BEST MODE

Mode for Invention

(4) Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

(5) As illustrated in FIG. 1, according to the preferred embodiment of the present invention, a supply apparatus 1 for drug packaging is an apparatus for supplying drug units M to drug packaging members P. The supply apparatus includes a supply unit 10, a support unit 20, a vibration unit 30, and a detection unit 40.

(6) The supply unit 10 provides a supply path along which the drug units M are conveyed and supplied to the drug packaging members. Although the supply unit 10 is not illustrated in detail, the supply unit 10 is connected to a storage unit (not shown) in which the drug units M are stored at an inlet side thereof and to the drug packaging member P at an outlet side thereof. Thus, the drug units M discharged from the storage unit (not shown) are supplied to the drug packaging members P.

(7) At this point, the inlet of the supply unit 10 is provided with an introduction hole 11 through which the drug units M are introduced into the supply unit 10, and the outlet of the supply unit is provided with a shutter 12 that can open and close a discharge hole in the outlet. The shutter 12 blocks the discharge hole so that the drug units M cannot be supplied to the drug packaging members P as necessary. That is, when there is trouble such as a supply error of the drug units M or a preparation error of the drug packaging member P, the discharge hole of the supply unit 10 is closed by the shutter 12. For reference, the shutter 12 is driven by a shutter driver 13.

(8) As shown in FIG. 2, the supply unit 10 has a pipe shape with an open upper end and a U-shaped cross section. Due to the U-shaped cross section of the supply unit 10, there is little friction between the drug units M and the inside surface of the supply unit. Therefore, the drug units M can easily pass through the supply unit 10, and the drug units M are rarely damaged by friction while passing through the supply unit 10.

(9) For reference, although the supply unit 10 has a straight pipe shape such that the drug units M are guided in one direction in the present embodiment, but the supply unit 10 is not limited to the present embodiment. That is, the supply unit 10 may be an L-shaped pipe such that the drug supply direction is not linear but changes. The shape of the supply unit 10 may diversely vary according to conditions in which the drug units M are supplied to drug packaging members.

(10) The support unit 20 elastically supports the supply unit 10 such that the supply unit 10 is inclined. The support unit 20 supports the supply unit 10 such that the supply unit 10 is inclined to slope down from the inlet to the outlet thereof, i.e. in a drug supply direction.

(11) Meanwhile, as shown in FIG. 2, the support unit 20 includes a spring hinge that elastically supports the inlet of the supply unit 10. That is, the support unit 20 elastically supports the inlet of the support unit 20. Due to the support unit 20 including the spring hinge, even though a heavy drug unit M is introduced through the inlet of the supply unit 10, the inlet of the supply unit 20 can be maintained not to be lowered because of being elastically supported.

(12) The vibration unit 30 vibrates the supply unit 10. The vibration unit 30 includes a vibrator installed near the inlet of the supply unit 10 and generates vibration of the supply unit 10. Since the vibration unit 30 vibrates the supply unit 10, the drug units M are not likely to stay near the inlet in the supply unit 10 but to easily move toward the outlet of the supply unit 10.

(13) Both of the vibration unit 30 and the support unit 20 are disposed near the inlet of the supply unit 10. The spring hinge of the support unit 20 elastically supports the inlet of the supply unit 10. Therefore, the deformation of the supply unit 20 increases from the inlet to the outlet due to the vibration caused by the vibration unit 30. In addition, as described above, the support unit 20 supports the supply unit inclined such that the outlet is lower than the inlet, i.e. sloped down in a direction in which drug units are supplied.

(14) Therefore, even in a case where drug units M introduced into the inlet of the supply unit 10 are stacked or jammed, since the amplitude of the vibration increases toward the outlet of the supply unit, the drug units become separated from each other as they approach the outlet of the supply unit and thus the drug units are sequentially conveyed. Therefore, the drug units can be sequentially discharged unit by unit out of the supply unit.

(15) The detection unit 40 detects the drug units M passing through the supply unit 10. As illustrated in FIGS. 2 and 3, the detection unit 40 includes a first sensor 41, a second sensor 42, and a third sensor 43, and detects the drug units M in the supply unit 10.

(16) The first sensor 41 is installed near the inlet of the supply unit 10 in a drug supply direction S in which the drug units M are supplied to the drug packaging member, and detects the drug unit introduced into the supply unit 10. The second sensor 42 is installed near the outlet of the supply unit 10 in the drug supply direction S and detects the drug unit discharged out of the supply unit 10. The at least one third sensor 43 is installed between the first sensor 41 and the second sensor 42 to detect the drug unit M passing through the supply unit 10.

(17) The shutter 12 installed at the outlet of the supply unit 10 is operated in accordance with detection information detected by the first to third sensors 41, 42, and 43. Specifically, when at least one sensor of the first to third sensors 41, 42, and 43 detects a supply error of the drug units M passing through supply unit 10, the shutter 12 closes the discharge hole of the supply unit 10.

(18) According to the present embodiment, each of the first to third sensors 41, 42, and 43 installed in the supply unit 10 consists of one sensor, but the present invention is not limited thereto. That is, each of the first to third sensors 41, 42, and 43 may include a pair of sensors arranged to face each other or a plurality of sensors arranged in a circumferential direction of the supply unit 10. Configuration of each sensor of the first to third sensors may be diversely altered. Meanwhile, a modification in which the third sensor 43 includes a plurality of sensors arranged side by side in the drug supply direction S is also possible.

(19) A drug supply method performed by the supply apparatus 1 for drug packaging, according to the present invention, will be described below with reference to FIGS. 1 to 3.

(20) As illustrated in FIG. 1, when a drug unit M is introduced into the inlet of the supply unit 10, which is elastically supported by the support unit 20, the first sensor 41 of the detection unit 40 detects the drug unit M. The drug unit M introduced into the supply unit 10 moves in the drug supply direction S by means of an inclined structure of the supply unit that is inclined at a predetermined inclination angle and vibration caused by the vibration unit 30, passes the third sensor 43 in a middle portion of the supply unit 20, and continuously moves toward the outlet of the supply unit 10. The drug unit M that reaches the outlet of the supply unit 10 is discharged out of the supply unit 10 when the shutter 12 is open. At this point, a drug supply error can be detected by the second sensor 42 installed near the outlet of the supply unit 10.

(21) Although a preferred embodiment of the present invention has been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
