Description

Technical Field

[0001] The present invention relates to a drug supplying device capable of supplying drugs such as tablets and capsules having different shapes and sizes one by one A drug packaging device equipped with . Background Art

[0002] A drug counting device for counting a large number of drugs is described in Patent Document 1. This drug counting device comprises a central disc member rotated by a first driving means, and an annular member rotated by a second driving means. The rotation axes of the disc member and the annular member are arranged on the same axis so that they are coplanar with each other, and they are rotated in opposite directions to each other by the respective driving means. Further, a drug guide portion is provided on the outer peripheral portion of the annular member so as to extend outward.

[0003] However, in this drug counting device, a large number of drugs that have not been supplied to the drug guide portion are transported in opposite directions on the disc member and the annular member. Therefore, the drugs that have moved from the disc member to the annular member collide with the drugs that have already moved onto the annular member, and the drugs that have moved from the annular member to the disc member collide with the drugs on the disc member.

[0004] On the other hand, Patent Document 2 describes a supplying device that aligns and supplies small articles. This supplying device comprises a disk-shaped first rotating body rotated by a first driving means, and an annular second rotating body rotated by a second driving means. A first rotation axis of the first rotating body is arranged to be inclined at a predetermined angle, and a second rotation axis of the second rotating body is arranged to extend in a vertical direction. The first rotating body is configured such that a portion located at an upper end due to the inclination is positioned at the same height as an inner peripheral portion of the second rotating body. Furthermore, a frame wall surrounding the outer peripheral portion of the first rotating body is integrally provided on the inner peripheral portion of the second rotating body.

[0005] In this Patent Document 2, the supply device moves the supply material from the upper end to the second rotating body as the first rotating body rotates. Then, a restricting body provided on the second rotating body allows only the supply material in a predetermined orientation to pass downstream, while supply material in a different orientation falls from the inner circumference of the second rotating body onto the first rotating body. This prevents the supply materials from colliding with each other.

[0006] However, if this supply device is used to supply drugs, there is a possibility that two or more supplies will pass through the regulating body simultaneously and be supplied to the guide section leading to the outlet in two radially aligned rows. As a result, there is a problem of blockage occurring at the entrance of the guide section. Furthermore, if the drugs are non-circular tablets or capsules containing drugs, even if they are supplied one at a time, depending on their movement orientation, blockage may occur at the entrance of the guide section or within the guide section itself.

[Modes for carrying out the invention]

[0012] Embodiments of the present invention will be described below with reference to the drawings.

[0013] Figure 1 shows a drug counting device using a drug supply device according to an embodiment of the present invention. This drug counting device comprises a drug supply device, a switching valve unit 76, and a central control unit 83 which is a counting means. The mechanism of the drug supply device is automatically adjusted to supply and count various drugs of different shapes and sizes one by one.

[0014] As shown in Figures 1 and 2, the casing 10 of the drug counting device comprises a casing body 11 located on the upper side and a stand 16 located on the lower side. The casing body 11 is a housing that is closed on all four sides and top and bottom, and its front cover 12 has a shape that bulges forward from the stand 16. On the left side of the figure, the front cover 12 is provided with a container mounting section 13 for attaching the drug container 1 to be given to the patient and the collection container 2 for storing the drug. In addition, an upper cover 14 is rotatably attached to the rear side of the casing body 11. This upper cover 14 is provided with an input opening 15 for exposing the inside of the frame 17, which will be described later. The stand 16 is a housing with an open top that positions the casing body 11 on top. This stand 16 is used as needed to position the casing body 11 at a predetermined height so that the containers 1 and 2 attached to the casing body 11 do not come into contact with the table or other surface on which it is placed.

[0015] As shown in Figure 3, the drug supply device comprises a substantially cylindrical frame 17, a disc-shaped first rotating body 23, an annular second rotating body 35, a height restrictor 41 that restricts the height of the supplied drug, a width restrictor 52 that restricts the transport width of the second rotating body 35, and a drug guide section 65 consisting of an inner guide 66 and an outer guide 57. In this embodiment, the width restrictor 52 and the outer guide 57 of the drug guide section 65 are made from a single molded resin part.

[0016] As shown in Figures 3, 4, and 5, the frame 17 has a partition wall 18 that covers the outer periphery of the first rotating body 23 and an outer wall 20 that covers the outer periphery of the second rotating body 35. These are fixed to the upper surface plate of the outer casing body 11, respectively, from above and below. The partition wall 18 is a substantially cylindrical shape that extends from the inner periphery 36 of the second rotating body 35 to the outer periphery of the first rotating body 23, dividing the space between them. A notch 19 is provided in a part of the lower outer periphery of this partition wall 18 to prevent interference with the rotation bracket 30 that fixes the first drive motor 28 of the first rotating body 23. The outer wall 20 is a cylindrical shape that prevents the chemicals on the second rotating body 35 from falling off. A first notch 21 is provided in a part of the upper outer periphery of this outer wall 20, and a second notch 22 is provided in a part of the lower outer periphery. The first notch 21 is for exposing the second rotating body 35 and for positioning the width restricting body 52 and the drug guide section 65. The second notch 22 is for exposing the gear member 38 of the second rotating body 35 from the side. The frame 17 may also have the partition wall 18 and the outer wall 20 integrally provided.

[0017] The first rotating body 23 is disc-shaped and is positioned at an inclination within the partition wall 18 so as to close the bottom of the partition wall 18. That is, as shown in Figures 6A and 6B, the first rotation axis 24 of the first rotating body 23 is positioned at a predetermined angle with respect to the vertical. Multiple protrusions 25 are provided radially on the upper surface of the first rotating body 23 to provide resistance (to prevent rolling) for moving the drug. The outer circumference of the first rotating body 23 is provided with a sloping surface 26 that slopes downward toward the radially outward direction. This sloping surface 26 is positioned at a predetermined inclination angle such that its upper end, the inner circumference, is above the second rotating body 35, and its lower end, the outer circumference, is below the inner circumference.

[0018] A gear 27 is connected to the lower end of the first rotating shaft 24 of the first rotating body 23. This gear 27 meshes with a gear 29 connected to the output shaft of the first drive motor 28, which is the first driving means, and is configured to rotate around the first rotating shaft 24. The first rotating shaft 24 and the first drive motor 28 are mounted on a rotating bracket 30. Guide bearings (not shown) are provided on the side of the rotating bracket 30, and these bearings are engaged with guide grooves of a mounting bracket 31 fixed to the outer casing body 11. Also, as shown in Figures 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 is an angle adjustment means, meshes with this gear piece 32. The rotating bracket 30 can be rotated relative to the mounting bracket 31 by driving this 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, and the tilt angle of the first rotating body 23 can be adjusted. This tilt angle adjustment is configured to be performed using the upper end of the first rotating body 23 as a pivot point.

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

[0020] As shown in Figures 3 and 5, an annular gear member 38 is fixed to the lower surface of the second rotating body 35. The gear 40 of the second drive motor 39, which is the second driving means, meshes with this gear member 38 through the second notch 22 of the outer wall 20. The outer circumference of the gear member 38 is supported by a support member (not shown). As a result, the upper rotating member rotates about the second rotation axis without moving along the second rotation axis.

