DETAILED DESCRIPTION OF THE INVENTION
[0009] Hereinafter, embodiments of the present disclosure will be described. However, the present disclosure is not limited to the following embodiments. In the following embodiments, components (including element steps, etc.) are not essential unless otherwise specified. The same applies to numerical values and their ranges, and do not limit the present disclosure. In this specification, the term "layer" includes a configuration of a shape formed on a part of a surface as well as a configuration of a shape formed on the entire surface when observed in a plan view. Also, in this specification, a "layer" may be referred to as a "film." In this specification, the term "process" includes not only a process that is independent of other processes, but also a process that cannot be clearly distinguished from other processes as long as the purpose of the process is achieved. Note that, for convenience of explanation, in this embodiment, the directions indicated by arrows FR, UP, and LH shown appropriately in each figure are defined as the front side, upper side, and left side of the seamless product manufacturing apparatus 10, respectively.
[0010] (Overview) 1 is a schematic diagram showing one embodiment of seamless product manufacturing jigs 20, 22 and a seamless product manufacturing apparatus 10 (hereinafter simply referred to as "manufacturing apparatus 10") according to the present disclosure. As shown in this figure, the manufacturing jigs 20, 22 include a first jig 20 and a second jig 22. The manufacturing apparatus 10 also includes a table 12 on which the first jig 20 is placed, a nozzle 14 that dispenses adhesive, and a press mechanism 16 that is provided opposite the table 12.
[0011] The adhesive can be a hot melt adhesive whose main component is a thermoplastic polymer, and is preferably a reactive hot melt adhesive. Reactive hot melt adhesives form a three-dimensional crosslinked structure in response to moisture, light, etc., and are therefore suitable for improving heat resistance and adhesive strength. In this embodiment, as an example, the adhesive is a moisture-curing hot melt adhesive containing a urethane prepolymer.
[0012] As an example, the nozzle 14 is configured as the nozzle of an adhesive application device, such as a known dispenser, and is attached to the tip of an air-operated syringe. The syringe is filled with adhesive that has been melted by heating, and by applying a predetermined air pressure to the syringe, the adhesive is ejected from the tip of the nozzle 14 to a desired position. In this embodiment, the adhesive ejected from the nozzle 14 forms a dot-like pattern on the fabric 30 to form an adhesive layer 40 (see FIG. 40). The adhesive application pattern may also be a bead-like pattern. Thus, in this disclosure, the "adhesive layer formed on the fabric" includes both an adhesive layer formed by continuously applying adhesive to the fabric 30 and an adhesive layer formed by discontinuously applying adhesive to the fabric 30.
[0013] As an example, the press mechanism 16 includes a columnar rod 16A and a press plate 16B attached to the lower end of the rod 16A. The rod 16A is connected to an actuator such as a motor and is driven up and down by the driving force of the actuator. The press plate 16B clamps and presses the fabric 30 placed on the first jig 20 between the rod 16A and the table 12 by driving the rod 16A. This allows the adhesive surfaces of the fabrics on which the adhesive layer 40 has been formed to be pressed together.
[0014] The manufacturing apparatus 10 configured as described above produces seamless products made by bonding pieces of fabric together using an adhesive. Note that the term "seamless product" is a broad concept that includes products in which some of the fabric joints are joined seamlessly, and products in which all of the fabric joints are joined seamlessly.
[0015] In the manufacturing process according to the present disclosure, the edge of the fabric 30 is preferably bonded by using the first jig 20 and the second jig 22. In the following explanation, the configuration of the first jig 20 and the second jig 22 will be explained in detail, and the manufacturing process will be explained using seamless underwear (shorts) as an example.
[0016] (material) 2 is a plan view showing the state in which fabric 30 is placed on first jig 20. As shown in this figure, fabric 30 is composed of a single piece of flat-cut fabric in which a front body 32 and a back body 34 are connected via a crotch 36. One example of the fabric material used for fabric 30 is a stretchy fabric material into which synthetic fibers are knitted.
[0017] (First jig) The first jig 20 is a rectangular plate-like member that is placed on the table 12. In this embodiment, the first jig 20 is configured as a separate and independent component from the table 12; however, if the table 12 is movable horizontally by a driving force such as an actuator, the first jig 20 may be provided integrally with the table 12. The material that constitutes the first jig 20 is not particularly limited. For example, the first jig 20 can be formed from a metal material, a resin material, or a combination thereof. In this embodiment, the first jig 20 is formed from a metal plate, as an example.
