Description

本発明は着用物品の製造方法に関する。   The present invention relates to a method for manufacturing a worn article.

従来より、複数の互いに切り離されていないオムツ本体を連続して搬送し、該オムツ本体の腹側と背側の各側部にサイド部材を接合し、オムツ本体ごとに切り離した後、股部で該オムツ本体を折り畳み、腹側のサイド部材と背側のサイド部材とを互いに接合するパンツ型のオムツの製造方法が提案されている（特許文献１，特許文献２参照）。
特開平１０−１３７２８８号（要約書） 特開平７−８００２３号（図１） Conventionally, a plurality of unseparated diaper bodies are continuously conveyed, side members are joined to the abdomen and dorsal sides of the diaper body, and separated for each diaper body. There has been proposed a manufacturing method of a pants-type diaper in which the diaper main body is folded and the abdominal side member and the back side member are joined to each other (see Patent Document 1 and Patent Document 2).
JP-A-10-137288 (abstract) Japanese Patent Laid-Open No. 7-80023 (FIG. 1)

前記特許文献１では、腹側と背側のサイド部材同士を互いに接合するので、サイド部材同士の接合部分が着用者の腰の脇に形成される。そのため、前記接合部分が外側に突出して外観が悪くなり、また、着用者が横寝した場合には剛性の高い前記接合部分が着用者の腰脇に強く接触するため、着用者に不快感を与える。   In Patent Document 1, since the abdomen and dorsal side members are joined to each other, a joined portion between the side members is formed on the side of the wearer's waist. For this reason, the joint portion protrudes outwardly and the appearance is deteriorated.When the wearer lies down, the highly rigid joint portion strongly contacts the wearer's waist, which causes discomfort to the wearer. give.

前記特許文献２では、フロント部とバック部とをファスナを備えたサイド部材によって接合している。これにより、パンツ型着用物品が生成される。
しかし、前記サイド部材に形成された接合部分が外側に突出しており、そのため、前記特許文献１と同様の欠点が生じる。 In the said patent document 2, the front part and the back part are joined by the side member provided with the fastener. Thereby, a pants-type wearing article is generated.
However, the joint portion formed on the side member protrudes outward, and as a result, the same defects as in Patent Document 1 occur.

したがって、本発明の目的は、見栄えが良く、着用者が横寝した場合にも着用感が良好な着用物品の製造方法を提供することである。   Accordingly, an object of the present invention is to provide a method for producing a worn article that has a good appearance and a good wearing feeling even when the wearer lies down.

前記目的を達成するために、本発明のある着用物品の製造方法は、着用者の腹側を覆うフロント部、着用者の背側を覆うバック部、ならびに、前記フロント部とバック部との間の股部を有するオムツ本体と、前記フロント部と前記バック部との間に胴回り方向に架設されて着用者の胴にフィットするウエスト開口および着用者の脚が通る一対の脚開口を形成する一対のサイド部材とを備えた使い捨て着用物品の製造方法であって、前記胴回り方向に直交する縦方向に前記オムツ本体を搬送する工程と、前記フロント部またはバック部の一方における着用者の肌に接しない非肌面の前記胴回り方向の各側部にそれぞれ前記サイド部材の前記胴回り方向の第１端部を重ねると共に接合する第１接合工程と、前記各サイド部材を折り返すことで、前記各サイド部材の前記胴回り方向の第２端部を前記フロント部またはバック部の前記一方における着用者の肌に接する肌面の前記胴回り方向の各側部に重ねる工程と、前記フロント部と前記バック部とが互いに重なるように前記オムツ本体を前記股部において折り畳むことで、前記フロント部またはバック部の他方における着用者の肌に接する肌面の前記胴回り方向の各側部にそれぞれ前記折り返したサイド部材の前記第２端部を重ねて接合する第２接合工程とを備えている。   In order to achieve the above object, a method for manufacturing a wearing article according to the present invention includes a front part covering the abdomen side of the wearer, a back part covering the back side of the wearer, and between the front part and the back part. A pair of diapers having a crotch portion, a waist opening which is installed between the front portion and the back portion in a waistline direction to fit the wearer's torso and a pair of leg openings through which the wearer's leg passes A disposable wearing article comprising: a step of transporting the diaper main body in a longitudinal direction perpendicular to the waistline direction; and a skin of the wearer in one of the front part or the back part. A first joining step in which the first end portion of the side member in the waist direction is overlapped and joined to each side portion in the waist direction of the non-skin surface, and by folding each side member, A step of overlapping a second end portion of each side member in the waistline direction on each side portion of the skin surface in contact with the skin of the wearer in the one of the front portion or the back portion, the front portion and the back The diaper main body is folded at the crotch so that the lap is overlapped with each other, so that the side of the skin surface that contacts the wearer's skin on the other of the front part or the back part is folded back to each side part in the waistline direction. And a second joining step for joining the second end portions of the members in an overlapping manner.

