Description

この発明は、例えば樹脂被覆ロープを構成する線材の表面処理装置に関し、一直線上に張設されつつその長手方向に走行する線材の外周に硬質微粒子を噴射して線材の外周面を均一に表面処理する線材の表面処理装置に関するものである。   The present invention relates to a surface treatment apparatus for a wire constituting, for example, a resin-coated rope, and uniformly treats the outer peripheral surface of the wire by injecting hard fine particles onto the outer periphery of the wire running in the longitudinal direction while being stretched in a straight line. The present invention relates to a wire surface treatment apparatus.

数本の鋼製素線を撚り合せたストランドをさらに撚り合せた鋼線ロープに樹脂を被覆する際、鋼線ロープに接着剤を塗布し、樹脂を接着固定することが多い。
この場合、鋼線ロープ表面、即ち線材の表面に汚染物質などの付着があると、接着剤との濡れが悪く、接着強度の低下や強度のばらつきを生じる。そこで、このような線材表面の汚染物質を除去するものとして、細かい粒体からなる研削材を圧縮空気と共に線材表面に噴射して線材の表面を加工する装置が知られている。（例えば、特許文献１参照。）
また、線材を供給する線材供給部と、走行する線材に対して投射材を投射する投射部と、投射材が投射された線材を巻き取る巻き取り部とを有するショット装置において、線材の走行時の姿勢を安定させ、線材の全周を均一に処理するために、線材の振れを防止する振れ防止手段（あるいは揺れ防止手段）を設けるものが、例えば、特許文献２（あるいは特許文献１）に開示されている。 When a resin is coated on a steel wire rope obtained by further twisting a strand obtained by twisting several strands of steel, an adhesive is applied to the steel wire rope and the resin is often bonded and fixed.
In this case, if contaminants or the like adhere to the surface of the steel wire rope, that is, the surface of the wire, wetting with the adhesive is poor, resulting in a decrease in adhesive strength and variations in strength. Therefore, as a means for removing such contaminants on the surface of the wire, an apparatus for processing the surface of the wire by injecting a grinding material made of fine particles onto the surface of the wire together with compressed air is known. (For example, refer to Patent Document 1.)
Further, in a shot device having a wire rod supply unit that supplies a wire rod, a projection unit that projects a projection material onto a traveling wire rod, and a winding unit that winds up the wire rod onto which the projection material is projected, For example, Patent Document 2 (or Patent Document 1) is provided with a shake preventing means (or a shake preventing means) for preventing the shake of the wire in order to stabilize the posture of the wire and process the entire circumference of the wire uniformly. It is disclosed.

しかしながら、上記特許文献１に示される揺れ防止手段は、線材への研削材の噴射位置の搬送方向上流側と下流側とに離間して、単に、上下一対づつのガイドローラとテンションローラによって揺れ防止手段を構成したもので、ノズルからの研削材の噴射に対し、揺れ抑制効果が十分とはいえず、また、揺れ防止手段を交換する際に、線材を張ったままでの交換は出来ず、揺れ防止手段の交換作業が煩雑である。   However, the swing prevention means disclosed in Patent Document 1 is separated from the upstream side and the downstream side in the conveying direction of the injection position of the abrasive to the wire, and is simply prevented by a pair of upper and lower guide rollers and a tension roller. This means that the effect of suppressing shaking is not sufficient for jetting abrasives from the nozzle, and when exchanging anti-swing means, it is not possible to replace the wire while it is stretched. The replacement work of the prevention means is complicated.

また、特許文献２に示される振れ止め防止手段は、投射装置が形成する投射材の投射領域をガイドするガイドパイプによって投射材の投射による線材の振れを防止するようにしたものである。このガイドパイプが金属製パイプにゴムや樹脂等の弾性体を挿着した構造のものであるため、投射材の投射を受けて発熱した線材の熱によりブッシュが早期に磨耗
したり、焼損したりし、しかも線材とブッシュとの間に投射材が進入してガイドパイプ内が詰まったりし、その結果、線材に傷が付くなどの問題がある。
また、振れ防止手段を交換する際に、線材を張ったままでの交換は出来ず、交換作業が煩雑になるという上記特許文献１と同様の問題がある。 Further, the steady-state prevention means disclosed in Patent Document 2 prevents the deflection of the wire due to the projection of the projection material by the guide pipe that guides the projection area of the projection material formed by the projection device. Since this guide pipe has a structure in which an elastic body such as rubber or resin is inserted into a metal pipe, the bushing is quickly worn or burned out by the heat of the wire generated by the projection of the projection material. In addition, the projection material enters between the wire and the bush and the guide pipe is clogged. As a result, there is a problem that the wire is damaged.
Further, when exchanging the shake preventing means, there is a problem similar to the above-mentioned Patent Document 1 in which the replacement with the wire rod cannot be performed and the replacement work becomes complicated.

