Description

本発明は鋼線長さの評価方法、鋼線の巻取方法および巻取製品(以下、単に「評価方法」および「巻取方法」とも称する)に関し、詳しくは、複数本にて引き揃えられた鋼線の束を構成する各鋼線の長さを評価する方法、これを用いた鋼線の巻取方法および巻取製品に関する。   The present invention relates to a steel wire length evaluation method, a steel wire winding method, and a wound product (hereinafter, also simply referred to as “evaluation method” and “winding method”). The present invention relates to a method for evaluating the length of each steel wire constituting a bundle of steel wires, a method for winding a steel wire using the steel wire, and a wound product.

従来より、タイヤ等のゴム物品の補強材としては、鋼線を複数本にて撚り合わせた撚りコードが用いられており、また、鋼線を撚り合わせずに用いたモノフィラメントコードの適用についても、種々検討されてきている。このうち、鋼線を複数本にて撚り合わせずに引き揃えてなるモノフィラメントコードを用いて補強材を作製する際には、各鋼線を別個のスプールから引き出し引き揃えてゴム被覆する手法の他、複数本の鋼線をあらかじめ引き揃えて単一のスプールに巻き取っておき、この単一のスプールから鋼線束として引き出す手法が考えられる。   Conventionally, as a reinforcing material for rubber articles such as tires, twisted cords in which a plurality of steel wires are twisted are used, and also about the application of monofilament cords that are used without twisting steel wires, Various studies have been made. Among these, when producing a reinforcing material using a monofilament cord in which a plurality of steel wires are drawn together without being twisted, each steel wire is drawn out from a separate spool, and the rubber coating is applied. A method is conceivable in which a plurality of steel wires are aligned in advance and wound on a single spool, and drawn out as a bundle of steel wires from this single spool.

後者の鋼線束を引き出す手法を用いる場合、鋼線束を構成する複数本の鋼線が、スプールに均等な長さで巻き取られていることが重要となる。すなわち、複数本の鋼線をカレンダー設備にてゴムシート中に埋設して補強材を製造する工程において、スプールに巻き付けられた鋼線束を巻出しスタンドから引き出す場合、鋼線束を構成する個々の鋼線の長さが均等でないと、引き出された鋼線の一部にたるみが生じて健全な生産を阻害するためである。   When using the latter method of pulling out the steel wire bundle, it is important that a plurality of steel wires constituting the steel wire bundle are wound around the spool with a uniform length. That is, in the process of manufacturing a reinforcing material by embedding a plurality of steel wires in a rubber sheet with a calendar facility, when pulling a steel wire bundle wound around a spool from an unwinding stand, the individual steels constituting the steel wire bundle This is because if the lengths of the wires are not uniform, sagging occurs in a part of the drawn steel wires, thereby hindering healthy production.

このように束としてスプールに巻き取られた複数本の鋼線の個々の長さの均等性を評価する方法としては、例えば、特許文献1に、鋼材の巻き長さばらつき評価に用いる室内しごき試験法として、カレンダー巻き出し同様の軸に3本束鋼線のスプールをセットし、約4m離れたところで手動しごきを施した状態で約100m引き出して、その時の約4m間でのたるみ巾とスプール端部の3本束残糸間の長さばらつきを測定する方法が開示されている。   As a method for evaluating the uniformity of individual lengths of a plurality of steel wires wound on a spool as a bundle in this way, for example, Patent Document 1 discloses an indoor ironing test used for evaluating the winding length variation of steel materials. As a method, set a spool of three bundles of steel wire on the same shaft as the calendar unwinding, pull it out about 100 m with manual ironing at a distance of about 4 m, and the slack width and spool end between about 4 m at that time A method for measuring the length variation between the three bundle remaining yarns of a part is disclosed.

特開2002−309492号公報(段落[0016],[0017])JP 2002-309492 A (paragraphs [0016], [0017])

しかしながら、上記特許文献1に記載の方法は、手動しごきを用いるものであるために、試験者がワイヤー束を把持する指先に苦痛を感じたり、把持力を一瞬でも弱めると集約させた鋼線の長さばらつきが開放されてしまうなどの難点を有するものであった。よって、このような問題を生ずることなく、簡易にかつ正確に、複数本の鋼線の個々の長さを評価することができる技術の確立が求められていた。   However, since the method described in Patent Document 1 uses manual ironing, the tester feels pain in the fingertip that grips the wire bundle, or if the gripping force is weakened even for a moment, the steel wires that are aggregated It has a drawback that length variation is released. Therefore, establishment of a technique that can easily and accurately evaluate individual lengths of a plurality of steel wires without causing such a problem has been demanded.

