Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、紙製の糸条巻取管の改良に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a yarn winding tube made of paper.
従来、紡績工程、合成繊維の紡糸、延伸撚糸工程等にお
いては、糸を巻き取るため、紙製の糸条巻取管が多用さ
れている。2. Description of the Related Art Conventionally, in a spinning process, a synthetic fiber spinning process, a draw-twisting process, and the like, a paper yarn winding tube is often used to wind a yarn.
係る糸条巻取管は、一般に、マンドレルに厚紙をスパイ
ラル状に幾重にも巻いて形成した糸管の外側に、更に、
表層シートをスパイラル状に巻き付けた後、切断機によ
って所定の長さに切断することにより作製されるが、切
断したままの糸条巻取管では、巻き取った糸条を解除す
る時に、表層シートの端部に糸条が引っ掛かり、糸切れ
や解除ムラが生ずる。Such a yarn winding tube is generally provided on the outside of a yarn tube formed by spirally winding a thick paper around a mandrel,
It is made by winding the surface layer sheet in a spiral shape and then cutting it to a predetermined length with a cutting machine.In a yarn winding tube that has been cut, the surface layer sheet is released when the wound yarn is released. The thread is caught at the end of the thread, causing thread breakage and uneven release.
そこで、第１図のように、糸条巻取管１の端部に断面カ
ール状の湾曲部２を形成したり、或いは、第２図に示す
ように、糸条巻取管１の内壁面端部を切削して薄肉部３
を形成した後、この薄肉部３を内側にカール状に曲げて
カール状の湾曲部２を形成することが行なわれている。Therefore, as shown in FIG. 1, a curved portion 2 having a curled cross section is formed at an end of the yarn winding tube 1, or as shown in FIG. 2, an inner wall surface of the yarn winding tube 1 is formed. Cut the edge and cut the thin part 3
After the formation, the thin portion 3 is bent inward to form a curled curved portion 2.
ところが、図示しない金型によって糸条巻取管１の端部
をカール状に丸めたから糸管を構成している厚紙の各層
間に微細な割れやズレを発生しており、気温や湿度等の
自然環境の変動、或いは、積み重ねて保管している時の
糸条巻取管の自重等によって湾曲部２の曲げ形状や曲率
が不均一になる。However, since the end portion of the yarn winding tube 1 is curled up by a mold (not shown), minute cracks and deviations are generated between the layers of the cardboard that constitutes the yarn tube, and the temperature, humidity, etc. The bending shape and the curvature of the bending portion 2 become non-uniform due to a change in the natural environment, or the weight of the yarn winding tubes when they are stacked and stored.
一方、表層シートの表面には、絞り皺や耳立ちが生じ、
単糸割れ、毛羽立ち、糸切れ等の原因となっている。On the other hand, wrinkles and ears are generated on the surface of the surface layer sheet,
It is a cause of single yarn cracking, fluffing, and yarn breakage.
本考案は、係る従来の欠点を解消するためになされたも
のであり、その目的は、厚紙を巻き重ねた糸管に層間剥
離の原因になる微細な割れやズレが生じないばかりでな
く、表層シートに単糸割れ、毛羽立ち、糸切れ等の原因
になる絞り皺や耳立ちが生じないような糸条巻取管を提
供することにある。The present invention has been made in order to solve the above-mentioned conventional drawbacks, and its purpose is not only to prevent fine cracks and deviations that cause delamination from occurring in the thread tube on which cardboard is wound, but also to use the surface layer. It is an object of the present invention to provide a yarn winding tube in which a sheet is free from wrinkles and ears that cause single yarn cracking, fluffing, and yarn breakage.
すなわち、本考案の糸条巻取管は、糸管の外周面に表層
シートを積層した糸管体からなる糸条巻取管において、
該糸管は厚紙をスパイラル条に幾重にも巻重ねたもので
あり、該糸管体の端部は押圧加工による断面円弧状の円
弧部であり、該表層シートは該円弧部の一部に延出し被
覆して成ることを特徴とするものである。That is, the yarn winding tube of the present invention is a yarn winding tube including a yarn tube body in which a surface layer sheet is laminated on the outer peripheral surface of the yarn tube.
The yarn tube is made by winding cardboard in multiple layers on a spiral strip, the end portion of the yarn tube body is an arc portion having an arc-shaped cross section by pressing, and the surface layer sheet is part of the arc portion. It is characterized in that it is formed by extension coating.
