- a widening step of widening a gap in the width direction between a pair of panels adjacent to each other in the flow direction among the plurality of panels;
- a first axis of a first roller that receives and holds one panel of the set of panels spaced apart from each other in the width direction, and a second axis that receives and holds the other panel of the set of panels.
- extending in the width direction orthogonal to the flow direction means including not only extending in the width direction but also extending in both the width direction and the flow direction.
- the manufacturing apparatus of the present invention is a manufacturing apparatus for disposable wearing articles in which a pair of panels are joined to each other at the same position in the longitudinal direction of the main body and on both the left and right sides in the waistline direction.
- a cutter that sequentially cuts the leading end portion of the continuous web in the flow direction along a virtual cutting line extending in the width direction orthogonal to the flow direction to generate a plurality of panels one after another;
- a widening drum that widens the gap in the width direction between a pair of panels adjacent to each other in the flow direction among the plurality of panels;
- a first axis of a first roller that receives and holds one panel of the set of panels spaced apart from each other in the width direction, and a second axis that receives and holds the other panel of the set of panels.
- the second axis of the roller is arranged to be offset from each other in the flow direction of the panel, and the first and second rollers receive the panels at first and second receiving positions spaced from each other along the flow direction. Furthermore, the phase wheel which arrange
- the first axis of the first roller and the second axis of the second roller are offset from each other by a predetermined offset amount ⁇ . Therefore, among the rollers, the first roller offset to the downstream side. Receives the panel from the widening drum at a position that is substantially equal to the offset amount ⁇ from the second roller.

- a phase wheel that is disposed downstream of the widening drum and that disposes each of the pair of panels on both sides of the main body.
- the panel before the panel cut from the continuous web is moved in the width direction, the panel is moved in the flow direction by the first re-pitch step, thereby increasing the interval between adjacent panels. Therefore, there is no possibility that the panels interfere with each other when the panels are moved in the width direction to widen the interval between the panels. Therefore, there is no possibility that the holding position of the panel is shifted or wrinkles due to interference between the panels.
- “extending in the width direction” may be set such that a virtual cutting line is set along a side perpendicular to the flow direction, or may be set in an oblique direction inclined with respect to the width direction. Furthermore, it means that a quadratic curve or a cubic curve may be used instead of a straight line. For example, even if a virtual cutting line is set along the side, the interval in the flow direction between the panels is expanded in advance by the first re-pitch process, so that the panels are expanded during the widening process. Are not likely to interfere with each other due to wind pressure or the like.

Description
流れ方向に連続する連続ウエブの前記流れ方向の先端部を前記流れ方向に直交する幅方向に延びる仮想の切断線に沿って次々に切断して複数のパネルを次々に生成する切断工程と、
前記複数のパネルのうちの前記流れ方向に互いに隣接する一組のパネル同士の前記幅方向の間隔を拡げる拡幅工程と、
