Means and effects to solve problems

From the viewpoint of the present invention, a drug supply device having the following configuration is provided. That is, this drug supply device includes a weighing unit and a discharging unit. The weighing unit weighs the drug in the drug container set in the first position into the intermediate container set in the second position according to the dispensing data. The discharging unit discharges the drug weighed into the intermediate container by the weighing unit. The intermediate container can be set in the first position. When the weighing unit supplies the drug in the drug container to the intermediate container in excess of the target amount based on the dispensing data, the intermediate container is set in the first position and is different from the intermediate container. The other container is set in the second position, and the drug in the intermediate container is discharged to the other container in the second position by the weighing unit.

As a result, when the medicine is excessively supplied to the intermediate container by the weighing unit, the amount of the medicine in the intermediate container can be reduced by using the weighing unit. Therefore, the drug can be smoothly supplied.

The drug supply device preferably has the following configuration. That is, the drug container can be set as the other container at the second position. By the weighing unit, the drug in the intermediate container can be discharged to the drug container in which the drug is supplied to the intermediate container.

Explanatory drawing which shows the state which the position of a container is changed when the drug is supplied from a drug container to an intermediate container in excess of a target amount. A flowchart showing a process related to weighing of a drug. The flowchart which shows the continuation processing of FIG.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view of a drug supply device 1 according to an embodiment of the present invention. FIG. 2 is a block diagram showing an electrical configuration of the drug supply device 1.

The drug supply device 1 shown in FIG. 1 can weigh one or a plurality of drugs and supply them to the outside. Weighing the drug means taking out the required amount of the drug contained in the drug container or the like. In the present embodiment, the weighing is performed by weighing the drug supplied from the drug container. The drug supply device 1 of the present embodiment weighs a powder (powder-like, fine-grained, or granular drug) as a drug. Further, the drug packaging device may be further provided with a packaging device for packaging the drug weighed by the drug supply device 1. In this case, the drug packaging device may be configured to be capable of packaging tablets in addition to the powder.

The drug weighing performed by the drug supply device 1 is performed based on the drug information included in the dispensing data input by the operator.

As shown in FIG. 1, the drug supply device 1 includes a storage unit 11, a transport unit 14, a drug container 15, a weighing unit 18, a discharge unit 32, and a control unit 50.

The storage unit 11 can store a plurality of intermediate containers 91 before accommodating the drug. The intermediate container 91 is prepared for accommodating the drug to be weighed and transporting it to each part of the drug supply device 1. Further, the intermediate container 91 can also be used to store the weighed drug and carry it to another drug packaging device when the weighed drug is not packaged.

The transport unit 14 can transport the intermediate container 91. Specifically, the transport unit 14 includes a container holding unit for holding the intermediate container 91. The container holding portion is configured to be movable along a rail provided in the drug supply device 1. The transport unit 14 transports the intermediate container 91 by moving the container holding portion along the rail while the intermediate container 91 is held by the container holding portion.

The transport unit 14 can also transport the drug container 15, which will be described later. Details will be described later.

In the present embodiment, the intermediate container 91 and the drug container 15 are transported by a common transport unit 14. Therefore, in each of the two types of containers, it is preferable that the portion attached to the transport unit 14 (container holding unit) has the same configuration because the configuration of the transport unit 14 can be simplified.

There are various configurations in which the transport unit 14 holds the container. For example, the container may be gripped by a chuck, or the container may be sucked and held. Further, for example, a container holding portion may be provided at the tip of a stretchable or rotatable arm, and the position of the container holding portion may be changed by expanding or contracting or rotating the arm. In this case, the rail can be omitted.

The drug container 15 substantially functions as a source of the drug to be weighed. At the bottom of each drug container 15, an opening is formed for discharging and supplying the drug to the outside of the container.

The moving mechanism 17 can move the plurality of drug containers 15 to a position where weighing is performed. The moving mechanism 17 is provided with a retainer to which the drug container 15 can be attached and detached, and the drug container 15 can be moved through the retainer, for example.

The weighing unit 18 can weigh the drug. The weighing unit 18 includes a drug supply mechanism 18a, a mounting table 18b, and a detection unit 18c.

