Summary of the invention

[0004] Like the parts supply device described in Japanese Patent Application Laid-Open No. JP2017-210343A, when the funnel is arranged outside the disk and a ramp is arranged between the funnel and the disk, the entire device is enlarged, and a larger space needs to be ensured to install the parts supply device.

[0013] Hereinafter, a parts supply device 100 according to an embodiment of the present invention will be described with reference to the drawings.

[0014] like Figure 1 and Figure 2 As shown, the parts supply device 100 comprises: a parts supply funnel 50 (hereinafter referred to as "funnel 50"), having a storage portion 51 for storing parts; a funnel vibrator 60 as a funnel vibrating portion, which vibrates the funnel 50 in a specified direction with a specified amplitude; a disk 20, to which parts are supplied from the funnel 50; and a disk vibrator 10 as a disk vibrating portion, which vibrates the disk 20 in a circumferential direction with a specified amplitude. Figure 1 is a side view showing the structure of the parts supply device 100, Figure 2 FIG. 1 is a plan view of the parts supply device 100. Figure 2 The funnel vibrator 60 and the like are omitted in the illustration.

[0015] The parts supply device 100 vibrates the funnel 50 through the funnel vibrator 60, thereby delivering the parts stored in the funnel 50 to the tray 20. On the other hand, the tray 20 is vibrated by the tray vibrator 10, thereby transporting the parts supplied to the tray 20 in the vibration direction and aligning the parts in a specified posture, and the parts in the specified posture are transported out from the transport outlet 20a.

[0016] The disk vibrator 10 has an electromagnet (not shown) and transmits a vibration of a predetermined period generated by an alternating current supplied to the electromagnet to the disk 20. It should be noted that the vibration source is not limited to the electromagnet, and may be a piezoelectric element, or 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 vibration to the ground, it is preferable to install vibration-proof rubber between the disk vibrator 10 and the base 12 on which the disk vibrator 10 is installed, and between the base 12 and the ground.

[0017] like Figure 1 and Figure 2 As shown, the disk 20 is a bottomed cylindrical object having a bottom surface 21 and a cylindrical portion 22, and is formed of a metal material with good castability and machinability, such as an aluminum alloy. The disk 20 is fixed to the disk vibrator 10 via a bolt (not shown) inserted into an insertion hole 24 formed substantially in the center, and is vibrated by the disk vibrator 10 to micro-vibrate with a predetermined period and a predetermined amplitude in the circumferential direction around the central axis O. 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 vibrator 10.

[0018] The bottom surface 21 is a receiving surface for receiving the parts sent out from the hopper 50, and is inclined so as to gently descend toward the barrel 22 so as not to retain the parts. The barrel 22 is provided with a carrying port 20a for carrying the parts in a predetermined posture to the device of the subsequent process. The carrying port 20a is formed to protrude radially outward from the barrel 22 so as to facilitate the delivery of the parts to the device of the subsequent process.

[0019] In addition, if Figure 2 As shown, a conveying path 30 is formed on the inner peripheral side of the cylinder 22 in a range of less than one circle in the circumferential direction, and the conveying path 30 moves the parts supplied to the bottom surface 21 toward the carrying outlet 20a. That is, the conveying path 30 is not formed in a spiral shape, so there is no slope, and it is formed to be substantially horizontal from the starting end to the terminal end.

[0020] Therefore, compared with a case where the conveying path for moving the parts is formed in a spiral shape, since there is no slope in the conveying path 30 , the thrust for moving the parts is small, and the parts can be smoothly moved toward the carrying-out port 20 a .

[0021] The transport path 30 is provided with: a selection unit 31 that allows only parts with a predetermined posture among the parts moving on the transport path 30 to move; and a ramp 36 that receives the parts rejected by the selection unit 31 and returns them to the transport path 30 .

