【発明の属する技術分野】
本発明は、直立した外筒を備える容器の外筒内壁に沿う環状空間内にペイル巻きにより積層した状態で収納された溶接用ワイヤの上部に載置して、この溶接用ワイヤを順次引き出す際のワイヤ同士の絡み合いを防いで、溶接用ワイヤを円滑に順次引き出すことができるようにした溶接用ワイヤの押さえ板に関する。
【0002】
【従来の技術】
容器内にペイル巻きして積層した状態で収納された溶接用ワイヤを、跳ね上がり及び飛び出しはもとより、躍りや絡みなどをも有効に阻止しながら連続した引出しを可能とするためのこの種の押さえ板に関する典型的な先行技術が実公平 3− 13489号公報に挙げられるように公知である。
【0003】
上記先行技術によれば、図6に示されるように押さえ板13は、巻回積層したワイヤ上に載置され、容器の外筒11(図5参照)の内壁に沿って配設される環状の縦壁部14と、この縦壁部14の下端より内向きに延びて容器の内筒(図示せず)の外壁に弾性的に当接し且つこの当接の反発力により縦壁部14を外筒11の内壁に当接させる多数の弾性内向片15とにより形成される。
【0004】
このような押さえ板において、弾性内向片15は略二等辺三角形の先細り状を成しており、容器内のペイル巻き溶接用ワイヤ上に円環状に丸めて載置すると、多数の弾性内向片15は、先端部の頂角部分15Bを容器の中心に向けた筒径方向に整列して溶接用ワイヤ上に配設されることになり、引き出される溶接用ワイヤの跳ね上がりを防止するように作用する。
【0005】
この押さえ板を、外筒だけで内筒を有しないペイルパックと通称される容器に適用した場合、頂角部分は当接する部材がなくて自由端となっているのと、溶接用ワイヤに作用する弾性内向片15の押圧力を適正な値に保持するのが容易なことでないのとによって、押さえ板が設けられているにもかかわらずペイル巻きの内部空間にワイヤが2〜3ループ纏まって引き出され、絡みやもつれを生じる問題があった。
【0006】
【発明が解決しようとする課題】
このような問題を解決する手段として前記先行技術にも開示されるように、押さえ板とは別体の環状を成すワイヤ押さえ用おもりを多数の弾性内向片15の上面に載置させて、引き出されるワイヤが作用する押し上げ力によって弾性内向片15の前記頂角部分が必要以上に湾曲変形するのを防止するようにしている。しかしながら、ワイヤ押さえ用おもりは、軽いとこの変形防止作用が十分に発揮されないし、反対に重いとワイヤの引出しに大きな力が必要となって円滑な引出しが行われない等の問題があって、ワイヤ押さえ用おもりの設計に細心の注意を払う必要があって面倒である。
【0007】
一方、このようなワイヤ押さえ用おもりを使用しないで、押さえ板だけで所期の円滑な引出しを可能とするためには、その材質、重量などの素材面について種々の検討を重ねることによりある程度解決が図れるが、それ以上に形状、大きさ、数などの前記弾性内向片15についての形態がワイヤの躍り、絡みや飛び出し等の異常引出しを有効に阻止する上に多大の影響を及ぼすものであることが判ってはいるが、現在のところこれを技術的に解明するには至っていないのが実状である。
【0008】
本発明は、このような問題点の解消を図るために成されたものであり、したがって、本発明の主たる目的は、ペイル巻き溶接用ワイヤの引出しの際にワイヤの跳ね上がり、飛び出しの発生を未然に防ぎ、また、ワイヤ同士の絡み合いが生じるのも確実に防止して、円滑なワイヤ引出しを行い得るようにした溶接用ワイヤの押さえ板を提供することにある。
【0009】
本発明の他の目的は、従来は必要部材とされていたワイヤ押さえ用おもりを使用しないで押さえ板だけによってワイヤの跳ね上がり、飛び出しを確実に防止することを可能とし、安定したワイヤ引出しを実現し得る溶接用ワイヤの押さえ板を提供することにある。
【0010】
本発明のさらに他の目的は、押さえ板における特に弾性内向片の形態に関して特定の条件を見出してなることによって、弾性内向片の曲がり強度を高めてワイヤを押さえ付ける力を適正に保持することができ、もって押さえ板のみの使用で絡みなどの不正常な状態の発生を防いで円滑なワイヤ送給の実現を図ることにある。
【0011】
【課題を解決するための手段】
上記目的を達成するために、本発明のうち請求項1記載の発明は、ペイル巻き溶接用ワイヤが収納される容器の外筒周長に比して長い帯板状を成し該外筒の内壁に当接される縦壁部と、この縦壁部の下端から所要間隔を存して内向きに折れ曲がって延び、かつ、前記縦壁部の下端に連なる底辺部分から先端部の頂角部分に向け先細り状を成して、前記容器に収納した前記ペイル巻き溶接用ワイヤ上に載置される複数の弾性内向片とから成る溶接用ワイヤの押さえ板において、弾性内向片を、底辺部分の中心点からこの弾性内向片の面内に直角方向に延びる基準線に対して頂角部分が溶接用ワイヤの引出し方向にずれた略不等辺三角形状に形成してなることを特徴とする。
