　本発明は、帯状物が巻き回されることによって製造される巻回体の製造方法および製造装置に関し、特に、伸縮性または／および吸液性に富んだ柔軟な帯状物が巻き回されることによって製造される巻回体の製造方法および製造装置に関する。 The present invention relates to a method and an apparatus for manufacturing a wound body that is manufactured by winding a strip, and in particular, a flexible strip having excellent stretchability and / or liquid absorption is wound. The manufacturing method and manufacturing apparatus of the wound body manufactured by this.
　従来、インクジェット塗布装置のノズル面に付着した余剰のインクを拭き取るためのクリーニング部材として、帯状物が巻き回されることによって製造された巻回体が使用されている。当該クリーニング部材にあっては、内部に吸液のための孔が多数形成されていることが必要であり、また拭き取りの際にノズル面に適度に弾性接触することが必要であるため、クリーニング部材としての巻回体を構成する帯状物としては、たとえばポリエステル製の編み物等に代表されるような伸縮性および吸液性に富んだ柔軟な帯状物が利用されている。 Conventionally, a wound body manufactured by winding a strip is used as a cleaning member for wiping off excess ink adhering to the nozzle surface of an ink jet coating apparatus. In the cleaning member, it is necessary that a large number of holes for absorbing liquid are formed in the inside, and it is necessary to make an appropriate elastic contact with the nozzle surface during wiping. As the belt-like material constituting the wound body, for example, a flexible belt-like material rich in stretchability and liquid-absorbing property such as polyester knitting is used.
　ここで、クリーニング部材としての巻回体においては、上述したように巻回後において適度な弾性を発揮することが必要であるため、帯状物の巻き回しの際には、当該帯状物が緩く巻き回されるように調整することが重要になる。当該観点から、従来においては、巻き回しの際に帯状物に実質的に張力がかからないように、手作業でこれを巻き回すことが行なわれていた。 Here, in the wound body as the cleaning member, it is necessary to exhibit appropriate elasticity after winding as described above. Therefore, when the belt is wound, the belt is loosely wound. It is important to adjust so that it is turned. From this point of view, conventionally, this has been performed by hand so that the belt is not substantially tensioned during winding.
　一方で、帯状物を機械を用いて自動化して巻き回す方法としては、代表的な巻き回し方式として、軸巻き方式（シャフト巻き方式、間隙巻き取り方式とも称される）や、接触巻き方式（タッチ巻き方式とも称される）が知られている（たとえば、特開平１１－１３９２４９号公報（特許文献１）、特開平６－１１６８３９号公報（特許文献２）、特開平６－１２３０４２号公報（特許文献３）等参照）。 On the other hand, as a method of automatically winding a strip using a machine, as a typical winding method, a shaft winding method (also called a shaft winding method or a gap winding method), a contact winding method ( (Also referred to as touch winding method) is known (for example, Japanese Patent Application Laid-Open No. 11-139249 (Patent Document 1), Japanese Patent Application Laid-Open No. 6-116839 (Patent Document 2), Japanese Patent Application Laid-Open No. 6-123042 ( See Patent Document 3)).

　上述したように、柔軟な帯状物を手作業で巻き回すこととした場合には、当然のことながら生産効率の点で劣るといった問題や、巻き回し作業の再現性を担保することが困難であるため、巻回後において巻回体の外形寸法に大きなばらつきが生じてしまうといった問題が生じてしまう。特に、上述したインクジェット塗布装置に使用されるクリーニング部材としての巻回体は、基本的には再利用が困難な消耗品であり、基板の大型化等に伴って相当量の巻回体を供給することが要求される現状においては、生産効率の向上の観点から巻回体の生産の機械化（自動化）が不可避な状況にある。 As described above, when a flexible belt is manually wound, it is naturally difficult to ensure the problem of inferior production efficiency and reproducibility of the winding work. For this reason, after winding, the problem that a big dispersion | variation will arise in the external dimension of a wound body will arise. In particular, the wound body as a cleaning member used in the above-described ink jet coating apparatus is basically a consumable that is difficult to reuse, and a considerable amount of the wound body is supplied as the substrate becomes larger. In the current situation where it is required to perform, mechanization (automation) of production of a wound body is inevitable from the viewpoint of improving production efficiency.
