Description

本発明は、巻取装置に適用されて、給糸ボビンからの解舒作業に際して生じた風綿を吸引回収する風綿回収装置に関する。本発明における巻取装置とは、自動ワインダー装置などを意味する。   The present invention relates to a fluff collecting device that is applied to a winding device and sucks and collects fluff produced during unwinding work from a yarn feeding bobbin. The winding device in the present invention means an automatic winder device or the like.

この種の風綿回収装置の従来例としては、例えば特許文献１を挙げることができる。そこでは、解舒作業の進行に伴って下降変位されるバルーン規制部材に風綿回収機能を付与している。具体的には、バルーン規制部材を内管と外管とで構成されて、内流路と外流路とを有する二重管構造とし、両流路を区画する内管の筒壁に、風綿吸引用の開口を設けている。内管の下部から吸い込まれた風綿は、開口を介して外流路に至り、外流路に連通された吸引パイプから集綿ボックスに送られる。糸ボビンから解舒された糸は、バルーンを形成したのち、内管内部の内流路を通って下流側に搬送される。   As a conventional example of this type of fluff collecting device, for example, Patent Document 1 can be cited. There, a fluff collection function is given to a balloon regulating member that is displaced downward as the unwinding operation proceeds. Specifically, the balloon regulating member is composed of an inner tube and an outer tube, and has a double tube structure having an inner channel and an outer channel. An opening for suction is provided. The fluff sucked from the lower part of the inner pipe reaches the outer flow path through the opening, and is sent to the cotton collection box from the suction pipe connected to the outer flow path. The yarn unwound from the yarn bobbin forms a balloon and then is conveyed downstream through the inner flow path inside the inner tube.

特開平５−１３９６２１号公報（図２、図５参照）Japanese Patent Laid-Open No. 5-139621 (see FIGS. 2 and 5)

特許文献１の風綿回収装置の問題は、給糸ボビンの真上で風綿を回収するため、給糸ボビンから水平方向に広がるバルーン形態で解舒された糸に付着の風綿に対する回収効率が悪く、風綿が周囲に飛散しやすい点にある。   The problem with the fluff collecting device of Patent Document 1 is that the fluff is collected just above the yarn feeding bobbin, so the collection efficiency for the fluff adhering to the yarn unraveled in a balloon form spreading horizontally from the yarn feeding bobbin. However, there is a tendency for the fluff to be scattered around.

本発明の目的は、バルーン形態で解除された糸に付着の風綿に対しても優れた風綿回収能力を発揮し、したがって、風綿をより効率的に回収することができる風綿回収装置を得ることにある。   An object of the present invention is to provide a cotton-collecting device that exhibits excellent cotton-collecting ability even with respect to the cotton-fouling attached to the thread released in the form of a balloon, and thus can collect the cotton-floss more efficiently. There is in getting.

本発明は、巻取装置に適用されて、給糸ボビンからの解舒作業に際して生じた風綿を吸引回収する風綿回収装置を対象とする。この風綿回収装置は、風綿を吸引回収する吸引開口部を備えた吸引ノズルと、該吸引ノズルを昇降変位させる昇降手段とを備える。前記巻取装置は解舒補助装置を備え、該解舒補助装置は、前記給糸ボビンの解舒作業の進行に追随して下降しつつ、バルーンの大きさを規制するバルーン規制部材を備える。前記バルーン規制部材は、上下に開口を有する筒体からなり、前記給糸ボビンの解舒位置の上方に位置する。そして、前記給糸ボビンの解舒位置、および前記給糸ボビンの解舒位置と前記バルーン規制部材の下側開口との間に形成されたバルーンに対して前記吸引ノズルの吸引開口部が臨むように、前記給糸ボビンからの解舒作業の進行に追随させて、前記昇降手段により該吸引ノズルが下降変位されるように構成されていることを特徴とする。 The present invention is directed to a fluff collecting device that is applied to a winding device and sucks and collects fluff produced during unwinding work from a yarn feeding bobbin. The fluff collecting device includes a suction nozzle having a suction opening for sucking and collecting fluff, and an elevating means for moving the suction nozzle up and down. The winding device includes an unwinding assisting device, and the unwinding assisting device includes a balloon regulating member that regulates the size of the balloon while descending following the progress of the unwinding operation of the yarn feeding bobbin. The balloon regulating member is made of a cylindrical body having an opening in the top and bottom, you located above the unwinding position of the yarn supplying bobbin. The unwinding position of the yarn supplying bobbin, and the yarn supplying bobbin unwinding position and the like of the suction opening of the suction nozzle faces relative to the balloon which is formed between the lower opening of the balloon regulating member Further, the suction nozzle is configured to be displaced downward by the lifting / lowering means in accordance with the progress of the unwinding operation from the yarn feeding bobbin.

