape, the tray 20 is also provided with a final selection portion 35, which only allows the movement of the parts in the specified posture among the parts that move on the transportation path 30 toward the transportation exit 20a; The part 40 receives the parts excluded by the final selection part 35 and makes them fall toward the bottom surface 21;

The final selection section 35, like the selection section 31, has: a selection surface 32, which is set on the same plane as the conveying path 30; a support surface 33, which supports parts moving on the selection surface 32, and the final selection section 35 also has a turning surface 34, which is formed continuously with the supporting surface 33, and the inclination angle of the transportation outlet 20a with respect to the horizontal plane gradually becomes smaller.

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

In the final selection section 35, similarly to the selection section 31, among the parts moving on the conveyance path 30, the parts in the specified posture are supported by the selection surface 32 and the support surface 33, and the parts reaching the turning surface 34 will be the same as the turning surface 34. The contact surface serves as the bottom surface and is transported out from the transport port 20a. On the other hand, the parts that are not in the specified posture fall from the selection surface 32 and reach the bottom surface 21 via the buffer portion 40. The parts that have fallen to the bottom surface 21 climb on the carry-in part 28 and return to the transport path 30 again.

The carrying-in part 28 is an upward slope connecting the bottom surface 21 and the beginning of the conveying path 30, and the inclination of the carrying-in part 28 is set so that the parts falling to the bottom surface 21 and the parts supplied from the hopper 50 to the bottom surface 21 can go to the beginning of the conveying path 30 The size of the upward movement.

In the tray 20 of the above structure, the conveying path 30 for aligning the postures of the parts is provided along the inner side of the cylindrical portion 22. Therefore, a passage for parts to move is not formed in the center of the tray 20, and a vacant space is formed. In this embodiment, using such an empty space generated in the center of the tray 20, the funnel 50 is arranged in the space. In other words, in the disk 20 of the above-mentioned structure, the conveyance path 30 is not formed in a spiral shape, so it is possible to sufficiently ensure a space for arranging the funnel 50 at the center of the disk 20.

As shown in FIGS. 1 to 4, the hopper 50 is a bottomed cylindrical member formed with a disk-shaped cavity, and the cavity portion becomes a storage portion 51 for storing parts. It should be noted that FIG. 3 is a cross-sectional view taken along the line A-A of FIG. 2, and FIG. 4 is a cross-sectional view taken along the line B-B of FIG. 3.

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, and is provided at the center of the disk 20.

The holding member 61 has a rod-shaped portion 61 a that extends in the horizontal direction and is supported by the support column 62; The hopper holding portion 61b is fixed to the hopper 50 via a fastening member such as a bolt (not shown). In addition, a funnel oscillator 60 is attached to the other end of the rod-shaped portion 61a.

The funnel oscillator 60 has an electromagnet (not shown), and transmits to the funnel 50 vibrations of a predetermined period generated by the alternating current supplied to the electromagnet. It should be noted that the source of vibration is not limited to an electromagnet, and 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 leaf spring not shown, and the leaf springs are arranged such that the bending direction coincides with the longitudinal direction of the rod-shaped portion 61a. Therefore, when the funnel oscillator 60 is driven, the holding member 61 slightly vibrates along the length direction of the rod-shaped portion 61a, that is, along the direction indicated by the arrow X in FIGS. 1 and 2 with a specified period and a specified amplitude. Therefore, the funnel 50 also vibrates slightly.

In order to prevent such micro-vibrations from the funnel 50 from being transmitted to the plate 20 and to prevent the micro-vibrations from the plate 20 from being transmitted to the funnel 50, a designated gap is provided between the bottom of the funnel 50 and the bottom surface 21 of the plate 20. That is, the funnel 50 is provided at the approximate center of the disk 20 in a state where it does not touch the disk 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 oscillator 60. It should be noted that the funnel oscillator 60 is attached to the funnel 50 via the holding member 61, but it may not be provided in the funnel 50.

The hopper 50 has a storage portion 51 that stores parts, and a delivery passage 52 formed to extend from the storage portion 51 to the radially outer side. For the delivery path 52, the cross-section is a U-shaped notch that opens to the storage portion 51. On the other hand, it opens on the outer peripheral surface of the funnel 50. The open portion on the outer peripheral surface of the funnel 50 becomes The parts in the part 51 are sent to the outside through the delivery port 53.

