<p>PROBLEM TO BE SOLVED: To provide a pick-up device for a work capable of eliminating residual magnetic force immediately after power-off of a magnet to avoid the deposition of dust such as iron powder and prevent the degradation of the function of a pickup unit. SOLUTION: The pick-up unit Up comprises plural types and plural pieces of large and small suction pads 1-2, plural pieces of magnet attractors 3 with adjuster plates and other plural pieces of magnet attractors, and a base B forming a header on which these are arranged and mounted in a preset number, During opening operation in attracting and opening processes for the work, the function of isolating and spacing the adjuster plates 4 of the magnet attractors 3 with the adjuster plates at a predetermined distance (stroke St) from a magnetic force plane is used for systematically eliminating or reducing the residual magnetic force to prevent the deposition of dust, etc., on the device.</p> |
