Embodiments of the present invention will be described below with reference to the drawings.

Embodiment 1
FIG. 2 shows a brassiere as a female apparel manufactured by a molding apparatus according to Embodiment 1 of the present invention and a method for manufacturing a female apparel using the same.

In FIG. 2, reference numeral 1 denotes a brassiere as a female garment. The brassiere 1 includes left and right bust cup parts 2 and 3 as bulging parts respectively covering a female bust, and the left and right bust cup parts. Body bodies 4 and 5 are provided on the sides of 2 and 3. The left and right bust cup parts 2 and 3 and the body parts 4 and 5 are integrally formed. Further, shoulder cords 6 and 7 are provided on the shoulders of the human body from the vicinity of the tops of the left and right bust cup portions 2 and 3 to the body bodies 4 and 5 located on the back of the human body. Of course, the left and right bust cup parts 2 and 3 and the body parts 4 and 5 may be configured as separate bodies. Moreover, what is called a strapless type without a shoulder cord may be used.

Further, in the brassiere 1 according to this embodiment, a connecting tool (not shown) such as a hook or an eye is attached to the rear end portions of the left and right body parts 4 and 5 by means such as adhesion and sewing. These hooks and eyes are configured to be attached and detached via a connector (not shown).

By the way, the brassiere 1 is manufactured by hot press-molding a product to be molded, which has been formed into a product shape in advance by a two-dimensional pattern in consideration of the stretch ratio after molding, and is made into a semi-finished product. In the three-dimensionally formed women's apparel, the semi-finished product can be deformed following the shape of the mold when the hot press molding is performed, and has heat resistance. A necessary portion of the molded product is formed into a bulging shape by hot press molding using the mold die with the two sheet bodies interposed therebetween. It is configured as follows.

Here, the semi-finished product is a product that is configured in the same way as the product except for the molding process, or a semi-finished product that is already configured in the same way as the product except for the finishing process and the molding process. Including things.

Although the present invention mainly applies to semi-finished products to be molded, the application of the present invention is not limited to semi-finished products to be molded. It may be a molded product before being made into a semi-finished product in which it is difficult to secure a holding allowance around.

That is, the brassiere 1 basically includes a base fabric 10 that constitutes a brassiere as a female apparel such as a foundation. As shown in FIGS. 3 and 4, the base fabric 10 is configured by, for example, stretchable lace fabric, knitted fabric, or the like, and is formed on the front side and the back side of the base fabric 10 made of the lace fabric. As shown in FIG. 4, similarly, the outer material 11 and the lining material 12 as a base fabric are covered by adhesion or sewing through a resin layer 13 that functions as an adhesive layer. The base fabric 10 is composed of, for example, a lace fabric, but is not limited to this, and a technique material such as an embroidery lace, a torsion lace, a half tricot, or a mesh of a stretchable fabric, or these The technique material is not limited as long as it is suitable for the chest part configuration, such as a technique material that is folded in two and has an ear part. The outer material 11 is made of an elastic material having heat resistance and moldability, a satin fabric (preferably a knitted structure is acceptable, but a woven structure is also acceptable). Further, if the lining 12 is made of an elastic material having heat resistance and moldability, for example, a composite material of natural material such as non-moldable cotton (preferably a knitted structure is preferable, but a woven structure is also acceptable. ) Etc. are used.

Further, as shown in FIGS. 3 and 4, the brassiere 1 has a base fabric 10 made of lace, and a surface material 11 and a lining material 12 which are stretched by a cutting machine such as a press or a laser cutter. According to the two-dimensional pattern in consideration of the above, a product 14 is formed in advance, and is formed into a semi-finished product 14 by adhering or sewing these base fabric 10, outer material 11 and lining 12. It has become. Since the left and right bust cup portions 2 and 3 are stretched with respect to the two-dimensional pattern at the time of molding, the molded product 14 has a two-dimensional pattern shape in consideration of the expansion ratio of the left and right bust cup portions 2 and 3. Is set.

The material constituting the base fabric 10, or the outer material 11 and the lining material 12 need not have the same stretch rate over 360 degrees (all directions), but is an elastic material having directionality in the stretch rate such as one-way or two-way. There may be. In principle, the base fabric 10 or the like has no stretch ratio in the vertical and horizontal directions because fibers having elasticity such as spandex are not inserted in the width direction (knitting width direction). Therefore, when the bust cup portions 2 and 3 of the brassiere 1 are bulged and molded, the fabric may be distorted, and the two-dimensional pattern shape is designed in consideration of the distortion. In particular, the race place determines the design of the brassiere 1 and at the same time the configuration may be used from one to three configurations, so it is designed in a two-dimensional pattern shape taking distortion into consideration.