The drug supply mechanism 18a can supply the drug from the drug container 15 to the intermediate container 91. The drug supply mechanism 18a acts on the drug container 15 arranged at a predetermined position by the moving mechanism 17 to supply the stored drug downward.

Specifically, the above-mentioned drug container 15 includes a shielding member (first opening / closing member) 22 for opening / closing the opening. The shielding member 22 is normally closed, but when weighing is performed by the weighing unit 18, the shielding member 22 is opened by driving an appropriate actuator (for example, an electric motor) 24 provided in the drug supply mechanism 18a. Is done. By vibrating the drug container 15 with, for example, a vibration motor (not shown) with the opening open, the drug contained in the drug container 15 can be dropped downward.

The drug container 15 includes an input member (not shown) for inputting the driving force of the actuator 24. This input member can be, for example, a rod-shaped member. The shielding member 22 is connected to the input member by, for example, a link mechanism. When the input member is driven by the actuator 24, the shielding member 22 can be opened and closed in conjunction with this.

The mounting table 18b is arranged below the holding body included in the moving mechanism 17. The intermediate container 91 can be placed on the mounting table 18b. The transport unit 14 can transport the intermediate container 91 held by the container holding unit and place it on the mounting table 18b or remove it from the mounting table 18b. The drug container 15 can be placed on the mounting table 18b. The transport unit 14 can transport the drug container 15 held in the container holding portion and place it on the mounting table 18b or remove it from the mounting table 18b.

The detection unit 18c can measure the drug inside the container with the intermediate container 91 mounted on the mounting table 18b. In other words, the mounting table 18b and the detection unit 18c are configured as an electronic balance, and the mounting table 18b corresponds to a portion of the weighing pan in the electronic balance. The detection unit 18c can be configured as, for example, an electromagnetic type or load cell type load sensor.

With the drug container 15 moved above the mounting table 18b by the above-mentioned moving mechanism 17, the weighing unit 18 is controlled by the control unit 50 so as to weigh a predetermined target amount of the drug indicated by the drug information. .. After that, the control unit 50 supplies the drug in the drug container 15 to the intermediate container 91 mounted on the mounting table 18b, and measures the supplied drug by the detection unit 18c.

The discharge unit 32 discharges the medicine weighed into the intermediate container 91. The discharge unit 32 includes a first discharge unit 32a and a second discharge unit 32b.

The first discharge unit 32a discharges the medicine weighed into the intermediate container 91 into the packaging device (not shown) further provided in the medicine supply device 1. In this packaging device, the medicines weighed by the weighing unit 18 and discharged by the first discharging unit 32a can be packaged in predetermined amounts. Since the configuration of the packaging device is known, the description thereof will be omitted.

The second discharge unit 32b makes it possible to take out the intermediate container 91 containing the medicine weighed by the weighing unit 18 to the outside of the medicine supply device 1.

The control unit 50 can control each unit (specifically, the weighing unit 18, the discharging unit 32, etc.) of the drug supply device 1 based on the dispensing data.

More specifically, the control unit 50 is configured as a known computer, and includes an arithmetic unit such as a CPU, a storage device such as a flash memory or a hard disk, and an input / output unit for communicating with the outside. Various programs and setting values are stored in the storage device. The arithmetic unit reads various programs and the like from the storage device, and based on the detection values of the sensors provided in each part of the drug supply device 1 and various set values stored in the storage device, each part of the drug supply device 1 Control the operation.

Next, with reference to FIG. 1, various positions set in the drug supply device 1 will be described.

The first position P1 is a position where the drug container 15 in which the target drug is stored is set when the drug is weighed in the weighing unit 18. The first position P1 is located above the second position P2 described later.

The second position P2 is a position where the intermediate container 91 is set when the drug is weighed in the weighing unit 18.

The storage position P3 is a position in the storage unit 11 where the intermediate container 91 before accommodating the drug can stand by.

The first position P1, the second position P2, and the storage position P3 can all serve as a transport source and a transport destination of the intermediate container 91 by the transport unit 14. Further, the transport unit 14 can transport not only the intermediate container 91 but also the drug container 15 between at least the first position P1 and the second position P2.

