Description
【０００１】[0001]
本考案は、塗装ロボットを制御するためのケーブル、詳しくは、可撓性、耐熱 、耐屈曲、耐摩耗性を有し、近年、産業界で問題になっているロボットの暴走の 発生を抑え、更に塗装用ケーブルにおいて最も重要な耐シンナー特性を飛躍的に 向上させた塗装ロボット用ケーブルに関する。 The present invention is a cable for controlling a painting robot, more specifically, it has flexibility, heat resistance, bending resistance, and wear resistance, and in recent years has reduced the occurrence of robot runaway, which has become a problem in the industry. Furthermore, it relates to cables for painting robots that dramatically improve the thinner resistance, which is the most important in painting cables.
【０００２】[0002]
塗装ロボット用ケーブルには、少くとも可撓性、耐摩耗性、耐屈曲性とロボッ トの暴走原因除去のための遮蔽特性、更に塗料の溶剤として使用されるシンナー に耐え得る特性を持っている必要がある。また、高温環境下で使用される場合は 、前記特性に加えて耐熱性が要求される。 Cables for painting robots have at least flexibility, wear resistance, bending resistance, shielding properties for eliminating the cause of robot runaway, and the ability to withstand thinner used as a paint solvent. There is a need. When used in a high temperature environment, heat resistance is required in addition to the above characteristics.
【０００３】 上記要求の特性を持つために、これまでの塗装ロボット用ケーブルは、可撓導 体上に、ポリテトラフルオロエチレン（ＰＴＦＥ）の絶縁被覆を設けて絶縁心線 とし、これを２本撚合わせ、その上に、押え巻きテープ、軟銅細線の編組および 押え巻きテープを順々に施して遮蔽心線を作り、その遮蔽心線を必要本数、介在 と共に撚合わせ、その上に押え巻きテーピングを施してケーブル芯とし、その上 にポリウレタンエラストマーを主材とする樹脂組成物で外被を設けたものがある 。In order to have the above-mentioned required characteristics, the conventional coating robot cables have an insulating coating of polytetrafluoroethylene (PTFE) provided on the flexible conductor to form an insulating core wire. Twisting, and then a press-winding tape, a braid of annealed copper wire and a press-winding tape are applied in order to create a shielded core wire, and the shielded core wire is twisted together with the required number and interposers, and then the press-winding tape is applied. In some cases, a cable core is formed by applying a coating, and a resin composition containing a polyurethane elastomer as a main material is coated on the core.
【０００４】 ここで、外被としてＰＴＦＥを採用すると、耐シンナー特性は十分であるが、 反面、加工性及びケーブルの可撓性が損なわれる。このため、外被の押出成形が 困難となるうえに、スプレーガンの作動がスムーズでなくなるため、耐シンナー 特性を犠牲にして、従来では、前記のごとくポリウレタンエラストマーなどが使 用されている。しかし、このポリウレタンエラストマーは耐シンナー特性が悪く 、常温のシンナー中に１０日間浸せきすると膨潤する。即ち、塗装ロボット用と して長期間使用すると、膨潤状態になる。膨潤すると、繰り返し屈曲により外被 が破れる。When PTFE is used as the jacket, the thinner resistance is sufficient, but the workability and the flexibility of the cable are impaired. For this reason, extrusion molding of the jacket becomes difficult, and the spray gun does not operate smoothly. Therefore, at the expense of thinner resistance, polyurethane elastomers and the like have been conventionally used as described above. However, this polyurethane elastomer has poor thinner resistance and swells when immersed in thinner at room temperature for 10 days. That is, if it is used for a coating robot for a long period of time, it will swell. When swelled, the jacket is torn by repeated bending.
【０００５】 また、絶縁心線の可撓性は、その導体を細線の多数本集合撚りとすることによ って得られるが、今日、より高い可撓性が望まれており、ＰＴＦＥは前述のよう に可撓性が悪いため、その絶縁被覆としては問題がある。さらに、銅（Ｃｕ）単 独の可撓純銅撚線では耐屈曲性が十分満足できるものは得られておらず、より高 い耐屈曲性が望まれている。Further, the flexibility of the insulating core wire can be obtained by twisting the conductor into a large number of fine wires, but today, higher flexibility is desired, and PTFE has been described above. As described above, it has a problem as an insulating coating due to its poor flexibility. Further, a flexible pure copper stranded wire made of only copper (Cu) has not been sufficiently satisfactory in flex resistance, and higher flex resistance is desired.
