Abstract

PROBLEM TO BE SOLVED: To propose a method for winding a wire bundle in which a plurality of wires are aligned in parallel to each other, on a driving pulley and/or a driven pulley and uniformly delivering the respective wires in the wire bundle.SOLUTION: A method for winding a wire bundle in which a plurality of wires are aligned in parallel, on a driving pulley and/or a driven pulley for delivering the wire bundle, includes placing a travel path of the wire bundle on the driving pulley and/or the driven pulley on the same straight line perpendicular to a rotary shaft of the driving pulley and/or the driven pulley.

Description

本発明は、複数本のスチールワイヤを並列に引き揃えたワイヤ束の搬送経路において、次の工程にワイヤ束を送り出すための方法およびその装置に関する。ここで、ワイヤ束を構成するワイヤとしては、スチール又は化学繊維のフィラメントを撚り合わせたコード、或いはスチール又は化学繊維のモノフィラメントなどを適用できる。   The present invention relates to a method and an apparatus for feeding a wire bundle to the next step in a wire bundle conveyance path in which a plurality of steel wires are arranged in parallel. Here, as the wire constituting the wire bundle, a cord in which filaments of steel or chemical fiber are twisted, or a monofilament of steel or chemical fiber can be applied.

さて、コンベアベルトや空気入りタイヤを典型例とする、工業用ゴム製品はスチールワイヤ（以下、単にワイヤと示す）などにて補強されるのが一般的である。例えば、空気入りタイヤにおいて、カーカスは勿論、ベルトやチェーファーはスチールワイヤの多数本をゴム被覆した、ゴム引き布からなるのが一般的である。   Industrial rubber products, typically conveyor belts and pneumatic tires, are typically reinforced with steel wires (hereinafter simply referred to as wires). For example, in a pneumatic tire, a belt and a chafer, as well as a carcass, are generally made of a rubberized cloth in which many steel wires are covered with rubber.

ここに、ベルトのとりわけ幅方向端を基点とするセパレーションの進展を抑制する観点から、ワイヤの複数本を並列に引き揃えて束化し、ベルト層でのワイヤの打ち込み数が同じ場合において、ワイヤ相互のベルト幅方向間隔を広くして、上記したセパレーションの進展を抑制することが提案されている（例えば、特許文献１参照）。   Here, from the viewpoint of suppressing the separation of the belt, particularly from the end in the width direction, when a plurality of wires are bundled in parallel and bundled and the number of wires driven in the belt layer is the same, It has been proposed to increase the separation in the belt width direction to suppress the above-described progress of separation (see, for example, Patent Document 1).

ここで、ワイヤの複数本を並列に引き揃えたワイヤ束にて補強したベルトプライは、ワイヤ束の複数本を所定間隔の下でカレンダー工程に供給し、これらをゴムシートで被覆して得られる。このカレンダー工程において、ワイヤ束はそれぞれ巻取リールから巻き出されて供給される。従って、ワイヤ束は、その束化後に巻取リールへ送り出されて巻取リールにて巻き取られ、その後、ワイヤ束が巻き取られた巻取リールをカレンダー工程に供することになる。   Here, the belt ply reinforced with a wire bundle in which a plurality of wires are arranged in parallel is obtained by supplying a plurality of wire bundles to a calender process under a predetermined interval and covering them with a rubber sheet. . In this calendar process, the wire bundles are unwound from the take-up reel and supplied. Therefore, the wire bundle is fed to the take-up reel after being bundled and taken up by the take-up reel, and then the take-up reel on which the wire bundle is taken up is subjected to a calendar process.

このワイヤ束の巻取リールへの送り出しは、例えば図１に示すように、一対の従動プーリ10及び駆動プーリ11間に、ワイヤ束１を螺旋状に複数条（図示例で５条：図１（ｂ）参照）にわたって巻き回して掛け渡すことにより、必要な駆動力を確保して行われていた。   For example, as shown in FIG. 1, a wire bundle 1 is spirally wound between a pair of driven pulleys 10 and a drive pulley 11, as shown in FIG. The necessary driving force is ensured by winding and wrapping over (see (b)).

