Description

Drug dispensing device

The present invention relates to a medicine dispensing device.

Conventionally, as a medicine dispensing device, for example, a cassette containing a plurality of ampoules is arranged in a matrix on the device body, and four prescriptions are collected using four ampule storage chambers provided in the ampule recovery unit. The thing of the structure made to pay out to a chemical | medical agent collection container after collect | recovering is well-known (for example, refer patent document 1).

However, in the conventional medicine dispensing device, when the ampule is collected from the cassette, it is necessary to rotate the ampule storage drum to move each ampule storage chamber to a position where the ampule can be collected, which takes a collection time. Further, the ampules collected in each ampule storage chamber are sequentially paid out to the respective storage chambers divided in the tray, and the payout time cannot be suppressed. Recently, there is an increasing demand for speeding up of drug delivery operations, and even the above-described configuration may not be sufficient. Furthermore, if the internal volume of each ampoule storage chamber is increased, the size of the ampoule is increased, so that the number of ampoules that can be stored is limited, and medicines in other forms (boxed or bagged) cannot be accommodated. .

In addition, as another medicine dispensing device, for example, in order to dispense special medicines such as box packing stacked in the vertical direction, the bottom medicine can be dropped by its own weight by holding the second medicine from the bottom. Are known (see, for example, Patent Documents 2 and 3).

However, in this medicine dispensing apparatus, although the special medicine can be dispensed, it is not configured to dispense into the tray in which the internal space is divided into four (there is no distribution function to each space in the tray). ).

According to the present invention, it is possible to more quickly collect a medicine from a medicine storage unit and to dispense a medicine to the medicine collection unit, and to enlarge a large amount of medicines having different forms at one time. It is an object of the present invention to provide a medicine dispensing device that can distribute and dispense without any problem.

The present invention includes, as means for solving the above-described problems, a medicine dispensing device including a device main body and a plurality of medicine storage containers that are attached to the device main body and are capable of dispensing the stored medicine through a medicine discharge unit. The medicine storage unit and the apparatus main body are movably provided, move to the medicine receiving position, receive the medicine dispensed from the medicine discharge portion of the medicine storage container of the medicine storage unit, and move to the medicine delivery position A medicine receiving unit having a medicine receiving unit that delivers the received medicine, and a medicine storage member having a medicine storage unit that receives and stores the medicine from the medicine receiving unit of the medicine receiving unit moved to the medicine delivery position; A drug recovery unit for recovering the drug discharged from the drug storage unit, wherein at least two drug recovery units are arranged in parallel, and the drug storage member is adjacent to the drug storage unit The first medicine dispensing section is provided with one medicine storage section for the two medicine collection sections, and the medicine storage section can supply the stored medicine to one of the medicine collection sections with the bottom plate as a center. The position can be rotated to a second dispensing position at which the next stored medicine can be supplied to the other side of the medicine collection section.

Further, the present invention provides, as means for solving the above-described problems, a medicine dispensing device, a device main body, and a plurality of medicine storage containers mounted on the device main body and capable of dispensing the stored medicine through a medicine discharging unit. And a medicine receiving unit provided movably on the apparatus main body, moved to a medicine receiving position, and received a medicine dispensed from a medicine discharging portion of a medicine containing container of the medicine containing unit, and a medicine delivery position A medicine receiving unit having a medicine receiving section that delivers the medicine received after moving to the medicine receiving section, and receives a medicine from the medicine receiving section of the medicine receiving unit moved to the medicine delivery position, and is discharged from the medicine receiving section of the medicine storage unit. A drug recovery unit in which at least two drug recovery units are arranged in parallel, and the drug receiving unit is adjacent to the drug recovery unit. A first medicine receiving section is provided for two medicine collecting sections, and the medicine receiving section is capable of supplying the stored medicine to one of the medicine collecting sections with a bottom plate as a center. The medicine stored next can be rotated to the second dispensing position where the medicine can be supplied to the other remaining part of the medicine recovery section.

With these configurations, since one drug storage unit or drug receiving unit is associated with two drug recovery units, the capacity of the drug storage unit or drug receiving unit that can be stored can be increased. Therefore, regardless of the form of the medicine, even a medicine that is easily broken such as an ampoule can be reliably stored and dispensed to each medicine collection section without being damaged. In addition, the dispensing of the medicine to the medicine collecting unit can be handled only by changing the rotation position of the bottom plate. Therefore, quick payout becomes possible. Furthermore, since it can respond by switching the rotation position of a baseplate from one chemical | medical agent storage part or a chemical | medical agent receiving part to two chemical | medical agent collection | recovery parts, respectively, size reduction is attained.

It is preferable that the bottom plate is provided with a guide portion that becomes deeper downward toward the center portion in a horizontal position.

With this configuration, all of the medicines supplied to the medicine reservoir or medicine receiver can be collected in the central portion. Then, when the bottom plate is rotated to be dispensed to the medicine collection unit, it can be always dispensed from the same position regardless of the size of the medicine storage unit or the medicine receiving unit. Therefore, compared with the case where the medicine is dispensed from the end of the medicine storage section or medicine receiving section, the drop size can be greatly suppressed, and the medicine dispensing state to the medicine collection section can be stabilized. This is particularly effective for fragile drugs such as ampoules.

When the bottom plate is rotated to the first rotation position or the second rotation position, a part of the bottom plate can enter the drug recovery unit of the drug recovery unit, and the upper side is centered on the shaft portion. It is preferable to have a configuration including a rotating part that can only rotate.

With this configuration, the medicine dispensed from the medicine storage part or medicine receiving part can be smoothly transferred to the medicine recovery part without spilling to the side and without applying an impact force more than necessary by suppressing the drop size. Can be moved. In addition, even if the bottom plate interferes with the medicine collected by the medicine collecting unit, the rotating part is rotated upward to sufficiently reduce the load acting on the medicine and the bottom plate, resulting in damage. Can be prevented.

