Abstract
Description
本発明は、線材の表面あらし、酸化スケール落とし、表面研磨、異物除去、バリ取り、丸み付け等を行う線材表面の加工装置に関する。 The present invention relates to an apparatus for processing the surface of a wire, which performs surface roughening, oxide scale removal, surface polishing, foreign matter removal, deburring, rounding, and the like.
一般的に、断面形状が円形、略円形、多角形、異形等である長尺物（「線材」ともいう）の表面加工を、バイト、研削ホイール、ブラシ、ベルトサンダ等を用いて行うことがあったが、特に断面寸法の小さい線材等の場合には、その外周を連続的にして一様に切削することが困難であった。 In general, surface processing of a long object (also referred to as “wire”) having a cross-sectional shape of a circle, a substantially circle, a polygon, an irregular shape, or the like is performed using a cutting tool, a grinding wheel, a brush, a belt sander, or the like. However, particularly in the case of a wire having a small cross-sectional dimension, it has been difficult to cut the outer periphery continuously and uniformly.
このため、従来、線材の酸化スケールや錆を除去する場合には酸洗法、潤滑剤や付着物を除去する場合には、アルカリ洗浄法、有機溶剤洗浄法等の化学的手法が用いられていた。また、機械加工の方法としては、対とされた弾性ローラ間に研磨材とともに線材を通過させる研削加工法が用いられていた（特許文献１）。 For this reason, conventionally, chemical methods such as an acid cleaning method and an organic solvent cleaning method have been used to remove oxide scale and rust of the wire, and to remove lubricants and deposits. It was. In addition, as a machining method, a grinding method is used in which a wire is passed along with an abrasive between a pair of elastic rollers (Patent Document 1).
しかし、前者の化学的手法では、大量の水を使用し、廃水処理や環境対策が必要となり、且つ設備が大規模なものとなるといった問題があり、さらに、線材同士が接触して、線材表面に一様に浸漬しない場合があり、このような場合には加工ムラが残ってしまうという問題があった。 However, in the former chemical method, there is a problem that a large amount of water is used, waste water treatment and environmental measures are required, and the facilities become large-scale. In such a case, there is a problem that uneven processing remains.
また、後者の機械的方法（特許文献１）の場合には、図９に示すように、弾性ローラ１０４へ研磨材を効率よく供給するために弾性ローラ１０４は横方向に並べて線材（長尺物）１０３を挟み込むようにされ、線材１０３は、上下方向に走行される。一般的に長尺物の生産ラインにおいては、床面より一定高さの水平線上を一直線に走行しながら加工されることが多いが、特許文献１の方法で加工するためにはリターンプーリ１０５などを用いて、図９に示すように、走行方向を上下方向に変え、弾性ローラの対の数の分だけ上下往復数を増やす必要がある。プーリ部品の増加に伴い装置が大型化してしまいスペースの確保が必要になるという問題があった。また、細い線材の加工ラインの場合毎分１０００ｍ程の高速度で走行させることがあり、リターンプーリを通過する際に大きな抵抗が発生し、加工ラインの線材走行駆動手段が大型化してしまい、さらに走行中に断線するおそれがあるという問題があった。 In the case of the latter mechanical method (Patent Document 1), as shown in FIG. 9, in order to efficiently supply the abrasive to the elastic roller 104, the elastic roller 104 is arranged side by side in the horizontal direction (long object). ) 103 is sandwiched, and the wire 103 travels in the vertical direction. In general, in a production line for long objects, it is often processed while traveling in a straight line on a horizontal line at a certain height from the floor surface. As shown in FIG. 9, it is necessary to change the traveling direction to the vertical direction and increase the number of vertical reciprocations by the number of elastic roller pairs. As the number of pulley parts increases, the apparatus becomes large and there is a problem that it is necessary to secure a space. Also, in the case of a thin wire rod processing line, it may be run at a high speed of about 1000 m per minute, a large resistance is generated when passing through the return pulley, and the wire rod travel driving means of the processing line becomes large, There was a problem of disconnection during traveling.
本発明の目的は、機械的方法で表面加工を可能として環境負荷を抑制するとともに、線材の走行に負担を与えることなく、高速で且つムラのない表面加工を可能とする線材表面の加工装置を提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a wire surface processing apparatus that enables surface processing by a mechanical method, suppresses environmental load, and enables high-speed and non-uniform surface processing without imposing a burden on the travel of the wire.

Moreover, since this invention implement | achieves surface processing with a mechanical structure, it can suppress environmental impact.
以下、本発明を適用した線材表面の加工装置１（以下、「加工装置１」という。）について図面を参照して説明する。本発明や以下の説明において、線材とは、断面形状が円形、略円形、多角形、異形等である長尺物を意味する。また、この線材として、ばね材料や電線等の金属製を想定するが、光ファイバ等のガラス繊維や、釣り糸等のナイロン製線や、その他樹脂製のものにも本発明は適用可能である。また、円錐状とは、円錐面や、円錐面を底面と平行な平面等の平面で切り取った形状を含むものとする。ここで、溶液とは、液体状態の均一な混合物を意味し、すなわち、一つの液体に一又は複数の他の物質（固体、液体又は気体）が溶解してできたものを意味するものとする。さらにこの溶液には、ゾル（コロイド溶液）も含まれるものとする。 A wire surface processing apparatus 1 to which the present invention is applied (hereinafter referred to as “processing apparatus 1”) will be described below with reference to the drawings. In the present invention and the following description, the wire means a long object whose cross-sectional shape is circular, substantially circular, polygonal, irregular, or the like. In addition, the wire is assumed to be made of a metal such as a spring material or an electric wire, but the present invention can also be applied to a glass fiber such as an optical fiber, a nylon wire such as a fishing line, or other resin. The conical shape includes a conical surface and a shape obtained by cutting the conical surface with a plane such as a plane parallel to the bottom surface. Here, the solution means a uniform mixture in a liquid state, that is, one obtained by dissolving one or more other substances (solid, liquid or gas) in one liquid. . Further, this solution includes a sol (colloidal solution).