特許第2713806号公報Japanese Patent No. 2713806

上記した、ワイヤ束１に駆動力を付与する方法は、図１（ｂ）に示したように、ワイヤ束１が螺旋状に複数回巻き付けられているため、ワイヤ束１に対して横方向（プーリ軸方向）の力（同図中の矢印）が加わり、各プーリとワイヤ束との接触面上にて、ワイヤの束がばらけたり片寄ることが頻発していた。このような現象が生じると、送り出し先の巻取リールに巻き取る際に、束内のワイヤ相互間で均等に巻き取ることが難しくなり、束内のワイヤ相互間で巻付け長さに差が生じることになる。そして、巻取リールにおいてワイヤ相互で巻付け長さに差があると、上記したカレンダー工程において巻取リールからワイヤ束を引き出して使用する際に、特定のワイヤに弛みが生じ健全な生産を続行できなくなることが問題になっていた。   The method for applying the driving force to the wire bundle 1 described above is because the wire bundle 1 is spirally wound a plurality of times as shown in FIG. A force (in the direction of the pulley axis) (arrow in the figure) was applied, and the wire bundles were often scattered or offset on the contact surface between each pulley and the wire bundle. When such a phenomenon occurs, it becomes difficult to wind evenly between the wires in the bundle when winding on the take-up take-up reel, and there is a difference in the winding length between the wires in the bundle. Will occur. And if there is a difference in winding length between the wires in the take-up reel, when the wire bundle is pulled out from the take-up reel and used in the calendar process described above, the specific wire becomes slack and continues sound production. It became a problem to become impossible.

そこで、本発明は、ワイヤの複数本を並列に引き揃えたワイヤ束を駆動プーリ及び従動プーリの対に通して、該束内のワイヤ相互を均等に送り出すための方途について提案することを目的とする。   Therefore, the present invention has an object to propose a method for passing a wire bundle in which a plurality of wires are arranged in parallel through a pair of a driving pulley and a driven pulley and feeding the wires in the bundle equally. To do.

発明者らは、ワイヤの複数本を並列に引き揃えたワイヤ束、すなわち撚り合わせることなく無拘束にて纏められたワイヤの束を、駆動プーリ及び従動プーリの対に通して送り出しのための駆動力を付与する際に、ワイヤ相互を均等に送り出すためには、駆動プーリ及び従動プーリへのワイヤ束の巻き回しを工夫することが有効であることを解明し、本発明を完成するに到った。
すなわち、在来の手法では、図１（ｂ）に示したように、駆動プーリ11及び従動プーリ10の対にワイヤ束１を複数条掛け回すことにより、束内でのワイヤの送り出し長さに差が発生することから、掛け回し条数を１条未満の掛け回しとし、プーリ回転軸と直交する向きから視たとき、ワイヤ束の巻き付け位置と巻き出し位置が一直線上に載るようにワイヤ束を掛け回して巻取リールへの送り出しを行ったところ、巻取リールに巻き取られたワイヤ束は、その束内のワイヤ相互での巻き付け長さ差が抑制されることが判明した。 The inventors have driven a wire bundle in which a plurality of wires are arranged in parallel, that is, a bundle of wires bundled together without being twisted together, through a pair of a drive pulley and a driven pulley for delivery. In order to send the wires evenly when applying force, it has been clarified that it is effective to devise the winding of the wire bundle around the driving pulley and the driven pulley, and the present invention has been completed. It was.
That is, in the conventional method, as shown in FIG. 1 (b), a plurality of wire bundles 1 are wound around a pair of a drive pulley 11 and a driven pulley 10 to obtain a wire feed length in the bundle. Because of the difference, the number of the winding strips is set to be less than one, and the wire bundle is placed so that the winding position and the unwinding position of the wire bundle are placed in a straight line when viewed from the direction orthogonal to the pulley rotation axis. As a result, the wire bundle wound around the take-up reel was found to suppress the difference in winding length between the wires in the bundle.

本発明は上記した知見に基づくものであり、その要旨構成は、次のとおりである。

以下、本発明のワイヤ束の送り出し方法について、図面を参照して詳しく説明する。
本発明に従うワイヤ束の送り出しは、図２に示すように、少なくとも一対の従動プーリ２及び駆動プーリ３を用いて行う。ここで、従動プーリ２及び駆動プーリ３は、回転軸相互が並行となる配置とし、プーリ相互を近接配置する。なお、符号４は、駆動プーリ３を駆動するモータなどの駆動源である。 Hereinafter, the wire bundle feeding method of the present invention will be described in detail with reference to the drawings.
The wire bundle according to the present invention is sent out using at least a pair of driven pulley 2 and drive pulley 3 as shown in FIG. Here, the driven pulley 2 and the driving pulley 3 are arranged so that the rotation axes are parallel to each other, and the pulleys are arranged close to each other. Reference numeral 4 denotes a drive source such as a motor for driving the drive pulley 3.

