本発明は糸条の巻取装置に装着された空ボビン
に糸条を巻付ける際に用いる糸把持機構の改良に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a yarn gripping mechanism used when winding yarn around an empty bobbin mounted on a yarn winding device.
従来から糸条の巻取装置における糸把持機構と
して種々のものが提案されている。たとえば、糸

下単にボビンという）の表面に、ボビンの軸方向
に糸条をトラバースさせつつ巻取りパツケージを
形成させる際、ボビンを所定の回転数で回転させ
たのち、ボビン端部に設けた切欠や、ブレードカ
ツトといわれる溝、更にはボビンチヤツク等のボ
ビン支持部材と一体的に回転する爪を備えたキヤ
ツチリング等の糸把持部材を用い、これらの切
欠、溝、爪等に糸条供給源から連続して送り出さ
れる糸条の糸端を喰込ませたり、引掛けたりして
ボビンに糸かけし、ボビン表面に糸層を形成させ
つつ巻取を行なうのである。 Various types of yarn gripping mechanisms have been proposed for yarn winding devices. For example, the thread that is continuously sent out from the thread supply device is wound onto the surface of a cylindrical or cylindrical bobbin, drum, cheese, etc. (hereinafter simply referred to as a bobbin) while traversing the thread in the axial direction of the bobbin. When forming a package, after rotating the bobbin at a predetermined number of revolutions, a notch provided at the end of the bobbin, a groove called a blade cut, and a pawl that rotates integrally with the bobbin support member such as a bobbin chuck are provided. Using a thread gripping member such as a catch ring, the end of the thread that is continuously sent out from the thread supply source is bitten or hooked into these notches, grooves, claws, etc., and the thread is threaded onto the bobbin. The winding is performed while forming a yarn layer on the surface of the bobbin.
しかし上記した溝、切欠および爪等の糸把持手
段を用いた従来の糸条の巻取装置では次のような
欠点がある。 However, conventional yarn winding devices using yarn gripping means such as grooves, notches and claws as described above have the following drawbacks.
先ず、ボビンの端部表面にボビン軸とは直角な
方向に部分的な溝を設けたブレードカツトをもつ
ボビンを用いた場合、糸条を確実にブレードカツ
トに把持させるためには回転しているボビンに糸
条を押しつけなければならず、かつ糸かけするた
め、糸道をブレードカツトの溝と一致させる必要
上、操作が面倒な割に成功率が低いという欠点が
ある。 First, when using a bobbin with a blade cut that has partial grooves on the end surface of the bobbin in a direction perpendicular to the bobbin axis, the thread must be rotated to ensure that the thread is gripped by the blade cut. It is necessary to press the thread against the bobbin, and in order to thread the thread, it is necessary to align the thread path with the groove of the blade cut, which has the disadvantage that the success rate is low even though the operation is troublesome.
次にボビンの端面に切欠を設けたボビンを用い
た場合、切欠の狭い部分に糸条を押し込んで糸を
挾持させるための糸条に一時的に高い張力が作用
して糸かけに失敗するという欠点に加え、使用す
るボビンの材質が制限されるという欠点がある。 Next, when using a bobbin with a notch on the end surface of the bobbin, the thread is forced into the narrow part of the notch and a high tension is temporarily applied to the thread to hold the thread, causing failure in threading. In addition to the disadvantages, there is a limitation in the material of the bobbin that can be used.
更に糸かけ爪を有するキヤツチリングや、爪車
のような糸把持部材を用いる場合は、ボビンにブ
レードカツトや切欠を設けた場合にくらべ糸把持
機能にすぐれ、ボビン材質の制限はないものの、
ボビンの端部にバンチ巻を形成しなければならな
いこと、爪車またはキヤツチリング等の糸把持部
材の外周やボビン支持部材のケーシングに糸が巻
付く結果、これらの糸条は満ボビンを玉揚したの
ちに除去しなければならないという欠点がある。 Furthermore, when using a thread gripping member such as a catch ring with a thread hook or a ratchet wheel, the thread gripping function is superior to that when a blade cut or notch is provided on the bobbin, and there are no restrictions on the material of the bobbin.
As a result of having to form a bunch winding at the end of the bobbin and winding the thread around the outer periphery of a thread gripping member such as a ratchet or catch ring or the casing of a bobbin support member, these threads may not be doffed on a full bobbin. The disadvantage is that it must be removed later.
本発明の目的は上記した従来技術の欠陥を改善
し、簡単な構造をもちながらボビン材質の制限も
なく、かつボビン端部にバンチ巻を形成させるこ
となく、簡単な糸かけ操作ができ、かつ尻糸の把
持が確実に行なえる糸把持機構を提供せんとする
ものであある。 The purpose of the present invention is to improve the above-mentioned deficiencies of the prior art, to have a simple structure, to have no restrictions on the bobbin material, and to enable simple threading operations without forming bunch winding at the ends of the bobbin. It is an object of the present invention to provide a thread gripping mechanism that can reliably grip the tail thread.

持続する。 Further, when the thread clamp holding piece 6 shown in FIG.
The outer diameter is preferably slightly larger than the outer diameter of the catch ring 2 and slightly smaller than the inner diameter of the hollow portion 4 of the catch ring 2. However, without being particular about this aspect, the outer diameter of the catch ring 2 is made slightly larger than the hollow part of the catch ring 2, and by pressing the outside, the thin elastic plate is bent, its diameter is reduced, and the elastic plate is attached to the hollow part 4. The elastic plate may be expanded in the hollow portion of the catch ring to bring the elastic plate into close contact with the inner circumferential surface 5 of the catch ring. In this way, when the catch ring 2 is formed into an annular body and the thread clamp holding piece 6 is a thin elastic plate, and this is formed into an annular shape, the thread clamp holding piece 6 is pressed against the inner circumferential surface 5 of the catch ring 2 by the centrifugal force caused by the rotation of the bobbin chuck 1. As a result, both are kept in close contact. While these two are in close contact with each other, a part of the thread that has been threaded is caught between the threads, so that the end thread wound around the bobbin 3 can be securely held while the thread is being wound around the bobbin. It maintains the effect of keeping it in place.

ある。 Further, one or more protrusions 13 protruding outward in the circumferential direction are provided around one side of the thread clamp holding piece 6, and the protrusions 13 are provided on the holding side of the hollow portion 4 of the catch ring 2 as shown in FIG. If the structure is such that it engages with the annular groove 14, it is safe because the thread clamp holding piece 6 will not come out naturally during the rotation of the bobbin 3 and will not fly away.

The thread that has reached this point is further pushed between the inner peripheral surface of the catch ring and the thread holding piece, and reaches the end of the thread introduction notch that extends in the circumferential direction from the base of the claw, where it is stopped and held in the catch ring. It is securely clamped and held by the thread clamping piece pressing the inner peripheral surface. Thereafter, the yarn on the supply side is wound on the surface of the bobbin 3 by the movement of the guide 16, and the yarn on the take-up means side is wound on the surface of the catch ring. The yarn is pulled by the pulling action of both the pulling means and the catch ring, and eventually reaches a tension greater than the cutting strength of the yarn, and is cut, completing the threading. Then, the cut yarn end on the side of the take-off device is taken up by the take-off means. The tail thread, which is the cut end of the thread on the bobbin side, remains firmly pressed and held by the inner circumferential surface 5 of the catch ring and the thread clamping piece 6 throughout the winding process.
