BACKGROUND OF THE INVENTION
The present invention relates to a medicine for replenishing a tablet into a tablet storage part of a medicine packaging device for dispensing and packaging a tablet according to a prescription.Packaging equipmentAbout.
[0002]
[Prior art]
In hospitals and pharmacies, packaging devices for packaging drugs such as necessary tablets and powders are used according to doctors' prescriptions, and various types of such drug packaging devices are known. The medicine packaging device generally includes a medicine storage unit, a dispensing / conveying unit, a printer, a medicine bag seal part, a medicine bag supply part, a cutter, and the like.
[0003]
There are hundreds of kinds of medicines stored in the medicine storage section, and if these are used, it is natural that it is necessary to replenish the used medicine. For example, it is known from JP-A-4-102168. In the packaging device disclosed in this publication, a tablet case is removably inserted into a large number of storage compartments in which a medicine storage part is partitioned by a grid-like partition wall, and tablets are aligned and dispensed via a drive part in the tablet case. Then, the lower packaging unit is used for packaging.
[0004]
A predetermined amount of tablets are stored in the tablet case, and when the tablet is dispensed by controlling the drive unit according to a command from the control unit, the number of tablet cases in stock is confirmed by the support means based on the control operation. The number of stocks for each tablet case is retrieved by a retrieval means, and the retrieval result is displayed on a display device to facilitate tablet replenishment.
[0005]
[Problems to be solved by the invention]
By the way, in the inventory management device according to the above-mentioned patent gazette, the number of inventory in each tablet case can be confirmed and displayed by the support means, but the inventory management is to the extent that the displayed inventory number is less than the predetermined appropriate inventory number. It is possible to manually replace a tablet case lacking a tablet by knowing that this is different from other tablet cases.
[0006]
The situation is the same in other types of packaging devices, and the replenishment of drugs is in principle done manually. However, in any type of packaging device, the number of drug types increases, and in order to ensure a certain amount of drug stock for each type, the size of the drug container is increased as a whole.
[0007]
For this reason, in any type of packaging device, when replenishing the shortage of inventory, there is a storage part that is difficult for humans to reach, and it is necessary to move around the medicine storage part to replenish the medicine. In some cases, it is necessary to grind the medicine into the predetermined storage portion by groping. For this reason, the medicine replenishment work is extremely inefficient, and involves labor, time, and troublesomeness. In some rare cases, mistakes may be made in replenishing the adjacent storage portion by mistake.
[0008]
In consideration of such conventional problems, the present invention can efficiently replenish the medicine to any part of the medicine packaging device and reliably perform the replenishment processing.Providing a medicine packaging device that can be realized simply and at low costThis is the issue.

The storage position of the specific medicine to be read is read, and the unit is driven to move to a predetermined position based on the read signal. At this time, in order to detect whether or not the movement of the unit exactly coincides with the predetermined position, a signal representing the number of rotations or the travel amount of the motor is fed back to the arithmetic control unit 30, and the unit is thereby returned to the designated position. Sent.
[0031]
As shown in FIG. 1, a barcode reader 51 and a base plate 52 are provided outside the main body case 1, and the tablet container 53 is read by reading the barcode 54 displayed on the tablet container 53 on the base plate 52. It is possible to check whether the medicine in the medicine matches the one indicated. As shown in FIG. 7, the read signal of the barcode reader 51 is sent to the arithmetic control unit 30.
[0032]
Although not shown, the arithmetic control unit 30 is provided with a storage unit for storing various recording data. The storage unit stores and stores dispensing recording data and replenishment recording data. It can be displayed on a display device or can be printed on a printer (not shown). The dispensing record data includes a medicine name, a tablet number, a dispensing amount, a medicine type, a dispensing date and the like designated by a prescription for each patient. The replenishment record data is a record including the code symbol of the tablet case to be replenished, the code symbol of the tablet container storing the medicine, the code symbol of the tablet, the coordinate position of the tablet case, and the progress of the replenishment operation.
