[0023] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

[0024] First, FIG. 1 is an overall configuration diagram of a dual capsule molding machine according to one embodiment of the present invention.

[0025] A dual capsule molding machine according to one embodiment of the present invention includes a molding roller (100), a liquid storage unit (200), a liquid supply unit (300), a quantitative supply unit (400), and a supply line (500).

[0026] The above-mentioned molding roller (100) has a molding groove (120) formed on its outer surface in the shape of half of a capsule to heat-seal two gelatin films supplied from the molding drum (20) and simultaneously mold them into a capsule shape into which two types of medicinal liquids are injected, and each molding roller (100) is configured to rotate in opposite directions while facing each other in close proximity with the molding grooves (120) arranged to correspond to each other.

[0027] Referring to FIGS. 2 and 3, the molding roller (100) may include a roller body (110), a molding groove (120), and an air discharge hole (130).

[0028] The roller body (110) is configured as a pair and is formed as a cylindrical shape with an open interior, and a motor is connected to one side to rotate in different directions.

[0029] The above-mentioned molding grooves (120) are each formed on the outer surface of the roller body (110) and are engraved in the shape of half of a capsule.

[0030] The gelatin film (G) is supplied to the outer surface of the roller body (110) and can be supplied while covering the molding groove (120). A certain amount of liquid medicine can be injected while covering the molding groove (120).

[0031] The above-mentioned molding groove (120) may include a first groove portion (121), a second groove portion (122), and a separation portion (123).

[0032] That is, the molding groove (120) has a first groove (121) formed on one side centered on the separation part (123) and a second groove (122) formed on the other side, and a single capsule can be molded by injecting different types of medicinal liquid into the first groove (121) and the second groove (122), respectively.

[0033] The first groove (121) is formed on the outer surface of the roller body (110) and is a groove formed so that one of the different types of medicinal liquids can be injected.

[0034] The second groove (122) is formed on the outer surface of the roller body (110) and is formed to face the first groove (121) so that one of the different types of medicinal liquids can be injected.

[0035] The cross-section of the first and second grooves (121) (122) may vary depending on the shape of the capsule and may have a circular or elliptical shape.

[0036] Referring to FIG. 4, the separation portion (123) may be formed between the first groove portion (121) and the second groove portion (122).

[0037] The separator (123) separates the space of the first groove (121) and the second groove (122) respectively.

[0038] The separation part (123) may include a deformation space (123a) and a volume forming part (123b).

[0039] The above deformation space (123a) can be formed as an intaglio on the plane of the separation part (123).

[0040] The cross-section of the deformation space (123a) can be formed as a curve or a right angle depending on the type of capsule.

[0041] In the above deformation space (123a), when the pressure projection (124) presses the gelatin film (G) by the rotation of the roller body (110), the shape of the gelatin film can be deformed within the deformation space (123a).

[0042] The above volume forming part (123b) may be formed on the second pressure projection (124b) of the pressure projection (124) to be described later.

[0043] That is, the volume forming part (123b) is formed at a certain angle on a part of the second pressure protrusion (124b), the second pressure protrusion (124b) functions as a blade, and the volume forming part (123b) presses the gelatin film and pushes the gelatin film toward the deformation space (123a) to form a convex volume.

[0044] As described above, by forming a volume in the center of the capsule through the volume forming part (123b), the capsule is separated so that different drug liquids do not mix with each other, and at the same time, the capsule can be safely stored by preventing the central part of the capsule from bending or being cut.

[0045] A pressure projection (124) may be formed protruding from the edges of the first and second grooves (121) (122) and the separation part (123).

[0046] The above pressure projection (124) functions as a blade that presses and cuts the gelatin film (G) to form a capsule shape after the different type of medicine liquid is injected.

[0047] The pressure projection (124) may include a first pressure projection (124a) and a second pressure projection (124b).

[0048] The first pressure projection (124a) is formed protrudingly on the edge portions of the first groove (121) and the second groove (122) of the molding groove (120).

[0049] The first pressure projection (124a) presses the gelatin film (G) when the pair of roller bodies (110) rotate, thereby forming both sides of the capsule into which the different types of medicine liquids are injected, namely the first medicine liquid section (C1) and the second medicine liquid section (C2).

[0050] The second pressure projection (124b) can be formed protruding from the edge of the separation part (123).

[0051] The second pressure projection (124b) may be formed integrally with the first pressure projection (124a), or they may be formed separately.

[0052] The second pressure projection (124b) presses the edge of the gelatin film (G) located in the separation part (123) and forms the central part of the capsule (C), i.e., the compartment (C3), between the first drug part (C1) and the second drug part (C2).

[0053] The above air exhaust holes (130) can each be formed through the molding groove (120).

[0054] Since the above capsule (C) is configured such that a molding part (120) is separated into a first groove (121) and a second groove (122) to allow injection of a different type of medicinal liquid, an air exhaust hole (130) can also be formed in the first groove (121) and the second groove (122), respectively.

[0055] The air exhaust port (130) can be divided into a first exhaust port (131) and a second exhaust port (132).

[0056] The first discharge hole (131) can be formed through the first groove (121), and the second discharge hole (132) can be formed through the second groove (122).

[0057] The first discharge port (131) and the second discharge port (132) can each communicate with the outside through different channels.

