(1) Outline of Molded Body Manufacturing Apparatus First, an outline of a molded body manufacturing apparatus according to an embodiment of the present invention will be described with reference to FIG. The molded body manufactured by the molded body manufacturing apparatus 10 of FIG. 1 is, for example, a molded body containing a drug for a transdermal patch used for drug administration. As shown in FIGS. 2 and 3, the molded body 100 described in this embodiment includes a cone-shaped protrusion 103 in which two different types of layers are stacked on a surface 102 of a plate-like substrate 101. Has a shape in which a plurality of are formed. The substrate 101 is a member having good air permeability, for example, a porous member. In FIG. 3, the partial area Ar1 of FIG. 2 is shown enlarged. The cone-shaped protrusion 103 differs in composition and / or property between the tip portion 104 and the base portion 105. Thus, in order to realize the two-layer configuration of the tip portion 104 and the base portion 105, the manufacturing apparatus 10 has a function of applying two types of raw material liquids. A laminated film 106 having the same composition as the base portion 105 is formed on the surface 102 of the substrate 101.
The molded body manufacturing apparatus 10 includes an isolator 11 that keeps an internal working space in a sterile state, and an isolator front chamber 12 and an isolator rear chamber 13 that are provided before and after the isolator 11. For example, the isolator 11 can maintain the atmosphere of the work space 11a aseptically at a temperature of 25 ° C. and a humidity of 70%. The isolator front chamber 12 and the isolator rear chamber 13 are decontamination pass boxes that communicate with the isolator 11 from the outside, for example, and have a function of sterilizing the

internal spaces

12a and 13a.

(1-1) Isolator front chamber 12
The isolator front chamber 12 is configured to be openable to the outside, and a front chamber magazine 14 that can store a plurality of molds 80 can be mounted in the open internal space 12a of the isolator front chamber 12. The plurality of molds 80 housed in the isolator front chamber 12 are sterilized together with the front chamber magazine 14 with the internal space 12a of the isolator front chamber 12 sealed against the outside and the isolator 11. When the isolator front chamber 12 is open to the outside, the passage 12b connected from the isolator front chamber 12 to the isolator 11 is blocked.
The mold 80 accommodated in the front chamber magazine 14 mounted in the isolator front chamber 12 can be moved to the mold supply magazine 20 in the work space 11 a of the isolator 11. When the front chamber magazine 14 moves from the isolator front chamber 12 to the isolator 11, the isolator front chamber 12 is blocked from the external space, and the passage 12 b between the isolator front chamber 12 and the isolator 11 communicates.

(1-2) Isolator 11
The isolator 11 includes

belt conveyors

21 and 27, a first dispenser 22, a filling unit 23, a first drying magazine 24, a second dispenser 25, a substrate, as well as the above-described mold supply magazine 20. A pressure mounting device 26 and a second drying magazine 28 are provided.
The mold 80 moved to the mold supply magazine 20 of the isolator 11 is placed on the belt conveyor 21 by a loader (not shown). The belt conveyor 21 conveys the mold 80 to the first dispenser 22 to the dispensing position P1 (see FIG. 5) and automatically stops.

The first dispenser 22 discharges a predetermined amount of the first raw material liquid 91 containing a chemical substance to be introduced into the human body onto the surface of the mold 80 (see FIG. 6A).
The mold 80 coated with the first raw material liquid 91 is automatically conveyed to the filling unit 23 by the belt conveyor 21. In the filling unit 23, the first raw material liquid 91 is sufficiently filled into the concave portion of the mold 80 by the blade 31 (see FIGS. 6B and 6C). However, since almost all of the first raw material liquid on the surface of the mold 80 is scraped off by the blade 31, the first raw material liquid 91 hardly remains on the surface of the mold 80.
The mold 80 in which the concave portion is filled with the first raw material liquid 91 is automatically transported to the vicinity of the first drying magazine 24 by the belt conveyor 21 and, for example, the first drying magazine by an unloader (not shown). 24. Then, the first stock in the first drying magazine 24 is sequentially taken out, and is automatically placed on the next second dispenser 25 by, for example, a loader (not shown). While being stocked in the first drying magazine 24, the first raw material liquid 91 filled in the recesses of the mold 80 is dried. As can be seen from a comparison between FIG. 6C and FIG. 7A, the volume of the first raw material liquid 91 decreases when it is dried.

