본 발명은 이단 피복 로프에 관한 것으로서, 더욱 상세하게는 연속적으로 이단의 피복작업이 이루어져 제조작업이 일원화되고 신축성과 강도가 우수한 이단 피복 로프 및 그 제조방법에 관한 것이다.The present invention relates to a two-stage coated rope, and more particularly, to a two-stage coated rope in a continuous two-stage coating operation to unify the manufacturing work and excellent elasticity and strength, and a manufacturing method thereof.

일반적으로 로프는 산악등반, 인명구조 내지 레조용 등으로 사용되는 것으로, 내측에는 주로 강선이나 고무 다발이 트위스팅되어 심선을 이루고 심선 외면에 섬유재 외피가 피복된다.In general, the rope is used for mountain climbing, life-saving or resor, etc., the inner side is mainly twisted steel wire or rubber bundle to form a core wire and the outer surface of the core is coated with a fiber shell.

그런데, 이러한 로프는 통상 소선 꼬임 장치를 이용하여 심선 외면에 외피를 한겹만 피복하게 되기 때문에 충분한 강도를 확보하기가 어렵고 내구성도 저하되는 문제점이 있다.However, such a rope usually has a problem in that it is difficult to secure sufficient strength and durability is reduced because only one layer of the outer skin is coated on the outer surface of the core wire using a wire twisting device.

따라서, 외피가 한겹 피복된 로프를 다시 소선 꼬임 장치에 넣어서 이단으로 제조할 수도 있겠으나, 이 경우 제조과정이 번거롭고 특히 번지점프와 같은 레저용으로 활용될 때에 신축성이 우수하면서도 피부 등에 접촉시 화상의 우려가 작은 로프의 제조가 필요하다.Therefore, it is possible to manufacture a two-stage coated rope with the outer layer of the rope again in the wire twisting device, but in this case, the manufacturing process is cumbersome, and especially when used for leisure purposes such as bungee jumping, it has excellent elasticity, There is a need for the manufacture of small ropes of concern.

본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 심선 외면에 이단의 피복을 연속적으로 입혀서 제조과정이 신속하고 번지점프용으로 사용되는 경우에도 충분한 신축성과 강도가 확보되며 화상의 우려가 작은 이단 피복 로프 및 그 제조방법을 제공하는데 그 목적이 있다.The present invention has been made in order to solve the problems of the prior art as described above, by applying a two-stage coating on the outer surface of the core wire continuously, even if the manufacturing process is used for fast and bungee jumping is secure enough elasticity and strength of the image It is an object of the present invention to provide a double-coated rope having a low concern and a method of manufacturing the same.

이와 같은 목적을 달성하기 위한 본 발명의 이단 피복 로프는 다수 개의 심선이 꼬이지 않은 상태로 배치되는 심선부; 상기 심선부의 외면을 제1 소선으로 경사지게 꼬아서 고정하는 내피부; 및 상기 내피부의 외면을 제2 소선으로 교차되게 꼬아서 고정하는 외피부를 포함하여 구성되는 것을 특징으로 한다.The two-stage coated rope of the present invention for achieving the above object is the core portion which is arranged in a state that the plurality of core wires are not twisted; An inner skin for twisting and fixing the outer surface of the core portion inclined with a first element wire; And an outer skin that twists and fixes the outer surface of the inner skin to cross the second element wire.

또한, 본 발명의 이단 피복 로프 제조방법은 다수 개의 심선을 중앙에서 모아 수직으로 이송하면서 외면을 제1 소선으로 경사지게 꼬아서 고정하는 내피부 형성 단계; 및 상기 제1 소선이 피복된 심선을 계속해서 수직으로 이송하면서 외면을 제2 소선으로 교차되게 꼬아서 고정하는 외피부 형성 단계를 포함하여 구성되는 것을 특징으로 한다.In addition, the method of manufacturing a two-stage coated rope of the present invention comprises the step of forming the inner skin to collect a plurality of core wires in the center to transfer vertically by twisting the outer surface inclined to the first element wire; And an outer skin forming step of twisting and fixing the outer surface to cross the second element wire while continuously transporting the core wire coated with the first element wire vertically.

