Problems to be Solved by the Invention

[0004] However, since the pharmaceutical product conveying device described in Patent Document 1 includes suction means for sucking the pharmaceutical products and changing their posture during the rotation of the direction regulating drum, the structure becomes complicated and the equipment cost increases.

[0005] Therefore, an object of the present invention is to provide an article conveying device that can smoothly convey articles in a stable posture while suppressing costs by simplifying the structure, and an article inspection device including the article conveying device.

Means for Solving the Problems

This first end face is inclined radially outward from the conveying drum and forward in the direction of rotation of the conveying drum. Therefore, when transferring the article placed on the first end face to the guide wall by gravity, the change in the orientation of the article is minimized as it is transferred to the guide wall and sent out in a prone position. As a result, articles can be smoothly sent out in a stable position without the need for complex structures such as suction means, and equipment costs can also be reduced. Furthermore, the items placed in the receiving recess and positioned on the first end face can be moved towards the second side and transported in a stable position.

[0018] According to the present invention, it is possible to provide an article conveying device that can smoothly convey articles in a stable position while reducing costs by simplifying the structure, and an article inspection device including the article conveying device.

[0019] The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by referring to the attached drawings and reading through the embodiments for carrying out the invention described below (hereinafter referred to as "embodiments"). [Brief explanation of the drawing]

[Figure 2] Figure 2 is a perspective view of the conveying drum and guide block that constitute the article conveying device according to this embodiment.

[Figure 6] Figure 6 is an enlarged perspective view of the accommodating recess in the transport drum shown in Figure 3. [Modes for carrying out the invention]

[0021] Embodiments of the present invention will be described in detail below with reference to the drawings. Figure 1 is a schematic diagram of the equipment equipped with the article conveying device 100 according to this embodiment. Figure 2 is a perspective view of the conveying drum 11 and guide block 27 that constitute the article conveying device 100 according to this embodiment. Figure 3 is an upper perspective view of the conveying drum 11 during the conveying operation of the article W. Figure 4 is a lower perspective view of the conveying drum 11 during the conveying operation of the article W.

[0022] As shown in Figures 1 to 4, the article conveying device 100 according to this embodiment has a conveying drum 11 and a guide wall 12. The conveying drum 11 rotates around a horizontal axis 13.

[0023] The article conveying device 100 is positioned below the supply device 14, which serves as a supply means for supplying articles W. Below the article conveying device 100, the inspection device 15 is positioned.

[0024] The article conveying device 100 receives articles W from the supply device 14 and sends them to the inspection device 15, which inspects the mass of the articles W. A sorting unit 16 is provided next to the inspection device 15, which sorts the articles W based on the inspection results of the inspection device 15. In this way, the article conveying device 100, together with the inspection device 15, constitutes an article inspection device that inspects articles W.

[0025] In this embodiment, the supply device 14 is described using a drum type as an example, but the supply device 14 is not limited to this. The supply device 14 may be, for example, a magazine type, a linear feeder type, etc. In this embodiment, the supply device 14 has a supply drum 22 that rotates around a horizontal axis 21, and the articles W are attracted by negative pressure on its outer surface and transported at predetermined intervals. The supply device 14 releases the attraction directly above the transport drum 11 and puts the articles W into a receiving recess 30 formed in the transport drum 11 of the article transport device 100. The supply drum 22 rotates in the opposite direction to the transport drum 11 so that the drop position of the articles W coincides with the receiving recess 30 of the transport drum 11. When the transport operation starts, the transport drum 11 and the supply drum 22 rotate intermittently or at a constant speed. The speed and type of rotation are determined, for example, based on the properties of the articles W and the processing performance of the next stage process.

[0026] Furthermore, in this embodiment, the destination of the article W delivered by the article conveying device 100 is described using the inspection device 15 as an example, but is not limited to the inspection device 15. The inspection device 15 has an inspection table 25, to which the article W delivered from the article conveying device 100 is transferred. The inspection table 25 becomes a weighing table when the inspection device 15 is a mass inspection scale. Note that the inspection device 15 is, for example, a mass inspection scale that inspects the mass of the article W, but it may also perform other inspections, such as external shape inspection using a camera.

