3. Previously...

4. Revised Design

5. Linear Motion and Hopper
1 stationary head, 3 moveable heads
Move along single ACME screw
Supported by upper and lower rail
Desire is to place a hopper on each actuator
Hopper sizing and availability needs further research

6. Frame and Impact Surface
I-beam for the center column
Square tubing for frame structure
FEA analysis showed extended support had greater strength
Raised impact surface

7. Actuators Performed Tensile test and Impact test in ME 411
Used to determine impact required to fasten Gripnail
Magnet holds Gripnail
Secondary actuator loads Gripnail

8. Control Panel 8 electronic air solenoids 4 for impact actuator
4 for loading actuator
PLC unit for machine control
