<p>PROBLEM TO BE SOLVED: To prevent slippage of a sheaf of sheets in case of transferring one end part of a sheaf of sheets on a bin by a prior gripper, and transferring the same by a conveying gripper. SOLUTION: After one end part of a sheaf of sheets on a bin is transferred by a prior gripper 10, the leading end part of the sheaf of sheets is gripped by a conveying gripper 12 to be transferred. The grip force of the prior gripper 10 is made larger than the grip force of a second grip means, whereby it is possible to prevent slippage of a sheaf due to the rotating force of the sheet sheaf transferred by the prior gripper 10.</p> |