　しかしながら、上述した既知の軸巻き方式や接触巻き方式は、いずれも比較的強い張力をもって帯状物をきつく巻き回すことが前提とされた巻き回し方式であるため、これら巻き回し方式をそのまま伸縮性または／および吸液性に富んだ柔軟な帯状物の巻き回し方式として採用した場合には、巻回後において十分な弾性が発揮されないといった不具合や十分な吸液性が得られないといった不具合が生じてしまうことになる。 However, the known shaft winding method and contact winding method described above are winding methods based on the premise that the belt-like material is tightly wound with a relatively strong tension. / And when it is adopted as a winding method for a flexible belt-like material rich in liquid absorbency, there is a problem that sufficient elasticity is not exhibited after winding or a problem that sufficient liquid absorbency cannot be obtained. It will end up.
　そこで、本発明は、上述した問題点に鑑みてなされたものであり、柔軟な帯状物を実質的に張力がかからない状態で巻き回すことが可能な新規な巻回体の製造方法および製造装置を提供することを目的とする。 Accordingly, the present invention has been made in view of the above-described problems, and a novel wound body manufacturing method and manufacturing apparatus capable of winding a flexible belt-like object in a state where substantially no tension is applied.

A pair of drive rollers 30, 31 as a body, a drive unit (not shown) for rotationally driving the drive rollers 30, 31, a guide roller 20 as a guide member, an assist roller 32 as a biasing member, and a winding A winding body support portion for supporting the winding body 40 is mainly provided. The wound body support portion includes a pair of drive rollers 30 and 31 disposed below the wound body 40 and a pair of guide members 34 disposed along both ends in the width direction of the wound body 40. Composed.
　原反支承部は、マザーロール１０の芯材１１を支承することでマザーロール１０を回転可能に支持するものであり、実質的にマザーロール１０に回転抵抗が生じない状態（すなわち回転抵抗が小さく無視できる状態）で当該マザーロール１０を支承するものである。 The original fabric support portion supports the mother roll 10 by supporting the core material 11 of the mother roll 10 so that the mother roll 10 is substantially free from rotational resistance (that is, the rotational resistance is small). The mother roll 10 is supported in a negligible state.
　一対の駆動ローラ３０，３１は、図中に示す隙間Ｂをもって離間配置されるように略水平方向に並んで配置されており、モータ等の駆動部によって図中矢印Ａ方向に沿って同一方向に同一回転速度で回転駆動される。 The pair of drive rollers 30 and 31 are arranged in a substantially horizontal direction so as to be spaced apart with a gap B shown in the figure, and are driven in the same direction along the arrow A direction in the figure by a drive unit such as a motor. It is rotationally driven at the same rotational speed.
　ガイドローラ２０は、幅方向の両端にガイド板２１が立設されてなるローラからなり、当該ガイド板２１に帯状物４２の幅方向の両端が接触することで帯状物４２の位置決めを行なうものである。なお、ガイドローラ２０は、帯状物４２の移動に伴って従動回転するように構成されていることが好ましいが、その表面を滑らかに構成することで接触抵抗を十分に低減できる場合等には、案内部材として、ガイドローラ２０に代えて回転不能なシャフト状の部材等を利用することもできる。 The guide roller 20 is a roller in which guide plates 21 are erected at both ends in the width direction, and positions the strip 42 by contacting both ends of the strip 42 in the width direction with the guide plate 21. is there. In addition, it is preferable that the guide roller 20 is configured to be driven and rotated along with the movement of the belt-like object 42, but when the contact resistance can be sufficiently reduced by configuring the surface smoothly, As the guide member, a non-rotatable shaft-like member or the like can be used instead of the guide roller 20.
　アシストローラ３２は、支持軸３３によって回転可能に支持されており、一対の駆動ローラ３０，３１のうちの一方の駆動ローラ３０に対して付勢された状態で設置されている。アシストローラ３２は、駆動ローラ３０の表面上を搬送される帯状物４２を駆動ローラ３０との間で挟持するためのものである。なお、アシストローラ３２は、帯状物４２の移動に伴って従動回転するように構成されていることが好ましいが、その表面を滑らかに構成することで接触抵抗を十分に低減できる場合等には、付勢部材として、アシストローラ３２に代えて回転不能なプレート状の部材やブロック状の部材等を利用することもできる。 The assist roller 32 is rotatably supported by a support shaft 33 and is installed in a state of being biased with respect to one of the pair of drive rollers 30 and 31. The assist roller 32 is for sandwiching the belt-like object 42 conveyed on the surface of the drive roller 30 with the drive roller 30. The assist roller 32 is preferably configured to rotate following the movement of the belt-like object 42, but when the contact resistance can be sufficiently reduced by configuring the surface smoothly, As the urging member, a plate-like member or a block-like member that cannot rotate can be used instead of the assist roller 32.
