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.

And) in a weight ratio of 30/70 to 90/10 and a cross-linking agent 1 to 9 PHR added thereto.
【００１７】 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 TPU / F-TPE weight ratio is 30/70 to 70/30, and the crosslinking agent is 3 to 7 PHR.
【００１８】 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。When the above weight ratio is out of the above range, the advantages of TPU and F-TPE cannot be utilized, and the defects are surfaced. 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.

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.

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乃至VII からなる銅合金が、上記特開昭６３−４３２３９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１６．１万回に対し、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１ １．９３万回と約２６０分の１以下、曲げ歪０．１８％の条件では、上記銅合金 線：６２００万回以上、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-mentioned compositions I to VII forming the flexible conductor is very flexible as described in JP-A-63-43239. It has excellent conductivity and is comparable to pure copper. For example, in the fatigue characteristics, under the condition that the bending strain is 0.306%, the breaking bending number of the copper alloy wire is about 161,000 times, while that of the pure copper wire is about 43,000 times and about 4 minutes. 1 and the bending strain of 0.22%, the copper alloy wire: 31.5 million times or more, the pure copper wire: about 113,000 times and about 1/260 or less, the bending strain of 0.18% Then, the copper alloy wire: 62 million times or more, the pure copper wire: about 218,000 times, which is about 1/280 or less.

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. Further, since water-crosslinkable ethylene propylene rubber is used for the sheath (outer sheath), the thinner resistance is dramatically improved while maintaining the flexibility and heat resistance.
