　使い捨ておむつや生理用ナプキンのような吸収性物品の製品形態の一つとして、吸収性物品が個別に包装された包装品を複数個一方向に連結してなる連結包装製品が知られている。その連結包装製品は例えば店頭に陳列され、購入者が希望する個数の包装品がその連結包装製品から切り離されて購入者へ販売される。 As one of the product forms of absorbent articles such as disposable diapers and sanitary napkins, a linked package product is known in which a plurality of packaged articles each having an absorbent article packaged are connected in one direction. The linked packaged product is displayed at, for example, a store, and a desired number of packages are purchased from the linked packaged product and sold to the purchaser.
　このような連結包装製品は、例えば、搬送方向に搬送される連続シート上に複数の吸収性物品を順次供給する工程と、その連続シートを筒状にして複数の吸収性物品が内包された筒状の連続シートを形成する工程と、その筒状の連続シートにおける互いに隣り合う吸収性物品同士の間を横断方向に挟んで接合する工程と、接合部分の中央を切断する工程とにより製造される。 Such a linked packaged product includes, for example, a step of sequentially supplying a plurality of absorbent articles onto a continuous sheet conveyed in the conveying direction, and a cylinder in which the continuous sheet is formed into a cylindrical shape and a plurality of absorbent articles are included. Of the cylindrical continuous sheet, the step of joining the absorbent articles adjacent to each other in the cylindrical continuous sheet in the transverse direction, and the step of cutting the center of the joint portion. .
　ここで、持ち運びや収納に便利であることや、包装袋のコストが削減できることなどから、吸収性物品の包装袋は小さいことが好ましい。吸収性物品の包装袋を小さくするには、その包装袋に挿入できるように吸収性物品を折り畳んで小さくする必要がある。しかし、吸収性物品は弾力性を有するため、折り畳まれると、折り畳まれていない元の状態に回復しようとする。そのため、吸収性物品の一部分を残りの部分の上に重ねるように吸収性物品を折り畳むと、その一部分が残りの部分から離れて上方にやや持ち上がった状態になる。そのとき、折り畳みの折り目の位置により、その一部分の持ち上がった状態にばらつきがでる場合が考えられ、その場合には折り畳まれた吸収性物品の厚さがばらつくおそれがある。そうなると、吸収性物品を連続シートで包装するとき、連続シート上に吸収性物品を載置できなかったり、連続シートを筒状に形成できなくなったりするおそれがある。特に搬送速度が高くなるほどその影響は大きくなる。 Here, the packaging bag of the absorbent article is preferably small because it is convenient to carry and store and the cost of the packaging bag can be reduced. In order to reduce the packaging bag of the absorbent article, it is necessary to fold the absorbent article so that it can be inserted into the packaging bag. However, since the absorbent article has elasticity, when it is folded, it attempts to recover the original unfolded state. Therefore, when the absorbent article is folded so that a part of the absorbent article is overlaid on the remaining part, the part is lifted slightly away from the remaining part. At that time, depending on the position of the folding fold, there may be a case where the lifted state of the part varies, and in this case, the thickness of the folded absorbent article may vary. Then, when the absorbent article is packaged with a continuous sheet, the absorbent article may not be placed on the continuous sheet, or the continuous sheet may not be formed into a cylindrical shape. In particular, the effect increases as the conveyance speed increases.
　厚みのばらつきが大きいときにも連続シート上に吸収性物品を載置し、連続シートを筒状に形成しようとすれば、筒の内側の寸法を大きくすることが考えられる。しかし、その場合、筒の内側の空間に余裕ができるため、何らかの外力により、筒状の連続シート内で吸収性物品が前後左右に動くことが可能となってしまう。すなわち筒状の連続シート内の吸収性物品の位置が不安定になってしまう。そうなると様々な不具合が発生するおそれがある。 If the absorbent article is placed on the continuous sheet and the continuous sheet is formed into a cylindrical shape even when the variation in thickness is large, it is conceivable to increase the inner dimension of the cylinder. However, in that case, since there is room in the space inside the cylinder, the absorbent article can move back and forth and right and left within the cylindrical continuous sheet by some external force. That is, the position of the absorbent article in the cylindrical continuous sheet becomes unstable. If this happens, various problems may occur.
　例えば、上記の接合する工程では、筒状の連続シートを接合する際に、筒状の連続シート内の空気の一部が搬送方向の上流側へ流れる。そのとき筒状の連続シート内の吸収性物品の位置が不安定であると吸収性物品の位置が空気の流れによりずれてしまい、その後の接合する工程で接合部分に吸収性物品を挟んでしまうおそれがある。 For example, in the above-described joining step, when joining the cylindrical continuous sheet, a part of the air in the cylindrical continuous sheet flows upstream in the conveying direction. At that time, if the position of the absorbent article in the cylindrical continuous sheet is unstable, the position of the absorbent article will be displaced by the flow of air, and the absorbent article will be sandwiched between the joining parts in the subsequent joining process. There is a fear.
　また、筒状の連続シート内の吸収性物品の位置が不安定であると、搬送の途中で吸収性物品の位置が前後左右にずれることが起こり得る。そうなると筒状の連続シートの重心の位置が適正な位置からずれてしまい、筒状の連続シートが搬送の途中で全体的に横断方向にずれたり、蛇行したり、折れ曲がったりするおそれがある。 In addition, if the position of the absorbent article in the cylindrical continuous sheet is unstable, the position of the absorbent article may shift from front to back and from side to side during conveyance. If this happens, the position of the center of gravity of the cylindrical continuous sheet is shifted from an appropriate position, and there is a possibility that the cylindrical continuous sheet may be shifted in the transverse direction, meandered, or bent in the course of conveyance.
　また、連結包装製品は複数の包装品が連結されているため梱包箱に密に梱包するのが難しい製品である。筒状の連続シート内の吸収性物品の位置が不安定であると、製造された連結包装製品の包装袋内でも吸収性物品が動き易くなる。そのため、連結包装製品が梱包箱に詰め込まれるときに包装袋内で吸収性物品が偏ってしまい密に梱包できなかったり、輸送などで梱包箱が揺さぶられるときに梱包箱内で包装品の配置が乱されたりし得る。その結果、包装品の一部が変形したり押し潰されたりして吸収性物品の吸収体が変形して吸収力が低下するおそれがある。 Also, the linked packaged product is a product that is difficult to pack tightly in a packing box because a plurality of packaged products are linked. If the position of the absorbent article in the cylindrical continuous sheet is unstable, the absorbent article can easily move even in the packaging bag of the manufactured linked packaged product. For this reason, when connected packaging products are packed in packing boxes, absorbent articles are biased in the packing bag and cannot be packed densely, or when the packing box is shaken during transportation, etc. It can be disturbed. As a result, part of the packaged product may be deformed or crushed, and the absorbent body of the absorbent article may be deformed, resulting in a decrease in absorbent power.
　連結包装製品の製造において、搬送中の吸収性物品の厚みのばらつきの影響を抑え、筒状の連続シート内の吸収性物品の位置を固定する、すなわち筒状の連続シート内の所定の位置に吸収性物品を位置決めができる技術が望まれる。 In the production of linked packaged products, the effect of variation in the thickness of the absorbent article being transported is suppressed, and the position of the absorbent article in the cylindrical continuous sheet is fixed, that is, at a predetermined position in the cylindrical continuous sheet. A technique capable of positioning an absorbent article is desired.

　連結包装製品の製造において、筒状の連続シート内の所定の位置に吸収性物品を位置決めする方法として、本発明の発明者は、吸収性物品の大きさを規制して筒状の連続シートに供給し、筒状の連続シート内で吸収性物品の大きさを回復させて連続シートが吸収性物品で突っ張った状態にする方法を考えた。 As a method for positioning an absorbent article at a predetermined position in a cylindrical continuous sheet in the manufacture of linked packaged products, the inventors of the present invention regulate the size of the absorbent article to form a cylindrical continuous sheet. A method was considered in which the size of the absorbent article was recovered in the cylindrical continuous sheet so that the continuous sheet was stretched by the absorbent article.
　特許文献１には、複数の紙製のモップシートが厚さ方向に積層された物品群を２個接触した製品をガイドベルトで圧縮しながら搬送して筒状に形成される連続シート内に挿入する技術が開示されている。しかしながら、上述の特許文献１の技術は、複数枚の物品（モップシート）を積層して一まとめにして包装した包装製品を対象としており、吸収性物品の包装品を複数個一方向に連結されてなる連結包装製品を対象とする本発明とは取り扱う製品が相違している。そのため、連結包装製品に固有の問題、例えば上述の筒状の連続シートが搬送の途中で蛇行等したり、梱包箱内で包装品が乱れたりすることについて何ら開示しておらず、連結包装製品の製造における吸収性物品の位置決めに対応できない。更に、上述の特許文献１の技術では、モップシートは圧縮されると膨らみやすいが軽量であるため、筒状の連続シートを内側から突っ張った状態にして位置決めをすることは困難である。すなわち、連結包装製品の製造における吸収性物品の位置決めに対応できない。 In Patent Document 1, a product obtained by contacting two article groups in which a plurality of paper mop sheets are laminated in the thickness direction is conveyed while being compressed by a guide belt and inserted into a continuous sheet formed into a cylindrical shape. Techniques to do this are disclosed. However, the technique of Patent Document 1 described above is intended for a packaged product in which a plurality of articles (mop sheets) are stacked and packaged together, and a plurality of packaged absorbent articles are connected in one direction. The product to be handled is different from the present invention for the connected packaged product. Therefore, there is no disclosure about problems inherent to linked packaging products, for example, the above-mentioned cylindrical continuous sheet meanders in the middle of conveyance or the packaging product is disturbed in the packaging box. It cannot respond to the positioning of the absorbent article in the manufacture of Furthermore, in the technique of the above-mentioned Patent Document 1, since the mop sheet is easy to swell when compressed, it is lightweight, and thus it is difficult to position the tubular continuous sheet in a state of stretching from the inside. That is, it cannot respond to the positioning of the absorbent article in the manufacture of the linked packaged product.
　本発明の目的は、連結包装製品の製造において、搬送中の吸収性物品の厚みのばらつきの影響を抑え、筒状の連続シート内の所定の位置に吸収性物品を位置決めが可能な連結包装製品の製造方法を提供することにある。 An object of the present invention is to provide a linked packaged product that can suppress the influence of variations in the thickness of the absorbent article being conveyed and can position the absorbent article at a predetermined position in a cylindrical continuous sheet in the production of the linked packaged product. It is in providing the manufacturing method of.
　本発明の連結包装製品の製造方法は次のとおりである。
　（１）複数の包装品が一方向に連結されてなる連結包装製品の製造方法であって、前記複数の包装品の各々は吸収性物品と前記吸収性物品を包装する包装袋とを含んでおり、前記連結包装製品の製造方法は、一方向に並んだ複数の前記吸収性物品を搬送方向に順次搬送しながら、前記吸収性物品を前記搬送方向に直交する上下方向に重なるように一回以上折り畳む折り畳み工程と、折り畳まれた前記複数の吸収性物品を前記搬送方向に順次搬送しながら、前記上下方向における前記吸収性物品の厚さを第１の寸法以下にする規制を行う規制工程と、前記搬送方向に搬送されつつ連続的に筒状に形成される連続シートの内側に、前記規制後の前記複数の吸収性物品を順次供給して包装する包装工程であって、前記筒状の前記連続シートにおける前記上下方向の内側の寸法が前記第１の寸法である包装工程と、前記複数の吸収性物品を内包した前記筒状の前記連続シートを前記搬送方向に搬送しながら、前記筒状の前記連続シートにおける互いに隣り合う吸収性物品同士の間の部分で筒内面の対向する前記連続シート同士を接合する接合工程と、を備える、連結包装製品の製造方法。 The manufacturing method of the linked packaged product of the present invention is as follows.
(1) A method for manufacturing a linked packaged product in which a plurality of packaged products are connected in one direction, each of the packaged products including an absorbent article and a packaging bag for packaging the absorbent article. And the manufacturing method of the linked packaged product is performed once so that the absorbent article is overlapped in the vertical direction perpendicular to the transport direction while sequentially transporting the absorbent articles arranged in one direction in the transport direction. A folding step that folds as described above, and a regulation step that regulates the thickness of the absorbent article in the vertical direction to be equal to or less than a first dimension while sequentially conveying the plurality of folded absorbent articles in the conveyance direction; A packaging step of sequentially supplying and packaging the plurality of the absorbent articles after the regulation inside a continuous sheet continuously formed into a cylindrical shape while being conveyed in the conveying direction, In the continuous sheet The packaging step in which the inner dimension in the vertical direction is the first dimension, and the cylindrical continuous sheet containing the plurality of absorbent articles while transporting the cylindrical continuous sheet in the transport direction. A joining step of joining the continuous sheets facing each other on the inner surface of the cylinder at a portion between the absorbent articles adjacent to each other in the sheet.
　折り畳まれた吸収性物品では折り目の位置のばらつきによっては、折り目に掛かる吸収体の量などが変わるので、上下方向の厚さのばらつきが発生し得る。ここで、本発明では、上下方向の厚さのばらつきにかかわらず、規制工程において上下方向の厚さを第１の寸法以下に規制するので、その後の包装工程において、上下方向の内側の寸法が第１の寸法である筒状の連続シートの内側に吸収性物品を確実に挿入することができる。規制工程において上下方向の厚さを第１の寸法以下に規制されると、包装工程において規制前の厚さ、すなわち第１の寸法より大きい寸法に回復しようと内側から外側に向かって拡がろうとする。しかし、筒状の連続シートにおける上下方向の内側の寸法は第１の寸法であり、吸収性物品における上下方向の規制前の寸法（第１の寸法より大きい寸法）よりも小さいので、筒状の連続シートが吸収性物品により内側から押し拡げられて突っ張った状態になる。その結果、吸収性物品が筒状の連続シートにより周囲から押さえ付けられ、動き難い状態となるので、それにより吸収性物品を筒状の連続シート内の所定の位置に確実に位置決めできる。すなわち吸収性物品を筒状の連続シート内の所定の位置に固定できる。
　吸収性物品が確実に位置決めされると、後工程の接合工程における筒状の連続シートの接合に伴って筒状の連続シート内の空気の一部が搬送方向の上流側へ流れてきても、筒状の連続シート内の吸収性物品の位置が上流側にずれ難くなる。それにより、接合工程において筒状連続シートにおける吸収性物品の間の部分で筒内面の対向する前記連続シート同士を接合するとき、筒状の連続シートの接合部分に吸収性物品を挟んでしまう、ということが無くなる。
　また、吸収性物品が確実に位置決めされると、筒状の連続シート内の吸収性物品がその位置から前後左右に動き難くなり、したがって筒状の連続シート内の吸収性物品の重心の位置が前後左右にずれ難くなる。それにより、複数の吸収性物品を内包しつつ搬送方向に搬送される筒状の連続シートが搬送方向に対して全体的に横断方向にずれたり、蛇行したり、折れ曲がったりすることが起こり難くなり、筒状の連続シートを搬送方向に安定して搬送することができる。
　また、吸収性物品が確実に位置決めされると、筒状の連続シート内の吸収性物品が前後左右に動き難くなるので、製造された連結包装製品においても吸収性物品が包装袋内で動き難くなる。それにより、連結包装製品をダンボール箱のような梱包箱に詰め込むとき、包装袋内で吸収性物品のずれがほとんどないため、包装品を梱包箱内に容易に整列させて配置することができる。それゆえ、輸送などで梱包箱が揺さぶられても、梱包箱内で包装品の配置が乱され難くなるので、包装品の一部が変形したり押し潰されたりして吸収性物品の吸収体が変形して吸収力が低下する、ということを防止できる。 In the folded absorbent article, the amount of the absorber applied to the fold changes depending on the fold position variation, and thus the thickness variation in the vertical direction may occur. Here, in the present invention, the thickness in the vertical direction is regulated to the first dimension or less in the regulating process regardless of the variation in the thickness in the vertical direction. The absorbent article can be surely inserted inside the cylindrical continuous sheet having the first dimension. When the thickness in the vertical direction is regulated to be equal to or less than the first dimension in the regulation process, the thickness before the regulation in the packaging process, that is, to increase from the inside to the outside in order to recover to a dimension larger than the first dimension. To do. However, the inner dimension in the vertical direction of the cylindrical continuous sheet is the first dimension, which is smaller than the dimension before the regulation in the vertical direction in the absorbent article (a dimension larger than the first dimension). The continuous sheet is stretched and stretched from the inside by the absorbent article. As a result, the absorbent article is pressed from the periphery by the cylindrical continuous sheet and becomes difficult to move, so that the absorbent article can be reliably positioned at a predetermined position in the cylindrical continuous sheet. That is, the absorbent article can be fixed at a predetermined position in the cylindrical continuous sheet.
