Drive Method And Drive Device For Fluid Pressure Cylinder
Abstract: A drive device (10) for driving a fluid pressure cylinder (12) has an air supply source (52) which supplies air, a switching valve (14) which switches between the supply and discharge of the air to and from the fluid pressure cylinder (12), bypass piping (20) which connects the head-side cylinder chamber (16) and rod-side cylinder chamber (18) of the fluid pressure cylinder (12), and a bypass switching valve (22) which switches between the states of flow of air through the bypass piping (20). Air in the head-side cylinder chamber (16) is supplied to the rod-side cylinder chamber (18) through the bypass piping (20) by setting the bypass switching valve (22) to an open state in a return stroke of the fluid pressure cylinder (12).
