본 발명은 범퍼의 도막을 제거하는 장치에 관한 것으로서, 특히 회전부재와 고정부재 사이에 압착되면서 전단력을 받아 도막이 분리되어질 수 있게 한 범퍼도막 제거장치에 관한 것이다.The present invention relates to a device for removing a coating film of a bumper, and more particularly, to a bumper coating film removing device that allows the coating film to be separated by a shear force while being pressed between the rotating member and the fixing member.
일반적으로 범퍼는 전량산업 폐기물로서 소각 또는 매립되어지는 폐기과정을 거치고 있어 환경에 큰 해를 끼치고 있는 실정이다.In general, the bumper is an industrial waste, which is incinerated or disposed of, which is causing a great harm to the environment.
따라서, 최근 일부에서는 이러한 범퍼 특히, 범퍼커버를 일정한 크기로 분쇄하여 재활용하고자 연구, 노력하고 있으나, 범퍼커버의 표면에 처리된 폴리우레탄계 페인트를 제거하는 과제가 문제점 예컨대, 페인트는 열경화성 수지로서 범퍼커버의 원재료인 열가소성 수지와 혼입하여 성형하여도 녹지 않고 잔존하기 때문에 수지 고유의 특성을 유지할 수 없게 되는 문제점으로서 대두되게 되었다.Therefore, in recent years, such a bumper, in particular, the research and effort to crush and recycle the bumper cover to a certain size, but the problem of removing the polyurethane-based paint treated on the surface of the bumper cover problem, for example, the paint as a thermosetting resin bumper cover It is a problem that the inherent properties of the resin cannot be maintained because the resin remains unmelted even when mixed with the thermoplastic resin which is a raw material.
이와같은 페인트 제거기술에는 다양한 기술이 소개되고 있는 실정이나 화학적 방법, 물리적 방법 등에 대해 각각의 장단점이 있고, 비용측면도 고려가 된 효과적인 페인트 제거기술에 대한 필요성이 점차 높아지고 있는 추세이다.Such paint removal techniques have advantages and disadvantages for various situations, chemical methods, physical methods, etc., and the need for an effective paint removal technique, which is considered in terms of cost, is gradually increasing.
따라서, 본 발명은 이와 같은 점을 감안하여 안출한 것으로서, 회전부재와 고정부재 사이에 재료를 투입하고, 재료가 상기 두 부재 사이에서 압착되는 과정에서 상호간의 열팽창 계수 차이에 의한 계면 분리작용이 이루어지게 함으로써, 범퍼 커버상의 페인트를 비교적 손쉽게 제거할 수 있게 한 범퍼도막 제거장치를 제공하는데 그 목적이 있는 것이다.Accordingly, the present invention has been made in view of this point, the material is introduced between the rotating member and the fixing member, and the interface separation action by the difference in the coefficient of thermal expansion between each other in the process of the material is pressed between the two members is made It is an object of the present invention to provide a bumper film removing apparatus which makes it possible to remove paint on the bumper cover relatively easily.
이하, 첨부도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 발명은 편심된 사다리꼴 원기둥 형상의 회전부재(10)와, 이것의 외주부를 감싸면서 상부에는 재료투입면(11)을 갖는 고정부재(12)와, 상기 회전부재(10)와 직결되는 구동수단(13)으로 구성되어서 이루어진 것이다.The present invention provides an eccentric trapezoidal cylindrical rotating member (10), a fixing member (12) having a material input surface (11) at the top while surrounding the outer peripheral portion thereof, and a driving means connected directly to the rotating member (10). It consists of (13).
이를 좀더 상세히 설명하면, 첨부도면 제1도는 본 발명의 범퍼도막 제거장치를 나타내는 사시도로서, 상기 회전부재(10)는 상단의 직경이 하단의 그것보다 작은 사다리꼴 원기둥 형상을 하고 있되, 각각의 직경을 수직 관통하는 각 중심세로축선이 서로 일치하지 않는 편심된 형상을 하고 있으며, 하단 전체 외주연에서 수직으로 연장된 선이 상단 외주연의 적어도 한 점 이상에서 만날 수 있도록 된 편심정도를 갖는다. 이때, 상기 회전부재(10)의 윗면은 정점을 가지는 원뿔형상으로 이루어져 있어서, 후술하는 고정부재(12)의 수직구멍(14)으로 투입되는 재료를 안쪽으로 유도할 수 있게 된다.To explain this in more detail, Figure 1 is a perspective view showing the bumper coating film removing apparatus of the present invention, the rotating member 10 has a trapezoidal cylindrical shape of the upper diameter is smaller than that of the lower end, each diameter Each of the vertical longitudinal axis passes through the eccentric shape, which does not coincide with each other, and has a eccentricity such that a line extending vertically from the entire outer periphery of the bottom meets at least one point of the upper periphery. At this time, the upper surface of the rotating member 10 is made of a cone shape having a vertex, it is possible to guide the material introduced into the vertical hole 14 of the fixing member 12 to be described later.
