Description

本発明は、糸を給糸ボビンから解舒してパッケージに巻き返す自動ワインダーに関するものである。   The present invention relates to an automatic winder that unwinds a yarn from a yarn supplying bobbin and rewinds it on a package.

自動ワインダーは、リング精紡機等で生産された給糸ボビンから紡績糸を解舒して、多数本の給糸ボビンから解舒された糸を糸継ぎしながらパッケージに巻き返す。パッケージの生産性は巻取り速度に大きく依存するので、高速に巻き取る自動ワインダーが要望される。しかし、高速巻取りには、給糸ボビンから糸を高速に解舒しなければならず、この高速解舒に伴って糸の解舒張力は大きく変動する。この解舒張力の変動によって、輪抜けのように糸が互いに絡み合って一気に解舒されるスラッフィングや解舒される糸の接触による毛羽立ち等が発生する。   The automatic winder unwinds the spun yarn from a yarn feeding bobbin produced by a ring spinning machine or the like, and rewinds the yarn unwound from a large number of yarn feeding bobbins while splicing the yarn. Since the productivity of the package greatly depends on the winding speed, an automatic winder that winds at high speed is desired. However, for high-speed winding, the yarn must be unwound at a high speed from the yarn feeding bobbin, and the unwinding tension of the yarn greatly varies with this high-speed unwinding. Due to the fluctuation of the unwinding tension, the yarns are entangled with each other as in the case of slipping out, and the luffing caused by the contact of the yarn being unwound or the like is generated.

このスラッフィング等を抑制するために、特許文献１や特許文献２等の解舒補助装置を備えた自動ワインダーが提案されている。この自動ワインダーによれば、給糸ボビンのバルーンや走行糸のテンションを制御することにより、スラッフィングや毛羽立ちを減少できる。しかし、特に細番手の紡績ボビンを解舒する場合には、この自動ワインダーであっても、給糸ボビンの糸量が少なくなってくると、スラッフィングによる糸切れや毛羽立ち等の発生を阻止するのに限界があった。
特許第３０３３３７０号公報 特許第２９３６９１７号公報 In order to suppress this sluffing etc., the automatic winder provided with the unwinding assistance apparatus of patent document 1, patent document 2, etc. is proposed. According to this automatic winder, sluffing and fluffing can be reduced by controlling the balloon of the yarn feeding bobbin and the tension of the running yarn. However, especially when unwinding a fine bobbin, even with this automatic winder, if the yarn amount of the yarn feeding bobbin decreases, the occurrence of yarn breakage or fluffing caused by sluffing is prevented. There was a limit.
Japanese Patent No. 3033370 Japanese Patent No. 29361717

そこで本発明が解決しようとする課題は、細番手等の様々な糸番手や糸種の給糸ボビンであっても、スラッフィングや毛羽立ち等を抑制可能な自動ワインダーを提供することにある。   Therefore, the problem to be solved by the present invention is to provide an automatic winder capable of suppressing sluffing and fluffing even with various yarn counts such as fine counts and yarn feeding bobbins of various yarn types.

本発明に係る自動ワインダーは、給糸ボビンから糸を解舒してパッケージに巻き返す自動ワインダーにおいて、給糸ボビンを軸芯を中心に糸の解舒方向に回転駆動して回転駆動して、糸を積極的に解舒するための回転駆動手段を備えている。   An automatic winder according to the present invention is an automatic winder that unwinds a yarn from a yarn supplying bobbin and winds it back to a package. The yarn winding bobbin is driven to rotate in the yarn unwinding direction around the shaft core to rotate the yarn. Rotation drive means for positively unwinding is provided.

好ましくは、パッケージに接触して回転駆動させるドラムを備えており、回転駆動手段は、給糸ボビンの回転速度をドラムの回転速度以上にする。   Preferably, a drum that rotates in contact with the package is provided, and the rotation driving means sets the rotation speed of the yarn feeding bobbin to be equal to or higher than the rotation speed of the drum.

さらに好ましくは、回転駆動手段を制御するための制御手段と、給糸ボビンの残糸量を検出するための検出手段とを備えており、制御手段は、検出手段による給糸ボビンの残糸量に伴って給糸ボビンの回転速度を変化させる。   More preferably, it comprises control means for controlling the rotation drive means and detection means for detecting the remaining yarn amount of the yarn feeding bobbin, and the control means is the remaining yarn amount of the yarn feeding bobbin by the detecting means. Accordingly, the rotational speed of the yarn feeding bobbin is changed.

本発明に係る自動ワインダーは、上記のように、給糸ボビンを軸心を中心に巻き付け方向とは逆方向に高速回転駆動する手段を備えている。この回転駆動手段により、糸が給糸ボビンから積極的に解舒されるので、高速解舒による糸のテンション変動を著しく減少させ、細番手の給糸ボビンであってもスラッフィングによる糸切れや毛羽立ち等の発生を殆どなくすことができる。   As described above, the automatic winder according to the present invention includes means for rotating the yarn feeding bobbin at a high speed in the direction opposite to the winding direction around the axis. By this rotational drive means, the yarn is actively unwound from the yarn feeding bobbin, so that fluctuations in the tension of the yarn due to high-speed unwinding are remarkably reduced. The occurrence of fuzzing and the like can be almost eliminated.

