본 발명은 폐합성수지와 목재의 칩을 이용한 파레트 제조방법 및 이에 의해 제조된 파레트에 관한 것으로, 보다 상세하게는 재생이 불가능한 폐합성수지를 수거하여 목재의 칩(일명 '톱밥')과 적절하게 혼합하여 파레트를 성형함으로써, 내구성을 얻을 수 있어 파레트의 비틀림이 예방되고, 특히 재생 불가능한 자원을 재활용할 수 있으므로 자원의 절약은 물론 그로 인해 제조단가를 줄일 수 있고, 소비자 가격이 줄어들어 경제성이 있는 파레트를 얻고자 하는 것이다.The present invention relates to a method for producing a pallet using waste synthetic resin and wood chips, and to a pallet produced by the present invention. More specifically, it is possible to collect waste synthetic resins that cannot be recycled and to properly mix with chips of wood (aka 'sawdust'). By molding the pallets, durability can be obtained, which prevents the torsion of the pallets, and in particular, recycling non-renewable resources, which not only saves resources, but also reduces manufacturing costs and reduces consumer prices, resulting in economical pallets. I will.
일반적으로 하중이 많이 나가는 다량의 제품을 적재하거나 운반할 때 적재물의 안전을 위해 파레트를 사용하는 것은 이미 보편화된 방법으로, 물적 유통의 단가를 절감하는 수단으로 급속하게 발전하고 있으며, 상기 파레트는 다방면에 상용화된 것으로 각 공장, 창고 작업장에서 많이 사용되고 있으며, 특히 수출상품의 물건을 보호하는 수단으로 본격적으로 활용되어 지고 있다.In general, the use of pallets for the safety of loads when loading or transporting a large amount of heavy loads is already a common method, which is rapidly developing as a means of reducing the unit price of physical distribution. It is commercially used in many factories and warehouses, and is used in earnest as a means of protecting the goods of export goods.
상기 파레트로는 합성수지 파레트, 보드 파레트, 목재 파레트, 합판 파레트, 철재 파레트 등이 많이 사용되어 지고 있는데, 이러한 기존의 파레트들은 가격대가 상당히 고가이어서 이를 사용하고자 하는 경우 비용상의 부담이 가중되어 경제성이 떨어지게 되고, 장시간 사용에 의해 노후되거나 외부의 충격으로 인해 파손되어 더 이상 사용할 수 없게 되어 폐기 처분될 때 처분에 따른 인력비용이 소모되며, 재활용을 할 수 없어 환경상의 문제점이 있어 왔다.The pallet is a lot of synthetic pallets, board pallets, wooden pallets, plywood pallets, steel pallets, etc., these conventional pallets are quite expensive, so if you want to use them, the cost burden is added to the economical efficiency is reduced And, due to long-term use or damaged by an external shock can not be used anymore when disposed of waste manpower costs due to disposal, there is an environmental problem can not be recycled.
상기와 같이 종래의 파레트로 인한 문제점을 해결하기 위하여 종이 파레트가 최근에 각광받아 널리 사용되어 지고 있는데, 이 또한 목재 또는 합성수지 파레트의 단점을 일부 해소하기는 하지만 내구성이 크게 떨어져 비틀림현상 때문에 장시간 사용할 수 없게 되어 사용상의 불편함이 있는 문제점이 있다.In order to solve the problems caused by the conventional pallets, paper pallets have recently been widely used and widely used. This also solves some of the disadvantages of the wooden or synthetic pallets, but the durability is greatly reduced, so they can be used for a long time. There is a problem that there is inconvenience in use.
본 발명은 상기의 종래 문제점을 해결하기 위해 안출한 것으로, 폐합성수지와 목재의 칩을 적절하게 혼합하여 파레트를 성형할 수 있도록 함으로써, 습기 등에 장시간 노출되어도 파레트의 비틀림이 없어 내구성이 우수하고, 재생 불가능한 자원을 재활용할 수 있어 자원의 절약은 물론이거니와 파레트의 폐기 처분에 따른 환경상의 문제점을 해결하도록 하는데 목적이 있다.The present invention has been made to solve the above-mentioned conventional problems, and by mixing the waste synthetic resin and the chip of the wood properly to form a pallet, there is no torsion of the pallet even if exposed to moisture for a long time, excellent durability, regeneration The purpose is to save resources by recycling impossible resources and to solve environmental problems caused by the disposal of pallets.
