Operation and effect of the invention
According to the present invention, the elastic belt member is divided into two in the width direction together with the leg elastic member, and the divided first elastic belt material and the second elastic belt material are separated in the width direction. By shifting the phase in the length direction so that the members are paired and attaching the absorber across the first elastic belt material and the second elastic belt material, the leg elastic member is cut in the manufacturing process. Since no loss portion is generated, the manufacturing cost of the worn article can be reduced.
[0017]
Further, by dividing the elastic belt material manufactured by sandwiching the leg elastic member with the same tension between the two webs, when the manufactured disposable wearing article is worn, the front portion and the back portion Since the tension (shrinkage force) of the leg elastic members is not different, wrinkles are less likely to occur at the front portion and the back portion, so that the appearance is improved and the commercial value of the worn article can be improved.
[0018]
According to the second aspect of the present invention, the absorber side leg elastic members attached to both sides of the absorber are continuously connected to the leg elastic members of the front portion and the back portion, so that contraction force is generated around the entire leg hole. It becomes like this.
[0019]
According to the third aspect, before or after the elastic belt member is divided into two in the width direction, a leg hole can be formed in the first elastic belt member and the second elastic belt member along the leg elastic member.

In Claim 4, after attaching an absorber straddling the 1st elastic belt material and the 2nd elastic belt material, the elastic member for legs is attached to the 1st elastic belt material, the 2nd elastic belt material, and the absorber. Leg holes can be drilled along. In this case, the leg hole is a clean leg hole in which the first elastic belt material, the second elastic belt material, and the absorbent body have no protruding portion or the like.
[0021]
According to the fifth aspect of the present invention, the absorbent body is mounted across the portion where the contraction force in the vicinity of the convex portions of the first elastic belt member and the second elastic belt member is reduced, so that the contraction force does not act on the absorber. Thereby, since an absorber does not contract by contractive force, the adhesiveness with respect to a body can be improved.
[0022]
In Claim 6, a wear article can be made into a pants type.
[0023]
According to the seventh aspect, the side flaps from both sides of the absorber can be effectively prevented by the rising flap.
[0024]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0025]
14A is a perspective view of a pants-type disposable wearing article (hereinafter referred to as “disposable pants”) 1 in use, FIG. 14B is a front view, and FIG. 15 is a plan view of a developed state.
[0026]
The disposable pants 1 have an absorbent body 2 attached over a front part (first elastic belt material) P and a back part (second elastic belt material) Q, and the front part P and the back part Q are connected to the absorbent body. 2 is folded and overlapped, and both sides 1a of the front part P and the back part Q are side-sealed to form a pants type.
[0027]
In the disposable pants 1, a crotch (crotch) portion R is formed by the absorbent body 2, and leg holes S are formed on both sides of the absorbent body 2.
[0028]
The manufacturing method of the said disposable pants 1 is demonstrated concretely using FIGS.
[0029]
(1) Steps 1 to 4 are steps of manufacturing the first elastic belt material 12A and the second elastic belt material 12B from the elastic belt material 12 in a lateral flow state.
[0030]
[Step 1] In FIG. 1, FIG. 2, and FIG. 9, a front portion P side and a back portion are arranged between a nonwoven fabric outer web 10 and a nonwoven fabric inner web 11 continuously fed in the length direction A. At the same time the body-fit elastic member 4 on the Q side is sandwiched in the lengthwise direction A, and the width W2 of the disposable pants 1 is set as one cycle, the body-fit elastic member 4 on the front part P side and the back part Q side The elastic member 12 is produced by sandwiching the leg elastic members 5 in the lengthwise direction A so as to meander between them (see FIGS. 9A to 9C).
[0031]
For example, a hot melt adhesive is applied to at least one of the webs 10 and 11, and the webs 10 and 11 are bonded together with the body fit elastic member 4 and the leg elastic member 5 sandwiched therebetween.
[0032]
As the material for the body fit elastic member 4 and the leg elastic member 5, polyurethane, natural rubber, thermoplastic resin, etc. can be used, and the shape can be thread, ribbon, etc. It may be used. When a thermoplastic resin is used as a material, a hot melt adhesive may be unnecessary if the web 10 or 11 has a function of adhering to the web itself. In addition, each elastic member 3, 6, and 7 mentioned later is also the same material and shape.
[0033]
[Step 2] The elastic belt material 12 is cut in two in the width direction W into the first elastic belt material 12A and the second elastic belt material 12B in step 3 described below. The part 12c in which the contraction force is reduced is formed by reducing the contraction force of the body fitting elastic member 4 at the portion where the absorber 2 is attached in the first elastic belt member 12A and the second elastic belt member 12B. Is preferred.
