Description

폐플라스틱을 이용한 ３Ｄ프린터용 필라멘트 제조장치{MANUFACTURING DEVICE OF FILAMANT FOR 3D PRINTER USING WASTE PLASTICS}TECHNICAL FIELD [0001] The present invention relates to a filament manufacturing apparatus for a 3D printer using waste plastics,

본 발명은 폐플라스틱을 이용하여 3D프린터용 재료인 필라멘트를 제조하는 장치 및 방법에 대한 것이다.The present invention relates to an apparatus and a method for manufacturing a filament as a material for a 3D printer using waste plastics.

3D 프린터는 기업에서 어떤 물건을 제품화하기 전에 시제품을 만들기 위한 용도로 개발되었으나, 플라스틱 소재에 국한되었던 초기 단계에서 발전하여 나일론과 금속 소재로 범위가 확장되었고, 산업용 시제품뿐만 아니라 여러 방면에서 상용화 단계로 진입하였다.3D printers have been developed for the purpose of making prototypes before a product is commercialized by a company but have developed in the early stages of the process, limited to plastic materials, expanded to nylon and metal materials, .

일반적으로 입체 형태를 만드는 방식에 따라 크게 한 층씩 쌓아 올리는 적층형인 3D 프린터 방식(첨가형 또는 쾌속조형 방식)과 큰 덩어리를 깎아가는 절삭형 가공방식(컴퓨터 수치제어 조각 방식)으로 구분하며, 입체 형상의 대상물은 다양하게 결정될 수 있다.In general, it is divided into a 3D printer method (additive type or rapid prototyping method) and a cutting type machining method (computer numerically controlled engraving method) in which a large lump is cut by stacking up a layer by a method of forming a three-dimensional form. The object can be determined in various ways.

상기 적층형 방식으로는 FDM(;Fused Deposition Modeling)방식이 대표적이며, FFF(;Fused Filament Febrication)라고도 불리며 재료는 필라멘트라고 부르는 플라스틱 와이어를 사용한다.The FDM (Fused Deposition Modeling) method is typical in the laminated type, and is called a FFF (Fused Filament Fragment). A plastic wire called a filament is used as a material.

재료는 가열된 압출기를 통과하면서 용융이 되고 노즐을 통해 흘러나온 재료를 출력판에 적층하여 필요한 형상을 조형하는 방식으로 가정에서 접착용도로 사용하는 글루건과 방식이 유사하다.The material is similar to the glue gun used in home applications in the form of melting the melt while passing through a heated extruder and laminating the material flowing through the nozzle onto the output plate to shape the required shape.

이러한 3D 프린터의 재료는 상술한 것과 같이 필라멘트라고 불리는 얇은 플라스틱 실을 이용하며, 필라멘트를 녹여 아래에서부터 위로 층층히 쌓아가는 방식으로 구현되게 된다.The material of such a 3D printer is realized by using a thin plastic yarn called a filament as described above, and melting the filaments and stacking them from the bottom up.

이러한 필라멘트는 제조 회사별로 자체개발한 제품을 출시하여 상용화하고 있으며, 재료에 따른 그 품질이 상이하여 개별온도 조절을 해야 하는 등 매우 적용이 까다롭다.These filaments have been developed and commercialized by manufacturers, and the quality of the filaments is different according to the materials, so it is very difficult to apply individual temperature control.

특히, 우리나라의 경우에는 대부분 필라멘트 원료를 외국에서 수입하고 있는 실정으로, 저가의 필라멘트를 쉽게 구현할 수 있는 필요성이 커지고 있다.Especially, in Korea, most filament raw materials are imported from foreign countries. Therefore, there is a growing need to easily realize low cost filament.

