No.
10-2013-0054607, filed on May 14, 2013, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated
herein by reference for all purposes.
BACKGROUND
1. Field
[0002] The following description relates to a pill cartridge for a medication packaging
apparatus, and more specifically, to a pill cartridge with a stopper whose height
can be freely adjusted to the shape of a pill and be installed therein.
2. Description of the Related Art
[0003] In order to solve a well-known problem of pharmacists manually packaging pills, a
medication packaging apparatus is provided. In general, the medication packaging apparatus
has multiple pill cartridges, which are arranged in multiple layers at an upper portion
to contain various types of pills. The pills contained in the pill cartridges may
be selectively discharged under the user's control by use of a computer interfaced
with the pill cartridges, and the pills discharged from the pill cartridges are collected
in a hopper, and then packaged in a packaging unit located in a lower portion of the
medication packaging apparatus.
[0004] The pill cartridge has an opening for dispensing pills at a lower portion of a case,
and a cylindrical rotor above the dispensing opening with a plurality of "guide-teeth"
and pill insertion grooves along its circumference. The rotor is connected to a rotator
placed under the dispensing opening. The rotor rotates along with the rotator, which
is rotated by a rotation motor.
[0005] A large number of pills are contained in the case of the pill cartridge, and a single
pill or a predetermined number of pills are stored in each pill insertion groove between
the guide-teeth of the rotor disposed below the case. In this state, as the rotor
rotates, the pill insertion grooves change positions, and each is sequentially brought
into line with the dispensing opening, such that the pills in the pill insertion grooves
are discharged through the dispensing opening. At this time, a pill stopper is provided
at the top of the dispensing opening. The pill stopper closes the top of the pill
insertion grooves that are placed in line with the dispensing opening, so as to prevent
other pills contained in another pill insertion groove from being discharged through
the dispensing opening.
[0006] According to conventional methods, an installation of a pill stopper in a case is
difficult to perform. To address this problem, Korean Utility Model Registration No.
20-0438560 (published on February 22, 2008) discloses a coupling projection unit on one side of a pill case to allow for the
installation of a pill separation plate, which is equivalent to a pill stopper. The
coupling projection unit includes inserting projections on each side. The pill case
has an insertion hole at a position corresponding to the center of the coupling projection
unit. The pill separation plate with fixed projections is inserted into the insertion
hole. A cover having inserting grooves formed on both sides thereof is attached to
the coupling projection unit.
[0007] If the type of pills to be contained in the case changes, a rotor needs to be replaced
by another one having a width and height suitable for the different pills. According
to the related art, an insertion hole has to be altered in accordance with the width
and height of pill insertion grooves of the new rotor, so as to allow the pill separation
plate to be inserted through the case, and thus difficulties in efficiently adapting
to the rotor replacement occur.
SUMMARY
[0008] To address the problem mentioned above, provided is a pill cartridge for a medication
packaging apparatus with a stopper capable of being flexibly and conveniently adjusted
corresponding to different shapes of pills.
[0009] In one general aspect, a pill cartridge for a medication packaging apparatus, the
pill cartridge includes: a rotor to have a plurality of gear members protruding at
regular intervals along a circumference of the rotor and to have an insertion groove
formed between the plurality of gear members to thereby accommodate a pill; and a
case to comprise a collection chamber to accommodate the pill therein, a rotor housing
portion at a lower portion of the collection chamber to house the rotor, and a dispensing
opening formed on a lower portion of the rotor housing portion, wherein further comprises
a stopper of a planar shape to be additionally disposed above the dispensing opening
to close a top of the insertion groove, wherein the case comprises an installation
opening of a size that allows a height of the stopper to be adjustable when the stopper
is inserted in the case, wherein the installation opening is formed by an opening
portion on one side of the case, and wherein further comprises a stopper cover, which
is coupled to the opening portion and comprises a plurality of slits that is formed
in a longitudinal direction and into which one side of the stopper is inserted and
fixed so as to dispose the stopper in the installation opening.

[0014] An exemplary embodiment may include a rotor 100 to have a plurality of gear members
110 protruding at regular intervals along a circumference of the rotor 100 and have
insertion grooves 120 formed between the gear members 110 to thereby accommodate a
pill; and a case 200 to include a collection chamber 210 to accommodate the pill therein,
a rotor housing portion 220 at a lower portion of the collection chamber 210 to house
the rotor 100, and a dispensing opening 230 formed on a lower portion of the rotor
housing portion 220.
[0015] The rotor 100 may be connected with a rotator (not shown) at a lower portion thereof.
The rotor 100 rotates along with the rotator that is driven by a motor, such as a
rotation motor. The rotator and the rotation motor may be provided in a cartridge
base mounted on a lower portion of the case 200. The width and height of each insertion
groove 120 may be determined to conform to the shape of a pill 10 contained in the
case 200.