[0021] The height regulating body 41 is positioned downstream in the rotation (drug transfer) direction relative to the movable part 37 of the second rotating body 35. This height regulating body 41 comprises a height regulating member 42, a mounting member 44, and an operating receiving member 45. As shown in Figures 7A and 7B, the height regulating member 42 is positioned above the second rotating body 35. This height regulating member 42 extends from the outer circumference to the inner circumference 36 of the second rotating body 35 and has a guide surface 43 that is inclined at a predetermined angle along the drug transfer direction. The mounting member 44 is connected to the height regulating member 42 and is for positioning the height regulating member 42 on the second rotating body 35, straddling the width regulating body 52. ​​The operating receiving member 45 is connected to the mounting member 44 and receives power to move the height regulating member 42 up and down via the mounting member 44. The operating receiving member 45 is provided with a screw hole 46 that penetrates vertically for receiving power.

[0022] A screw member 47 passes through the screw hole 46 of the height regulating body 41. This screw member 47 is supported by a bracket fixed to the top plate of the outer casing body 11 so that it can rotate but cannot move along the axial direction. A gear 48 is connected to the lower end of the screw member 47. This gear 48 meshes with a gear 50 of a height adjustment motor 49, which is a height adjustment means. The height adjustment motor 49 rotates the screw member 47, adjusting the height so that the distance between the height regulating body 41 and the top surface of the second rotating body 35 is approximately the same as the drug height. Furthermore, a drug detection sensor 51 is provided downstream of the height regulating body 41 as a second drug detection means to detect the drug that has passed below the height regulating body 41.

[0023] The width restrictor 52 is positioned further downstream in the drug transport direction than the height restrictor 41 and is located on the second rotating body 35. The width restrictor 52 has a rectangular section 53 that extends tangentially to the outer circumference of the second rotating body 35. This rectangular section 53 is positioned so as to bypass the support member 44 of the height restrictor 41 and is able to move in a straight line without interfering with this support member 44. In addition, the width restrictor 52 has a width restrictor section 54 that is continuous with the rectangular section 53 downstream in the drug transport direction. This width restrictor section 54 has a first curved surface section 55 with a diameter larger than the diameter of the inner circumference 36 of the second rotating body 35. As a result, the distance between the width restrictor 52 and the inner circumference 36 of the second rotating body 35 is configured such that only a portion in the circumferential direction has the narrowest transport width. Here, this transport width refers to the width (area) through which the drug can pass from the inner circumference 36 of the second rotating body 35 to the first curved surface section 55. Furthermore, the width regulating section 54 includes a second curved surface section 56 that is connected to the first curved surface section 55 such that the transport width on the downstream side in the drug transport direction gradually widens. The width regulating body 52 has an outer guide 57 that constitutes the drug guide section 65, which is continuous with the width regulating section 54 on the downstream side in the drug transport direction. This outer guide 57 is configured to extend tangentially to the second curved surface section 56 and perpendicular to the rectangular section 53.

[0024] A connecting member 58 is connected to the width restricting portion 54 of the width restricting body 52 so as to extend parallel to the rectangular portion 53. An operating receiving member 59 is connected to this connecting member 58, similar to the height restricting body 41. A screw member 61 passes through the screw hole 60 of this operating receiving member 59, and this screw member 61 is rotatably supported by a bracket fixed to the top plate of the outer casing body 11 so as to be immovable along the axial direction. 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 is a width adjustment means for moving the width restricting body 52 in the horizontal direction, meshes with this gear 62. When the width restricting body 52 is moved outward relative to the second rotating body 35 by this width adjustment motor 63, the transport width between the width restricting portion 54 and the inner circumference 36 of the second rotating body 35, and the distance between the outer guide 57 and the inner guide 66, which will be described later, can be increased. Furthermore, when moved inward relative to the second rotating body 35, the transport width of the second rotating body 35 and the spacing between each guide 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 such that the width between the outer guide 57 and the inner guide 66 is approximately twice (2W) the transport width W between the outer guide 57 and the inner circumference portion 36 of the second rotating body 35. In this embodiment, the transport width W is configured to be half the width of the drug being transported. Note that in the case of a drug with an elliptical or oblong shape in plan view, the drug width refers to the shorter side. Also, the transport width W is not limited to half the drug width, but is preferably between half the drug width and the drug width.

[0025] The drug guide section 65 guides the drug that has passed through the width restricting section 54 of the width restricting body 52 to the drug discharge member 73, which will be described later and is a drug discharge port. As shown in Figures 3 and 7A,B, the drug guide section 65 is positioned on the second rotating body 35 so as to be downstream of the width restricting section 54 of the width restricting body 52 in the drug transport direction. The inner guide 66 constituting the drug guide section 65 is positioned parallel to the radially inward side of the second rotating body 35 relative to the outer guide 57, and is positioned so as to extend tangentially to the inner circumference 36 of the second rotating body 35. The inner guide 66 extends to the drug discharge member 73, and a bracket portion 67 for fixing to the upper plate portion of the outer casing body 11 is provided at its end. The spacing between the guides 57 and 66 constituting the drug guide section 65 is adjusted to approximately the same spacing as the drug width by driving the width adjustment motor 63. Furthermore, 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 circumference 36 of the second rotating body 35, which is on the step between the first rotating body 23 and the second rotating body 35. The inner surface of this inclined edge 68 is an inclined surface 69 that slopes downward.

[0026] As shown in Figure 8, the drug counting device has a drug discharge member 73 located at the outlet of the drug guide unit 65, a detection unit 70 for detecting the drug, a shutter 74 for allowing or denying the discharge of the drug to the detection unit 70, and a switching valve unit 76 for distributing the drug that has passed through the detection unit 70, located below the drug discharge member 73. The drug discharge member 73 constitutes a drug discharge port located on the radially outer side of the second rotating body 35 and guides the drug discharged from the drug guide unit 65 to the detection unit 70.

[0027] The detection unit 70, which is the first drug detection means, has a pair of rectangular cylindrical housings 70A and 70B, as shown in Figures 9(A) and (B). The upper housing 70A has a pair of light-emitting units 71A and 71B on adjacent faces and a pair of light-receiving units 72A and 72B on opposite faces. The lower housing 70B has a pair of light-emitting units 71C and 71D on adjacent faces and a pair of light-receiving units 72C and 72D on opposite faces. Each 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, constitutes one set of optical sensors (line sensors). The two sets of optical sensors (four sets in total) arranged in the two housings 70A and 70B are positioned at predetermined intervals in the axial direction. Furthermore, by arranging each housing 70A and 70B at a phase angle of 45 degrees relative to each other, the detection direction can be made different. Compared to the case where a regular octagonal housing capable of housing all four sets of optical sensors is used, the detection unit 70 configured in this way can be made smaller in plan view (occupied area).

[0028] As shown in Figure 8, the shutter 74 is located inside the outlet side of the drug discharge member 73. This shutter 74 is rotatable by a drive motor 75, which is a discharge permission / denial means, from a discharge stop position extending horizontally to a discharge permission position inclined downwards. In the discharge stop position, it closes the outlet of the drug discharge member 73, preventing the discharge of the drug into the detection unit 70. In the discharge permission position, it opens the outlet of the drug discharge member 73, allowing the discharge of the drug into the detection unit 70.