図１に示す加工装置１は、図２に示す線材走行駆動手段２により走行される被処理製品である線材３の表面を加工する線材表面の加工装置である。この加工装置１は、複数の回転摺接体４を備える。この回転摺接体４は研磨材が供給される円錐状の摺接面５を有し、かつ、走行される線材３に対して、回転されながら該摺接面５を摺接させる。すなわち、被処理製品としての線材３は、後述のように研磨材が存在する回転摺接体４の摺接面５に接触走行されることで研磨加工が行われる。尚、回転摺接体４は、円錐形状でもよいが、ここでは、図４に示すような円錐台形状とされており、線材３を研磨する所謂ポリシャである。 A processing apparatus 1 shown in FIG. 1 is a wire surface processing apparatus that processes the surface of a wire 3 that is a product to be processed that is traveled by the wire travel driving means 2 shown in FIG. The processing apparatus 1 includes a plurality of rotating sliding contacts 4. The rotating sliding contact body 4 has a conical sliding contact surface 5 to which an abrasive is supplied, and causes the sliding contact surface 5 to slidably contact the traveling wire rod 3 while being rotated. That is, the wire 3 as the product to be processed is subjected to the polishing process by being brought into contact with the sliding contact surface 5 of the rotary sliding contact body 4 on which the abrasive is present as will be described later. The rotating sliding contact body 4 may have a conical shape, but here, it has a truncated cone shape as shown in FIG. 4 and is a so-called polisher for polishing the wire 3.
また、加工装置１は、回転摺接体４を回転軸４ａと平行な方向Ｄへ駆動して移動させる摺接体駆動手段として第１及び第２摺接体駆動手段６，７を備えている。 Further, the processing apparatus 1 includes first and second sliding contact body driving means 6 and 7 as sliding contact body driving means for driving and moving the rotating sliding contact body 4 in a direction D parallel to the rotation axis 4a. .
複数の回転摺接体４は、図３に示すように、線材３の上方から摺接面５を摺接させる一又は複数の回転摺接体（以下、「上側回転摺接体４Ｇ１，４Ｇ２」ともいう。）と、線材３の下方から摺接面５を摺接させる一又は複数の回転摺接体（以下、「下側回転摺接体４Ｇ３，４Ｇ４」ともいう。）とを有している。尚、本装置の変形例として、これらの回転摺接体４Ｇ１〜４Ｇ４に加えて斜め方向から摺接するような回転摺接体を追加するように構成しても良い。 As shown in FIG. 3, the plurality of rotating sliding contact bodies 4 are one or a plurality of rotating sliding contact bodies (hereinafter referred to as “upper rotating sliding contact bodies 4G1, 4G2”) that make the sliding contact surface 5 slide from above the wire 3. And one or more rotating sliding contact bodies (hereinafter also referred to as “lower rotating sliding contact bodies 4G3 and 4G4”) that slide the sliding contact surface 5 from below the wire 3. Yes. As a modification of the present apparatus, a rotary sliding contact body that slides in an oblique direction in addition to the rotational sliding contact bodies 4G1 to 4G4 may be added.
この複数の回転摺接体４は、回転軸４ａが互いに平行となるように配置されている（図５参照）。そして、複数の回転摺接体４は、摺接面５の円錐状の先細る向きが反対方向のものが混在するように配置されている。このような構成により、後述のように、線材３に対して複数の方向から摺接でき、加工性能が向上する。ここで、先細る向きとは、回転軸に直交する断面が円形とされているが、径が小さくなる方向に向いていることを示す。すなわち、ここでは回転摺接体４は図４等に示すように円錐台であるので、底面が大きい側である大底面４ｃ側から底面が小さい側である小底面４ｂ側に向いていることを示す。先細る向きが反対方向とは、径が小さくなる方向が異なるように配置されていることを示し、換言すると図３に示すように、軸方向の片側から見たときに大底面と小底面が混在することを示す。具体的に加工装置１においては、この先細る方向が、図中Ｄ２で示す摺接体駆動手段側か、若しくは、図中Ｄ１で示す通線作業側（作業者側）とされている。尚図中Ｄｕは、装置が配置された状態の上側を示し、Ｄｄは、下側を示す。 The plurality of rotating sliding contact bodies 4 are arranged such that the rotating shafts 4a are parallel to each other (see FIG. 5). The plurality of rotating sliding contact bodies 4 are arranged so that the conical tapering directions of the sliding contact surfaces 5 are opposite to each other. With such a configuration, as described later, the wire 3 can be slidably contacted from a plurality of directions, and the processing performance is improved. Here, the tapering direction indicates that the cross section orthogonal to the rotation axis is circular, but the diameter is decreasing. That is, here, the rotating sliding contact 4 is a truncated cone as shown in FIG. 4 and the like, and therefore, it is directed from the large bottom surface 4c side, which is the larger bottom surface side, to the small bottom surface 4b side, which is the smaller bottom surface side. Show. When the taper direction is opposite to the opposite direction, it indicates that the direction in which the diameter decreases is different. In other words, as shown in FIG. 3, when viewed from one side in the axial direction, the large bottom surface and the small bottom surface are Indicates mixing. Specifically, in the processing apparatus 1, this tapering direction is on the sliding contact body drive means side indicated by D2 in the drawing, or on the line work side (operator side) indicated by D1 in the drawing. In the drawing, Du indicates the upper side of the state where the apparatus is arranged, and Dd indicates the lower side.
