The operation of the drug supply device 10 according to an embodiment of the present invention will be described below. First, the operation of the medicine supply module 100, which is a medicine supply section, will be explained.

The medicine supplied from the medicine supply hole 127 to the inside of the lid member 120 is located on the slope 110s and supported by the first peripheral wall part 121. The first motor 270 drives each of the first rotating section 111 and the second rotating section 112.

By driving the first rotating section 111, the drug supported by the first peripheral wall section 121 is conveyed along the first peripheral wall section 121. The medicine supported by the first peripheral wall 121 is aligned along the first peripheral wall 121 while being conveyed along the first peripheral wall 121 .

The medicine supported by the first peripheral wall part 121 is moved outward in the radial direction while descending along the first inclined wall part 124, starting from the medicine located on the leading side in the rotational direction 2. It is supported by the peripheral wall portion 122.

The medicine descending along the first inclined wall 124 is accelerated by gravity, and therefore moves at a higher speed than the medicine being conveyed along the first inclined wall 124. Thereby, the distance between the drug that has descended along the first inclined wall portion 124 and the drug that has not descended along the first inclined wall portion 124 becomes wider.

By driving the first rotating part 111, the drug supported by the second peripheral wall part 122 is conveyed along the second peripheral wall part 122. The medicine supported by the second peripheral wall part 122 is moved outward in the radial direction while descending along the second inclined wall part 125, starting from the medicine located on the leading side in the rotational direction 2. It is supported by the peripheral wall portion 123.

The drug descending along the second inclined wall 125 is accelerated by gravity, and therefore moves at a higher speed than the drug being conveyed along the second inclined wall 125. Thereby, the distance between the drug that has descended along the second inclined wall portion 125 and the drug that has not descended along the second inclined wall portion 125 becomes wider.

By driving the second rotating section 112, the drug supported by the third peripheral wall section 123 is conveyed along the third peripheral wall section 123. Since the rotational speed of the second rotating section 112 is higher than the rotational speed of the first rotating section 111, the distance between the medicine supported by the third peripheral wall part 123 and the medicine supported by the second peripheral wall part 122 is small. It becomes wider.

The medicines supported by the third peripheral wall part 123 are supported by the standing wall part 132 in order from the medicine located on the leading side in the rotation direction 2. By driving the second rotating section 112, the medicine supported by the standing wall section 132 is conveyed along the standing wall section 132.

In a state where the medicine stopping part 142 is close to the slope 110s, the medicine conveyed along the vertical wall part 132 is prevented from moving to the discharge part 131. Therefore, the second motor 271 rotates the rotation shaft 140s.

By rotating the rotating shaft 140s in one direction, the opening/closing member 140 rotates around the rotating shaft 140s, the discharge section 131 that was blocked by the opening/closing section 141 is opened, and the drug retaining section 142 is opened. Separate from the slope 110s. As a result, among the medicines supported by the standing wall part 132, the medicines located on the leading side in the rotational direction 2 are discharged one by one from the discharge part 131.

At this time, the first sensor 231 detects that the medicine on the slope 110s is discharged from the discharge section 131. The second sensor 232 detects the medicine discharged from the discharge section 131.

After the medicine is discharged from the discharge part 131, the rotation shaft 140s is rotated in the other direction, so that the opening/closing member 140 is rotated around the rotation shaft 140s, and the discharge part 131 is closed by the opening/closing part 141. , the drug stopper 142 approaches the slope 110s.

As a result, the medicine supported by the standing wall part 132 is prevented from moving to the discharge part 131 by the medicine stopping part 142, and is prevented from being discharged from the discharge part 131 by the opening/closing part 141. As described above, the opening/closing section 141 is in the open state when the drug is supplied from the drug supply section, and is in the closed state when the drug is not supplied from the drug supply section.

Note that when the medicine is discharged from the discharge section 131 in the medicine supply device 10, the vibrating section 260 is temporarily stopped, the rotating body 110 is temporarily reversed, and then the medicine is discharged from the discharge section 131. The medicine may be held on the slope 110s. In this case, it is possible to prevent a plurality of medicines from being discharged from the discharge section 131 at the same time.