[0022] The selection portion 31 includes: a sorting surface 32, which is arranged on the same plane as the conveying path 30; and a supporting surface 33, which supports the parts moving on the sorting surface 32. The sorting surface 32 and the supporting surface 33 are planes that are orthogonal to each other in a radial section, and the sorting surface 32 is set to have a smaller inclination angle relative to the horizontal plane than the supporting surface 33. Specifically, the angle of the sorting surface 32 relative to the horizontal plane is about 30 degrees, and on the other hand, the angle of the supporting surface 33 relative to the horizontal plane is about 60 degrees. Therefore, the sorting surface 32 supports the bottom of the parts moving on the conveying path 30, and the supporting surface 33 supports the sides of the parts moving on the conveying path 30.

[0023] In addition, the width of the sorting surface 32 is set to be smaller than the smallest dimension of the height, width, and thickness of the parts. Therefore, among the parts moving on the conveying path 30, the parts in a predetermined posture are supported by the sorting surface 32 and the supporting surface 33, while the parts not in the predetermined posture fall from the sorting surface 32.

[0024] 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, is set to a size that is less than or substantially the same as the largest size of the height, width, and thickness of the part, and can stably support the part in a predetermined posture. In this way, by limiting 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 a predetermined posture can be smoothly moved along the selection portion 31.

[0025] On the other hand, the ramp member 36 has: a receiving surface 37, which is a recessed portion arranged radially inward relative to the selected portion 31 and is arranged at the portion where the part falls; a merging surface 39 formed on the same plane as the conveying path 30; and an inclined surface 38 connecting the receiving surface 37 and the merging surface 39.

[0026] The receiving surface 37 is a plane parallel to the sorting surface 32, that is, a plane without a slope in the circumferential direction, and when viewed in a radial section, it is formed to be inclined relative to the horizontal plane in the same manner as the sorting surface 32. Therefore, the receiving surface 37 can easily receive the parts dropped from the sorting surface 32. It should be noted that when a large number of parts drop from the sorting surface 32 to the receiving surface 37, the parts further drop from the receiving surface 37 to the bottom surface 21.

[0027] The inclined surface 38 has a predetermined slope in the circumferential direction, and is inclined upward at a predetermined angle from the receiving surface 37 toward the merging surface 39. Therefore, the parts dropped onto the receiving surface 37 climb up on the inclined surface 38 and move toward the merging surface 39. It should be noted that the inclined surface 38 may also serve 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 member 36, the slopes of the connection parts between the receiving surface 37 and the inclined surface 38 and the connection parts between the merging surface 39 and the inclined surface 38 may also be gentler than other parts.

[0028] The merging surface 39 is a flat surface portion that is flush with the inclined surface 38 and the sorting surface 32 , and is a relatively wide portion of the transport path 30 .

[0029] In addition, the merging surface 39 is formed to be inclined relative to the horizontal plane in the same manner as the sorting surface 32, so that 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. In other words, on the merging surface 39, the parts in a predetermined posture that move along the sorting surface 32 and the supporting surface 33 merge with the parts that fall from the sorting surface 32 and move up along the ramp 36.

[0030] like Figure 2As shown in the figure, the selection portion 31 of the above shape is arranged adjacent to the ramp member 36 in the radial direction. This is because the selection portion 31 is formed by cutting the ramp member 36 relative to the conveying path 30 having a predetermined width formed along the circumferential direction, specifically, the same width as the merging surface 39. In other words, the selection portion 31 and the ramp member 36 are integral and inseparable.

[0031] Here, when the height at which the part falls from the selected portion 31 is high, the impact on the part becomes greater, and cracks or notches may be generated on the part. In particular, when the material of the part is ferrite or ceramic, cracks or notches are easily generated due to impact. In this regard, the conveying path 30 is set to be formed within a range of less than one circle in the circumferential direction. Therefore, compared with the case where the conveying path is formed in a spiral shape, the height at which the part falls can be lower, so the occurrence of cracks or notches on the part can be suppressed.

