3. 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

4. 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

5. 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.

6. 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.

8. New Process Process time = 2:44. Cycle time = 0:22.
New easier to operate
Hands off unloading process
