Furthermore, the second molded body S5 can also be the final product. Hereinafter, each part of the molded body manufacturing apparatus 100 and each step of the molded body manufacturing method will be described in detail.

[0025] (Material M1)

[0026] First, let's describe material M1. Material M1 comprises fibers F and a bonding material P that binds the fibers F together.

[0027] As for fiber F, it is not specifically limited; for example, various natural fibers and various chemical fibers can be listed.

[0028] Although the average fiber length of fiber F is not particularly limited, it is preferably 0.1 mm or more and 10 mm or less, and more preferably 1 mm or more and 5 mm or less. As a result, the strength of the second molded body S5 can be improved more reliably, and the forming, bending and cutting of the recess 201 described later can be performed easily.

[0029] From the same point of view, although the average width (average diameter) of fiber F is not particularly limited, it is preferably 0.5 μm or more and 200 μm or less, and more preferably 1.0 μm or more and 100 μm or less.

[0030] From the same point of view, the content of fiber F in material M1 is not particularly limited, for example, preferably 20% by weight or more and 99% by weight or less, more preferably 50% by weight or more and 90% by weight or less.

[0031] Combined with material P, such as various polyolefins, acrylic resins, polyvinyl chloride, polyester, polyamide and other thermoplastic resins, various thermoplastic elastomers, starch, dextrin, glycogen, amylose, hyaluronic acid, kudzu root, konjac, potato starch, etherified starch, esterified starch, natural gum paste, fiber-induced paste, seaweed, animal protein and other components derived from natural sources, one or more of these substances can be selected and used in combination.

[0032] The bonding material P is in the form of particles or fibers.

[0033] When the bonding material P is in the form of particles, its average particle size (volume basis) is not particularly limited. For example, it is preferably 0.5 μm or more and 200 μm or less, and more preferably 1.0 μm or more and 100 μm or less. As a result, the strength of the second molded body S5 can be improved more reliably, and the forming, bending and cutting of the recess 201 described later can be performed easily.

[0034] From the same point of view, when the bonding material P is fibrous, the average fiber length of the bonding material P is not particularly limited. For example, it is preferably 0.1 mm or more and 10 mm or less, and more preferably 1 mm or more and 10 mm or less.

[0035] From the same perspective, when the bonding material P is fibrous, the average width (average diameter) of the bonding material P is not particularly limited. For example, it is preferably 0.5 μm or more and 200 μm or less, and more preferably 1.0 μm or more and 100 μm or less. As a result, the strength of the second molded body S5 can be improved more effectively.

[0036] From the same perspective, the content of the bonding material P in material M1 is not particularly limited, but is preferably 1% by weight or more and 80% by weight or less, more preferably 10% by weight or more and 50% by weight or less. This allows for a more effective increase in the strength of the second molded body S5.

[0037] In addition, material M1 may also contain other components besides binding material P. Examples of such other components include colorants for coloring fibers, aggregation inhibitors for inhibiting fiber aggregation, and flame retardants for making fibers less flammable. One or more of these components may be used.

[0038] When material M1 contains other components, the content of these other components in material M1 is not particularly limited, but is preferably 0.1% by weight or more and 10% by weight or less, more preferably 0.5% by weight or more and 5% by weight or less. This allows for the achievement of the effects produced by mixing other components, and ensures sufficient amounts of fiber F and binding material P, thereby more effectively improving the strength of the second molded article S5. Furthermore, if the fiber F itself dissolves or softens and the fibers F bond together, then the binding material P may not need to be added in addition to the fiber F.

[0039] (Stacking Section 1, Stacking Process)

[0040] like Figure 1 As shown, the stacking section 1 is the part that performs the stacking process, dispersing material M1 in gas to generate a deposit M2 of material M1. Figure 1 As shown, the stacking section 1 has a dispersing section 11, a mesh belt 12, a suction section 13, and a sheet supply section 14.

[0041] The dispersing section 11 unravels and releases the intertwined fibers F in the material M1. The dispersing section 11 has a roller 111 for introducing and releasing the material M1 and a housing 112 for receiving the roller 111.

[0042] The drum 111 is composed of a cylindrical mesh and is a sieve that rotates around its central axis. As the drum 111 rotates, fibers F and the like, smaller than the mesh size in the material M1, can pass through it. At this time, the material M1 is released along with the air. In other words, the drum 111 functions as a release unit for releasing material M1 containing fibers F.

[0043] The roller 111 is connected to a drive source (not shown) and rotates by a rotational force output from the drive source. This drive source is electrically connected to a control device 7, and its operation is controlled.

[0044] Furthermore, the material M1 released by the roller 111 falls as it disperses in the gas and moves toward the mesh belt 12 located below the roller 111.

[0045] In addition, a material supply unit (not shown) is connected to the roller 111. Examples of material supply units include those in the sheet manufacturing apparatus described in Japanese Patent Application Publication No. 2024-113315, which have a structure including a raw material supply unit, a coarse crushing unit, a defiberizing unit, and a mixing unit, or a supply unit that supplies material M1 in a box-like manner.

[0046] The mesh belt 12 is a mesh component, and in the illustrated structure, it is composed of annular belts. Sheets S are supplied to the mesh belt 12 from the sheet supply section 14 (described later), and material M1 dispersed and released by the dispersion section 11 accumulates on the sheet S, thereby forming a deposit M2. The mesh belt 12 is wound around four tension rollers 121. Driven by the rotation of the tension rollers 121, the deposit M2 on the mesh belt 12 is conveyed downstream.

