【発明の属する技術分野】
本発明は、フィルムや磁気テープ等の粘着面を有しない帯状体又は基材に積層された粘着剤層上に離型紙を貼付することにより両面を非粘着とした帯状体の巻取り方法及び装置に関し、巻始め及び巻終わりを自動的かつ効率的にできる巻取り方法及び巻取り装置、並びに当該巻取り方法で好適に用いられる巻始め及び巻終わり固定用テープに関する。
【０００２】
【従来の技術】
粘着面を有する粘着テープを商品用の小巻物にするための巻取り作業は、幅広で長大なテープを巻回してなる原反ロールから供給されるテープの先端を押圧用ロールで巻芯に押圧しながら巻取り、所定量巻取った後、カッターでテープの幅方向に切断し、巻取り終端となる切断端を押圧用ロールで押圧しつつ巻芯に巻き取ることにより行っている。そして、原反ロールの新たな先端となった部分を巻取り開始端として、待機させていた次の巻芯に押しつけ、同様にして巻取りを行う。このように、粘着テープの巻取り作業については、巻始めから巻終わりまでの一連の工程が連続自動化されている。
【０００３】
尚、商品用の小巻物は、幅広のテープを巻回してなる原反ロールから生産される円筒状巻回体を、巻芯の軸方向に垂直に所定長さ毎に切断することにより、あるいは原反ロールから供給される幅広テープを小巻用の細幅に切断し、細幅の巻芯に巻取って直接商品用の巻回体とすることにより製造されている。
【０００４】
一方、フィルムや磁気テープ等の粘着面を有しない帯状体や、片面粘着テープであっても粘着面に離型紙が貼付されて非粘着とされている帯状体の場合には、巻始めにおける巻芯への固定、さらには巻終わり時のテープ切断端の巻回体への固定については、別途粘着テープ等を用いて行う必要がある。このように粘着面を有しない帯状体の開始端及び終端の巻芯への貼付固定作業は、帯状体の巻取り作業を一旦停止して行わなければならないため、粘着テープと同程度に生産性を高めるためには、巻始め及び巻終わりの作業を、いかに効率よく行うかが重要なポイントとなる。
【０００５】
非粘着帯状体の巻取り開始及び巻取り終了を自動的に行う巻取り装置としては、一般に、所定長さに切断してなる両面粘着テープ片を吸着ブロック等で吸着しながら巻芯の所定位置にまで移動させ、巻き取ろうとするテープ先端とともに、巻芯の外周面に貼着させている。また、巻終わり時については、所定長さの両面粘着テープ片を吸着機構や把持手段を用いて移送し、巻終わり端に貼付固定させることにより行っている。
【０００６】
しかし、フィルムやテープのような薄いシート状物で、原反ロール幅と同じ幅広の粘着テープ片をたるみやシワ等を生じさせることなく、移送貼着させることは容易ではない。このため、一般に、小巻物の商品用テープの幅に該当する幅のロール（小巻用原反ロール）を一旦作製し、これを用いて、最終商品用の巻芯に巻き替えるということが行われていた。しかし、小巻用原反ロールを作製することは生産性向上の足かせとなるので、粘着テープの製造のように、原反ロールから、直接、最終商品用の小巻物を製造する方法が種々提案されている。
【０００７】
例えば、特許文献１には、巻芯の表面全体又は一部に粘着剤を塗布し、巻芯表面に形成された粘着剤層に帯状体の端部を仮止めして、テープの巻取り作業を始める巻取り方法が提案されている。しかし、この方法では、帯状体の終端を巻回体の最外周面に固定することができず、巻終わり作業については、粘着テープによる貼付固定作業及びそのための装置が必要となる。
【０００８】
特許文献２には、巻始め及び巻終りの双方を自動化する装置として、両面粘着テープ定寸貼着ユニットで所定長さに切断した両面粘着テープを、巻取り作業を行う帯状体の始端部に貼着し、両面粘着テープが貼着された帯状体の始端をグリップして、巻芯の周面に圧着固定する帯状体引出・巻付ユニットを具備した自動巻取り装置が提案されている。
【０００９】
また、特許文献３には、巻取り位置の巻芯に対して接近離間可能な揺動アームを用いて、所定長さに切断した粘着テープ片を、巻付けようとする帯状体の先端外周面から巻芯の外周面にかけて貼着させる巻取り装置が開示されている。
【００１０】
上記いずれの方法においても、粘着テープ片を正確に所定位置にまで移動させる高精度の制御機構を備えた移送手段を要する。
【００１１】
また、近年、巻回体をシュリンクフィルム等で包装する代わりに、巻回体の巻き終端に胴巻き用のフィルムを接合し、この胴巻き用フィルムで最外周を１周以上巻付けたものが簡易包装品として上市されている。このような簡易包装品では、単に帯状体の巻終わり端に粘着テープを貼着固定するだけではなく、巻取っている帯状体とは別に胴巻用フィルムをさらに巻付ける必要がある。この場合、原反ロールと同幅で且つ製品巻回体の一巻き分の長さを有する胴巻用フィルムをシワやたるみを生じさせることなく、目的位置へ移動させる必要があるが、前記文献に開示されているような移送手段では大がかりになりすぎて適用できない。
【００１２】
異なるフィルムを接合し、連続的に巻取り作業を行う方法及び装置としては、例えば、特許文献４に、最内周にエンドテープ、最外周にリーダーテープが接続されたリボンテープを紙管に自動的に巻取る方法が開示されている。開示されている方法は、まず、リーダテープの供給ロールから巻芯へ所定量巻取った後、リーダーテープを切断し、その切断端をリボンテープ供給ロール原反から引出されたリボンテープ先端と接合し、リボンテープを所定量巻取った後、リボンテープ終端をエンドテープ供給ロール原反から引出された先端に接合して巻取る方法であって、各テープへの接合は、テープの切断端を吸着ブロックに吸着させ、この吸着ブロックを、次に接合しようとするテープ端部の引出し位置にまで移動手段を用いて移動させ、接合後、紙管位置にまでガイドローラでガイドするというものである。

【発明が解決しようとする課題】
本発明は、上記事情に鑑みてなされたものであり、その目的とするところは、大がかりで且つ高精度な移送手段や把持手段等を必要とすることがなく、巻始め、巻終わりを自動的に行うことができ、しかも各種幅の商品巻回体に対応して、幅広の原反ロールから直接小巻物の商品巻回体を製造することができる巻取り方法及び装置、並びに当該方法で好適に用いられる巻始め及び巻終わり固定用テープを提供することにある。
【００１５】
【課題を解決するための手段】
本発明の帯状体の巻取り方法は、原反ロールから供給される帯状体を巻芯に巻取る方法であって、原反ロールから第１の巻芯まで供給された帯状体を、該原反ロールと該第１の巻芯との間で該帯状体の幅方向に切断し、該帯状体を切断部から原反ロール側と巻芯側に所定距離離間させる工程；原反ロール側切断端と巻芯側切断端とを、巻終り固定用粘着部と巻始め固定用粘着部を有する架設用テープで、巻終り固定用粘着部が巻芯側、巻始め固定用粘着部が原反ロール側となるように架設して、該架設用テープの介在により再び原反ロールから巻芯までが一体となった帯状体（以下「架設用テープ介在帯状体」という）とする工程；前記架設用テープ介在帯状体を、第１の巻芯に、架設用テープ部分の近傍まで巻取る工程；前記架設用テープ部分を、巻終わり固定用粘着部と巻始め固定用粘着部との間で切断した後、巻終わり固定用粘着部まで第１の巻芯に巻取る工程；及び巻始め固定用粘着部に、第２の巻芯をセットする工程を含む。
