Description of the Related Art Conventionally, as a medicine dispensing device for dispensing, there has been known a tablet dispensing machine and a powder dispensing machine, which have been advanced in automation, and a device for picking and extracting a medicine (Japanese Patent Laid-Open No. 2-309967). Of these, tablet packaging machines and powder packaging machines are
Various dispensing medicines are efficiently taken out and collected from a large number of medicine cassettes, but the handling targets are limited to loose tablets and unpackaged powdered medicines. On the other hand, a dispensing device using a method such as picking can handle a prepackaged medicine such as a PTP tablet, that is, a sheet pack in which tablets are packed.

[0003]

However, in taking out a medicine by picking, a picking mechanism composed of a plurality of members is appropriately operated and the picking mechanism is sequentially moved between a large number of drug cassettes. It is complicated and it is difficult to increase the processing efficiency.

On the other hand, a medicine dispensing device for dispensing a medicine by suction has been developed, which is disclosed as a sixth embodiment in Japanese Patent Application No. 10-197901 by the same applicant. This allows a pre-formulation such as a single medicine pack or a plurality of bundled medicine packs to be appropriately dispensed without damaging even a relatively simple structure. And if suction is established, P
It is also applicable to TP tablets.

However, in this dispensing medicine dispensing apparatus, the medicine cassette and the ejection mechanism are one-to-one, so that in order to handle various kinds of medicines, it is necessary to provide ejection mechanisms by the number of medicine cassettes. Then, it is necessary to connect a suction means to each of the extraction mechanisms. For this reason,
Even if the individual structures are simple, the intake pipes and the like arranged around them are complicated. Therefore, in improving the medicine dispensing device for dispensing so that various kinds of medicines can be dispensed, it is a problem to devise to maintain the advantages of the suction method.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to realize a medicine dispensing device for dispensing and dispensing various medicines by a simple structure. .

[0007]

The constitution, operation and effect of the dispensing device for dispensing medicine of the present invention which has been made to solve such problems will be described below.

The dispensing device for dispensing medicine according to the present invention (as described in the first aspect of the present invention) includes a plurality of medicine cassettes housed in a rotatable storage, and a dispensing position among the medicine cassettes. And a take-out mechanism for sucking out the dispensing medicine from the product.

In the dispensing medicine dispensing device having such a configuration, the dispensing medicine to be dispensed is sucked by the dispensing mechanism when the medicine cassette accommodating the dispensing medicine comes to the dispensing position with the rotation of the storage. Then, it is taken out of the medicine cassette. Thereby, even if the take-out mechanism, which has a lot of restrictions for handling the fluid and is likely to be complicated, is fixed, it can be shared by a plurality of medicine cassettes, and the number of medicine cassettes can be simplified. There is no need to extend intake pipes and the like in various directions. Therefore, according to the present invention, a medicine dispensing device for dispensing and dispensing various medicines for dispensing can be realized with a simple structure.

The dispensing device, the conveyor 13 to be carried out to the inspection department, and the like are stored. The controller 12 is an electronic control device composed of a computer such as a personal computer. The program control allows the controller 12 to perform not only the above-described control of the rotation driving unit 24 and the suction unit 60 but also the control of the transport conveyor 13 by a communication (not shown). This is performed based on prescription information and dispensing information obtained via a reading device such as a host computer or a barcode reader, or a manual operation unit.

The mode of use and operation of the dispensing device for dispensing medicine of this embodiment will be described with reference to the drawings. FIG. 1B shows an installation state when the apparatus is introduced into a pharmacy or the like, and FIG. 5 shows an appearance of a PTP tablet which is a typical example of a dispensing medicine to be dispensed. Also,
FIG. 6 shows the take-out mechanism 30 and the medicine cassette 4 just below it.
0 is a side view, and the taking-out operation of the medicine is illustrated by arrows AF.

When carrying in the installation location, the additional unit 1
0 and each dispensing medicine dispensing apparatus 20 are divided and carried in a separated state. Then, the additional unit 10 is first fixed, and the lower dispensing medicine dispensing device 20 is placed thereon. At this time, the positions of the chute 26 and the like are adjusted by using the positioning pins, and fixed by using the locking members. Then, in the same manner, the middle and upper dispensing medicine dispensing apparatuses 20 are set, and finally the top end is closed with the top plate 15. Thus, the installation work can be easily performed by a small number of people.

Then, in order to store the dispensing medicine 50 in the stock part 41 of the medicine cassette 40, first, the movable table 4
2 is lowered to the lowermost position, and a suitable number of dispensing medicines 50 are placed thereon. At this time, even if the dispensing agent 50 is a PTP tablet having a convex portion 52 in addition to the flat portion 51 (see FIG. 5A), the flat portion 51 is facing upward (FIG. 5A). (See FIG. 5 (b)) or whether it is down (see FIG. 5 (c)).