When the absorbent article is reliably positioned, even if a part of the air in the cylindrical continuous sheet flows upstream in the conveying direction along with the joining of the cylindrical continuous sheet in the subsequent joining step, The position of the absorbent article in the cylindrical continuous sheet is difficult to shift upstream. Thereby, when joining the continuous sheets facing each other on the inner surface of the cylinder at the part between the absorbent articles in the cylindrical continuous sheet in the joining step, the absorbent article is sandwiched between the joined parts of the cylindrical continuous sheet. That disappears.
Further, when the absorbent article is reliably positioned, the absorbent article in the cylindrical continuous sheet is difficult to move back and forth and from side to side, and therefore the position of the center of gravity of the absorbent article in the cylindrical continuous sheet is It becomes difficult to shift back and forth and left and right. As a result, it is difficult for a cylindrical continuous sheet that is conveyed in the conveying direction while containing a plurality of absorbent articles to be displaced, meandered, or bent in the transverse direction as a whole with respect to the conveying direction. A cylindrical continuous sheet can be stably conveyed in the conveying direction.
In addition, when the absorbent article is securely positioned, the absorbent article in the cylindrical continuous sheet is difficult to move back and forth and from side to side. Therefore, the absorbent article is also difficult to move in the packaging bag even in the manufactured linked packaging product. Become. Accordingly, when the linked packaged product is packed in a packaging box such as a cardboard box, there is almost no displacement of the absorbent article in the packaging bag, and the packaged product can be easily aligned and arranged in the packaging box. Therefore, even if the packaging box is shaken during transportation, etc., the arrangement of the packaged item is less likely to be disturbed in the packaging box, so that part of the packaged product may be deformed or crushed and the absorbent body of the absorbent article Can be prevented from being deformed and lowering the absorption power.
　（２）前記折り畳み工程において、折り畳まれた前記吸収性物品の少なくとも一つの折り目が前記搬送方向及び前記上下方向に直交する横断方向に沿い且つ前記吸収性物品における前記搬送方向の下流側に配置されるように、前記吸収性物品を折り畳み、前記規制工程において、下側搬送ベルトにより、前記吸収性物品を前記搬送方向に搬送し、前記下側搬送ベルトの上方に前記下側搬送ベルトと対向して配置された上側規制手段と、前記下側搬送ベルトとの間に前記搬送方向の下流側の前記折り目が入るように前記吸収性物品を搬送することによって、前記上下方向の前記吸収性物品の厚さを規制する、上記（１）に記載の連結包装製品の製造方法。 (2) In the folding step, at least one fold of the folded absorbent article is disposed along a transverse direction perpendicular to the transport direction and the up-down direction and downstream of the absorbent article in the transport direction. The absorbent article is folded, and in the regulation step, the absorbent article is conveyed in the conveyance direction by the lower conveyance belt, and is opposed to the lower conveyance belt above the lower conveyance belt. Of the absorbent article in the up-down direction by conveying the absorbent article so that the fold on the downstream side in the conveyance direction enters between the upper regulating means arranged in a row and the lower conveyance belt. The method for producing a linked packaged product according to (1), wherein the thickness is regulated.
　搬送方向の下流側に折り目が位置するように吸収性物品を折り畳んでいるので、厚さにばらつきがあっても吸収性物品を折り目の側から下側搬送ベルトと上側規制手段との間に容易に挿入でき、上側規制手段の位置が固定的であるときには更に折り畳まれた部分が捲れ上がることを抑制でき、それにより、吸収性物品の上下方向の厚さを所定の寸法以下に容易に規制することができる。 Since the absorbent article is folded so that the crease is positioned on the downstream side in the conveyance direction, the absorbent article can be easily placed between the lower conveyance belt and the upper regulating means from the crease side even if the thickness varies. When the position of the upper restricting means is fixed, it is possible to suppress the folded portion from further rolling up, thereby easily restricting the thickness in the vertical direction of the absorbent article to a predetermined dimension or less. be able to.
　（３）前記上側規制手段は、前記搬送方向に延在しており、前記下側搬送ベルトと前記上側規制手段との間の距離が、前記搬送方向の上流側から前記搬送方向の下流側に向かうに連れて短くなり、前記搬送方向の下流側の端部で前記第１の寸法以下になるように形成されている、上記（２）に記載の連結包装製品の製造方法。 (3) The upper regulating means extends in the transport direction, and the distance between the lower transport belt and the upper regulating means is from the upstream side in the transport direction to the downstream side in the transport direction. The method for manufacturing a linked packaged product according to (2), wherein the method is formed so as to be shorter as it goes toward the downstream side in the transport direction so as to be equal to or smaller than the first dimension.
　吸収性物品を、下側搬送ベルトと上側規制手段との間に通過させることにより、吸収性物品の上下方向の厚さを所定の寸法以下に容易に規制することができる。 By passing the absorbent article between the lower conveyance belt and the upper regulating means, the thickness of the absorbent article in the vertical direction can be easily regulated to a predetermined dimension or less.
　（４）前記上側規制手段は、上側搬送ベルトである、上記（２）又は（３）に記載の連結包装製品の製造方法。 (4) The method for manufacturing a linked packaged product according to (2) or (3) above, wherein the upper regulating means is an upper conveying belt.
　上側搬送ベルトを用いることで、吸収性物品の厚さの規制を行うと共に、吸収性物品の搬送を補助することができ、上下方向の厚さが規制されて吸収性物品の搬送速度が落ちることを回避できる。また、上側搬送ベルトの動きにより折り畳まれた部分が捲れ上がることをさらに抑制できる。 By using the upper conveyor belt, the thickness of the absorbent article can be regulated and the conveyance of the absorbent article can be assisted, and the thickness in the vertical direction is regulated and the conveyance speed of the absorbent article is reduced. Can be avoided. Moreover, it can further suppress that the part folded by the motion of the upper side conveyance belt rolls up.
　（５）前記包装工程において、前記下側搬送ベルトの前記搬送方向の下流側に隣り合うように配設された折り曲げ部材に、前記下側搬送ベルトよりも下方側から前記連続シートを供給し、前記連続シートを前記搬送方向に搬送しつつ、前記折り曲げ部材により前記連続シートの前記横断方向の両端部を持ち上げて筒状にし、前記連続シートの前記横断方向の中央部の上方にて連続的に接合する、上記（２）乃至（４）のいずれか一項に記載の連結包装製品の製造方法。 (5) In the packaging step, the continuous sheet is supplied from a lower side than the lower conveyance belt to a bending member disposed adjacent to the downstream side in the conveyance direction of the lower conveyance belt, While conveying the continuous sheet in the conveying direction, the folding member lifts both ends in the transverse direction of the continuous sheet into a cylindrical shape, and continuously above the central portion in the transverse direction of the continuous sheet. The method for producing a linked packaged product according to any one of the above (2) to (4), which is joined.
　いわゆる横ピロー包装のうちの逆ピロー包装のプロセスを用いて連続シートの上方で接合（センターシール）を行うことで、製造プロセス中に接合（センターシール）の状態を容易に確認できると共に、折り曲げ部材（セーラー）や接合（センターシール）用の接合手段のメンテナンスを容易に行うことができる。 By using the reverse pillow packaging process of so-called horizontal pillow packaging, joining (center seal) is performed above the continuous sheet, so that the state of joining (center seal) can be easily confirmed during the manufacturing process, and the bent member (Sailor) and joining (center seal) joining means can be easily maintained.
　（６）吸収性物品製造装置により、前記吸収性物品を製造する工程と、前記吸収性物品製造装置に直接的に接続された搬送装置により、製造後の前記吸収性物品を、前記折り畳み工程の折り畳み装置へ順次搬送する搬送工程と、を更に備え、前記吸収性物品製造装置で前記吸収性物品を製造するときの単位時間当たりの製造個数と前記折り畳み装置へ前記吸収性物品を搬送するときの単位時間当たりの搬送個数とが同数である、上記（１）乃至（５）のいずれか一項に記載の連結包装製品の製造方法。 (6) The step of manufacturing the absorbent article by the absorbent article manufacturing apparatus and the folding article after the manufacture by the conveying device directly connected to the absorbent article manufacturing apparatus. A conveying step of sequentially conveying the folding article to the folding device, and the production number per unit time when the absorbent article is produced by the absorbent article producing device and when the absorbent article is conveyed to the folding device. The method for producing a linked packaged product according to any one of the above (1) to (5), wherein the number of conveyances per unit time is the same.
　製造された吸収性物品を直ちに搬送し、包装等できるので、連結包装製品の製造効率を高めることができる。 Since the manufactured absorbent article can be immediately transported and packaged, the production efficiency of linked packaged products can be increased.
　（７）前記吸収性物品は、所定方向に沿って延びる弾性体を含み、前記所定方向が前記搬送方向に沿うように搬送され、前記折り畳み工程において、前記吸収性物品のうち、前記弾性体を含む領域に前記横断方向に沿って前記折り目を形成するように前記吸収性物品を折り畳む、上記（１）乃至（６）のいずれか一項に記載の連結包装製品の製造方法。 (7) The absorbent article includes an elastic body extending along a predetermined direction, and is conveyed so that the predetermined direction is along the conveyance direction. In the folding step, the elastic body is included in the absorbent article. The method for producing a linked packaged product according to any one of (1) to (6) above, wherein the absorbent article is folded so as to form the fold along the transverse direction in a region to be included.
　搬送方向に延びる弾性体を含む領域で折り目を形成するように吸収性物品を折り畳む方が、その弾性体を含まない領域で折り目を形成するように吸収性物品を折り畳むよりも、弾性体の弾性力により、折り畳んだときの厚さが厚くなる。そして、規制工程で厚さが規制され、包装工程で筒状の連続シートに内包されると、弾性体の弾性力により、吸収性物品が筒状の連続シートをその内側からより押し拡げてより突っ張った状態にする。それにより吸収性物品を筒状の連続シート内の所定の位置により確実に位置決めできる。 It is more elastic to fold an absorbent article to form a crease in a region including the elastic body extending in the conveying direction than to fold the absorbent article to form a fold in a region not including the elastic body. The thickness when folded is increased by force. And when the thickness is regulated in the regulation process and encased in the cylindrical continuous sheet in the packaging process, the absorbent article pushes and expands the cylindrical continuous sheet from the inside by the elastic force of the elastic body. Make it stretched. Thereby, an absorbent article can be reliably positioned by the predetermined position in a cylindrical continuous sheet.
　（８）前記折り畳み工程において、前記吸収性物品の吸収体における前記横断方向の幅が最も狭い箇所以外の箇所で、前記横断方向に沿って折り目が形成されるように折り畳む、上記（１）乃至（７）のいずれか一項に記載の連結包装製品の製造方法。 (8) In the folding step, the absorbent article of the absorbent article is folded so that a crease is formed along the transverse direction at a place other than the narrowest part in the transverse direction. (7) The manufacturing method of the connection packaging product as described in any one of (7).
　吸収体における横断方向の幅が最も狭い箇所以外の箇所で折り目を形成するように吸収性物品を折り畳んだ方が、その幅が最も狭い箇所で折り目を形成するように吸収性物品を折り畳むよりも、吸収体の弾力により、折り畳んだときの厚さが厚くなる。そして、規制工程で厚さが規制され、包装工程で筒状の連続シートに内包されると、吸収体の弾力により、吸収性物品が筒状の連続シートをその内側からより押し拡げてより突っ張った状態にする。それにより吸収性物品を筒状の連続シート内の所定の位置により確実に位置決めできる。 The case where the absorbent article is folded so that a crease is formed at a place other than the place where the width in the transverse direction of the absorbent body is the narrowest than the case where the absorbent article is folded so that a crease is formed at a place where the width is the narrowest. The thickness when folded is increased by the elasticity of the absorber. Then, when the thickness is regulated in the regulation process and is encased in the cylindrical continuous sheet in the packaging process, the absorbent article pushes the cylindrical continuous sheet from its inner side and stretches more by the elasticity of the absorber. To the state. Thereby, an absorbent article can be reliably positioned by the predetermined position in a cylindrical continuous sheet.
　（９）前記吸収性物品の吸収体には長手方向に沿う坪量の低い低坪量部が形成されており、前記折り畳み工程において、前記折り目が前記低坪量部を横断するように折り畳む、上記（１）乃至（８）のいずれか一項に記載の連結包装製品の製造方法。 (9) A low basis weight portion having a low basis weight along the longitudinal direction is formed in the absorbent body of the absorbent article, and in the folding step, the fold is folded so as to cross the low basis weight portion. The method for producing a linked packaged product according to any one of (1) to (8) above.
　吸収体上の低坪量部を横断するように吸収性物品を折り畳む方が、その低坪量部を横断しないように吸収性物品を折り畳むよりも、折り目が低坪量部に遮断されて、折り畳まれた部分が開き易くなり、折り畳んだときの厚さが厚くなる。そして、規制工程で厚さが規制され、包装工程で筒状の連続シートに内包されると、折り畳まれた部分の開き易さにより、吸収性物品が筒状の連続シートをその内側からより押し拡げてより突っ張った状態にする。それにより吸収性物品を筒状の連続シート内の所定の位置により確実に位置決めできる。 Folding the absorbent article so as to cross the low basis weight part on the absorbent body is blocked by the low basis weight part rather than folding the absorbent article so as not to cross the low basis weight part, The folded part is easy to open, and the thickness when folded is increased. Then, when the thickness is regulated in the regulation process and included in the cylindrical continuous sheet in the packaging process, the absorbent article pushes the cylindrical continuous sheet from the inside due to the ease of opening the folded portion. Expand and make it more stretched. Thereby, an absorbent article can be reliably positioned by the predetermined position in a cylindrical continuous sheet.
　（１０）前記吸収性物品は、着用者の胴回りを覆う胴回り部と、吸収体を含む股部と、を備えるパンツ型おむつであり、前記折り畳み工程において、前記股部に折り目が形成されることにより前記股部の少なくとも一部が前記上下方向の上側に位置し、前記胴回り部が前記上下方向の下側に位置するように前記吸収性物品を折り畳む、上記（１）乃至（９）のいずれか一項に記載の連結包装製品の製造方法。 (10) The absorbent article is a pants-type diaper including a waistline portion covering a waistline of a wearer and a crotch portion including an absorber, and a fold is formed in the crotch portion in the folding step. Any one of (1) to (9) above, wherein the absorbent article is folded so that at least a part of the crotch portion is positioned above the vertical direction and the waistline portion is positioned below the vertical direction. A method for producing a linked packaged product according to claim 1.
