Description

[Technical Field]

[0001] The present invention relates to a medicine supply device capable of supplying medicines such as tablets and capsules of different shapes and sizes one by one. [Background technology]

[0002] Patent Document 1 describes a drug counting device for counting a large number of drugs. This drug counting device has a central disk member rotated by a first drive means and a circular member rotated by a second drive means. The disk member and the circular member are coaxially arranged so that their rotation axes are planar, and are rotated in opposite directions by the drive means. A drug guide portion is provided on the outer periphery of the circular member so as to extend outward.

[0003] However, in this medicine counting device, many medicines that are not supplied to the medicine guide are transferred in opposite directions between the disk member and the annular member, so that medicines moving from the disk member to the annular member collide with medicines already moving onto the annular member, and medicines moving from the annular member to the disk member collide with medicines on the disk member.

[0004] Meanwhile, Patent Document 2 describes a supply device that supplies small items in an aligned manner. This supply device has a disk-shaped first rotor rotated by a first driving means and an annular second rotor rotated by a second driving means. The first rotor's first rotation axis is tilted at a predetermined angle, and the second rotor's second rotation axis is vertically arranged. The first rotor is configured so that its uppermost portion is at the same height as the inner periphery of the second rotor. Furthermore, the inner periphery of the second rotor is integrally provided with a frame wall that surrounds the outer periphery of the first rotor.

[0005] In the supply device of Patent Document 2, the rotation of the first rotor causes the supply material to move from the upper end to the second rotor. Then, a regulating body provided on the second rotor allows only the supply material in a predetermined orientation to pass downstream, while the supply material in a different orientation falls from the inner periphery of the second rotor onto the first rotor. This prevents the supplied supplies from colliding with each other.

[0006] However, when this supply device is used to supply medicine, two or more supplies may pass through the restrictor at the same time and be supplied to the guide section to the discharge port in two radial rows. As a result, there is a problem of clogging at the entrance of the guide section. Furthermore, if the medicine is a tablet or a capsule containing a drug that is non-circular in plan view, even if it is supplied one by one, there is a problem of clogging at the entrance of the guide section or inside the guide section depending on the movement posture.

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0013] 1 shows a medicine counting device using a medicine supply device according to an embodiment of the present invention. This medicine counting device includes a medicine supply device, a switching valve unit 76, and a central control unit 83, which is a counting means, and automatically adjusts the mechanism of the medicine supply device to supply and count various types of medicines of different shapes and sizes one by one.

[0014] As shown in FIGS. 1 and 2, the exterior body 10 of the drug counting device includes an upper exterior body main body 11 and a lower stand 16. The exterior body main body 11 is a housing that is closed on all four sides and at the top and bottom, and its front cover 12 bulges forward from the stand 16. This front cover 12 is provided with a container mounting portion 13 on the left side in the figure for mounting a medicine container 1 to be handed to a patient and a collection container 2 for storing the medicine. In addition, a top cover 14 is rotatably attached to the rear side of the exterior body main body 11. This top cover 14 is provided with an insertion port 15 for exposing the inside of a frame 17, which will be described later. The stand 16 is a housing with an open top on which the exterior body main body 11 is placed. This stand 16 is used as needed to position the exterior body main body 11 at a predetermined height so that the containers 1 and 2 attached to the exterior body main body 11 do not abut on a table or other surface on which they are placed.

[0015] 3, the medicine supply device includes a substantially cylindrical frame 17, a disk-shaped first rotor 23, an annular second rotor 35, a height regulator 41 that regulates the height of the medicine to be supplied, a width regulator 52 that regulates the transport width of the second rotor 35, and a medicine guide unit 65 that includes an inner guide 66 and an outer guide 57. In this embodiment, the width regulator 52 and the outer guide 57 of the medicine guide unit 65 are formed from a single resin molded product.

[0016] As shown in FIGS. 3, 4, and 5, the frame 17 has a partition wall 18 that covers the outer periphery of the first rotor 23 and an outer wall 20 that covers the outer periphery of the second rotor 35. These are fixed to the top and bottom of the top panel of the exterior body main body 11. The partition wall 18 is generally cylindrical and extends from the inner periphery 36 of the second rotor 35 to the outer periphery of the first rotor 23, separating them. A notch 19 is provided in a portion of the lower periphery of the partition wall 18 to prevent interference with the rotating bracket 30 that secures the first drive motor 28 of the first rotor 23. The outer wall 20 is cylindrical and prevents the drug on the second rotor 35 from falling off. The outer wall 20 has a first notch 21 provided in a portion of the upper periphery and a second notch 22 provided in a portion of the lower periphery. The first cutout 21 exposes the second rotor 35 and is used to position the width restrictor 52 and the drug guide 65. The second cutout 22 exposes the gear member 38 of the second rotor 35 from the side. The frame 17 may have the partition wall 18 and the outer wall 20 integrally formed therewith.

[0017] The first rotor 23 is disk-shaped and disposed at an incline within the partition wall 18 so as to close the bottom of the partition wall 18. That is, as shown in FIGS. 6A and 6B, the first rotor shaft 24 of the first rotor 23 is disposed at an incline at a predetermined angle relative to the vertical direction. A plurality of ridges 25 are radially disposed on the upper surface of the first rotor 23 to provide resistance (rolling prevention) for moving the drug. The outer periphery of the first rotor 23 is provided with an inclined surface 26 that slopes downward toward the outside in the radial direction. The inclined surface 26 is disposed at a predetermined inclination angle so that the inner circumferential edge, which is the upper end, is located above the second rotor 35 and the outer circumferential edge, which is the lower end, is located below the inner circumferential edge.

[0018] A gear 27 is connected to the lower end of a first rotating shaft 24 of the first rotating body 23. This gear 27 is meshed with a gear 29 connected to the output shaft of a first drive motor 28, which serves as a first drive means, so that the first rotating shaft 24 can rotate around the center. The first rotating shaft 24 and the first drive motor 28 are attached to a rotating bracket 30. A guide bearing (not shown) is disposed on the side of the rotating bracket 30, and this bearing is engaged with a guide groove of a mounting bracket 31 fixed to the exterior body 11. As shown in FIGS. 4 and 5 , an arc-shaped gear piece 32 is fixed to the side of the rotating bracket 30. A gear 34 of an angle adjustment motor 33, which serves as an angle adjustment means, is meshed with this gear piece 32. The rotating bracket 30 can be rotated relative to the mounting bracket 31 by driving the angle adjustment motor 33. When the rotating bracket 30 is rotated, the first rotating body 23 is rotated together with the first drive motor 28, thereby adjusting the tilt angle of the first rotating body 23. The tilt angle is adjusted using the upper end of the first rotating body 23 as a fulcrum.

[0019] The second rotor 35 is annular and rotatably disposed on the upper end of the partition wall 18 so as to be located above the first rotor 23. As shown in FIGS. 6A and 6B, the second rotor 35 is disposed horizontally so that its second rotation axis (not shown) extends vertically. As a result, the second rotation axis of the second rotor 35 extends in a direction different from (not parallel to) and intersecting with the first rotation axis 24 of the first rotor 23. The angle between these rotation axes can be changed relatively by driving the angle adjustment motor 33, as described above. Furthermore, when viewed from the axial direction of the second rotation axis, the second rotor 35 is located outside the first rotor 23, and the first rotor 23 is located within the inner peripheral portion 36. Furthermore, due to the inclination of the first rotor 23, the outer periphery of the first rotor 23 is lower than the inner periphery 36 of the second rotor 35, forming a step of a predetermined height between them. This step is largest at the vertically lower end, which is the left side of the figure, and smallest at the vertically upper end, which is the right side of the figure, due to the inclination of the first rotor 23. The portion with the smallest step constitutes a transfer section 37 where, as the first rotor 23 rotates, the medicine supplied to the storage space partitioned by the first rotor 23 and the partition wall 18 transfers from the first rotor 23 to the second rotor 35. In the transfer section 37 of this embodiment, the inner periphery 36 of the second rotor 35 is configured to be positioned at approximately the same height as the outer periphery of the first rotor 23, with a gap sufficient to prevent the medicine from falling out. However, the height setting of the inner circumference 36 of the second rotor 35 and the outer circumference of the first rotor 23 in this moving section 37 may be such that the inner circumference 36 of the second rotor 35 is positioned above or below the outer circumference of the first rotor 23, as long as the drug can be transferred from the first rotor 23 to the second rotor 35.