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

In addition, the hopper 50 has a pair of partitions 54 erected so as to sandwich the delivery passage 52. As shown in FIGS. 2 and 3, the partition 54 is a plate-shaped partition portion provided to span a predetermined length from the boundary portion of the storage portion 51 and the delivery path 52 toward the radially inner and upper sides.

In this way, by providing the partition 54 at the boundary between the storage portion 51 and the delivery path 52, when the parts are put into the storage portion 51 from the outside, the parts directly flow into the delivery path 52, and it is possible to prevent the parts from jumping out of the delivery port 53. In addition, it is possible to prevent the parts from falling into the delivery path 52 from a high position of the storage portion 51. In addition, in order to prevent the parts inputted from the outside into the storage portion 51 from directly flowing into the delivery passage 52, in addition to the above-mentioned partition 54, a covering member that covers the upper portion of the delivery passage 52 may be provided.

Here, when the height from the bottom surface 21 of the tray 20 to which the parts are supplied to the lower edge of the delivery port 53 of the hopper 50 is high, the impact on the parts when the parts are sent from the hopper 50 to the tray 20 increases, and the parts may be affected. Cracks or gaps are produced. Especially when the material of the part is fat-grained iron or ceramics, it is easy to produce cracks or nicks due to impact.

Therefore, in this embodiment, in order to suppress the occurrence of cracks or nicks in the parts, the height from the bottom 21 of the tray 20 to the lower edge of the delivery port 53 of the funnel 50 is set to the largest of the height, width, and thickness of the part. The size is below the maximum length of the part. Preferably, the height of the bottom surface 21 of the tray 20 and the height of the lower edge of the delivery port 53 of the funnel 50 are the same height, that is, the lower edge of the delivery port 53 of the funnel 50 and the bottom surface 21 of the tray 20 are on the same plane.

In order to align the lower edge of the delivery port 53 of the hopper 50 and the bottom surface 21 of the tray 20 on the same plane, the bottom surface 21 of the tray 20 is provided with a storage recess 21 a that accommodates the bottom portion of the hopper 50. As shown in FIG. 3, the accommodating recess 21 a is a portion formed by recessing a predetermined depth from the surface of the bottom surface 21, and the outer shape is circular in accordance with the outer shape of the funnel 50.

The funnel 50 is provided with a first gap G1 whose distance from the bottom surface of the storage recess 21a in the direction of the central axis O is a designated gap, and a designated second gap G2 in the radial direction from the inner peripheral surface of the storage recess 21a . The size of the first gap G1 and the size of the second gap G2 are set to a size such that the micro vibration of the funnel 50 is not transmitted to the disk 20 and the micro vibration of the disk 20 is not transmitted to the funnel 50, for example, a size of about 0.2 to 0.8 mm . It should be noted that in order to prevent the parts from falling between the hopper 50 and the plate 20, the size of the second gap G2 is set to be larger than the minimum length of the parts.

As shown in FIGS. 3 and 4, by accommodating at least a part of the bottom of the disk 20 in the accommodating recess 21a formed on the bottom surface 21 of the disk 20, the height of the lower edge of the delivery port 53 of the funnel 50 is equal to that of the bottom surface of the disk 20. The height of 21 is approximately the same height.

In this way, the height of the lower edge of the delivery port 53 of the hopper 50 is approximately the same as the height of the bottom surface 21 of the tray 20, and the height from the bottom surface 21 of the tray 20 to the lower edge of the delivery port 53 of the hopper 50 is less than the maximum length of the part, so The impact that the parts receive when the parts move from the hopper 50 to the disk 20 is reduced, and as a result, the occurrence of cracks or chipping in the parts can be suppressed.

In addition, a plurality of guide grooves 21 b are provided on the bottom surface 21 of the tray 20, and the guide grooves 21 b guide the parts delivered from the hopper 50 to the carrying-in portion 28. The guide groove 21b is a groove formed at a position opposed to the delivery port 53 of the hopper 50, and is formed in an arc shape toward the carrying-in portion 28.

In this way, by forming the guide groove 21b that guides the part to the carrying-in part 28 in the part where the part is sent from the hopper 50, the parts are prevented from moving to the carrying-out port 20a and the buffer part 40. By actively guiding the parts to the conveying path 30, it is possible to improve Delivery efficiency.

Next, with reference to FIGS. 1 to 4, the transportation of parts by the parts supply device 100 provided with the hopper 50 and the tray 20 of the above-mentioned shape will be described.

