Summary of the Invention

Problems to be Solved by the Invention

[0006] Generally, parts supply devices handle a variety of parts, and these parts may have powder or oil adhering to them. In this case, the powder or oil adhering to the parts as they exit the transport path may adhere to the upper surface of the rotating disc. Furthermore, as the operating time of the parts supply device increases, dirt such as powder and oil accumulates on the upper surface of the rotating disc.

[0007] In the imaging device for the parts supply device described in Patent Document 1, the image processing device identifies the position and orientation of the parts in the aforementioned region on the upper surface of the rotating disk by image processing based on the contrast difference between the rotating disk and the parts. Therefore, as described above, if dirt such as powder or oil accumulates on the upper surface of the rotating disk due to the parts, it may become impossible to identify the position and orientation of the parts during image processing.

[0008] Therefore, the problem that this invention aims to solve is to provide a parts supply device that can remove dirt such as powder and oil accumulated on the upper surface of a rotating disk. [Means for solving the problem]

[0009] To solve the above problems, this invention comprises the following configurations 1 to 7. [Configuration 1] A vibrating bowl and A spiral conveying path extending upward is provided on the inner circumference of the bowl and conveys the parts inside the bowl by vibration, A rotating disc is provided around the bowl so as to rotate around the bowl, on which the parts that have come out of the transport path rest. A parts supply device comprising a transfer mechanism that identifies the position of a part on the rotating disk, picks up the part on the rotating disk, and transfers the picked-up part to a predetermined feeding position, A parts supply device characterized by comprising a cleaning unit for cleaning the upper surface of the rotating disk.

[0010] In this configuration, the cleaning unit removes dirt accumulated on the upper surface of the rotating disc. This cleans the upper surface of the rotating disc, which helps to suppress misrecognition of the part's pickup position by the transfer mechanism.

[0011] [Configuration 2] The parts supply device according to configuration 1, characterized in that, of the entire area of ​​the upper surface of the rotating disk on which the parts are placed, the cleaning area cleaned by the cleaning unit is located outside the parts transport area on the rotating disk, from the parts supply area to the parts recovery area.

[0012] With this configuration, the cleaning area is located outside the parts transport area, so the cleaning unit does not interfere with the pickup of parts from the rotating disc by the transport mechanism.

[0013] [Configuration 3] The cleaning unit comprises a support column provided on the outside of the rotating disc, and a cleaning head attached to the support column and positioned on the rotating disc. The parts supply device according to configuration 1 or 2, characterized in that a cleaning member is held in the cleaning head, and the cleaning member is in contact with the upper surface of the rotating disk.

[0014] With this configuration, when the cleaning area on the top surface of the rotating disk moves, such as when parts are changed or the position of the transfer mechanism is altered, the system can easily accommodate the change in the cleaning area's position by attaching a support column near the moved cleaning area.

[0015] [Structure 4] The parts supply device according to configuration 3, characterized in that the cleaning member is a sheet-like material, the sheet-like material is held in a state where it is wrapped around the cleaning head, and the sheet-like material is interposed between the cleaning head and the upper surface of the rotating disk.

[0016] With this configuration, the cleaning member is held wrapped around the cleaning head, so after cleaning, the cleaning member can be easily removed from the cleaning head and replaced.

[0017] [Configuration 5] The cleaning head has a pressing piece, and the pressing piece presses the sheet-like object against the cleaning head, and at least one of the cleaning head and the pressing piece has an anti-slip portion with respect to the sheet-like object. The component supply device according to Configuration 4, wherein the anti-slip portion is provided.

[0018] According to this configuration, by releasing the pressing of the cleaning head by the pressing piece, the cleaning member after cleaning can be peeled off from the cleaning head and easily replaced.

[0019] [Configuration 6] The cleaning member is a scraper, the scraper is held by the cleaning head, the scraper has a lower edge portion extending downward toward the upper surface of the rotating disk, and the lower edge portion of the scraper is in contact with the upper surface of the rotating disk. The component supply device according to Configuration 3, wherein the component supply device is characterized in that the component supply device is provided.

