- the inclination direction 8 of the biting corner 5 is the entry side to the fiber tuft. That is, the direction opposite to the inclination direction 8 is the exit side from the fiber tuft. Therefore, when viewed from the spinning needle, it can be said that the thin portion 9 is formed on the edge 5b on the exit side to the fiber tuft.

Abstract
In order to perform high-speed operation of a comber, impurities or the like must be promptly removed from a top comb or a cylindrical comb. Conventionally, a spinning pin was grinded or a DLC film was formed on a surface of the spinning pin, thereby enhancing specularity or hardness. However, inventiveness for more easily removing the impurities or the like is desired.
Provided is a spinning pin, wherein impurities or the like are easily eliminated by providing a thin portion on a tip section of the spinning pin. The thin portion is provided on an edge opposite to an inclined side of an ingress corner portion, thereby being capable of enhancing elimination of the impurities or the like while having a sufficient coming effect.
Description
本発明は、コーマに用いる紡績針と、その紡績針を用いたトップコームおよびシリンドリカルコームに関するものであり、より詳しくは、紡績針の厚みを部分的に薄くした薄肉部を有する紡績針とそれを用いたトップコームおよびシリンドリカルコームとそれらを用いたコームに関するものである。
The present invention relates to a spinning needle used for a comb, a top comb and a cylindrical comb using the spinning needle, and more specifically, a spinning needle having a thin-walled portion in which the thickness of the spinning needle is partially reduced and the spinning needle. The present invention relates to the top comb and cylindrical comb used and the combs using them.
羊毛や綿などの原料から糸を製造する過程では、繊維を梳(くしけず)ることで、繊維の方向を揃えるカーディング工程が施される。カーディングされた繊維はスライバーと呼ばれる。さらにこのスライバー中の、短い糸が絡み合ってできた小球であるネップおよび、短繊維やカス等の夾雑物を除去するためにコーミングと呼ばれる工程が行われる。
In the process of manufacturing yarn from raw materials such as wool and cotton, a carding process is performed to align the fiber direction by wrinkling the fiber. The carded fiber is called a sliver. Further, a step called combing is performed in order to remove the nep, which is a small sphere formed by intertwining short yarns in the sliver, and foreign matters such as short fibers and debris.
紡績装置の中でコーミングを行うコーミング部(若しくはコーミングだけを行うコーミング機)には、処理されるスライバー(以後「ファイバータフト」と呼ぶ。)を少しずつつまみ出すニッパ部と、ニッパ部によってつまみ出されたファイバータフトの先頭に近い部分を下方からコーミングするシリンドリカルコームと、ファーバータフトの終端に近い部分を上方からコーミングするトップコームが備えられている。
A combing unit that performs combing in a spinning device (or a combing machine that performs only combing) includes a nipper unit that picks up a processed sliver (hereinafter referred to as a “fiber tuft”) little by little, and a nipper unit. In addition, a cylindrical comb that combs the portion near the top of the fiber tuft from below and a top comb that combs the portion near the end of the fiber tuft from above are provided.
これらのコームには、紡績針が備えられており、ファイバータフトを梳りながらネップや夾雑物を除去する。コーミング処理が行われたスライバーは、コーマスライバーと呼ばれ、このコーマスライバーの品質が紡績の品質の大部分を決めるともいわれている。
These combs are equipped with spinning needles, which remove the nep and other impurities while rolling the fiber tuft. The sliver subjected to the combing process is called a comb sliver, and it is said that the quality of the comb sliver determines most of the spinning quality.
トップコームは、一方向に傾斜した喰込角部を有する紡績針が方向をそろえて直線状に固定された、いわば、櫛のような形状である。一方、シリンドリカルコームは、回転するシリンダの表面に固定された円弧状の基台の表面に、一方向に傾斜した喰込角部を有する紡績針が方向をそろえて植設されている。
The top comb has a comb-like shape in which spinning needles having biting corners inclined in one direction are aligned and fixed in a straight line. On the other hand, in the cylindrical comb, spinning needles having biting corners inclined in one direction are planted in the same direction on the surface of an arc-shaped base fixed to the surface of a rotating cylinder.
これらのコームに配置された紡績針が、ファイバータフトに進入し、梳ることでコーミングは行われる。しかし、梳ることで、ネップや夾雑物(以後まとめて「夾雑物等」と呼ぶ。)がコームに絡まる。絡まった夾雑物等は、そのままにしておくとコーミングの際にコーマスライバーに戻してしまい再汚染のおそれが発生する。また、夾雑物等が付着したままコーミングを続けると、紡績針とファイバータフトとの間で大きな摩擦が生じ、紡績針自体の寿命を短くすることにも繋がる。そこで、コーミング部には、コームに絡みつく夾雑物等を除去するためのブラシ等の除去手段が設けられている。
Combing is performed when the spinning needles arranged in these combs enter the fiber tuft and beat. However, the nep and the foreign matters (hereinafter collectively referred to as “the foreign matters etc.”) are entangled with the comb when they hit. If the entangled impurities are left as they are, they are returned to the comb river during combing, and there is a risk of recontamination. In addition, if combing is continued with foreign matter or the like attached, a large friction is generated between the spinning needle and the fiber tuft, which leads to shortening of the life of the spinning needle itself. Therefore, the combing unit is provided with a removing means such as a brush for removing foreign matters and the like entangled with the comb.
