Exemplary Embodiment of Present Disclosure

(17) Referring to FIGS. 4 to 12, a medicine cassette 100 according to one embodiment of the present disclosure is illustrated. As illustrated in the drawings, the medicine cassette 100 according to one embodiment of the present disclosure may be configured to include a medicine supplier 200 for supplying medicines, a medicine delivery part 300 for delivering the medicines supplied from the medicine supplier 200, and a medicine discharge part 400 for discharging the medicines, which are delivered from the medicine delivery part 300, to the outside (e.g., a hopper of an automatic medicine packaging apparatus) (see FIGS. 4 and 5).

(18) According to one embodiment of the present disclosure, the medicine supplier 200 performs a function of supplying medicines, which are accommodated in a medicine accommodation part 210, to the medicine delivery part 300 using a rotating rotor part (a rotating rotor 230 and a sliding member 240) installed at a base portion 220 of the medicine accommodation part 210.

(19) In particular, the medicine supplier 200 may include the medicine accommodation part 210 in which the medicines are accommodated, the base portion 220 for forming a portion of a bottom surface of the medicine accommodation part 210, and the rotating rotor part (the rotating rotor 230 and the sliding member 240) installed at the base portion 220 (see FIG. 6). In an embodiment illustrated in the drawings, a portion of the bottom surface of the medicine accommodation part 210, at which the rotating rotor part is installed, is formed of a separate member (the base portion 220) and then the separate member (the base portion 220) is mounted to the medicine accommodation part 210, in order to facilitate an installation of the rotating rotor part. However, the base portion 220 may be integrally formed with the medicine accommodation part 210.

(20) The medicine accommodation part 210 has an accommodation space therein to perform a function of accommodating the medicines in the accommodation space.

(21) The base portion 220 forms the bottom surface of one side of the medicine accommodation part 210, and the rotating rotor part is installed at an upper portion of the base portion 220 to supply the medicines, which are accommodated in the medicine accommodation part 210, to the medicine delivery part 300. The base portion 220 may be disposed in an inclined structure so as to supply the medicines, which are accommodated in the medicine accommodation part 210, to the medicine delivery part 300. A medicine supply inlet 222 may be provided at one side of the base portion 220 to supply the medicines to the medicine delivery part 300. Further, according to one embodiment of the present disclosure, a guide groove 224 may be provided at an upper portion of the base portion 220 to guide a movement of the sliding member 240 installed at the rotating rotor 230, as shown in FIGS. 6 and 10. The movement of the sliding member 240 by the guide groove 224 will be described in detail below.

(22) The rotating rotor part is installed at the upper portion of the base portion 220 to perform a function of supplying the medicines accommodated in the medicine accommodation part 210 to the medicine delivery part 300 while being rotated by a driving motor or the like.

(23) According to one embodiment of the present disclosure, the rotating rotor 230 may be formed in a structure having a substantially disc shape and having at least one recess 232 at an outer circumference of the rotating rotor 230. In the embodiment shown in the drawing, the rotating rotor 230 has four recesses 232 at an outer circumference of the rotating rotor 230 at intervals of 90 degrees. The recesses 232 provided at the rotating rotor 230 performs a function of receiving medicines accommodated in the medicine accommodation part 210 and moving the medicines toward an upper portion where the medicine supply inlet 222 is positioned.

(24) According to one embodiment of the present disclosure, the sliding member 240 may be installed at the recess 232 formed at the outer circumference of the rotating rotor 230 such that the sliding member is movable in the recess of the rotating rotor along the radial direction of the rotating rotor. As described below, the sliding member 240 is located at an inwardly entered position along the radial direction of the rotating rotor 230, and then the sliding member 240 is moved to an outer side in the radial direction of the rotating rotor 230 to perform a function of pushing the medicine inserted into the recess 232 to the medicine supply inlet 222 when the recess 232 approaches the medicine supply inlet 222 by a rotation of the rotating rotor 230. For example, when the recess 232 reaches a position corresponding to the medicine supply inlet 222 by a rotation of the rotating rotor 230, the sliding member 240 operates to close the recess 232 and push the medicine inserted into the recess 232 toward the medicine supply inlet 222, thereby smoothly providing the medicine to the medicine delivery part 300.

