Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to drug delivery devices. [Background technology]

[0002] Conventionally, there is known a medicine supplying device that supplies a plurality of medicines in individual packets. For example, as disclosed in Patent Document 1, the medicine supplying device appropriately discharges medicines (medicines) such as tablets and capsules written on a prescription (prescription data) from a discharge drum in a tablet case, collects them in a hopper through a chute, and then packages (divides) them into individual packets in wrapping paper.

[0003] The medicines are packaged in a medicine packaging device located below the hopper. The medicine packaging device has a nozzle that discharges the medicine from the hopper. A wrapping paper with a V-shaped cross section that has been pre-folded in half along the length is conveyed below this nozzle, and the medicine is dispensed into the wrapping paper through the nozzle and sealed by heat welding.

[0004] The medicine packaging device dispenses medicine into a wrapping paper whose starting end (downstream end) is sealed by heat welding, and transports the wrapping paper downstream at the width of one package (transport pitch).The medicine is then packaged by sealing the ending end (upstream end) and top edge of the wrapping paper by heat welding.

[0005] After the medicine is poured into the packaging paper, the end portion is sealed together with the top edge by heat welding, forming a welded portion together with the start portion, which becomes the downstream end of the package where the medicine is poured next. The medicine packaging device pours medicine into the packaging paper, conveys the packaging paper, and repeatedly seals it by heat welding, thereby packaging multiple medicines. The packaging paper containing the medicine can be separated into individual packets at the welded portion. [Prior art documents] [Patent documents]

[0012] Hereinafter, an embodiment of the drug supply device of the present disclosure will be described with reference to the drawings. Hereinafter, as indicated by the arrows in FIG. 1 , the side where operation unit 11 is located will be referred to as the front of drug supply device 1, and the opposite side will be referred to as the rear of drug supply device 1. Furthermore, the left and right sides of drug supply device 1 when viewed from the front will be referred to as the left and right sides of drug supply device 1. Furthermore, the side away from the surface on which drug supply device 1 is installed will be referred to as the top of drug supply device 1, and the opposite side will be referred to as the bottom of drug supply device 1.

[0013] Fig. 1 is a perspective view showing an example of a medicine supply device 1, and Fig. 2 is a longitudinal sectional view of the medicine supply device 1. As shown in Fig. 1, the medicine supply device 1 has a first floor section 10 and a second floor section 20.

[0014] The first floor section 10 includes an operation section 11 and a take-out section 12. The first floor section 10 also includes an input section (not shown).

[0015] The operation unit 11 is a device operated by an operator, and includes, for example, a display, operation buttons, etc. Various information is input to the medicine supply device 1 by the operator operating the operation unit 11.

[0016] Medicines packaged in medicine supply device 1 are taken out from outlet 12. Outlet 12 has an opening, and an operator takes out the medicines from the opening.

[0017] The input unit is an input device that receives various information from external devices. For example, the input unit is connected to a personal computer, and receives information about a prescription issued by a medical institution from the personal computer.

[0018] As shown in Fig. 2, the medicine supply device 1 includes a medicine supply unit 13, a packaging unit 14, and a control unit (not shown) that controls the medicine supply device 1. The medicine supply unit 13 supplies medicines to a medicine delivery position Pr (see Figs. 2 and 3). The medicine supply unit 13 includes a plurality of shelves 13a and a hopper 13b. The packaging unit 14 is disposed on the first floor 10, and the medicine supply unit 13 is disposed across the upper part of the first floor 10 and the second floor 20.

[0019] The shelves 13a are arranged on the second floor 20 to store the cassettes C in a shared manner. The medicine supply device 1 includes 20 shelves 13a. The shelves 13a are arranged in five vertical rows and four horizontal rows. The number and arrangement of the shelves 13a on the second floor 20 are not limited to those in this embodiment, and the number of vertical rows and / or horizontal rows may be more or less than those described above.

[0020] Each of the shelves 13a stores a plurality of cassettes C on both the left and right sides of the shelf 13a along the front-rear direction. Each cassette C stores a plurality of medicines. Each of the cassettes C is configured to discharge one medicine tablet at a time.

[0021] The medicines discharged from the cassette C fall down the passage W and are discharged onto the first floor 10. The passage W is provided so as to penetrate each of the plurality of shelves 13a in the vertical direction.