しかし、紡績針は、傾斜した喰込角部を有し、また緻密に植設されているため、複雑に絡まった夾雑物等は容易には除去できない場合もある。コーマの運転は高速化を図られるため、夾雑物等の除去の時間も極めて短く一瞬で除去される必要がある。そのため、ブラシ等の除去手段だけに頼るのではなく、紡績針自体に工夫を加え夾雑物等の除去が行いやすくした発明も提案されている。
However, since the spinning needle has an inclined biting corner and is densely planted, there are cases where complicated entangled impurities cannot be easily removed. Since the operation of the comber can be speeded up, the time for removing impurities and the like is extremely short and needs to be removed in an instant. Therefore, an invention has been proposed in which the spinning needle itself is devised to make it easier to remove impurities and the like, rather than relying solely on a removing means such as a brush.
特許文献1には、紡績針の表面にダイヤモンドライクカーボン(以後「DLC」と呼ぶ。)膜を施したコーマ用の紡績針が開示されている。DLC膜は、イオン化蒸着法で形成されるダイヤモンドに類似した特性を有するカーボン薄膜の総称であり、硬度が大変高いという特性を有する。また、アモルファスであるため結晶粒界を持たず、紡績針の表面を均一膜で覆うと、表面粗さを小さくできる。このため、DLC膜を施した紡績針は、硬く、表面性も高いため、夾雑物等が容易に除去でき、さらに耐久性も向上する。
Patent Document 1 discloses a spinning needle for a comb in which a diamond-like carbon (hereinafter referred to as “DLC”) film is provided on the surface of the spinning needle. The DLC film is a general term for carbon thin films having characteristics similar to diamond formed by ionized vapor deposition, and has a characteristic that the hardness is very high. Further, since it is amorphous, it has no crystal grain boundaries, and the surface roughness can be reduced by covering the surface of the spinning needle with a uniform film. For this reason, the spinning needle provided with the DLC film is hard and has a high surface property, so that impurities and the like can be easily removed, and durability is further improved.
しかしながら、DLC膜の膜厚は極めて薄いため、0.5μm以下程度の粗さのカバーまでしか効果がなく、それ以上の紡績針表面の凸凹は、DLC膜を施したとしても、残ってしまう。ある程度大きな凸凹が紡績針に残っていると、夾雑物等は容易に除去できない場合がある。
However, since the thickness of the DLC film is extremely thin, it is effective only for a cover having a roughness of about 0.5 μm or less, and the unevenness on the surface of the spinning needle remains even if the DLC film is applied. If a certain degree of unevenness remains on the spinning needle, impurities and the like may not be easily removed.
紡績針の製造工程では、物理的および化学的な研磨工程を導入し、大きな凸凹は表面から極力除去できるようにしている。しかし、それでも、完全な除去ができない場合もある。また、すでに説明したようにコーマの高速運転化はますます要望されており、よりすばやい、すなわち、容易な夾雑物等の除去の要望がますます高くなってきている。
In the spinning needle manufacturing process, physical and chemical polishing processes are introduced so that large irregularities can be removed from the surface as much as possible. However, complete removal may still not be possible. Further, as described above, there is an increasing demand for high-speed operation of combs, and there is an increasing demand for quicker, that is, easy removal of contaminants.
本発明は、上記のような課題に鑑み想到されたものであり、紡績針の形状を改良することで、より夾雑物等の脱離性を容易にした紡績針およびその紡績針を用いたトップコームおよびシリンドリカルコームを提供しようとするものである。より具体的には、本発明の紡績針は、厚みが部分的に薄い薄肉部を有することを特徴とする。
The present invention has been conceived in view of the problems as described above, and a spinning needle that has improved the shape of the spinning needle to make it easier to remove impurities and the like, and a top using the spinning needle. Combs and cylindrical combs are to be provided. More specifically, the spinning needle of the present invention is characterized by having a thin portion with a partially thin thickness.
本発明の紡績針は、平板状の紡績針の一部を肉薄に形成しているため、そもそも絡みついた夾雑物等が脱離しやすい形状をしている。従って、仮に紡績針の表面に凸凹が残存していたとしても、夾雑物等の脱離性は大変容易になるという効果を奏する。そのため、紡績針自体の耐久性も向上するという効果を奏する。
The spinning needle of the present invention is formed so that a part of the flat spinning needle is thin, so that the entangled impurities are easily detached. Therefore, even if unevenness remains on the surface of the spinning needle, there is an effect that it is very easy to remove impurities and the like. Therefore, there is an effect that the durability of the spinning needle itself is improved.
また、紡績針の一部に薄肉部を有するため、夾雑物等の除去手段が、配列された紡績針の隙間に入り易く、そのため夾雑物等の除去が容易に行えるという効果を奏する。
In addition, since the spinning needle has a thin portion, the removal means for contaminants and the like is easy to enter the gaps between the arranged spinning needles, so that the contaminants and the like can be easily removed.
以下に本発明について図面を参照しながら説明する。以下の説明は本発明の一実施形態について例示を行うだけであり、本発明が以下の実施形態に限定されるものではない。本発明の主旨を逸脱しない限りにおいて、以下の実施形態は変更して実施されても、本発明の技術的範囲に含まれるのは言うまでもない。
Hereinafter, the present invention will be described with reference to the drawings. The following description merely illustrates one embodiment of the present invention, and the present invention is not limited to the following embodiment. It goes without saying that the following embodiments are included in the technical scope of the present invention even if they are modified and implemented without departing from the gist of the present invention.