　平面視での面積の広い胴回り部が下側に位置するように吸収性物品を折り畳むことで、搬送用のベルトとの接地面積が広くなり、安定的に吸収性物品を搬送することができる。特に規制工程では、上側規制手段により吸収性物品の厚さが規制されるため、搬送に影響が出るおそれがあるが、下側搬送ベルトとの接地面積が広くなり、規制の影響をほとんど受けずに安定的に吸収性物品を搬送することができる。 Folding the absorbent article so that the waistline portion with a large area in plan view is located on the lower side increases the ground contact area with the belt for conveyance, and the absorbent article can be stably conveyed. In particular, in the regulation process, the thickness of the absorbent article is regulated by the upper regulation means, which may affect the conveyance, but the contact area with the lower conveyance belt becomes wide and is hardly affected by the regulation. The absorbent article can be transported stably.
　（１１）前記吸収性物品は、着用者の胴回りを覆う胴回り部と、吸収体を含む股部と、を備えるパンツ型おむつであり、前記胴回り部は、腹側及び背側の少なくとも一方の両側面に伸縮部を有し、前記伸縮部は、前記伸縮部の肌当接面側及び非肌当接面側にそれぞれ配置された肌側シート及び非肌側シートと、それら両シート間に胴回り方向に配設された弾性部材とを有し、前記肌側シート及び前記非肌側シートが胴回り方向に延在する横長接合部により接合されており、前記横長接合部は胴回り方向に間欠的に形成されており、前記肌側シート及び前記非肌側シートが胴回り方向と交差する方向に延在する縦長接合部により接合されており、前記縦長接合部は胴回り方向に間欠的に形成されており、前記横長接合部及び前記縦長接合部は前記伸縮部に混在しており、前記折り畳み工程において、前記折り目が前記胴回り部を横断するように折り畳む、上記（１）乃至（９）のいずれか一項に記載の連結包装製品の製造方法。 (11) The absorbent article is a pants-type diaper that includes a waistline portion that covers a waistline of a wearer and a crotch portion that includes an absorber, and the waistline portion is at least one side of the abdomen and the back side. The elastic part has a stretchable part on the surface, and the stretchable part is disposed on the skin contact surface side and the non-skin contact surface side of the stretchable part, and the waistline between the two sheets.

　胴回り部を横断するように吸収性物品を折り畳む方が、その胴回り部を横断しないように吸収性物品を折り畳むよりも、胴回り部（伸縮部）の弾力により、折り畳んだときの厚さが厚くなる。そして、規制工程で厚さが規制され、包装工程で筒状の連続シートに内包されると、胴回り部（伸縮部）の弾力により、吸収性物品が筒状の連続シートをその内側からより押し拡げてより突っ張った状態にする。それにより吸収性物品を筒状の連続シート内の所定の位置により確実に位置決めできる。 Folding the absorbent article so as to cross the girth part increases the thickness when folded due to the elasticity of the girth part (expandable part) rather than folding the absorbent article so as not to cross the girth part. . Then, when the thickness is regulated in the regulation process and encased in the cylindrical continuous sheet in the packaging process, the absorbent article pushes the cylindrical continuous sheet from the inside by the elasticity of the waist part (expandable part). Expand and make it more stretched. Thereby, an absorbent article can be reliably positioned by the predetermined position in a cylindrical continuous sheet.
　本発明により、連結包装製品の製造において、搬送中の吸収性物品の厚みのばらつきの影響を抑え、筒状の連続シート内の所定の位置に吸収性物品を位置決めが可能となる。 According to the present invention, in the manufacture of linked packaged products, the influence of variation in the thickness of the absorbent article being conveyed can be suppressed, and the absorbent article can be positioned at a predetermined position in the cylindrical continuous sheet.

　図２は、連結包装製品１の製造装置１０の構成の一例を示している。図２を参照すると、連結包装製品製造装置１０は、吸収性物品製造装置２０と、折り畳みユニット１０Ａと、規制ユニット１０Ｂと、包装ユニット１０Ｃと、接合ユニット１０Ｄと、切断ユニット１０Ｅとを具備している。これらの吸収性物品製造装置２０及び各ユニット１０Ａ～１０Ｅはインライン配置になっている。 FIG. 2 shows an example of the configuration of the manufacturing apparatus 10 for the linked packaged product 1. Referring to FIG. 2, the linked packaged product manufacturing apparatus 10 includes an absorbent article manufacturing apparatus 20, a folding unit 10A, a regulation unit 10B, a packaging unit 10C, a joining unit 10D, and a cutting unit 10E. Yes. The absorbent article manufacturing apparatus 20 and the units 10A to 10E are arranged in-line.
　ただし、連結包装製品製造装置１０は、吸収性物品３等の搬送に関して、搬送方向（ＭＤ方向）、搬送方向に直交し搬送面に沿った横断方向（ＣＤ方向）及び搬送方向と横断方向とに直交する上下方向（ＴＤ方向）を有するものとする。また、「搬送方向の上流側」、「搬送方向の下流側」を単に「上流側」、「下流側」とも称し、「上下方向の上側」、「上下方向の下側」を単に「上側」、「下側」とも称する。また、吸収性物品３は長手方向（Ｌ）、長手方向に直交する幅方向（Ｗ）及び長手方向と幅方向とに直交する厚さ方向（Ｈ）を有するものとする。そして、吸収性物品３の搬送中では、搬送方向、横断方向及び上下方向は、長手方向、幅方向及び厚さ方向と重なるので、吸収性物品３の搬送中については長手方向、幅方向及び厚さ方向として搬送方向、横断方向及び上下方向も用いることとする。 However, the connected packaged product manufacturing apparatus 10 is related to the conveyance of the absorbent article 3 and the like in the conveyance direction (MD direction), the transverse direction orthogonal to the conveyance direction (CD direction) and the conveyance direction and the transverse direction. It shall have the up-and-down direction (TD direction) which intersects perpendicularly. In addition, “upstream in the transport direction” and “downstream in the transport direction” are also simply referred to as “upstream” and “downstream”, and “upward in the vertical direction” and “lower in the vertical direction” are simply “upper”. , Also referred to as “lower”. Moreover, the absorbent article 3 shall have a longitudinal direction (L), the width direction (W) orthogonal to a longitudinal direction, and the thickness direction (H) orthogonal to a longitudinal direction and a width direction. And while the absorbent article 3 is being transported, the transport direction, the transverse direction, and the vertical direction overlap the longitudinal direction, the width direction, and the thickness direction. The transport direction, the transverse direction, and the vertical direction are also used as the vertical direction.
　吸収性物品製造装置２０は、吸収性物品３を連続的に製造する。製造された吸収性物品３は、吸収性物品製造装置２０に直接的に接続された搬送ベルト２１により折り畳みユニット１０Ａに順次搬送される。 The absorbent article manufacturing apparatus 20 continuously manufactures the absorbent article 3. The manufactured absorbent article 3 is sequentially conveyed to the folding unit 10 </ b> A by the conveyor belt 21 directly connected to the absorbent article manufacturing apparatus 20.
　折り畳みユニット１０Ａは、一方向に並んで搬送されてくる吸収性物品３を搬送方向に順次搬送しながら、折り畳まれた部分が上下方向に重なるように吸収性物品３を一回以上折り畳む。本実施の形態では一回折り畳んで二つ折りの吸収性物品３を形成する。二つ折りの吸収性物品３は、搬送ベルト２５により規制ユニット１０Ｂに順次搬送される。 The folding unit 10A folds the absorbent article 3 one or more times so that the folded parts overlap in the vertical direction while sequentially transporting the absorbent articles 3 conveyed side by side in one direction in the transport direction. In the present embodiment, the absorbent article 3 is folded twice to form a bi-fold absorbent article 3. The bi-fold absorbent article 3 is sequentially transported to the regulation unit 10B by the transport belt 25.
　規制ユニット１０Ｂは、一方向に並んで搬送されてくる折り畳まれた吸収性物品３を搬送方向に順次搬送しながら、吸収性物品３の上下方向の厚さを第１の寸法以下にする規制を行う。規制後の吸収性物品３は、包装ユニット１０Ｃに順次搬送される。 The regulation unit 10B regulates the thickness of the absorbent article 3 in the vertical direction to be equal to or less than the first dimension while sequentially conveying the folded absorbent article 3 that is conveyed side by side in one direction in the conveyance direction. Do. The regulated absorbent article 3 is sequentially conveyed to the packaging unit 10C.
　包装ユニット１０Ｃは、搬送方向に搬送されつつ連続的に筒状に形成される連続シート４ｂの内側に、規制後の吸収性物品３を順次供給し、縦シール部分６（図１）を形成して吸収性物品３を包装する。このとき、筒状に形成される連続シート４ｂにおける上下方向の内側の寸法が第１の寸法である。吸収性物品３を内包する筒状の連続シート４ｂは、接合ユニット１０Ｄに順次搬送される。 The packaging unit 10C sequentially supplies the regulated absorbent articles 3 inside the continuous sheet 4b that is continuously formed in a cylindrical shape while being conveyed in the conveying direction, thereby forming the vertical seal portion 6 (FIG. 1). Then, the absorbent article 3 is packaged. At this time, the dimension inside the vertical direction in the continuous sheet 4b formed in a cylindrical shape is the first dimension. The cylindrical continuous sheet 4b containing the absorbent article 3 is sequentially conveyed to the joining unit 10D.
　接合ユニット１０Ｄは、吸収性物品３を内包した筒状の連続シート４ｂを搬送方向に搬送しながら、筒状の連続シート４ｂにおける互いに隣り合う吸収性物品３同士の間の部分で筒内面の対向する連続シート同士を接合して、横シール部分５（図１）を形成する。更に、横シール部分５に弱め線７（図１）を形成する。それにより、吸収性物品３及び包装袋４により構成される包装品２が形成されると共に、複数の包装品２が一列に連結されている包装品連結体８が形成される。包装品連結体８は、切断ユニット１０Ｅに搬送される。 While joining unit 10D conveys the cylindrical continuous sheet 4b which included the absorbent article 3 in a conveyance direction, it opposes a cylinder inner surface in the part between mutually adjacent absorbent articles 3 in the cylindrical continuous sheet 4b. The continuous sheets to be joined are joined together to form the lateral seal portion 5 (FIG. 1). Further, a weakening line 7 (FIG. 1) is formed in the lateral seal portion 5. Thereby, while the packaged goods 2 comprised by the absorbent article 3 and the packaging bag 4 are formed, the packaged goods coupling body 8 by which the some packaged goods 2 are connected with 1 row is formed. The packaged article assembly 8 is conveyed to the cutting unit 10E.
　切断ユニット１０Ｅは、形成された包装品連結体８において、予め設定された個数ごとに包装品連結体８を弱め線７で切断して、分割する。本実施の形態では、包装品２を１０個ずつに分割する。それにより、予め設定された個数の包装品２が一方向に連結されてなる連結包装製品１が形成される。連結包装製品１は、段ボール箱のような梱包箱に梱包される。したがって、製造された吸収性物品３を直ちに搬送し、包装等できるので、連結包装製品１の製造効率を高めることができる。 The cutting unit 10E cuts and divides the package connection body 8 by the weakening line 7 for each preset number in the formed package connection body 8. In the present embodiment, the packaged product 2 is divided into ten pieces. Thereby, a linked packaged product 1 is formed in which a predetermined number of packaged products 2 are linked in one direction. The linked packaged product 1 is packed in a packing box such as a cardboard box. Therefore, since the manufactured absorbent article 3 can be immediately conveyed and packaged, the manufacturing efficiency of the linked packaged product 1 can be increased.
　以下、折り畳みユニット１０Ａ、規制ユニット１０Ｂ、包装ユニット１０Ｃ、接合ユニット１０Ｄ及び切断ユニット１０Ｅの構成の一例について説明する。 Hereinafter, an example of the configuration of the folding unit 10A, the regulation unit 10B, the packaging unit 10C, the joining unit 10D, and the cutting unit 10E will be described.
　図２に示すように、折り畳みユニット１０Ａは、搬送ベルト２１、２２、２３を備えている。三角形状に架張された搬送ベルト２２の一つのベルト面に搬送ベルト２１が対面配置され、搬送ベルト２２の別の一つのベルト面に搬送ベルト２３が対面配置されている。搬送ベルト２１と搬送ベルト２２との間に形成される搬送路は折り畳まれていない吸収性物品３を把持して、搬送方向に搬送可能である。搬送ベルト２２と搬送ベルト２３との間に形成される搬送路は折り畳まれた吸収性物品３を把持して、搬送方向に搬送可能である。搬送ベルト２２側の搬送路は、搬送ベルト２１側の搬送路に所定角度（例示：９０度）で交差している。折り畳みユニット１０Ａは、その交差点の近傍に折り板２４を更に備えている。折り板２４は、搬送ベルト２１側の搬送路に上記の所定角度で交差し、搬送ベルト２３側の搬送路に平行となるようにその交差点に出入りする。したがって、折り板２４の交差点への出入りのタイミングと、搬送ベルト２１側の搬送路での吸収性物品３の搬送のタイミングとを合わせることで、搬送ベルト２１側の搬送路で搬送される吸収性物品３を、折り板２４で搬送ベルト２３側の搬送路に折り込み、それにより吸収性物品３の折り畳みを可能としている。 As shown in FIG. 2, the folding unit 10 </ b> A includes transport belts 21, 22, and 23. The conveyor belt 21 is disposed facing one belt surface of the conveyor belt 22 stretched in a triangular shape, and the conveyor belt 23 is disposed facing the other belt surface of the conveyor belt 22. The conveyance path formed between the conveyance belt 21 and the conveyance belt 22 can grip the absorbent article 3 that is not folded and can convey the absorbent article 3 in the conveyance direction. The conveyance path formed between the conveyance belt 22 and the conveyance belt 23 can hold the folded absorbent article 3 and convey it in the conveyance direction. The conveyance path on the conveyance belt 22 side intersects the conveyance path on the conveyance belt 21 side at a predetermined angle (example: 90 degrees). The folding unit 10A further includes a folding plate 24 in the vicinity of the intersection. The folding plate 24 crosses the conveyance path on the conveyance belt 21 side at the predetermined angle and enters and exits the intersection so as to be parallel to the conveyance path on the conveyance belt 23 side. Therefore, the absorbency conveyed by the conveyance path by the side of the conveyance belt 21 is match | combined with the timing of entrance / exit to the intersection of the folding plate 24, and the timing of conveyance of the absorbent article 3 by the conveyance path by the side of the conveyance belt 21. The article 3 is folded by the folding plate 24 into the conveyance path on the side of the conveyance belt 23, thereby enabling the absorbent article 3 to be folded.
