PURPOSE:To make a work possible to be efficiently taken piece by piece out of a stacked body having a protruding part at its end part, by installing a work attracting magnet in a tip end of a liftable slide arm in a lifting device. CONSTITUTION:A lifting cylinder 49 is made to go down in a state that a slide arm 4 is directed to a stacking block 2, and a topmost work W (for example, a frame body to be used for a yield strength panel) of a work stacked body on the stacking block 2 is attracted with magnetic attraction by a energized magnet 5 at a tip of the arm 4. Next, the lifting cylinder 49 is contracted shorter, and the work W is uplifted beyond a protruding part B1 at the end part. Afterward, a selector valve is selected to where it should be, and a cylinder 55 is extended longer as adjusting its speed, then the work W lifted with the pushing piece 56 is pushed forward toward a receiving block 3. At this time, the slide arm 4 moves while extending a damper cylinder 12 because the magnet 5 attracts the work with magnetic attraction. |