本発明の方法では、上記した従動プーリ２及び駆動プーリ３へのワイヤ束１の巻き回しを、従動プーリ２の一周未満の領域に巻き付けてからワイヤ束１の向きを反転させ、次いで駆動プーリ３の一周未満の領域に巻き付けて、従動プーリ２から駆動プーリ３へＳ字状（又は反転Ｓ字状）に通すことを基本とする。なお、従動プーリ２と駆動プーリ３との位置を入れ替えて、ワイヤ束１を駆動プーリ３から従動プーリ２へ通してもよい。
その際、前記従動プーリ２及び駆動プーリ３におけるワイヤ束１の走行経路が、図２（ｂ）に示すように、従動プーリ２及び駆動プーリ３の回転軸と直交する同一直線Ｌ上に置くこと、すなわち、プーリ回転軸と直交する向きから視たとき（図２（ｂ）の上面図が対応）、ワイヤ束１の巻き付け位置Ｍ１と巻き出し位置Ｍ２が一直線上に載るようにワイヤ束１を掛け回し（以下、１条掛けともいう）、例えば巻取リールへの送り出しを行うことが肝要である。 In the method of the present invention, the winding of the wire bundle 1 around the driven pulley 2 and the driving pulley 3 is wound around an area of less than one turn of the driven pulley 2 and then the direction of the wire bundle 1 is reversed, and then the driving pulley 3 Basically, it is wound around an area of less than one round and passed from the driven pulley 2 to the driving pulley 3 in an S shape (or an inverted S shape). Note that the positions of the driven pulley 2 and the driving pulley 3 may be interchanged so that the wire bundle 1 is passed from the driving pulley 3 to the driven pulley 2.
At that time, the traveling path of the wire bundle 1 in the driven pulley 2 and the driving pulley 3 is placed on the same straight line L orthogonal to the rotation axes of the driven pulley 2 and the driving pulley 3 as shown in FIG. , i.e., when viewed from the direction perpendicular to the pulley rotation axis (top view of FIG. 2 (b) is supported), the wire bundle so that the positions M 1 and unwind position M 2 wrapped wire bundle 1 rests on a straight line It is important to wrap around 1 (hereinafter also referred to as “single stake”), for example, to feed to a take-up reel.

上記に従ってワイヤ束１を一条に掛け回すことによって、従前のワイヤ束１の複数条掛けにて発生していたプーリ軸方向の力が加わることはなくなり、各プーリとワイヤ束との接触面上にて、ワイヤの束がばらけたり片寄ることがなくなる結果、束内ワイヤ間での均等な送り出しが実現される。   By winding the wire bundle 1 in a single line according to the above, the force in the pulley axial direction generated by the plurality of pieces of the conventional wire bundle 1 is not applied, and on the contact surface between each pulley and the wire bundle. As a result, the bundle of wires is not scattered or offset, and as a result, uniform feeding between the wires in the bundle is realized.

なお、一対の従動プーリ２及び駆動プーリ３を用いてワイヤ束１を確実に送り出すには、図３に示す、主に駆動プーリ３に対する、ワイヤ束１の各プーリに対する巻き付け領域を弧としたときの中心角度で定義される、巻付け角度θを調整、つまり角度θを大きくすることが好ましい。   In order to reliably feed the wire bundle 1 using the pair of driven pulleys 2 and the drive pulley 3, when the winding region of each pulley of the wire bundle 1 with respect to the drive pulley 3 shown in FIG. It is preferable to adjust the winding angle θ, which is defined by the center angle, that is, to increase the angle θ.

