Description
본 발명은 곧은결무늬 원목단판 제조방법에 관한 것으로서, 더 상세하게는 일반 판목 형태의 목재판을 가공하여 곧은결무늬 원목단판을 제조하도록 구성함으로써, 원목에서 곧은결 판재를 제재하기 위한 작업의 불편함을 해소하는 것이 가능할 뿐만 아니라, 버리는 나무를 최소화하면서 폭이 넓은 정목 형태의 원목단판을 제조할 수 있는 곧은결무늬 원목단판 제조방법에 관한 것이다.The present invention relates to a method for manufacturing straight-grained log veneer, and more specifically, to a method for manufacturing straight-grained log veneer, which comprises manufacturing straight-grained log veneer by processing a general wood board, thereby eliminating the inconvenience of work for cutting straight-grained boards from logs, and also manufacturing wide, square-grained log veneer while minimizing the amount of wood wasted.
일반적으로 원목가구를 제작할 때 보통 제재목(sawn board)을 쓰게 되는데, 나무를 베어 통나무를 만들고 통나무를 제재기로 판재형태로 만든 것을 제재목이라 한다.When making wooden furniture, usually sawn boards are used. Sawn boards are made by cutting down a tree, making logs, and then using a saw to make boards out of the logs.
이때, 통나무를 어떤 패턴으로 잘라내는가에 따라 플레인쏜(plain sawn), 쿼터쏜(quarter sawn) 등의 이름을 갖는 판재가 만들어지는데, 플레인쏜(Plain sawn)은 가장 경제적으로 판재를 만들 수 있는 방식으로, 엔드그레인(end grain) 상의 나이테가 판재의 넓은면과 30도 이하의 각을 이루는 판재를 무늬결 판재라하고, 쿼터쏜(quarter sawn)은 통나무를 4등분한 상태에서 제재하는 것으로, 나이테와 판재의 넓은면의 만나는 각도가 60도에서 90도 사이인 판재를 곧은결 판재라 한다.At this time, depending on the pattern in which the log is cut, boards are made with names such as plain sawn and quarter sawn. Plain sawn is the most economical way to make boards, and boards in which the growth rings on the end grain form an angle of 30 degrees or less with the wide side of the board are called patterned grain boards, and quarter sawn is lumber made by cutting the log into four equal parts, and boards in which the angle between the growth rings and the wide side of the board is between 60 and 90 degrees are called straight grain boards.
상기와 같은 무늬결(판목) 판재를 제조하기 위한 선행기술이 공개특허 제10-1987-0002917호(이하, '특허문헌 1'이라 함.)에 개시되어 있다.A prior art for manufacturing a patterned wood board as described above is disclosed in Patent Publication No. 10-1987-0002917 (hereinafter referred to as “Patent Document 1”).

상기와 같은 구성으로 이루어진 특허문헌 2는 통상적인 원목을 통해 곧은결(정목) 판재를 제조하기 위한 것으로서, 곧은결(정목) 판재를 제조하기 위한 작업이 까다롭고 시간도 많이 소요될 뿐만 아니라, 폭도 좁고 버리는 나무가 많이 생기는 등 효율이 떨어짐에 따라 효율적으로 곧은결(정목) 판재를 제조하기 위한 방법이 요구되고 있다.Patent document 2, which consists of the above-mentioned configuration, is for manufacturing straight-grain (rectangular) boards using conventional raw wood. However, the work for manufacturing straight-grain (rectangular) boards is difficult and time-consuming, and the width is narrow and a lot of wood is wasted, resulting in low efficiency. Accordingly, a method for efficiently manufacturing straight-grain (rectangular) boards is required.

도 1 내지 5를 참조하면, 본 발명의 바람직한 실시예에 따른 곧은결무늬 원목단판 제조방법은, 먼저, 동일한 규격으로 이루어지는 일반 판목 형태의 목재판(100) 외면을 평평하게 대패질하여 외면 평탄화 작업을 수행하게 되는데, 이때, 목재판(100)은 집성목(300)을 형성함에 있어서, 다수의 커팅목재(200)간의 간격 조절을 결정하기 위해 도 1에 도시된 바와 같이, 다양한 두께 중 어느 하나의 목재판(100)을 사용하도록 구성된다.Referring to FIGS. 1 to 5, a method for manufacturing straight-grained wood veneer according to a preferred embodiment of the present invention first performs an outer surface flattening operation by flattening the outer surface of a general board-shaped wood plate (100) having the same specifications. At this time, the wood plate (100) is configured to use a wood plate (100) of any one of various thicknesses, as shown in FIG. 1, in order to determine the spacing between a plurality of cut wood pieces (200) when forming a laminated wood (300).
