Material separation device and material separation process

摘要

Material separation device (1) comprises a support component (2), a blower (3), a suction component (4), a suction pad drive device (5) and a control device (10). The blower (3) blows air on a plurality of aluminum plates (11) placed on the support component (2) to float the uppermost aluminum plate (11). The suction component (4) uses suction pads (411) to clamp and hold the uppermost aluminum plate (11) from above while the air is being blown. The suction pad driving device (5) drives the suction component (4) up and down by using servomotors (50) as a driving source. The control device (10) performs a control such that the suction pads (411) clamping the aluminum plate (11) are lifted by the suction pad driving device (5) to a temporary holding position (h1) and the suction pads (411) for a specific one Duration at the temporary stop position (h1) are stopped while the air is stopped, and the suction pads (411) are then lifted by the suction pad drive devices (5) to a conveying position (h2).
