A container storage section for storing supply containers that do not contain pharmaceuticals, A weighing unit that measures the drug contained in the drug container into the supply container, The supply container can be set, and there are multiple discharge units that discharge the drug from the set supply container to a rotating dispensing tray, A transport unit that transports the supply container from the container storage unit to the weighing unit, and transports the supply container from the weighing unit to the discharge unit, A dispensing unit for dispensing the drug discharged into the aforementioned dispensing tray, In a drug packaging device equipped with, The weighing unit is capable of simultaneously weighing up to two of the supply containers. The transport unit is unable to transport the two supply containers from the weighing unit to the discharge unit in parallel. The discharge unit is capable of discharging the drugs from the two supply containers in parallel. The weighing unit starts weighing the first drug before weighing the second drug, which has a smaller target amount than the first drug. The drug packaging device is configured to execute a first process when the weighing of the second drug is completed faster than the weighing of the first drug while the next dispensing data has not been set, and to execute a second process when the weighing of the second drug is completed faster than the weighing of the first drug while the next dispensing data has been set. The first process is, After the weighing of the second drug is completed, the transport unit waits for the transport of the supply container containing the second drug. The transport unit, after completing the weighing of the first drug and the transport of the supply container containing the first drug to the discharge unit, then transports the supply container containing the second drug to the discharge unit. The second process described above is: After the weighing of the second drug is completed, the transport unit transports the supply container containing the second drug to the discharge unit before the transport of the supply container containing the first drug. A drug packaging apparatus characterized in that, after the transport of the supply container containing the first drug to the discharge section is completed, the transport section transports the supply container from the container storage section to the weighing section for weighing the third drug included in the next dispensing data.

Description

This invention primarily relates to a drug packaging device for measuring and packaging drugs contained in drug containers. Patent Document 1 discloses a drug packaging device for dispensing drugs. The drug packaging device comprises a weighing unit, a transport unit, a discharge unit, and a packaging unit. The weighing unit weighs the drug into an intermediate container. The transport unit transports the intermediate container to the discharge unit. The discharge unit discharges the drug contained in the intermediate container into a dispensing tray. The packaging unit distributes the drug discharged into the dispensing tray and packages it with packaging material. Furthermore, when multiple drugs are mixed and packaged, weighing is performed sequentially for each drug. Japanese Patent Publication No. 2021-29555 Means and effects for solving the problem The problems that this invention aims to solve are as described above. Next, the means for solving these problems and their effects will be explained. According to the aspects of the present invention, a drug packaging device having the following configuration is provided. That is, the drug packaging device comprises a weighing unit, a plurality of discharge units, a transport unit, and a packaging unit. The weighing unit weighs the drug contained in a drug container into a supply container. The discharge unit is capable of setting the supply container and discharges the drug from the set supply container into a distribution tray. The transport unit transports the supply container from the weighing unit to the discharge unit. The packaging unit packages the drug discharged into the distribution tray. When the weighing unit weighs at least a first drug and a second drug with a target amount less than the first drug, it starts weighing the first drug before weighing the second drug. This allows for faster dispensing by first measuring out larger quantities of medication, thus increasing work efficiency. In the aforementioned drug packaging device, the following configuration is preferable. Specifically, the weighing unit is capable of weighing multiple drugs in parallel. Weighing of the second drug begins before the weighing of the first drug is completed. This allows for weighing in parallel and in the correct order, further increasing work efficiency. In the aforementioned drug dispensing device, the following configuration is preferable. Specifically, if the weighing of the second drug is completed before the weighing of the first drug, the device waits for the transport of the supply container containing the second drug. After the weighing of the first drug and the transport of the supply container containing the first drug to the discharge section are completed, the supply container containing the second drug is transported to the discharge section. This prioritizes the excretion of the first drug, which takes longer to excrete, thus shortening the time it takes for all drugs to be excreted. In the aforementioned drug packaging device, if the weighing of the second drug is completed before the weighing of the first drug, it is preferable to transport the supply container containing the second drug to the discharge section before transporting the supply container containing the first drug. This allows the supply container to be moved from the weighing unit earlier, enabling the weighing of the next dose of medication to begin sooner. A schematic diagram showing a drug packaging device according to the first embodiment.Perspective view of the supply container.A flowchart illustrating the process of weighing and packaging in the correct order.A table showing an example of determining the weighing order based on the target quantity in the dispensing data.Timing charts for comparative examples and the first embodiment.Schematic diagrams showing drug packaging devices of the second and third embodiments.Timing charts for the second and third embodiments. Next, a first embodiment of the present invention will be described with reference to the drawings. Figure 1 is a schematic diagram showing a drug packaging device 1 of the first embodiment. The drug packaging device 1 is installed in a pharmacy or hospital. The drug packaging device 1 weighs and packages one or more drugs individually. The weighing and packaging of drugs performed by the drug packaging device 1 is based on dispensing data entered by the operator or received externally. Medication dispensing refers to taking out the required amount of medication from a medication container or similar. In this embodiment, dispensing is performed by weighing the medication supplied from the medication container. The medication packaging device 1 in this embodiment dispensing powdered medication (powder, granules, or granular medication). Furthermore, the medication packaging device 1 in this embodiment packages the dispensed powdered medication. However, the medication packaging device 1 may also be configured t