本発明によれば、予め折り重ねたサイド部材をフロント部とバック部との間に架設するので、腰脇に接合部分が生じない。そのため、着用時に前記接合部分が外側に突出することがない。したがって、外観が良好になる。
また、腰脇に接合部分が存在しないので、着用者が横寝した場合でも前記接合部分が着用者の腰脇部分に当たることがない。したがって、着用感が良好になる。 According to the present invention, since the side member folded in advance is installed between the front portion and the back portion, no joint portion is formed on the waist side. Therefore, the joint portion does not protrude outward when worn. Therefore, the appearance is improved.
Moreover, since there is no joint part on the waist side, even when the wearer lies down, the joint part does not hit the waist side part of the wearer. Therefore, a feeling of wearing becomes good.

ここで、オムツ本体を２つに折り畳んだ後に、当該オムツ本体にサイド部材を接合しようとすると、オムツ本体が部位によって厚みにバラツキがあるため、サイド部材をオムツ本体に貼り付けにくい。これに対し、本製造方法では２つに折り畳む前のオムツ本体にサイド部材を貼り付けるので、サイド部材をオムツ本体に貼り付け易い。   Here, when the diaper main body is folded in two and then the side member is joined to the diaper main body, the diaper main body has a variation in thickness depending on the portion, and therefore, the side member is difficult to stick to the diaper main body. On the other hand, in this manufacturing method, since a side member is affixed to the diaper main body before folding in two, it is easy to affix a side member to a diaper main body.

また、オムツ本体を２つに折り畳む前にサイド部材がオムツ本体に重なるようにサイド部材を折り返すので、製造の際において、オムツ本体の側部からサイド部材が大きく張り出した状態を解消し得る。そのため、サイド部材の折り返しと、オムツ本体の折り畳みが容易になる。   Further, since the side member is folded back so that the side member overlaps the diaper main body before the diaper main body is folded in two, it is possible to eliminate the state in which the side member largely protrudes from the side portion of the diaper main body during manufacturing. Therefore, the side member can be folded and the diaper body can be folded easily.

本発明において、前記サイド部材の前記第２端部を前記一方の前記各側部に重ねる工程の前に、前記サイド部材の前記第１端部と前記第２端部との間の中間部において、前記サイド部材を複数回折り返す工程を更に備えているのが好ましい。
この態様によれば、サイド部材を複数回折り返すことで、サイド部材がオムツ本体の両側から大きく張り出すことなく、サイド部材の長さを長くすることができる。 In the present invention, before the step of overlapping the second end portion of the side member on the one side portion, the intermediate portion between the first end portion and the second end portion of the side member. Preferably, the method further comprises a step of turning back the side member a plurality of times.
According to this aspect, the length of the side member can be increased by bending the side member a plurality of times without causing the side member to largely protrude from both sides of the diaper main body.