そこで本発明の目的は、複数本にて引き揃えられた鋼線の束を構成する各鋼線の長さを、簡易にかつ正確に評価することができる鋼線長さの評価方法を提供することにあり、また、この評価方法を用いることで、複数本の鋼線を誤差の少ないほぼ同一の長さで巻き取ることができる鋼線の巻取方法、および、これにより得られる巻取製品を提供することにある。   Then, the objective of this invention provides the evaluation method of the steel wire length which can evaluate easily and correctly the length of each steel wire which comprises the bundle of the steel wire arranged by multiple pieces. In addition, by using this evaluation method, a steel wire winding method capable of winding a plurality of steel wires with substantially the same length with little error, and a wound product obtained thereby Is to provide.

本発明者は鋭意検討した結果、鋼線束を2つの支持点間に掛け渡した状態で、鋼線束の一端を固定して他端に一定の張力を掛けたときの、各鋼線のなす曲線の最低高さと支持点の高さとの差を計測する手法を用いることで、上記課題が解決できることを見出して、本発明を完成するに至った。   As a result of intensive studies, the present inventors have determined that each steel wire has a curved line when one end of the steel wire bundle is fixed and a constant tension is applied to the other end while the steel wire bundle is spanned between two support points. The present invention has been completed by finding that the above-mentioned problems can be solved by using a method of measuring the difference between the minimum height and the height of the support point.

すなわち、本発明の鋼線長さの評価方法は、複数本にて引き揃えられた鋼線の束を構成する各鋼線の長さを評価する方法であって、
前記鋼線束を、水平方向距離Sの間隔を有しかつ同じ高さに位置する2つの支持点間に掛け渡した状態で、該鋼線束の一端を固定して他端に一定の張力を掛けたときの各鋼線のなす曲線の最低高さと前記支持点の高さとの差dを計測して、得られた計測値dに基づき、前記2つの支持点間における前記各鋼線の長さLを算出することを特徴とするものである。

以下、本発明の実施の形態について、図面を参照しつつ詳細に説明する。
本発明の鋼線長さの評価方法は、複数本、例えば、3〜12本にて引き揃えられた鋼線の束、特には、撚り合わされずに引き揃えられた鋼線束を構成する各鋼線の長さを評価する方法の改良に係るものである。図1に、本発明の鋼線長さの評価方法に係る概略説明図を示す。
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The steel wire length evaluation method of the present invention includes a plurality of, for example, three to twelve bundles of steel wires, in particular, each steel constituting a bundle of steel wires arranged without being twisted together. This relates to an improvement in the method for evaluating the length of a line. In FIG. 1, the schematic explanatory drawing which concerns on the evaluation method of the steel wire length of this invention is shown.

図示するように、本発明においては、鋼線束10を、水平方向距離Sの間隔を有し、かつ、同じ高さに位置する2つの支持点X−Y間に掛け渡した状態で、鋼線束10の一端(X側)を固定して、他端(Y側)に一定の張力Tを掛ける。このとき、図2に示すように、各鋼線1のなす曲線の最低高さと支持点の高さとの差(たるみ高さ)dを計測して、得られた計測値dに基づき、2つの支持点X−Y間における各鋼線1の長さLを算出するものである。   As shown in the figure, in the present invention, the steel wire bundle 10 is stretched between two support points XY having a horizontal distance S and located at the same height. One end (X side) of 10 is fixed, and a constant tension T is applied to the other end (Y side). At this time, as shown in FIG. 2, the difference (sag height) d between the minimum height of the curve formed by each steel wire 1 and the height of the support point is measured, and based on the obtained measurement value d, two The length L of each steel wire 1 between the support points XY is calculated.

