ABSTRACT:
A heavy article inversion device is provided, in which the inverting operations may be performed in a short time by reducing the size of the heavy article inversion device comprising a pair of inversion boards that may be revolved about a common rotary shaft supported in the center of a base between the horizontal state and the angles of revolution of less than 180 degrees from the horizontal state, and a pair of cam plates each fixed to the corresponding one of the pair of inversion boards and having its proximal end side rotatably fixed to the common rotary shaft, in which each one of the pair of cam plates has a curved lower outer circumferential surface extending from the proximal end side toward the radial outside end and which may be engaged by the rod of each respective one of the pair of linear drive mechanisms when the rod is being moved out of and moved back into the corresponding cylinder of the respective liner drive mechanism, thereby causing the respective cam plate to be rotated about the common rotary shaft. In accordance with the present invention, the direction in which the rod of each one of pair of the linear drive mechanisms may be moved out of or moved back into the cylinder occurs from the obliquely downward direction toward the direction of the common rotary shaft.