[0020] According to this configuration, the scraper can be easily replaced by removing the scraper from the cleaning head. Further, the scraper can be reused by cleaning the removed scraper.

The component supply device according to any one of Configurations 3 to 6, wherein the component supply device is characterized in that the component supply device is provided.

[0022] According to this configuration, the cleaning head is supported by the elastic member, and the elastic member can receive the weight of the cleaning head. Therefore, the force with which the cleaning head presses the upper surface of the rotating disk is reduced, and the cleaning head does not press the upper surface of the rotating disk more than necessary. Therefore, the cleaning head does not become a rotational resistance to the rotating disk and does not affect the conveyance of components. [Advantages of the Invention]

Mode for Carrying Out the Invention

[0025] The component supply device according to the present invention will be described based on FIGS. 1 to 6. This component supply device 1 includes a vibratory bowl feeder 4 having a vibrating bowl 2 and a spiral conveying path 3 provided on the inner peripheral portion of the bowl 2, a conveying table 6 having a rotating disk 5 that rotates around the bowl 2, and a cleaning unit 20 that cleans the upper surface of the rotating disk 5.

[0026] The vibrating bowl feeder 4 is equipped with a vibrator (not shown) that vibrates the bowl 2. The bowl 2 has a bottom 2a for accommodating parts W, and a conveying path 3 is provided that spirals upward from the outer diameter side of the bottom 2a. A parts discharge section 3a is formed at the top of the conveying path 3. Parts W contained in the bowl 2 move upward along the spiral conveying path 3 due to the vibration of the vibrator and are conveyed to the parts discharge section 3a at the top of the conveying path 3. In the following, "upstream" and "downstream" refer to the "upstream" and "downstream" directions of the conveying direction of parts W.

[0027] The attachment 7 is connected to the part discharge section 3a of bowl 2. The attachment 7 is formed along the outer circumference of bowl 2 and has a width dimension approximately the same as the width dimension of the transport path 3 (the width dimension of the part on which the parts W are placed). The parts W discharged from the part discharge section 3a are aligned in the same orientation by the attachment 7.

[0028] A guide plate 8 is connected to the downstream end of attachment 7. The guide plate 8 is fixed to the bowl 2. The part W discharged from the downstream end of attachment 7 is guided by the guide plate 8 towards the radial center of the rotating disc 5. The guide plate 8 guides the part W without changing its orientation.

[0029] The transport platform 6 is arranged in a ring shape around the bowl 2 of the vibrating bowl feeder 4. The transport platform 6 is installed on the same base plate 9 as the vibrating bowl feeder 4. The transport platform 6 comprises a rotating disc 5 that rotates around the bowl 2, a rotational drive device (not shown) that rotates the rotating disc 5, and a cylindrical outer wall plate 10 provided around the rotating disc 5.

[0030] The rotating disc 5 is positioned slightly lower than the downstream end of the guide plate 8 of the vibrating bowl feeder 4. The parts W discharged from the downstream end of the guide plate 8 will land on the upper surface of the rotating disc 5 in the same orientation. The upper surface of the rotating disc 5 constitutes the conveying surface 5a. As shown in Figure 1, the upper edge of the outer wall plate 10 is positioned slightly higher than the rotating disc 5.

[0031] The conveying surface 5a of the rotating disk 5 is provided with a parts supply area 11, a sensing area 12, a pickup area 13, a parts recovery area 14, and a cleaning area 15, arranged in the circumferential direction. The parts supply area 11 is the area where parts W are supplied from the parts discharge section 3a. The sensing area 12 is located downstream of the parts supply area 11 in the flow direction of parts W. In the sensing area 12, the position and orientation of parts W are detected by a parts detection means 16, which will be described later. The pickup area 13 is located downstream of the sensing area 12 in the flow direction of parts W. In the pickup area 13, parts W are picked up by a transfer mechanism 17, which will be described later.