図1には、本発明の紡績針1の概略図を示す。図1(a)は正面図、図1(b)は側面図である。本発明の紡績針1は、略方形の基板2と、基板の一方辺に突設された略鉤型形状部3からなる。略鉤型形状部3は、押出角部4と喰込角部5とからなり、押出角部4は基板2に対して傾斜辺4aを有し、喰込角部5は、押出角部4の傾斜辺4aと反対方向に傾斜して形成される。
FIG. 1 shows a schematic view of the spinning needle 1 of the present invention. 1A is a front view, and FIG. 1B is a side view. The spinning needle 1 of the present invention includes a substantially square substrate 2 and a substantially bowl-shaped portion 3 protruding from one side of the substrate. The substantially bowl-shaped portion 3 includes an extrusion corner portion 4 and a biting corner portion 5. The extrusion corner portion 4 has an inclined side 4 a with respect to the substrate 2, and the biting corner portion 5 is an extrusion corner portion 4. The inclined side 4a is inclined in the opposite direction.
言い換えると、押出角部4と喰込角部5の間で「く」の字形状に屈曲した形状を構成している。また、喰込角部5は、基板2から離れる方向に向かって、針幅6は細くなり、紡績針1の先端は尖鋭端7となる。基板2に対して尖鋭端7が向かう方向を傾斜方向8と呼ぶ。なお、押出角部4と喰込角部5の間に中間部(図示せず)を有していても良い。
In other words, a shape bent between the extrusion corner 4 and the biting corner 5 in a “<” shape is formed. Further, the biting corner 5 has a narrower needle width 6 toward the direction away from the substrate 2, and the tip of the spinning needle 1 becomes a sharp end 7. A direction in which the sharp end 7 is directed toward the substrate 2 is referred to as an inclined direction 8. In addition, you may have an intermediate part (not shown) between the extrusion corner | angular part 4 and the biting corner | angular part 5. FIG.
さらに本発明の紡績針1は、喰込角部5の傾斜方向8と反対の反り側のエッジ5bに薄肉部9を有する。図2には、図1の喰込角部5のA-A断面形状を示す。矢印8が、喰込角部5の傾斜方向を示す。傾斜方向8側のエッジを前側エッジ5fと呼ぶ。その反対の反り側エッジ5bでは、針厚5tが他の部分より、薄くなった部分(薄肉部9)が形成されている。なお、薄肉部9の厚みを符号9tで表す。
Furthermore, the spinning needle 1 of the present invention has a thin portion 9 on the edge 5b on the warp side opposite to the inclination direction 8 of the biting corner portion 5. FIG. 2 shows an AA cross-sectional shape of the biting corner 5 of FIG. An arrow 8 indicates the inclination direction of the biting corner 5. The edge on the inclination direction 8 side is referred to as a front edge 5f. On the opposite warp side edge 5b, a portion (thin wall portion 9) in which the needle thickness 5t is thinner than other portions is formed. In addition, the thickness of the thin part 9 is represented by the code | symbol 9t.
コーマにおいては、喰込角部5の傾斜方向8がファイバータフトへの入り側となる。すなわち、傾斜方向8と反対方向がファイバータフトからの出側となる。したがって、紡績針から見ると、ファイバータフトへの出側のエッジ5bに肉薄部9が形成されているとも言える。このように、絡まった夾雑物等は、ファイバータフトへの出側のエッジ5bに薄肉部9を形成することで、薄肉部がない場合と比較して脱離しやすくなる。
In the comb, the inclination direction 8 of the biting corner 5 is the entry side to the fiber tuft. That is, the direction opposite to the inclination direction 8 is the exit side from the fiber tuft. Therefore, when viewed from the spinning needle, it can be said that the thin portion 9 is formed on the edge 5b on the exit side to the fiber tuft. In this way, entangled impurities and the like are easily detached by forming the thin portion 9 at the edge 5b on the exit side to the fiber tuft as compared with the case where there is no thin portion.
薄肉部9の幅9wは、紡績針1の針幅6の9/10(9m)より狭く、また1/10(9n)より広く形成するのが望ましい。ここで、符号9mは薄肉部9の最大幅であり、符号9nは薄肉部9の最小幅である。薄肉部9の幅9wが広すぎると、喰込角部5の厚さ自体が薄くなり、紡績針1の強度の低下や、厚みが薄くなることで紡績針1自体が切削力を有するため、繊維を傷つけるという問題が生じるからである。また、薄肉部9の幅9wが狭すぎると、夾雑物等の脱離性がよくならないからである。
The width 9w of the thin-walled portion 9 is preferably narrower than 9/10 (9m) of the needle width 6 of the spinning needle 1 and wider than 1/10 (9n). Here, reference numeral 9 m is the maximum width of the thin portion 9, and reference numeral 9 n is the minimum width of the thin portion 9. If the width 9w of the thin-walled portion 9 is too wide, the thickness of the biting corner portion 5 itself becomes thin, the strength of the spinning needle 1 is reduced, and the spinning needle 1 itself has a cutting force due to the thinness. This is because the problem of damaging the fiber occurs. Further, if the width 9w of the thin portion 9 is too narrow, the detachability of impurities and the like is not improved.
また、薄肉部9の厚み9tと他の部分(以後「厚肉部」と呼ぶ。)の厚みの比率は30%から80%程度であるのが好ましい。薄肉部9の厚み9tを薄くしすぎると、強度が低下しすぎる。また薄肉部9の厚み9tが厚肉部と変わらない程度であると、夾雑物等の脱離性が良くならないからである。
The ratio of the thickness 9t of the thin portion 9 to the thickness of the other portion (hereinafter referred to as “thick portion”) is preferably about 30% to 80%. If the thickness 9t of the thin portion 9 is made too thin, the strength is too low. Further, if the thickness 9t of the thin portion 9 is not different from that of the thick portion, the detachability of impurities and the like cannot be improved.