前記吸引ノズルが、前記解舒補助装置のバルーン規制部材から離間して配置されている形態を採ることができる。 Before Symbol suction nozzle may take the form as it is spaced from the balloon regulating member of the unwinding assisting device.

前記吸引ノズルが前記解舒補助装置の可動部に連結されており、該可動部による前記バルーン規制部材の下降操作に伴って、該吸引ノズルが下降変位されるようにすることができる。   The suction nozzle is connected to a movable part of the unwinding assisting device, and the suction nozzle can be displaced downward as the balloon restriction member is lowered by the movable part.

前記吸引ノズルの吸引開口部は、水平方向に長い横長形状に形成されており、前記吸引開口部の水平方向の横幅寸法が、給糸ボビンのボビン幅よりも大きく設定されている形態を採ることができる。ここでいう「給糸ボビンのボビン幅」とは、糸が巻かれた状態の給糸ボビンＢの最大直径を意味する。さらに、前記吸引ノズルの吸引開口部の水平方向の横幅寸法が、前記給糸ボビンの長手方向に直交する方向のバルーン直径で規定されるバルーン領域より大きく設定されている形態を採ることができる。 The suction opening of the suction nozzle is formed in a horizontally long shape that is long in the horizontal direction, and the horizontal width dimension of the suction opening is set larger than the bobbin width of the yarn feeding bobbin. Can do. Here, the “bobbin width of the yarn feeding bobbin” means the maximum diameter of the yarn feeding bobbin B in a state where the yarn is wound. Furthermore, the horizontal width dimension of the suction opening of the suction nozzle may be set larger than the balloon region defined by the balloon diameter in the direction orthogonal to the longitudinal direction of the yarn feeding bobbin.

吸引ノズルから集綿ボックスに至るダクトが、伸縮自在なフレキシブル管を備えている形態を採ることができる。   The duct from the suction nozzle to the cotton collection box can take a form including a flexible tube that can be expanded and contracted.

本発明においては、給糸ボビンの解舒位置および解舒された糸がバルーンを形成するバルーン形成領域に対して吸引ノズルの吸引開口部が臨むように、給糸ボビンからの解舒作業の進行に追随させて、昇降手段により吸引ノズルが下降変位されるように構成したので、吸引ノズルの姿勢位置が固定されている形態に比べて風綿を効率的に回収することができる。
詳しくは、風綿は、給糸ボビンから解舒された糸と、巻芯上の糸層との接触によって発生するものであり、したがって解舒位置で発生しやすい。また、解舒位置は、給糸ボビンからの解舒作業の進行に伴って下がっていくものである。そこで、本発明のように、給糸ボビンの解舒位置に対して吸引開口部が臨むように、解舒作業の進行に追随させて、吸引ノズルを下降変位させていると、常に最適位置に吸引ノズルを位置させて、風綿を効率的に回収することができる。
また、バルーン形成領域に対して吸引開口部が臨むように、吸引ノズルを下降変位させるので、バルーン形態で解舒された糸に付着している風綿を、効率的に吸引開口部から回収することができる。したがって、風綿が周囲に飛散することを防ぐことができる。 In the present invention, the unwinding operation from the yarn supplying bobbin proceeds so that the unwinding position of the yarn supplying bobbin and the suction opening of the suction nozzle face the balloon forming region where the unwinded yarn forms the balloon. Since the suction nozzle is configured to be displaced downward by the lifting and lowering means, the fluff can be collected more efficiently than in the case where the posture position of the suction nozzle is fixed.
Specifically, the fluff is generated by the contact between the yarn unwound from the yarn supplying bobbin and the yarn layer on the winding core, and is therefore likely to be generated at the unwinding position. Further, the unwinding position is lowered as the unwinding operation from the yarn feeding bobbin progresses. Therefore, as in the present invention, if the suction nozzle is moved downward so that the suction opening faces the unwinding position of the yarn feeding bobbin and the suction nozzle is displaced downward, the optimum position is always maintained. By positioning the suction nozzle, it is possible to efficiently collect the fluff.
Further, since the suction nozzle is moved downward so that the suction opening faces the balloon forming region, the fluff attached to the yarn unwound in the form of a balloon is efficiently recovered from the suction opening. be able to. Accordingly, it is possible to prevent the fluff from being scattered around.