[0022] Hopper 13b receives the medicines discharged onto first floor 10 and discharges the received medicines from discharge port 13c to nozzle 50 (see FIG. 3) of packaging unit 14. An upper opening H1 (see FIG. 4) of nozzle 50 is disposed directly below discharge port 13c.

[0023] FIG. 3 is a schematic diagram showing the overall configuration of the packaging unit of the medicine supply device.

[0024] The packaging unit 14 packages the medicines released from the hopper 13b. The medicines are packaged in wrapping paper H extending in the longitudinal direction to form sachets 36 (see FIGS. 4 and 6) whose width is the longitudinal direction of the wrapping paper H.

[0025] The packaging unit 14 includes a roll 31 , a printer 33 , a filling unit 40 (nozzle 50 , sealing device 60 ), a roller 72 , a cutter 76 , a conveyor 78 , and a motor 79 .

[0026] The roll 31 is provided with a roll of heat-sealable wrapping paper H that can be pulled out. The wrapping paper H is a strip that extends in the longitudinal direction and is folded in half, with the top surface open and the bottom folded in half to form a roughly V-shaped cross section. The wrapping paper H on the roll 31 is pulled out toward the printer 33 and filling unit 40 by the rotational drive of roller 72.

[0027] The rollers 72, together with a motor 73 for driving the rollers 72, and a conveyor 78 and a motor 79 for driving the conveyor 78, constitute a conveying section for conveying the strip-shaped packaging paper H to contain and package medicines.

[0028] The printer 33 is a printing machine that prints, for example, the patient's name, the name of the medicine supplied on the wrapping paper, the date and time of administration, and the like on the surface of the wrapping paper H that is conveyed by the rollers 72.

[0029] The filling unit 40 has a nozzle 50 that guides the medicine from the hopper 13b into the wrapping paper H, and a sealing device 60 that seals the wrapping paper in which the medicine is wrapped. In the filling unit 40, the medicine is packed into the wrapping paper H, and the overlapping portions of the wrapping paper H in which the medicine is packed are sealed (forming a welded portion) to separate the medicine into individual packets. This will be described in detail later.

[0030] The cutter 76 cuts the welded portion (which may also be called a seal) of the wrapping paper H, or forms a cuttable broken-line slit in the welded portion.

[0031] The conveyor 78 conveys the wrapping paper H that has been divided into individual packages and cut to the take-out opening 12, and is provided sequentially along the conveying path of the wrapping paper H.

[0032] In the packaging unit 14, the wrapping paper H is pulled diagonally downward to the right from the roll 31 by rollers 72 and the like, and then the surface is printed by the printer 33. Next, in the filling unit 40, medicine is dispensed into the wrapping paper H from the nozzle 50, and the wrapping paper H is divided into individual packets and packaged by the sealing device 60. The divided and packaged wrapping paper H is cut by a cutter 76 and transported by a conveyor 78 towards the outlet 12.

[0033] The conveyor 78 transports the individually packaged wrapping paper H from the cutter 76 at the lower right in FIG. 3 toward the outlet 12 at the upper left.

[0034] Fig. 4 is an enlarged cross-sectional view showing the main components of the filling unit, and Fig. 5 is a perspective view of the tip of the nozzle for explaining the medicine position adjustment unit. Note that, since the wrapping paper H is translucent in Fig. 4, for convenience, each component constituting the filling unit 40 is shown schematically with solid lines. Furthermore, hatched areas in the wrapping paper H shown in Fig. 4 are welded areas.

[0035] The nozzle 50 guides the medicine from the hopper 13b into the packaging paper H and stores it therein. The nozzle 50 has a rectangular cylindrical shape with openings in the vertical direction, and is arranged to extend vertically, for example. The upper opening of the nozzle 50 is positioned opposite the discharge port 13c of the hopper 13b, and the medicine received by the hopper 13b enters the nozzle 50 and is guided by the insertion guide piece 54 to be poured into the packaging paper H.

[0036] The nozzle 50 has a nozzle body 52 , a shutter portion 53 , an insertion guide piece 54 , and a closure guide piece 58 .

