DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, the configuration of the vibratory feeder according to the present invention will be described with reference to FIGS. 1 to 9. The vibratory feeder 1 of the present invention includes a housing portion 2, a conveying path (hereinafter referred to as the second conveying path 4) provided outside the housing portion 2, and a vibrating portion 3 that vibrates the housing portion 2 and the second conveying path 4. Due to the vibration from the vibration unit 3, the transport object 5 in the storage unit 2 gradually moves from the bottom center 6a side to the outer periphery, and then gradually moves along the first transport path 8 toward the first discharge opening 9. After reaching the first discharge opening 9, the transport object 5 loses balance and falls from the first discharge opening 9 into the second transport path 4 provided outside the storage unit 2. The clumped transport object 5 becomes unraveled and separated while falling, or due to the impact with the second transport path 4 after falling. The transport object 5 on the second transport path 4 then moves to the second discharge opening 11 due to the vibration from the vibration unit 3, and is discharged from the second discharge opening 11.

[0015] Vibration part 3 The vibration unit 3 is configured to torsionally vibrate the storage unit 2 with a predetermined amplitude. The storage unit 2 is fixed to the vibration unit 3 by inserting a bolt (not shown) through the bottom center 6a, and vibrates in the circumferential direction around the central axis with a predetermined period and a predetermined amplitude. The vibration is controlled by a control device (not shown). The vibrating unit 3 is a means for transmitting vibrations of a predetermined period to the storage unit 2 and the second conveying path 4, and various known vibrating devices for bowl-type vibrating feeders can be used as the vibration generating device. The vibrating means is not limited either, and any vibrating means employed in bowl-type vibrating feeders can be used, such as a vibrating means that converts vibrations via a displacement cam mechanism of an electromagnet, a piezoelectric element, a solenoid actuator, or a fluid pressure actuator. By vibrating the storage unit 2 by applying vibration from the vibration unit 3, the object 5 to be conveyed in the storage unit 2 moves in a fixed direction toward the first discharge port 9 and is carried out from the first discharge port 9. Similarly, by vibrating the second conveying path 4 by vibration from the vibration section 3, the object 5 to be conveyed in the second conveying path 4 moves in a fixed direction toward the second discharge outlet 11, specifically in the same direction as the object 5 to be conveyed in the storage section 2, and is discharged from the second discharge outlet 11.

[0016] Storage compartment 2 The container 2 has a bottom 6 , a wall 7 , and a first outlet 9 . The wall 7 is provided along the outer periphery of the bottom 6, and the object 5 to be conveyed is accommodated in the accommodating portion 2 formed by the bottom 6 and the wall 7. The height of the wall 7 can be set to any height, but it is preferably set to a height such that the object 5 bounced up by the vibration from the vibrating portion 3 does not go outside the accommodating portion 2 over the upper end portion of the wall 7. The first discharge port 9 is provided at a part of the outer periphery. The object 5 that has reached the first discharge port 9 due to the vibration from the vibrating portion 3 is discharged from the first discharge port 9 to the second conveyance path 4 provided outside the accommodating portion 2.

[0017] As a preferred embodiment of the accommodating portion 2, the bottom 6 of the accommodating portion 2 has the central portion 6a at the highest position, and is formed in a conical shape so as to incline downward from the central portion 6a outward, that is, in the direction of the wall 7. The inclination 6d (FIG. 6) is not particularly limited, and it is sufficient that the object 5 can move outward (in the outer peripheral direction) due to vibration. The accommodating portion 2 formed by the wall 7 provided along the outer periphery of the bottom 6 and the bottom 6 has a bowl shape, and the object 5 to be conveyed can be accommodated in the accommodating portion 2. The accommodating portion 2 may be a cylindrical bowl in which the wall 7 stands vertically, or may be a conical bowl in which the upper side of the wall 7 spreads outward. The bowl of an existing parts feeder can be used as the accommodating portion 2. The first discharge port 9 is provided at a part of the outer periphery, and is preferably provided on the wall 7. The installation height of the first discharge port 9 is not particularly limited, but when the first conveyance path 8 described later is provided, it is preferable that the first discharge port 9 is provided at a higher position than near the outer periphery of the bottom 6.

