Description

本発明はウエブの巻取り方法、特に紙管等の巻芯を有しないコアレスウエブロールを得る巻取り方法に関し、就中、スリッタを用いて広巾ウエブを複数の狭巾ウエブに分割するとき、両端部でスリットされ切り取られた、通常、耳と称するリボン状のウエブを巻取り再生するのに好適な巻芯のないウエブロールを得る巻取り方法に関する。   The present invention relates to a web winding method, and more particularly to a winding method for obtaining a coreless web roll having no core such as a paper tube. In particular, when a wide web is divided into a plurality of narrow webs using a slitter, both ends are provided. The present invention relates to a winding method for obtaining a web roll without a core suitable for winding and reproducing a ribbon-shaped web, usually called an ear, which is slit and cut at a portion.

広巾のウエブをスリット刃によって所要幅の複数の狭巾ウエブに分割切断するウエブの巻取りにおいて、スリット刃で複数の狭巾ウエブに切断するとき、広巾ウエブの両端に細巾リボン状の耳屑（以後単に耳と称する）が生じ、これが中間部の狭巾ウエブ製品とは別に耳巻取装置で巻き取られてその後、再活用のため再生処理に付されている。   When winding a wide web into a plurality of narrow webs with a slit blade and cutting into multiple narrow webs with a slit blade, when cutting into multiple narrow webs with a slit blade, a narrow ribbon-shaped ear dust is attached to both ends of the wide web. (Hereinafter simply referred to as an ear), which is wound up by an ear winder separately from the intermediate narrow web product, and then subjected to a recycling process for reuse.

しかし、この耳巻取装置で巻き取られた耳巻ロールを再生処理する場合、紙管などの巻芯を用いて巻いたものは巻芯と分離するため巻戻さなければならないが、耳巻取装置をコアレスにすると耳巻ロールに巻芯がないため巻き戻す必要がないので、近時、コアレス耳巻取装置による巻取りが考究され、本出願人においてもコアレスに巻取る方法を先に提案した。（例えば特許文献１参照）
このコアレス巻取り方法はシャフトの外周部を円周方向に複数分割した拡縮可能なバーで形成した巻芯シャフトの外周に着脱容易な簡易巻芯を装着し、拡大状態で固定して、該簡易巻芯外周にウエブ（耳）を巻き付け、巻き取った後、巻芯シャフトの外径を縮小して簡易巻芯に巻き取ったウエブロール（耳巻ロール）より簡易巻芯を抜き取り、ウエブロール（耳巻ロール）のみとするかせ巻き方式の方法である。
特開２０００−１８５８５３号公報 However, when the ear winding roll wound by this ear winding device is recycled, the roll wound using a core such as a paper tube must be unwound to separate from the core. When the device is made coreless, there is no need to rewind the ear roll because there is no core, so winding with a coreless ear take-up device has recently been considered, and the present applicant has also proposed a method of winding corelessly. did. (For example, see Patent Document 1)
In this coreless winding method, a simple winding core is attached to the outer periphery of a core shaft formed of an expandable / contractible bar in which the outer peripheral portion of the shaft is divided into a plurality of parts in the circumferential direction, and fixed in an expanded state, and the simplified After winding the web (ear) around the outer periphery of the core and winding it, the outer diameter of the core shaft is reduced and the simple core is removed from the web roll (ear roll) wound on the simple core. It is a skein-winding method that uses only a pinnacle roll.
JP 2000-185853 A

しかしながら、上記提案に係る巻取りはウエブの材質にもよるが、耳巻ロール内部の巻芯にかかる締付圧は非常に強力で、しかも巻取張力や巻取長さに比例して強くなるため、強度上の制限があり、あまり長く、大きく巻くことができず、実用上の問題を有していた。   However, although the winding according to the above proposal depends on the material of the web, the tightening pressure applied to the winding core inside the ear winding roll is very strong and increases in proportion to the winding tension and winding length. For this reason, there is a limitation in strength, and it is too long and cannot be rolled up greatly, which has a practical problem.

本発明は上述の如き実状に対処し、特に巻芯に係る締付圧の緩和をはかるべく拡縮コア（巻芯シャフト）の拡大状態を固定することなしにエアシリンダ等で拡がる構造にすることにより、耳を巻取るに従って上昇する締付圧がエアシリンダ等による拡縮コアを拡大させる力を上回ったとき、コアを収縮させてコアにかかる力を緩和させ、耳を大きく巻くことを可能ならしめることを目的とするものである。   The present invention addresses the actual situation as described above, and in particular, by adopting a structure that expands with an air cylinder or the like without fixing the expansion state of the expansion / contraction core (core shaft) in order to relieve the tightening pressure on the core. When the tightening pressure that rises as the ear is rolled up exceeds the force that expands the expansion / contraction core by the air cylinder, etc., the core is contracted to relieve the force applied to the core and make it possible to wind the ear large It is intended.

