Wrap N’ RollAutomatic Silverware Roller Team There is No Spoon • Patrick Goldrick • Joel McKoy • George Niou • Ryan Patterson • Lori Reinert
Agenda • Review of Problem Statement • Proposed Solution • Subsystems • Engineering Analysis • Prototype Review and Demonstration • Conclusion
Problem Statement • Problem statement: Restaurants spend a great deal of time and money to have workers complete the tedious process of manually rolling silverware into a napkin • No product available to automate process • Proposed solution: Develop a device that automatically groups one napkin, fork, and knife without use of an employee.
Proposed Solution: “Wrap N’ Roll” Utensil Container Subsystem Napkin Box Subsystem Roller & Track Subsystem Napkin Grabber Subsystem Folding Arm Subsystem
Napkin Platform Subsystem • Key features • Elevated corner supported by spring • Friction on back surface • Integrated turn-around switch
Roller & Track Subsystem • Key features • 5’ steel track • Sushi roller • Controlled by brushless DC motor • Stainless steel rods to support sushi roller when extended
Napkin Grabber Subsystem • Key features • Pivoting arms • Rubber grippers • Spring-activated locking mechanism • Mounted to sushi roller platform • No additional track or activation device needed
Napkin Grabber (cont’d) • Napkin grabber reset by acrylic piece at opposite end
Utensil Container Subsystem • Key features • Hinged in front to add utensils • Can tilt forward when loading • Ejection mechanism: • Prototype • Contoured to fit shape of silverware • Knives must have relatively flat handle
Napkin Folder Subsystem • Key features • Metal bars pivot on an angle • Triggered by trolley
Engineering Analysis • T = 1.68 N-m = 14.9 lb-in • T = F (66.2 N) * r (0.0254 m) • w = 15 rad/s = 143.3 RPM • w = v (0.38 m/s) / r (.0254 m) • P = 25.2 W • P = T (1.68 N-m) * w (15 rad/s) • Selected motor: Brushless DC Motor
Prototype • Video • Live demonstration
Conclusions • Design capable of rolling one fork and one knife into a napkin • Main subsystems include • Napkin platform • Trolley and track • Napkin grabber • Utensil containers • Napkin folders • Main difference between prototype and design was type of material