Next, as shown in FIG. 1, the swelled parts such as the left and right bust cup parts 2, 3, etc., are formed by hot press molding using a molding apparatus 100 ( A predetermined three-dimensional shape (three-dimensional shape) is formed by molding.

As shown in FIG. 1, the molding apparatus 100 includes a passive board 103 that is a basic part (working ground) arranged in a state of being fixed to the molding apparatus 100. The passive board 103 is formed in a planar rectangular frame shape by a heat insulating material which is a material having low thermal conductivity, for example. The passive plate 103 is provided with a convex first mold mold 101 located below and a concave second mold mold 102 located above so as to face each other vertically. Of course, the arrangement of the convex first mold mold 101 and the concave second mold mold 102 may be upside down. The first mold 101 is driven to move up and down by a first cylinder 104 that rises by a predetermined amount at a predetermined timing, and the second mold 102 is moved at a predetermined timing. It is driven to move up and down by the second cylinder 105 that descends by a predetermined amount. Further, the first mold die 101 and the second mold die 102 are heated to a predetermined temperature at the lower end portion of the first mold die 101 and the upper end portion of the second mold die 102. Heating plates 106 and 107 each incorporating a heater (not shown) are attached, and the first mold die 101 and the second mold die 102 are heated to a predetermined temperature (by the heating plates 106 and 107) during molding. For example, it is comprised so that it may heat to about 170-200 degreeC.

In the illustrated example, the first mold die 101 has a range that does not affect the first sheet body 109 as an example of the sheet body in order to facilitate the work of the operator on at least the passive board 103. It stops at a position below the first sheet body 109. The second mold 102 is also stopped above the passive board 103 and at an interval that does not affect the operation of setting the product to be molded on the first sheet body 109. As will be described later, a second sheet body 111 is set in the second mold mold 102, and at least the second mold mold 102 is attached to the passive plate 103 as the second sheet body 111. Since the molded product 14 set on the first sheet body 109 needs to be sandwiched and fixed together with the first sheet body 109 before contacting, the second mold mold 102 is required. It is located below by a distance of at least 1 cm or more. As will be described later, the distance varies depending on the pressure design of the urging means 114 including a seat body fixing guide cylinder or a spring. However, a short distance is desirable in order to effectively open the work space with the first sheet body 109. Here, the to-be-molded product 14 is the brassiere 1 manufactured by leaving the molding process as shown in FIGS. The body bodies 4 and 5 at the time of molding are preferably molded in the stretched state when the human body is worn. On the other hand, the bust cup parts 2 and 3 are designed to be compressed to a state in which the shape and the foundation function of the bust cup parts 2 and 3 can be exhibited when the body parts 4 and 5 are optimally fitted to the human body. Is desirable.

Further, the second sheet body 111 may be driven completely independently of the second mold mold 102, but the vertical movement is performed between the second sheet body 111 and the second mold mold 102. It is more efficient and desirable to perform the above in an integrated manner.

Further, as shown in FIG. 1, the passive board 103 is disposed in a state of being fixed at a predetermined position located between the first mold die 101 and the second mold die 102 as described above. ing. The passive board 103 is constituted by, for example, a frame made of a heat insulating material having a planar shape opened in a rectangular shape, and the passive board 103 has a rectangular shape through which the first mold die 101 passes. An opening 108 is provided.

Further, as shown in FIG. 1, a sheet fixing frame 110 for fixing the first sheet body 109 is attached to the outer periphery of the passive board 103 integrally or as a separate body. The first sheet body 109 located below is one of the two sheet bodies that are freely deformable following the shape of the first mold die 101 during hot press molding. It is stretched in a planar shape by means such as bonding or screwing via a frame.

As the first sheet body 109 and the second sheet body 111, for example, those formed in a thin sheet shape using a silicon resin or the like are used, but the present invention is not limited to this. Of course, other materials may be used as long as they are deformable following the shape of the first mold 101 and have heat resistance. Note that it is more preferable to use a sheet coated with a fluororesin or the like for the sheet body 109 made of silicon resin or the like in consideration of releasability from a molded product that has been made into a semi-finished product after hot press molding.

