완충부재가 구비된 코어{PAPER CORE HAVING DAMPING MEMBER}Core with shock absorbing member {PAPER CORE HAVING DAMPING MEMBER}

도1 은 본 고안의 바람직한 실시예에 따른 완충재가 구비된 코어를 도시하는 사시도이다.1 is a perspective view showing a core provided with a cushioning material according to a preferred embodiment of the present invention.

도2 는 도1 에 도시된 코어의 "A-A" 단면도이다.FIG. 2 is a cross-sectional view "A-A" of the core shown in FIG.

도3 은 도2 에 도시된 코어의 "B" 부분을 확대하여 보여주는 부분 확대도이다.FIG. 3 is an enlarged view of the portion “B” of the core illustrated in FIG. 2 in an enlarged manner.

본 고안은 코어에 관한 것으로, 더욱 상세하게는 완충부재를 구비함으로써 필름 등을 권취하는 경우 필름의 두께로 인하여 발생하는 턱을 완충작용에 의하여 방지할 수 있는 코어에 관한 것이다.The present invention relates to a core, and more particularly, to a core capable of preventing a jaw generated due to the thickness of a film by a buffering action when the film or the like is wound by providing a buffer member.

일반적으로 코어는 지류나 필름류(이하, 권취물)를 롤(Roll) 상태로 감기 위한 관으로서, 대체적으로 다수매의 종이가 중첩되어 감겨짐으로서 제조된다.In general, the core is a tube for winding papers or films (hereinafter, wound) in a roll state, and is generally manufactured by winding up a plurality of sheets of paper.

이러한 코어는 그 제조공정에 있어서, 다수매의 종이를 중첩하여 원통형상으로 와인딩하고, 건조하는 공정과, 건조 공정 후 롤러 장치를 이용하여 코어의 외주에 표면지를 입히는 공정과, 표면지의 외주에 왁스를 입히는 왁싱 공정과, 코어표 면지을 경화시켜 표면 조도를 향상시키기 위하여(표면을 매끄럽게함) 실린더의 내부로 코어를 통과시켜 주는 압출 공정이 순차적으로 진행된다. 그리고, 이러한 공정에 의하여 제조된 코어에 권취물을 권취하여 사용되게 된다.In the manufacturing process, the core is overlapped with a plurality of sheets of paper, wound in a cylindrical shape, dried, coated with surface roller on the outer circumference of the core using a roller device after the drying process, and waxed on the outer circumference of the surface paper. The waxing process of coating and the extrusion process of passing the core through the inside of the cylinder in order to harden the core surface paper to improve the surface roughness (smooth the surface) proceed sequentially. Then, the wound is wound around the core manufactured by such a process.

그러나 상기 코어는 다수의 종이를 적층하여 나선형 방식(Spiral)으로 제조하고 있어 여기에 권취물인 필름을 권취하면 나선형자국이 필름에 전사되어 상품의 가치 저하는 물론 후 공정에(2차공정) 많은 문제점을 발생 시키고 있다.However, the core is manufactured by stacking a plurality of papers in a spiral manner, and when the film is wound up, the spiral marks are transferred to the film, thereby degrading the value of the product as well as many problems in the subsequent process (secondary process). It is raising.

이러한 문제점을 해결하기 위하여 나선형으로 제조된 코어에 표면지를 감아서 사용하는데 이때에도 표면지의 두께에 의한 턱 발생을 방지하기위하여 특별히 가공된 표면지를 사용하여 코어의 표면에 이음매가 없도록 한다. 이때, 사용되는 코어를 시임레스 코어(Seamless Core)라한다. In order to solve this problem, the surface paper is wound around the spirally manufactured core, and in this case, the surface of the core is free from seams using a specially processed surface paper to prevent the occurrence of tuck caused by the thickness of the surface paper. In this case, the core used is referred to as a seamless core.

그리고, 최근에는 프라스틱 필름(특히 PET필름)의 다양한 용도 개발로 인하여 LCD, 벽걸이TV, 휴대폰 등의 모니터에 사용되는 IT용 필름은 시임레스 코어에 권취 하여도 그 필름 자체의 두께에 의하여 턱이 발생하고 그 발생된 턱에 의하여 자국이 전사되어 많은 문제점을 발생시키고 있다.Recently, due to the development of various uses of plastic films (especially PET films), IT films used for monitors such as LCDs, wall-mounted TVs, mobile phones, etc., have a chin caused by the thickness of the film itself even when wound on a seamless core. The marks are transferred by the generated jaws, causing many problems.

따라서, 본 고안은 상기한 문제점을 해결하기 위하여 고안된 것으로서, 본 고안의 목적은 코어에 완충부재를 적용함으로써 다수의 필름을 권취하는 경우, 이 완충부재의 완충작용에 의하여 필름의 턱에 의한 자국이 전사되는 것을 방지 또는 감소시킴으로써 IT용 및 산업용 필름의 품질을 향상시킬 수 있는 코어를 제공하는데 있다.Therefore, the present invention is devised to solve the above problems, and an object of the present invention is to wound the film by the jaw of the film by the buffering action of the buffer member when applying the buffer member to the core. It is to provide a core that can improve the quality of IT and industrial film by preventing or reducing the transfer.

