Flat and Lug Stacker

Dave Kielstra, Andrew Kroese, Greg MacLeod, and Jonathan Vander Vliet

Students were asked to design an automated flat and lug stacker for a Washington based fruit processing company. The purpose of the design was to eliminate the tedious and repetitive manual labor associated with the stacking of empty flats and lugs (i.e. large plastic trays) used to store and transport harvested fruit. The objective was to help the company reduce processing costs, while improving processing time and maintaining system reliability.
