Description
本発明は、横編機に用いられる複合針に関する。 The present invention relates to a compound needle used in a flat knitting machine.
横編機の編針として、互いに前後方向へ相対移動する針本体及びスライダーを備えた複合針が用いられることがある。この複合針は、横編機の針床の針溝間に収容されている。また、スライダーは、スライダー基体と、このスライダー基体に支持され、互いに重ね合わせた２枚のブレードとを有し、これらのブレードが針本体の歯口側（前側）を前後方向へ延びるスライダー溝に摺動自在に収容されている。この場合、各ブレードを針本体のフック先端の側面部分に当接させて進出することで左右に分岐させ、フックを越えて進出したブレード間に、これと対向する針床の編針を進出させることで、目移しを行うようにしている。 As a knitting needle of a flat knitting machine, a compound needle having a needle body and a slider that move relative to each other in the front-rear direction may be used. This compound needle is accommodated between the needle grooves of the needle bed of the flat knitting machine. Further, the slider has a slider base and two blades supported by the slider base and overlapped with each other, and these blades are formed in slider grooves extending in the front-rear direction on the mouth side (front side) of the needle body. It is slidably accommodated. In this case, each blade is brought into contact with the side surface of the hook tip of the needle body to advance and branch to the left and right, and the knitting needle on the needle bed facing this is advanced between the blades that have advanced beyond the hook. So I'm trying to transfer.
しかし、スライダーを進出させて各ブレードを左右に開かせる複合針では、目移しなどを行う際に編糸がフックと擦れたりして各ブレード間に風綿等の塵埃が発生し易い。このため、塵埃が編針のフックに付着したりその周辺に堆積したりする。 However, in a compound needle that advances the slider and opens each blade to the left and right, the knitting yarn rubs against the hook when transferring and the like, and dust such as fluff is easily generated between the blades. For this reason, dust adheres to the hook of the knitting needle or accumulates in the vicinity thereof.
かかる点から、従来より、各ブレード間にゴミ取りプレートを設けたものが提案されている（特許文献１参照）。 From this point of view, there has been conventionally proposed a dust removing plate provided between the blades (see Patent Document 1).
ところで、フックに付着した塵埃やその周辺に堆積した塵埃は、ゴミ取りプレートの有無にかかわらず、針本体及びスライダーの前後方向への相対移動に伴って針本体の後側へ順次送られる傾向にある。 By the way, the dust adhering to the hook and the dust accumulated around it tend to be sequentially sent to the rear side of the needle body with the relative movement of the needle body and the slider in the front-rear direction regardless of the presence or absence of the dust removal plate. is there.
その場合、各ブレードのうちの少なくとも一方に、スライダーの移動時に略円弧状に突出する湾曲部分を摺接させて摺動抵抗を付与する摺動抵抗付与板部が設けられることがある。この摺動抵抗付与板部の湾曲部分の一側方には、当該湾曲部分とスライダー本体又は他方のブレードとによって仕切られた空間が形成されている。この空間は、針本体の後側へ順次送られた塵埃が堆積し易く、堆積した塵埃によって湾曲部分の一側方へ膨らむ。しかし、この空間の一側方には、スライダー基体が存在するため、堆積した塵埃による空間の一側方への膨らみがスライダー基体との当接によって阻害されてしまう。これでは、空間が湾曲部分の他側方（空間とは逆方向）へ膨らんでしまい、湾曲部分の摺接抵抗が大きくなって、複合針の動きが悪くなる。このため、複合針の動きを円滑に保つ上で、堆積した塵埃によって空間が他側方へ膨らむ前に当該空間内から塵埃を除去する作業を行う必要がある。 In that case, at least one of the blades may be provided with a sliding resistance applying plate portion that applies sliding resistance by sliding contact with a curved portion protruding in a substantially arc shape when the slider moves. A space partitioned by the curved portion and the slider body or the other blade is formed on one side of the curved portion of the sliding resistance applying plate portion. In this space, the dust sequentially sent to the rear side of the needle body easily accumulates, and the accumulated dust expands to one side of the curved portion. However, since there is a slider base on one side of this space, swelling of the space to one side due to accumulated dust is hindered by contact with the slider base. As a result, the space swells to the other side of the curved portion (in the opposite direction to the space), the sliding contact resistance of the curved portion increases, and the movement of the compound needle worsens. For this reason, in order to keep the movement of the compound needle smoothly, it is necessary to perform an operation of removing dust from the space before the space is expanded to the other side by accumulated dust.
