본 고안은 필름 연신장치중 니핑(Nipping)로울러의 승강장치에 관한 것으로, 보다 상세하게는 슬라이드브라켓에 직선운동가이드 베어링을 설치하고, 지지브라켓에 가이드레일을 설치하여서 니핑로울러승강이 정확하고 신속하게 이루어지게한 필름연신장치의 니핑 로울러 승강장치에 관한 것이다.The present invention relates to a lifting device of the nipping roller of the film drawing device, and more specifically, the linear movement guide bearing is installed on the slide bracket, and the guide rail is installed on the support bracket, so that the lifting and lifting of the nipping roller is made accurately and quickly. The present invention relates to a nipping roller elevating device for a stretched film stretching device.
본 고안에서 플라스틱 필름이라하면 각종 포장용, 사진용, 정보기록매체용 전기재료용 등과 같은 용도를 만들기 위한 절단전의 플라스틱 필름이며, 필름이송장치는 상기의 필름을 각종수단의 장치를 이용하여 연신 및 권취하기 위하여 로울러를 이용하여 이송시켜 최종 소비자가 원하는 용도로 제품화시키는 장치를 말한다.In the present invention, the plastic film is a plastic film before cutting to make a variety of applications such as packaging, photography, information recording media, electrical materials, and the like, and the film transfer device draws and winds the above film using various means. In order to convey by using a roller in order to produce a product for the end consumer desired.
이러한 필름이송장치의 전체적인 개략구성도가 제1도에 도시된 바, 도면부호10은 필름, 12 내지 19는 고정 로울러, 20은 로울러 지지브라켓, 21과 22는 니핑로울러를 나타내고, 필름(10)은 상기한 도면의 우측로울러(12) 즉, 필름의 진행방향에서 좌측로울러(19)까지 이송되어 지나가며, 특히 중앙의 두 고정로울러(16,17)에 대해 이 로울러(16,17)와 수직으로 접촉되는 니핑로울러(21,22)와의 사이로 이송되는 과정을 거치게 된다.The overall schematic configuration of such a film transfer device is shown in FIG. 1, reference numeral 10 denotes a film, 12 to 19 a fixed roller, 20 a roller support bracket, 21 and 22 a nipping roller, and a film 10 Is conveyed to the right roller 12 in the drawing, that is, to the left roller 19 in the advancing direction of the film, in particular perpendicular to the two rollers 16, 17 in the center. It is subjected to the process of transporting between the nipping roller (21, 22) in contact with.
그 사이에 끼어있는 상기한 필름(10)이 물려진 상태로 있게 되고, 그 다음의 고정로울러(17)도 니핑로울러(22)가 맞닿아 필름(10)이 그 사이에 끼인채로 회전되지만, 이들 뒷쪽 로울러(17,22)가 상기한 앞쪽 로울러(16,21)보다 다소 빠르게 회전된다면 이송되던 필름(10)은 이들 로울러(16,21 및 17,22) 사이에서 강제로 눌리어서 종방향(필름의 이송진행방향) 이송으로 연속적으로 다음 로울러(17)로 이송되어지게 되는 것이다.The film 10 sandwiched therebetween is left in the bite state, and the next fixed roller 17 also rotates while the nipping roller 22 abuts and the film 10 is sandwiched therebetween. If the rear rollers 17, 22 are rotated somewhat faster than the front rollers 16, 21 described above, the film 10 that has been conveyed is forcibly pressed between these rollers 16, 21, and 17, 22 in the longitudinal direction (film). The feed progress direction of) will be conveyed to the next roller 17 continuously.
따라서, 상기한 니핑로울러(21,22)는 고정로울러(16,17)에 접촉되었다가 떨어지는 구동방식으로 작동되게 되는데 이를 위한 종래의 니핑로울러 승강장치는 제2도에 도시된 바와 같다.Therefore, the nipping rollers 21 and 22 are operated in a driving manner in contact with the fixed rollers 16 and 17, and the conventional nipping roller lifting apparatus is shown in FIG.
즉, 凹자형의 지지브라켓(20)에 H자형의 슬라이드브라켓(24)이 승강되게 조립되고, 이 슬라이드브라켓(24)에 니핑로울러(21 혹은 22)가 설치되어서, 슬라이드브라켓(24)이 승강됨에 따라 상기한 니핑로울러(21 혹은 22)가 동시에 승강되어져 상기한 필름(10)을 잡아주어 수평력을 주게 되는 것이다.That is, the H-shaped slide bracket 24 is assembled to the U-shaped support bracket 20 so that the slide bracket 24 is provided with a nipping roller 21 or 22 so that the slide bracket 24 is elevated. As the nipping rollers 21 or 22 are lifted at the same time to hold the film 10 to give a horizontal force.