[0047] Furthermore, although the mesh belt 12, which is an annular belt, is used as an example of a mesh component in the illustrated structure, the present invention is not limited to this. For example, a structure using a flat mesh component may also be used.

[0048] The suction section 13 is a suction mechanism that draws air from below the mesh belt 12. This allows material M1 to be drawn onto the mesh belt 12. Therefore, it promotes the deposition of material M1 onto the sheet S. Furthermore, it enables the generation of a uniformly thick deposit M2.

[0049] A pipe 131 is connected to the suction section 13. Furthermore, a blower 132 is installed midway along the pipe 131. The operation of the blower 132 generates suction force within the suction section 13. The blower 132 is electrically connected to the control device 7, and its operation is controlled.

[0050] The sheet supply unit 14 has a supply roller 141, which has the function of feeding out sheet S by rotating the supply roller 141. The sheet S fed out by the supply roller 141 is fed onto the mesh belt 12. Then, a deposit M2 is formed on the sheet S. Hereinafter, the sheet S and the deposit M2 on the sheet S are collectively referred to as "one-time deposited sheet S1".

[0051] The supply roller 141 is connected to a drive source (not shown) and rotates by a rotational force output from the drive source. This drive source is electrically connected to a control device 7, and its operation is controlled.

[0052] The sheet S is breathable and is composed of woven fabric, non-woven fabric, etc. The fibers constituting the sheet S include those exemplified in the aforementioned fiber F. By supplying this sheet S, the strength of the second molded body S5 can be improved more effectively.

[0053] like Figure 3As shown, although the average thickness T of sheet S S The thickness is not particularly limited, but is preferably 0.01 mm or more and 20 mm or less, more preferably 0.1 mm or more and 2 mm or less. As a result, the strength of the second molded body S5 can be improved more reliably, and the forming, bending and cutting of the recess 201 described later can be performed easily.

[0054] From the same perspective, the density ρ of material M1 in the accumulation M2... M1 No particular limit is specified, but 0.01 g / cm³ is preferred. 3 Above and 2.0 g / cm 3 The following is more preferably 0.1 g / cm³. 3 Above and 1.0 g / cm 3 the following.

[0055] Starting from the same point of view, such as Figure 3 As shown, the average thickness T of the deposit M2 M2 There are no particular limitations, but it is preferred to be 1 mm or more and 100 mm or less, and more preferably 1.5 mm or more and 50 mm or less.

[0056] From the same perspective, the average thickness T of a single-layer stacked sheet S1 S1 It is not specifically limited, but preferably 1.1 mm or more and 120 mm or less, more preferably 1.3 mm or more and 60 mm or less.

[0057] (Fixing Part 2, Fixing Process)

[0058] like Figure 1 As shown, the fixing unit 2 performs a fixing process, fixing the pile M2 of the primary stacked sheet S1 and conveying it downstream. The fixing performed by the fixing unit 2 refers to compressing the primary stacked sheet S1, thereby reducing the thickness of the pile M2 to increase its density. By performing such fixing (temporary fixing), the fibers F can be prevented from loosening, improving operability.

[0059] The fixing part 2 has a pair of heating and pressurizing rollers 21 disposed on the downstream side of the stacking part 1. Each heating and pressurizing roller 21 is arranged vertically across the conveying path of the primary stacked sheet S1. When the primary stacked sheet S1 passes between the pair of heating and pressurizing rollers 21, the stacked material M2 is heated and pressurized. As a result, a secondary stacked sheet S2 is generated. Then, the secondary stacked sheet S2 is conveyed downstream by means of the rotation of the pair of heating and pressurizing rollers 21.

[0060] A pair of heated pressure rollers 21 are connected to a drive source (not shown) and a heat source, and rotate by the rotational force output from the drive source. The heated pressure rollers 21 are heated by the heat generated by the heat source. The drive source and the heat source are electrically connected to a control device 7, and their operation is controlled.

[0061] By applying pressure and heating simultaneously through the fixing part 2, the bonding material P in the stack M2 can be melted or softened and penetrated between the fibers F. Therefore, the fibers F can be bonded together, restricting accidental movement of the fibers F in the secondary stacked sheet S2, thus facilitating shape maintenance. This improves operability in subsequent processes.

[0062] like Figure 3 As shown, the average thickness T of the secondary stacked sheet S2 S2 While not specifically limited, the thickness is preferably 0.8 mm or more and 100 mm or less, more preferably 1.2 mm or more and 50 mm or less. This improves operability in subsequent processes more effectively.

[0063] The average thickness T of the secondary stacked sheet S2 S2 The average thickness T of the sheet S1 stacked in one step S1 The ratio of T S2 / T S1 The pressure is not particularly limited, but is preferably 0.1 or more and 0.9 or less, more preferably 0.2 or more and 0.8 or less. Applying this level of pressure through the fixing part 2 can more effectively improve operability in subsequent processes.

[0064] The density ρ of material M1 in the secondary stacked sheet S2 S2 It is not specifically limited, but is preferably 0.02 g / cm³. 3 Above and 3.0 g / cm 3 The following is more preferably 0.15 g / cm³. 3 Above and 1.5g / cm 3 The following applies pressure by means of the fixing part 2, which can more effectively improve operability in subsequent processes.

[0065] Although the density ρ of the material M1 in the accumulation M2 is M1 The density ρ of material M1 in the secondary stacked sheet S2 S2 The ratio ρ M1 / ρ S2 The pressure is not specifically limited, but it is preferably 0.1 or more and 0.9 or less, more preferably 0.2 or more and 0.8 or less. Applying this level of pressure through the fixing part 2 can more effectively improve the operability in subsequent processes.