여기서, 상기 내피부 형성 단계는 다수 개의 심선을 양측에서 대칭으로 이송시켜 중앙에서 모으고, 상기 외피 형성 단계를 거쳐 제1,2 소선이 피복된 심선은 전체 두께에 맞추어 롤러 사이의 간격을 조절하면서 눌러 이송하는 것을 특징으로 한다.Here, in the inner skin forming step, a plurality of core wires are symmetrically transferred from both sides to be collected at the center, and the core wires coated with the first and second element wires are press-feeded while adjusting the gap between the rollers according to the overall thickness through the outer skin forming step. Characterized in that.

이와 같이 구성된 본 발명의 이단 피복 로프 및 그 제조방법은 이단피복 제조과정이 연속적이어서 다량생산이 가능하고 신축성과 강도가 유지되며 화상의 우려가 작은 유용한 효과를 발휘한다.The two-stage coated rope and the manufacturing method of the present invention configured as described above have a useful effect because the two-stage coating manufacturing process is continuous, thus allowing a large amount of production, maintaining elasticity and strength, and reducing the risk of burns.

이하, 본 발명의 목적이 구체적으로 실현될 수 있는 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다. 본 실시예를 설명함에 있어서, 동일 구성에 대해서는 동일 명칭 및 동일 부호가 사용되며 이에 따른 부가적인 설명은 생략하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of this embodiment, the same name and the same reference numerals are used for the same configuration and additional description thereof will be omitted.

도 1은 본 발명에 따른 이단 피복 로프를 나타내는 사시도 및 일부 확대 단면도이다.1 is a perspective view and a partially enlarged cross-sectional view showing a two-stage coated rope according to the present invention.

본 발명의 이단 피복 로프는 심선부(10), 내피부(20) 및 외피부(30)를 포함하여 구성된다.The double-coated rope of the present invention includes a core wire portion 10, an inner skin portion 20, and an outer skin portion 30.

심선부(10)는 다수 개의 심선(11) 다발이 꼬이지 않은 상태로 배치되며, 상기 심선(11) 다발의 재질은 신축성이 우수한 고무를 사용하는 것이 바람직하다.The core portion 10 is disposed in a state where the plurality of core wires 11 are not twisted, and the core wire 11 is preferably made of rubber having excellent elasticity.

내피부(20)는 상기 심선부(10)의 심선(11) 다발 외주면을 소선 꼬임 장치(도면에 미도시)를 이용하여 제1 소선(21)으로 심선(11) 다발의 방향과 경사지게 꼬아서 고정하며, 상기 제1 소선(21)은 강도 내지 인성이 우수한 나일론 재질을 사용하는 것이 바람직하다.The inner skin 20 is fixed by twisting the outer circumferential surface of the bundle 11 of the core wire part 10 in an inclined direction and the direction of the bundle of the core wire 11 to the first element wire 21 using a wire twisting device (not shown). In addition, the first element wire 21 is preferably made of a nylon material excellent in strength or toughness.

구체적으로, 상기 내피부(20)를 형성하는 단계는 다수 개의 심선(11)을 중앙 에서 모아 수직으로 이송하면서 외면에 상기 제1 소선(21)을 감게 되는데, 이것은 일방향에서 심선(11)을 공급받아 제1 소선(21)을 감는 경우에 완성된 로프가 비틀어지는 것을 방지하기 위함이다.Specifically, in the forming of the inner skin 20, a plurality of core wires 11 are collected from the center and transported vertically to wind the first element wire 21 on the outer surface, which is supplied with the core wires 11 in one direction. This is to prevent the completed rope from twisting when the first element wire 21 is wound.

이를 위하여 소선 꼬임 장치에 심선(11) 다발을 공급할 때 양측에 이송 롤러(도면에 미도시)를 대칭으로 각각 설치하고, 이송 롤러로부터 공급된 다수 개의 심선(11)을 중앙에서 다발로 모은 다음에 제1 소선(21)을 감도록 구성한다.To this end, when feeding the bundle of core wires 11 to the strand twisting device, a feeding roller (not shown in the drawing) is symmetrically installed on both sides, and a plurality of core wires 11 supplied from the feeding rollers are collected in a bundle at the center. It is comprised so that the 1st element wire 21 may be wound.

상기 소선 꼬임 장치는 일반적으로 이송되는 심선 주위에 배치된 여러 개의 소선 보빈이 지그재그로 이동하면서 심선에 소선을 감게 되는 장치로 당업자에게는 그 구성이 자명하므로 자세한 설명은 생략한다.The strand twisting device is a device in which a plurality of strand bobbins disposed around a core wire to be transported are generally wound around the core wire while moving in a zigzag, and thus the detailed description thereof will be omitted.