(25) For a radial movement of the sliding member 240 relative to the rotating rotor 230, the medicine cassette 100 according to one embodiment of the present disclosure is configured such that guide slits 234 are formed at both lateral surfaces of the recess 232 of the rotating rotor 230 (see FIG. 8), and guide protrusions 242 having a shape corresponding to the guide slits 234 are formed at both lateral surfaces of the sliding member 240 (see FIGS. 9A and 9B), and the guide protrusions 242 of the sliding member 240 are slidably moved by being inserted into the guide slits 234 formed at the recess 232 of the rotating rotor 230.

(26) Meanwhile, a surface of the sliding member 240, which is positioned at the outer circumference when the sliding member 240 is installed at the rotating rotor 230, may be formed in an inclined structure (see FIGS. 4, 7A, and 7B). That is, the outer circumference of the sliding member 240 may be configured to be inclined from a front side of a rotational direction of the rotating rotor 230 toward a rear side thereof. According to such a structure, the medicine inserted into the recess 232 of the rotating rotor 230 may be more stably kept in the recess 232, and may be smoothly transferred toward the medicine delivery part 300 when the recess 232 reaches the medicine supply inlet 222.

(27) Further, according to one embodiment of the present disclosure, a protrusion 244 vertically extending from the sliding member 240 may be provided at a rear surface of the sliding member 240. The protrusion 244 may be inserted into the guide groove 224 formed at the base portion 220 to perform a function of guiding a movement of the sliding member 240 (see FIGS. 9A, 9B, and 10).

(28) Particularly, as shown in FIG. 10, the guide groove 224 of the base portion 220 may be formed in a shape such that the distance between the guide groove 224 and a center of rotation of the rotating rotor 230 is increased as approaching the medicine supply inlet 222 along the rotational direction of the rotating rotor 230 (i.e., as being moved in Direction S shown in FIG. 10) and the distance between the guide groove 224 and the center of rotation of the rotating rotor 230 is decreased after passing a position corresponding to the medicine supply inlet 222 (i.e., as being moved in Direction T). Meanwhile, after the sliding member 240 is inwardly moved in a radial direction of the rotating rotor 230, the distance between the guide groove 224 and the center of rotation of the rotating rotor 230 is kept in constant such that the space for receiving medicine may be secured in the recess 232 of the rotating rotor 230 (see portion U shown in FIG. 10).

(29) According to such a structure of the guide groove 224, when the rotating rotor 230 is rotated on the base portion 220 by a driving motor or the like, the sliding member 240 may be moved in a state in which the protrusion 244 is inserted into the guide groove 224 of a base portion 220, and the sliding member 240 is outwardly moved in the radial direction of the rotating rotor 230 due to the shape of the sliding member 240 that the distance between the guide groove 224 and the center of rotation of the rotating rotor 230 is increased as approaching the medicine supply inlet 222, and the sliding member 240 is inwardly moved in the radial direction of the rotating rotor 230 due to the shape of the sliding member 240 that the distance between the guide groove 224 and the center of rotation of the rotating rotor 230 is gradually decreased after passing the medicine supply inlet 222. That is, when the recess 232 of the rotating rotor 230 into which the sliding member 240 is inserted approaches the medicine supply inlet 222, the sliding member 240 is outwardly moved in the radial direction of the rotating rotor 230 to outwardly push the medicine inserted in the recess 232 of the rotating rotor 230, thereby allowing the medicine to be smoothly transferred to the medicine delivery part 300. After the recess 232 of the rotating rotor 230 passes the medicine supply inlet 222, the sliding member 240 is inwardly moved in the radial direction of the rotating rotor 230 to make the recess 232 of the rotating rotor 230 as empty space so that the medicines accommodated in the medicine accommodation part 210 can be inserted into the recess 232 of the rotating rotor 230 and moved toward the medicine supply inlet 222.