Next, a configuration for reducing the amount of the drug once weighed in the intermediate container 91 will be described.

Normally, the weighing unit 18 is controlled so that the amount of the drug corresponding to the target amount is weighed from the drug container 15 to the intermediate container 91 while monitoring the detection result of the detection unit 18c. However, when the drug is actually weighed from the drug container 15 to the intermediate container 91, the drug is excessively discharged from the drug container 15 due to, for example, the drug being supplied in a lump or vibration being applied to the device, and the target amount. May be exceeded.

In the present embodiment, in consideration of this case, the drug contained in the intermediate container 91 can be discharged and reduced.

Specifically, the bottom of each intermediate container 91 is formed with an opening for discharging the drug to the outside of the container. Further, the intermediate container 91 includes a shielding member (second opening / closing member) 95 for opening / closing the opening, and an input member for inputting the driving force of the actuator 24. Since the opening of the intermediate container 91, the shielding member 95, and the input member are substantially the same as the configuration of the opening of the drug container 15, the shielding member 22, and the input member, the description thereof will be omitted.

The intermediate container 91 is usually set at the second position P2 to receive the drug supply from the drug container 15. However, the intermediate container 91 can also be set at the first position P1 for discharging the drug. When the actuator 24 is driven while the intermediate container 91 is set at the first position P1, the shielding member 95 is opened. By vibrating the intermediate container 91 with, for example, a vibration motor (not shown) in the state where the opening is opened, the drug contained in the intermediate container 91 can be dropped downward.

The drug container 15 is usually set at the first position P1 to supply the drug to the intermediate container 91. However, the drug container 15 can also be set at the second position P2 for receiving the discharged drug. The drug container 15 is configured so that not only the bottom surface but also the upper surface can be opened and closed, and the upper surface is normally closed. However, when the drug container 15 is set at the second position P2, the upper surface is opened by the actuator (not shown).

With the above configuration, the weighing unit 18 discharges the drug inside the intermediate container 91 to the drug container 15 in a state where the intermediate container 91 is set at the first position P1 and the drug container 15 is set at the second position P2. can do. Further, since the weight of the drug container 15 is measured by the detection unit 18c in the process of this discharge, a required amount of drug can be discharged from the intermediate container 91.

Next, the operation of the drug supply device 1 when weighing the drug will be described.

The control unit 50 controls the transport unit 14 to transport the intermediate container 91 waiting at the storage position P3 of the storage unit 11 to the second position P2 of the weighing unit 18 (step S101). Almost at the same time, the control unit 50 controls the drug supply mechanism 18a of the weighing unit 18 to move the drug container 15 containing the drug indicated by the drug information included in the dispensing data to the first position P1 ( Step S102).

The control unit 50 confirms that the intermediate container 91 is in the second position P2 and the drug container 15 is in the first position P1 (step S103, step S104). This confirmation can be performed by a known sensor (not shown). After that, the control unit 50 controls the drug supply mechanism 18a, opens the shielding member 22 by the actuator 24, and starts supplying the drug from the drug container 15 to the intermediate container 91 (step S105). This state is shown in FIG.

While the drug is being supplied, the control unit 50 determines whether or not the measured amount calculated by the weighing unit 18 matches the target amount based on the dispensing data (step S106). If they match, the control unit 50 controls the actuator 24 so as to close the shielding member 22, and also controls the transport unit 14 to transport the intermediate container 91 from the second position P2 to the first discharge unit 32a. (Step S107). When the intermediate container 91 arrives at the first discharge unit 32a, the control unit 50 controls the discharge unit 32 and discharges the drug weighed into the intermediate container 91 by the first discharge unit 32a (step S108). The control unit 50 controls the moving mechanism 17 to return the drug container 15 from the first position P1 to the original position (step S109). The intermediate container 91 in which the chemicals have been discharged in the first discharge unit 32a is returned to the storage position P3 after performing appropriate work such as cleaning. Further, in step S107, the transport unit 14 may be controlled to transport the intermediate container 91 from the second position P2 to the second discharge unit 32b. In this case, when the intermediate container 91 arrives at the second discharge unit 32b, the control unit 50 waits for the intermediate container 91 to be taken out of the drug supply device 1. The intermediate container 91, which has finished supplying the weighed drug to the other drug packaging device, is manually returned to the storage position P3 after performing appropriate work such as cleaning.

