Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when handling short articles with a device such as that of Patent Document 1, the articles easily rotate on the outer rotating body, so it is difficult for the longitudinal direction of the articles to follow the longitudinal direction of the slit, and there are cases where the overhanging portion cannot be engaged with the slit to achieve a standing posture, resulting in a decrease in alignment efficiency.

[0005] An object of the present invention is to improve the alignment efficiency of short articles provided with overhanging portions.

Means for Solving the Problems

[0006] The first invention of the present invention is an article orientation alignment device comprising: an annular outer rotating body that rotates around a rotation axis aligned with the vertical direction, having a plurality of slits on its outer circumference having open ends that are open to the outside; an inner rotating body that is positioned inside the outer rotating body and to which articles are supplied, and rotates around a rotation axis inclined with respect to the vertical direction; and a discharge means provided at the end of the transport path of the outer rotating body for discharging articles transported by the outer rotating body, wherein the articles supplied by the inner rotating body are transferred to the upstream part of the transport path of the outer rotating body, the articles transferred onto the slits on the outer rotating body are transported downstream, and the articles are discharged from the outer rotating body to the discharge means via the open ends of the slits, wherein the articles have protruding portions that extend along a plane intersecting the axis of the article, and extending from the protruding portions along the axis The outer rotating body has a protruding portion that is smaller in diameter than the overhang, the width of the slit is set to allow the passage of the protruding portion and restrict the passage of the overhang, the longitudinal direction of the slit is arranged to be along the radial direction of the outer rotating body, and the transport path of the outer rotating body is characterized by having a first section in which a fixed plate is provided below the outer rotating body adjacent to the slit, a second section provided downstream of the first section of the transport path in which no fixed plate is provided below the outer rotating body adjacent to the slit, a third section provided downstream of the second section of the transport path in which a fixed plate is provided below the outer rotating body adjacent to the slit, and a fourth section provided downstream of the third section of the transport path in which no fixed plate is provided below the outer rotating body adjacent to the slit.

[Effects of the Invention]

[0008] According to the present invention, the alignment efficiency of short articles provided with protruding portions can be improved. [Brief explanation of the drawing]

[Figure 11] This is an enlarged cross-sectional view of the vicinity of the annular portion showing the state of an article in the third section of the second embodiment, where the shaft is lying on its side along the slit. [Modes for carrying out the invention]

[0010] Embodiments of the present invention will be described below with reference to the drawings. Figure 1 is a plan view of an article orientation alignment device, which is a first embodiment of the present invention, and Figure 2 is a cross-sectional view of Figure 1, AA.

[0011] The article orientation device 10 of the first embodiment is used for oriented alignment of a short article M having an overhanging portion that extends along a plane intersecting the axis, and a projection that extends from the overhanging portion along the axis and has a smaller diameter than the overhanging portion. The article M is, for example, a lid that also serves as a measuring cup used for a container filled with liquid detergent or the like.

[0012] The article orientation alignment device 10 comprises an inner rotating body 12 whose rotation axis L1 is tilted at a predetermined angle from the vertical, and an annular outer rotating body 14 that is horizontally arranged around the inner rotating body 12 and rotates around a vertical axis L2. The inner rotating body 12 is tilted in a direction substantially along line AA in Figure 1, and as shown in Figure 2, the outer rotating body 14 is positioned at the same height as the highest position P (upstream part) of the inner rotating body 12.

[0013] Above the inner rotating body 12, a hopper 16 for randomly loading the article M near the central portion of the inner rotating body 12 and a residual amount detection sensor for detecting the article M remaining on the inner rotating body 12 are arranged. The lower surface of the inner rotating body 12 is supported by a shaft 12A, and the inner rotating body 12 is rotated at a predetermined speed around the rotation axis L1 by an inner rotating body drive motor 12B.