[0027] The articles W to be transported by the article transport device 100 are relatively small in diameter, including articles with an outer diameter of several millimeters to several tens of millimeters that can be transported individually without packaging, bite-sized articles, and articles or molded products of predetermined shapes or spherical shapes manufactured by existing manufacturing facilities or manufacturing facilities without inspection functions, especially articles whose shape does not change during the transport process. Examples of articles W include formulations such as tablets, capsules, lozenges, and drops, as well as candy and chocolate. The shapes of articles W can be circular in plan view, star-shaped in plan view, or ellipsoidal in plan view. In the following explanation, we will use as an example a tablet called an R-tablet or round tablet, which is circular in plan view, has a small, flattened shape with a height (thickness) relative to its diameter, and has bulging spherical surfaces on both sides and a cylindrical circumferential surface, as an example of an article W to be transported.

[0028] In this embodiment, the conveying drum 11 rotates clockwise in a rotational direction RA about the horizontal axis 13. The conveying drum 11 rotates with the articles W supplied from the supply device 14 being accommodated in the accommodating recess 30. The accommodating recess 30 is formed in a slit shape that allows the articles W to move in a direction along the rotational direction RA of the conveying drum 11.

[0029] The conveying drum 11 has a first circumferential wall portion 31 on one axial side and a second circumferential wall portion 32 on the other axial side. The first circumferential wall portion 31 and the second circumferential wall portion 32 are formed with a gap between them, and a plurality of partition wall portions 33 are formed between the first circumferential wall portion 31 and the second circumferential wall portion 32 at intervals in the circumferential direction. A plurality of receiving recesses 30 are formed by the first circumferential wall portion 31, the second circumferential wall portion 32 and the partition wall portions 33. The outer edges of the partition wall portions 33 gradually protrude radially outward toward the first circumferential wall portion 31.

[0030] Figure 5 is an enlarged perspective view of the accommodating recess 30 in the transport drum 11 shown in Figure 2. Figure 6 is an enlarged perspective view of the accommodating recess 30 in the transport drum 11 shown in Figure 3.

[0031] As shown in Figures 5 and 6, the receiving recess 30 has a bottom surface 40, a first side surface 41, a second side surface 42, a first end surface 43, and a second end surface 44. The first side surface 41 is the inner surface of the first circumferential wall portion 31, and the second side surface 42 is the inner surface of the second circumferential wall portion 32. The first end surface 43 is the rear side surface of the partition wall portion 33 in the rotational direction RA, and the second end surface 44 is the front side surface of the partition wall portion 33 in the rotational direction.

[0032] The first side surface 41 constitutes one axial side surface of the transport drum 11 in the housing recess 30, and the second side surface 42 constitutes the other axial side surface of the transport drum 11 in the housing recess 30. The first end surface 43 constitutes the front end surface of the transport drum 11 in the rotational direction RA in the housing recess 30, and the second end surface 44 constitutes the rear end surface of the transport drum 11 in the rotational direction RA in the housing recess 30.

[0033] The first end face 43 is inclined radially outward of the conveying drum 11 and forward in the rotational direction RA of the conveying drum 11. Furthermore, the first end face 43 is inclined forward in the rotational direction RA of the conveying drum 11 towards the second side surface 42.

[0034] The first side surface 41 is inclined radially outward from the conveying drum 11, away from the second side surface 42. A guide surface 45, consisting of a flat surface connecting the first side surface 41 and the first end surface 43, is provided between the first side surface 41 and the first end surface 43. The guide surface 45 may also be a curved surface connecting the first side surface 41 and the first end surface 43.

