본 발명은 중량체인 철판 코일 등을 간편하게 이송할 수 있도록 하는 3단대차장치에 관한 것으로, 더 자세하게는 전후이송레일을 따라 전후방향으로 이동되는 트래버스카(Traverse car)에 좌우이송레일을 따라 좌우방향으로 이동되는 피더카(Feeder car)가 탑재되고, 피더카에 다시 전후이송레일을 따라 전후방향으로 이동되는 돌리카(Dolly car)가 탑재된 것에 관한 것이다.The present invention relates to a three-stage trolley for easily transporting a heavy chain iron plate coil, etc. More specifically, the traverse car is moved in the front and rear directions along the front and rear transport rails (left and right along the left and right transport rails) The feeder car which is moved to the vehicle (Feeder car) is mounted, and the feeder car is mounted on the dolly car (Dolly car) is moved in the front and rear direction again along the front and rear transfer rail.

일반적으로 중량체인 철판 코일 등은 생산현장에서 보관장소까지 인력으로 운반하기가 불가능하게 되므로 전후방향 및 좌우방향으로 이송되는 대차장치를 통해 이송, 적재하는 것이 보통이다.In general, heavy chain iron plate coils are not transported by manpower from the production site to the storage site, so it is common to transfer and load them through a trolley that is transported in the front-back direction and the left-right direction.

본 발명은 특히 전후이송레일을 따라 전후방향으로 이동되는 트래버스카(Traverse car)에 좌우이송레일을 따라 좌우방향으로 이동되는 피더카(Feeder car)가 탑재되고, 피더카에 다시 전후이송레일을 따라 전후방향으로 이동되는 돌리카 (Dolly car)가 탑재되어 생산장소의 코일을 간편하게 전후방향 및 좌우방향으로 이송하여 보관장소에 적재할 수 있도록 하는 3단대차장치에 관계하는 것이다.The present invention is particularly equipped with a feeder car which is moved in the left and right directions along the left and right transport rails in the traverse car which is moved in the front and rear directions along the front and rear transport rails, and the feeder car is again along the front and rear transport rails. It is related to a three-stage trolley that is equipped with a dolly car moving in the front and rear direction so that the coil of the production place can be easily transported in the front and rear and right and left directions to be loaded in the storage place.

상기 3단대차장치에 있어서 생산장소의 코일은 본체 내부에 승강실린더가 설치된 돌리카를 통해 본체의 상단에 적재받침대가 마련된 피더카에 적재되어 보관장소로 이송된 후 다시 돌리카에 의해 보관장소의 보관적재대에 하역되는 바, 생산장소에서 돌리카를 통해 코일을 피더카의 적재받침대에 적재한 후 트래버스카와 피더카를 통해 보관장소의 일 보관적재대 전방 또는 후방까지 이동하고, 돌리카의 승강실린더를 작동시켜 상승되는 승강실린더 작동로드 상단의 받침블록으로 코일을 들어올린 상태에서 돌리카를 전방 또는 후방을 이송시켜 보관적재대 상부에 코일을 위치시킨 다음 승강실린더의 작동로드 및 받침블록, 코일을 하강시키게 되면 보관적재대에 코일을 안전하게 하역할 수 있게 된다.In the three-stage trolley, the coil of the production site is loaded on a feeder car equipped with a loading support on the top of the main body through a dolly car installed with a lifting cylinder inside the main body, transferred to a storage place, and then stored again by a dolly car. At the production site, the coil is loaded into the feeder car's support base through the dolly at the production site, and then moved to the front or rear of the storage rack at the storage site through the traverse car and the feeder car, and the dolly lift cylinder is operated. When the coil is lifted up to the support block on the upper side of the lifting cylinder operation rod, the coil is moved forward or backward to position the coil on the upper part of the storage rack, and then the operation rod and the support block of the lifting cylinder are lowered. The coil can be unloaded safely in the storage rack.