[0029] The switching valve unit 76 is positioned below the detection unit 70 so as to be located at the container mounting portion 13 of the outer casing body 11. The casing of this switching valve unit 76 has an inverted Y-shaped drug passage 77 that branches into a first passage portion, the dispensing portion 78, and a second passage portion, the recovery portion 79. Steps 78a and 79a are provided at the ends of the dispensing portion 78 and the recovery portion 79 for mounting drug containers 1 and recovery containers 2. Of these, the step 78a of the dispensing portion 78 located on the left side in the figure is provided in three sets so as to be able to mount three types of drug containers 1 with different diameters (volumes). A switching valve is provided inside the drug passage 77 to switch the discharge destination to either the dispensing portion 78 or the recovery portion 79. The switching valve in this embodiment has a pair of oscillating members 80A and 80B that are arranged to extend from the inlet of the drug passage 77 toward the discharge portion 78 and the recovery portion 79. The first oscillating member 80A on the left side of the figure opens and closes the dispensing section 78, and the second oscillating member 80B on the right side of the figure opens and closes the recovery section 79. Elastic parts 81 that can be elastically deformed are provided on the opposing surfaces of these oscillating members 80A and 80B. Each oscillating member 80A and 80B is individually oscillated by its respective driving means, the drive motors 82A and 82B. In this embodiment, the device can move to three positions: the drug dispensing position (first operating position) shown in Figure 10A, the temporary stopping position (second operating position) shown in Figure 10B, and the drug recovery position (third operating position) shown in Figure 10C. In the temporary stopping position, each oscillating member 80A and 80B is rotated to an angle in which their elastic parts 81, 81 come into contact with each other and deform elastically. The oscillating members 80A and 80B may be formed from an elastically deformable material.

[0030] As shown in Figure 11, the drug counting device, including the drug supply device, operates according to commands from the central control unit 83 and counts and supplies the required number of drugs according to the prescription data. As shown in Figure 18, the drug coefficient device is equipped with an auditing desk. The auditing desk is equipped 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 taken by the first camera 89a, the second camera 89b, and a third camera 89c that is located near the drug input port of the drug coefficient device and photographs the area around the moving part 37 from the first rotating body 23 to the second rotating body 35 or the height regulating body 41. Alternatively, the first camera 89a may be made movable so that it also functions as the third camera 89c, thus eliminating the third camera altogether.

[0031] Before dispensing the medication, the operator reads the medication ID (barcode) printed on the medication bottle with a barcode reader 86. Dispensing is only permitted if this medication ID matches the correct medication indicated in the prescription data. This prevents the dispensing of the wrong medication. Next, the operator reads the prescription ID (barcode) printed on the medication container 1 that receives the medication. Dispensing is only permitted if this prescription ID matches the prescription ID indicated in the prescription data. This prevents the mis-selection of medication container 1.

[0032] Next, the operator adjusts the tilt angle of the first rotating body 23 by operating the control panel 84, puts the drug into the drug input space partitioned by the first rotating body 23 and the partition wall 18, inputs the number of drugs to be prescribed, and starts the counting process. In the counting process, the central control unit 83 performs an automatic adjustment (auto-calibration) process for each regulatory body 41, 52 according to the drug, and then performs a counting process to actually count the drugs. In this counting process, the central control unit 83 acts as a counting means that counts the supplied drugs based on detection by the detection unit 70.

[0033] The angle adjustment process of the first rotating body 23 is performed according to the amount of drug to be introduced and the size and shape of the drug. Specifically, when a large amount of drug is introduced, the inclination angle of the first rotating body 23 is made steep (near vertical) so that the storage space formed between the partition wall 18, the first rotating body 23, and the second rotating body 35 is widened. Also, in the case of spherical drugs that do not move to the second rotating body 35 by rolling (rotating) on ​​the upper surface even when the first rotating body 23 is rotated, the inclination angle of the first rotating body 23 is made gentle (near horizontal). This adjusts the arrangement of a large number of drugs on the first rotating body 23 so that the drugs can move to the second rotating body 35. Note that this angle adjustment process may be configured to be automatically adjustable by arranging drug detection means on the moving part 37 of the second rotating body 35. In this case, this angle adjustment process is performed in the first stage of the automatic adjustment process.

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

[0035] It is preferable to store the positions of the height restrictor 41 and the width restrictor 52 in advance for each drug. To this end, first, the barcode of the medicine bottle containing the medicine to be counted is read by a barcode reader 86 installed on the medicine counting device. Also, when a medicine detection sensor 51 installed downstream of the height restrictor 41 detects that the medicine has passed over the height restrictor 41, the restrictive height (or position) of the height restrictor 41 at that time is stored in the memory 87. Simultaneously, the third camera 89c takes a picture of the medicine near the height restrictor 41. Furthermore, when a sensor or detection unit 70 installed downstream of the width restrictor 52 detects that the medicine has passed over the width restrictor 52, the transport width (or position) of the width restrictor 52 at that time is stored in the memory 87. The memory 87 stores the restrictive height of the height restrictor 41, the transport width of the width restrictor 52, and the medicine read by the barcode reader in association. Furthermore, the stored information for the regulated height and transport width may be displayed on the monitor 88 for the operator to confirm, and may be made to fine-tune it as needed, overwriting the regulated height and transport width with the fine-tuned values. This allows the operator to read the drug type ID (barcode) printed on the drug bottle with the barcode reader 88, and if the regulated 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 these values ​​and drug counting can begin. Also, if the regulated height of the height regulator 41 and the transport width of the width regulator 52 associated with the drug are not stored, such as with new drugs, the operation to acquire these regulated heights and phase widths is performed as described above.

[0036] In the counting process, the rotation speed of each rotating body 23, 35 is increased to be faster than in the automatic adjustment process, enabling high-speed counting. When the amount of drug dispensed approaches the set number, the rotation speed of the second rotating body 35 is reduced. This slows down the discharge speed from the drug guide section 65. When the dispensed amount of the set number of drugs has been counted, as shown in Figure 10B, the oscillating member 80A located on the side of the dispensing section 78 is rotated towards the side of the recovery section 79, closing both the dispensing section 78 and the recovery section 79. In this temporary position, the elastic parts 81, 81 are in a pressure-contact state, elastically deformed by contact. In this state, the dispensed drug can be temporarily held on the upstream side of the pair of oscillating members 80A, 80B. Next, as shown in Figure 10C, the oscillating member 80B located on the side of the recovery section 79 is rotated towards the oscillating section, opening the side of the recovery section 79. As a result, the chemical temporarily accumulated on the upstream side of the pair of oscillating members 80A and 80B is ejected towards the recovery section 79 when the elastic part 81 on the dispensing section 78 side elastically returns to its original position. Therefore, it is possible to reliably prevent an excess of chemical from being dispensed to the dispensing section 78 side. Finally, the rotation speed of the rotating bodies 23 and 35 is increased to discharge all the chemical in the frame 17 into the recovery container 2.

