  • Material separation device and material separation method
    Patent number: 10471495
    Abstract: A material separation device comprises a placement component, a blower, a suction component, a suction pad driver, and a controller. The blower blows air at a plurality of aluminum sheets that have been stacked on the placement component to float an uppermost aluminum sheet. The suction component uses suction pads to chuck and hold the uppermost aluminum sheet from above while the air is being blown. The suction pad driver drives the suction component up and down, using servomotors as a drive source. The controller performs control so that the suction pads chucking the aluminum sheet are raised to a temporary stopping position by the suction pad driver, and the suction pads are stopped for a predetermined length of time at the temporary stopping position while the air is stopped, and the suction pads are then raised by the suction pad drivers to a conveyance position.