[0033]
In the medicine packaging apparatus according to the first embodiment having the above-described configuration, the medicine is replenished as follows with respect to the medicine shortage caused by the medicine use.
[0034]
First, a predetermined amount of tablets are stored in each of a large number of tablet cases 7 in the medicine packaging device, and these tablets are different or of the same type for each tablet case 7, and each tablet case 7 stores a medicine. It is inserted in part 2. When the medicine information from the host computer 100 is sent to the medicine packaging apparatus prepared in this way, the tablet is dispensed through the dispensing mechanism 36 of the designated tablet case 7, and is sent to the packaging apparatus to be sent to each patient. Each time a necessary amount of tablets is packed in a packaging sheet.
[0035]
In this way, when tablets necessary for a large number of patients are dispensed from the medicine storage unit 2, the tablet case 7 in a specific partition part becomes less than the number of tablets stored in the tablet case 7 and needs to be replenished. . However, the set storage number may be either when there is no tablet completely or when the remaining number of tablets becomes a predetermined number or less. The present invention automatically replenishes the drug in such a case, and specifically, replenishment is performed as follows according to the flowchart of FIG.
[0036]
Step S₁First, the quantity of medicine is read. In addition to the control according to the flowchart shown in the figure, this quantity count is performed for each section position in the arithmetic control unit 8 based on a switch signal that is sent each time a tablet is dispensed from the tablet case 7 one by one by the aforementioned dispensing mechanism. It is assumed that this is performed by subtraction by the counter unit from the maximum amount of tablets stored in the tablet case 7.
[0037]
If the above quantity reading is less than the set number of tablets stored in any tablet case 7, a drug shortage has occurred and step S₂If it is detected that the number is less than the set number,_ThreeThen, the name of the missing drug (code) and the corresponding section position number (coordinate) are displayed on the display device 31, and the replenishment hopper 19 moves to the standby position. This standby position may be on a specific position of an arbitrary partition position of the medicine container 2, or may be provided outside the main body case 1 although not shown.
[0038]
When the shortage status of the tablet in the specific section position is displayed, the necessary amount is put into the replenishment hopper 19 from the tablet container 53 storing the corresponding tablet. The bar code reader 51 reads the bar code symbol 54 displayed on the tablet container 53 to see if the type of the tablet that has been sold matches (step S)._Five), The code symbol is the code symbol of the missing tablet and step S₆It is done by collating with.
[0039]
If the code symbols match, a predetermined number of tablets are taken out from the tablet container 53 and transferred to the replenishment hopper 19. And step S₇Then, it is checked whether or not the medicine has been charged into the hopper 19, and the replenishment hopper 19 moves. Although the illustration of the medicine input completion check is omitted, a switch signal may be input manually, for example.
[0040]
Step S₈The replenishment hopper 19 moves together with the replenishment unit 4 and moves the wheel 20 provided in the replenishment unit 4 to the step S.₉Thus, the opening / closing lid 7a of the medicine container 2 is made to coincide with the position of the opening / closing lever 73. Then, when the open / close lever 73 is pushed down so as to ride on the open / close lever 73, the open / close lid is opened. In this state, the bottom plate 19a at the bottom of the replenishment hopper 19 is opened by the hopper motor 34, and the tablets in the replenishment hopper 19 are dropped into a predetermined compartment and replenished (step S)._Ten).
[0041]
Next, step S₁₁The completion of drug supply is checked. Although not shown, this completion check is performed by providing a height detection sensor including a light emission and light reception sensor at a predetermined position above the tablet storage portion of the tablet case 7. Step S when replenishment is completed₁₂Then, the supply hopper 19 is moved to the standby position, and the operation is completed. However, the above operation is a case where a shortage occurs in one tablet case 7. When a shortage occurs in a plurality of tablet cases 7, the above operation is repeated for each tablet case 7.