상기의 목적을 달성하기 위하여 용융기에 폐합성수지와 목재의 칩을 7:3의 중량비로 혼합하여 250℃에서 5분 동안 용융하는 제1공정; 상기 제1공정에서 얻어진 혼합물을 롤링머신을 이용하여 소정의 두께로 롤링하는 제2공정; 부드러운 박판으로 구성되어진 혼합물을 파레트의 성형기에 투입하여 압착하여서 파레트로 성형하는 제3공정; 이를 서서히 냉각 건조시켜 굳게 하는 제4공정;으로 이루어지는 폐합성수지와 목재의 칩을 이용한 파레트의 제조방법 및 이에 의해 제조된 파레트를 구현하고자 한 것이다.In order to achieve the above object, a first step of mixing the waste synthetic resin and wood chips in a melter in a weight ratio of 7: 3 to melt for 5 minutes at 250 ℃; A second step of rolling the mixture obtained in the first step to a predetermined thickness using a rolling machine; A third step of molding the mixture consisting of a soft thin plate into a pallet forming machine and pressing the mixture to form the pallet; It is intended to implement a method for producing a pallet using a waste synthetic resin and wood chips consisting of a fourth step of stiffening by cooling and drying it gradually, and a pallet prepared by this.
이하, 도면을 참조하여 본 발명에 적용되는 폐합성수지와 목재의 칩을 이용한 파레트 제조방법 및 이에 의해 제조된 파레트에 대하여 상세히 설명한다.Hereinafter, with reference to the drawings will be described in detail a pallet production method and a pallet produced by using the waste synthetic resin and wood chips applied to the present invention.
도1은 본 발명에 의해 구현된 파레트(1)의 사시도이고, 도2는 파레트(2)의 단면도이다.1 is a perspective view of a
도시된 바와 같이 본 발명에 의해 제조된 폐합성수지와 목재의 칩이 적절하게 혼합된 파레트(1)는 표면상에 다수개의 요입부(10)를 일정 간격으로 배치되어 형성되며, 하부에는 상기 요입부(10)를 형성하면서 파레트(1)를 지지하는 받침대(20)를 형성하여 구성한다.As shown, the
본 발명에 의한 파레트(1)가 폐합성수지와 목재의 칩이 적절하게 혼합되어 제조되는 과정을 살펴보면, 다음과 같다.Looking at the process of the pallet (1) according to the present invention is manufactured by mixing the waste synthetic resin and wood chips appropriately, as follows.
[제1공정][Step 1]
먼저 폐합성수지에서 재생 불가능한 수지만을 수거하고, 그후 용융기에 수거한 폐합성수지와 목재의 칩을 7:3의 중량비로 혼합하여 투입한 후 150∼250℃에서 2∼5분 정도 용융한다.First, only non-renewable resin is collected from the waste synthetic resin. Then, the waste synthetic resin and wood chips collected in the melter are mixed and added in a weight ratio of 7: 3, and then melted at 150 to 250 ° C. for 2 to 5 minutes.
상기 공정에서 사용되는 폐합성수지는 일반적인 합성폐기물에서 솜, 면 등이 포함된 낡은 비닐 등의 재생이 불가능한 합성수지만을 수집하여 이를 재활용한다는 것이다.The waste synthetic resin used in the process collects and recycles only non-renewable synthetic resin such as old vinyl including cotton and cotton from general synthetic waste.
그리고 목재의 칩은 소재를 목재하고 이를 미세한 분말로 형성하거나 아니면 톱밥, 완겨 등을 이용해도 된다.Wood chips can be made of wood and formed into fine powder, or they can be made from sawdust or wedges.
위 혼합비율은 최대 8:2∼5:5의 중량비율로 하여도 본 발명에서의 소기의 목적을 달성할 수 있지만, 7:3의 중량비율로 혼합하는 것이 가장 적절하며, 이는 응고에 따른 시간이 단축될 수 있을 뿐만 아니라 내구성이 가장 뛰어난 혼합비율이기 때문이다. 특히, 목재의 칩을 3의 중량비로 하였을 때 폐합성수지의 7의 중량비에서는 P.P를 3으로 하고, P.E를 4로 하는 것이 상기에서 언급한 바와 같이 응고가 빠를 뿐만 아니라 내구성이 가장 우수하다.Although the above mixing ratio can achieve the desired purpose in the present invention even at a weight ratio of 8: 2 to 5: 5, it is most suitable to mix at a weight ratio of 7: 3, which is time according to solidification. Not only can this be shortened, but also because the mixing ratio is the most durable. Particularly, when the wood chips have a weight ratio of 3, in the weight ratio of 7 of the waste synthetic resin, the P.P and the P.E are 4, as mentioned above.
