Description

本発明は、パンツ型使い捨ておむつ等のパンツ型吸収性物品の製造方法に関する。   The present invention relates to a method for producing a pants-type absorbent article such as a pants-type disposable diaper.

従来、パンツ型使い捨ておむつとしては、吸収性本体と、該吸収性本体の非肌対向面側に配されて該吸収性本体を固定している外装体とを備え、着用者の前後方向に相当する縦方向とこれに直交する横方向とを有し、且つ着用時に着用者の腹側に配される腹側部及び背側に配される背側部を縦方向に有し、該外装体における該腹側部に位置する外装体腹側領域及び該背側部に位置する外装体背側領域それぞれの縦方向に沿う両側縁部どうしが接合されて一対のサイドシール部、ウエスト開口部及び一対のレッグ開口部が形成されているものが汎用されている。また、斯かる構成のパンツ型使い捨ておむつにおいて、吸収性本体の縦方向端部からの尿等の***液の漏れを防止する目的で、吸収性本体の縦方向端部の肌対向面を防漏シートで被覆することが行われている。   Conventionally, as a pants-type disposable diaper, it is provided with an absorbent main body and an exterior body that is arranged on the non-skin-facing surface side of the absorbent main body and fixes the absorbent main body, and corresponds to the wearer's front-rear direction The exterior body has a longitudinal direction and a lateral direction perpendicular to the longitudinal direction, and has a ventral side portion disposed on the abdomen side of the wearer and a dorsal side portion disposed on the back side in the longitudinal direction when worn. In which the side edges along the longitudinal direction of the exterior body ventral region located on the ventral side and the exterior body backside region located on the back side are joined together to form a pair of side seal portions, a waist opening, and What is formed with a pair of leg openings is widely used. Moreover, in the pants-type disposable diaper having such a configuration, the skin-facing surface at the longitudinal end of the absorbent main body is leak-proof for the purpose of preventing leakage of excretion fluid such as urine from the vertical end of the absorbent main body. Covering with a sheet is performed.

防漏シートを備えたパンツ型使い捨ておむつに関し、例えば特許文献１には、外装体を構成する外層シートの縦方向の長さを、同じく外装体を構成する内層シートのそれよりも長くしておき、両シート材を重ね合わせたときに、該外層シートにおける該内層シートの縦方向外側端部からの延出部を、該内層シート側に折り返し、その折り返しによって相対向した該延出部と該内層シートとの間に、吸収性本体の縦方向端部が配されている構成を具備するパンツ型使い捨ておむつが記載されている。   Regarding a pants-type disposable diaper provided with a leak-proof sheet, for example, Patent Document 1 discloses that the length of the outer layer sheet constituting the exterior body is longer than that of the inner layer sheet constituting the exterior body. When the two sheet materials are overlapped, the extended portion of the outer layer sheet from the outer edge in the longitudinal direction of the inner layer sheet is folded back to the inner layer sheet side, and The underpants type disposable diaper which comprises the structure by which the longitudinal direction edge part of an absorptive main body is distribute | arranged between the inner layer sheets is described.

このように、特許文献１に記載の防漏シートに関する技術は、２層構造の外装体の非肌対向面を形成する外層シートを、肌対向面を形成する内層シート側に折り返すことによって、防漏シートを形成するというものであるのに対し、特許文献２には、防漏シートとして外装体とは別体の固定シートを用い、吸収性本体の縦方向両端部の肌対向面を該固定シートでそれぞれ個別に被覆することが記載されている。この固定シートは、吸収性本体の縦方向両端部及びそれらの近傍に配されており、外装体の縦方向端部には配されていない。   As described above, the technique relating to the leak-proof sheet described in Patent Document 1 folds the outer layer sheet that forms the non-skin facing surface of the two-layered exterior body to the inner layer sheet side that forms the skin facing surface, thereby preventing the leakage. In contrast to forming a leakage sheet, Patent Document 2 uses a fixing sheet separate from the exterior body as the leakage prevention sheet, and fixes the skin facing surfaces at both longitudinal ends of the absorbent main body. It is described that each sheet is individually coated. The fixing sheet is disposed at both longitudinal end portions of the absorbent main body and the vicinity thereof, and is not disposed at the longitudinal end portion of the exterior body.