(30) Referring to FIG. 11, operations of the rotating rotor 230 and the sliding member 240 are exemplarily illustrated. First, a first figure shown at an upper left portion of FIG. 11 illustrates a state that the recess denoted as a reference numeral 232a is located at the position corresponding to the medicine supply inlet 222. In such a state, when the rotating rotor 230 rotates in a counterclockwise direction (Direction R shown in FIG. 11), a sliding member 240a inserted in the recess 232a is inwardly moved in the radial direction of the rotating rotor 230 as a protrusion formed at the sliding member 240a is moved in the guide groove 224 formed at the base portion 220 according to Direction T, and a sliding member 240b inserted into a recess denoted as a reference numeral 232b is outwardly moved in the radial direction of the rotating rotor 230 as a protrusion formed at the sliding member 240b is moved in the guide groove 224 formed at the base portion 220 according to Direction S (see an upper middle diagram and an upper right diagram of FIG. 11). With such operations, the medicine inserted into the recess 232b is outwardly pushed from the recess 232b of the rotating rotor 230 by the sliding member 240b to be supplied to the medicine delivery part 300, and such a movement of the sliding member is repeatedly performed at all recesses as the rotating rotor 230 rotates. Accordingly, unlike the conventional medicine cassettes, the medicine may be smoothly discharged to the outside regardless of the shape of the medicine and a state that the medicine is inserted into the recess of the rotating rotor.

(31) Meanwhile, a point of time at which the sliding member 240 starts to be inwardly moved in the radial direction of the rotating rotor 230 is preferably determined such that the sliding members 240 starts to inwardly move when the recess 232 of the rotating rotor 230 is located at a position corresponding to the medicine supply inlet 222 or immediately after the recess 232 of the rotating rotor 230 passes the position corresponding to the medicine supply inlet 222, in order to facilitate discharge of the medicine by the sliding member 240.

(32) Further, according to one embodiment of the present disclosure, the medicine accommodation part 210 may be configured such that a space extension 215 is provided at a portion at which the recess 232 of the rotating rotor 230 is ascended toward the medicine supply inlet 222, and thus an empty space is secured at a periphery of the recess 232 which is ascended toward the medicine supply inlet 222. For example, as shown in FIG. 4, the medicine accommodation part 210 may be configured such that a wall surface of the medicine accommodation part 210 is located at a position adjacent to the recess 232 of the rotating rotor 230 which is descended toward a side opposite the medicine supply inlet 222 (i.e., toward the lower portion of the medicine accommodation part 210), whereas a wall surface of the medicine accommodation part 210 is located at a position spaced apart from the recess 232 of the rotating rotor 230 which is ascended toward the medicine supply inlet 222, and the bottom surface of the base portion 220 is formed to be downwardly stepped for securing the space extension 215 in the vicinity of the recess 232. According to such a configuration, when two or more medicines are moved while being inserted into the recess 232 of the rotating rotor 230, the medicine which is moved by being laid on an outer side of the recess 232 may be dropped again into the medicine accommodation part 210 before reaching the medicine supply inlet 222 such that it is possible to prevent a plurality of medicines from being bundled and transferred to the medicine delivery part 300.

(33) Next, the medicine delivery part 300 performs a function of arranging medicines transferred from the medicine supplier 200 in a state of being spaced away at predetermined intervals and transferring the medicines to the medicine discharge part 400 one by one. To this end, the medicine delivery part 300 may include a transfer part 310 that the medicines are disposed on an upper portion thereof, and a vibration part 320 for applying vibration to the medicine transfer part 310 (see FIGS. 4 and 5).

(34) The transfer part 310 is installed in a state of being finely declined toward the medicine discharge part 400 and performs a function of gradually transferring the medicines, which are disposed on the upper portion of the transfer part 310, toward the medicine discharge part 400 as the vibration part 320 vibrates. The transfer part 310 is preferably formed in a U-shaped or V-shaped cross-sectional structure such that the medicines can be disposed at a central portion of the transfer part 310 and smoothly moved. Further, the transfer part 310 may be formed of various materials such as a metal material, a non-metal material, a mixed material of the metal material and the non-metal material, and the like as necessary.

(35) The vibration part 320 performs a function of vibrating the transfer part 310 so as to arrange the medicines disposed on the transfer part 310 one by one and allow the medicines to be moved toward the medicine discharge part 400. The vibration part 320 may have any structure as long as it can apply vibration to the transfer part 310. Since the present disclosure is not characterized in a specific structure of the vibration part 320, a detailed description of the vibration part 320 will be omitted.

