【考案の詳細な説明】
Ａ 産業上の利用分野
本考案は標線間伸びを非接触で測定する際に用
いる標線ターゲツトを備えた試験片に関する。[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a test piece equipped with a marked line target used for non-contact measurement of elongation between marked lines.
Ｂ 従来の技術
たとえばプラスチツクや樹脂材から成る試験片
の強伸度特性を測定する際、従来は、塗料で直接

ーゲツトとしたり、表面に標線が描かれた試験片
とは別体の標線ターゲツトを用意し、その裏面全
域に接着剤を塗布して試験片に貼着していた。B. Conventional technology For example, when measuring the strength and elongation characteristics of a test piece made of plastic or resin, conventional techniques include directly marking it with paint to form a gauge line and using it as a target for a non-contact sensor, or marking the surface with a gauge line. A marked line target separate from the test piece on which was drawn was prepared, adhesive was applied to the entire back surface of the target, and the target was attached to the test piece.
Ｃ 考案が解決しようとする問題点
前者の塗料による場合、試験片の材質によつて
科学変化を生じ強伸度特性に影響を与えたり、試
験片の変位により試験片そのものが変色して塗料
との明度差が小さくなり、センサによる追従がで
きないことがある。C. Problems that the invention aims to solve When using the former type of paint, chemical changes may occur depending on the material of the test piece, affecting the strength and elongation properties, and the displacement of the test piece may cause the test piece itself to discolor, resulting in a difference between the paint and the paint. The difference in brightness may become small and the sensor may not be able to track it.
一方、後者の接着剤による場合、フイルム状の
薄い試験片では、接着剤が試験片の変位を拘束し
て正確な強伸度特性が測定できなかつたり、ター
ゲツトが脱落することがある。 On the other hand, when using the latter adhesive, in the case of a thin film-like test piece, the adhesive may restrict the displacement of the test piece, making it impossible to accurately measure strength and elongation properties, or the target may fall off.
本考案の目的は、このような従来の問題点を解
決した標線ターゲツトを備えた試験片を提供する
ことにある。 An object of the present invention is to provide a test piece equipped with a marked line target that solves these conventional problems.
Ｄ 問題点を解決するための手段
標線が付されたターゲツト本体をその標線が試
験片の標線位置と一致するよう、試験片の標線に
塗布した接着剤によつて試験片に貼着する。D. Measures to solve the problem: Attach the target body with a marked line to the test piece using adhesive applied to the marked line of the test piece so that the marked line matches the position of the marked line on the test piece. wear it.
Ｅ 作用
試験片の伸びは接着剤に拘束されず、標線間の
伸びを非接触式センサで正確に測定でき精度良い
強伸度特性が得られる。E Effect The elongation of the test piece is not restricted by the adhesive, and the elongation between the gauge lines can be accurately measured using a non-contact sensor, allowing highly accurate strength and elongation characteristics to be obtained.
Ｆ 実施例
第１図〜第３図により本考案の一実施例を説明
する。F. Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 3.
たとえばプラスチツクや樹脂材からなる試験片
TPを上方つかみ具２１と下方つかみ具２２で把
持し、その試験片TPの初期標線位置に負荷方向
と直交して接着剤１２を線状に塗布する。試験片
TPとは別体の一対のターゲツト本体１０の各表
面には１本の標線１１が形成され、各標線１１が
線状の接着剤１２に合致するよう各ターゲツト本
体１０を試験片TPに貼着する。これにより試験
片TPに所定距離だけ離間した一対の標線１１が
設けられる。 For example, specimens made of plastic or resin materials.
The TP is held by the upper grip 21 and the lower grip 22, and the adhesive 12 is linearly applied to the initial marked line position of the test piece TP perpendicular to the load direction. Test pieces
One marked line 11 is formed on each surface of a pair of target bodies 10 separate from the TP, and each target body 10 is attached to the test piece TP so that each marked line 11 matches the linear adhesive 12. Paste. As a result, a pair of marked lines 11 are provided on the test piece TP, separated by a predetermined distance.
図示しない非接触センサにより両標線１１を検
出する。試験片TPに引つ張り負荷が働くと試験
片TPが伸び非接触センサが標線１１の位置変化
を検出して伸びが測定される。このとき、試験片
TPは接着剤１２に何ら拘束されずに伸びるから、
精度の良い強伸度特性が得られる。 Both marked lines 11 are detected by a non-contact sensor (not shown). When a tensile load is applied to the test piece TP, the test piece TP stretches, and the non-contact sensor detects a change in the position of the marked line 11 to measure the elongation. At this time, the test piece
Since TP stretches without being restricted by the adhesive 12,
Accurate strength and elongation characteristics can be obtained.
なお、ターゲツト本体１０の裏面に標線１１と
略同一方向で略同一位置に線状の接着剤層を形成
し貼着しても良い。また、本考案はプラスチツク
や樹脂材以外の金属材から成る試験片にも実施で
きる。 Note that a linear adhesive layer may be formed on the back surface of the target body 10 in substantially the same direction and at substantially the same position as the marked line 11 and adhered thereto. Furthermore, the present invention can be applied to test specimens made of metal materials other than plastic and resin materials.
Ｇ 考案の効果
本考案は以上のように構成したから、ターゲツ
ト本体接着剤により試験片の伸びが拘束されず精
度の良い伸び測定ができる。G. Effects of the invention Since the present invention is configured as described above, the elongation of the test piece is not restricted by the adhesive of the target body, allowing highly accurate elongation measurement.