[0066] The heating temperature T2 of the fixing part 2 is not particularly limited, but is preferably 30°C or higher and 200°C or lower, and more preferably 35°C or higher and 150°C or lower. This allows the bonding material P in the deposit M2 to be melted or softened more effectively.

[0067] The fixing part 2 may only be pressurized. That is, in the fixing process, only pressurization may be performed. Alternatively, the fixing part 2 may be omitted. That is, in the method for manufacturing the molded body of the present invention, the fixing process may be omitted.

[0068] (Cutting section, cutting process)

[0069] like Figure 1 As shown, the cutting section 3 performs a cutting process to cut the secondary stacked sheet S2 into the desired size. The cutting section 3 has a pair of cutting blades 31 located downstream of the fixing section 2. Each cutting blade 31 is arranged vertically across the conveying path of the secondary stacked sheet S2. Each cutting blade 31 is arranged with its blade tips facing each other, configured so that the blade tips can approach and separate. When the blade tips of each cutting blade 31 approach to contact, the secondary stacked sheet S2 passing between them is cut. In addition, by adjusting the timing of the approach and separation of each cutting blade 31, the length of the secondary stacked sheet S2 can be adjusted.

[0070] The cutting blade 31 is connected to a drive source (not shown) and approaches and separates by means of a force output from the drive source. This drive source is electrically connected to a control device 7, whose operation is controlled.

[0071] Furthermore, a pair of conveying rollers 32 are provided downstream of the cutting blade 31. They are arranged vertically across the conveying path of the secondary stacked sheet S2. The conveying rollers 32 rotate while clamping the cut secondary stacked sheet S2, thereby conveying it downstream to the first forming section 4.

[0072] The conveyor roller 32 is connected to a drive source (not shown) and rotates by means of a rotational force output from the drive source. This drive source is electrically connected to a control device 7, and its operation is controlled.

[0073] In addition, the cutting part 3 is not limited to the above structure, and may also have a structure in which a cutting roller with a blade is formed on the outer periphery of the roller instead of the cutting blade 31.

[0074] In addition, although not shown in the figure, the cutting part 3 may also have a cutting blade that cuts the two edges of the secondary stacked sheet S2 in the width direction.

[0075] Alternatively, the cutting section 3 can be omitted. In this case, it is preferable to use a structure in which the secondary stacked sheet S2 is bent and overlapped in the thickness direction before forming in the first forming section 4 described later.

[0076] (First forming section 4, first forming process)

[0077] like Figure 1As shown, the first forming part 4 is the part that performs the first forming process as follows: the secondary stacked sheet S2 is heated and pressurized by the pressurizing part 41 to generate a first shaped body S3 with pattern 200.

[0078] The pressurizing section 41 has a block-shaped pressurizing member 411 and a pressurizing member 412 as a pressurizing mechanism. The pressurizing member 411 and the pressurizing member 412 are metal molds, but are not limited to this, and may also be molds made of ceramic or the like. A plurality of secondary stacked sheets S2 are stacked on the pressurizing member 411. The pressurizing member 412 is connected to a drive source (not shown) and is configured to be able to approach and separate relative to the pressurizing member 411. When the pressurizing member 412 approaches the pressurizing member 411, the secondary stacked sheets S2 on the pressurizing member 411 are clamped by the pressurizing member 411 and the pressurizing member 412, and heated and pressurized to form a first molded body S3. When the pressurization is released, the secondary stacked sheets S2 can be placed on the pressurizing member 411, or the first molded body S3 can be removed from the pressurizing member 411.

[0079] The pressure components 411 and 412 are not limited to being block-shaped; for example, they can also be made of rollers.

[0080] The surface of the pressure member 411 on the side where the secondary stacked sheet S2 is disposed is flat. The surface of the pressure member 412 on the side where the secondary stacked sheet S2 is disposed has irregularities. The shape of these irregularities corresponds to the pattern to be formed on the surface of the first molded body S3. Alternatively, the irregularities can be formed on the surface of the pressure member 411, while the surface of the pressure member 412 can be flat. The irregularities can also be formed on the surfaces of both the pressure member 411 and the pressure member 412.

[0081] Furthermore, the pressurizing component 411 is connected to a heat source (not shown) and can be heated by the heat generated by the heat source. The aforementioned drive source and heat source are electrically connected to the control device 7 to control the pressurization timing, heating timing, pressurization level, and heating level. Additionally, the pressurizing component 412 can be connected to a heat source, or only the pressurizing component 412 can be connected to a heat source. If the heat source is connected only to the pressurizing component 411 without the protrusion 413, the heat source does not need to be connected to the pressurizing component 412 with the protrusion 413, thus making the manufacture of the pressurizing component 412 easier. Furthermore, when multiple pressurizing components 412 with different protrusion 413 shapes are prepared and selected for use, their replacement can be easily performed.

[0082] Furthermore, by applying pressure and heating simultaneously through the first forming section 4, the bonding material P in the secondary stacked sheets S2 can be melted or softened and penetrated between the fibers F. Therefore, the fibers F can be bonded together to improve the strength of the first formed body S3, and the stacked adjacent secondary stacked sheets S2 can be well bonded together.

[0083] Furthermore, as the fibers F bond together, the unevenness of the surface of the pressure member 412 is transferred, thereby enabling the formation of a desired pattern on the surface of the first molded body S3.

