Abstract

This mechanism is a feed hopper for sheet paper in which the paper resides in a near-vertical stack. The paper supply can be replenished without interruption of the feed. As in 1, the hopper includes end plate 1 sloped so as to be in a near-vertical plane. Plate 1 is located adjacent-picker belt 2. The picker mechanism also includes separator wheel 3 and restraint belt 4. Retainer plate 5 is sloped in substantially the same plane as plate 1 and is located at the opposite side of the hopper. The latter also includes backup plate 6, intermittently driven hopper belt 7, driver 8, and sensor 9. In operation, belt 2 essentially feeds a paper sheet upwardly from its bottom side and out between wheel 3 and belt 4 to the utilization unit not shown.

Paper Feed Hopper

This mechanism is a feed hopper for sheet paper in which the paper resides in a near-vertical stack. The paper supply can be replenished without interruption of the feed. As in 1, the hopper includes end plate 1 sloped so as to be in a near-vertical plane. Plate 1 is located adjacent-picker belt 2. The picker mechanism also includes separator wheel 3 and restraint belt 4. Retainer plate 5 is sloped in substantially the same plane as plate 1 and is located at the opposite side of the hopper. The latter also includes backup plate 6, intermittently driven hopper belt 7, driver 8, and sensor 9.

In operation, belt 2 essentially feeds a paper sheet upwardly from its bottom side and out between wheel 3 and belt 4 to the utilization unit not shown. As the paper is fed out, sensor 9 causes driver 8 to intermittently operate belt 7 to make certain that the stack of paper remains adjacent belt 2 as in drawing 2. As the supply of paper dwindles, additional paper can be added by removing plate 5 without requiring interruption of the feed. The combination of the frictional surface of belt 2 and the slope of the paper allows the paper to stand up when retainer 5 is removed to replenish the paper supply.