그런데 상기한 바와 같이 종래의 니핑로울러(21,22)를 승강시키는 수단은 지지브라켓(20)에 슬라이드브라켓(24)이 A와 a 및 A'와 a' 부분의 공차와 B와 b및 B'와 b' 부분의 공차에 의해서 상하로 슬라이딩 됨에 따라 양접촉면의 잦은 마찰에 의해 마모 및 마멸이 생기게 되고 이로 인하여 과부하로 작동이 불안정한 단점이 있어 왔다.However, as described above, the conventional means for raising and lowering the nipping rollers 21 and 22 includes a tolerance of the A and a and A 'and a' portions of the support bracket 20 and the B and b and B '. Sliding up and down due to the tolerance of and b 'portion wear and wear is caused by frequent friction of the contact surface has been a disadvantage that the operation is unstable due to overload.
또한, A와 a 및 A'와 a' 부분의 공차만큼 니핑로울러(21,22)의 밴딩(BANDING)현상이 발생되어 로울러의 좌우측 방향으로 틀어짐 현상으로 고정로울러와의 틈새가 발생되어 니핑불량상태가 되고, B와 b 및 B'와 b' 면의 공차발생으로 고정로울러(16,17)와 중심이 불일치되며, 따라서 니핑로울러 전폭에 균일한 니핑작동이 이루어지지 않아 공정이 불안정하여 제품의 겹침현상 및 주름이 발생되어 품질에 매우 부정적인 영향을 주게 된다.In addition, a banding phenomenon of the nipping rollers 21 and 22 occurs by the tolerances of A, a and A 'and a', and the gap between the fixed roller is generated due to the phenomenon of twisting in the left and right directions of the rollers. Due to tolerances of B and b and B 'and b' planes, the center of the fixed rollers (16, 17) is inconsistent with the center of the rollers. The phenomenon and wrinkles are generated, which has a very negative effect on the quality.
이에 본 고안에서는 상기한 니핑 로울러의 승강동작이 원활하게 이루어지도록 그 구조를 개선시킨 것이다.Therefore, the present invention is to improve the structure so that the lifting operation of the nipping roller described above is made smoothly.
이를 위해 지지브라켓의 양 수직대 뒷면에 가이드레일을 설치하고, 이 가이드레일에 직선운동가이드 베어링이 슬라이딩되게 접촉되도록 슬라이드브라켓에 베어링 지지부를 형성시켜서 베어링이 가이드 레일에 의지하여 슬라이딩됨에 따라 승강시에 마찰이 극소화되어짐은 물론, 승강동작이 정확하고 유격(공차)이 없어서 신속하고 정확한 필름연신작업이 이루어지게 한 것이다.To this end, guide rails are installed on the back of both vertical brackets of the support bracket, and the bearing support is formed on the slide bracket so that the linear motion guide bearings slide in contact with the guide rails. Not only is the friction minimized, but the lifting operation is accurate and there is no play (tolerance), so that the film stretching work can be done quickly and accurately.
이하, 첨부도면을 참고하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 니핑로울러(21 혹은 22)가 지지되는 슬라이드브라켓(32)에 베어링 설치부(38)를 형성시키고, 이 베어링 설치부(38)에 직선운동 가이드용 베어링(36)을 설치하며, 지지브라켓(20)의 슬라이드홈(23)을 구성하는 양수직대(24,26) 뒷면 모서리에 가이드레일(31)을 형성시켜서, 상기 베어링(36)이 가이드레일(31)을 따라 승강되어짐에 따라 슬라이드브라켓(32)이 지지브라켓(20)에 마찰없이 승강되도록 구성시킨 필름연신장치의 니핑로울러 승강장치이다.The present invention forms a bearing mounting portion 38 on the slide bracket 32 on which the nipping rollers 21 or 22 are supported, and installs a bearing 36 for linear motion guide in the bearing mounting portion 38, and supports Guide rails 31 are formed on the rear edges of the pumping poles 24 and 26 constituting the slide grooves 23 of the bracket 20 so that the bearings 36 are raised and lowered along the guide rails 31. It is a nipping roller elevating device of the film drawing device configured to raise and lower the bracket 32 without friction to the support bracket (20).