The guide guides provided on both sides of the medicine storage part or the medicine receiving part have inclined surfaces that project inward as it goes upward, and the pivot center of the bottom plate of the medicine storage part It is preferable that the position does not interfere with both side surfaces.

With this configuration, when the bottom plate is positioned at the horizontal position, both sides are covered with the guide guides in plan view. For this reason, even if the medicine to be supplied to the medicine storage part or medicine receiving part is packed in a bag, it does not enter the gap formed between the bottom plate and the guide guide. Even if a part of the drug is caught in the gap, if the bottom plate rotates, the drug will be discharged to the drug recovery part side or returned to the inside by the side part of the bottom plate, and clogging will occur do not do. Therefore, various forms of drugs can be stored and dispensed to the drug recovery unit.

Both side parts of the medicine storage part or medicine receiving part are provided with convex parts at predetermined intervals along the both side parts, and the bottom plate of the medicine storage part or medicine receiving part is provided with the convex parts at predetermined intervals along both side parts. It is preferable to provide a notch for avoiding interference with the.

With this configuration, even if the medicine to be supplied to the medicine storage unit or the medicine receiving unit is packed in a bag or the like, the range that can be invaded due to the presence of the convex portion can be cut into pieces. That is, since the convex portions are positioned at a predetermined interval, a gap formed between both side portions of the medicine storage portion or medicine receiving portion and both side edges of the bottom plate has a zigzag shape. For this reason, the edge part of the bag in which the medicine is accommodated cannot enter. Therefore, various forms of medicines can be stored and dispensed to the medicine collection unit.

It is preferable that the bottom plate is provided with a guide portion that can be positioned at a guide position that extends into the medicine recovery portion when the bottom plate rotates toward each payout position at both ends.

With this configuration, the medicine can be guided by the guide part to the vicinity of the bottom of the medicine container. Therefore, it is possible to sufficiently suppress the impact force that is received when the medicine is dispensed to the medicine container, thereby preventing damage.

Both end sides of the bottom plate are constituted by partition plates, and include an operation unit that allows the guide portion to move to the guide position and a retreat position that avoids interference with the partition plate when the bottom plate rotates. preferable. Here, the action part means a mechanism for positioning the guide part at an appropriate position (at least a guide position where the guide part extends into the medicine recovery part).

With this configuration, the guide unit can be automatically moved to an appropriate position by the operation unit in accordance with the rotation operation of the bottom plate.

Each guide part is rotatably connected to both ends of the bottom plate, and the operation part is provided in the guide part formed on the partition plate and the guide part, and when the bottom plate rotates, It is preferable that the guide portion is configured to be guided by the guide portion.

With this configuration, the guide unit can be automatically moved to an appropriate position in spite of the simple configuration in which the guided unit is simply guided by the guide unit.

When the medicine placed on the bottom plate moves toward the medicine recovery section side by rotating the bottom plate toward one of the dispensing positions, the operation section causes the guide section to move to the guide position. It is preferable to rotate to the side.

With this configuration, the placed medicine can be smoothly moved in the dispensing direction.

The bottom plate is provided with a stopper for restricting the rotation range of the guide portion so that the guided portion does not rotate beyond the rotation position when the guided portion is no longer guided by the guide portion due to the rotation of the bottom plate. It is preferable to provide.

With this configuration, the guided portion can be maintained at a position where it can be guided by the guide portion, and the bottom plate can be smoothly returned from the payout position to the original position.

It is preferable that a control unit that temporarily stops the rotation of the bottom plate is provided in the middle of the rotation of the bottom plate and immediately before the medicine is dispensed to the medicine collection unit.

With this configuration, the movement of the medicine accompanying the rotation of the bottom plate can be temporarily stopped, so that the delivery speed of the medicine to the medicine collection section thereafter is reduced, and the impact force received when dispensing to the medicine collection section is sufficient. It becomes possible to relax.

The stop position of the bottom plate is preferably a position where the guide of the guided portion by the guide portion is released and the medicine is prevented from dropping by the partition plate.

With this configuration, the medicine dispensing position from the bottom plate can be made sufficiently close to the medicine collection unit, so that the impact force received by the medicine to be dispensed can be further reduced.

According to the present invention, since the medicine can be dispensed from one medicine storage part or medicine receiving part to two medicine recovery parts, the quantity of medicines stored in the medicine storage part or medicine receiving part Even if there are variations in the shape, the drug can be reliably stored. And when paying out the medicine, it is possible to pay out the medicine to any of the medicine collecting sections only by changing the rotation position of the bottom plate. For this reason, it becomes possible to perform a quick and stable drug delivery.

Further, each guide plate 14a, 14b is configured to be rotated by a motor (not shown) to prevent the drug from remaining. Further, the bottom surfaces of the storage containers 12 and 13 can be opened, and after the medicine receiving unit 3 moves to the medicine collection unit 4, it is opened and the medicine supplied from the cassette 7 is discharged.

(1-3. Drug Recovery Unit 4) As shown in FIG. 1, the drug recovery unit 4 includes a drug storage member 15 and a drug recovery container 17 that is disposed on the lower side thereof and is transported by the transport member 16. .