本発明によれば、鋼線束10を構成する各鋼線につき上記たるみ高さを計測するのみで、算出式に基づき、個々の鋼線の長さを正確に、かつ、簡易に測定することができる。よって、この測定結果を用いることで、複数本の鋼線を誤差の少ないほぼ同一の長さで巻き取ることが可能となる。   According to the present invention, the length of each steel wire can be accurately and simply measured based on the calculation formula only by measuring the sagging height for each steel wire constituting the steel wire bundle 10. it can. Therefore, by using this measurement result, a plurality of steel wires can be wound up with substantially the same length with little error.

ここで、各鋼線の長さL(m)の具体的な算出には、例えば、下記式(1)、

Figure 2013087378
(式中、Sは前記2つの支持点間の水平方向距離(m)であり、dは前記各鋼線のなす曲線の最低高さと前記支持点の高さとの差(m)である)を用いることができる。上記式は、電線の架線において、2つの支持点に高低差がない場合に一般に用いられる式である。なお、1本の電線を支持点間に張る場合には、自重によるたるみを考慮して、使用する電線としては実際の支持点間よりも長い電線を用意する必要があるが、本発明においては、同じ線径、すなわち、同じ単位重量の複数本の鋼線の長さの差のみを計測することを目的とするので、各鋼線の自重によるたるみは無視することができる。厳密には、支持点間で長さ差があれば自重によるたるみ量は異なるが、本発明においては、その影響は極めて小さいと考えられる。 Here, for specific calculation of the length L (m) of each steel wire, for example, the following formula (1),
Figure 2013087378
(Wherein S is the horizontal distance (m) between the two support points, and d is the difference (m) between the minimum height of the curve formed by each steel wire and the height of the support points). Can be used. The above expression is an expression that is generally used when there is no difference in height between two support points in the wire overhead. In addition, when one electric wire is stretched between supporting points, it is necessary to prepare a longer electric wire than between actual supporting points in consideration of slack due to its own weight. Since the purpose is to measure only the difference in length of a plurality of steel wires having the same wire diameter, that is, the same unit weight, the sag due to the weight of each steel wire can be ignored. Strictly speaking, if there is a difference in length between the support points, the amount of sag due to its own weight is different, but in the present invention, the influence is considered to be extremely small.

本発明の評価方法において、2つの支持点X−Y間の距離Sは、特に制限されず、適宜設定することが可能であるが、測定の便宜の観点からは5〜20m程度が好ましく、算出のし易さを踏まえると、10mが最適である。   In the evaluation method of the present invention, the distance S between the two support points XY is not particularly limited and can be set as appropriate, but is preferably about 5 to 20 m from the viewpoint of convenience of measurement, and is calculated. Considering the ease of handling, 10m is optimal.

また、本発明の評価方法においては、鋼線束10の他端に掛ける張力Tの大きさについても特に制限されないが、好適には、鋼線の単位重量に鋼線束の構成本数を乗じ、さらに水平方向距離Sを乗じた値の10〜15倍の範囲とする。その理由は、鋼線の長さに違いがあった場合、張力が高過ぎると、相対的に短い鋼線に負荷が集中して、この鋼線が引き伸ばされ、相対的に長い鋼線のたるみ量が減少することになり、逆に張力が低過ぎると、全鋼線が大きくたるんでしまい、いずれの場合も精確な計測が困難となるためである。ここで、鋼線束10に張力を負荷するための手法については特に制限はなく、例えば、鋼線束10の他端に錘を吊り下げる手法などが挙げられる。   Further, in the evaluation method of the present invention, the magnitude of the tension T applied to the other end of the steel wire bundle 10 is not particularly limited, but preferably, the unit weight of the steel wire is multiplied by the number of steel wire bundles and further horizontal. The range is 10 to 15 times the value multiplied by the direction distance S. The reason is that if there is a difference in the length of the steel wire, if the tension is too high, the load will be concentrated on the relatively short steel wire and the steel wire will be stretched, and the slack of the relatively long steel wire This is because if the amount is reduced and the tension is too low, the entire steel wire is greatly slackened, and accurate measurement is difficult in either case. Here, there is no restriction | limiting in particular about the method for applying tension | tensile_strength to the steel wire bundle 10, For example, the method etc. which suspend a weight to the other end of the steel wire bundle 10 are mentioned.