그런데 종래의 3단대차장치에 있어서는 생산장소에서 피더카의 적재받침대에 코일을 적재할 수 있도록 하고 보관장소에서 보관적재대에 이송된 코일을 안착시킬 수 있도록 하는 돌리카의 승강실린더가 본체에 완전 고정 설치되었기 때문에 승강실린더의 작동로드가 승강될 때에 중량체인 코일을 받쳐주는 받침블록을 통해 작동로드 및 승강실린더에 편하중이 걸리게 되어 작동로드의 승강동작이 원활하게 이루어지지 못하게 됨은 물론 승강실린더의 고장이 유발되거나 승강실린더의 수명을 단축시키게 되는 문제가 있었다.However, in the conventional three-stage bogie device, a dolly lift cylinder that allows the coil to be loaded on the feeder's loading support at the production site and seats the coil transferred to the storage loading table at the storage location is completely installed on the main body. Since it is fixedly installed, the working rod and the lifting cylinder are biased by the supporting block that supports the heavy chain coil when the lifting rod of the lifting cylinder is lifted. There was a problem that caused a failure or shorten the life of the lifting cylinder.

또한 종래의 3단대차장치에 있어서는 돌리카를 통해 생산장소에서 피더카의 적재받침대에 일정 폭의 코일을 적재할 때에 피더카의 적재받침대의 정중앙에 코일 을 안착시킬 수 없었기 때문에 코일의 이송안정성이 떨어지게 됨은 물론 각종 안전사고와 피더카의 고장의 원인으로 작용하게 되는 문제가 있었다.In addition, in the conventional three-stage bogie, when a coil of a certain width is loaded in the feeder's loading support at the production site through the dolly, the coil cannot be seated in the center of the loading support of the feeder car. Of course, there was a problem that acts as a cause of various safety accidents and failure of the feeder car.

또한 종래의 3단대차장치에 있어서는 대차에 탑재되어 있는 콘트롤패널의 프로그램 로직 콘트롤러(PLC; Programmable Logic Controller)의 점검이나 수리, 그리고 설정변경시 등에 작업자가 대차에 탑승하여 점검하여야 했기 때문에 조업이 불가능하게 됨은 물론 각종 안전사고의 우려가 많게 되는 등의 문제가 있었다.In addition, in the conventional three-stage bogie, operation is impossible because the operator had to check the trolley on the trolley for checking or repairing the control panel of the control panel mounted on the trolley, or when changing the setting. Of course, there were problems such as a lot of safety accidents.

본 발명은 상기와 같은 종래의 실정을 감안하여 안출한 것이며, 그 목적이 피더카의 적재받침대나 보관장소의 보관적재대에 코일을 안착시키는 돌리카의 승강실린더에 편하중이 걸리는 것을 방지할 수 있도록 하는 3단대차장치를 제공하는 데에 있는 것이며, 그 다른 목적이 피더카 적재받침대의 정중앙에 코일을 안착시킬 수 있도록 하는 하는 3단대차장치를 제공하는 데에 있는 것이다.The present invention has been devised in view of the above-described conventional situation, and the object thereof can be prevented from being subjected to a comfortable load on a lifting cylinder of a dolly which seats a coil on a loading stand of a feeder car or a storage stand of a storage place. The third object is to provide a three-stage bogie, which is intended to provide a three-stage bogie, which allows the coil to be seated in the very center of the feeder loading stand.

아울러 본 발명은 그 또 다른 목적이 대차에 탑재된 제어프로그램의 점검이나 수리, 설정변경 등을 보다 용이하게 할 수 있도록 하는 3단대차장치를 제공하는 데에 있는 것이다. It is still another object of the present invention to provide a three-stage trolley which makes it easier to inspect, repair, or change a setting of a control program mounted on a trolley.

본 발명은 상기의 목적을 달성하기 위하여 돌리카의 본체에 승강실린더를 트러니온 방식(Trunnion Type)으로 지지하고 승강실린더의 작동로드와 받침블록을 구 면부싱(Spherical Bushing)과 스프링와셔를 통해 체결하는 것과, 피더카의 적재받침대의 선단 및 후단에 코일폭 검출센서를 설치하는 것과, 대차와 지상측에 광통신 유니트를 설치하여 대차 이동시나 정지시에 항상 광통신 유니트를 통해 제어프로그램의 내용을 전송하여 지상의 프로그램 로직 콘트롤러 로더(PLC Loader)에서 프로그램의 읽기/쓰기가 가능하도록 한 것 등을 특징으로 한다.The present invention supports the lifting cylinder to the main body of the dolly in the trunnion type (Trunnion Type) to achieve the above object and fastening the working rod and the support block of the lifting cylinder through the spherical bushing and the spring washer. And the installation of coil width detection sensors at the front and rear ends of the feed stand of the feeder car, and the optical communication unit installed at the bogie and the ground side to transmit the contents of the control program through the optical communication unit at all times when the vehicle is moved or stopped. It is possible to read / write the program in the program logic controller loader on the ground.