[0020] 3 and 5, an annular gear member 38 is fixed to the underside of the second rotating body 35. A gear 40 of a second drive motor 39, which serves as a second driving means, is engaged with the gear member 38 through a second notch 22 in the outer wall 20. The outer periphery of the gear member 38 is supported by a support member (not shown). This allows the upper rotating member to rotate about the second rotation axis without moving along the second rotation axis.

[0021] The height restricting body 41 is disposed downstream of the moving portion 37 of the second rotor 35 in the rotation (drug transport) direction. The height restricting body 41 includes a height restricting member 42, a mounting member 44, and an actuation receiving member 45. As shown in FIGS. 7A and 7B, the height restricting member 42 is disposed above the second rotor 35. The height restricting member 42 extends from the outer periphery to the inner periphery 36 of the second rotor 35 and includes a guide surface 43 inclined at a predetermined angle along the drug transport direction. The mounting member 44 is connected to the height restricting member 42 and serves to mount the height restricting member 42 on the second rotor 35 across the width restricting body 52. ​​The actuation receiving member 45 is connected to the mounting member 44 and receives power for vertically moving the height restricting member 42 via the mounting member 44. A screw hole 46 for receiving power is provided vertically through the actuation receiving member 45.

[0022] A screw member 47 passes through the screw hole 46 of the height restrictor 41. The screw member 47 is supported by a bracket fixed to the top plate of the exterior body 11 so as to be rotatable but immovable in the axial direction. A gear 48 is connected to the lower end of the screw member 47. The gear 48 is engaged with a gear 50 of a height adjustment motor 49, which serves as a height adjustment means. The height adjustment motor 49 is driven to rotate the screw member 47, thereby adjusting the height so that the distance between the height restrictor 41 and the top surface of the second rotor 35 is approximately the same as the drug height. A drug detection sensor 51 is disposed downstream of the height restrictor 41 as a second drug detection means for detecting drugs that have passed below the height restrictor 41.

[0023] The width restricting body 52 is disposed on the second rotor 35 so as to be located further downstream in the drug transport direction than the height restricting body 41. The width restricting body 52 has a rectangular portion 53 extending tangentially relative to the outer periphery of the second rotor 35. The rectangular portion 53 is disposed so that the installation member 44 of the height restricting body 41 can bypass it, allowing it to move linearly without interfering with the installation member 44. Furthermore, the width restricting body 52 has a width restricting portion 54 continuous with the rectangular portion 53 downstream in the drug transport direction. The width restricting portion 54 has a first curved surface portion 55 having a diameter larger than the diameter of the inner periphery 36 of the second rotor 35. This configuration allows the distance between the inner periphery 36 of the second rotor 35 and the first curved surface portion 55 to be narrowest in only a portion of the circumferential direction. Here, the "transport width" refers to the width (area) through which the drug can pass from the inner periphery 36 of the second rotor 35 to the first curved surface portion 55. Furthermore, width restricting portion 54 includes second curved surface portion 56 that is connected to first curved surface portion 55 so that the transport width gradually widens downstream in the drug transport direction. Width restricting body 52 is connected to outer guide 57, which constitutes drug guiding portion 65, downstream in the drug transport direction of width restricting portion 54. Outer guide 57 is configured to extend tangentially to second curved surface portion 56 and perpendicularly to rectangular portion 53.

[0024] A connecting member 58 is connected to the width restricting portion 54 of the width restrictor 52 so as to extend parallel to the rectangular portion 53. An operation receiving member 59 is connected to the connecting member 58, similar to the height restrictor 41. A screw member 61 passes through a threaded hole 60 of the operation receiving member 59, and the screw member 61 is supported rotatably but axially immovably by a bracket fixed to the top plate of the exterior body main body 11. A gear 62 is connected to the outer end of the screw member 47, and a gear 64 of a width adjustment motor 63, which serves as width adjustment means for moving the width restrictor 52 in the horizontal direction, is engaged with the gear 62. When the width adjustment motor 63 moves the width restrictor 52 outward relative to the second rotor 35, the transfer width between the width restricting portion 54 and the inner periphery 36 of the second rotor 35 and the gap between the outer guide 57 and an inner guide 66, which will be described later, can be widened. Furthermore, when the second rotor 35 is moved inward, the transport width of the second rotor 35 and the gap between the guides 57, 66 can be narrowed. In this embodiment, the diameter (radius of curvature) of the first curved surface portion 55 of the width restricting portion 54 is set so that the width between the outer guide 57 and the inner guide 66 is approximately twice (2W) the transport width W between the inner circumferential portion 36 of the second rotor 35. In this embodiment, the transport width W is configured to be half the width of the drug to be transported. Note that for drugs that are elliptical or oblong in plan view, the drug width refers to the short side direction. Furthermore, the transport width W is not limited to half the drug width, and is preferably at least half the drug width and less than the drug width.

[0025] The drug guide portion 65 guides the drug that has passed through the width restriction portion 54 of the width restriction body 52 to a drug discharge member 73, which serves as a drug discharge port and will be described later. As shown in FIGS. 3 and 7A and 7B, the drug guide portion 65 is disposed on the second rotor 35 so as to be located downstream in the drug transport direction from the width restriction portion 54 of the width restriction body 52. ​​The inner guide 66 constituting the drug guide portion 65 is positioned parallel to the outer guide 57 on the radially inner side of the second rotor 35 and is disposed so as to extend tangentially to the inner periphery 36 of the second rotor 35. The inner guide 66 extends to the drug discharge member 73, and a bracket portion 67 is provided at its end for fixing to the upper plate portion of the exterior body main body 11. The spacing between the guides 57, 66 constituting the drug guide portion 65 is adjusted to approximately the same as the drug width by driving the width adjustment motor 63. The inner guide 66 is provided with an inclined edge 68 that slopes upward at a predetermined angle at its inner end located on the inner circumferential portion 36 of the second rotor 35, which is on the step between the first rotor 23 and the second rotor 35. The inner surface of this inclined edge 68 forms an inclined surface 69 that slopes downward.

[0026] 8, the medicine counting device includes a detection unit 70 that detects medicines, a shutter 74 that allows or disallows the discharge of medicines to the detection unit 70, and a switching valve unit 76 that distributes medicines that have passed through the detection unit 70, all of which are disposed below a medicine discharge member 73 disposed at the outlet of the medicine guide unit 65. The medicine discharge member 73 constitutes a medicine discharge port disposed radially outside the second rotor 35, and guides the medicines discharged from the medicine guide unit 65 to the detection unit 70.

[0027] As shown in FIGS. 9A and 9B, the detection unit 70, which is the first drug detection means, has a pair of housings 70A and 70B each having a square cylindrical shape. The upper housing 70A has a pair of light-emitting units 71A and 71B disposed on adjacent surfaces, and a pair of light-receiving units 72A and 72B disposed on the opposing surfaces. The lower housing 70B has a pair of light-emitting units 71C and 71D disposed on adjacent surfaces, and a pair of light-receiving units 72C and 72D disposed on the opposing surfaces. The pair of light-emitting unit 71A and light-receiving unit 72A, light-emitting unit 71B and light-receiving unit 72B, light-emitting unit 71C and light-receiving unit 72C, and light-emitting unit 71D and light-receiving unit 72D, which face each other, form a set of optical sensors (line sensors). The two sets of optical sensors (four sets in total) disposed in each of the two housings 70A and 70B are positioned at a predetermined interval in the axial direction. Furthermore, by arranging each housing 70A, 70B at a phase angle of 45 degrees from each other, it is possible to make the detection directions different. Furthermore, the detection unit 70 configured in this manner can be made smaller in plan view (occupied area) compared to when a regular octagonal housing is used that can accommodate all four optical sensors.

[0028] As shown in Figure 8, shutter 74 is disposed inside the outlet side of medicine discharge member 73. This shutter 74 can be rotated by drive motor 75, which is a discharge permission / prohibition means, from a discharge stop position extending horizontally to a discharge allowance position tilted downward. In the discharge stop position, the outlet of medicine discharge member 73 is closed to prevent the discharge of medicine into detection unit 70. In addition, in the discharge allowance position, the outlet of medicine discharge member 73 is opened to allow the discharge of medicine into detection unit 70.

