Abstract:
1. A paper handling system comprising an ejection assembly, a receiving assembly, and a plurality of paper sheets to be transferred by the ejection assembly to the receiving assembly, wherein: the ejection assembly comprises a vertical slot with a depth and a length; said plurality of paper sheets is received vertically in said vertical slot and each of the paper sheets having a bottom edge inside said vertical slot; said ejection assembly comprises an ejection member that pushes said plurality of paper sheets horizontally out of the vertical slot in a direction parallel to the length of the vertical slot and into the receiving assembly; wherein the receiving assembly comprises: a horizontal, rotatable shaft with a length and a longitudinal groove; and a stacking bin located below and in front of the shaft and having a bin floor surface and a front wall; and wherein said horizontal, rotatable shaft is motor-driven to rotate on a horizontal axis between a paper-receiving position and a paper-dropping position, wherein, when the shaft is in the paper-receiving position, the groove is upward and receives the bottom edges of the plurality of paper sheets when the ejection member pushes said paper sheets out of the vertical slot, and wherein, when the shaft is motor-driven into the paper-dropping position, the groove is rotated 90-135 degrees forward toward the stacking bin to drop said plurality of paper sheets forward into said bin; and wherein the paper handling system further comprises: a lift bar provided in the stacking bin, on which lift bar the plurality of papers fall when dropped from the shaft to said bin, said lift bar raising said bottom edges of the paper sheets above the bin floor surface; and said horizontal, rotatable shaft further comprising at least one push bar extending from said shaft opposite the groove, wherein, when the shaft is motor-driven to return to the paper receiving position after dropping said plurality of papers into the bin, said at least one push bar rotates with the shaft so that a front surface of said at least one push bar hits said bottom edges of the plurality of paper sheets that are raised by said lift bar, to align said bottom edges and push said plurality of paper sheets forward against the front wall of the stacking bin.