[0018] Preferably, a first conveyance path 8 is provided outside the accommodating portion 2, and is provided along the inner periphery of the wall 7 so as to be connected without interruption from the bottom 6 of the accommodating portion 2 to the first discharge port 9. The first conveyance path 8 is preferably provided so as to rise spirally along the inner periphery of the wall 7 from the bottom 6 to the first discharge port 9. The inclination of the spiral of the first conveyance path 8 may be such that the object 5 can move upward due to vibration. The gentler the inclination of the spiral, the easier it is for the object 5 to be moved toward the first discharge port 9 by vibration.

[0019] In addition, the first conveyance path 8 is formed in an inclined state where the side closer to the wall 7 of the accommodation part 2 is lower when viewed in the width direction (Fig. 6). By making the first conveyance path 8 inclined such that the side closer to the wall 7 is lower, the object 5 to be conveyed on the first conveyance path 8 moves toward the first discharge port 9 while being aligned in a substantially single row toward the wall 7 side due to vibration. The width of the first conveyance path 8 may be appropriately set according to the object 5 to be conveyed, and it is preferably set to a width such that the object 5 to be conveyed does not protrude from the first conveyance path 8. The inclination 8d (Fig. 6) in the width direction of the first conveyance path 8 is not particularly limited, and it is sufficient that the object 5 to be conveyed can move as described above.

[0020] Second conveyance path 4 A second conveyance path 4 is provided outside the accommodation part 2, and the bottom 4b of the second conveyance path 4 is provided at a position lower than the first discharge port 9 such that the object 5 to be conveyed discharged from the first discharge port 9 falls onto the bottom 4b of the second conveyance path 4. A wall 4c is provided along the outer periphery on the side opposite to the accommodation part 2 side at the bottom 4b of the second conveyance path 4. Furthermore, the bottom 4b is formed in an inclined state where the outer side (wall 4c side) is lower than the accommodation part 2 side (wall 7 side) (Fig. 7a). By inclining the second conveyance path 4 outward, the object 5 to be conveyed moves toward the second discharge port 11 while being aligned in a substantially single row in contact with the bottom 4b and the wall 4c due to the vibration from the vibration part 3.

[0021] The second conveyance path 4 is preferably provided outside the accommodation part 2, that is, along the outside of the wall 7. With this configuration, the object 5 to be conveyed transferred to the second conveyance part 4 can be moved toward the second discharge port 11 by utilizing the vibration from the vibration part 3. In this configuration, since the moving direction of the object 5 to be conveyed moving in the second conveyance path 4 is on the same direction side as the moving direction of the object 5 to be conveyed moving in the accommodation part 2, the second discharge port 11 needs to be provided on the downstream side in the moving direction.

[0022] The second conveyance path 4 provided outside the housing portion 2 is more preferably provided such that the end portion 4a on the housing portion 2 side of the second conveyance path 4 is in contact with the housing portion 2. When the end portion 4a on the housing portion 2 side of the second conveyance path 4 is in contact with the housing portion 2, the second conveyance path 4 can be vibrated together with the housing portion 2, and the conveyed object 5 discharged from the first discharge port 9 can be transferred without deviating outside the second conveyance path 4 system. In addition, if the vibration from the vibration portion 3 can be transmitted to the second conveyance path 4, the second conveyance path 4 may be provided in contact with a location other than the housing portion 2, for example, the outer periphery of the vibration portion 3.