　規制ユニット１０Ｂは、下側搬送ベルト３１と、上側規制手段３２とを備えている。本実施の形態では、上側規制手段３２は搬送方向に延在する上側搬送ベルトである。図３は規制ユニット１０Ｂの側面図及び頂面図を示している。図３に示すように、下側搬送ベルト３１と上側規制手段３２とは対面配置されており、下側搬送ベルト３１と上側規制手段３２との間に、折り畳まれた吸収性物品３を搬送方向に搬送する搬送路（空間３３ｓ）が形成されている。下側搬送ベルト３１と上側規制手段３２とは横断方向の中心の位置が互いに重なるように配置され、下側搬送ベルト３１の幅が上側規制手段３２の幅より大きく形成されている。規制ユニット１０Ｂは、吸収性物品３が搬送される空間３３ｓの横断方向の両側に、互いに対向する一対の規制部材３３を更に備えている。本実施の形態では、一対の規制部材３３は、金属や樹脂などの平板部材で形成されたガイド板であり、下側搬送ベルト３１の搬送面から上下方向に略垂直に立設されている。 The regulation unit 10B includes a lower conveyance belt 31 and an upper regulation means 32. In the present embodiment, the upper regulating means 32 is an upper conveyance belt extending in the conveyance direction. FIG. 3 shows a side view and a top view of the regulating unit 10B. As shown in FIG. 3, the lower conveyance belt 31 and the upper restriction means 32 are disposed so as to face each other, and the absorbent article 3 folded between the lower conveyance belt 31 and the upper restriction means 32 is conveyed in the conveyance direction. A transport path (space 33s) for transporting to the surface is formed. The lower conveying belt 31 and the upper restricting means 32 are arranged so that the center positions in the transverse direction overlap each other, and the width of the lower conveying belt 31 is formed larger than the width of the upper restricting means 32. The restriction unit 10B further includes a pair of restriction members 33 facing each other on both sides in the transverse direction of the space 33s in which the absorbent article 3 is conveyed. In the present embodiment, the pair of regulating members 33 are guide plates formed of a flat plate member such as metal or resin, and are erected substantially vertically from the conveyance surface of the lower conveyance belt 31 in the vertical direction.
　図４（Ａ）及び図４（Ｂ）は下側搬送ベルト３１、上側規制手段３２及び一対の規制部材３３を搬送方向の上流側及び下流側から見た図を示している。一対の規制部材３３及び搬送ロール３１ａ、３２ａで囲まれた領域が吸収性物品３の搬送路（空間３３ｓ）の入口であり、一対の規制部材３３及び搬送ロール３１ｂ、３２ｂで囲まれた領域が吸収性物品３の搬送路（空間３３ｓ）の出口となる。 4 (A) and 4 (B) show views of the lower conveying belt 31, the upper regulating means 32, and the pair of regulating members 33 as seen from the upstream side and the downstream side in the conveying direction. A region surrounded by the pair of regulating members 33 and the conveyance rolls 31a and 32a is an entrance of the conveyance path (space 33s) of the absorbent article 3, and a region surrounded by the pair of regulating members 33 and the conveyance rolls 31b and 32b. It becomes an exit of the conveyance path (space 33s) of the absorbent article 3.
　下側搬送ベルト３１と上側規制手段３２との間における上下方向の距離、すなわち内側上下距離は、搬送方向の上流側の端部３３ａ（図４（Ａ））から下流側の端部３３ｂ（図４（Ｂ））に向かうに連れて短くなっている。すなわち、その内側上下距離は、上流側の端部３３ａにおいてｄｓ２であるが、下流側の端部３３ｂにおいてｄｅ２（＜ｄｓ２）である。上流側の端部３３ａでの内側上下距離ｄｓ２は、少なくとも規制工程前の吸収性物品３の上下方向の厚さよりも予測される厚さのばらつきの程度大きい値に設定される。下流側の端部３３ｂでの内側上下距離ｄｅ２は、後述される第１の寸法Ｄ０２以下に設定される。したがって、下側搬送ベルト３１と上側規制手段３２との間に吸収性物品３を通すことによって、上下方向の吸収性物品３の厚さを第１の寸法Ｄ０２以下に規制可能である。 The vertical distance between the lower conveying belt 31 and the upper regulating means 32, that is, the inner vertical distance is the downstream end 33b (FIG. 4A) from the upstream end 33a (FIG. 4A) in the conveying direction. 4 (B)), it is getting shorter. That is, the inner vertical distance is ds2 at the upstream end 33a, but de2 (<ds2) at the downstream end 33b. The inner vertical distance ds2 at the upstream end portion 33a is set to a value that is at least as large as the expected thickness variation than the thickness in the vertical direction of the absorbent article 3 before the regulation step. The inner vertical distance de2 at the downstream end 33b is set to a first dimension D02 or less which will be described later. Therefore, by passing the absorbent article 3 between the lower conveyance belt 31 and the upper regulating means 32, the thickness of the absorbent article 3 in the vertical direction can be regulated to the first dimension D02 or less.
　一対の規制部材３３における横断方向の互いの内側の距離、すなわち内側横断距離は、上流側の端部３３ａ（図４（Ａ））から下流側の端部３３ｂ（図４（Ｂ））に向かうに連れて短くなっている。すなわち、その内側横断距離は、上流側の端部３３ａにおいてｄｓ１であるが、下流側の端部３３ｂにおいてｄｅ１（＜ｄｓ１）である。上流側の端部３３ａでの内側横断距離ｄｓ１は、規制工程前の吸収性物品３の横断方向の幅よりも予測される位置ずれの程度大きい値に設定される。下流側の端部３３ｂでの内側横断距離ｄｅ１は、後述される第２の寸法Ｄ０１以下に設定される。したがって、一対の規制部材３３の間に吸収性物品３を通すことによって、横断方向の吸収性物品３の幅を第２の寸法Ｄ０１以下に規制可能である。 The distance between the pair of regulating members 33 in the transverse direction, that is, the inner transverse distance, is from the upstream end 33a (FIG. 4A) to the downstream end 33b (FIG. 4B). Is getting shorter. That is, the inner transverse distance is ds1 at the upstream end portion 33a, but is de1 (<ds1) at the downstream end portion 33b. The inner transverse distance ds1 at the upstream end portion 33a is set to a value that is larger than the predicted positional deviation than the transverse width of the absorbent article 3 before the regulation step. The inner transverse distance de1 at the downstream end 33b is set to be equal to or smaller than a second dimension D01 described later. Therefore, by passing the absorbent article 3 between the pair of regulating members 33, the width of the absorbent article 3 in the transverse direction can be regulated to the second dimension D01 or less.
　このとき、上流側の端部３３ａにおいて内側上下距離ｄｓ２は、吸収性物品３が一対の規制部材３３の間に入った後しばらくしてから上側規制手段３２が吸収性物品３の厚さを規制するように設定されることが好ましい。その場合、規制工程では、まず規制部材３３による吸収性物品３の横断方向の幅の規制を開始して、それにより吸収性物品３を横断方向の所定の位置にずらす（例示：センタリングする）ことができる。更に、その後に下側搬送ベルト３１及び上側規制手段３２による吸収性物品３の上下方向の厚さの規制を開始して、吸収性物品３を横断方向の所定の位置からずれないように上下方向から押さえながら、吸収性物品３の横断方向の幅及び上下方向の厚さの規制を行うことができる。それにより、吸収性物品３の上下方向の位置合わせとその保持とを的確に実行でき、上下方向の位置決めと横断方向の幅及び上下方向の厚さの規制とを同時により適切に行うことができる。 At this time, the inner upper and lower distance ds2 at the upstream end portion 33a is a short time after the absorbent article 3 enters between the pair of regulating members 33, and the upper regulating means 32 regulates the thickness of the absorbent article 3. It is preferable to set so as to. In that case, in the regulation process, first, regulation of the width in the transverse direction of the absorbent article 3 by the regulation member 33 is started, and thereby the absorbent article 3 is shifted to a predetermined position in the transverse direction (example: centering). Can do. Further, the regulation of the thickness in the vertical direction of the absorbent article 3 by the lower conveying belt 31 and the upper regulating means 32 is started thereafter, so that the absorbent article 3 does not deviate from a predetermined position in the transverse direction. The width in the transverse direction and the thickness in the up-down direction of the absorbent article 3 can be regulated while pressing from above. Thereby, the vertical alignment and holding of the absorbent article 3 can be accurately executed, and the vertical positioning and the transverse width and vertical thickness regulation can be performed more appropriately at the same time. .
　また、上記の規制ユニット１０Ｂでは、内側上下距離が上流側の端部３３ａから下流側の端部３３ｂに向かうに連れて短くなるとしているが、その場合、上流側の端部３３ａと下流側の端部３３ｂとの間で単調に短くなってもよいし、その途中で部分的に一定であってもよい。同様に、内側上下距離が上流側の端部３３ａから下流側の端部３３ｂに向かうに連れて短くなるとしているが、上流側の端部３３ａと下流側の端部３３ｂとの間で単調に短くなってもよいし、その途中で部分的に一定であってもよい。 Further, in the restriction unit 10B, the inner vertical distance is shortened from the upstream end 33a toward the downstream end 33b. In this case, the upstream end 33a and the downstream end 33b are shortened. It may be monotonously shortened from the end portion 33b, or may be partially constant along the way. Similarly, the inner vertical distance decreases from the upstream end 33a toward the downstream end 33b, but monotonically between the upstream end 33a and the downstream end 33b. It may be shorter or may be partially constant along the way.
　また、上記の規制ユニット１０Ｂでは、下側搬送ベルト３１の幅が上側規制手段３２の幅より大きく形成されているが、本発明はその例に限定されるものでは無く、下側搬送ベルト３１の幅が上側規制手段３２の幅以下であってもよい。 Further, in the restriction unit 10B, the width of the lower conveyance belt 31 is formed larger than the width of the upper restriction means 32, but the present invention is not limited to this example, and the lower conveyance belt 31 The width may be equal to or smaller than the width of the upper regulating means 32.
　また、上記の規制ユニット１０Ｂでは、規制部材３３が下側搬送ベルト３１の搬送面から略垂直に立設されているが、本発明はその例に限定されるものでは無く、例えば、規制部材３３（ガイド板）が搬送面と所定の角度（例示：６０度）を成すように斜めに立設されていてもよい。 In the restriction unit 10B, the restriction member 33 is erected substantially vertically from the conveyance surface of the lower conveyance belt 31. However, the present invention is not limited to this example. For example, the restriction member 33 is provided. The (guide plate) may be erected obliquely so as to form a predetermined angle (example: 60 degrees) with the transport surface.
　図２に示すように、包装ユニット１０Ｃは、下側搬送ベルト３１の下流側に隣り合うように配置された折り曲げ部材４３を備えている。折り曲げ部材４３は、搬送ローラ４２によりシートロール４０から巻き戻された連続シート４ａを下側搬送ベルト３１及び折り曲げ部材４３よりも鉛直下方側から連続的に供給される。折り曲げ部材４３は、供給された連続シート４ａが通過することにより、連続シート４ａの横断方向の両側端縁部を持ち上げて、連続シート４ａの横断方向の中央部の上方にて両側端縁部同士を重ねて重なり部を形成することができる。それにより折り曲げ部材４３において筒状の連続シート４ｂが形成される。 As shown in FIG. 2, the packaging unit 10 </ b> C includes a bending member 43 disposed so as to be adjacent to the downstream side of the lower conveyance belt 31. The bending member 43 is continuously supplied from the lower conveyance belt 31 and the bending member 43 from the vertically lower side with the continuous sheet 4 a rewound from the sheet roll 40 by the conveyance roller 42. The bending member 43 lifts both side edges in the transverse direction of the continuous sheet 4a when the supplied continuous sheet 4a passes, and the edge parts on both sides above the central part in the transverse direction of the continuous sheet 4a. Can be overlapped to form an overlapping portion. Thereby, the cylindrical continuous sheet 4 b is formed in the bending member 43.
　図３に示すように、折り曲げ部材４３の上流側の入口と吸収性物品３の搬送路（空間３３ｓ）の出口（図４（Ｂ））とは対向している。図５は包装ユニット１０Ｃの折り曲げ部材を上流側から見た図を示している。連続シート４ｂは、折り曲げ部材４３の内壁に沿うように筒状に形成され、その上下方向の内側の寸法が第１の寸法Ｄ０２となり、その横断方向の内側の寸法が第２の寸法Ｄ０１となる。第１の寸法Ｄ０２は規制された吸収性物品３の上下方向の厚さ以上であり、第２の寸法Ｄ０１は規制された吸収性物品３の横断方向の幅以上である。したがって、規制された吸収性物品３は筒状の連続シート４ｂの内部４ｂｓへ挿入されることができる。なお、筒状の連続シート４ｂの横断方向の両側端縁部同士は重なり、重なり部を形成しているが、この段階では接合されていない。 As shown in FIG. 3, the upstream inlet of the bending member 43 and the outlet (FIG. 4B) of the conveyance path (space 33s) of the absorbent article 3 face each other. FIG. 5 shows a view of the bending member of the packaging unit 10C as viewed from the upstream side. The continuous sheet 4b is formed in a cylindrical shape along the inner wall of the bending member 43, the inner dimension in the vertical direction is the first dimension D02, and the inner dimension in the transverse direction is the second dimension D01. . The first dimension D02 is equal to or greater than the thickness in the vertical direction of the regulated absorbent article 3, and the second dimension D01 is equal to or greater than the width in the transverse direction of the regulated absorbent article 3. Therefore, the regulated absorbent article 3 can be inserted into the inside 4bs of the cylindrical continuous sheet 4b. In addition, although both the side edge parts of the cross direction of the cylindrical continuous sheet 4b overlap and form the overlap part, it is not joined at this stage.
　図２に示すように、折り曲げ部材４３にはその上流側の端部において規制ユニット１０Ｂからの吸収性物品３が供給される。このとき、折り曲げ部材４３上では連続シート４ａが筒状に形成されて筒状の連続シート４ｂが形成されている。したがって、折り曲げ部材４３により連続的に筒状に形成される連続シート４ｂ内に吸収性物品３が供給される、ということができる。 As shown in FIG. 2, the absorbent article 3 from the regulation unit 10B is supplied to the bending member 43 at the upstream end thereof. At this time, on the bending member 43, the continuous sheet 4a is formed in a cylindrical shape, and the cylindrical continuous sheet 4b is formed. Therefore, it can be said that the absorbent article 3 is supplied into the continuous sheet 4b formed continuously in a cylindrical shape by the bending member 43.
　ここで、本実施の形態では、規制ユニット１０Ｂの上側規制手段３２の下流側の端部は、下側搬送ベルト３１の下流側の端部よりも包装ユニット１０Ｃ側へ張り出している。一方、包装ユニット１０Ｃの折り曲げ部材４３の上流側の下側の端部は、規制ユニット１０Ｂ側へ張り出している。言い換えると、上側規制手段３２の下流側の端部と折り曲げ部材４３の上流側の下側の端部とが互いにオーバーラップしている。それにより、規制ユニット１０Ｂからの吸収性物品３を包装ユニット１０Ｃの筒状の連続シート４ｂへより円滑に供給できる。 Here, in the present embodiment, the downstream end of the upper restricting means 32 of the restricting unit 10B projects from the downstream end of the lower conveying belt 31 toward the packaging unit 10C. On the other hand, the lower end on the upstream side of the bending member 43 of the packaging unit 10C protrudes toward the regulation unit 10B. In other words, the downstream end of the upper restricting means 32 and the upstream lower end of the bending member 43 overlap each other. Thereby, the absorbent article 3 from the regulation unit 10B can be supplied more smoothly to the cylindrical continuous sheet 4b of the packaging unit 10C.