As shown in FIG. 3, the drug storage member 15 has a rectangular shape in plan view, and the frame 18 constituting both sides is divided into two by four partition plates 20 to store drug storage parts (first drug storage part 19 a and Each of the second medicine storage portions 19b) is formed. On the back side of the medicine storage member 15, as shown in FIG. 6A, pulleys 110 and 111 are arranged above and below, respectively. The lower pulley 111 is fixed to the rotating shaft of the motor 112 attached to the bottom surface of the apparatus main body 1, and one end of the belt 113 is connected to the lower pulley 111. The belt 113 is stretched over the pulley 110 on the upper side, and the other end is fixed to the back surface of the medicine storage member 15. In addition, a protruding piece 114 serving as a detected portion is provided on the back surface of the medicine storage member 15. The protruding piece 114 is detected by a sensor 115 provided on the back side at the raised position of the medicine storage member 15. In addition, a projecting piece 116 serving as a detected portion is also provided on the end surface of the pulley 111 on the lower side. The protruding piece 116 rotates together with the pulley 111 and is detected by the sensor 117 at the lowered position of the medicine storage member 15. Thereby, it is possible to drive the motor 113 to position the medicine storage member 15 at the raised position and the lowered position, respectively.

Each medicine storage section 19a, 19b is located below each container 12, 13 when the medicine receiving section 9 of the medicine receiving unit 3 moves to the medicine delivery position (FIGS. 9D, 9E). reference). As shown in FIG. 3, the bottom surfaces of the medicine storage portions 19 a and 19 b are respectively configured by bottom plates 22 that are provided so as to be rotatable about a support shaft 21.

As shown in FIG. 3, a guide guide 23 made of a synthetic resin material is formed on the inner surface of the upper part of the partition plate 20. The guide guide 23 includes an inclined surface 23a that gradually inclines upward toward the inside, and maintains a gap with the bottom plate 22 at a certain size, as will be described later. Therefore, the gap between the bottom plate 22 and the partition plate 20 in the initial horizontal position is covered with the guide guide 23 that protrudes inward in a plan view. The lower edge portion of each partition plate 20 is constituted by a guide piece 24. As for the guide piece 24, the front-end | tip part inclines inside each chemical | medical agent storage part 19a, 19b. The guide piece 24 enters the medicine collection container 17 when the medicine storage member 15 is in the lowered position, and the medicine spills sideways when the medicine is discharged by rotating the bottom plate 22. To prevent.

The bottom plate 22 is formed in a substantially arc-shaped cross section (may be arc-shaped) that is most depressed at the center. The part formed in this substantially circular arc shape plays a role as a guide part, and collects medicines respectively supplied from the storage containers 12 and 13 to the central part. In other words, the position of the medicine is always adjusted to the central portion as long as the bottom plate 22 is located at the initial horizontal position, regardless of the difference in the dispensing position of the medicine from the storage containers 12 and 13. Therefore, as described later, when the bottom plate 22 is rotated to the respective dispensing positions and dispensed to the respective drug collection units 31a to 31d, the drug can always be moved from a certain position (center portion), It is possible to stabilize the dispensing state by making the dispensing conditions of the medicines 31a to 31d the same.

Both side portions of the bottom plate 22 are constituted by turning portions 25 that can turn only upward about a shaft portion 25a. As a result, even if the bottom plate 22 rotates and enters the medicine recovery container 17 and interferes with the medicine or the like stored therein, the rotating portion 25 rotates to damage the medicine or the bottom plate. It is possible to prevent an unreasonable load on 22.

An elastic sheet 26 is attached to the upper surface of the bottom plate 22 by screwing or sticking with an adhesive. The elastic sheet 26 alleviates the impact on the medicine supplied from the medicine receiving container and prevents the medicine from being damaged.

The support shaft 21 of the bottom plate 22 is disposed at a predetermined position (here, in the vicinity of the deepest position of the bottom plate 22) on the lower side with respect to the horizontal plane connecting both side edges at the initial horizontal position. As a result, when the bottom plate 22 is rotated from the initial horizontal position, both edge portions of the bottom plate 22 draw an arcuate trajectory A that is directed to the upper inside of the medicine reservoirs 19a and 19b. The guide guide 23 of the partition plate 20 is formed of an inclined surface that gradually inclines upward toward the inside, so that it does not interfere with the trajectory A of both end edges of the bottom plate 22 (that is, the guide guide 23 is Designed to constitute a tangent line extending from the starting point of movement of the trajectory A). Therefore, if the bottom plate 22 is in the initial horizontal position, the gap portion formed between the both edge portions of the bottom plate 22 and the guide guides 23 of the partition plate 20 is the medicine storage portion 19a of the guide guide 23, It is covered by a portion that protrudes to the inside of 19b and is hidden in plan view. For this reason, even if the medicine supplied from the medicine receiving unit 3 to the medicine reservoirs 19a and 19b is stored in a bag, for example, the edge thereof may enter the gap and cause clogging. Absent. Even if the medicine is caught in the gap, if the bottom plate 22 rotates, the side edge portion moves inward along the inclined surface of the guide guide 23, so that the medicine is smoothly moved inward. Can be moved. Therefore, the clogged state of the medicine can be easily eliminated.

As shown in FIG. 6A, the bottom plate 22 is rotated via the drive gear 121 and the driven gear 122 by the forward / reverse rotation drive of the motor 120, and the support shaft 21 is moved from the initial horizontal position shown in FIG. As a center, the first payout position rotated about 90 degrees counterclockwise and the second payout position rotated about 90 degrees clockwise rotate, respectively.

As shown in FIG. 6, the support shaft 21 is attached with three discs (first to third discs 27a to 27c) as detected portions. Notches 28a to 28c are formed in the disks 27a to 27c with the pitch shifted in the circumferential direction. The notches 28a to 28c of the disks 27a to 27c are detected by sensors (first to third sensors 29a to 29c), respectively. When the bottom plate 22 is positioned at the initial horizontal position, the cutout portion 28a of the first disc 27a is detected by the first sensor 29a. When the bottom plate 22 is rotated counterclockwise to the first payout position, the notch 28b of the second disc 27b is detected by the second sensor 29b. During this time, the first sensor 29a and the third sensor 29c remain blocked by the first disc 27a and the third disc 27c. When the bottom plate 22 is rotated clockwise to reach the second payout position, the cutout portion 28c of the third disk 27c is detected by the third sensor 29c. During this time, the first sensor 29a and the second sensor 29b remain blocked by the first disk 27a and the second disk 27b.