[0032] The parts recovery area 14 is located downstream of the parts W in the flow direction from the pickup area 13. In the parts recovery area 14, parts W that were not picked up in the pickup area 13 are returned to the bowl 2 by the transfer mechanism 17. Parts W are returned to the bowl 2 from the transport path 3 via the parts recovery unit located in the parts recovery area 14. The area from the parts supply area 11 to the parts recovery area 14 is the parts transport area where parts W are transported. In this embodiment, the parts recovery unit is an opening 2b that penetrates the bowl 2. The cleaning area 15 is located downstream of the parts recovery area 14 in the flow direction from the parts W. A cleaning unit 20 is located in the cleaning area 15. The cleaning area 15 only needs to be located outside the parts transport area of ​​the entire upper surface of the rotating disk 5 on which the parts W are placed.

[0033] The part detection means 16 is, for example, an imaging device such as a camera. This imaging device identifies the position and orientation of the part W by image processing based on the contrast between the part W sent to the sensing area 12 and the transport surface 5a, and detects the part W that can be picked up in the pickup area 13.

[0034] As shown in Figures 1 and 2, the transfer mechanism 17 is a robot arm comprising an arm 17a and a hand 17b provided at the tip of the arm 17a. In the pickup area 13, the transfer mechanism 17 drives the arm 17a and hand 17b to pick up the pickable parts W detected by the part detection means 16 from the transport surface 5a one by one, and transfers the picked-up parts W to a predetermined feed position (not shown) for the next process. The transfer mechanism 17 may also include the part detection means 16.

[0035] As shown in Figure 3, the cleaning unit 20 includes a support column 21, a holder 22 attached to the upper part of the support column 21, and a cleaning head 23 held by the holder 22. As shown in Figure 1, the support column 21 is fixed to the base plate 9 in a state that extends upward. The support column 21 is a rod-shaped member with a circular cross-section and is located radially outward of the cleaning area 15 of the rotating disc 5 of the transport table 6.

[0036] The holder 22 has an annular retainer 24 that tightens around the support column 21 and a frame 25 fixed to the retainer 24. The retainer 24 has radially spaced notches 24a. The retainer 24 has bolts 26 that move its circumferential ends closer together or further apart. The bolts 26 pass through one end of the circumferential ends of the retainer 24 and screw-connect to a female thread 24b provided at the other end. When the retainer 24 is inserted through the support column 21 and the bolts 26 are tightened into the female thread 24b, the distance between the notches 24a decreases. As a result, the retainer 24 tightens around the support column 21 at its inner circumference and is held in place by the support column 21. When the bolts 26 are removed from the female thread 24b, the retainer 24 becomes movable vertically along the support column 21.

[0037] The frame 25 has a lower plate portion 25a located below the holder 24, a pair of side plate portions 25b fixed to both sides of the lower plate portion 25a in the width direction (direction perpendicular to the support column 21), and an upper plate portion 25c connecting the upper ends of the pair of side plate portions 25b. The lower plate portion 25a has bifurcated portions 25d that fit into both sides of the support column 21 in the diameter direction, and the bifurcated portions 25d and the holder 24 are fixed by bolts 27 that are screwed in upward from below.

[0038] As shown in Figure 4, the pair of side plate sections 25b are arranged parallel to each other in the vertical direction. Elongated holes 25e are provided in the upper part of the pair of side plate sections 25b, running vertically. A wing bolt 28 is inserted through each elongated hole 25e, and the wing bolt 28 is screw-connected to the base plate 29 of the cleaning head 23, which will be described later.

[0039] The cleaning head 23 has a base plate 29, a retaining piece 30 attached to the upper part of the base plate 29, and an anti-slip part 31 fixed to the lower part of the base plate 29. The base plate 29 is a strip-shaped member. The base plate 29 has the same width dimension as the distance between the pair of side plate portions 25b of the holder 22. A through hole 29a is provided at one end of the base plate 29 in the longitudinal direction. A support column 21 is inserted through the through hole 29a. Two wing bolts 28 are screw-connected to the base plate 29 near one end, facing inward in the width direction of the base plate 29. When the base plate 29 moves in the vertical direction, the wing bolts 28 move vertically along the elongated holes 25e of the side plate portion 25b of the holder 22, guiding the vertical movement of the base plate 29.