[0037] The counting by the central control unit 83 is performed based on input signals from four sets of optical sensors (eight sensors per set) of the detection unit 70. In this embodiment, the detection unit 70 detects the drug falling by its own weight (constant speed) due to discharge from four different directions using line sensors 71A, 72A~71D, and 72D. As a result, the volume, including the shape such as width and height of the passed drug, can be determined from the input values ​​from the light receiving units 72A~72D. Specifically, the width of the drug from four different directions is determined from the input from each light receiving element of each light receiving unit 72A~72D. Furthermore, since the vertical height of 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 are different, the horizontal cross-sectional shape of the falling drug can be accurately determined based on the width determined by each light receiving unit 72A~72D, taking into account the detection time difference due to falling. In addition, by repeatedly performing this determination at predetermined intervals, the horizontal cross-sectional shape for each time period can be determined. Based on the horizontal cross-sectional shape of all the drugs at each time interval, the volume (3D shape) including the shape of the falling drug can be determined. Furthermore, the central control unit 83 stores information on all drugs of different shapes and sizes. Therefore, this drug information is compared with the determined shape and volume to determine (confirm) the type of drug being counted. Based on this confirmed drug information, the number of drugs dispensed is then counted. As a result, it is possible to detect cases where two drugs pass together. Thus, highly accurate counting can be achieved. Once the dispensing of the medication is complete, the opening of the medication container 1 is pointed towards the first camera 89a on the auditing stand shown in Figure 18, and the medication dispensed into the medication container 1 is photographed as shown in Figure 19(A). Subsequently, the label on the side of the medication container 1 is pointed towards the second camera 89b, and the prescription data is photographed as shown in Figure 19(B). Next, the captured images in Figure 19(A), Figure 19(B), and the image of the medication in the process of being dispensed, as shown in Figure 19(C), captured by the third camera are simultaneously displayed on the monitor 88 to audit whether the medication according to the prescription data has been dispensed.

[0038] Next, we will specifically explain the drug transfer operation of a disc-shaped tablet X, which is one of the drugs, by the drug supply device. Note that this transfer operation of the disc-shaped tablet X is the same even if the drug is spherical.

[0039] As shown in Figures 12(A) and (B), when the first rotating body 23 is rotated, the tablet X rests on its upper surface and rotates, and is moved radially outward by centrifugal force. The tablet X on the first rotating body 23 then moves onto the second rotating body 35 via a moving part 37 located at approximately the same height as the second rotating body 35.

[0040] The tablets X that have moved onto the second rotating body 35 are moved toward the drug guide section 65, and their downstream movement is restricted by the height restrictor 41. For example, if tablets X are moving while stacked vertically, the upper tablet X will come into contact with the guide surface 43 of the height restrictor 41, causing it to fall onto the second rotating body 35 or onto the first rotating body 23 from the inner circumference 36.

[0041] Tablet X that has passed the height restrictor 41 is moved toward the inner circumference 36 of the second rotating body 35 by contacting the first curved surface 55 of the width restrictor 52, which restricts the transport width. Since the transport width by the second rotating body 35 is halved by the first curved surface 55 of the width restrictor 52, only tablets X that are in contact with the width restrictor 52 can pass toward the downstream side of the width restrictor 52. That is, if 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 circumference 36 of the second rotating body 35 onto the first rotating body 23. Also, even if the tablets X are not aligned radially, tablets X whose center of gravity is located inside the inner circumference 36 of the second rotating body 35 will also fall from the inner circumference 36 onto the first rotating body 23. Therefore, other tablets X that are not in contact with the width restrictor 52 are not transported toward the downstream side.

[0042] The tablets X that have passed through the first curved surface portion 55 of the width restricting body 52 are transported in a stable state in the area of ​​the second curved surface portion 56, where the transport width is wider. They are then transported between the inner guide 66 and the outer guide 57 of the drug guide portion 65, and are moved toward the exit side in an aligned state, and discharged to the detection unit 70. At this time, tablets X1 that protrude inward from the inner circumference portion 36 of the second rotating body 35 come into contact with the end of the inner guide 66, and are guided between it and the outer guide 57, or fall from the inner circumference portion 36 onto the first rotating body 23. Only the tablets X that have passed through this drug guide portion 65 are supplied to the detection unit 70 through the drug discharge member 73, which is the drug discharge port.

[0043] Next, we will specifically explain the drug transport mechanism of capsule Y, which differs in shape and size from the disc-shaped tablet X. Note that this transport mechanism for capsule Y is the same even for non-circular tablets, such as oval-shaped tablets.

[0044] As shown in Figures 13(A) and (B), when the first rotating body 23 is rotated, the capsule Y rests on its upper surface and rotates, and is moved radially outward by centrifugal force. Then, the capsule Y on the first rotating body 23 is transferred onto the second rotating body 35 by a moving part 37 located at the same height as the second rotating body 35.

[0045] The capsule Y that has been transferred to the second rotating body 35 is moved toward the drug guide section 65, and its downstream movement is restricted by the height restrictor 41. The capsule Y, which is moving in a stacked state, is either dropped onto the second rotating body 35 or falls from the inner circumference 36 onto the first rotating body 23.

[0046] As the capsule Y passes through the height restrictor 41, it comes into contact with the first curved surface 55 of the width restrictor 52, which restricts the transport width. This causes it to move towards the inner circumference 36 of the second rotating body 35, and its longitudinal orientation (posture) is corrected so that it extends along the drug transport direction. Only the capsule Y that is in contact with the width restrictor 52 passes downstream of the width restrictor 52, while the capsule Y that is not in contact with the width restrictor 52 falls from the inner circumference 36 of the second rotating body 35 onto the first rotating body 23. Furthermore, capsule Y1 whose posture could not be corrected by contact with the first curved surface 55 cannot maintain balance because the transport width by the second rotating body 35 is approximately half that of the capsule Y1. As a result, its center of gravity is located inside the inner circumference 36 of the second rotating body 35, and it falls from the inner circumference 36 of the second rotating body 35 onto the first rotating body 23.

[0047] The capsules Y that have passed through the first curved surface 55 of the width restricting body 52 are transported in a stable state in the area of ​​the second curved surface 56, where the transport width is wider. They are then transported between the inner guide 66 and the outer guide 57 of the drug guide section 65, and are moved toward the exit side in an aligned state, and discharged to the detection section 70. At this time, capsules Y2 whose orientation could not be completely corrected come into contact with the end of the inner guide 66, thereby correcting their orientation and being guided between it and the outer guide 57, or they fall from the inner circumference 36 onto the first rotating body 23. Only the capsules Y that have passed through this drug guide section 65 are supplied to the detection section 70 through the drug discharge member 73, which is the drug discharge port.

[0048] Since the capsule Y is not flat like the disc-shaped tablet X, it makes point or line contact with the second rotating body 35 and is prone to rotation as it moves along the second rotating body 35. Therefore, tablets that are not flat like the capsule Y may change orientation on the second rotating body 35 after passing the width restricting body 52 and before reaching the tablet guide portion 65, and may fall onto the first rotating body 23. For this reason, as shown in Figures 15(A) to (C), it is preferable to provide an annular rib 35a that protrudes upward on the inner periphery of the second rotating body 35. The rib 35a may have a triangular radial cross-section with an inner surface flush with the inner surface of the second rotating body 35, a pointed upper end, and a linearly inclined outer surface, as shown in Figure 15(A); a concave curved and inclined outer surface, as shown in Figure 15(B); or a rectangular radial cross-section with an inner surface flush with the inner surface of the second rotating body 35, a flat upper end, and a vertical outer surface, as shown in Figure 15(C). By providing such a rib 35a, non-flat tablets will come into contact with the upper surface of the second rotating body 35 and the rib 35a at two points, as shown in Figure 15(A), making it difficult for them to rotate on the second rotating body 35 and preventing them from falling onto the first rotating body 23.