The hopper oscillator 60 is driven, and the hopper 50 vibrates slightly along the delivery path 52, so that the parts stored in the storage portion 51 of the hopper 50 are delivered from the delivery port 53 to the bottom surface 21 of the tray 20 through the delivery path 52.

The components sent out to the bottom surface 21 of the disk 20 that is slightly vibrated in the circumferential direction by the disk oscillator 10 move to the carrying-in section 28 along the guide groove 21 b, and then climb on the carrying-in section 28 and move to the transport path 30.

The parts moving on the conveyance path 30 are as described above, and only the parts that are in the specified posture in the selection section 31 are selected. And, the parts that have passed the final selection part 35 are shipped out from the shipping outlet 20a.

It should be noted that the supply amount of parts supplied from the hopper 50 to the tray 20 changes with the driving state of the hopper oscillator 60. Therefore, the driving of the hopper oscillator 60 is controlled so that the amount of parts in the tray 20 estimated based on the amount of parts moving on the conveyance path 30 and the amount of parts passing through the export port 20a is an appropriate amount.

In this manner, the parts supply device 100 causes the parts supplied from the hopper 50 arranged at the center of the tray 20 to pass through the transport path 30 provided on the tray 20, align in a designated posture, and then transport them out from the delivery outlet 20a.

The following effects can be achieved by the above-mentioned embodiment.

In the above embodiment, the hopper 50 is provided in the empty space in the center of the tray 20, and the parts are directly supplied from the hopper 50 to the bottom surface 21 of the tray 20. In this way, by arranging the hopper 50 on the bottom surface 21 of the tray 20, the overall size of the parts supply device 100 can be reduced. As a result, the space for installing the parts supply device 100 can be reduced, and the installation of the parts supply device 100 can be improved. Degrees of freedom. In addition, there is no need to provide a ramp between the hopper 50 and the tray 20, so the manufacturing cost of the parts supply device 100 can be reduced.

In addition, in the above-mentioned embodiment, the height of the lower edge of the delivery port 53 of the hopper 50 and the height of the bottom surface 21 of the tray 20 are substantially the same height. In this way, by reducing the drop of the part through which the part passes when moving from the hopper 50 to the plate 20, the impact that the part receives when the part moves from the hopper 50 to the plate 20 can be reduced, and as a result, the occurrence of cracks or chipping in the part can be suppressed. .

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

In the above embodiment, in order to align the lower edge of the delivery port 53 of the funnel 50 and the bottom surface 21 of the tray 20 on the same plane, the bottom side of the funnel 50 is accommodated in the accommodation recess 21 a formed on the bottom surface 21 of the tray 20. Even if the bottom side of the funnel 50 is not stored in the accommodating recess 21a, as long as the height from the bottom 21 of the tray 20 to the lower edge of the delivery port 53 of the funnel 50 is a specified size, for example, the maximum length of the parts is less than or equal to The bottom surface 21 of the disk 20 forms a receiving recess 21a. In this case, the hopper 50 is provided on the bottom surface 21 of the disk 20 in a state where the bottom surface 21 of the disk 20 and the hopper 50 are separated by a first gap G1.

In addition, in the above-described embodiment, the delivery passage 52 is formed linearly in the radial direction from the approximate center of the funnel 50. Instead of this shape, the delivery path 52 may be formed in a curved shape from the approximate center of the funnel 50 toward the radially outer side. For example, by forming the delivery path 52 toward the carrying-in portion 28 in a curved shape, the parts can be smoothly moved toward the transportation path 30.

In addition, in the above-mentioned embodiment, the second gap G2 is provided between the lower edge of the delivery port 53 of the funnel 50 and the bottom surface 21 of the disk 20 in the radial direction. As shown in the modification of FIG. 5, instead of the second gap G2, the following structure may be formed in which an extension portion 52a extending radially outward than the portion where the receiving recess 21a is provided is formed on the lower edge side of the delivery port 53 of the funnel 50, The delivery passage 52 is extended radially outward, and the lower edge of the delivery port 53 of the funnel 50 is positioned above the bottom surface 21 of the disk 20. In addition, FIG. 5 is a cross-sectional view showing a modified example, and this cross-section corresponds to the cross-section shown in FIG. 3. In this way, by forming a structure in which the delivery path 52 overlaps the bottom surface 21, it is possible to surely prevent the parts from falling to the storage recess 21a. It should be noted that in this case, the height from the bottom surface 21 of the tray 20 to the lower edge of the delivery port 53 of the funnel 50 is also set to a specified size. For example, the maximum length of the parts is less than the maximum length of the part, and the funnel 50 is not in contact with the tray 20. Set at the center of the tray 20.

