Description
前記基材シート同士を超音波接合により接合することで、接着剤の使用が不要となる。
前記2枚の不織布が重なり合った状態で、前記2枚の不織布を搬送するアンビルロールと、
前記アンビルロールに形成され前記アンビルロールの径方向の外方に向かって突出する複数の突部と、
超音波振動することにより前記複数の各突部との間で前記2枚の不織布を接合して接合部を形成するホーンとを備え、
ここにおいて、前記アンビルロールは、
前記不織布を搬送するために、かつ、前記突部上の不織布に前記粒状体が配置されるのを抑制するために、前記不織布を通して第1エアを前記粒状体および前記不織布と共に吸引する少なくとも1つの吸引孔と、
前記複数の突部と前記吸引孔との間に設けられ、前記アンビルロールの径方向の外方に向かって突出し、前記突部の突出高さよりも低い突出高さで、かつ、前記吸引孔の外周に沿って延びる突条とを定義する。
したがって、超音波溶着の際に前記突部の近傍において前記不織布上に前記粒状体が残留していても、前記アンビルロールに接する不織布および前記粒状体が前記不織布と共に前記突部と突条との間の空間に向かって逃げることができ、前記アンビルロールの突部とホーンとの間に前記粒状体が噛みこむおそれがないだろう。
この場合、超音波溶着の際に前記粒状体と前記アンビルロールに接する不織布とが前記溝に向って逃げ易い。
前記突条がループ状である場合、前記吸引孔に吸引されるエアの吸引力により前記2枚の不織布のうち前記アンビルロールに接する不織布が前記突条に接し易いだろう。
以下、本発明の実施例1が図面にしたがって説明される。
図1〜図9は実施例1を示す。
図1に示すように、本実施例の着用物品100は、吸収性本体(吸収性物品の一例)200、前胴回り部301および後胴回り部302を備えている。前記吸収性本体200は、着用者の前胴を覆うフロント部201、着用者の後胴を覆うバック部202、ならびに、前記フロント部201とバック部202との間の股間を覆う股部203を有している。
また、吸収性本体200には、着用者の脚部に沿って括れた脚回り部を形成してもよい。
なお、各図において溶着部位はxxや小さな黒い長方形で示される。
なお、図1〜図4において粒状体3は多数の微細なドットで示される。
また、各溶着ラインLは完全に連なっている必要はなく、各集合グループ30の粒状体3が他の集合グループ30に移動しにくい程度に溶着部位が断続的に形成されていてもよい。
すなわち、低強度接合部W3における不織布21,22の溶着力は、第1および第2高強度接合部W1,W2における溶着力よりも小さい。
これにより、使用前の吸収性本体200の厚さが小さくても、多量の体液を吸収することができる。
図4に示すように、本装置はアンビルロール4のまわりに、供給装置5、第1、第2導入ロール71,72および超音波ホーン81を備える。
前記吸収性本体200における前記トップシート21およびカバーシート22(図2)は、それぞれ、前記キャリアウエブ1およびカバーウエブ2から生成される。
前記無数の粒状体3の供給はキャリアウエブ1の単位面積当りにつき所定量ずつ断続的ないし連続的に供給される。
図6Aおよび図6Bのように、前記吸引孔40は複数設けられ、かつ、所定のパターンで配置される図1の複数の配置エリアDを定義するように設けられている。前記複数の配置エリアDは前記粒状体の集合を区画して配置するためのエリアである。
なぜならば、供給装置5から供給される粒状体3の供給幅が吸収性本体200における粒状体3の配置幅とほぼ同じ幅で供給される場合、キャリアウエブ1の周縁には粒状体3がほとんど供給されないため、吐出孔42の形成は不要となる。
なお、前記第1突部44Aに、第1突部44Bおよび第2突部45と同様の前記吐出孔42が形成されていてもよい。