ここで、図３に示すような、一対の従動プーリ２及び駆動プーリ３を用いる場合は、ワイヤ束１の巻き付け位置Ｍ１と巻き出し位置Ｍ２とにおける張力を同等にして、巻付け角度θが小さくても駆動力を確保することが好ましい。すなわち、巻き付け位置Ｍ１における張力をＴ０、巻き出し位置Ｍ２における張力をＴ１、プーリ及びワイヤ束間の摩擦係数をμ、巻付け角度をθとするとき、ベルト（ワイヤ束）とプーリに関するオイラーの公式
Ｔ１＝Ｔ０×ｅμθ
から、前記の張力Ｔ０及び張力Ｔ１を同等にすれば、巻付け角度θが小さくても駆動力を確保できる。 Here, when a pair of driven pulley 2 and drive pulley 3 as shown in FIG. 3 are used, the tension at the winding position M 1 and the unwinding position M 2 of the wire bundle 1 is made equal, and the winding angle θ It is preferable to ensure the driving force even when the is small. That is, when the tension at the winding position M 1 is T 0 , the tension at the winding position M 2 is T 1 , the friction coefficient between the pulley and the wire bundle is μ, and the winding angle is θ, the belt (wire bundle) and the pulley Euler's formula for T 1 = T 0 × e μθ
Therefore, if the tension T 0 and the tension T 1 are made equal, the driving force can be secured even if the winding angle θ is small.

さらに、従動プーリ２及び駆動プーリ３は、ワイヤ束の巻付け角度θを大きく確保できる配置とすることが好ましい。例えば、図４に示す、プーリ配置が推奨される。   Furthermore, it is preferable that the driven pulley 2 and the driving pulley 3 are arranged so as to ensure a large winding angle θ of the wire bundle. For example, the pulley arrangement shown in FIG. 4 is recommended.

また、上述のとおりワイヤ束をプーリに対して１条掛けとする場合は、巻付け角度θを大きくし難いため、図５に示す、駆動プーリ３と従動プーリ２とが互い違いに配置された、複数対のプーリにワイヤ束１を順次掛け回し、結果として掛け段数を増やすことでワイヤ束１に付与する駆動力を確保することが、実施に当たってとりわけ有利である。すなわち、ワイヤ束１の巻き付け側と巻き出し側の張力差を吸収するために、従動プーリ２と駆動プーリ３とを互い違いに配置し、それらに交互にワイヤ束１を掛けまわすことが好ましい。なお、図５において符号５は、案内プーリである。   Further, as described above, when the wire bundle is hooked on the pulley, it is difficult to increase the winding angle θ. Therefore, the driving pulley 3 and the driven pulley 2 shown in FIG. 5 are alternately arranged. It is particularly advantageous in practice to secure the driving force to be applied to the wire bundle 1 by sequentially winding the wire bundle 1 around a plurality of pairs of pulleys and consequently increasing the number of stages. That is, in order to absorb the tension difference between the winding side and the unwinding side of the wire bundle 1, it is preferable that the driven pulley 2 and the driving pulley 3 are alternately arranged and the wire bundle 1 is alternately wound around them. In FIG. 5, reference numeral 5 denotes a guide pulley.

以上に説明した例では、駆動プーリと従動プーリとを組み合わせてワイヤ束を送り出しているが、駆動プーリ及び従動プーリのいずれか一方を単独で使用してもよい。すなわち、駆動プーリに巻き付けて駆動プーリの駆動力にてワイヤ束を送り出す場合は、ワイヤ束の走行経路が、駆動プーリの回転軸と直交する同一直線上に置くことが重要であるのは勿論である。これは、従動プーリの単独使用においても同様である。なお、従動プーリを単独で使用する場合は、従動プーリの入側の巻出しリール並びに、出側の巻取りリールによって、従動プーリにおける駆動力を調節することが可能である。   In the example described above, the wire bundle is sent out by combining the driving pulley and the driven pulley, but either one of the driving pulley or the driven pulley may be used alone. In other words, when the wire bundle is sent out by the driving force of the driving pulley after being wound around the driving pulley, it is important that the traveling path of the wire bundle is placed on the same straight line perpendicular to the rotation axis of the driving pulley. is there. The same applies to the single use of the driven pulley. When the driven pulley is used alone, the driving force in the driven pulley can be adjusted by the take-out reel on the inlet side of the driven pulley and the take-up reel on the outlet side.