The structure, action, and effect of the embodiment of the present invention will be described below.

The hopper 50 that supplies parts to the tray 20 that moves the transported parts by vibration is provided with a storage part 51 for storing the parts, and a delivery port 53 for sending out the parts stored in the storage part 51. The hopper 50 is compatible with the tray. The bottom surface 21 of 20 is provided on the bottom surface 21 with a designated first gap G1 interposed therebetween, and parts are supplied to the bottom surface 21 through the delivery port 53.

In this structure, the hopper 50 and the bottom surface 21 are provided on the bottom surface 21 of the tray 20 with a specified gap between them, and parts are directly supplied from the hopper 50 to the bottom surface 21 of the tray 20 through the delivery port 53. In this way, by arranging the funnel 50 on the bottom surface 21 of the tray 20, the entire parts supply device 100 can be miniaturized. In addition, as a result, since the space for installing the parts supply device 100 can be reduced, the degree of freedom of installation of the parts supply device 100 can be improved.

In addition, the height from the bottom surface 21 to the lower edge of the delivery port 53 is set to be equal to or less than the maximum length of the part.

In this structure, the height from the bottom surface 21 to the lower edge of the delivery port 53 is set to be equal to or less than the maximum length of the part. In this way, by restricting the height at which the parts fall when the parts move from the hopper 50 to the plate 20, it is possible to reduce the impact of the parts when they move. As a result, it is possible to suppress the occurrence of cracks or chipping in the parts.

In addition, the lower edge of the delivery port 53 and the bottom surface 21 are on the same plane.

In this structure, the lower edge of the delivery port 53 and the bottom surface 21 are on the same plane. In this way, by eliminating the drop of the part through which the part passes when moving from the hopper 50 to the plate 20, it is possible to reduce the impact that the part receives during the movement. As a result, it is possible to suppress the occurrence of cracks or chipping in the parts.

In addition, the hopper 50 further includes a hopper oscillator 60 that vibrates the storage portion 51, and the hopper oscillator 60 vibrates the storage portion 51 in a direction extending from the storage portion 51 to the delivery port 53.

In this structure, the hopper oscillator 60 vibrates the storage portion 51 in the direction in which the delivery path 52 extends, so that the parts are delivered through the delivery path 52. In this way, the delivery of the parts is controlled by vibrating the storage portion 51 in the direction in which the delivery path 52 extends. In this way, by controlling the driving of the hopper oscillator 60, parts can be supplied to the disk 20 according to demand.

In addition, the parts supply device 100 includes: a hopper 50; a disk 20, in which a transport path 30 is formed along the circumferential direction, and the transport path 30 causes the transported parts to move by vibration; and a disk vibrator 10 that vibrates the disk 20. The bottom surface 21 of the tray 20 is formed with a storage recess 21 a that accommodates at least a part of the funnel 50.

In this structure, the bottom surface 21 of the tray 20 is formed with a storage recess 21 a that accommodates at least a part of the funnel 50. In this way, by accommodating at least a part of the funnel 50 in the housing recess 21a formed on the bottom surface 21 of the tray 20, the lower edge of the delivery port 53 of the funnel 50 and the bottom surface 21 of the tray 20 can be on the same plane. As a result, the drop of the part through which the part passes when moving from the hopper 50 to the plate 20 is reduced, and the impact that the part receives during the movement can be reduced. Therefore, it is possible to suppress the occurrence of cracks or chipping in the part.

In addition, the parts supply device 100 includes: a hopper 50; a disk 20, in which a transport path 30 is formed along the circumferential direction, and the transport path 30 causes the transported parts to move by vibration; and a disk vibrator 10 that vibrates the disk 20. The bottom surface 21 of the tray 20 is formed with a guide groove 21 b that guides the parts delivered from the delivery port 53 to the transport path 30.

In this structure, the bottom surface 21 of the tray 20 is formed with a guide groove 21 b that guides the parts delivered from the delivery port 53 to the transport path 30. In this way, by providing the guide groove 21b that guides the parts to the conveying path 30, it is possible to prevent the parts from moving toward the delivery outlet 20a and the buffer portion 40, and to smoothly move the parts toward the conveying path 30, it is possible to align the parts in a designated posture. The parts are efficiently shipped out from the shipping outlet 20a.
