BACKGROUND
o Portland Company founded in 1946
o Fabricator and Installer of a variety of
sheet metal products
o
o
o
o
o
Commercial HVAC
Architectural sheet metal
Industrial Air Systems
Cleanroom and Technology services
Duct Accessories
o Commissioned PSU Capstone group for a
project to improve a shop floor process
PROBLEM
o Operator moves and manually unloads sheets from cart onto the plasma table
o Intensive manual labor process – cart loaded in excess of 3000 lbs
o Steel caster wheels require large effort to push cart when loaded
De-coiling conveyor
Manual Transfer
Plasma Table
CURRENT PROCESS
o Current process time is = 2:45. Cycle Time = 0:30.
o Current carts have no onboard brakes or handles.
o The entire process is hands on.
OPPORTUNITY
o Design a machine to transfer sheet metal from the conveyor on de-coiler
to CNC plasma table.
o
o
o
o
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
o Primary motivation is to make this a “hands-free” process for safety
enhancement.
• SHEET METAL TRANSFER APPARATUS
NEW PROCESS
● Process time = 2:44. Cycle time = 0:22.
● New easier to operate
● Hands off unloading process
SHEET METAL TRANSFER APPARATUS – DESIGN
o Metal secured via Vacuum Lifter

Valves at each pad
SHEET METAL TRANSFER APPARATUS – DESIGN
o Telescoping boom motion accomplished via 3
custom trolleys and stepper motor – belt system
o Use of 2 2-phase hybrid step motors
o
Applied motion HT24-108
o Bipolar Holding Torque: 354 oz-in
o 20 total 600 lb static capacity, steel flanged rollers
utilized for motion along beam
SHEET METAL TRANSFER APPARATUS – DESIGN
o Column motion accomplished via
carriage – ball screw assembly
o 1000 lb design load
o 3 second design travel speed
o 640 in/min average velocity
SHEET METAL TRANSFER APPARATUS – DESIGN
o Use of industrial PLC to control Boom, stepper
motors
o Wiring diagrams and block diagrams developed
o Emergency shutoff and
limit switches
incorporated for
additional safety
measures