この発明は、上記のような従来装置の問題点を解消するためになされたもので、線材の揺れを抑制して全周面でむらなく均一な処理ができ、ひいては鋼線ロープに被覆した樹脂との接着強度が高く、強度のばらつきが少ない鋼線ロープを得る事のできる線材の表面処理装置を提供することを目的とする。
また、簡単な構成で、線材を張ったままで交換ができる線材の揺れ抑制手段を備えた作業性に優れた線材の表面処理装置を提供することを目的とする。 The present invention was made to solve the problems of the conventional apparatus as described above, and can be uniformly processed on the entire circumferential surface by suppressing the shaking of the wire, and as a result, a resin coated on a steel wire rope It is an object of the present invention to provide a wire surface treatment apparatus that can obtain a steel wire rope having a high adhesive strength and a small variation in strength.
It is another object of the present invention to provide a surface treatment apparatus for a wire that has a simple configuration and is excellent in workability, and includes a wire sway suppressing means that can be replaced while the wire is stretched.

この発明に係わる線材の表面処理装置は、一直線状に張設されつつ、その長手方向に移動する線材の外周に硬質微粒子を噴射して、その外表面を処理するブラスト装置を備えた線材の表面処理装置において、前記ブラスト装置は、線材の軸線の回りに周方向に等間隔で放射状に配置され、互いに対向しないように線材の軸線方向に互いに離間して配置された複数のノズルと、前記各ノズルの噴射側に配置され、線材が嵌まる溝を有する２個で一組の取り外し可能な溝付背板からなる線材の揺れ抑制手段を備えたものである。   A surface treatment apparatus for a wire according to the present invention is a surface of a wire provided with a blasting device for injecting hard fine particles onto the outer periphery of a wire moving in the longitudinal direction while being stretched in a straight line, and treating the outer surface of the wire In the processing apparatus, the blasting device is arranged radially at equal intervals around the axis of the wire, and is spaced apart from each other in the axial direction of the wire so as not to face each other. It is provided on the jet side of the nozzle and is provided with wire rod sway suppression means comprising a pair of removable grooved back plates having grooves into which the wire is fitted.

この発明の線材の表面処理装置によれば、線材の全周面でむらなく均一な処理ができ、ひいては鋼線ロープに被覆した樹脂との接着強度が高く、強度のばらつきが少ない鋼線ロープの製作が可能な線材の表面処理装置を得ることができる。
また、揺れ抑制手段は簡単な構成で、線材を張ったままで交換ができるので、安価で作業性に優れた線材の表面処理装置を得ることができる。 According to the surface treatment apparatus for a wire rod according to the present invention, a uniform treatment can be performed uniformly on the entire circumferential surface of the wire rod, and as a result, the adhesive strength with the resin coated on the steel wire rope is high, and there is little variation in strength. A surface treatment apparatus for a wire that can be manufactured can be obtained.
In addition, since the vibration suppressing means has a simple configuration and can be replaced while the wire is stretched, it is possible to obtain a wire surface treatment apparatus that is inexpensive and excellent in workability.

A surface treatment apparatus for a wire according to Embodiment 1 of the present invention will be described in detail with reference to FIGS. 1 is a schematic configuration diagram of a blasting apparatus according to the first embodiment, FIG. 2 is a schematic diagram illustrating a configuration of a shaking suppression unit, and FIG. 3 illustrates an arrangement relationship between a nozzle and the shaking suppression unit viewed from the side of FIG. FIG. 4 is an enlarged view of a part A in FIG. 3, FIG. 5 is a schematic diagram of a solvent ultrasonic cleaning device and a drying furnace, and FIG. 6 is a schematic diagram of a primer coating device and a drying furnace. In addition, in each figure, the same code | symbol shall show the same or an equivalent part. Further, in Embodiment 1 of the present invention, the steel wire as the wire means a cross-sectional shape of a circle, a substantially circular shape, a corner, a deformed single wire, a long product obtained by twisting these single wires, and the material is The hardness of steel, light alloy, composite material, etc. does not matter.