　巻回体支承部は、巻回体４０を支承することで巻回体４０を回転可能に支持するものであり、実質的に巻回体４０に回転抵抗が生じない状態（すなわち回転抵抗が小さく無視できる状態）で当該巻回体４０を支承するものである。上述したように、巻回体支承部は、巻回体４０の下方に配置された一対の駆動ローラ３０，３１と、巻回体４０の幅方向の両端に沿って配置された一対のガイド部材３４とによって構成され、このうちのガイド部材３４は、巻回体４０の幅方向の両端が接触することで巻回体４０の位置決めを行なうものである。 The wound body support portion supports the wound body 40 so as to be rotatable by supporting the wound body 40, and a state in which no rotational resistance is generated in the wound body 40 (that is, the rotational resistance is small). The wound body 40 is supported in a negligible state. As described above, the wound body support portion includes the pair of driving rollers 30 and 31 disposed below the wound body 40 and the pair of guide members disposed along both ends in the width direction of the wound body 40. 34 of these, the guide member 34 of these positions the winding body 40 by the both ends of the width direction of the winding body 40 contacting.
　本実施の形態における巻回体の製造方法は、上述した巻回体の製造装置１Ａを利用することで実現できるものであり、図３に示すように、マザーロール１０を原反支承部にセットし、マザーロール１０から引き出された帯状物４２を図示する如くの経路に沿って這い回し、一対の駆動ローラ３０，３１を回転駆動することで巻回体４０の製造が行なわれるものである。 The method for manufacturing a wound body in the present embodiment can be realized by using the above-described wound body manufacturing apparatus 1A, and as shown in FIG. 3, the mother roll 10 is set in the original fabric support portion. Then, the wound body 40 is manufactured by rolling the belt-like object 42 drawn out from the mother roll 10 along a path as shown in the drawing and rotationally driving the pair of drive rollers 30 and 31.
　具体的には、一対の駆動ローラ３０，３１を回転駆動することにより、マザーロール１０から引き出された帯状物４２は、一方の駆動ローラ３１に接触した後にガイドローラ２０へと送られ、その後他方の駆動ローラ３０に接触して当該駆動ローラ３０上を搬送され、さらにアシストローラ３２と駆動ローラ３０とによって挟持された後に一対の駆動ローラ３０，３１間の隙間Ｂ上の位置に供給され、当該位置において転動することにより巻き回されて巻回体４０となる。 Specifically, by rotating the pair of drive rollers 30 and 31, the belt-like object 42 drawn from the mother roll 10 is sent to the guide roller 20 after contacting the one drive roller 31, and then the other The driving roller 30 is contacted with the driving roller 30 and conveyed on the driving roller 30. Further, after being sandwiched between the assist roller 32 and the driving roller 30, it is supplied to a position on the gap B between the pair of driving rollers 30 and 31. The rolled body 40 is wound by rolling at the position.
　ここで、本実施の形態における巻回体の製造方法にあっては、マザーロール１０が実質的に回転抵抗が生じない状態で支承されているため、駆動ローラ３０，３１に帯状物４２が接触することで生じる摩擦力のみによって帯状物４２がマザーロール１０から駆動ローラ３０，３１に供給される。 Here, in the manufacturing method of the wound body in the present embodiment, since the mother roll 10 is supported in a state where substantially no rotational resistance is generated, the belt-like object 42 contacts the drive rollers 30 and 31. The belt-like object 42 is supplied from the mother roll 10 to the drive rollers 30 and 31 only by the frictional force generated.
　一方、駆動ローラ３０に供給された帯状物４２は、当該駆動ローラ３０と帯状物４２との間に生じる摩擦力に基づいて駆動ローラ３０の回転に追従して駆動ローラ３０の表面上において滑ることなく搬送され、これにより、搬送後の帯状物４２が、駆動ローラ３０，３１間の隙間Ｂ上の位置に随時供給される状態となる。 On the other hand, the belt-like object 42 supplied to the driving roller 30 slides on the surface of the driving roller 30 following the rotation of the driving roller 30 based on the frictional force generated between the driving roller 30 and the belt-like object 42. As a result, the belt-like object 42 after being conveyed is supplied to the position on the gap B between the drive rollers 30 and 31 as needed.
