Description
本発明は、所定の幅と丈（長さ）を有する薄い面状体の捩回試験装置に関するものである。このような面状体としては、液晶ディスプレー、有機ＥＬ及び太陽電池パネル等があり、その幅は１ｍを超えるものもある。これら面状体は、製造、運搬、保管、施工に際して捩じり（捩回）を受けるが、このような捩回を受けるときは、概ね、引張力も圧縮力も受けない無張力の状態である。したがって、無張力で捩回試験をして耐久性を調べる必要がある。なお、ここでいう無張力とは、引張力も圧縮力も受けない状態のことをいう。 The present invention relates to a twist test apparatus for a thin planar body having a predetermined width and length (length). As such a planar body, there are a liquid crystal display, an organic EL, a solar battery panel, and the like, and there are some whose width exceeds 1 m. These planar bodies are subjected to torsion (twisting) during manufacturing, transportation, storage, and construction, and when such torsion is received, they are generally in a state of no tension that receives neither a tensile force nor a compressive force. Therefore, it is necessary to examine the durability by performing a torsion test without tension. Here, the term “no tension” refers to a state in which neither a tensile force nor a compressive force is applied.
本出願人は先にケーブル、ハーネス、コードといった線状体を無張力で曲げ（曲回）と捩回を同時に試験できる試験装置を下記特許文献１として提案している。ところが、面状体は上記したように相当広い幅を有しているから、これと同じやり方では捩回や曲回の試験ができないし、ましてや同時にはできない。 The present applicant has previously proposed Patent Document 1 as a test apparatus capable of simultaneously testing bending (bending) and twisting of a linear body such as a cable, a harness, and a cord without tension. However, since the planar body has a considerably wide width as described above, it is impossible to perform a twisting or bending test in the same manner, and moreover, it cannot be performed at the same time.
面状体の被試験体を直立させてその幅方向（左右方向）両端を固定クランプと揺動クランプで上下二点をクランプし（その間はフリーにする）、固定クランプはそのままで揺動クランプを揺動角θで揺動させると、被試験体は断面をとればどこも真っ直ぐであるが、被試験体全体はローラに螺旋形で巻き付いた形状、つまり、捩回した形態になっている。図５はその平面図であるが、捩回させたことでクランプ点間隔Ｒはθだけ傾き、クランプ点ａはａ´に移る。したがって、見かけ上は左右方向にＬだけ短くなるが、これは平面的に見た場合であり、実際は三次元的に短縮することになる（この場合でも、上下方向の中心線の長さは変わらない）。 Test the planar object upright and clamp both ends in the width direction (left and right) with a fixed clamp and a swing clamp (free between them), and leave the fixed clamp as it is. When the specimen is swung at a swing angle θ, the specimen under test is straight when taken in a cross section, but the whole specimen under test is a spiral wound around the roller, that is, a twisted form. FIG. 5 is a plan view thereof, and by twisting, the clamp point interval R is inclined by θ, and the clamp point a moves to a ′. Therefore, although it is apparently shortened by L in the left-right direction, this is a case where it is viewed in a plan view, and actually it is shortened three-dimensionally (even in this case, the length of the center line in the vertical direction is changed). Absent).
このため、揺動クランプを固定した垂直面内で揺動させて被試験体を捩回させると、被試験体はそれだけ長くなることになり、引張荷重を与えてしまう。これを吸収するには、短くなった分だけ揺動クランプと固定クランプの一方又は両方を移動できるようにしてその間隔を短縮すればよいのであるが、この場合も被試験体の捩回で移動側のクランプを引っ張ったのでは被試験体に引張荷重を与えてしまう。一方で、一旦捩回させたものを移動側のクランプを移動させた状態で捩じり戻すと、逆に圧縮荷重をかけることになる。よって、これらクランプ点間隔を別の力で短縮したり、伸長させれば、被試験体には引張や圧縮荷重を与えない、つまり、無張力で捩回できる。 For this reason, if the test object is twisted by swinging in a vertical plane to which the swing clamp is fixed, the test object becomes longer and a tensile load is applied. In order to absorb this, one or both of the oscillating clamp and fixed clamp can be moved by shortening the distance, and the distance between them can be shortened. If the side clamp is pulled, a tensile load is applied to the DUT. On the other hand, if the twisted one is twisted back with the moving clamp moved, a compressive load is applied. Therefore, if the distance between the clamp points is shortened or extended with another force, the test object is not subjected to tension or compression load, that is, can be twisted without tension.
