Description
【０００１】[0001]
本考案は糸条を移送するロ−ラ（処理ロ−ラ等を含む）、更に詳しくは対磨耗 性の向上を図るために表面処理を施した糸条移送用ロ−ラに関する。 The present invention relates to a roller for transferring a yarn (including a treatment roller, etc.), and more particularly to a yarn transfer roller for which a surface treatment has been performed in order to improve wear resistance.
【０００２】[0002]
糸条の移送用ロ−ラ、例えば合成繊維糸条を処理する紡糸機、延伸機あるいは 仮撚加工機等の繊維機械においては連続的に糸条を処理するため、一般に糸条を 回転ロ−ラに巻き掛けて移送するが、このような移送ロ−ラとしては対磨耗性を 考慮して炭素鋼を母材とするロ−ラ表面に硬質クロムメッキを施したものが用い られる。 In a yarn transfer roller, for example, a spinning machine, a drawing machine, or a false twisting machine that processes synthetic fiber yarns, the yarns are continuously processed because the yarns are continuously processed. It is wound around a roller and transferred, and as such a transfer roller, a roller made of carbon steel and having a hard chromium plated surface is used in consideration of abrasion resistance.
【０００３】[0003]
しかしながら、硬質クロムメッキは硬度も高く、耐蝕、耐磨耗性に優れたもの であるが、ポリエステル、ポリアミド繊維等の処理の場合は繊維によるロ−ラ表 面の磨耗は避けられない。 However, although hard chrome plating has high hardness and excellent corrosion resistance and abrasion resistance, abrasion of the roller surface due to fibers is unavoidable in the case of treating polyester or polyamide fibers.
【０００４】 また、糸条を糸掛けする際に糸掛具による打痕による傷などの損傷も受けやす い。更にロ−ラの磨耗、打痕が敏感に糸条の処理性に影響し、糸条の巻き付き、 断糸、毛羽等を誘発するので、特に超極細糸の場合はロ−ラ表面の管理は生産上 大きな問題である。Further, when the yarn is threaded, it is easily damaged by a dent by a thread hooking tool. In addition, the abrasion and dents of the roller sensitively affect the processability of the yarn and induce winding of the yarn, yarn breakage, fluff, etc. This is a big problem in production.
【０００５】 このようなロ−ラ表面の耐磨耗性向上の手段としてロ−ラ表面にＣＶＤ（化学 蒸着）等の蒸着法を用いるには母材の処理温度が１０００℃近くの高温となるた め歪みが発生して製作精度が悪くなり、これに伴い糸の品質にも悪影響を与える 問題があった。To use such a vapor deposition method as CVD (chemical vapor deposition) on the roller surface as a means for improving the abrasion resistance of the roller surface, the processing temperature of the base material becomes a high temperature of about 1000 ° C. As a result, distortion occurs and manufacturing accuracy deteriorates, which also adversely affects the yarn quality.
【０００６】[0006]
【課題を解決するための手段】 本考案は前記のような問題を解決するためになされたものであり、糸条の移送 あるいは処理するロ−ラにおいて、少なくとも糸条走行面が母材表面に形成した 硬質クロムメッキ層と該硬質クロムメッキ層を被覆した炭化ケイ素（ＳｉＣ）層 からなる表面を有していることを特徴とする糸条移送用ロ−ラである。Means for Solving the Problems The present invention has been made to solve the above problems, and in a roller for transferring or treating a yarn, at least the yarn running surface is on the surface of the base material. A yarn transfer roller having a surface comprising a formed hard chrome plating layer and a silicon carbide (SiC) layer covering the hard chrome plating layer.

かかる本願考案によると、硬質クロムメッキ層の上に、さらに耐磨耗性のある Ｓi Ｃ層を形成することによりＳi Ｃ層の耐磨耗性がさらに向上し、またＳi Ｃ 層はＰＶＤ法（物理蒸着法）により形成されるため母材の処理温度が低い（４０ ０〜５００℃）ので歪みもほとんどなく、このため生産される糸条の品質も向上 する。 According to the present invention, the abrasion resistance of the SiC layer is further improved by forming the abrasion resistant SiC layer on the hard chromium plating layer, and the SiC layer is formed by the PVD method ( Since it is formed by the physical vapor deposition method, the processing temperature of the base material is low (400 to 500 ° C.), so there is almost no distortion, and therefore the quality of the yarn produced is improved.

以下、本考案を図面に基いて説明する。図１は本考案の実施例を示す概略断面 図である。 Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 is a schematic sectional view showing an embodiment of the present invention.
【０００９】 図１（ａ）において、１は本校案に係る移送用ロ−ラの本体で、回転軸に嵌合 するボス部２と糸条を案内するシェル部３から構成される。シェル部３の外表面 が糸条走行面（案内面）すなわち糸条巻掛け部であり、この外表面はＡ部拡大図 である図１（ｂ）に示すように炭素鋼からなる母材（基材）４と該母材４に形成 された硬質クロムメッキ層５および該硬質クロムメッキ層５を被覆するＳｉＣ層 ６からなる。In FIG. 1A, reference numeral 1 is a main body of a transfer roller according to the present invention, which is composed of a boss portion 2 fitted to a rotating shaft and a shell portion 3 guiding a yarn. The outer surface of the shell portion 3 is the yarn running surface (guide surface), that is, the yarn winding portion, and this outer surface is a base material made of carbon steel (see Fig. 1 (b) which is an enlarged view of part A). The substrate 4), the hard chrome plating layer 5 formed on the base material 4, and the SiC layer 6 covering the hard chrome plating layer 5.
【００１０】 ＳｉＣ層６は母材４に硬質クロムメッキ層５を形成した後、ＰＶＤ法の一種で あるイオンプレ−ティングによって形成したものである。The SiC layer 6 is formed by ion-plating, which is a kind of PVD method, after the hard chromium plating layer 5 is formed on the base material 4.
【００１１】 以上は糸条を移送するロ−ラを例として説明したが、これに限定されるもので はなく、例えば加熱ロ−ラやガイドロ−ラなど糸条の送り作用あるいは案内をす る作用を有するものであれば同様に適用できる。Although the above description has been made by taking a roller for transferring the yarn as an example, the present invention is not limited to this, and for example, a heating roller, a guide roller, or the like may be used for feeding or guiding the yarn. The same applies as long as it has an action.
【００１２】 以上の例はロ−ラの外表面全体を糸条走行面としたものについて説明したが、 走行路が一定の場合はそれに応じて定まった糸条走行路の部分のみに適用しても よく、また糸条走行路の一部のみに利用してもよい。In the above example, the entire outer surface of the roller was used as the yarn running surface. However, when the running route is constant, it is applied only to the part of the yarn running route determined accordingly. Alternatively, it may be used for only a part of the yarn running path.
【００１３】[0013]
このようにロ−ラ表面に下地として硬質クロムメッキ層を形成して、その上に 耐磨耗性のあるＳｉＣ層を低温で蒸着することによりロ−ラの製作精度を低下さ せることなく耐磨耗性の向上が可能になり、長期間に亙って品質の優れた糸条製 品を安定して得ることができるというきわめて顕著な効果を奏する。 In this way, a hard chrome plating layer is formed as a base on the roller surface, and a wear-resistant SiC layer is vapor-deposited at a low temperature on the roller surface, so that the roller manufacturing accuracy is not deteriorated. The abrasion property can be improved, and a remarkable effect that a yarn product of excellent quality can be stably obtained over a long period of time is achieved.