[0029] The switching valve unit 76 is disposed below the detection unit 70 so as to be positioned at the container mounting portion 13 of the exterior body 11. The casing of this switching valve unit 76 has an inverted Y-shaped medicine passage 77 branching into a dispensing portion 78, which is a first passage portion, and a collecting portion 79, which is a second passage portion. The ends of the dispensing portion 78 and the collecting portion 79 are provided with stepped portions 78a, 79a for mounting the medicine container 1 and the collecting container 2. Of these, the dispensing portion 78, located on the left side in the figure, has three sets of stepped portions 78a that can mount three types of medicine containers 1 with different diameters (volumes). A switching valve is provided within the medicine passage 77 to switch the discharge destination to either the dispensing portion 78 or the collecting portion 79. The switching valve of this embodiment has a pair of oscillating members 80A, 80B disposed so as to extend from the inlet of the medicine passage 77 toward the dispensing portion 78 and the collecting portion 79. The first swinging member 80A on the left side of the figure opens and closes the dispensing unit 78, and the second swinging member 80B on the right side of the figure opens and closes the collecting unit 79. These swinging members 80A, 80B have elastically deformable elastic portions 81 disposed on their opposing surfaces. Each swinging member 80A, 80B is individually swung by a corresponding driving motor 82A, 82B, which serves as a driving means. In this embodiment, each swinging member 80A, 80B can be moved to three positions: a medicine dispensing position (first operating position) shown in FIG. 10A; a temporary stop position (second operating position) shown in FIG. 10B; and a medicine collecting position (third operating position) shown in FIG. 10C. At the temporary stop position, each swinging member 80A, 80B is rotated to an angle at which their elastic portions 81 come into contact with each other and are elastically deformed. The swinging members 80A, 80B may be made of an elastically deformable material.

[0030] As shown in FIG. 11, the medicine counting device including the medicine supply device operates in response to commands from the central control unit 83, and counts and supplies the required number of medicines according to prescription data. As shown in FIG. 18, the drug countermeasure device is provided with an inspection table. The inspection table is provided with a monitor 88, a first camera 89a that photographs the drug inside the drug container 1 from above the opening of the drug container 1 from which the drug has been dispensed, and a second camera 89b that photographs the label on the side of the drug container 1. The monitor 88 displays images captured by the first camera 89a, the second camera 89b, and a third camera 89c that is provided near the drug inlet of the drug countermeasure device and photographs the moving section 37 from the first rotator 23 to the second rotator 35 or the periphery of the height regulating body 41. The first camera 89a may be made movable so that it also functions as the third camera 89c, and the third camera may be eliminated.

[0031] Before dispensing the medicine, the operator reads the drug type ID (barcode) printed on the medicine bottle with the barcode reader 86, and only allows dispensing of the medicine if this drug type ID matches the correct drug indicated in the prescription data. This prevents the wrong medicine from being dispensed. Next, the operator reads the prescription ID (barcode) printed on the medicine container 1 that will receive the medicine, and only allows dispensing of the medicine if this prescription ID matches the prescription ID indicated in the prescription data. This prevents the wrong medicine container 1 from being taken.

[0032] Next, the operator operates the operation panel 84 to adjust the tilt angle of the first rotor 23, to feed the drugs into the drug feed space partitioned by the first rotor 23 and the partition wall 18, to input the number of drugs to be prescribed, and to start the counting process. In the counting process, the central control unit 83 performs an automatic adjustment (auto-calibration) process for each of the regulators 41, 52 according to the drugs, and then performs a counting process for actually counting the drugs. In this counting process, the central control unit 83 serves as a counting means for counting the drugs supplied based on detection by the detection unit 70.

[0033] The angle adjustment process of the first rotor 23 is performed according to the amount of medicine to be dispensed and the size and shape of the medicine. That is, when a large amount of medicine is to be dispensed, the inclination angle of the first rotor 23 is set to a steep gradient (close to vertical) so that the storage space formed between the partition wall 18, the first rotor 23, and the second rotor 35 is wide. Furthermore, in the case of spherical medicines that do not move to the second rotor 35 by rolling (rotating) on ​​the upper surface even when the first rotor 23 is rotated, the inclination angle of the first rotor 23 is set to a gentle gradient (close to horizontal). This allows a large number of medicines to be placed on the first rotor 23 and adjusted so that the medicines can move to the second rotor 35. This angle adjustment process may be configured to be automatically adjustable by disposing a medicine detection means on the moving section 37 of the second rotor 35, for example. In this case, this angle adjustment process is performed in the first stage of the automatic adjustment process.

[0034] In the automatic adjustment step of the counting process, height restrictor 41 is lowered and width restrictor 52 is moved inward. This prevents the medicine from being discharged even when rotating each of rotors 23, 35. In this state, as shown in FIG. 10A, oscillating members 80A, 80B of switching valve unit 76 are rotated toward dispensing section 78, opening dispensing section 78 and closing collection section 79, causing each of rotors 23, 35 to rotate. Thereafter, height restrictor 41 is gradually moved upward. When medicine detection sensor 51 detects that a medicine has passed through height restrictor 41, the movement of height restrictor 41 is stopped. Next, width restrictor 52 is moved outward so as to gradually widen. When detection unit 70 detects the discharge of the medicine, the movement of width restrictor 52 is stopped.

[0035] It is preferable that the positions of the height restricting member 41 and the width restricting member 52 are stored in advance for each drug. For this purpose, first, the barcode of the medicine bottle containing the medicine to be counted is read by a barcode reader 86 provided in the medicine counting device. Furthermore, when the medicine detection sensor 51 provided downstream of the height regulator 41 detects that the medicine has passed through the height regulator 41, the regulation height (or position) of the height regulator 41 at this time is stored in memory 87. At the same time, the third camera 89c photographs the medicine near the height regulator 41. Furthermore, when the sensor or detection unit 70 provided downstream of the width regulator 52 detects that the medicine has passed through the width regulator 52, the transfer width (or position) of the width regulator 52 at this time is stored in memory 87. In memory 87, the regulation height of the height regulator 41, the transfer width of the width regulator 52, and the medicine read by the barcode reader are stored in association with each other. The stored information on the restriction height and transport width may be displayed on the monitor 88 so that the operator can check it, and it may be possible to fine-tune it as necessary and overwrite the fine-tuned restriction height and transport width. This allows the barcode reader 88 to read the ID (barcode) of the drug type printed on the medicine bottle before the next supply of a drug to the first rotor 23. If the restriction height of the height regulator 41 and the transport width of the width regulator 52 associated with the drug corresponding to this ID are stored, they can be immediately adjusted to those values ​​and drug counting can begin. Furthermore, if the restriction height of the height regulator 41 and the transport width of the width regulator 52 associated with the drug are not stored, such as in the case of a new drug, the operation of acquiring these restriction heights and transport widths is performed as described above.

[0036] During the counting step of the counting process, the rotation speed of each rotor 23, 35 is increased compared to the automatic adjustment step, enabling high-speed counting. Then, once a number of drugs close to the set number of drugs have been dispensed, the rotation speed of the second rotor 35 is reduced, thereby slowing the discharge speed from the drug guide section 65. Once the set number of drugs has been dispensed, as shown in FIG. 10B, the oscillating member 80A located on the dispensing section 78 side is rotated toward the collecting section 79 side, blocking both the dispensing section 78 and the collecting section 79. At this temporary stop position, the elastic portions 81, 81 are elastically deformed by abutment and placed in a pressure-contact state. In this state, the dispensed drugs can be temporarily held on the upstream side of the pair of oscillating members 80A, 80B. Next, as shown in FIG. 10C, the oscillating member 80B located on the collecting section 79 side is rotated toward the oscillating member, opening the collecting section 79 side. As a result, the medicine temporarily accumulated on the upstream side of the pair of swinging members 80A, 80B is repelled towards the collection part 79 as the elastic part 81 on the side of the dispensing part 78 elastically restores its original shape. This reliably prevents excess medicine from being dispensed towards the side of the dispensing part 78. Finally, the rotation speed of the rotating bodies 23, 35 is increased to discharge all of the medicine in the frame 17 into the collection container 2.