[0035] As shown in Figures 1 and 2, the guide wall 12 is formed on a guide block 27 that is positioned adjacent to one side of the conveyor drum 11. The guide block 27 has a concave shape on the side facing the conveyor drum 11, and the guide wall 12 is formed in this concave portion. This guide wall 12 is an inclined surface that slopes radially inward of the conveyor drum 11 from the first side surface 41 side that constitutes the accommodating recess 30 of the conveyor drum 11 toward the second side surface 42 side.

[0036] The guide wall 12 is formed in an arc shape along the outer circumference of the conveying drum 11 and is positioned opposite to it along the outer circumference of the conveying drum 11. Because the guide wall 12 is positioned along the outer circumference of the conveying drum 11, it forms a conveying chamber 50 together with the receiving recess 30. In other words, the receiving recess 30 of the conveying drum 11 is closed by the guide wall 12 as it rotates, thus becoming a closed space, the conveying chamber 50.

[0037] The guide wall 12 of the guide block 27 faces the transport drum 11, which rotates in a clockwise direction RA, in the range of approximately 1 o'clock to approximately 6 o'clock. In this specification, the rotational position of the transport drum 11 may be described using the position of the numerals on the dial of a clock with hour and minute hands as an example for ease of understanding.

[0038] In the article conveying device 100, the starting position of the guide wall 12 becomes the supply position PA for the article W, and the ending position of the guide wall 12 becomes the discharge position PB for the article W. In other words, the article conveying device 100 conveys the article W, which is fed into the receiving recess 30 from the supply device 14 at the supply position PA, which is the starting position of the guide wall 12, in the rotational direction RA of the conveying drum 11 while receiving it in the conveying chamber 50 formed by the receiving recess 30 and the guide wall 12, and sends it to the inspection device 15 from the discharge position PB, which is the ending position of the guide wall 12.

[0039] Next, the operation of the goods transport device 100 will be explained. As shown in Figures 1 and 3, when the transport of goods W begins, the transport drum 11 of the goods transport device 100 rotates clockwise in the rotational direction RA. Goods W are dropped into the storage recess 30 at the supply position PA from the supply drum 22 of the supply device 14, which rotates synchronously in the opposite direction RB. This operation is performed continuously as the transport drum 11 rotates in relation to the storage recesses 30 which are provided at equal intervals in the circumferential direction of the transport drum 11. Therefore, goods W are stored in the storage recesses 30 in the range from the supply position PA at approximately 12 o'clock to the discharge position PB at approximately 6 o'clock (the range in the right half of Figure 1).

[0040] The supply device 14 transports the article W by holding its circumferential surface with its axis horizontal, so that both the front and back surfaces of the article W are visible from the front. Therefore, the article W that is placed into the receiving recess 30 at the supply position PA is placed into the receiving recess 30 in an almost upright position (see position PA in Figure 3).

[0041] As shown in Figure 3, the article W placed in the receiving recess 30 rolls downward in an upright position within the transport chamber 50 formed by the receiving recess 30 and the guide wall 12, due to gravity, within the upper rotational region of the transport drum 11 (for example, the range of positions P1 to P3 in Figure 3, from approximately 1 to approximately 3 o'clock), and reaches the first end face 43 (see position P2 in Figure 3). Then, the article W hits the first end face 43 and falls over, taking a prone position relative to the first end face 43 (see position P3 in Figure 3).

[0042] Furthermore, the article W, which is placed in the receiving recess 30 and leans against the first side surface 41, rolls downward in an oblique position within the transport chamber 50 due to gravity while in contact with the first side surface 41, and is guided to the first end surface 43 (see position P1 in Figure 3). When the article W reaches the first end surface 43, it assumes a prone position relative to the first end surface 43 (see position P3 in Figure 3). At this time, a guide surface 45 is provided between the first side surface 41 and the first end surface 43, so the article W rolling while in contact with the first side surface 41 has its position smoothly changed to a prone position by the guide surface 45 and is guided to the first end surface 43.