特表２００８−５０８０８２号公報Special table 2008-508082 特開２０１１−９８０６２号公報JP 2011-98062 A

前記防漏シートを配置する主たる目的は、吸収性本体の縦方向端部からの漏れ防止であるから、その目的を達成するには、吸収性本体の縦方向端部及びその近傍を前記防漏シートで被覆すれば十分であるところ、特許文献１に記載されているように、外装体を構成する外層シートを折り返して吸収性本体の縦方向端部を被覆する方法では、外装体における、吸収性本体の縦方向端部よりも縦方向外方に位置する部分の全域が、折り返された外層シート（防漏シート）で被覆されるため、吸収性本体の固定位置によっては、防漏シートが必要以上に大きくなって製造コストの点で不利である。また、外層シートを折り返す場合、その外層シートの流れ方向に相応の長さを有する、外層シートの折り返し専用のコンベア等の装置が必要となり、斯かる装置の使用が製造コストの点で不利に働くおそれがある。   Since the main purpose of disposing the leak-proof sheet is to prevent leakage from the longitudinal end of the absorbent main body, in order to achieve the purpose, the longitudinal end of the absorbent main body and the vicinity thereof are connected to the leak-proof sheet. Where it is sufficient to cover with the sheet, as described in Patent Document 1, the method of folding the outer layer sheet constituting the exterior body and covering the longitudinal end of the absorbent main body absorbs the absorption in the exterior body. Because the entire area of the portion located longitudinally outward from the longitudinal end of the absorbent main body is covered with the folded outer layer sheet (leakproof sheet), depending on the fixing position of the absorbent main body, the leakproof sheet may be It becomes disadvantageous in terms of manufacturing cost because it becomes larger than necessary. Further, when the outer layer sheet is folded, a device such as a conveyor exclusively for folding the outer layer sheet having a length corresponding to the flow direction of the outer layer sheet is required, and the use of such a device is disadvantageous in terms of manufacturing cost. There is a fear.

これに対し、特許文献２に記載されているように、防漏シートとして外装体とは別体のシートを用い、吸収性本体の縦方向端部及びその近傍（吸収性本体の縦方向端部からの漏れ防止を達成するために防漏シートで被覆するべき部分）を被覆した場合には、外装体とは別に、防漏シート原反専用のシート巻き出し機が必要となり、更には、その巻き出し機を始点とする防漏シート原反専用のパスラインが必要となるため、設備コストがかさみ、製造コストの高騰を招くおそれがある。また、巻き出し機によって巻き出された防漏シート原反が、吸収性本体の縦方向一端部側に配されるものと他端部側に配されるものとを含む場合には、該防漏シート原反をスリッターで巻き出し方向に沿って二分割し、その二分割された細幅の防漏シート原反それぞれに所定のテンションをかけて専用のパスラインを走行させる工程が必要となるところ、そのような細幅の防漏シート原反に所定のテンションをかけた状態で長い距離引っ張ると、該防漏シート原反が幅縮みを起こし、製品品質の低下を招くおそれがある。   On the other hand, as described in Patent Document 2, a sheet separate from the exterior body is used as a leak-proof sheet, and the longitudinal end of the absorbent main body and its vicinity (the vertical end of the absorbent main body). In addition to the exterior body, a sheet unwinding machine dedicated to the raw material of the leakproof sheet is required. Since a path line dedicated to the raw material of the leak-proof sheet starting from the unwinding machine is required, the equipment cost is increased, and the manufacturing cost may increase. In addition, when the leak-proof sheet raw material unwound by the unwinding machine includes the one arranged on the one end side in the longitudinal direction and the other arranged on the other end side of the absorbent main body, It is necessary to divide the leaked sheet raw material into two along the unwinding direction with a slitter, and to run a dedicated pass line by applying a predetermined tension to each of the two divided narrow leakproof sheet raw materials. However, when such a narrow leak-proof sheet original fabric is pulled for a long distance in a state where a predetermined tension is applied, the original leak-proof sheet fabric may be reduced in width, resulting in a decrease in product quality.

