Description

【0001】
【産業上の利用分野】
本発明は、スパンデックス等の弾性フィラメント糸の巻き取り装置に関する。さらに詳細には、狭い空間領域で、同時に紡糸された複数の弾性フィラメント糸を効率よく巻き取る装置に関する。
【0002】
【従来の技術】
同時に紡糸された複数本の弾性フィラメント糸を巻き取る際には、巻き取り装置は並列に配置される。例えば、16本のフィラメント糸を巻き取る場合、8エンド用巻き取り装置を2台並列に配列する。しかし、この方法では狭い空間で、即ち、短い紡糸筒間ピッチで、多くのフィラメント糸を巻き取ることはできない。更に、1つの紡糸筒から24本のフィラメント糸を巻き取る場合は、8エンド用巻き取り装置を3台並列配置する必要があり、16本の場合の1.5倍の空間が必要になる。32本のフィラメント糸を巻き取る場合は、8エンド用巻き取り装置を4台並列配置する必要があり、16本の場合の2倍の空間が必要にる。
【0003】
少ないスペースで多数のフィラメント糸を巻き取る巻き取り装置は、特開平6−9154号公報、特開平6−174040号公報に開示されている。これらは巻き取りボビンの自動切り替えのスペースに関するものおよび巻き取りロールの駆動に関するものであり、フィラメント糸を垂直方向に巻き取る方法が開示されている。この装置は、フィラメント糸の本数に応じて巻き取り装置を並列に配列する必要があり、紡糸筒間の距離は巻き取り装置の大きさが制約となるために広い空間を必要とする。
【0004】
【発明が解決しようとする課題】
多数本のフィラメント糸を巻き取る場合、従来の垂直真下に巻き取る方法では、ボビンを水平方向に配列する必要がある。また、自動切り替えのボビンのターレットのための空間が必要なことから、巻き取り装置の機幅を大幅に縮小することは困難である。従って、ボビンを水平方向に配列した巻き取り装置ではどうしても幅が広くなり、紡糸筒間の距離を広くとる必要がある、という問題点があった。
【0005】
本発明の目的は、従来同様の巻き姿、解舒性等が各エンドの巻き糸で均一な特性を示す巻き玉を得ることができ、小さいスペースで多数のフィラメント糸を巻き取ることができる、空間生産性に優れた弾性フィラメント糸の糸巻き取り装置を提供することにある。
【0006】
【課題を解決するための手段】
本発明者らは、巻き取りボビンを縦方向に複数段配列し、従来の垂直真下への巻き取りを水平方向とのなす角度を0゜以上、45゜以下の範囲に糸を走行させることにより、従来同様の巻姿、巻き玉からの糸の解舒性を有し、小さい空間で多数の弾性フィラメント糸を巻き取ることができることを見い出し本発明に到達した。
【0007】
即ち、本発明は、紡糸された複数本の弾性フィラメント糸を巻き取る装置であり、フィラメント糸の集束装置、オイリング装置、及び各フィラメント糸に対応した糸道変更ロール、綾振り装置、フリクションロール及び巻き取りボビンを有し、巻き取りボビンは間隔をおいて垂直方向に配列され、糸道変更ロールは各巻き取りボビンに対応して、フィラメント糸を水平方向に対し0゜以上、45゜以下の方向に偏向させて巻き取りボビンに供給するように配置され、フリクションロールは巻き取りボビンに接することができると共に、圧力調節器により糸道変更ロールから出た直後のフィラメント糸の進行方向と同一方向に巻き取りボビンを加圧可能とした弾性フィラメント糸巻き取り装置である。
【0008】
フリクションロールの接圧が糸道変更ロールから出た直後の糸の進行方向と同一方向でない場合には、ボビン上の巻き径が大きくなるにつれて、糸道変更ロールから巻き玉までの糸道が変化する。そのため、巻き玉の綾形状を一定にするには綾振り装置も糸道の変化に追従して動かす必要があり複雑な装置となる。従って、フリクションロールは糸道変更ロールから出た直後の糸の進行方向と平行に接圧させる必要がある。
【0009】
糸道変更ロールから出た直後の糸の進行方向は、水平に対し0゜以上、45゜以下の角度の範囲内で定められるが、0゜、即ち、水平方向に近づく程糸道変更ロールの高さが低くでき好ましい。45゜を越えると糸道変更ロールが高い位置となり糸付けの作業が困難となる。従って、糸道変更ロールから出た直後の糸の進行方向は、水平に対し0゜以上、45゜以下の角度範囲が必要である。糸付けの作業性から、好ましくは0〜20゜、更に好ましくは0〜10゜である。
【0010】
巻き取り装置の機幅を小さくするため、糸道変更ロールから綾振り装置までの距離を小さくする必要があるが、糸道変更ロールから綾振りの中心位置への糸道とボビンの中央の位置と綾振りの中心位置とを結ぶ線とのなす角度が、平面図上で好ましくは5゜以内、より好ましくは2゜以内となるように集束装置から糸道変更ロールまでの間の糸道を規制することが好ましい。そのためには、集束装置のピッチをボビンのピッチと合わせるか、糸道変更ロール以前の糸道にガイドを設ける。この角度が5゜を越えると綾振りガイドへの糸の進入角度が各エンドで異なるため、巻き取られたボビンからの糸の解舒張力のばらつきが大きくなりやすい。
【0011】