[0058] Accordingly, when a different type of liquid is injected into the gelatin film located in the first groove (121) and the second groove (122), air can be discharged to the outside through the first discharge hole (131) and the second discharge hole (132) to the extent that the gelatin film is deformed.

[0059] Additionally, referring to FIG. 5, the liquid storage unit (200) is fixed to the upper part of the main body (1) of the capsule molding machine, and a certain amount of liquid can be stored inside.

[0060] The liquid storage unit (200) is for supplying a different type of liquid and may include a separating body (210), a storage container (220), and a nozzle unit (240).

[0061] The above separation body (210) is fixed to the upper part of the main body (1) of the capsule molding machine and is for mounting storage containers (220) respectively.

[0062] The separating body (210) has a vertical partition (211) formed in the central part to separate each storage container (220).

[0063] A supply channel is formed inside the separation body (210) so that a different type of liquid can be supplied and connected to the nozzle part (240).

[0064] Fixing pieces (212) are formed on both lower sides of the above-mentioned separation body (210) to press against the outer side of each storage container (220), thereby holding the storage container (220) when an external force is applied or shaking occurs, so as to increase stability.

[0065] The above storage container (220) can be formed into two storage containers (220) (220') respectively so that a certain amount of different types of medicine liquid can be stored.

[0066] For example, one of the two storage containers (220) may store a medicinal solution of vitamins such as vitamins A, B, C, and D, or minerals such as sodium, potassium, chlorine, calcium, magnesium, phosphorus, iron, zinc, copper, manganese, cobalt, chromium, and iodine, and the other storage container (220') may store a medicinal solution for the purpose of prevention, such as diabetes, hypertension, and cardiovascular disease.

[0067] In other words, it becomes possible to manufacture a single capsule by injecting two different liquid medications with different properties into separate capsules.

[0068] The nozzle part (240) is formed at the lower part of the separation body (210) and receives a different type of chemical solution from a supply channel formed inside the separation body (210), and supplies the received chemical solution to the supply line (500).

[0069] A supply channel for supplying different types of liquids is formed inside the nozzle part (240), and the supply channel is connected to a supply line (500).

[0070] The above separation body (210) and nozzle part (240) are connected through a supply pipe (230).

[0071] The above supply pipe (230) receives the liquid medicine from the supply path of the separation body (210) and delivers the supplied liquid medicine to the nozzle part (240).

[0072] Additionally, referring to FIG. 6, the liquid supply unit (300) is positioned between a pair of molding rollers (100) and is configured to inject a different type of liquid supplied through a supply line (500) into a gelatin film (G) shaped like half a capsule located in the first groove (121) and the second groove (122).

[0073] The above liquid supply unit (300) may include a supply body (310), a contact surface (320), and an injection unit (330).

[0074] The supply body (310) is positioned between a pair of molding rollers (100), and a supply channel is formed inside to supply different types of liquid medicines, and the supply line (500) can be connected to the supply channel.

[0075] The above contact surface (320) is formed in a curve at the lower part of the supply body (310) and adheres to the outer surface of a pair of molding rollers (100). Accordingly, the gelatin film (G) supplied from the molding drum (20) is prevented from lifting off the outer surface of the molding rollers (100).

[0076] The injection portion (330) is formed on each contact surface (320).

[0077] The injection part (330) is formed as a set of two holes into which the liquid medicine is injected.

[0078] That is, the injection part (330) may include a first injection hole (331) and a second injection hole (332) so that a different type of drug solution is injected.

[0079] The first injection hole (331) is a hole into which a medicinal liquid having one medicinal property is injected, and the second injection hole (332) is a hole into which a medicinal liquid having another medicinal property is injected.

[0080] The first injection hole (331) is configured to inject a liquid medicine into the first groove (121) formed in the molding roller (100), and the second injection hole (332) is configured to inject a liquid medicine into the second groove (122).

[0081] In addition, the above quantitative supply unit (400) is installed at the bottom of the liquid storage unit (200).

[0082] The quantitative supply unit (400) may be identical to an ejector structure and controls the supply of the liquid medicine supplied through the supply line (500) in fixed amounts.

[0083] The above quantitative supply unit (400) is connected to the first line (510) and the second line (520) of the supply line (500) simultaneously, and the first line (510) and the second line (520) are respectively connected to the first injection port (331) and the second injection port (332) of the liquid medicine supply unit (300).

[0084] Additionally, the supply line (500) is configured to receive a different type of liquid from the liquid storage unit (200) and supply it to the liquid supply unit (300).

[0085] The above supply line (500) connects the liquid storage unit (200) and the quantitative supply unit (400), and connects the quantitative supply unit (400) and the liquid supply unit (300).

[0086] The supply line (500) can use a flexible hose and can be divided into a first line (510) and a second line (520).

[0087] The first line (510) is connected to the nozzle part (240) to receive the liquid medicine, and the first line (510) supplies the liquid medicine stored in one of the two storage tanks (220) to the liquid medicine supply part (300), and the second line (520) supplies the liquid medicine stored in the other storage tank (220') to the liquid medicine supply part (300).

[0088] That is, the first line (510) and the second line (520) each supply a medicinal liquid with different medicinal properties to the medicinal liquid supply unit (300).

[0089] Additionally, referring to FIG. 7, the molding roller (100) may include an air discharge control unit (600) provided on the side of the molding roller (100) to control the amount of air discharged through the air discharge hole (130).