The medicines are accommodated in a large number of medicine cassettes 40 one after another according to the kind and the packaging form of the medicine, and the accommodated medicine cassettes 40 are stored in the appropriate medicine dispensing device 20 for dispensing. It is installed in the storage 23. In addition, the mounting position and the drug information of the mounted drug cassette 40 are set in the controller 12 manually using an operation console or the like or by automatic processing using a reading device or download. Thus, in addition to installing the medicine dispensing device 20 for dispensing, the setting of a large number of medicine cassettes 40 and various kinds of medicines for dispensing 50 is completed, and preparation for automatic dispensing is completed.

When a dispensing instruction is received in a state where the power is turned on and the operation is enabled, the controller 12 receives a prescription instruction from, for example, a host computer or the like.
Is received, the loading and unloading of the tray and the selective dispensing of the necessary dispensing medicine are performed under the control of the controller 12 based on the information. That is, for each prescription or patient, an empty tray 14 is carried into the additional unit 10 by the transport conveyor 13 or the like, and is placed immediately below the chute 26 (see the broken line in FIG. 2A).

Simultaneously or after that, in the medicine dispensing device 20 for dispensing, the storage box 23 is rotated, and the medicine cassette 40 containing the medicine 50 for dispensing selected based on the prescription information is taken out by the take-out mechanism 30. It moves to the removal position directly below. When the advancing / retracting drive unit 35 descends and comes into contact with and drives the rolling wheel 45 (see the arrow A in FIG. 6A), the movable table 42 rises and the dispensing medicine 50 is pushed up (FIG. 6). (See arrow B in (a)). At this time, the pad 34 descends in reverse (see the arrow C in FIG. 6B), and the surface on which the vent 34a is formed contacts the upper surface of the uppermost dispensing agent 50.

Further, in this state, the suction by the suction means 60 is performed. This suction is first performed with the switching valve 61 fully opened. Therefore, the dispensing drug 5 to be suctioned
In the case where 0 is stored with the flat portion 51 facing up, all the vents 34a are closed by the dispensing agent 50, so that the dispensing agent 50 is adsorbed on the pad 34 and the communication passage 64 In addition, the amount of air flowing through the restricting portion 62 is rapidly reduced to almost zero at all places. Then, the dispensing medicine 50 rises along with the pad 34 (see the arrow D in FIG. 6B), and is carried together with the pad 34 toward the chute 26 (arrow E in FIG. 6B). reference). Then, when the suction by the suction means 60 stops, it is thrown into the chute 26 from the opening 26a and falls toward the tray 14 waiting below (see the arrow F in FIG. 6B).

On the other hand, when the dispensing medicine 50 to be aspirated is stored with the convex portion 52 facing upward, the vent 3
4a is only partially closed. For this reason, the amount of air flowing through the communication passage 64 branched toward the closed vent hole 34a and the throttle portion 62 thereat becomes almost zero,
Since outside air flows in through the communication passage 64 leading to the unblocked vent 34a, the negative pressure required for adsorption cannot be obtained. This state continues even if a predetermined time determined based on the exhaust capability of the negative pressure source 70 and the like has elapsed. Therefore, after a lapse of a predetermined time, the switching valve 61 provided in the communication passage 64 where the ventilation does not stop is forcibly switched to the closed state under the control of the controller 12. Then, the negative pressure suction force is quickly increased, and the dispensing agent 50 is sufficiently adsorbed to the pad 34 by suction only through some of the vents 34a.
Thus, also in this case, the dispensing medicine 50 is reliably taken out from the take-out position and is dispensed to the tray 14.

Moreover, such dispensing operations are performed simultaneously and concurrently in the upper, middle and lower dispensing medicine dispensing apparatuses 20, so that the dispensing process can be completed quickly. Then, when all the desired medicines based on the prescription and the like are collected in the tray 14, the tray 14 is carried out to the inspection department or the like by the transport conveyor 13. In this way, the automatic dispensing of various medicines, by taking out using suction,
It is processed properly.

In addition, even after the start of use, when the dispensing medicine dispensing device 20 is added due to an increase in new medicines, the top plate 15 is once removed, and the upper dispensing medicine dispensing apparatus is dispensed. By setting the additional medicine dispensing device 20 for dispensing on the device 20, the device can be easily grown in the height direction. Furthermore, since the amount of use differs depending on the type of medicine, etc., when it is desired to arrange a frequently replenished medicine in a place where the work is easy, the medicine dispensing device 20 is dispensed with the medicine dispensing device 20 in addition to minutely replacing the medicine cassette 40. The arrangement can also be changed collectively, for example, by switching the top and bottom.
