Description

판재의 제조장치 및 그 판재{Device for forming the slab and its slab}Device for manufacturing plate and its plate {Device for forming the slab and its slab}

본 발명은 토목.건축자재 또는 화물의 운송시 사용되는 컨테이너 바닥재 등으로 이용되는 판재를 일련의 기계적이고 자동적인 연속공정으로 압출성형시키는 판재의 제조장치 및 그 판재에 관한 것이다.The present invention relates to a plate manufacturing apparatus for extruding a sheet material used for civil engineering, building materials or container flooring used in the transportation of goods in a series of mechanical and automatic continuous process and the plate material.

토목이나 건축공사 시 거푸집 등으로 이용되는 각종 판재 또는, 컨테이너를 이용한 화물운송 시 그 화물을 충격으로부터 보호하기 위해 컨테이너의 바닥에 설치되는 바닥재 등은 목재를 주로 많이 이용하고 있었다.Various plate materials used as formwork for civil engineering and building construction, or flooring materials installed at the bottom of containers to protect the cargoes from impacts when transporting them using containers mainly used wood.

이러한 목재의 판재는 중량이고 보관 및 내구성이 저조한, 다시 설명하면 습기에 매우 취약하고 부패 등으로 인한 위생적인 문제가 따라 방습처리가 필히 요구되어 관리성이 용이하지 않았을 뿐아니라, 그 무게가 중량이어 운반 및 보관은 물론 작업에 많은 불편을 주고 있는 것이다. These wood boards are heavy, poorly stored and durable. In other words, they are very vulnerable to moisture and hygienic due to decay. Not only transportation and storage, but also a lot of inconvenience to work.

그리하여 근래에 와서는 충격흡수성이 우수하고 내구성과 세척 및 살균작업을 간편 용이하게 이룰 수 있음과 동시, 방습처리를 요하지 않는 합성수지 판재가 제조되어 공급되고 있다.Thus, in recent years, synthetic resin boards that are excellent in shock absorption, durable, easy to clean and sterilize, and do not require moisture proofing, have been manufactured and supplied.

이러한 합성수지제의 판재는 대략 압출 성형물로, 외피와 그 외피 내에 발포성의 충전재, 그리고 제품의 강도를 보다 향상 시키기 위해 판재의 단면형상 개선 또는 충전재에 형강제 또는 산업폐기물인 폐목이나 수지 등의 분쇄물로 이루는 보강재들을 삽입시킨 보강구조를 갖추고 있다.Such synthetic resin plate is an extrusion molding, and the shell and resins such as waste wood or resin, which is a form steel or industrial waste in the cross-sectional shape of the plate or the filler in order to improve the strength of the product and the foamable filler in the shell and the shell. Equipped with a reinforcement structure inserted into the reinforcement.

그런데 이러한 합성수지제의 판재에서 제품의 강도 향상을 위하여 설치되는 보강구조를 보면 상기에서와 같이 판재의 단면을 요철형상으로 이루어 강도를 높이거나 또는 별도의 보강재, 예를 들어 망형상의 보강사나 띠형상의 철재들 등의 보강재를 충전재에 인서트방식으로 설치하고 있는 것이다.However, when looking at the reinforcing structure installed to improve the strength of the product in the plate made of synthetic resin as described above, the cross section of the plate in the concave-convex shape to increase the strength or a separate reinforcing material, for example, mesh reinforcement or band shape Reinforcements such as steel are installed in the insert method.

그러나 이렇게 단면의 구조개선 또는 보강사나 철재 등으로 이루는 보강구조를 갖는 판재는 제조공정이 용이하지 않고 제품의 균일성은 물론 제품의 강도가 저조한 등의 많은 문제점이 따르고 있는 것으로, 판재는 외피 내에 충전되는 보충재의 밀도를 높이어 제품의 강도 향상을 필요로 하며 제품의 균일성은 물론 높은 생산성을 필요로 한다. 중량의 하중이 가해지는 판재의 경우에는 더욱 그러할 것이다.However, a plate having a structural improvement of a cross section or a reinforcing structure made of reinforcing yarn or steel is not easy to manufacture and has many problems such as uniformity of the product and low strength of the product. Increasing the density of the supplement requires an increase in the strength of the product and requires a high productivity as well as product uniformity. This is especially true in the case of plate loaded with heavy loads.

상기에서와 같은 토목.건축자재 또는 컨테이너 바닥재로 사용되는 합성수지제의 판재들은 일련의 압출 공정으로 제조되고 있는데, 대략 호퍼를 통해 투입되는 열가소성 수지원료가 제1압출기의 스크루케이스를 거치어 다이스로 압출되면서 1차적으로 외피를 압출성형함과 동시, 그 외피의 내측에 주로 폐합성수지를 이용해 발포성형되는 충전재가 제2압출기의 스크루케이스를 거치어 다이스로 압출 충진되어 2차 압출성형한 후 그 압출물을 진공흡착방식의 싸이징을 통과시키면서 소정의 형태로로 다듬고, 이렇게 정형화된 압출성형물을 수냉방식의 냉각과정을 이루어 완성된 성형물을 인출수단으로 인출하여 소기의 제품을 얻게 된다.Plates made of synthetic resin used as civil engineering, construction materials, or container flooring as described above are manufactured by a series of extrusion processes, and the thermoplastic water support material injected through the hopper is extruded through a screw case of the first extruder into a die. At the same time, the outer shell is first extruded and at the same time, the filler that is foamed mainly using waste synthetic resin is extruded and filled into a die through the screw case of the second extruder, and then the second extrudate is formed. This is refined to a predetermined shape while passing through the vacuum adsorption method, and the molded product thus formed is subjected to a cooling process of a water cooling method, and the finished molded product is taken out as a drawing means to obtain a desired product.