[0032] However, even when the conveying path 30 is formed within a range of less than one circle in the circumferential direction, cracks or notches may be generated on the parts due to the difference in the height of the parts falling. Therefore, in order to reliably suppress the occurrence of cracks or notches on the parts, the height from the receiving surface 37 for receiving the parts falling from the sorting surface 32 to the sorting surface 32, that is, the maximum height from the ramp 36 to the sorting surface 32 is set to be smaller than the largest dimension among the height, width, and thickness of the parts.

[0033] In addition, by providing the ramp 36, the parts dropped from the selection portion 31 converge at the middle portion of the conveying path 30. Therefore, compared with the case where the dropped parts are returned to the starting portion of the conveying path 30, the time during which the parts are vibrated from the time they are carried in to the time they are carried out is shortened, thereby suppressing the occurrence of cracks or chips on the parts.

[0034] However, when the selection portion 31 and the ramp member 36 are provided at only one place, it is difficult to align the parts in a predetermined posture, and the parts that have not returned to the conveying path 30 return to the starting portion of the conveying path 30, so the time for which the parts are subjected to vibration may be prolonged.

[0035] In this way, in order to prevent the parts from being subjected to vibration for a longer time, the selection parts 31 and the ramps 36 are provided at multiple locations, specifically three locations, on the conveying path 30. In this way, by providing multiple selection parts 31 and ramps 36, the probability of the parts being in a predetermined posture can be increased, and by increasing the chance that the parts excluded by the selection parts 31 return to the conveying path 30, the time during which the parts are subjected to vibration from being carried in to being carried out can be shortened. As a result, the occurrence of cracks or chips on the parts can be suppressed.

[0036] It should be noted that the number of the selection parts 31 and the ramp members 36 is not limited to three, and may be four or more, or may be two or less.

[0037] In addition to the selection portion 31 and the ramp member 36 of the above-mentioned shape, the tray 20 is provided with: a final selection portion 35, which only allows the movement of parts with a specified posture among the parts moving toward the carrying outlet 20a on the conveying path 30; a buffer portion 40, which receives the parts excluded by the final selection portion 35 and makes them fall to the bottom surface 21; and a carrying-in portion 28, which guides the parts falling from the buffer portion 40 to the bottom surface 21 and the parts supplied to the bottom surface 21 from the funnel 50 to the conveying path 30.

[0038] The final selection part 35 has the same features as the selection part 31: a sorting surface 32, which is arranged on the same plane as the conveying path 30; a supporting surface 33, which supports the parts moving on the sorting surface 32. The final selection part 35 also has a turning surface 34, which is continuously formed with the supporting surface 33, and the inclination angle relative to the horizontal plane gradually decreases toward the carrying outlet 20a.

[0039] The buffer portion 40 is a stepped portion having a horizontal plane, and is provided to prevent the components rejected by the final selection portion 35 from directly falling to the bottom surface 21 .

[0040] In the final selection section 35, similarly to the selection section 31, the parts in a predetermined posture among the parts moving on the conveying path 30 are supported by the sorting surface 32 and the supporting surface 33, and the parts reaching the turning surface 34 are conveyed out from the conveying outlet 20a with the surface in contact with the turning surface 34 as the bottom surface. On the other hand, the parts not in the predetermined posture fall from the sorting surface 32 and reach the bottom surface 21 via the buffer section 40. The parts falling to the bottom surface 21 climb up on the conveying section 28 and return to the conveying path 30 again.

[0041] The carrying-in portion 28 is an upwardly sloping surface connecting the bottom surface 21 and the starting end of the conveying path 30 . The slope of the carrying-in portion 28 is set to a size that allows parts falling to the bottom surface 21 and parts supplied to the bottom surface 21 from the funnel 50 to move upward toward the starting end of the conveying path 30 .