従って、本発明は、吸収性本体の縦方向端部からの漏れが効果的に防止されたパンツ型吸収性物品を低コストで効率良く安定的に製造し得るパンツ型吸収性物品の製造方法に関する。   Therefore, the present invention relates to a method for producing a pant-type absorbent article that can efficiently and stably produce a pant-type absorbent article in which leakage from the longitudinal end portion of the absorbent main body is effectively prevented. .

本発明は、吸収性本体と、該吸収性本体の非肌対向面側に配されて該吸収性本体を固定している外装体とを備え、着用者の前後方向に相当する縦方向とこれに直交する横方向とを有し、且つ着用時に着用者の腹側に配される腹側部及び背側に配される背側部を縦方向に有し、該外装体における該腹側部に位置する外装体腹側領域及び該背側部に位置する外装体背側領域それぞれの縦方向に沿う両側縁部どうしが接合されて一対のサイドシール部、ウエスト開口部及び一対のレッグ開口部が形成されており、前記吸収性本体の縦方向両端部の肌対向面が、前記外装体とは別体の被覆体によってそれぞれ個別に被覆されているパンツ型吸収性物品の製造方法であって、走行中の１枚の帯状の原反シートにその走行方向に沿って切れ目を入れ、前記外装体を構成する外装体構成シートと、前記被覆体を構成する被覆体構成シートとに切り分ける原反シート切断工程と、前記原反シート切断工程で切り分けられた各シートを前記吸収性本体と接合する本体接合工程と、を有するパンツ型吸収性物品の製造方法を提供するものである。   The present invention comprises an absorbent main body and an exterior body that is arranged on the non-skin-facing surface side of the absorbent main body and fixes the absorbent main body, and a longitudinal direction corresponding to the front-rear direction of the wearer, and this The ventral side portion of the exterior body has a ventral side portion disposed on the abdomen side of the wearer when worn and a dorsal side portion disposed on the dorsal side in the longitudinal direction. A pair of side seal portions, a waist opening portion, and a pair of leg openings are joined to each other along the longitudinal direction of the exterior body ventral region located at the back and the exterior body back side region located at the back side Is formed, and the skin facing surfaces of both ends in the longitudinal direction of the absorbent main body are individually coated with a covering body separate from the exterior body.

Configuration 3: The outer layer sheet 35 and the inner layer sheet 36 each form a plurality of ridges that continuously extend over the plurality of elastic members 33 in the natural state of the exterior body 3.

次いで、図５に示すように、前記原反シート切断工程で切り分けられた帯状の外装体構成シート１１を、複数本の弾性部材３３が配された状態を維持したままで、その走行方向ＭＤに沿う折曲線１１Ｌにて折り曲げる（折曲工程）。第１実施態様においては、外装体構成シート１１の走行方向ＭＤに沿う両側縁１１ｓ，１１ｓそれぞれを、シート１１を幅方向に二分する仮想中心直線ＣＬに一致させるように折り曲げ、こうして折り曲げられることによって相対向する２枚のシート１１，１１間に、複数本の弾性部材３３を介在配置させる。これにより、２枚のシート１１，１１間に複数本の弾性部材３３が伸長状態で固定された帯状の複合シート１３が得られる。この帯状の複合シート１３は、帯状の腹側シート部材３１（外装体腹側領域）と帯状の背側シート部材３２（外装体背側領域）とを含み、両シート部材３１，３２は幅方向ＣＤに連続している。   Next, as shown in FIG. 5, the strip-shaped exterior body constituting sheet 11 cut in the original fabric sheet cutting step is maintained in the traveling direction MD while maintaining the state in which the plurality of elastic members 33 are arranged. Bend along the folding line 11L (bending process). In the first embodiment, the both side edges 11s, 11s along the traveling direction MD of the exterior body constituting sheet 11 are folded so as to coincide with the virtual center straight line CL that bisects the sheet 11 in the width direction, and thus folded. A plurality of elastic members 33 are interposed between the two opposing sheets 11, 11. Thereby, the strip | belt-shaped composite sheet 13 with which the several elastic member 33 was fixed in the expansion | extension state between the two sheets 11 and 11 is obtained. The strip-shaped composite sheet 13 includes a strip-shaped ventral sheet member 31 (exterior body ventral region) and a strip-shaped dorsal sheet member 32 (exterior body backside region). Continuing on CD.

