This application claims priority to and the benefit of Korean Patent Application No. 10-2017-0124552, filed on Sep. 26, 2017, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to a medicine cassette configured to automatically discharge medicines according to prescription information and an automatic medicine packaging apparatus including the medicine cassette, and more particularly, to a medicine cassette configured to automatically discharge shaped medicines as well as shapeless medicines such as half-tablets and the like according to prescription information and an automatic medicine packaging apparatus including the medicine cassette.
There has been developed and used an automatic medicine packaging apparatus which receives medicines from a plurality of cassette devices, in which the medicines such as tablets and capsules are accommodated according to types thereof, and continuously packages a dose of medicines.
As shown in
Meanwhile, the medicine cassettes 20 provided at the automatic medicine packaging apparatus includes a cassette main body configured to accommodate medicines of various sizes and shapes, a distribution block rotatably provided at the cassette main body and configured to discharge the medicines, and a partition member installed at the cassette main body and configured to discharge the medicines, which are discharged from the distribution block, at a predetermined amount, and thus discharges the medicines, which are accommodated in a cassette device through a discharge recess formed in the distribution block to the outside.
However, the medicine cassette provided at a conventional automatic medicine packaging apparatus is generally configured to discharge only medicines having a predetermined shape and size corresponding to a discharge recess formed at a distribution block, and thus when a variant medicine of which form is shapeless (e.g., a half-tablet obtained by halving a medicine, etc.) is included in the medicine cassette, there is a problem in that medicines cannot be automatically discharged according to a prescription information.
In order to resolve such a problem, a medicine cassette capable of being configured to discharge variant medicines such as half-tablets and the like has recently emerged. For example, Korean Patent No. 10-0729477 (Prior Art 1) discloses a medicine cassette (a tablet feeder) configured to automatically supply half-tablets.
As shown in
However, such a medicine cassette has a problem that it is difficult to smoothly discharge half-tablet medicines since the medicine cassette is configured to discharge only half-tablet medicines having a shape and a size, which correspond to those of the notch portion 75 formed at the rotor 70, and discharge half-tablet medicines only in a state of being arranged in the notch portion 75 in a correct direction. Particularly, the above-described conventional medicine cassette is configured such that half-tablet medicines can be discharged to the outside through gravity only when the half-tablet medicine is inserted into the notch portion 75 in a state that a bottom surface of the half-tablet medicine is brought into contact with the bottom surface of the supplier vessel 60 as a medicine indicated by a reference numeral “a” in

Referring to
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.
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
The medicine accommodation part 210 has an accommodation space therein to perform a function of accommodating the medicines in the accommodation space.
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
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.
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.
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.
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
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
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
Particularly, as shown in
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.
Referring to
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.
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
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
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.
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.
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.
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
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
The above-described medicine discharge part 400 of the medicine cassette according to one embodiment of the present disclosure may operate as follows.
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.
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.
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.
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.