The second dispenser 25 discharges a predetermined amount of a second raw material liquid 92 containing a chemical substance to be introduced into the human body onto the surface of the mold 80 (see FIG. 7A).
The mold 80 to which the second raw material liquid 92 is applied is automatically conveyed from the second dispenser 25 to the substrate pressure mounting apparatus 26 by, for example, the belt conveyor 27. In the substrate pressing and mounting apparatus 26, the substrate 101 is pressed and brought into close contact with the second raw material liquid 92 before drying on the second raw material liquid 92 discharged onto the surface of the mold 80 by, for example, a robot arm (see FIG. (Refer FIG.7 (b)).
In a state in which the substrate 101 is mounted, the mold 80 is automatically conveyed from the substrate pressure mounting device 26 to the vicinity of the second drying magazine 28 by the belt conveyor 27, and is secondly transferred by, for example, an unloader (not shown). Are stored in the drying magazine 28. The second drying magazine 28 is disposed in the dry stock area 11 b of the isolator 11 that is isolated from the area up to the substrate pressure mounting device 26. The dry stock area 11b is maintained at a higher temperature and lower humidity than the work space 11a of the isolator 11 in order to promote drying.

(1-2-1) Steps in Isolator 11 The above-described isolator 11 and the subsequent manufacturing steps are summarized as shown in FIG.
First, in step S 1, the mold 80 is set in the first dispenser 22 using the belt conveyor 27. In the first supply process (step S 2), the first raw material liquid 91 is supplied to the mold 80 by the first dispenser 22. The next step S3 includes the blade replacement step of step S3-1 and the step of filling the recess with the blade of step S3-2. These steps S3-1 and S3-2 will be described in detail later. In the subsequent drying step (step S4), the mold 80 in which the concave portion is filled with the first raw material liquid 91 is dried in the first raw material liquid 91 while being stored in the first drying magazine 24. Done. In step S 5, the mold 80 from which the first raw material liquid 91 in the recess is dried is set in the second dispenser 25 by the belt conveyor 27. In the second supply process (step S 6), the second raw material liquid 92 is supplied to the mold 80 by the second dispenser 25. In step S 7, the substrate 101 is pressed onto the second raw material liquid 92. In step S 8, the second raw material liquid 92 is dried while the mold 80 on which the second raw material liquid 92 is discharged onto the surface is stored in the second drying magazine 28. Step S9 after drying is a process after the rear chamber magazine 15 is taken out from the isolator rear chamber 13, and the molded body formed in the mold 80 is punched and the molded body is packaged. Is called.

(1-3) Isolator rear chamber 13
The isolator rear chamber 13 is configured to be openable to the outside, and the rear chamber magazine 15 can be taken out from the internal space 13 a of the opened isolator rear chamber 13. The rear chamber magazine 15 can accommodate the mold 80 moved from the second drying magazine 28 in the drying stock area 11 b of the isolator 11 to the isolator rear chamber 13. When the mold 80 moves from the isolator 11 to the isolator rear chamber 13, the passage 13 b connected from the isolator 11 to the isolator rear chamber 13 communicates, and the isolator rear chamber 13 is sealed off from the external space. When the isolator rear chamber 13 is released to the outside, the passage 13b connected from the isolator rear chamber 13 to the isolator 11 is sealed. After the isolator rear chamber 13 is opened to the outside, sterilization is performed.

(1-4) Processing in the latter stage of the isolator rear chamber 13 The rear chamber magazine 15 taken out from the isolator rear chamber 13 contains a molded body fitted in the mold 80. For example, the rear chamber magazine 15 in which the molded body is stored can be sealed in a hygienic state (for example, aseptic) and distributed as a product. Further, by performing the above-described step S9, the molded body is removed from the mold 80, and the molded body is packaged in a sanitary state (for example, aseptic condition) or the molded body is assembled with other members. After that, it can be packaged in a sanitary state (for example, aseptic), and the molded product in the packaged state can be distributed as a product. Further, an assembly in which the mold 80 is used as a part of the packaging member and is packaged in a hygienic state (for example, aseptic) while being fitted to the mold 80, or the molded body is combined with other members while being fitted to the mold 80. It is possible to wrap the product in a sanitary state (for example, aseptic condition) and to distribute the packaged molded product 80 and the mold 80 as a product.
Although not shown in FIG. 1, in order to maintain a hygienic state after the isolator rear chamber 13, for example, the machine is also operated in the clean room after the isolator rear chamber 13 or after the isolator rear chamber 13. The work is continued in a hygienic environment, such as by connecting another isolator to the subsequent stage.