こうして得られた帯状の複合シート１３に対し、必要に応じ、弾性部材３３のカット処理（非伸縮化処理）を施しても良い。弾性部材３３のカット処理は、例えば、複数の凸部を形成させたカットロールとアンビルロール等の公知の弾性部材カット手段（図示せず）を用いて、複合シート１３における吸収性本体２の配置領域に位置する該複合シート１３内に配置された弾性部材３３を押圧して、該弾性部材３３の収縮機能が発現されないように個々複数個に分断することにより実施することができる。   The strip-shaped composite sheet 13 obtained in this way may be subjected to a cutting process (non-stretching process) of the elastic member 33 as necessary. The cutting process of the elastic member 33 is, for example, the arrangement of the absorbent main body 2 in the composite sheet 13 using a known elastic member cutting means (not shown) such as a cut roll and an anvil roll formed with a plurality of convex portions. It can be carried out by pressing the elastic member 33 arranged in the composite sheet 13 located in the region and dividing it into a plurality of pieces so that the contraction function of the elastic member 33 is not expressed.

次いで、図５に示すように、帯状の複合シート１３（折り曲げられた外装体構成シート１１）に、スリッター等の公知の切断手段（図示せず）を用いてその走行方向ＭＤに沿って切れ目を入れ、帯状の腹側シート部材３１（腹側用部材１１Ａ）と帯状の背側シート部材３２（背側用部材１１Ｂ）とに切り分けつつ（外装体構成シート切断工程）、切り分けられた両部材３１，３２の間隔を、製造目的物であるおむつ１における両部材３１，３２の間隔に一致するように拡げ、その間隔を拡げた状態のままで両部材３１，３２を同じ走行方向ＭＤに走行させ、前記本体接合工程に導入させる。尚、前記外装体構成シート切断工程において帯状の複合シート１３（外装体構成シート１１）の切れ目を入れる位置には、接着剤又は弾性部材３３が配されていないことが好ましい。   Next, as shown in FIG. 5, the band-shaped composite sheet 13 (folded exterior body constituting sheet 11) is cut along a running direction MD using a known cutting means (not shown) such as a slitter. In addition, while separating into a belt-like ventral sheet member 31 (abdominal member 11A) and a belt-like dorsal sheet member 32 (back member 11B) (exterior body constituting sheet cutting step), both the separated members 31 are separated. , 32 is widened to coincide with the distance between both members 31, 32 in the diaper 1, which is the manufacturing object, and both members 31, 32 are caused to travel in the same traveling direction MD with the space being widened. The main body joining step is introduced. In addition, it is preferable that the adhesive or the elastic member 33 is not arranged in the position which makes the cut | interruption of the strip | belt-shaped composite sheet 13 (exterior body structure sheet 11) in the said exterior body structure sheet cutting process.

一方、前記原反シート切断工程で切り分けられた帯状の被覆体構成シート１２は、吸収性本体２の縦方向一端部側（腹側部Ａ側の縦方向端部２Ａ側）に配される帯状の被覆体５（一端部側用部材）と、他端部側（背側部Ｂ側の縦方向端部２Ｂ側）に配される帯状の被覆体６（他端部側用部材）とが幅方向ＣＤに連続したものであるため、前記本体接合工程の前に、シート１２を両被覆体５，６に切り分ける。より具体的には図５に示すように、前記原反シート切断工程で切り分けられた帯状の被覆体構成シート１２に、スリッター等の公知の切断手段（図示せず）を用いてその走行方向ＭＤに沿って切れ目を入れ、帯状の被覆体５と帯状の被覆体６とに切り分けつつ（被覆体構成シート切断工程）、切り分けられた両被覆体５，６の間隔を、その後の加工（接着剤の塗布等）の実施がより容易となるような間隔に拡げ、その間隔を拡げた状態のままで両被覆体５，６を同じ走行方向ＭＤに走行させる。   On the other hand, the belt-like covering-constituting sheet 12 cut in the raw sheet cutting step is a belt-like shape arranged on one end side in the longitudinal direction of the absorbent main body 2 (on the longitudinal end portion 2A side on the ventral side A side). Cover 5 (one-end-side member) and a belt-like cover 6 (other-end-side member) disposed on the other end side (vertical end 2B side on the back side B side). Since it is continuous in the width direction CD, the sheet 12 is cut into both coverings 5 and 6 before the main body joining step. More specifically, as shown in FIG. 5, the travel direction MD is applied to the belt-shaped covering-constituting sheet 12 cut in the raw sheet cutting process by using a known cutting means (not shown) such as a slitter. A cut is made along the belt and cut into a belt-like covering body 5 and a belt-like covering body 6 (covering member-forming sheet cutting step), and the interval between the cut-off covering bodies 5 and 6 is further processed (adhesive) The coverings 5 and 6 are caused to travel in the same traveling direction MD while the distance is widened.

