Further, inside the container body 8, the main housing portion 7 and the semi-cylindrical portion 16 communicate with each other to constitute one medicine storage portion 52.

Next, the main body side device 3 will be described.

As shown in FIG. 9, the main body side device 3 includes a mounting table 60, a weight measuring device 61, and a base member 64 from top to bottom.

Hereinafter, the description will be sequentially made.

The mounting table 60 is a table on which the drug container 2 is placed, and its surface is formed in a shape that matches the shape of the lower cover 6 of the drug container 2. In other words, the surface of the mounting table 60 has a mounting top surface 70 that abuts against the bottom surface of the lower cover 6, and mounting inclined side surfaces 71a and 71b that match the inclined side walls 48a and 48b of the lower cover 6. Further, the mounting table 60 has a vertical surface 72 that abuts against the inner side wall 50 of the lower cover 6.

An electromagnet 62 and a driving side member 63 are provided inside the mounting table 60. Further, a motor 65 is attached to the mounting table 60. electric motor 65 is a component that functions as a drive source.

That is, the magnet mounting hole 66 is provided on the mounting top surface 70 of the mounting table 60, and the electromagnet 62 is incorporated in the magnet mounting hole 66.

Further, a drive member accommodating portion 75 is provided at a position parallel to the magnet attachment hole 66, and a drive side member 63 is incorporated in the drive member accommodating portion 75. The drive member accommodating portion 75 is provided in a cavity below the placement top surface 70, and the drive side member 63 is not exposed to the placement top surface 70 because it is built in the drive member accommodating portion 75. The reason why the driving side member 63 is not exposed is that it is recommended to prevent the powder present in the air from adhering to or from the driving side member 63. However, as long as effective measures can be taken to prevent the adhesion of the powder, The drive side member 63 can be exposed from the placement top surface 70.

The drive side member 63 is a cylindrical magnet.

The motor 65 is an ordinary small-sized DC motor, and is mounted below the mounting table 60 in a state where the output shaft 76 is directly connected to the driving side member 63 as shown in FIG. 3, and a part of the motor 65 is as shown in FIG. 2. It is exposed from the mounting table 60 as shown in FIG.

When the motor 65 rotates, the drive side member 63 rotates in the drive member housing portion 75.

The weight measuring means 61 is a conventional force measuring sensor having an upper setting surface 78 and a lower setting surface 80, and the upper setting surface 78 and the lower setting surface 80 are located at a relative offset.

The base unit 64 has " The table portion 81 and the table of the flange portions 82a, 82b. However, the base member 64 is only a jig for mounting the body side device 3 of the drug feeder 1 with respect to other members, so the shape in the embodiment is not correct. Its implementation is limited.

In the main body side device 3 of the present embodiment, the weight measuring means 61 is disposed below the mounting table 60, and the base member 64 is disposed below the weight measuring means 61.

The upper installation surface 78 of the weight measuring means 61 is connected to the bottom surface of the mounting table 60, and the lower installation surface 80 of the weight measuring means 61 is attached to the base member 64.

As described above, since the upper setting surface 78 and the lower setting surface 80 are located at relatively offset positions, the intermediate portion of the weight measuring means 61 is supported on one side with respect to the base member 64, and is free from the free end of the weight measuring means 61. The side supports the mounting table 60.

In the present embodiment, the member connected between the mounting table 60 and the base member 64 has no other members than the weight measuring means 61 described above. Therefore, the mounting table 60 is formed to be suspended by the base member 64 by the weight measuring means 61.

Therefore, in the present embodiment, when the drug container 2 is placed on the mounting table 60, the weight of the drug container 2 is indirectly measured. That is, since the weight of the mounting table 60 and the drug container 2 is detected by the weight measuring means 61, the weight of the known mounting table 60 is subtracted, and the weight of the drug container 2 is measured.

The drug dispenser 1 of the present embodiment is constituted by the drug container 2 and the main body side device 3 as described above, but in general, the drug container 2 and the main body side device 3 are separate components, and when the powder is packaged, The drug container 1 is combined with the main body side device 3 to constitute the drug feeder 1.

That is, the main body side device 3 of the drug dispenser 1 is fixed to the vicinity of the distribution tray 112 of the medicine dispensing device 100 as shown in Figs. 10 and 11 .

On the other hand, the drug container 2 is placed and stored in the drug container housing frame 101 shown in FIG. That is, after the drug container 2 is filled with a predetermined powder, the drug container 2 is placed in the drug container housing frame 101 in a horizontally placed posture, for example, as shown in FIG.