本発明において、前記サイド部材の前記第２端部が前記一方の前記各側部に重ねられた部位において前記第２端部が前記一方の前記各側部に仮止めされているのが好ましい。
この態様によれば、サイド部材の第２端部を仮止めすることにより、サイド部材が折り返された状態が確実に維持される。そのため、オムツ本体にサイド部材の第２端部を重ねて接合する第２接合工程を容易、かつ、正確に行うことができる。 In the present invention, it is preferable that the second end portion is temporarily fixed to the one side portion at a portion where the second end portion of the side member is overlapped with the one side portion.
According to this aspect, the state where the side member is folded back is reliably maintained by temporarily fixing the second end of the side member. Therefore, the 2nd joining process which piles up and joins the 2nd end part of a side member on a diaper main body can be performed easily and correctly.

本発明において、前記サイド部材と前記第１端部とは面ファスナで互いに接合されており、前記第１接合工程において前記フロント部またはバック部の一方の各側部に前記サイド部材の前記第１端部が押し付けられるのが好ましい。
この態様によれば、予めパンツ型に形成された着用物品を製造することができると共に、前記サイド部材を前記第１端部から剥がし、着用者の体型に応じてオムツ本体に対するサイド部材の接合位置を変更することで、着用物品を着用者の胴回りにフィットさせることができる。 In the present invention, the side member and the first end are joined to each other by a hook-and-loop fastener, and the first of the side member is placed on each side of the front portion or the back portion in the first joining step. It is preferred that the end is pressed.
According to this aspect, it is possible to manufacture a wearing article formed in a pant shape in advance, and the side member is peeled off from the first end portion, and the joining position of the side member to the diaper main body according to the wearer's body shape By changing, the worn article can be fitted around the waist of the wearer.

本発明において、前記サイド部材は前記胴回り方向に伸縮する素材で形成されているのが好ましい。サイド部材が伸縮性を有する場合、着用物品のフィット性が向上する。   In the present invention, the side member is preferably formed of a material that expands and contracts in the waistline direction. When the side member has elasticity, the fit of the worn article is improved.

以下、本発明の実施例を図面にしたがって説明する。
図１は実施例１を示す。
オムツ１：
図１（ｆ）および図１（ｇ）に示すように、本実施例１の製造方法によって製造されるオムツ（着用物品の一例）１は、オムツ本体２とサイド部材３とを備えている。前記オムツ本体２は、着用者の腹側を覆うフロント部２０、着用者の背側を覆うバック部２１、ならびに、前記フロント部２０とバック部２１との間の股部２２を有している。 Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a first embodiment.
Diaper 1:
As shown in FIG. 1 (f) and FIG. 1 (g), a diaper (an example of a worn article) 1 manufactured by the manufacturing method of the first embodiment includes a diaper main body 2 and a side member 3. The diaper main body 2 has a front part 20 that covers the stomach side of the wearer, a back part 21 that covers the back side of the wearer, and a crotch part 22 between the front part 20 and the back part 21. .

前記サイド部材３は、たとえば、胴回り方向Ｙに伸縮する素材で形成されている。サイド部材３は、オムツ本体２のフロント部２０とバック部２１との間に胴回り方向Ｙに架設されている。オムツ本体２およびサイド部材３によって、着用者のウエスト開口２ｕおよび着用者の脚が通る一対の脚開口２３が形成されている。   The side member 3 is made of a material that expands and contracts in the waistline direction Y, for example. The side member 3 is installed in the waistline direction Y between the front part 20 and the back part 21 of the diaper main body 2. The diaper main body 2 and the side member 3 form a pair of leg openings 23 through which the wearer's waist opening 2u and the wearer's legs pass.