[0042]
In the above embodiment, the collation between the tablet container and the missing drug is based on the condition that the barcode symbol displayed on the tablet container is read and collated, but the label is displayed on the container regardless of the barcode symbol. The pharmacist may read the content of the contents and confirm that the tablet in the container matches the missing drug.
[0043]
Various data necessary for the above replenishment work is stored in the storage unit, but each stored data is stored and saved as replenishment record data, and displayed on a display unit later or displayed on a printer as necessary. Is done. This replenishment record data is preferably displayed in a list format including a replenishment collation result indicating whether or not the tablet to be replenished in the replenishment operation has been correctly replenished to the tablet case.
[0044]
At that time, at least the following items are included in the supply collation result list.
[0045]
・ Pill container identification code (bar code) symbol
・ Tablet case identification code
・ Judgment result of match / mismatch in replenishment verification
・ Supply amount, tablet identification code symbol
-Progress of replenishment verification (error signal, reset signal in case of mismatch as a result of verification, reading of identification code such as medicine bottle again, time elapsed).
[0046]
FIGS. 9-14 shows the schematic and detail figure about 2nd Embodiment of a chemical | medical agent packaging apparatus. In this embodiment as well, the medicine supply device is provided as in the first embodiment. However, in this embodiment, the medicine supply unit 4 is used as the packaging device employs the rotary drum type medicine storage unit 2. The difference is that it is equipped with a liftable type.
[0047]
As shown in FIGS. 9 and 10, the medicine container 2 is provided in the upper half of the main body case 1, and the packaging unit 3 is provided in the lower half, so that the space that can be formed at the four corners of the medicine container 2 and the main body case 1.

The lower support disc 2e with which the lower end of each tablet dispensing passage 2d abuts communicates with a hopper 2g below the disc through an opening 2f corresponding to each passage.
[0049]
The inner and outer rotors 2b and 2a are provided with a pinion (not shown) below the motors 21M (outside) and 2M '(inside) provided on the center frame where the support frame 1F fixed to the body case 1 crosses. Of these, the inner rotor 2b can be rotated about 360 ° and the outer rotor 2a can be rotated about 300 ° by engaging teeth formed on the outer circumferences of the outer disks 2e and 2e. As described above, the inner and outer rotors are of the rotary type. The inner rotor 2b is provided with the tablet compartment 2c over the entire circumference, but the outer rotor 2a is cylindrical as shown in FIG. A part of the tablet-shaped tablet compartment 2c is thinned out, and an opening / closing door (not shown) is provided in the main body case at a position corresponding to the surface of the tablet compartment. This is because it is possible to manually supply tablets to any of 2c. Each tablet compartment 2c can be pulled out in the radial direction of the inner and outer rotors 2b, 2a. In the case of manual work, tablets are replenished in a state where the predetermined compartment 2c is pulled out.
[0050]
FIG. 11 shows an example of the tablet compartment 2c. The compartment 2 c is provided with a lid 22 at the top of the case 21, and a front edge plate 22 a at the front end of the lid 22. A hopper plate 24 for securing the tablet storage space 23 is provided in the case, and a rotary tablet feed alignment ball 25 having an inclined surface corresponding to the hopper inclination is provided. On the outer periphery of the alignment balls 25, feed holes 25a are provided obliquely at a constant pitch so that the tablets P are fed in an ant hell format.
[0051]
A restriction plate 25c for restricting the dispensing of tablets and a small hole 27 corresponding to the center of the rotation are provided at a predetermined position of the hopper plate 24, and the alignment balls 25 are arranged in a phase where the feed hole 25a coincides with the small hole 27. Is rotated, only one tablet P is dispensed into the passage 28, and the dispensing of the tablet P above the restriction plate 25c is restricted. Then, the tablet P is dispensed to the dispensing passage 2d through the opening 28a at the lower end of the passage 28. Reference numeral 25b denotes an entire circumferential groove into which the tip of the limiting plate is fitted.