本発明の巻き取り装置には、巻き上がった巻き玉上の糸の伸張率を大きくすることなく安定に巻き取るため、綾振り装置の後で巻き取り速度に対し好ましくは1.05倍以上、より好ましくは1.2倍以上の速度でオーバーフィードする駆動ロールを設置することができる。
オーバーフィードロールを設置することにより、糸道変更ロール、ゴデットロールに糸が巻き付くことなく低張力で巻き取ることができ、より残留収縮率の小さい巻き玉の糸を得ることができる。更に、巻き玉上の糸の収縮力に抗すためボビンの肉厚を厚くするなどの、ボビンの強度アップが不要となる。
【0012】
本発明の巻き取り装置にオーバーフィードロールを設置する場合、オーバーフィードロールの後に糸がリラックスする空間を設け、その間の糸長、即ちオーバーフィードロールと巻き玉との接線の長さが一定となるようなロール配置をとることが好ましい。この接線長を一定にすることにより、巻き玉の巻き姿がより良好なものとなる。
【0013】
本発明を図面に基づいて説明する。図1は、本発明の弾性フィラメント糸の糸巻き取り装置の例を示す図である。紡糸筒から出たフィラメント糸1は集束装置2で集合され、第1ゴデットロール3にて引き取られた後に、第2ゴデットロール4、オイリングロール5を経て各糸道変更ロール6にて縦方向に配列した巻き取り装置に巻き取られる。この際、糸道変更ロール6から巻き玉までの糸の走行方向は、水平から0゜〜45゜である。糸道変更ロール6と綾振り装置7との距離を短くしたことによる綾振り装置7への糸の進入角度のエンド間ばらつきをなくすために、集束装置2で規制するフィラメント糸のピッチと巻き取りボビン8のピッチとを合わせることで、糸道変更ロール6から綾振りの中心への糸道とボビン中央の位置と綾振りの中心位置とのなす角は平面図上で0゜〜5゜好ましくは2゜以下とする。図1では、集束装置2で糸道を規制しているが、糸道変更ロール6以前の段階で、ガイド等により糸道を規制してもよい。
【0014】
低張力で安定にボビンに巻き取るために、トラバース装置7の後に巻き取り速度、即ちフリクションロール9の周速に対して1.05倍、好ましくは1.2倍以上の速度でオーバーフィードする駆動ロール10を設置し、その後、図2に示す空間L、即ち、オーバーフィード駆動ロールと巻き玉の接線長の空間を経てボビン8に巻き取られる。巻き玉は、フリクションロール9により一定速度で回転し、糸の進入方向、即ち、糸道変更ロール6とオーバーフィードロール10の接線方向にフリクションロール9にてボビン8に接圧装置(図示していない)で接圧をかけながら巻き取る。接圧は、糸道変更ロール6からでた直後の糸道と平行に加える。
【0015】
【発明の実施の形態】
以下に本発明を実施例により説明するが、本発明は実施例により何ら限定されるものではない。
【0016】
【実施例1】
ポリウレタンフィラメント糸40dを、巻き取り速度800m/分で本発明の巻き取り装置により巻き取った。巻き取り装置の機幅は1100mmで、糸道変更ロールは縦方向(鉛直方向)に3本設置し、各々の糸道変更ロールに対応して8エンド巻き取ることができる巻き取り装置を設置した。糸道変更ロール後の糸道は水平方向に走行させ、糸道変更ロールから綾振りの中心位置への糸道(空管時の走行距離は350mm)とボビンの中央と綾振りの中心位置とを結ぶ線とのなす角度が平面図上で実質的に0゜となるように収束装置のエンド間ピッチを設定した。
【0017】
巻き取り装置にはオーバーフィード駆動ロールを設けた。ロール速度は巻き取り速度の1.3倍とした。この時、オーバーフィード駆動ロールとフリクションロールの中心線は鉛直方向に配列し、3つのボビン中心線にと平行にした。更に、オーバーフィード駆動ロールとボビンとの糸の空間走行距離が巻き径に依らず一定となるように、ボビン軸の中心はフリクションロールの上面水平線上に設置した。
【0018】
この巻き取り装置で巻き上がった巻き玉は、糸の解舒張力のエンド間のばらつきが0.3gであった。オンチーズでの糸の伸張率は9%と低く、巻き姿も以下の従来法として示す比較例の場合と同等であった。
【0019】
【比較例1】
従来の巻き取り装置を用い、実施例1と同様に40dのポリウレタンフィラメント糸を800m/分の速度で巻き取った。即ち、図3に示すように8エンド用巻き取り装置3台を並列に並べ、巻き取りボビン8及び糸道変更ロール4を3本水平に配列し、集束装置2、第1ゴデットロール3、オイリングロール5を通過したフィラメント糸を、糸道変更ロール4通過後、鉛直方向に走行させながら巻き取りボビンへ巻き取った。比較例で得た巻き玉は、糸の解舒張力のエンド間ばらつきが0.3gであり、巻き姿も良好であった。しかし、巻き取り装置の幅は1600mmであり、実施例1の約1.5倍であった。オンチーズでの糸の伸張率は15%と高かった。
【0020】
【発明の効果】
本発明の巻き取り装置によれば、紡糸された複数本の弾性フィラメント糸を狭い空間、即ち、短い紡筒間ピッチで、良好な巻き姿で、エンド間で糸の解舒張力のばらつきが小さく、オンチーズ上での糸の伸張率が小さい状態で巻き取ることができる。