本発明の方法の効果を確認するために、図２に示したところに従う１条掛けについて、スチールフィラメント（0.225mmφ）をワイヤとし該ワイヤの６本を並列に引き揃えたワイヤ束内のワイヤ間での送り出し量差を評価した。すなわち、図２に示したところに従って１条掛けしたワイヤ束を、巻取リールに送り出して巻取り、該巻取リールに巻き取られたワイヤの長さの差にて評価した。
ここで、本発明に従う１条掛けを評価するために、図２において巻き付け位置Ｍ１における張力Ｔ０と巻き出し位置Ｍ２における張力Ｔ１とを、それぞれ23.5Ｎと同じにした。なぜなら、オイラーの式より、Ｔ０とＴ１とを同じにすることにより、小さい巻付け角θで駆動力を確保できるからである。その際の駆動プーリ３における巻付け角度θは155°であった。 In order to confirm the effect of the method of the present invention, between the wires in a wire bundle in which a steel filament (0.225 mmφ) is used as a wire and six of the wires are aligned in parallel with respect to one strip according to FIG. The difference in the delivery amount was evaluated. That is, according to what was shown in FIG. 2, the wire bundle hung on one line was sent out and wound up to the winding reel, and it evaluated by the difference in the length of the wire wound up by this winding reel.
Here, in order to evaluate the Article 1 seat according to the present invention, the tension T 1 at the position M 2 unwinding the tension T 0 at the position M 1 wound 2 was the same as 23.5N respectively. This is because the driving force can be secured with a small winding angle θ by making T 0 and T 1 the same from Euler's equation. At that time, the winding angle θ of the drive pulley 3 was 155 °.

また、比較として、図１に示したところに従って、ワイヤ束を一対の駆動プーリと従動プーリに８条掛けで巻き回して送り出しを行った。
比較方法は、それぞれ、送り出したワイヤ束をひとつの巻取リールに（複数本同時に）長さ1,000ｍにわたって巻き取り、そのうちの設備減速部を除いた100mを引出し、巻き付けられたワイヤ束につきワイヤ毎に巻き付いた巻長さを測定し、ワイヤ相互間での巻長さの差を求めた。その結果を、８条掛けの場合を図６に、１条掛けの場合を図７に、それぞれ示す。まず、図６に示すように、８条掛けの場合は、一番長く巻かれていたワイヤの巻長さと一番短く巻かれていたワイヤの巻長さとの差が10.7mmであったのに対して、８条掛けの場合のそれは図７に示すように、2.8mmであった。 Further, as a comparison, the wire bundle was wound around the pair of driving pulleys and driven pulleys with eight lines and sent out as shown in FIG.
The comparison method is to wind the wire bundles sent out to one take-up reel (simultaneously) over a length of 1,000 m, pull out 100 m of them excluding the equipment speed reduction part, and wire for each wire bundle wound. The winding length wound around the wire was measured, and the difference in winding length between the wires was determined. The results are shown in FIG. 6 for the case of 8 lines and in FIG. 7 for the case of 1 line. First, as shown in FIG. 6, in the case of 8 hangs, the difference between the winding length of the longest wound wire and the winding length of the shortest wound wire was 10.7 mm. On the other hand, as shown in FIG.

さらに、図５に示したところに従って、ワイヤ束を５対の駆動プーリと従動プーリに多段で巻き回して送り出しを行った。ここで、巻き付け位置Ｍ１における張力Ｔ０：
23.5N及び、巻き出し位置Ｍ２における張力Ｔ１：23.5Nの下、各対での巻付け角度θは180°とした。そして、上記と同様に、巻取リールに（複数本同時に）長さ1,000ｍにわたって巻き取り、そのうちの設備減速部を除いた100mを引出し、巻き付けられたワイヤ束につきワイヤ毎に巻き付いた巻長さを測定し、ワイヤ相互間での巻長さの差を求めた。その結果を、図８に示すように、一番長く巻かれていたワイヤの巻長さと一番短く巻かれていたワイヤの巻長さとの差は2.4mmであった。 Furthermore, in accordance with what was shown in FIG. 5, the wire bundle was wound around 5 pairs of drive pulleys and driven pulleys in multiple stages and sent out. Here, the tension T 0 at the winding position M 1 :
The winding angle θ of each pair was 180 ° under 23.5 N and the tension T 1 at the unwinding position M 2 : 23.5 N. In the same manner as described above, the winding length is wound on a winding reel (simultaneously) over a length of 1,000 m, 100 m of the equipment speed reduction part is drawn out, and the wound length is wound for each wire in the wound wire bundle. Was measured, and the difference in winding length between the wires was determined. As a result, as shown in FIG. 8, the difference between the winding length of the wire wound the longest and the winding length of the wire wound the shortest was 2.4 mm.

以上の実施例では、スチールワイヤによるワイヤ束の送り出しについて説明したが、ワイヤ束としては化学繊維のワイヤによるものに対しても、本願発明を適用することができるのは勿論である。   In the above embodiment, the wire bundle feeding by the steel wire has been described, but the present invention can of course be applied to a wire bundle made of a chemical fiber wire.