吸引ノズルをバルーン規制部材から離間して配置していると、特許文献１のように、バルーン規制部材内に吸引ノズルを設ける形態に比べて、糸が風綿回収用の吸引ノズルに吸い込まれるおそれが少なく、適性且つ円滑に給糸ボビンからの糸の解舒作業を行うことができる。   When the suction nozzle is arranged away from the balloon regulating member, the thread may be sucked into the suction nozzle for collecting the fluff as compared with the case where the suction nozzle is provided in the balloon regulating member as in Patent Document 1. Therefore, the yarn can be unwound from the yarn feeding bobbin appropriately and smoothly.

吸引ノズルが解舒補助装置の可動部に固定されており、該可動部によるバルーン規制部材の下降操作に伴って、該吸引ノズルが下降変位されるように構成されていると、実質的に解舒補助装置の可動部を昇降手段として、吸引ノズルを下降変位させることができる。これによれば、解舒補助装置の可動部とは別に昇降手段を備える形態に比べて、部品点数の削減化と制御機構の簡素化を図ることができるので、風綿回収装置を設けたことに伴う巻取装置の製造コストの上昇を抑えることができる。   If the suction nozzle is fixed to the movable part of the unwinding assisting device, and the suction nozzle is configured to be displaced downward in accordance with the lowering operation of the balloon regulating member by the movable part, it is substantially solved. The suction nozzle can be displaced downward using the movable part of the scissors assisting device as the lifting means. According to this, since the number of parts can be reduced and the control mechanism can be simplified as compared with the form provided with the lifting means separately from the movable part of the unwinding assisting device, the fluff collecting device is provided. An increase in the manufacturing cost of the winding device associated with can be suppressed.

吸引ノズルを水平方向に長い横長形状に形成していると、給糸ボビンの解除位置に対峙するように吸引ノズルを配置することができるので、当該解舒位置で発生した風綿を効率的に吸収することができる。また、吸引ノズルの水平方向の横幅寸法を給糸ボビンのボビン幅よりも大きく設定していると、給糸ボビンからバルーンとなって解舒される糸に付着の風綿を効率的に回収することができる。   If the suction nozzle is formed in a horizontally long shape in the horizontal direction, the suction nozzle can be arranged so as to face the release position of the yarn feeding bobbin, so that the fluff generated at the unwinding position can be efficiently removed. Can be absorbed. Also, if the horizontal width dimension of the suction nozzle is set to be larger than the bobbin width of the yarn feeding bobbin, the fluff adhering to the yarn to be unwound as a balloon from the yarn feeding bobbin is efficiently collected. be able to.