[0049] Thus, in the drug supply device of the present invention, the height restrictor 41 and the width restrictor 52 align the drugs one by one and supply them to the drug guide section 65. Therefore, the drugs can be reliably passed through the drug guide section 65 one by one and supplied to the outside from the drug discharge member 73 without causing problems such as clogging. Furthermore, since the numerous drugs being transported are not blocked by each restrictor 41, 52 and the drug guide section 65, but are dropped onto the first rotating body 23, clogging at the restrictors 41, 52 can be reliably prevented, and collisions between numerous drugs can be prevented. Therefore, the occurrence of cracking or chipping of the drugs can be reliably prevented. In particular, since the width restrictor 52 restricts the transport width of the second rotating body 35 to 1 / 2 of the drug width, drugs that are not circular in plan view can only pass through if their longitudinal direction is extended along the drug transport direction. Therefore, clogging at the entrance of the drug guide section 65 can be reliably prevented.

[0050] Furthermore, since the height regulation by the height regulation body 41 and the transport width of the second rotating body 35 by the width regulation body 52 are configured to be adjustable, it is possible to supply various types of drugs with different shapes and sizes. In addition, the width regulation body 52 and the outer guide 57 of the drug guide section 65 are provided as an integrated unit, and they can be adjusted simultaneously, improving the workability of adjustments and reducing the number of parts. Moreover, in this embodiment, the regulation bodies 41 and 52 are configured to be automatically adjusted, so the operator does not need to make any adjustments, greatly improving the convenience of use.

[0051] Furthermore, since the inner guide 66 of the drug guide section 65 is provided with an upwardly inclined inclined edge 68, it is possible to reliably prevent the drug, which is transported while protruding inward from the inner circumference 36 of the second rotating body 35, from getting stuck at the entrance of the drug guide section 65. This configuration is particularly effective because it can correct the posture or allow the drug, which is not circular in plan view, to fall onto the first rotating body 23 when it is transported at a slight inclination. Moreover, since the inclination angle of the first rotation axis 24 of the first rotating body 23 is adjustable, the drug can be reliably transported to the moving section 37 by the rotation of the first rotating body 23 and moved onto the second rotating body 35.

[0052] Furthermore, the drug counting device using the drug supply device reliably discharges drugs of different shapes and sizes one by one to the outside, detects the drugs with the detection unit 70, and reliably counts them with the central control unit 83. Therefore, a predetermined number of drugs can be reliably dispensed and prescribed to the patient. In addition, the switching valve unit 76 located in the container mounting section 13 has a dispensing section 78 for which the drug container 1 to be given to the patient is placed, and a recovery section 79 for which the recovery container 2 is placed, thereby improving the work efficiency related to prescription. Moreover, when the number of drugs to be prescribed is counted, the oscillating members 80A and 80B are operated to a temporary position that closes both the dispensing section 78 and the recovery section 79, thereby preventing more drugs than the predetermined number from being dispensed into the drug container 1. Furthermore, when the position is later set to the recovery position for the recovery container 2, the elastic part 81 elastically returns to its original position, so that the drugs held on the upstream side of the pair of oscillating members 80A and 80B are ejected to the recovery section 79, thereby reliably preventing excessive dispensing into the drug container 1 through the dispensing section 78.

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

[0054] <Other Embodiments> It should be noted that the drug counting device of the present invention is not limited to the configuration of the above embodiment, and various modifications are possible. In particular, various modifications are possible for the drug supply device.

[0055] For example, in this embodiment, the height restriction on the second rotating body 35 is adjustable by the height restriction member 41, and the transport width of the second rotating body 35 is adjustable by the width restriction member 52. However, it may also be a fixed type that cannot be adjusted. Even in this case, as long as the drug is at a height that can pass between the second rotating body 35 and the height restriction member 41, and is wide enough to pass through the transport width of the second rotating body 35 restricted by the width restriction member 52, drugs of different shapes and sizes can be transported and supplied. Therefore, the versatility of drug supply can be increased.

[0056] Furthermore, in the above embodiment, the transport width by the second rotating body 35 can be changed by the width restrictor 52, but the width restrictor 52 may be omitted. Even in this case, if the drug is circular in plan view, drugs of different shapes and sizes, such as spherical or disc-shaped drugs, can be transported and supplied. In this case, the drugs that have passed through the height restrictor 41 are supplied to the entrance of the drug guide section 65 in two radial rows. However, since the drug guide section 65 has a pair of guides 57 and 66 spaced approximately the same as the drug width, drugs located on the inner circumference 36 side of the second rotating body 35 come into contact with the inner guide 66 and fall from the inner circumference 36 of the second rotating body 35 onto the first rotating body 23. Therefore, clogging of the drugs at the entrance of the drug guide section 65 is prevented, and the drugs can be reliably discharged one by one to the outside.

[0057] Furthermore, the height regulating body 41 is adjustable by moving it vertically, and the width regulating body 52 is adjustable by moving it horizontally, but as shown in Figure 14A, they may also be adjustable by rotation. Moreover, the width regulating body 52 has an outer guide 57 which constitutes the drug guide section 65 integrated into it, but as shown in Figure 14B, it may also have a separate outer guide 57 which can be adjusted individually. In this case, the width regulating body 52, excluding the 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 rotating body 23 is positioned to be tilted at a predetermined angle, and the second rotating body 35 is positioned horizontally. However, the first rotating body 23 may be positioned horizontally, and the second rotating body 35 may be positioned to be tilted at a predetermined angle. Of course, both the first rotating body 23 and the second rotating body 35 may be tilted at a predetermined angle. In other words, the rotation axes of the first rotating body 23 and the second rotating body 35 should intersect at an angle that allows the drug to move.

[0059] Furthermore, in the above embodiment, the first rotating body 23 and the second rotating body 35 are configured to rotate in the same direction, but they may be configured to rotate in opposite directions. In addition, in the above embodiment, the partition wall 18 is fixed and not rotatable, but it may be configured to be rotatable. In this case, the partition wall 18 may rotate integrally with the second rotating body 35, or it may rotate independently on the same axis. Furthermore, in the above embodiment, the inner guide 66 of the drug guide section 65 is positioned at the edge of the inner circumference 36 of the second rotating body 35, but it may be positioned radially outward from the edge of the inner circumference 36, as long as it is in a position where the drug with an off-center center of gravity can be dropped from the inner circumference 36 onto the first rotating body 23.

[0060] In the above embodiment, the first rotating body 23 and the second rotating body 35 are fixed in the axial direction, and the heights of the first rotating body 23 and the second rotating body 35 are set to approximately the same height in the moving section 37 through which the drug moves from the first rotating body 23 to the second rotating body 35. However, the amount of drug transferred can be adjusted by moving the first rotating body 23 in the axial direction. If there is a large amount of drug, the first rotating body 23 is moved downward, causing the drug to form a mass on the first rotating body 23 and move to the moving section 37, where the drug at the top of the mass is transferred to the second rotating body 35. When the amount of drug decreases and there is no more drug on the second rotating body 35, the first rotating body 23 is moved upward to approach the second rotating body 35, making it easier for the drug to move from the first rotating body 23 to the second rotating body 35.

[0061] In the above embodiment, the distance of the second rotating body 35 between the moving part 37, which moves the drug from the first rotating body 23 to the second rotating body 35, and the height restrictor 41 is constant, but this distance may be variable. This can be done by changing the inclination direction of the first rotating body 23. When there is a lot of drug, if the distance from the moving part 37 to the height restrictor 41 is short, a lot of drug will get stuck or fall at the height restrictor 41, and discharge will take a long time, so the position of the moving part 37 is moved farther away from the height restrictor 41 so that the distance from the moving part 37 to the height restrictor 41 is long. When there is a little drug, if the distance from the moving part 37 to the height restrictor 41 is long, it will take a long time to reach the height restrictor 41, so the position of the moving part 37 is moved closer to the height restrictor 41 so that the distance from the moving part 37 to the height restrictor 41 is short.

