摘要：A separation conveyance device comprises: a separation unit that includes a first roller feeding a conveyance object, and a load unit applying a load to the fed conveyance object, and separates one conveyance object from conveyance objects; a second roller that conveys the fed conveyance object; a driving unit that causes a motor to rotate the first roller at a first linear speed and the second roller at a second linear speed higher than the first linear speed; a connection unit that cuts off the motor's power from the first roller when first load torque toward a rotation direction of the first roller is equal to or larger than a certain value; a detection unit that detects second load torque in the direction opposite to a rotation direction of the motor; and a determination unit that determines a separation state of the conveyance object based on the second load torque.

主权项：1. A separation conveyance device, comprising: a separating device including, a first roller configured to feed a conveyance object, anda load unit configured to apply a load to the conveyance object fed by the first roller, and to separate the conveyance object from a plurality of conveyance objects using the load; a second roller configured to convey the conveyance object fed from the first roller; a motor configured to generate power; a transmission system configured to, rotate the first roller at a first linear speed and the second roller at a second linear speed higher than the first linear speed based on the power of the motor, andcut off the power of the motor from the first roller when the second roller conveys the conveyance object; and a controller configured to determine a separation state of the conveyance object by the separating device based on load torque applied from the transmission system to a motor shaft of the motor in a direction opposite to a rotation direction of the motor shaft.