本発明の評価方法は、より具体的には、1つのスプールに同時に巻き取られた複数本の鋼線の個々の長さを評価する際に有用である。すなわち、この場合、まず、複数本の鋼線束が巻き付けられたスプール11を、鋼線束の出線位置が支持点Xと一致するように、巻出しスタンド12にセットする。次いで、このスプール11から鋼線束10を引き出して、鋼線束の支持位置が支持点Yと一致するように引出しスタンド13にセットされたプーリ14に掛け回し、引出した端末側に、錘15を吊り下げるなどにより一定の水平張力Tを負荷する。ここで、スプール11側の巻出しスタンド12は、張力Tの負荷により鋼線束10が引き出されない程度の回転抵抗を備えるものとする。次いで、このときに生ずる各鋼線1のなす曲線の最低点と支持点X,Yとの高さの差(たるみd)を計測することで、この計測値(d)に基づき、各鋼線の実長さ(L)を算出することができる。   More specifically, the evaluation method of the present invention is useful when evaluating individual lengths of a plurality of steel wires wound simultaneously on one spool. That is, in this case, first, the spool 11 around which the plurality of steel wire bundles are wound is set on the unwinding stand 12 so that the outgoing position of the steel wire bundle coincides with the support point X. Next, the steel wire bundle 10 is pulled out from the spool 11 and hung around the pulley 14 set on the drawer stand 13 so that the support position of the steel wire bundle coincides with the support point Y, and the weight 15 is hung on the drawn end side. A constant horizontal tension T is applied by lowering. Here, the unwinding stand 12 on the spool 11 side is provided with a rotational resistance that does not allow the steel wire bundle 10 to be pulled out by the load of the tension T. Next, by measuring the height difference (sag d) between the lowest point of the curve formed by each steel wire 1 and the support points X, Y at this time, each steel wire is based on this measured value (d). The actual length (L) can be calculated.

なお、本発明の評価方法においては、鋼線束を引出す際に測定対象となる各鋼線の長さの差が開放されることを防止するために、鋼線束を引き出す前に、鋼線束の端部に近い一点で、鋼線同士をハンダで固着させておくことが好ましい。この際に用いるハンダとしては、作業環境面から鉛フリーが好ましいが、特に限定されるものではない。また、スプールへの鋼線の巻付け径が変化すると、鋼線束の出線位置の高さも変動する。この場合、ある程度の巻付け径の差は影響が小さいので無視することができるが、連続して計測を行う際には、スプールの取付け高さの調整を、適宜行うことが好ましい。具体的には例えば、出線位置の高さが3cm、すなわち、鋼線の巻付け半径が3cmずれる場合に、取付け高さの調整を行うものとすることができる。   In the evaluation method of the present invention, in order to prevent the difference in length of each steel wire to be measured when the steel wire bundle is drawn out, the end of the steel wire bundle is drawn before the steel wire bundle is drawn out. It is preferable to fix the steel wires with solder at one point close to the part. The solder used at this time is preferably lead-free from the viewpoint of work environment, but is not particularly limited. Further, when the winding diameter of the steel wire around the spool changes, the height of the outgoing wire position of the steel wire bundle also changes. In this case, the difference in the winding diameter to a certain extent can be ignored because the influence is small. However, when continuously measuring, it is preferable to appropriately adjust the mounting height of the spool. Specifically, for example, when the height of the outgoing line position is 3 cm, that is, when the winding radius of the steel wire is shifted by 3 cm, the attachment height can be adjusted.