図１（ｇ）に示すように、サイド部材３の前記第１端部３１の裏面３ｂには雄面ファスナ４が設けられ、フロント部２０の非肌面２ａには雄面ファスナ４に互いに係合する雌面ファスナ６が設けられている。前記雌面ファスナ６と雄面ファスナ４とが互いに係合していることで、前記オムツ本体２の非肌面２ａにサイド部材３の第１端部３１が接合されている。サイド部材３の第２端部３２の表面３ａと、バック部２１の肌面２ｂとは互いに接着されている。前記第２端部３２の裏面３ｂとフロント部２０の肌面２ｂとは互いに仮止めされている。
なお、図１（ａ）および図１（ｆ）に示すように、前記雌面ファスナ６はオムツ本体２のフロント部２０に雌面ファスナ用の部材が接着されて構成されてもよいが、不織布からなる外装材で形成されてもよい。 As shown in FIG. 1 (g), a male fastener 4 is provided on the back surface 3 b of the first end portion 31 of the side member 3, and the male skin fastener 4 is engaged with the non-skin surface 2 a of the front portion 20. A mating female face fastener 6 is provided. The first end 31 of the side member 3 is joined to the non-skin surface 2a of the diaper main body 2 by the female surface fastener 6 and the male surface fastener 4 engaging with each other. The surface 3a of the second end portion 32 of the side member 3 and the skin surface 2b of the back portion 21 are bonded to each other. The back surface 3b of the second end portion 32 and the skin surface 2b of the front portion 20 are temporarily fixed to each other.
As shown in FIGS. 1 (a) and 1 (f), the female surface fastener 6 may be configured by bonding a member for female surface fasteners to the front portion 20 of the diaper main body 2. You may form with the exterior material which consists of.

このように、図１（ｇ）に示すオムツ本体２のフロント部２０とバック部２１とは、肌面２ｂ同士が互いに対面するように折り畳まれており、サイド部材３の第１および第２端部３１，３２はそれぞれフロント部２０およびバック部２１に接合されている。したがって、本実施例１のオムツ１は、図１（ｆ）および図１（ｇ）に示すように、ウエスト開口２ｕおよび脚開口２３を備えたパンツ型に予め形成されている。   Thus, the front part 20 and the back part 21 of the diaper main body 2 shown in FIG. 1 (g) are folded so that the skin surfaces 2b face each other, and the first and second ends of the side member 3 The parts 31 and 32 are joined to the front part 20 and the back part 21, respectively. Therefore, the diaper 1 of the first embodiment is formed in advance in a pants shape having a waist opening 2u and a leg opening 23 as shown in FIGS. 1 (f) and 1 (g).

前記パンツ型のオムツ１を着用するには、サイド部材３の第２端部３２とオムツ本体２のフロント部２０との仮止めを外し、ウエスト開口２ｕを広げて着用する。   In order to wear the pant-type diaper 1, the temporary fixing between the second end portion 32 of the side member 3 and the front portion 20 of the diaper main body 2 is removed, and the waist opening 2 u is widened and worn.

前記オムツ１のウエスト開口２ｕの大きさが着用者の胴にフィットしない場合がある。かかる場合には、サイド部材３の雄面ファスナ４をオムツ本体２のフロント部２０から剥した後、ウエスト開口２ｕの大きさが着用者の胴にフィットするように雄面ファスナ４をフロント部２０の雌面ファスナ６に接合する。   The size of the waist opening 2u of the diaper 1 may not fit the wearer's torso. In such a case, after peeling off the male fastener 4 of the side member 3 from the front part 20 of the diaper main body 2, the male fastener 4 is fitted to the front part 20 so that the size of the waist opening 2u fits the wearer's torso. The female surface fastener 6 is joined.

つぎに、前記パンツ型オムツ１の製造方法について説明する。
図１（ａ）および図５に示すように、複数のオムツ本体２が互いに連なった（切り離されていない）連続ウエブＷの状態でオムツ本体２が搬送される。前記連続ウエブＷは、たとえば、連続する積層シートからなり、胴回り方向Ｙに略直交する縦方向（搬送方向）Ｘに搬送される。 Below, the manufacturing method of the said underpants type diaper 1 is demonstrated.
As shown in FIG. 1A and FIG. 5, the diaper body 2 is conveyed in a state of a continuous web W in which a plurality of diaper bodies 2 are connected to each other (not separated). The continuous web W is made of, for example, continuous laminated sheets and is conveyed in a longitudinal direction (conveying direction) X substantially orthogonal to the waistline direction Y.