　包装ユニット１０Ｃは、縦シール器４４と搬送ベルト４５とを更に備えている。縦シール器４４と搬送ベルト４５とは対面配置されており、搬送ベルト４５が吸収性物品３を内包した筒状の連続シート４ａを搬送方向に搬送しつつ、縦シール器４４が連続シート４ｂの上側に形成されている重なり部分をシールして、縦シール部分６（図１）を形成する。シール方法は加熱による熱融着が挙げられる。 The packaging unit 10 </ b> C further includes a vertical sealer 44 and a conveyance belt 45. The vertical sealer 44 and the conveyor belt 45 are arranged so as to face each other. The conveyor belt 45 conveys the cylindrical continuous sheet 4a containing the absorbent article 3 in the conveyance direction, while the vertical sealer 44 of the continuous sheet 4b. The overlapping portion formed on the upper side is sealed to form the vertical seal portion 6 (FIG. 1). Examples of the sealing method include heat fusion by heating.
　このような包装ユニット１０Ｃは、いわゆる横ピロー包装のうちの逆ピロー包装のプロセスを用いており、連続シート４ｂの縦シール部分６（センターシール）を形成する縦シール器４４は連続シート４ｂの上側に設けられている。そのため、包装ユニット１０Ｃの動作中に縦シール部分６（センターシール）の状態を容易に確認できると共に、折り曲げ部材４３（セーラー）のメンテナンスを容易に行うことができる。また、折り曲げ部材４３の内部にまで下側搬送ベルト３１を挿入しないことで、筒状の連続シート４ｂの横断方向の内側の寸法を大きくとる必要が無くなり、連続シート４ｂの使用量を削減することができる。 Such a packaging unit 10C uses a reverse pillow packaging process of so-called horizontal pillow packaging, and the vertical sealer 44 that forms the vertical seal portion 6 (center seal) of the continuous sheet 4b is located above the continuous sheet 4b. Is provided. Therefore, the state of the vertical seal portion 6 (center seal) can be easily confirmed during the operation of the packaging unit 10C, and the bending member 43 (sailor) can be easily maintained. Further, by not inserting the lower conveyance belt 31 into the bending member 43, it is not necessary to increase the dimension inside the transverse direction of the cylindrical continuous sheet 4b, and the amount of use of the continuous sheet 4b is reduced. Can do.
　接合ユニット１０Ｄは一対の搬送ベルト５１、５２と、横シール器５３とを備えている。一対の搬送ベルト５１、５２は、互いに対面配置されており、吸収性物品３を内包した筒状の連続シート４ａを搬送ベルト５１、５２の間に把持しつつ、搬送方向に横シール器５３まで搬送する。横シール器５３は互いに対面配置された一対の押圧部材５４、５５を含み、一対の押圧部材５４、５５は互いに隣り合う吸収性物品３同士の間において連続シート４ａを横断方向にシールして、横シール部分５（図１）を形成する。シール方法は加熱による熱融着が挙げられる。このとき、押圧部材５４、５５は更に、連続シート４ａの横シール部分５に弱め線７（図１）を形成する。それらにより、包装品連結体８が形成される。 The joining unit 10D includes a pair of conveyor belts 51 and 52 and a lateral sealer 53. The pair of transport belts 51 and 52 are arranged so as to face each other, and hold the cylindrical continuous sheet 4 a containing the absorbent article 3 between the transport belts 51 and 52, up to the lateral sealer 53 in the transport direction. Transport. The horizontal sealer 53 includes a pair of pressing members 54 and 55 arranged to face each other, and the pair of pressing members 54 and 55 seals the continuous sheet 4a in the transverse direction between the absorbent articles 3 adjacent to each other. A lateral seal portion 5 (FIG. 1) is formed. Examples of the sealing method include heat fusion by heating. At this time, the pressing members 54 and 55 further form a weakening line 7 (FIG. 1) in the lateral seal portion 5 of the continuous sheet 4a. Thereby, the packaged article connector 8 is formed.
　切断ユニット１０Ｅは一対の搬送ベルト６１、６２と、切断器６３とを備えている。一対の搬送ベルト６１、６２は、互いに対面配置されており、包装品連結体８を搬送ベルト６１、６２の間に把持しつつ、搬送方向に切断器６３まで搬送する。切断器６３は互いに対面配置された一対のローラ６４、６５を含み、一対のローラ６４、６５はローラ６４、６５の間に包装品連結体８を把持しつつ搬送する。そして、包装品連結体８を切断すべきときに、ローラ６４、６５による包装品連結体８の搬送速度を、搬送ベルト６１、６２による包装品連結体８の搬送速度と比較して速くすることにより、包装品連結体８を切断する。それにより、所定数の包装品２が連結された連結包装製品１が形成される。 The cutting unit 10E includes a pair of conveying belts 61 and 62 and a cutter 63. The pair of transport belts 61 and 62 are arranged so as to face each other, and transports the packaged article coupling body 8 to the cutting device 63 in the transport direction while holding the package connection body 8 between the transport belts 61 and 62. The cutting device 63 includes a pair of rollers 64 and 65 arranged to face each other. The pair of rollers 64 and 65 conveys the packaged article coupling body 8 between the rollers 64 and 65. Then, when the packaged article coupling body 8 is to be cut, the conveyance speed of the packaged article coupling body 8 by the rollers 64 and 65 is made faster than the conveyance speed of the packaged article coupling body 8 by the conveyor belts 61 and 62. Thus, the packaged article connector 8 is cut. Thereby, the linked packaged product 1 in which a predetermined number of packaged products 2 are linked is formed.
　切断ユニット１０Ｅは更に一対の搬送ベルト６６、６７を備え、一対の搬送ベルト６６、６７は互いに対面配置されており、連結包装製品１を搬送ベルト６６、６７間に把持しつつ、連結包装製品１を梱包するための梱包装置（図示せず）まで連結包装製品１を搬送する。 The cutting unit 10E further includes a pair of transport belts 66 and 67, and the pair of transport belts 66 and 67 are arranged so as to face each other, and the connected package product 1 is held between the transport belts 66 and 67 while being held. The connected packaged product 1 is transported to a packing device (not shown) for packing the.
　本実施の形態では、空間３３ｓを上下方向の上側から覆う規制手段としては、図３に示すような上側規制手段３２、すなわち上側搬送ベルトを用いているが、本発明はこの例に限定されるものでは無く、例えば図６に示すように他の規制手段３２Ｐ、すなわち金属や樹脂などの板材で形成されたガイド板を用いてもよい。ガイド板を用いる場合、その構造を簡略化することができる。また、上側搬送ベルト又はガイド板を用いると、製造や取り扱いが容易であり、コストも低く抑えられる。 In this embodiment, as the restricting means that covers the space 33s from the upper side in the vertical direction, the upper restricting means 32 as shown in FIG. 3, that is, the upper conveying belt is used, but the present invention is limited to this example. For example, as shown in FIG. 6, other restricting means 32P, that is, a guide plate formed of a plate material such as metal or resin may be used. When the guide plate is used, the structure can be simplified. Moreover, when an upper conveyance belt or a guide plate is used, manufacturing and handling are easy, and the cost can be kept low.
　また、本実施の形態では、空間３３ｓを横断方向の両側から挟む規制手段としては、図３に示す規制部材３３、すなわち金属や樹脂などの板材で構成されたガイド板を用いているが、本発明はこの例に限定されるものでは無く、例えば図６に示す他の規制部材３３Ｐ、すなわち互いに対面配置された一対の規制ベルトを用いてもよい。規制ベルトを用いる場合、規制の機能に加えて、吸収性物品３の搬送を補助することができ、規制されて吸収性物品３の搬送速度が落ちることを確実に回避できる。また、規制ベルト又はガイド板を用いると、製造や取り扱いが容易であり、コストも低く抑えられる。 Further, in the present embodiment, as the restricting means for sandwiching the space 33s from both sides in the transverse direction, the restricting member 33 shown in FIG. 3, that is, a guide plate made of a plate material such as metal or resin is used. The invention is not limited to this example. For example, another regulating member 33P shown in FIG. 6, that is, a pair of regulating belts arranged to face each other may be used. When the regulation belt is used, in addition to the regulation function, the conveyance of the absorbent article 3 can be assisted, and it is possible to reliably avoid the regulation and the conveyance speed of the absorbent article 3 from being lowered. Further, when a regulation belt or a guide plate is used, manufacturing and handling are easy, and the cost can be kept low.
　次に、本発明に係る連結包装製品の製造方法の実施の形態について説明する。本実施の形態の連結包装製品の製造方法では、製造工程と、折り畳み工程と、規制工程と、包装工程と、接合工程と、切断工程とが実行される。図２に示すように、吸収性物品３は黒矢印のように搬送され、これらの工程はそれぞれ吸収性物品製造装置２０及び各ユニット１０Ａ～１０Ｅで順次実行される。図７～図９は連結包装製品の製造方法を説明する図である。このうち、図７～図８は各製造工程での吸収性物品等の頂面及び側面を模式的に示す図（図面の上側が搬送方向の上流側、下側が下流側）であり、図９は一部の製造工程での吸収性物品等の断面を模式的に示す図である。 Next, an embodiment of a method for manufacturing a linked packaged product according to the present invention will be described. In the method for manufacturing a linked packaged product according to the present embodiment, a manufacturing process, a folding process, a regulation process, a packaging process, a joining process, and a cutting process are executed. As shown in FIG. 2, the absorbent article 3 is conveyed as indicated by a black arrow, and these steps are sequentially executed by the absorbent article manufacturing apparatus 20 and the units 10A to 10E, respectively. 7 to 9 are diagrams for explaining a method of manufacturing a linked packaged product. Among these, FIGS. 7 to 8 are diagrams schematically showing the top surface and side surfaces of the absorbent article or the like in each manufacturing process (the upper side of the drawing is the upstream side in the transport direction, and the lower side is the downstream side). These are figures which show typically the cross section of an absorptive article etc. in a part of manufacturing process.
　製造工程では、吸収性物品製造装置２０により、吸収性物品３が連続的に製造される。本実施の形態では、吸収性物品３は図７（Ａ）に示すようにパンツ型おむつであり、着用者の胴回りを覆う胴回り部３ａと、吸収体を含む股部３ｂとを備えている。股部３ｂは、吸収体の横断方向の幅が最も狭い箇所３ｇで二つ折りにされて、腹側の部分３ｂ１の端部を胴回り部３ａの腹側面２ａ１に、背側の部分３ｂ２の端部を胴回り部３ａの背側面３ａ２にそれぞれ結合されている。吸収性物品３の横断方向の幅はＷ０であり、上下方向の厚さはＨ０である。胴回り部３ａにはゴムのような弾性体３ｅが横断方向に沿って配置されている。股部３ｂの横断方向の側部にはレッグギャザー３ｃが搬送方向に沿って設けられ、レッグギャザー３ｃにはゴムのような弾性体３ｆが搬送方向に沿って配置されている。 In the manufacturing process, the absorbent article 3 is continuously manufactured by the absorbent article manufacturing apparatus 20. In this Embodiment, the absorbent article 3 is a pants-type diaper as shown to FIG. 7 (A), and is provided with the waist part 3a which covers a wearer's waist, and the crotch part 3b containing an absorber. The crotch portion 3b is folded in half at a portion 3g where the width of the absorbent body in the transverse direction is the narrowest. The end of the abdomen portion 3b1 is connected to the abdomen side surface 2a1 of the waistline portion 3a and Are respectively coupled to the back side surface 3a2 of the waistline portion 3a. The width of the absorbent article 3 in the transverse direction is W0, and the thickness in the vertical direction is H0. An elastic body 3e such as rubber is disposed along the transverse direction on the waist portion 3a. Leg gathers 3c are provided along the conveyance direction on the lateral sides of the crotch 3b, and elastic bodies 3f such as rubber are arranged along the conveyance direction on the leg gathers 3c.
　製造された吸収性物品３は、図２に示すように吸収性物品製造装置２０に直接的に接続された搬送ベルト２１により折り畳みユニット１０Ａに順次搬送される。その吸収性物品３のおむつは、搬送方向の下流側に股部３ｂが位置するように搬送される。このとき、吸収性物品製造装置２０により吸収性物品３を製造するときの処理量、すなわち単位時間当たりの製造個数と、搬送ベルト２１により吸収性物品３を搬送するときの処理量、すなわち単位時間当たりの搬送個数とは同じである。搬送ベルト２１の処理量は各ユニット１０Ａ～１０Ｅの処理量と同じであることから、吸収性物品製造装置２０と各ユニット１０Ａ～１０Ｅとは製造及び包装を連続的に行っているということができる。 The manufactured absorbent article 3 is sequentially transported to the folding unit 10A by a transport belt 21 directly connected to the absorbent article manufacturing apparatus 20 as shown in FIG. The diaper of the absorbent article 3 is conveyed so that the crotch portion 3b is located on the downstream side in the conveying direction. At this time, the processing amount when the absorbent article 3 is manufactured by the absorbent article manufacturing apparatus 20, that is, the number of units manufactured per unit time, and the processing amount when the absorbent article 3 is transported by the transport belt 21, that is, unit time. The number of hits is the same. Since the processing amount of the conveyor belt 21 is the same as the processing amount of each unit 10A to 10E, it can be said that the absorbent article manufacturing apparatus 20 and each unit 10A to 10E are continuously manufactured and packaged. .
　折り畳み工程では、折り畳みユニット１０Ａにより、製造された吸収性物品３が折り畳まれる。すなわち、折り畳みユニット１０Ａでは、吸収性物品３が搬送ベルト２１、２２に挟まれて連続的に搬送され、吸収性物品３の搬送方向の中央部が搬送ロール２２ａ、２３ａの間の位置に来たタイミングで、吸収性物品３の厚さ方向にその中央部が折り板２４で突かれる。それにより、吸収性物品３が二つに折り畳まれながら搬送ロール２２ａ、２３ａ間に押し込まれて、一対の搬送ベルト２２、２３の間に挟み込まれる。二つに折り畳まれた吸収性物品３は一対の搬送ベルト２２、２３及び搬送ベルト２５により規制ユニット１０Ｂに順次搬送される。 In the folding step, the manufactured absorbent article 3 is folded by the folding unit 10A. That is, in the folding unit 10A, the absorbent article 3 is continuously conveyed while being sandwiched between the conveyor belts 21 and 22, and the central portion of the absorbent article 3 in the conveyance direction has come to a position between the conveyance rolls 22a and 23a. At the timing, the central portion of the absorbent article 3 is projected by the folded plate 24 in the thickness direction. Thereby, the absorbent article 3 is pushed in between the transport rolls 22a and 23a while being folded in two, and is sandwiched between the pair of transport belts 22 and 23. The absorbent article 3 folded in two is sequentially transported to the regulation unit 10B by the pair of transport belts 22, 23 and the transport belt 25.