상기 용융온도는 칩의 소재가 목재이기 때문에 그 이상의 온도가 되면 목재의 칩이 타게 되고, 그 이하는 합성수지와 목재칩의 혼합물의 용융에 있어서 용융이 잘 이루어지지 않는다. 따라서 위 온도의 경우가 합성수지와 목재의 칩이 혼합되어 용융이 가장 적절하다. Since the melting temperature of the chip material is wood, if the temperature is higher than the chip of the wood is burned, the melting is less than the melting of the mixture of synthetic resin and wood chips. Therefore, in the case of the above temperature, the melting of the synthetic resin and wood chips is most suitable.
[제2공정][Step 2]
상기 제1공정에서 얻어진 혼합물을 롤링머신을 이용하여 소정의 두께로 롤링 한다. The mixture obtained in the first step is rolled to a predetermined thickness using a rolling machine.
용융기에서 폐합성수지와 목재의 칩이 혼합되어 얻어진 혼합물은 젤처럼 말랑말랑한 상태이고, 이를 통상의 롤링머신에 투입하여 10∼20㎜의 두께를 갖도록 박판을 성형한다.The mixture obtained by mixing the waste synthetic resin and wood chips in the melter is in a soft state like a gel, and is put into a conventional rolling machine to form a thin plate to have a thickness of 10 to 20 mm.
[제3공정][Step 3]
부드러운 박판으로 구성되어진 혼합물을 도시된 바와 같은 형상을 갖는 금형을 장착한 파레트의 성형기에 투입한 후, 압착하여서 도면과 같은 형상의 파레트로 성형한다.The mixture composed of the soft thin plates is put into a molding machine of a pallet equipped with a mold having a shape as shown, and then compressed into a pallet having a shape as shown in the drawing.
도면에 도시된 바와 같은 형상으로 이루어진 파레트를 성형하기 위한 성형기는 대략 약 1000ton 정도를 유지하여야 만이 파레트의 형상으로 성형할 수 있다. A molding machine for molding a pallet having a shape as shown in the drawings may be molded in the shape of a pallet only by maintaining approximately 1000 tons.
[제4공정][Step 4]
성형기에 의해 성형된 성형물(파레트)를 성형하는 과정에나 성형을 한 후에 서서히 냉각 건조시켜 굳게 한다.In the process of molding the molded product (part) by the molding machine or after molding, it is gradually cooled and dried to harden.
상기 제3공정에서 얻어진 성형물을 자연 또는 강제(수냉 또는 공냉)로 서서히 냉각시킴으로써 본 발명의 제품을 완성하게 된다.The product of the present invention is completed by gradually cooling the molded product obtained in the third step by natural or forced (water cooling or air cooling).
이상과 같이 본 발명은 재생이 불가능한 폐합성수지와 목재의 칩을 적절하게 혼합하여 파레트를 성형할 수 있도록 한 것으로, 이상에서 설명한 본 발명은, 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자에 있어 본 발명의 기술적 사상을 벗어나지 않는 범위내에서 여러 가지 치환, 변형 및 변경이 가능하므로 전술한 실시례 및 첨부된 도면에 한정되는 것이 아니다.As described above, the present invention enables to form a pallet by appropriately mixing a non-recyclable waste synthetic resin and a chip of wood, and the present invention described above is suitable for those skilled in the art. Therefore, various substitutions, modifications, and changes are possible without departing from the technical spirit of the present invention, which is not limited to the above-described embodiments and the accompanying drawings.
본 발명은 재생불가능한 폐합성수지를 이용하여 파레트를 성형하되, 목재의 칩을 적정량 혼합하여 제조할 수 있도록 함으로써, 습기나 실외에 장시간 노출되어도 파레트 자체의 비틀림 현상이 발생하지 않아 내구성이 우수하며, 무게가 가벼워 사용상의 편의성이 향상되고, 재생불가능한 폐합성수지를 이용하여 파레트를 제조하여 자원의 재활용을 통한 경제성이 뛰어나며, 폐합성수지의 폐기 처분에 따른 대기 및 토양오염을 방지할 수 있어 환경친화적인 효과가 있다.The present invention is to form a pallet using a non-recyclable waste synthetic resin, but by mixing a suitable amount of wood chips, even if exposed to moisture or outdoors for a long time does not cause the torsion of the pallet itself, excellent durability, weight Its light weight improves the convenience of use, manufactures pallets using non-recyclable waste synthetic resins, and provides excellent economic efficiency through recycling of resources.