If the measurement amount does not match the target amount in the determination in step S106, the control unit 50 determines whether or not the measurement amount exceeds the target amount (step S110). If the measured quantity does not exceed the target quantity, the process returns to step S106.

If the measured amount exceeds the target amount in the determination of step S110, the control unit 50 controls the actuator 24 so as to close the shielding member 22, obtains the excess amount of the drug by calculation, and appropriately stores the storage unit. (Step S111 in FIG. 5). The excess amount can be obtained by subtracting the target amount from the measured amount. The control unit 50 controls the transport unit 14 to switch the positions of the drug container 15 at the first position P1 and the intermediate container 91 at the second position P2 (step S112, step S113). Specifically, the transport unit 14 temporarily retracts the drug container 15 at the first position P1 to another appropriate place. After that, the transport unit 14 transports the intermediate container 91 to the first position P1, and further conveys the retracted drug container 15 to the second position P2.

The control unit 50 confirms that the intermediate container 91 is in the first position P1 and the drug container 15 is in the second position P2, as in steps S103 and S104 described above (steps S114 and S115). After that, the control unit 50 controls the drug supply mechanism 18a, opens the shielding member 95 by the actuator 24, and starts discharging the drug from the intermediate container 91 to the drug container 15 (step S116). This state is shown in FIG.

This drug is discharged until the amount of the drug weighed in excess of the target amount in the intermediate container 91 is discharged from the intermediate container 91. Specifically, the weight of the drug container 15 at the second position P2 is monitored by the detection unit 18c of the weighing unit 18, and when the increase in the measured amount matches the above excess amount, the discharge of the drug is stopped. Will be done.

The control unit 50 waits until the discharge of the excess amount of the drug is completed (step S117). When it is determined that the discharge of the drug is completed, the control unit 50 controls the actuator 24 so as to close the shielding member 95, and also controls the transport unit 14, so that the intermediate container 91 is moved from the first position P1 to the first discharge unit 32a. (Step S118). When the intermediate container 91 arrives at the first discharge unit 32a, the control unit 50 controls the first discharge unit 32a and discharges the drug weighed into the intermediate container 91 by the first discharge unit 32a (step S119). .. The control unit 50 controls the transport unit 14 and the moving mechanism 17 to return the drug container 15 from the second position P2 to the original position via the first position P1 (step S120). The intermediate container 91 in which the chemicals have been discharged in the first discharge unit 32a is returned to the storage position P3 after performing appropriate work such as cleaning. Further, in step S118, the transport unit 14 may be controlled to transport the intermediate container 91 from the first position P1 to the second discharge unit 32b. In this case, when the intermediate container 91 arrives at the second discharge unit 32b, the control unit 50 waits for the intermediate container 91 to be taken out of the drug supply device 1. The intermediate container 91, which has finished supplying the weighed drug to the other drug packaging device, is manually returned to the storage position P3 after performing appropriate work such as cleaning.

As described above, in the configuration of the present embodiment, even if an amount of the drug exceeding the target amount is supplied to the intermediate container 91 for some reason, the excess amount is returned to the original drug container 15 and the subsequent operation is continued. be able to. Therefore, it is possible to effectively suppress a decrease in the operating efficiency of the device and prevent waste of the drug.

Further, since the weighing unit 18 is used to discharge the excess amount from the intermediate container 91, the above effect can be realized without significantly complicating the configuration. Further, the actuator 24 of the weighing unit 18 can open the shielding member 95 of the intermediate container 91 in exactly the same operation as when opening the shielding member 22 of the drug container 15. Therefore, the mechanism for driving can be simplified.