前記幅方向に互いに離間された一組のパネルのうちの一方のパネルを受け取って保持する第1ローラの第1軸線と、前記一組のパネルのうちの他方のパネルを受け取って保持する第2ローラの第2軸線とが前記パネルの流れ方向に互いにオフセットして配置され、前記第1および第2ローラで前記流れ方向に互いに離間した第1および第2受取位置において前記各パネルを受け取る受取工程と、
前記第1および第2ローラから前記各パネルを前記流れ方向に互いに離間した第1および第2渡し位置において前記本体部の前記縦方向の互いに同じ位置において前記両サイドに配置する配置工程とを備える。
なお、「流れ方向に直交する幅方向に延びる」とは、幅方向にのみ延びる場合の他、幅方向および流れ方向の双方に延びる場合を含むことを意味する。
流れ方向に連続する連続ウエブの前記流れ方向の先端部を前記流れ方向に直交する幅方向に延びる仮想の切断線に沿って次々に切断して複数のパネルを次々に生成するカッターと、
前記複数のパネルのうちの前記流れ方向に互いに隣接する一組のパネル同士の前記幅方向の間隔を拡げる拡幅ドラムと、
前記幅方向に互いに離間された一組のパネルのうちの一方のパネルを受け取って保持する第1ローラの第1軸線と、前記一組のパネルのうちの他方のパネルを受け取って保持する第2ローラの第2軸線とが前記パネルの流れ方向に互いにオフセットして配置され、前記第1および第2ローラで前記流れ方向に沿って互いに離間した第1および第2受取位置において前記各パネルを受け取り、更に、前記第1および第2ローラから前記各パネルを前記流れ方向に互いに離間した第1および第2渡し位置において前記本体部の前記縦方向の互いに同じ位置において前記両サイドに配置する位相ホイールとを備える。
流れ方向に連続する連続ウエブの前記流れ方向の先端部を前記流れ方向に直交する幅方向に延びる仮想の切断線に沿って次々に切断して複数のパネルを次々に生成する切断工程と、
前記複数のパネル同士の前記流れ方向の間隔を拡げる第1リピッチ工程と、
前記第1リピッチ工程の後に、前記複数のパネルのうちの互いに隣り合う一組の前記パネル同士の前記幅方向の間隔を拡げる拡幅工程と、
前記拡幅工程の後に、前記一組のパネルの各々を前記本体部の前記両サイドに配置する配置工程とを備える。
流れ方向に連続する連続ウエブの前記流れ方向の先端部を前記流れ方向に直交する幅方向に延びる仮想の切断線に沿って次々に切断して複数のパネルを次々に生成するカッターと、
前記複数のパネル同士の前記流れ方向の間隔を拡げる第1リピッチドラムと、
前記第1リピッチドラムの下流に配置され、前記複数のパネルのうちの互いに隣り合う一組の前記パネル同士の前記幅方向の間隔を拡げる拡幅ドラムと、
前記拡幅ドラムの下流に配置され、前記一組のパネルの各々を前記本体部の前記両サイドに配置する位相ホイールとを備える。
たとえば、仮想の切断線が真横に沿って設定されている場合であっても、予め第1リピッチ工程により前記パネル同士の流れ方向の間隔が拡げてあることで、前記拡幅工程の際にパネル同士が風圧等により互いに干渉されるおそれがない。
この場合、サーボモータを用いた電気制御により、複数種類のサイズの着用物品を単一の製造装置で製造することができる。
「非平行」とは、仮想の切断線が流れ方向に直交する真横に沿って設定されている場合を除く概念である。すなわち、前記仮想の切断線が前記幅方向に対し傾いた斜め方向に設定されていてもよいし、更に、直線ではなく、二次曲線や三次曲線などであってもよいことを意味する。
前記受取工程の後に、前記組間隔を更に拡げる第3リピッチ工程を更に備える。
まず、本製造方法および装置の説明に先立って、本製造方法により製造が可能な着用物品の一例が説明される。
前記本体部20は、着用時に着用者の前胴回り域、股下域および後胴回り域を覆う。本体部20は当該各領域に対応する前胴部20f、股下部20cおよび後胴部20bを備えている。
なお、前記パネルPL,PRに弾性糸を配置する方法としてはJP63-243309Aに開示された方法が用いられてもよい。
また、前記パネルPL,PRは前記弾性糸を有しない伸縮性を有する伸縮性不織布で形成されていてもよい。
図3Aに示すように、本製造装置は、カッター1、アンビルロール2、第1リピッチドラム3、拡幅ドラム(第2リピッチドラム)4、位相ホイール5および搬送装置6を備える。
なお、前記第1リピッチドラム3はUS2006/0151093 A1やJP63-317576Aに開示されたドラムを用いることができ、ここに、その記述の全てが組み込まれる。
すなわち、拡幅ドラム4が周方向Rに回転しながら、右用パッド4Rが拡幅ドラム4の一方の側へ移動し、左用パッド4Lが拡幅ドラム4の他方の側へ移動することでパッド4Rと4Lとの幅方向Xの間隔が拡げられると共に、第2リピッチドラムを構成する同拡幅ドラム4により、流れ方向Yに隣り合うパッド4R,4R(4L,4L)同士の流れ方向Yの間隔が拡げられる(第2リピッチ工程)。第2リピッチ工程において、図1に示すように、流れ方向に隣り合うパネル同士PL,PL(PR,PR)の間隔は(2*P1)からP2へと拡げられる。
後述する配置工程においてパネルPR,PLをそれぞれ第1および第2ローラに51,52に渡した後、再びパネルPR,PLを受け取るために前記右用および左用パッド4R,4L間の幅の間隔は元の状態に戻り、かつ、リピッチされた同パッド間の流れ方向の間隔も元に戻る。
かかる拡幅ドラム4の構造としては、たとえばJP2006-230438 Aに開示されたドラムの構造が採用されてもよく、ここに、その記述の全てが組み込まれる。
図5の前記幅方向Xに互いに離間された一組のパネルPL,PRのうちの一方のパネルPRを受け取って保持する第1ローラ51の第1軸線51Sと、前記一組のパネルPL,PRのうちの他方のパネルPLを受け取って保持する第2ローラ52の第2軸線52Sとは、前記パネルPL,PRの流れ方向Yに互いにΔだけオフセット(偏心)して配置されている。
また、前記右用パネルPRと左用パネルPLとの間には位相差があるため、これらのパネルをそれぞれ下流において受け取る第1パッド51Pおよび第2パッド52Pは周方向の位置において互いにズレている。
本実施例の製造方法は、以下に説明する切断工程、第1リピッチ工程、拡幅工程、第2リピッチ工程、受取工程および配置工程を備える。
この際、一組のパネルPL,PRには図1のピッチP1の位相のズレ(位相差)が存在する。
図7Aに示すように、第1ローラ51から右用パネルPRが第1渡し位置P21において本体部20の一方の側に配置された後、流れ方向Yの下流において、図7Bに示すように第2ローラ52から左用パネルPLが第2渡し位置P22において本体部20の他方の側に配置される。
ここで、本発明の原理について、図9を用いて更に詳しく説明する。
図9に明示するように、第1受取位置P11と第2受取位置P12とのオフセット量C・Δは第1渡し位置P21と第2渡し位置P22とのオフセット量Δに比べ小さくなるだろう。したがって、正確には(P1=2*Δ)とはならないだろう。前記オフセット量C・Δと前記オフセット量Δとの差について、現場で調整して適当な値に設定する。
本実施例においては、複数種類の本体部20のサイズを一つの製造装置により、部品を取り換えることなく、製造し得るものである。
前記変速制御装置は、たとえばサーボモータを制御し、前記ローラ51,52が前記受け取りから前記配置までの間に前記パネルPL,PRを保持する複数のパッド51P,52Pの回転速度が着用物品のサイズに合わせて、1回転につき前記各パッド51P,52Pの数だけ周期的に変速される。たとえば、本体部20のサイズが標準よりも長い場合、前記位相ホイール5は前記拡幅ドラム4の下流に配置され、前記組間隔の拡がった複数組のパネルPL,PRを次々に受取り前記受取後に、前記組間隔をP2からP3に更に拡げる。
かかる周期的な変速の方法は、主モータと補助的なサーボモータを用いるが、たとえばJP2002-35027Aに開示されており、その記述の全てがここに組み込まれる。
たとえば、位相ホイール5を有していなくてもよい。
また、着用物品はオムツ型であっても、パンツ型であってもよい。
したがって、以上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。