　図７（Ａ）に示す吸収性物品３のおむつは、折り板２４が折り目ＦＬに当接することにより図７（Ｂ）及び図９（Ａ）に示すように折り畳まれる。この図の例では、折り目ＦＬは横断方向に沿って、股部３ｂにおける吸収体の横断方向の幅が最も狭い箇所３ｇ以外の箇所を通り、レッグギャザー３ｃの領域を通り、胴回り部３ａの搬送方向の下流側の端部の近傍を通るように形成される。このとき、股部３ｂに折り目ＦＬが形成されることにより、股部３ｂの少なくとも一部が上下方向の上側に位置し、胴回り部３ａが上下方向の下側に位置して搬送ベルト２５に接するように吸収性物品３が折り畳まれる。吸収性物品３の横断方向の幅はＷ１であり、折り畳み工程の前と概ね同じである。吸収性物品３の上下方向の厚さはＨ１となり、折り畳み工程の前の厚さＨ０より厚くなる。ただし、折り畳み工程での折り目ＦＬの微妙なずれにより、折り畳んだ後の吸収性物品３の上下方向の厚さＨ１にはばらつきが発生している場合があり得る。その後、吸収性物品３における下流側に折り目ＦＬが位置するようにして、吸収性物品３は搬送ベルト２５により搬送される。 7 (A), the diaper of the absorbent article 3 is folded as shown in FIG. 7 (B) and FIG. 9 (A) when the folding plate 24 contacts the crease FL. In the example of this figure, the crease FL passes along the transverse direction through a part other than the part 3g where the width of the absorbent body in the crotch part 3b is the smallest in the transverse direction, passes through the region of the leg gather 3c, and conveys the waist part 3a It is formed so as to pass in the vicinity of the end portion on the downstream side in the direction. At this time, by forming the crease FL in the crotch portion 3b, at least a part of the crotch portion 3b is positioned on the upper side in the vertical direction, and the waist portion 3a is positioned on the lower side in the vertical direction so as to contact the conveyance belt 25. Thus, the absorbent article 3 is folded. The width of the absorbent article 3 in the transverse direction is W1, which is substantially the same as before the folding step. The thickness of the absorbent article 3 in the vertical direction is H1, which is greater than the thickness H0 before the folding step. However, there may be a variation in the thickness H1 in the vertical direction of the absorbent article 3 after folding due to a slight shift of the crease FL in the folding step. Thereafter, the absorbent article 3 is transported by the transport belt 25 so that the crease FL is positioned on the downstream side of the absorbent article 3.
　ここで、本実施の形態では、折り畳まれた吸収性物品３における横断方向の幅が最も広い箇所が、吸収性物品３における搬送方向の前側（下流側）の半分内に位置するようにして吸収性物品３が搬送方向に搬送される。 Here, in the present embodiment, absorption is performed such that the portion having the widest width in the transverse direction in the folded absorbent article 3 is located in the front half (downstream side) of the absorbent article 3 in the transport direction. The property article 3 is conveyed in the conveyance direction.
　規制工程では、規制ユニット１０Ｂにより、折り畳まれた吸収性物品３の大きさが規制される。すなわち、規制ユニット１０Ｂでは、搬送ベルト２５により搬送されてきた（折り畳まれた）吸収性物品３が下側搬送ベルト３１により搬送方向に搬送される。このとき、一対の規制部材３３において、上流側の端部３３ａ（図４（Ａ））の内側横断距離ｄｓ１は、規制工程前の吸収性物品３の横断方向の幅Ｗ１よりも長く且つ吸収性物品３の横断方向の位置ずれを吸収できる程度に長くなるように設定されている。したがって、吸収性物品３は横断方向については位置ずれの有無に拘らず空間３３ｓに容易に挿入される。そして、吸収性物品３が空間３３ｓ内を上流側から下流側へ搬送されるとき、内側横断距離が上流側から下流側に向かうに連れて短くなるので、吸収性物品３の横断方向の幅が規制部材３３で規制されて小さくなる。その結果、規制部材３３の下流側（図４（Ｂ））の端部３３ｂにおいて、吸収性物品３の横断方向の幅が、規制部材３３の下流側の端部３３ｂの内側横断距離ｄｅ１と同じになり、規制部材３３から搬出される。このように吸収性物品３は、一対の規制部材３３の間に通されることにより、横断方向の幅をｄｅ１に規制される。言い換えると、吸収性物品３のおむつは、図７（Ｃ）に示すように横断方向の幅がＷ２≒ｄｅｌとなり、規制工程の前の横断方向の幅Ｗ１よりも小さくなる。それにより、吸収性物品３内には横断方向に拡がろうとする反発力が生じる。 In the regulation process, the size of the folded absorbent article 3 is regulated by the regulation unit 10B. That is, in the regulation unit 10 </ b> B, the absorbent article 3 that has been conveyed (folded) by the conveyance belt 25 is conveyed in the conveyance direction by the lower conveyance belt 31. At this time, in the pair of regulating members 33, the inner transverse distance ds1 of the upstream end portion 33a (FIG. 4A) is longer than the transverse width W1 of the absorbent article 3 before the regulating step and is absorbent. It is set to be long enough to absorb the displacement of the article 3 in the transverse direction. Therefore, the absorbent article 3 is easily inserted into the space 33 s regardless of whether or not there is a displacement in the transverse direction. And when the absorbent article 3 is conveyed in the space 33s from the upstream side to the downstream side, the inner transverse distance becomes shorter as it goes from the upstream side to the downstream side, so that the width in the transverse direction of the absorbent article 3 is increased. It is regulated by the regulating member 33 and becomes smaller. As a result, the width in the transverse direction of the absorbent article 3 is the same as the inner transverse distance de1 of the downstream end portion 33b of the regulating member 33 at the downstream end portion 33b of the regulating member 33 (FIG. 4B). And is carried out of the regulating member 33. As described above, the absorbent article 3 is passed between the pair of regulating members 33, whereby the width in the transverse direction is regulated to de1. In other words, as shown in FIG. 7C, the diaper of the absorbent article 3 has a transverse width of W2≈del, which is smaller than the transverse width W1 before the regulation step. Thereby, a repulsive force that spreads in the transverse direction is generated in the absorbent article 3.
　また、吸収性物品３の幅Ｗ２がｄｅ１であり、ｄｅ１≦第２の寸法Ｄ０１であることから、吸収性物品３を一対の規制部材３３の間を通過させることにより、吸収性物品３の横断方向の幅を第２の寸法Ｄ０１以下に容易に規制することができる。 Further, since the width W2 of the absorbent article 3 is de1, and de1 ≦ second dimension D01, the absorbent article 3 is crossed by passing the absorbent article 3 between the pair of regulating members 33. The width in the direction can be easily regulated to the second dimension D01 or less.
　規制ユニット１０Ｂでは、更に、下側搬送ベルト３１と上側規制手段３２において、上流側の端部（図４（Ａ））の内側上下距離ｄｓ２は、少なくとも規制工程前の吸収性物品３の上下方向の厚さＨ１よりも長く且つ吸収性物品３の上下方向の厚さのばらつきを吸収できる程度に長くなるように設定されている。したがって、吸収性物品３は上下方向についても空間３３ｓに容易に挿入される。そして、吸収性物品３が空間３３ｓ内を上流側から下流側へ搬送されるとき、内側上下距離が上流側から下流側に向かうに連れて短くなるので、吸収性物品３の上下方向の厚さがばらつきに拘らず下側搬送ベルト３１と上側規制手段３２で規制されて小さくなる。その結果、下側搬送ベルト３１と上側規制手段３２の下流側（図４（Ｂ））の端部３３ｂにおいて、吸収性物品３の上下方向の厚さが、下側搬送ベルト３１と上側規制手段３２の下流側の端部３３ｂの内側上下距離ｄｅ２になり、下側搬送ベルト３１と上側規制手段３２から搬出される。このように吸収性物品３は、下側搬送ベルト３１と上側規制手段３２との間に通されることにより、上下方向の厚さをｄｅ２に規制される。言い換えると、吸収性物品３のおむつは、図７（Ｃ）及び図９（Ｂ）に示すように上下方向の厚さがＨ２≒ｄｅ２となり、規制工程の前の上下方向の厚さＨ１よりも小さくなる。それにより、吸収性物品３内には上下方向に拡がろうとする反発力が生じる。 In the regulation unit 10B, further, in the lower conveyance belt 31 and the upper regulation means 32, the inner vertical distance ds2 of the upstream end (FIG. 4A) is at least the vertical direction of the absorbent article 3 before the regulation process. It is set to be longer than the thickness H1 and long enough to absorb the variation in the thickness of the absorbent article 3 in the vertical direction. Therefore, the absorbent article 3 is easily inserted into the space 33s in the vertical direction. And when the absorbent article 3 is conveyed in the space 33s from the upstream side to the downstream side, the inner vertical distance becomes shorter as it goes from the upstream side to the downstream side, so the thickness of the absorbent article 3 in the vertical direction Regardless of the variation, it is regulated by the lower conveying belt 31 and the upper regulating means 32 and becomes smaller. As a result, the thickness in the up-down direction of the absorbent article 3 at the end 33b on the downstream side (FIG. 4B) of the lower conveying belt 31 and the upper regulating means 32 is the lower conveying belt 31 and the upper regulating means. The inner vertical distance de2 of the end portion 33b on the downstream side of 32 is carried out from the lower conveying belt 31 and the upper regulating means 32. As described above, the absorbent article 3 is passed between the lower conveying belt 31 and the upper regulating means 32, so that the thickness in the vertical direction is regulated to de2. In other words, the diaper of the absorbent article 3 has a vertical thickness H2≈de2 as shown in FIGS. 7C and 9B, which is higher than the vertical thickness H1 before the regulation step. Get smaller. Thereby, a repulsive force is generated in the absorbent article 3 to spread in the vertical direction.
　また、吸収性物品３の厚さＨ２がｄｅ２であり、ｄｅ２≦第１の寸法Ｄ０２であることから、吸収性物品３を下側搬送ベルト３１と上側規制手段３２との間に通過させることにより、吸収性物品３の厚さを第１の寸法Ｄ０２以下に容易に規制することができる。また、上側規制手段３２で吸収性物品３の搬送を補助することで、一対の規制部材３３間で規制されて吸収性物品３の搬送速度が落ちることを回避できる。 Further, since the thickness H2 of the absorbent article 3 is de2, and de2 ≦ the first dimension D02, the absorbent article 3 is passed between the lower conveying belt 31 and the upper regulating means 32. The thickness of the absorbent article 3 can be easily regulated to the first dimension D02 or less. Moreover, it can avoid that the conveyance speed of the absorbent article 3 falls by being regulated between a pair of regulating members 33 by assisting conveyance of the absorbent article 3 by the upper side regulation means 32.
　吸収性物品３のおむつは、規制工程の前の横断方向の幅Ｗ１及び厚さＨ１の大きさや吸収性物品３の材質によって、吸収性物品３の大きさの規制のされ方としては種々の態様が考えられる。例えば、吸収性物品３の厚みＨ１が小さい場合などでは、吸収性物品３の上下方向の端の部分（例示：胴回り部３ａの上面又は下面の部分）が主に規制又は圧縮され、上下方向の中央の部分（例示：股部３ｂの吸収体）はあまり規制又は圧縮されない場合がある。一方、吸収性物品３の幅Ｗ１が大きい場合などでは、吸収性物品３の上下方向の端の部分が規制又は圧縮されるだけでなく、上下方向の中央の部分も同様に規制又は圧縮される場合がある。 The diaper of the absorbent article 3 has various modes as to how the size of the absorbent article 3 is regulated depending on the size of the width W1 and the thickness H1 in the transverse direction before the regulation step and the material of the absorbent article 3. Can be considered. For example, when the thickness H1 of the absorbent article 3 is small, the upper end portion (example: upper surface or lower surface portion of the waistline portion 3a) of the absorbent article 3 is mainly restricted or compressed, The central portion (example: absorbent body of the crotch portion 3b) may not be regulated or compressed so much. On the other hand, when the width W1 of the absorbent article 3 is large, not only the vertical end portion of the absorbent article 3 is restricted or compressed, but the central portion in the vertical direction is similarly restricted or compressed. There is a case.
　包装工程では、包装ユニット１０Ｃにより、大きさを規制された吸収性物品３が筒状の連続シートで包装される。すなわち、連続シート４ａは下側搬送ベルト３１よりも下方側から折り曲げ部材４３に供給され、搬送方向に搬送されつつ、折り曲げ部材４３により横断方向の両側端縁部を持ち上げられて、その両側端縁部を重ね合わされる。それにより搬送方向に延びる重なり部分を有する筒状の連続シート４ｂが形成され、横断方向の内側の寸法は、第２の寸法Ｄ０１となり、上下方向の内側の寸法は、第１の寸法Ｄ０２となる。一方、規制ユニット１０Ｂから搬送されてくる吸収性物品３は規制ユニット１０Ｂで幅がＷ２≒ｄｅ１≦Ｄ０１で、厚さがＨ２≒ｄｅ２≦Ｄ０２に規制されている。したがって、その規制された吸収性物品３は、折り曲げ部材４３内で筒状に形成されつつある連続シート４ｂへ容易に挿入される。その結果、吸収性物品３を内包した筒状の連続シート４ｂが形成される。 In the packaging process, the absorbent article 3 whose size is regulated is packaged by a cylindrical continuous sheet by the packaging unit 10C. That is, the continuous sheet 4a is supplied to the bending member 43 from the lower side of the lower conveyance belt 31, and while being conveyed in the conveyance direction, both side edge portions in the transverse direction are lifted by the bending member 43, and the both edge portions thereof The parts are overlapped. Thereby, a cylindrical continuous sheet 4b having an overlapping portion extending in the transport direction is formed, the inner dimension in the transverse direction is the second dimension D01, and the inner dimension in the vertical direction is the first dimension D02. . On the other hand, the absorbent article 3 conveyed from the regulation unit 10B is regulated by the regulation unit 10B so that the width is W2≈de1 ≦ D01 and the thickness is H2≈de2 ≦ D02. Therefore, the regulated absorbent article 3 is easily inserted into the continuous sheet 4 b that is being formed into a cylindrical shape within the bending member 43. As a result, a cylindrical continuous sheet 4b including the absorbent article 3 is formed.
　吸収性物品３を内包した筒状の連続シート４ｂは、搬送ベルト４５により搬送方向に搬送されつつ、縦シール器４４により連続シート４ｂ上に形成されている上述の重なり部分をシールされ、縦シール部分６（図１）が形成される。それにより、筒状の連続シート４ｂは横断方向の内側の寸法が概ね第２の寸法Ｄ０１であり、上下方向の内側の寸法が概ね第１の寸法Ｄ０２である形状に保持される。このとき、吸収性物品３のおむつには横断方向や上下方向に拡がろうとする反発力が生じており、図８（Ａ）及び図９（Ｃ）に示すように筒状の連続シート４ｂを内側から押し拡げるように突っ張らせている。したがって、吸収性物品３が筒状の連続シート４ｂにより周囲から押さえ付けられた状態となるので、それにより吸収性物品３を筒状の連続シート４ｂ内の所定の位置に位置決めできる。すなわち吸収性物品を筒状の連続シート内の所定の位置に固定できる。 The cylindrical continuous sheet 4b containing the absorbent article 3 is conveyed in the conveyance direction by the conveyance belt 45, and the above-described overlapping portion formed on the continuous sheet 4b is sealed by the vertical sealer 44, and the vertical seal Portion 6 (FIG. 1) is formed. Accordingly, the cylindrical continuous sheet 4b is held in a shape in which the inner dimension in the transverse direction is approximately the second dimension D01, and the inner dimension in the vertical direction is approximately the first dimension D02. At this time, the diaper of the absorbent article 3 has a repulsive force that spreads in the transverse direction or the up-down direction. As shown in FIGS. 8A and 9C, the cylindrical continuous sheet 4b is attached to the diaper. It is stretched to spread from the inside. Therefore, since the absorbent article 3 is pressed from the periphery by the cylindrical continuous sheet 4b, the absorbent article 3 can be positioned at a predetermined position in the cylindrical continuous sheet 4b. That is, the absorbent article can be fixed at a predetermined position in the cylindrical continuous sheet.