(36) Next, the medicine discharge part 400 performs a function of discharging the medicines, which are delivered by the medicine delivery part 300, to the outside (e.g., a hopper of an automatic medicine packaging apparatus). The medicine discharge part 400 may include an inlet 410 through which the medicines delivered from the medicine delivery part 300 passes, a detector (not shown) installed at the inlet 410 and configured to detect the number of the medicines delivered to the medicine discharge part, a packaging passage 420 configured to discharge the medicines to the outside (e.g., a packaging apparatus) when the number of the medicines detected through the detector matches prescription information, and a recollecting passage 430 configured to transfer the medicines to a recollecting container when the number of the medicines detected through the detector does not match the prescription information.

(37) According to one embodiment of the present disclosure, a retention member 440 may be provided at the medicine discharge part 400 to temporarily retain the medicines introduced through the inlet 410 at which the detector is provided, and an opening and closing member 450 may be provided at a lower portion of the retention member 440 to selectively open one of the packaging passage 420 and the recollecting passage 430 according to the detected result of the detector (see FIG. 12). The retention member 440 and the opening and closing member 450 may be installed to be pivotable in a certain angle range through a driving motor or the like.

(38) FIG. 12 exemplarily illustrates a structure of the medicine discharge part 400 of the medicine cassette according to one embodiment of the present disclosure. In FIG. 12, the state in which the retention member 440 is pivoted in a clockwise direction such that medicines can be downwardly supplied and, at the same time, the opening and closing member 450 is pivoted in a clockwise direction to open the packaging passage 420 and close the recollecting passage 430 is illustrated as a solid line.

(39) In this state, when the retention member 440 is rotated in a counterclockwise direction to close the inlet 410 as illustrated as a dotted line in FIG. 12, the medicines introduced into the medicine discharge part 400 may be retained on the retention member 440. Further, when the opening and closing member 450 is rotated in a counterclockwise direction as illustrated as a dotted line in FIG. 12, the packaging passage 420 may be closed and the recollecting passage 430 may be opened.

(40) The above-described medicine discharge part 400 of the medicine cassette according to one embodiment of the present disclosure may operate as follows.

(41) First, the number of medicines delivered to the medicine discharge part 400 is detected while passing through the detector installed at the inlet 410. At this point, the retention member 440 installed in the vicinity of the inlet 410 is rotated and located at a position capable of closing the inlet 410 to retain the medicines, which are being dropped, on the retention member 440.

(42) When the number of the medicines dropped on the retention member 440 matches prescription information (i.e., the number of medicines which will be packaged in a single medicine pouch), the opening and closing member 450 is pivoted to a position capable of opening the packaging passage 420 and closing the recollecting passage 430. Then, when the retention member 440 is pivoted to open the inlet 410, the medicines temporarily retained on the retention member 440 may be downwardly dropped and supplied to the packaging passage 420, and the medicines supplied to the packaging passage 420 may be packaged by being fed to a packaging apparatus through a hopper of an automatic medicine packaging apparatus.

(43) In contrast, when the number of the medicines dropped on the retention member 440 do not match the prescription information (i.e., the number of medicines which will be packed in a single medicine pouch), the opening and closing member 450 is pivoted to a position capable of opening the recollecting passage 430 and closing the packaging passage 420. Then, when the retention member 440 is pivoted to open the inlet 410, the medicines temporarily retained on the retention member 440 are downwardly dropped and supplied to the recollecting passage 430. The medicines supplied to the recollecting passage 430 are supplied to the recollecting container, and the medicines collected in the recollecting container may be reused later.

(44) Meanwhile, the above-described medicine cassette according to one embodiment of the present disclosure may be installed at an automatic medicine packaging apparatus together with the conventional medicine cassette or instead thereof for supplying medicines. When the medicine cassette according to one embodiment of the present disclosure is installed and used in the automatic medicine packaging apparatus, medicines are automatically supplied to the packaging apparatus by a required number of the medicines according to a packaging cycle in which the medicines are discharged and packaged.

(45) While the present disclosure has been described with reference to specific items such as particular components, exemplary embodiments, and drawings, these are merely provided to help understanding the present disclosure, and the present disclosure is not limited to these embodiments, and those skilled in the art to which the present disclosure pertains can variously alter and modify from the description of the present disclosure.

(46) Therefore, the spirit of the present disclosure should not be limited to the above-described embodiments, and it should be construed that the appended claims as well as all equivalents or equivalent modifications of the appended claims will fall within the scope of the present disclosure.