[0023] The position of the second conveyance path 4 is provided at a position lower than the first discharge port 9. The conveyed object 5 discharged from the first discharge port 9 falls substantially vertically and moves to the second conveyance path 4. The lumps are separated by the impact during the fall. That is, the lump formed by combining a plurality of individuals is disassembled into individual conveyed objects 5 by the impact of the collision with the bottom portion 4b, and the lump is loosened. At this time, the higher the height from the bottom surface 4b of the second conveyance path 4 to the first discharge port 9, the greater the impact received by the lump when it falls and collides with the bottom surface of the second conveyance path 4, and the greater the disassembly effect of the lump. The height h (FIG. 7b) from the second conveyance path 4 to the first discharge port 9 may be set according to the type and size of the conveyed object 5 so as to obtain the disassembly effect of the above-mentioned lump. For example, the height h is preferably 2 times or more, more preferably 3 times or more, with respect to the size of the largest conveyed object 5 among the individual conveyed objects 5 that are not in the form of lumps. The upper limit of the height h varies depending on the conveyed object 5, but the height h may be set so that the conveyed object 5 does not bounce up and deviate outside the second conveyance path 4 after falling. For example, the height h is 5 times or less with respect to the size of the conveyed object 5. The size of the conveyed object 5 is the maximum length of the conveyed object 5 (hereinafter, sometimes referred to as the maximum diameter).

[0024] The bottom 4b of the second conveyance path 4 is formed in an inclined state such that, when viewed in the width direction, the outer side (the side opposite to the housing portion 2) is lower than the housing portion 2 side. Specifically, when viewed in the radial cross-section, the bottom 4b of the second conveyance path 4 is formed in an inclined state such that the outer side (the wall 4c side) is lower than the housing portion 2 side with respect to the horizontal plane (Fig. 7a). For example, the inclination 4d of the bottom 4b of the second conveyance path 4 is preferably 5° or more and 30° or less with respect to the horizontal. If the inclination 4d of the bottom 4b is too small, the agglomerated matter formed by meshing may not be decomposed, or even if it is decomposed, the plurality of objects 5 to be conveyed may not be aligned in a line in the traveling direction. If the inclination 4d of the bottom 4b is too large, the falling impact is mitigated and the agglomerated matter may not be decomposed, or even if it is decomposed, since the speed of sliding outside the second conveyance path 4 is high, it may combine with other objects 5 moving in the second conveyance path 4 to form a new agglomerated matter.

[0025] If the width of the second conveyance path 4, that is, the width from the wall 4c side of the second conveyance path 4 to the end portion 4a side of the housing portion 2 side is too narrow, the conveyed object 5 separated by falling may contact other conveyed objects 5 on the second conveyance path 4 and form a new agglomerated matter. Therefore, the width of the second conveyance path 4 is preferably widened according to the size of the conveyed object 5 so that such agglomerated matter cannot be formed. For example, it may be wider than the width of the first conveyance path 8. Alternatively, the width of the second conveyance path 4 may be, for example, preferably equal to or greater than the maximum diameter of the conveyed object 5, more preferably equal to or greater than 1.5 times the maximum diameter of the conveyed object 5, and preferably equal to or less than 4 times the maximum diameter of the conveyed object 5, more preferably equal to or less than 2 times the maximum diameter of the conveyed object 5.

[0026] When viewed in the longitudinal direction, the second conveyance path 4 may be horizontal from the first discharge port 9 side to the second discharge port 11, or may be inclined to either one side. In the illustrated example, the second conveyance path 4 is not provided with a gradient and is formed substantially horizontally from the start end to the end (Fig. 3). When the second conveyance path 4 is provided horizontally, the thrust for moving the conveyed object 5 can be small, so that the conveyed object 5 can be smoothly moved toward the second discharge port 11 as compared with the case where a gradient is provided.

