PURPOSE:To automatize the process of work by providing a reversing device which holds and reverses a frame type filter and a mechanism which seizes and pulls out the head of the nail of a frame during the process of pulling out the nails in a wooden frame when, a frame type filter in nuclear power facilities is disposed. CONSTITUTION:A frame filter 1 is sent to the carrying-in position of a nail pulling out device 4 by a carrying-in conveyor 8. The doors 11a, 11b of a hood 11 is opened, and then the cylinder device of a carrying-in and-out device 10 is actuated to carry the frame type filter 1 to the nail-pulling out position. The frame type filter 1 is fixed by vertically forcing it by a spring type clamper 5l. After the doors 10a, 11b of the hood 11 is closed, and the nail pulling out device 4 is moved to a prescribed position while controlling a handle 46, the nail pulling out device 4 is lowered to pull out a nail. When the nail-pulling out is completed, the clamp is released, and the frame type filter is reversed by driving the reversing device 5, allowing the similar nail-pulling out operation to be repeated. |