[Industrial application fields]
The present invention relates to a winding device for elastic filament yarn such as spandex. More specifically, the present invention relates to an apparatus for efficiently winding a plurality of elastic filament yarns spun simultaneously in a narrow space region.
[0002]
[Prior art]
When winding a plurality of elastic filament yarns spun simultaneously, the winding device is arranged in parallel. For example, when winding 16 filament yarns, two 8-end winding devices are arranged in parallel. However, in this method, many filament yarns cannot be wound in a narrow space, that is, with a short pitch between the spinning cylinders. Furthermore, when 24 filament yarns are wound from one spinning cylinder, it is necessary to arrange three 8-end winding devices in parallel, and 1.5 times as much space as in the case of 16 windings is required. When winding 32 filament yarns, it is necessary to arrange four 8-end winding devices in parallel, which requires twice as much space as in the case of 16.
[0003]
A winding device for winding a large number of filament yarns in a small space is disclosed in JP-A-6-9154 and JP-A-6-174040. These relate to the space for automatic switching of the winding bobbin and the driving of the winding roll, and a method for winding the filament yarn in the vertical direction is disclosed. In this apparatus, it is necessary to arrange winding devices in parallel according to the number of filament yarns, and the distance between the spinning cylinders requires a large space because the size of the winding device is limited.
[0004]
[Problems to be solved by the invention]
When winding a large number of filament yarns, it is necessary to arrange the bobbins in the horizontal direction in the conventional method of winding directly below the vertical. In addition, since a space is required for the turret of the automatic switching bobbin, it is difficult to greatly reduce the machine width of the winding device. Therefore, the winding device in which the bobbins are arranged in the horizontal direction has a problem that the width is inevitably wide and it is necessary to increase the distance between the spinning cylinders.