[0027] The object 5 to be conveyed unloaded from the second row of outlets 11 may be supplied to another process, but it is preferable to further supply the object 5 to be conveyed unloaded from the second row of outlets to a discharge conveyance path (hereinafter referred to as the third conveyance path 12). When the unloaded object 5 to be conveyed is supplied to the third conveyance path 12, an appropriate interval can be provided between the objects 5 to be conveyed. The third conveyance path 12 is preferably a linear feeder that conveys the object 5 to be conveyed linearly. When a linear feeder is used for the third conveyance path 12, since the vibration direction required for the movement of the object 5 to be conveyed is different from that of the second conveyance path 4, it is preferable to provide a vibration unit 14 different from the vibration unit 3. The vibration unit 14 only needs to be able to apply vibration to move the object 5 to be conveyed in one direction, and a known vibration unit for a linear feeder can be adopted. Therefore, it is preferable that the vibration feeder 1 of the present invention further includes a third conveyance path 12 and a vibration unit 14 that vibrates the third conveyance path 12.

[0028] The longitudinal direction of the third conveyance path 12 is preferably provided in a direction intersecting the second row of outlets 11. By providing the third conveyance path 12 such that the movement direction 15b of the object 5 to be conveyed on the third conveyance path 12 intersects the movement direction 15a of the object 5 to be conveyed on the second row of outlets 11 in a direction intersecting on the same plane when viewed from above (Fig. 5b), the interval between the objects 5 to be conveyed supplied from the second row of outlets 11 can be maintained. When the longitudinal direction of the third conveyance path 12 is the same as the direction of the second row of outlets 11, that is, when the movement directions of the objects 5 to be conveyed are the same direction (both in the 15a direction), the object 5 to be conveyed supplied from the second row of outlets 11 may overlap with the objects 5 to be conveyed supplied before and after it and become a lump, or the interval between the objects 5 to be conveyed may not be maintained.

[0029] The bottom 12b of the third conveyance path 12 is preferably provided near the second row of outlets 11 so that the object 5 to be conveyed unloaded from the second row of outlets 11 is carried into the third conveyance path 12. Specifically, it is preferable to adjust the positional relationship between the third conveyance path 12 and the second row of outlets 11 so that the object 5 to be conveyed unloaded from the second row of outlets 11 does not deviate outside the third conveyance path 12.

[0030] The height h2 (Fig. 5a) of the bottom 12b of the third conveyance path 12 and the second discharge port 11 is not particularly limited, and a height difference may or may not be provided. If a height difference is provided, it can be decomposed when there are remaining lumps. When a height difference is provided, if the height h2 between the bottom 12b of the third conveyance path 12 and the third discharge port 13 is too high, the object 5 to be conveyed may bounce on the third conveyance path 12 and the objects 5 to be conveyed may overlap to form lumps. Therefore, it is preferably as low as possible that the height h2 between the bottom 12b of the third conveyance path 12 and the second discharge port 11. For example, it is preferable that the height h2 between the second discharge port 11 and the bottom 12b of the third conveyance path 12 is such that they do not come into contact with each other due to vibration. Also, it is preferable to arrange so that no gap is generated between the end of the second discharge port 11 and the third conveyance path 12 close to the end and the object 5 to be conveyed is not caught in the gap. For example, when viewed from above, the third conveyance path 12 (on the second discharge port 11 side) close to the end of the second discharge port 11 overlaps below the second discharge port 11 so that no gap is generated (Fig. 9a), and when viewed from the side (in the E direction of Fig. 9(a)), the height h2 is set so that the second discharge port 11 and the third conveyance path 12 do not come into contact with each other due to vibration (Fig. 9b).

[0031] Also, the bottom 12b of the third conveyance path 12 is preferably formed in an inclined state in which, when viewed in the radial cross-section, the bottom 12b of the third conveyance path 12 is lower on the outer side (wall 12c side) than on the second discharge port 11 side with respect to the horizontal plane (Fig. 8b). When the bottom 12b of the third conveyance path 12 is inclined, the object 5 to be conveyed discharged from the second discharge port 11 moves to the wall 12c side of the third conveyance path 12, so that overlap with other objects 5 to be conveyed discharged later can be suppressed. Also, while the third conveyance path 12 is inclined so that the outer side is lower, by providing the wall 12c along the outer side, the object 5 moves to the third discharge port 13 while being evenly arranged in a substantially single row in contact with the bottom 12b and the wall 12c due to the vibration from the vibration unit 14. The inclination 12d (Fig. 8b) in the width direction of the third conveyance path 12 may be set so as to obtain the above effects. For example, it is preferably 5° or more and 30° or less with respect to the horizontal.

