Claims (2)

In a rolling system having a non-contact cutting machine that performs a non-contact cutting operation on a sheet at the top of a stack of paper from a bundle of sheets, the non-contact cutting machine includes one or a plurality of non-contact suction chucks. The non-contact suction chuck machine is lowered from a first height to a second height, and is placed in an upper space of the sheet bundle after the non-contact suction chuck machine is lowered from a first height to a second height. The uppermost sheet is sucked up by the negative pressure effect of the airflow and sucked non-contacted, and then lifted to the third height and temporarily stopped without reducing the interval between the non-contact sucking chucks. And the other sheet of the sheet bundle is separated and the non-contact suction chuck machine rises to the fourth height or the first height in a state where the uppermost sheet of the sheet bundle is non-contact sucked. Non-contact cutting characterized by System turning with the out machine. In a rolling system having a non-contact cutting machine that performs a non-contact cutting operation on a sheet at the top of a stack of paper from a bundle of sheets, the non-contact cutting machine includes one or a plurality of non-contact suction chucks. And a mounting base for fixing the one or a plurality of non-contact suction chucks, and the non-contact cutting machine descends from the first height to the second height and then in the space above the sheet bundle . The uppermost sheet is sucked by non-contact after being sucked up by the negative pressure effect of the air flow , and then the plurality of non-contact sucking chucks and the uppermost sheet are reduced without reducing the interval between the suction surfaces. While the non-contact cutting machine completes raising at the second height or to the third height, both-end non-contact suction chucks installed at both inner ends of the plurality of non-contact suction chucks are initially set around a virtual fulcrum. Rotate from state The gap generated between the suction portion in the vicinity of the left and right side surfaces of the uppermost sheet adsorbed by this and the lower sheet bundle is increased, and then the non-contact cutting machine is at the second height or third. The non-contact suction chuck at both ends reversely rotates around the virtual fulcrum and returns to the initial state while the ascent is completed, and then the non-contact cutting machine does not contact the uppermost sheet of the bundle of sheets. Non-contact cut-out characterized by rising to the fourth height or the first height after stopping at the third height in the adsorbed state or without stopping at the third height System with a machine.