[0062] As shown in Figure 16(A), a lid 84 that can be opened and closed may be provided at the open end of the recovery section 79, which is the second passage of the drug passage 77, and a spring 85 may be used to bias the open end in the closing direction, so that when the mouth of the recovery container 2 presses the lid 84, the lid 84 opens and the mouth of the recovery container 2 is positioned below the open end of the recovery section 79. This allows the drug to be stored in the recovery section 79, which is closed by the lid 84, and the stored drug to be collected into the recovery container 2 all at once. Alternatively, a holding mechanism for holding the drug container 1 may be provided in the drug supply device, so that the drug dispensed from the dispensing section 78 can be dispensed into the drug container 1 without having to hold the drug container 1 by hand.

[0063] The operator visually confirms whether all the medication supplied onto the first rotating body 23 has been dispensed. However, there is a risk that the operator may mistakenly believe that all the medication has been dispensed even if some medication remains undispensed. In this case, if a different medication is supplied to the first rotating body 23 for counting the next medication, the different medications will be mixed, leading not only to counting errors but also to the possibility of supplying the wrong medication to the patient, potentially resulting in a medical accident. Therefore, after the counting of the medication is complete and before supplying the next medication, the second rotating body 35 is reversed for a predetermined time. As a result, even if any medication remains on the second rotating body 35, particularly between the inner guide 66 and the outer guide 57, the medication will fall onto the first rotating body 23 due to the width restrictor 52. After this, the outer guide 57 is moved as far inward as possible to close the tablet guide section 65, and the height restrictor 41 is raised as far as possible. The raising of the height restrictor 41 may be performed before the movement of the outer guide 57. Subsequently, the first rotating body 23 and the second rotating body 35 are rotated forward. As a result, the medication on the first rotating body 23 moves onto the second rotating body 35 and passes the height restrictor 41, but falls onto the first rotating body 23 due to the width restrictor 52, and this process is repeated. At this point, if it is detected that the medication has passed the height restrictor 41 or the width restrictor 52, a warning sound can be emitted to notify that there is any medication remaining that has not been dispensed. The timing of the reversal of the second rotating body 35 is preferably, for example, after the lid 84 of the recovery section 79 of the second passage has changed from open to closed and the drug stored in the recovery section 79 has been recovered.

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

[0065] In the above embodiment, there is an audit function that verifies the drug type ID and prescription ID, but an inventory support function may also be provided that verifies only the drug type ID and records this drug type ID and the count value of the drug. The inventory support function allows the pharmacy to periodically check the inventory of drugs used in the pharmacy outside of business hours. Furthermore, the system may have a counting function that simply counts the quantity of medication without verifying either the drug type ID or the prescription ID.

[0066] If the tip of the inner guide 66 in the above embodiment (the tip on the upstream side in the rotation direction of the second rotating body) is higher than the upper surface of the second rotating body 35, the drug being transported on the second rotating body 35 may collide with the tip of the inner guide 66 and be damaged. Therefore, it is preferable that the tip of the inner guide 66 be located inside the inner periphery of the second rotating body 35 and lower than the upper surface of the second rotating body 35, as shown in Figure 20. Note that in Figure 20, unlike the above embodiment, the second rotating body rotates clockwise in the figure. It is also preferable to provide a protruding portion 66a from the lower end of the inner guide 66 toward the inner periphery of the second rotating body 35 to fill the gap between the lower end of the inner guide 66 and the inner periphery of the second rotating body 35. This prevents the drug that hits the inclined surface 69 and is returned onto the second rotating body 35 from falling through the gap between the lower end of the inner guide 66 and the inner periphery of the second rotating body 35.

[0067] <Lifting and lowering mechanism for the first rotating body> In the above embodiment, the first rotating body 23 is fixed in a vertical position relative to the second rotating body 35. In this case, the capacity of the drug supply space on the first rotating body 23 is limited. Therefore, the first rotating body 23 may be provided so as to be able to move up and down relative to the second rotating body 35. The mechanism for moving up and down this first rotating body 23 will be described below.

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

[0069] A cam cylinder 99, with a cam surface 98 formed at its upper end, is rotatably mounted on the base plate 94 of the main body of the device. A roller 92 of the movable frame 90 is rotatably mounted on the cam surface 98. The cam surface 98 consists of a first inclined surface 98a that rises at an angle of approximately 20° from the lowest first point P1, a second inclined surface 98b that descends at an angle of approximately 60° from the uppermost second point P2 of the first inclined surface 98a, a third inclined surface 98c that rises at an angle of approximately 20° from the third point P3 of the second inclined surface 98b, and a fourth inclined surface 98d that descends at an angle of approximately 60° from the uppermost 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 lowest first point P1 and third point P3, the first rotating body 23 supported by the movable frame 90 is in the lowest position, and when the rollers 92 are located at the highest second point P2 and fourth point P4, the first rotating body 23 is in the highest position. The cam cylinder 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 the lifting motor 104 via a worm 102 and a drive gear 103. When the cam cylinder 99 rotates due to the drive of the lifting motor 104, the rollers 92 of the movable frame 90 roll along the cam surface 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 rapidly descend from the highest second point P2 and fourth point P4. Alternatively, a rack and pinion mechanism can also be used instead of this 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 part 18a and a roughly conical upper part 18b. The lower part 18a of the partition wall 18 is an elliptical cylinder that accommodates the inclined first rotating body 23 with the smallest possible gap. The upper end of the lower part 18a is an elliptical inclined to follow the outer circumference of the first rotating body 23 at its highest position and connects to the lower end of the upper part 18b. The part of the lower end of the upper part 18b that faces the highest position of the inclined first rotating body 23 coincides with the upper end of the lower part 18a, and the part that faces the lowest position of the inclined first rotating body 23 extends diagonally upward so as to move outward from the upper end of the lower part 18a. The upper end of the upper part 18b is circular so as to follow the inner circumference of the second rotating body 35.

[0071] On the inner surface of the upper part 18b of the partition wall 18, opposite the lowest position of the inclined first rotating body 23, as shown in Figure 23(A), a tablet rise suppression surface 105 is formed, which is inclined upward from the lower end to approach the first rotating body 23, and a tablet drop guide surface 106 is formed, which is inclined downward from the upper end to approach the first rotating plate 23. The tablet rise suppression surface 105 pushes the tablets that have accumulated on the outer circumference as the first rotating body 23 rotates toward the center of the first rotating body 23, thereby preventing these tablets from riding up onto the upper second rotating body 35 and merging with the tablets being transported on the second rotating body 35, 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 a need to suppress the upward movement of the tablet. Rather, the tablet must be allowed to move upward towards the tablet movement section 37 from the first rotating body 23 to the second rotating body 35. Therefore, as shown in Figure 23(B), the inclination of the tablet upward movement suppression surface 105 is gentle.

[0072] The operation of the lifting mechanism of the first rotating body 23 will now be described. When operating the lifting mechanism of the first rotating body 23, a drug detection sensor 51 is used to detect the drug being transported on the second rotating body 35. The drug detection sensor 51 is provided on the outer wall 20 surrounding the second rotating body 35. A recess 107 of a size that prevents tablets from entering is provided on the inner surface of the outer wall 20, and a hole 108 is provided at the bottom of this recess 107, and a lens 109 that transmits light from the drug detection sensor 51 is embedded in this hole 108. As a result, tablets do not come into contact with the lens 109, and thus it is possible to prevent the tablets from coming into contact with the lens 109 and damaging it while being transported on the second rotating body 35.

