As shown in FIG. 5, the holding surface 53 is arranged in the rotational radius direction of the rotary drum 42. It faces outward. As shown in FIG. 6A, a plurality of intake holes 54 (corresponding to holes) are formed in the holding surface 53 over almost the entire surface, and these intake holes 54 are formed in the intake chamber 56 inside the work holding pallet 51, It connects with the negative pressure zone Z1 mentioned later through pipe lines, such as the intake pipe 81. FIG. Therefore, suction force for holding the absorbent main body 10 is generated on the holding surface 53 by the intake air from the intake holes 54. This intake operation is performed over the range from the receiving position Qin to the delivery position Qout in FIG. 5 and is generally stopped in other ranges. This intake operation will be described later.
- the longitudinal direction of the holding surface 53 is aligned with the longitudinal direction of the workpiece holding pallet 51. Therefore, as will be described later, if the longitudinal direction of the work holding pallet 51 at the receiving position Qin is directed to the MD direction, the absorbent main body 10 is sent from the cutter device 61 in a state where the longitudinal direction is directed to the MD direction. Can be firmly held by the holding surface 53. Furthermore, as shown in FIG. 6A, the holding surface 53 is formed in a circular arc shape along the longitudinal direction, and its radius of curvature R53 is substantially the same as the rotational radius of the circular orbit Tr in FIG.

If the angular velocity ⁇ of the rotating drum 42 is set so as to be equal to the conveying speed V10a of the continuous body 10a, the work holding pallet 51 can remove the absorbent main body 10 sent from the cutter device 61 almost over its entire length. It can be received in the stretched state without.

吸収性物品に係るシート状部材の複合体を製造する装置であって、
保持面を備えた保持部を有し、
前記保持部は、前記保持部の保持面に第1シート状部材を保持し、前記保持面から前記第1シート状部材を第2シート状部材に引き渡して取り付け、
前記保持面に形成された複数の孔からの吸気によって前記保持面に保持された前記第1シート状部材は、前記第2シート状部材への引き渡しの際に、先に引き渡される部分と、後に引き渡される部分と、を有し、
前記保持部は、前記先に引き渡される部分を吸引する孔に連通する第1吸気室と、前記後に引き渡される部分を吸引する孔に連通する第2吸気室との2つの吸気室を少なくとも有し、
前記保持部は、前記第1吸気室と前記第2吸気室とが互いに通気不能に区画された状態で、前記第1シート状部材を前記第2シート状部材に引き渡すことを特徴とする吸収性物品に係るシート状部材の複合体の製造装置である。
保持部の保持面に第1シート状部材を保持することと、前記保持面から前記第1シート状部材を第2シート状部材に引き渡して取り付けることと、を有し、
前記保持面に形成された複数の孔からの吸気によって前記保持面に保持された前記第1シート状部材は、前記第2シート状部材への引き渡しの際に、先に引き渡される部分と、後に引き渡される部分と、を有し、
前記保持部は、前記先に引き渡される部分を吸引する孔に連通する第1吸気室と、前記後に引き渡される部分を吸引する孔に連通する第2吸気室との2つの吸気室を少なくとも有し、
前記第1吸気室と前記第2吸気室とが互いに通気不能に区画された状態で、前記第1シート状部材を前記第2シート状部材に引き渡すことを特徴とする吸収性物品に係るシート状部材の複合体の製造方法。
前記先に引き渡される部分の前記第2シート状部材への引き渡し動作に対応させて、当該先に引き渡される部分を吸引する孔の吸気が弱められ、
前記後に引き渡される部分の前記第2シート状部材への引き渡し動作に対応させて、当該後に引き渡される部分を吸引する孔の吸気が弱められるのが望ましい。
このような吸収性物品に係るシート状部材の複合体の製造方法によれば、第1シート状部材において孔が担当する部分の引き渡し動作に対応させて、前記孔の吸気を弱めるので、前記孔の吸引力を弱めて、保持面から第2シート状部材への第1シート状部材の引き渡しを速やかに行うことができる。
