<P>PROBLEM TO BE SOLVED: To provide an impeller stacking device capable of reducing take-in failure when papers having a length in a predetermined range is taken in the impeller stacking device. <P>SOLUTION: A point where a lower line of a conveying belt and a circumscribed circle of the impeller intersect with each other is set to be point A and chord length is set to SL. After the front impeller reaches the point A, take-in of the papers P is started at a position where it is rotated from the point A by 3° and a point where the subsequent impeller crosses a line of the conveying belt 4 is set to be point B. (A) a rotation angle θ until the subsequent impeller reaches the point B after the front impeller reaches the point A. (B) a distance L1 from the point A to the point B. (C) a movement distance L2 of the papers P until the subsequent impeller reaches the point B. (D) a margin amount y (mm) where a rear end of the papers P is not clamped by the impellers. The above (A) and (B) are geometrically calculated, (C) is calculated from a rotation time of the impeller and a conveying time, and the margin amount y is calculated by y=L2-(length 175 mm)-L1. The chord length SL capable of securing the rotation angle θ and the margin amount y is preferably 75 mm. <P>COPYRIGHT: (C)2009,JPO&INPIT |