외피부(30)는 상기 내피부(20)의 외주면을 내피부(20)와 마찬가지로 소선 꼬임 장치를 이용하여 제2 소선(31)으로 제1 소선(21)과 교차되게 꼬아서 고정하며, 상기 제2 소선(31)은 신체에 접촉할 때에 화상의 우려가 작도록 폴리에틸렌 재질을 사용하는 것이 바람직하다.The outer skin 30 twists and fixes the outer circumferential surface of the inner skin 20 so as to intersect the first wire 21 with the second wire 31 using the wire twisting device similarly to the inner skin 20. The element wire 31 is preferably made of polyethylene so as to reduce the risk of burns when it comes into contact with the body.

구체적으로, 상기 외피부(30)를 형성하는 단계는 상기 제1 소선(21)이 피복된 심선(11)을 계속해서 수직으로 이동하면서 외면을 제2 소선(31)으로 교차되게 꼬아서 고정하는데, 이때 제1 소선(21)의 방향과 교차되게 꼬아서 제1 소선(21) 상에서 제2 소선(31)이 미끄러지지 않고 촘촘하게 감아지는 것이다.Specifically, the forming of the outer skin part 30 is to twist and fix the outer surface to cross the second element wire 31 while continuously moving the core wire 11 covered with the first element wire 21 vertically. At this time, the second element 31 is wound tightly without slipping on the first element 21 by twisting to cross the direction of the first element 21.

즉, 본 발명의 이단 피복 로프는 여러 개의 소선보빈이 구비된 소선 꼬임 장치를 상하 수직 이단으로 배치하여 심선부(10)를 수직 이동시키면서 제1 소선(21)과 제2 소선(31)을 연속적으로 감게 된다.That is, the two-stage coated rope according to the present invention continuously arranges the first strand 21 and the second strand 31 while vertically moving the core 10 by disposing the strand twist device having a plurality of strand bobbins up and down vertically. It is wound up.

한편, 상기와 같이 외피부 형성 단계까지 거쳐 제1,2 소선(21,31)이 순차적으로 피복된 심선(11)은 전체 두께에 맞추어 이송 롤러 사이의 간격을 조절하면서 눌러서 이송함으로써, 다양한 두께의 소선이 피복되더라도 이송이 원활하게 진행될 수 있도록 한다.Meanwhile, the core wire 11 sequentially coated with the first and second element wires 21 and 31 through the outer skin forming step as described above is pressed and conveyed while adjusting the gap between the conveying rollers according to the overall thickness, thereby providing various thicknesses. Even if the wire is coated, the transfer can proceed smoothly.

본 발명에서는 이단 피복에 대해 설명하였으나, 필요에 따라 여러 대의 소선 꼬임 장치를 수직으로 배치시켜 3단, 4단 등 다단으로 연속 피복할 수 있음은 당업자에게 자명하다 하겠다.In the present invention, the two-stage coating is described, but it will be apparent to those skilled in the art that a plurality of strand twisting apparatuses can be vertically arranged in three stages, four stages, and the like, in order to continuously cover the two stages.

이와 같이 본 발명에 따른 바람직한 실시예를 살펴보았으며, 앞서 설명된 실시예 이외에도 본 발명이 그 취지나 범주에서 벗어남이 없이 다른 특정 형태로 구체화될 수 있다는 사실은 해당 기술분야에 있어 통상의 지식을 가진 자에게는 자명한 것이다.As described above, a preferred embodiment according to the present invention has been described, and the fact that the present invention can be embodied in other specific forms in addition to the above-described embodiments without departing from the spirit or scope thereof is known to those skilled in the art. It is obvious to those who have it.

그러므로, 상술된 실시예는 제한적인 것이 아니라 예시적인 것으로 여겨져야 하며, 이에 따라 본 발명은 상술한 설명에 한정되지 않고 첨부된 청구항의 범주 및 그 동등 범위 내에서 변경될 수 있다.Therefore, the above-described embodiments should be regarded as illustrative rather than restrictive, and thus, the present invention is not limited to the above description but may be modified within the scope of the appended claims and their equivalents.