吸引ノズルから集綿ボックスに至るダクトが、伸縮自在なフレキシブル管を備えるものとしていると、吸引ノズルを昇降変位させることに伴うダクト長の変動をフレキシブル管で吸収することができるので、ダクトの構成を簡素化して、昇降変位可能な吸引ノズルを備える風綿回収装置を設けたことに伴う巻取装置の製造コストの上昇を抑えることができる。   If the duct from the suction nozzle to the cotton collection box is provided with a flexible tube that can be expanded and contracted, fluctuations in the duct length caused by moving the suction nozzle up and down can be absorbed by the flexible tube. The increase in the manufacturing cost of the winding device due to the provision of the fluff collecting device provided with the suction nozzle that can be displaced up and down can be suppressed.

図１ないし図５に、本発明に係る風綿回収装置を自動ワインダー（巻取装置）に適用した実施形態を示す。自動ワインダー装置は、列状に配置した一群のワインディングユニットで構成されている。図２において、ワインディングユニットは、起立固定される縦長箱状のユニットフレーム１を基体にして構成する。ユニットフレーム１の一側には、解舒補助装置２と、テンション装置３と、糸継ぎ装置４と、スラブキャッチャー５などが、フレーム下部からフレーム上部へ向かって記載順に配置してある。ユニットフレーム１の一側上部には、糸Ｙを一定の幅範囲で変位操作（トラバース）する綾振ドラム６と、綾振ドラム６のトラバース領域に臨んで配置されるガイド板７と、パッケージＰを回転自在に軸支するクレードル９などが配置してある。これらの機器以外に、切断された糸を吸引捕捉して糸継ぎ装置４に渡す中継ぎパイプ１０とサクションマウス１１が、先の機器列の中途部に上下方向へ旋回可能に設けられている。   1 to 5 show an embodiment in which the fluff collecting device according to the present invention is applied to an automatic winder (winding device). The automatic winder device is composed of a group of winding units arranged in a line. In FIG. 2, the winding unit is configured with a vertically long box-shaped unit frame 1 fixed upright as a base. On one side of the unit frame 1, an unwinding assisting device 2, a tension device 3, a yarn splicing device 4, a slab catcher 5 and the like are arranged in the order of description from the lower part of the frame toward the upper part of the frame. A traverse drum 6 that displaces (traverses) the yarn Y within a certain width range, a guide plate 7 that faces the traverse region of the traverse drum 6, and a package P A cradle 9 or the like that rotatably supports the shaft is disposed. In addition to these devices, a splicing pipe 10 and a suction mouth 11 that suck and capture the cut yarn and pass it to the yarn splicing device 4 are provided in the middle of the previous device row so as to be able to turn in the vertical direction.

解舒補助装置２の下方には、給糸ボビンＢが起立姿勢で支持されている。給糸ボビンＢからバルーン１３の形態で繰り出された糸Ｙは、先の各機器２〜５を通過する間に糸欠陥の有無がチェックされ、糸欠陥が発見されるとスラブキャッチャー５に設けたカッターと、テンション装置３に設けたカッターで切断されて、欠陥部が吸引除去される。   Below the unwinding assisting device 2, the yarn supplying bobbin B is supported in an upright posture. The yarn Y fed out in the form of the balloon 13 from the yarn feeding bobbin B is checked for the presence or absence of a yarn defect while passing through the respective devices 2 to 5, and provided in the slab catcher 5 when a yarn defect is found. The defective part is sucked and removed by cutting with a cutter and a cutter provided in the tension device 3.

