본 발명은 열선을 이용하여 스티로폼 등 판재재료(1)를 한층씩 가공하고 가공된 단위층을 한층씩 쌓아올려 삼차원 임의형상의 제품을 조형하는 데 사용되는 열선가공기에 있어서 판재재료(1)의 두께에 상관없이 열선의 중심이 항상 판재재료(1)의 두께방향 중앙면(23)상에 위하도록 판재재료(1)를 파지하기 위한 열선가공기의 재료파지기구에 관한 것이다.According to the present invention, the thickness of the plate material (1) in a hot wire processing machine used to form a three-dimensional arbitrary shape product by processing a sheet material (1) such as styrofoam one by one using a hot wire and stacking the processed unit layer one by one The material holding mechanism of the hot wire processing machine for holding the plate material 1 so that the center of the hot wire is always on the thickness direction central surface 23 of the plate material 1 irrespective of the above.

일반적으로 열선가공기는 도3에 나타난 바와 같이 좌우상하로 움직이는 XY테이블(22) 상에 평행사변형 기구(21)로 구성된 열선뭉치(18)를 설치하여 열선 뭉치(18)의 끝단에 설치된 열선(19)을 x 및 y방향으로 회전하면서 스티로폼 등 판 재재료(1)를 임의 형상으로 측면에 경사를 주어 가공하는 장치이다. 여기서 평행사변형기구(21)에 설치된 열선(19)은 평행사변형 기구(21)에 의해 열선중심(20)을 기준으로 회전하게 되어 있어 두께를 가진 판재재료(1)에 측면경사각을 주어 가공할 수 있는 것이다. 이를 위해서는 가공하고자하는 스티로폼 등 판재재료(1)를 두께방향의 중앙면(23)이 열선 중심(20)을 지나도록 장착해야 하며 이를 벗어나면 가공된 단위층의 치수정밀도 악화되는 문제를 초래하게 된다. In general, the hot wire processing machine is provided with a heating wire bundle 18 composed of parallelogram mechanisms 21 on the XY table 22 moving left and right, as shown in FIG. ) Is an apparatus for processing a sheet material such as styrofoam inclined to the side in an arbitrary shape while rotating in the x and y directions. Here, the heating wire 19 installed in the parallelogram mechanism 21 is rotated based on the heat ray center 20 by the parallelogram mechanism 21, so that the sheet material 1 having a thickness can be machined by giving a side inclination angle. It is. To this end, the plate material 1 such as styrofoam to be processed should be mounted so that the central surface 23 in the thickness direction passes through the center of the hot wire 20, and if it is out of this, the dimensional accuracy of the processed unit layer is deteriorated. .

도1과 도2에서 보는 바와 같은 종래의 재료파지기구는 고정된 재료고정구(25)에 스티로폼 등 판재재료(1)가 밀착되도록 되어 있어 판재재료(1)의 두께가 변하면 판재재료(1)의 중앙면(23)이 열선 중심(20)을 벗어나게 되어 원하는 형상의 단위층을 가공할 수 없는 문제점이 있다. 이러한 문제점을 해결하려면 열선뭉치(18)의 위치를 조절하거나 재료고정구(25)의 위치를 조절하여야 하는 데 판재재료(1)의 두께가 수시로 바뀌는 경우에는 그때마다 조정해주어야 하는 불편이 따를 뿐만아니라 위치조정에 많은 시간이 소요되고 일반사용자가 사용하기에는 정밀조정이 사실상 곤란하다. In the conventional material holding mechanism as shown in Figs. 1 and 2, the plate material 1 such as styrofoam is brought into close contact with the fixed material fixing tool 25 so that the plate material 1 is changed when the thickness of the plate material 1 changes. The central surface 23 is out of the center of the hot wire 20 has a problem that can not process the unit layer of the desired shape. In order to solve this problem, it is necessary to adjust the position of the bundle of heat wires 18 or adjust the position of the material fixing tool 25, but if the thickness of the plate material 1 changes from time to time, as well as the inconvenience that must be adjusted every time It takes a lot of time to make adjustments and it is virtually difficult for the general user to use them.

따라서, 본 발명은 상기의 제반 문제점을 해결하기 위하여 안출된 것으로서, 좌우에서 서로 대향지게 상하로 움직이는 두쌍의 상하 파지판(2,3,4,5)이 모터(31)에 의해 회전하는 연동축(16)의 회전에 따라 각쌍의 파지판(2,3/4,5)의 중간에 장착된 판재재료(1)를 두께에 상관없이 일정한 위치에서 파지하도록 함으로써 가공하고자하는 판재재료(1)의 중앙면(23)이 항상 열선 중심(20)을 지나도록 파지하는 열 선가공기의 재료파지기구를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the above problems, the two shafts of the upper and lower holding plates (2, 3, 4, 5) moving up and down to face each other from side to side rotated by the motor 31 The plate material 1 to be processed is held by holding the plate material 1 mounted in the middle of each pair of holding plates 2, 3/4, and 5 at a predetermined position regardless of thickness as the rotation of the 16 is performed. It is an object of the present invention to provide a material gripping mechanism of a hot wire processing machine which grips the center surface 23 to always pass through the hot wire center 20.

Each pair of grip plates 2,3 / 4,5 are installed in close contact with each other on a horizontal plane 24 passing through the hot wire center 20, and the motor 31 is rotated to hold each pair of grip plates 2,3 /. 4,5) are spaced apart. At this time, since the drive pulleys 6 and 7 are interlocked by the interlocking shaft 16, it is apparent that the pair of holding plates 2, 3/4 and 5 are spaced at the same interval. After the material is placed on the material stage 30 by a manual or automatic method between the spaced gripping plates 2, 3/4, 5, the gap between each pair of gripping plates 2, 3/4, 5 is narrowed. When the motor 31 is rotated so that the pair of holding plates 2, 3/4, 5 approach each other, the guide pins 14, 15 provided on the lower holding plates 3, 5 are connected to each other. Inserted into the hole 28 to lift the plate material (1) mounted on the material stage 30 and when the upper surface of the plate material (1) is in contact with the upper holding plate (2, 4) material detection sensor 29 Is activated to stop the motor 31. In this case, each pair of holding plates 2, 3/4, 5 are spaced apart from each other by the thickness of the material, and as shown in FIG. 5C, the center surface 23 of the sheet material 1 is always positioned at the center of the heating wire 20. will be. On the contrary, after the hot wire processing is completed, the plate material 1 is positioned on the material stage 30 and released by rotating the motor 31 in reverse to separate the upper and lower holding plates 2, 3/4, and 5 from each other. .