On the other hand, a sheet fixing frame 112 for fixing the second sheet body 111 is integrally attached to the outer periphery of the second mold die 102 as shown in FIG. The seat fixing guide member 113 is mounted so as to be able to appear and retract. The guide member 113 for fixing the seat is disposed on at least the left and right sides of the seat fixing frame 112, preferably on the four sides. The positive “hydraulic cylinder” and the “barometric cylinder” built in the seat fixing frame 112 or the depolarization are provided. A biasing means 114 such as a “spring method” is configured to project a predetermined distance below the second mold 102.

The sheet fixing frame 112 and the second sheet body 111 in which the urging means 114 integrated with the second mold die 102 are integrated, and at least the convex tip portion of the first mold die 101 is provided. The pulling force that is brought into contact with and pushed into the molded article 14 held between the second sheet body 111 and the first sheet body 109 held by the sheet fixing frame 112 must be opposed. Therefore, when the urging means 114 is of a spring type, it is necessary to hold the state in which the molded product 14 is sandwiched with the first sheet body 109 in opposition to the pulling force of the first mold 101. is there. Therefore, the biasing means 114 is set to a large spring constant so as to exert a pressure for completely sandwiching the molded product 14 when the second mold 102 comes into contact with the passive board 103 which is the base ground line. Yes.

On the outer periphery of the sheet fixing guide member 113, as shown in FIG. 1, it can be deformed following the shape of the second mold 102 during hot press molding and has heat resistance. The second sheet body 111 located above the sheet body is stretched in a planar manner by means such as adhesion or screwing via a frame body.

Further, on the first sheet body 109 stretched on the passive board 103, as shown in FIG. 1, the molded product 14 which is made into a semi-finished product is positioned at a predetermined position of the bust top of the brassiere 1. Thus, it is configured to be placed at a predetermined position. The molded product 14 may be a material other than a semi-finished product. The step of placing the semi-finished product 14 on the first sheet body 109 determines the shapes of the left and right bust cup portions 2 and 3 of the brassiere 1 as a product when hot press molding is performed. Therefore, it is necessary to position with respect to the mold dies 101 and 102 with high accuracy. Therefore, on the first sheet body 109, a positioning mark indicating a position on which the molded product 14 is placed is provided according to the size as necessary. The molded product 14 is placed on the first sheet body 109 according to the mark for use.

In addition, in this embodiment, at least one of the first and second sheet bodies 109 and 111, on the back surface of the first sheet body 109, as shown in FIG. An expansion control unit 120 that controls by suppressing or preventing the local expansion of the sheet body 109 is provided at a position corresponding to the unit. The expansion control unit 120 includes, for example, a plurality of sheet pieces 121a, 121b, and 121c that are made of the same material, such as silicon resin, as the sheet body 109 and are formed in different sizes such as a planar circular shape, an elliptical shape, or a rectangular shape. Are provided by means such as adhesion or welding in a state of being laminated concentrically. Further, the expansion control unit 120 has an expansion rate that is suppressed stepwise as compared with other regions of the first sheet body 109. More specifically, the expansion ratio of the first sheet body 109 is proportional to the thickness thereof, for example, as the thickness of the first sheet body 109 including the sheet pieces 121a, 121b, and 121c increases. Becomes lower.

In the above-described configuration, the brassiere as a female apparel according to this embodiment is manufactured as follows by manufacturing a female apparel such as the brassiere by molding. The presser allowance and punching allowance other than the shape are not required, and the loss of the base fabric can be eliminated. Combined parts (overlay, etc.) are integrated, and at the same time, the same dimension as in the bulging molding is achieved. And it can be refined (the difference between the convex outer area and the inner area can be formed without difficulty).

That is, in this embodiment, as shown in FIGS. 3 and 4, first, in order to form the brassiere 1 as a product, the base fabric 10, the outer fabric 11 and the lining 12 are cut into predetermined shapes, and these base fabrics are formed. 10 and the outer surface 11 and the lining 12 are bonded to each other through a resin layer 13 functioning as an adhesive, and a decorative fabric 15 made of lace or the like is also bonded to the inner edges of the left and right bust cup portions 2 and 3. By adhering via the resin layer 13 that functions as an agent, a molded product 14 that is a semi-finished product for forming the brassiere 1 is manufactured.