다음으로, 판재 모양이 곧은결 무늬가 되도록 세로톱을 이용하여 상기 목재판(100)을 길이방향을 따라 커팅하여 도 2에 도시된 바와 같은, 커팅목재(200)를 제조하게 되는데, 이때 목재판(100)의 커팅 간격에 따라 집성목(300)의 두께가 결정되며, 상기와 같이, 목재판 커팅단계를 통해 커팅된 다수의 커팅목재(200)에 대한 두께를 일정하게 맞추기 위한 샌딩작업을 진행한다. 상기 세로톱은 'ripsaw', 'gangripsaw' 등을 사용하는 것이 가능하다.Next, the wood board (100) is cut along the length direction using a vertical saw so that the board shape becomes a straight grain pattern, thereby manufacturing cut wood (200) as shown in Fig. 2. At this time, the thickness of the laminated wood (300) is determined according to the cutting interval of the wood board (100), and as described above, sanding work is performed to make the thickness of the plurality of cut woods (200) cut through the wood board cutting step consistent. The vertical saw can be a 'ripsaw', a 'gangripsaw', etc.
다음으로, 도 3에 도시된 바와 같이, 샌딩처리단계를 통해 두께가 일정하게 맞춰진 다수의 커팅목재(200)의 커팅면이 하늘을 향하도록 눕혀진 상태로 다수개의 커팅목재(200)를 나란히 위치시킨 후, 나란히 배열된 다수의 커팅목재(200)가 일체로 결합되도록 집성하여 집성목(300)을 구성하게 되는데, 다수의 커팅목재(200)를 집성시에는 형틀을 통해 배열된 다수의 커팅목재(200) 사이에 접착제를 주입하여 접착시키고, 형틀을 이용하여 다수의 커팅목재(200)가 일정한 형태로 조임 상태가 유지되면서 접착제의 고화가 완료되기까지 기다리게 되며, 접착체의 고화가 완료되면, 상기 목재집성단계를 통해 집성된 집성목(300)에 대한 두께를 일정하게 맞추기 위한 샌딩작업을 진행한다.Next, as illustrated in FIG. 3, a plurality of cut wood pieces (200) whose thicknesses are adjusted to a certain level through a sanding process are laid down so that their cutting surfaces face the sky, and then a plurality of cut wood pieces (200) arranged in a certain level are joined together to form a laminated wood (300). When gluing a plurality of cut wood pieces (200), an adhesive is injected between the arranged cut wood pieces (200) through a mold to bond them together, and the mold is used to tighten the plurality of cut wood pieces (200) into a certain shape, and the process is continued until the adhesive is completely hardened. When the adhesive is completely hardened, a sanding process is performed to adjust the thickness of the laminated wood (300) that is assembled through the wood gluing process to a certain level.
다음으로, 샌딩처리된 집성목(300)을 제작 사이즈에 맞도록 소정 규격으로 절단한 후, 도 4에 도시된 바와 같이, 절단된 집성목(300)의 하면에 자작합판(400)을 접착하게 되는데, 이때, 자작합판(400)의 하면에는 HPL(High Pressure Laminate)패널(500)이 추가로 접착될 수 있으며, 집성목 절단단계를 통해 소정 규격으로 절단된 또다른 집성목이 접착될 수 있다.Next, after the sanded laminated wood (300) is cut to a predetermined size to fit the production size, as shown in FIG. 4, a birch plywood (400) is bonded to the lower surface of the cut laminated wood (300). At this time, an HPL (High Pressure Laminate) panel (500) can be additionally bonded to the lower surface of the birch plywood (400), and another laminated wood cut to a predetermined size through the laminated wood cutting step can be bonded.
다음으로, 상기 합판접착단계를 통해 제작된 원목단판(600)에 대해 마감 규격에 따른 두께를 일정하게 맞추기 위한 샌딩작업을 진행한 후, 샌딩처리된 원목단판(600)을 마감 규격에 따른 사이즈에 맞도록 절단함으로써, 최종적으로 곧은결 무늬의 원목단판의 제조가 이루어지게 된다.Next, a sanding operation is performed on the raw wood veneer (600) manufactured through the above-mentioned plywood bonding step to ensure a consistent thickness according to the finishing specifications, and then the sanded raw wood veneer (600) is cut to a size according to the finishing specifications, thereby finally manufacturing a raw wood veneer with a straight grain pattern.
한편, 상기 원목단판(600)의 제조가 완료된 상태에서 다양한 심미감을 연출하기 위하여, 도 5에 도시된 바와 같이, 원목단판(600)의 상면 길이방향을 따라 일정간격 이격된 다수의 홈(610)이 형성되도록 가공할 수 있다.Meanwhile, in order to produce various aesthetic effects after the manufacture of the raw wood veneer (600) is completed, as shown in FIG. 5, a number of grooves (610) spaced at regular intervals along the longitudinal direction of the upper surface of the raw wood veneer (600) can be formed by processing.
본 발명은 전술한 바와 같이, 일반 판목 형태의 목재판(100)을 가공하여 곧은결무늬 원목단판(600)을 제조하도록 구성함으로써, 원목에서 곧은결 판재를 제재하기 위한 작업의 불편함을 해소하는 것이 가능할 뿐만 아니라, 버리는 나무를 최소화하면서 폭이 넓은 곧은결무늬(정목) 형태의 원목단판을 제조하는 것이 가능하다.As described above, the present invention is configured to manufacture a straight-grained wood veneer (600) by processing a general board-shaped wood board (100), thereby not only eliminating the inconvenience of the work of cutting straight-grained boards from logs, but also making it possible to manufacture a wide straight-grained (true wood) wood veneer while minimizing the amount of wood wasted.
