본 발명은 자동차 타이어 코드지 권취용 쉘의 개량발명에 관한 것인데 보다 구체적인 것은, 철제원통으로 되어 표면에 산화방지피막을 형성한 쉘외통과, 쉘외통 중심부에 배치되어 쉘의 중심을 유지하고, 회전축 작용을 하는 4각관체로 된 철제심관과, 철제원판으로 되어 철제심관 외주에 일정간격으로 배치되어, 중심구멍이 철제심관에 끼워져 용접되고, 외주면이 쉘외통 내주면에 용접되는 보강원판으로 이루어지는 타이어 코드지 권취용 쉘에 있어서, 쉘외통과 철제심관 사이에 개입되는 보강원판을 철제가 아닌 목제합판제 보강원판으로 형성하여 보강원판의 두께가 12~24mm 되게 함으로써, 쉘외통과 철제심관이 보강원판과 접촉할 때, 결합면이 넓어지고, 목재 특유의 완충력이 발휘되어 지지력이 강화됨으로써, 전체적인 강도가 높아져 쉘구조체의 진원이 유지되고, 중심축이 휘어지는 것을 막아 권취되는 타이어코드지의 구김이나 비틀림이 방지되어 타이어코드지의 사층이 정상적으로 유지되므로 품질저하가 발생하지 않고, 보강원판의 부식이 방지되어 내구성이 높아지며, 철제심관과 보강원판의 결합부에 합성수지제 접착제를 사용함으로써, 용접시와 달리 결합부에서의 충격 완충작용이 가능하기 때문에 철제심관의 파단을 방지할 수 있으며, 쉘의 중량을 가볍게 하여 사용 단계에서 발생하는 에너지 비용이 절약되고, 제조가격이 절감되어 경제적인 제품이 되게 한 것이다.The present invention relates to an improved invention of a shell for winding automotive tire cord paper, and more specifically, a shell outer tube made of an iron cylinder and formed with an anti-oxidation film on the surface, and disposed at the center of the shell outer cylinder to maintain the center of the shell, and rotate the shaft Tire cord paper consisting of a steel core tube made of a rectangular tube that acts, and a reinforcing disk made of iron disks and arranged at regular intervals on the outer periphery of the iron core tube, the center hole is inserted into the iron core tube and welded, and the outer peripheral surface is welded to the inner peripheral surface of the shell outer cylinder In the shell for winding, the reinforcing disc intervening between the shell outer tube and the iron core pipe is formed of a wooden plywood reinforcing disc instead of iron, so that the thickness of the reinforcing disc is 12 to 24 mm, so that the shell outer barrel and the iron core pipe are in contact with the reinforcing disc When this is done, the bonding surface is widened, the unique buffering power of wood is exhibited, and the supporting power is strengthened, thereby increasing the overall strength and maintaining the roundness of the shell structure, preventing the central axis from being bent and preventing wrinkling or torsion of the tire cord paper being wound. Since the four layers of tire cord paper are maintained normally, there is no deterioration in quality, corrosion of the reinforcing disc is prevented and durability is increased. It is possible to prevent the breakage of the iron core pipe because it can cushion the impact, and by making the shell light weight, the energy cost generated during the use stage is saved, and the manufacturing price is reduced, making it an economical product.

종래의 타이어코드지 권취용 쉘은 철제 원통으로 된 쉘외통과 쉘외통 중심에 4각관체로 된 철제심관을 배치하고, 4각관체의 양단부를 쉘외통 양단에 배치한 마구리원판 중심공에 끼워 용접하고, 철제심관과 쉘외통 사이에 일정간격으로 다수의 철제보강원판을 배치하여, 보강원판의 중심구멍은 철제심관 외면에 끼워 용접하고, 보강원판의 외주면은 쉘외통의 내주면에 용접하기 때문에 보강원판이 쉘외통과 철제심관에 결합하는 결합면이 좁게 이루어져 지지력이 부족하게 되고, 쉘외통에 압력이 가해지면 쉘외통에서 보강원판으로 집중되는 압력의 완충력이 부족하게 되므로, 큰 압력을 받으면 보강원판이 쉽게 변형되므로 쉘외통의 진원유지가 어렵고, 쉘구조체의 중심축이 휘어지므로 쉘에 감겨진 타이어코드지에 구김이나 비틀림이 발생하여 사층유지가 변형되므로 품질저하가 발생하게 되고, 철제심관이 철제보강원판이라 부식이 용이하여 내구성이 떨어지고, 가격이 비싸게 되며, 중량이 커서 사용단계에서 에너지 비용이 많아지는 불편이 있었다.In the conventional shell for winding tire cord paper, a steel core tube made of a square tube is placed in the center of a shell outer cylinder made of an iron cylinder and the outer shell, and both ends of the tube body are welded into the center hole of a magneto disk arranged at both ends of the shell outer cylinder. , by placing a number of steel reinforcing discs at regular intervals between the iron core pipe and the shell outer cylinder, the center hole of the reinforcing disc is welded to the outer surface of the iron core pipe, and the outer circumferential surface of the reinforcing disc is welded to the inner circumferential surface of the shell outer cylinder. Since the coupling surface for coupling to the outer shell and steel core is narrow, the bearing capacity is insufficient, and when pressure is applied to the outer shell, the buffering power of the pressure concentrated from the outer shell to the reinforcing disk is insufficient. Because it is deformed, it is difficult to maintain the original shape of the outer shell, and since the central axis of the shell structure is bent, creases or torsion occurs in the tire cord wrapped around the shell, and the four-layer maintenance is deformed, resulting in deterioration of quality. It is easy to corrode, so the durability is reduced, the price is high, and the energy cost is high in the use stage due to the large weight.