(2) Mold 80
The mold 80 may be formed of a sanitary material that is not exposed to the raw material liquid, but can be formed of, for example, plastic, ceramic, or metal. Examples of the plastic forming the mold 80 include polyethylene or polypropylene, and examples of the metal forming the mold 80 include stainless steel. In the concave portion of the mold 80, for example, a conical or pyramidal space having a circular, polygonal, and elliptical cross-sectional shape is formed.

(3) Raw material liquid The first raw material liquid 91 is obtained by dissolving solid raw materials in, for example, water, a mixed solution of water and alcohol, or another solvent. Solid raw materials are polymer substances that are harmless to the human body, and include, for example, resins that are harmless to the human body, polysaccharides that are harmless to the human body, proteins that are harmless to the human body, and compounds derived therefrom that are harmless to the human body. The first raw material liquid 91 is obtained by, for example, dissolving at least one of water-soluble polysaccharides, water-soluble proteins, polyvinyl alcohol, carboxyvinyl polymer, and sodium polyacrylate in water. An example of the water-soluble polysaccharide is sodium chondroitin sulfate, and an example of the water-soluble protein is serum albumin. Examples of the chemical substance to be introduced into the human body include biologically active substances used for the purpose of treatment, diagnosis and prevention of wounds. Examples of such biologically active substances include insulin and growth hormone.
The second raw material liquid 92 is different from the first raw material liquid 91 in at least one of the kind of chemical substance, the content of the chemical substance, the solid raw material, and the solvent. Thus, by making the first raw material liquid 91 and the second raw material liquid 92 different from each other, the cone-shaped protrusion 103 changes the composition and / or properties of the tip portion 104 and the base portion 105. For example, the composition of the tip portion 104 and the base portion 105 differs depending on at least one of the kind of chemical substance, the content of the chemical substance, and the solid raw material. Also, for example, by changing the state after drying by changing the solvent and the drying method, for example, by making the solubility different, even if the tip portion 104 and the base portion 105 have the same composition, they have different properties. be able to.

(4) Filling unit 23
A specific configuration example of the filling unit 23 will be described with reference to FIG. A thick arrow shown in FIG. 5 indicates the moving direction of the blade 31.
The filling unit 23 includes a blade stocker 30, a plurality of blades 31 stocked in the blade stocker 30, an attachment mechanism 32, a blade gripping mechanism 33, a moving mechanism 34, a removal mechanism 35, and a collection box 36. Is installed.

(4-1) Blade stocker 30
The blade stocker 30 is a device for storing a plurality of blades 31 at a predetermined stock position P10. The blade stocker 30 shown in FIG. 4 has guide frames 30a that come into contact with the four corners of a plurality of blades 31 that are horizontally stacked. The blade 31 has a rectangular shape in plan view, and has a wedge-shaped cross section with a thickness decreasing toward one of the long sides. One side of the thinner side is the cutting edge of the blade 31. The four guide frames 30a extend vertically upward. The blades 31 are conveyed by the attachment mechanism 32 in order from the one mounted on the uppermost stage of the blade stocker 30. When the blades 31 are taken out from the blade stocker 30, the attachment mechanism 32 temporarily moves vertically upward along the guide frame 30a. Lifted.

(4-2) Attachment Mechanism 32 The attachment mechanism 32 includes two suction cups 32a made of rubber, for example, hemispherical. These suction disks 32a are configured to be able to be sucked onto the upper surface of the blade 31 by making the inside vacuum. By the way, since the attachment mechanism 32 has a function of aligning the positions of the two suction disks 32a with the stock position P10, the suction disk 32a can always convey a predetermined portion of the upper surface of the blade 31 by vacuum suction. The attachment mechanism 32 is moved vertically upward from the blade stocker 30 by a predetermined distance, and then moves the blade 31 in the horizontal direction to wait for a predetermined position at the slit 33a of the blade gripping mechanism 33 (see FIG. 6B). ).