또한, 상기 고정부재(12)는 적정 자체 중량을 갖는 육면체로 이루어져 있으며, 중심부에는 원형의 수직구멍(14)이 형성되어 있다. 특히, 고정부재(14)의 윗면에는 상기 수직구멍(14)의 상단 주연부에서부터 바깥쪽으로 확장되면서 연장되는 테이퍼면으로 이루어진 재료투입면(11)이 형성되어 있고, 이 면을 이용하여 수직구멍(14)으로 재료의 투입이 이루어지게 된다. 여기서, 수직구멍(14)의 내주면은 열처리 가공이 되어 있어서, 여기에 압착되는 재료와의 마찰간섭에 의해서도 충분히 견딜 수 있는 내마모성을 갖게 된다.In addition, the fixing member 12 is made of a hexahedron having a proper weight of its own, a circular vertical hole 14 is formed in the center. In particular, the top surface of the fixing member 14 is formed with a material input surface 11 made of a tapered surface extending outwardly extending from the upper peripheral edge of the vertical hole 14, by using the vertical hole 14 The input of material is made with). Here, the inner circumferential surface of the vertical hole 14 is subjected to heat treatment, so that the inner peripheral surface of the vertical hole 14 has abrasion resistance that can be sufficiently tolerated by frictional interference with the material pressed therein.
또한, 상기 회전부재(10)를 회전시켜 주는 구동수단(13)은 통상의 모터가 적용될 수 있으며, 회전부재(10)의 축과 직결 또는 별도의 전동부재 예컨대, 기어전동부재를 매개로 하여 연결되어 있다.In addition, the driving means 13 for rotating the rotary member 10 may be applied to a conventional motor, connected directly or directly through a shaft of the rotary member 10 or a separate transmission member, for example, via a gear transmission member. It is.
여기서, 미설명부호 15는 회전부재(10)의 축과 모터의 축을 연결하는 커플링을 나타낸다.Here, reference numeral 15 denotes a coupling connecting the shaft of the rotating member 10 and the shaft of the motor.
이와같이 구성된 상기 회전부재(10)와 고정부재(12)는, 첨부도면 제2도에 도시한 바와 같이, 고정부재(12)의 수직구멍(14) 내측으로 회전부재(10)가 수직 위치되는 상호간의 결합구조를 갖게 된다. 이렇게 결합된 상태에서 회전부재(10)의 외주면과 수직구멍(14)의 내주면 사이에는 간격(G)이 형성되게 되고, 이때의 간격(G)은 회전부재(10)가 갖는 형상의 특성상 아래쪽으로 갈수록 점차 좁아지게 되며, 최하단부는 도막이 제거된 재료의 두께가 겨우 통과할 수 있는 정도의 간격(G) 예컨대 0.5㎜~0.7㎜ 정도의 간격(G)이 형성되게 된다.The rotating member 10 and the fixing member 12 configured as described above are mutually positioned such that the rotating member 10 is vertically positioned inside the vertical hole 14 of the fixing member 12, as shown in FIG. It has a coupling structure of. In this coupled state, a gap G is formed between the outer circumferential surface of the rotating member 10 and the inner circumferential surface of the vertical hole 14, and the gap G is lowered due to the characteristics of the shape of the rotating member 10. It becomes narrower gradually, and the lowermost part forms the space | interval G such that the thickness of the material from which the coating film was removed can barely pass, for example, the space | interval G of about 0.5 mm-0.7 mm.
한편, 상기와 같은 본 발명의 작용효과를 설명하면, 먼저 적당한 크기로 선절단 처리된 재료 예컨대, 범퍼커버를 고정부재(12)의 테이퍼면(15)을 통하여 그 저부의 수직구멍(14) 내부로 투입하게 되면, 이때의 재료는 고속회전하고 있는 회전부재(10)의 외주면과 수직구멍(14)의 내주면 사이 하단부위에서 압착되고, 이때 받는 전단력에 의해 재료에 표면처리된 페인트가 분리되게 된다.On the other hand, when explaining the operation and effect of the present invention as described above, first, the material, such as bumper cover pre-cut to the appropriate size, through the tapered surface 15 of the fixing member 12 inside the vertical hole 14 of the bottom In this case, the material is pressed at the lower end portion between the outer circumferential surface of the rotating member 10 and the inner circumferential surface of the vertical hole 14 which are rotating at a high speed, and the paint surface-treated on the material is separated by the shearing force.
즉, 첨부도면 제3도에 도시한 바와 같이, 열가소성 수지인 범퍼의 원재료(a)가 압착에 의한 열을 받아 연신됨에 따라 그 표면층의 페인트(b)는 길이방향으로 분할되면서 원재료층과의 계면적 저하를 가져와 상호 분리작용이 이루어지게 되며, 이렇게 페인트가 분리된 재료는 수집되어 재사용 가능하게 된다.That is, as shown in Fig. 3 of the accompanying drawings, as the raw material (a) of the bumper, which is a thermoplastic resin, is stretched under heat by pressing, the paint (b) of the surface layer is divided in the longitudinal direction, and the system is formed with the raw material layer. This results in a reduction in area, resulting in mutual separation, and the material from which the paint is separated is collected and made reusable.
이상에서와 같이 본 발명은 간단한 구조의 범퍼도막 제거장치를 제공함으로써, 재료의 재활용이 가능하고, 이로인해 자원절약 측면에서의 큰 잇점을 얻어낼 수 있는 장점이 있는 것이다.As described above, the present invention provides an apparatus for removing a bumper film having a simple structure, which enables recycling of materials, thereby obtaining a large advantage in terms of resource saving.
