Downstacker

•

The Downstacker consists of four servo-driven downstacker flights: Adjustable Lower Downstacker (SM03), Adjustable Upper Downstacker (SM04), Fixed Lower Downstacker (SM05) and Fixed Upper Downstacker (SM06). Two of the flights are on one side of the downstacker, while the other two flights are on the opposite side, directly across from each other

•	After the spatula delivers a complete layer, the downstacker flights are triggered to move down one product height so that another layer can be received

•	When a full stack is complete, the downstacker flights move down to the bottom of the stack chamber and another set of flights moves in to accumulate the next stack

•	Only during a startup process, the current stack height and top layer count are determined by the 1st Carton At Downstacker (PE36102), 2nd Carton At Downstacker (PE36103) and Stack Layer Height Presented (PE36105) photo eyes