　接合工程では、吸収性物品３を内包する筒状の連続シートにおける吸収性物品の前後が接合されて包装品連結体８が形成される。すなわち、吸収性物品３を内包した筒状の連続シート４ｂは一対の搬送ベルト５１、５２の間に把持されつつ、搬送方向に横シール器５３まで更に搬送される。連続シート４ｂにおける互いに隣り合う吸収性物品３同士の間の部分が横シール器５３の一対の押圧部材５４、５５により横断方向にシールされて横シール部分５（図１）が形成され、横シール部分５に弱め線７（図１）が形成される。それにより、包装品連結体８が形成される。このとき、吸収性物品３のおむつは、図８（Ｂ）に示すように包装品連結体８の各包装品２を内側から押し拡げるように突っ張らせている。 In the joining step, the front and back of the absorbent article in the cylindrical continuous sheet containing the absorbent article 3 are joined to form the packaged article assembly 8. That is, the cylindrical continuous sheet 4b including the absorbent article 3 is further conveyed to the horizontal sealer 53 in the conveyance direction while being held between the pair of conveyance belts 51 and 52. The portion between the absorbent articles 3 adjacent to each other in the continuous sheet 4b is sealed in the transverse direction by the pair of pressing members 54, 55 of the transverse sealer 53 to form the transverse seal portion 5 (FIG. 1), and the transverse seal is formed. A weakening line 7 (FIG. 1) is formed in the portion 5. Thereby, the packaged article connection body 8 is formed. At this time, as shown in FIG. 8 (B), the diaper of the absorbent article 3 is stretched so that each packaged product 2 of the packaged product coupling body 8 is expanded from the inside.
　このとき、横シール部分５の形成に伴って筒状の連続シート４ｂ内の空気の一部が上流側へ流れていっても、吸収性物品３が位置決めされているので、上流側の筒状の連続シート４ｂ内の吸収性物品３の位置がずれ難くなる。それにより、その後の横シール部分５の形成において筒状の連続シート４ｂ内の吸収性物品３が横シール部分５に挟まれてしまう、という事態を防止できる。 At this time, since the absorbent article 3 is positioned even if a part of the air in the cylindrical continuous sheet 4b flows to the upstream side with the formation of the lateral seal portion 5, the upstream cylindrical shape is positioned. The position of the absorbent article 3 in the continuous sheet 4b becomes difficult to shift. Thereby, the situation that the absorbent article 3 in the cylindrical continuous sheet 4b will be pinched | interposed into the horizontal seal part 5 in subsequent formation of the horizontal seal part 5 can be prevented.
　切断工程では、包装品連結体８が包装品２の所定個数ごとに切断・分割されて連結包装製品１が形成される。すなわち、包装品連結体８が一対の搬送ベルト６１、６２の間に把持されつつ搬送方向に搬送され、一対のローラ６４、６５の間に把持されつつ搬送される。包装品連結体８を切断すべきでないときには、ローラ６４、６５は搬送ベルト６１、６２とほぼ同じ速度で包装品連結体８を搬送する。これに対し、包装品連結体８を切断すべきときには、ローラ６４、６５は搬送ベルト６１、６２よりも高速度で包装品連結体８を搬送する。その結果、包装品連結体８の上流側部分が搬送ベルト６１、６２により把持されているので、包装品連結体８が弱め線７に沿って切断される。このようにして、所定数の包装品２が連結された連結包装製品１が形成される。 In the cutting step, the packaged product assembly 8 is cut and divided into a predetermined number of the packaged product 2 to form the coupled packaged product 1. That is, the packaged article assembly 8 is conveyed in the conveying direction while being held between the pair of conveying belts 61 and 62, and is conveyed while being held between the pair of rollers 64 and 65. When the packaged article coupling body 8 is not to be cut, the rollers 64 and 65 convey the packaged article coupling body 8 at substantially the same speed as the conveyor belts 61 and 62. On the other hand, when the packaged article coupling body 8 is to be cut, the rollers 64 and 65 convey the packaged article coupling body 8 at a higher speed than the conveying belts 61 and 62. As a result, since the upstream portion of the packaged article coupling body 8 is gripped by the conveyor belts 61 and 62, the packaged article coupling body 8 is cut along the weakening line 7. In this way, a linked packaged product 1 in which a predetermined number of packaged products 2 are linked is formed.
　連結包装製品１は一対の搬送ベルト６６、６７の間に把持されつつ、搬送方向に搬送され、連結包装製品１を梱包する梱包装置まで搬送される。 The linked packaged product 1 is conveyed in the conveying direction while being gripped between the pair of conveying belts 66 and 67, and is conveyed to a packing device for packing the linked packaged product 1.
　以上のようにして、連結包装製品１が製造される。 As described above, the linked packaged product 1 is manufactured.
　上述されるように、本発明では、規制工程において吸収性物品３の上下方向の厚さを規制して第１の寸法Ｄ０２以下に小さくし、包装工程において内側の寸法が第１の寸法Ｄ０２である筒状の連続シート４ｂに、その吸収性物品３を収納しているので、筒状の連続シート４ｂが吸収性物品３により内側から押し拡げられて突っ張った状態になる。その結果、吸収性物品３が筒状の連続シート４ｂにより周囲から押さえ付けられた状態となり、吸収性物品３を筒状の連続シート４ｂ内の所定の位置に位置決めできる。すなわち吸収性物品３を筒状の連続シート４ｂ内の所定の位置に固定できる。 As described above, in the present invention, the thickness in the up-down direction of the absorbent article 3 is restricted in the restricting process to be smaller than the first dimension D02, and the inner dimension is the first dimension D02 in the packaging process. Since the absorbent article 3 is housed in a certain cylindrical continuous sheet 4b, the cylindrical continuous sheet 4b is pushed and expanded from the inside by the absorbent article 3. As a result, the absorbent article 3 is pressed from the periphery by the cylindrical continuous sheet 4b, and the absorbent article 3 can be positioned at a predetermined position in the cylindrical continuous sheet 4b. That is, the absorbent article 3 can be fixed at a predetermined position in the cylindrical continuous sheet 4b.
　吸収性物品３が位置決めされると、筒状の連続シート４ｂ内の吸収性物品３がその位置から前後左右に動き難くなり、したがって筒状の連続シート４ｂ内の吸収性物品３の重心の位置が前後左右にずれ難くなる。それにより、筒状の連続シート４ｂが包装ユニット１０Ｃから切断ユニット１０Ｅまで非常に長く連続的に延在し、複数の吸収性物品３を内包しつつ継続的に搬送方向に搬送されているときにも、搬送方向に対して全体的に横断方向にずれたり、蛇行したり、折れ曲がったりすることが起こり難くなり、それにより筒状の連続シート４ｂを搬送方向に安定して搬送することができる。 When the absorbent article 3 is positioned, the absorbent article 3 in the cylindrical continuous sheet 4b is difficult to move back and forth and from side to side, and therefore the position of the center of gravity of the absorbent article 3 in the cylindrical continuous sheet 4b. Is difficult to shift back and forth and left and right. Thereby, when the cylindrical continuous sheet 4b is continuously extended from the packaging unit 10C to the cutting unit 10E for a very long time and is continuously conveyed in the conveying direction while containing the plurality of absorbent articles 3. However, it is difficult for the entire sheet to shift, meander, or bend in the transverse direction with respect to the conveying direction, so that the cylindrical continuous sheet 4b can be stably conveyed in the conveying direction.
　また、吸収性物品３を筒状の連続シート４ｂ内の所定の位置に位置決めできると、筒状の連続シート４ｂ内の吸収性物品３が前後左右に動き難くなるので、製造された連結包装製品１においても吸収性物品３が包装袋４内で動き難くなる。それにより、連結包装製品１をダンボール箱のような梱包箱１００に詰め込むとき、包装袋４内で吸収性物品３のずれがほとんどないため、図１０（Ａ）や図１０（Ｂ）に示すように包装品２を梱包箱１００内に容易に整列させて配置することができる。それゆえ、輸送などで梱包箱が揺さぶられても、梱包箱１００内で包装品２の配置が乱され難くなるので、包装品２の一部が変形したり押し潰されたりして吸収性物品の吸収体が変形して吸収力が低下する、ということを防止できる。 Further, if the absorbent article 3 can be positioned at a predetermined position in the cylindrical continuous sheet 4b, the absorbent article 3 in the cylindrical continuous sheet 4b becomes difficult to move back and forth, and left and right. 1 also makes it difficult for the absorbent article 3 to move within the packaging bag 4. As a result, when the linked packaged product 1 is packed in a packaging box 100 such as a cardboard box, there is almost no deviation of the absorbent article 3 in the packaging bag 4, so as shown in FIG. 10 (A) and FIG. 10 (B). The packaged product 2 can be easily aligned and arranged in the packaging box 100. Therefore, even if the packaging box is shaken by transportation or the like, the arrangement of the packaged product 2 is not easily disturbed in the packaging box 100, so that the absorbent article is deformed or crushed. It can be prevented that the absorbent body is deformed and the absorption power is reduced.
　上記の実施の形態では、一対の規制部材３３又は３３Ｐで吸収性物品３の横断方向の幅を規制しているが、本実施の形態はこの例に限定されるものでは無い。例えば、吸収性物品３の横断方向の幅やその位置ずれが小さく、横断方向の規制が不要である場合、吸収性物品３の横断方向の幅を規制しなくてもよい。その場合、一対の規制部材３３又は３３Ｐを省略できる。 In the above embodiment, the width in the transverse direction of the absorbent article 3 is regulated by the pair of regulating members 33 or 33P, but the present embodiment is not limited to this example. For example, when the width in the transverse direction of the absorbent article 3 and its positional deviation are small and the regulation in the transverse direction is unnecessary, the width in the transverse direction of the absorbent article 3 does not have to be regulated. In that case, the pair of regulating members 33 or 33P can be omitted.
　上記の実施の形態では、図７（Ｂ）に示すように、少なくとも搬送方向の下流側に折り目ＦＬが位置するように吸収性物品３を折り畳んで搬送している。したがって、吸収性物品３の上下方向の厚さにばらつきがあっても、吸収性物品３が折り目ＦＬの部分を先端とするくさびのように機能して、下側搬送ベルト３１と上側規制手段３２との間の空間３３ｓの入口に容易に侵入できる。すなわち、下側搬送ベルト３１と上側規制手段３２との間に吸収性物品３の折り目ＦＬの部分を容易に挿入でき、それに伴って吸収性物品３全体を容易に挿入できる。このとき、上側規制手段３２がベルトやガイド板のように位置が固定的であるときには、吸収性物品３の搬送方向の上流側の部分が下側搬送ベルト３１と上側規制手段３２との間に入れずに捲れ上がる、ということを抑制できる。これらにより、吸収性物品３の上下方向の厚さを所定の寸法以下に容易に規制することができる。 In the above embodiment, as shown in FIG. 7B, the absorbent article 3 is folded and conveyed so that the fold line FL is positioned at least on the downstream side in the conveying direction. Therefore, even if there is variation in the thickness of the absorbent article 3 in the vertical direction, the absorbent article 3 functions like a wedge with the fold line FL at the tip, and the lower conveying belt 31 and the upper regulating means 32. Can easily enter the entrance of the space 33s between the two. That is, the portion of the fold FL of the absorbent article 3 can be easily inserted between the lower conveyance belt 31 and the upper regulating means 32, and the entire absorbent article 3 can be easily inserted accordingly. At this time, when the position of the upper regulating means 32 is fixed like a belt or a guide plate, the upstream portion of the absorbent article 3 in the conveying direction is between the lower conveying belt 31 and the upper regulating means 32. It is possible to suppress the drowning without entering. By these, the thickness of the up-down direction of the absorbent article 3 can be easily controlled below a predetermined dimension.
　また、上記の実施の形態では、吸収性物品３の折り畳みは１回だけであるが、本実施の形態はこの例に限定されるものでは無く、折り畳まなくてもよいし、２回以上折り畳んでもよい。２回以上折り畳む場合、上下方向の一番上になる折り目が吸収性物品３における下流側に位置するように吸収性物品３を搬送することが好ましい。それにより、吸収性物品３が一番上の折り目の部分を先端とするくさびのように機能して、下側搬送ベルト３１と上側規制手段３２との間の空間３３ｓの入口に容易に侵入できる。また、吸収性物品３における折り目よりも先の部分が上側規制手段３２により捲り上がることを抑制できる。 In the above embodiment, the absorbent article 3 is folded only once. However, the present embodiment is not limited to this example, and may not be folded, or may be folded two or more times. Good. In the case of folding twice or more, it is preferable to transport the absorbent article 3 so that the uppermost fold line is positioned on the downstream side of the absorbent article 3. Thereby, the absorbent article 3 functions like a wedge with the uppermost fold portion as a tip, and can easily enter the entrance of the space 33 s between the lower conveying belt 31 and the upper regulating means 32. . Moreover, it can suppress that the part ahead of the crease | fold in the absorbent article 3 rises by the upper side control means 32. FIG.
　また、上記の実施の形態では、図７（Ｂ）に示すように、少なくとも搬送方向に延びる弾性体３ｆを含む領域で折り目ＦＬを形成するように吸収性物品３を折り畳んでいる。したがって、弾性体３ｆを含まない領域で折り目ＦＬを形成するように吸収性物品３を折り畳むよりも、弾性体３ｆの弾性力により、折り畳んだ状態から元の状態に回復しようとする力が強くなり膨らもうとするため、折り畳んだときの吸収性物品３の上下方向の厚さが厚くなる。そのため、吸収性物品３は、規制工程で厚さが規制され、包装工程で筒状の連続シート４ｂに内包されると、弾性体３ｆの弾性力により、筒状の連続シート４ｂをその内側からより押し拡げてより突っ張った状態にする。それにより吸収性物品３を筒状の連続シート４ｂ内の所定の位置により確実に位置決めできる。 Further, in the above embodiment, as shown in FIG. 7B, the absorbent article 3 is folded so as to form the fold FL at least in the region including the elastic body 3f extending in the transport direction. Therefore, rather than folding the absorbent article 3 so as to form the fold FL in a region that does not include the elastic body 3f, the force for restoring the folded state to the original state is increased by the elastic force of the elastic body 3f. In order to swell, the thickness of the absorbent article 3 in the up-down direction when folded is increased. Therefore, when the thickness of the absorbent article 3 is regulated in the regulation process and is included in the cylindrical continuous sheet 4b in the packaging process, the cylindrical continuous sheet 4b is pulled from the inside by the elastic force of the elastic body 3f. Make it more stretched and stretched. Thereby, the absorbent article 3 can be reliably positioned at a predetermined position in the cylindrical continuous sheet 4b.
　また、上記の実施の形態では、図７（Ｂ）に示すように、少なくとも吸収体における横断方向の幅が最も狭い箇所３ｇ以外の箇所で折り目ＦＬを形成するように吸収性物品３を折り畳んでいる。したがって、その幅が最も狭い箇所３ｇで折り目ＦＬを形成するように吸収性物品３を折り畳むよりも、折り畳んだ状態から元の状態に回復しようとする力が強くなり膨らもうとするため、折り畳んだときの吸収性物品３の上下方向の厚さが厚くなる。そのため、吸収性物品３は、規制工程で厚さが規制され、包装工程で筒状の連続シート４ｂに内包されると、吸収体の弾力により、筒状の連続シート４ｂをその内側からより押し拡げてより突っ張った状態にする。それにより吸収性物品３を筒状の連続シート４ｂ内の所定の位置により確実に位置決めできる。 Moreover, in said embodiment, as shown in FIG.7 (B), the absorbent article 3 is folded so that the crease | fold FL may be formed at places other than the location 3g where the width of the crossing direction in an absorber is the narrowest at least. Yes. Therefore, the folding of the absorbent article 3 so as to form the crease FL at the narrowest portion 3g has a stronger force to recover from the folded state to the original state, so In this case, the thickness of the absorbent article 3 in the vertical direction increases. Therefore, when the thickness of the absorbent article 3 is regulated in the regulation process and is enclosed in the cylindrical continuous sheet 4b in the packaging process, the cylindrical continuous sheet 4b is pushed from the inside by the elasticity of the absorber. Expand and make it more stretched. Thereby, the absorbent article 3 can be reliably positioned at a predetermined position in the cylindrical continuous sheet 4b.