[0084] In the first forming section 4, multiple secondary stacked sheets S2 are pressed in an overlapping state to form a product as shown in the figure. Figure 4 The first molded body S3 is shown. While the number of secondary stacked sheets S2 laminated on the pressure member 411 is not particularly limited, it is preferably 2 or more and 20 or less, more preferably 3 or more and 10 or less. This allows for more effective improvement in the strength of the first molded body S3 (described later) and enables good bonding between adjacent laminated secondary stacked sheets S2. Furthermore, this structure is not limited to this configuration; a structure in which one secondary stacked sheet S2 is pressurized within the first molding section 4 is also possible.

[0085] The pressurization in the first forming part 4 is carried out at a higher pressure than that in the fixing part 2, that is, the degree of compression of the fiber F is higher than that of the fiber F in the fixing part 2.

[0086] like Figure 4 As shown, the average thickness T of a secondary stacked sheet S2 of the first formed body S3 is... S3 It is not particularly limited, but preferably 0.7 mm or more and 90 mm or less, more preferably 1.1 mm or more and 40 mm or less. By applying this level of pressure through the first forming part 4, the strength of the first molded body S3 can be improved more effectively, and a deeper recess 201 can be formed more easily, thereby improving its function as pattern 200 more reliably.

[0087] The density ρ of material M1 in a secondary stacked sheet S2 of the first formed body S3 S3 It is not specifically limited, but is preferably 0.03 g / cm³. 3 Above and 4.0 g / cm 3 The following is more preferably 0.2 g / cm³. 3 Above and 2.5g / cm 3 The following applies pressure to this extent through the first forming part 4, which can more effectively improve the strength of the first formed body S3.

[0088] The density ρ of material M1 in the secondary stacked sheet S2 S2The density ρ of material M1 in a secondary stacked sheet S2 of the first formed body S3 is... S3 The ratio ρ S2 / ρ S3 It is not particularly limited, but preferably 0.2 or more and 0.8 or less, more preferably 0.3 or more and 0.7 or less. By applying this level of pressure through the first forming part 4, the strength of the first formed body S3 can be improved more effectively, and the forming, bending, and cutting of the recess 201 can be easily performed.

[0089] Although the density ρ of the material M1 in the accumulation M2 is M1 The density ρ of material M1 in a secondary stacked sheet S2 of the first formed body S3 is... S3 The ratio ρ M1 / ρ S3 It is not particularly limited, but preferably 0.05 or more and 0.7 or less, more preferably 0.1 or more and 0.5 or less. By applying this level of pressure through the first forming part 4, the strength of the first formed body S3 can be improved more effectively, and the forming, bending, and cutting of the recess 201 can be easily performed.

[0090] The heating temperature T4 in the first forming part 4 is not particularly limited, but is preferably 40°C or higher and 220°C or lower, more preferably 150°C or higher and 190°C or lower. This allows for more effective melting or softening of the bonding material P, thereby enabling a more secure bond between the fibers F. Consequently, the strength of the first formed body S3 can be improved more effectively, and the formation, bending, and cutting of the recess 201 can be performed more easily.

[0091] Furthermore, the ratio T2 / T4 of the heating temperature T2 of the fixing part 2 to the heating temperature T4 of the first forming part 4 is not particularly limited, but is preferably 0.1 or more and 1.0 or less, more preferably 0.4 or more and 0.7 or less. This allows for more effective melting or softening of the bonding material P, thereby enabling a more secure bond between the fibers F. Consequently, the strength of the first formed body S3 can be improved more effectively, and the formation, bending, and cutting of the recess 201 can be performed more easily.

[0092] Furthermore, the first forming section 4 may only be pressurized. That is, in the first forming process, only pressurization may be performed.

[0093] like Figure 1As shown, a downwardly protruding protrusion 413 is provided on the lower surface (pressurizing surface) of the pressurizing member 412. When viewed from above, the protrusion 413 has a predetermined shape. When the first forming part 4 applies pressure, the protrusion 413 is embedded into the secondary deposited sheet S2. As a result, a pattern 200, i.e., a recess 201 (groove), corresponding to the shape of the protrusion 413 is formed on the upper surface of the first formed body S3. That is, the recess 201 is formed by transferring the shape of the protrusion 413. By forming the pattern 200 using this method, the pattern 200 can be formed easily and accurately.

[0094] Pattern 200 forms graphics, patterns, characters, and other designs, represented by lines, dots, and combinations thereof. Pattern 200 has the function of visually or tactilely representing the assembly position (overlapping position), which indicates the position when the third molded body S4 is overlapped on the first molded body S3 in the second molding process described later.

[0095] like Figure 4 As shown, the recess 201 is an example of the form of pattern 200, and is an assembly pattern that serves as a mark for the assembly position in the second molding process. By forming such a recess 201 simultaneously with the heating and pressurization in the first molding section 4, compared to performing the heating and pressurization process (the molding process) and the mark-adding process (e.g., the printing process) separately, one process can be omitted, and the first molded body S3 can be manufactured more efficiently. Furthermore, the productivity of the second molded body S5 can be improved.

[0096] In particular, by forming the recess 201 in the pattern 200, the overlap of the third molded body S4 with the first molded body S3 during assembly, i.e., positional shift, can be effectively prevented during the second molding process, and their alignment can be accurately performed. In addition, after assembly and before joining based on the second molded part 6, the positional shift of the third molded body S4 is restricted by the inner surface of the recess 201, which can improve the assembly accuracy of the second molded body S5.

[0097] The portion with the recess 201 has a minimum thickness T at the thickness of the first molded body S3. min The portion where the recess 201 is not formed has a maximum thickness T at the thickness of the first molded body S3. max The portion with the maximum thickness T. max With minimum thickness T min The ratio of T max / T min Preferably, the depth is 1.2 or more and 2 or less, more preferably 1.25 or more and 1.9 or less. This ensures sufficient depth of the recess 201, more effectively fulfills its function as a marker, and prevents excessive unevenness in strength, i.e., density of material M1, thus maintaining the high quality of the first molded body S3.