【0012】
このように形成すると、基準線に対して頂角部分のずれ量が無い従来の押さえ板に比べて、引き出されるワイヤをより多くの弾性内向片で押さえることが可能となり、スムーズなワイヤ送給ができるとともに、収納容器上ワイヤ引出し点とペイル巻き積層ワイヤの引出し開始部の間のワイヤたるみ量を減らせてキンクやもつれの発生を未然に防止できる。
【0013】
基準線に対する頂角部分のずれ量は大きい程引き出されるワイヤを押さえる弾性内向片は増える傾向になるが、他方、ワイヤを押さえ付ける力が減少して、ワイヤのもつれ、絡みの原因になる。従って、本発明のうち請求項2〜5に記載の発明の構成のように、ずらし量lと前記底辺部分の辺長Lとの間に、0.4×L≦l≦Lの関係式が満たされること、ワイヤの引出し方向の上手側に位置する長い方の斜辺と基準線との交差角度θを13°〜50°、好ましくは20°〜40°とすること、弾性内向片の長さHとペイル巻き溶接用ワイヤの積層幅Wとの間に、W≦H≦1.8×Wの関係式が満たされること、の特有の各条件を設定することによって、よりスムーズで、かつ、安定性が高いワイヤ送給を行わせることが可能である。
【0014】
【発明の実施の形態】
以下、本発明の実施の形態の一例を、添付図面を参照しながら具体的に説明する。各図面において、図1はペイル巻き溶接用ワイヤが収納される容器の断面図、図2は押さえ板の側面図、図3は同じく平面図、図4は図1に対応する平面図である。
【0015】
図1において、1は外筒、例えば有底直立円筒の外筒を備える容器であって、該容器1の内部空間に捩り入りの溶接用ワイヤがペイル巻状で積層して収納されている。2はこのペイル巻き溶接用ワイヤを示している。ペイル巻き溶接用ワイヤ(以降、ワイヤと略称する)2の上端部には押さえ板3が載置され、ワイヤ引出しの際のワイヤ跳ね上がりを防止するようになっている。
【0016】
押さえ板3は、好ましくは弾性材料から成り、一つの縦壁部4と複数の弾性内向片5とを備える所望の形状に一体で成形される。縦壁部4は、容器1の外筒周長に比して若干長だけ長い帯板状を成していて、該外筒の内壁に面接触により当接される部分である。複数の弾性内向片5は、縦壁部4の下端から所要間隔を存して内向きに直角方向に折れ曲がって延びて、縦壁部4の下端に連なる底辺部分5Aから先端部の先が丸まった頂角部分5Bに向けて先細り状を成していて、容器1内の前記ワイヤ2上面に沿わせて載置される部分である。
【0017】
このような構造になる押さえ板3において、前記弾性内向片5は略不等辺三角形状を成しており、底辺部分5Aの中心点から該内向片5の面内に底辺と直角方向に延ばした基準線7に対して、頂角部分5Bをワイヤ2の引出し方向にずらした形状となっており、底辺部分5Aと頂角部分5Bの間に亘る二つの斜辺は、ワイヤ2の引出し方向を基準として上手側斜辺6Aが下手側斜辺6Bよりも長くなっている。
【0018】
上記押さえ板3の材質としては、ポリエステル樹脂、ポリプロピレン樹脂、塩化ビニール樹脂等の適度な弾性を有し、繰り返し曲げに対しても十分な強度を持つ材料が好適である。また、比較的寒冷な場所で使用される機会も多いことから、低温使用条件下における強度を十分に備えた材料を使用することも好ましい手段である。
【0019】
このような押さえ板3を容器1内のワイヤ2上面に円環状に丸めて載置することにより、ワイヤ2は、ペイル巻きの上端から押さえ板3の弾性内向片5の周縁に接触移動しながら回転して上方に引き出される。このとき、ワイヤ2に接する弾性内向片5が多少の変形を受け、これによって、対応する位置の縦壁部4が外筒の内壁により強く当接されて、ワイヤ2が必要以上に長く引き出されるのを防ぐと共に、押さえ板3の降下を良好に行わせ、かくして、ワイヤ2の引出しを円滑、かつ、絡みやもつれがない状態で安定的に行わせることができる。
【0020】
ところで、押さえ板3における弾性内向片5の形状は、ワイヤ2の絡み、もつれに対して少なからぬ影響を与えるものであり、頂角部分5Bの基準線7に対するずらし量lが0である従来品と比べて、ずらし量lを適当に設定した本発明品の方がスムーズなワイヤ送給を行わせる上で有効であることが種々の実験を行ったことから判明した。前記ずらし量lと弾性内向片5曲がり強度・ワイヤ送給のスムーズさを調べた実験結果は、後記の〔表1〕に示される通りである。
【0021】
〔表1〕から明らかなように、ずらし比(ずらし量lと底辺部分5Aの辺長Lの%比)が167%のように大きすぎると、ワイヤを押さえ付ける力が減少して絡みやもつれの原因となり、弾性内向片5曲がり強度・ワイヤ送給のスムーズさの点については、ずらし比(上手側斜辺6Aと基準線7との交差角度θ)が、ずらし比:17%(交差角度θ:16°)からずらし比:150%(交差角度θ:46°)までの範囲で効果があり、更にずらし比:67%(交差角度θ:30°)前後で最も効果が顕著であることが判った。