[0034]
As a process for reducing the shrinkage force, for example, a method of melting the body fitting elastic member 4 using an embossing roll (heat embossing) (see Japanese Patent Application Laid-Open No. 2002-113042) or a body cutter elasticity using a gather cutter 14 is used. A method of cutting the member 4 can be employed. This melting or cutting is preferably performed in a state where the elastic belt member 12 is stretched along the roll while being vacuumed.
[0035]
In addition, as long as the process of making shrinkage force small is a process until the process 10 which attaches the absorber 2 mentioned later, any may be sufficient.
[0036]
[Step 3] A center line (cutting line) L in the width direction W of the elastic belt member 12 and a region 15 f and g partitioned by the leg elastic member 5, along the leg elastic member 5, the cutter 15. The leg hole S is opened and the elastic belt member 12 is cut in two in the width direction W to produce the first elastic belt member 12A and the second elastic belt member 12B.
[0037]
That is, as shown in detail in FIG. 7A, a leg hole S is drilled along the leg elastic member 5 in a mountain shape as shown by cross hatching, and the connected portion x before and after the leg is cut. Then, the elastic belt member 12 is cut in two in the width direction W together with the leg elastic member 5. In step 14 to be described later, the first elastic belt member 12A is cut by a cut line y to form a front portion P as shown by hatching, and the second elastic belt member 12B is cut by a cut line y. Thus, a back portion Q as shown by hatching is formed.
[0038]
[Step 4] The first elastic belt member 12A and the second elastic belt member 12B divided into two parts are separated at a constant interval W1 in the width direction W, and the leg hole S and the leg elastic member 5 have the same phase. In this way, the half phase is shifted in the length direction A (see FIG. 9D). Note that the step of separating the first elastic belt member 12A and the second elastic belt member 12B may be performed from the time when the absorbent body 2 is bonded after being cut into two parts.
[0039]
As a method of shifting the phase, for example, the distance that the first elastic belt member 12A is continuously fed in the length direction A is made longer than the distance that the second elastic belt member 12B is continuously fed in the length direction A. Can be done. Specifically, by sending the first elastic belt member 12A along the dummy roll 16, the distance to be sent can be increased.
[0040]
(2) Steps 5 to 9 are steps for manufacturing the absorbent body 2 in a longitudinal flow state.
[0041]
[Step 5] In FIG. 1, FIG. 3 and FIG. 10, between the wide backsheet 20a made of nonwoven fabric continuously fed in the length direction A and the liquid-impermeable narrow backsheet 20b, the absorber side The leg elastic member 6 is sandwiched in the lengthwise direction A in a stretched state and bonded with a hot melt adhesive or the like.
[0042]
When the absorber 2 leg elastic member 6 is attached across the first elastic belt material (front portion P) 12A and the second elastic belt material (back portion Q) 12B in the step 10 described later, The leg elastic member 5 is sandwiched so as to form a continuous arc (see FIG. 15).
[0043]
Further, both ends of the wide back sheet 20a in the width direction are bonded to the inner bent portion 20c which is bent inward by the sailor 28, and the elastic member for flap 7 is stretched along the length direction A in a stretched state [FIG. see a)]. As the liquid-impermeable sheet, polyethylene and a nonwoven fabric having water repellency and air permeability are preferable. The back sheet 20a may be a liquid-impermeable sheet, the back sheet 20b may be a liquid-permeable sheet, and the back sheets 20a and 20b may be liquid-impermeable sheets. That is, it is only necessary that the backsheet can prevent liquid leakage from the core 2a of the absorbent body 2.
[0044]
[Step 6] The core 2a of the absorbent body 2 is formed in a cross-flow state by a method of laminating fluffs obtained by pulverizing roll pulp 17 with a pulverizer 18 onto a pattern drum 19 (see Japanese Patent Laid-Open No. 63-139547). To do. The fluff may be mixed with a superabsorbent polymer.
[0045]
When the core 2a is manufactured in a transverse flow state, the orientation of the core 2a is reversed by 90 degrees by a re-pitch / turn drum to obtain a longitudinal flow state (see International Publication No. WO01 / 44086).