図2(b)および(c)には、薄肉部9のバリエーションの一部を例示する。図2(b)を参照して、薄肉部9は、厚肉部と同一平面を有していなくても良い。すなわち、図示するように、紡績針1の両側から圧力10を加え、厚肉部の両面側から段差に続く薄肉部9を形成してもよい。
FIGS. 2B and 2C illustrate some of the variations of the thin-walled portion 9. With reference to FIG.2 (b), the thin part 9 does not need to have the same plane as the thick part. That is, as shown in the drawing, pressure 10 may be applied from both sides of the spinning needle 1 to form a thin portion 9 that follows the step from both sides of the thick portion.
また、薄肉部9の形成範囲は、少なくとも喰込角部5の一部に施されていればよい。喰込角部5がファイバータフトに進入し、夾雑物等との関わりが大きいからである。もちろん、押出角部4や中間部に薄肉部9を形成してもよい。
Moreover, the formation range of the thin part 9 should just be given to at least one part of the biting corner part 5. This is because the biting corner 5 enters the fiber tuft and has a large relationship with the foreign matter. Of course, you may form the thin part 9 in the extrusion corner | angular part 4 or an intermediate part.
また、図2(c)を参照して、薄肉部9は厚肉部との間で必ずしも段差を形成する必要はない。例えば図示するように、厚肉部の部分から一方のエッジ5bに向かってなだらかに厚みが薄くなっていってもよい(9s)。言い換えると、薄肉部9は厚みの傾斜で構成されていてもよい。また、この傾斜は一定の勾配を有する傾斜でなくてもよい。薄肉部9を設けるために段差を設けようとして、明確な段差が設けられなかった場合も本発明の効果を得ることができるからである。
Referring to FIG. 2C, the thin portion 9 does not necessarily need to form a step between the thick portion. For example, as shown in the drawing, the thickness may be gradually reduced from the thick portion toward the one edge 5b (9s). In other words, the thin portion 9 may be configured with a thickness gradient. Further, this inclination may not be an inclination having a constant gradient. This is because the effect of the present invention can be obtained even when a step is provided to provide the thin portion 9 and a clear step is not provided.
なお、上記には、薄肉部9が紡績針1の喰込角部5の一方のエッジ5bに形成される場合について説明したが、図3に示すように、喰込角部5において、基板側2から喰込角部5の尖鋭部7方向に厚み傾斜が形成されることで薄肉部(9c)が形成されていてもよい。なお、図3(a)は平面図、図3(b)は側面図を示す。また、図3(b)では、説明のために厚み方向を図1(b)より拡大して示した。このように、紡績針1の長さ方向に薄肉部9が形成されても、夾雑物等の脱離を容易にすることができるからである。
In the above description, the thin portion 9 is formed on one edge 5b of the biting corner portion 5 of the spinning needle 1. However, as shown in FIG. The thin-walled portion (9c) may be formed by forming a thickness gradient from 2 to the sharp portion 7 direction of the biting corner portion 5. 3A is a plan view and FIG. 3B is a side view. In FIG. 3 (b), the thickness direction is shown enlarged from FIG. 1 (b) for explanation. Thus, even if the thin portion 9 is formed in the length direction of the spinning needle 1, it is possible to facilitate the detachment of impurities and the like.
次に図4を参照して、本発明の紡績針の製造方法を簡単に説明する。原材料となるのは板状の鋼材である。これを適宜幅の短冊20に切断する(図4(a))。次に短冊20の一方の辺に対して、打ち抜き加工を行う(図4(b))。打ち抜きで形成した部分が略鉤型形状部3を構成し、残りの部分が基板2を構成する部分である。次に紡績針1の所定位置に打圧加工によって薄肉部9を形成する(図4(c))。最後に全体に焼き入れ等の硬化工程を施して、紡績針1が連続した鋸歯状ワイヤ25が完成する(図4(d))。
Next, with reference to FIG. 4, the spinning needle manufacturing method of the present invention will be briefly described. The raw material is a plate-shaped steel material. This is cut into strips 20 having an appropriate width (FIG. 4A). Next, punching is performed on one side of the strip 20 (FIG. 4B). The part formed by punching constitutes the substantially bowl-shaped part 3, and the remaining part constitutes the substrate 2. Next, a thin portion 9 is formed at a predetermined position of the spinning needle 1 by punching (FIG. 4C). Finally, the whole is subjected to a hardening process such as quenching to complete the sawtooth wire 25 in which the spinning needles 1 are continuous (FIG. 4D).
なお、鋸歯状ワイヤ25は、紡績針1が連続して形成されたものであるが、鋸歯状ワイヤ25というまとまりで扱われる場合もある。そこで、基板2を構成する部分を基板帯22、略鉤型形状部3が連続する部分を針先帯23と呼ぶ。なお、上記の加工工程に関しては、機械的、化学的な研磨工程を特に示していないが、これらの研磨工程は適宜挿入される。
The sawtooth wire 25 is formed by continuously forming the spinning needle 1, but may be handled as a group of sawtooth wires 25. Therefore, a portion constituting the substrate 2 is referred to as a substrate band 22, and a portion where the substantially bowl-shaped portion 3 continues is referred to as a needle tip band 23. Note that although the mechanical and chemical polishing steps are not specifically shown for the above processing steps, these polishing steps are inserted as appropriate.
