Patent ID: 8876681

Claim:
A counter ejector that counts folded boxes to make a predetermined number of the folded boxes into a batch and feeds the batch to a post process, the counter ejector comprising: a hopper that receives the boxes and accumulates the boxes therein; a lower conveyer that is disposed below the hopper, and moves a belt horizontally to send the batch to the post process; a ledge that moves toward an inner side of the hopper to receive the boxes in the hopper when the boxes accumulated in the hopper reach the predetermined number; an elevator that is disposed below the hopper so as to move up and down, so that the elevator receives the boxes accumulated in the hopper when lifted, and places the batch of the boxes on the lower conveyer when lowered; a press bar that is disposed below the ledge so as to be moveable vertically with respect to the ledge, and presses the batch on the elevator by moving vertically downward relative to the ledge; a relative movement servo motor that moves the press bar vertically relative to the ledge; and a controlling unit that controls the relative movement servo motor, wherein the controlling unit includes an output torque controlling unit that controls an output torque of the relative movement servo motor such that the press bar presses the batch with a predetermined force.