本発明の目的は、堆積した塵埃によって空間を他側方へ膨らみ難くして、空間内からの塵埃の除去作業を遅延させることができる横編機の複合針を提供することにある。 An object of the present invention is to provide a compound needle for a flat knitting machine that makes it difficult for the accumulated dust to bulge to the other side due to accumulated dust and delays the work of removing dust from the space.
前記目的を達成するため、本発明では、横編機の針床の針溝間に収容されて互いに前後方向へ相対移動する針本体及びスライダーを備え、前記スライダーが、スライダー基体と、このスライダー基体に支持され、前記針本体の歯口側を前後方向へ延びるスライダー溝に摺動自在に収容されてそれぞれ後方へ延びる２枚のブレードと、この各ブレードのうちの少なくとも一方の後端に一体又は別体で連設されて後方へ延び、前記スライダーの移動時に略円弧状に湾曲する湾曲部分が摺接して摺動抵抗を付与する摺動抵抗付与板部と、前記スライダー基体に設けられ、前記摺動抵抗付与板部の前後両端のうちのいずれか一方を一側方から固定する固定部及び他方を一側方から摺接させる摺接部と、を有してなる複合針を前提とする。そして、前記スライダー基体に、前記固定部と前記摺接部とを前記湾曲部分の上方又は下方を延びて連結する連結部を設け、この連結部は、前記湾曲部分の一側方が切除されている。更に、前記湾曲部分と前記連結部との間には、隙間が設けられていることを特徴としている。
In order to achieve the above object, the present invention comprises a needle body and a slider which are accommodated between needle grooves of a needle bed of a flat knitting machine and move relative to each other in the front-rear direction. The slider includes a slider base and the slider base. Or two blades slidably received in a slider groove extending in the front-rear direction on the side of the mouth of the needle body and extending rearward, and at least one of the blades integrated with a rear end A sliding resistance application plate portion that is provided in a separate body and extends rearward, and a curved portion that is curved in a substantially arc shape when the slider is moved to slide to provide sliding resistance; and is provided on the slider base, It is premised on a compound needle having a fixed portion that fixes one of the front and rear ends of the sliding resistance imparting plate portion from one side and a sliding contact portion that slides the other from one side. . The slider base is provided with a connecting portion for connecting the fixed portion and the sliding contact portion extending above or below the curved portion, and the connecting portion is cut off at one side of the curved portion. Yes . Furthermore, a gap is provided between the curved portion and the connecting portion .
また、前記摺動抵抗付与板部を、前記各ブレードのうちの一方の後端にのみ連設することが好ましい。 Further, it is preferable that the sliding resistance applying plate portion is provided continuously only at one rear end of each of the blades.
更に、前記摺接部、又は前記摺接部に摺接する前記摺動抵抗付与板部に、切欠部又は孔部を設けることが好ましい。 Furthermore, it is preferable to provide a notch or a hole in the sliding contact portion or the sliding resistance applying plate portion that is in sliding contact with the sliding contact portion.
本発明によれば、スライダー基体の固定部と摺接部とを連結する連結部は、湾曲部分の一側方を切除することで、塵埃の堆積による湾曲部分の一側方への空間の膨らみがスライダー基体によって阻害されることがない。これにより、空間が他側方へ膨らみ難くなって複合針の動きが円滑に保たれ、空間内からの塵埃の除去作業を遅延させることができる。
しかも、固定部と摺接部とを湾曲部分の上方又は下方を延びる連結部により連結することで、固定部と摺接部との前後方向の間隔を連結部の長さに応じて任意に設定することが可能となる。これにより、摺動抵抗付与板部の湾曲部分の前後長を長くすることができ、ニードルプレートに対する湾曲部分の摺動抵抗を容易に設定することができる。
また、摺動抵抗付与板部の湾曲部分とスライダー基体の連結部との間に隙間を設けることで、空間に堆積した塵埃が隙間を介して排出され易く、空間内の塵埃の除去作業をさらに遅延させることができる。
According to the present invention, the connecting portion that connects the fixed portion of the slider base and the sliding contact portion cuts one side of the curved portion, so that the space bulges to one side of the curved portion due to dust accumulation. Is not disturbed by the slider substrate. As a result, the space is less likely to bulge to the other side, the movement of the compound needle is maintained smoothly, and the dust removal operation from the space can be delayed.