前記吸気を弱めた孔は、弱めた順番で前記第1シート状部材へ向けて空気を噴き出すのが望ましい。
このような吸収性物品に係るシート状部材の複合体の製造方法によれば、第1シート状部材において引き渡し済みであるべき部分に対応する孔は、順次空気を吹き出すので、前記引き渡し済みであるべき部分への吸引力を完全に消滅させることができて、その結果、保持面から第2シート状部材への第1シート状部材の引き渡しをより速やかに行うことができる。
前記保持部における前記第1吸気室と前記第2吸気室との間の位置には、前記第3吸気室が区画されており、
前記第1吸気室に連通する孔と、前記第2吸気室に連通する孔との間に位置させて、前記第3吸気室に連通する孔が形成されており、
前記第1吸気室、前記第2吸気室、及び前記第3吸気室が互いに通気不能に区画された状態で、前記第1シート状部材を前記第2シート状部材に引き渡すのが望ましい。
このような吸収性物品に係るシート状部材の複合体の製造方法によれば、前記保持面の孔の吸引動作を更に細分化して行うことができるので、保持面は、一連の引き渡し動作の最初から最後までに亘り、第1シート状部材を確実に保持可能となる。
前記保持部は、周回軌道に沿って移動し、
前記第2シート状部材は、前記周回軌道における引き渡し位置のローラーに掛け回されて連続して走行する連続シートであり、
前記保持部が前記引き渡し位置を、前記第2シート状部材の走行方向に沿って通過する際に、前記保持部の保持面の前記第1シート状部材が、前記第2シート状部材へと引き渡され、
引き渡す際に前記保持面において前記周回軌道の下流側となるエリアに、前記先に引き渡される部分を吸引する孔が形成されており、前記保持面において上流側となるエリアに、前記後に引き渡される部分を吸引する孔が形成されているのが望ましい。
このような吸収性物品に係るシート状部材の複合体の製造方法によれば、前記保持部が前記引き渡し位置を通過する際に、前記保持部から前記第2シート状部材へと前記第1シート状部材を速やかに引き渡すことができる。
前記先に引き渡される部分と前記後に引き渡される部分とのそれぞれには、これらの部分を互いに同じ方向に収縮する弾性部材が固定されており、
前記孔の吸気により前記第1シート状部材が前記保持面に吸着された状態においては、前記先に引き渡される部分及び後に引き渡される部分が、対応する前記弾性部材からの収縮力に抗して伸長した状態で保持されているのが望ましい。
このような吸収性物品に係るシート状部材の複合体の製造方法によれば、本製造方法の作用効果を有効に享受できる。すなわち、本製造方法によれば、前記先に引き渡される部分の引き渡し後に起こり得る、前記後に引き渡される部分に係る孔の吸引力の低下を有効に防ぐことができるので、前記先に引き渡される部分の引き渡し後にあっても、前記後に引き渡される部分の伸長状態は保持面上において有効に維持される。その結果、引き渡し過程における前記先に引き渡される部分と前記後に引き渡される部分との収縮差を抑えることができて、第2シート状部材への取り付け精度の向上を図れる。
前記第1吸気室及び前記第2吸気室は、前記保持部の内部において互いに通気不能な室状に区画されているのが望ましい。
このような吸収性物品に係るシート状部材の複合体の製造方法によれば、前記第1吸気室及び前記第2吸気室は、互いに通気不能な室状に前記保持部の内部に区画されているので、一連の引き渡し動作の最初から最後までに亘り、保持面は第1シート状部材を確実に保持可能となる。
吸収性物品に係るシート状部材の複合体を製造する装置であって、
保持面を備えた保持部を有し、
前記保持部は、前記保持面に第1シート状部材を保持し、前記保持面から前記第1シート状部材を第2シート状部材に引き渡して取り付け、
前記保持面に形成された複数の孔からの吸気によって前記保持面に保持された前記第1シート状部材は、前記第2シート状部材への引き渡しの際に、先に引き渡される部分と、後に引き渡される部分と、を有し、
前記保持部は、前記先に引き渡される部分を吸引する孔に連通する第1吸気室と、前記後に引き渡される部分を吸引する孔に連通する第2吸気室との2つの吸気室を少なくとも有し、
前記保持部は、前記第1吸気室と前記第2吸気室とが互いに通気不能に区画された状態で、前記第1シート状部材を前記第2シート状部材に引き渡すことを特徴とする吸収性物品に係るシート状部材の複合体の製造装置。
このような吸収性物品に係るシート状部材の複合体の製造装置によれば、第1吸気室と第2吸気室とが互いに通気不能に区画された状態において、前記第1シート状部材を前記第2シート状部材に引き渡す。よって、引き渡しの際に、第1吸気室の吸気状態が第2吸気室に及ぼす影響を小さくすることができる。すなわち、前記先に引き渡される部分の第2シート状部材への引き渡し後に起こり得る、前記後に引き渡される部分に係る孔の吸引力の低下を有効に防ぐことができて、その結果、一連の引き渡し動作の最初から最後までに亘り、保持面は第1シート状部材を確実に保持可能となる。よって、第1シート状部材の変形等を有効に抑えて、取り付け精度の向上を図れる。
本実施形態の吸収性物品1に係る連続シートの複合体1aの製造方法及び製造装置31は、例えば、使い捨ておむつ1の製造ラインに適用されている。
図1乃至図3は使い捨ておむつ1の説明図である。図1はおむつ1の平面図であり、図2Aは図1中のII-II断面図であり、図2Bは、おむつ1の別態様の同断面図である。図3はおむつ1の斜視図である。
図5に示すように、カッター装置61は、CD方向に沿った軸芯C61a,C61b周りに所定の周速V61で連続して駆動回転する上下一対のロール61a,61bを有する。周速V61は、例えば吸収性本体の連続体10aの搬送速度V10aとほぼ同速に設定される。
回転ドラム装置41は、CD方向に沿った軸心C41周りに駆動回転する回転ドラム42と、吸収性本体10を保持すべく、回転ドラム42の外周面に周方向に等ピッチで並んで支持された複数枚(図示例では8枚)のワーク保持パレット51(保持部に相当)と、を有している。
図7Aは、引き渡し位置Qoutに配置された搬送ローラー71の拡大図であり、図7Bは図7A中のB-B断面図である。搬送ローラー71は、CD方向を向いた軸心C71周りに回転自在に支持された従動ローラー71である。その外周面には、一対の帯部材の連続体20a,24aが掛け回されており、同連続体20a,24aの走行に伴って従動回転する。なお、一対の帯部材の連続体20a,24aの走行速度V20a(搬送速度)は、回転ドラム42のワーク保持パレット51の前記移動速度V51と略同値に設定されている。
図8A乃至図8Eは、引き渡し位置Qoutで行われる吸収性本体10の引き渡しの様子の説明図である。