그리고 이러한 장치를 통해 제조된 제품의 높은 강도는 사이징을 통해 정형화되는 제품의 충전재 밀도, 그리고 충전재와 보강재의 밀접도를 높이게 하는 것과 직접적으로 관련된다. And the high strength of the product produced through such a device is directly related to increasing the filler density of the product to be shaped through sizing and the closeness of the filler and the reinforcement.

또 제품의 강도 유지를 위한 보강구조에서 단면의 형상을 이용시에는 다이스 등 제조장치의 구조가 복잡해지고 그 압출물의 구조 또한 단순하지 않아 수지물의 수축변화율 등으로 인해 생산성이 저조함은 물론 금형비 등의 설비 비용이 상승되는 문제점이 따르고 있고, 그리고 충전재에 별도의 보강재를 인서트 시키는 경우는 제품의 제조원가가 높아지는 문제점이 따르고 있는 것이다.In addition, when the shape of the cross section is used in the reinforcement structure for maintaining the strength of the product, the structure of the manufacturing apparatus such as die is complicated, and the structure of the extrudate is not simple, resulting in low productivity due to the shrinkage change rate of the resin, as well as equipment cost. There is a problem that the cost is increased, and when inserting a separate reinforcing material in the filler is a problem that the manufacturing cost of the product is increased.

본 발명은 상기와 같은 사정을 고려하여 이루어진 것으로, 그 목적은 산업폐기물의 폐목을 보강재로 하는 판재를 일련의 기계적이고 자동적인 연속공정으로 제조시킬 수 있게 함으로써, 제조원가를 절감시키어 저렴한 가격으로 판재를 보급시킬 수 있는 판재의 제조장치를 제공하는 것이다.The present invention has been made in consideration of the above circumstances, and an object thereof is to allow a plate material of industrial waste wood to be reinforced as a reinforcing material to be manufactured in a series of mechanical and automatic continuous processes, thereby reducing manufacturing costs and reducing the cost of the plate. It is to provide an apparatus for manufacturing a plate that can be spread.

본 발명의 다른 목적은 제품의 충전재 밀도는 물론, 보강재가 장입유닛을 이용해 간헐적이고 연속적으로 충전재에 함침되게 함으로써, 그 장입밀도를 높이는 판재의 제조장치를 제공함에 있다. It is another object of the present invention to provide an apparatus for producing a plate material, which increases the loading density by allowing the reinforcing material to be impregnated into the filler intermittently and continuously using the charging unit as well as the filler density of the product.

본 발명의 또 다른 목적은 판재의 구조를 단순화하는 반면에 강도를 높이어 제품의 내구성은 물론 품질을 향상시킨 판재를 제공함에 있다.
Still another object of the present invention is to provide a plate that simplifies the structure of the plate while increasing the strength to improve the durability as well as the quality of the product.

도 2 및 도 3에는 본 발명에 따른 판재의 제조장치를 개략적으로 보이고 있는데, 본 발명 판재의 제조장치는 대략 크게 나누어 제1.2압출기(10,20)와 다이스유닛(60)과 장입유닛(70) 및 싸이징(30)과 냉각조(40), 그리고 인출수단(50)들을 연이어서 이루게 될 것이다.2 and 3 schematically show an apparatus for manufacturing a sheet according to the present invention, wherein the apparatus for manufacturing a sheet according to the present invention is roughly divided into the first and second extruders 10 and 20, the die unit 60 and the charging unit 70. And the sizing 30, the cooling bath 40, and the withdrawal means 50 will be made in succession.

이렇게 구성되는 판재의 제조장치에서 제1 및 제2압출기들(10,20)은 양측으로 병렬 배치되는데, 먼저 제1압출기(10)는 호퍼(11)를 통해 투입되는 분말 또는 과립상태의 수지 원료가 고열이 발생되는 스크루케이스(12)에서 발포과정을 이루어 그 헤드(13)와 연결관(14)을 통해 이후에 설명할 다이스유닛(60)의 제1다이스(62)로 충전재(4)의 용융물을 공급시게 될 것이다. 이때 충전재(4)는 산업폐기물인 폐합성수지를 이용하게될 것이다.The first and second extruders 10 and 20 are arranged in parallel to both sides in the apparatus for manufacturing a plate configured as described above. First, the first extruder 10 is a powder or granular resin raw material introduced through the hopper 11. Foaming process is performed in the screw case 12 in which high heat is generated, and through the head 13 and the connection pipe 14, the filler 4 of the filler 4 is formed into the first dice 62 of the die unit 60 which will be described later. The melt will be fed. In this case, the filler 4 will use waste synthetic resin, which is industrial waste.

또 제2압출기(20)는 호퍼(21)를 통해 투입되는 분말 또는 과립상태의 수지 원료가 고열이 발생되는 스크루케이스(22)를 통해 혼합 및 용융화 되어 그 헤드(23)와 연결관(24)을 통해 이후에 설명할 다이스유닛(60)의 제2다이스(64)로 외피(2)의 용융물을 공급시게 될 것이다In addition, the second extruder 20 mixes and melts the powder or granular resin raw material introduced through the hopper 21 through the screw case 22 in which high heat is generated, and the head 23 and the connection pipe 24.