More specifically, as shown in FIG. 5, one surface of each of the belt-shaped coverings 5 and 6 cut from the belt-shaped covering member-constituting sheet 12 (the surface facing the abdominal sheet member 31 or the back sheet member 32). Then, an adhesive such as a hot melt adhesive is applied to the surface). The adhesive application pattern is not particularly limited, and is continuously applied to the traveling direction MD of the belt-shaped coverings 5 and 6, that is, even if the belt-shaped adhesive application region is continuous in the traveling direction MD. Alternatively, it may be applied intermittently with respect to the traveling direction MD, that is, a coating pattern in which a plurality of adhesive application areas are arranged at predetermined intervals in the traveling direction MD. Moreover, in the adhesive application area | region in these application | coating patterns, the adhesive agent may be apply | coated (what is called a solid application) to the whole region of this adhesive application area | region, or the adhesive agent may be applied discretely. . The latter discrete application of the adhesive can be performed by using, for example, a spray type application means as the adhesive application means 50.

前述したように、本実施態様の製造目的物であるおむつ１においては、被覆体５，６それぞれの縦方向Ｘに沿う両側縁部と該両側縁部に対向するおむつ１の他の構成部材〔外装体３（内層シート３６）〕との間、即ち、一対のサイドシール部Ｓ，Ｓに対応する部分には接着剤は塗布されないので、これに対応して本実施態様の製造方法においては、前記接着剤塗布工程において、帯状の被覆体５，６それぞれの一面に、接着剤塗布手段５０を用いて接着剤を、その走行方向ＭＤに対して間欠的に塗布する。斯かる接着剤の間欠的な塗布において、接着剤を塗布しない領域（走行方向ＭＤに隣接する２つの接着剤塗布領域の間に位置する領域）は、その後の工程においてサイドシール部Ｓの形成に利用される。   As described above, in the diaper 1 that is the manufacturing object of the present embodiment, both side edges along the longitudinal direction X of the coverings 5 and 6 and other components of the diaper 1 facing the side edges [ Since the adhesive is not applied between the outer body 3 (inner layer sheet 36)], that is, the portion corresponding to the pair of side seal portions S, S, in the manufacturing method of this embodiment correspondingly, In the adhesive application step, an adhesive is intermittently applied to one surface of each of the belt-like coverings 5 and 6 using the adhesive application means 50 in the running direction MD. In such intermittent application of the adhesive, the region where the adhesive is not applied (the region located between the two adhesive application regions adjacent to the traveling direction MD) is used to form the side seal portion S in the subsequent process. Used.

こうして接着剤が塗布された帯状の被覆体５（一端部側用部材）及び帯状の被覆体６（他端部側用部材）は、それぞれ、別途用意された帯状の腹側シート部材３１（腹側用部材１１Ａ）及び帯状の背側シート部材３２（背側用部材１１Ｂ）と共に、前記本体接合工程に導入される。前記本体接合工程の実施に先立ち、両シート部材３１，３２それぞれにおける所定部位（吸収性本体２が接合される部位、あるいは吸収性本体２の周辺部における被覆体５又は６との重なり部位等）には、必要に応じ、接着剤塗布手段５１を用いて接着剤を塗布しても良い。   The belt-like covering 5 (one-end-side member) and the belt-like covering 6 (other-end-side member) to which the adhesive has been applied in this way are respectively provided with the belt-like belly-side sheet member 31 (belly-side). Together with the side member 11A) and the belt-like back side sheet member 32 (back side member 11B), it is introduced into the main body joining step. Prior to carrying out the main body joining step, predetermined portions in both the sheet members 31 and 32 (a portion where the absorbent main body 2 is joined, an overlapping portion of the peripheral portion of the absorbent main body 2 with the covering 5 or 6, etc.) If necessary, an adhesive may be applied using the adhesive application means 51.