図１〜図６において、線材の表面処理装置の一連の連続処理ラインは、図５に示す溶剤の超音波洗浄装置１２、熱風乾燥炉１３と、図１に示すブラスト装置１と、図６に示すプライマ塗布装置１４、熱風乾燥炉１５が順に直線配置されている。なお、ここでは、線材の巻出し装置と巻取り装置は記載を省略している。
ロープグリスを含浸せず伸線潤滑剤のみで加工した数本の鋼製素線を撚り合せた直径１．３ｍｍのストランド１１を、ＩＰＡ（イソプロピルアルコール）もしくはＭＥＫ（メチルエチルケトン）とトルエンの混合液で満たした超音波洗浄装置１２に通して、加工潤滑剤を除去し、熱風乾燥炉１３にて乾燥する。ストランド１１に水分や異物が付着していると、次工程のブラスト処理で砥粒が装置内で凝固してノズルの目詰まりが発生する恐れがあるため、熱風乾燥炉１３での乾燥時間は十分に取る必要がある。 1 to 6, a series of continuous treatment lines of the wire surface treatment apparatus include an ultrasonic cleaning apparatus 12 for a solvent, a hot air drying furnace 13 illustrated in FIG. 5, a blast apparatus 1 illustrated in FIG. A primer coating device 14 and a hot air drying furnace 15 shown in FIG. Here, description of the wire unwinding device and the winding device is omitted.
A strand 11 having a diameter of 1.3 mm obtained by twisting several steel strands not impregnated with rope grease and processed only with a wire drawing lubricant is mixed with a mixed solution of IPA (isopropyl alcohol) or MEK (methyl ethyl ketone) and toluene. The processed lubricant is removed by passing through the filled ultrasonic cleaning device 12 and dried in a hot air drying furnace 13. If moisture or foreign matter adheres to the strand 11, the abrasive grains may solidify in the apparatus by the blasting process in the next process and the nozzle may be clogged. Therefore, the drying time in the hot air drying furnace 13 is sufficient. Need to take on.

乾燥後、９０°毎にストランド１１の断面中心に向けて配置した４本のノズル４、５、６、７と、各ノズルの対向する位置に２個で一組の半径２ｍｍで、深さが２ｍｍの半円状の溝３を有する溝付背板２からなる揺れ抑制手段を備えたブラスト装置１に通して、ストランド１１の全周面の酸化膜除去と粗化をする。揺れ抑制手段は図２に示すように、一組の溝付背板２をブラスト装置１内に設けた支柱１６にねじ止め（図示せず）することによって着脱自在に固定して構成され、支柱１６には、ノズル４から噴射される砥粒１７が当たることによる破損から保護するために、溝付背板２間の支柱にゴム製のカバー８が被覆されている。   After drying, there are four nozzles 4, 5, 6, 7 arranged toward the center of the cross section of the strand 11 every 90 °, and two nozzles at a position opposite to each nozzle, with a set radius of 2 mm and depth. The oxide film is removed and roughened on the entire peripheral surface of the strand 11 through a blasting device 1 provided with shaking suppression means composed of a grooved back plate 2 having a 2 mm semicircular groove 3. As shown in FIG. 2, the vibration suppressing means is configured to be fixed detachably by screwing (not shown) a set of grooved back plate 2 to a column 16 provided in the blast device 1. 16 is covered with a rubber cover 8 on the struts between the grooved back plates 2 in order to protect against damage caused by the abrasive grains 17 sprayed from the nozzle 4 being hit.

なお、溝付背板２の材質としては、アルミナセラミックもしくはＤＬＣ（ダイヤモンドライクカーボン）処理または窒化処理した鋼材が適当であり、カバー８には、シェアＡ硬度５０以下のウレタンゴムが適当である。
また、溝付背板の溝形状は、半円で、溝幅Ｗ（直径）が線形より０．５〜１ｍｍ大きく、溝の深さＤが線径の１〜１．５倍であることが望ましい。
また、ストランド線径は直径２ｍｍ以下が望ましく、エアブラスト処理は、＃１８０以上の粒径が小さい尖形状部を有する微粉アルミナ系砥粒を使用することが望ましい。 As the material for the grooved back plate 2, alumina ceramic or DLC (diamond-like carbon) -treated or nitrided steel is suitable, and the cover 8 is suitably urethane rubber having a shear A hardness of 50 or less.
Further, the groove shape of the grooved back plate is a semicircle, the groove width W (diameter) is 0.5 to 1 mm larger than the linear shape, and the groove depth D is 1 to 1.5 times the wire diameter. desirable.
The strand wire diameter is desirably 2 mm or less, and the air blast treatment desirably uses finely divided alumina-based abrasive grains having a pointed portion having a small particle diameter of # 180 or more.