[0037] The central control unit 83 counts based on input signals from four optical sensor groups (eight sensors per group) of the detection unit 70. In this embodiment, the detection unit 70 detects the medicine falling under its own weight (constant speed) as it is discharged, using the line sensors 71A, 72A-71D, and 72D from four different directions. As a result, the volume of the medicine passing through, including its shape, such as width and height, can be determined based on the input values ​​from the light-receiving units 72A-72D. Specifically, the width of the medicine from four different directions is determined based on inputs from the light-receiving elements of the light-receiving units 72A-72D. Furthermore, because the light-receiving units 72A and 72B of the upper housing 70A and the light-receiving units 72C and 72D of the lower housing 70B have different vertical heights, the horizontal cross-sectional shape of the falling medicine can be accurately determined based on the width determined by the light-receiving units 72A-72D, taking into account the difference in detection time due to the fall. Furthermore, by repeatedly performing this determination at predetermined intervals, the horizontal cross-sectional shape can be determined for each time period. Then, based on all horizontal cross-sectional shapes at each time, the volume (three-dimensional shape) including the shape of the falling medicine can be determined. Furthermore, the central control unit 83 stores all medicine information of various different shapes and sizes. Therefore, this medicine information is compared with the determined shape and volume to determine (confirm) the type of medicine being counted. Then, based on this determined medicine information, the number of dispensed medicines is counted. As a result, it is possible to detect when two medicines have passed together. Therefore, highly accurate counting can be achieved. When the dispensing of the medicine is completed, the opening of the medicine container 1 is directed toward the first camera 89a of the inspection table shown in Fig. 18 to photograph the medicine dispensed into the medicine container 1 as shown in Fig. 19(A), and then the label on the side of the medicine container 1 is directed toward the second camera 89b to photograph the prescription data as shown in Fig. 19(B). Next, the photographed image of Fig. 19(A), the photographed image of Fig. 19(B), and the photographed image of the medicine in the middle of being dispensed taken by the third camera as shown in Fig. 19(C) are simultaneously displayed on the monitor 88 to inspect whether the medicine has been dispensed according to the prescription data.

[0038] Next, a specific description will be given of the medicine feeding operation of the medicine supply device for feeding a disk-shaped tablet X, which is one type of medicine. Note that the feeding operation of this disk-shaped tablet X is similar to that for a spherical medicine.

[0039] 12(A) and 12(B), when the first rotor 23 is rotated, the tablet X is placed on its upper surface and rotates, and moves radially outward due to centrifugal force. Then, the tablet X on the first rotor 23 is transferred onto the second rotor 35 at the transfer section 37 located at approximately the same height as the second rotor 35.

[0040] The tablets X transferred to the second rotating body 35 are moved toward the medicine guide section 65, and their movement downstream is restricted by the height restricting body 41. For example, tablets X moving in a vertically stacked state may be dropped onto the second rotating body 35 or dropped from the inner peripheral section 36 onto the first rotating body 23 when the tablets X located on the upper side come into contact with the guide surface 43 of the height restricting body 41.

[0041] Tablets X that have passed through the height restrictor 41 come into contact with the first curved surface portion 55 of the width restrictor 52, which restricts the transport width, and are thereby moved toward the inner periphery 36 of the second rotor 35. The transport width of the second rotor 35 is set to half the drug width by the first curved surface portion 55 of the width restrictor 52, so only tablets X in contact with the width restrictor 52 can pass downstream of the width restrictor 52. That is, when tablets X are transported in two rows aligned radially, the inner tablets X are pressed by the outer tablets X in contact with the width restrictor 52 and fall from the inner periphery 36 of the second rotor 35 onto the first rotor 23. Even if tablets X are not aligned radially, tablets X whose center of gravity is located inside the inner periphery 36 of the second rotor 35 also fall from the inner periphery 36 onto the first rotor 23. Therefore, other tablets X that are not in contact with the width restrictor 52 are not transported downstream.

[0042] The tablets X that have passed through the first curved surface portion 55 of the width regulating body 52 are transported in a stable state through the region of the second curved surface portion 56 where the transport width is wider. Then, they are transported between the inner guide 66 and the outer guide 57 of the medicine guiding section 65, moved one by one in a line toward the outlet side, and discharged to the detection section 70. At this time, the tablets X1 that protrude inward from the inner periphery 36 of the second rotating body 35 come into contact with the end of the inner guide 66 and are guided between the inner guide 66 and the outer guide 57, or are dropped from the inner periphery 36 onto the first rotating body 23. Then, only the tablets X that have passed through this medicine guiding section 65 are supplied to the detection section 70 through the medicine discharge member 73, which is the medicine discharge port.

[0043] Next, a specific description will be given of the drug transport operation for capsules Y, which have a different shape and size from the disk-shaped tablets X. Note that the transport operation for capsules Y is similar to that for tablets with non-circular shapes such as oval shapes.

[0044] 13(A) and 13(B), when the first rotor 23 rotates, the capsules Y rotate on its upper surface and move radially outward due to centrifugal force. Then, the capsules Y on the first rotor 23 are transferred onto the second rotor 35 at a transfer section 37 located at the same height as the second rotor 35.

[0045] The capsules Y transferred to the second rotating body 35 are moved toward the drug guide section 65, and their movement downstream is restricted by the height restricting body 41, and the capsules Y moving in a stacked state are dropped onto the second rotating body 35 or dropped from the inner peripheral section 36 onto the first rotating body 23.

[0046] The capsules Y that have passed through the height restrictor 41 come into contact with the first curved surface 55 of the width restrictor 52, which restricts the transport width, and are thereby moved toward the inner periphery 36 of the second rotor 35, and their longitudinal orientation (posture) is corrected so that they extend along the drug transport direction. Only capsules Y that are in contact with the width restrictor 52 pass downstream of the width restrictor 52, and capsules Y that are not in contact with the width restrictor 52 fall from the inner periphery 36 of the second rotor 35 onto the first rotor 23. Furthermore, capsules Y1 whose posture cannot be corrected by coming into contact with the first curved surface 55 cannot maintain balance because their center of gravity is located inside the inner periphery 36 of the second rotor 35, as the transport width by the second rotor 35 is approximately half that of capsules Y1, and so they fall from the inner periphery 36 of the second rotor 35 onto the first rotor 23.

[0047] The capsules Y that have passed through the first curved surface portion 55 of the width restrictor 52 are transported in a stable state through the region of the second curved surface portion 56, where the transport width is wider. Then, they are transported between the inner guide 66 and the outer guide 57 of the medicine guide portion 65, moved one by one in a line toward the exit side, and discharged to the detection portion 70. At this time, capsules Y2 that have not been able to completely correct their position are corrected by abutting against the end of the inner guide 66, and are guided between the inner guide 66 and the outer guide 57, or dropped from the inner peripheral portion 36 onto the first rotor 23. Then, only the capsules Y that have passed through this medicine guide portion 65 are supplied to the detection portion 70 through the medicine discharge member 73, which is a medicine discharge port.

[0048] Because capsules Y are not flat like disc-shaped tablets X, they come into point or line contact with the second rotor 35 and tend to rotate as they move on the second rotor 35. Therefore, tablets that are not flat like capsules Y may change direction on the second rotor 35 after passing through the width restrictor 52 and before reaching the tablet guide section 65, and may be dropped onto the first rotor 23. Therefore, as shown in Figures 15(A) to (C), it is preferable to provide an annular rib 35a that protrudes upward on the inner peripheral edge of the second rotor 35. The rib 35a may have a triangular radial cross section with an inner circumferential surface flush with the inner circumferential surface of the second rotor 35, a pointed upper end, and a linearly inclined outer circumferential surface, as shown in Fig. 15(A), a concavely curved and inclined outer circumferential surface as shown in Fig. 15(B), or a rectangular radial cross section with an inner circumferential surface flush with the inner circumferential surface of the second rotor 35, a flat upper end, and a vertical outer circumferential surface, as shown in Fig. 15(C). By providing such rib 35a, tablets that are not flat come into contact with the upper surface of the second rotor 35 at two points, the rib 35a, as shown in Fig. 15(A), making it difficult for them to rotate on the second rotor 35 and preventing them from dropping onto the first rotor 23.

[0049] As described above, in the drug supply device of the present invention, the height restrictor 41 and width restrictor 52 allow drugs to be aligned one by one and supplied to the drug guide portion 65. This allows drugs to pass through the drug guide portion 65 one by one without causing problems such as clogging, and the drugs can be reliably supplied to the outside from the drug discharge member 73. Furthermore, since the multiple drugs being transported are not blocked by the restrictors 41 and 52 and the drug guide portion 65 but instead fall onto the first rotor 23, clogging at the restrictors 41 and 52 is reliably prevented, and multiple drugs are prevented from colliding with each other. This reliably prevents drugs from cracking or chipping. In particular, because the width restrictor 52 restricts the transport width of the second rotor 35 to half the drug width, drugs with non-circular shapes in plan view can only pass through if their longitudinal direction extends along the drug transport direction. This reliably prevents clogging at the entrance of the drug guide portion 65.