【0022】

【0023】
【実施例】
以下、本発明の実施例について添付図面を参照しながら説明する。
本発明に係る押さえ板3は、所定長さの有端帯状に形成されており、無端環状のものに比べて容器1の外筒の径が多少変化しても使用可能であり、また、保管、運搬に際してもスペースを取らない利点がある。そして、容器1へのセット時には両端部分を重ね合わせることによって円環状で使用するものである。この点については、円環状であると弾性内向片5が上下方向に曲がる等の変形が生じ、ワイヤ送給作用が不安定になるのに対して、有端帯状ではこれを防止することが可能である。また、従来、容器1へのセット時に端部を結合していた手間を省くことができる。なお、弾性内向片5が上下方向に曲がるのは、底辺部分5Aの縦壁部4への取付け部が直線であるために、円環にした状態で長時間放置しておくと、取付け部での反り力によって弾性内向片5が曲がり易くなるからである。
【0024】
本発明に係る押さえ板3の具体的態様については、例えば、縦壁部4の高さを55mmとしたときに、弾性内向片5の底辺部分5Aの辺長Lを60mmとし、また、円環状で使用するときの両端部分における重ね代を辺長Lの2倍の120mmとして、縦壁部4の全長を容器1の外筒周長と120mmの和に略相当する長さに選定するのが適当である。
【0025】
弾性内向片5の長さH(底辺部分5Aからの頂角部分5Bの高さ)とワイヤ2の積層幅W(ペイル巻きの外径φo と内径φi の差の1/2)は、W≦H≦1.8×Wの関係式を満たすことが望ましく、H=1.25Wが最適とされる条件である。また、一般的に弾性内向片5の長さHが短すぎるとワイヤ2が弾性内向片5の上に乗り越えてしまい、キンクやもつれの原因になることがあり、一方、Hが長すぎるとワイヤ2と弾性内向片5の当たりが強くなり、弾性内向片5破損の原因となる。従って、上述の式を満足する範囲内が良く、弾性内向片5の長さHがワイヤ2の積層幅Wの25%増付近が最適であることが判っている。
【0026】
円環状に載置した押さえ板3における弾性内向片5の前記交差角度θとワイヤ2への押さえとの関係について、本発明に係るワイヤ2が収納される容器1の態様を平面図で示す図4及び従来の押さえ板を用いた場合の図4に対応する平面図である図5を参照して説明する。通常、引き出されるワイヤ2は、引き出される位置イに対して環約180°手前側位置ロで、一旦、容器1の内壁に押し付けられてその後引き出される。また、押さえ板3も同様に位置イの約半環手前の位置ロに略相当する位置でワイヤ2の引き出される力の反力によって容器1の内壁に押し付けられる。
【0027】
ところが、押さえ板3が容器1の内壁に押え付けられる位置は、交差角度θによって異なることが判った。即ち、前記〔表1〕に示すように実験の結果から明らかであるが16°〜46°の間が適当であって、このときの押さえ板3が容器1の内壁に押え付けられる位置は、従来の押さえ板13の場合のその位置に比べてワイヤ2が引き出される位置イより離れるようになり、これによって、押さえ板3の押さえがスムーズになってワイヤ送給の安定性が向上するのである。
【0028】
本発明は上述の構成としたことによって、ワイヤの円滑な引出しを押さえ板3だけの使用で確実に行わせることが可能であるが、勿論、ワイヤ押さえ用おもりの併用を妨げるものではない。また、縦壁部4を弾性内向片5に比して肉厚に形成して自重を持たせることにより、ワイヤ2の降下に対して押さえ板3を追随性良く降下させることも可能であって、このような変形もまた本発明の範囲に包含されるものである。
【0029】
【発明の効果】
本発明は以上述べた構成を有し、作用を成すものであって、容器にペイル巻・積層して収納された溶接用ワイヤの引出しに優れた効果を奏し、絡みやもつれを発生させることなく円滑に溶接用ワイヤを順次引き出して溶接部に安定送給させることが可能である。

BACKGROUND OF THE INVENTION
The present invention is to place a welding wire on top of a welding wire housed in a state of being stacked by pail winding in an annular space along an inner wall of an outer cylinder of a container having an upright outer cylinder, and sequentially pulling out the welding wire. The present invention relates to a presser plate for a welding wire that prevents the wires from being entangled and enables the welding wire to be pulled out smoothly and sequentially.