제3도는 본 고안의 지지브라켓(20)에 대한 구성도로, 이하에는 종래의 필름연신장치에서 사용되는 고정로울러(16 혹은 17)에 니핑로울러(21 혹은 22)가 수직승강되는 브라켓이며, 승강원리나 구조가 같으므로 일측 로울러(16과 21)로 승강되는 구성과 동작을 설명하여 타측로울러(17과 22)에 함께 적용시키도록 한다.3 is a configuration diagram for the support bracket 20 of the present invention, below is a bracket in which a nipping roller 21 or 22 is vertically elevated to a fixed roller 16 or 17 used in a conventional film stretching apparatus. Since the structure is the same, the configuration and operation of elevating to one side roller (16 and 21) will be described to be applied to the other roller (17 and 22) together.
여기서, 가이드레일(31)은 서로 대칭되게 형성되며, 이 가이드레일(31)에는 베어링지지부(30)에 설치된 직선운동가이드 베어링(36)이 요철결합방식으로 접속되며, 정확하게는 삼각형을 구성하는 가이드레일의 양 경사면을 베어링(36)이 슬라이딩되게 접속되어서 세트를 구성하여 정밀한 승강동작이 이루어지게 된 것이다.Here, the guide rail 31 is formed to be symmetrical with each other, the linear guide rail bearing 36 installed in the bearing support portion 30 is connected to the guide rail 31 in the concave-convex coupling method, the guide constituting a triangle accurately The bearings 36 are slidably connected to both inclined surfaces of the rail to form a set, thereby precisely lifting and lowering.
다음으로 본 고안의 작동과정을 설명한다.Next, the operation process of the present invention will be described.
제1도와 같이 필름연신장치의 구동은 니핑로울러(21)가 고정로울러(16)상에 하강되어서 그 사이에 끼인 필름(10)을 잡아주게 되는 것이며, 이렇게 니핑로울러(21)가 승강되는 구동원은 실린더의 작동에 의한 실린더로드(40)에 의해 이루어진다.As shown in FIG. 1, the driving of the film stretching apparatus is to hold the film 10 sandwiched between the nipping rollers 21 and the fixed rollers 16. Thus, the driving source to which the nipping rollers 21 are lifted is It is made by the cylinder rod 40 by the operation of the cylinder.
이렇게 실린더로드(40)가 슬라이드브라켓(32)을 승강시키더라도 진동이나 마찰이 있게 되므로, 상기한 대로 베어링(36)이 가이드레일(31)을 따라 승강되어지므로 공차없이 정확한 승강동작이 이루어지게 된다.Thus, even if the cylinder rod 40 raises or lowers the slide bracket 32, there is vibration or friction, so that the bearing 36 is elevated along the guide rail 31 as described above, so that the accurate lifting operation is performed without tolerance. .
다시말하면, 삼각형상의 가이드레일(31) 양 경사면(30,30')을 따라 이동되도록 제5도와 같은 베어링도 역시 경사지게 형성된 것이며, 이는 니핑로울러(21)가 고정로울러(16)에 정확하게 틈새없이 접촉되므로 고르게 필름연신을 시킬 수 있게 해준다.In other words, the bearing as shown in FIG. 5 is also formed to be inclined so as to move along the inclined surfaces 30 and 30 'of the triangular guide rails 31, which means that the nipping roller 21 contacts the fixed roller 16 accurately and without gaps. This makes it possible to stretch the film evenly.
특히, 가이드레일(31)은 양 수직대(24)(26)의 후부가 각각 연장 형성된 것이어서 베어링(36)과 베어링 설치부(38) 및 후부브라켓(40)이 분해조립이 가능하며 필요에 따라 제5도와 같이 별도의 가이드레일(31)을 마련하여 부착해도 좋다.In particular, the guide rails 31 are formed by extending the rear portions of both vertical poles 24 and 26, respectively, so that the bearing 36, the bearing mounting portion 38, and the rear bracket 40 can be disassembled and assembled as necessary. As shown in Fig. 5, a separate guide rail 31 may be provided and attached.
상기한 바와 같이 본 고안을 사용함에 따라 니핑로울러가 실린더의 작용하중에 따라 변형되는 것을 방지하여 로울러 전폭에 걸쳐 균일한 니핑이 가능하게 해주고 이는 필름을 안정적으로 연신할 수 있게 해주므로 공정이 안정되고 제품의 품질향상에 크게 기여하는 효과를 얻을 수 있다.As described above, by using the present invention, the nipping roller is prevented from being deformed according to the working load of the cylinder, thereby enabling uniform nipping over the entire width of the roller, which makes it possible to stably stretch the film, thereby making the process stable. A significant contribution to improving the quality of the product can be obtained.