[0042] In the above-mentioned tray 20, the conveying path 30 for aligning the posture of the parts is provided along the inner side of the cylinder 22. Therefore, a passage for the parts to move is not formed in the central part of the tray 20, but an empty space is provided. In the present embodiment, the empty space generated in the central part of the tray 20 is utilized, and the funnel 50 is arranged in the space. In other words, in the above-mentioned tray 20, the conveying path 30 is not formed in a spiral shape, so that a sufficient space for arranging the funnel 50 in the central part of the tray 20 can be ensured.

[0043] like Figures 1 to 4 As shown, the funnel 50 is a bottomed cylindrical member having a disk-shaped hollow, and the hollow portion serves as a storage portion 51 for storing parts. Figure 3 It means along Figure 2 The cross-sectional view of the section along the AA line, Figure 4 Indicates along Figure 3 A cross-sectional view of the cross section of line BB.

[0044] like Figure 1 As shown, the funnel 50 is supported by a holding member 61 that holds the funnel 50 and a support column 62 that is erected on the pedestal 12 and supports the holding member 61 , and is disposed in the center of the tray 20 .

[0045] The holding member 61 includes a rod-shaped portion 61a extending in the horizontal direction and supported by a support column 62, and an annular funnel holding portion 61b provided at one end of the rod-shaped portion 61a to hold the outer peripheral surface of the funnel 50. The funnel holding portion 61b is fixed to the funnel 50 via a fastening member such as a bolt (not shown). In addition, the funnel vibrator 60 is mounted on the other end of the rod-shaped portion 61a.

[0046] The funnel vibrator 60 has an electromagnet (not shown) and transmits vibration of a predetermined period generated by an alternating current supplied to the electromagnet to the funnel 50. It should be noted that the vibration source is not limited to the electromagnet, but may be a piezoelectric element, or 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.

[0047] The support column 62 is connected to the rod-shaped portion 61a by a leaf spring (not shown), and the leaf spring is configured so that the bending direction is consistent with the length direction of the rod-shaped portion 61a. Therefore, when the funnel vibrator 60 is driven, the holding member 61 is along the length direction of the rod-shaped portion 61a, that is, along the Figure 1 and Figure 2 The direction indicated by the arrow X in the middle vibrates slightly with a predetermined period and a predetermined amplitude, and the funnel 50 also vibrates slightly accordingly.

[0048] In order to prevent the microvibration of the funnel 50 from being transmitted to the disk 20, and in order to prevent the microvibration of the disk 20 from being transmitted to the funnel 50, a predetermined gap is provided between the bottom of the funnel 50 and the bottom surface 21 of the disk 20. In other words, the funnel 50 is provided at the approximate center of the disk 20 without contacting the disk 20.

[0049] The vibration period and amplitude of the funnel 50 are adjusted by a control device (not shown) that controls the AC current supplied to the funnel vibrator 60. The funnel vibrator 60 is attached to the funnel 50 via the holding member 61, but may not be provided thereto.

[0050] The funnel 50 has a storage portion 51 for storing parts, and a delivery passage 52 formed to extend radially outward from the storage portion 51. The delivery passage 52 has a substantially U-shaped notch in cross section, opens to the storage portion 51, and opens on the outer peripheral surface of the funnel 50. The portion opened on the outer peripheral surface of the funnel 50 serves as a delivery port 53 for delivering the parts stored in the storage portion 51 to the outside.

[0051] The delivery path 52 extends along the length direction of the rod-shaped portion 61a, that is, Figure 1 and Figure 2 The funnel 50 is formed in the direction indicated by the arrow X, and is inclined in a manner slightly descending toward the delivery port 53. Therefore, when the funnel 50 is slightly vibrated in the direction indicated by the arrow X, the parts stored in the storage portion 51 slowly move along the delivery passage 52 and are delivered from the delivery port 53.

[0052] In addition, the funnel 50 has a pair of partition walls 54 erected so as to sandwich the delivery passage 52. Figure 2 and Figure 3 As shown, the partition wall 54 is a plate-shaped partition portion provided to extend radially inward and upward over a predetermined length from the boundary portion between the storage portion 51 and the delivery passage 52 .