[0050] In addition, the height restriction by the height restriction body 41 and the transport width of the second rotator 35 by the width restriction body 52 are adjustable, which allows for the supply of a variety of medicines with different shapes and sizes. Furthermore, the width restriction body 52 and the outer guide 57 of the medicine guide section 65 are integrally provided and can be adjusted simultaneously, which improves the workability of adjustment and reduces the number of parts. Moreover, in this embodiment, the restriction bodies 41 and 52 are configured to be automatically adjustable, so the operator does not need to make any adjustments, greatly improving convenience in use.

[0051] Furthermore, the inner guide 66 of the medicine guiding section 65 is provided with an upwardly inclined inclined edge 68, which reliably prevents medicines transferred while protruding inward from the inner circumferential section 36 of the second rotor 35 from clogging the entrance of the medicine guiding section 65. This configuration is particularly effective when medicines that are non-circular in plan view are transferred at a slight angle, because it allows the posture to be corrected or the medicines to fall onto the first rotor 23. Furthermore, the inclination angle of the first rotation shaft 24 of the first rotor 23 is adjustable, so that the medicines can be reliably transferred to the transfer section 37 by rotation of the first rotor 23 and then moved onto the second rotor 35.

[0052] The medicine counting device using the medicine supply device reliably discharges medicines of different shapes and sizes one by one to the outside, detects the medicines with the detection unit 70, and reliably counts them with the central control unit 83. This allows the predetermined number of medicines to be reliably dispensed and prescribed to the patient. Furthermore, the switching valve unit 76 disposed on the container mounting unit 13 has a dispensing unit 78 for disposing the medicine container 1 to be delivered to the patient and a collecting unit 79 for disposing the collection container 2, thereby improving the operability of prescriptions. Furthermore, the oscillating members 80A and 80B, which function as switching valves, operate both the dispensing unit 78 and the collecting unit 79 to a pause position where they are closed after counting the number of medicines to be prescribed, thereby preventing more than the predetermined number of medicines from being dispensed into the medicine container 1. Furthermore, when the pair of oscillating members 80A and 80B is later positioned to collect the collection container 2, the elastic portion 81 elastically restores its original position, thereby ejecting the medicines held upstream of the pair of oscillating members 80A and 80B into the collecting unit 79, thereby reliably preventing excessive dispensing into the medicine container 1 through the dispensing unit 78.

[0053] Furthermore, if the third camera 89c is provided on the device body together with the height restricting body 41, movement of the height restricting body 41 will be hindered. For this reason, it is preferable to provide the third camera on the lid body, as shown in Fig. 18(a), rather than on the device body. Similarly, by providing the height restricting body 41 on the lid body, rather than on the device body, it is possible to prevent the height restricting body 41 and the width restricting body 52 from colliding and being damaged when the height restricting body 41 is moved radially outward from the second rotating body 35 to clean the first rotating body 23 and the second rotating body 35.

[0054] <Other embodiments> The medicine counting device of the present invention is not limited to the configuration of the above embodiment, and various modifications are possible, particularly with respect to the medicine supply device.

[0055] For example, in the embodiment, the height restricting member 41 is adjustable above the second rotor 35, and the width restricting member 52 is adjustable to adjust the transport width of the second rotor 35. However, these may be fixed and not adjustable. Even in this case, drugs of different shapes and sizes can be transported and supplied as long as they are at a height that allows them to pass between the second rotor 35 and the height restricting member 41 and have a width that allows them to pass through the transport width of the second rotor 35 restricted by the width restricting member 52. This increases the versatility of drug supply.

[0056] Furthermore, in the above embodiment, the width of the transport by the second rotor 35 can be changed by the width restrictor 52. However, the width restrictor 52 may be omitted. Even in this case, drugs of different shapes and sizes can be transported and supplied, as long as they are circular in plan view, spherical, or disk-shaped. In this case, drugs passing through the height restrictor 41 are supplied to the entrance of the drug guide 65 in two radial rows. However, since the drug guide 65 has a pair of guides 57, 66 spaced at approximately the same interval as the drug width, drugs located on the inner periphery 36 side of the second rotor 35 abut against the inner guide 66 and fall from the inner periphery 36 of the second rotor 35 onto the first rotor 23. This prevents drugs from clogging the entrance of the drug guide 65 and ensures that drugs are discharged one by one.

[0057] Furthermore, although height restrictor 41 is adjustable by linear movement in the vertical direction and width restrictor 52 is adjustable by linear movement in the horizontal direction, they may be adjustable by rotation as shown in Fig. 14A. Moreover, width restrictor 52 is integrally provided with outer guide 57 constituting drug guide section 65, but as shown in Fig. 14B, they may be provided separately and individually adjustable. In this case, width restrictor 52 excluding outer guide 57 may be made of an elastically deformable material and configured to be partially movable to adjust the transport width.

[0058] Furthermore, in the above embodiment, the first rotor 23 is arranged so as to be inclined at a predetermined angle, and the second rotor 35 is arranged horizontally, but the first rotor 23 may be arranged horizontally, and the second rotor 35 may be arranged so as to be inclined at a predetermined angle. Of course, both the first rotor 23 and the second rotor 35 may be arranged so as to be inclined at a predetermined angle. In other words, it is only necessary that the rotation axes of the first rotor 23 and the second rotor 35 intersect at an angle that allows the drug to move.

[0059] In addition, while the first rotor 23 and the second rotor 35 are configured to rotate in the same direction in the above embodiment, they may be configured to rotate in opposite directions. Furthermore, while the partition wall 18 is configured as a fixed, non-rotatable type in the above embodiment, it may be configured to be rotatable. In this case, the partition wall 18 may rotate integrally with the second rotor 35, or may rotate independently on the same axis. Furthermore, while the inner guide 66 of the medicine guide section 65 is disposed at the edge of the inner periphery 36 of the second rotor 35 in the above embodiment, it may be disposed at a position radially outward from the edge of the inner periphery 36, as long as the position allows medicines with misaligned centers of gravity to fall from the inner periphery 36 onto the first rotor 23.

[0060] In the above embodiment, the first rotor 23 and the second rotor 35 are fixed in the axial direction, and the first rotor 23 and the second rotor 35 are set to have approximately the same height at the transfer section 37 where the drug moves from the first rotor 23 to the second rotor 35. However, the first rotor 23 may be moved in the axial direction to adjust the amount of drug transferred. When there is a large amount of drug, the first rotor 23 is moved downward, and the drug forms a mass on the first rotor 23 and moves to the transfer section 37, and the drug at the top of the mass of drug is transferred to the second rotor 35. When the amount of drug decreases and there is no drug on the second rotor 35, the first rotor 23 is moved upward so as to approach the second rotor 35, making it easier for the drug to move from the first rotor 23 to the second rotor 35.

[0061] In the above embodiment, the distance between the moving section 37, through which the medicine moves from the first rotating body 23 to the second rotating body 35, and the height restrictor 41 is constant. However, this distance may be variable. This is possible by changing the tilt direction of the first rotating body 23. When there are many medicines, if the distance from the moving section 37 to the height restrictor 41 is short, many medicines will get stuck or fall off the height restrictor 41, and it will take a long time for them to be discharged. Therefore, the position of the moving section 37 is moved farther away from the height restrictor 41 so that the distance from the moving section 37 to the height restrictor 41 is longer. When there are few medicines, if the distance from the moving section 37 to the height restrictor 41 is long, it will take a long time for the medicines to reach the height restrictor 41. Therefore, the position of the moving section 37 is moved closer to the height restrictor 41 so that the distance from the moving section 37 to the height restrictor 41 is shorter.

[0062] 16(A), an openable lid 84 may be provided at the open end of collection section 79, which is the second passage section of medicine passage 77, and may be biased in the direction of closing the open end by spring 85. When lid 84 is pressed by the mouth of collection container 2, lid 84 opens and the mouth of collection container 2 can be positioned below the open end of collection section 79. This allows medicine to be stored in collection section 79 closed by lid 84, and the stored medicine can be collected all at once into collection container 2. Furthermore, by providing a holding mechanism for holding medicine container 1 in the medicine supply device and having the holding mechanism hold medicine container 1, medicine dispensed from dispensing section 78 can be dispensed into medicine container 1 without having to hold medicine container 1 by hand.

