According to one embodiment, the remaining chemical liquid monitoring unit 503 is located in a designated area, and as the piston packing unit 501b is lowered downward in the internal space by the lowering start unit 501, the internal It is possible to photograph whether the external air supplied to the space discharges the remaining chemical solution 501e located in the discharge pipe 501d to a plurality of medicine containers.

In more detail, when the piston packing part 501b descends downward in the inner space, the air located in the inner space is opened by the downward pressing force by the piston packing part 601b. It can be discharged toward 501d. Accordingly, the remaining chemical liquid 501e in the discharge pipe 501d can be discharged to the outside by the moving force of the air discharged to the outside.

In relation to the above, the remaining chemical solution monitoring unit 503 is installed in one area of the designated area and may be a photographing means for checking whether the remaining chemical solution 501e is discharged from the discharge pipe 501d. When obtaining an image in which the remaining chemical solution 501e is discharged from the discharge pipe 501d, the remaining chemical solution monitoring unit 503 identifies an object corresponding to the remaining chemical solution 501e in the image, It can be confirmed that the remaining chemical liquid 501e is discharged from the discharge pipe 501d.

According to an embodiment, the chemical liquid discharge completion unit 505 confirms that the residual liquid liquid 501e located in the discharge pipe 501d is discharged into at least one of a plurality of medicine cabinets through the residual liquid liquid monitoring unit 503. In this case, the remaining chemical capacity checking unit (eg, the remaining chemical capacity checking unit 404 of FIG. 4 ) calculates the discharge capacity of the chemical liquid discharged from the chemical liquid tank 501a, and calculates the discharge capacity of the chemical liquid discharged from the chemical liquid tank 501a. In step 501, it may be requested to check whether a difference value obtained by comparing storage capacities before the chemical solution is discharged exceeds a specified reference value.

In more detail, the discharge information receiving unit 401 to check the discharge capacity of the remaining chemical solution 501e discharged from the chemical solution tank 501a when the request is received from the chemical solution discharge completion unit 505 by the remaining chemical solution capacity confirmation unit. Based on the discharge capacity information received through ), the discharge capacity of the remaining chemical solution 501e discharged from the chemical solution tank 501a may be calculated. The remaining chemical capacity check unit adds up the calculated discharge capacity of the remaining chemical liquid 501e and the previously calculated discharge capacity of the discharged chemical liquid (eg, the chemical liquid discharged in FIG. A difference value may be obtained by comparing storage capacities of the chemical solution before being discharged from the chemical solution tank 501a.

At this time, the remaining chemical solution capacity confirmation unit checks whether the obtained difference value exceeds a specified reference value, and if it is confirmed that the difference value does not exceed a specified reference value, the chemical solution discharge completion unit 505 Information corresponding to the confirmation result may be transmitted.

Accordingly, the chemical solution discharge completion unit 505 determines that all of the remaining chemical liquid 501e in the discharge pipe 501d has been discharged through the information corresponding to the confirmation result received from the remaining chemical liquid capacity confirmation unit, and conveys By controlling the four-belt, multiple medicine cabinets located within a designated area can be moved to the packaging area. The packaging area may be an area in which facilities for packaging a plurality of medicine containers are installed among areas included in facilities including the liquid medicine pressurizing device.