[0052]

A detection sensor S for confirming the passage of the tablet P is provided in the middle of the passage 28.₁Is a light emitting element, S₂Is a light receiving element. When the passing signal is detected every time the tablet P dispensed by the detection sensor S passes, it is sent to the control unit 18, and the number of stored tablets P stored in each tablet compartment 2c, or a predetermined number. It is detected whether:
[0053]
12 and 13 schematically show the drug supply units 4 and 4 '. As shown in FIG. 12, only one rotary medicine replenishment unit 4 is provided so as to be shared with the inner and outer rotors, or this is dedicated to the inner rotor 2b and is independent of the outer rotor 2a. A replenishment unit 4 'may be provided exclusively.
[0054]
As shown in FIG. 13 (a), the dual-purpose type drug supply unit 4 includes an elevator platform 42 that engages with an elevator rod 41 that is fixed to a main body case or a floor board at the top and bottom of the drug storage unit 2 and can move up and down. Elevating motor 43 that vertically moves, rotating arm 44 that is rotatably engaged with the tip of the elevator 42, motor 45 that rotates the same, replenishment hopper 46 that is rotatably attached to the tip of the rotating arm 44, and inclination driving thereof A hopper motor 47 and a lid opening plate 48 for opening and closing the lid of the medicine compartment provided at the upper end of the rotating arm 44 are provided.
[0055]
As shown in FIG. 13B, the medicine replenishing unit 4 ′ dedicated to the outer rotor 2a differs from the above-mentioned dual-use type in that the rotating arm 44 and the rotating motor 45 are not provided, but the other parts are exactly the same. The same members are denoted by the same reference numerals in the drawings, and the description thereof is omitted.
[0056]
The basic configuration of the packaging device 3 below the medicine container 2 is the same as that of the first embodiment, and the shape of the hopper 9 below the medicine container 2, the guide 10, and the conveyor 11 are provided. It is slightly different in that it is not, but it is the same in other points, and the same function members are denoted by the same reference numerals and description thereof is omitted.
[0057]
FIG. 14 shows details of the replenishment hopper 46 provided on the rotating arm 44. As shown in the figure, the medicine stored in the replenishment hopper 46 is tilted around the shaft of the gear 46a that is rotationally driven by the pinion 47a at the output shaft end of the hopper motor 47, and is put into the tablet compartment 2c.
[0058]
In the medicine packaging apparatus of the second embodiment having the above-described configuration, medicines based on prescriptions from the tablet compartments 2c of the outer rotors 2b and 2a in the medicine storage unit 2 in an arbitrary phase position when packaging medicines. It is basically the same as the case of the first embodiment that the necessary tablets are dispensed according to the instruction of the information and are sequentially packaged on the packaging sheet by the packaging unit 3.
[0059]
However, since the inner and outer rotors 2b and 2a are separate tablet storage compartments, the storage section of the operation control unit corresponding thereto corresponds to the storage compartment obtained by expanding the inner and outer rotors 2b and 2a in a planar shape. This is different from the first embodiment in that it is stored separately in two memory map areas.
[0060]
Further, since the medicine storage unit 2 is in the form of a drum, the outer rotors 2b and 2a are respectively provided with the designated tablet compartments 2c as the medicine supply unit 4 or the same as in the case where the medicine is supplied manually. A command is issued from the control unit 8 to rotate and stop as necessary so as to reach the position 4 ′.
[0061]
In the above automatic medicine supply, when only the dual-purpose medicine supply unit 4 is installed for the inner and outer rotors 2b, 2a, tablets are automatically supplied to the tablet compartment 2c of the inner rotor 2b as shown in FIG. Therefore, the replenishment is performed in a state where the outer rotor 2a is rotated so that the portion where the outer rotor 2a is fan-shaped and a part of the tablet compartment is omitted corresponds to the tip of the medicine replenishment unit 4. The outer rotor 2a rotates with respect to the tablet compartment 2c of the outer rotor 2a regardless of the inner rotor 2b, and the predetermined tablet compartment 2c is replenished.