即ち、上記目的に適合する本発明巻取り方法は、所要の間隔を存して配設され左右の可動フレームに夫々、内方に突出させて、外周部を円周方向に複数に分割しリンクを介して拡縮可能なコアを左右２分し、互いに対向させて、回転可能に軸着すると共に、左右の可動フレーム間にエアシリンダ等よりなる伸縮機構を介装してなる巻取装置を用い、伸縮機構の作動により２分された左右の拡縮部を互いに突き当てることによりリンクを起立させ、コアを拡大させて巻取りを行い、巻取りの進行に伴って巻ロールの締付圧が上昇し、該締付圧が前記リンクによるコア拡大力を上回るに伴ってリンクを倒伏させコアを収縮させることにより前記締付圧を減少させると共に、巻取り終了後、伸縮機構の作動により突き当たっている互いのコアを分離し、後退させてウエブが巻かれた巻ロールをコアより外すことを特徴とする。なお、拡縮コアが許容を超えて収縮するとセンサーが検知するようにしておくことが好ましい。また、拡縮コアとして２分された各コア外周が先端側より基端側に向かって５〜１５°の上向きテーパを有していることが巻ロール取り出し上、好適である。   In other words, the winding method of the present invention suitable for the above-mentioned object is provided with a predetermined interval and protrudes inward to the left and right movable frames, respectively, and the outer peripheral portion is divided into a plurality of links in the circumferential direction. Using a winding device that divides a core that can be expanded and contracted via left and right, is opposed to each other, and is rotatably attached to a shaft, and an expansion and contraction mechanism such as an air cylinder is interposed between left and right movable frames. The link is erected by abutting the left and right expansion / contraction parts divided into two by the operation of the expansion / contraction mechanism, the core is expanded and winding is performed, and the winding roll tightening pressure increases as the winding progresses Then, as the tightening pressure exceeds the core expansion force by the link, the link is laid down and the core is contracted to reduce the tightening pressure. Separate cores from each other Characterized by removing the retracted so wound roll web is wound from the core. In addition, it is preferable that the sensor detects when the expansion / contraction core contracts beyond tolerance. Moreover, it is suitable for taking out the winding roll that each core outer periphery divided into two as the expansion / contraction core has an upward taper of 5 to 15 ° from the distal end side toward the proximal end side.

本発明は以上のようにリンクにより拡縮可能なコアを左右に分け、エアシリンダ等により作動させて突き当てることによりリンクを起立させてコアを拡大し、この拡大状態をエアシリンダ等によって維持すると共に巻取りによる巻ロールの締付圧によって該締付圧がコア拡大力を上回るに伴いリンクが倒伏しコアが収縮され、コアが収縮するとコア付近のウエブの張力が低下もしくは座屈し、締付圧が低下減少し、さらに巻き進むと同様の状態が繰り返されるが、ある程度コアが収縮すると、コア付近の巻ロールの剛性が高まって、あるいはコアまで締付圧が伝わらない程、巻き太ってコアが収縮しなくなると巻取りを終わり、伸縮機構を作動して突き当たっているコアを分離し、後退させるので従来のように拡縮コアの拡大状態を機械的に固定するのと異なり、エアシリンダ等による拡がりと共にリンクにより締付圧を緩和させることができ、コアの拡縮が円滑になり、紙管等を用いることなくウエブや耳だけの巻取りを容易にし、その取り出しを簡易化することができる。なお、２分された各コア外周が先端側より基端側に上向き傾斜を有するときはより取り出しが容易である
また、上述の如く、ある程度コアが収縮するとコア付近の巻ロールなどの剛性が高まり、コアまで締付圧が伝わらない程、巻き太るので結果としてウエブや耳を大きく巻くことができる効果がある。 In the present invention, as described above, the core that can be expanded and contracted by the link is divided into left and right, and the core is expanded by operating the abutment with an air cylinder or the like to raise the link, and this expanded state is maintained by the air cylinder or the like. As the tightening pressure exceeds the core expansion force due to the winding pressure of the winding roll, the link collapses and the core contracts, and when the core contracts, the tension of the web near the core decreases or buckles. If the core is contracted to some extent, the stiffness of the winding roll near the core increases or the tightening pressure is not transmitted to the core so that the core becomes thicker. When it no longer shrinks, the winding is finished and the striking core is separated and moved backward by operating the expansion / contraction mechanism, so the expansion state of the expansion / contraction core is mechanically changed as before. Unlike setting, the tightening pressure can be relaxed by the link along with the expansion by the air cylinder, etc., the core can be expanded and contracted smoothly, and it is easy to wind only the web and ears without using a paper tube, The extraction can be simplified. In addition, it is easier to take out when the outer circumference of each divided core has an upward slope from the distal end side to the proximal end side. As described above, when the core contracts to some extent, the rigidity of the winding roll near the core increases. Since the winding pressure is so thick that the tightening pressure is not transmitted to the core, there is an effect that the web and the ear can be wound large.