[0037] The shutter portion 53 is provided on the upper portion of the nozzle body 52, and can freely open and close the opening of the nozzle body 52, and dispenses the medicine contained in the wrapping paper H one packet at a time.

[0038] The insertion guide piece 54 protrudes downward from the lower end of the nozzle body 52 and is inserted into the inside of the folded wrapping paper H. The insertion guide piece 54 protrudes, for example, in the vertical direction, which is the same direction as the extension direction of the nozzle. The insertion guide piece 54 has a shape in which the thickness in the thickness direction of the wrapping paper H gradually narrows toward the tip 54a. The insertion guide piece 54 is inserted into the wrapping paper H from the upper opening H1 of the wrapping paper H and holds the wrapping paper H in a V-shaped cross section.

[0039] As a result, the insertion guide piece 54 uses its tip 54a to position the height of the folded portion Ha at the bottom end of the folded wrapping paper H, and also keeps the wrapping paper H open at the top, making it easier to insert the medicine that falls from inside the nozzle body 52 through the upper opening H1.

[0040] Specifically, the insertion guide piece 54 is disposed opposite to and spaced from the welded portion S of the package H, and when the wrapping paper H is folded in half at the fold Ha, the insertion guide piece 54 is inserted into the wrapping paper H upstream of the welded portion S, thereby opening the upper end of the wrapping paper H. The insertion guide piece 54 is provided with a position adjustment portion 56 that protrudes downstream and adjusts the position of the medicine inside the wrapping paper H.

[0041] The tip 56a of the position adjustment unit 56 is positioned vertically higher than the fold Ha. As a result, the position adjustment unit 56 contacts the medicine Y placed in the wrapper H from the upstream side and positions the medicine Y in an upright state, moving it toward the downstream welded portion S. Note that the tip 56a of the position adjustment unit 56 does not need to be positioned vertically higher than the fold Ha, as long as it positions the medicine placed in the wrapper H in an upright state. Positioning the medicine in an upright state, moving it toward the downstream welded portion S, can prevent the medicine from being pinched by the welded portion S when the wrapper is packaged. For example, the tip 56a of the position adjustment unit 56 may be positioned away from the tip 54a of the insertion guide piece 54 in a direction perpendicular to the conveyance direction of the wrapper H, which is conveyed at a downward incline downstream. Furthermore, the tip 56a of the posture adjustment unit 56 may be disposed at the same distance from the fold Ha in a direction perpendicular to the conveying direction as the tip 54a of the insertion guide piece 54. In this case, if the conveying direction is inclined downstream, the tip 56a of the posture adjustment unit 56 is located lower than the tip 54a of the insertion guide piece 54.

[0042] For example, as shown in Fig. 4, the posture adjustment unit 56 is configured to contact the medicine Y from the upstream side and tilt the medicine Y from a vertically upright state centered on the lower end of the medicine Y toward the downstream side at an angle of 90 degrees or less with respect to the horizontal. Since the medicine Y is dispensed into the wrapping paper H, the posture adjustment unit 56 positions the lower end of the medicine Y at a position closest to the fold Ha of the wrapping paper H, and positions the upper end of the medicine Y downstream in the conveying direction from the vertical direction. As a result, even if the wrapping paper H into which the medicine has been dispensed is conveyed downstream and positioned at a position where the welded portion S is formed by the vertical seal unit 61, the medicine will not be positioned at that position.

[0043] The position of the tip 56a of the attitude adjustment part 56 is set according to the shape of the medicine to be dispensed into the wrapping paper H and the size of the area in the wrapping paper H into which the medicine will be dispensed.

[0044] In order to package the medicines in the wrapping paper H, it is preferable that the size of the medicines to be inserted into the wrapping paper H is a relatively large size that is versatile, and it is expected that multiple (two) medicines of that size will be inserted. For example, the length L along the extension direction of the wrapping paper H from the tip 56a of the position adjustment unit 56 to the welding portion S is preferably 13.2 mm to 17.2 mm or more. This length L is more preferably 14.2 mm to 16.2 mm or more, and even more preferably 15.2 mm or more (enough to accommodate the width of two No. 0 capsules). The position adjustment unit 56 is preferably positioned at a position where the length L is a distance that allows at least two No. 0 capsule medicines to be inserted. Even if one or more medicines smaller than this size are inserted, they will not be positioned at the sealing position when transported to the sealing device 60. Furthermore, even when multiple capsules of sizes 00 and 000 are inserted, the capsules may be moved toward the downstream side, i.e., toward the welded portion S, tilted toward the downstream side, and the upstream end may be sealed with the sealing device 60 so that they can be conveniently packaged.