Alternatively, when the medicine is discharged from the discharge section 131 in the medicine supply device 10, the vibrating section 260 is temporarily stopped, the rotating body 110 is temporarily stopped, and the medicine is then discharged from the discharge section 131. The medicine may be held on the slope 110s. Even in this case, it is possible to prevent a plurality of medicines from being discharged from the discharge section 131 at the same time.

Further, when the medicine supply section moves relative to the housing 410, the medicine supply section stops and the opening/closing section 141 enters the closed state, and then the medicine supply section starts moving. In this case, it is possible to prevent undesired medicine from being discharged from the discharge part 131 while the medicine supply part is moving.

When restarting the supply of medicine from the medicine supply section, the opening/closing section 141 is brought into an open state and the medicine supply section is restarted. In this case, the medicine can be discharged from the discharge section 131 immediately after the medicine supply section restarts.

Next, the operation of the medicine container 300 attached to the base portion 200 will be explained.

The third motor 272 rotates the pair of rollers 281, thereby rotating the medicine container 300 around the axis 3.

By rotationally driving the drug storage container 300 around the axis 3, the drug in the drug storage container 300 is conveyed from the bottom 330 side of the drug storage container 300 to the first opening 313 side by the spiral groove 312, and the drug is transferred to the first opening 313 side of the drug storage container 300. It is discharged from the section 313.

The medicine discharged from the first opening 313 passes through the connecting conduit 290 of the base part 200 and is supplied into the medicine supply hole 127 of the lid member 120. The medicines supplied into the medicine supply holes 127 of the lid member 120 are discharged one by one from the discharge part 131 of the medicine supply module 100.

Note that one drug storage container 300 sequentially selected from among the plurality of drug storage containers 300 is attached to the base portion 200 . Each of the plurality of drug storage containers 300 is driven under mutually different driving conditions set based on the identifier 331. The drug supply unit is driven in correspondence with each of the plurality of drug storage containers 300.

Specifically, the types of drugs include general drugs that are small tablets, and special drugs such as capsules, elongated tablets, spherical tablets, or triangular prism-shaped tablets. Each of the plurality of drug storage containers 300 contains a general drug or a special drug. When the drug storage container 300 is attached to the base portion 200 , the control portion 41 to which the detection signal of the identifier 331 from the identification sensor 234 is input through the connection portion 11 controls the inside of the drug storage container 300 attached to the base portion 200 . Determine the type of drug contained in the container.

If the medicine stored inside the medicine storage container 300 is determined to be a general medicine, the amount of the general medicine discharged to the medicine supply unit per rotation of the medicine storage container 300 is large; Immediately after the drug replenishment sensor 235 detects the replenishment of the drug from the drug container 300 to the drug supply section, the control section 41 stops the rotation of the drug container 300 . Thereafter, when the drug is no longer detected by the drug replenishment sensor 235, the rotational drive of the drug storage container 300 is restarted. This can prevent oversupply of medicine to the medicine supply section.

When the medicine stored inside the medicine storage container 300 is determined to be a special medicine, the amount of the special medicine discharged to the medicine supply unit for each rotation amount of the medicine storage container 300 tends to be smaller. Therefore, the control unit 41 adjusts the time from when the drug replenishment sensor 235 detects the replenishment of the drug from the drug container 300 to the drug supply unit to when the rotational drive of the drug container 300 is stopped to be the same as that of a typical drug. Make it longer compared to the case. Alternatively, the control unit 41 increases the rotational speed of the drug storage container 300 compared to the case of a general drug. Furthermore, the control unit 41 also increases the rotational speed of the rotating body 110 compared to the case of general medicines. By doing so, even in the case of a special drug that is difficult to discharge by rotational driving, the time required for replenishing the drug can be brought closer to that of a general drug, and the drugs can be supplied one by one from the discharge section 131.
