Abstract An apparatus for preventing sheets conveyed successively on a conveyor from being stacked up at the end of the conveyor in a disordered state in alignment is improved so as to assure stable operation without deforming edge portions of the handled sheets. The improvements reside in that the apparatus comprises a pair of guide members disposed on a sheet passageway above an inlet of a sheet stack-up section respectively so as to be swingable in the direction of traveling of the sheets and adjustable in positions in the lateral directions, a drive for independently adjusting the positions of the guide members in the lateral directions, sensors for detecting opposite side edge portions of a sheet moving on a transporting conveyor, and a control responsive to results of detection by the sensors for actuating the drive to adjust the positions of the respective guide members in the lateral directions.
An apparatus for preventing disorder in sheet alignment, having a pair of guide members disposed on a sheet passageway above an inlet of a sheet stack-up section respectively so as to be swingable in the direction of traveling of the sheets and adjustable in positions in the lateral directions, drive means for independently adjusting the positions of said guide members in the lateral directions, sensor means for detecting opposite side edge positions of a sheet moving on a transporting conveyor, and control means responsive to results of detection by said sensor means for actuating said drive means to adjust the positions of said respective guide members in the lateral directions.