また、本発明の評価方法において、鋼線長さを長手方向に繰り返し測定する場合などには、各鋼線の識別性を高めるために、各鋼線に異なる色彩や形状等を有する識別性の高い標識を付与することも好ましい。具体的には例えば、図3に示すように、各鋼線1に、引出し端末側より、鋼線ごとに色や形状等を変えたプラスチックビーズ16などの軽量で鋼線のたるみを助長しない円筒状物を通す手法や、マーカーで適宜目印を付ける手法などを用いることができる。これにより、計測を長手方向に繰り返す際において各鋼線の識別が容易となるので、各鋼線の長さを長手方向に連続して評価した結果を蓄積することで、より長尺の鋼線長さを求めることが可能となる。ここで、例えば、円筒状物を用いる場合には、評価の準備段階において、あらかじめ各鋼線の端部から各鋼線に円筒状物を挿入しておき、この円筒状物を、たるみ高さの計測時には2つの支持点間の中間点付近に位置させ、計測後にはスプール11側に移動させて、次の計測に備えるものとすればよい。   Further, in the evaluation method of the present invention, when repeatedly measuring the length of the steel wire in the longitudinal direction, etc., in order to improve the discriminability of each steel wire, the discriminating property having different colors, shapes, etc. It is also preferred to provide a high label. Specifically, for example, as shown in FIG. 3, each steel wire 1 is a lightweight cylinder such as plastic beads 16 whose color and shape are changed for each steel wire from the drawing terminal side, and does not promote slack in the steel wire. For example, a method of passing a material or a method of appropriately marking with a marker can be used. This makes it easy to identify each steel wire when repeating the measurement in the longitudinal direction, and by accumulating the results of continuous evaluation of the length of each steel wire in the longitudinal direction, a longer steel wire The length can be obtained. Here, for example, when a cylindrical object is used, in the preparation stage for evaluation, a cylindrical object is inserted in advance into each steel wire from the end of each steel wire, and this At the time of measurement, it is positioned near the intermediate point between the two support points, and after measurement, it is moved to the spool 11 side to prepare for the next measurement.

さらに、本発明の評価方法においては、鋼線長さの測定後に測定済みの鋼線長さ部分を切断してもよく、これにより、長尺の鋼線の長さを長手方向に繰り返し測定することが容易となる。   Furthermore, in the evaluation method of the present invention, the measured steel wire length portion may be cut after the measurement of the steel wire length, thereby repeatedly measuring the length of the long steel wire in the longitudinal direction. It becomes easy.

本発明において、評価対象となる鋼線とは、タイヤ等のゴム物品の補強材として用いられるスチールワイヤ(スチールフィラメント)の他、ピアノ線やステンレス線、合金線等のいかなる線材をも含むものである。   In the present invention, the steel wire to be evaluated includes any wire material such as a piano wire, a stainless steel wire, and an alloy wire, in addition to a steel wire (steel filament) used as a reinforcing material for rubber articles such as tires.

次に、本発明の鋼線の巻取方法は、複数本にて引き揃えられた鋼線の束をスプールに巻き取るにあたり、上記本発明の評価方法による各鋼線長さLの算出結果に基づき、鋼線束を構成する複数本の鋼線の長さを±0.01%以内、好適には±0.006%以内の誤差範囲で揃える点に特徴を有する。上述したように、本発明の評価方法によれば、1つのスプールに巻き付けられた複数本の鋼線の個々の長さを、ほぼ正確に評価することが可能となるので、この評価結果に基づくことで、複数本の鋼線を極めて誤差の少ないほぼ同一の長さでスプールに巻き取った巻取製品を得ることが可能となる。また、個々の鋼線の識別が可能であることから、測定毎の変動、すなわち、鋼線束の長手方向における各鋼線長さの変動が明確となるので、長さばらつきのメカニズムや、発生原因の特定が容易になるというメリットがある。   Next, the winding method of the steel wire of the present invention is based on the calculation result of each steel wire length L by the evaluation method of the present invention when winding a bundle of steel wires arranged in a plurality on a spool. On the basis of this, it is characterized in that the lengths of a plurality of steel wires constituting the steel wire bundle are aligned within an error range of within ± 0.01%, preferably within ± 0.006%. As described above, according to the evaluation method of the present invention, individual lengths of a plurality of steel wires wound around one spool can be evaluated almost accurately. This makes it possible to obtain a wound product obtained by winding a plurality of steel wires on a spool with substantially the same length with very little error. In addition, since individual steel wires can be identified, fluctuations in each measurement, that is, fluctuations in the length of each steel wire in the longitudinal direction of the steel wire bundle are clarified. There is a merit that it becomes easy to specify.