[0043] Furthermore, the article W that is placed into the receiving recess 30 at the supply position PA may fall over when placed in the recess. In this case, the article W slides down the bottom surface 40 of the receiving recess 30 in a prone position and reaches the first end surface 43, where it is positioned in a prone position relative to the first end surface 43.

[0044] Here, the first end face 43 on which the article W is placed in a prone position is inclined toward the second side face 42 in the forward direction of rotation RA of the conveying drum 11. Therefore, the article W placed on the first end face 43 is moved toward the second side face 42 due to the inclination of the first end face 43 (see position P3 in Figure 3). As a result, fluctuations of the article W placed on the first end face 43 are suppressed, and the article W is conveyed in a stable position.

[0045] As shown in Figure 4, the article W placed on the first end face 43 of the receiving recess 30 is gradually raised to an upright position as the conveying drum 11 rotates in the lower rotation region (the range of positions P4 to P6 from approximately 4 to 5 o'clock) (see position P4 in Figure 4). Then, as the conveying drum 11 rotates further, the raised article W is tilted by gravity towards the guide wall 12 of the guide block 27 that forms the conveying chamber 50 (see position P5 in Figure 4). As a result, the article W is transferred to the guide wall 12, and then the article W slides downward along the guide wall 12 by gravity, taking a prone position (see position P6 in Figure 4).

[0046] Here, the first end face 43 of the receiving recess 30 is inclined radially outward from the conveying drum 11 and forward in the rotational direction RA of the conveying drum 11. Therefore, when an article W placed on the first end face 43 is tilted by gravity and transferred to the guide wall 12, fluctuations in the orientation of the article W can be minimized. Thus, the collapse of the orientation of the article W when it is transferred to the guide wall 12 can be suppressed.

[0047] Furthermore, the guide wall 12, to which the article W is transferred from the first end face 43 of the receiving recess 30, is an inclined surface that slopes radially inward from the first side surface 41 to the second side surface 42 of the receiving recess 30, in the direction of the conveying drum 11. Therefore, when the article W, which was positioned towards the second side surface 42 on the first end face 43, is transferred to the guide wall 12 and conveyed, it is moved towards the first side surface 41 along the slope of the guide wall 12 (see position P6 in Figure 4). In this way, by constantly causing the article W, which has been transferred to the guide wall 12, to rotate slightly in a prone position without remaining stationary downwards or laterally on the guide wall 12, friction between the guide wall 12 and the article W can be suppressed. In other words, by making the frictional force of the article W against the guide wall 12 a kinetic friction force smaller than the static friction force, the article W can slide smoothly against the guide wall 12. This prevents the item W from rolling away due to friction with the guide wall 12 as it slides down the guide wall 12, and allows the item W to maintain a prone position.

[0048] Subsequently, the item W, positioned on the guide wall 12 in a prone position, is pushed out towards the discharge position PB from just before the discharge position PB (approximately at the 6 o'clock position P7) by the second end face 44 of the receiving recess 30, while still in a prone position, and sent to the inspection device 15.

[0049] As described above, according to the article conveying device 100 of this embodiment, an article W placed into the receiving recess 30 at the upper supply position PA is moved by gravity to the first end face 43 on the front side in the rotational direction RA as the conveying drum 11 rotates and is placed there. This first end face 43 is inclined radially outward from the conveying drum 11 and forward in the rotational direction RA of the conveying drum 11. Therefore, when the article W placed on the first end face 43 is transferred to the guide wall 12 by gravity, the change in the posture of the article W is minimized as much as possible, and the article can be transferred to the guide wall 12 and sent out in a prone position. As a result, articles can be smoothly sent out in a stable position without the need for complex structures such as suction means, and equipment costs can also be reduced.

[0050] Furthermore, with this article inspection apparatus comprising an article transport device 100 and an inspection device 15, the article transport device 100 can smoothly transport the article W to the inspection device 15 in a stable position, enabling stable inspection with high precision by the inspection device 15.

In addition, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited, as long as they can achieve the present invention.