さらにここでは、線材の上方から摺接面を摺接させる回転摺接体４Ｇ１，４Ｇ２は、複数であり、摺接面５の円錐状の先細る向きが反対方向のものが混在するように配置され、線材の下方から摺接面を摺接させる回転摺接体４Ｇ３，４Ｇ４は、複数であり、摺接面５の円錐状の先細る向きが反対方向のものが混在するように配置されている。このような構成により、後述の図６等に示すように、線材３に対して４つの方向から摺接させることができ、線材３の断面全周を満遍なく加工することができ、加工性能が著しく向上する。 Furthermore, here, there are a plurality of rotating sliding contact bodies 4G1 and 4G2 that slide the sliding contact surface from above the wire, and the conical tapering directions of the sliding contact surface 5 are arranged in a direction opposite to each other. There are a plurality of rotating sliding contact bodies 4G3 and 4G4 for sliding the sliding contact surface from below the wire rod, and the sliding contact surfaces 5 are arranged so that the conical tapering directions are opposite to each other. Yes. With such a configuration, as shown in FIG. 6 and the like which will be described later, the wire 3 can be slidably contacted from four directions, the entire circumference of the wire 3 can be processed evenly, and the processing performance is remarkable. improves.
尚、前記線材の上方から摺接面を摺接させる回転摺接体のうち、先細る向きが第１の方向Ｄ１であるものを第１群の回転摺接体４Ｇ１とし、先細る向きが前記第１の方向Ｄ１の反対方向である第２の方向Ｄ２であるものを第２群の回転摺接体４Ｇ２とする。また、前記線材の下方から摺接面を摺接させる回転摺接体のうち、先細る向きが前記第２の方向Ｄ２であるものを第３群の回転摺接体４Ｇ３とし、先細る向きが前記第１の方向Ｄ１であるものを第４群の回転摺接体４Ｇ１とする。ここでは、各群の回転摺接体は、２個ずつであるが、１個でも３個以上（複数個）でもよい。 Of the rotating sliding contact bodies that make sliding contact with the sliding contact surface from above the wire rod, the tapering direction is the first direction D1, and the first group of rotating sliding contact bodies 4G1 is used. The second direction D2 which is the direction opposite to the first direction D1 is defined as a second group of rotating sliding contact bodies 4G2. Further, among the rotating sliding contact bodies that make sliding contact with the sliding contact surface from below the wire rod, the tapering direction is the second direction D2, which is the third group of rotating sliding contact bodies 4G3, and the tapering direction is The first direction D1 is defined as a fourth group of rotating sliding contact bodies 4G1. Here, the number of the rotating sliding contact bodies in each group is two, but may be one or three or more (a plurality).
第１，第２摺接体駆動手段６，７は、第１群及び第３群の回転摺接体４Ｇ１，４Ｇ３を一方向に駆動しているときに、第２群及び第４群の回転摺接体４Ｇ２，４Ｇ４を反対方向に駆動するように往復移動させる。具体的に、第１，第２摺接体駆動手段６，７は、それぞれ、固定部１１と、固定部１１に対してＤ１，Ｄ２方向に可動する可動部１２と、可動部１２をＤ１，Ｄ２方向に可動自在となるようにガイドするガイドロッド１３と、可動部１２をＤ１，Ｄ２方向に駆動するシリンダ１４とを備える。尚、図５は、第２摺接体駆動手段７を示す図であるが、第１摺接体駆動手段６も同様の構成を有している。このように、各回転摺接体４Ｇ１〜４Ｇ４は、中心軸の一方側が第１、第２摺接体駆動手段６，７の可動部１２に接続され、中心軸の他方側が線材３を当該加工装置１にセットするために開放されている。図中Ｄ２が、摺接体駆動手段側であり、Ｄ１が線材セット側（作業者側）である。 The first and second sliding contact body driving means 6 and 7 rotate the second group and the fourth group while driving the first and third group rotational sliding contact bodies 4G1 and 4G3 in one direction. The sliding contacts 4G2 and 4G4 are reciprocated so as to be driven in opposite directions. Specifically, the first and second sliding contact body drive means 6, 7 are respectively a fixed portion 11, a movable portion 12 movable in the directions D 1 and D 2 with respect to the fixed portion 11, and a movable portion 12 as D 1, respectively. A guide rod 13 that guides the movable portion 12 so as to be movable in the D2 direction and a cylinder 14 that drives the movable portion 12 in the D1 and D2 directions are provided. FIG. 5 is a diagram showing the second sliding contact body driving means 7, but the first sliding contact body driving means 6 has the same configuration. As described above, each of the rotary sliding contact bodies 4G1 to 4G4 has one side of the central axis connected to the movable portion 12 of the first and second sliding contact body driving means 6 and 7, and the other side of the central axis processing the wire 3 Open to set in device 1. In the figure, D2 is the sliding contact body drive means side, and D1 is the wire rod set side (operator side).
