The separator suction device is capable of suctioning and conveying a separator stored in a state where a plurality of the separators are stacked. The separator suction device includes a first arm that includes a first suction portion capable of suctioning the separator by a negative pressure, a second arm that includes a second suction portion capable of suctioning the separator by a negative pressure, and a turning mechanism that moves the first arm and the second arm to selectively arrange the first arm and the second arm at any one of a follow-up position to follow a warped shape of the separator or a correction position to correct the warpage of the separator. ## Claims ### Claim 1 A separator suction device capable of suctioning and conveying a separator stored in a state where a plurality of the separators are stacked, the separator suction device comprising: a first arm that includes a first suction portion capable of suctioning the separator by a negative pressure; a second arm disposed to form a pair with the first arm, rotating around a shared rotational axis, the second arm including a second suction portion capable of suctioning the separator by a negative pressure; and a transporting unit that moves the first arm and the second arm to selectively arrange the first arm and the second arm at any one of a follow-up position to follow a warped shape of the separator or a correction position to correct the warpage of the separator wherein the transporting unit includes a drive unit that moves the first arm and the second arm; wherein the drive unit includes a rotary actuator that rotates the first arm and the second arm around the shared rotational axis. ### Claim 2 (depends on 1) The separator suction device according to claim 1, wherein the transporting unit has a configuration in which the first arm and the second arm are moved from the follow-up position to the correction position when the negative pressures of the first suction portion and the second suction portion become equal to or more than a preliminarily set threshold value. ### Claim 3 (depends on 1) The separator suction device according to claim 1, wherein the transporting unit further includes a control unit that controls the drive unit. ### Claim 4 (depends on 1) The separator suction device according to claim 1, wherein the first suction portion and the second suction portion suction inner portions inwardly separated from an outer periphery of the separator by a predetermined distance.