[0053] In this way, by providing the partition wall 54 at the boundary between the storage section 51 and the delivery passage 52, when the parts are put into the storage section 51 from the outside, the parts directly flow into the delivery passage 52, which can prevent the parts from jumping out of the delivery port 53, and can prevent the parts from falling from a higher position of the storage section 51 to the delivery passage 52. In addition, in order to prevent the parts put into the storage section 51 from the outside from directly flowing into the delivery passage 52, in addition to the partition wall 54, a covering member covering the upper part of the delivery passage 52 can also be provided.

[0054] 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 delivered from the hopper 50 to the tray 20 becomes greater, and cracks or chips may be generated in the parts. In particular, when the material of the parts is ferrite or ceramic, cracks or chips are easily generated due to impact.

[0055] Therefore, in this embodiment, in order to suppress the occurrence of cracks or notches in the parts, 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 set to be less than the largest dimension of the height, width, and thickness of the parts, that is, the maximum length of the parts. More 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.

[0056] In order to make 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, a storage recess 21a for storing the bottom side portion of the funnel 50 is provided on the bottom surface 21 of the tray 20. Figure 3 As shown, the storage recess 21 a is a portion that is 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 funnel 50 .

[0057] The funnel 50 is provided with a first gap G1 as a predetermined gap between it and the bottom surface of the storage recess 21a in the direction of the central axis O, and a predetermined second gap G2 between it and the inner peripheral surface of the storage recess 21a in the radial direction. The size of the first gap G1 and the size of the second gap G2 are set to a size that the microvibration of the funnel 50 is not transmitted to the disk 20 and the microvibration 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 funnel 50 and the disk 20, the size of the second gap G2 is set to be smaller than the minimum length of the parts.

[0058] like Figure 3 and Figure 4 As shown, by accommodating at least a portion of the bottom of the funnel 50 in the accommodation recess 21 a formed on the bottom surface 21 of the tray 20 , the height of the lower edge of the delivery port 53 of the funnel 50 is substantially the same as the height of the bottom surface 21 of the tray 20 .

[0059] In this way, the height of the lower edge of the delivery port 53 of the funnel 50 is approximately the same as the height of the bottom surface 21 of the disk 20, and the height from the bottom surface 21 of the disk 20 to the lower edge of the delivery port 53 of the funnel 50 is less than the maximum length of the part, thereby reducing the impact on the part when the part moves from the funnel 50 to the disk 20. As a result, cracks or gaps in the part can be suppressed.

[0060] The bottom surface 21 of the tray 20 is provided with a plurality of guide grooves 21b for guiding the parts delivered from the hopper 50 to the carrying-in portion 28. The guide grooves 21b are grooves formed at positions facing the delivery port 53 of the hopper 50 and are formed in an arc shape toward the carrying-in portion 28.

[0061] In this way, by forming the guide groove 21b for guiding the parts to the carrying-in section 28 at the portion where the parts are sent out from the hopper 50, the parts are suppressed from moving toward the carrying-out port 20a and the buffer section 40. By actively guiding the parts to the conveying path 30, the conveying efficiency can be improved.

[0062] Next, refer to Figures 1 to 4 , the unloading of parts by the parts supply device 100 having the funnel 50 and the tray 20 of the above-mentioned shape will be described.

[0063] The funnel vibrator 60 is driven to slightly vibrate the funnel 50 along the delivery path 52 , so that the parts stored in the storage portion 51 of the funnel 50 are delivered from the delivery port 53 to the bottom surface 21 of the tray 20 through the delivery path 52 .

[0064] The parts fed to the bottom surface 21 of the disk 20 slightly vibrated in the circumferential direction by the disk vibrator 10 move to the carrying-in portion 28 along the guide groove 21 b , and then move up on the carrying-in portion 28 to the transport path 30 .