　また、本実施の形態における巻回体の製造方法にあっては、巻回体４０が実質的に回転抵抗が生じない状態で支承されているため、駆動ローラ３０，３１が回転することで生じる回転力（すなわち、随時供給される帯状物４２の送り出し力および巻回体４０が駆動ローラ３０，３１に接触することで生じる摩擦力）に基づいて上記隙間Ｂ上の位置において図中矢印Ｃ方向に転動する。 Moreover, in the manufacturing method of the wound body in this Embodiment, since the wound body 40 is supported in the state which does not produce a rotational resistance substantially, it arises because the drive rollers 30 and 31 rotate. The direction of the arrow C in the figure at the position on the gap B based on the rotational force (that is, the feed force of the belt 42 supplied as needed and the frictional force generated when the wound body 40 contacts the drive rollers 30 and 31). Roll to.
　したがって、帯状物４２は、巻回体４０の既に巻き回されている部分によって随時巻き取られることとなり、帯状物４２が連続的に巻き回されることで図４に示す状態から図５に示す状態へと巻回体４０の巻き数が増加していくことになる。 Therefore, the belt-like object 42 is wound up at any time by the already wound portion of the wound body 40, and the belt-like object 42 is continuously wound to show the state shown in FIG. The number of windings of the wound body 40 increases to the state.
　なお、実際に巻回体４０を巻き回して製造する際には、初期段階においても帯状物４２が上記隙間Ｂ上の位置において転動することとなるように、予め帯状物４２の先端を１層または２層程度巻き回しておくことが必要であり、また所定量の帯状物４２の巻き回しが完了した後には、巻回体４０を未だ巻き回されていない部分の帯状物４２から切り離し、切り離した巻回体４０を製造装置１Ａから取り出すことが必要になる。 When the wound body 40 is actually wound and manufactured, the tip of the belt-like object 42 is set in advance so that the belt-like object 42 rolls at the position on the gap B even in the initial stage. It is necessary to wind about one layer or two layers, and after the winding of the predetermined amount of the band-like object 42 is completed, the wound body 40 is separated from the band-like object 42 which has not been wound, It is necessary to take out the wound body 40 from the manufacturing apparatus 1A.
　以上において説明したように、本実施の形態における巻回体の製造方法にあっては、帯状物４２が、駆動ローラ３０，３１に接触することで生じる摩擦力のみによってマザーロール１０から送り出されて駆動ローラ３０，３１に供給されることになり、また、駆動ローラ３０，３１に供給された帯状物４２が、駆動ローラ３０，３１の回転に追従して駆動ローラ３０，３１の表面上において搬送されることになり、さらには、駆動ローラ３０の表面上において駆動ローラ３０の回転に追従して搬送されてきた帯状物４２が、駆動ローラ３０，３１が回転することで生じる回転力のみによって駆動ローラ３０，３１上において転動することで巻き回されることになる。 As described above, in the method for manufacturing a wound body in the present embodiment, the belt-like object 42 is fed from the mother roll 10 only by the frictional force generated by contacting the drive rollers 30 and 31. The belts 42 supplied to the driving rollers 30 and 31 are conveyed on the surfaces of the driving rollers 30 and 31 following the rotation of the driving rollers 30 and 31. Furthermore, the belt-like object 42 conveyed following the rotation of the drive roller 30 on the surface of the drive roller 30 is driven only by the rotational force generated by the rotation of the drive rollers 30 and 31. Winding is performed by rolling on the rollers 30 and 31.
　すなわち、本実施の形態における巻回体の製造方法にあっては、駆動ローラ３０，３１に帯状物４２が接触することで生じる摩擦力および当該駆動ローラ３０，３１が回転することで生じる回転力のみを推進力として帯状物４２の搬送および転動が可能とされている。したがって、当該巻回体の製造方法を利用することにより、帯状物４２の巻き回しの際に実質的に帯状物４２に張力がかかっていない状態が実現されることになり、帯状物４２を弛みなくかつ緩く巻き回すことが可能になる。 That is, in the method of manufacturing a wound body in the present embodiment, the frictional force generated when the belt-like object 42 contacts the driving rollers 30 and 31 and the rotational force generated when the driving rollers 30 and 31 rotate. The belt-like object 42 can be conveyed and rolled using only the driving force. Therefore, by utilizing the method for manufacturing the wound body, a state in which no tension is applied to the belt-like object 42 when the belt-like object 42 is wound is realized, and the belt-like object 42 is slackened. It is possible to wind it loosely and gently.