　また、上記の実施の形態では、図７（Ｂ）に示すように、少なくとも平面視での面積の広い胴回り部３ａが下側に位置するように吸収性物品３を折り畳んでいる。したがって、搬送ベルト２５や下側搬送ベルト３１等との接地面積が広くなり、安定的に吸収性物品３を搬送することができる。特に規制工程では、上側規制手段３２により吸収性物品３の厚さが規制されるため、搬送に影響が出るおそれがあるが、本実施の形態では、下側搬送ベルト３１との接地面積が広くなるため、規制の影響をほとんど受けずに安定的に吸収性物品３を搬送することができる。 Further, in the above embodiment, as shown in FIG. 7B, the absorbent article 3 is folded so that the waistline portion 3a having a large area in a plan view is positioned on the lower side. Therefore, the contact area with the conveyor belt 25, the lower conveyor belt 31 and the like is increased, and the absorbent article 3 can be stably conveyed. In particular, in the regulation process, the thickness of the absorbent article 3 is regulated by the upper regulation means 32, which may affect the conveyance. In this embodiment, the ground contact area with the lower conveyance belt 31 is wide. Therefore, the absorbent article 3 can be stably conveyed with almost no influence of regulations.
　次に、本発明の別の実施の形態について説明する。図１１～図１４は別の実施の形態の吸収性物品の構成例を模式的に示す図であり、図１１は平面図、図１２は図１１のＸＸ’部分断面図、図１３は図１１のＱ領域の拡大図、図１４は、図１３のＹＹ’部分断面図である。吸収性物品３は図１１に示すおむつであり、吸収体３Ｐは、その長手方向の一方の端部を胴回り部３ａの腹側面３ａ１に、他方の端部を胴回り部３ａの背側面３ａ２に、それら両端部の間の部分を股部３ｂの腹側の部分３ｂ１及び背側の部分３ｂ２にそれぞれ載置され接着されている。吸収体３Ｐは、その短手方向の両側端縁３ＳＡ１の外側に側方吸収部３Ｐ１を備えている。 Next, another embodiment of the present invention will be described. 11 to 14 are diagrams schematically showing a configuration example of an absorbent article according to another embodiment, in which FIG. 11 is a plan view, FIG. 12 is a partial cross-sectional view of XX ′ in FIG. 11, and FIG. FIG. 14 is an enlarged view of the Q region, and FIG. 14 is a partial cross-sectional view of FIG. The absorbent article 3 is a diaper shown in FIG. 11, and the absorbent body 3P has one end portion in the longitudinal direction on the abdominal side surface 3a1 of the waistline portion 3a, and the other end portion on the back side surface 3a2 of the waistline portion 3a. The portions between both ends are placed and bonded to the belly side portion 3b1 and the back side portion 3b2 of the crotch portion 3b, respectively. The absorber 3P includes a side absorbent portion 3P1 on the outer side of both side edges 3SA1 in the short direction.
　図１２に示すように、吸収体３Ｐは、液透過性のトップシート３ＳＴと、液不透過性のバックシート３ＳＢと、トップシート３ＳＴとバックシート３ＳＢとの間に配置された吸収体本体３ＳＡとを備えている。 As shown in FIG. 12, the absorbent body 3P includes a liquid-permeable top sheet 3ST, a liquid-impermeable back sheet 3SB, and an absorbent body 3SA disposed between the top sheet 3ST and the back sheet 3SB. It has.
　側方吸収部３Ｐ１には、おむつ着用時に、トップシート３ＳＴ側に凸に屈曲する屈曲部分３Ｕとバックシート３ＳＢ側に凸に屈曲する屈曲部分３Ｖとが形成されている。屈曲部分３Ｕ、３Ｖの各々には、その両側の隣接する部分よりも吸収体材料３ＳＡ０の坪量が低くて厚みが小さい低坪量部３ＳＡ２が形成されている。屈曲部分３Ｕと屈曲部分３Ｖと低坪量部３ＳＡ２とは、吸収体３Ｐの長手方向に沿って延設されている。屈曲部分３Ｕのバックシート３ＳＢ側には、弾性部材３ＳＡ３が、低坪量部３ＳＡ２に埋め込まれて、吸収体３Ｐの長手方向に延設されている。低坪量部３ＳＡ２の両側の隣接する部分におけるトップシート３ＳＴ側の面及びバックシート３ＳＢ側の面はそれぞれトップシート３ＳＴ及びバックシート３ＳＢと接着剤３Ｊにより接合されている。そのため、おむつ着用時に側方吸収部３Ｐ１が可撓溝３Ｋで屈曲した際にも、側方吸収部３Ｐ１は、トップシート３ＳＴ及びバックシート３ＳＢと一体性が保たれるようになっている。 The side absorbing portion 3P1 is formed with a bent portion 3U bent convexly toward the top sheet 3ST and a bent portion 3V bent convexly toward the backsheet 3SB when the diaper is worn. In each of the bent portions 3U and 3V, a low basis weight portion 3SA2 having a lower basis weight and a smaller thickness of the absorbent material 3SA0 than the adjacent portions on both sides thereof is formed. The bent portion 3U, the bent portion 3V, and the low basis weight portion 3SA2 are extended along the longitudinal direction of the absorber 3P. On the back sheet 3SB side of the bent portion 3U, an elastic member 3SA3 is embedded in the low basis weight portion 3SA2 and extends in the longitudinal direction of the absorber 3P. The surface on the top sheet 3ST side and the surface on the back sheet 3SB side in adjacent portions on both sides of the low basis weight portion 3SA2 are joined to the top sheet 3ST and the back sheet 3SB with an adhesive 3J, respectively. Therefore, even when the side absorbent part 3P1 is bent by the flexible groove 3K when the diaper is worn, the side absorbent part 3P1 is kept integrated with the top sheet 3ST and the back sheet 3SB.
　この吸収性物品３のおむつによれば、その着用時に、少なくとも股部３ｂの側方吸収部３Ｐ１において、屈曲部分３Ｕ、３Ｖが、低坪量部３ＳＡ２に沿って屈曲する。その結果、吸収体３Ｐの短手方向の中央部から側端縁へ移動した体液は、吸収体３Ｐの長手方向に延びる屈曲部分３Ｖに沿って移動して、側方吸収部３Ｐ１の全体で吸収され、且つ吸収体３Ｐの長手方向に延びる屈曲部分３Ｕにより、吸収体３Ｐの短手方向への移動が阻止されるため、股部３ｂにおける横漏れが防止される。 According to the diaper of the absorbent article 3, the bent portions 3U and 3V bend along the low basis weight portion 3SA2 at least in the side absorbent portion 3P1 of the crotch portion 3b when worn. As a result, the bodily fluid that has moved from the lateral center of the absorbent body 3P to the side edge moves along the bent portion 3V that extends in the longitudinal direction of the absorbent body 3P, and is absorbed by the entire lateral absorbent section 3P1. In addition, the bent portion 3U extending in the longitudinal direction of the absorbent body 3P prevents the absorbent body 3P from moving in the short direction, thereby preventing side leakage at the crotch portion 3b.
　本実施の形態では、この吸収性物品３（おむつ）を股部３ｂで二つ折りにして図７（Ａ）に示すパンツ型おむつとしている。そのパンツ型おむつでは、吸収体３Ｐの長手方向に沿う低坪量部３ＳＡ２が吸収体３Ｐに形成されており、折り畳み工程において、折り目ＦＬが低坪量部３ＳＡ２を横断するようにおむつが折り畳まれる。 In the present embodiment, the absorbent article 3 (diaper) is folded in half at the crotch portion 3b to form a pants-type diaper shown in FIG. In the pants-type diaper, the low basis weight portion 3SA2 along the longitudinal direction of the absorber 3P is formed in the absorber 3P, and the diaper is folded so that the crease FL crosses the low basis weight portion 3SA2 in the folding step. .
　このように、本実施の形態では、少なくとも吸収体３Ｐ上の低坪量部３ＳＡ２を横断するように吸収性物品３を折り畳んでいる。そのため、その低坪量部３ＳＡ２を横断しないように吸収性物品を折り畳むよりも、折り目ＦＬが低坪量部３ＳＡ２に遮断されて、折り畳まれた部分が開き易くなり、折り畳んだときの吸収性物品３の上下方向の厚さが厚くなる。そのため、吸収性物品３は、規制工程で厚さが規制され、包装工程で筒状の連続シート４ｂに内包されると、折り畳まれた部分の開き易さにより、吸収性物品３が筒状の連続シート４ｂをその内側からより押し拡げてより突っ張った状態にする。それにより吸収性物品３を筒状の連続シート４ｂ内の所定の位置により確実に位置決めできる。 Thus, in the present embodiment, the absorbent article 3 is folded so as to cross at least the low basis weight portion 3SA2 on the absorber 3P. Therefore, rather than folding the absorbent article so as not to cross the low basis weight portion 3SA2, the crease FL is blocked by the low basis weight portion 3SA2, and the folded portion is easily opened, and the absorbent article when folded is folded. The thickness in the vertical direction of 3 is increased. Therefore, if the thickness of the absorbent article 3 is regulated in the regulation process and is included in the cylindrical continuous sheet 4b in the packaging process, the absorbent article 3 has a cylindrical shape due to the ease of opening the folded portion. The continuous sheet 4b is pushed and expanded from the inside to be in a more stretched state. Thereby, the absorbent article 3 can be reliably positioned at a predetermined position in the cylindrical continuous sheet 4b.
　また、図１３及び図１４に示すように、胴回り部３ａは伸縮部を腹側面３ａ１に備えている。伸縮部は、肌当接面側及び非肌当接面側にそれぞれ配置された肌側シート３ａ１－１及び非肌側シート３ａ１－２と、それら両シート３ａ１－１、３ａ１－２間に胴回り方向に配設された弾性体３ｅとを含んでいる。肌側シート３ａ１－１と非肌側シート３ａ１－２とは胴回り方向に延在する横長接合部３Ｍにより互いに接合されている。横長接合部３Ｍは胴回り方向に間欠的に形成され、横長接合部列３Ｍ０を構成している。また、肌側シート３ａ１－１と非肌側シート３ａ１－２とは胴回り方向と交差する方向に延在する縦長接合部３Ｎにより更に互いに接合されている。縦長接合部３Ｎは胴回り方向に間欠的に形成され、縦長接合部列３Ｎ０を形成している。横長接合部３Ｍ及び縦長接合部３Ｎは伸縮部に混在している。 Moreover, as shown in FIG.13 and FIG.14, the trunk part 3a is equipped with the expansion-contraction part in the abdominal side surface 3a1. The expansion / contraction part includes a skin-side sheet 3a1-1 and a non-skin-side sheet 3a1-2 disposed on the skin contact surface side and the non-skin contact surface side, respectively, and a waistline between the both sheets 3a1-1 and 3a1-2. And an elastic body 3e disposed in the direction. The skin side sheet 3a1-1 and the non-skin side sheet 3a1-2 are joined to each other by a horizontally long joining portion 3M extending in the waistline direction. The horizontally long joint portion 3M is intermittently formed in the waistline direction and constitutes a horizontally long joint portion row 3M0. Further, the skin side sheet 3a1-1 and the non-skin side sheet 3a1-2 are further joined to each other by a vertically long joining portion 3N extending in a direction intersecting the waistline direction. The vertically long joint portions 3N are intermittently formed in the waistline direction to form a vertically long joint portion row 3N0. The horizontally long joint portion 3M and the vertically long joint portion 3N are mixed in the stretchable portion.
　この吸収性物品３のおむつによれば、横長接合部列３Ｍ０を構成する横長接合部３Ｍ同士の間から、着用者の汗が、おむつの縦方向に流れたとしても、隣り合う横長接合部列３Ｍ０の横長接合部３Ｍによって、縦方向の流れを抑制することができる。そのため、汗がおむつの縦方向に流れていく時間を稼ぐことができる。その結果、汗の蒸散性を更に向上させることができるとともに縦方向に流れる不快感を更に軽減することができる。また縦長接合部列３Ｎ０を構成する縦長接合部３Ｎ同士の間から、着用者の汗が、おむつの胴回り方向に拡散したとしても、隣り合う縦長接合部列３Ｎ０の縦長接合部３Ｎによって、胴回り方向の拡散を抑制することができる。そのため、汗がおむつの胴回り方向に拡散していく時間を稼ぐことができる。その結果、汗の蒸散性を更に向上させることができるとともに胴回り方向に流れる不快感を更に軽減することができる。 According to the diaper of this absorbent article 3, even if the wearer's sweat flows in the vertical direction of the diaper from between the horizontally long joint portions 3M constituting the horizontally long joint portion row 3M0, the adjacent horizontally long joint portion rows The flow in the vertical direction can be suppressed by the 3M0 horizontally long joint portion 3M. Therefore, it is possible to earn time for the sweat to flow in the vertical direction of the diaper. As a result, the transpiration of sweat can be further improved and the discomfort flowing in the vertical direction can be further reduced. Further, even if the wearer's sweat diffuses between the longitudinal joint portions 3N constituting the longitudinal joint portion row 3N0 in the waist circumference direction of the diaper, the longitudinal joint portion 3N of the adjacent longitudinal joint portion row 3N0 causes the waist circumference direction. Can be suppressed. Therefore, it is possible to earn time for sweat to diffuse in the direction of the waist of the diaper. As a result, the transpiration of sweat can be further improved and the discomfort flowing in the waistline direction can be further reduced.
　本実施の形態のパンツ型おむつでは、折り畳み工程において、折り目ＦＬが胴回り部３ａを横断するように折り畳まれていてもよい。 In the pants-type diaper of the present embodiment, the fold line FL may be folded so as to cross the waistline portion 3a in the folding process.
　このように少なくとも胴回り部３ａを横断するように吸収性物品３を折り畳む場合、胴回り部３ａを横断しないように吸収性物品３を折り畳む場合よりも、胴回り部３ａの弾力により、折り畳まれた部分が開き易くなり、折り畳んだときの吸収性物品３の上下方向の厚さが厚くなる。そして、規制工程で厚さが規制され、包装工程で筒状の連続シート４ｂに内包されると、胴回り部３ａの弾力により、吸収性物品が筒状の連続シート４ｂをその内側からより押し拡げてより突っ張った状態にする。それにより吸収性物品３を筒状の連続シート内４ｂの所定の位置により確実に位置決めできる。 In this way, when the absorbent article 3 is folded so as to cross at least the waistline portion 3a, the folded portion is more elastic due to the elasticity of the waistline portion 3a than when the absorbent article 3 is folded so as not to cross the waistline portion 3a. It becomes easy to open, and the thickness of the absorbent article 3 in the vertical direction when it is folded is increased. Then, when the thickness is regulated in the regulation process and is encapsulated in the cylindrical continuous sheet 4b in the packaging process, the absorbent article pushes the cylindrical continuous sheet 4b further from the inside by the elasticity of the waistline portion 3a. To make it more stretched. Thereby, the absorbent article 3 can be reliably positioned at a predetermined position in the cylindrical continuous sheet 4b.