[0040] A hook 32 is attached to the other end of the substrate 29 in the longitudinal direction. The hook 32 is integrally provided with a rotating shaft 32a that penetrates the other end of the substrate 29 along the width direction and a hook portion 32b that extends in a direction perpendicular to the rotating shaft 32a. A notch 29b is formed in the center of the width direction of the other end of the substrate 29, in which the rotating shaft 32a is exposed. In the notch 29b, the hook portion 32b rotates up and down about the rotating shaft 32a and swings.

[0041] The retaining piece 30 has a retaining portion 30a and a hook receiving portion 30b that are fixed to the lower surface. As shown in Figure 5, the retaining piece 30 is formed with a width smaller than the width dimension of the substrate 29. A window portion 30c is provided along the length direction of the retaining piece 30. The retaining portion 30a is a strip-shaped member and has a width smaller than that of the retaining piece 30. Both ends of the retaining portion 30a in the length direction are formed with a thinner wall thickness than the middle portion in the length direction. Both ends of the retaining portion 30a in the length direction are fixed to the retaining piece 30 by screw connection of male screws.

[0042] The hook receiving portion 30b is fixed to the retaining piece 30 on the opposite side of the support column 21 by a screw connection with an external screw. As shown in Figure 6, the hook receiving portion 30b is a plate-shaped member having a bifurcated portion at its tip (the tip on the other end side of the base plate 29). The retaining piece 30 is attached to the base plate 29 so as to be able to open and close vertically via a hinge portion 30d. The hinge portion 30d is located on the opposite side of the support column 21, sandwiching the upper plate portion 25c of the holder 22. When the retaining piece 30 is closed downwards, the hook portion 32b of the hook 32 can be hooked onto the bifurcated portion of the hook receiving portion 30b.

[0043] The anti-slip portion 31 is a strip-shaped member with a width smaller than that of the substrate 29. The anti-slip portion 31 has a length that extends from one end of the substrate 29 to the vicinity of the pair of side plates of the holder 22. The anti-slip portion 31 is fixed along the length of the central part of the substrate 29 in the width direction. Synthetic rubber such as chloroprene rubber, urethane rubber, or nitrile rubber can be used as the material for the anti-slip portion 31.

[0044] Furthermore, the cleaning head 23 has a coil spring 33 as an elastic member that is inserted through the support column 21 and held on the holder 24. The coil spring 33 supports the base plate 29 of the cleaning head 23. Also, as shown in Figure 5, the cleaning head 23 has a cleaning member 40 that is held in a state where it is wrapped around the base plate 29. The cleaning member 40 is a sheet-like material and can be, for example, a rag made of nonwoven fabric of natural or synthetic fibers, or a sponge made of natural material or synthetic resin.

[0045] As shown in Figure 6, the cleaning member 40 is wrapped around the substrate 29 and the anti-slip portion 31 with the pressing piece 30 open upward relative to the substrate 29 (see Figure 5). The cleaning member 40 is pressed against the upper surface of the substrate 29 by the pressing portion 30a, which engages the hook portion 32b of the hook 32 of the substrate 29 with the hook receiving portion 30b of the pressing piece 30. This pressing holds the cleaning member 40 in place on the cleaning head 23. As shown in Figures 1 and 2, the cleaning head 23 is placed on the transport surface 5a in the cleaning area 15 of the rotating disc 5, so that the cleaning member 40 is interposed between the anti-slip portion 31 and the transport surface 5a in the cleaning area 15.

[0046] The parts supply device 1 according to this embodiment of the invention has the above-described configuration. In the parts supply device 1 of this embodiment, the cleaning member 40 of the cleaning unit 20 can wipe away dirt such as powder and oil accumulated on the conveying surface 5a of the rotating disk 5 in the cleaning area 15 of the rotating disk 5, thereby cleaning the conveying surface 5a. By cleaning the conveying surface 5a, false detection of parts W by the parts detection means 16 in the sensing area 12 of the rotating disk 5 can be suppressed.