[0014] The outer rotating body 14 includes an annular ring portion 14A, a bowl-shaped support portion 14B extending downward in a bowl shape from the inner peripheral edge of the ring portion 14A, and a cylindrical support portion 14C extending downward from the bottom of the bowl-shaped support portion 14B. The lower portion of the cylindrical support portion 14C is pivotally supported on a shaft 18 via a bearing 18A. Thereby, the outer rotating body 14 is rotatable about a rotation axis L2 that coincides with the central axis of the shaft 18.

[0015] An annular gear 14D is disposed at the bottom of the bowl-shaped support portion 14B around the rotation axis L2, and the gear 14D engages with a drive gear 20A attached to an outer rotating body drive motor 20 that rotates around a vertical axis. That is, the outer rotating body 14 rotates around the rotation axis L2 by the rotation of the outer rotating body drive motor 20. Note that the inner rotating body 12 and the outer rotating body 14 of the present embodiment rotate in the same direction (counterclockwise in FIG. 1), and the inner rotating body 12 rotates at a slightly higher speed than the outer rotating body 14.

[0016] On the outer peripheral portion of the upper surface of the inner rotating body 12, lifting bars 22 for lifting the article M along the radial direction are arranged at predetermined intervals. On the other hand, in the ring portion 14A of the outer rotating body 14, slits 24 that are open outward along the radial direction are arranged at regular intervals in the circumferential direction. The width of the slit 24 is set to be wider than the outer diameter of the protruding portion of the article M and narrower than the outer diameter of the overhanging portion.

[0017] Below the annular portion 14A, an arc-shaped fixed frame 26 is arranged in a section from approximately 3 o'clock to 1 o'clock along the circumferential direction of the annular portion 14A. On the fixed frame 26, fixed plates 26A, 26B, and 26C are attached at different heights and inclinations between the fixed frame 26 and the lower surface of the annular portion 14A, and are used for correcting the posture of the article M in the annular portion 14A as will be described later.

[0018] In the present embodiment, as shown in FIG. 1, the fixed plate 26A is horizontally arranged at a height adjacent to the lower surface (or slit 24) of the annular portion 14A at two locations in a section from approximately 11 o'clock to 1 o'clock (first section) S1 and a section from approximately 6 o'clock to 9 o'clock (third section) S4. Further, in a section from approximately 9:30 to 11 o'clock (second section) S2 and a section from approximately 3 o'clock to 6 o'clock (fourth section) S5, the fixed plate 26B is horizontally arranged at a position lower than the fixed plate 26A, that is, at a height where a protruding portion of the article M supported by the slit 24 does not engage (a height not adjacent to the lower surface (or slit 24) of the annular portion 14A), and the lower part of the slit 24 is open. Between the section S2 and the section S4, a slope-shaped fixed plate 26C connecting the fixed plate 26B in the section S2 and the fixed plate 26A in the section S4 is arranged. The width of the fixed plate 26A substantially corresponds to the length of the slit 24 and has a width capable of closing the slit 24 from below over the entire longitudinal direction of the slit 24. Also, the fixed plate 26B can be omitted.

[0019] Just above the annular portion 14A, an outer guide 28A for guiding the movement of the article M by the annular portion 14A is arranged in a section from approximately 3 o'clock to 12 o'clock along the outer peripheral edge of the annular portion 14A, and an inner guide 28B paired with the outer guide 28A is arranged in a section from approximately 3 o'clock to 5 o'clock along the inner end of the slit 24 of the annular portion 14A. Further, from a position approximately at 3 o'clock (downstream portion) below the annular portion 14A, a discharge chute (discharge means) 30 for discharging the articles M aligned in direction in the annular portion 14A extends in a tangential direction so as to be connected to the section S5.

[0020] Furthermore, above the annular portion 14A, multiple air nozzles are arranged radially toward the annular portion 14A on both the inside and outside of the annular portion 14A. In this embodiment, a transfer air nozzle 32 is positioned at the 12 o'clock position (position P), inside the scraping bar 22, to move the article M on the inner rotating body 12, which has been scraped up by the scraping bar 22, toward the annular portion 14A of the outer rotating body 14, diagonally downward and radially outward.