　そのため、上述した本実施の形態の如くの巻回体の製造方法および製造装置を採用することにより、伸縮性および吸液性に富んだ柔軟な帯状物を実質的に張力がかからない状態で巻き回すことが可能になる。したがって、従来の巻回体の製造方法および製造装置を適用したのではその実現が困難であった帯状物の有する柔軟性を保った状態での巻回体の製造が、容易に機械化（自動化）できることになり、生産効率の向上や巻回体の外形寸法のばらつきの低減等の効果を得ることが可能になる。 Therefore, by adopting the manufacturing method and the manufacturing apparatus of the wound body as in the above-described embodiment, a flexible belt-like material rich in stretchability and liquid absorption is wound in a state where no tension is applied. It becomes possible. Therefore, the manufacture of the wound body while maintaining the flexibility of the belt-like material, which has been difficult to realize by applying the conventional method and apparatus for manufacturing the wound body, is easily mechanized (automated). As a result, it is possible to obtain effects such as improvement in production efficiency and reduction in variation in the outer dimensions of the wound body.
　なお、上述した本実施の形態においては、駆動ローラ３０に供給された帯状物４２が確実に駆動ローラ３０に接触することとなるように、駆動ローラ３０にアシストローラ３２を付設した構成とした場合を例示して説明を行なったが、当該アシストローラ３２は、必ずしも設置しなければならないものではない。たとえば、駆動ローラ３０，３１の表面を粗面化したりゴム製にしたりすることとすれば、駆動ローラ３０，３１と帯状物４２との間に生じる摩擦力を増加させることができるため、このような手法により十分な摩擦力が確保できるのであれば、帯状物４２の浮き上がりが未然に防止でき、アシストローラ３２の設置が不要となる。 In the present embodiment described above, the drive roller 30 is provided with the assist roller 32 so that the belt-like object 42 supplied to the drive roller 30 is surely in contact with the drive roller 30. However, the assist roller 32 does not necessarily have to be installed. For example, if the surfaces of the drive rollers 30 and 31 are roughened or made of rubber, the frictional force generated between the drive rollers 30 and 31 and the belt-like object 42 can be increased. If a sufficient frictional force can be ensured by such a method, the belt-like object 42 can be prevented from being lifted, and the assist roller 32 need not be installed.

　図６に示すように、本実施の形態における巻回体の製造装置１Ｂは、上述した本発明の実施の形態１における巻回体の製造装置１Ａと主として回転体の構成および巻回体支承部の構成において相違している。すなわち、本実施の形態における巻回体の製造装置１Ｂにあっては、回転体として単一の駆動ローラ３０が用いられ、巻回体支承部として、巻回体４０の下方に配置された駆動ローラ３０と、巻回体４０の幅方向の両端に沿って配置された一対のガイド部材３４と、巻回体４０の斜め下方にまで達するように傾斜して配置された一対のガイド部材３５とが用いられている。ここで、巻回体４０は、上述したガイド部材３４，３５によって四方から位置決めされてこれに接触しているため、その落下が未然に防止される。 As shown in FIG. 6, the wound body manufacturing apparatus 1 </ b> B according to the present embodiment includes the above-described wound body manufacturing apparatus 1 </ b> A according to the first embodiment of the present invention, mainly the configuration of the rotating body and the wound body support portion. The configuration is different. That is, in the wound body manufacturing apparatus 1B according to the present embodiment, a single drive roller 30 is used as the rotating body, and the drive disposed below the wound body 40 as the wound body support portion. A pair of guide members 34 disposed along both ends of the roller 30, the wound body 40 in the width direction, and a pair of guide members 35 disposed so as to be inclined obliquely below the wound body 40. Is used. Here, since the wound body 40 is positioned from four directions by the guide members 34 and 35 described above and is in contact with the guide members 34 and 35, the winding body 40 is prevented from falling.
　本実施の形態における巻回体の製造方法は、上述した本実施の形態における巻回体の製造装置１Ｂを利用することで実現できるものであり、図６に示すように、マザーロール１０を原反支承部にセットし、マザーロール１０から引き出された帯状物４２を図示する如くの経路に沿って這い回し、単一の駆動ローラ３０を回転駆動することで巻回体４０の製造が行なわれるものである。 The method for manufacturing a wound body in the present embodiment can be realized by using the wound body manufacturing apparatus 1B in the present embodiment described above. As shown in FIG. The wound body 40 is manufactured by setting the anti-bearing portion, rolling the belt-like object 42 pulled out from the mother roll 10 along a path as shown in the figure, and driving the single drive roller 30 to rotate. Is.
