Air Bearing System & Layout Review P 13458 RIT Senior Design Team March 22, 2013 9 AM-11 AM Dresser- Rand, Painted Post http: //edge. rit. edu/edge/P 13458/public/Home
Agenda Desired Outcome of Review Systems Design using Air Bearings Fixed System Free System Air Skid Research DECISION for design direction Layout Review of Weighting Results DECISION for design direction
Desired Outcome Decisions for the air bearing system Pursue chosen design as the main mechanical design component for the remainder of MSD II Layout decision Finalize high-level design and dive into detailed design based on design aspects chosen to be pursued
Time Line STO P
Customer Needs Review From beginning of project (December 2012): Relaxed
Free Slave Frame System Pros Cons Does not require Requires level movement permanent station fixtures Stays with compressor through entire assembly Set at working height of 18” Can be bolted to floor for testing pathway More complex frame design Requires bolting into floor or substrate Must be removed for shipping 2 Frame Models necessary (MOS/HOS and HOSS) Compressor frames must be pre-painted Ergonomic issues regarding beam width
Step 1: Compressor frame is loaded onto free slave frame system
Step 2: Air pallet is slid into the fixture using integrated free rolling casters
Step 3: Air pallet inflates and allows movement to next station
Step 4: Assembly moves to next station
Fixed Slave Frame System Pros Cons Eliminates the need to Requires fixed extrusions level a pathway down the length of the line Reduces the slave frame(s) down to single horizontal beam(s) Posts will be embedded level and flat in the floor to eliminate need for leveling Fewer air lines under unit Beams can be anchored to test bed for test- do not need to remove from frame in the floor Can now only set the compressor down at designated stations
Step 1: Horizontal beams are placed on the loading station
Step 2: Compressor frame loaded is onto and fixed to horizontal beams
Step 3: Air pallet is slid into the fixture using integrated free rolling casters
Step 4: Inflation of the air pallet lifts the horizontal beams and compressor frame free of the fixture, allowing movement to the next station.
Air Platform Sizing
Air Platform Sizing The Movable Air Platform will be a minimum of 34” wide Actual available dimensions are pending, possibly larger Length of Air Platform is dependent upon unit to be moved
Layout Design 4 layout designs The team created 2 straight line and 2 U-shaped process layout designs. Several detailed factors and rankings were given to help enhance design selections. Feedback Factors and ranking weights Operator feedback People flow Parts flow Inventory Capacity: 2 days vs. 7 days Floor modeling of layout Ability to narrow down areas of major concern and improvements Straight Line vs. U-shaped process design Compare/contrast between layout designs