[0045] Furthermore, even if a drug smaller than 15.2 mm is placed into the packaging paper H and transported to the sealing device, as shown by drug Y3 overlapping drug Y2, drug Y will not be located in the part (sealed part S) that is welded by the vertical parts 62a, 63a of the vertical seal part 61 (see Figure 6).

[0046] Furthermore, although the position adjustment unit 56 is configured to protrude from the insertion guide piece 54, it is not limited thereto, and may be formed integrally with the insertion guide piece 54 by processing a portion of the insertion guide piece 54 so as to protrude downstream to form a tip portion 56a. The position adjustment unit 56 may also be detachably attached to the insertion guide piece 54. If the position adjustment unit 56 is provided integrally with the insertion guide piece 54, the number of parts can be reduced, and assembly of the medicine supply device 1 can be made easier. If the position adjustment unit 56 is detachably attached to the insertion guide piece 54, the position adjustment unit 56 can be changed depending on the size, number of medicines, transport speed, etc., and suitable packaging can be performed accordingly.

[0047] As a result, the medicine inside the wrapping paper H is sandwiched between the folded portions near the fold Ha at the bottom end of the wrapping paper H, and abuts against the tip end 56a, so that it is contained in an attitude that is tilted downstream rather than upstream.

[0048] The posture adjustment section 56 determines the length of the folded section Ha in the wrapping paper H from the lower end of the welded section S (the end on the folded section Ha side) along the longitudinal direction of the wrapping paper H, and together with one side of the welded section S, forms an approximately triangular bag portion, which becomes the small pouch 36A that contains the medicine to be added.

[0049] The closure guide piece 58 is disposed opposite the insertion guide piece 54 and has the function of closing the upper opening H1 of the wrapping paper H. The closure guide piece 58 clamps the upper end of the wrapping paper H that has been opened by the insertion of the insertion guide piece 54, with the medicine contained therein, thereby closing the opening H1 of the wrapping paper H.

[0050] The sealing device 60 is a device that seals the packaging paper in which the medicine is wrapped. The sealing device 60 divides the wrapping paper H into individual packages by heat welding using a heater block 62. The individually packaged wrapping paper H is then cut at a predetermined timing by a cutter 76 and transported to the outlet 12 by a conveyor 78.

[0051] The sealing device 60 is disposed adjacent to the nozzle 50 on the downstream side in the conveying direction, and has the function of sealing the opening H1 on the upper side of the wrapping paper H by thermal welding of the folded ends, and also of separating each package.

[0052] As shown in Figure 6, the sealing device 60 has a heater block 62 and a pressure-contact receiving block 63 that are arranged opposite each other with a predetermined distance between them. The heater block 62 is provided with an operating unit 64 (see Figure 4) that includes a motor 66. This operating unit 64 is configured so that, when driven by the motor 66, the heater block 62 can be pressed against or separated from the opposing pressure-contact receiving block 63. The pressure-contact receiving block 63 is configured to receive and receive pressure from the heater block 62, and the wrapping paper is sandwiched between the heater block 62 and the pressure-contact receiving block 63. When electricity is applied to the heater block 62, the heater block 62 generates heat to a predetermined temperature and heats and welds the wrapping paper sandwiched between the heater block 62 and the pressure-contact receiving block 63.

[0053] The heater block 62 and the pressure-contact receiving block 63 are each composed of vertical portions 62a, 63a and parallel portions 62b, 63b. The vertical portions 62a, 63a are provided so as to extend in the up-down direction in Fig. 6 (the short-side direction of the wrapping paper H, also referred to as the width direction of the wrapping paper H). The parallel portions 62b, 63b are provided so as to extend from the upper ends of the vertical portions 62a, 63a downstream in the feeding direction of the wrapping paper H (the longitudinal direction of the wrapping paper H).