[0005]
The purpose of the present invention is to obtain a wound ball having uniform characteristics in the winding shape of each end, unwinding properties, etc., as in the past, and to wind up a large number of filament yarns in a small space. An object of the present invention is to provide an elastic filament yarn winding device excellent in space productivity.
[0006]
[Means for Solving the Problems]
The present inventors have arranged a plurality of winding bobbins in the vertical direction, and running the yarn within an angle of 0 ° or more and 45 ° or less, where the conventional winding right below the vertical direction is made with the horizontal direction. The inventors have found that the present invention has the same winding shape and unwinding property of the yarn from the wound ball and can wind up a large number of elastic filament yarns in a small space.
[0007]
That is, the present invention is a device for winding a plurality of spun elastic filament yarns, a filament yarn converging device, an oiling device, a yarn path changing roll corresponding to each filament yarn, a traversing device, a friction roll, The take-up bobbins are arranged in the vertical direction at intervals, and the yarn path changing rolls correspond to each take-up bobbin so that the filament yarn is 0 ° or more and 45 ° or less with respect to the horizontal direction. The friction roll can be in contact with the take-up bobbin while being deflected in the direction, and can be in contact with the take-up bobbin. This is an elastic filament yarn winding device in which the winding bobbin can be pressurized.
[0008]
If the contact pressure of the friction roll is not the same as the direction of travel of the yarn immediately after coming out of the yarn path changing roll, the yarn path from the yarn path changing roll to the winding ball changes as the winding diameter on the bobbin increases. To do. For this reason, in order to keep the winding shape of the winding ball constant, the traversing device also needs to be moved following the change in the yarn path, which is a complicated device. Therefore, the friction roll needs to be contacted in parallel with the yarn traveling direction immediately after coming out of the yarn path changing roll.
[0009]
The direction of travel of the yarn immediately after coming out of the yarn path changing roll is determined within an angle range of 0 ° or more and 45 ° or less with respect to horizontal. The height can be lowered, which is preferable. If it exceeds 45 °, the yarn path changing roll will be at a high position, and the threading operation will be difficult. Accordingly, the traveling direction of the yarn immediately after coming out of the yarn path changing roll needs to have an angle range of 0 ° to 45 ° with respect to the horizontal. From the viewpoint of yarn workability, the angle is preferably 0 to 20 °, more preferably 0 to 10 °.
[0010]
In order to reduce the machine width of the winding device, it is necessary to reduce the distance from the yarn path changing roll to the traverse device, but the center of the yarn path and the bobbin from the yarn path changing roll to the traverse center position. The yarn path between the focusing device and the yarn path changing roll is adjusted so that the angle formed by the line connecting the center position of the traverse and the traverse center is preferably within 5 °, more preferably within 2 ° on the plan view. It is preferable to regulate. For this purpose, the pitch of the focusing device is matched with the pitch of the bobbin or a guide is provided on the yarn path before the yarn path changing roll. When this angle exceeds 5 °, the yarn entry angle to the traverse guide differs at each end, and therefore, the variation in the unwinding tension of the yarn from the wound bobbin tends to increase.
[0011]
In the winding device of the present invention, in order to stably wind without increasing the elongation rate of the yarn on the wound ball, preferably 1.05 times or more with respect to the winding speed after the traverse device, More preferably, a drive roll that overfeeds at a speed of 1.2 times or more can be installed.
By installing the overfeed roll, the yarn can be wound with low tension without being wound around the yarn path changing roll and the godet roll, and a wound ball thread having a smaller residual shrinkage can be obtained. Further, it is not necessary to increase the strength of the bobbin such as increasing the thickness of the bobbin in order to resist the contraction force of the yarn on the wound ball.
[0012]
When the overfeed roll is installed in the winding device of the present invention, a space for relaxing the yarn is provided after the overfeed roll, and the yarn length between them, that is, the length of the tangent line between the overfeed roll and the wound ball is constant. It is preferable to take such a roll arrangement. By making this tangent length constant, the winding shape of the wound ball becomes better.