第１摺接体駆動手段６は、第１群及び第３群の回転摺接体４Ｇ１，４Ｇ３を１セットとなるように固定部１１に取り付けており、これらの回転摺接体４Ｇ１，４Ｇ３を同時に、Ｄ１方向又はＤ２方向に駆動することができる。この１セットとなる第1群及び第３群の回転摺接体４Ｇ１，４Ｇ３は、走行する線材３を互いに挟み込む配置とされている。第２摺接体駆動手段７は、第２群及び第４群の回転摺接体４Ｇ２，４Ｇ４を１セットとなるように固定部１１に取り付けており、これらの回転摺接体４Ｇ２，４Ｇ４を同時に、Ｄ１方向又はＤ２方向に駆動することができる。この１セットとなる第２群及び第４群の回転摺接体４Ｇ２，４Ｇ４は、走行する線材３を互いに挟み込む配置とされている。換言すると、第１群及び第３群は、互いに対向する部分の母線が平行でＤ２方向（摺接体駆動手段側）に向けて（斜め）上方向きとなる回転摺接体の組み合わせである。第２群及び第４群は、互いに対向する部分の母線が平行でＤ２方向に向けて（斜め）下方向きとなる回転摺接体の組み合わせである。 The first sliding contact body driving means 6 has the first and third groups of rotating sliding contact bodies 4G1 and 4G3 attached to the fixed portion 11 so as to form one set, and these rotating sliding contact bodies 4G1 and 4G3 are attached. At the same time, it can be driven in the direction D1 or D2. The 1st group and the 3rd group of rotation sliding contact bodies 4G1 and 4G3 which constitute this set are arranged so as to sandwich the traveling wire 3 therebetween. The second sliding contact body driving means 7 has the second and fourth groups of rotational sliding contact bodies 4G2 and 4G4 attached to the fixed portion 11 so as to form one set, and these rotational sliding contact bodies 4G2 and 4G4 are attached. At the same time, it can be driven in the direction D1 or D2. The second group and the fourth group of rotating sliding contact bodies 4G2 and 4G4, which form one set, are arranged so as to sandwich the traveling wire 3 therebetween. In other words, the first group and the third group are a combination of rotating sliding contact bodies in which the buses of the portions facing each other are parallel and face upward (obliquely) in the D2 direction (sliding contact body driving means side). The second group and the fourth group are a combination of rotating sliding contact bodies in which the buses of the portions facing each other are parallel and face downward (diagonally) in the D2 direction.
第１及び第２の摺接体駆動手段６，７は、それぞれ駆動する回転摺接体をＤ１，Ｄ２方向のうち反対方向に同期するように駆動することで図６（ａ）〜図６（ｃ）に示すように、線材３に対して４方向から摺接面を摺接させ線材３の断面全周を満遍なく加工可能な状態で、且つ摺接面の線材３に摺接させる位置を変更することができる。これにより、各回転摺接体４Ｇ１〜４Ｇ４の部分的な磨耗を回避でき、加工性能を長く保持することができ、装置の長寿命化を実現できる。尚、ここでは、摺接体駆動手段を２つ設け、一方の可動部に第１群及び第３群を設け、他方の可動部に第２群及び第４群を設けるようにしたが、これに限られるものでなく、例えば各群毎の摺接体駆動手段を設けても、上述のように同期するように駆動すれば同様の効果が得られる。 The first and second sliding contact body driving means 6 and 7 drive the rotating sliding contact bodies to be driven so as to synchronize with the opposite directions of the D1 and D2 directions, respectively. As shown in c), the slidable contact surface is slidably contacted with the wire 3 from four directions, and the position of the slidable contact surface in contact with the wire 3 is changed in a state where the entire circumference of the wire 3 can be processed evenly. can do. Thereby, the partial wear of each rotary sliding contact body 4G1-4G4 can be avoided, processing performance can be kept long, and the lifetime improvement of an apparatus is realizable. Here, two sliding contact body drive means are provided, the first group and the third group are provided on one movable part, and the second group and the fourth group are provided on the other movable part. For example, even if the sliding contact body driving means for each group is provided, the same effect can be obtained if they are driven in synchronism as described above.
ところで、回転摺接体４は、回転駆動手段としてのモータ２１及び駆動歯車２２により、回転駆動されている。回転駆動方向は、線材３の駆動方向と同一でも反対でも問題ないが、ここでは例えば同一方向とされている。具体的に、モータ２１は、第１及び第２摺接体駆動手段６，７のそれぞれに１つ設けられており、駆動伝達手段である複数の駆動歯車２２を回転させる。駆動歯車２２は、回転摺接体４の個数と同じ数だけ設けられており、モータ２１により発生された回転力を回転摺接体４に伝達して、各回転摺接体４を回転軸４ａを中心に回転させる。 By the way, the rotary sliding contact body 4 is rotationally driven by a motor 21 and a drive gear 22 as rotational drive means. The rotational drive direction may be the same as or opposite to the drive direction of the wire 3, but here, for example, the same direction. Specifically, one motor 21 is provided for each of the first and second sliding contact body drive means 6 and 7 and rotates a plurality of drive gears 22 as drive transmission means. The drive gears 22 are provided in the same number as the number of the rotating sliding contact bodies 4, and the rotational force generated by the motor 21 is transmitted to the rotating sliding contact bodies 4 so that each rotating sliding contact body 4 is rotated by the rotating shaft 4a. Rotate around.
回転摺接体４は、ショア硬さが４０〜９０の弾性体で前記摺接面を形成する部分が形成されている（ショア硬さ試験方法ＪＩＳ Ｚ２２４６）。回転摺接体４は、線材３の走行軌跡を挟み込むように配置される。これより低い（軟らかい）と耐摩耗性が悪く、交換頻度が高くなるほか線材（長尺物）３への押し付け力を得られにくく、加工性も低下し、逆に大きい（硬い）と回転摺接体４が充分に歪まないことから線材３の断面になじまず、長尺物Ｗの断面のうち部分的に加工されない部位が生じてしまう恐れがあるからである。例えば、回転摺接体４としては、ショア硬さ６０程度のブタジエンゴムが用いられ、最大外径が１００ｍｍであり、毎分１０回転の回転数で回転される。このとき、第１及び第２摺接体駆動手段６，７により回転摺接体の軸方向の移動は、６０秒で１往復とした。 The rotating sliding contact body 4 is formed of an elastic body having a Shore hardness of 40 to 90 and forming the sliding contact surface (Shore hardness test method JIS Z2246). The rotary sliding contact body 4 is disposed so as to sandwich the travel locus of the wire 3. If it is lower (softer), the wear resistance will be worse, the replacement frequency will be higher, the pressing force on the wire (long object) 3 will be difficult to obtain, workability will also be reduced, and conversely if it is larger (hard), This is because the contact body 4 is not sufficiently distorted, so that there is a possibility that a part that is not partially processed in the cross section of the long object W may be generated without adapting to the cross section of the wire 3. For example, the rotating sliding contact body 4 is made of butadiene rubber having a Shore hardness of about 60, has a maximum outer diameter of 100 mm, and is rotated at a rotational speed of 10 revolutions per minute. At this time, the first and second sliding contact body driving means 6 and 7 moved the rotational sliding contact in the axial direction once in 60 seconds.