[0046]
[Step 7] The back sheets 20a and 20b manufactured in Step 5 are turned upside down and turned upside down, and the core 2a is placed on the back sheet 20b on the upper side in a vertical flow state [FIG. b)], by adhering the liquid-permeable top sheet 20d to the back sheet 20b together with the core 2a with a hot-melt adhesive or the like (see FIG. 10C), the absorbent body 2 is long in the longitudinal direction A. Manufacturing. As the liquid permeable sheet, a liquid permeable nonwoven fabric or a mesh sheet is preferable.
[0047]
[Step 8] The rising flaps 8 are formed by folding the inner bent portions 20c at both ends of the back sheet 20a on the lower side inward [see FIG. 10 (d)]. Further, instead of forming the rising flap 8 by the back sheet 20a or 20b, the rising flap may be formed by the top sheet 20d. In that case, it is preferable that a waterproof treatment is applied to a portion of the top sheet 20d which becomes a rising flap.
[0048]
[Step 9] The absorbent body 2 that is long in the length direction A is cut by the built-in cutter 21 along the rising flap 8 with a certain length to produce the rectangular absorbent body 2.
[0049]
When the absorbent body 2 is attached to the absorbent body 2 across the first elastic belt material (front portion P) 12A and the second elastic belt material (back portion Q) 12B in Step 10 to be described later, the above-mentioned leg It is preferable to form a cut 2c along the absorber-side leg elastic member 6 so as to form an arc shape continuous with the hole S (see FIG. 15).
[0050]
(3) Steps 10 to 15 are steps for assembling the disposable pants 1 in a lateral flow state.
[0051]
[Step 10] In FIG. 1, FIG. 4 and FIG. 11, the absorbent body 2 manufactured in Step 9 is reversed 90 degrees with the internal turn drum 23 to be in a lateral flow state (see the left end diagram of FIG. 3). .
[0052]
On the other hand, the first elastic belt material 12A and the second elastic belt material 12B manufactured in the step 4 are turned upside down and turned upside down, and the absorbent body 2 is made up of the first elastic belt material 12A and the second elastic belt. Bonding is performed across the portion 12c where the contraction force of the material 12B is reduced [see FIG. 11 (a)].
[0053]
[Step 11] The elastic member 3 for waist is stretched in the length direction A along the both ends 12d in the width direction W on the outer web 10 side of the first elastic belt material 12A and the second elastic belt material 12B. The both end portions 12d are folded inward, and the elastic member 3 for the waist is bonded into the both end portions 12d [see FIG. 11 (b)]. Both end portions 12d are also bonded to the front and rear end portions of the absorbent body 2 so as to cover the front and rear end portions of the absorbent body 2.
[0054]
[Step 12] The absorbent body 2 is folded at the middle position in the width direction W by the folding device 24 so that the first elastic belt member 12A is on the upper side and the second elastic belt member 12B is on the lower side. Superimpose them (see FIG. 11C).
[0055]
[Step 13] An intermediate position (corresponding to both side portions 1a of the disposable pants 1) between adjacent absorbent bodies 2 of the folded first elastic belt material 12A and second elastic belt material 12B is a plurality of stages of heat seals 25a. Fusing at ~ 25c, side seal. In addition, the heat seals 25a to 25c are not necessarily required to have a plurality of stages. Further, side sealing may be performed by sonic instead of the heat seals 25a to 25c.
[0056]
[Step 14] When the intermediate portion of the side-sealed portion 1b of the first elastic belt material 12A and the second elastic belt material 12B is cut with the product cutter 26, the disposable pants 1 in which both side portions 1a are side-sealed are completed.
[0057]
[Step 15] The disposable pants 1 as the product is turned 90 degrees by the product turning machine 27 and then sent from the product inspection process to the packaging process.
[0058]
Of the above steps 1 to 15, in step 3, the elastic belt member 12 is divided into two in the width direction together with the leg elastic member 5, and the divided first elastic belt member 12A and second elastic belt member 12B are divided into widths. In the state separated in the direction W, the phase is shifted in the length direction A so that the leg elastic members 5 are paired, and the absorber 2 is separated into the first elastic belt material 12A and the second elastic belt material 12B. Since the loss portion does not occur even when the leg elastic member 5 is cut in the manufacturing process, the manufacturing cost of the disposable pants 1 can be reduced.
[0059]
Further, when the manufactured disposable pants 1 are worn by splitting the elastic belt material 12 manufactured by sandwiching the elastic member 5 for the leg with the same tension between the two webs 10 and 11, the front Since the tension (shrinkage force) of the leg elastic members 5 of the part P and the back part Q is not different, the front part P and the back part Q are less likely to be wrinkled. Product value can be improved.
