Abstract
A counter-ejector is described for stacking relatively flat sheet articles. The counter-ejector includes a main frame that is selectively movable about a pivot axis. An infeed conveyor is provided on the main frame defining a forward path of travel for sheet articles. The infeed conveyor includes a discharge end positioned adjacent a stack forming magazine where individual sheet articles from the infeed conveyor accumulate in a stack. An ejector adjacent the stack forming magazine is movable across the stack forming magazine from a stack engaging position adjacent the stack forming magazine to a shifted position at a stack compression station. A stack compressor at the stack compression station is positioned to receive a stack of sheet articles from the ejector. A compression linkage joins the stack compressor and main frame, with links arranged to adjustably open and close the stack compressor responsive to movement of the main frame about the pivot axis.