상기와 같은 목적을 달성하기 위하여, 본 고안의 바람직한 실시예는 중심관; 상기 중심관의 외부에 권취되어, 외력이 작용하는 경우 상기 중심관의 내측방향으로 완충될 수 있는 완충부재; 그리고 상기 완충부재의 외부면에 구비되어 권취물이 권취되는 표면지를 포함하며, 상기 권취물의 권취압력에 의하여 상기 완충부재가 내측으로 완충됨으로써 권취물의 두께로 인한 턱이 발생되는 것을 방지할 수 있는 코어를 포함한다.In order to achieve the above object, a preferred embodiment of the present invention is a central tube; A shock absorbing member wound around the outside of the center tube and capable of being buffered inwardly of the center tube when an external force is applied; And a surface paper provided on the outer surface of the cushioning member, the surface of which the wound is wound, and the core which can prevent the occurrence of a jaw due to the thickness of the wound by buffering the buffer member inward by the winding pressure of the wound. It includes.

이하, 첨부 도면을 참조하여 본 고안의 바람직한 실시예에 따른 코어의 구조를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the structure of the core according to a preferred embodiment of the present invention.

도1 과 도2 에 도시된 바와 같이, 본 고안이 제안하는 코어(Core;1)는 권취물(3;이하, 필름)을 감는 기능을 수행한다. 이러한 코어(1)는 중심관(2)과, 상기 중심관(2)의 외부에 권취되어, 외력이 작용하는 경우 상기 중심관(2)의 내측방향으로 완충될 있는 완충부재(5)와, 그리고 상기 완충부재(5)의 외부면에 권취되어 필름(3)이 권취되는 표면지(7)를 포함한다.As shown in Figure 1 and 2, the core (Core) 1 proposed by the present invention performs the function of winding the wound (hereinafter, 3). The core 1 is wound around the center tube (2), the outside of the center tube (2), the buffer member (5) which can be buffered in the inner direction of the center tube (2) when an external force is applied, And a surface paper 7 wound around the outer surface of the buffer member 5 to which the film 3 is wound.

이러한 구조를 갖는 코어에 있어서, 상기 중심관(2)은 통상적인 형상의 관체를 포함한다. 즉, 다수매의 종이를 중첩적으로 권취하여 접착제 등에 의하여 부착시킴으로써 원통형상을 갖는다. 상기 중심관(2)은 그 목적 및 용도에 따라 적절한 직경으로 제조될 수 있다.In the core having such a structure, the center tube 2 includes a tube body having a conventional shape. That is, it has a cylindrical shape by winding up a plurality of sheets of paper overlapping and attaching them with an adhesive or the like. The center tube 2 may be manufactured to a suitable diameter according to the purpose and use.

그리고, 상기 완충부재(5)는 상기한 중심관(2)의 외주면에 감겨지며, 완충성을 갖는 재질로 형성된다. 따라서, 코어(1)에 필름 등을 권취하는 경우, 이 완충부 재(5)가 중심방향으로 적절하게 완충될 수 있다.The shock absorbing member 5 is wound around the outer circumferential surface of the center tube 2 and is formed of a material having a cushioning property. Therefore, when winding a film etc. in the core 1, this buffer part 5 can be buffered appropriately to a center direction.

이러한 완충부재(5)는 종이, 스폰지, 완충성을 갖는 합성수지 및 발포체, 러버 등을 포함한다. 이때, 상기 종이는 적절하게 가공함으로써 탄성력을 갖도록 한다.The buffer member 5 includes a paper, a sponge, a synthetic resin having a cushioning property, a foam, a rubber, and the like. At this time, the paper has an elastic force by appropriately processing.

또한, 상기 합성수지로는 비닐, 폴리스티렌, 폴리에틸렌, 페놀수지, 아세트산셀룰로오스, 우레탄 등을 포함한다.In addition, the synthetic resin includes vinyl, polystyrene, polyethylene, phenol resin, cellulose acetate, urethane and the like.

그리고, 상기 발포체로는 폴리플로필렌 수지(Polypropylene;PP), 폴리스틸렌 수지(Polystyrene;PS), 발포 폴리플로필렌 수지(Expanded Polypropylene;EPP), 발포 폴리스티렌 수지(Expandable Polystyrene;EPS) 등을 포함한다.The foam includes polypropylene (PP), polystyrene (PS), expanded polypropylene (EPP), expanded polystyrene (EPS), and the like.

따라서, 상기와 같은 재질로 형성된 완충부재(5)는 코어(1)에 필름 등이 감기는 경우 적절하게 완충될 수 있다.Therefore, the buffer member 5 formed of the above material may be appropriately buffered when a film or the like is wound around the core 1.