[0060]
Further, the absorber side leg elastic members 6 attached to both sides of the absorber 2 are continuously connected to the leg elastic members 5 of the front part P and the back part Q, so that the entire area around the leg hole S contracts. Force will be generated.
[0061]
Further, in step 3, before the elastic belt member 12 is divided into two in the width direction W, the leg hole S is formed along the leg elastic member 5 in the first elastic belt member 12A and the second elastic belt member 12B. Can dawn. In addition, after the elastic belt member 12 is divided into two in the width direction W, the leg hole S can be formed along the leg elastic member 5.
[0062]
Furthermore, by attaching the absorber 2 across the portion 12c where the contraction force of the first elastic belt member 12A and the second elastic belt member 12B is reduced, the contraction force does not act on the absorber 2. Thereby, since the absorber 2 is not contracted by the contraction force, the adhesion to the body can be improved.
[0063]
Moreover, the side flap from the both sides of the absorber 2 can be effectively prevented by the rising flap 8 of the absorber 2.
[0064]
In the above-described embodiment, the leg hole S was opened in Step 3, but after the absorbent body 2 was bonded across the first elastic belt material 12A and the second elastic belt material 12B in Step 10, Leg holes S can be formed in the first elastic belt member 12A, the second elastic belt member 12B, and the absorber 2 along the leg elastic member 5 and the absorber-side leg elastic member 6.
[0065]
As shown in FIG. 5, the elastic belt member 12 is cut into two in the width direction W by the cutter 15 at the center line L without opening the leg hole S in Step 3, and the first elastic belt member 12A and the second elastic belt member 12 The elastic belt material 12B is manufactured.
[0066]
That is, as shown in detail in FIG. 7B, the elastic belt member 12 is cut into two in the width direction W along the leg elastic member 5 along the center line L. In step 14 to be described later, the first elastic belt member 12A is cut by a cut line y to form a front portion P as shown by hatching, and the second elastic belt member 12B is cut by a cut line y. Thus, a back portion Q as shown by hatching is formed.
[0067]
In step 4, the first elastic belt member 12A and the second elastic belt member 12B divided into two parts are separated at a constant interval W1 in the width direction W, and the leg elastic members 5 are in phase. The half phase is shifted in the length direction A.
[0068]
Thereafter, as shown in FIG. 6, in step 10, the absorbent body 2 is bonded across the portion 12 c where the contraction force between the first elastic belt member 12 </ b> A and the second elastic belt member 12 </ b> B is reduced. In addition, it is not necessary to form the notch | incision 2c which becomes circular arc shape in the said process 9 in the absorber 2. FIG.
[0069]
Then, in Step 10 ′ between Step 10 and Step 11 (see FIG. 1), the first elastic belt material 12A and the second elastic belt material 12B are absorbed by the elliptical die cutter 30 for the leg hole S. An elliptical leg hole S is simultaneously formed in the body 2 along the leg elastic member 5 and the absorber-side leg elastic member 6 (see cross-hatching in FIGS. 6 and 7C).
[0070]
In this case, the leg hole S is a clean leg hole S in which the first elastic belt member 12A, the second elastic belt member 12B, and the absorber 2 have no protruding portion or the like.
[0071]
In the above embodiment, the absorber side leg elastic member 6 is sandwiched and bonded between the back sheets 20a and 20b as shown in FIG. 12 (a), but as shown in FIG. 12 (b), the back sheet 20b and The absorber-side leg elastic member 6 may be sandwiched between the top sheet 20d and bonded, or as shown in FIG. 12C, the back sheet 20a is not provided, and the top sheet 20d is backed together with the core 2a. While adhering to the sheet 20b with a hot melt adhesive or the like, the absorber-side leg elastic member 6 may be sandwiched between the lower end portion of the separate rising flap 8 and the top sheet 20d.
[0072]
In the above embodiment, as shown in FIG. 13A, the leg elastic members 6 for the absorber are bonded to both sides of the absorber 2 in an arc shape, and the leg elastic members 5 for the front part P and the back part Q are Although it was made continuous, as shown in FIG. 1 3 (b), the elastic members 6 for the legs of the absorber are linearly bonded to both sides of the absorber 2, and the elasticity for the legs of the front portion P and the back portion Q is adhered. You may make it leave | separate from the member 5. FIG.
[0073]
Further, as shown in FIG. 1 3 (c), the absorbent leg elastic member 6 intersects with the leg elastic member 5 of the front part P and the back part Q, or as shown in FIG. 1 3 (d). The body leg elastic member 6 may be abutted against the leg elastic member 5 of the front part P and the back part Q.