ここで、1つのスプールに巻き付けられた複数本の鋼線の個々の長さのバラツキを低減するための方法としては、例えば、鋼線束を駆動プーリおよび従動プーリの対に通して、鋼線束に送り出しのための駆動力を付与する際に、従動プーリないし駆動プーリにおける鋼線束の走行経路を、従動プーリないし駆動プーリの回転軸と直交する同一直線上に置く方法や、従動プーリおよび駆動プーリの、それぞれ一周未満の領域に鋼線束を巻き付けて鋼線束に駆動力を付与する際に、従動プーリおよび駆動プーリにおけるワイヤ束の走行経路を、従動プーリおよび駆動プーリの回転軸と直交する同一直線上に置く方法が挙げられる。これにより、複数本の鋼線のそれぞれに均等に駆動力を掛けることができるので、鋼線間における送り出し長さの差を発生させずに、鋼線束をスプールに巻き取ることが可能となるものである。   Here, as a method for reducing variation in individual lengths of a plurality of steel wires wound around one spool, for example, a steel wire bundle is passed through a pair of a driving pulley and a driven pulley to form a steel wire bundle. When applying the driving force for feeding, the travel route of the steel wire bundle in the driven pulley or the driving pulley is placed on the same straight line perpendicular to the rotation axis of the driven pulley or the driving pulley, or the driven pulley and the driving pulley When the steel wire bundle is wound around each of the regions less than one turn and the driving force is applied to the steel wire bundle, the traveling path of the wire bundle in the driven pulley and the driving pulley is on the same straight line perpendicular to the rotation axis of the driven pulley and the driving pulley. The method of putting in is mentioned. As a result, it is possible to apply a driving force evenly to each of the plurality of steel wires, so that the steel wire bundle can be wound on the spool without causing a difference in feed length between the steel wires. It is.

以下、本発明を、実施例を用いてより詳細に説明する。
<実施例1>
線径φ0.225mm、単位重量0.312g/mのスチールワイヤを6本にて撚り合わせずに引き揃えたスチールワイヤ束を巻き取ったスプールについて、各スチールワイヤ長さの評価を行った。まず、このスプールを巻出しスタンドにセットして、評価の準備段階として、各スチールワイヤに、色分けした玩具用プラスチックビーズを挿入した。
Hereinafter, the present invention will be described in more detail with reference to examples.
<Example 1>
The length of each steel wire was evaluated on a spool wound with a steel wire bundle in which steel wires having a wire diameter of 0.225 mm and a unit weight of 0.312 g / m were arranged without being twisted by 6 pieces. First, this spool was set on an unwinding stand, and color-coded plastic beads for toys were inserted into each steel wire as a preparation stage for evaluation.

評価手順としては、まず、1)スチールワイヤの引出し端部に近い一点で、スチールワイヤ同士をハンダで固定した。次いで、2)スチールワイヤの引出し端末を、引出しスタンドにセットされたプーリに掛け回した。ここで、スプール側の鋼線束の出線位置(支持点X)とプーリ側の鋼線束の支持位置(支持点Y)とが同じ高さに位置するようにした。2つの支持点X−Y間の距離Sは10mとした。この際、プラスチックビーズは2つの支持点間の中間点付近に位置させた。   As an evaluation procedure, first, 1) the steel wires were fixed with solder at one point close to the drawing end of the steel wires. Next, 2) the steel wire drawer terminal was hung around the pulley set on the drawer stand. Here, the outgoing line position (support point X) of the steel wire bundle on the spool side and the support position (support point Y) of the steel wire bundle on the pulley side are located at the same height. The distance S between the two support points XY was 10 m. At this time, the plastic beads were positioned near the midpoint between the two support points.

次いで、3)スチールワイヤの引出し端末側に250gの錘を掛けた。これは、下記式により得られる値A(g)に基づき、Aの10〜15倍の範囲で選択した張力(約13.4倍)である。なお、スプール側の巻出しスタンドは、上記張力の負荷によりスチールワイヤ束が引き出されない程度の回転抵抗を備えるものとした。
A=0.312(g/m)(鋼線の単位重量)×6(本)(鋼線束の構成本数)×10 (m)(水平方向距離)=18.72g
Next, 3) A 250 g weight was hung on the steel wire drawer terminal side. This is a tension (about 13.4 times) selected in a range of 10 to 15 times A based on the value A (g) obtained by the following formula. The spool-side unwinding stand is provided with a rotational resistance that prevents the steel wire bundle from being pulled out due to the tension load.
A = 0.312 (g / m) (unit weight of steel wire) x 6 (pieces) (number of steel wire bundles) x 10 (m) (horizontal distance) = 18.72g