【０００６】 本考案は、上記の状況に鑑み、主課題として、耐シンナー特性を飛躍的に向上 させることであり、副課題は可撓性及び耐屈曲性を改良することにある。In view of the above situation, the present invention is to dramatically improve the thinner resistance property as a main problem, and the secondary problem is to improve flexibility and bending resistance.
【０００７】[0007]
上記の課題を解決するために、本考案にあっては、可撓導体を下記の銅合金（ Ｉ）に記載のものとし、その可撓導体に下記樹脂組成物ａの絶縁被覆を施した複 数本の絶縁心線を撚合わせ、その周りに遮蔽層を設けて、さらにその上に押え巻 きテープ層を形成して遮蔽心線とし、この遮蔽心線を複数本撚合わせ、その周り に熱可塑性ポリエステルエラストマーを主体とする樹脂組成物により外被を設け てなる構成としたのである。上記遮蔽心線は介在とともに撚合わせるとよい。 In order to solve the above problems, in the present invention, the flexible conductor is described in the following copper alloy (I), and the flexible conductor is coated with an insulating coating of the following resin composition a. Several insulated core wires are twisted together, a shielding layer is provided around it, and a winding tape layer is formed on top of that to form a shielded core wire. The outer cover is made of a resin composition mainly composed of a thermoplastic polyester elastomer. The shielding core wire may be twisted together with the interposition.

Furthermore, the O 2 content of the copper alloy is preferably less than 50 ppm, and the recrystallization structure of the composition metal is preferably 50% or less.

【００１１】 〔樹脂組成物ａ〕 ポリエーテルまたはポリカーボネート系ポリウレタンエラストマー（以下、Ｔ ＰＵという。）と、ポリ弗化ビニリデン（以下、ＰＶＤＦという。）をベースと する弗素系エラストマー（以下、Ｆ−ＴＰＥという。）と、を重量比で３０／７ ０〜９０／１０の範囲で混練りし、これに架橋剤１〜９ＰＨＲを添加した樹脂組 成物。[Resin Composition a] A fluorine-based elastomer (hereinafter, F-TPE) based on a polyether or polycarbonate polyurethane elastomer (hereinafter, TPU) and polyvinylidene fluoride (hereinafter, PVDF). And) in a weight ratio of 30/70 to 90/10 and a cross-linking agent 1 to 9 PHR added thereto.
【００１２】 好ましくは、上記ＴＰＵ／Ｆ−ＴＰＥの重量比は３０／７０〜７０／３０とす るとよく、また、上記架橋剤は３〜７ＰＨＲを添加するとよい。Preferably, the weight ratio of TPU / F-TPE is 30/70 to 70/30, and 3 to 7 PHR is added to the crosslinking agent.
【００１３】 上記重量比が上記の範囲を外れると、ＴＰＵ、Ｆ−ＴＰＥの長所を生かすこと ができず欠点が表面化する。即ち、ＴＰＵが多くなると、耐熱性、耐水性、電気 絶縁性が悪くなる。またＦ−ＴＰＥが多くなると、押出加工性、機械特性が悪く なる。一方、ＴＰＵが少ないときは耐摩耗性、引張強度および広い温度範囲での 弾性が期待できなくなる。Ｆ−ＴＰＥが少ないときは、耐熱性、耐薬品性、表面 の滑り性が期待できなくなる。If the weight ratio is out of the above range, the advantages of TPU and F-TPE cannot be utilized, and the defects are exposed. That is, when TPU is increased, heat resistance, water resistance, and electric insulation are deteriorated. Further, when the amount of F-TPE is large, extrusion processability and mechanical properties deteriorate. On the other hand, when TPU is low, wear resistance, tensile strength and elasticity in a wide temperature range cannot be expected. When F-TPE is low, heat resistance, chemical resistance, and surface slipperiness cannot be expected.