【００１６】
前記架設用テープは、原反ロール側端部及び巻芯側端部それぞれに、前記帯状体の切断端と略平行な筋状粘着部が設けられていて、該架設用テープの原反ロール側粘着部を前記帯状体の原反ロール側切断端に貼着し、該架設用テープの巻芯側粘着部を前記帯状体の巻芯側切断端に貼着することにより架設することが好ましく、また前記架設用テープは、架設用テープロールから前記帯状体の幅方向に供給され、架設後、該帯状体の幅に該当する長さ分が切り取られることが好ましい。
【００１７】
原反ロールから供給された帯状体は、帯状体の長手方向に往復動可能な一対の吸着ブロックで吸着した後切断され、前記一対の吸着ブロックを該帯状体の長手方向に所定距離離間するように移動させることにより、前記帯状体の切断部が巻芯側と原反ロール側に離間させられることが好ましい。
【００１８】
前記第１の巻芯としては、所定幅の巻芯を複数個、帯状体の幅方向に並設することにより、前記架設用テープ介在帯状体を長手方向に所定幅づつ切断しながら、個々の巻芯に巻取って行くことができる。
【００１９】
本発明の巻取り方法は、粘着面を有しない帯状体又は基材に積層された粘着剤層上に離型紙が貼付されて非粘着とされている帯状体の巻取りに適していて、特に布基材の片面に粘着剤層が設けられ、該粘着剤層上に離型紙が貼付された帯状体の巻取りに好適である。
【００２０】
本発明の巻始め及び巻終わり固定用テープは、原反ロールから巻芯に非粘着帯状体を巻取る際に、非粘着帯状体の先端を巻芯に貼付固定又は巻取りにより作製された帯状体の巻回体に帯状体の終端を貼付固定するために用いるテープであって、該テープの長手方向両側縁に沿って、前記非粘着帯状体に貼着するための架設用粘着部が配設されていて、前記架設用粘着部間に、巻始め固定用粘着部及び巻終り固定用粘着部が該テープの長手方向に沿って配設されている。
【００２１】
前記巻始め固定用粘着部と巻終り固定用粘着部との間には、粘着剤が塗工されていない口取り部が設けられていてもよいし、前記巻終り固定用粘着部と架設用粘着部との間は、粘着剤が塗工されていない巻回体胴巻き部が設けられていてもよい。あるいはテープの片面は両縁に設けられた架設用粘着部が連続一体化してなる粘着剤層となっていて、該粘着剤層の幅方向の所定位置に口取り部となる非粘着材が長手方向に沿って貼付されることにより、前記巻始め固定用粘着部と巻終わり固定用粘着部が形成されていてもよいし、該粘着剤層において、巻終わり側縁に架設用粘着部を残すように長手方向に沿って非粘着材が貼付されていて、該非粘着材が該架設用粘着部と前記巻終わり固定用粘着部との間に介在する胴巻き部となっていてもよい。
【００２２】
前記胴巻き部の長さは、前記巻終わり固定用粘着部が巻回体の外周面に巻取られた固定用テープの背面に貼着できるように、該巻回体の外周長さよりも長いことが好ましい。また前記巻回体胴巻き部及び／又は前記巻終わり固定用粘着部に文字、図柄等が印刷されていてもよい。
【００２３】
本発明の帯状体の巻取り装置は、原反ロールから帯状体を供給する帯状体供給ユニット；供給された帯状体を巻芯に巻取るために巻芯を軸支する巻芯支持部と、該巻芯を回転させる回転駆動部と、所定量巻取った帯状体を所定位置で切断するための第１の切断手段とを具備する巻取りユニット；前記帯状体供給ユニットと前記巻取りユニットとの間に設置され、帯状体を幅方向に分離切断する第２の切断手段と、帯状体切断端を原反ロール側と巻芯側に離間させる離間手段とを有する切断離間ユニット；及び前記離間された２つの切断端を、架設用テープで架設する架設ユニットを有する。
【００２４】
前記切断離間ユニットは、該帯状体の長手方向に往復動可能な一対の吸着ブロックを有していることが好ましく、前記架設ユニットは、架設用テープロールを、帯状体の幅方向に移送させる移送手段と、架設用テープの両側縁を帯状体に圧着させる圧着手段とを有していることが好ましく、前記第２の切断手段は、帯状体の幅方向に走行するカッターであることが好ましい。そして、このような圧着手段と第２の切断手段とは連結されていて、前記圧着手段が架設用テープを帯状体に圧着させるように下降したときは、前記第２の切断手段を該帯状体の上方に上昇させ、前記圧着手段が架設用テープの圧着を解除したときには、第２の切断手段を帯状体に接触するように下降させる制御機構を備えていてもよい。
【００２５】
前記巻取りユニットは、帯状体の巻取りを行っている第１の巻芯を軸支する第１の巻芯支持部と；第２の巻芯を軸支する第２の巻芯支持部と；該第１の巻芯及び第２の巻芯を適宜帯状体上にセットするように第１の巻芯支持部及び第２の巻芯支持部を移動させる移動機構とを備えていることが好ましい。この場合、第１の切断手段は、前記第１の巻芯と第２の巻芯との間に敷設された帯状体を切断するように設置されていることが好ましい。
【００２６】
【発明の実施の形態】
はじめに、本発明の巻始め及び巻終わりの固定用テープについて、図１に基づいて説明する。
【００２７】
本発明の固定用テープ１は、巻取る帯状体に貼着される架設用粘着部２ａ，２ｂが、該テープ１の長手方向両側縁に沿って設けられており、この架設用粘着部２ａ，２ｂの間に、巻取る帯状体の巻始め及び巻終わりをそれぞれ固定する巻始め固定用粘着部３及び巻終り固定用粘着部４となる筋状の粘着部が長手方向に沿って２本塗工されている。図１の固定用テープでは、巻始め固定用粘着部３と一側縁部の架設用粘着部２ｂとが隙間無く隣接しているため、合計３本の粘着部が塗工されたようになっている。
【００２８】
巻始め固定用粘着部３と巻終わり固定用粘着部４との間の粘着剤が塗工されていない部分は、最終商品たる小巻物巻回体の口取り部５となる部分であり、巻終り粘着部４と架設用粘着部２ａとの間の粘着剤が塗工されていない部分は、巻回体胴巻き部６となる部分である。胴巻き部６の幅Ｗは帯状体の巻回体の外周よりもやや長いことが好ましい。これにより巻回体を一巻き胴巻して、巻終わり粘着部４が固定用テープの背面、すなわち固定用テープの基材フィルム自体に自着することができ、巻回体を構成する帯状体の種類にかかわらず、所期の粘着力で巻終り端を固定できる。
【００２９】
尚、図１に示す固定用テープでは、架設用粘着部２ａ，２ｂ、巻始め固定用粘着部３、巻終わり固定用粘着部４をそれぞれ筋状に配設することにより口取り部５及び胴巻き部６が形成されていたが、固定用テープの片面全面に粘着剤が塗工されていて、口取り部及び胴巻き部に該当する部分に非粘着材たるフィルムを貼付して粘着部分を相殺することによって口取り部及び胴巻き部を形成するようにしてもよい。