As shown in FIG. 2, the transport member 16 includes a transport belt 30 driven by a motor (not shown). The transport member 16 is loaded into the apparatus main body 1, temporarily stopped at the collection position, and then transported to the outside. To do.

The medicine collection container 17 is divided into four parts by a sorting plate to form first to fourth medicine collection parts 31a to 31d, respectively. This is in accordance with the maximum number of prescriptions (morning, noon, evening, evening) per patient. Each of the drug collection units 31a to 31d is formed so that two sizes correspond to one drug storage unit 19a or 19b of the drug storage member 15. That is, in the state where the medicine recovery container 17 is transported by the transport member 16 and is positioned below the medicine storage member 15, the first medicine storage section above the first and second medicine recovery sections 31a and 31b of the medicine collection container 17 is used. 19a is located, and the second medicine reservoir 19b is located above the third and fourth medicine collection parts 31c and 31d.

(1-4. Control Unit 5) Based on prescription data input from a host computer (not shown) or the like, the control unit 5 refers to the coordinate data of the dispensing outlet 8 of the cassette 7 stored in the memory, and the like. Run the program. That is, the medicine receiving unit 3 is moved by driving and controlling various motors. Then, the corresponding medicine is dispensed and collected from the cassette 7 of the medicine storage unit 2, and the medicine is dispensed to the medicine collection container 17 through the medicine storage member 15. Thereafter, the medicine collection container 17 is moved to carry out the dispensed medicine.

(2. Operation) Next, the operation (medicine supply process and drug delivery process) of the medicine dispensing apparatus having the above-described configuration will be described with reference to the flowcharts shown in FIGS.

(2-1. Drug Supply Processing) As shown in FIG. 7, first, based on the prescription data, it is determined whether or not there is a drug dispensing instruction (step S1). If there is a dispensing instruction, it is determined to which container 12 or 13 of the medicine receiving section 9 the medicine is to be supplied (step S2). Here, the first supply container 12 is determined as the first supply container, and then changed to the second storage container 13.

The medicine receiving unit 9 is moved from the state shown in FIG. Then, as shown in FIG. 9B, the medicine to be dispensed to the first medicine collection unit 31a (or the second medicine collection unit 31b) of the medicine collection container 17 is supplied to the first container 12 (step S3). ). When the medicine is supplied to the first medicine collection unit 31a, the medicine receiving unit 3 is moved, and the guide plate 14a of the first container 12 is supplied to the first medicine collection unit 31a (or the second medicine collection unit 31b). It positions in the discharge outlet 8 of the cassette 7 in which the chemical | medical agent was accommodated. Then, a predetermined quantity of medicine is supplied according to the prescription data.

When the supply of the medicine to the first container 12 is completed, the medicine to be dispensed to the third medicine collection unit 31c (or the fourth medicine collection unit 31d) of the medicine collection container 17 as shown in FIG. Supply (step S4). That is, the medicine receiving unit 3 is moved, and the guide plate 14b of the second container 13 is moved to the outlet of the cassette 7 in which the medicine to be dispensed to the third medicine collecting unit 31c (or the fourth medicine collecting unit 31d) is stored. Position it. In the same manner as described above, a predetermined amount of medicine is supplied according to the prescription data. At this time, the guide plate 14b is rotated by a motor (not shown) so that the medicine is not left on the guide plate 14b and is supplied to the second storage container 13 entirely. When the supply of the medicine to the second container 13 is completed, the medicine receiving unit 3 is moved to the medicine collection unit 4 as shown in FIG. 9 (d) (step S5).

In the medicine collection unit 4, the medicine receiving unit 3 is positioned so that the first medicine storage portion 19 a is located below the first container 12 and the second medicine reservoir 19 b is located below the second container 13. . Then, the medicine receiving unit 3 is lowered, and as shown in FIG. 9 (e), the bottom surfaces of the storage containers 12 and 13 are opened, and the dispensed medicine is stored in the medicine storage portions 19 a and 19 b of the medicine storage member 15. (Step S6). In this case, the medicine receiving unit 3 is lowered and sufficiently close to the medicine collection unit 4, so that the medicine does not spill sideways. Moreover, since the fall distance can be shortened, it is possible to suppress the impact force received by the medicine. Furthermore, in each chemical | medical agent storage part 19a, 19b, the bottom face is comprised with the baseplate 22 with a cross-sectional arc shape. For this reason, the stored medicine is collected in the central portion.

If a medicine is stored in each medicine storage part 19a, 19b, as shown in FIG. 9 (f), the medicine receiving unit 3 is moved (step S7), and the next medicine is collected. That is, the medicine receiving unit 3 is moved, and the discharge port 8 of the cassette 7 in which the medicine for dispensing the guide plate 14a of the first container 12 to the second medicine collecting unit 31b (or the first medicine collecting unit 31a) is stored. Position to. Then, a predetermined quantity of medicine is supplied according to the prescription data (step S8). When the supply of the medicine to the first container 12 is completed, the medicine receiving unit 3 is moved, and the guide plate 14b of the second container 13 is moved to the fourth medicine collection part 31d (or the third medicine collection part 31c). It positions in the discharge port of the cassette 7 in which the medicine to be dispensed is stored. In the same manner as described above, a predetermined quantity of medicine is supplied according to the prescription data (step S9). When the supply of the medicine to the second container 13 is completed, the medicine receiving unit 3 is moved to the medicine collecting unit 4 (step S10). Subsequently, in the same manner as described above, the bottom surfaces of the storage containers 12 and 13 are opened, and the dispensed medicine is supplied to the medicine storage portions 19a and 19b of the medicine storage member 15 (step S11).