(4-3) Blade gripping mechanism 33
The blade gripping mechanism 33 is, for example, a plastic rectangular parallelepiped rod-shaped member having elasticity. The slit 33a of the blade gripping mechanism 33 crosses one surface of the rectangular parallelepiped along the longitudinal direction, and the depth from the one surface is constant. Therefore, when the blade 31 having a rectangular shape in plan view is brought into contact with the deepest portion of the slit 33a, the distance from the blade edge of the blade 31 to one surface of the blade gripping mechanism 33 crossed by the slit 33a is at an arbitrary position of the blade edge. It becomes constant. That is, the shape of the blade 31 protruding from the blade gripping mechanism 33 is also rectangular in plan view.
For example, rubber (not shown) with a constant thickness is attached to the surface of the blade gripping mechanism 33 facing the slit 33a. When the blade 31 is inserted into such a slit 33a, the blade 31 is gripped by being sandwiched between rubbers on the opposing surface. Alternatively, the blade gripping mechanism 33 uses, for example, a material that is easily elastically deformed even when the above-described rubber is not attached, and the blade gripping mechanism 33 is elastically deformed when the blade 31 is inserted into the slit 33a. By configuring so, the blade 31 can be sandwiched and held between the opposing surfaces of the slit 33a. Note that a force that a finger 34a of a robot arm, which is an example of a moving mechanism 34 described later, grips the blade gripping mechanism 33 may be used as an auxiliary force that the blade gripping mechanism 33 grips and holds the blade 31.

(4-4) Moving mechanism 34
The moving mechanism 34 is composed of, for example, an articulated robot arm having a finger 34a for gripping the blade gripping mechanism 33 at the tip. The moving mechanism 34 performs the following operations (a) to (d).
(A) The blade gripping mechanism 33 is moved so that the surface facing the slit 33a of the blade gripping mechanism 33 is horizontal, and a slit 33a is formed on the blade 31 that is horizontally stacked on the blade stocker 30. The blade gripping mechanism 33 is fixed with the surface facing.
(B) In cooperation with the attachment mechanism 32, the blade 31 is inserted into the slit 33a, and the blade 31 is pushed in until the blade 31 contacts the deepest portion of the slit 33a.
(C) The blade 31 is moved horizontally along the surface 81 of the mold 80 while maintaining a predetermined angle θ (see FIG. 7C) with respect to the surface of the mold 80. This angle θ is an acute angle. During the horizontal movement of the blade 31, the blade 31 moves while the vertical cross section cut along the traveling direction is inclined with respect to the traveling direction and contacts the first raw material liquid 91. As a result, the first raw material liquid 91 is pushed and filled into the plurality of recesses 82 (see FIG. 6) by the blade 31. During the horizontal movement described above, the blade 31 is brought into contact with the surface 81 of the mold 80, but when it is desired to form a composition obtained by drying the first raw material liquid 91 on the surface 102 of the molded body 100, the blade 31 is moved to the surface of the mold 80. In some cases, the surface 81 is not contacted. In FIG. 5, it is described that the circle indicating the first raw material liquid 91 is simply expanded by the blade 31, but these circles are formed in a plurality of recesses in a region surrounded by the circle. The raw material liquid 91 is filled, and a state in which the first raw material liquid 91 does not remain on the surface around the recess is schematically shown.
(D) In order to fill the first raw material liquid 91, the blade holding mechanism 33 is moved horizontally by a predetermined distance horizontally as described in (c), and then the blade 31 is moved upward so as to be separated from the surface of the mold 80. Move to. After separating the blade 31 from the mold 80, the blade gripping mechanism 33 is moved above the collection box 36.

(4-5) Removal mechanism 35
The removal mechanism 35 includes two suction discs 35a made of rubber, for example, hemispherical. These suction plates 35a are configured to be able to be sucked onto the surface of the blade 31 by making the inside a vacuum state. By the way, the removal mechanism 35 has a function of aligning the positions of the two suction disks 32a with the blade 31 positioned directly above the collection box 36. The removal mechanism 35 vacuum-sucks the surface of the blade 31 with these suction plates 35a and pulls the blade 31 downward from the blade gripping mechanism 33 in cooperation with the moving mechanism 34. The removal mechanism 35 stops the suction by the suction disk 35 a and puts the extracted blade 31 into the collection box 36.