【００３０】
また、図１に示す固定用テープは、架設用粘着部と、巻始め固定用粘着部及び巻終り固定用粘着部とが同一面に形成され、さらに粘着剤部が内周面となるように巻回された原反ロールであったが、本発明で用いられる固定用テープはこれに限定されない。例えば、架設用粘着部が形成された面の反対側面に巻始め固定用粘着部及び巻終り固定用粘着部が形成されていてもよいし、この場合、固定用テープロールは、架設用粘着部が外周側（又は内周側）になり、巻始め固定用粘着部及び巻終り固定用粘着部が内周側（又は外周側）となるように巻回されていてもよい。また、図１の固定用テープ１では、架設用粘着部２ｂと巻始め固定用粘着部３とが隙間無く隣接していたが、両者の間に隙間があってもよい。
【００３１】
次に、上記本発明の固定用テープ及び本発明の巻取り方法を用いて製造される最終製品の巻回体について、図２に基づいて説明する。
図２（ａ）は巻回体の最外周を所定長さに切断された固定用テープ片１’で巻回する前の状態を示しており、図２（ｂ）は市場に出回る最終製品の巻回体状態を示している。
【００３２】
この巻回体は、巻芯たる紙管７に帯状体８が所定量巻取られていて、帯状体８の終端に貼着固定された固定用テープ片１’が最外周面を１周巻回し、固定用テープ片１’の背面（外周面側）に巻終わり固定用粘着部４が貼着して巻回体の状態を保持している。固定用テープ片１’の先端は口取り部５となっていて、巻回体を胴巻きしている固定用テープ片１’を剥がしやすくなっている。
【００３３】
このような巻回体は、最外周面が固定用テープで胴巻されて巻回体の状態が保持されているので、シュリンクフィルム等で巻回体を包装しなくても、そのまま製品として市場に供給することができる。また、巻終わり固定用粘着部４に商品名や説明書等の文字、ロゴ等の図形又は図柄が印刷されていてもよいし、帯状体終端と固定用テープを接合している架設用粘着部２ａと、巻終わり固定用粘着部４との間の胴巻き部６に文字、図形等を印刷していてもよい。
【００３４】
また、胴巻き部が粘着部分を相殺するために貼付したフィルムにより形成されている固定用テープの場合には、当該フィルムの貼付面に文字、図形等を印刷してもよい。この場合、胴巻き部となるフィルムを換えるだけで胴巻き部の印刷内容を変更することができるので、多品種少量生産の対応に適している。
【００３５】
上記巻回体において巻芯７の種類は限定されず、紙管の他、塩化ビニル樹脂等の合成樹脂製又は金属製の巻芯であってもよく、最終製品の種類に応じて適宜選択される。
【００３６】
本発明の方法が適用される帯状体は、粘着面を有しない帯状体又は基材に積層された粘着剤層上に離型紙を貼付した帯状体であり、帯状体基材の材質は、プラスチックフィルムだけでなく、布を基材とするものであってもよい。特に本発明の方法は、布基材の片面に粘着剤が塗工され、粘着面に離型紙が貼付されて非粘着とされた帯状体を布基材が外周となるように巻取る場合に適しているからである。すなわち布基材を主体とする帯状体の巻回体を、固定用テープで最外周を胴巻きした巻回体では、粘着部が粘着する相手材は必ず固定用テープ基材のフィルムであるため、帯状体の材質、種類を考慮することなく、一定の粘着力で、一定の固定保持力を確保することができ、包装の役割を十分果たすことができるからである。この点、従来のように、端に巻終わり端を粘着テープで貼着しようとすると、織目等により粗面となっている布基材に対して巻回体を保持固定するだけの粘着力を発揮させることは困難であり、粘着力を高くしすぎると布表面に粘着剤が残ってしまうからである。
【００３７】
次に、本発明の方法を実施する巻取り装置の一実施形態について、図３に基づいて説明する。
図３は、本発明の帯状体巻取り装置の構成を示す概要図であり、帯状体の原反ロール１１から、帯状体１２を引出し供給する帯状体供給ユニット１０；供給された帯状体１２を巻芯２１ａに巻取る巻取りユニット２０；帯状体供給ユニット１０と巻取りユニット２０との間に配置され、帯状体１２を幅方向に切断し、該切断部にて所定距離離間する切断離間ユニット３０；及び離間された帯状体を架設する架設ユニット４０からなる。
【００３８】
帯状体供給ユニット１０は、原反ロール１１が軸支され、回転駆動部（図示せず）により回転させられて、帯状体１２を供給するようになっている。回転駆動部は、原反ロール１１の軸を直接回転するように取付けられていてもよいし、原反ロール１の外周面に接触して回転させる引出し回転用ロール（図示せず）に取付けられていてもよいし、原反ロール１１から帯状体１２を引出させる引出用ロール（図示せず）に取付けられてもよい。
【００３９】
尚、帯状体１２として、帯状体基材に粘着剤層が積層され、更に離型紙が貼付されているような複合タイプの帯状体を用いる場合には、上記帯状体供給ユニット１０は予め形成された複合タイプ帯状体を巻回してなる原反ロールを用いる場合に限定されず、帯状体基材の原反ロール及び離型紙の原反ロールを備え、さらに粘着剤塗工手段、乾燥手段等を具備して複合タイプ帯状体を形成しながら供給する構成としてもよい。
【００４０】
図４は、切断離間ユニット３０及び架設ユニット４０部分の拡大斜視図である。
切断離間ユニット３０は、帯状体供給ユニット１０と巻取りユニット２０との間を供給される帯状体１２の下方に設置された一対の吸着ブロック３１ａ，３１ｂと帯状体１２を幅方向に切断する切断手段たる丸刃３２を備えている。
【００４１】
吸着ブロック３１ａ，３１ｂは、帯状体１２の幅に該当する長さを有する角柱体で帯状体１２に面している側の面に吸着口が開設されていて、ブロック内を負圧にすると吸着口に帯状体１２を吸着固定できるようになっている。また、帯状体１２の長手方向に並設された２個の吸着ブロック３１ａ，３１ｂのうち、少なくとも一方が帯状体１２の長手方向に往復動できるように設置されている。従って、往復動できる吸着ブロック３１ａ，３１ｂの一方が移動することにより、あるいは２つの吸着ブロック３１ａ，３１ｂがそれぞれ反対方向に移動することによって一対の吸着ブロック３１ａ，３１ｂが離間したり、離間した吸着ブロック３１ａ，３１ｂが再度隣接するように近づいたりすることができる。
【００４２】
丸刃３２は、エアシリンダ３３に連結されていて、帯状体１２に接触するように下降したり、帯状体１２の上方に上昇できるようになっている。また、丸刃３２は、吸着ブロック３１ａ，３１ｂの境界線上を往復動させる移送機構（図示せず）に連結されていて、静置状態では、帯状体２の側縁の外側に待機するように配置され、作動状態のときには当該移送機構により、一対の吸着ブロック３１ａ，３１ｂの境界線上を走行して帯状体１２を切断するようになっている。
【００４３】
尚、切断離間ユニット３０に備えられる切断手段（特許請求の範囲にいう「第２の切断手段」に該当）は、本実施形態の丸刃３２に限定されず、帯状体を幅方向に切断できるものであればよく、例えば幅方向長さの刃を、一対の吸着ブロックの境界線上に配設して、必要に応じて上下動させることにより切断するようにしてもよい。