[0098] Furthermore, the pattern 200 is not limited to the recess 201. It can also be a structure like a slit that runs through the thickness direction of the first molded body S3, or it can be an independent recess arranged in a prescribed pattern to form the pattern 200 as a whole.

[0099] The protrusion 413 is appropriately designed according to the pattern of the desired pattern 200. In this embodiment, the protrusion 413 is composed of two elongated convex strips. In addition, the cross-sectional shape of the protrusion 413 is rectangular. Thus, the recess 201 is formed as a groove, and in the second forming process, the elongated third forming body S4 can be inserted into the recess 201.

[0100] However, it is not limited to this structure; the protrusion 413 can be one or more.

[0101] In addition, the cross-sectional shape of the protrusion 413 and the cross-sectional shape of the recess 201 are not limited to rectangles, but can also be wedge-shaped, semi-circular or other shapes.

[0102] The heating and pressurizing time for the first forming section 4 is not particularly limited, but is preferably 1 second or more and 60 seconds or less, more preferably 2 seconds or more and 40 seconds or less. This allows for more reliable formation of the pattern 200 and melting or softening of the bonding material P.

[0103] (Cooling Section 5, Cooling Process)

[0104] The cooling section 5 is the part that performs the cooling process for cooling the first molded body S3. The cooling performed by the cooling section 5 refers to lowering the temperature of the first molded body S3 immediately after the first molding process is completed. The cooled temperature only needs to be below the melting point of the bonding material P; for example, room temperature is preferred, but it is not limited to this. In this embodiment, a structure is formed in which a cooling block or cooling roller contacts both surfaces of the first molded body S3. However, it is not limited to this structure; the cooling section 5 may also be a structure that blows cold air onto the first molded body S3, or it may be a structure in which the first molded body S3 is disposed within a cavity and heat is dissipated from the first molded body S3.

[0105] By implementing such a cooling process, the bonding material P of the first molded body S3 can be solidified, thereby strengthening the bond between the fibers F. Therefore, the second molding process described later can be performed while the strength of the first molded body S3 is more effectively improved. Furthermore, the operability of the second molding process can be improved.

[0106] Furthermore, if heating is not performed in the first forming process, the cooling process can be omitted.

[0107] Alternatively, if heating is performed in a fixed process, a cooling process can be performed between the fixed process and the first forming process. In this case, the cooling process performed between the fixed process and the first forming process is the first cooling process, and the cooling process performed between the first forming process and the second forming process is the second cooling process. The cooling temperatures of the first cooling process and the second cooling process can be the same or different.

[0108] (Second forming section 6, second forming process)

[0109] The second forming unit 6 is a forming unit that performs a second forming process by processing at a position corresponding to the pattern 200 formed in the first forming process, and performs an alignment process and a joining process. That is, the second forming process includes an alignment process and a joining process.

[0110] The alignment process is a process of detecting the pattern 200 of the first molded body S3 and overlapping at least a portion (in this embodiment, all) of the pattern 200 formed in the first molding process with the position of the detected pattern 200 with the third molded body S4.

[0111] The joining process is a part of the second forming process that follows the alignment process, joining the first molded body S3 and the third molded body S4 to form the second molded body S5.

[0112] The second forming unit 6 includes a sensor (not shown), a robotic arm (not shown), and a sewing machine 61. The second forming unit 6 uses the sensor to determine the position of the pattern 200, and uses the robotic arm to overlap the third forming body S4 onto the pattern 200 determined at the position of the pattern 200. Then, the second forming unit 6 uses the sewing machine 61 to join the first forming body S3 and the third forming body S4 by sewing. The sewing method of the sewing machine 61 is not particularly limited; examples include straight sewing, zigzag sewing, blind sewing, and overlock sewing.

[0113] Alternatively, the second forming part 6 can also be a structure that performs joints other than sewing, such as pressure-based joints, heat-based joints, or joints using adhesives.

[0114] The width of the third molded body S4 is the same as the width of the recess 201. This effectively prevents positional misalignment during assembly, ensuring accurate alignment. Furthermore, by more effectively limiting the positional misalignment of the third molded body S4 after assembly and before engagement with the second molded part 6, the assembly accuracy of the second molded body S5 can be improved more reliably.

[0115] Thus, in the second molding process, the first molded body S3 and the third molded body S4 are joined while at least a portion (or all of it in the structure shown in the figure) of the third molded body S4 is inserted into the recess 201. This allows the joining to be performed with the third molded body S4 accurately aligned with the first molded body S3. Therefore, the quality of the second molded body S5 can be further improved.

[0116] Furthermore, not limited to the above structure, the width of the third molded body S4 can be either wider or narrower than the width of the recess 201.

[0117] The material of the third molded body S4 is not particularly limited. The third molded body S4 can be made of a fiber-containing material or a non-fiber-containing material, for example, by injection molding of a resin material. When the third molded body S4 is made of a fiber-containing material, it can be manufactured by a process from the aforementioned stacking process to the cooling process, in which the fiber-containing material is stacked to bond the fibers together, or it can be manufactured by other methods. As the fiber or bonding material P of the third molded body S4, the material exemplified as a constituent material of material M1 can be used.