鋸歯状ワイヤ25の表面には、DLC膜をコーティングしてもよい。本発明の特徴である薄肉部9とDLC膜の組み合わせによって、より、効果的に夾雑物等を脱離させることができるからである。
The surface of the sawtooth wire 25 may be coated with a DLC film. This is because impurities and the like can be more effectively desorbed by the combination of the thin-walled portion 9 and the DLC film, which is a feature of the present invention.
次に本発明の紡績針1を用いたトップコームについて説明する。図5にトップコーム30の構成を示す。図5(a)は、全体を示す斜視図であり、図5(b)は一部の拡大図である。トップコーム30は、上記で示した鋸歯状ワイヤ25から紡績針1を切り出し、尖鋭端7を揃えて紡績針1の厚み方向に並設固定したものである。トップコーム30は、紡績針1を挟持する一対の挟持板31a、31bと紡績針1からなる。
Next, a top comb using the spinning needle 1 of the present invention will be described. FIG. 5 shows the configuration of the top comb 30. Fig.5 (a) is a perspective view which shows the whole, FIG.5 (b) is a one part enlarged view. The top comb 30 is obtained by cutting the spinning needle 1 from the sawtooth wire 25 shown above and aligning and fixing the sharp ends 7 in the thickness direction of the spinning needle 1. The top comb 30 includes a pair of clamping plates 31 a and 31 b that clamp the spinning needle 1 and the spinning needle 1.
挟持板31a、31bは、紡績針1を挟持する保持手段と、コーマに設けられる把持手段で固定されるための持ち手としての役目を負う。形状は特に限定されるものではなく、単純な方形であってもよい。材質も挟持のための強度を確保できれば、金属であっても樹脂であっても、また複合材料であってもよい。なお、紡績針1を挟持するため、一対として説明しているが、挟持板31a、31bの形状は同じである必要はなく、一方が小さくまた、別形状で形成されていてもよい。
The holding plates 31a and 31b serve as a handle for holding the spinning needle 1 with a holding means and a holding means provided on the comb. The shape is not particularly limited and may be a simple square. The material may be a metal, a resin, or a composite material as long as the strength for clamping can be secured. In addition, in order to clamp the spinning needle 1, although demonstrated as a pair, the shape of the clamping plates 31a and 31b does not need to be the same, and one side may be small and may be formed in another shape.
トップコーム30には、上記に説明した鋸歯状ワイヤ25から紡績針1を切り出して使用する。厚み方向に積層するからである。なお、鋸歯状ワイヤ25の基板帯22の部分には、鋸歯状ワイヤ25から紡績針1を切り出した後に、ノッチとなる貫通孔21を形成しておいてもよい(図4参照)。針先を揃え、固定する際に基準とできるからである。また、紡績針1同士の間には適宜スペーサ32を入れて、並設の際の紡績針1間のピッチを調節してもよい。
For the top comb 30, the spinning needle 1 is cut out from the sawtooth wire 25 described above and used. This is because they are laminated in the thickness direction. In addition, in the portion of the substrate band 22 of the sawtooth wire 25, a through hole 21 serving as a notch may be formed after the spinning needle 1 is cut out from the sawtooth wire 25 (see FIG. 4). This is because it can be used as a reference when aligning and fixing the needle tips. Further, a spacer 32 may be appropriately inserted between the spinning needles 1 to adjust the pitch between the spinning needles 1 when they are arranged side by side.
紡績針1は、コーマのコーミング部に応じた幅に、所定のピッチで並設される。つまり、トップコーム30は各紡績針1の尖鋭端7が揃って配設されている。したがって、トップコーム30は、一方の面(例えば図5では挟持板31bの方向)に喰込角部5が傾斜した櫛形状に形成されることになる。そして本発明のトップコーム30はさらに、傾斜した反対のエッジ5bに薄肉部9が形成されている。
The spinning needles 1 are arranged in parallel at a predetermined pitch in a width corresponding to the combing portion of the comb. That is, the top comb 30 is provided with the sharp ends 7 of the spinning needles 1 aligned. Therefore, the top comb 30 is formed in a comb shape in which the biting corner portion 5 is inclined on one surface (for example, the direction of the sandwiching plate 31b in FIG. 5). In the top comb 30 of the present invention, the thin portion 9 is further formed on the inclined opposite edge 5b.
コーマにおいては、このトップコーム30がニップ部によってつまみ出されたファイバータフトを上方から進入しコーミングを行う。そして、本発明のトップコーム30に絡みついた夾雑物等はブラシ等の除去手段によって容易に除去することができる。この動作に関しては後述する。
In the comber, the top comb 30 enters the fiber tuft picked up by the nip portion from above and performs combing. And the foreign matter entangled in the top comb 30 of the present invention can be easily removed by removing means such as a brush. This operation will be described later.
また、紡績針1の基板2から尖鋭端7に向かって厚み勾配が形成された場合(9c)においても、同様に尖鋭端7を揃えて並設固定することでトップコーム30を形成することができる。
Even when a thickness gradient is formed from the substrate 2 of the spinning needle 1 toward the sharp tip 7 (9c), the top comb 30 can be formed by aligning and fixing the sharp tips 7 in parallel. it can.