【００４４】
架設ユニット４０には、取付けた架設用テープロール４１を帯状体１２の幅方向に横断するように移送する移送手段（図示せず）と、架設用テープロール４１から架設用テープを引出して架設用テープの両側縁を帯状体に圧着できる圧着手段４２とを具備している。圧着手段４２は圧着用ボール４３と該圧着用ボール４３を上下動させるエアシリンダ４４とからなっている。移送手段としては、例えば、帯状体１２の両側端を架橋するように設けられた２本のガイドレールなどが挙げられ、架設用テープロール４１を軸支する軸を該ガイドレールに沿って搬送されるようにすればよい。
【００４５】
尚、圧着手段４２を構成する押え部材は架設用テープの両側縁に取付けられた圧着用ボール４３に限定されず、架設用テープの幅より大きい長さを有する丸棒を架設用テープを横断するようにセットして、該丸棒の、架設用テープの両側縁に当たる部分をエアシリンダ４４で押圧するようにしてもよい。また、圧着手段４２は、架設用テープロール４１の引出し端が架設時以外には自重で垂れないように吸着保持したり、必要に応じて先端を引出すような架設テープ用吸着部材を備えていてもよい。
【００４６】
図３及び図４に示す巻取り装置では、架設用テープロール４１の移送手段と丸刃３２の移送機構は共通の駆動部に接続されている。また圧着用ボール４３を上下動させるエアシリンダ４４と丸刃３２を上下動させるエアシリンダ３３は、共通の昇降駆動制御部（図示せず）に接続されていて、両者が相対するように上下動を行うことができるように連結されている。すなわち、丸刃３２が帯状体１２と接触するように下降位置にあるときには圧着用ボール４３が帯状体１２よりも上方に位置し、圧着用ボール４３が架設用テープを帯状体１２に圧着するように押圧しているときは、丸刃３２が帯状体１２よりも上方に上昇させられるようになっている。
【００４７】
尚、本発明の巻取り装置においては、切断離間ユニット３０の切断手段（特許請求範囲に記載の「第２の切断手段」）と架設ユニット４０とは連結していなくてもよく、該切断手段と架設ユニット４０が独立して作動するものであってもよい。
【００４８】
巻取りユニット２０は、帯状体１２が巻取られる巻芯２１ａを軸支する巻芯支持部２２と、帯状体を巻芯側へ押圧しつつ巻芯を回転させる巻芯回転駆動部とを備えている。
【００４９】
図３に示す巻取りユニット２０では、巻取り作業が行われている第１の巻芯２１ａの他に、次の巻取り作業を待機している第２の巻芯２１ｂ、さらには次の巻取り作業を待機している巻芯２１ｃ，２１ｄが各巻芯支持部２２ａ，２２ｂ，２２ｃ，２２ｄに支持されている。各巻芯支持部２２ａ，２２ｂ，２２ｃ，２２ｄは、９０°づつ間欠回転させる駆動部に直結された軸２３を中心として十字状に配設されている。そして第２の巻芯２１ｂを支持する巻芯支持部２２ｂが、第１の巻芯２１ａを支持する巻芯支持部２２ａよりも上流側に位置するように配置されていて、第１の巻芯２１ａの巻取り作業が終わると、軸２３を９０°回転して、待機している第２の巻芯２１ｂを巻取り位置に移動させるようになっている。
【００５０】
巻取りユニット２０において、巻取り作業を行っている第１の巻芯２１ａを回転駆動する巻取り用ロール２４が第１の巻芯２１ａに接する位置に取付けられ、次の巻取り作業を待機している第２の巻芯２１ｂを帯状体に押圧する押圧用ロール２５が巻取り用ロール２４よりも上流側に設置されている。この押圧用ロール２５は、帯状体に対して鉛直方向（矢印方向）に揺動できるようになっていて、巻取り終了時に第２の巻芯２１ｂに帯状体を押しつけて貼付固定することができる。
【００５１】
また、巻取りユニット２０は、所定量巻取った帯状体を所定位置で切断するための切断手段（特許請求の範囲の「第１の切断手段」に該当）２６を備えていて、図３に示す装置においては、この切断手段２６は、第１の巻芯２１ａと第２の巻芯２１ｂとの間に敷設される帯状体を切断できる位置に取付けられている。
【００５２】
尚、本発明の巻取り装置において、巻取りユニット２０は上記構成に限定されない。巻芯支持部は、少なくとも巻取り作業を行っている巻芯を支持できるものであればよく、巻取り作業の効率化のために、待機用の第２の巻芯、さらにはその後に続く巻取り作業を待機する巻芯を１個ないし数個を支持できるものであってもよい。また、待機している第２の巻芯をセットする機構は、回転によるものに限定されない。第１の巻芯による巻取り作業を行っている間に第２の巻芯を軸支させ、第１の巻芯による巻取り作業が終了するときに、第２の巻芯を軸支している軸を、所定位置に手動でセットすることもできる。
【００５３】
本発明の巻取り装置には、上記供給ユニット１０、巻取りユニット２０の間に、適宜必要に応じて、帯状体を供給するための供給ロールが取付けられる。図３に示す装置では、供給ユニット１０と切断分離ユニット３０との間に一対の供給用ロール１３ａ，１３ｂが配設され、切断分離ユニット３０と巻取りユニット２０との間に一対の供給用ロール１４ａ，１４ｂが配設されている。
【００５４】
次に、本発明の巻取り方法について、図３に示す装置及び図４に示す固定用テープ１を架設用テープとして用いた場合について説明する。
供給ユニット１０に取付けられた帯状体の原反ロール１１から引出された帯状体１２が、巻取りユニット２０まで連続している。巻回体１個分の長さが巻芯２１ａに向けて供給されたら、吸着ブロック３１ａ，３１ｂ内を負圧にして、吸着ブロック上面に敷設されている帯状体１２を吸着させる（図５（ａ）、図６（ａ））。次に、帯状体１２の側縁外側に待機させてていた丸刃３２を帯状体１２にまで下降させ、吸着ブロック３１ａ，３１ｂの境界線に沿って移動させて（図５（ｂ）、図６（ｂ））、帯状体１２を幅方向に切断する（図５（ｃ））。図５（ｃ）中、１５は切断部である。丸刃３２の移動に伴い共通の移動機構に取付けられた架設用テープロール４１も帯状体１２の上方で移動することになるが、図６の態様では架設テープ用吸着部材４５が架設用テープの先端を吸着して自重で垂れ下がらないようにしている。
【００５５】
切断が終了したら、吸着ブロック３１ａ，３１ｂを帯状体の長手方向に移動させて切断部１５から巻芯側と原反ロール側とに離間させる。これにより、切断された帯状体が切断部から、巻芯側帯状体１２ａと原反ロール側帯状体１２ｂとに分断されることになる（図５（ｄ））。ここで、吸着ブロック３１ａ，３１ｂ間の離間距離Ｌ_１は、最終製品たる巻回体の種類により決まり、具体的には、架設用テープとして用いられる架設用粘着部２ａ，２ｂの内縁側間距離Ｌ_２（図１参照）よりも短いことが好ましい。また、一対の吸着ブロック３１ａ，３１ｂは、双方の吸着ブロックが反対方向に移動することにより離間してもよいし、一方の吸着ブロックだけが移動することにより離間してもよい。