また、加工装置１は、複数の研磨材供給部８と、複数のバインダ供給部９とを備える。複数の研磨材供給部８は、複数の回転摺接体４のそれぞれの上方に配置され、摺接面５に上方から研磨材を供給する。研磨材供給部８は、例えばパイプ状の供給部を有しており、この供給部から円錐状の摺接面５に研磨材を供給する。研磨材の供給は、連続又は断続で行われる。研磨材としては、例えば粒度＃２２０のシリコンカーバイド製のものを用い、供給量としては、４０秒おきに各回転摺接体４に１ｃｃずつ供給する。この場合、研磨材切出しヘッドの往復により研磨材一定時間おきに定量に切り出す装置（図示せず）を用いることができる。尚、研磨材としては、アルミナ、セラミックス、ガラス粉、シリカ粉、金属粉等から選ばれる単体又は混合物であっても良い。 Further, the processing apparatus 1 includes a plurality of abrasive supply units 8 and a plurality of binder supply units 9. The plurality of abrasive supply units 8 are arranged above the plurality of rotating sliding contacts 4 and supply the abrasive to the sliding contact surface 5 from above. The abrasive supply unit 8 has, for example, a pipe-shaped supply unit, and supplies the abrasive to the conical sliding contact surface 5 from this supply unit. The supply of the abrasive is performed continuously or intermittently. As the abrasive, for example, a silicon carbide product having a particle size of # 220 is used, and the supply amount is 1 cc to each rotating sliding contact 4 every 40 seconds. In this case, an apparatus (not shown) for cutting out the abrasive material at regular intervals by reciprocating the abrasive material cutting head can be used. The abrasive may be a single substance or a mixture selected from alumina, ceramics, glass powder, silica powder, metal powder and the like.
複数のバインダ供給部９は、摺接面５に研磨材を付着させるための液体又は溶液を供給させるものである。ここでは、バインダ供給部９は、回転摺接体４の上方及び下方に設けられ、バインダを霧状に若しくは直接、且つ連続若しくは断続的に供給する。ここでは、バインダ供給部９は、例えば図示しない圧縮エア源及びバインダタンクに接続された気液混合ノズルである。バインダとしては、水を用い、供給量としては、摺接面５に５秒噴射と１分停止とを繰り返す動作により供給した。尚、バインダは、寒天、糖類などの高分子有機物などの水溶液であって、研磨材を摺接面５に付着することができれば良い。さらにバインダにより摺接面５に付着した研磨材は、線材３との接触により脱落する程度の付着力であれば、加工に使われた研磨材の脱落と新たな研磨材の供給とを繰返すことが可能であり、加工程度を均一にすることができる。 The plurality of binder supply units 9 supply a liquid or a solution for attaching an abrasive to the sliding contact surface 5. Here, the binder supply unit 9 is provided above and below the rotary sliding contact body 4 and supplies the binder in the form of a mist or directly and continuously or intermittently. Here, the binder supply unit 9 is, for example, a gas-liquid mixing nozzle connected to a compressed air source (not shown) and a binder tank. Water was used as the binder, and the supply amount was supplied by repeating the operation of spraying on the sliding contact surface 5 for 5 seconds and stopping for 1 minute. The binder is an aqueous solution of a high molecular organic substance such as agar or saccharide, and it is sufficient that the abrasive can adhere to the sliding contact surface 5. Further, if the abrasive that adheres to the sliding contact surface 5 by the binder has an adhesive force that can be removed by contact with the wire 3, the removal of the abrasive used for processing and the supply of new abrasive are repeated. It is possible to make the degree of processing uniform.
また、ここでは、研磨材供給部８及びバインダ供給部９を設けるように構成したが、研磨材供給部から、研磨材にバインダを既に混合したスラリー状の研磨材を供給するようにしても同様の効果が得られる。 Here, the configuration is such that the abrasive supply unit 8 and the binder supply unit 9 are provided. However, the same applies to the case where a slurry-like abrasive in which the binder is already mixed with the abrasive is supplied from the abrasive supply unit. The effect is obtained.
さらに、加工装置１を構成する回転摺接体の表面に研磨材が練り込まれて付着されているようにしてもよい。換言すると、回転摺接体は、摺接面を形成する部分が研磨材、又は研磨材が分散された材料により形成されていてもよい。すなわち、本発明においては、回転摺接体の摺接面には研磨材が存在するように構成すればよい。すなわち、その態様としては、まず、上述の図１〜図６等を用いて説明したような、弾性体からなる回転摺接体の摺接面に外部から研磨材を供給させる機構を併せ持つようなものがある。また、その態様として、研磨材を焼成して形成され、例えばディスクグラインダの砥石のように回転摺接体全体が研磨材によりなるものがある。さらに、その態様として、弾性体に研磨材を練り込んで分散配合されるもので、砂消しゴムのように、弾性力があって線材表面に密着でき、表面の研磨材により研削力を併せ持つものがある。 Further, an abrasive may be kneaded and adhered to the surface of the rotary sliding contact body constituting the processing apparatus 1. In other words, the rotating sliding contact body may be formed of an abrasive or a material in which the abrasive is dispersed in a portion that forms the sliding contact surface. That is, in the present invention, the abrasive may be configured to exist on the sliding contact surface of the rotary sliding contact body. That is, as the mode, first, as described with reference to FIGS. 1 to 6 and the like, a mechanism for supplying an abrasive from the outside to the sliding contact surface of the rotating sliding contact body made of an elastic body is also provided. There is something. In addition, as an aspect thereof, there is one that is formed by firing an abrasive, and the entire rotary sliding contact body is made of an abrasive, such as a grinder of a disc grinder. Further, as an aspect thereof, an abrasive is kneaded into an elastic body and dispersed and blended, and like a sand eraser, there is an elastic force that can be adhered to the surface of the wire, and also has grinding power by the surface abrasive. is there.