At this time, the brassiere 1 according to this embodiment does not need to provide the presser allowance at the time of molding in the outer fabric 11 and the lining 12, or the decorative fabric 15 made of a lace or the like as in the conventional product. In addition, useless dough that covers an area of 40 to 50% provided on the outer periphery of the brassiere 1 becomes unnecessary. That is, it is possible to perform a molding process as a final process in the state of the brassiere 1 that has been made into a semi-product.

As shown in FIG. 1, the molded product 14 that is semi-finished as described above is disposed between the first mold die 101 and the second mold die 102 of the hot press molding apparatus. Further, it is set at a predetermined position on the first sheet body 109 stretched around the passive board 103. Furthermore, in order to achieve further three-dimensional formation and functionalization, it can be enhanced by a two-step method or a diaphragm method.

Since the molded product 14 is placed at a predetermined position on the first sheet body 109 stretched on the passive board 103 as shown in FIGS. 1 and 6, the molded product 14 is The first sheet body 109 can be positioned at predetermined positions of the first mold die 101 and the second mold die 102 of the hot press molding apparatus 100 without providing an unnecessary pressing margin.

FIG. 1 shows a state of a hot press molding apparatus before operation for performing a molding process. FIG. 7 shows the state of the hot press molding apparatus during the molding process.

As described above, first, as shown in FIG. 1, on the first sheet body 109 stretched on the passive board 103, the molded product 14 is protruded particularly corresponding to the nipple (bust top portion). After positioning based on the apex of the mold, the second cylinder 105 located at the top is driven and lowered. At that time, the timing, speed, etc. for lowering the second cylinder 105 are matched to the operator's procedure, or a sensor (not shown) is attached to the sheet fixing guide 112 disposed on the outer periphery of the second mold 102. It is preferable to secure the attachment and the operator.

The sheet fixing guide 112 installed in the concave mold fixed to the pressure plate of the second mold die 102 first comes into contact with the sheet fixing guide 110 set on the outer periphery of the passive plate 103, and the product 14 is moved. The workpiece 14 is stopped at a predetermined pressure by the lowering of the second mold die 102 in a sandwiched manner, or the lower first cylinder 104 at a predetermined pressure step in the lowering step of the second mold die 102. Starts, presses against the second mold 102 while applying an appropriate amount of heat to the molded product 14 sandwiched between the two sheet bodies 109 and 111 on the passive board 103, and the second mold The mold 102 and the first mold mold 101 are stopped while being fitted to each other. At this time, the two sheet bodies 109 and 111 are in a state of being expanded to a shape corresponding to the shape of the first and second mold dies 101 and 102.

Thereafter, the cylinder 105 on the upper second mold die 102 side is actuated and moved up to a predetermined position on the upper side with an appropriate time (time required for applying the amount of heat necessary for the product set). . However, from the viewpoint of efficiency, the first mold die 101 or the second mold die 102 side, with the stage where the second mold die 102 is fitted and the product 14 is most set, A cooling device (not shown) placed in any one is activated to cool the molded product 14 in one machine, and the lower cylinder 104 or the upper cylinder 105 is activated at the most appropriate timing to set the mold 101 or 102 to a predetermined level. Preferably it is lowered or raised to a position.

In this way, the molding process is performed, and the appropriate time described above is to give a heat amount to fix the product shape, but the first and second mold dies 101 and 102 are released. At that time, the sheet bodies 109 and 111 try to immediately return to the flat state by the restoring force, so that the product that is the molded body 14 having the residual heat is the first mold mold 101 having a convex shape in particular. There is a possibility that the sheet body 109 may be damaged by the restoring action of the sheet body 109 at the moment of opening, for example, acting in a direction in which the bust cup portions 2 and 3 of the article to be molded 14 contract.

Therefore, in the above embodiment, it is desirable to add the cooling time of the molded product 14 to the “appropriate time” necessary for molding. However, it is preferable from the viewpoint of thermal efficiency that the molding dies 101 and 102 according to the present embodiment are kept substantially constant at a molding temperature of 170 to 200 ° C. From the viewpoint of thermal efficiency, Really inefficient.

Therefore, as means for solving this problem, the convex first mold mold 101 is used as a thermal mold for controlling molding, and the concave second mold mold 102 is used as a cooling means for different functions. It is preferable to set.