次に本発明の紡績針1を用いたシリンドリカルコーム40について説明する。図6はシリンドリカルコーム40の構成を示す。図6(a)は全体を示す斜視図であり、図6(b)は、一部断面・一部側面図である。シリンドリカルコーム40は、円弧状の基板帯22に針先帯23を形成した鋸歯状ワイヤ25を、基台41のシリンドリカル面に、その軸方向に配列して固定したものである。基台41の軸方向の両端面には、側板42が固定されている。
Next, the cylindrical comb 40 using the spinning needle 1 of the present invention will be described. FIG. 6 shows the configuration of the cylindrical comb 40. FIG. 6A is a perspective view showing the whole, and FIG. 6B is a partial cross-sectional view and a partial side view. The cylindrical comb 40 is configured by fixing a sawtooth wire 25 in which a needle tip band 23 is formed on an arc-shaped substrate band 22 on the cylindrical surface of a base 41 in the axial direction. Side plates 42 are fixed to both end surfaces of the base 41 in the axial direction.
基台41は、厚みのある側面を有する円筒を所定角度で軸方向に切り出した断面扇形の柱状をした本体部41aと、コーマ側の駆動回転軸に固定されるための脚を兼ねたフランジ41bで構成されている。基台41の材質はアルミニウム系の金属が多用される。加工が容易であるのと、強度の観点から好適であるからである。しかし、FRP(Fiber Reinforced Plastics)などの繊維強化プラスチックなどで形成されていてもよい。なお、説明の便宜上、基台41の周方向においてファイバータフトに向かう方向を前方端41f、その反対側を後方端41rと呼ぶ。前方端41fと後方端41rで特に形状的な差異はなくてもよい。紡績針1が配置された際には、喰込角部5の傾斜方向8が前方端41fであり、その反対が後方端41rである。
The base 41 is a main body 41a having a sectoral columnar shape in which a cylinder having a thick side surface is cut out in the axial direction at a predetermined angle, and a flange 41b that also serves as a leg to be fixed to the drive rotation shaft on the comber side. It consists of Aluminum base metal is often used as the material of the base 41. This is because processing is easy and it is preferable from the viewpoint of strength. However, it may be formed of fiber reinforced plastic such as FRP (Fiber Reinforced Plastics). For convenience of explanation, the direction toward the fiber tuft in the circumferential direction of the base 41 is referred to as a front end 41f, and the opposite side is referred to as a rear end 41r. There is no particular difference in shape between the front end 41f and the rear end 41r. When the spinning needle 1 is disposed, the inclination direction 8 of the biting corner 5 is the front end 41f, and the opposite is the rear end 41r.
シリンドリカルコーム40に使われる鋸歯状ワイヤ25は、扇形をした基板帯22の外側円弧部分に針先帯23が形成されたものであり、紡績針1が連続形成されたものが使用される。扇形の基板帯22の内側円弧の曲率は、基台41のシリンドリカル面の曲率と同じに形成する。鋸歯状ワイヤ25を基台41表面に、周方向に沿って配置するためである。ここで使用される鋸歯状ワイヤ25は、基板帯22が扇形をしている点を除けば、上記(紡績針の作製)で説明した鋸歯状ワイヤ25と同じである。
The sawtooth wire 25 used in the cylindrical comb 40 is one in which the needle tip band 23 is formed on the outer circular arc portion of the fan-shaped substrate band 22 and the spinning needle 1 is continuously formed. The curvature of the inner arc of the fan-shaped substrate band 22 is formed to be the same as the curvature of the cylindrical surface of the base 41. This is because the serrated wire 25 is arranged on the surface of the base 41 along the circumferential direction. The sawtooth wire 25 used here is the same as the sawtooth wire 25 described above (preparation of spinning needle) except that the substrate band 22 has a fan shape.
鋸歯状ワイヤ25は、基台41の周方向に区切られたセグメント(43a乃至43d)毎に異なったピッチのものが配置されてもよい。鋸歯状ワイヤ25において、同一基板帯22上での鉤型形状部3間のピッチ(以後これを「進行方向ピッチ」と呼ぶ。)が狭いと、コーミングの効果は高いが、ファイバータフトへの進入抵抗は高くなる。そこで、シリンドリカルコーム40においては、最初にファイバータフトに進入する前方端41fの紡績針1の進行方向ピッチを広くし、後方端41rにいくほど進行方向ピッチを狭くするのが、好ましいからである。なお、鉤型形状部3のピッチは、紡績針間のピッチといっても良い。
The sawtooth wire 25 may have a different pitch for each segment (43a to 43d) partitioned in the circumferential direction of the base 41. In the serrated wire 25, if the pitch between the saddle-shaped portions 3 on the same substrate band 22 (hereinafter referred to as “traveling direction pitch”) is narrow, the effect of combing is high, but the approach to the fiber tuft. Resistance increases. Therefore, in the cylindrical comb 40, it is preferable to first widen the traveling direction pitch of the spinning needle 1 at the front end 41f entering the fiber tuft, and narrow the traveling direction pitch toward the rear end 41r. Note that the pitch of the saddle-shaped portions 3 may be referred to as a pitch between spinning needles.