[0065] As described above, among the components moving on the transport path 30, only the components that are in a predetermined posture are selected by the selection unit 31. Then, the components that have passed the final selection unit 35 are carried out from the carrying-out port 20a.

[0066] It should be noted that the amount of parts supplied from the hopper 50 to the tray 20 changes according to the driving state of the hopper vibrator 60. Therefore, the driving of the hopper vibrator 60 is controlled so that the amount of parts in the tray 20 estimated from the amount of parts moving on the conveying path 30 and the amount of parts passing through the carrying port 20a is an appropriate amount.

[0067] In this way, the parts supplying device 100 allows the parts supplied from the hopper 50 disposed at the center of the tray 20 to pass through the conveying path 30 provided on the tray 20, align them in a predetermined posture, and then carry them out from the carrying-out port 20a.

[0068] According to the above-described embodiment, the following effects are achieved.

[0069] In the above embodiment, the funnel 50 is provided in the vacant space in the center of the tray 20, and the parts are directly supplied from the funnel 50 to the bottom surface 21 of the tray 20. In this way, by arranging the funnel 50 on the bottom surface 21 of the tray 20, the overall size of the parts supply device 100 can be reduced, and as a result, the space for installing the parts supply device 100 becomes smaller, so that the degree of freedom of installation of the parts supply device 100 can be increased. In addition, since there is no need to provide a ramp between the funnel 50 and the tray 20, the manufacturing cost of the parts supply device 100 can be reduced.

[0070] In addition, in the above-mentioned embodiment, the height of the lower edge of the delivery port 53 of the funnel 50 is substantially the same as the height of the bottom surface 21 of the tray 20. In this way, by reducing the height difference of the portion through which the parts pass when moving from the funnel 50 to the tray 20, the impact on the parts when moving from the funnel 50 to the tray 20 can be reduced, and as a result, cracks or chips on the parts can be suppressed.

[0071] Next, modifications of the above-described embodiment will be described.

[0072] In the above embodiment, in order to make 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 21a formed on the bottom surface 21 of the tray 20. Even if the bottom side of the funnel 50 is not accommodated in the accommodation recess 21a, as long as 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 set to a predetermined size, for example, less than the maximum length of the part, the accommodation recess 21a may not be formed on the bottom surface 21 of the tray 20. In this case, the funnel 50 is placed on the bottom surface 21 of the tray 20 with the first gap G1 interposed between the bottom surface 21 of the tray 20 and the funnel 50.

[0073] In the above embodiment, the delivery passage 52 is formed in a straight line from the approximate center of the funnel 50 in the radial direction. Instead of this shape, the delivery passage 52 may be formed in a curved line from the approximate center of the funnel 50 toward the radially outer side. For example, by forming the delivery passage 52 in a curved line toward the carrying-in portion 28, the parts can be smoothly moved toward the conveying path 30.

[0074] In the above embodiment, a 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. Figure 5 As shown in the modified example, the second gap G2 may be replaced by an extension portion 52a extending radially outward from the portion provided with the storage recess 21a, formed on the lower edge side of the delivery port 53 of the funnel 50, so that the delivery passage 52 is extended radially outward, thereby making the lower edge of the delivery port 53 of the funnel 50 located above the bottom surface 21 of the disk 20. It should be noted that Figure 5 is a cross-sectional view showing a modified example, which is equivalent to Figure 3 . In this way, by forming a structure in which the delivery passage 52 overlaps with the bottom surface 21, it is possible to reliably prevent the parts from falling into 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 set to a predetermined size, for example, less than the maximum length of the parts, and the funnel 50 is set at the approximate center of the tray 20 in a state of not contacting the tray 20.

[0075] The structure, function, and effect of the embodiments of the present invention are described below.

[0076] The funnel 50 for supplying parts to the tray 20 that moves the brought-in parts by vibration comprises a storage section 51 for storing the parts, and a delivery outlet 53 for delivering the parts stored in the storage section 51. The funnel 50 is disposed on the bottom surface 21 of the tray 20 with a predetermined first gap G1 therebetween, and the parts are supplied to the bottom surface 21 through the delivery outlet 53.