특허등록 제10-0351176호Patent Registration No. 10-0351176

본 발명은 상기 불편을 해소하기 위하여 금속제 보강원판 대신 소정두께를 가지는 목제합판으로 보강원판을 만들어 배치함으로써, 권취용 쉘의 전체의 중량을 줄이고, 쉘외통과 보강원판과의 결합면을 넓게 하여 지지력을 강화시키고, 목제합판의 작용으로 압력의 분산과 완충작용이 탁월하여 파열이나 파단이 방지될 뿐 아니라, 부식되지 않아 내구성을 유지할 수 있고, 쉘외통의 진원이 유지되고, 쉘구조의 중심축이 휘어지지 않게 강도를 발휘하므로 쉘제품에 감겨진 타이어코드지의 구김이나 비틀림이 발생되지 않아 품질이 보증되고 쉘구조체의 제조비용이 절감되고, 중량이 경감되어 에너지 비용이 경감되는 경제적인 제품이 되게 한 것이다.In order to solve the above inconvenience, the present invention makes and arranges a reinforcing disk with a wooden plywood having a predetermined thickness instead of a metal reinforcing disk, thereby reducing the overall weight of the shell for winding and widening the coupling surface between the shell outer cylinder and the reinforcing disk to increase the bearing capacity In addition to preventing rupture or breakage, as well as preventing rupture or fracture due to the action of wooden plywood, the pressure distribution and buffering action are excellent, and durability can be maintained without corrosion. As it exerts strength without bending, wrinkling or twisting of the tire cord paper wound around the shell product does not occur, ensuring quality, reducing the manufacturing cost of the shell structure, and reducing the weight, making it an economical product that reduces energy costs. will be.

본 발명은 철제원통으로 되어 표면에 산화방지피막(1a)을 형성하거나, 표면에 일정두께의 종이피막(1b)을 형성하는 방법 중에서 선택되는 방법으로 표면처리를 한 쉘외통(1)과, 쉘외통 중심부에 배치되고, 양단부가 쉘외통 양단부에 부착된 철제마구리(2) 중심구멍(2a)에 끼워져 용접되는 4각관체로 된 철제심관(3)과, 원판으로 되어 쉘외통(1)과, 철제심관(3) 사이에 일정간격으로 배치되고, 중심부에 형성된 4각형구멍(4b)에 철제심관(3)이 끼워져 용접되고, 외주면(4a)은 쉘외통(1)의 내주면에 용접되어 고정되는 보강원판(4)으로 이루어지는 타이어코드지 권취용 쉘에 있어서,The present invention is made of an iron cylinder to form an anti-oxidation film (1a) on the surface, or a method selected from a method of forming a paper film (1b) of a certain thickness on the surface of the shell outer cylinder (1) and the shell It is arranged in the center of the outer cylinder, and both ends are made of iron ferrule 2 attached to both ends of the shell outer cylinder, the iron core tube 3 made of a quadrangular tube body that is inserted into the center hole 2a and welded, the shell outer cylinder 1 as a disk, and iron The core pipe 3 is arranged at regular intervals between the core pipes 3, and the iron core pipe 3 is inserted and welded into the rectangular hole 4b formed in the center, and the outer circumferential surface 4a is welded to the inner circumferential surface of the shell outer cylinder 1 and fixed reinforcement In the tire cord paper winding shell consisting of a disc (4),