図１および図３に示すように、解舒補助装置２は、バルーンの大きさを規制するためのバルーン規制部材である可動筒体からなるバルーンガイド２０と、バルーンガイド２０の上部に配された固定筒体２１と、バルーンガイド２０を昇降変位させるための可動部としてシリンダ２２などを備えている。バルーンガイド２０は、上下に開口を有する円筒体であり、固定筒体２１の外周に遊嵌されている。バルーンガイド２０の外周には、左右一対の覆い部２３・２３が固定され、これら覆い部２３・２３がシリンダ２２のピストンロッド２４により上下動される支持腕２５に組み付けられている。したがって、シリンダ２２のピストンロッド２４の伸縮に応じてバルーンガイド２０は昇降変位する。   As shown in FIGS. 1 and 3, the unwinding assisting device 2 is arranged on a balloon guide 20 composed of a movable cylinder that is a balloon regulating member for regulating the size of the balloon, and an upper portion of the balloon guide 20. A cylinder 22 is provided as a movable part for moving the fixed cylinder 21 and the balloon guide 20 up and down. The balloon guide 20 is a cylindrical body having openings at the top and bottom, and is loosely fitted on the outer periphery of the fixed cylinder body 21. A pair of left and right cover parts 23, 23 are fixed to the outer periphery of the balloon guide 20, and these cover parts 23, 23 are assembled to a support arm 25 that is moved up and down by the piston rod 24 of the cylinder 22. Therefore, the balloon guide 20 is displaced up and down in accordance with the expansion and contraction of the piston rod 24 of the cylinder 22.

各覆い部２３・２３は、支持腕２５から水平方向に延びる翼部２６と、翼部２６の先端から下方に延びる腕部２７からなる。各腕部２７の遊端の内面には、給糸ボビンＢの解舒位置２９であるチェース部３０を検出するためのセンサ３１が配設されている。センサ３１は、投光素子と受光素子とからなる透過型のセンサであり、給糸ボビンＢをワインディングユニットにセットした初期状態においては、投光素子からの照射光はチェース部３０で遮られて受光は検出されず、コントローラ３２はオフ信号を受けるようになっている。初期状態から解舒作業が進み、チェース部３０が下降すると、受光素子による受光量が増えて、受光素子はオン信号を発する。かかる受光素子からのオン信号を受けると、コントローラ３２はシリンダ２２のピストンロッド２４を伸長させて、覆い部２３・２３を下降させる。投光素子からの照射光がチェース部３０で遮られて受光素子がオフ信号を発すると、コントローラ３２はシリンダ２２のピストンロッド２４の伸長を停止させる。以上のようなピストンロッド２４の伸長動作を繰り返すことにより、バルーンガイド２０を、覆い部２３・２３と共に順次下降変位させることができる。   Each of the cover parts 23 and 23 includes a wing part 26 extending in the horizontal direction from the support arm 25 and an arm part 27 extending downward from the tip of the wing part 26. A sensor 31 for detecting the chase portion 30 that is the unwinding position 29 of the yarn feeding bobbin B is disposed on the inner surface of the free end of each arm portion 27. The sensor 31 is a transmission type sensor composed of a light projecting element and a light receiving element. In an initial state where the yarn feeding bobbin B is set in the winding unit, the irradiation light from the light projecting element is blocked by the chase portion 30. No light is detected, and the controller 32 receives an off signal. When the unwinding operation proceeds from the initial state and the chase portion 30 is lowered, the amount of light received by the light receiving element increases, and the light receiving element emits an ON signal. When receiving the ON signal from the light receiving element, the controller 32 extends the piston rod 24 of the cylinder 22 and lowers the cover portions 23 and 23. When the irradiation light from the light projecting element is blocked by the chase portion 30 and the light receiving element emits an off signal, the controller 32 stops the extension of the piston rod 24 of the cylinder 22. By repeating the extension operation of the piston rod 24 as described above, the balloon guide 20 can be sequentially displaced downward together with the cover portions 23 and 23.