[0118] Alternatively, the first molded body S3 and the third molded body S4 can be integrated as one piece. Although not shown, by overlapping and partially joining the folded-back, integrated first molded body S3, a second molded body S5 as a bag is obtained. In this case, a portion of the first molded body S3 can be considered as the third molded body S4. Then, the rope-like third molded body S4, which will become a handle, is overlapped onto the bag and partially joined, thereby obtaining the second molded body S5 as a tote bag.

[0119] (Control device 7)

[0120] Each part of the molding body manufacturing apparatus 100 is electrically connected to the control device 7. Furthermore, the operation of these parts is controlled by the control device 7.

[0121] like Figure 1 As shown, the control device 7 includes a control unit 71, a storage unit 72, and a communication unit 73.

[0122] The control unit 71 has at least one processor that executes various programs stored in the storage unit 72. For example, a CPU (Central Processing Unit) can be used as the processor. Furthermore, the control unit 71 has various functions, such as controlling the driving of various parts of the apparatus related to the manufacturing of the molded body.

[0123] The storage unit 72 may store, for example, a program for executing the manufacturing method of the molded body according to the present invention. Alternatively, the program for executing the manufacturing method of the molded body according to the present invention may be stored in a storage device other than the storage unit 72, such as a server's storage device or an external storage device that can be attached to or detached from the control device 7.

[0124] The communication unit 73, for example, is composed of an I / O interface, and communicates with various parts of the molding apparatus 100. Additionally, the communication unit 73, for example, has the function of communicating with a computer or server (not shown) via a network.

[0125] The control device 7 can be either built into the molding body manufacturing apparatus 100 or installed in an external device such as a computer. Furthermore, the control unit 71 and the storage unit 72 can be integrated into a single unit, or the control unit 71 can be built into the molding body manufacturing apparatus 100 while the storage unit 72 is installed in an external device such as a computer, or the storage unit 72 can be built into the molding body manufacturing apparatus 100 while the control unit 71 is installed in an external device such as a computer.

[0126] As explained above, the method for manufacturing the molded body of the present invention comprises: a first molding step in which a material M1 containing fibers F is pressed by a pressing part 41, which serves as a pressing mechanism, thereby transferring a pattern 200 and bonding the fibers F together to form a first molded body S3; and a second molding step in which processing is performed at positions corresponding to the pattern 200 formed by the first molding step to form a second molded body S5. Thus, in the first molding step, the pressing of the first molded body S3 and the formation of the pattern 200 (in this embodiment, the recess 201) can be performed simultaneously. Therefore, the first molded body S3 can be manufactured efficiently. As a result, the productivity of the second molded body S5 can be improved.

[0127] Furthermore, the molding body manufacturing apparatus 100 includes: a pressure unit 41, which acts as a pressure mechanism, pressurizes a material M1 containing fibers F to generate a first molded body S3 having a pattern 200 and formed by the fibers F bonded together; and a second molding unit 6, which acts as a molding unit, and processes at positions corresponding to the pattern 200 formed by the pressure unit 41 to generate a second molded body S5. Thus, the first molding unit 4 can simultaneously perform the pressing of the first molded body S3 and the formation of the pattern 200 (recess 201 in this embodiment). Therefore, the first molded body S3 can be manufactured efficiently. As a result, the productivity of the second molded body S5 can be improved.

[0128] Furthermore, as an example of "the position corresponding to the pattern 200 formed in the first molding process", this embodiment describes the case in which the second molding process is performed when the pattern 200 and the third molding body S4 are completely overlapped when viewed from above. However, the present invention is not limited to this. The second molding process can be performed as long as the pattern 200 and the third molding body S4 are at least partially overlapped. As long as the third molding body S4 is arranged along the pattern 200, they may not overlap.

[0129] In addition, in this embodiment, the alignment process and the joining process are given as examples of "processing" in the second forming process, but the present invention is not limited to these. It can be a bending process, a cutting process, or a process that combines them.

[0130] Furthermore, in this embodiment, the case of pressurizing the secondary stacked sheet S2 in the first forming process has been described, but this is not the case in the present invention. Any method can be used as long as the material M1 contains fiber F.

[0131] Furthermore, the pressure unit 41, which is a pressure mechanism, has a pressure member 412 with protrusions 413 on its surface. In the first forming process, when the secondary stacked sheet S2, which is a deposit, is pressurized, the shape of the protrusions 413 is transferred onto the first formed body S3 to form a pattern 200. As a result, the pattern 200 can be formed easily and accurately.

[0132] Furthermore, in the second molding process, with the third molded body S4 overlapping at least a portion of the pattern 200 of the first molded body S3, the first molded body S3 and the third molded body S4 are joined to form the second molded body S5. This allows for more accurate alignment of the second molded body S5 with respect to the pattern 200. Additionally, the third molded body S4 can be used to conceal at least a portion of the pattern 200, further improving design flexibility.

[0133] Furthermore, the first molded body S3 has a recess 201 formed by the shape of a transfer protrusion 413. In the second molding process, the first molded body S3 and the third molded body S4 are joined while at least a portion of the third molded body S4 is inserted into the recess 201. This allows the joining to be performed with the third molded body S4 accurately aligned with the first molded body S3. Therefore, the quality of the second molded body S5 can be further improved.

[0134] The maximum thickness T of the first shaped body max Minimum thickness T of the first shaped body min The ratio of T max / T minPreferably, the depth is 1.2 or more and 2 or less. This ensures that the depth of the recess 201 is adequately guaranteed, the function of the marking portion is more effectively performed, and excessive unevenness in strength, i.e., the density of the material M1, is prevented, thus maintaining the high quality of the first molded body S3.