【００５６】
次に、丸刃３２を上昇させ、架設ユニット４０のエアシリンダ４４で圧着用ボール４３を下降させて、架設用テープ先端を帯状体に接触させる（図６（ｃ））。そして、架設テープ用吸着部材４５による吸着を解除し、圧着用ボール４３で、架設用テープ両側縁の架設用粘着部５１ａ，５１ｂをそれぞれ巻芯側切断部及び原反ロール側切断部に圧着させつつ、架設用テープロール４１を帯状体の幅方向に移動させる（図６（ｄ））。離間された帯状体の間に、架設用テープで架設した後、帯状体側縁の外側に待機させていた切断カッター４６で架設用テープを切断する。図５（ｅ）は、架設用テープ５１により巻芯側帯状体１２ａと原反ロール側帯状体１２ｂとが架設されて、再び原反ロールから巻芯まで連続した一体物の帯状体（架設用テープ介在帯状体）となった状態を示している。架設後、架設用テープロール４１及びこれに連結されている丸刃３２が帯状体側縁外側の元の待機位置に戻る。
【００５７】
ここで、図６の場合には、架設用テープの外周面が帯状体に貼着されることになるが、架設用テープロール４１として、架設用粘着部が内周面となるように巻回されたロールを用いた場合には、図７のように、架設用テープロール４１の先端が反転用ロール４７を介して圧着用ボール４３にまでガイドすれば、架設用テープロール４１の内周面が帯状体に接触できる。
【００５８】
また、上記架設ユニットでは圧着用ボールで架設用テープ先端を圧着させるものであったが、本発明の巻取り装置はこれに限定されず、例えば、架設用ロールを帯状体の切断部を跨ぐように転動しながら巻芯側切断部及び原反ロール側切断部と架設用テープの架設用粘着部とが架設用テープの自重により貼着するようにしてもよい。
【００５９】
架設終了後、吸着ブロック３１ａ，３１ｂの負圧を解除して、架設用テープ介在帯状体を吸着ブロックから脱着させ、巻取り装置の供給ロールを回転させて、架設用テープ介在帯状体を巻芯２１ａに巻取っていく。
【００６０】
図８は、巻取りユニット２０において、第１の巻芯２１ａに所定量帯状体が巻取られて、架設用テープ部分５１まで巻取られた状態を示している。架設用テープ５１の巻終り固定用粘着部５４及び巻始め固定用粘着部５３は、まだ巻取られていない。
【００６１】
かかる状態で、次の巻取りの巻芯となる第２の巻芯２１ｂを巻始め固定用粘着部５３に貼着固定するように、押圧用ロール２５を、第２の巻芯２１ｂに押圧する。次いで、第１の切断手段たるカッター２６が巻始め固定用粘着部５３と巻終わり固定用粘着部５４との間を切断する。巻取り用ロール２４が回転して架設用テープ５１の巻終わり固定用粘着部５４まで第１の巻芯２１ａに巻取られる。これにより、架設用粘着部５２ａと巻終わり固定用粘着部５４との間の胴巻部５６で１周胴巻きされ、且つ口取り部５５を先端とする巻回体が得られる。一方、切断後、巻芯支持部を９０°回転させて、第２の巻芯２１ｂを第１の巻芯位置、すなわち巻取り用ロール２４上に移送する。第２の巻芯２１ｂの移動により、第２の巻芯２１ｂに巻始め固定用粘着部５３が貼着固定された帯状体が巻取り用ロール２４の位置にまで搬送されることになり、これにより、帯状体が原反ロール１１から巻芯まで連続した初期の状態の戻る。尚、上記実施形態の方法では、第２の巻芯の移送を巻芯支持部の回転により行ったが、本発明の方法はこれに限定されず、例えば、搬送ガイド等で第２の巻芯を支持する巻芯支持部を巻取り位置に搬送してもよい。また、上記実施形態では、第２の巻芯のセット後架設用テープを切断したが、切断後又は切断と同時に第２の巻芯をセットしてもよい。
【００６２】
以上のような工程を繰り返すことにより、原反ロールからの巻取り作業において、巻始め、巻終わりを自動的に連続して行うことができる。得られた巻回体は、原反ロール幅の巻回体であるから、その後、所定幅に切断して、最終製品とすることができる。また、巻取り作業の間に所定幅に切断して最終製品の小巻物が直接製造されるようにしてもよい、例えば、図８のＡ位置、すなわち第１の巻芯２１ａ近傍に所定間隔毎にカッターを並設させて、カッターと接するように回転させて、所定幅毎に切断してもよい。また、図９のように、予め巻芯として、所定幅毎に切断された小巻用巻芯２１’ａを軸に隙間無く並設した巻芯群を用いて、図８におけるＢ位置、すなわち第１の巻芯の上流位置に所定間隔毎にカッター４９を並設させ、該カッター４９で細幅に切断された帯状体を個々の巻芯２１’ａに供給するようにしてもよい。また、所定間隔をおいて所定幅の小巻物用巻芯を並列させた巻芯群を２つ準備し、図８におけるＢ位置に並設させたカッターで所定幅に切断された細幅帯状体を、２つの巻芯群にそれぞれ供給されるようにしてもよい。
【００６３】
いずれの場合も、巻始め、巻終わりを連続して行うことができ、しかも巻始め及び巻終わり固定用テープを直接巻芯に貼着固定させることなく、帯状体として巻取ってしまうことができるので、幅広の原反ロールから、高精度な移動手段や把持手段を要することなく、直接小巻物の商品用巻回体を製造することができる。特に、固定用テープと帯状体との接合は、幅広な原反ロール幅の状態で行うことができるので、架設工程に要求される精度は、小さな巻芯に粘着テープ片を移動固定させるときに要求される精度程、厳しくない。従って、原反ロールに該当する幅を一辺とし、さらに巻回体の外周分よりも長い長さを一辺とする大サイズの胴巻部を有する固定用テープであっても、シワやたるみを生じさせることなく、架設用テープ介在帯状体を作製することができる。その上、本発明の装置によれば、外周サイズが異なる種々の巻回体を胴巻して巻終わりを固定する場合であっても、切断分離ユニットの吸着ブロックの移動距離を調節するだけでよい。この点、従来の巻取り方法によれば、大サイズのフィルムであれば、大がかりな移動機構を要する上に、移動させようとするフィルムサイズに応じたサイズの移動機構が必要となることに鑑みれば、本発明の方法及び装置は汎用性の点でも優れている。
【００６４】
尚、上記実施形態では、架設ユニットが帯状体の幅方向に横断するように移送する移送手段を備えた巻取り装置を用いて、架設用テープロールを帯状体の幅方向に供給して架設する方法であったが、本発明の方法はこれに限定しない。架設用テープロールが、例えば帯状体の上方に設置され、帯状体の長手方向に沿って架設用テープを供給し、離間された帯状体の原反ロール側切断端と巻芯側切断端を架設するようにしてもよい。この場合、巻始め固定用粘着部及び巻終わり固定用粘着部は架設用テープにおいて幅方向に延設されている必要があるため、長手方向に沿って粘着部が配設されている本発明の巻始め及び巻終わり固定用テープを利用することはできないが、例えば、片面全体に粘着剤が塗工された架設用テープを巻回してなる架設用テープロールを使用し、架設用テープの供給に際して口取り部及び／又は胴巻き部となる部分に非粘着材を貼付して架設、あるいは架設した後、口取り部及び／又は胴巻き部となる部分に非粘着材を貼付してもよい。
