RelaxedFrom beginning of project (December 2012):Lauren5Free Slave Frame SystemProsConsDoes not require permanent station fixturesStays with compressor through entire assemblySet at working height of 18Can be bolted to floor for testingRequires level movement pathwayMore complex frame designRequires bolting into floor or substrateMust be removed for shipping2 Frame Models necessary (MOS/HOS and HOSS)Compressor frames must be pre-paintedErgonomic issues regarding beam width

6Step 1: Compressor frame is loaded onto free slave frame system

Cole7Step 2: Air pallet is slid into the fixture using integrated free rolling casters

Cole8Step 3: Air pallet inflates and allows movement to next station

Cole9Step 4: Assembly moves to next station

Cole10Fixed Slave Frame SystemProsConsEliminates the need to level a pathway down the length of the lineReduces the slave frame(s) down to single horizontal beam(s)Posts will be embedded level and flat in the floor to eliminate need for levelingFewer air lines under unitBeams can be anchored to test bed for test- do not need to remove from frame

Requires fixed extrusions in the floorCan now only set the compressor down at designated stations

11Step 1: Horizontal beams are placed on the loading station

Shawn12Step 2: Compressor frame loaded is onto and fixed to horizontal beams

Shawn13Step 3: Air pallet is slid into the fixture using integrated free rolling casters

Shawn14Step 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

Jordon16Air Platform SizingThe Movable Air Platform will be a minimum of 34 wideActual available dimensions are pending, possibly largerLength of Air Platform is dependent upon unit to be moved Jordon17Layout Design 4 layout designsThe team created 2 straight line and 2 U-shaped process layout designs. Several detailed factors and rankings were given to help enhance design selections.