[0062]
When the replenishing units 4 and 4 'for replenishing the medicine independently to the inner and outer rotors 2b and 2a are provided, the rotation of the unit 4 for the inner rotor 2a is performed when the medicine is replenished to the tablet compartment 2c of the outer rotor 2a. The arm 44 is swung outward as indicated by the alternate long and short dash line in FIG. 12 so as not to obstruct the rotation of the outer rotor 2a.
[0063]
When the medicine is replenished by the replenishing unit 4 or 4 ′, the lift 42 is moved by the motor 43 when the row of the tablet compartments 2 c provided in the upper and lower stages rotates in front of the replenishing unit 4 or 4 ′. By driving, the lid 22 of each tablet compartment 2c is opened by using the movement that the lid opening plate 48 at the tip of the lifting platform 42 or the rotating arm 44 rises in this embodiment. In this state, the replenishment hopper 46 is tilted to replenish tablets.
[0064]
In addition, except when raising and lowering the replenishment unit to replenish tablets to the specific tablet compartment 2c, the lid 42 or the rotary arm 44 of the replenishment units 4 and 4 'has a lid opening plate 48 at the tip thereof for each tablet compartment. The rotary motor 45 or 45 ′ is rotated slightly outward so as to be positioned outside the outer peripheral radius of the lid front edge 22a so as not to be caught by the lid front edge 22a of the chamber 2c. Therefore, when the tablet is replenished, it is lifted while maintaining this rotational phase position, and when it comes within the specified depth range of the tablet compartment 2c, the lifting platform is swung out to the rotor side.
[0065]
Also in this embodiment, it is premised that tablets are replenished into the replenishment hopper 46 in advance, but at that time, as shown in FIG. 9, the barcode 54 displayed on the tablet storage container 53 is replaced with a barcode reader. 51, the code data and the medicine specified by the above-mentioned medicine prescription are collated and confirmed and displayed on the display device. When the coincidence is confirmed, the replenishment hopper 46 is replenished with the necessary amount. . Of course, it goes without saying that such a collation confirmation operation may be performed by visual confirmation by a pharmacist instead of confirmation by bar code display.

As shown in the drawing, the front end edges 22a of the respective drug compartments 2c are provided diagonally to each other, and the lid opening plate 48 does not hit the front end edge 22a at the intermediate position shown in the figure, and the lifting platform 42 moves up and down. It can be done. Therefore, when the elevating table 42 moves by moving the slide table 40, and the lid opening plate 48 comes to the position of the alternate long and short dash line, the lid opening plate 48 comes into contact with the front edge 22a and the lid 22 is opened.
[0072]
The lid opening plate 48 is a narrow projecting plate, and the front end edge 22a of the corresponding medicine compartment 2c is also substantially the same width. When the lid is opened, each of the replenishing units 4, 4 ″ is accurately Since the position is stopped in alignment with the front of the medicine compartment 2c, the lid 22 is opened when the replenishment unit 4, 4 ″ is raised only at that position when the lid is opened. Therefore, the replenishment unit 4 in a position slightly avoiding the position of the front end edge 22a of the lid 22 in the middle of rising and lowering from another position to approach the specific drug compartment 2c for opening the specific drug compartment 2c. 4 ″ should be raised and lowered.
[0073]
As shown in FIG. 15, each of the drawer shelves A, B, C, and D of the third embodiment has a display lamp 2._LAnd a small indicator lamp 2 on the lower front of each drug compartment provided in each drawer shelf._KAre provided. When tablet replenishment is required, a specific drawer shelf and a medicine compartment are turned on in response to a command from the computer so that they can be immediately visually confirmed from the outside.