[0073] When supplying the drug to the first rotating body 23, the first rotating body 23 is in its lowest position. As the first rotating body 23 and the second rotating body 35 rotate, the tablets on the first rotating body 23 accumulate and bulge out on the outer circumference, move from the first rotating body 23 through the moving part 37 onto the second rotating body 35, and are transported and discharged on the second rotating body 35 as described above. As the drug is discharged sequentially, the amount of drug on the first rotating body 23 decreases, making it impossible for the drug to move from the first rotating body 23 through the moving part 37 onto the second rotating body 35, and thus there is no more drug to be transported on the second rotating body 35. As a result, the drug detection sensor 51 no longer detects the drug being transported on the second rotating body 35, so the first rotating body 23 is moved upward to approach the second rotating body 35. This causes the drug on the first rotating body 23 to move from the first rotating body 23 through the moving part 37 onto the second rotating body 35, and the drug detection sensor 51 detects the drug being transported on the second rotating body 35, so the upward movement of the first rotating body 23 is stopped. This allows the discharge of the drug to continue. By repeating this process, all the drug on the first rotating body 23 can be discharged. When supplying a drug onto the first rotating body 23, the first rotating body 23 is lowered and moved away from the second rotating body 35 in order to secure space for the drug to be contained.

[0074] The lifting and lowering mechanism for the second rotating body 35 is not limited to the above embodiment; as shown in Figure 26, the first rotating body 23 may be moved up and down parallel to its first rotation axis 24. Furthermore, as shown in Figure 27, the first rotating body 23 may be moved up and down along an arc S centered on a point O in the plane formed by the first rotation axis 24 of the first rotating body 23 and the second rotation axis (not shown) of the second rotating body 35. In this case, point O, which is the center of the arc, can be arbitrary, but it is preferable that the highest position of the first rotating body 23 be on the side of the center of the arc. As a result, when the first rotating body 23 is moved downward along the arc, the inclination of the first rotating body 23 increases. In general, the more pharmaceutical material is filled on the first rotating body 23, the easier it is for the top surface of the pharmaceutical material to become horizontal. When the top surface of the pharmaceutical material is horizontal, the top surface of the pharmaceutical material, which is above the lowest position of the first rotating body 23, reaches the inner guide 66 of the second rotating body 35, and mixes with the pharmaceutical material being transported in a single line by the inner guide, causing a problem of pharmaceutical material clogging. However, as shown in Figure 27, if the inclination of the first rotating body 23 that has moved downward is large, even if a large amount of drug is placed on the first rotating body 23, the upper surface of the drug group will not easily become horizontal. As a result, the upper surface of the tablet group on the first rotating body 23 will be lower than the second rotating body 35 near the inner guide 66, and the aforementioned problem of clogging due to mixing with the drug being transported on the second rotating body 35 can be avoided.

[0075] <Drug supply system> A drug supply system that processes the counting operation of the drug counting device (hereinafter simply referred to as counter 110) of the present invention in conjunction with prescription data will be described with reference to the block diagram in Figure 28, the flowchart in Figures 29-36, and the screen diagrams in 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 and packaging devices. A pharmacist is stationed at the host system 111111 to perform audits and other tasks, while an operator (pharmaceutical technician) is stationed at the counter 110 to operate it.

[0076] The host system 111 is a system that dispenses and supplies necessary medications to patients based on patient prescription data. As shown in Figure 28, the host system 111 includes a control unit 112 that communicates data with a counter 110 and other medication dispensing and packaging devices, an audit unit 113 that verifies the medications to be supplied to patients against prescription data, a prescription printer 114 that prints prescriptions according to the prescription data, a label printer 115 that prints labels to be attached to vials according to the prescription data, and a prescription master 116 that stores prescription data.

[0077] The counter 110 includes a control unit 117 that controls the operation of the counter 110 and communicates data with the control unit 112 of the host system 111, a barcode reader 118 that reads barcodes on prescriptions, original drug bottles, and vials, a tray imaging camera 119 (similar to the third camera 89c in the above embodiment) that photographs a drug on the counter 110's tray (referring to the drug storage area mainly composed of the first rotating body 23, the second rotating body 35, and the partition wall 18 in the above embodiment), and a vial / prescription imaging camera 120 that photographs the vial and prescription supplied by the patient. Furthermore, the counter 110 includes a drug master 121 that stores the names, shapes, and sizes of various drugs; a vial master 122 that stores the size of the vial and the number of drugs contained in it; an image data master 123 that stores images captured by the tray camera 119 and the vial / prescription camera 120; a communication data master 124 that stores communication data for transmission and reception with the control unit 112 of the host host system 111; and a touch panel operation display panel 125.

[0078] Power-on and login process As shown in Figure 29, when the operator turns on the power to the counter 110 (S101), the control unit 117 starts the application, waits for a login from the host system 111, starts the web service host (S102), and initializes the counter 110 (S103). On the other hand, on the host system 11 side, when a pharmacist logs into the host system 111 based on the power-on of the counter 110 (S201), the control unit 112 on the host system 111 side performs user authentication (S202) and sends 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 sends 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). Thus, the counter 110 side cannot perform counting processing linked to prescriptions unless it receives a login request from the host system 111 side.

[0079] Upon logging in, the operation display screen of the counter 110 shows the menu screen shown in Figure 37. The menu screen is a touch panel and includes a "Counting for Rx" button that performs counting in conjunction with prescriptions (Rx), a "Counting for manual" button that performs counting of the required amount of medication without being linked to a prescription, a "Master Maintenance" button for adding or modifying medications in the medication master 121, and an "Advanced Setting" button for configuring the environment, etc.

[0080] Drug prescription processing by counter When the operator on the counter 110 side touches the prescription counting processing button, the prescription scan waiting screen shown in Figure 38 is displayed (S106). Furthermore, when the operator issues a prescription issuance instruction to the host system 111, the control unit 112 of the host system 111 receives the prescription issuance instruction (S206), processes the prescription issuance, and prints it using the prescription printer 114 (S207). As shown in Figure 38, the prescription scan waiting screen of the counter 110 instructs the operator to scan the prescription. 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 prescription reading processing (S108) and displays the count screen shown in Figure 39 (S109). Next, the control unit sends 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 an Rx data request from the counter 110 (S208), it sends an Rx data response along with the prescription data (S209). When counter 110 receives an Rx data response (S111), it stores the received data in the communication data master 124 (S112), and as shown in the figure, displays the prescription data (prescription number (Rx), patient name (Patient), drug code and name, and requested quantity (Request)) on the count screen (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 drug master 121 for the size of the drug corresponding to the prescription and adjusts the tray size of the counter 110 based on the size of this drug (S115). The tray size is the height restricted by the height restrictor 41 and the transport width of the second rotating body 35 by the width restrictor 52, as described above. As shown in Figure 39, the count screen instructs the operator to scan the stock bottle, so the operator takes out the stock bottle corresponding to the drug name in the prescription data and scans it with the barcode reader 118 of the counter 110. When the scan is performed (S116), the control unit 117 of the counter 110 performs a stock bottle barcode reading process (S117), checks whether the drug in the stock bottle is the drug to be counted (S118), and if correct, displays "OK" in the "Check a Stock Bottle" item in the "Check" column of the count screen in Figure 39 and instructs the operator to put in the drug (S119). Once the "OK" indicator is displayed and an instruction to dispense the medication is given, the operator dispenses the medication from the original bottle into the tray on counter 110.