前記オムツ本体２には、着用者の股間を覆う吸収性本体５などが設けられる。図５に示すように、前記連続ウエブＷは、トップシートＳｔとバックシートＳｂとの間に吸収性本体５が設けられてもよい。なお、トップシートＳｔはオムツ本体２の非肌面２ａを形成し、一方、バックシートＳｂはオムツ本体２の肌面２ｂを形成する。
また、図１（ａ）に示すオムツ本体２のフロント部２０の非肌面（外面）２ａ側には、雌面ファスナ６が接着されてもよい。 The diaper main body 2 is provided with an absorbent main body 5 that covers the crotch of the wearer. As shown in FIG. 5, the continuous web W may be provided with an absorbent main body 5 between the top sheet St and the back sheet Sb. The top sheet St forms the non-skin surface 2a of the diaper main body 2, while the back sheet Sb forms the skin surface 2b of the diaper main body 2.
Moreover, the female surface fastener 6 may be adhere | attached on the non-skin surface (outer surface) 2a side of the front part 20 of the diaper main body 2 shown to Fig.1 (a).

サイド部材３を切断する工程：
一方、雄面ファスナ４を有するサイド部材３が、オムツ本体２の側部２ｓに対応するように一対づつ搬送される。すなわち、図５に示す連続した伸縮する素材からなるシートＳ２が、図示しないカッタによって個々のサイド部材３に切断され、搬送ローラ３０によって所定の間隔に離間されて搬送される。
なお、図１（ｂ）に示すように、前記雄面ファスナ４はサイド部材３の裏面３ｂに貼着されている。 Step of cutting the side member 3:
On the other hand, the side members 3 having the male fasteners 4 are conveyed pair by pair so as to correspond to the side portions 2s of the diaper main body 2. That is, the sheet S2 made of a continuously expanding and contracting material shown in FIG. 5 is cut into individual side members 3 by a cutter (not shown), and is conveyed at a predetermined interval by the conveying roller 30.
In addition, as shown in FIG.1 (b), the said male surface fastener 4 is affixed on the back surface 3b of the side member 3. As shown in FIG.

第１接合工程：
その後、各サイド部材３の第１端部３１がオムツ本体２のフロント部２０にそれぞれ接合される。すなわち、前記フロント部２０における非肌面２ａの胴回り方向Ｙの各側部２ｓに、それぞれ、サイド部材３の胴回り方向Ｙの第１端部３１が重ねられてサイド部材３がフロント部２０に接合される。
当該接合は、図５に示す押圧ローラ７によって、図１（ｂ）に示すようにサイド部材３の雄面ファスナ４がオムツ本体２（連続ウエブＷ）の雌面ファスナ６に押し付けられることにより行われる。 First joining step:
Then, the 1st end part 31 of each side member 3 is joined to the front part 20 of the diaper main body 2, respectively. In other words, the first end portion 31 of the side member 3 in the waist direction Y of the side member 3 is overlapped on each side portion 2s of the front surface 20 in the waist direction Y of the non-skin surface 2a, and the side member 3 is joined to the front portion 20. Is done.
The joining is performed by pressing the male fastener 4 of the side member 3 against the female fastener 6 of the diaper main body 2 (continuous web W) by the pressing roller 7 shown in FIG. 5 as shown in FIG. Is called.

サイド部材３を折り返すことで各側部２ｓに重ねる工程：
その後、図５に示す折り装置８によって、図１（ａ）および図１（ｃ）に示すように、各サイド部材３がオムツ本体２の肌面２ｂに対面するように折り返される。サイド部材３が折り返されることで、各サイド部材３の胴回り方向Ｙの第２端部３２が、前記フロント部２０における着用者の肌面２ｂの胴回り方向Ｙの各側部２ｓに重ねられる。 The process of folding the side member 3 over each side 2s:
Thereafter, each side member 3 is folded back by the folding device 8 shown in FIG. 5 so as to face the skin surface 2b of the diaper main body 2 as shown in FIGS. 1 (a) and 1 (c). By folding the side member 3, the second end portion 32 of each side member 3 in the waistline direction Y is overlapped with each side portion 2 s of the front surface 20 in the waistline direction Y of the skin surface 2 b of the wearer.