Next, the external device of the drug feeder 1 will be described.

The drug dispenser 1 of the present embodiment is a device that constitutes a part of the medicine dispensing device 100 having a powder dispensing function.

The overall structure of the medicine dispensing device 100 is, for example, the structure shown in FIG. From the functional point of view, the medicine dispensing device 100 is divided into a medicine rack portion region 103, a medicine divided region 105, and a medicine packaging region 106 in the vertical direction.

The medicine rack holding frame 101 is arranged around the medicine rack portion 103 located at the uppermost portion, and the medicine container moving device 102 is provided inside.

The drug container moving device 102 is a robot, and has a vertical lifting shaft 107, a horizontal moving arm 108, and a hand 110 that holds the drug container 2.

A powder dispensing device 111 is provided in the drug dividing region 105. In the present embodiment, the powder dispensing device 111 is provided with two dispensing trays 112. A plurality of the drug feeders 1 of the present embodiment are provided in the powder dispensing device 111. In the present embodiment, three drug feeders 1 are provided for each of the distribution trays 112.

Further, a drug packaging device 120 is built in the drug packaging region 106.

Further, the medicine dispensing device 100 includes a prescription reading means 121 for reading a prescription and a control means 122 for controlling the operation of each apparatus.

The control device 122 stores data for managing the type and number of drugs stored in the medicine dispensing device 100. In other words, in the medicine dispensing device 100, data indicating which medicine is contained in which medicine container 2 is stored in all the medicine containers 2 . Moreover, the data is rewritten and updated, so that the amount of which medicine is currently contained is managed.

Further, a display device 123 is provided in the medicine dispensing device 100.

When the required medicine is insufficient or an abnormality occurs in the apparatus, a predetermined display is performed on the display device 123.

Next, the function of the drug feeder 1 of the present embodiment will be described. Further, since the drug feeder 1 is a device constituting one of the drug dispensing devices 100, the operation of the drug feeder 1 will be described, including the operation of the entire powder dispensing device.

In the present embodiment, when the content of the prescription is read by the prescription reading means 121 of the medicine dispensing device 100, all the operations are started.

That is, when the content of the prescription is input, the medication capacity is started immediately. The carry-out operation of the device 2. More specifically, the drug container moving device 102 is driven, and the drug container 2 containing the drug matching the prescription is selected from the plurality of drug containers 2 disposed in the drug rack portion region 103, and the selected drug container 2 is selected. It is placed on the main body side device 3 of the drug feeder 1.

In the present embodiment, as described above, the drug container 2 and the main body side device 3 are separate members, and when the powder is divided, the drug container 2 and the main body side device 3 are combined to constitute the drug feeder 1.

In other words, in the present embodiment, the drug container 2 in which the powder is stored is stored in the drug container housing 101 in the horizontally placed posture.

In the present embodiment, the drug container 2 is grasped by the drug container moving device 102 and the drug container 2 is moved, and the drug container 2 is placed on the mounting table 60 of the main body side device 3 as shown in Figs. 1 and 2 . .

Then, the electromagnet 62 built in the mounting table 60 is energized. Thereby, a magnetic force is generated in the electromagnet 62, and the magnetic body plate 25 of the drug container 2 is adsorbed on the adsorption surface of the electromagnet 62 on the mounting table 60 side.

Here, in the present embodiment, the lower cover 6 of the drug container 2 is provided with an opening 51 from which the magnetic plate 25 is exposed. Therefore, the electromagnet 62 can be electromagnetically adsorbed by being in direct contact with the magnetic body plate 25, and the drug container 2 can be strongly fixed to the mounting table 60.

In this state, the follower member 13 of the drug container 2 is located directly above the drive member housing portion 75 of the mounting table 60. However, since the bottom wall 47 of the lower cover 6 serves as a partition between the driving side member 63 and the driven member 13, the driving side member 63 does not directly contact the driven member 13.

Then, the motor 65 mounted on the mounting table 60 is rotated. Here, since the output shaft 76 of the motor 65 is directly connected to the driving side member 63, the driving side member 63 in the driving member housing portion 75 is rotated by the starter motor 65.

Here, the driving side member 63 is a cylindrical magnet, and the driven member 13 of the drug container 2 is located at a position in the vicinity of the driving side member 63. Further, the driven member 13 is also a cylindrical magnet. Therefore, the driven member 13 is attracted to the driving side member 63 by the magnetic force of the driving side member 63, and rotates together with the driving side member 63.