[0016] According to an exemplary embodiment, a planar stopper 300 may be additionally disposed
above the dispensing opening 230 to close a top of insertion grooves 120. Also, the
case 200 includes an installation opening 240 with a size that allows a height of
the stopper 300 to be adjustable when the stopper 300 is inserted in the case 200,
wherein the installation opening 240 is formed by an opening portion 250 on one side
of the case 200. Furthermore, the exemplary embodiment further includes a stopper
cover 400, which is coupled to the opening portion 250 and includes a plurality of
slits 422 and 425, which is formed in a longitudinal direction and into which one
side of the stopper 300 is inserted and fixed so as to dispose the stopper 300 in
the installation opening 240.
[0017] The stopper 300 is disposed to close a top of insertion grooves 120 positioned to
be connected to the dispensing opening 230. A portion of the stopper 300 that covers
the top of insertion grooves 120 may be larger than a top opening of the insertion
grooves 120. The stopper 300 may be designed to adapt to virtually all widths of the
insertion grooves 120, which may vary depending on the types of pills.
[0018] In another exemplary embodiment, a pusher may be additionally provided. The pusher
may rotate above the stopper 300 and push the pill mounted above the stopper 300 while
being fixed in the rotor 100 so as to keep the pill from remaining above the stopper
300. Also, an inclined plane, which is either straight or curved, may be formed above
the stopper 300, so that the pill above the stopper 300 may automatically slide and
free-fall.
[0019] The case 200 may include a collection chamber 210 to accommodate the pills. The case
200 may include a rotor housing portion 220 at a lower portion of the collection chamber
210 so as to house the rotor 100. The case 200 may have a dispensing opening 230 formed
on a lower portion of the rotor housing portion 220, corresponding to a position of
the stopper 300.
[0020] The case 200 may include a case body 201 and a case cover 202. The case body 201
includes the collection chamber 210, the rotor housing portion 220, and the dispensing
opening 230. The case body 201 is configured to have a top opening allowing the pills
to pass therethrough. The case cover 202 is hinged to a top edge of the case body
201 in such a manner to open and close the top opening of the case body 201.
[0021] A large number of pills may be contained in the collection chamber 210 of the case
200, and a single pill or a predetermined number of pills may be stored in each insertion
groove 120 of the rotor 100. As the rotor 100 rotates, the insertion grooves 112 change
positions and each is sequentially brought into line with the dispensing opening 230,
such that the pills in the insertion groove 120 are discharged through the dispensing
opening 230. In this state, the stopper 300 closes the top opening of the insertion
groove 120 placed in a line with the dispensing opening 230, and hence only the pills
contained in the insertion groove 120 in the position can be discharged through the
dispensing opening 230.
[0022] The case body 201 of the case 200 has an installation opening 240 with a length that
allows for the stopper 300 to adjust its height while being inserted into the installation
opening 240 which is formed by the opening portion 250 on one side of the case 200.
The stopper cover 400 is attached to the case 200 to close the opening portion 250,
and the plurality of slits 422 is formed on an inner side of the stopper cover 400
where the stopper 300 is inserted and fixed at an adjusted height. The plurality of
slits 422 may be used as space where one side of the stopper 400 is supported by being
inserted into the slits or put thereon.
[0023] As such, even when the height of the insertion grooves 112 changes as the types of
pills to be contained in the case 200 are changed, the height of the stopper 300 is
able to be adjusted within the installation opening 240 to correspond to the changed
height of the insertion grooves 120. The stopper 300 is coupled to the stopper cover
400 at the adjusted height. Therefore, it is possible to flexibly and conveniently
deal with the change of the height of the insertion hole 120 for different types of
pills.
[0024] In an exemplary embodiment, one side of the stopper 300, which faces the rotor 100,
may be concave in form with a curved line so as to have a curvature similar or identical
to a circumference curvature of the rotor 100. In such a case, the stopper 300 may
adhere to a surface of the circumference of the rotor 100, so that the pill accommodated
in the collection chamber 210 may not be lost through a gap between the rotor 100
and the stopper 300.
[0025] The stopper 300 may include: a stopper body 310 to close the top of insertion grooves
120 positioned to be connected to the dispensing opening 230; first extension ends
320 to extend from each side of the stopper body 310 toward the stopper cover 400;
second extension ends 330 that are bent inward and extend from the respective first
extension ends 320. The stopper cover 400 may include: a cover body 410 to be coupled
to the case 200 so as to close the opening portion 250; and a height adjustment portion
420. The height adjustment portion 420 is formed on an inner surface of the cover
body 410, and includes: guide grooves 421, into which the second extension ends 330
are inserted and which are formed to be concavely inserted in a longitudinal direction
on both sides; and the plurality of slits 422 formed in a longitudinal direction toward
the guide grooves 421 to support the second extension ends 330.
