On Edge Stacking and Sweeping Mechanism

This stacking method, when used with a mail sorting and handling machine of the type described in U. S. Patent 3,573,748, provides a system for stacking the sorted documents without a change in document orientation.

The edge stacker consists of pairs of spaced stacking rollers 1 and 2. Roller 1 is driven whereas roller 2 serves as an idler roll. An oscillating stacker gate 3 and sliding back gate 4 cooperate with sliding bottom rack 5 to support the documents. A container for the stacked documents, shown generally at 6, is supported on a suitable conveying means 7.

The computer controlled sorting mechanism, shown generally at 8, selectively releases a document 9 into the bite of the continuously running stacking rollers. The rollers move the document downward until its edge strikes the bottom stacker rack 5. At the same time, the oscillating stacker gate 3 moves the document backward against the back gate 4 pushing it out of the way of the next document. When the stacker is filled or at any selected time, it is unloaded by sliding the bottom rack 5 to the right allowing the stack to drop into the containers 6. The containers are moved out of the machine by the conveyor 7.
