  1. Experimental Silo Packer Team 7 - Project 99.07 Team Members: J. M. Tate, J. Acheson, P. Sullivan, and A. Abumohor Advisor: Dr. J. Glancey Sponsor: Dr. Limin Kung

  2. Introduction: Silo Basics

  3. Problem

  4. Experimental Silo Packer Mission: The purpose of our team is to design and build a means to quickly and reproducibly load a test silo without requiring extensive manpower. Approach: We will use the Total Quality Design Process, through the SpreadSheet Design Process on Microsoft Excel.

  5. Academic Dr. Limin Kung Dr. Martin Stokes Dr. Joseph Harrison Industrial Mr. Chris Rhoden Ms. Carol Myers Customers • Agricultural • Mr. Richard Morris

  6. Updated Wants: 1-5 1) Reproduce Desired Results 2) Not Physically Demanding 3) Fast Operation 4) Simple Operation for User 5) Low Cost

  7. Updated Wants: 6-10 6) Easy to Clean 7) Easy to Repair 8) Easily Transportable 9) Variable Silo Size 10) Easy to Store

  8. System Benchmarks • Stokes Pneumatic Loader • Stokes Front End Loader • Trash Compactors • Shotshell Loaders • Pharmaceutical Capsule Filling Machines • Soda Can Crushers Main Competitor: Stokes Pneumatic Loader

  9. Metrics: 1 to 5

  10. Metrics: 6 to 10

  11. Functional Benchmarking Functions: • Compacting Devices • Material Transport • Container Transport • Pressure and Load Sensors • User-Interface Controllers

  12. Compacting Devices • High-Velocity Blowing Compactor • Distributed Weight Packer • Rolling Compactor • Hydraulic Power Press • Extrusion Screw Best Practice: Pneumatic Piston

  13. Material Transport • Bagging Lawnmower • Vacuum Cleaner • Two-Stage Silage Blower • Multiple Ram Silage Mover • Screw Feeder Best Practice: Screw Feeder

  14. Container Transport • Case Conveyor • Cola Bottling Line • Cigarette Packing Apparatus Best Practice: Conveyor Belt

  15. Pressure and Load Sensors • Pressure Transducer • Load Cell • Piezoelectric Pressure Sensors Best Practice: Piezoelectric Pressure Sensors

  16. User-Interface Controllers • Computer Keyboard • Foot Pedal • Video Game Controller • Push Button Best Practice: Foot Pedal

  17. Concepts Pros and Cons based upon metrics and target values

  18. Concept 1 Feeding Mechanism: ScrewForce Control: MechanicalSink Depth: Feed Stopping Switch

  19. Concept 1 We start by installing one stopper into the minisilo. 8.25in

  20. Concept 1 This minisilo is then locked into the sliding carriage. minisilo Sliding carriage

  21. silage Downward Force finger Cut off switch Concept 1 Metrics Pressure per layer Change in pressure per layer Price

  22. Concept 1 The cut off switch satisfies the proper sink distance constraint. Sink distance

  23. Concept 2 Force: Pneumatic PistonForce Control: ValveFeeding Mechanism: Linear Reciprocating Feeder

  24. 8.25in Concept 2 Again, we start by installing one stopper into the minisilo. Stopper

  25. Concept 2 Minisilo Clamp

  26. Concept 2 Add silage Metric User actions

  27. Concept 2 The reciprocating feeder pushes the silage into the packing chamber.

  28. Concept 2 Packer is driven by the pneumatic piston Metrics Pressure per layer Change in pressure per layer Price

  29. Concept 2 Red marks

  30. Concept 2 2nd stopper is installed at the proper sink distance.

  31. Schedule • New approach • Actual to date • Detailed to next presentation • Generic remainder of time • Estimated budget