상기 보강원판(4)은 철제 보강원판 대신 일정두께를 가지는 목제합판에서 선택되고, 상기 목제합판은 라왕을 비롯한 여러종류의 나무 중에서 선택된 목재를 얇게 켜서 만든 다수매의 베니어를 결방향이 서로 직각되게 중첩시키고, 열경화성수지를 접착제로 사용하여 가열압착 경화시켜, 두께 12~24mm 되게 만든 목제합판이 선택되어 상기 목제합판을 원형으로 절단한 목제합판제 보강원판(40)으로 만들어지고, 상기 목제합판제 보강원판은 외경(40a)이 쉘외통(1) 내경보다 0.3~1.0mm 확장되는 직경을 가지도록 제작되어 중심부에는 철제심관(3)이 끼워지는 4각형구멍(40b)을 구비하며, 중심부의 4각형구멍(40b)에 철제심관(3)을 끼워져 합성수지 접착제로 접착되고, 외주연(40b)은 쉘외통(1) 내주면에 억지끼움으로 결합하여 외주면이 쉘외통의 내주면을 확장시키면서 강제 결합함으로써, 쉘외통의 복귀탄력을 받아 결합부가 서로 밀착되는 구성으로 이루어진다.The reinforcing disc 4 is selected from a wooden plywood having a certain thickness instead of an iron reinforcing disc, and the wooden plywood is a plurality of veneers made by thinly slicing wood selected from various types of wood, including Rawang, so that the grain direction is perpendicular to each other. A wooden plywood board made to be overlapped and cured by heat compression using a thermosetting resin as an adhesive to have a thickness of 12 to 24 mm is selected, and the wooden plywood is made into a reinforcing plate 40 made of a circular cut of the wooden plywood, and the wooden plywood The reinforcing disk is manufactured so that the outer diameter (40a) has a diameter that is 0.3 to 1.0 mm larger than the inner diameter of the shell outer cylinder (1), and has a square hole (40b) into which the iron core pipe (3) is fitted in the center, and 4 of the center The iron core pipe 3 is inserted into the square hole 40b and bonded with a synthetic resin adhesive, and the outer periphery 40b is coupled to the inner circumferential surface of the shell outer cylinder 1 by force fitting, and the outer circumferential surface is forcefully coupled while expanding the inner circumferential surface of the shell outer cylinder, It consists of a configuration in which the coupling part is in close contact with each other by receiving the return elasticity of the shell outer cylinder.

이때, 목제합판제 보강원판은 철제심판에 4~8개가 등간격에 배치될 수 있다.At this time, 4 to 8 reinforcing discs made of wooden plywood may be arranged at equal intervals on the iron plate.

이와 같이 된 본 발명은 쉘외통(1) 내주면과 철제심관(3) 사이에 일정두께를 가지는 목제합판제 보강원판(40)이 배치되어 쉘외통 내주면에 강제 삽입으로 결합되고, 강제삽입시에는 보강원판이 쉘외통의 내주면을 확장시키면서 강제 결합하여 보강원판의 외주면이 쉘외통의 복귀탄력을 받으면서 쉘외통내면에 밀착결합되기 때문에 용접 없이 결합이 이루어지고, 목제합판의 두께가 12~24mm 로 넓어서 쉘외통과 접촉면이 넓어지므로 지지력이 확대되어 안전한 결합이 이루어지게 된다.In the present invention as described above, a wooden plywood reinforcing disc 40 having a certain thickness is disposed between the inner circumferential surface of the shell outer cylinder 1 and the iron core pipe 3, and is coupled to the inner circumferential surface of the shell outer cylinder by force insertion, and reinforcement during forced insertion Since the disc is forcibly joined while expanding the inner circumferential surface of the shell outer cylinder, the outer circumferential surface of the reinforcing disc is closely coupled to the shell outer cylinder inner surface while receiving the return elasticity of the shell outer cylinder, so the connection is made without welding. Since the outer cylinder and the contact surface are widened, the bearing capacity is expanded and a safe coupling is achieved.

또, 목제합판 보강원판은 목제 특유의 끈기와 완충력이 작용하므로 쉘외통에 압력이 가해지면 압력을 분산시키고 완충시키므로, 쉘외통을 보다 안전하게 지지할 수 있게 되므로, 쉘외통이 감당하는 하중강도가 2배이상 증가하고, 쉘외통의 진원이 유지되고, 중심축이 휘어지지 않아 쉘외통에 감겨지는 타이어코드지의 구김과 비틀림을 방지하므로 타이어코드지의 변형되는 것을 막아 품질저하를 막을 수 있고, 철제심관(3)과의 결합부에 합성수지제 접착제가 사용되므로, 접착부에서의 완충작용이 양호하여 철제심관에 작용하는 밴딩모멘트를 완화시킬 수 있고, 이로인해 철제심관이 파열되거나 파단되는 것을 예방할 수 있기 때문에 안전한 권취용 쉘을 유지할 수 있게 되며, 목제합판제 보강원판이므로 부식되거나, 변형되지 않아 내구성이 유지되고, 가격이 저렴하고 중량이 가벼워지므로, 사용단계에서 에너지 비용이 절감되는 경제적인 제품을 만들 수 있는 이점이 있다.In addition, the wooden plywood reinforcing disc has the unique tenacity and buffering force of wood, so when pressure is applied to the outer shell, the pressure is distributed and buffered, so that the outer shell can be supported more safely. It increases more than twice, maintains the roundness of the outer shell, and prevents wrinkling and twisting of the tire cord paper wound around the outer shell as the central axis does not bend, thus preventing the deformation of the tire cord paper and deterioration of quality. 3) Since a synthetic resin adhesive is used in the bonding part, the buffering action at the bonding part is good and the bending moment acting on the iron core pipe can be alleviated, which prevents the iron core pipe from being ruptured or ruptured. It is possible to maintain the shell for winding, and as it is a wooden plywood reinforcing plate, it is not corroded or deformed, so durability is maintained. There is an advantage.