[0002]
[Prior art]
This type of presser plate that enables continuous pulling of the welding wire stored in a piled state in a container while being piled up while effectively preventing jumping and jumping, as well as jumping and entanglement. A typical prior art relating to this is known as disclosed in Japanese Utility Model Publication No. 3-13489.
[0003]
According to the above prior art, as shown in FIG. 6, the pressing plate 13 is placed on the wound and laminated wire and is arranged along the inner wall of the outer cylinder 11 (see FIG. 5) of the container. The vertical wall portion 14 extends inward from the lower end of the vertical wall portion 14 and elastically contacts the outer wall of the inner cylinder (not shown) of the container. It is formed by a large number of elastic inwardly facing pieces 15 which are brought into contact with the inner wall of the outer cylinder 11.
[0004]
In such a presser plate, the elastic inward pieces 15 have a substantially isosceles triangular taper shape. When the elastic inward pieces 15 are placed on a pail-winding wire in a container while being rolled into an annular shape, a large number of elastic inward pieces 15 are provided. Is arranged on the welding wire so that the apex angle portion 15B of the tip portion is aligned in the cylinder radial direction toward the center of the container, and acts to prevent jumping of the drawn welding wire. .
[0005]
When this presser plate is applied to a container commonly referred to as a pail pack that has only an outer cylinder and does not have an inner cylinder, the apex portion has no abutting member and has a free end, which acts on the welding wire. Since it is not easy to keep the pressing force of the elastic inwardly facing piece 15 at an appropriate value, two to three loops of wires are bundled in the internal space of the pail winding despite the pressing plate being provided. There was a problem of being drawn and causing entanglement and tangles.