本発明は、このクランプ点間隔の短縮と伸長を固定クランプ（揺動クランプでもよい）が移動できるようにすることと、その力を被試験体を揺動する駆動力や錘で作動する張力負担紐で負担させて被試験体に張力をかけない、つまり、無張力で捩回できるようにしたものである。 The present invention makes it possible to move the fixed clamp (which may be a rocking clamp) to shorten and extend the clamp point interval, and to apply the force to the driving force to swing the device under test and the tension load to operate with the weight. It is designed so that it can be twisted with no tension, that is, it can be twisted without tension.
このため、本発明は、請求項１に記載した、面状体をしている被試験体を真っ直ぐに立て、左右両端を揺動クランプと固定クランプとで上下二点でクランプしてその間をフリーにし、揺動クランプの中心を左右に揺動させて被試験体を捩回させる面状体の捩回試験装置であり、固定クランプを揺動クランプ側に移動できるようにしておくとともに、揺動クランプに連結される面板に二つのローラを回転可能に軸支して面板から張力負担紐を二つのローラの間を通して下延させて固定クランプに連結する一方、固定クランプからも張力負担紐を延出させてその端に錘を吊り下げておき、揺動クランプの揺動に基づく両クランプ点間の左右方向の短縮と伸長に対応して被試験体に負荷される引張力と圧縮力とを面板の揺動と錘による張力負担紐の両側への引っ張りで吸収したことを特徴とする面状体の捩回試験装置を提供するとともに、これにおいて、請求項２に記載した、被試験体に引張力と圧縮力を発生させないように張力負担紐と錘の引っ張りによる固定クランプの移動を同期させたさせた手段を提供する。 Therefore, in the present invention, the test object having a planar shape according to claim 1 is set up straight, and both left and right ends are clamped at two upper and lower points by a swing clamp and a fixed clamp, and the space between them is free. This is a torsional testing device for a planar body that swings the center of the swinging clamp from side to side and twists the device under test. The fixed clamp can be moved to the swinging clamp side and swings. Two rollers are rotatably supported on the face plate connected to the clamp, and the tension load string is extended from the face plate through the space between the two rollers to be connected to the fixed clamp, while the tension load string is also extended from the fixed clamp. A weight is hung from the end of the swing clamp, and the tensile force and compressive force applied to the DUT in response to the shortening and extension in the horizontal direction between the two clamp points based on the swing of the swing clamp. The swing of the face plate and the tension strap A torsional testing apparatus for a planar body characterized by absorption by pulling to the side, wherein the tension is set so as not to generate a tensile force and a compressive force in the test object according to claim 2. Provided is a means for synchronizing the movement of a fixed clamp by pulling a load string and a weight.

揺動力や錘で強制的に引っ張って短縮と伸長をさせることで封殺でき、結果的に、被試験体を無張力で捩回させることができる。これにおいて、請求項２の手段によれば、厳密な意味での無張力で捩回できる。
According to the invention of claim 1, by swinging the peristaltic clamp, the tensile force or the compressive force based on the shortening and extension of the clamp point interval due to the torsion and return (return) of the DUT can be changed. It can be sealed by forcibly pulling to shorten and elongate, and as a result, the device under test can be twisted without tension. In this case, according to the means of claim 2, it can be twisted without tension in a strict sense.
以下、本発明の実施の形態を図面を参照して説明する。図１は本発明の第１例を示す捩回試験装置の側面図、図２は図１のＡ−Ａ断面図であるが、この試験装置は、装置の基礎となるベッド１と、このベッド１上をスライドできるベース２と、ベース２の上に直立させられる支柱３に取り付けられる固定クランプ４と、固定クランプ４に対向して設けられる揺動クランプ５を揺動するためにその中心に設けられて強制的に揺動駆動される揺動軸６とからなる。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a torsional test apparatus showing a first example of the present invention, and FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1. This test apparatus includes a bed 1 serving as the basis of the apparatus and the bed. 1. A base 2 that can slide on the base 1, a fixed clamp 4 that is attached to a support column 3 that stands upright on the base 2, and a swing clamp 5 that is provided to face the fixed clamp 4 are provided at the center for swinging. And a swing shaft 6 that is forcibly driven to swing.
