Background Portland Company founded in 1946 Fabricator and Installer of a variety of sheet metal products Commercial HVAC Architectural sheet metal Industrial Air Systems Cleanroom and Technology services Duct Accessories Commissioned PSU Capstone group for a project to improve a shop floor process

Problem Operator moves and manually unloads sheets from cart onto the plasma table Intensive manual labor process – cart loaded in excess of 3000 lbs Steel caster wheels require large effort to push cart when loaded De-coiling conveyor Manual Transfer Plasma Table

Current Process Current process time is = 2:45. Cycle Time = 0:30. Current carts have no onboard brakes or handles. The entire process is hands on.

Opportunity Design a machine to transfer sheet metal from the conveyor on de-coiler to CNC plasma table. Accommodate Sheet metal between 26 and 16 ga flat sheets. Largest sheet to be 120 in x 72 in Smallest sheet to be 36 in x 36 in Most common (95%) sheet is between 72 and 120 in long and 60 in wide Primary motivation is to make this a “hands-free” process for safety enhancement.