[0018] Here, the first jig 20 has a first guide portion T1 that aligns the position of the fabric 30 relative to the first jig 20, and a second guide portion T2 that aligns the position of the second jig 22 relative to the first jig 20.
[0019] The first guide portion T1 provides a reference line that indicates the position of the edge of the fabric 30 when the fabric 30 is placed at a specified position on the first jig 20. The first guide portion T1 is configured to be visible when the fabric 30 is placed on the first jig 20. Therefore, in the manufacturing process, the edge of the fabric 30 is aligned along the first guide portion T1, thereby enabling alignment of the fabric 30 with respect to the first jig 20.
[0020] The first guide portion T1 configured as described above can be configured by paint on the upper surface, a groove formed in a concave shape on the upper surface, a protrusion provided in a convex shape on the upper surface, or the like. Also, by matching part of the shape of the end of the first jig 20 with part of the shape of the end of the fabric 30, the first guide portion T1 can be configured using the end of the first jig 20 as a reference line. In one example of this embodiment, the first guide portion T1 is configured by paint on the upper surface of the first jig 20, and indicates part of the outline that follows the end of the back body 34 of the fabric 30.
[0021] On the other hand, the second guide portion T2 provides a reference line that indicates the position of the end of the second jig 22 when the second jig 22 is placed at a specified position on the first jig 20. The second guide portion T2 is configured to be visible when the fabric 30 and the second jig 22 are placed on the first jig 20. Therefore, in the manufacturing process, the second jig 22 can be aligned with the first jig 20 by aligning the end of the second jig 22 along the second guide portion T2.
[0022] Like the first guide portion T1 described above, the second guide portion T2 can be configured by paint on the upper surface, a groove formed in a concave shape on the upper surface, a protrusion provided in a convex shape on the upper surface, or the like. Furthermore, by matching a portion of the shape of the end of the first jig 20 with a portion of the shape of the end of the second jig 22, the second guide portion T2 can be configured using the shape of the end of the first jig 20 as a reference line. In one example of this embodiment, the second guide portion T2 is configured by the front end portion 20F of the first jig 20. The second jig 22 can be aligned with the first jig 20 by arranging the position of the front end portion 22F of the second jig 22 along the second guide portion T2.
[0023] (Second jig) The second jig 22 is a plate-like member formed in a rectangular shape. The second jig 22 is placed on top of the first jig 20 with the substrate 30 interposed between them. The material constituting the second jig 22 is not particularly limited. For example, the second jig 22 can be made of a metal material, a resin material, or a combination thereof. As an example, the second jig 22 in the embodiment is made of a metal plate.
[0024] The second jig 22 is placed on top of the first jig 20, thereby sandwiching and pressing the back body 34 of the fabric 30 between the first jig 20 and the second jig 22. In this state, a portion of the outer peripheral edge of the second jig 22 forms a guide edge T3 that guides the folding position of the fabric 30. In this embodiment, the left and right end portions 22R, 22L and the rear end portion 22B of the second jig 22 form the guide edge T3. The rear end portion 22B of the second jig 22 corresponds to the "first guide edge" in this disclosure, and the left and right end portions 22R, 22L of the second jig 22 correspond to the "second guide edge" in this disclosure.
[0025] 3 shows a plan view of the second jig 22 placed on top of the first jig 20, which has the fabric 30 placed on its upper surface. In this figure, the outline of the fabric 30 shown by the two-dot chain line indicates the unfolded state of the fabric 30. The outline of the fabric 30 shown by the solid line indicates the outline of the fabric 30 when it is folded back along the guide end T3.
[0026] As shown in this figure, when the second jig 22 is placed on top of the first jig 20, the ends of the back body 34 of the fabric 30 are configured to protrude from the left and right end portions 22R, 22L of the second jig 22. Furthermore, the front body 32 of the fabric 30 is configured to protrude from the rear end portion 22B of the second jig 22. These end portions of the fabric 30 protruding from the second jig 22 are folded back along the guide end portion T3, so that the end portions of the front body 32 and the back body 34 overlap on the top surface of the second jig 22. That is, in this embodiment, a fold line is formed on the fabric 30 at the position of the guide end portion T3, so that the fabric 30 is folded back along the guide end portion T3.
