Benchmark's Counter Stacker accepts a single lane of product and presents two alternating lanes of shingle stacked product in counted groups for hand loading into trays or the infeed of a cartoner. A pneumatically actuated diverter divides the single lane of product into two lanes by count. A programmable controller is used to set the group count. Each lane of product is transferred onto a common conveyor at separate locations. Product is shingle stacked on the conveyor to conveyor transfer using an adjustable chute. The counted groups are presented to the operator.