　具体的には、駆動ローラ３０を回転駆動することにより、マザーロール１０から引き出された帯状物４２は、従動ローラ２５を経由してガイドローラ２０へと送られ、その後駆動ローラ３０に接触して当該駆動ローラ３０上を搬送され、さらにアシストローラ３２と駆動ローラ３０とによって挟持された後に駆動ローラ３０上の位置に供給され、当該位置において転動することにより巻き回されて巻回体４０となる。 Specifically, by driving the drive roller 30 to rotate, the belt-like object 42 pulled out from the mother roll 10 is sent to the guide roller 20 via the driven roller 25, and then contacts the drive roller 30. After being conveyed on the driving roller 30 and further sandwiched between the assist roller 32 and the driving roller 30, it is supplied to a position on the driving roller 30, and rolled by rolling at the position to be wound around the wound body 40. Become.
　このように、本実施の形態における巻回体の製造方法にあっても、駆動ローラ３０に帯状物４２が接触することで生じる摩擦力および当該駆動ローラ３０が回転することで生じる回転力のみを推進力として帯状物４２の搬送および転動が可能とされている。したがって、当該巻回体の製造方法を利用することにより、帯状物４２の巻き回しの際に実質的に帯状物４２に張力がかかっていない状態が実現されることになり、帯状物４２を弛みなくかつ緩く巻き回すことが可能になる。 As described above, even in the method for manufacturing a wound body in the present embodiment, only the frictional force generated when the belt-like object 42 contacts the driving roller 30 and the rotational force generated when the driving roller 30 rotates are used. The belt-like object 42 can be conveyed and rolled as a driving force. Therefore, by utilizing the method for manufacturing the wound body, a state in which no tension is applied to the belt-like object 42 when the belt-like object 42 is wound is realized, and the belt-like object 42 is slackened. It is possible to wind it loosely and gently.

　図７に示すように、本実施の形態における巻回体の製造装置１Ｃは、上述した本発明の実施の形態２における巻回体の製造装置１Ｂと巻回体支承部の構成においてのみ相違している。すなわち、本実施の形態における巻回体の製造装置１Ｃにあっては、巻回体支承部として、巻回体４０の下方に配置された駆動ローラ３０と、巻回体４０の幅方向の両端に沿って配置された一対のガイド部材３４とが用いられており、一対のガイド部材３４には、上下方向に沿って延びるスリット３４ａが設けられている。ここで、当該スリット３４ａには、巻回体４０の巻き芯４１の端部が回転可能に挿入されており、これにより巻回体４０の落下が未然に防止されている。なお、スリット３４ａに挿入される巻き芯４１の端部は、巻き回し後において帯状物４２の幅方向の端部に沿ってこれを切断することにより除去することが可能であるため、当該端部の除去を行なうことで図１の如くの構成の巻回体４０を得ることが可能である。 As shown in FIG. 7, the wound body manufacturing apparatus 1 </ b> C in the present embodiment is different from the above-described wound body manufacturing apparatus 1 </ b> B in the second embodiment of the present invention only in the configuration of the wound body support portion. ing. That is, in the wound body manufacturing apparatus 1 </ b> C according to the present embodiment, the driving roller 30 disposed below the wound body 40 and both ends in the width direction of the wound body 40 as the wound body support portions. A pair of guide members 34 arranged along the vertical direction is used, and the pair of guide members 34 is provided with slits 34a extending in the vertical direction. Here, the end of the winding core 41 of the wound body 40 is rotatably inserted into the slit 34a, thereby preventing the wound body 40 from dropping.

　図８は、本発明の実施の形態４における巻回体の製造方法および製造装置を説明するための概念図である。次に、この図８を参照して、本発明の実施の形態４における巻回体の製造方法および製造装置について説明する。 FIG. 8 is a conceptual diagram for explaining a method of manufacturing a wound body and a manufacturing apparatus according to Embodiment 4 of the present invention. Next, with reference to this FIG. 8, the manufacturing method and manufacturing apparatus of the wound body in Embodiment 4 of this invention are demonstrated.