[0027] (Method for manufacturing seamless products using manufacturing jigs) 4(A) to 4(F), a method for manufacturing a seamless product using the above-described first jig 20 and second jig 22 will be described. In the manufacturing method of this embodiment, an adhesive layer 40 is formed on the fabric 30 while the fabric 30 is held down between the first jig 20 and the second jig 22, and the edge of the fabric is folded back along the guide edge T3 of the second jig 22, so that the folded edge of the fabric 30 is superimposed on the adhesive layer 40.
[0028] In the fabric pressing process, first, the fabric 30 is placed on the first jig 20 (FIG. 4(A)). At this time, the edge of the fabric 30 is positioned along the first guide portion T1 of the first jig 20, thereby aligning the fabric 30 with the first jig 20. Thereafter, the second jig 22 is positioned along the second guide portion T2 of the first jig 20, and the second jig 22 is placed on top of the first jig 20 (FIG. 4(B)). As a result, the back body portion 34 of the fabric 30 is sandwiched and pressed between the first jig 20 and the second jig 22, which prevents the fabric from shifting position during the subsequent folding process.
[0029] The folding process includes a first folding process performed before the adhesive application process and a second folding process performed after the adhesive application process. The folding process may be performed manually or by air blowing.
[0030] In the first folding step, the front body 32 of the fabric 30 protruding from the rear end 22B (guide end T3) of the second jig 22 is folded back along the end 22B (FIG. 4(C)).
[0031] After the first folding step, the adhesive layer forming step is performed. In the adhesive layer forming step, the first jig 20 is moved to the front of the table 12 and set to match the position of the nozzle 14, which is set in a fixed position. Thereafter, when the nozzle 14 starts to discharge adhesive, the first jig 20 is slid back and forth so that the tip of the nozzle 14 moves along the left and right edges of the front body 32 (FIG. 4(D)). This forms an adhesive layer 40 on the left and right edges of the front body 32. The movement of the first jig 20 at this time may be performed manually, or may be performed automatically by connecting the first jig 20 to a drive actuator.
[0032] This adhesive layer forming step may be any step in which the adhesive layer 40 is formed on at least one of the fabrics of the front body 32 and the back body 34 at the overlapping portion between them. Therefore, the adhesive layer 40 may be formed not on the front body 32 but on the end portions of the back body 34 that protrude from the end portions 22R, 22L (guide end portions) on both the left and right sides of the second jig 22. Alternatively, the adhesive layer 40 may be formed on both the front body 32 and the back body 34.
[0033] After the adhesive application step, in the second folding step, the ends of the back body 34 protruding from the left and right end portions 22R, 22L (guide end portions T3) of the second jig 22 are folded back along the left and right end portions 22R, 22L of the second jig 22 (FIG. 4(E)). As a result, on the upper surface of the second jig 22, the end portion of the back body 34 is overlapped with the end portion of the front body 32 on which the adhesive layer 40 has been formed.
[0034] After the second folding step, a pressurizing step is carried out to press the adhesive surfaces of the fabric pieces together (FIG. 4(F)). In this pressurizing step, the first jig 20 is moved below the press mechanism 16, and the press plate 16B is pressed against the upper surface of the second jig 22 to temporarily press the adhesive surfaces of the fabric pieces together. This completes the three-dimensional shape of the shorts.
[0035] Thereafter, the fabric 30 is removed from the second jig 22, and the adhesive surfaces are thermocompressed using a heat press (not shown), completing the manufacturing process of the seamless garment. Note that the pre-compression step may be omitted by configuring the press mechanism 16 of the seamless product manufacturing apparatus 10 as a heat press mechanism.
[0036] (Action and effect) As described above, in this embodiment, after the fabric 30 is placed on the first jig 20, the second jig 22 is placed on top of the first jig 20, so that the fabric 30 can be sandwiched and pressed between the first jig 20 and the second jig 22. This makes it possible to prevent the fabric 30 from slipping on the first jig 20 and becoming misaligned when folding back the end of the fabric 30 along the guide end T3 (22B, 22R, 22L) of the second jig 22. This makes it possible to improve the accuracy of the folding position of the fabric 30.
[0037] Furthermore, since the folding position of the fabric 30 is guided along the guide end T3 of the second jig 22, the accuracy of the folding position can be improved while improving workability. In this way, it is possible to reduce defects in the bonding position of the edge of the fabric 30 and improve productivity.