That is, the driven member 13 is located in the driven member accommodating space 22 surrounded by the lower cover 6, and is in a non-contact state with the driving side member 63. Further, a bottom wall 47 of the lower cover 6 exists between the driven member 13 and the driving side member 63. In this manner, the driven member 13 does not contact the driving side member 63, and the bottom wall 47 is present therebetween. However, the magnetic lines of force of the driving side member 63 penetrate the bottom wall 47 to apply a magnetic force to the driven member 13, thereby making the driven member 13 rotation.

Thereby, the spiral member 12 connected to the driven member 13 rotates in the semi-cylindrical portion 16 in the container body 8.

Here, the spiral member 12 is a screw, and blades 27a, 27b, and 27c are provided around the rotating shaft 26.

Further, a spacer is not present between the main housing portion 7 and the semi-cylindrical portion 16, and the main housing portion 7 and the semi-cylindrical portion 16 communicate with each other to constitute one medicine storage portion 52.

Therefore, the powder that has entered the main housing portion 7 enters the semi-cylindrical shape portion 16. Here, the semi-cylindrical shape portion 16 is located at the bottom of the drug storage portion 52, and the cross-sectional shape of the container body 8 is substantially as shown in FIG. It is pentagonal and inclined to a state where the bottom side is narrowed. Further, the back side surface 14 of the container body 8 is formed as an inclined surface 18. Therefore, the inside of the container body 8 has a shape that is contracted toward the semi-cylindrical portion 16 as a whole, and is formed so that the powder in the drug storage portion 52 is easily collected in the semi-cylindrical portion 16 in a concentrated manner.

Therefore, the powder of the medicine accommodating portion 52 is concentrated in the semi-cylindrical portion 16, and is pushed by the blades 27a, 27b, and 27c by the rotation of the spiral member 12, and is advanced toward the medicine discharge portion 24. Then, the powder is finally discharged to the outside from the medicine discharge portion 24 of the discharge port forming member 11.

Further, in the present embodiment, the blade 27 of the spiral member 12 is present along the entire length of the bottom portion of the drug storage portion 52, and the region in which the blade 27 is provided is longer than the region disclosed in Patent Document 2.

Therefore, the distance at which the medicine is pushed and moved is long. Therefore, while the medicine is pushed by the blade 27 to move, the new powder enters the gap between the blades 27, and the powder is densely piled up between the blades 27 as it proceeds toward the discharge port forming member 11 side. Further, since the interval between the blades 27 on the front end side of the spiral member 12 is narrower than the interval between the blades 27 on the rear end side, the powder is densely packed as it advances toward the discharge port forming member 11 side. Between the blades 27.

Therefore, in the present embodiment, the amount of the medicine discharged from the discharge port forming member 11 is stable.

Further, in the present embodiment, since the blade 27 is provided in three rows, a fixed amount of the powder is discharged from the discharge port forming member 11 per unit time.

That is, the powder is discharged when the medicament reaches the end of the blade 27. However, depending on the rotational posture of the tip end of the blade 27, the amount of the drug discharged from the end of the blade 27 is different. Here, in the present embodiment, the blades 27 are provided in a plurality of rows and the ends of the respective blades are located at the front end of the spiral member 12. Therefore, the variation in the discharge amount of the medicine due to the difference in the rotational posture of the blade tip is canceled, and the amount of the medicine discharged from the discharge port forming member 11 is stabilized.

Further, in the present embodiment, the broken portions 28 are provided at regular intervals on the blades 27a, 27b, and 27c of the respective systems. Therefore, even if a medicine block occurs in the powder during the rotation of the spiral member 12, the medicine piece is pulverized by the broken portion 28. Therefore, the powder in a loose state is discharged from the discharge port forming member 11.

In addition, the dispensing tray 112 of the powder dispensing device 111 is rotated immediately before or after the start of the motor 65.

The weight of the drug container 2 is measured before or after the starter motor 65. The weight of the drug container 2 is the weight obtained by subtracting the fixed value from the detected weight detected by the weight measuring means 61. More specifically, the weight of the drug container 2 is the weight obtained by subtracting the weight of the component located above the weight measuring means 61 in the main body side device 3 from the detected weight detected by the weight measuring means 61.

That is, the entire weight of the member located above the weight measuring means 61 is measured by the weight measuring means 61.

Therefore, in the state in which the drug container 2 is placed on the mounting table 60, the weight measuring means 61 detects the value obtained by adding the weight of the drug container 2 to the weight of the mounting table 60 or the like.