【００６５】
また、上記実施形態では、口取り部及び胴巻き部を有する固定用テープを架設用テープとして用いたが、本発明の巻取り方法はこれに限定されず、架設用粘着部、巻終わり固定用粘着部及び巻始め固定用粘着部の全てが一体化、すなわち片面が粘着剤層となっていて、口取り部や胴巻き部となる非粘着材も貼付されていないテープを架設用テープとして用いる場合にも適用できる。
【００６６】
【発明の効果】
本発明の巻取り方法及び巻取り装置によれば、巻始め及び巻終わり作業を巻取り作業中の一工程に組み入れてしまうことができ、巻取り作業を効率的に自動化でき、しかも帯状体の原反ロールから小巻物の製品を製造する場合にも高精度な機構、手段を要求せずに済む。
【００６７】
また、本発明の巻取り方法及び装置を用いれば、種々の巻回体のサイズに適用することが可能であり、胴巻き部及び口取り部のサイズが種々に異なる巻回体を１つの巻取り装置で対応することができ、汎用性がある。

BACKGROUND OF THE INVENTION
The present invention relates to a method and an apparatus for winding a belt-like body in which both surfaces are non-tacky by sticking a release paper on a belt-like body having no adhesive surface such as a film or a magnetic tape or an adhesive layer laminated on a substrate. In particular, the present invention relates to a winding method and a winding device that can automatically and efficiently perform winding start and winding end, and a winding start and winding end fixing tape that is preferably used in the winding method.
[0002]
[Prior art]
The winding work to make the adhesive tape with the adhesive surface into a small roll for products is to press the tip of the tape supplied from the raw roll made by winding a wide and long tape against the core with the pressing roll Then, after winding and winding a predetermined amount, it is cut by a cutter in the width direction of the tape, and the cut end that is the winding end is pressed by a pressing roll and wound around the core. And the part which became the new front-end | tip of an original fabric roll is made into a winding start end, it presses on the next core which was made to stand by, and it winds up similarly. As described above, with regard to the winding operation of the adhesive tape, a series of steps from the beginning of winding to the end of winding are continuously automated.
[0003]
In addition, a small roll for goods is obtained by cutting a cylindrical wound body produced from a raw roll formed by winding a wide tape at predetermined lengths perpendicular to the axial direction of the core, or It is manufactured by cutting a wide tape supplied from an original fabric roll into a narrow width for a small volume, winding it around a narrow width core and directly forming a wound body for a product.
[0004]
On the other hand, in the case of a strip that does not have an adhesive surface, such as a film or magnetic tape, or a strip that is non-adhesive even if it is a single-sided adhesive tape, a release paper is attached to the adhesive surface. The fixing to the core and the fixing of the tape cutting end at the end of winding to the wound body must be performed separately using an adhesive tape or the like. As described above, since the work for fixing the belt-like body having no adhesive surface to the start and end cores has to be performed after the belt-winding work has been temporarily stopped, it can be as productive as adhesive tape. In order to increase the efficiency, it is an important point how efficiently the work at the beginning and end of winding is performed.