  As described above, in the above embodiment, as shown in FIGS. 1 and 7, the molded product 14 is positioned at a predetermined position by the first and second sheet bodies 109 and 111 during molding. Therefore, it is not necessary to provide a press margin for the product 14 itself, the press margin of the base fabric 10 and the like can be reduced as much as possible, and the base fabric 10 and the like are positioned and molded at a predetermined position. It becomes possible.

  At this time, the first sheet body 109 is provided with an expansion control unit 120 that prevents local expansion of the sheet body 109 at a position corresponding to the bust top portion of the bust cup portions 2 and 3. Therefore, when the first mold die 101 and the second mold die 102 are closed, the position corresponding to the bust top portion of the bust cup portions 2 and 3 is unnecessarily extended by the expansion control unit 120. There is no. Therefore, it is possible to prevent or suppress the occurrence of positional deviation in the molded product 14 during molding, and it is possible to perform mold molding with high accuracy. For further accuracy, it is preferable to mark the UB line and center line guidelines that determine the level of the product simultaneously with the nipple point.

  More specifically, the bust top portion of the brassiere 1 is the most protruding portion, and the region located around the bust top portion is a region having a gradient with respect to the bust top portion. For this reason, when the first mold die 101 and the second mold die 102 are closed, the position of the bust top portion may deviate from the original position due to uneven stretching force acting on the bust top portion from the surroundings. There is a risk that the amount of expansion varies.

  Therefore, by providing the expansion control unit 120 in the region corresponding to the bust top portion of the first sheet body 109, the region of the bust top portion of the first sheet body 109 becomes difficult to expand and is positioned at the bust top portion. It is possible to suppress or prevent the deviation and the variation in the extension amount from occurring.

  In addition, if necessary, at least one of an upper surface that is a surface in contact with the molded product 14 of the first sheet body 109 and a lower surface of the second sheet body 111, or preferably an upper surface of the first sheet body 109 and The surface roughness is set to be larger than that of other regions by applying pressure-sensitive adhesive to both the lower surfaces of the second sheet body 111, or by forming minute irregularities. By increasing the frictional force, the holding power of the molded product 14 is increased, and in principle, the product design is divided by the portion passing through the apex of the first mold 101 that also serves as a fulcrum at the time of swelling. Even if it exists, the position shift of the to-be-molded product 14 can be prevented, it can shape | mold to a predetermined three-dimensional shape, and the freedom degree of design property can be expanded infinitely.

Note that the first sheet body 109 and the second sheet body 111 constitute the first sheet body 109 and the second sheet body 111 without necessarily providing adhesiveness by applying an adhesive or the like. It may be configured to prevent the misalignment of the molded product 14 only by the viscosity of the silicon resin or the like.

As a result, the molded product 14 can be molded after the edge portion of the product, which is in the commercialization stage, is completely finished from the semi-finished state, and the production process can be compressed. Connected.

In addition, the first and second sheet bodies 109 and 111 have a heat resistance that can withstand the thermoforming temperature, and if the material does not negatively affect the product, a silicon resin film and a fluorine coating or a composite film thereof, You may use what consists of heat resistant rubbers.

Furthermore, it is preferable that the mold that assumes integral molding with the body body is designed to be molded after the product body before non-molding is stretched to the circumference of the human skeleton targeted by the product, The compression design may be made so as to obtain an appropriate shape in a situation where the mold is expanded to the circumference of the human body.

Especially in extreme bulges such as the breast, flare should occur around the breast, and the breast periphery should fit properly when worn, but conversely the body part around the breast rather than the breast May become weak. This is an important point especially when body parts such as body liners are integrated.

  In the above embodiment, the case where the first and second sheet bodies are provided as the sheet body has been described. However, the present invention is not limited to this, and as shown in FIG. The sheet body 109 may be provided only on the product holding passive device side provided on the 101 side.

  More specifically, as shown in FIG. 10, by making the cylinder for operating the second sheet body 111 independent, the volume of the second mold 102 can be increased and the cooling capacity can be increased. For example, the fixed guide 112 for the upper second sheet body 111 serves as a concave mold for thermoforming and is independent of the operation of the upper mold concave mold (cooling mold), thereby reducing the amount of heat of the product material and the mold mold. It is possible to adjust freely.

Note that depending on only the shape of the first and second mold dies 101 and 102, when the molded product 14 is molded, for example, the molded product has an outer surface shape of the first mold die 101 which is a convex mold. It is also assumed that it is difficult to press 14.