[0006]
[Problems to be solved by the invention]
As disclosed in the prior art as means for solving such a problem, a wire pressing weight, which is a ring separate from the pressing plate, is placed on the upper surface of a large number of elastic inwardly facing pieces 15 and pulled out. This prevents the apex angle portion of the elastic inwardly facing piece 15 from being bent and deformed more than necessary due to the pushing-up force applied by the wire. However, if the weight for holding the wire is light, this deformation-preventing action will not be sufficiently exerted. On the other hand, if the weight is heavy, there is a problem that a large force is required for drawing the wire and smooth drawing is not performed. It is troublesome to pay close attention to the design of the weight for holding the wire.
[0007]
On the other hand, in order to enable the desired smooth pull-out with only the presser plate without using such a weight for holding the wire, it is solved to some extent by repeatedly examining the material surface such as the material and weight. However, the shape of the elastic inwardly facing piece 15 such as the shape, size, number, etc. has a great influence on effectively preventing abnormal pulling such as wire jumping, entanglement and jumping out. However, the reality is that this has not yet been clarified technically.
[0008]
The present invention has been made to solve such problems. Therefore, the main object of the present invention is to prevent the wire from jumping up and popping out when the wire for pail winding welding is pulled out. Another object of the present invention is to provide a welding wire pressing plate that can prevent the occurrence of entanglement between wires and can surely prevent the wires from being entangled.
[0009]
Another object of the present invention is to realize a stable wire drawing by making it possible to surely prevent the wire from jumping up and popping out only by a holding plate without using a weight for holding the wire which has been conventionally required. It is providing the pressing plate of the welding wire to obtain.
[0010]
Still another object of the present invention is to find a specific condition regarding the shape of the elastic inward piece in the holding plate, and thereby to appropriately maintain the force for pressing the wire by increasing the bending strength of the elastic inward piece. Therefore, the use of only the pressing plate prevents the occurrence of an abnormal state such as entanglement and realizes smooth wire feeding.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 of the present invention has a long strip shape compared to the outer cylinder circumferential length of the container in which the pail winding welding wire is accommodated, and A vertical wall portion that is in contact with the inner wall, and extends from the lower end of the vertical wall portion so as to bend inward at a predetermined interval, and from the bottom portion that continues to the lower end of the vertical wall portion, the apex angle portion of the tip portion A welding wire holding plate comprising a plurality of elastic inwardly facing pieces placed on the pail wound welding wire housed in the container, wherein the elastic inwardly facing pieces are The apex angle portion is formed in a substantially unequal triangular shape shifted in the drawing direction of the welding wire with respect to a reference line extending in a direction perpendicular to the plane of the elastic inward piece from the center point.
[0012]
When formed in this way, it becomes possible to hold the drawn wire with more elastic inward pieces compared to the conventional holding plate having no deviation in the apex portion with respect to the reference line, and smooth wire feeding is possible. In addition, it is possible to reduce the amount of wire slack between the wire drawing point on the storage container and the drawing start portion of the pail-wrapped laminated wire, thereby preventing the occurrence of kinks and tangles.
[0013]
The larger the amount of deviation of the apex angle portion with respect to the reference line, the greater the number of elastic inward pieces that hold down the drawn wire, but on the other hand, the force of holding down the wire decreases, causing tangling and entanglement of the wire. Therefore, as in the configurations of the inventions according to claims 2 to 5 of the present invention, a relational expression of 0.4 × L ≦ l ≦ L is established between the shift amount l and the side length L of the bottom portion. The crossing angle θ between the longer hypotenuse located on the upper side of the wire drawing direction and the reference line is 13 ° to 50 °, preferably 20 ° to 40 °, and the length of the elastic inwardly facing piece By setting each characteristic condition that the relational expression of W ≦ H ≦ 1.8 × W is satisfied between H and the lamination width W of the pail winding welding wire, It is possible to perform wire feeding with high stability.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of an embodiment of the present invention will be specifically described with reference to the accompanying drawings. In each drawing, FIG. 1 is a cross-sectional view of a container in which a pail winding welding wire is accommodated, FIG. 2 is a side view of a pressing plate, FIG. 3 is a plan view, and FIG. 4 is a plan view corresponding to FIG.
