本考案は糸条巻取り用紙管の改良に関するもの
である。[Detailed Description of the Invention] The present invention relates to an improvement of a yarn-wound paper tube.
一般に高速紡糸によつて糸条を直接紙管に巻き
付ける場合、糸条が紡糸工程より直接連続的に供
給されるので、満捲紙管より空紙管への自動切換
時には、一時的に巻始めの糸条が弛緩して糸端が
空紙管より脱落し、迅速確実に糸条を捕捉しない
場合があつて、糸取り不良を発生する。このため
糸掛けの成功率を略々完全にすることが要求され
る。 Generally, when yarn is directly wound around a paper tube by high-speed spinning, the yarn is directly and continuously supplied from the spinning process, so when automatically switching from a full paper tube to an empty paper tube, the winding starts temporarily. When the yarn becomes loose, the yarn end falls off from the empty paper tube, and the yarn may not be captured quickly and reliably, resulting in poor yarn take-up. For this reason, it is required that the success rate of threading be almost perfect.
この切換時に糸条の捕捉に失敗すると、糸条が
前工程より高速で供給されるために、空紙管への
糸掛けが行われるまでの間、多量の損糸が発生し
て頗る不経済である。 If the yarn fails to be captured during this switching, the yarn is fed at a higher speed than the previous process, resulting in a large amount of lost yarn until it is threaded onto the empty paper tube, which is extremely uneconomical. It is.
このため従来から、糸条巻取り用紙管において
は、糸掛け捕捉率を向上するために、第１図に示
すように、紙管主体１の端部近傍に円周方向の開
口溝２を刻設すると共に、該開口溝２の延長上に
密接溝３を刻設した紙管が使用されている。 For this reason, conventionally, in yarn-wound paper tubes, opening grooves 2 in the circumferential direction have been carved near the end of the paper tube main body 1, as shown in FIG. 1, in order to improve the thread catching rate. In addition, a paper tube is used in which a close contact groove 3 is carved on the extension of the opening groove 2.
即ち、開口溝２は第２図に示すように、溝の肩
部を大きな曲面に形成して糸条をガイドし易くす
ると共に、密接溝３は第３図に示すように、溝の
肩部の曲面を小さくして、密接面積を大きくし、
この密接溝３に糸条を導入して捕捉固定し、満捲
紙管よりの糸条を切断してその糸端を空紙管に巻
き付けるようにしていた。 That is, as shown in FIG. 2, the open groove 2 has a shoulder portion of the groove formed into a large curved surface to facilitate guiding the yarn, and the close groove 3 has a shoulder portion of the groove as shown in FIG. By reducing the curved surface and increasing the close contact area,
A thread is introduced into the tight groove 3 and caught and fixed, and the thread from the full paper tube is cut and the end of the thread is wound around the empty paper tube.
併し、この糸条導入溝である開口溝２及び糸条
捕捉溝である密接溝３の溝加工には、刃先の切味
の良い直線加工刃が用いられていたので、密接溝
３には若干の隙間を生じ、細デニールの糸条の捕
捉に際しては、運動方向性によつて完全に糸条を
捕捉できない欠点があつた。 However, since a straight cutting blade with a sharp cutting edge was used to process the opening groove 2, which is the yarn introduction groove, and the close groove 3, which is the yarn catching groove, a straight cutting blade with a sharp cutting edge was used. A slight gap was created, and when capturing a fine denier yarn, there was a drawback that the yarn could not be completely captured due to the directionality of movement.
本考案はこのような従来の欠点をなくするため
に、密接溝の部分を２区分に分け、糸条の運動性
の方向に関係なく、細デニールの糸をも完全に捕
捉して捕捉機能を向上するようにした糸条巻取り
用紙管を提供するものである。 In order to eliminate these conventional drawbacks, the present invention divides the close groove part into two sections, and has a trapping function that completely traps even fine denier yarns, regardless of the direction of yarn movement. The present invention provides a yarn-wound paper tube which is improved in quality.
本考案の実施例を図面によつて説明すれば、第

近傍に開口溝２を刻設すると共に、該開口溝２の
延長上に密接溝３を刻設し、さらに、該密接溝３

てある。 An embodiment of the present invention will be described with reference to the drawings. In Fig. 4, 1 is a paper tube main body, and an opening groove 2 is carved in the vicinity of the outer peripheral surface of the end thereof, and an extension of the opening groove 2 is formed. A close contact groove 3 is carved, and further, the close contact groove 3 is
A part of the opposing close contact surface is a roughened close contact groove 4.
上記の開口溝２及び密接溝３，４を紙管主体１

５図に示すように粗く乱立して糸条を捕捉し易く
なつている。 The above opening groove 2 and close grooves 3 and 4 are connected to the paper tube main body 1.
6 and 7, the opening groove 2 is machined with the cutting edge a, and the close grooves 3 and 4 are formed with the cutting edge b 1 and b, respectively. Machining is done in part b 2 , that is, cutting blade a and cutting blade b 1 have straight and smooth cutting edges, but the cutting edge of cutting blade b 2 has minute serrated irregularities. Therefore, when the groove is formed in this part, the paper fibers on the groove surface are coarsely scattered as shown in FIG. 5, making it easier to catch the yarn.

選択することができる。 In addition, when capturing and gripping a yarn, the behavior of the yarn may move freely in the circumferential direction, radial direction, or other directions due to various causes, so in any case, it is necessary to ensure that the yarn is captured and gripped reliably. The shape and length of each of the open groove 2 and close contact grooves 3 and 4 of the present invention, and the front and rear positions of the grooves can be appropriately selected depending on the conditions of use.
本考案の紙管を使用するときは、例えば合繊糸
75デニールの糸条の把持力が従来約100ｇであつ
たものが、約２倍の200ｇとなつた。 When using the paper tube of the present invention, for example, synthetic yarn
The gripping force for 75 denier thread was approximately 100g, but it has been doubled to 200g.
なお、本考案の紙管を製造する場合、刃物の刃
先部に若干の修正加工を施すのみで、従来の装置
に何等変更を加える必要がないものである。 In addition, when manufacturing the paper tube of the present invention, there is no need to make any changes to the conventional equipment except for making some modifications to the cutting edge of the cutter.

ず、経済的である等の特長を有する。 As described above, the present invention has at least one set of opening grooves 2 of an appropriate length on the outer peripheral surface near the end of the paper tube main body 1, and a close contact groove 3 in the circumferential direction on an extension of the opening grooves 2. Since this relates to a thread-wound paper tube, a part of the close-contact groove 3 has a close-contact groove 4 formed on the rough surface by cutting with a serrated blade, When switching the yarn from the tube to the empty paper tube, even if the yarn introduced to the opposite surface of the close groove 4 is a fine denier yarn, the close groove 4 whose opposite surface is formed with a rough surface The yarn end can be strongly pinched and captured reliably, improving the yarn hooking and catching rate, reducing yarn take-up defects, and contributing to improved productivity. The cutter for this purpose requires only slight modification of the cutting edge, does not require any changes to the equipment, and has the advantage of being economical.