(2-2. Drug Dispensing Process) The drug storage member 15 waits until the drug collection container 17 is positioned at the discharge position below it as shown in FIG. When the medicine collection container 17 is positioned at the discharge position (step S21), the medicine storage member 15 is lowered (step S22) as shown in FIGS. Approach the medicine collection container 17. Further, it is determined which of the medicine collection units 31a to 31d the stored medicine is to be dispensed (step S23).

As shown in FIG. 9 (h), the medicine is dispensed by rotating each bottom plate 22 by approximately 90 degrees (step S24).

When the medicine stored in the first medicine storage section 19a is dispensed to the first medicine collection section 31a, the bottom plate 22 is moved from the state shown in FIG. 4 (a) as shown in FIGS. 4 (b) and 4 (c). 6C, the second sensor 29b detects the cutout portion 28b of the second disk 27b and stops the rotation. Accordingly, as shown in FIG. 5A, the bottom plate 22 stops when it is rotated about 90 degrees from the initial horizontal position, and the stored medicine is dispensed to the first medicine collection section 31a. Since the bottom plate 22 is formed in a substantially arc shape in cross section as described above, the stored medicine is gathered in the central portion. Then, the drug smoothly moves to the first drug recovery unit 31a as the bottom plate 22 rotates. In this case, even if a part of the medicine enters the gap between the side edge of the bottom plate 22 and the guide guide 23 (packing), the rotation trajectory A of the side edge of the bottom plate 22 is the guide guide. It changes so that the space | interval with 23 may be expanded gradually. That is, as shown in FIG. 4A to FIG. 4B, the right side edge of the bottom plate 22 moves obliquely upward to the left, and the guide guide 23 is moved with respect to the inclined surface of the guide guide 23. Since the gap with the inclined surface is gradually widened, the drug is not overloaded and damaged. Moreover, since the inclined surface of the guide guide 23 is located on the upper side with respect to the medicine, the medicine moves inward while being guided by this inclined surface as the bottom plate 22 rotates. Therefore, the medicine is not clogged, and the medicine moves smoothly toward the center of the bottom plate 22. Also, as shown in FIG. 12 (d), the one end edge side of the bottom plate 22 has entered the first medicine recovery part 31a, so that the medicine hardly falls freely, and it falls freely. However, since the distance is very small, it is not damaged by impact. In the unlikely event that the drug tends to jump out of the first drug collection unit 31a, the guide piece 24 is located there, so that it does not flow out to the side.

FIG. 12 shows a comparative example of the drop size of the medicine. FIGS. 12A and 12B show a case where the bottom plate 22 has a flat plate shape. FIG. 12C shows a case where the bottom plate 22 has an arc shape. FIG. 12D shows a case where the bottom plate 22 has an arc shape and a part of the bottom plate 22 enters the first medicine recovery unit 31a. FIG. 12 (e) compares the drop dimensions in FIGS. 12 (a) to 12 (d). As is clear from FIG. 12, the method according to the above embodiment, that is, the method according to FIG. It is possible to suppress the drop size of the drug most.

On the other hand, when the medicine stored in the first medicine storage section 19a is dispensed to the second medicine collection section 31b, the bottom plate 22 is rotated clockwise from the state shown in FIG. As shown, the third sensor 29c may be stopped when the cutout portion 28c of the third disk 27c is detected. Thereby, a medicine is paid out to the 2nd medicine recovery part 31b. Since the medicine dispensing operation in this case is the same as the discharging operation to the first medicine collection unit 31a described above, the description thereof is omitted.

Moreover, the medicine stored in the second medicine storage section 19b is paid out to the third medicine collection section 31c or the fourth medicine collection section 31d. Since this dispensing operation is the same as that of the first medicine reservoir 19a, the description thereof is omitted. However, if the first drug reservoir 19a and the bottom plate 22 of the second drug reservoir 19b are linked (by a belt, a chain, etc.), only one power source is required. In this case, if the drug stored in the first drug storage unit 19a is dispensed to the first drug collection unit 31a, the drug stored in the second drug storage unit 19b needs to be dispensed to the third drug collection unit 31c. If the drug stored in the first drug storage unit 19a is dispensed to the second drug collection unit 31b, the drug stored in the second drug storage unit 19b needs to be dispensed to the fourth drug collection unit 31d.

As shown in FIGS. 9 (i) and 9 (j), the medicine receiving unit 3 moved to collect the next medicine is moved to the medicine collecting unit 4 as described above, and each medicine storage section 19a is moved. 19b to store the drug. In each medicine storage part 19a, 19b, the bottom plate 22 is rotated in a direction opposite to the above-mentioned direction (for example, if it is rotated counterclockwise, it is clockwise). As a result, the medicines are dispensed to the remaining medicine collection units 31a and 31c (or 31b and 31d), respectively.

In this way, the first container 12 and the second drug recovery unit 31a and the second drug recovery unit 31b, or the third drug recovery unit 31c and the fourth drug recovery unit 31d, respectively, Since it is only necessary to move the container 13 up and down and to the left and right in a state of being adjacent to each other, the configuration can be simplified and manufactured at a low cost. In addition, since the medicine can be temporarily stored in the medicine storage member 15 disposed in the vicinity of the medicine collection container 17 and the stored medicine can be discharged to the medicine collection container 17 at the same time, a quick dispensing operation can be performed. . Furthermore, since the medicine is dispensed from the first medicine storage section 19a to each medicine collection section 31a or 31b and from the second medicine storage section 19b to each medicine collection section 31c or 31d, the storage area is widened. be able to. For this reason, even drugs having different forms such as quantity, boxed medicine, or bagging medicine can be dispensed smoothly. In particular, since the bottom plate 22 is formed in a substantially arc shape, the bottom plate 22 can be collected in the central portion regardless of the quantity or form of the medicine. For this reason, the dispensing conditions to each of the drug recovery units 31a to 31d can always be constant, and a stable dispensing operation can be realized. In addition, since both side portions of the bottom plate 22 are intruded into the drug recovery units 31a to 31d, it is difficult to apply an impact force to the drug when it is dispensed, and damage can be prevented. In addition, since both side portions of the bottom plate 22 are configured by the rotating portion 25 and can be rotated only upward, even if a drug or the like comes into contact with the rotating portion 25, the medicine or the bottom plate 22 or An unreasonable load does not act on the drive source, and damage can be prevented.