　図８に示すように、本実施の形態における巻回体の製造装置１Ｄは、上述した本発明の実施の形態１における巻回体の製造装置１Ａと主として回転体の構成および巻回体支承部の構成において相違している。すなわち、本実施の形態における巻回体の製造装置１Ｄにあっては、回転体として一対の駆動ローラ３０，３１に架け渡されたベルト３６が用いられ、巻回体支承部として、巻回体４０の下方に配置されたベルト３６と、巻回体４０の幅方向の両端に沿って配置された一対のガイド部材３４とが用いられており、一対のガイド部材３４には、上下方向に沿って延びるスリット３４ａが設けられている。なお、スリット３４ａが設けられたガイド部材３４については、上述した本発明の実施の形態３におけるそれと同様のものである。 As shown in FIG. 8, the wound body manufacturing apparatus 1D according to the present embodiment includes the above-described wound body manufacturing apparatus 1A according to the first embodiment of the present invention, mainly the configuration of the rotating body and the wound body support portion. The configuration is different. That is, in the wound body manufacturing apparatus 1D according to the present embodiment, the belt 36 spanned between the pair of drive rollers 30 and 31 is used as the rotating body, and the wound body is used as the wound body support portion. A belt 36 disposed below 40 and a pair of guide members 34 disposed along both ends in the width direction of the wound body 40 are used, and the pair of guide members 34 extend in the vertical direction. A slit 34a is provided. The guide member 34 provided with the slit 34a is the same as that in the third embodiment of the present invention described above.
　本実施の形態における巻回体の製造方法は、上述した本実施の形態における巻回体の製造装置１Ｄを利用することで実現できるものであり、図８に示すように、マザーロール１０を原反支承部にセットし、マザーロール１０から引き出された帯状物４２を図示する如くの経路に沿って這い回し、ベルト３６を回転駆動することで巻回体４０の製造が行なわれるものである。 The method for manufacturing a wound body in the present embodiment can be realized by using the wound body manufacturing apparatus 1D in the present embodiment described above, and as shown in FIG. The wound body 40 is manufactured by turning the belt 36 along the path as shown in the drawing and rotating the belt 36 while being set on the anti-bearing portion and drawn out from the mother roll 10.
　具体的には、駆動ローラ３０，３１を介してベルト３６を回転駆動することにより、マザーロール１０から引き出された帯状物４２は、ベルト３６に一旦接触した後にガイドローラ２０へと送られ、その後再びベルト３６に接触して当該ベルト３６上を搬送され、さらにアシストローラ３２とベルト３６とによって挟持された後にベルト３６上の所定の位置にまで搬送され、当該所定の位置において転動することにより巻き回されて巻回体４０となる。 Specifically, by rotating the belt 36 via the drive rollers 30 and 31, the belt-like object 42 pulled out from the mother roll 10 is once brought into contact with the belt 36 and then sent to the guide roller 20, and thereafter By contacting the belt 36 again and being conveyed on the belt 36, and further being sandwiched between the assist roller 32 and the belt 36, conveyed to a predetermined position on the belt 36, and rolling at the predetermined position. The wound body 40 is wound.
　このように、本実施の形態における巻回体の製造方法にあっても、ベルト３６に帯状物４２が接触することで生じる摩擦力および当該ベルト３６が回転することで生じる回転力のみを推進力として帯状物４２の搬送および転動が可能とされている。したがって、当該巻回体の製造方法を利用することにより、帯状物４２の巻き回しの際に実質的に帯状物４２に張力がかかっていない状態が実現されることになり、帯状物４２を弛みなくかつ緩く巻き回すことが可能になる。 As described above, even in the method for manufacturing a wound body in the present embodiment, only the frictional force generated by the belt 42 coming into contact with the belt 36 and the rotational force generated by the rotation of the belt 36 are propulsive force. The belt-like object 42 can be conveyed and rolled. Therefore, by utilizing the method for manufacturing the wound body, a state in which no tension is applied to the belt-like object 42 when the belt-like object 42 is wound is realized, and the belt-like object 42 is slackened. It is possible to wind it loosely and gently.
　そのため、本実施の形態の如くの巻回体の製造方法および製造装置を採用した場合にも、上述した本発明の実施の形態１において説明した効果と同様の効果を得ることができる。 Therefore, even when the winding body manufacturing method and manufacturing apparatus as in the present embodiment are employed, the same effects as those described in the first embodiment of the present invention described above can be obtained.