[0135] The pressurizing unit 41, which serves as a pressurizing mechanism, has a pair of pressurizing members 411 and 412. The secondary stacked sheet S2, which is a deposit, is heated and pressurized between the pair of pressurizing members 411 and 412. One pressurizing member 412 has a protrusion 413 on its surface and is not heated, while the other pressurizing member 411 does not have a protrusion corresponding to the pattern and is heated. Therefore, a heat source does not need to be connected to the pressurizing member 412 with the protrusion 413, thus making it easy to manufacture the pressurizing member 411. Furthermore, when multiple pressurizing members 412 with different shapes of protrusion 413 are prepared and selected for use, their replacement can be easily performed.

[0136] In the first forming process, multiple stacked materials M2 are pressed together in an overlapping state to form a first shaped body S3. Thus, even if a single stacked material M2 is relatively thin, a first shaped body S3 with sufficient strength can be formed.

[0137] In the method for manufacturing the molded body of the present invention, a cooling step is provided after the first molding step and before the second molding step to cool the first molded body S3. This allows the second molding step to be performed while the strength of the first molded body S3 is sufficiently improved, and also enhances the operability of the second molding step.

[0138] <Second Implementation>

[0139] Figure 6 This is a cross-sectional view showing the pressure section of the molding body manufacturing apparatus according to the second embodiment of the present invention.

[0140] The following is for reference Figure 6 The second embodiment of the method for manufacturing the molded article and the apparatus for manufacturing the molded article of the present invention will be described, but the following description will focus on the differences from the first embodiment, and the same items will be omitted.

[0141] like Figure 6 As shown, the pressure member 412 omits the protrusion 413 described in the first embodiment, and its surface is flat. Furthermore, unlike the first embodiment, it incorporates a rod heater 414 as a heat source. Two rod heaters 414 are provided, arranged parallel to each other and incorporated into the pressure member 412. However, the shape of the heater is not limited to a rod heater, as long as it corresponds to the pattern to be transferred. Additionally, the heater may be exposed on the surface of the pressure member 412 or it may be concealed within the member.

[0142] The temperature of the area corresponding to the rod heater 414 in the pressure member 412 is higher than the surrounding area. Therefore, when the secondary stacked sheet S2 is pressurized, it can be locally heated. Through localized heating, the secondary stacked sheet S2 locally discolors, forming a discolored portion 202 as pattern 200 in the first molded body S3. This can also be described as transferring the pattern formed by the rod heater 414 included in the pressure member 412 through heat, or forming burn marks. Alternatively, the pressure member 411 may also be equipped with a heater, and the patterns can be transferred on both sides using the heaters of both the pressure member 411 and the pressure member 412.

[0143] The color-changing part 202 is an assembly pattern that serves as a mark indicating the position when the third molded body S4 is overlapped with the first molded body S3 in the second molding process. By forming the color-changing part 202 simultaneously with the heating and pressurization in the first molding part 4, one process can be omitted compared to performing the heating and pressurization process (the molding process) and the mark-adding process (e.g., the printing process) separately, thereby enabling efficient manufacturing of the first molded body S3. Furthermore, the productivity of the second molded body S5 can be improved.

[0144] In this structure, in addition to the effects mentioned above, the pattern 200 can be formed with a simpler structure. Furthermore, by appropriately switching whether the rod heater 414 is heated or not, it is possible to select whether to form the color-changing part 202, thus providing excellent convenience.

[0145] The pressure unit 41, acting as a pressure mechanism, applies pressure and heats the material. In the first forming process, heat causes partial discoloration of the secondary deposited sheet S2, which serves as the deposit material, thereby transferring the pattern 200 onto the first molded body S3. This allows for the efficient manufacture of the first molded body S3 with a simpler structure, improving the productivity of the second molded body S5. Furthermore, it offers superior convenience. In particular, since the discolored pattern 200 is easily visible, the process of overlapping the third molded body S4 onto the first molded body S3 can be performed more smoothly. Moreover, this discoloration can be achieved through carbonization of the deposited material by heating, through the discoloration of colorants such as leuco dyes contained in the deposited material, or through other principles.

[0146] <Third Implementation Method>

[0147] Figure 7 This is a cross-sectional view of a third molded body manufactured by the molding body manufacturing apparatus according to the third embodiment of the present invention. Figure 8 This is a flowchart of a method for manufacturing a molded body according to a third embodiment of the present invention.

[0148] The following is for reference Figure 7 as well as Figure 8 The third embodiment of the method for manufacturing the molded article and the apparatus for manufacturing the molded article of the present invention will be described, but the following description will focus on the differences from the first embodiment, and the same items will be omitted.

[0149] like Figure 7 As shown, in this embodiment, a bending pattern 203 is formed on the first molded body S3 as pattern 200. The bending pattern 203 serves as a marker indicating the bending position of the second molded body S5. The bending pattern 203 is composed of recesses (grooves) formed at positions different from the recesses 201. In the illustrated structure, they are formed between each recess 201. Although not shown, the bending pattern 203 is formed by... Figure 1 The pressure component 412 shown is formed by providing protrusions for forming bending patterns 203 between each protrusion 413 and performing a first forming process.

[0150] The bending pattern 203 and the recess 201 have different cross-sectional shapes. Therefore, the bending pattern 203 and the recess 201 can be easily distinguished visually. This allows for accurate separate joining and bending processes. However, the structure is not limited to the above. The bending pattern 203 and the recess 201 can also be the same shape.

[0151] In addition, such as Figure 8 As shown, in the manufacturing method of the molded body of this embodiment, a bending step is included as the second molding step, in which the second molded body S5 is bent according to the bending pattern 203. Therefore, the second molded body S5 can be bent and processed into a desired shape.