[0038] The first jig 20 is provided with a first guide section T1 that aligns the fabric 30 with respect to the first jig 20, and a second guide section T2 (20F) that aligns the second jig 22 with respect to the first jig 20. This makes it possible to place the fabric 30 on the first jig 20 along the first guide section T1, and then place the second jig 22 on top of the first jig 20 along the second guide section T2. This makes it easy to align the fabric 30 and the second jig 22 with respect to the first jig 20, further improving workability.
[0039] By folding back the edge of fabric 30 along guide edge T3 of second jig 22, it is possible to precisely align the overlapping positions of the edge of front body 32 and the edge of back body 34 of fabric 30. This reduces defects in the bonding position of the edge of fabric 30 and improves productivity in the production of seamless garments that have front and back bodies.
[0040] (First Modification of Manufacturing Jig) 5 to 7, a description will be given of manufacturing jigs 50 and 52 according to a first modified example and a method for manufacturing a seamless product using the manufacturing jigs 50 and 52. Note that the same components as those in the above embodiment are given the same reference numerals and their description will be omitted.
[0041] 5, the manufacturing jigs 50, 52 according to the first modification include a first jig 50 and a second jig 52. The first jig 50 and the second jig 52 can be used when folding back and gluing the edge of a neck portion 62 of fabric 60, such as a T-shirt, formed as a seamless garment.
[0042] The first jig 50 has basically the same configuration as the first jig 20 of the above embodiment and is made of a rectangular metal plate. A first guide portion T1 is formed on the top surface of the first jig 50 to align the edge of the fabric 60. In this first modification, the first guide portion T1 provides an arc-shaped reference line for aligning the edge of the neck portion 62 of the T-shirt. The first guide portion T1 is made of an arc-shaped paint mark on the top surface of the first jig 50. Furthermore, the rear end portion 50B of the first jig 50 constitutes a second guide portion T2 that aligns the rear end portion 52B of the second jig 52, which will be described later.
[0043] The second jig 52 is made of a rectangular metal plate. As in the above embodiment, this second jig 52 is placed on top of the first jig 50 with the fabric 60 interposed between the first jig 50 and the second jig 50. The front end 52F of the second jig 52 is formed in an arc shape cut out to correspond to the shape of the neck portion 62 of the fabric 60. This forms a guide end T3 that guides the folding position of the end of the neck portion 62 during the folding process during manufacturing. As shown in FIG. 6 , when the second jig 52 is placed on top of the first jig 50, the end of the neck portion 62 of the fabric 60 protrudes from the front end 52F of the second jig 52. After the adhesive layer 40 is formed on the upper surface, the end of the neck portion 62 is folded back along the front end 52F (guide end T3) of the second jig 52. At this time, the neck portion 62 is folded back so that the folded end of the fabric is aligned with the front end 52F of the second jig 52. As a result, the edge of the fabric of the neck portion 62 is folded back at a specified width and adhered. That is, in the configuration according to the first modification, the guide end T3 is used as a reference line for aligning the folded back portion of the fabric, and the fold line of the fabric 60 is formed at a position different from the guide end T3.
[0044] In a method for manufacturing a seamless product using the manufacturing jigs 50, 52 configured as described above, in a fabric pressing step, the fabric 60 is placed on the first jig 50 along the first guide portion T1, and then the second jig 52 is placed on top of the first jig 50 along the second guide portion T2 (FIGS. 7(A)-7(B)). Then, in an adhesive layer forming step, adhesive is applied from a nozzle 14 to the neck portion 62 of the fabric 60 protruding from the second jig 52 to form an adhesive layer 40 (FIG. 7(C)). In a folding step following the adhesive layer forming step, the neck portion 62 of the fabric 60 is folded back along the front end 52F (guide end portion T3) of the second jig 52 and overlapped with the adhesive layer 40 (FIG. 7(D)). Then, in a pressure applying step, a pressing jig 54 is placed above the fabric 60 to press down the folded portion of the neck portion 62. Then, after removing the second jig 52 from under the pressing jig 54, the adhesive surfaces of the fabrics are pressed together by the press mechanism 16 to temporarily bond them together (FIGS. 7(E) to 7(F)). Finally, the pressing jig 54 is removed from the top surface of the fabric 60, and the adhesive surfaces of the fabrics are thermally pressed together by a heat press. The temporary bonding step may be omitted by configuring the press mechanism 16 as a heat press mechanism.
