본 고안은 대형 공작기계의 A. P. C장치에서 기계본체와 외부에 대기중인 파렛트(Pallet) 교환시 개폐되는 자동문의 개폐 스트록크에 비해 작은 스트록크로 개폐되도록 하여 원가절감과 용이하게 제작하게 되는 공작기계의 자동문 개폐장치를 제공하기 위한 것이다.The present invention is designed to reduce cost and facilitate production by opening and closing with a small stroke compared to the opening and closing stroke of an automatic door that is opened and closed during the exchange of pallets waiting on the outside of the machine body in the AP C device of a large machine tool. It is to provide an automatic door opening and closing device.
종래에는 자동문이 개폐되는 스트록크 정도까지 작동되는 피스톤 로드를 구비한 유압 실린더로 자동문을 개폐 하도록 하였기 때문에 우성 대형의 실린더를 사용하여야 하므로 원가상승의 요인이 되었으며, 작동시간이 길어 결과적으로 공작물 가공시간이 오래 걸리고, 자동문의 우측 슬라이드 팩(Slide Pack)과 좌측의 캠팔로우의 작동위치가 한정되어 있어 수평과 수직을 정확히 맞추어 조립하여야 하므로 조립시간이 많이 소요되며, 실린더의 피스톤로드와 자동문을 직접 연결하여야 하므로 자동문의 위치조정이 어련운 결점이 있는 것이었다.Conventionally, since the automatic door is opened and closed by a hydraulic cylinder having a piston rod operating up to a stroke that opens and closes the automatic door, the dominant large cylinder has to be used, which is a factor of cost increase, resulting in a long working time. This takes a long time, and the operation of the right slide pack of the automatic door and the cam follower on the left is limited, so it is necessary to assemble it exactly horizontally and vertically, which requires a lot of assembly time, and directly connects the piston rod of the cylinder to the automatic door. Since the automatic door positioning was difficult, it had to be flawed.
본 고안은 이상과 같은 종래의 결점을 시정하여 자동문의 개폐스트록크보다 작게 스트록크 되는 실린더로 개폐 되도록 하므로써 원가절감과 용이하게 제작되며, 개폐시간을 단축시켜 공작물 가공시간도 단축하게 되는 효과를 얻도록 한것으로서, 이하 도면에 따라 상세히 설명하면 다음과 같다.The present invention corrects the above-mentioned drawbacks as described above so that the cylinder can be opened and closed with a smaller stroke than the opening and closing stroke of the automatic door, thereby reducing the cost and making it easier, and shortening the opening and closing time, thereby reducing the processing time of the workpiece. As will be described in detail below with reference to the drawings.
좌우의 볼 베어링 또는 로울러 베어링으로 안내되어 상하로 개폐되는 도어(1)의 일측 상단에 도그(2)를 부착하고, 도어(1) 장치벽 중간에 리미트 스위치(3)(3')를 부설하여 도어(1)가 상하 개폐될시 도그(2)가 리미트스위치(3)(3')를 작동시켜 리미트 스위치(3)(3')가 신호기에 전원을 연결하여 도어(1)의 개폐 작동완료를 확인하게된 종래의 것에 있어서, 도어(1)를 지지 안내하는 볼베어링 또는 로울러 베어링이 장치된 장치실 중간에 홀더(4)를 설치하여 이 홀더(4)에 동축상으로 직경이 작은 스프로켓(5)과 스프로켓(5)의 직경보다 약 2배 이상되는 스프로켓이나 평기어(6)를 삽착하며, 홀더(4) 상방측에 유압 또는 공압으로 작동되는 실린더(7)를 수직으로 장설하고 실린더(7)옆에 스프링(8)을 걸어 실린더(7)의 로드(7')와 스프링(8)의 끝단에 체인(9)을 연결하여 이 체인(9)을 홀더(4)의 스프로켓(5)에 걸어 실린더(7)의 로드(7')에 작동에 따라 스프로켓(5)과 평기어(6)가 시계방향과 시계 역방향으로 회전하도록 하였으며, 도어(1)의 일측 주연에 도어(1)의 길이 정도되는 랙(10)을 부착시켜 랙(10)과 평기어(6) 교합되도록 도어(1)를 장설하여서된 것이다.The dog 2 is attached to the upper end of one side of the door 1 which is guided by the left and right ball bearings or the roller bearing to be opened and closed up and down, and the limit switch 3 and 3 'is installed in the middle of the door wall of the device 1 When the door 1 is opened and closed, the dog 2 operates the limit switches 3 and 3 'so that the limit switches 3 and 3' connect the power to the signal to complete the opening and closing operation of the door 1. In the related art, a holder 4 is installed in the middle of a device chamber equipped with a ball bearing or roller bearing for supporting the door 1, and the holder 4 has a coaxially small diameter sprocket 5 ) And a sprocket or spur gear 6 which is about twice as large as the diameter of the sprocket 5, and vertically installs a cylinder 7 which is operated hydraulically or pneumatically above the holder 4, and the cylinder 7 Hook the spring (8) to the side to connect the chain (9) to the rod (7 ') of the cylinder (7) and the end of the spring (8) (9) was attached to the sprocket (5) of the holder (4) so that the sprocket (5) and the spur gear (6) rotate clockwise and counterclockwise in accordance with the operation of the rod (7 ') of the cylinder (7), The door 1 is installed to attach the rack 10 about the length of the door 1 to one side of the door 1 so that the rack 10 and the spur gear 6 engage with each other.