以上のように構成された加工装置１においては、線材（長尺物）３を走行させることにより、線材は、研磨材の存在する回転摺接体４の摺接面５に接触することによって、線材３の表面は、従来のように走行方向を変えることなく水平状態で走行しながら研磨加工がなされる。 In the processing apparatus 1 configured as described above, by causing the wire (long object) 3 to travel, the wire comes into contact with the sliding contact surface 5 of the rotary sliding contact body 4 where the abrasive is present, The surface of the wire 3 is polished while traveling in a horizontal state without changing the traveling direction as in the prior art.
本発明を適用した加工装置１は、円錐状の摺接面５を有し、且つ、走行される線材３に対して回転されながら該摺接面を摺接させる複数の回転摺接体４を備え、複数の回転摺接体４は、線材の上方から摺接面を摺接させる一又は複数の回転摺接体と、線材の下方から摺接面を摺接させる一又は複数の回転摺接体とを有するように構成した点に特徴を有する。加工装置１は、回転摺接体の配置及び摺接面の形状を上述のようにすることで、線材３の走行に負担を与えることなく、高速で且つムラのない表面加工を実現する。また、該加工装置１は機械的な構成で表面加工を実現するので、環境負荷を抑制できる。 The processing apparatus 1 to which the present invention is applied has a conical sliding contact surface 5 and a plurality of rotating sliding contact bodies 4 that make sliding contact with the sliding contact surface while being rotated with respect to the traveling wire 3. And the plurality of rotating sliding contact bodies 4 include one or more rotating sliding contact bodies that make sliding contact with the sliding contact surface from above the wire, and one or more rotational sliding contacts that make sliding contact with the sliding contact surface from below the wire rod. It is characterized in that it is configured to have a body. The processing apparatus 1 realizes high-speed and non-uniform surface processing without imposing a burden on the travel of the wire 3 by making the arrangement of the rotating sliding contact body and the shape of the sliding contact surface as described above. Moreover, since this processing apparatus 1 implement | achieves surface processing with a mechanical structure, it can suppress environmental impact.
また、加工装置１によれば、ポリシャである回転摺接体４の形状と配置を工夫して線材３の走行方向を略水平に保った状態で、線材表面を均一な加工が可能であり、さらに、高速加工が可能であるという利点がある。さらに、従来に比較して線材を上方へ持ち上げるための部品が不要となり、部品点数が少なくなるほか、高所での通線作業もなくなり、操作性も向上する。 Further, according to the processing apparatus 1, the surface of the wire rod can be uniformly processed in a state in which the shape and arrangement of the rotating sliding contact body 4 that is a polisher is devised to keep the traveling direction of the wire rod 3 approximately horizontal, Furthermore, there is an advantage that high-speed processing is possible. In addition, parts for lifting the wire upward are not required compared to the prior art, the number of parts is reduced, and there is no need for wiring work at high places, improving operability.
また、加工装置１は、研磨材供給部８と、バインダ供給部９とにより回転摺接体４の摺接面５に研磨材を供給し続けることができ、線材（長尺物）を先端から末端まで加工品質が変化しない状態で連続加工することができる。 Further, the processing apparatus 1 can continue to supply the abrasive to the sliding contact surface 5 of the rotating sliding contact body 4 by the abrasive supply unit 8 and the binder supply unit 9, and the wire (long object) can be supplied from the tip. Continuous processing can be performed without changing the processing quality to the end.
さらに、加工装置１は、回転摺接体４がショア硬さ４０〜９０の弾性体で摺接面５を形成したので、適度に変形して線材３の大部分を覆うことができ、ムラがなくなるように加工することができる。 Furthermore, since the rotating sliding contact body 4 formed the sliding contact surface 5 with the elastic body of Shore hardness 40-90, the processing apparatus 1 can deform | transform moderately and can cover most of the wire rod 3, and unevenness | corrugation is carried out. It can be processed to disappear.
また、加工装置１は、線材３の上方から摺接面を摺接させる回転摺接体４Ｇ１，４Ｇ２が、摺接面５の円錐状の先細る向きが反対方向のものが混在するように配置され、線材３の下方から摺接面を摺接させる回転摺接体４Ｇ３，４Ｇ４が、摺接面５の円錐状の先細る向きが反対方向のものが混在するように配置されていることにより、線材３に直交する断面において、線材３を抱え込む状態となり、加工時に線材３の振動によって発生する可能性のある脱落を抑制することができる。 Moreover, the processing apparatus 1 arrange | positions so that the rotation sliding contact bodies 4G1 and 4G2 which slidably contact a sliding contact surface from the upper direction of the wire 3 may have the conical taper direction of the sliding contact surface 5 opposite direction. The rotating sliding contact bodies 4G3 and 4G4 for sliding the sliding contact surface from below the wire rod 3 are arranged so that the conical tapering directions of the sliding contact surface 5 are in opposite directions. In the cross section orthogonal to the wire 3, the wire 3 is held, and dropout that may occur due to vibration of the wire 3 during processing can be suppressed.