以下、図面により本考案の一実施例を説明する。 An embodiment of the present invention will be described below with reference to the drawings.
第３図（Ｂ）は、本考案に係る糸条巻取管13の要部拡大
断面図であり、糸条巻取管13は、糸管6aの外周面に表層
シート6bを積層した糸管体６から構成されている。FIG. 3 (B) is an enlarged sectional view of an essential part of the yarn winding tube 13 according to the present invention. The yarn winding tube 13 is a yarn tube in which a surface sheet 6b is laminated on the outer peripheral surface of the yarn tube 6a. It is composed of a body 6.
糸管6aは、厚紙をスパイラル状に幾重にも巻重ねること
により形成され、糸管体６の端部は、押圧加工による断
面円弧状に円弧部11になっている。The thread tube 6a is formed by stacking cardboard in a spiral shape in multiple layers, and the end of the thread tube body 6 has an arcuate portion 11 having a circular arc cross section by pressing.
更に、表層シート6bは、その先端部７が糸管体６の先端
部９に至っていないが、糸管体６の先端部９に向けて延
出され、円弧部11の一部を構成するようになっている。Further, although the tip portion 7 of the surface layer sheet 6b does not reach the tip portion 9 of the thread tube body 6, it is extended toward the tip portion 9 of the thread tube body 6 and forms a part of the arc portion 11. It has become.
因みに、上記糸条巻取管の製造方法について説明する。Incidentally, a method for manufacturing the above yarn winding tube will be described.
第３図（Ａ）は、押圧加工前の糸管体端部の断面を示し
ており、糸管体６の端部は、図示しない旋盤等によっ
て、その内外両周縁が切除され、内外両傾斜面8b,8cを
含む断面台形状を呈している。FIG. 3 (A) shows a cross section of the end portion of the thread tube body before pressing, and the end portion of the thread tube body 6 is cut at its inner and outer peripheral edges by a lathe or the like (not shown) to incline both inner and outer sides. It has a trapezoidal cross section including the surfaces 8b and 8c.
次いで、円環状の溝を有し、かつ、溝の断面が円弧状で
ある図示しない金型によって第３図（Ａ）の糸管体６の
端部を押圧すると、第３図（Ｂ）に示すように、糸管体
６の端部が円弧状に圧縮加工され、円弧部11となる。Next, when the end portion of the thread tube body 6 of FIG. 3 (A) is pressed by a mold (not shown) having an annular groove and the cross section of which is arcuate, the result is as shown in FIG. 3 (B). As shown, the end of the thread tube body 6 is compressed into an arc shape to form an arc section 11.
このように、糸管体６の端部の内外両周縁を切除し、糸
管体６の端部を、内外両傾斜面8b,8cを含む台形状とし
た場合には、金型によって圧縮される部分が少ないから
厚紙を巻いて形成した糸管6bの部分に割れやズレが殆ど
発生しない。更に、表層シート6aの部分にも絞り皺や耳
立ちが殆ど発生しない。In this way, when the inner and outer peripheral edges of the end of the thread tube 6 are cut off and the end of the thread tube 6 is formed into a trapezoidal shape including both the inner and outer inclined surfaces 8b and 8c, it is compressed by a mold. Since there are few parts, the thread tube 6b formed by rolling the cardboard is hardly cracked or misaligned. Furthermore, squeezing wrinkles and ears are hardly generated in the surface layer sheet 6a.
なお、糸管体６の一端は、上記のように、押圧加工され
た円弧状の円弧部11を形成するが、他の一端は切断した
ままの形状であってもよい。It should be noted that one end of the thread tube body 6 forms the arcuate arc-shaped arc portion 11 that has been pressed as described above, but the other end may have a shape that is cut.

た。As described above, the yarn winding tube of the present invention comprises a thread tube body in which a surface sheet is laminated on the outer peripheral surface of the thread tube, and the thread tube is formed by winding cardboard in a spiral shape in multiple layers. And
The end portion of the thread tube body is an arc portion having an arc-shaped cross section by pressing, and the surface layer sheet is formed by extending and covering a part of the arc portion. Fine cracks and gaps that cause delamination are no longer generated.
更に、表層シートには、絞り皺や耳立ちが生じないか

毛羽立ち、糸切れ等のトラブルが激減するようになっ
た。Furthermore, since the surface layer sheet does not have draw wrinkles or selvages, single yarn cracks due to draw wrinkles or selvages of the surface layer sheet,
Problems such as fluffing and thread breakage have been dramatically reduced.