図１および図３において、符号３５は、給糸ボビンＢからの解舒作業に際して生じた風綿を吸収回収する風綿回収装置の吸引ノズルを示す。図５に示すように、この吸引ノズル３５は、給糸ボビンＢに対峙するように前方に指向する左右横長の主面壁３６と、主面壁３６の上端から連設された上壁３７と、主面壁３６の左右端部において、該主面壁３６と上壁３７とを繋ぐ側壁３８とを有し、所定の間隔寸法を置いてバルーンガイド２０の後方位置に離間して配置されている。これら主面壁３６、上壁３７、左右端部の側壁３８により、給糸ボビンＢ側に指向・開口する吸引開口部４２が形成されている。
上壁３７の左右中央部には、吸引口３９が開設されており、該吸引口３９には円筒形のダクト４０が連設されている。上壁３７は、吸引口３９を有する中央壁３７ａと、該中央壁３７ａの両端部から左右方向に向かって下り傾斜する一対の傾斜壁３７ｂとで構成される。 In FIG. 1 and FIG. 3, the code | symbol 35 shows the suction nozzle of the fluff collection apparatus which absorbs and collects the fluff produced in the unwinding operation | work from the yarn feeding bobbin B. FIG. As shown in FIG. 5, the suction nozzle 35 includes a horizontally long main surface wall 36 that is directed forward so as to face the yarn feeding bobbin B, an upper wall 37 that is provided continuously from the upper end of the main surface wall 36, At the left and right ends of the face wall 36, the side wall 38 that connects the main face wall 36 and the upper wall 37 is provided, and is spaced apart from the rear position of the balloon guide 20 with a predetermined spacing dimension. The main surface wall 36, the upper wall 37, and the side walls 38 at the left and right ends form a suction opening 42 that is directed and opened toward the yarn feeding bobbin B.
A suction port 39 is formed in the left and right central portion of the upper wall 37, and a cylindrical duct 40 is connected to the suction port 39. The upper wall 37 includes a central wall 37a having a suction port 39, and a pair of inclined walls 37b that are inclined downward from both ends of the central wall 37a in the left-right direction.

図１に示すように、吸引ノズル３５は、上壁３７の左右中央部の前端部に設けられた連結片４１を介して支持腕２５に装着されている。したがって、解舒補助装置２の可動部であるシリンダ２２によるバルーンガイド２０の下降操作により、吸引ノズル３５も下降変位される。換言すれば、吸引ノズル３５を昇降変位させる昇降手段は、解舒補助装置２の可動部と共用部品化されている。
このように、バルーンガイド２０の下降操作に伴って吸引ノズル３５が下降変位されるように構成していると、給糸ボビンＢの解舒位置２９に対して吸引開口部４２が臨むように、解舒作業の進行に追随させて、吸引ノズル３５を下降変位させることができる。 As shown in FIG. 1, the suction nozzle 35 is attached to the support arm 25 via a connecting piece 41 provided at the front end of the left and right central portion of the upper wall 37. Accordingly, the suction nozzle 35 is also displaced downward by the lowering operation of the balloon guide 20 by the cylinder 22 which is the movable part of the unwinding assisting device 2. In other words, the lifting means for moving the suction nozzle 35 up and down is shared with the movable part of the unwinding assisting device 2.
In this way, when the suction nozzle 35 is configured to be displaced downward as the balloon guide 20 is lowered, the suction opening 42 faces the unwinding position 29 of the yarn feeding bobbin B. The suction nozzle 35 can be displaced downward in accordance with the progress of the unwinding operation.

図１および図４に示すように、ダクト４０は、吸引ノズル３５に連結された下ダクト４０ａと、集綿ボックスに至る上ダクト４０ｂと、これら上下ダクト４０ａ・４０ｂの間に配設された伸縮自在なフレキシブル管４０ｃとを備える。フレキシブル管４０ｃが伸縮することで、吸引ノズル３５の下降変位に伴うダクト長の長さ変動を吸収することができる。   As shown in FIGS. 1 and 4, the duct 40 includes a lower duct 40a connected to the suction nozzle 35, an upper duct 40b reaching the cotton collection box, and an expansion / contraction disposed between the upper and lower ducts 40a and 40b. And a flexible tube 40c. By expanding and contracting the flexible tube 40c, the length variation of the duct length accompanying the downward displacement of the suction nozzle 35 can be absorbed.

以上のような構成からなる風綿回収装置によれば、吸引ノズル３５をバルーンガイド２０から離間して配置したので、特許文献１のように、糸の接触位置で風綿の吸引動作を行う形態に比べて、糸Ｙが吸引ノズル３５に不用意に吸い込まれるおそれが少なく、適性且つ円滑に給糸ボビンＢからの糸Ｙの解舒作業を行うことができる。   According to the fluff collecting apparatus having the above-described configuration, the suction nozzle 35 is disposed away from the balloon guide 20, so that the fluff sucking operation is performed at the yarn contact position as in Patent Document 1. As compared with the above, the yarn Y is less likely to be inadvertently sucked into the suction nozzle 35, and the unwinding operation of the yarn Y from the yarn feeding bobbin B can be performed appropriately and smoothly.