また、加工装置１は、摺接体駆動手段が第１群及び第３群の回転摺接体４Ｇ１，４Ｇ３を一方向に駆動しているときに、これと同期して第２群及び第４群の回転摺接体４Ｇ２，４Ｇ４を反対方向に駆動するように往復移動させていることにより、線材３が各回転摺接体４の母線上を往復することとなり、局部磨耗を抑制して、長寿命化を実現できる。 Further, when the sliding contact body driving means drives the first and third group rotary sliding contact bodies 4G1 and 4G3 in one direction, the processing apparatus 1 synchronizes with the second group and the fourth group. By reciprocating the rotary sliding contact bodies 4G2, 4G4 of the group so as to drive in the opposite direction, the wire rod 3 reciprocates on the bus bar of each rotary sliding contact body 4, and suppresses local wear. Long life can be realized.
また、加工装置１において、回転摺接体４は作業者側Ｄ１においてスペースを確保でき、その交換作業が簡便になるほか、回転摺接体４の形状の特徴を生かして単純な往復運動（摺接体駆動手段による回転摺接体の軸方向への移動動作）をさせるだけで、回転摺接体４の局部磨耗もなくすことができ、交換頻度も減少させることができ、ランニングコストを低減させることを実現する。 Further, in the processing apparatus 1, the rotary sliding contact body 4 can secure a space on the operator side D <b> 1, and the replacement work is simplified, and a simple reciprocating motion (sliding motion) is made by taking advantage of the shape of the rotary sliding contact body 4. By simply moving the rotating sliding contact body in the axial direction by the contact body driving means, local wear of the rotating sliding contact body 4 can be eliminated, the replacement frequency can be reduced, and the running cost can be reduced. Realize that.
次に、図１〜図６に示す加工装置１の変形例である加工装置３１について、図７を用いて説明する。加工装置３１は、回転摺接体４の配置を変更したことを除いて、上述の加工装置１と同様の構成とされている。図７（ａ）及び図７（ｂ）に示すように加工装置１は、線材走行方向から見たときに、回転摺接体は、その対向する母線が一致するか若しくは線材の幅分以下の隙間を有するように配置されている。ここで、線材走行方向から見たとは、線材の断面を含む平面における関係を意味し、例えば図７（ｂ）や図７（ｂ）に示す関係である。また、線材の幅とは、該母線の対向方向における幅を意味する。すなわち、図７（ｂ）は、第１群及び第３群の右側面図を示しているが、第１群及び第３群の回転摺接体４Ｇ１、４Ｇ３は、その対向する母線が略一致するように配置されることで、上述したように、当該部分で線材３を挟んだ状態で摺接して加工することを可能とする。第２群及び第４群についてもその対向する母線の方向が異なることを除いて同様の配置とされている。これに対して、図７（ｃ）及び図７（ｄ）に示す加工装置３１は、対向配置された第１群及び第３群が互いにラップするように上下方向に近接するように移動され、同様に、対向配置された第２群及び第４群が互いにラップするように上下方向に近接するように移動された状態で配置されて構成されている。尚、図７（ｄ）は、図７（ｂ）と同様に、第１群及び第３群の右側面図を示しており、領域Ｘ部分がラップした状態（重なる領域を有する状態）となっているが、第２群及び第４群も同様の関係となっている。 Next, a processing apparatus 31 which is a modification of the processing apparatus 1 shown in FIGS. 1 to 6 will be described with reference to FIG. The processing device 31 has the same configuration as the processing device 1 described above except that the arrangement of the rotary sliding contact body 4 is changed. As shown in FIGS. 7A and 7B, when the processing apparatus 1 is viewed from the wire travel direction, the rotating sliding contact body has the opposite busbars matching or less than the wire width. It arrange | positions so that it may have a clearance gap. Here, seeing from the wire travel direction means a relationship in a plane including a cross section of the wire, for example, the relationship shown in FIGS. 7B and 7B. Moreover, the width | variety of a wire means the width | variety in the opposing direction of this bus-line. That is, FIG. 7 (b) shows the right side view of the first group and the third group, but the rotating sliding contact bodies 4G1, 4G3 of the first group and the third group are substantially coincident with each other. By arrange | positioning in this way, as mentioned above, it becomes possible to carry out a sliding contact in the state which pinched | interposed the wire 3 in the said part. The second group and the fourth group have the same arrangement except that the directions of the buses facing each other are different. On the other hand, the processing device 31 shown in FIG. 7C and FIG. 7D is moved so as to be close to each other in the vertical direction so that the first group and the third group that are arranged to face each other overlap each other. Similarly, the second group and the fourth group that are arranged to face each other are arranged so as to be moved close to each other so as to overlap each other. FIG. 7D shows the right side view of the first group and the third group, as in FIG. 7B, and the region X is in a wrapped state (a state having overlapping regions). However, the second group and the fourth group have the same relationship.