次いで、4)各スチールワイヤのたるみ量d(各スチールワイヤのなす曲線の最低高さと支持点の高さとの差)を計測して、得られた計測値dに基づき、前記式(1)より、各スチールワイヤの実長さLを算出した。その後、5)各スチールワイヤに挿入したプラスチックビーズをスプールの出線位置まで戻し、再度、スチールワイヤの引出し端部に近い一点で、スチールワイヤ同士をハンダで固定して、測定済みの鋼線長さ部分を切断した。   Next, 4) the amount of slack d of each steel wire (difference between the minimum height of the curve formed by each steel wire and the height of the support point) is measured, and based on the obtained measurement value d, the above equation (1) is used. The actual length L of each steel wire was calculated. After that, 5) Return the plastic beads inserted in each steel wire to the outgoing line position of the spool, and again fix the steel wires with solder at one point close to the end of the steel wire. The part was cut.

上記2)〜5)の手順を繰り返すことにより、たるみdの測定を10回行った。各計測値より、前記式(1)を用いて、各測定ごとの各スチールワイヤの実長さLを求め、総長さ100mあたりの各スチールワイヤの実長さLを算出した。その結果を、下記の表中に示す。   The slack d was measured 10 times by repeating the procedures 2) to 5). From the measured values, the actual length L of each steel wire for each measurement was obtained using the above equation (1), and the actual length L of each steel wire per total length of 100 m was calculated. The results are shown in the table below.

上記表中に示すように、6本のスチールワイヤのうち、最も長く巻かれていたものと最も短く巻かれていたものとの差は5.294mmであることが確かめられた。   As shown in the above table, it was confirmed that among the six steel wires, the difference between the longest wound wire and the shortest wound wire was 5.294 mm.

<実施例2>
上記実施例1で用いたのと同様の、線径φ0.225mm、単位重量0.312g/mのスチールワイヤを6本にて撚り合わせずに引き揃えたスチールワイヤ束を巻き取ったスプールについて、各スチールワイヤ長さの評価を行った。具体的には、スチールワイヤの引出し端末側に掛ける錘として、500gのものおよび200gのものを用いて、スチールワイヤ束の任意の箇所につき、それぞれたるみdの測定を10回行った。500gの重りを用いた場合の張力は、前記式により得られた値A(g)の約26.7倍である。得られた各計測値より、前記式(1)を用いて、各測定ごとの各スチールワイヤの実長さLを求め、総長さ100mあたりの各スチールワイヤの実長さLを算出した。錘の重量が500gの場合の結果を下記表2中に、錘の重量が250gの場合の結果を下記表3中に、それぞれ示す。
<Example 2>
About a spool wound up with a steel wire bundle similar to that used in Example 1 above, in which the steel wires having a wire diameter of 0.225 mm and a unit weight of 0.312 g / m are aligned without being twisted in six pieces, Each steel wire length was evaluated. Specifically, as the weight hung on the steel wire drawing terminal side, 500 g and 200 g weights were used, and the measurement of the slack d was performed 10 times for each arbitrary portion of the steel wire bundle. The tension when a 500 g weight is used is about 26.7 times the value A (g) obtained by the above formula. From the obtained measurement values, the actual length L of each steel wire for each measurement was obtained using the above equation (1), and the actual length L of each steel wire per total length of 100 m was calculated. The results when the weight is 500 g are shown in Table 2 below, and the results when the weight is 250 g are shown in Table 3 below.

上記表2,3中に示すように、6本のスチールワイヤのうち、最も長く巻かれていたものと最も短く巻かれていたものとの差は、錘の重量が500gの場合は5.867mmであり、錘の重量が250gの場合は22.189mmであった。このことから、計測時の荷重が大きすぎると、支持点間でスチールワイヤが張りすぎて、たるみ量の差が検出されにくくなり、測定精度が低下することが確認された。   As shown in Tables 2 and 3 above, among the six steel wires, the difference between the longest wound wire and the shortest wound wire is 5.867 mm when the weight of the weight is 500 g. And the weight was 22.189 mm when the weight was 250 g. From this, it was confirmed that if the load at the time of measurement is too large, the steel wire is stretched too much between the support points, and it becomes difficult to detect the difference in the amount of sag and the measurement accuracy is lowered.