さらに、揺動軸６に連結される面板７と、揺動クランプ５と面板７との間に回転可能に軸支される二つのローラ８と、面板７に取り付けられたピン９に上端が連結されてローラ８の間を通って垂れ下がり、プーリ等１０で水平に方向転換されてベース２に連結されるとともに、ベース２から延出して同じくプーリ等１０で下方に方向転換されて下端に錘１１が吊り下げられる張力負担紐１２等を有する。 Further, the upper end is connected to a face plate 7 connected to the swing shaft 6, two rollers 8 rotatably supported between the swing clamp 5 and the face plate 7, and a pin 9 attached to the face plate 7. Then, it hangs down between the rollers 8 and is horizontally changed by a pulley 10 or the like and connected to the base 2, and extends from the base 2 and is also turned downward by the pulley 10 and the weight 11 at the lower end. Has a tension strap 12 and the like on which the strap is suspended.
図３は固定クランプ４と可動クランプ５による被試験体１３のクランプ点の状態の一例を示す断面図であるが、それぞれ相手側に開口したＵ字体の筐体４ａ、５ａを形成し、この筐体４ａ、５ａの中に被試験体１３を挿入し、筐体４ａ、５ａの両面からボルト等のクランプ具１４で締め付けてクランプするものが考えられる。 FIG. 3 is a cross-sectional view showing an example of the state of the clamp point of the device under test 13 by the fixed clamp 4 and the movable clamp 5. U-shaped housings 4 a and 5 a that are opened on the other side are formed, respectively. It can be considered that the device under test 13 is inserted into the bodies 4a and 5a and clamped by clamping with clamps 14 such as bolts from both sides of the housings 4a and 5a.
この場合、クランプ具１４の先端に被試験体１３を挟圧するカップ１５を設け、カップ１５とクランプ具１４を回転自在にしておく。被試験体１３を捩回させた（左右方向に短縮する）場合でも、被試験体１３の上下中央部分の長さは変わらないから、この部分は相対的に伸長できなければならない。したがって、被試験体１３がクランプ具１４に対して自由に回転できれば、この伸長を阻害しない。この意味で、筐体４ａ、５ａの深さはこれを許容するものである必要がある。 In this case, a cup 15 for clamping the device under test 13 is provided at the tip of the clamp tool 14 so that the cup 15 and the clamp tool 14 are rotatable. Even when the device under test 13 is twisted (shortened in the left-right direction), the length of the upper and lower central portions of the device under test 13 does not change, so this portion must be able to be relatively extended. Therefore, if the DUT 13 can freely rotate with respect to the clamp tool 14, this extension is not hindered. In this sense, the depth of the casings 4a and 5a needs to allow this.
次に、被試験体１３の捩回試験について捩回を例にとって説明すると、固定クランプ４と可動クランプ５に被試験体１３の左右両端の上下二点をクランプ具１４でクランプし、揺動軸６を一定の揺動角と速度とで揺動回転させる。すると、揺動クランプ５は揺動し、これに伴って被試験体１３は捩回し、見かけ上は左右方向に短縮したようになるのは上述したとおりである。 Next, the torsion test of the device under test 13 will be described by taking an example of torsion. The upper and lower two points on both the left and right sides of the device under test 13 are clamped to the fixed clamp 4 and the movable clamp 5 by the clamp tool 14, and the swing shaft 6 is oscillated and rotated at a constant oscillating angle and speed. As a result, the swing clamp 5 swings, and the device under test 13 is twisted along with this, as described above.
このままであると、固定クランプ４が移動できるとしても、被試験体１３で引っ張ることになり、被試験体１３に引張荷重がかかるのも上述したとおりである。そこで、この移動を張力負担紐（以下、紐）１２で行うのである。つまり、面板７の揺動で紐１２を引っ張り、固定クランプ４を引き寄せるのであり（もちろん、錘１１も一緒に）、こうすると、被試験体１３には張力はかからない。このようにして、捩回の間中、被試験体１３は無張力に保たれる。すなわち、被試験体１３の捩回は無張力で行われるのである。 If this is the case, even if the fixed clamp 4 can be moved, it will be pulled by the device under test 13, and the tensile load is applied to the device under test 13 as described above. Therefore, this movement is performed by a tension bearing string (hereinafter, string) 12. That is, the string 12 is pulled by the swing of the face plate 7 and the fixed clamp 4 is drawn (of course, together with the weight 11), and in this way, no tension is applied to the device under test 13. In this way, the device under test 13 is kept in tension during the twisting. That is, the to-be-tested body 13 is twisted without tension.