以下、添付図面に基づいて、本発明に係る自動ワインダーについて詳細に説明する。   Hereinafter, based on an accompanying drawing, an automatic winder concerning the present invention is explained in detail.

図１は、本発明に係る自動ワインダーを示す正面図である。自動ワインダーは、多数並設された巻取りユニット１と、各巻取りユニット１，１・・・を制御するための制御装置１０とを備えている。巻取りユニット１は、リング精紡機等で生産された給糸ボビン３と、給糸ボビン３からの紡績糸Ｙを巻き返して形成したパッケージ４とを備えている。   FIG. 1 is a front view showing an automatic winder according to the present invention. The automatic winder includes a plurality of winding units 1 and a control device 10 for controlling the winding units 1, 1. The winding unit 1 includes a yarn supplying bobbin 3 produced by a ring spinning machine or the like, and a package 4 formed by winding the spun yarn Y from the yarn supplying bobbin 3.

パッケージ４は、綾振りドラム５に接触接圧している。綾振りドラム５は、モータ等（図示略）により回転駆動し、この綾振りドラム５の回転駆動に追従してパッケージ４が回転する。綾振りドラム５の回転速度は、制御装置１０によって制御される。綾振りドラム５は、給糸ボビン３からの糸Ｙを案内してトラバース（綾振り）するための溝５ａが設けられている。巻取りユニット１は、綾振りドラム５を回転駆動させることにより、給糸ボビン３からの糸Ｙをトラバースしながら解舒してパッケージ４に巻き返す。その際、糸Ｙは解舒バルーンを安定にするヤーンガイド２０及び巻取りテンションを制御するテンション装置２１を通過する。   The package 4 is in contact contact pressure with the traverse drum 5. The traverse drum 5 is rotationally driven by a motor or the like (not shown), and the package 4 rotates following the rotational drive of the traverse drum 5. The rotational speed of the traverse drum 5 is controlled by the control device 10. The traverse drum 5 is provided with a groove 5a for guiding and traversing the yarn Y from the yarn feeding bobbin 3. The winding unit 1 rotates the traverse drum 5 to unwind the yarn Y from the yarn feeding bobbin 3 while traversing and wind it back around the package 4. In doing so, the yarn Y passes through a yarn guide 20 that stabilizes the unraveling balloon and a tension device 21 that controls the winding tension.

巻取りユニット１は、給糸ボビン３とパッケージ４との間に、糸継ぎ手段３０を備えている。糸継ぎ手段３０は、スプライサー等の糸継ぎ装置３１と、パッケージ４側の上糸を糸継ぎ装置３１へ案内するサクションマウス３２と、給糸ボビン３側の下糸を糸継ぎ装置３１へ案内するサクションパイプ３３とを備えている。巻取りユニット１は、走行糸Ｙにおけるスラブ等の糸欠点を検出してカットするクリアラー３５を備えている。糸継ぎ手段３０及びクリアラー３５は制御装置１０に接続されており、クリアラー３５が糸欠点を検出してカットした後に、糸継ぎ手段３０が上糸と下糸を繋いで巻取りを再開する。   The winding unit 1 includes a yarn splicing means 30 between the yarn supplying bobbin 3 and the package 4. The yarn joining means 30 guides the yarn joining device 31 such as a splicer, a suction mouth 32 for guiding the upper yarn on the package 4 side to the yarn joining device 31, and the lower yarn on the yarn feeding bobbin 3 to the yarn joining device 31. And a suction pipe 33. The winding unit 1 includes a clearer 35 that detects and cuts a yarn defect such as a slab in the traveling yarn Y. The yarn joining means 30 and the clearer 35 are connected to the control device 10, and after the clearer 35 detects and cuts the yarn defect, the yarn joining means 30 joins the upper yarn and the lower yarn and resumes winding.