상기 표면지(7)는 이러한 완충부재(5)의 외주면에 부착된다. 즉, 표면지(7)가 완충부재(5)의 표면에 부착된 상태에서 완충부재(5)의 외주면을 따라 권취된다. The surface paper 7 is attached to the outer circumferential surface of the buffer member 5. That is, the surface paper 7 is wound along the outer circumferential surface of the buffer member 5 in a state where the surface paper 7 is attached to the surface of the buffer member 5.

이와 같이, 표면지(7)가 완충부재(5)의 외주면에 감겨진 후, 그 외주면에 필름(3)이 일정한 압력으로 권취될 수 있다.As such, after the surface paper 7 is wound on the outer circumferential surface of the buffer member 5, the film 3 may be wound on the outer circumferential surface at a constant pressure.

이때, 필름(3)이 코어(1)를 따라 최초로 1회전하여 감긴 후, 원위치에 복귀하였을 경우, 먼저 권취된 필름(11)의 상부에 감겨지게 됨으로써 점차 적층된다. 이때, 먼저 권취된 필름(11)의 두께로 인하여 나중 권취된 필름(13)상에 턱(9)이 발생한다.At this time, after the film 3 is first rolled along the core 1 and then returned to its original position, the film 3 is gradually laminated by being wound on the upper portion of the film 11 wound up. At this time, the jaw 9 is generated on the later wound film 13 due to the thickness of the film 11 first wound.

그리고, 필름(3)의 권취압력에 의하여 필름(3)이 반경방향으로 가압되며, 완 충부재(5)의 완충력에 의하여 표면지(7)가 일정 깊이로 눌리게 된다.Then, the film 3 is pressed in the radial direction by the winding pressure of the film 3, the surface paper 7 is pressed to a certain depth by the buffering force of the buffer member (5).

따라서, 필름(3)이 코어(1)에 권취되는 경우, 필름(3)의 두께로 인한 턱(9)이 전사되는 것을 방지할 수 있다.Therefore, when the film 3 is wound around the core 1, it is possible to prevent the jaw 9 due to the thickness of the film 3 from being transferred.

그리고, 상기한 코어에 있어서, 완충재를 권취하는 방식은 나선권취방식(Spiral)이나 평권취 방식중 어느 하나의 방식으로 가능하다.In the core described above, the method of winding up the cushioning material can be performed by either a spiral winding method or a flat winding method.

한편, 상기에서는 완충부재의 표면에 표면지가 구비되는 것으로 설명하였지만, 본 고안은 이에 한정되는 것은 아니고 완충부재의 표면에 직접 필름이 권취될 수도 있다.On the other hand, in the above it was described that the surface paper is provided on the surface of the buffer member, the present invention is not limited to this, the film may be directly wound on the surface of the buffer member.

이 경우에도, 표면지가 구비된 경우와 동일한 효력, 즉 필름상에 턱이 발생하는 것을 방지할 수 있다.Also in this case, it is possible to prevent the occurrence of jaws on the film in the same effect as that provided with the surface paper.

또는, 본 발명의 다른 실시예로써 완충부재와 표면지를 일체로 가공하여 코어에 적용함으로써 완충효과를 갖도록 할 수도 있다.Alternatively, in another embodiment of the present invention, the buffer member and the surface paper may be integrally processed and applied to the core to have a buffer effect.

또는, 본 발명의 또 다른 실시예로써 표면지를 완충성이 있는 재질로 형성할 수도 있다.Alternatively, as another embodiment of the present invention, the surface paper may be formed of a buffer material.

이와 같이 본 고안의 바람직한 실시예에 따른 코어는 완충재를 적용함으로써 다수의 필름을 권취하는 경우, 이 완충재의 완충작용에 의하여 필름의 두께로 인한 턱이 발생하는 것을 방지할 수 있는 장점이 있다.As described above, the core according to the preferred embodiment of the present invention has an advantage of preventing the occurrence of the jaw due to the thickness of the film due to the buffering action of the buffer when the buffer is applied to the plurality of films.

필름을 코어에 권취하는 경우, 필름에 발생할 수 있는 턱을 방지할 수 있음으로 품질유지가 용이한 장점이 있다.When the film is wound around the core, it is possible to prevent the jaw that may occur in the film, there is an advantage that easy quality maintenance.

본 고안은 당해 고안이 속하는 분야의 통상의 지식을 가진 자라면 누구든지 실용신안등록청구의 범위에서 청구하는 본 고안의 요지를 벗어나지 않고도 다양하게 변경실시 할 수 있으므로 상술한 특정의 바람직한 실시예에 한정되지 아니한다.The present invention can be variously modified without departing from the gist of the present invention claimed by any person having ordinary knowledge in the field to which the present invention belongs, so limited to the specific preferred embodiment described above Not.