これを可能にするには、被試験体１３の短縮量と紐１２の引張量が同じである必要がある。揺動クランプ５、つまり、面板７が揺動すると、紐１２を通すローラ８も傾き、このとき、紐１２はローラ８に巻き付いてピン９とプーリ１０間が長くなり、上方に引っ張られ、固定クランプ４を引き寄せる（揺動クランプ５側或いは両方を移動できるようにしてもよい）。被試験体３の短縮量と紐１２の引張量を一致させるには、ローラ８の径を適宜に調整したり、ローラ８のセットを面板７に対して上下に調整することで可能になる（ただし、揺動は左右同じであるから、ローラ８の軸芯の中点の移動はこの点を通る垂直線上を移動させる）。 In order to make this possible, the amount of shortening of the DUT 13 and the amount of tension of the string 12 need to be the same. When the swing clamp 5, that is, the face plate 7 swings, the roller 8 through which the string 12 passes is also tilted. At this time, the string 12 is wound around the roller 8, and the distance between the pin 9 and the pulley 10 becomes long and is pulled upward and fixed. The clamp 4 is pulled close (the swing clamp 5 side or both may be moved). In order to make the shortening amount of the DUT 3 and the tension amount of the string 12 coincide, it is possible to adjust the diameter of the roller 8 appropriately or adjust the set of the roller 8 up and down with respect to the face plate 7 ( However, since the swing is the same on the left and right, the movement of the center point of the axis of the roller 8 moves on the vertical line passing through this point).
このとき、被試験体３に負荷される引張荷重は揺動角の変化と同じにはなっていないことがあるが、それでも、被試験体３を捩回させただけ、ローラ８も揺動して紐１２を引っ張り上げる。したがって、捩回による短縮と紐１２の引張とは同期して作動しており、捩回の途中で被試験体３に引張荷重はかけていないといえる。なお、より厳密に同期させるには、捩回の角度（揺動角）による被試験体３の引張荷重を予め求めておくとともに、揺動角の変化に基づいて紐１２の引張量を調整すればよい。 At this time, the tensile load applied to the device under test 3 may not be the same as the change in the rocking angle, but the roller 8 still rocks just by twisting the device under test 3. Then pull the string 12 up. Accordingly, it can be said that the shortening due to the twisting and the tension of the string 12 are operated in synchronism, and no tensile load is applied to the DUT 3 during the twisting. In order to synchronize more precisely, the tensile load of the DUT 3 according to the twist angle (swing angle) is obtained in advance, and the tension amount of the string 12 is adjusted based on the change in the swing angle. That's fine.
具体的には、ローラ８のセットを面板７に対してサーボモータ等（駆動源のこと、なお、電動シリンダや油圧シリンダでもよい）で上下又は左右に移動できるようにしておき（ピン９とプーリ１０との間の紐１２が長いほど大きな引張量を出せる）、揺動角をセンサーで検知して駆動源に同期させるように出力することである。この場合、駆動源の揺動角と速度とは被試験体３に負荷される圧縮荷重に対応させるのはもちろんである。これによると、大きな揺動角度であっても、捩回の間中、被試験体３には引張荷重はかからず、完全な無張力で捩回試験ができる。 Specifically, the roller 8 set can be moved up and down or left and right with respect to the face plate 7 by a servo motor or the like (drive source, which may be an electric cylinder or hydraulic cylinder) (pin 9 and pulley). The longer the string 12 between 10 is, the larger the amount of tension can be obtained), and the swing angle is detected by a sensor and output so as to be synchronized with the drive source. In this case, of course, the swing angle and speed of the drive source correspond to the compressive load applied to the DUT 3. According to this, even when the rocking angle is large, the to-be-tested body 3 is not subjected to a tensile load during the twisting, and the torsion test can be performed with complete no tension.
一方、揺動角の減少による固定クランプ４の元の位置への復帰も同様であり、この場合は錘１１で紐１２を引っ張る。揺動角が小さくなり、紐１２の引張力が緩めば、錘１１が固定クランプ４を引っ張って元に復帰させる。この点で、錘１１はある程度重いものを使用しておく方が反応が早い。なお、固定クランプ４の復帰も被試験体３の伸長に厳密に対応させておくことができる。具体的には、錘１１自体或いは錘１１に加えて何らかの駆動源を用いて固定クランプ4 を戻すのであり、その速度と量を被試験体３にかかる圧縮荷重と同期させるのは上記と同じである。 On the other hand, the return of the fixed clamp 4 to the original position by the decrease of the swing angle is the same. In this case, the string 12 is pulled by the weight 11. When the swing angle is reduced and the tension of the string 12 is loosened, the weight 11 pulls the fixed clamp 4 to return to the original state. In this respect, the reaction is faster when the weight 11 is somewhat heavy. Note that the return of the fixed clamp 4 can also correspond exactly to the extension of the DUT 3. Specifically, the fixed clamp 4 is returned using the weight 11 itself or the weight 11 in addition to the weight 11, and the speed and amount thereof are synchronized with the compressive load applied to the object 3 to be tested in the same manner as described above. is there.