ここで、図１（ｃ）に示すように、当該工程において折られたサイド部材３の当該折り返された状態を維持するために、前記第２端部３２の裏面３ｂは前記各側部２ｓに重ねられた仮止め部３９においてオムツ本体２のフロント部２０の肌面２ｂに仮止めされる。
前記仮止めは、たとえば、超音波、ヒートシールやホットメルトなどによって行われる。なお、仮止めは点状になされ、オムツの着用時に容易に分離することができる。 Here, as shown in FIG. 1C, in order to maintain the folded state of the side member 3 folded in the step, the back surface 3b of the second end portion 32 is formed on the side portions 2s. The temporarily fixed portion 39 is temporarily fixed to the skin surface 2 b of the front portion 20 of the diaper main body 2.
The temporary fixing is performed by, for example, ultrasonic waves, heat sealing, hot melt, or the like. In addition, temporary fixing is made in the shape of a dot and can be easily separated when the diaper is worn.

ダイカット：
つぎに、図５に示すダイカッタ９により、図１（ｄ）および図１（ｅ）に示すオムツ本体２に着用者の脚部に沿ってカットされた脚開口２３が形成されてもよい。 Die cut:
Next, leg openings 23 cut along the wearer's legs may be formed in the diaper main body 2 shown in FIGS. 1 (d) and 1 (e) by the die cutter 9 shown in FIG.

切り分け工程：
その後、図１（ａ）に示す前記連続ウエブＷは、切り分けカッタ１０（図５）により、胴回り方向Ｙに概ね平行なカットラインＣＬに沿って、図１（ｄ）および図１（ｅ）に示すように、個々のオムツ本体２に切り分けられる。 Carving process:
Thereafter, the continuous web W shown in FIG. 1A is cut along the cut line CL substantially parallel to the waistline direction Y by the cutting cutter 10 (FIG. 5) in FIGS. 1D and 1E. As shown, it is cut into individual diaper bodies 2.

前記切り分け工程によって切り分けられたオムツ本体２は、図１（ｃ）に示すように、フロント部２０の非肌面２ａにサイド部材３の第１端部３１の裏面３ｂが雄面ファスナ４を介して接合されていると共に、フロント部２０の肌面２ｂにサイド部材３の第２端部３２の裏面３ｂが仮止めされている。   In the diaper main body 2 carved by the carving process, as shown in FIG. 1C, the back surface 3 b of the first end portion 31 of the side member 3 is disposed on the non-skin surface 2 a of the front portion 20 via the male fastener 4. The back surface 3b of the second end portion 32 of the side member 3 is temporarily fixed to the skin surface 2b of the front portion 20.

第２接合工程：
その後、図１（ｅ）の網点で示す部位に、つまり、サイド部材３の第２端部３２の表面３ａに接着剤が塗布され、図５に示す折り畳み装置１１によって、図１（ｅ）に示すオムツ本体２のフロント部２０とバック部２１の肌面２ｂ同士が対面するように互いに重ねられる。
なお、前記折り畳み装置１１としては、たとえば、特開平７−２０５９４３号に記載の折り畳み装置などを用いることができる。 Second joining step:
Thereafter, an adhesive is applied to the portion indicated by the halftone dots in FIG. 1E, that is, the surface 3a of the second end 32 of the side member 3, and the folding device 11 shown in FIG. The front part 20 of the diaper main body 2 and the skin surface 2b of the back part 21 are overlapped with each other so as to face each other.
As the folding device 11, for example, a folding device described in JP-A-7-205943 can be used.

前記折り畳みにより、図１（ｇ）に示すように、バック部２１における肌面２ｂの胴回り方向Ｙの各側部２ｓに、それぞれサイド部材３の第２端部３２が重ねられて接合（接着）される。   As shown in FIG. 1G, the second end portions 32 of the side members 3 are overlapped and bonded (adhered) to the side portions 2s of the skin surface 2b of the skin portion 2b in the waist direction Y by the folding. Is done.