[0015]
In FIG. 1, reference numeral 1 denotes a container including an outer cylinder, for example, a bottomed upright cylindrical outer cylinder, in which twisted welding wires are stacked and accommodated in a pile winding shape in the inner space of the container 1. Reference numeral 2 denotes this pail winding welding wire. A holding plate 3 is placed on the upper end of a pail winding welding wire (hereinafter abbreviated as “wire”) 2 so as to prevent the wire from jumping up when the wire is pulled out.
[0016]
The presser plate 3 is preferably made of an elastic material, and is integrally formed into a desired shape including one vertical wall portion 4 and a plurality of elastic inward pieces 5. The vertical wall portion 4 has a strip shape slightly longer than the circumferential length of the outer cylinder of the container 1 and is a portion that comes into contact with the inner wall of the outer cylinder by surface contact. The plurality of elastic inwardly-moving pieces 5 bend and extend in a perpendicular direction inward from the lower end of the vertical wall portion 4 at a required interval, and the tip of the tip end portion is rounded from the bottom portion 5A continuous to the lower end of the vertical wall portion 4. It is a portion that is tapered toward the apex portion 5 </ b> B and is placed along the upper surface of the wire 2 in the container 1.
[0017]
In the holding plate 3 having such a structure, the elastic inwardly-moving piece 5 has a substantially unequal triangular shape, and extends from the center point of the bottom part 5A in the direction of the inwardly-piece 5 in a direction perpendicular to the base. The apex angle portion 5B is shifted in the drawing direction of the wire 2 with respect to the reference line 7, and the two hypotenuses between the base portion 5A and the apex angle portion 5B are based on the drawing direction of the wire 2. As shown, the upper hypotenuse 6A is longer than the lower hypotenuse 6B.
[0018]
As the material of the pressing plate 3, a material having an appropriate elasticity such as a polyester resin, a polypropylene resin, a vinyl chloride resin, etc. and having a sufficient strength against repeated bending is suitable. In addition, since there are many occasions where it is used in a relatively cold place, it is also preferable to use a material having sufficient strength under low temperature use conditions.
[0019]
By placing such a presser plate 3 on the upper surface of the wire 2 in the container 1 in an annular shape, the wire 2 moves in contact with the peripheral edge of the elastic inward piece 5 of the presser plate 3 from the upper end of the pail winding. Rotates and is pulled up. At this time, the elastic inwardly-moving piece 5 in contact with the wire 2 is subjected to some deformation, whereby the vertical wall portion 4 at the corresponding position is strongly brought into contact with the inner wall of the outer cylinder, and the wire 2 is pulled out longer than necessary. In addition, the presser plate 3 can be satisfactorily lowered, and thus the wire 2 can be pulled out smoothly and stably without entanglement or entanglement.
[0020]
By the way, the shape of the elastic inward piece 5 in the pressing plate 3 has a considerable influence on the entanglement and entanglement of the wire 2, and the conventional product in which the shift amount l of the apex portion 5B with respect to the reference line 7 is zero. As a result of various experiments, it was found that the product of the present invention in which the shift amount l is appropriately set is more effective in performing smooth wire feeding. The experimental results of examining the shift amount l, the bending strength of the elastic inward piece 5 and the smoothness of the wire feeding are as shown in Table 1 below.
[0021]
As is clear from [Table 1], if the displacement ratio (ratio of the displacement amount 1 and the side length L of the bottom portion 5A) is too large, such as 167%, the force for pressing the wire decreases, and the entanglement or entanglement occurs. In terms of the bending strength of the elastic inwardly facing piece 5 and the smoothness of the wire feeding, the shift ratio (intersection angle θ between the upper oblique side 6A and the reference line 7) is 17% (intersection angle θ). : 16 °) to a shift ratio of 150% (intersection angle θ: 46 °), and the effect is most remarkable at a shift ratio of about 67% (intersection angle θ: 30 °). understood.