以下、更に添付図面を参照し、本発明の具体的態様について説明する。図１〜２は本発明方法を実施する巻取装置の1例で、図において１はレール２に沿って移動可能な可動フレームであり、適宜、所要の間隔を存して左右に対向して配設されており、両可動フレーム間にはエアシリンダからなる伸縮機構３が亘設されていて、その伸縮作動により両フレーム間の間隔を巻取り時には狭く（図１）、また、取出し時には広く（図２）広狭可能に保持し得るようになっている。   Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. 1 and 2 show an example of a winding device for carrying out the method of the present invention. In the figure, reference numeral 1 denotes a movable frame that can move along a rail 2 and is opposed to the right and left with a necessary interval. An expansion / contraction mechanism 3 comprising an air cylinder is provided between the movable frames, and the expansion / contraction operation narrows the space between the two frames during winding (FIG. 1) and widens during extraction. (FIG. 2) It can hold | maintain so that it can be narrowed.

これら両可動フレーム１には夫々、 ベアリング１０で回動可能に支承された巻取軸１１が左右対向して巻取枠９を通し内方に突設されており、夫々の先端部外周にコイルバネ８を介して巻取ドラム（以後、コアと称する）５が装着されている。そして一方の巻取軸、図では左方の巻取軸のみがモータ４に連動された伝動プーリ１２を介し回転駆動が付与されている。   Each of these movable frames 1 is provided with a winding shaft 11 rotatably supported by a bearing 10 so as to be opposed to the left and right and projecting inward through the winding frame 9. A winding drum (hereinafter referred to as a core) 5 is mounted via 8. Only one winding shaft, in the drawing, the left winding shaft is rotationally driven through a transmission pulley 12 linked to the motor 4.

巻取ドラム５（コア）は外周部を複数に分割されたバー６がリンク機構の如き拡縮機構７を有してリンクの起立によりコア径を拡大し（第１図（ロ）参照）、リンク機構の倒伏によりコア径が縮小（第２図（ロ）参照）して拡縮可能なる如く形成されていると共に、通常のコアが巻き幅の長さであるのに対し、図示の如く巻き幅を２分した長さとなっていて、２分された長さで左右夫々の巻取軸１１外周に巻取枠９に対しコイルバネ８を介して装着されている。そして、左右の可動フレーム１が移動し、夫々のフレームの巻取軸１１に装着された拡縮コア５は、これを突き当てると夫々のコア５のリンク７が起立してコア径を拡大し、巻取りを可能とすると共に、巻取りに従って締付圧が上昇し、この締付圧がエアシリンダ及びリンク機構による拡大力を上回るとリンクは次第に倒伏し、コア径を収縮させると共に、コアが収縮するとコア付近の張力が低下もしくは座屈し、締付圧が減少し、さらに巻くと同様な状態が繰り返されてある程度までコアが収縮し、コアに大きな力が働かなくなると、コア外周に巻かれた巻きロールＲの抜き取りを容易にし、巻取り終了と共に更にエアシリンダ等の伸縮機構３の作動により可動フレーム１を後退させると、コア５は左右に分離され両者の間で巻き取った巻きロールＲがコア５より外れ易くなる。   The winding drum 5 (core) has a bar 6 having an outer peripheral portion divided into a plurality of expansion / contraction mechanisms 7 such as a link mechanism, and the core diameter is expanded by raising the link (see FIG. 1 (b)). The core diameter is reduced (see Fig. 2 (b)) and can be enlarged and reduced by the mechanism collapse, and the normal core has a winding width, whereas the winding width is reduced as shown in the figure. The length is divided into two, and the two divided lengths are attached to the outer periphery of the right and left winding shafts 11 with respect to the winding frame 9 via coil springs 8. Then, the right and left movable frames 1 move, and when the expansion / contraction cores 5 mounted on the winding shafts 11 of the respective frames come into contact with each other, the links 7 of the respective cores 5 stand up to increase the core diameter, In addition to enabling winding, the tightening pressure increases according to winding, and when this tightening pressure exceeds the expansion force of the air cylinder and the link mechanism, the link gradually collapses, causing the core diameter to contract and the core to contract. Then, the tension near the core decreased or buckled, the tightening pressure decreased, and the core was contracted to a certain extent by repeating the same state when wound further, and when a large force did not work on the core, it was wound around the core When the winding roll R is easily pulled out, and the movable frame 1 is further retracted by the operation of the expansion / contraction mechanism 3 such as an air cylinder at the end of winding, the core 5 is separated into left and right and the winding wound between the two. Roll R is easily disengaged from the core 5.