[0063] The operator visually checks whether all of the medicines supplied onto first rotator 23 have been dispensed. However, there is a risk that the operator may determine that all of the medicines have been dispensed even when some medicines remain undispensed. In this case, if a different medicine is supplied to first rotator 23 to count the next medicine, different types of medicines may become mixed, resulting in not only a counting error but also the supply of the wrong medicine to the patient, which could lead to a medical accident. Therefore, after counting the medicines, the second rotor 35 is rotated in reverse for a predetermined time before the next medicine is dispensed. As a result, even if any medicine remains on the second rotor 35, particularly between the inner guide 66 and the outer guide 57, the width restrictor 52 causes the medicine to fall onto the first rotor 23. After this, the outer guide 57 is moved inward as far as possible to close the tablet guide section 65, and the height restrictor 41 is raised as far as possible. The height restrictor 41 may be raised before the outer guide 57 is moved. Next, the first rotor 23 and the second rotor 35 are rotated forward. As a result, the medicine on the first rotor 23 moves onto the second rotor 35, passes through the height restrictor 41, and is then dropped onto the first rotor 23 by the width restrictor 52, and this process is repeated. When it is detected that a medicine has passed through the height restrictor 41 or the width restrictor 52, an alarm can be sounded to notify the user that there is any medicine remaining that has not been dispensed. The timing for reversing the rotation of the second rotor 35 is preferably after the lid 84 of the recovery section 79 of the second passage is changed from open to closed and the drug stored in the recovery section 79 is recovered, for example.

[0064] In the above embodiment, the first rotating body 23 is formed smaller than the second rotating body 35 and is arranged within the projected area of ​​the inner circumference of the second rotating body 35, but as shown in Figure 17, it is also possible to make the first rotating body 23 larger than the second rotating body 35 and configure it so that a portion of the outer circumference on the opposite side of the moving part 37 of the first rotating body 23 is positioned outside the outer circumference of the second rotating body 35.

[0065] In the above embodiment, an audit function is provided to check the drug type ID and prescription ID, but an inventory support function may also be provided to check only the drug type ID and record the drug ID and drug count. The inventory support function allows the pharmacy to periodically check the stock of medicines used at the pharmacy outside of business hours. Also, the device may have a counting function that simply counts the quantity of medicine without checking either the drug type ID or the prescription ID.

[0066] In the above-described embodiment, if the tip of the inner guide 66 (the tip on the upstream side in the direction of rotation of the second rotor) is positioned higher than the top surface of the second rotor 35, the drug transported on the second rotor 35 may collide with the tip of the inner guide 66 and be damaged. Therefore, as shown in FIG. 20, the tip of the inner guide 66 is preferably positioned inside the inner periphery of the second rotor 35 and lower than the top surface of the second rotor 35. Note that, unlike the above-described embodiment, the second rotor in FIG. 20 rotates clockwise. It is also preferable to provide a protruding portion 66a extending from the lower end of the inner guide 66 toward the inner periphery of the second rotor 35 to fill the gap between the lower end of the inner guide 66 and the inner periphery of the second rotor 35. This prevents the drug that strikes the inclined surface 69 and is returned to the second rotor 35 from falling through the gap between the lower end of the inner guide 66 and the inner periphery of the second rotor 35.

[0067] <First rotor lift mechanism> In the above embodiment, the first rotor 23 is fixed in position in the vertical direction relative to the second rotor 35. In this case, the capacity of the drug supply space above the first rotor 23 is limited. Therefore, the first rotor 23 may be provided so as to be movable up and down relative to the second rotor 35. The mechanism for moving the first rotor 23 up and down will be described below.

[0068] 21 and 22 show an embodiment in which the first rotor 23 is provided so as to be movable up and down relative to the second rotor 35 in a direction parallel to the second rotation axis (not shown) of the second rotor 35. The first rotor 23, together with the first drive motor 28, is supported by a bracket 91 at the upper end of a rectangular cylindrical movable frame 90. A pair of rollers 92 serving as cam followers are provided on the outer surfaces of both side walls at the lower end of the movable frame 90. A vertically extending protrusion 93 is formed on the outer surfaces of the other side walls of the movable frame 90 where the rollers 92 are not provided. The movable frame 90 is housed inside a rectangular cylindrical fixed frame 95 fixed to a base plate 94 of the device main body. A vertically extending guide protrusion 96 is formed on the inner surface of the fixed frame 95, with which the protrusion 93 of the movable frame 90 slidably engages. Notches 97 are formed downward from the upper ends of both sides of the fixed frame 95, and the shafts of the rollers 92 fit into these notches 97 so that the rollers 92 are positioned outside the notches 97.

[0069] A cam barrel 99 having a cam surface 98 formed on its upper end is rotatably mounted on a base plate 94 of the device body. A roller 92 of the movable frame 90 is rollably mounted on the cam surface 98. The cam surface 98 is made up of a first inclined surface 98a that rises at an inclination of approximately 20° from the lowest first point P1, a second inclined surface 98b that descends at an inclination of approximately 60° from the highest second point P2 of the first inclined surface 98a, a third inclined surface 98c that rises at an inclination of approximately 20° from a third point P3 of the second inclined surface 98b, and a fourth inclined surface 98d that descends at an inclination of approximately 60° from the highest fourth point P4 of the third inclined surface 98c to the first point P1. When the rollers 92 of the movable frame 90 are located at the first point P1 and the third point P3, which are the lowest positions, the first rotating body 23 supported by the movable frame 90 is located at the lowest position, and when the rollers 92 are located at the second point P2 and the fourth point P4, which are the highest positions, the first rotating body 23 is located at the highest position. The cam barrel 99 has a drive shaft 100 that protrudes downward from the base plate 94. A worm gear 101 is provided on the drive shaft 100, and the worm gear 101 is connected to an elevator motor 104 via a worm 102 and a drive gear 103. When the cam cylinder 99 is rotated by driving the lifting motor 104, the rollers 92 of the movable frame 90 roll along the cam surfaces 98 of the cam cylinder 99, causing the movable frame 90 to slowly rise from the lowest first point P1 and third point P3 to the highest second point P2 and fourth point P4, and then to rapidly fall from the highest second point P2 and fourth point P4. Note that a rack and pinion mechanism may also be used instead of such a cam mechanism.

[0070] The lower end of a cylindrical partition wall 18 is attached to the upper end of the fixed frame 95. The partition wall 18 consists of an elliptical lower portion 18a and a generally conical upper portion 18b. The lower portion 18a of the partition wall 18 is an elliptical cylinder that accommodates the tilted first rotor 23 with minimal clearance. The upper end of the lower portion 18a is elliptical and connects to the lower end of the upper portion 18b, tilted along the outer periphery of the first rotor 23 at its highest position. The lower portion of the upper portion 18b facing the highest position of the tilted first rotor 23 coincides with the upper end of the lower portion 18a, while the portion facing the lowest position of the tilted first rotor 23 extends diagonally upward and away from the upper end of the lower portion 18a. The upper end of the upper portion 18b is circular and fits along the inner periphery of the second rotor 35.

[0071] As shown in Figure 23(A), on the inner surface of the portion of the upper part 18b of the partition wall 18 facing the lowest position of the inclined first rotor 23, there are formed a tablet rise suppression surface 105 that slopes upward from the lower end to approach the first rotor 23, and a tablet drop guide surface 106 that slopes downward from the upper end to approach the first rotor 23. The tablet rise suppression surface 105 moves tablets that have accumulated on the outer periphery as the first rotor 23 rotates toward the center of the first rotor 23, thereby preventing these tablets from climbing onto the second rotor 35 above, joining with tablets being transported on the second rotor 35, and blocking the space between the inner guide 66 and the outer guide 57. Downstream of the inner guide 66 of the second rotating body 35, there is no longer any need to suppress the rise of the tablet; rather, the tablet must be allowed to rise toward the tablet transfer section 37 from the first rotating body 23 to the second rotating body 35, so the inclination of the tablet rise suppression surface 105 is gentle, as shown in Figure 23(B).