[0047] In the parts supply device 1, the cleaning area 15 is located outside the parts transport area from the parts supply area 11 to the parts recovery area 14, out of the entire area of ​​the upper surface of the rotating disk 5 of the transport table 6. Therefore, the upper surface of the rotating disk 5 can be cleaned without interfering with the pickup of parts W by the transfer mechanism 17 in the pickup area 13 and the recovery of parts W in the parts recovery area 14.

[0048] The cleaning unit 20 of the parts supply device 1 includes a support column 21, a holder 22 attached to the support column 21, and a cleaning head 23 attached to the holder 22. Therefore, when the position of the cleaning area 15 on the upper surface of the rotating disc 5 of the transport table 6 moves, such as when the parts W are changed or the position of the transport mechanism 17 is changed, the cleaning unit 20 can easily respond to the movement of the cleaning area 15 by attaching the support column 21 near the moved cleaning area.

[0049] Furthermore, the cleaning member 40 of the cleaning unit 20 is a sheet-like material, and is wrapped around the cleaning head 23 while being pressed against the substrate 29 by the retaining piece 30. Therefore, by releasing the pressure on the substrate 29 by the retaining piece 30, the cleaning member 40 can be easily replaced from the cleaning head 23 after cleaning.

[0050] Furthermore, in the cleaning unit 20, a coil spring 33 is inserted through the support column 21, and the coil spring 33 is held on a holder 24 fixed to the support column 21. In addition, the substrate 29 of the cleaning head 23 is supported by the coil spring 33, and the coil spring 33 bears the weight of the cleaning head 23. As a result, the force with which the substrate 29 presses against the transport surface 5a of the rotating disk 5 is reduced, and the substrate 29 does not press against the transport surface 5a of the rotating disk 5 more than necessary. Therefore, the substrate 29 does not become a rotational resistance to the rotating disk 5 and does not affect the transport of the parts W.

[0051] Furthermore, when the rotating disc 5 rotates, the transport surface 5a may be slightly displaced in the vertical direction. In this case, the substrate 29 of the cleaning head 23 can move vertically relative to the support column 21 to accommodate the vertical displacement of the transport surface 5a.

[0052] In this embodiment of the parts supply device 1, an example was described in which the cleaning member of the cleaning unit 20 is a sheet-like material. However, as shown in Figures 7 and 8, for example, a configuration can also be adopted in which the cleaning member is a scraper 41 held by the cleaning head 23.

[0053] As shown in Figure 7, the scraper 41 as a cleaning member has a flat plate portion 41a that rests on the substrate 29 of the cleaning head 23, a bent surface portion 41b of the flat plate portion 41a that bends downward from one side edge of the substrate 29 in the width direction, and an inclined surface portion 41c of the flat plate portion 41a that slopes downward from the other side edge of the substrate 29 in the width direction, moving away from the other side of the substrate 29 in the width direction. As the material of the scraper 41, hard rubber such as chloroprene rubber or urethane rubber can be used.

[0054] As shown in Figure 8, the scraper 41 is positioned such that the bent surface portion 41b is aligned with one end face in the width direction of the substrate 29, and the inclined surface portion 41c protrudes from the other end face in the width direction of the substrate 29, with the flat plate portion 41a being pressed against the substrate 29 by the retaining piece 30. Furthermore, the inclined surface portion 41c is inclined downward toward the downstream side of the substrate 29, and the lower edge of the inclined surface portion 41c makes linear contact with the transport surface 5a in the cleaning area 15 of the rotating disc 5. As a result, the scraper 41 scrapes off dirt from the transport surface 5a in the cleaning area 15, cleaning the transport surface 5a.

[0055] Furthermore, by releasing the pressure on the substrate 29 by the retaining piece 30, the scraper 41 can be easily replaced from the cleaning head 23 after cleaning. In addition, the scraper 41 can be reused after cleaning by washing it. [Explanation of symbols]