In addition, when paying out a plurality of types of medicines to the first container 12 and the second container 13, the order of dispensing can be freely set. For example, when one A drug is dispensed into the first storage container 12 and one A drug and one B drug are dispensed into the second storage container 13, after the A drug is dispensed into the first storage container 12, In the two container 13, one B medicine may be paid out first, not the A medicine. Further, when one A medicine and one B medicine are dispensed to the first container 12 and one A medicine is dispensed to the second container 13, after one A medicine is dispensed to the first container 12 Before dispensing one drug A to the second container 13, one drug B may be dispensed first to the first container 12, or second before the first container 12. You may make it pay out one A chemical | medical agent with the container 13.

(3. Other Embodiments) The present invention is not limited to the above-described embodiments, and various modifications and the like are possible within the scope of the technical matters described in the claims.

In the said embodiment, although the bottom plate 22 of each storage part of a tablet storage member was formed in cross-sectional arc shape, it is good also as a cross-sectional substantially V shape, for example not only in this. The point is that the bottom plate 22 may have any shape that allows the medicine supplied to the bottom plate 22 at the horizontal reference position to be collected toward the center by its own weight.

In the above embodiment, the rotational position of the bottom plate 22 is detected by the three disks 27a to 27c and the three sensors 29a to 29c provided on the support shaft 21, but as shown in FIG. It is also possible to detect by two disks 32a and 32b and two sensors 33a and 33b. That is, the disks 32a and 32b are both formed in a semicircular shape, and are fixed while being displaced in the circumferential direction around the support shaft 21. When the bottom plate 22 is positioned at the horizontal reference position, the sensors 33a and 33b both detect the disks 32a and 32b. When the bottom plate 22 is rotated to the first payout position, the sensors 33a and 33b both detect the disks 32a and 32b. It is set so that only the sensor 33b does not detect the disc 32b when it is no longer detected and rotated to the second payout position. Thereby, the number of parts can be reduced, and the rotation direction of the bottom plate 22 can be detected at low cost.

In the above embodiment, the gap formed between the both side portions of the bottom plate 22 at the horizontal reference position and the partition plate 20 is covered with the guide guide 23 in a plan view. It is also possible to configure as described above.

That is, as shown in FIG. 11, the arcuate surface 34 is formed on the partition plate 20 along the rotation trajectory A on both sides of the bottom plate 22. A plurality of convex portions 35 are formed at predetermined intervals along both side portions of the bottom plate 22 on the circular arc surface 34 (or the upper edge portion of the circular arc surface 34). In addition, the convex part 35 can set the thickness to the direction along both sides part freely. On the other hand, notches 36 for avoiding interference with the projections 35 are formed on both sides of the bottom plate 22. As a result, the gap is not continuously formed in the direction along both side portions of the bottom plate 22. That is, there is no continuous gap into which a part of the medicine (for example, the edge of the packed medicine) can enter, and the same function as the guide guide 23 is exhibited. For this reason, when the bottom plate 22 rotates from the horizontal position, even if the rotation trajectory A of the side edge portion gradually approaches the arc surface 34, there is no possibility that a part of the medicine is clogged. .

In the above embodiment, the bottom plate 22 has a substantially arc-shaped cross section, and rotates about the support shaft 21 arranged at the center. However, for example, the support shaft 21 may be one end side of the bottom plate 22. Is possible. In this case, the drug collection container 17 may be moved to shift the position of the drug collection unit that dispenses the drug.

Moreover, in the said embodiment, although the chemical | medical agent supplied from the chemical | medical agent receiving unit 3 was once stored in the chemical | medical agent storage member 15, this chemical | medical agent storage member 15 is not necessarily required. For example, the medicine reservoir member 15 is eliminated, and the bottom surface of each medicine receiver 9 of the medicine receiver unit 3 (in this case, each medicine receiver 9 functions as a medicine reservoir) is used as the bottom plate 22 of the medicine reservoir member 15. It is good also as a structure similar to. According to this configuration, the next medicine cannot be collected unless the medicine is dispensed from the medicine receiving unit 3 to the medicine collection container 17, but the medicine storage member 15 is not required, so that a compact configuration can be achieved. It becomes.

Moreover, in the said embodiment, although the chemical | medical agent storage member 51 of the chemical | medical agent collection unit 4 was set as the structure shown in FIG. 3, it is good also as a structure shown in FIGS.

That is, the medicine storage member 51 shown in FIGS. 13 and 14 has a rectangular shape in plan view, like the medicine storage member 15 shown in FIG. In addition, the frame plate 52 that constitutes both sides is divided into two by four partition plates 53 to form a medicine reservoir 54 (a first medicine reservoir 54a and a second medicine reservoir 54b).