巻取りユニット１は、給糸ボビン３を軸芯Ｃを中心に高速回転駆動するための回転駆動手段２を備えている。本例の回転駆動手段２は、モータ２ａの駆動軸２ｂに給糸ボビン３を装着してボビン３を直接的に回転駆動したものであるがベルト等を介して連結駆動してもよい。回転駆動手段２は、給糸ボビン３を糸の解舒方向に回転駆動する。即ち、図２に示すように、回転駆動手段２は、給糸ボビン３に対する糸Ｙの巻き付け方向とは逆方向である糸の解舒方向（図２の例で、糸Ｙが右巻き方向の場合、ボビン３を矢印方向に回転する。従って、糸Ｙが左巻き方向の場合、ボビン３を矢印反対方向に回転する。）に給糸ボビン３を回転駆動することにより、給糸ボビン３から糸Ｙを積極的に解舒する。   The winding unit 1 includes a rotation driving means 2 for driving the yarn feeding bobbin 3 to rotate at high speed around the axis C. The rotational driving means 2 of this example is one in which the yarn feeding bobbin 3 is attached to the driving shaft 2b of the motor 2a and the bobbin 3 is directly rotationally driven, but may be coupled and driven via a belt or the like. The rotation driving means 2 drives the yarn feeding bobbin 3 to rotate in the yarn unwinding direction. That is, as shown in FIG. 2, the rotation driving means 2 has a yarn unwinding direction that is opposite to the winding direction of the yarn Y around the yarn feeding bobbin 3 (in the example of FIG. 2, the yarn Y is in the clockwise direction). In this case, the bobbin 3 is rotated in the direction of the arrow, and therefore when the yarn Y is in the counterclockwise direction, the bobbin 3 is rotated in the direction opposite to the arrow. Y is actively solved.

回転駆動手段２は制御装置１０に接続されており、制御装置１０により給糸ボビン３の回転速度を制御するようになっている。そして、給糸ボビン３の回転速度は、綾振りドラム５の回転速度以上に制御されている。即ち、単位時間当たりに解舒される糸量の方が、単位時間当たりにパッケージに巻き取られる糸量よりも多くなるように（オーバーフィード気味になるように）ドラム５とボビン３の回転速度が制御されている。これにより、高速解舒による給糸ボビン３からの糸Ｙのテンション変動が少なくなり、弱糸切れやスラッフィング切れ、毛羽立ち等の発生が著しく減少する。   The rotation driving means 2 is connected to the control device 10, and the rotation speed of the yarn feeding bobbin 3 is controlled by the control device 10. The rotational speed of the yarn feeding bobbin 3 is controlled to be higher than the rotational speed of the traverse drum 5. That is, the rotational speeds of the drum 5 and the bobbin 3 so that the amount of yarn unwound per unit time is larger than the amount of yarn wound around the package per unit time (so as to feel overfeed). Is controlled. Thereby, the tension fluctuation of the yarn Y from the yarn feeding bobbin 3 due to high-speed unwinding is reduced, and the occurrence of weak yarn breakage, sluffing breakage, fluffing, etc. is remarkably reduced.

別の実施例では、巻取りユニット１は、給糸ボビン３の残糸を検出するための検出手段６を備えている。検出手段６は距離センサーからなっている。距離センサー６は制御装置１０に接続されている。距離センサー６は、給糸ボビン３の下端から所定の位置（長さの約１／３）に設けられている。糸Ｙの解舒張力は、給糸ボビン３の残糸によって変化する。特に、三分玉と呼ばれる給糸ボビン３の残糸量が１／３となった時から解舒張力が急激に増加して、糸切れやスラッフィングの発生が非常に多くなる。   In another embodiment, the winding unit 1 includes detection means 6 for detecting the remaining yarn of the yarn supplying bobbin 3. The detection means 6 is a distance sensor. The distance sensor 6 is connected to the control device 10. The distance sensor 6 is provided at a predetermined position (about １ ／ of the length) from the lower end of the yarn feeding bobbin 3. The unwinding tension of the yarn Y varies depending on the remaining yarn of the yarn supplying bobbin 3. In particular, the unwinding tension increases abruptly from the time when the remaining yarn amount of the yarn feeding bobbin 3, which is called a triple ball, becomes 1/3, and the occurrence of yarn breakage and sluffing is extremely increased.

距離センサー６は、所定位置における給糸ボビン３までの距離を常時検知している。距離センサー６が距離の変化を検出することにより、給糸ボビン３の残糸量が１／３になったことを判別する。そして、制御装置１０は、巻き始めでは回転駆動手段２を停止しておき、距離センサー６の検出により、回転駆動手段２を駆動して給糸ボビン３を高速回転し、スラッフィング等を防止することもできる。検出手段６は、糸Ｙの重さを検出することにより残糸量を判別する重量センサーでもよい。また、給糸ボビン３の残糸量に応じて給糸ボビン３の回転速度を変化させ、テンション変動を補正するようにしてもよい。   The distance sensor 6 constantly detects the distance to the yarn feeding bobbin 3 at a predetermined position. When the distance sensor 6 detects the change in distance, it is determined that the remaining yarn amount of the yarn supplying bobbin 3 has become １ ／. Then, the control device 10 stops the rotation driving means 2 at the start of winding, and drives the rotation driving means 2 to rotate the yarn feeding bobbin 3 at a high speed by detection of the distance sensor 6 to prevent sluffing and the like. You can also. The detection means 6 may be a weight sensor that determines the remaining yarn amount by detecting the weight of the yarn Y. Alternatively, the tension fluctuation may be corrected by changing the rotational speed of the yarn supplying bobbin 3 in accordance with the remaining yarn amount of the yarn supplying bobbin 3.