[0005]
As a winding device for automatically starting and ending winding of a non-adhesive strip, generally a predetermined position of the core while adsorbing a double-sided adhesive tape piece cut to a predetermined length with an adsorption block or the like It is made to stick to the outer peripheral surface of a winding core with the tape front-end | tip which is moved to (1) and winds up. Further, at the end of winding, a double-sided adhesive tape piece having a predetermined length is transferred by using a suction mechanism or a gripping means, and is stuck and fixed to the end of winding.
[0006]
However, it is not easy to transfer and stick an adhesive tape piece having the same width as the original roll width without causing sagging or wrinkles with a thin sheet-like material such as a film or a tape. For this reason, in general, a roll having a width corresponding to the width of the product tape of the small roll (raw roll roll) is once prepared and used to rewind to the final product core. It was broken. However, since making a roll for small rolls is a drag on productivity, various methods for producing small rolls for final products directly from rolls like the production of adhesive tapes are proposed. Has been.
[0007]
For example, in Patent Document 1, an adhesive is applied to the entire surface or a part of the core, and the end of the strip is temporarily fixed to the adhesive layer formed on the surface of the core. A winding method for starting is proposed. However, in this method, the end of the belt-like body cannot be fixed to the outermost peripheral surface of the wound body, and for the winding end work, a sticking and fixing work using an adhesive tape and a device for that work are required.
[0008]
In Patent Document 2, as a device for automating both the beginning and end of winding, a double-sided adhesive tape cut to a predetermined length by a double-sided adhesive tape fixed-size sticking unit is attached to the starting end of a belt-like body that performs a winding operation. There has been proposed an automatic winding device provided with a belt-like body drawing / winding unit that is attached and grips the starting end of the belt-like body to which a double-sided adhesive tape is attached, and is crimped and fixed to the peripheral surface of the core.
[0009]
Further, Patent Document 3 discloses that the outer peripheral surface of the front end of a belt-like body on which an adhesive tape piece cut into a predetermined length is wound using a swing arm that can approach and separate from the winding core at the winding position. A winding device for sticking from the outer periphery of the core to the outer periphery of the core is disclosed.
[0010]
In any of the above methods, a transfer means having a highly accurate control mechanism for accurately moving the adhesive tape piece to a predetermined position is required.