何よりも、給糸ボビンＢの解舒位置２９に対して吸引開口部４２が臨むように、給糸ボビンＢからの解舒作業の進行に追随させて、吸引ノズル３５を下降変位させるようにしたので、吸引ノズル３５の姿勢位置が固定されている形態に比べて風綿を効率的に回収することができる。つまり、風綿の発生源である解舒位置２９の近くで吸引作業を行うことができるので、風綿を効率的に吸収することができることができる点で優れている。
また、バルーン形態で給糸ボビンＢから繰り出された糸Ｙに風綿が付着していると、風綿が周囲に飛散しやすいが、本実施形態のように、幅広の吸引ノズル３５の吸引開口部４２によりバルーンまわりの空気に対して吸引動作を行うようにしていると、風綿が周囲に飛散することを確実に防ぐことができる。 Above all, the suction nozzle 35 is displaced downward in accordance with the progress of the unwinding operation from the yarn supplying bobbin B so that the suction opening 42 faces the unwinding position 29 of the yarn supplying bobbin B. Therefore, the fluff can be collected more efficiently than in the case where the posture position of the suction nozzle 35 is fixed. That is, the suction operation can be performed near the unwinding position 29 that is the generation source of the fluff, which is excellent in that the fluff can be absorbed efficiently.
Further, if the fluff is attached to the yarn Y fed out from the yarn feeding bobbin B in a balloon form, the fluff is likely to scatter around. However, as in this embodiment, the suction opening of the wide suction nozzle 35 is used. If the suction operation is performed on the air around the balloon by the portion 42, it is possible to reliably prevent the fluff from being scattered around.

吸引ノズル３５をバルーンガイド２０を支持する支持腕２５に連結して、シリンダ２２によるバルーンガイド２０の下降操作に伴って、吸引ノズル３５も下降変位されるように構成したので、これら吸引ノズル３５およびバルーンガイド２０を下降操作するための駆動機構を別々に備える形態に比べて、部品点数の削減化と制御機構の簡素化を図ることができる。したがって、風綿回収装置を設けたことに伴う自動ワインダーの製造コストの上昇を効果的に抑えることができる。   The suction nozzle 35 is connected to the support arm 25 that supports the balloon guide 20, and the suction nozzle 35 is also moved downward as the balloon guide 20 is lowered by the cylinder 22. Compared with a configuration in which a drive mechanism for lowering the balloon guide 20 is separately provided, the number of parts can be reduced and the control mechanism can be simplified. Therefore, an increase in the manufacturing cost of the automatic winder associated with the provision of the fluff collecting device can be effectively suppressed.

吸引ノズル３５の吸引開口部４２を水平方向に長い横長形状に形成していると、給糸ボビンＢの解除位置２９に対峙するように吸引ノズル３５を配置することができるので、当該解舒位置２９で発生した風綿を効率的に吸収することができる。また、吸引開口部４２の水平方向の横幅寸法を給糸ボビンＢのボビン幅（糸が巻かれた状態の給糸ボビンＢの最大直径）よりも大きく設定していると、給糸ボビンＢからバルーン１３となって解舒される糸Ｙに付着の風綿を効率的に回収することができる。
さらに、吸引開口部４２の水平方向の横幅寸法を、バルーン形態で給糸ボビンＢから繰り出された糸Ｙのバルーン領域（ボビンＢの長手方向に直交する方向のバルーン直径）より大きくしたので、バルーン形態で旋回されながら繰り出される糸Ｙのバルーン領域の全域から発生する風綿を回収することができる。 If the suction opening 42 of the suction nozzle 35 is formed in a horizontally long shape in the horizontal direction, the suction nozzle 35 can be disposed so as to face the release position 29 of the yarn feeding bobbin B. The fluff generated in 29 can be efficiently absorbed. If the horizontal width dimension of the suction opening 42 is set to be larger than the bobbin width of the yarn feeding bobbin B (the maximum diameter of the yarn feeding bobbin B in a state where the yarn is wound), the yarn feeding bobbin B The fluff adhering to the yarn Y to be unwound as the balloon 13 can be efficiently recovered.
Furthermore, since the horizontal width dimension of the suction opening 42 in the horizontal direction is larger than the balloon region of the yarn Y fed out from the yarn feeding bobbin B in a balloon form (the balloon diameter in the direction perpendicular to the longitudinal direction of the bobbin B), the balloon The fluff generated from the entire balloon region of the yarn Y that is fed while being swung in the form can be collected.