なお、図１，２においては伸縮機構としてエアシリンダ３が図示されているが、エアシリンダに限らず、例えば図３に示すようにネジ機構１３を配してモータ１４による正逆回動によっても可能であり、更にバネの如き機構を介設しても同様であり、何れも本発明の含むところである。また、コアの複数に分割されたバー６に左右夫々先端側より基端側に向かって５〜１５°広がるテーパを設け、コア外周に傾きを付与することも好適である。

次に以上のような巻取装置を用いて本発明に係る巻取りを行うには、先ず図１に示すように可動アーム開閉用エアシリンダ３を作動させて各可動アームを内方に移動させると左右のコア５の先端が突き当たりリンクの起立により既知の手段によって広巾のウエブがスリット刃によって分割切断された狭巾ウエブあるいは複数のウエブに分割切断するとき、広巾ウエブの両端縁に生じた耳ウエブを巻き取る。このとき、拡縮コア５の拡大状態は機械的に固定されることなく、リンク機構とエアシリンダあるいはバネで保持される。 1 and 2, the air cylinder 3 is shown as an expansion / contraction mechanism. However, the air cylinder 3 is not limited to the air cylinder, and for example, a screw mechanism 13 may be provided as shown in FIG. This is possible even if a mechanism such as a spring is provided, and both are included in the present invention. It is also preferable that the bar 6 divided into a plurality of cores is provided with a taper that extends 5 to 15 ° from the distal end side toward the proximal end side to impart inclination to the outer periphery of the core.

Next, in order to perform winding according to the present invention using the winding device as described above, first, the movable arm opening / closing air cylinder 3 is operated to move each movable arm inward as shown in FIG. When the wide web is divided and cut into a plurality of narrow webs or a plurality of webs that are divided and cut by a slit blade by the known means with the ends of the left and right cores 5 abutting, the ears formed at both edges of the wide web Wind up the web. At this time, the expanded state of the expansion / contraction core 5 is not fixed mechanically but is held by a link mechanism and an air cylinder or a spring.

そして、上記ウエブＷを巻き取るに従って、コアにかかる締付圧が上昇し、その締付圧がリンクとエアシリンダなど伸縮機構によるコアを拡大せさる力を上回ると、コア内のリンクが倒伏を始め、少し収縮する。コアが収縮するとコア付近の張力が低下又は座屈して、締付圧が減少し、更に巻き進むと同様の状態が繰り返され、、ある程度コアが収縮すると、コア付近の巻ロールの剛性が高まり、コアまで締付圧が伝わらない程、巻き太ってコアが収縮しなくなる。   As the web W is wound up, the tightening pressure applied to the core increases. When the tightening pressure exceeds the force that expands the core by the expansion mechanism such as the link and the air cylinder, the link in the core collapses. At first, it shrinks a little. When the core contracts, the tension near the core decreases or buckles, the tightening pressure decreases, and when the winding proceeds further, the same state is repeated.When the core contracts to some extent, the rigidity of the winding roll near the core increases, As the tightening pressure is not transmitted to the core, the core becomes thicker and the core does not shrink.

このようにしてコアが収縮し、締付圧が働かなくなるとシリンダ等の伸縮機構を作動させると図２に示すように、左右の可動フレーム間の間隔が広がり、同時に収縮したコアが巻ロールＲから抜かれ、巻ロールがコア５から外れ、紙管等のコアを有しない巻ロールが得られる。なお、コア外周が前記によるテーパを有しているときは、より巻ロールの取り出しが容易である。   When the core contracts in this way and the tightening pressure stops working, when the expansion mechanism such as a cylinder is operated, the space between the left and right movable frames is widened as shown in FIG. The winding roll is removed from the core 5, and a winding roll having no core such as a paper tube is obtained. In addition, when the core outer periphery has the taper according to the above, it is easier to take out the winding roll.

以上のようにしてコアの拡縮が円滑になり、コアレス巻ロールを容易に取り出すことができる。なお、本発明はスリッタにより分割切断された狭巾ウエブの巻取り及び分割切断時のウエブ端部の耳巻取りに使用される外、一般のウエブ巻取りに使用することも可能である。   As described above, the core can be smoothly expanded and contracted, and the coreless winding roll can be easily taken out. The present invention can be used not only for winding narrow webs cut and cut by a slitter, and for winding the web ends at the time of split cutting, but also for general web winding.