Each partition plate 53 includes an inclined portion 55 that protrudes obliquely downward from the lower end of the frame plate 52. Further, as shown in FIG. 16, each partition plate 53 is formed with guide portions 56 extending at substantially right angles at both side edges. The guide portion 56 is located on the inner surface of the frame plate 52 and extends downward from the upper end in parallel with the inner surface of the partition plate 53, and a first inclined portion 56b extending obliquely downward from the vertical portion 56a. And a second inclined portion 56c extending obliquely downward from the first inclined portion 56b with a larger inclination angle. And the protrusion 64 of the rotation part 63 mentioned later contacts the guide part 56 so that it may slide (or roll). Here, the operating portion according to the present invention is constituted by the guide portion 56 and the protrusion 64.

The bottom surfaces of the

drug storage portions

54a and 54b are respectively constituted by bottom plates 57 provided so as to be rotatable about a support shaft 57a. The position of the support shaft 57a is substantially the center position in the vertical and horizontal directions of the frame plate 52. As in FIG. 3, the bottom plate 57 is rotated by driving the motor 58, and the rotation position is the same as in FIG. 6 except that the

semicircular plates

57b and 57c provided on the support shaft 57a are replaced by the optical sensors 59a, It can be specified by detecting each at 59b. That is, by driving and controlling the motor 58 based on detection signals from the

optical sensors

59a and 59b, the bottom plate 57 is moved from the initial horizontal position (the first bottom surface portion 60 of the bottom plate 57 is positioned on the horizontal plane). The first payout position rotated about 90 degrees in the rotation direction and the second payout position rotated about 90 degrees in the counterclockwise direction can be positioned respectively.

As shown in FIGS. 13 and 14, in the bottom plate 57, the most depressed portion in the center is the first bottom surface portion 60, and the portions extending obliquely from both ends of the first bottom surface portion 60 are the second bottom surface portion 61. It is. And as a whole, the longitudinal section has a substantially arc shape (may be an arc shape). The part formed in the substantially arc shape functions as a guide part, and collects the medicine M supplied from each of the storage containers 12 and 13 to the central part. That is, the position of the medicine M is always adjusted to the central portion as long as the bottom plate 57 is located at the initial horizontal position, regardless of the difference in the dispensing position of the medicine M from the respective containers 12 and 13.

As shown in FIG. 15, stopper pieces 62 further protrude from the tip of each second bottom surface portion 61. Moreover, the rotation part 63 is attached to the front-end | tip part of each 2nd bottom face part 61 so that rotation is possible centering on the spindle 63a by hinge coupling.

Guide walls

60 a, 61 a, 63 b stand from both side edges of the first bottom surface portion 60, the second bottom surface portion 61, and the rotating portion 63, and have a substantially U-shaped cross section.

Each rotating portion 63 is prevented from rotating downward beyond the second bottom surface portion 61 by the stopper piece 62. In a state in which the rotating unit 63 is in contact with the stopper piece 62, the angle formed by the rotating unit 63 with respect to the horizontal plane is as shown in FIG. The drug M may be set to a value that falls sideways without standing in the longitudinal direction in relation to the position of the center of gravity.

Protrusions 64 are formed on the outer surfaces on both sides of each rotating portion 63 (only one side may be provided). Here, each protrusion 64 is comprised with the bearing which has a rotatable outer ring | wheel, and slides the guide part 56 of the said frame board 52 (or rolling). Note that the position of the protrusion 64 is higher than the plane on which the second bottom surface portion 61 is located with respect to the support shaft 63 a that is the rotation center of the rotating portion 63.

As shown in FIG. 13, a sheet 65 is attached to the upper surfaces of the bottom plate 57 and the rotating portion 63. The sheet 65 is made of elastic rubber or the like, and alleviates the impact force received by the supplied medicine M (particularly, ampoules).

According to the rotating part 63, when the bottom plate 57 rotates from the initial horizontal position shown in FIG. 17 (a), the rotating part 63 (in FIG. 17 (a)) moves upward along with this rotating operation. (Position on the right side) loses support by the inner surface of the partition plate 53 as shown in FIG. For this reason, the rotation part 63 rotates until the bottom face contacts the stopper piece 62 by its own weight. However, since the sheet 65 is adhered to the upper surface of the rotating portion 63, the bottom plate 57 rotates to the first payout position shown in FIG. 18A (the same applies to the second payout position) as will be described later. Even if it does, the rotation part 63 does not rotate. That is, rattling of the rotating part 63 is prevented.

On the other hand, in the rotating portion 63 that moves downward as the bottom plate 57 rotates, the position of the guide portion 56 where the protrusion 64 slides (or rolls) gradually from the support shaft 63 a of the rotating portion 63. In order to move away, as shown in FIG. 17B, the angle formed between the second bottom surface portion 61 and the second bottom surface portion 61 is gradually increased. Then, as shown in FIG. 17C, when the bottom plate 57 rotates approximately 60 degrees from the initial position, the protrusion 64 of the rotating portion 63 loses support of the guide portion 56. At this time, the rotating portion 63 rotates to a position where it comes into contact with the stopper piece 62, and is positioned on substantially the same plane as the second bottom surface portion 61.

The medicine storage member 51 can be moved in the vertical and horizontal directions by the action of a motor, a pulley, and a belt (not shown) as in FIG.

Here, the operation of the medicine storage member 51 having the above-described configuration will be described. That is, in the same manner as in steps S1 to S24 in the flowcharts shown in FIGS. 7 and 8, it is supplied from the cassette 7 of the medicine storage unit 2 to any of the storage containers 12 and 13 of the medicine receiver 9 based on the prescription data. The medicine M is supplied to each medicine storage section 54 of the medicine storage member 51. Then, the medicine M supplied to each medicine storage section 54 is paid out to any one of the medicine collection sections 31a to 31d of the medicine collection container 17 positioned at the discharge position. In the following description, only the case of dispensing to the medicine collection unit 31a will be mentioned.