[0013]
The present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an example of a yarn winding device for an elastic filament yarn of the present invention. Filament yarns 1 coming out of the spinning cylinders are gathered by a bundling device 2, taken up by a first godet roll 3, and then arranged in a longitudinal direction by each yarn path changing roll 6 through a second godet roll 4 and an oiling roll 5. It is wound up on a winding device. At this time, the traveling direction of the yarn from the yarn path changing roll 6 to the wound ball is 0 ° to 45 ° from the horizontal. In order to eliminate the end-to-end variation of the yarn entry angle to the traverse device 7 due to the shortened distance between the yarn path changing roll 6 and the traverse device 7, the pitch and winding of the filament yarn regulated by the converging device 2 are eliminated. By matching the pitch of the bobbin 8, the angle between the yarn path from the yarn path changing roll 6 to the center of traversing, the center position of the bobbin and the center position of traversing is preferably 0 ° to 5 ° on the plan view. Is 2 ° or less. In FIG. 1, the yarn path is regulated by the converging device 2, but the yarn path may be regulated by a guide or the like before the yarn path changing roll 6.
[0014]
In order to stably wind around the bobbin with a low tension, a drive that overfeeds at a speed of 1.05 times, preferably 1.2 times or more of the winding speed after the traverse device 7, that is, the peripheral speed of the friction roll 9. After the roll 10 is installed, the roll 10 is wound around the bobbin 8 through the space L shown in FIG. 2, that is, the space of the tangent length between the overfeed drive roll and the wound ball. The wound ball is rotated at a constant speed by the friction roll 9 and is in contact with the bobbin 8 by the friction roll 9 in the yarn entry direction, that is, the tangential direction of the yarn path changing roll 6 and the overfeed roll 10 (not shown). No)) and take up while applying contact pressure. The contact pressure is applied parallel to the yarn path immediately after coming out of the yarn path changing roll 6.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
EXAMPLES The present invention will be described below with reference to examples, but the present invention is not limited to the examples.
[0016]
[Example 1]
The polyurethane filament yarn 40d was wound up by the winding device of the present invention at a winding speed of 800 m / min. The machine width of the winding device is 1100 mm, three yarn path changing rolls are installed in the vertical direction (vertical direction), and winding devices that can wind up to 8 ends corresponding to each yarn path changing roll are installed. . The yarn path after the yarn path changing roll is moved in the horizontal direction, and the yarn path from the yarn path changing roll to the traverse center position (travel distance when empty pipe is 350 mm), the center of the bobbin, and the traverse center position The end-to-end pitch of the converging device was set so that the angle formed by the line connecting the two becomes substantially 0 ° on the plan view.
[0017]
The winder was provided with an overfeed drive roll. The roll speed was 1.3 times the winding speed. At this time, the center lines of the overfeed drive roll and the friction roll were arranged in the vertical direction and parallel to the three bobbin center lines. Further, the center of the bobbin shaft was set on the upper horizontal line of the friction roll so that the space travel distance of the yarn between the overfeed drive roll and the bobbin was constant regardless of the winding diameter.
[0018]
The wound ball wound up by this winding device had a variation of 0.3 g between ends of the unwinding tension of the yarn. The on-cheese yarn elongation rate was as low as 9%, and the winding shape was equivalent to that of the comparative example shown as the conventional method below.
[0019]
[Comparative Example 1]
Using a conventional winding device, a 40d polyurethane filament yarn was wound at a speed of 800 m / min in the same manner as in Example 1. That is, as shown in FIG. 3, three 8-end winding devices are arranged in parallel, the winding bobbin 8 and the yarn path changing roll 4 are horizontally arranged, the focusing device 2, the first godet roll 3, and the oiling roll. After passing through the yarn path changing roll 4, the filament yarn that passed through 5 was wound around a winding bobbin while running in the vertical direction. The wound ball obtained in the comparative example had an end-to-end variation of the unwinding tension of the yarn of 0.3 g, and the winding shape was also good. However, the width of the winding device was 1600 mm, which was about 1.5 times that of Example 1. The on-cheese yarn elongation was as high as 15%.
[0020]