[0072] The operation of the lifting mechanism for the first rotor 23 will be described. When operating the lifting mechanism for the first rotor 23, a drug detection sensor 51 is used to detect drugs being transported on the second rotor 35. The drug detection sensor 51 is provided on the outer wall 20 around the second rotor 35. A recess 107 of a size that prevents a tablet from entering is provided on the inner surface of the outer wall 20, and a hole 108 is provided at the bottom of the recess 107. A lens 109 that transmits light from the drug detection sensor 51 is embedded in the hole 108. This prevents the tablet from coming into contact with the lens 109, preventing it from coming into contact with and damaging the lens 109 while being transported on the second rotor 35.

[0073] When the medicine is supplied to the first rotor 23, the first rotor 23 is at the lowest position. When the first rotor 23 and the second rotor 35 rotate, the tablets on the first rotor 23 accumulate on the outer periphery and rise up, then move from the first rotor 23 to the second rotor 35 via the moving part 37, and are transported on the second rotor 35 and discharged as described above. As the medicine is sequentially discharged, the rise of the medicine on the first rotor 23 decreases, and it is no longer possible for the medicine to move from the first rotor 23 to the moving section 37 onto the second rotor 35, and no more medicine is transported on the second rotor 35. Then, the medicine detection sensor 51 no longer detects the medicine being transported on the second rotor 35, and the first rotor 23 is moved upward to approach the second rotor 35. As a result, the medicine on the first rotor 23 moves from the first rotor 23 to the moving section 37 onto the second rotor 35, and the medicine detection sensor 51 detects the medicine being transported on the second rotor 35, so the upward movement of the first rotor 23 is stopped. This allows the medicine to continue being discharged. By repeating this process, all of the medicine on the first rotor 23 can be discharged. When a drug is to be supplied onto the first rotor 23, the first rotor 23 is moved downward so as to be separated from the second rotor 35 in order to secure a storage space for the drug.

[0074] The mechanism for moving the second rotor 35 up and down is not limited to the above embodiment, and the first rotor 23 may be moved up and down parallel to its first rotation axis 24 as shown in FIG. 27, the first rotor 23 may be moved up and down along an arc S centered on point O, which is located within a plane formed by the first rotation axis 24 of the first rotor 23 and the second rotation axis (not shown) of the second rotor 35. In this case, point O, which is the center of the arc, is arbitrary, but it is preferable to configure the first rotor 23 so that its highest position is located toward the center of the arc. As a result, when the first rotor 23 is moved downward along the arc, the inclination of the first rotor 23 increases. Generally, the more medicines loaded on the first rotor 23, the more likely the top surface of the medicine group is to be horizontal. If the top surface of the medicine group is horizontal, the top surface of the medicine group located above the lowest position of the first rotor 23 will reach the inner guide 66 of the second rotor 35 and mix with the medicines being transported in a single file by the inner guide, resulting in a problem of medicine clogging. However, as shown in Figure 27, if the inclination of the first rotor 23 that has moved downward is large, it is difficult for the upper surface of the group of tablets to become horizontal even if a large amount of medicine is poured onto the first rotor 23. As a result, the upper surface of the group of tablets on the first rotor 23 near the inner guide 66 becomes lower than the second rotor 35, and the above-mentioned problem of mixing with the medicine being transported on the second rotor 35 and causing clogging can be avoided.

[0075] <Medicine delivery system> A drug supply system in which the counting operation of the drug counting device of the present invention (hereinafter simply referred to as counter 110) is processed in conjunction with prescription data will be described with reference to the block diagram of Figure 28, the flowcharts of Figures 29-36, and the screen diagrams of Figures 37-43. Multiple counters 110 are installed in large pharmacies and are connected to the pharmacy's host system 111111 along with other drug supply devices and drug packaging devices. A pharmacist who performs audits and the like is stationed on the host system 111111 side, and an operator (drug technician) who operates the counter 110 is stationed on the counter 110 side.

[0076] Host system 111 is a system that dispenses necessary medicines based on the patient's prescription data and supplies them to the patient. As shown in Figure 28, host system 111 includes a control unit 112 that exchanges data with counter 110, other medicine supply devices, and medicine packaging devices, an audit unit 113 that collates the medicines to be supplied to the patient with the prescription data, a prescription printer 114 that prints prescriptions according to the prescription data, a label printer 115 that prints labels to be affixed to vials according to the prescription data, and a prescription master 116 that stores the prescription data.

[0077] The counter 110 is equipped with a control unit 117 that controls the operation of the counter 110 and exchanges data with a control unit 112 of the host system 111, a barcode reader 118 that reads barcodes on prescriptions, original drug bottles, and vials, a tray photography camera 119 (similar to the third camera 89c in the above embodiment) that photographs a drug on the tray of the counter 110 (this refers mainly to the drug storage area composed of the first rotor 23, second rotor 35, and partition wall 18 in the above embodiment), and a vial / prescription photography camera 120 that photographs the vial and prescription supplied by the patient. The counter 110 also includes a drug master 121 that stores the names, shapes, sizes, etc. of various drugs, a vial master 122 that stores the vial sizes and the number of drugs contained therein, an image data master 123 that saves images taken by the tray photographing camera 119 and the vial / prescription photographing camera 120, a communication data master 124 that stores communication data such as transmitted data and received data with the control unit 112 of the host system 111, and a touch panel type operation display panel 125.

[0078] Power-on and login actions As shown in FIG. 29, when an operator on the counter 110 side turns on the power of the counter 110 (S101), the control unit 117 starts an application, waits for login from the host system 111 side, starts a web service host (S102), and initializes the counter 110 (S103). Meanwhile, on the host system 11 side, when the pharmacist logs in to the host system 111 upon powering on the counter 110 (S201), the control unit 112 on the host system 111 side performs user authentication (S202) and transmits a login request to the counter 110 side (S203). As a result, when the counter 110 side receives the login request from the host system 111 side (S104), it transmits a login response to the host system 111 side (S105). When the host system 111 side receives the login response from the counter 110 side, it recognizes the login (S204). In this way, the counter 110 side cannot perform counting processing linked to the prescription unless it receives a login request from the host system 111 side.

[0079] After logging in, the menu screen shown in Fig. 37 is displayed on the operation display screen of the counter 110. The menu screen is configured with a touch panel, and is provided with a counting for Rx button for performing counting processing linked to a prescription (Rx), a counting for manual button for performing counting processing of the required amount of medicine without linking with a prescription, a master maintenance button for adding or modifying medicines in the medicine master 121, and an advanced setting button for performing environment settings, etc.

[0080] Counter-based medication prescription processing When the operator at the counter 110 touches the prescription counting process button, a prescription scan standby screen shown in FIG. 38 is displayed (S106). Furthermore, when the operator issues a prescription issuing instruction to the host system 111, the control unit 112 of the host system 111 receives the prescription issuing instruction (S206), performs a prescription issuing process, and performs a printing process with the prescription printer 114 (S207). The prescription scan standby screen of the counter 110 instructs the operator to scan the prescription as shown in Fig. 38, so the operator receives the issued prescription and scans it with the barcode reader 118 of the counter 110. Once the scan is performed (S107), the control unit 117 of the counter 110 performs a prescription reading process (S108) and displays the count screen shown in Fig. 39 (S109). Next, the control unit transmits an Rx data request to the host system 111 to receive detailed prescription information from the host system 111 (S110). When the host system 111 receives the Rx data request from the counter 110 (S208), it transmits an Rx data response together with the prescription data (S209). When the counter 110 receives the Rx data response (S111), it saves the received data in the communication data master 124 (S112), and displays the prescription data (prescription number (Rx), patient name (Patient), drug code and name, and requested amount (Request)) on the count screen as shown in the figure (S113), and searches the drug master 121 for an image of the drug corresponding to the prescription data and displays it on the count screen (S114).

[0081] Next, the control unit 117 of the counter 110 searches the medicine master 121 for the size of the medicine corresponding to the prescription, and adjusts the tray size of the counter 110 based on this medicine size (S115). The tray size is the height restricted by the height restrictor 41 and the transport width of the second rotator 35 restricted by the width restrictor 52, as already described. The count screen instructs the operator to scan a stock bottle, as shown in FIG. 39, so the operator picks up a stock bottle corresponding to the medicine name in the prescription data and scans it with the barcode reader 118 of the counter 110. After scanning (S116), the control unit 117 of the counter 110 performs a stock bottle barcode reading process (S117) and checks whether the medicine in the stock bottle is a medicine to be counted (S118). If the result is correct, "OK" is displayed in the stock bottle check (Check a Stock Bottle) item in the check column of the count screen of FIG. 39, and a message is displayed requesting the operator to insert the medicine (S119). When the message "OK" is displayed and an instruction to add medicine is displayed, the operator adds the medicine from the original bottle to the tray of the counter 110.