[0152] According to this structure, in the first forming process, in addition to the recess 201, the bending pattern 203 can also be processed simultaneously. Therefore, the first molded body S3 can be manufactured as efficiently as in the first embodiment, and the bending process can be performed quickly and accurately. As a result, a second molded body S5 with rich variations can be obtained quickly and accurately, and its productivity can be improved. In addition, the bending process can be performed before or after the joining process. The bending pattern can be formed by using concave and convex shapes as in the first embodiment, or by changing colors as in the second embodiment.

[0153] Thus, pattern 200 includes a bending pattern 203 indicating the bending position of the second molded body S5, and the second forming process includes a bending process of bending the second molded body S5 according to the bending pattern 203. As a result, bending processing can be performed quickly and accurately, a second molded body S5 with rich variations can be obtained quickly and accurately, and its productivity can be improved.

[0154] <Fourth Implementation>

[0155] Figure 9 This is a cross-sectional view of a third molded body manufactured by the molding body manufacturing apparatus according to the fourth embodiment of the present invention. Figure 10 This is a flowchart of a method for manufacturing a molded body according to the fourth embodiment of the present invention.

[0156] The following is for reference Figure 9 as well as Figure 10 The fourth embodiment of the method for manufacturing the molded article and the apparatus for manufacturing the molded article of the present invention will be described, but the following description will focus on the differences from the first embodiment, and the same items will be omitted.

[0157] like Figure 9 As shown, in this embodiment, a cutting pattern 204 is formed on the first molded body S3 as pattern 200. The cutting pattern 204 serves as a marker indicating the cutting position of the second molded body S5. The cutting pattern 204 is composed of recesses (grooves) formed at positions different from the recesses 201. In the illustrated structure, it is formed on both edges of the second molded body S5. Although not shown, the cutting pattern 204 is formed by... Figure 1 The pressure component 412 shown is formed by providing protrusions for forming cutting patterns 204 on the outer side of each protrusion 413 and performing a first forming process.

[0158] The cut pattern 204 and the recess 201 have different cross-sectional shapes. Therefore, the cut pattern 204 and the recess 201 can be easily visually distinguished. Thus, the joining process and the cutting process can be performed accurately respectively. Furthermore, the cut pattern 204 and the recess 201 are not limited to the above structure; they can also be the same shape.

[0159] In addition, such as Figure 10 As shown, in the manufacturing method of the molded body of this embodiment, as a second molding step, there is a cutting step that cuts the second molded body S5 along the cutting pattern 204. Therefore, the second molded body S5 can be cut and processed into a desired shape.

[0160] According to this structure, in the first forming process, in addition to the recess 201, the cutting pattern 204 can also be processed simultaneously. Therefore, the first molded body S3 can be manufactured with the same efficiency as in the first embodiment, and the cutting process can be performed quickly and accurately. As a result, a second molded body S5 with rich variations can be obtained quickly and accurately, and its productivity can be improved. In addition, the cutting process can be performed before or after the joining process. The cutting pattern can be formed with concave and convex shapes as in the first embodiment, or it can be formed with color changes as in the second embodiment.

[0161] Thus, pattern 200 includes a cutting pattern 204 indicating the cutting position of the second formed body S5, and the second forming process includes a cutting process that cuts the second formed body S5 at the cutting position. As a result, cutting processing can be performed quickly and accurately, a variety of second formed bodies S5 can be obtained quickly and accurately, and productivity can be improved.

[0162] While the manufacturing method and apparatus for the molded body of the present invention have been described above through the illustrated embodiments, the present invention is not limited thereto. Each part and process constituting the manufacturing method and apparatus for the molded body of the present invention can be replaced with any structure or process that can perform the same function. Furthermore, any structure or process may be added to the manufacturing method and apparatus for the molded body of the present invention. Moreover, the manufacturing method and apparatus for the molded body of the present invention can also combine features from each embodiment. The second molding process can be performed automatically by machinery, or at least part of it can be performed manually.

[0163] For example, the first and second embodiments can be combined, the first, second and third embodiments can be combined, the first, second, third and fourth embodiments can be combined, the first and third embodiments can be combined, the first and fourth embodiments can be combined, the second and third embodiments can be combined, the second, third and fourth embodiments can be combined, or the third and fourth embodiments can be combined.

[0164] Combining the first and second embodiments yields the following effects. For example, when the rod heater 414 of the second embodiment is disposed within the protrusion 413 of the first embodiment, a color-changing portion can be formed on the inner surface of the recess 201. This makes the pattern 200 easily identifiable both visually and tactilely. Furthermore, when the width of the rod heater 414 is narrower than the width of the recess 201, a portion of the bottom surface of the recess 201 can be selectively color-changed. In this case, even when the width of the third molding body S4 is narrower than the width of the recess 201, the color-changing portion can be easily concealed by the third molding body S4. Therefore, design flexibility can be further improved.

[0165] In addition, the pattern is not limited to the assembly pattern, bending pattern, and cutting pattern mentioned above, but can also be a pattern for other purposes.

[0166] Furthermore, "simultaneously" simply means within the same stroke. The transfer of the pattern and the bonding of the fibers can also not be completely synchronized in time. For example, the start times can be staggered, and the end times can also be staggered. Even if the recess is formed by applying pressure at the beginning, then colored by heating during subsequent pressure application, and finally solidified by cooling after heating, where the fibers bond together, it can still be called "simultaneous" as long as the operation is performed within the same stroke. It can be said that pressure is applied to transfer the pattern and the fibers bond together.