ストランド１１はブラスト装置を通ってブラスト処理される際に、溝付背板２の溝３に嵌められることによって横振動の動きが拘束され、またブラスト装置１の前側に備えられたカウンタウエイト１０によってストランド１１の弛みが防止されることと相俟って、ストランド１１の揺れが確実に抑制される。これによってストランド１１の全周面でムラなく均一な表面処理ができる。
また、溝付背板２もブラスト処理され磨耗するため、度合を見て交換する必要があるが、
ストランド１１を溝３に嵌める構造なので、ストランドを張ったままで溝付背板２の交換が容易にでき、装置の作業性を向上させることができる。 When the strand 11 is blasted through the blasting device, the movement of the lateral vibration is restricted by being fitted into the groove 3 of the grooved back plate 2, and the counterweight 10 provided on the front side of the blasting device 1 is used. Coupled with the prevention of the slack of the strand 11, the swing of the strand 11 is reliably suppressed. As a result, a uniform surface treatment can be performed on the entire circumferential surface of the strand 11 without unevenness.
In addition, since the grooved back plate 2 is also blasted and worn out, it is necessary to replace it by looking at the degree.
Since the structure is such that the strand 11 is fitted in the groove 3, the grooved back plate 2 can be easily replaced while the strand is stretched, and the workability of the apparatus can be improved.

ブラスト処理後、エアブラストの処理室に浮遊する微小なホコリがストランド表面に付着していると、次工程のプライマ塗布で支障をきたす恐れがあるので、ブラスト装置１の出口に設けた筒状の風箱（エアワイパ）９で表面の付着物を吹き飛ばす。
ブラスト処理後のストランド表面は活性で化学反応が起きやすく、放置すると空気と反応して酸化が進む。これを抑制し、ストランド即ち線材と接着剤との濡れ性（wetting）をよくするため、ブラスト処理後すぐにプライマ塗布装置１４のプライマ液漕にストランド１１を通し、熱風乾燥炉１５で乾燥して、プライマの膜を作る。 After the blasting process, if fine dust floating in the air blasting chamber adheres to the strand surface, there is a risk that the primer application in the next process may be hindered. A surface box (air wiper) 9 blows away deposits on the surface.
The strand surface after blasting is active and easily undergoes a chemical reaction, and if left untreated, it reacts with air and oxidizes. In order to suppress this and improve the wetting between the strand, that is, the wire and the adhesive, immediately after the blasting process, the strand 11 is passed through the primer liquid tank of the primer coating device 14 and dried in the hot air drying furnace 15. Make a primer film.

以上のように、この発明の実施の形態１の線材の表面処理装置によれば、ストランドを鋼線ロープへと撚り合わす前に、ストランド1本1本を洗浄し、酸化膜除去し、表面粗化（ブラスト処理）し、プライマ塗布するに際し、ブラスト装置内に、線材の軸線の回りに周方向に等間隔で放射状に配置され、互いに対向しないように線材の軸線方向に互いに離間して配置された複数のノズルと、前記各ノズルの噴射側に配置され、線材が嵌まる溝を有する２個で一組の取り外し可能な溝付背板からなる線材の揺れ抑制手段を備えたので、
ブラスト処理時に線材の揺れが確実に抑制され、線材の全周面でむらなく均一な処理ができる。従って、鋼線ロープに被覆した樹脂との接着強度が高く、強度のばらつきが少ない鋼線ロープの製作が可能となる。
また、揺れ抑制手段は、簡単な構成で、線材を張ったままで交換ができるので、安価で作業性に優れた線材の表面処理装置を得ることができる。 As described above, according to the surface treatment apparatus for wire according to the first embodiment of the present invention, before twisting the strands into the steel wire rope, each strand is washed, the oxide film is removed, and the surface roughening is performed. When blasting and applying primer, they are arranged in the blasting device radially at equal intervals around the axis of the wire, and spaced apart from each other in the axial direction of the wire so as not to face each other. Since it has a plurality of nozzles, and two wire rods that are arranged on the injection side of each nozzle and have a groove in which the wire is fitted, a pair of removable grooved back plates,
The swaying of the wire is surely suppressed during the blasting process, and uniform processing can be performed uniformly on the entire peripheral surface of the wire. Therefore, it is possible to produce a steel wire rope having high adhesive strength with the resin coated on the steel wire rope and little variation in strength.
In addition, since the vibration suppression means can be replaced with a simple configuration while the wire is stretched, a surface treatment apparatus for the wire that is inexpensive and excellent in workability can be obtained.