[0021] Furthermore, in sections S1 and S4 where the fixing plate 26A is provided, a pair of rotating air nozzles 34A and 34B are provided to rotate the orientation of the article M on the annular section 14A. Rotating air nozzle 34A is positioned inside the annular section 14A with its nozzle facing outwards, and rotating air nozzle 34B is positioned outside the annular section 14A with its nozzle facing inwards. The rotating air nozzles 34A and 34B are positioned slightly offset in the circumferential direction of the annular section 14A (in the example in Figure 1, the inner rotating air nozzle 34A is positioned upstream, and the outer rotating air nozzle 34B is positioned slightly downstream). In section S1 of this embodiment, a pair of rotating air nozzles 34A and 34B are provided between 11 o'clock and 12 o'clock, and in section S4, a pair of rotating air nozzles 34A and 34B are provided at two locations, between 8 o'clock and 9 o'clock, and around 7 o'clock.

[0022] Furthermore, in sections S2 and S5 where a fixed plate 26B is provided at a low position (or where no fixed plate is provided), a sorting air nozzle 36 is provided to blow air off articles M whose orientation has not been corrected on the annular section 14A from the outside of the annular section 14A toward the inner rotating body 12. In this embodiment, it is positioned near the 10 o'clock position in section S2 and near the 5:30 position in section S5. Also, downstream of the sorting air nozzle 36 in section S5 and upstream of the inner guide 28B, an outward-pushing air nozzle 38 is provided to push air off articles M whose orientation has been corrected by fitting into the slit 24 toward the outer guide 28A from the inside of the annular section 14A. Articles M that have been moved within the slit 24 by the outward-pushing air nozzle 38 while maintaining their orientation until they contact the outer guide 28A are guided by the outer guide 28A and the inner guide 28B and transported to the discharge chute 30.

[0023] Figure 3 is a side view illustrating four types of articles M1, M2, M3, and M4 handled by the article orientation alignment device 10 of this embodiment. Each of the articles M1 to M4 has an overhanging portion that extends along a plane intersecting the axis, and a projection that extends from the overhanging portion along the axis and has a smaller diameter than the overhanging portion. In Figure 3, the overhanging portions of each article M1 to M4 are engaged with the upper surface of the annular portion 14A, and the projections are shown in an upright position (aligned orientation) with the projections suspended downward from the slit 24.

[0024] The article M, which is fed from the hopper 16 to a point slightly below the center of the inclined inner rotating body 12, rolls along the inclined surface of the inner rotating body 12, moves in the 6 o'clock direction in Figure 1 (left side in Figure 2), and accumulates along the inner circumferential surface of the bowl-shaped support portion 14B. The article M is scraped up by the scraping bars 22 provided on the outer circumference of the inner rotating body 12, and is pushed onto the annular portion 14A of section S1 by centrifugal force and air from the transfer air nozzle 32 near the 12 o'clock position in Figure 1 (near position P), where the outer edge of the inner rotating body 12 is highest.

[0025] Figures 4 to 6 are enlarged cross-sectional views of the vicinity of the annular section 14A, showing the various orientations of article M in the annular section 14A of sections S1 and S4. In the drawings from Figure 4 onward, article M1 is shown as a representative example.

[0026] Figure 4 shows the state in which the article M1 is fitted into the slit 24 in an upright position (aligned to the desired orientation). That is, the protruding portion of the article M1 is fitted into the slit 24, the tip of the protruding portion is supported by the fixing plate 26A, and the overhanging portion of the article M1 is slightly raised from the annular portion 14A. The article M1 fitted into the slit 24 is transported with the protruding portion sliding along the fixing plate 26A, and as the article M1 moves to section S2 or section S5, the fixing plate 26B moves away from the protruding portion of the article M1, and the article M1 descends within the slit 24 while maintaining its upright position, and the overhanging portion of the article M1 is supported by the upper surface of the annular portion 14A. As a result, each article M1 is supported in an upright position by each slit 24 of the annular portion 14A, as shown in Figure 7. Furthermore, in section S2, the item M1, which is in the state shown in Figure 7, is lifted while maintaining its posture by the protrusion engaging with the slope-shaped fixing plate 26C in section S3, and returns to the state shown in Figure 4 in section S4.