【Example】
Embodiments of the present invention will be described below with reference to the accompanying drawings.
The presser plate 3 according to the present invention is formed in an end-band shape having a predetermined length, and can be used even when the diameter of the outer cylinder of the container 1 is slightly changed as compared with an endless annular one. There is an advantage that it does not take up space during transportation. And when setting to the container 1, it is used in an annular shape by overlapping both end portions. In this regard, the annular shape causes deformation such as bending of the elastic inward piece 5 in the vertical direction, and the wire feeding action becomes unstable. It is. In addition, conventionally, it is possible to save the trouble of connecting the end portions when setting the container 1. In addition, the elastic inward-facing piece 5 bends in the vertical direction because the attachment portion of the bottom portion 5A to the vertical wall portion 4 is a straight line. This is because the elastic inwardly facing piece 5 is easily bent by the warping force.

As for a specific mode of the presser plate 3 according to the present invention, for example, when the height of the vertical wall portion 4 is 55 mm, the side length L of the bottom portion 5A of the elastic inwardly facing piece 5 is 60 mm, and The overlap margin at both end portions when used in the above is set to 120 mm, which is twice the side length L, and the total length of the vertical wall portion 4 is selected to be substantially equivalent to the sum of the outer cylinder circumferential length of the container 1 and 120 mm. Is appropriate.
[0025]
The length H of the elastic inwardly-moving piece 5 (height of the apex angle portion 5B from the base portion 5A) and the lamination width W of the wire 2 (1/2 of the difference between the outer diameter φo and the inner diameter φi of the pail winding) are W ≦ It is desirable to satisfy the relational expression of H ≦ 1.8 × W, and H = 1.25W is the optimum condition. In general, if the length H of the elastic inwardly facing piece 5 is too short, the wire 2 may get over the elastic inwardly facing piece 5 and cause kinking or entanglement. 2 and the elastic inward piece 5 become stronger, causing damage to the elastic inward piece 5. Accordingly, it has been found that the range satisfying the above-mentioned formula is good, and the length H of the elastic inwardly facing piece 5 is optimal around 25% increase of the lamination width W of the wire 2.
[0026]
The figure which shows the aspect of the container 1 in which the wire 2 which concerns on this invention is accommodated by the top view about the relationship between the said crossing angle (theta) of the elastic inward piece 5 and the press to the wire 2 in the press plate 3 mounted in the annular | circular shape. 4 and FIG. 5 which is a plan view corresponding to FIG. 4 when using a conventional pressing plate will be described. Usually, the wire 2 to be drawn is once pressed against the inner wall of the container 1 at a position B on the front side of the ring about 180 ° with respect to the position i to be drawn and then drawn. Similarly, the pressing plate 3 is also pressed against the inner wall of the container 1 by the reaction force of the pulling-out force of the wire 2 at a position substantially corresponding to a position B approximately half a ring before the position A.
[0027]
However, it has been found that the position where the pressing plate 3 is pressed against the inner wall of the container 1 varies depending on the crossing angle θ. That is, as shown in the above [Table 1], it is apparent from the result of the experiment, but the angle between 16 ° and 46 ° is appropriate, and the position where the pressing plate 3 is pressed against the inner wall of the container 1 is as follows. Compared with that position in the case of the conventional pressing plate 13 , it is further away from the position (a) where the wire 2 is pulled out, and this makes the pressing of the pressing plate 3 smooth and improves the stability of wire feeding. .
[0028]
Although the present invention is configured as described above, it is possible to surely perform the smooth drawing of the wire by using only the pressing plate 3, but of course, this does not prevent the combined use of the weight for pressing the wire. Further, by forming the vertical wall portion 4 thicker than the elastic inward piece 5 to give its own weight, the presser plate 3 can be lowered with good followability with respect to the lowering of the wire 2. Such modifications are also included in the scope of the present invention.
[0029]
【The invention's effect】
The present invention has the above-described configuration and functions, and has an excellent effect in pulling out a welding wire stored in a container by being wound in a pile, without causing entanglement or entanglement. It is possible to smoothly pull out the welding wire sequentially and stably feed it to the welded portion.