[0032] Furthermore, the longitudinal direction of the third conveyance path 12 may be horizontal from the second discharge port 11 side, i.e., one end side, to the third discharge port 13 side, i.e., the other end side. However, it is preferably inclined such that the third discharge port 13 side has an upward slope (Fig. 8c). By setting the traveling direction of the object to be conveyed 5 as an upward slope, a space can be provided between the objects to be conveyed 5. The space (distance) between the objects to be conveyed 5 is not particularly limited, but it is a space where the front and rear objects to be conveyed 5 do not contact each other on the third conveyance path 12. More preferably, it is a space where the object to be conveyed 5 discharged from the third discharge port 13 to the next process does not contact the object to be conveyed 5 near the subsequent third discharge port 13. When another process to which the object to be conveyed 5 is supplied from the third discharge port 13 is a conveyance process such as a belt conveyor, if the moving speed of the object to be conveyed 5 supplied to the other process is slow, it may contact the subsequent object to be conveyed 5 supplied from the third discharge port 13. The upward slope angle 12e may be appropriately set so as to obtain the above effects. Preferably, it is more than 0°, more preferably 1° or more. Although it varies depending on the weight of the object to be conveyed 5, etc., if the upward slope angle 12e is too large, the moving speed may become too slow. Therefore, it is preferably less than 2°.

[0033] The length of the third conveyance path 12 is not particularly limited and may be appropriately adjusted in consideration of the installation space, the space between the front and rear objects to be conveyed 5, the supply speed, etc. As the length of the third conveyance path increases, the space between the front and rear objects to be conveyed 5 tends to become wider even at the same inclination angle. Therefore, as the length of the third conveyance path 12 increases, the supply speed of the object to be conveyed 5 per unit time also decreases.

[0034] Object to be conveyed 5 The object to be conveyed 5 does not constitute the device of the present invention but is described in the figure for convenience. Hereinafter, a suitable object to be conveyed 5 that is the processing target of the present invention will be described. Note that the object to be conveyed 5 is not limited to the following examples. The object to be conveyed 5 of the present invention may be either one having the same shape and size or one having different shapes and sizes from each other. When the shape of the object to be conveyed 5 is rod-shaped or perforated, it is likely to form a lump regardless of the specific type of the object to be conveyed 5. In particular, when objects to be conveyed 5 with different shapes and sizes are mixed, a plurality of objects to be conveyed 5 are likely to be combined by entanglement, embracing, fitting, etc. to form a lump. When the vibrating feeder of the present invention is used, the lump can be disassembled and separated into individual objects to be conveyed 5. The vibrating feeder 1 of the present invention may have a device configuration according to the size of the lump or the object to be conveyed 5.

[0035] The vibrating feeder 1 of the present invention can be used not only for parts used in the manufacturing processes of various industrial products, but also for various wastes as the object to be conveyed 5. Examples of the parts include fixtures such as screws, bolts, and nuts; electronic parts such as capacitors, coils, and resistors; other various product manufacturing parts; and manufacturing intermediate products. Examples of the wastes include valuable metal materials such as precious metals, iron, and non-ferrous metals; organic material such as rubber, plastic, and wood; and inorganic non-metallic materials such as glass, silicon, and ceramics. The waste may also be one that has been subjected to pretreatment such as dissolution, combustion, and physical separation. Specific examples of the waste include, in addition to the above parts, jewelry such as rings, and dental filling wastes.
