Meet the Team Reuben S aarloos Peter Betten Lars Johnson Mitch DeBruin Introduction Opportunity Planning Design Conclusion 2

Proj ect Overview  Proj ect: Designing and prototyping a steel reinforced hose cutting machine  For whom: MFP Automation Engineering 3 Introduction Opportunity Planning Design Conclusion

MFP New Hose Assembly Process 1 2 3 4 5 Technician The cut hoses Mark hoses for Factory Reel measures hose Technician pulls are then blown- fittings – fittings size #4- #20 and marks it, hose to saw and out from both must be on a S teel Reinforced double checking cuts hose sides to clean hose a specific Hydraulic Hose his insides length measurement 10 9 8 7 6 Wrap PTS Tag Attach Caps on Install fittings Tighten fittings around portion ends of crimped Crimp Fittings by hand (only (hydraulic) of hose fittings hand tight) 4 Introduction Opportunity Planning Design Conclusion

Budgeting BOM MFP allowed us lots of wiggle room with our budget, which was mainly due to the costly price =$7,000 of some components needed MFP did not want us to extend beyond $10,000 Why the Large Gap: - Heavily underestimated expense of Conveyor S ystem =$9,360 - Conveyors - High Friction Belt material - Custom Motors Overall Cost of Conveyor S ystem = $5,267 We went over our original goal but succeeded in staying under $10,000 6 Introduction Opportunity Planning Design Conclusion

Design 7 Introduction Opportunity Planning Design Conclusion

Cutting S ystem Implemented S ystem: Bring the hose into the saw Merits: - Allow hose to bend, causing no pinching - Increase lifecycle of saw blade - Creates cleaner cut - Adaptable to various hose sizes Discarded Alternatives: - Bring the saw into the hose - Guillotine 8 Introduction Opportunity Planning Design Conclusion

Feeding S ystem Implemented S ystem: Conveyor Belts Merits: - Maximize surface area to reduce slippage - Capable of variable hose sizes - Variable feeding rates 9 Introduction Opportunity Planning Design Conclusion

Measuring S ystem Implemented S ystem: Rotary Encoder Merits: - Accurate and Precise - Less tolerance stack up - Bi-directional Discarded Alternatives: - Using conveyor run time 10 Introduction Opportunity Planning Design Conclusion

Control S ystem Implemented S ystem: PLC S ystem Merits: - Industry standard controller - HMI feature - Easily upgradable - Robust S ystem Discarded Alternatives: - RaspberryPi - Arduino 11 Introduction Opportunity Planning Design Conclusion

S pool Mount Used a pneumatic cylinder with a custom head as a j am break, to prevent unwanted rotation. Discarded Alternatives: - Rotary Dampener - Clutch Bearing 12

Proj ect S tatus  Waiting on ordered parts (VFD, S aw Motor, Conveyors, Rotary Encoder)  Rotary encoder delayed from April 30 to May 14  All components fabricated, waiting for conveyors to mount with proper alignment  Debug Code when Conveyors Arrive  Test will be done with timed signal as proof of concept without encoder. 13 Introduction Opportunity Planning Design Conclusion
