At this time, the main controller 5 functions as an informing means, and distinguishes an inappropriate drug for which an inappropriate result was obtained from an appropriate drug for which an appropriate result was obtained. The divided bandage 33 including the divided package 42 to be inspected is conveyed downstream in the conveying direction by a divided bandage feeding device (not shown) provided downstream of the main body 29 of the packaging device in the conveying direction of the divided bandage. , are stored in a storage unit (not shown). When all the medicines stored in the sachets 42 have been inspected in the input hopper 28, the operation of the medicine sachet device 1 is stopped.

According to the above-described configuration, it is possible to accurately inspect whether or not the powder medicine supplied in the sachets 42 is correct or not, which cannot be judged visually, before the sachets 42 are accommodated. can be prevented. In addition, it is possible to inspect powdered drugs in which two or more types are mixed, and even if the type of drug is correct, it can be pointed out if the mixing ratio is different, and the accuracy of dispensing can be further improved.
In addition, by preventing the occurrence of dispensing failures, it is possible to deal with problems caused by improper operation of the device, and it is possible to eliminate the pharmacist's anxiety about the presence or absence of human error without deteriorating the work efficiency. .
In addition, in the present invention, all the medicines stored in all the packets 42 are inspected, so that the highest reliability can be obtained as an inspection result.

FIG. 8 shows a second embodiment of the invention. This second embodiment differs from the above-described first embodiment in that an intermediate hopper 54 for receiving a packet of powdered medicine supplied from the powdered medicine dividing device 18 is provided above the input hopper 28. and other configurations are the same. The intermediate hopper 54 functions as a portion that stores a package of medicine on the upstream side of the input hopper 28 that is the medicine storage portion. The intermediate hopper 54 is provided with a bottom plate 54a that functions as a retention member, and one end of the bottom plate 54a is rotatably supported by the intermediate hopper 54 via a support shaft. The intermediate hopper 54 selectively occupies a closed position indicated by a solid line and an open position indicated by a two-dot chain line in FIG. 8 by driving means such as a motor (not shown). A sealing member (not shown) is provided between the bottom plate 54a and the intermediate hopper 54, and when the powdered medicine is placed on the bottom plate 54a, the powdered medicine drops downward through the gap between the bottom plate 54a and the intermediate hopper 54. are prevented from doing so. The intermediate hopper 54 is made of the same material as the input hopper 28 .

The intermediate hopper 54 has a function of temporarily storing a packet of powdered medicine supplied from the powdered medicine dividing device 18 and then transferring the stored packet of powdered medicine to the input hopper 28 . By having the intermediate hopper 54 , it is possible to gain time until the powdered medicine for one packet supplied from the powdered medicine dividing device 18 is put into the feeding hopper 28 .
For example, when the packaging device 19 performs printing (including stamping) on the divided bandage 33, unevenness is generated in the divided bandage 33 after the medicine is supplied into the compartment of the divided bandage 33, and good printing cannot be performed. Therefore, printing must be completed before drug delivery to the compartment. However, if the conveying distance of the divided bandage 33 from the printing process to the medicine supply process does not match the medicine supply distance due to the configuration and layout of the apparatus, the timing of printing and medicine supply will not match, resulting in packaging defects. may occur. Therefore, by using the intermediate hopper 54, a buffer can be provided in the chemical supply process, and the timing of printing and chemical supply can be matched.

In the second embodiment, the inspection device 43 is arranged so as to be able to irradiate the medicine stored in the intermediate hopper 54 with light. inspect the drug stored in the According to the second embodiment, by inspecting the medicine discharged from the powder medicine packaging device 3 before it is stored in the input hopper 28, the same effects as in the first embodiment can be obtained. be able to.
In the second embodiment, the intermediate hopper 54 is configured to be capable of receiving the tablets and powdered medicine discharged from the tablet storage 2 and the powdered medicine packaging device 3. may be acceptable only as a powdered drug. In the second embodiment, the medicine discharged from the powdered medicine packaging device 3 is stored in the intermediate hopper 54 located upstream in the medicine discharge direction from the feeding hopper 28, and inspection is performed. As long as it is located upstream of 28 in the medicine discharge direction, it is not limited to the intermediate hopper 54, and any construction may be employed to store the medicine and carry out the inspection.

In the second embodiment, one intermediate hopper 54 is provided between the powdered medicine dividing device 18 and the input hopper 28, but two or more intermediate hoppers 54 may be provided. By providing a plurality of intermediate hoppers 54, the buffer provided in the chemical supply process can be set for a long period of time.
When a powdered drug is used as the drug, the powdered drug tends to adhere to objects due to static electricity or slight contamination and is likely to scatter. and adheres to each intermediate hopper 54 and decreases. Therefore, when inspecting medicine in a configuration using a plurality of intermediate hoppers 54, an inspection device 43 is provided at a position corresponding to the intermediate hopper 54 provided at the most upstream position in the conveying direction of the medicine. It is configured to inspect the drug stored in the. With this configuration, it is possible to inspect the most appropriate drug for dispensing information, patient information, and prescription information, thereby improving inspection accuracy.