[0026] The stopper body 310 may have a size large enough to close the top of insertion grooves
120 positioned to be connected to the dispensing opening 230. The first extension
ends 320 extend from each side of the stopper body 310 toward the stopper cover 400.
The second extension ends 330 are bent inward and extend from the respective first
extension ends 320. The first extension ends 320 and the second extension ends 330
may together form an "L" shape.
[0027] The stopper cover 400 may include the cover body 410 and the height adjustment portion
420. The cover body 410 is coupled with the case 200 to close and open the opening
portion 250. The height adjustment portion 420 is formed along an inner surface of
the cover body 410. Guide grooves 421 may be formed to be concavely inserted in a
longitudinal direction into the stopper cover 400 on both sides of the height adjustment
portion 420, and guide the movement of the second extension ends 330. The first extension
ends 320 move along both sides of the height adjustment portion 420 when the second
extension portion 330 moves inside the stopper cover 400. The plurality of slits 422
is formed in a longitudinal direction to be concavely inserted into inner surfaces
on both sides, where the guide grooves 421 of the height adjustment portion 420 are
formed. As the plurality of slits 422 are formed in the height adjustment portion
420, the stopper 300 may be fixed to the stopper cover 400, either in a manner in
which the second extension ends 330 moving along the guide grooves 421 are inserted
to the plurality of slits 422 at positions corresponding to a size of a pill, or in
which some parts of the second extension ends 330 are supported by the slits 422.
[0028] The stopper 300 is made of an elastic material, and width W1 of each guide groove
421 is smaller than depth D1 of each second extension end 330. As mentioned above,
the stopper 300 may be made of an elastic material so that a gap between each of the
first extension ends 320 of the stopper 300 can be restored after the gap is changed
wider by an external force, which is then removed. For example, the stopper 300 may
be made of silicon, soft resin, rubber, etc., which have elasticity. As such, in a
case where the stopper 300 is made of an elastic material, even though the width W1
of each guide groove 421 is smaller than the depth D1 of each second extension end
330, the depth D1 is capable of moving along the guide grooves 421 while becoming
smaller. In this case, the second extension ends 330 may also be extended to the original
shape at positions where the plurality of the slits 422 is formed, so that the second
extension ends 300 may be fixed to the plurality of slits 422 by being pressed and
inserted.
[0029] FIG. 5 is another exploded perspective view illustrating an example of a stopper
cover and a stopper of a pill cartridge for a medication packaging apparatus according
to an exemplary embodiment. FIGS. 6 and 7 illustrate that a pill is discharged by
a pill cartridge for a medication packaging apparatus according to exemplary embodiments.
[0030] In an exemplary embodiment, a stopper 300 may include: a stopper body 310 to close
a top of insertion grooves 120 positioned to be connected to a dispensing opening
230; a third extension end 340 to extend from a middle of one side of the stopper
body 310 toward the stopper cover 400; and fourth extension ends 350 that extend from
the third extension end 340 to protrude from the both sides of the third extension
end 340. The stopper cover 400 may include: a cover body 410 to be coupled to a case
200 so as to close an opening portion 250; and a height adjustment portion 420. The
height adjustment portion 420 is formed on an inner surface of the cover body 410,
and includes: a vertical groove 423, into which the third extension end 340 is inserted,
and a horizontal groove 424, into which the fourth extension ends 350 are inserted,
wherein the horizontal groove 424 is formed to be concavely inserted in a longitudinal
direction on a surface toward the stopper 300; and a plurality of slits 425 formed
in a longitudinal direction toward the horizontal groove 424 to support the fourth
extension ends 350.
[0031] As mentioned above, the stopper body 310 may have a size large enough to close the
top of insertion grooves 120 positioned to be connected to a dispensing opening 230.
The third extension end 340 extends from a middle of one side of the stopper body
310 toward the stopper cover 400. The fourth extension ends extend from the third
extension end 340 to protrude from the both sides of the third extension end 340.
The third extension end 340 and the fourth extension ends 350 may together form a
"T" shape.
[0032] The stopper cover 400 may include the cover body 410 and the height adjustment portion
420. The cover body 410 is coupled to the case 200 to close and open an opening portion
250. The height adjustment portion 420 is formed along an inner surface of the cover
body 410. The height adjustment portion 420 may include the vertical groove 423 in
the middle thereof to be concavely inserted in a longitudinal direction into an inner
surface on a side toward the stopper 300, and the vertical groove 423 may guide the
movement of the third extension portion 340. In addition, the vertical groove 423
and the horizontal groove 424 may together form a "T" shape on both sides of the vertical
groove 423, and the horizontal groove 424 may guide the movement of the fourth extension
portion 350.