[0054] 4 and 6, the heater block 62 and the pressure-contact receiving block 63 are in an inverted L shape. The vertical portions 62a, 63a of the heater block 62 and the pressure-contact receiving block 63 form the vertical seal portion 61. The vertical portions 62a, 63a sandwich the wrapping paper H being conveyed from both sides and thermally seal the wrapping paper H from the folded portion Ha side to the upper opening H1, thereby forming the welded portion S.

[0055] The welded portion S fixes the downstream end of the wrapping paper H in a direction perpendicular to the conveyance direction and extends in the direction perpendicular to the conveyance direction. The welded portion S serves as a reference for the position of the position adjustment unit 56. As a result, a substantially triangular pouch portion (pouch 36A) is formed in the wrapping paper H on the upstream side of the sealing device 60, surrounded by the welded portion S and the folded portion Ha, with the upper opening H1 remaining unwelded. As described above, the medicine is dispensed into this pouch portion (pouch 36A) from the nozzle 50. Furthermore, the parallel portions 62b, 63b heat-seal the upper opening H1 of the wrapping paper H downstream of the vertical portions 62a, 63a.

[0056] The wrapping paper H that has been heat-sealed by the sealing device 60 is transported further downstream at a predetermined pitch by the rotation of the roller 72. The predetermined pitch is, for example, the pitch from the position where the medicine is poured into the wrapping paper H to the position where the welded portion is formed, in other words, the length in the extension direction of the wrapping paper H that becomes the width N of the sachet bag formed by packaging.

[0057] Heater block 62 and pressure contact receiving block 63 heat-seal packaging paper H, thereby forming sachet 36 (see FIG. 4) containing medicines, with the exception of folded portion Ha, on the downstream side (pull-in roller 72 side) of vertical portions 62a, 63a of heater block 62 and pressure contact receiving block 63. At the same time, heater block 62 and pressure contact receiving block 63 form pouch 36A (see FIG. 4) on the upstream side of vertical portions 62a, 63a.

[0058] Vertical teeth (not shown) extending in the up-down direction are built into the vertical portion 63a of the pressure contact receiving block 63. Meanwhile, vertical portion 62a of heater block 62 is provided with vertical tooth receiving portions 62c at portions corresponding to the vertical teeth (not shown) for receiving the vertical teeth (not shown).

[0059] These vertical teeth and vertical tooth receiving portions 62c are formed to a length that extends from the bottom end to the remaining top end in the vertical direction of the wrapping paper H. As a result, when the wrapping paper H is thermally welded from the folded portion Ha to the upper opening H1, the vertical teeth and vertical tooth receiving portions 62c form a perforation (a perforated hole) at approximately the center of the width of the welded portion (from the folded portion Ha to the edge of the upper opening H1).

[0060] Sachet 36 is heat-sealed on three sides (the remaining side is fold Ha) and is closed all around. Sachet 36 is configured so that it can be separated from other sachets 36 by cutting along the perforations. Note that vertical seal portion 61 of heater block 62 and pressure-contact receiving block 63 has gaps 65 around the vertical teeth (or vertical tooth receiving portions 62c). Due to these gaps, the wrapping paper H is not welded around the perforations formed by the vertical teeth and vertical tooth receiving portions 62c.

[0061] According to the medicine supply device 1 of the embodiment of the present invention, even when multiple medicines are placed in the wrapping paper H and packaged, the medicines are positioned downstream in the wrapping paper H at the welded portion, which is the downstream edge in the conveying direction, without tilting toward the upstream side in the conveying direction. As a result, the medicines contained in the wrapping paper H are not positioned at the position that will be welded when the upstream end is welded (the position where the welded portion is formed, and the position that will be sandwiched by the vertical seal portion 61). Therefore, when medicines are placed in the wrapping paper H and packaged by welding to seal them, the medicines are not sandwiched in the welding device, and can be packaged appropriately.

[0062] According to the medicine supply device 1, even when the size of the medicine dispensed into the wrapping paper H is large, the posture adjustment unit 56 can prevent the medicine dispensed into the wrapping paper H from moving upstream and being caught in the welded portion formed by thermal welding in the wrapping paper H. As a result, the medicine supply device 1 according to this embodiment can accommodate multiple medicines regardless of their size and dispense the medicines appropriately packaged one by one.