図４は第２例の側面図であるが、本例のものは、支柱３をベッド１に不動にして取り付け、これに直接固定クランプ４を取り付ける。また、揺動クランプ５は揺動軸６に直接取り付け、これら固定クランプ４と揺動クランプ５とで被試験体１３の左右両端をクランプする。 FIG. 4 is a side view of the second example. In this example, the column 3 is fixedly attached to the bed 1 and the fixed clamp 4 is directly attached thereto. The swing clamp 5 is directly attached to the swing shaft 6, and the right and left ends of the device under test 13 are clamped by the fixed clamp 4 and the swing clamp 5.
本例では、固定クランプ４及び揺動クランプ５として、リンク１６をピン１７で連結したチェンのような彎曲可能なリンク状クランプ１８としたものであり、これにより、リンク状クランプ１８は引っ張られると彎曲できるものになる。ただし、彎曲は被試験体１３側にのみできるようにしておき、直立を超えて反被試験体１３側には彎曲できないようにしておくのが好ましい。元に戻るときの反動で被試験体１３に引張荷重をかけないためである。図示は省略するが、 リンク１６の背等にストッパ片等をつけておけばよい。こうすると、クランプ具１４は被試験体１３の全高に亘ってクランプしてもよい。 In this example, the fixed clamp 4 and the oscillating clamp 5 are formed as a link-shaped clamp 18 that can be bent like a chain in which the link 16 is connected by a pin 17, and thus the link-shaped clamp 18 is pulled. It can be folded. However, it is preferable to bend only on the DUT 13 side and not to be bent on the side of the DUT 13 beyond the upright. This is because a tensile load is not applied to the DUT 13 due to the reaction when returning to the original state. Although illustration is omitted, a stopper piece or the like may be attached to the back of the link 16 or the like. In this way, the clamp 14 may be clamped over the entire height of the device under test 13.
以上の状態で揺動軸６を揺動させて被試験体１３を捩回させる。この場合も、被試験体１３の上下両端を最大とする左右方向の短縮が起こるが、これをリンク状クランプ１８が彎曲して吸収する。なお、被試験体１３に引張力が働いたときにリンク状クランプ１９が彎曲するので、それまでに多少の引張力は働くが、彎曲させることでこれをほとんど無視できる程度のものにできる（無張力といってもよい）。なお、リンク状クランプ１８は固定クランプ４側、揺動クランプ５側の一方だけでもよい。 In the above state, the rocking shaft 6 is rocked to twist the device under test 13. In this case as well, the horizontal shortening that maximizes the upper and lower ends of the DUT 13 occurs, but the link clamp 18 is bent and absorbed. The link clamp 19 bends when a tensile force is applied to the device under test 13, so that some tensile force works until then, but it can be made almost negligible by bending (nothing). May be called tension). The link clamp 18 may be only one of the fixed clamp 4 side and the swing clamp 5 side.
また、揺動クランプ５が中立近くなると、逆に伸長が必要になるが、このときも、リンク状クランプ１９が彎曲から直立になって（ストッパ機構があるものはそれ以上は彎曲しない）圧縮荷重が生ずるのを防ぐ。この意味で、支柱３とリンク状クランプ１８の間に彎曲になったものを引き戻すスプリング（図示省略）を設けておくのが適する。本例のものは、構造が極めて簡単になり、製造コストを大幅に低減できる利点がある。 In addition, when the swinging clamp 5 becomes nearly neutral, it is necessary to extend, but also at this time, the link-like clamp 19 becomes upright from the bent (the one with the stopper mechanism does not bend further). To prevent the occurrence of In this sense, it is suitable to provide a spring (not shown) for pulling back the bent one between the support column 3 and the link clamp 18. This example has the advantage that the structure is extremely simple and the manufacturing cost can be greatly reduced.