도 1은 본 발명의 실시예에 따른 필라멘트 제조장치(이하, '본 제조장치'라 한다.)의 구성 블럭도이다. 도 2 내지 도 4는 도 1에 따른 요부 구성의 구성도이다. 도 5는 본 발명의 실시예에 따른 필라멘트 제조장치를 일 실시예로서 구현한 이미지이다.1 is a block diagram of a filament production apparatus (hereinafter referred to as a "production apparatus") according to an embodiment of the present invention. Fig. 2 to Fig. 4 are structural diagrams of the recessed portion configuration according to Fig. 5 is an image of a filament manufacturing apparatus according to an embodiment of the present invention.

도시된 도면을 참조하면, 도 1에 도시된 것과 같이, 본 제조장치는 세척수 또는 세척용액에 의해 세척된 폐플라스틱을 수용하는 폐플라스틱 원료공급유닛(100)과, 세척된 폐플라스틱 원료를 제공받아 파쇄하여 파쇄칩 형태로 구현하는 파쇄유닛(200), 상기 파쇄칩 형태의 재생원료를 공급받아 융융하고, 필라멘트로 압출하는 압출유닛(300) 및 상기 압출유닛(300)에서 제공되는 필라멘트를 권취하는 권취유닛(400)을 포함하여 구성될 수 있다.Referring to the drawings, as shown in FIG. 1, the present manufacturing apparatus includes a waste plastic raw material supply unit 100 for receiving waste plastic washed by wash water or cleaning solution, (300) for feeding the regenerated raw material in the form of a broken chip and melting the filament, and extruding the regenerated raw material into filaments, and a filament winding unit Up unit 400 as shown in FIG.

특히, 본 제조장치는 국내에서 폐기물로 버려지는 폐플라스틱병, 일예로 PET 병을 수거하여 이용할 수 있으며, 이러한 PET 병과 같은 폐플라스틱을 파쇄 및 세정, 그리고 용융 및 압축하여 3D프린터용 재료인 필라멘트 구조로 구현할 수 있도록 할 수 있다. 본 제조장치에 적용될 수 있는 폐플라스틱의 재료로는 ABS(acrylonitrile-butadiene-styrene resin), PLA(PolyLactic Acid), PET, Nylon, PC(polycarbonate), PVA(Polyvinyl Alcohol), HIPS(High-Impact Polystyrene), wood, TPU(Thermoplastic polyurethane) 등 선택되는 것들을 적용할 수 있다. 그러나 원료의 특성이 각기 상이하고, 물에 녹는 특징이나 기포 발생이 많아지는 점 등의 특수성을 고려하여, 본 발명의 실시예에서는 PET를 재료로 하여 필라멘트를 제조하는 것을 일 실시예로 하여 설명하기로 한다.In particular, the present manufacturing apparatus can collect and use waste plastic bottles, such as PET bottles, which are thrown away as waste in the domestic market. The waste plastics such as PET bottles are crushed, cleaned, melted and compressed to form filament structures As shown in FIG. Polycarbonate (PVA), polyvinyl alcohol (PVA), and high-impact polystyrene (HIPS) are used as the materials of the waste plastics that can be applied to the present manufacturing apparatuses, such as ABS (acrylonitrile-butadiene-styrene resin), PLA ), wood, thermoplastic polyurethane (TPU), and the like. However, in the embodiment of the present invention, the filament is manufactured using PET as a raw material in consideration of the characteristics such as the characteristics of the raw materials, the characteristic of melting in water or the generation of bubbles, etc., .

상기 원료공급유닛(100)은, 도 1에 도시된 것과 같이, 원료세척유닛(10)을 포함하는 구조로 구현할 수 있다. 상기 원료세척유닛(10)은 폐플라스틱에 대해 세척수를 분사하여 외표면의 이물질을 제거하는 세척부(110), 세척수에 제거된 이물질을 분리하여 배출하는 제1필터부(120), 1차세척된 폐플라스틱을 건조하는 제1건조부(130), 건조된 폐플라스틱을 수용하고, 상기 파쇄유닛으로 전달하는 로딩부(140)를 포함하여 구성될 수 있다.The raw material supply unit 100 may be implemented in a structure including the raw material cleaning unit 10, as shown in FIG. The raw material cleaning unit 10 includes a cleaning unit 110 for spraying cleaning water on waste plastics to remove foreign substances on the outer surface, a first filter unit 120 for separating and discharging the foreign substances removed in the cleaning water, A first drying unit 130 for drying the waste plastic, and a loading unit 140 for receiving the dried waste plastic and delivering the waste plastic to the shredding unit.