In the medicine reservoir 54, the bottom plate 57 is rotated to the first payout position. At this time, the rotating portion 63 rotates so that the angle formed between the protrusion 64 and the second bottom surface portion 61 gradually increases when the projection 64 slides (or rolls) the guide portion 56 of the partition plate 53. To do. Then, as shown in FIG. 17 (c), when the bottom plate 57 rotates about 60 degrees from the initial horizontal position, the rotating portion 63 rotates to a position where it substantially contacts the stopper piece 62.

As the bottom plate 57 rotates, the medicine M stored in the medicine storage portion 54 slides on the upper surface of the bottom plate 57 by its own weight and gradually moves toward the turning portion. Then, it further moves toward the distal end side of the rotation unit 63 along with the rotation operation of the rotation unit 63. Then, once the bottom plate 57 exceeds the position shown in FIG. 17C and reaches the intermediate position, the rotation of the bottom plate 57 is temporarily stopped (for example, less than 1 second. Here, 0.2 to 0.00). 3 seconds.) The intermediate position is a position where the protrusion 64 loses the support by the guide portion 56, but is prevented from dropping the drug M in contact with the partition plate 53, and the movement of the drug M is stopped.

After that, when the rotation of the bottom plate 57 is resumed and the first dispensing position shown in FIG. 18A is reached, the medicine M loses the guide of the partition plate 53 and is dispensed to the medicine collection unit 31a. In this case, since the rotation part 63 rotates and extends to the inside of the medicine recovery part 31a, the medicine M smoothly moves into the medicine recovery part 31a. If the medicine M has a normal size, the medicine M slides down obliquely as it is, so that the medicine M always falls on its side after colliding with the bottom surface of the medicine collection unit 31a. In this case, as described above, since the movement of the drug is temporarily stopped at the intermediate position, the moving speed of the drug M sliding down can be reduced. For this reason, there is no fear that the medicine M jumps out of the medicine collection unit 31a with excessive momentum. Further, when the medicine M collides with the bottom surface of the recovery part 31a, it does not receive a large impact force and therefore is not damaged.

In the case of a large-sized drug M that protrudes upward when stored in the drug recovery unit 31a in the longitudinal direction, the rotation unit 63 slides down, and a part of the drug M is stored on the bottom surface of the drug recovery unit 31a. Abut. Therefore, the medicine M slides down the rotating part 63 and does not fall freely. For this reason, when the medicine M collides with the bottom surface of the medicine recovery unit 31a, the movement of the medicine is temporarily stopped at the intermediate position and the moving speed of the sliding medicine M is reduced, as described above. It is not subject to impact forces and therefore will not be damaged and will not stand up. Then, if the bottom plate 57 is rotated to the first payout position (at this time, it may be temporarily stopped so that a part of the large-sized medicine M reliably contacts the bottom surface of the medicine collection unit 31a). As shown in FIG. 18B, the medicine storage member 51 is moved upward. Thereby, while the medicine M maintains a state in which a part thereof is in contact with the bottom surface of the medicine recovery unit 31a, the support area by the rotating part 63 on the opposite side gradually decreases. And as shown in FIG.18 (c), when the support by the rotation part 63 is lose | eliminated completely, the chemical | medical agent M is mounted in the state lying down on the bottom face of the chemical | medical agent collection | recovery part 31a.

If the medicine M is, for example, a box-shaped rectangular parallelepiped shape, when the medicine M is dispensed to the medicine collection unit 31a by free fall, the medicine M may stand up in the longitudinal direction. In particular, when the medicine M is dispensed from the cassette 7, since the longitudinal direction of the medicine is the left-right direction shown in FIG. 15, the state tends to stand up in the longitudinal direction. However, as described above, by providing the rotation unit 63, the medicine M can be paid out to the medicine collection unit 31a in an inclined state, so that the medicine M does not stand up in the longitudinal direction.

By the way, a part (for example, a base part) or the whole of the rotating part 63 can be constituted by an elastic piece. That is, when the protrusion 64 loses support by the guide portion 56, the elastic piece is elastically deformed by the weight of the medicine M, and the rotating portion 63 or the elastic piece may be positioned in the medicine collection portion 31a. Further, when the bottom plate 57 is rotated and the medicine M is released from the contact state with the inner surface of the partition plate 53, the elastic piece is elastically deformed by the weight of the medicine M, and the rotating portion 63 or the elastic piece is the medicine. You may make it locate in the collection | recovery part 31a. Thereby, the same effect as that of the rotating part 63 is obtained.

Further, it is possible to use an urging member such as a permanent magnet or a spring in order to restrict the rotation operation of the rotation unit 63. For example, a magnetic material and a permanent magnet may be provided on a part of the rotating part 63 (for example, the outer surface of the guide wall 61a) and a part of the second bottom part, or a coil spring may be locked. That's fine.

As described above, when an elastic piece, a permanent magnet, a spring, or the like is used, the elastic piece or the rotating unit 63 is operated by the weight of the drug M, and then the dispensing of the drug M to the drug recovery unit 31a is completed. , Can automatically return to the original position.

Further, instead of providing the rotating portion 63 and the elastic piece, it is also possible to cope by lowering only the bottom plate 57. That is, in addition to the configuration shown in FIG. 3, a mechanism for raising and lowering only the bottom plate 57 is provided. Then, by lowering the bottom plate 57 from the state shown in FIG. 4C, a part of the bottom plate 57 is moved into the medicine recovery unit 31a. At this time, the medicine M is released from the contact state with the partition plate 20 with the bottom plate 57 sufficiently lowered. Thereby, the medicine M can be dispensed at a position sufficiently close to the bottom surface of the medicine collection unit 31a.

13 to 16, the case where the medicine storage member 51 is employed has been described. However, the configuration described here can also be employed in the medicine receiving unit 3 when the medicine storage member 51 is omitted. is there.