また、鋸歯状ワイヤ25は、基台41の軸方向に配列させる際に、紡績針がファイバータフトに進入する方向に対して、平行な方向(シリンドリカル面の周方向)からわずかに迎え角を形成して配置されてもよい。図7には、シリンドリカルコーム40の端部の平面図を示す。シリンドリカル面は4つの区画(43a乃至43d)に区切られ、それぞれ進行方向ピッチの異なる鋸歯状ワイヤ25が配列される。そして、それぞれの鋸歯状ワイヤは、シリンドリカルコーム40の前方端41fから後方端41rに向かう方向に対して迎え角44(44a乃至44d)を有する。
Further, when the sawtooth wires 25 are arranged in the axial direction of the base 41, a slight angle of attack is formed from a direction parallel to the direction in which the spinning needle enters the fiber tuft (the circumferential direction of the cylindrical surface). May be arranged. In FIG. 7, the top view of the edge part of the cylindrical comb 40 is shown. The cylindrical surface is divided into four sections (43a to 43d), and sawtooth wires 25 having different traveling direction pitches are arranged. Each serrated wire has an angle of attack 44 (44a to 44d) with respect to the direction from the front end 41f of the cylindrical comb 40 toward the rear end 41r.
そして、この迎え角44は、所定の区間毎で反転されるのが好ましい。より具体的には、迎え角44aと迎え角44bは反対方向へ向かう角度に設定される。つまり、鋸歯状ワイヤ25は周方向(前方端41fから後方端41rの方向)に、所定の区画毎にジグザグに配置される。このように、周方向に対してジグザグに配置することで、繊維に対して「しごき」の効果が付加され、よりコーミング効果を高めることができるからである。
The angle of attack 44 is preferably reversed every predetermined interval. More specifically, the angle of attack 44a and the angle of attack 44b are set to angles in opposite directions. That is, the sawtooth wire 25 is arranged in a zigzag manner for each predetermined section in the circumferential direction (direction from the front end 41f to the rear end 41r). In this way, by arranging in a zigzag manner in the circumferential direction, an effect of “squeezing” is added to the fiber, and the combing effect can be further enhanced.
なお、ジグザグに配置する区間は適宜選択されることができ、迎え角44を設けない区間があってもよい。この迎え角44を設ける区画と、紡績針1の進行方向ピッチを変える区間43を同じにしてもよいし、異なる区画で設けても良い。ここで異なる区画があるというのは、ある進行方向ピッチの区画43において、迎え角44が異なる紡績針1があってもよいことを意味する。また、これらの「区画」は「領域」と言い換える事もできる。
In addition, the section to be arranged in a zigzag can be selected as appropriate, and there may be a section in which the angle of attack 44 is not provided. The section where the angle of attack 44 is provided may be the same as the section 43 where the spinning direction pitch of the spinning needle 1 is changed, or may be provided in different sections. Here, the fact that there are different sections means that there may be spinning needles 1 having different angles of attack 44 in sections 43 of a certain traveling direction pitch. In addition, these “sections” can be rephrased as “areas”.
基台41の軸方向の両端には側板42が配置される。側板42は、基台41の本体部41aの両端を覆い、鋸歯状ワイヤ25の尖鋭端7より低い位置で固定される(図6(b)参照)。側面からの外力から鋸歯状ワイヤ25を保護し、なおかつ喰込角部5がファイバータフトに進入するのを妨げないためである。
Side plates 42 are disposed at both ends of the base 41 in the axial direction. The side plate 42 covers both ends of the main body 41a of the base 41, and is fixed at a position lower than the sharp end 7 of the sawtooth wire 25 (see FIG. 6B). This is because the saw-toothed wire 25 is protected from external force from the side surface and does not prevent the biting corner 5 from entering the fiber tuft.
図8には側板42を示す。側板42のシリンドリカル面に向かう面(以後「内側面41i」と呼ぶ。)には、鋸歯状ワイヤ25の迎え角44に応じたゲージ面42gが形成されている。ゲージ面42gは一方の側板42の内面では、迎え角44に応じて凸状の傾斜面43aを形成し、他方の側板42の内面では、逆に凹状の傾斜面43bによって形成される。
FIG. 8 shows the side plate 42. A gage surface 42g corresponding to the angle of attack 44 of the sawtooth wire 25 is formed on the surface of the side plate 42 facing the cylindrical surface (hereinafter referred to as “inner side surface 41i”). The gauge surface 42g is formed on the inner surface of one side plate 42 with a convex inclined surface 43a according to the angle of attack 44, and on the inner surface of the other side plate 42, it is formed with a concave inclined surface 43b.
鋸歯状ワイヤ25を配置する際には、側板42を下方に配置し、このゲージ面42gを基準面として、順次鋸歯状ワイヤ25を積み上げていくことによって、容易に迎え角44を持った配置が可能となる。また、凸凹状の傾斜面43がそれぞれ両端の側板42に形成されているので、両端から鋸歯状ワイヤ25を狭持することで、シリンドリカルコーム40を形成後、迎え角44がずれることもない。
When the sawtooth wire 25 is disposed, the side plate 42 is disposed below, and the sawtooth wire 25 is sequentially stacked with the gauge surface 42g as a reference surface, whereby an arrangement having an angle of attack 44 can be easily performed. It becomes possible. Moreover, since the uneven inclined surfaces 43 are formed on the side plates 42 at both ends, the angle of attack 44 does not shift after the cylindrical comb 40 is formed by sandwiching the sawtooth wire 25 from both ends.
次に本発明のトップコームおよびシリンドリカルコームを用いたコーミング部について説明する。以後の説明は、紡績の工程を連続で行う装置のコーミングを行う部分(コーミング部)であってもよい、コーミングだけを行うコーミング機であってもよい。いずれの場合も単に「コーマ」と呼ぶ。
Next, the combing unit using the top comb and the cylindrical comb of the present invention will be described. The following description may be a combing portion (combing unit) of a device that continuously performs the spinning process or a combing machine that performs only combing. In either case, it is simply called “comb”.