[0077] In this structure, the hopper 50 is disposed on the bottom surface 21 of the tray 20 with a predetermined gap therebetween, and the 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 hopper 50 on the bottom surface 21 of the tray 20, the overall size of the parts supply device 100 can be reduced. In addition, as a result, the space for installing the parts supply device 100 is reduced, so the degree of freedom in the installation of the parts supply device 100 can be increased.

[0078] In addition, the height from the bottom surface 21 to the lower edge of the delivery port 53 is set to be less than the maximum length of the component.

[0079] In this structure, the height from the bottom surface 21 to the lower edge of the delivery port 53 is set to be less than the maximum length of the part. In this way, by limiting the height of the part falling when the part moves from the funnel 50 to the tray 20, the impact on the part during movement can be reduced. As a result, cracks or chips on the parts can be suppressed.

[0080] In addition, the lower edge of the delivery port 53 and the bottom surface 21 are on the same plane.

[0081] In this structure, the lower edge of the delivery port 53 is on the same plane as the bottom surface 21. In this way, by eliminating the height difference of the part passing through when the part moves from the funnel 50 to the tray 20, the impact received by the part during movement can be reduced. As a result, cracks or chips on the parts can be suppressed.

[0082] The hopper 50 also includes a hopper vibrator 60 that vibrates the storage section 51 . The hopper vibrator 60 vibrates the storage section 51 in a direction in which the delivery passage 52 extends from the storage section 51 to the delivery port 53 .

[0083] In this structure, the storage unit 51 is vibrated in the direction in which the delivery path 52 extends by the hopper vibrator 60, 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 unit 51 in the direction in which the delivery path 52 extends. In this way, by controlling the driving of the hopper vibrator 60, the parts can be supplied to the tray 20 as needed.

[0084] In addition, the parts supply device 100 includes: a funnel 50; a tray 20 having a transport path 30 formed along a circumferential direction, wherein the transport path 30 allows the transported parts to move by vibration; and a tray vibrator 10 that vibrates the tray 20, and a storage recess 21a is formed on the bottom surface 21 of the tray 20 for storing at least a portion of the funnel 50.

[0085] In this structure, a receiving recess 21a for receiving at least a part of the funnel 50 is formed on the bottom surface 21 of the tray 20. Thus, by receiving at least a part of the funnel 50 in the receiving recess 21a formed on the bottom surface 21 of the tray 20, the lower edge of the delivery port 53 of the funnel 50 can be made flush with the bottom surface 21 of the tray 20. As a result, the height difference of the part through which the part passes when moving from the funnel 50 to the tray 20 is reduced, and the impact received by the part when moving can be reduced, so that cracks or chips on the part can be suppressed.

[0086] In addition, the parts supply device 100 includes: a funnel 50; a tray 20, on which a conveying path 30 is formed along the circumferential direction, and the conveying path 30 allows the brought-in parts to move by vibration; and a tray vibrator 10, which vibrates the tray 20, and on the bottom surface 21 of the tray 20, a guide groove 21b is formed for guiding the parts delivered from the delivery port 53 to the conveying path 30.

[0087] In this structure, a guide groove 21b is formed on the bottom surface 21 of the tray 20 to guide the parts sent out from the delivery port 53 to the conveying path 30. In this way, by providing the guide groove 21b to guide the parts to the conveying path 30, it is possible to suppress the movement of the parts toward the delivery port 20a and the buffer 40, and by allowing the parts to move smoothly toward the conveying path 30, the parts aligned in a predetermined posture can be efficiently conveyed out of the delivery port 20a.

[0088] Although the embodiments of the present invention have been described above, the above embodiments are merely a part of application examples of the present invention, and the technical scope of the present invention is not limited to the specific structures of the above embodiments.