前記本体接合工程では、前記原反シート切断工程で切り分けられた各シートを、常法に従って別途製造された吸収性本体２と接合する。より具体的には、図５に示すように、幅方向ＣＤに所定間隔を置いて互いに平行な状態で走行方向ＭＤに走行する帯状の腹側シート部材３１及び帯状の背側シート部材３２に対し、複数の吸収性本体２を、両シート部材３１，３２を架け渡すように間欠的に供給すると共に、幅方向ＣＤに所定間隔を置いて互いに平行な状態で同じ走行方向ＭＤに走行する帯状の被覆体５，６を、吸収性本体２の上方から供給し、シート部材３１と被覆体５との間及びシート部材３２と被覆体６の間で吸収性本体２の縦方向（幅方向ＣＤ）の両端部を固定する。こうして帯状のおむつ連続体（吸収性物品連続体）１４が得られる。   In the main body bonding step, each sheet cut in the raw fabric sheet cutting step is bonded to the absorbent main body 2 separately manufactured according to a conventional method. More specifically, as shown in FIG. 5, with respect to the belt-like belly side seat member 31 and the belt-like back side seat member 32 that run in the running direction MD in a state parallel to each other with a predetermined interval in the width direction CD. In addition, the plurality of absorbent main bodies 2 are intermittently supplied so as to bridge both the sheet members 31 and 32, and travel in the same traveling direction MD in a state parallel to each other with a predetermined interval in the width direction CD. The coverings 5 and 6 are supplied from above the absorbent main body 2, and the longitudinal direction (width direction CD) of the absorbent main body 2 between the sheet member 31 and the covering body 5 and between the sheet member 32 and the covering body 6. Fix both ends of. In this way, a continuous diaper continuous body (absorbent article continuous body) 14 is obtained.

次いで、図５に示すように、帯状のおむつ連続体１４をその幅方向ＣＤに２つ折りし、２つ折りされた帯状のおむつ連続体１４の、腹側シート部材３１と背側シート部材３２との積層体３７におけるサイドシール部Ｓの形成予定部位に、接着剤、ヒートエンボス加工手段、超音波加工手段等の公知の接合手段を用いて、接合部１５を走行方向ＭＤに所定間隔を置いて複数形成する。しかる後、２つ折りされた帯状のおむつ連続体１４を各接合部１５にて切断することにより、複数個のおむつ１が連続的に得られる。斯かる切断によって形成された積層体３７の切断端部は、各おむつ１のサイドシール部Ｓとなる。尚、帯状のおむつ連続体１４の各サイドシール部Ｓの形成予定部位に形成される接合部１５の形態は特に制限されず、例えば、該形成予定部位を幅方向ＣＤに延びる連続線状若しくは破線状等の線状接合部１５を１本形成する形態、又は該線状接合部１５を走行方向ＭＤに所定間隔を置いて複数本（２本）形成する形態が挙げられる。１本の線状接合部１５を形成した場合には、通常、その後のおむつ連続体１４の切断工程では１本の該線状接合部１５にて該おむつ連続体１４が切断されるので、その切断端部（サイドシール部Ｓ）には、基本的に、腹側シート部材３１と背側シート部材３２との接合領域のみからなる。一方、２本の線状接合部１５，１５を走行方向ＭＤに間隔を置いて形成した場合には、通常、その後のおむつ連続体１４の切断工程ではこれら２本の線状接合部１５，１５間にて該おむつ連続体１４が切断されるので、その切断端部（サイドシール部Ｓ）には、両シート部材３１，３２の接合領域が含まれない場合がある。   Next, as shown in FIG. 5, the belt-like diaper continuous body 14 is folded in two in the width direction CD, and the two-folded belt-like diaper continuous body 14 of the ventral side sheet member 31 and the back side sheet member 32 is A plurality of joining portions 15 are arranged at predetermined intervals in the traveling direction MD by using known joining means such as an adhesive, heat embossing means, ultrasonic processing means, etc., at the site where the side seal portion S is to be formed in the laminate 37.