[0082] Next, the control unit 117 of the counter 110 issues a label issuance instruction to the host system 111 (S120). When the control unit 112 of the host system 111 receives the label issuance instruction from the counter 110 (S210), it issues a label with prescription data printed on a blank label using the label printer 115 (S211). The operator at the counter receives the issued label and attaches it to the vial. The control unit 117 of the counter 110 instructs the count screen to scan the label (S121). As a result, the operator scans the label attached to the vial using the barcode reader 118 of the counter 110. When a 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 correct, displays "OK" in the "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 Figure 40 (S128). The operation of the counter 110 continues until the drug sensor 51 detects that the drug on the first rotating body 23 has moved to the second rotating body 35, been transported on the second rotating body 35, and reached the height regulating body 41. The tray image captures the image of the drug that has stopped at this height regulating body 41 in real time. The operator confirms that the drug in the tray image displayed on the camera image capture screen is the same as the image of the prescribed drug (S129), and if the drug markings cannot be confirmed, the operation of the counter 110 is retried and repeated until confirmation is possible. The drug verification and retry instructions at this time are performed by a pharmacist in the audit department 113 of the host system 111. Once the image is verified (S129), "OK" is displayed in the "Capture Tray" item of the "Check" column on the count screen in Figure 39, and the tray image, as shown on the right side (Still picture) of Figure 40, is saved to the image data master 123 (S130).

[0084] When the tray image shows "OK", the operator places the vial into the dispensing unit 78 of the counter 110. When the control unit 117 of the counter 110 detects that the vial has been placed (S131), it performs a counting process (S132). When the counting is complete, the control unit 117 of the counter 110 displays the counted number in the center of the count screen and displays "OK" in the Count item of the Check column. When the count shows "OK", the count screen instructs the operator to scan the stock bottle from which to collect any remaining medication in the tray, so the barcode reader 118 of the counter 110 scans the stock bottle containing the medication. When the scan is performed (S133), the control unit 117 of the counter 110 reads the stock bottle barcode (S134), checks whether the stock bottle is correct or not (S135), and if it is correct, performs the medication collection process (S136).

[0085] For safety reasons, it is optional to recount the medications that have been counted by the counter 110 and placed in the vials. However, if the operator instructs recounting (S137) and the counter 110 detects the placement of the vials (S138), the control unit 117 of the counter 110 performs the recounting process (S139). Once the recounting is complete, the operator attaches a cap to the vial and places the vial and prescription below the vial / prescription camera 120, with the vial placed on top of the prescription. The operator then instructs the counter 110 to take a picture of the vial and prescription on the count screen. Upon receiving the instruction to take a picture of the vial and prescription (S140), the control unit 117 of the counter 110 performs the vial / prescription photography process (S141) and displays the captured image of the vial and prescription in the second row of the photo section on the count screen (S142). If the label on the vial or the contents of the prescription cannot be confirmed from the captured image, the vial / prescription photography process can be retried. When the host system 111 confirms that the pharmacist has completed the series of tasks (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 tasks.

[0086] Dividing the vial The control unit 117 of the counter 110 selects the size of the vial based on the prescription data. However, if the prescribed amount cannot be contained in a single vial, multiple vials (in the example in Figure 41, three 40DR vials) are displayed in the Split Vial section, as shown in the screen of Figure 41. The system indicates that 40 units of medication will be contained in two vials and 20 units in the remaining vial. The system then counts and places the predetermined quantities of medication into the vials accordingly.

[0087] Processing when stock shortages occur During the counting process, if the medication in the tray runs out before the predetermined amount of medication is counted up, i.e., if the tablet detection sensor stops detecting medication, a shortage state occurs. In this case, medication needs to be added to the tray. As shown in Figure 34, when it is determined that a shortage has occurred (S151), the control unit 117 of the counter 110 temporarily stops dispensing and counting the drug (S152) and instructs the operator to scan a new bottle. The operator takes out a new bottle corresponding to the drug name in the prescription data and scans it with the barcode reader 118 of the counter 110. Once the scan is performed (S153), the control unit 117 of the counter 110 performs a barcode reading process on the new bottle (S154) and checks whether the drug in the new bottle is the drug to be counted (S118). The counting process then continues (S132).

[0088] Prescription processing for liquid and boxed medications other than tablets. Liquid medications supplied in bottles or boxes cannot be counted by counter 110. However, counter 110 can be used to conduct audits in conjunction with prescriptions. In the case of prescriptions for liquid or boxed medications, the operator places the liquid medication bottle or box below the vial / prescription imaging camera 120. The operator then issues an instruction to photograph the liquid medication bottle or box on the count screen. As shown in Figure 35, when an instruction to photograph the liquid medication bottle or box is received (S161), the control unit 117 of the counter 110 performs the liquid medication bottle / box imaging process (S162), and displays the captured image of the liquid medication bottle or box in the second row of the photo section on the count screen (S163). If the contents of the label on the liquid medication bottle or box cannot be confirmed from the captured image, the liquid medication bottle / box imaging process can be retried (S164). Next, the operator places the prescription for liquid or boxed medication below the vial / prescription imaging camera 120. Then, the operator gives a prescription imaging instruction on the count screen. When a prescription imaging instruction is given (S165), the control unit 117 of the counter 110 performs the prescription imaging process (S166), and displays the captured prescription image in the third row of the photo section on the count screen (S167). If the contents of the prescription cannot be confirmed from the captured image, the prescription imaging process can be retried (S168). The processing after the completion of the series of operations is the same as in step S143 and subsequent steps.

[0089] Manual counting process The drug counting device of the present invention can also perform manual counting processing, which involves simply counting drugs without being linked to prescription data. To perform this manual counting process, the operator touches the manual counting button on the menu screen shown in Figure 37. When the control unit 117 of the counter 110 receives a manual counting instruction (S171), it displays the manual dispensing screen shown in Figure 42 (S172). The operator specifies the required number of counts using the numeric keypad on the screen, takes out the original bottle to be counted, and scans it with the barcode reader 118 of the counter 110, or manually enters the NDC into the screen. When a scan is performed (S174), the control unit 117 of the counter 110 reads the barcode from the original bottle (S175). When NDC manual input is performed (S176), it searches the drug master 121 to identify the drug (S177). Next, the control unit 117 of the counter 110 adjusts the tray size of the counter 110, i.e., the regulated height by the height regulator 41 and the transport width of the second rotating body 35 by the width regulator 52, based on the size of the drug (S178). Next, the control unit 117 of the counter 110 displays a message to put the drug into the tray (S179), and when a counting instruction is received (S180), it performs the counting process (S181) and then terminates the counting process (S182). In manual counting, you can choose to count "all" or "specify count value". If you select "all," the process will finish after counting all the medications placed in the tray. If you select "specify count value," the process will count the entered quantity. In this case, if the quantity is less than the entered quantity, the previously described shortage processing will be performed. This shortage processing requires scanning the NDC code of the original bottle and checking whether it matches the medication being counted.

[0090] Furthermore, although the drug supply device was used as a drug counting device in the above embodiment, it can also be applied to a drug packaging device that stores various drugs in separate cassettes and packages the prescribed drugs according to the prescription.