상술한 것과 같이, 본 제조장치에서 원료로 사용하는 원재료는 PET병과 같은 폐기물인바, 외부 표면에 오염물질이 묻거나, 병 자체의 표면에 상표라벨이나 코팅재 등 PET와는 다른 재질의 원료를 포함하는 경우가 대부분이다. 상기 원료세척유닛(10)에서는 이러한 이물질을 1차적으로 제거하는 기능을 수행한다. 소규모의 제조장치에서는 도 5와 같이 장치와 연결되는 구조로 구현하는 것이 가능하나, 일반적으로는 도 5의 장치와 연속공정으로 처리하기 위해, 도 7a와 같은 구조에서 별도의 세척공정을 위한 세척라인 구조로 구현할 수 있도록 하는 것도 가능하다.As described above, if raw materials used as raw materials in the present manufacturing apparatus are wastes such as PET bottles, contaminants are adhered to the outer surface, and the surface of the bottle itself contains raw materials other than PET, such as brand labels and coating materials . The raw material cleaning unit 10 performs a function of primarily removing such foreign matter. In a small-sized manufacturing apparatus, it is possible to implement a structure connected to the apparatus as shown in FIG. 5. Generally, in order to process the apparatus and the continuous process of FIG. 5, It is also possible to implement it in a structure.

상기 원료공급유닛(100)에서 세척되는 폐플라스틱은 본 제조장치에서는 파쇄된 형태로 가공될 수 있도록 한다. 이는 폐플라스틱 자체의 크기로는 압출의 공정이 어려우며, 보다 작은 온도와 열원으로 용융이 가능하도록 하며, 압출의 공정을 용이하게 하기 위해 파쇄유닛(200)을 통해 잘게 절단하여 파쇄칩 형태로 구현할 수 있도록 한다.The waste plastic to be cleaned in the raw material supply unit 100 can be processed into a crushed form in the present manufacturing apparatus. This is because the waste plastic itself is difficult to extrude and can be melted with a smaller temperature and a heat source and can be finely cut through the shredding unit 200 to facilitate the process of extrusion, .

이러한 상기 파쇄유닛(200)은, 도 2에 도시된 것과 같이 상기 원료공급유닛(100)에서 세척 처리된 폐플라스틱을 파쇄하는 커팅부(210)와 상기 폐플라스틱 또는 파쇄된 파쇄 플라스틱을 교반시키는 교반부(220), 상기 교반부에서 유동하는 파쇄플라스틱과 혼합되어 있는 이물질을 중량차 또는 직경차이를 이용하여 풍압 또는 필터망을 통해 분리하는 필터부(230), 상기 필터부(230)에서 분리된 이물질을 배출하는 제1배출부(240)를 포함하여 구성될 수 있도록 할 수 있다.2, the shredding unit 200 includes a cutting unit 210 for shredding the waste plastic that has been cleaned in the raw material supply unit 100, and agitation for stirring the waste plastic or shredded plastic A filter unit 230 for separating impurities mixed with the crushing plastic flowing through the agitating unit through a wind pressure or a filter net using a weight difference or a diameter difference, And a first discharge unit 240 for discharging foreign matter.

파쇄된 결과물은 도 7b에 도시된 이미지와 같이 파쇄 칩 형태로 구현될 수 있도록 절단커터를 구비한 커팅부에서 파쇄를 하게 된다. 상기 커팅부는 절단커터를 고속으로 회전하는 방식이나 압축후 일정한 단위 사이즈로 압축 절단하는 방식 등 공지의 절단 방식을 채용할 수 있다. The shredded product is crushed in a cutting portion provided with a cutting cutter so that it can be implemented in the form of a broken chip as shown in the image shown in FIG. 7B.