[0027] The sorting air nozzles 36 provided in sections S2 and S5 are positioned approximately horizontally at a position slightly higher than the top surface of the article M1, which is supported by the slit 24 of the annular section 14A in an upright position, as shown in Figure 7, and spray air from the outside to the inside of the annular section 14A. When the article M1 is not fitted into the slit 24 in an upright position (positions such as those in Figures 5 and 6), air from the sorting air nozzles 36 is blown onto the article M1, causing the article M1 to fall from the annular section 14A onto the inner rotating body 12 in the bowl-shaped support section 14B. As a result, the article M1 that is not aligned in the correct orientation is returned to the inner rotating body 12 and is again scraped up by the scraping bar 22.

[0028] Figure 5 shows the state of article M1 lying on its side on the slit 24 of the annular portion 14A, with the axis of article M1 positioned along the radial direction of the annular portion 14A. In Figure 5, the protruding portion of article M1 is located on the slit 24, and when article M1 is moved to sections S2 and S5, article M1 rotates by its own weight around the protruding portions that engage with the annular portion 14A on both sides of the slit 24, and the protruding portion fits into the slit 24, resulting in the state shown in Figure 7.

[0029] Figure 6 shows the state of article M1 lying on its side on the annular portion 14A, with its axis positioned so as to intersect the radial direction of the annular portion 14A. In this position, some protruding or overhanging parts of article M1 may extend downward from the slit 24. However, in this case, such parts are supported by the fixing plate 26A, and no part of article M1 becomes trapped in the slit 24, preventing its orientation from being corrected. When article M1 in the position shown in Figure 6 is transported between the rotating air nozzles 34A and 34B, article M1 is easily rotated by the air from the rotating air nozzles 34A and 34B to the state shown in Figure 5. Then, while maintaining the state shown in Figure 5, article M1 is moved to sections S2 and S5, and as explained with reference to Figure 5, article M1 is moved to the state shown in Figure 7 by its own weight. The article M1, in the state shown in Figure 7, is moved within the slit 24 by the external air nozzle 38 until it contacts the outer guide 28A, and then, while maintaining the same orientation, is transferred to the discharge chute 30 at the 3 o'clock position in Figure 1. As a result, the articles M1, all facing the same direction, are aligned in the discharge chute 30 and transported downstream via the discharge chute 30.

[0030] As described above, in the article orientation alignment device of the first embodiment, the article M transferred to the annular portion 14A of the outer rotating body is aligned twice, once in sections S1 and S2, and again in sections S4 and S5. Therefore, alignment efficiency can be improved even when handling short articles with flanges.

[0031] Next, with reference to Figures 8 to 11, the article orientation alignment device of the second embodiment will be described.

[0032] The configuration of the article orientation alignment device 40 in the second embodiment is substantially the same as that of the article orientation alignment device 10 in the first embodiment. However, in the article orientation alignment device 40 of the second embodiment, the article M, which is in the correct orientation as shown in Figure 7 in section S2, is configured to maintain that orientation in section S4 and not to engage with the fixing plate 26A again. That is, in the second embodiment, the fixing plate 26A in section S4 and the slope-shaped fixing plate 26C in section S3 of the first embodiment are configured as fixing plates 42 and 44 with approximately half the width from the inside, and in section S2, an outward-facing air nozzle (gas injection means) 46 is provided between the annular section 14A and the fixing plate 26B, directed from the inside to the outside of the annular section 14A. The other configurations are the same as in the first embodiment, and the same reference numerals are used for the same configurations as in the first embodiment, and their explanations are omitted.