이와같이된 본 고안은 도어(1)가 열려있는 상태의 제 2 도에 나타난 바와같이 실린더(7)에 피스톤 전진 유압을 공급하게 되면 화살표 방향으로 로드(7')가 길게 뻗어나오며, 이때 스프링(8)이 체인(9)을 당기며, 도어(1)의 중량에 의해 스프로켓(5)과 평기어(6)가 시계방향으로 회전되어 도어(1)가 밑으로 내려와 닫히게 되는 것이며, 이때, 도그(2)가 리미트스위치(3')를 조작하여 리키트스위치(3')는 신호용 센스 또는 신호기에 전원을 연결시켜 도어(1)가 닫혔음을 알리게 된것이고, 이와는 반대로 도어(1)를 제 2 도의 상태로 열때에는 실린더(7)에 피스톤 후진 유압을 공급시키면 로드(7') 실린더(7) 내부로 상승되면서 체인(9)을 당기게 되고 당겨지는 체인(9)에 의하여 스프로켓(5)이 시계 역방향으로 회전하게 되며, 따라서 회전되는 평기어(6)에 의하여 랙크(10)가 상승되어 도어(1)가 열리게 되며, 당겨지는 체인에 의하여 스프링(8)이 늘어나게 되고, 도어(1)에 따라 상승된 도그(2)에 의하여 리미트스위치(3)가 신호기에 전원을 연결 도어(1)가 닫혔음을 알리게 되는 것이다.In the present invention, as shown in FIG. 2 of the state in which the door 1 is opened, when the piston forward hydraulic pressure is supplied to the cylinder 7, the rod 7 'extends in the direction of the arrow, and the spring 8 ) Pulls the chain (9), the sprocket (5) and the spur gear (6) is rotated clockwise by the weight of the door (1) and the door (1) is lowered to close, the dog ( 2) the limit switch 3 'is operated so that the limit switch 3' is connected to a signal sense or signal for power to indicate that the door 1 is closed. When opening in the state of FIG. 1, when the piston reverse hydraulic pressure is supplied to the cylinder 7, the sprocket 5 is watched by the chain 9 being pulled up by the chain 9 as it is lifted into the rod 7 'cylinder 7. It rotates in the reverse direction, so that the rack 10 is raised by the spur gear 6 rotated. The door 1 is opened, the spring 8 is extended by the chain being pulled, and the limit switch 3 connects power to the signal by the dog 2 which is raised along the door 1 1) is closed.
이상과 같이 본 고안은 동축상으로 연결된 스프로켓(5)과 평기어(6)의 회전방향과 회전수는 동일하나 평기어(6)가 스프로켓(5)의 직경보다 2배 이상 큰것이어서 각기의 둘레 길이도 비례하므로 평기어(6)에 교합되어 이동되는 랙크(10)의 이동거리가 스프로켓(5)의 1회전 둘레의 길이보다 배이상되어 따라서 스프로켓(5)을 회전시키는 체인(9)의 이동거리가 랙크(10)의 이동거리에 1/2이상 짧으므로 체인(9)을 이동시키는 실린더(7) 로드(7')의 습동거리가 종래 도어에 직접 연결하여 개폐하게 된것보다 1/2이상 짧게되어 이와 비례되는 크기의 실린더(7)를 사용하게 된것이므로, 우선 실린더(7)의 가격이 종래것보다 저렴하여 저렴한 가격으로 제작하게 되며, 로드(7')의 스트록크가 종래것 보다 짧아 종래 도어 개폐 시간보다는 단시간에 도어(1)가 개폐되어 가공품 가공시간도 단축시키는 작용효과를 나타내는 것이다.As described above, the present invention has the same rotational direction and the number of rotations of the sprocket 5 and the spur gear 6 which are connected coaxially, but the spur gear 6 is twice larger than the diameter of the sprocket 5, so Since the length is also proportional, the movement distance of the rack 10 that is interlocked with the spur gear 6 is more than twice the length of one circumference of the sprocket 5, thus moving the chain 9 for rotating the sprocket 5. Since the distance is shorter than 1/2 of the movement distance of the rack 10, the sliding distance of the rod 7 'of the cylinder 7 which moves the chain 9 is 1/2 or more than that of the conventional door which is directly opened and closed. Since the cylinder (7) having a size proportional to this is used, the cylinder (7) is cheaper than the conventional one and manufactured at a low price, and the stroke of the rod (7 ') is shorter than the conventional one. Processed products by opening and closing the door 1 in a shorter time than the conventional door opening and closing time It indicates the operational effect of shortening disclosure liver.