[0082] Next, the control unit 117 of the counter 110 instructs the host system 111 to issue a label (S120). When the control unit 112 of the host system 111 receives the label issuance instruction from the counter 110 (S210), the control unit 112 uses the label printer 115 to issue a blank label with prescription data printed on it (S211). The operator at the counter receives the issued label and attaches it to a vial. The control unit 117 of the counter 110 instructs the count screen to scan the label (S121). This causes the operator to scan the label attached to the vial with the barcode reader 118 of the counter 110. When the scan is performed (S122), the control unit 117 of the counter 110 performs a label barcode reading process (S123), checks whether the prescription displayed on the label is a prescription to be counted (S124), and if it is correct, displays "OK" in the label check (Check a Vial Label) item in the check column of the count screen in Figure 39.

[0083] When the label check is "OK," the operator instructs the counter 110 to start capturing tray images on the count screen. Upon receiving the instruction to start capturing tray images (S125), the control unit 117 of the counter 110 operates the counter 110 (S126), captures a tray image (S127), and displays the captured tray image on the left side (Live) of the camera image capture screen in FIG. 40 (S128). The counter 110 continues to operate until the drug sensor 51 detects that the drug on the first rotor 23 has moved to the second rotor 35, been transported along the second rotor 35, and reached the height restrictor 41. The tray image is captured in real time as an image of the drug stopped at the height restrictor 41. The operator confirms that the drug in the tray image displayed on the camera image capture screen is the same as the prescribed drug image (S129). If the operator cannot confirm the drug markings, etc., the counter 110 retries the operation until confirmation is confirmed. At this time, the confirmation of the medicine and instructions to retry are given by a pharmacist in the inspection department 113 of the host system 111. Once the image has been confirmed (S129), "OK" is displayed in the Capture Tray item in the Check column of the count screen in Fig. 39, and the tray image as shown on the right side of Fig. 40 (Still picture) is saved in the image data master 123 (S130).

[0084] When the tray image becomes "OK," the operator sets the vial in the dispensing unit 78 of the counter 110. When the control unit 117 of the counter 110 detects the setting of the vial (S131), it performs a counting process (S132). When the counting is completed, the control unit 117 of the counter 110 displays the counted value in the center of the count screen and displays "OK" in the count item of the check column. When the count becomes "OK," the count screen instructs the operator to scan the stock bottle from which the medicine remaining on the tray will be collected. The barcode reader 118 of the counter 110 scans the stock bottle into which the medicine has been placed. When the scan is performed (S133), the control unit 117 of the counter 110 performs a stock bottle barcode reading process (S134), checks whether the stock bottle is correct (S135), and if correct, performs a medicine collection process (S136).

[0085] For safety reasons, it is optional to recount the medications counted by the counter 110 and contained in the vials. However, when the operator instructs recounting (S137) and detects the setting of the vial (S138), the control unit 117 of the counter 110 performs a recounting process (S139). After completing the recounting, the operator attaches a cap to the vial and places the vial and prescription under the vial / prescription photographing camera 120, with the vial placed on the prescription. The operator then instructs the counter 110 to photograph the vial / prescription on the counting screen. When an instruction to photograph the vial / prescription is received (S140), the control unit 117 of the counter 110 performs a vial / prescription photographing process (S141) and displays the photographed image of the vial / prescription in the second row of the photo column on the counting screen (S142). Note that if the vial label or the contents of the prescription cannot be confirmed from the photographed image, the vial / prescription photographing process can be retried. When the pharmacist at the host system 111 confirms that the series of operations has been completed (S143), the control unit 117 of the counter 110 creates prescription completion data (S144) and transmits the prescription completion data to the host system 111 (S145). The control unit 112 of the host system 111 receives the prescription completion data (S212) and stops the series of operations.

[0086] Vial division The control unit 117 of the counter 110 selects the size of the vial based on the prescription data, but if the prescribed amount cannot be accommodated in one vial, multiple vials (in the example of Figure 41, three 40DRs) are displayed in the Split Vial column, as shown on the screen of Figure 41, and it is displayed that 40 drugs will be accommodated in two vials and 20 drugs will be accommodated in the remaining vial, so the specified amount will be counted and accommodated in each vial accordingly.

[0087] Processing when stockouts occur During the counting process, if the tray runs out of medicines before the specified amount of medicines is counted up, i.e., if the tablet detection sensor no longer detects the medicines, a stockout state occurs. In this case, medicines must be added to the tray. As shown in Figure 34, when it is determined that a stockout has occurred (S151), the control unit 117 of the counter 110 temporarily stops dispensing and counting medicines (S152) and issues an instruction to scan a new original bottle. The operator takes out a new original bottle corresponding to the medicine name in the prescription data and scans it with the barcode reader 118 of the counter 110. After scanning (S153), the control unit 117 of the counter 110 performs a new original bottle barcode reading process (S154) and checks whether the medicine in the new original bottle is a medicine to be counted (S118). Thereafter, the counting process continues (S132).

[0088] Prescription processing of liquid medicines and boxed medicines other than tablets Liquid medicine bottles and boxed medicines supplied in boxes cannot be counted by the counter 110. However, the counter 110 allows auditing in conjunction with prescriptions. When a liquid medication or box is prescribed, the operator places the liquid medication bottle or box below vial / prescription photographing camera 120. The operator then issues an instruction to photograph the liquid medication bottle / box on the count screen. As shown in FIG. 35, when an instruction to photograph the liquid medication bottle / box is received (S161), control unit 117 of counter 110 performs a liquid medication bottle / box photographing process (S162) and displays the photographed image of the liquid medication bottle / box in the second row of the photo column on the count screen (S163). Note that if the contents of the liquid medication bottle or box label cannot be confirmed from the photographed image, the liquid medication bottle / box photographing process can be attempted again (S164). Next, the operator places the prescription for the liquid or boxed medication below the vial / prescription photography camera 120. Then, the operator issues an instruction to photograph the prescription on the count screen. When the instruction to photograph the prescription is issued (S165), the control unit 117 of the counter 110 performs prescription photography processing (S166) and displays the photographed image of the prescription in the third row of the photo column on the count screen (S167). Note that if the contents of the prescription cannot be confirmed from the photographed image, the prescription photography processing can be retried (S168). After the series of operations is completed, the process is the same as that from step S143 onwards.

[0089] Manual Counting The medicine counting device of the present invention can also perform manual counting processing, which simply counts medicines without linking them to prescription data. To perform this manual counting process, the operator touches the manual counting process button on the menu screen of Fig. 37. When a manual counting instruction is received (S171), the control unit 117 of the counter 110 displays the manual dispensing screen shown in Fig. 42 (S172). The operator specifies the required count number using the numeric keypad on the screen, removes the original bottle to be counted, and either scans it with the barcode reader 118 of the counter 110 or manually enters the NDC on the screen. When scanning is performed (S174), the control unit 117 of the counter 110 performs a process of reading the original bottle barcode (S175). When an NDC is manually input (S176), the control unit 117 searches the medicine master 121 to identify the medicine (S177). Next, the control unit 117 of the counter 110 adjusts the tray size of the counter 110, i.e., the height regulated by the height regulating member 41 and the width regulated by the width regulating member 52, based on the size of the medicine (S178). Next, the control unit 117 of the counter 110 displays a message to load medicines onto the tray (S179). When a count instruction is received (S180), the control unit 117 performs the counting process (S181) and ends the counting process (S182). In manual counting, you can select "All" or "Specify count value" when specifying the count number. If you select "All", the process will end once all the medications placed in the tray have been counted. If you select "Specify count value", the entered quantity will be counted. In this case, if the entered quantity is not reached, the stockout process described above will be carried out. In this stockout process, it is necessary to scan the NDC code of the original bottle and check whether it is the same as the medication being counted.

[0090] In the above embodiment, the medicine supply device is used as a medicine counting device, but it can also be applied to a medicine packing device that stores various types of medicine in cassettes and packages specific medicines according to prescriptions. [Explanation of symbols]