[0045] As described above, in the first modified example, similarly to the above embodiment, the fabric 60 can be sandwiched and pressed between the first jig 50 and the second jig 52. Furthermore, the folded position of the end of the fabric 60 is guided along the guide end T3 of the second jig 52. Therefore, it is possible to reduce defects in the bonding position of the end of the fabric 60 and improve productivity.
[0046] (Second Modification of Manufacturing Jig) 8 to 10, a description will be given below of manufacturing jigs 70 and 72 according to a second modified example and a method for manufacturing a seamless product using the manufacturing jigs 70 and 72. Note that the same components as those in the above embodiment are given the same numbers and their description will be omitted.
[0047] 8, manufacturing jigs 70, 72 according to the second modification are composed of a first jig 70 formed of a rotating roller and a ring-shaped second jig 72 placed on top (on the outer periphery) of the first jig 70. These first and second jigs 70 and 72 can be used when folding back and gluing the end of a tubular hem 82 of fabric 80 such as a T-shirt formed as a seamless garment.
[0048] The first jig 70 has a rotary shaft 74 connected to an actuator (not shown) and rotates around the rotary shaft 74. The first jig 70 also has a first guide portion T1 that provides a reference line for aligning the end of the hem portion 82 when the fabric 80 is placed on the first jig 70. The first guide portion T1 according to this second modified example is, as an example, configured with dots of paint that extend circumferentially around the outer circumferential surface of the first jig 70. Furthermore, one axial end 70F of the first jig 70 is configured as a second guide portion T2 that aligns with the second jig 72, which will be described later.
[0049] As shown in FIG. 9 , the ring-shaped second jig 72 is attached to the outer circumferential surface of the first jig 70 after the cylindrical hem portion 82 is placed over the outer circumferential surface of the first jig 70. This positions the second jig 72 on top of (the outer circumferential surface of) the first jig 70. At this time, the end 72F on one axial side of the second jig 72 is placed so as to overlap the position of the second guide portion T2 of the first jig 70, thereby aligning the second jig 72 with the first jig 70. Meanwhile, the hem portion 82 of the fabric 80 protrudes from the end 72B on the other axial side of the second jig 72. While the first jig 70 is rotating around the rotation axis 74, adhesive is applied to the hem portion 82 from the nozzle 14 to form the adhesive layer 40. The hem portion 82 of the fabric 80 is then folded back along the end 72B (guide end T3) on the other axial side of the second jig 72 and overlapped on the adhesive layer 40. As a result, the edge of the fabric of the hem 82 is folded back at a specified width and adhered.
[0050] In a method for manufacturing a seamless product using the manufacturing jigs 70, 72 configured as described above, in a fabric pressing step, a cylindrically formed fabric 80 (hem portion 82) is placed on one axial side of the first jig 70 along the first guide portion T1, and then a ring-shaped second jig 72 is attached to the outer peripheral surface of the first jig 70 (FIGS. 10(A)-10(B)). Then, in an adhesive layer forming step, the first jig 70 is rotated to form an adhesive layer 40 around the entire periphery of the hem portion 82 (FIG. 10(C)). In a folding step following the adhesive layer forming step, the end of the hem portion 82 is folded back along the other axial end 72B (guide end portion T3) of the second jig 72 and overlapped with the adhesive layer 40 (FIG. 10(D)). Then, in a pressure applying step, while the first jig 70 is rotated, a pressure roller 76 is pressed against the folded back portion of the hem portion 82, thereby temporarily pressing the adhesive surfaces of the fabrics together. Finally, the fabric 80 is removed from the first jig 70, and the adhesive surfaces of the fabrics are thermocompressed together using a heating laminator. The temporary pressure-bonding step may be omitted by configuring the pressure-bonding roller with a heating mechanism.
[0051] As explained above, in the second modified example, similarly to the above embodiment, the fabric 80 can be sandwiched and pressed between the first jig 70 and the second jig 72. Furthermore, the folded position of the end of the fabric 80 is guided along the guide end T3 (72B) of the second jig 72. Therefore, it is possible to reduce defects in the bonding position of the end of the fabric 80 and improve productivity. [Explanation of symbols]