In addition, by connecting the fixed portion and the sliding contact portion with a connecting portion extending above or below the curved portion, the interval in the front-rear direction between the fixed portion and the sliding contact portion is arbitrarily set according to the length of the connecting portion. It becomes possible to do. Thereby, the front-rear length of the curved portion of the sliding resistance applying plate portion can be increased, and the sliding resistance of the curved portion with respect to the needle plate can be easily set.
In addition, by providing a gap between the curved portion of the sliding resistance applying plate portion and the connecting portion of the slider base, dust accumulated in the space can be easily discharged through the gap, and the dust in the space can be further removed. Can be delayed.
また、摺動抵抗付与板部を一方のブレードにのみ連設することで、摺動抵抗付与板部の湾曲部分の一側方の空間が、その一側方のニードルプレートまで拡張される。その上、空間内で堆積した塵埃がスライダーの摺動に伴って前後に移動する。このため、空間内の塵埃が逃げ易くなる上、空間へ塵埃が堆積しても当該空間を満たすまでに十分な時間を稼げる。これにより、空間内の塵埃の除去作業をより遅延させることができる。 Further, by connecting the sliding resistance applying plate portion to only one blade, the space on one side of the curved portion of the sliding resistance applying plate portion is expanded to the needle plate on the one side. In addition, the dust accumulated in the space moves back and forth as the slider slides. For this reason, dust in the space can easily escape, and even if dust accumulates in the space, a sufficient time can be taken to fill the space. Thereby, the removal operation | work of the dust in space can be delayed more.
更に、摺接部、又は摺接部に摺接する摺動抵抗付与板部の前後両端のうちの他方に、切欠部又は孔部を設けることで、空間に塵埃が堆積しても、その堆積した塵埃が摺動抵抗付与板部の切欠部又は孔部から排出され易い。これにより、空間内の塵埃の除去作業をより一層遅延させることができる。 Furthermore, even if dust accumulates in the space by providing a notch or a hole on the other of the sliding contact portion or the front and rear ends of the sliding resistance imparting plate portion that is in sliding contact with the sliding contact portion Dust is easily discharged from the notch or hole of the sliding resistance imparting plate. Thereby, the removal operation | work of the dust in space can be delayed further.

ここで、第１の実施の形態の変形例を図４に基づいて説明する。
図４の（ａ）は複合針のブレード付近の拡大側面図、（ｂ）は複合針の摺動抵抗付与板部付近の底面図をそれぞれ示している。なお、摺動抵抗付与板部及び延設部を除くその他の構成は、第１の実施の形態と同じであるので、摺動抵抗付与板部及び延設部の構成についてのみ説明する。
Here, the modification of 1st Embodiment is demonstrated based on FIG.
4A is an enlarged side view of the vicinity of the composite needle blade, and FIG. 4B is a bottom view of the vicinity of the sliding resistance applying plate portion of the composite needle. In addition, since the structure other than a sliding resistance provision board part and an extension part is the same as 1st Embodiment, only the structure of a sliding resistance provision board part and an extension part is demonstrated.
すなわち、図４に示すように、スライダー３は、摺動抵抗付与板部３７を備えている。この摺動抵抗付与板部３７の前端は、各ブレード３２，３３のうちの一方（図４の（ａ）では紙面奥側）のブレード３２の後端に一体に連設されて後方へ延びている。また、他方（図４の（ａ）では紙面手前側）のブレード３３は、固定部４３で一方のブレード３２と共に後端がかしめ固定されている。この場合、他方のブレード３３の後端には延設部がない。 That is, as shown in FIG. 4, the slider 3 includes a sliding resistance imparting plate portion 37.