吸引ノズル３５から集綿ボックスに至るダクト４０を、伸縮自在なフレキシブル管４０ｃを備えるものとしたので、吸引ノズル３５を昇降変位させることに伴うダクト長の変動をフレキシブル管４０ｃで吸収することができる。これによれば、昇降変位可能な吸引ノズル３５を備える風綿回収装置を設けたことに伴う自動ワインダーの製造コストの上昇を抑えることができる。   Since the duct 40 extending from the suction nozzle 35 to the cotton collection box is provided with the flexible tube 40c that can be expanded and contracted, the flexible tube 40c can absorb the change in the duct length that accompanies the up-and-down displacement of the suction nozzle 35. . According to this, it is possible to suppress an increase in the manufacturing cost of the automatic winder due to the provision of the fluff collecting device including the suction nozzle 35 that can be displaced up and down.

図６（ａ）・（ｂ）に、吸引ノズル３５の別実施形態を示す。図６に示す吸引ノズル３５では、ダクト４０（下ダクト４０ａ）と吸引ノズル３５との連結部４５を、下方に行くに従って漸次径寸法が大きくなる下広がり状に形成し、幅方向に広い吸収開口４２を形成している点が相違する。それ以外の点は、先の図５に示す形態と同様である。   FIGS. 6A and 6B show another embodiment of the suction nozzle 35. In the suction nozzle 35 shown in FIG. 6, the connecting portion 45 between the duct 40 (lower duct 40a) and the suction nozzle 35 is formed in a downwardly expanding shape in which the diameter gradually increases as it goes downward, and the absorption opening is wide in the width direction. The difference is that 42 is formed. Other points are the same as in the embodiment shown in FIG.

図６（ａ）・（ｂ）に示す吸引ノズル３５によれば、先の図５に示す吸引ノズル３５の形状に比べて、吸引ノズル３５における吸引開口部４２の幅方向の広い範囲で大きな吸引流を得ることができるので、該吸引ノズル３５による吸引効率が向上する。   According to the suction nozzle 35 shown in FIGS. 6A and 6B, compared with the shape of the suction nozzle 35 shown in FIG. 5, the suction is large in a wide range in the width direction of the suction opening 42 in the suction nozzle 35. Since a flow can be obtained, the suction efficiency by the suction nozzle 35 is improved.

上記実施形態においては、吸引ノズル３５は解舒補助装置２の可動部であるシリンダ２２により昇降変位可能に構成されていたが、本発明はこれに限られず、吸引ノズル３５を昇降変位させるための専用のアクチュエータを備える形態を採ることができる。
また、上記実施形態では、吸引ノズル３５は、バルーンガイド２０の後方寄りに配置されていたが、本発明はこれに限られず、例えばバルーンガイド２０の左右のそれぞれに吸引ノズル３５・３５を配設する形態であってもよい。前後左右の四方に吸引ノズル３５を配置することもできる。
吸引ノズル３５の形態は、上記実施形態に示したものに限られない。 In the above-described embodiment, the suction nozzle 35 is configured to be movable up and down by the cylinder 22 that is a movable part of the unwinding assisting device 2.