(4-6) Supply of Mold 80 to Filling Unit 23 The first dispenser 22 is arranged in the front stage of the filling unit 23. The belt conveyor 21 operates intermittently. When the belt conveyor 21 is stopped, the mold 80 placed on the belt conveyor 21 from the mold supply magazine 20 (see FIG. 1) is transported during the next operation of the belt conveyor 21 and is stored in the first dispenser 22. Set to dispense position P1. When the belt conveyor 21 stops and the die 80 is at the dispensing position P1, the first dispenser 22 discharges the surface of the die 80. The mold 80 is configured such that four molded bodies 100 (see FIG. 2) can be molded at a time. Accordingly, by moving the head 22 a of the first dispenser 22, the first raw material liquid 91 is discharged to four locations on the surface of one mold 80.
When the discharge by the first dispenser 22 is completed, the belt conveyor 21 is operated, and the mold 80 is carried from the dispensing position P1 to the filling position P2. At the same time, the blade 31 to which the first raw material liquid 91 is attached is removed by the removal mechanism 35, the new blade 31 is attached to the blade gripping mechanism 33 by the attachment mechanism 32, and the blade 31 is exchanged (step). S3-1).
When the belt conveyor 21 is stopped and the mold 80 is at the filling position P2, the blade gripping mechanism 33 is moved along the mold 80 by the moving mechanism 34 to fill the first raw material liquid 91 (step S3-2). ).
The mold 80 filled with the first raw material liquid 91 is transported from the filling position P2 toward the first drying magazine 24 when the belt conveyor 21 is operated next time.

(5) First drying magazine 24 and second drying magazine 28
The first drying magazine 24 is a drying device for drying the first raw material liquid 91 (see FIG. 6C) filled in the plurality of concave portions 82 of the mold 80. Further, the second drying magazine 28 uses the second raw material liquid 92 applied to the surface 81 of the mold 80 and the second raw material liquid 92 filled in the plurality of recesses 82 (see FIG. 7C). It is a drying device for drying. For example, 50 molds 80 can be stocked in the first drying magazine 24 and the second drying magazine 28. For example, the first raw material liquid 91 in the recess 82 is blown into a gap provided between the molds 80 by a fan (not shown) and stocked in the first drying magazine 24. The second raw material liquid 92 in the recess 82 is sufficiently dried during the period of being sufficiently dried and stocked in the second drying magazine 28.

(6) Second dispenser 25
7A, in the first drying magazine 24, the second raw material liquid 92 is applied to the surface 81 of the dried mold 80 of the first raw material liquid 91 in the plurality of recesses 82. As shown in FIG. Is discharged. For example, the second raw material liquid 92 is discharged toward the center of the region where the plurality of recesses 82 are formed. The discharged second raw material liquid 92 spreads on the surface 81 of the mold 80 in a short time, and forms a film 92 a on the surface 81.

(7) Substrate pressure mounting device 26
As shown in FIG. 7B, the board pressurizing and mounting apparatus 26 is composed of, for example, an articulated robot arm having a finger 26a for gripping the board 101 at the tip. The finger 26a grips the upper part of the substrate 101, and the second raw material liquid 92 does not adhere to the finger 26a when the substrate 101 is pressed against the second raw material liquid 92.

In addition, when the blade gripping mechanism 33 is moved horizontally, the first raw material liquid 91 because the angle between the blade 31 and the surface 81 of the mold 80 is an acute angle (0 <θ <90) is contained in the recess 82. It is easy to be filled.
In the above embodiment, the blade stocker 30, the attachment mechanism 32, the removal mechanism 35, and the collection box 36 constitute the blade replacement mechanism 40. The attachment mechanism 32 transports and attaches the blade 31 from the blade stocker 30 to the blade gripping mechanism 33, and the removal mechanism 35 removes the blade 31 from the blade gripping mechanism 33 and puts it in the collection box 36. Before the operation of filling one raw material liquid 91, the blade 31 to which the first raw material liquid 91 is attached can be removed, and the blade 31 to which the first raw material liquid 91 is not attached can be attached.
From the viewpoint of the manufacturing method, before the operation of moving the blade gripping mechanism 33 in the filling step (step S3-2) and filling the plurality of concave portions 82 of the mold 80 with the first raw material liquid 91, Through the blade replacement process (step S3-1), a new blade 31 to which the first raw material liquid 91 is not attached is attached to the blade gripping mechanism 33 in place of the blade 31 to which the first raw material liquid 91 is attached. .

As a result, the sanitary blade 31 to which the first raw material liquid 91 is not attached is always used to manufacture the concave portion 82 of the mold 80 with the first raw material liquid 91. In the molded body manufacturing apparatus 10 or the molded body manufacturing method shown in FIG. 4, it is easy to ensure a high sanitary condition for manufacturing the molded body 100 having the plurality of protrusions 103 inside the isolator 11.