【００１４】 上記架橋剤が上記範囲より少ないときは、引張強度、硬度、加熱変形耐力、伸 び等、所望の物理特性を得ることができない。また逆に、架橋剤が多いときは過 架橋となり、硬度が高くなって、耐熱老化性、柔軟性が低下し、架橋剤がブルー ミングして外観が悪くなる。When the amount of the cross-linking agent is less than the above range, desired physical properties such as tensile strength, hardness, heat deformation resistance and elongation cannot be obtained. On the contrary, when the amount of the cross-linking agent is large, the cross-linking agent is over-crosslinked, the hardness is increased, the heat aging resistance and the flexibility are lowered, and the cross-linking agent is bloomed to deteriorate the appearance.
【００１５】 上記ＴＰＵとしては表１に示すものを、Ｆ−ＴＰＥとしては表２に示すものを 挙げることができる。As the TPU, those shown in Table 1 can be mentioned, and as the F-TPE, those shown in Table 2 can be mentioned.

H.S = 7: 3 for Perprene (registered trademark) P-150B (JISA hardness: 98) manufactured by Co., Ltd. As a result of the thinner resistance test, the grades of P-70B and P-55B were also usable.

【作用】 上記の如く構成する本考案に係るケーブルは、まず、可撓導体をなす上記組成 Ｉからなる銅合金が、上記特公昭６２−５６２１７号公報等に記載のごとく、耐 屈曲性に優れ、導電性においても、純銅に比べて遜色がない。例えば、疲労特性 において、曲げ歪０．３０６％の条件では、上記銅合金線の破断屈曲回数が約１ ６．１万回に対し、純銅線のそれは約４．３万回と約４分の１であり、曲げ歪０ ．２２％の条件では、上記銅合金線：３１５０万回以上、純銅線：約１１．９３ 万回と約２６０分の１以下、曲げ歪０．１８％の条件では、上記銅合金線：６２ ００万回以上、純銅線：約２１．８万回と約２８０分の１以下である。In the cable according to the present invention configured as described above, first, the copper alloy having the above composition I forming the flexible conductor is excellent in bending resistance as described in Japanese Patent Publication No. 62-56217. Also in terms of conductivity, it is comparable to pure copper. For example, in the fatigue characteristics, under the condition that the bending strain is 0.306%, the number of bending and breaking of the copper alloy wire is about 161,000 times, whereas that of the pure copper wire is about 43,000 times and about 4 minutes. 1 and bending strain 0. Under the condition of 22%, the above-mentioned copper alloy wire: 31.5 million times or more, pure copper wire: about 1193,000 times, about 1/2/260 or less, and under the condition of bending strain 0.18%, the above-mentioned copper alloy wire: 6200. 10,000 times or more, pure copper wire: about 218,000 times, which is less than 1/280.
【００２０】 また、その絶縁心線が、ＴＰＵ部分で耐摩耗性を保ち、Ｆ−ＴＰＥ部分で耐屈 曲性及び耐熱性を保ち、上記特定の配合範囲で、耐熱、耐屈曲、耐摩耗性の特性 を保持する。このため、ケーブル全体としてもそれらの特性を有する。また、樹 脂組成物ａの絶縁被覆は滑り性がよいため、絶縁心線相互の滑り性もよい。この ため、ケーブル全体の可撓性もよい。さらに、シース（外被）に熱可塑性ポリエ ステルエラストマーを採用しているため、前記可撓性、耐熱性等を保ちながら、 耐シンナー性が飛躍的に向上する。In addition, the insulating core wire maintains wear resistance in the TPU portion, and flex resistance and heat resistance in the F-TPE portion. Within the above specific compounding range, heat resistance, bending resistance, and wear resistance are maintained. Retain the characteristics of. Therefore, the cable as a whole has these characteristics. Further, since the insulating coating of the resin composition a has a good slip property, the insulating core wires also have a good slip property. Therefore, the flexibility of the entire cable is good. Furthermore, since the thermoplastic polyester elastomer is used for the sheath (outer sheath), the thinner resistance is dramatically improved while maintaining the flexibility and heat resistance.