[0033] The plurality of slits 425 is formed in a longitudinal direction to be concavely
inserted into inner surfaces on the side, where the horizontal groove 424 of the height
adjustment portion 420 is formed. In response to the plurality of slits 425 formed
in the height adjustment portion 420, the stopper 300 may be fixed to the stopper
cover 400, in a manner that the fourth extension ends 350 moving along the horizontal
groove 424 are inserted to the plurality of slits 425 at positions corresponding to
a size of a pill, or in a manner that some parts of the fourth extension ends 350
are supported by the slits 425.
[0034] The stopper 300 is made of an elastic material, and width W2 of the horizontal groove
424 is smaller than depth D2 of each fourth extension end 350.
[0035] As mentioned above, the stopper 300 may be made of an elastic material so that gaps
between the third extension end 340 and the fourth extension ends 350 can be restored
after the gaps are changed wider by an external force, which is then removed. For
example, the stopper 300 may be made of silicon, soft resin, rubber, etc. As such,
in a case where the stopper 300 is made of elastic material, even though the width
W2 of the horizontal groove 424 is smaller than the depth D2 of the fourth extension
ends 350, the depth D2 is capable of moving along the horizontal groove 424 while
becoming smaller. In this case, the fourth extension ends 350 may also be extended
to the original shape at positions where the plurality of the slits 425 is formed,
so that the fourth extension ends 350 may be fixed to the plurality of slits 425.
[0036] The rotor 100 may form, at regular intervals, a plurality of coupling grooves 130
which are concavely inserted into an inner surface along the circumference thereof,
and gear members 110 are fixed to the coupling grooves 130 according to a size corresponding
to a shape of a pill accommodated in a collection chamber 210.
[0037] A size of the insertion groove 120 may be adjusted according to the shape of the
pill contained in the case 200. Conventionally, as a type of a pill accommodated in
the case 200 changes, the rotor 100 is changed to another rotor with a size of an
insertion groove corresponding to the different types of pills. However, exemplary
embodiments of a pill cartridge for a medication packaging apparatus are capable of
adjusting the size of the insertion groove 120 to the changed pill without changing
the rotor 100. According to the exemplary embodiment, if the coupling grooves 130
are formed along the circumference of the rotor 100, one end on one side of each gear
member 110 is inserted and fixed to each coupling groove 130. In this case, the gear
members 110 may be inserted and fixed by selecting the coupling grooves 130 according
to the shape of the pill and the corresponding position. There may be the plurality
of the gear members 110. In addition, the desired number of the gear members 110 may
be fixed to each of the coupling grooves 130 of various heights, and a size of the
insertion groove 120 may be readily adjusted according to the width and height of
the fixed gear members 100. Moreover, the gear members 110 and the rotor 100 may be
fixed to or separated from each other by using various well-known coupling elements
that are detachable. For example, the gear members 110 may include snap projections,
and the rotor 100 may include snap grooves at regular intervals along the circumference.
[0038] As mentioned above, the exemplary embodiments of a pill cartridge for a medication
packaging apparatus is capable of immediately changing the stopper 300 according to
the shape of the changed pill in a case where the type of the pill contained in the
case 200 is changed. Although the accommodated pill is changed, the exemplary embodiments
may adjust the size of the insertion groove 120 corresponding to the shape of the
changed pill without the replacement of the rotor 100, so that the exemplary embodiments
have advantages of flexibly and conveniently dealing with different pill sizes.
[0039] The methods and/or operations described above may be recorded, stored, or fixed in
one or more computer-readable storage media that includes program instructions to
be implemented by a computer to cause a processor to execute or perform the program
instructions. The media may also include, alone or in combination with the program
instructions, data files, data structures, and the like. Examples of computer-readable
storage media include magnetic media, such as hard disks, floppy disks, and magnetic
tape; optical media such as CD ROM disks and DVDs; magneto-optical media, such as
optical disks; and hardware devices that are specially configured to store and perform
program instructions, such as read-only memory (ROM), random access memory (RAM),
flash memory, and the like. Examples of program instructions include machine code,
such as produced by a compiler, and files containing higher level code that may be
executed by the computer using an interpreter. The described hardware devices may
be configured to act as one or more software modules in order to perform the operations
and methods described above, or vice versa. In addition, a computer-readable storage
medium may be distributed among computer systems connected through a network and computer-readable
codes or program instructions may be stored and executed in a decentralized manner.
[0040] A number of examples have been described above. Nevertheless, it should be understood
that various modifications may be made. For example, suitable results may be achieved