As described above, the drug supply device 1 of the present embodiment includes a weighing unit 18 and a discharging unit 32. The weighing unit 18 weighs the medicine in the medicine container 15 set in the first position P1 into the intermediate container 91 set in the second position P2 according to the dispensing data. The discharge unit 32 discharges the drug weighed into the intermediate container 91 by the weighing unit 18. An intermediate container 91 can be set in the first position P1. When the weighing unit 18 supplies the drug in the drug container 15 to the intermediate container 91 in excess of the target amount based on the dispensing data, the intermediate container 91 is set in the first position P1 and is different from the container 91. The drug container 15 is set at the second position P2, and the drug in the intermediate container 91 is discharged to the container at the second position P2 by the weighing unit 18.

As a result, when the medicine is excessively supplied to the intermediate container 91 by the weighing unit 18 (when the medicine is supplied to the intermediate container 91 in excess of the target amount), the amount of the medicine in the intermediate container 91 is used by the weighing unit 18. Can be reduced. As a result, in such a case, the amount of the drug in the intermediate container 91 can be appropriately adjusted, and the drug in the intermediate container 91 can be used efficiently.

Further, in the drug supply device 1 of the present embodiment, the drug container 15 can be set at the second position P2. The weighing unit 18 can discharge the drug in the intermediate container 91 to the drug container 15 that supplies the drug to the intermediate container 91.

As a result, the excess drug can be returned from the intermediate container 91 to the original drug container 15, so that the waste of the drug can be reduced.

Further, the drug supply device 1 of the present embodiment includes a transport unit 14. The transport unit 14 is set in the first position P1, and the intermediate container 91 after the amount of the drug exceeding the target amount is discharged into the drug container 15 in the second position P2 is discharged from the first position P1 to the discharge unit 32. Transport to. When the transport unit 14 transports the intermediate container 91 to the discharge unit 32, the discharge unit 32 discharges the drug in the intermediate container 91.

As a result, the drug in the intermediate container 91 can be discharged by the discharge unit 32 after the amount of the drug to be stored is corrected after the fact. Further, the drug in the intermediate container 91 can be used in another drug packaging device.

Further, in the drug supply device 1 of the present embodiment, the drug container 15 includes a shielding member 22 that opens and closes to discharge the drug. The intermediate container 91 includes a shielding member 95 that opens and closes to discharge the drug. The shielding members 22 and 95 of the two containers are driven by a common actuator 24.

As a result, the shielding member 95 of the intermediate container 91 can be opened by the drive mechanism that opens the shielding member 22 for discharging the drug from the drug container 15. As a result, a simple configuration of the weighing unit 18 can be realized.

Although the preferred embodiment of the present invention has been described above, the above configuration can be changed as follows, for example.

The discharge destination container in which the excess amount with respect to the target amount is discharged from the intermediate container 91 is not limited to the original drug container 15, and may be other containers. As the discharge destination container, for example, another intermediate container 91 or another container provided outside the drug supply device 1 can be considered. When a container outside the drug supply device 1 is used, this container is carried to the second position P2 by an operator or the like and set.

The flowcharts shown in FIGS. 4 and 5 are examples, and the order of some processes can be changed or other processes can be added.

In step S117 of FIG. 5, it is conceivable that an amount exceeding the required amount is discharged from the intermediate container 91. In this case, the positions of the intermediate container 91 and the drug container 15 may be exchanged again, and the drug corresponding to the excess discharge amount may be weighed again into the intermediate container 91. In step S117 of FIG. 5, the entire amount of the drug in the intermediate container 91 is discharged to the drug container 15, the positions of the intermediate container 91 and the drug container 15 are exchanged again, and the drug is first weighed from the drug container 15 to the intermediate container 91. You may go from.

A configuration of a portion for inputting a driving force of the actuator 24 for opening and closing the shielding member 22 of the drug container 15, a configuration of a portion for inputting a driving force of the actuator 24 for opening and closing the shielding member 95 of the intermediate container 91, Do not have to be the same.

The opening of the drug container 15 may be formed, for example, on the side instead of the bottom. The same applies to the intermediate container 91.

The input member in the drug container 15 and the intermediate container 91 may be, for example, a drive input gear instead of the rod-shaped member. The actuator 24 can be, for example, a solenoid instead of the electric motor.

Either one of the first discharge unit 32a and the second discharge unit 32b may be omitted.