[0011]
Also, in recent years, instead of wrapping a wound body with a shrink film or the like, a body wrapping film is joined to the winding end of the wound body, and the body wrapping film is wound around the outermost circumference one or more times for simple packaging. It is marketed as a product. In such a simple packaged product, it is necessary not only to simply stick and fix the adhesive tape to the winding end of the belt-like body, but also to wind the body-wound film separately from the belt-like body being wound. In this case, it is necessary to move the body winding film having the same width as the raw roll and the length of one turn of the product wound body to the target position without causing wrinkles or sagging. The transfer means as disclosed is too large to apply.
[0012]
As a method and apparatus for joining different films and continuously winding them up, for example, in Patent Document 4, a ribbon tape with an end tape connected to the innermost periphery and a leader tape connected to the outermost periphery is automatically applied to the paper tube. A method of automatically winding is disclosed. In the disclosed method, first, after winding a predetermined amount from the supply roll of the leader tape to the core, the leader tape is cut, and the cut end is joined to the leading end of the ribbon tape drawn out from the ribbon tape supply roll. In this method, after winding a predetermined amount of the ribbon tape, the ribbon tape end is joined to the leading end drawn from the end tape supply roll, and wound. The suction block is sucked, and the suction block is moved to the drawing position of the tape end to be joined next by using a moving means, and after joining, the guide roller is guided to the paper tube position. .

[0061]
In this state, the pressing roll 25 is pressed against the second core 21b so that the second core 21b serving as the core for the next winding is stuck and fixed to the winding start fixing adhesive portion 53. . Next, the cutter 26 as the first cutting means cuts between the winding start fixing adhesive portion 53 and the winding end fixing adhesive portion 54. The winding roll 24 rotates and is wound around the first core 21 a up to the winding end fixing adhesive portion 54 of the erection tape 51. As a result, a wound body is obtained in which the body is wound around the body winding portion 56 between the erection adhesive portion 52a and the winding end fixing adhesive portion 54, and the chamfered portion 55 is the tip. On the other hand, after cutting, the core support part is rotated by 90 °, and the second core 21 b is transferred onto the first core position, that is, on the winding roll 24. Due to the movement of the second core 21b, the belt-like body in which the winding start fixing adhesive portion 53 is stuck and fixed to the second core 21b is conveyed to the position of the winding roll 24. As a result, the initial state in which the belt-like body continues from the raw fabric roll 11 to the core is returned. In the method of the above-described embodiment, the second core is transferred by rotating the core support portion. However, the method of the present invention is not limited to this, and the second core is, for example, a conveyance guide or the like. The core support portion that supports the roller may be conveyed to the winding position. Moreover, in the said embodiment, although the tape for construction after setting of a 2nd core was cut | disconnected, you may set a 2nd core after cutting or simultaneously with a cutting | disconnection.
[0062]
By repeating the steps as described above, the winding start and the winding end can be automatically and continuously performed in the winding operation from the raw roll. Since the obtained wound body is a wound body having a raw roll width, it can be cut into a predetermined width to obtain a final product. Further, a small roll of the final product may be directly manufactured by cutting to a predetermined width during the winding operation. For example, at a predetermined interval at the position A in FIG. 8, that is, in the vicinity of the first core 21a. The cutters may be arranged side by side, rotated so as to be in contact with the cutter, and cut at predetermined widths. Further, as shown in FIG. 9, using a core group in which small cores 21 ′ a cut at predetermined widths as a core in advance are arranged side by side without a gap, the position B in FIG. 8, that is, The cutters 49 may be arranged in parallel at predetermined intervals at the upstream position of the first core, and the strips cut with the cutter 49 in a narrow width may be supplied to the individual cores 21'a. In addition, two narrow cores in which small roll cores having a predetermined width are arranged in parallel at a predetermined interval are prepared, and a narrow band-shaped body cut to a predetermined width by a cutter arranged in parallel at position B in FIG. May be supplied to each of the two core groups.
[0063]
In any case, the winding start and the winding end can be performed continuously, and the winding start and the winding end fixing tape can be wound up as a band without directly sticking and fixing to the core. Therefore, a product roll of a small roll can be directly manufactured from a wide raw roll without requiring highly accurate moving means and gripping means. In particular, the joining of the fixing tape and the belt-like body can be performed in a state of a wide raw roll width, so the accuracy required for the erection process is when the adhesive tape piece is moved and fixed to a small core. Not as strict as the required accuracy. Accordingly, even a fixing tape having a large-sized body winding portion having a width corresponding to the raw roll as one side and a length longer than the outer circumference of the wound body as one side causes wrinkles and sagging. It is possible to produce an erected tape-incorporating strip without any problems. Moreover, according to the apparatus of the present invention, even when various winding bodies having different outer peripheral sizes are wound around and the winding end is fixed, it is only necessary to adjust the moving distance of the suction block of the cutting / separating unit. . In this regard, according to the conventional winding method, in the case of a large-sized film, a large-scale moving mechanism is required, and a moving mechanism having a size corresponding to the size of the film to be moved is required. For example, the method and apparatus of the present invention are excellent in versatility.
[0064]
In the above embodiment, the erection tape roll is supplied in the width direction of the belt-like body and installed by using a winding device provided with transfer means for transporting the erection unit so as to cross in the width direction of the belt-like body. Although it is a method, the method of this invention is not limited to this. The erection tape roll is installed, for example, above the belt-like body, supplies the erection tape along the longitudinal direction of the belt-like body, and constructs the separated roll-side cut end and the core-side cut end of the separated belt-like body You may make it do. In this case, since the winding start fixing adhesive portion and the winding end fixing adhesive portion need to be extended in the width direction in the erection tape, the adhesive portion is disposed along the longitudinal direction. Although the winding start and end fixing tapes cannot be used, for example, when using a construction tape roll formed by winding a construction tape coated with an adhesive on one side, A non-adhesive material may be affixed to the part that becomes the mouthpiece and / or the body winding part, and the non-adhesive material may be affixed to the part that becomes the mouthpiece and / or the body winding part.