[0033] Figure 9 is an enlarged cross-sectional view of the vicinity of the annular portion 14A, showing the state of the article M1 supported by each slit 24 of the annular portion 14A in an upright position in section S2. As shown in Figure 9, an outward-facing air nozzle 46 is positioned radially outward from near the outer circumference of the bowl-shaped support portion 14B just below the lower surface of the annular portion 14A in section S2. Air from the outward-facing air nozzle 46 is blown onto the protruding portion of the upright article M1 that protrudes (hangs down) downward from the slit 24 in section S2, and the article M1 is moved along the slit 24 until it contacts the outer guide 28A. Note that an article M1 that is not in an upright position in section S2 will not be moved outward along the slit 24 by the air from the outward-facing air nozzle 46 because its protruding portion does not protrude sufficiently downward from the slit 24.

[0034] Figure 10 is an enlarged cross-sectional view near the annular portion 14A showing the state of article M1 in section S4 where it is lying on its side and its axis intersects the radial direction of the annular portion 14A (not in an upright position). Figure 11 is an enlarged cross-sectional view near the annular portion 14A showing the state in section S4 where article M1 is held in an upright position in the slit 24. As shown in Figures 10 and 11, the fixing plate 42 provided in section S4 is only about half the width of the inner fixing plate 26A shown in Figures 4 to 6, and no fixing plate 42 is provided below the outside of the slit 24. Also, the slope-shaped fixing plate 44 provided in section S3 is the same as the fixing plate 42, with a width of half the width of the inner fixing plate 26C, and connects the fixing plate 26B in section S2 and the fixing plate 42 in section S3.

[0035] In section S1, similar to Figures 4 to 6 of the first embodiment, the orientation of the article M1 on the annular section 14A is corrected by contact with the rotating air nozzles 34A and 34B and the slit 24, and part (or all) of it is conveyed upright as shown in Figure 4, with the lower end of the protruding portion sliding in contact with the fixed plate 26A. When the fixed plate 44 moves away from the protruding portion of the article M1 in section S2, the upright article M1 is conveyed in an upright position, as shown in Figure 7, with the overhanging portion supported by both edges of the slit 24 and the protruding portion hanging down below the slit 24. These articles M1 are then pressed against the outer guide 28A by air from the outward-guiding air nozzle 46, as shown in Figure 9. The article M1 in the state shown in Figure 9 is then conveyed in section S4 without engaging with the fixed plate 44 in section S3 or the fixed plate 42 in section S4, with the outside of the fixed plate 42 sliding in contact with the outer guide 28A, as shown in Figure 11.

[0036] On the other hand, the article M1 that was not upright in section S1 is transported in a lying position through section S2, and when it is transported to section S4, it remains lying on its side as shown in Figure 10. In section S4, similar to section S1, the orientation of part (or all) of the article is corrected and it is upright by contact with the rotating air nozzles 34A, 34B and the slit 24. The lower end of the protruding part of the upright article M1 is transported while sliding in contact with the fixed plate 42 adjacent to the annular part 14A.

[0037] When the article M1, which has been upright in section S4, reaches section S5 and the fixing plate 26B moves away from the protruding portion, the article M1 is transported in an upright position, as shown in Figure 7, with the overhanging portion supported by both side edges of the slit 24 and the protruding portion hanging down below the slit 24. Subsequently, the upright article M1 is pushed towards the outer guide 28A by air from the outer-feeding air nozzle 38 in section S5, resulting in the state shown in Figure 9, and is transported to the discharge chute 30 via the space between the outer guide 28A and the inner guide 28B. Articles M1 that were not upright in section S4 are blown down onto the inner rotating body 12 inside the annular portion 14A by the sorting air nozzle 36 provided in section S5.

[0038] As described above, the same effects as those of the first embodiment can be obtained in the article orientation alignment device of the second embodiment. [Explanation of Symbols]