このように、加工装置３１は、対向配置される回転摺接体が、線材３の走行方向から投影したときに、その摺接部分において重なる領域を有するように配置されている。具体的に対向配置される第１群及び第３群の回転摺接体４Ｇ１，４Ｇ３は、図７（ｄ）に示すようにその摺接面５付近の部分（摺接部分）において重なる領域Ｘを有した状態で配置されている。同様に、対向配置される第２群及び第４群の回転摺接体４Ｇ２，４Ｇ４は、図示しないが、摺接部分において重なる領域を有した状態で配置されている。尚、対向配置される回転摺接体とは、線材の上方から摺接面を摺接させる回転摺接体と、この回転摺接体と先細る向きが反対方向であって且つ線材の下方から摺接面を摺接させる回転摺接体とを一組としたものである。 As described above, the processing device 31 is disposed so that the rotating sliding contact bodies arranged opposite to each other have an overlapping region at the sliding contact portion when projected from the traveling direction of the wire 3. Specifically, the first group and the third group of rotating sliding contact bodies 4G1 and 4G3 opposed to each other overlap with each other in a region X in the vicinity of the sliding contact surface 5 (sliding contact portion) as shown in FIG. It is arranged in a state having. Similarly, the second group and the fourth group of rotating sliding contact bodies 4G2 and 4G4 arranged to face each other are arranged in a state having an overlapping region at a sliding contact portion, although not shown. Note that the rotating sliding contact body arranged oppositely is a rotating sliding contact body that makes sliding contact with the sliding contact surface from above the wire, and a direction tapering to the rotating sliding contact body is in the opposite direction and from below the wire rod. The rotary sliding contact body that makes sliding contact with the sliding contact surface is a set.
図７（ｃ）及び図７（ｄ）に示す加工装置３１は、上述の加工装置１の効果に加えて、図７（ｃ）に示すように線材３の長さ方向において各回転摺接体４に接触する部分が増加し、換言すると線材３が各回転摺接体４に接触する時間が増加し、これにより、研削力が向上し、加工性能が向上する。 In addition to the effects of the processing apparatus 1 described above, the processing apparatus 31 shown in FIGS. 7C and 7D has each rotating sliding contact body in the length direction of the wire 3 as shown in FIG. The part which contacts 4 increases, in other words, the time when the wire 3 contacts each rotary sliding contact body 4 increases, and thereby the grinding force is improved and the machining performance is improved.
尚、本発明は、これに限られるものではなく、例えば、線材の上方側から摺接する回転摺接体群（上述では第１群及び第２群）と、線材の下方側から摺接する回転摺接体群（上述では第３群及び第４群）との、いずれか一方及び両方を、近接離間する方向、すなわち上下方向に駆動させる上下駆動機構を設けるように構成してもよい。かかる上下駆動機構を有する加工装置は、上述した加工装置１による加工と、加工装置３１による加工とを切り換えて行うことができるとともに、線材の種類（大きさや太さ）に応じてその加工程度を調整することができるという効果を奏する。 The present invention is not limited to this. For example, a rotating sliding contact group (in the above-described first group and second group) that slides from the upper side of the wire, and a rotary sliding that slides from the lower side of the wire. You may comprise so that the up-and-down drive mechanism which drives any one and both with a contact group (in the above-mentioned 3rd group and 4th group) to the direction to adjoin and separate, ie, an up-down direction, may be provided. A processing apparatus having such a vertical drive mechanism can perform switching between the processing by the processing apparatus 1 and the processing by the processing apparatus 31 described above, and the degree of processing according to the type (size and thickness) of the wire rod. There is an effect that it can be adjusted.
また、上述した加工装置１，３１等を構成する回転摺接体は、上述した図１〜図７を用いて説明した回転摺接体４に限られるものではなく、例えば、図８（ｂ）に示すような先端先細り形状を有する回転摺接体３５であってもよい。すなわち、上述した回転摺接体４は、図８（ａ）に示すように、単純な円錐台であり、その断面や側面から投影した形状において、摺接面５は、直線Ｙ１とされている。これに対して図８（ｂ）に示す回転摺接体３４は、円錐台の摺接面が膨らんだ形状とされ、その断面や側面から投影した形状において、摺接面３５は、直線Ｙ１に対して外側に膨らんだ曲線Ｙ２とされている。円錐形状を外側に向けて膨らませた形状とされた摺接面３５を有する回転摺接体３４は、上述した加工装置１等に用いられることで、図７で説明した加工装置３１と同様の効果を奏する。すなわち、回転摺接体３４は、上下に取り付けられ先細り方向が異なるように対向配置されたときに、線材の走行方向から投影したときに重なる領域を有する。 Moreover, the rotary sliding contact body which comprises the processing apparatuses 1 and 31 mentioned above is not restricted to the rotary sliding contact body 4 demonstrated using FIGS. 1-7 mentioned above, For example, FIG.8 (b). A rotating sliding contact body 35 having a tapered tip shape as shown in FIG. That is, as shown in FIG. 8A, the rotary sliding contact body 4 described above is a simple truncated cone, and the sliding contact surface 5 is a straight line Y1 in the shape projected from the cross section and the side surface. . On the other hand, the rotary sliding contact body 34 shown in FIG. 8B has a shape in which the sliding contact surface of the frustum swells. On the other hand, the curve Y2 swells outward. The rotary sliding contact body 34 having the sliding contact surface 35 in which the conical shape is expanded outward is used in the above-described processing apparatus 1 and the like, and thus has the same effect as the processing apparatus 31 described in FIG. Play. That is, the rotary sliding contact body 34 has a region that is overlapped when projected from the traveling direction of the wire when they are mounted on the top and bottom so as to face each other so that their tapering directions are different.
よって、図８（ｂ）に示す回転摺接体３４を用いた加工装置は、上述の加工装置１と同様の効果が得られるのに加えて、図７（ｃ）で説明したのと同様に、線材３の長さ方向において各回転摺接体に接触する部分が増加し、換言すると線材３が各回転摺接体に接触する時間が増加し、これにより、研削力が向上し、加工性能が向上する。 Therefore, the processing apparatus using the rotary sliding contact body 34 shown in FIG. 8B can obtain the same effect as the processing apparatus 1 described above, and in the same manner as described in FIG. In the length direction of the wire 3, the portion in contact with each rotating sliding contact body increases, in other words, the time for the wire 3 to contact each rotating sliding contact body increases, thereby improving the grinding force and processing performance. Will improve.