図4および図8に示すように、前記供給装置5から前記キャリアウエブ1上に供給された粒状体3は配置装置(吸引孔40および吐出孔42)により前記キャリアウエブ1が下流へ搬送されるに従い各集合グループ30に互いに区画される。すなわち、吸引孔40は前記不織布1を搬送するために、かつ、前記突部44A,44B,45上の不織布1に前記粒状体3が配置されるのを抑制するために、前記粒状体3を前記不織布1と共に吸引する。
こうしてアンビルロール4は前記サンドイッチ構造体20を搬送する。
なお、図6Bのアンビルロール4の吸引孔40に吸引される第1エアα1により前記第2面12および粒状体3上に導入された前記カバーウエブ2はアンビルロール4の内側に向って凹んでいる。
一方、図1の前記内側領域Aに前記第2高強度接合部W2を形成するために、図6Aの第1突部44Bが前記アンビルロール4に配置されている。
前記低強度接合部W3が前記第1高強度接合部W1に囲まれた内側領域Aに形成されるように、図6Aの前記第2突部45が前記アンビルロール4に配置されている。
図8および図7A(濃い網点で示す)のように、前記吸引孔40の周縁には、たとえば吸引孔40の全周にわたって突条6が設けられている。
本実施例の場合、図7Aの前記突条6は前記吸引孔40の全周を囲うように連続的に設けられているが、図7Bのように、断続的にループ状に設けられていてもよい。
図4に示すように、第1導入ロール71によりキャリアウエブ1がアンビルロール4に導入されキャリアウエブ1の第1面11がアンビルロール4の搬送面41で吸着保持されながら、前記キャリアウエブ1が所定の搬送経路つまり前記搬送ドラム4の搬送面41に沿って搬送される。
図8に示されるアンビル4Rに形成された前記吸引孔40に向かって第1エアα1が吸引されることで、前記供給された粒状体3は前記キャリアウエブ1上に吸着保持される。
なお、第1エアα1の少なくとも一部にキャリアウエブ1の前記第2面12に沿う方向の流れの成分を付与する気流偏向体がキャリアウエブ1の第2面12に対向して設けられてもよい。(PCT/JP2012/52371)
粒状体3の層の厚さはアンビルロール4の軸方向において中央が両端よりも厚くてもよい。また、粒状体3の層の厚さは、1つの吸収性本体200(図1)の周縁において薄く、かつ、中央やその近傍において厚くてもよい。
一方、前記第1エアα1の吸引を行いながら、前記搬送面41の前記突部44Bおよび45を含む非吸引エリア4Aにおいて開口する吐出孔42から前記キャリアウエブ1の第2面12に向って第2エアα2が吐出される。
すなわち、前記非吸引エリア1Aにおける一部の粒状体3は前記吸引エリア1Bにおいて吸引保持されている別の粒状体3に向って移動する。その結果、図1に示すように、所定のパターンで互いに区画された前記配置エリアDごとに、複数の粒状体3からなる各集合グループ30がキャリアウエブ1上に配置される。
前述のように、図8の粒状体3はキャリアウエブ1上の前記吸引エリア1Bに集まり、当該吸引エリア1B以外の非吸引エリア1Aには残留しにくいだろう。しかし、粒状体3の質量は小さく、そのため、粒状体3の配置制御は難しく、したがって、図8の左側の突部44Bや図9Aの突部44B(45)の近傍に残留する場合がある。
また、不織布の微細な凹凸等により前記粒状体3が前記非吸引エリア1Aから前記吸引エリア1Bに移動する途中で不織布に引っかかり前記突部44B(45)の近傍に残留する場合がある。
たとえば、接合部は低強度接合部又は高強度接合部のうちの一方のみが設けられていてもよい。また、吐出孔は設けなくてもよい。
また、本発明における「複数の粒状体」とは、粒状の材料の集合体のみからなる場合の他に、複数の粒状体に粉状の材料が混合されている場合も含む概念である。
したがって、そのような変更および修正は、請求の範囲から定まる本発明の範囲内のものと解釈される。