図9は、コーマのコーミングを行う部分の構成を示す図である。ファイバータフト60は、ニップ部51によって、所定長さだけつまみだされる。ファイバータフト60には、夾雑物等61が、まだ残留している。下方では駆動軸50上に固定されたシリンドリカルコーム40が矢印の方向に所定速度で回転している。シリンドリカルコーム40の回転軌跡を一点鎖線で表した。
FIG. 9 is a diagram showing a configuration of a portion that performs combing of combs. The fiber tuft 60 is picked up by a predetermined length by the nip portion 51. In the fiber tuft 60, impurities 61 and the like still remain. Below, the cylindrical comb 40 fixed on the drive shaft 50 rotates at a predetermined speed in the direction of the arrow. The rotation trajectory of the cylindrical comb 40 is represented by a one-dot chain line.
駆動軸50の下方には、シリンドリカルコーム40から夾雑物等61を除去するための、回転ブラシ53が配置されている。また、ニップ部51の上方には、トップコーム30が図示していない駆動腕に固定されている。トップコーム30にも、夾雑物等61を除去するためのブラシ52が配置されている。なお、以下の説明では、夾雑物等の除去手段としてブラシ若しくは回転ブラシを記載しているが、特にブラシに限定されるものではなく、他の手段におきかえてもよい。
Below the drive shaft 50, a rotating brush 53 is disposed for removing foreign substances 61 and the like from the cylindrical comb 40. A top comb 30 is fixed to a driving arm (not shown) above the nip portion 51. The top comb 30 is also provided with a brush 52 for removing foreign substances 61 and the like. In the following description, a brush or a rotating brush is described as a means for removing impurities and the like. However, the present invention is not particularly limited to the brush, and other means may be used.
図10を参照して、ファイバータフト60がニップ部51によってつまみだされると、下方の駆動軸50が上昇し(50u)、シリンドリカルコーム40が、つまみだされたファイバータフト60の前半部分から夾雑物等61を梳る。
Referring to FIG. 10, when the fiber tuft 60 is picked up by the nip portion 51, the lower drive shaft 50 rises (50 u), and the cylindrical comb 40 is contaminated from the first half of the picked-up fiber tuft 60. Beat the object 61 or the like.
次に図11を参照して、ファイバータフト60は、シリンドリカルコーム40に梳られる際に進行方向61に進み、ロール54a、54bによって、引き取られる。この際に、トップコーム30が下方に下がり(30d)、トップコーム30がファイバータフト60の後半部分の夾雑物等61を梳る。この時、駆動軸50は、下方に下がり(50d)、シリンドリカルコーム40が回転ブラシ53に当接する位置に戻る。
Next, referring to FIG. 11, the fiber tuft 60 advances in the traveling direction 61 when being pulled by the cylindrical comb 40 and is taken up by the rolls 54a and 54b. At this time, the top comb 30 is lowered downward (30d), and the top comb 30 scoops up the foreign matter 61 and the like in the latter half of the fiber tuft 60. At this time, the drive shaft 50 is lowered downward (50d) and returned to the position where the cylindrical comb 40 contacts the rotating brush 53.
次に図12を参照して、回転ブラシ53によってシリンドリカルコーム40の夾雑物等61は除去される。一方、トップコーム30も上方に戻る(30u)。その際にブラシ52がトップコーム30に当接するように突き出され(52p)、トップコーム30に絡みついた夾雑物等61を除去する。ファイバータフト60は、夾雑物等61が除去され、次の工程に送られる。これらの動作が繰り返される。なお、以上の駆動軸50やトップコーム30、ブラシ53の動作は、図示しない制御装置が、前後の工程との時間的同調を含めて制御する。
Next, referring to FIG. 12, contaminants 61 of the cylindrical comb 40 are removed by the rotating brush 53. On the other hand, the top comb 30 also returns upward (30u). At this time, the brush 52 is protruded so as to abut on the top comb 30 (52p), and the foreign matter 61 entangled with the top comb 30 is removed. The fiber tuft 60 is sent to the next process after removing impurities 61 and the like. These operations are repeated. The operations of the drive shaft 50, the top comb 30, and the brush 53 are controlled by a control device (not shown) including temporal synchronization with the preceding and following processes.
以上のコーミングの工程において、本発明の紡績針を用いたトップコーム30およびシリンドリカルコーム40は、紡績針1が薄肉部9を有するため、夾雑物等の脱離性が従来の紡績針より高い。従って、従来のコーマの運転速度より速い速度であっても、夾雑物等のつまりなくコーミングを行うことができる。
In the above combing process, the top comb 30 and the cylindrical comb 40 using the spinning needle of the present invention have higher detachability of contaminants and the like than the conventional spinning needle because the spinning needle 1 has the thin portion 9. Therefore, even at a speed higher than the operation speed of the conventional comber, combing can be performed without any clogging of impurities.
なお、本発明のトップコームおよびシリンドリカルコームは、従来のトップコームおよびシリンドリカルコームと同様の位置に取り付けることができ、運転速度だけを高くして、使用することができる。本発明のトップコームおよびシリンドリカルコームは従来用いられている紡績針と大きく形状が変わっていないからである。
In addition, the top comb and the cylindrical comb of the present invention can be attached at the same position as the conventional top comb and the cylindrical comb, and can be used at a high operating speed. This is because the top comb and the cylindrical comb of the present invention are not greatly changed in shape from conventionally used spinning needles.
本発明は、繊維をコーミングする際のコーマに好適に利用することができる。
