156B Week 4

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Submitted initial CNC pillow block bearing to Mike

    •  got a response back about redesign that minimizes curves and more utilization of punching holes and tapping threads.

    • Redesign and submission on Monday

  • Redesign for second layer of base plate holder

  • Finished research for heating of glycerin--> moving forward with heating tapes.

  • Finished research for increasing filling speed --> moving forward with Arduino

  • Finished research for automatic gauge detection --> moving forward with diffuse sensor

Accomplishments from Previous Week

• • Purchased half of roller track design with slight delays: ETA 10 days

    • Logistics between Ian and JT sorted out

  • Purchased conveyor belt: ETA 10 days

  • Elaine and Desi went to Reotemp and took recordings of:

    • measurements for conveyor belt

    • measurements for gauge holder

    • measurements for pressure gauges with various dimensions

    • pictures for wiring of sensor

    • pictures for wiring of PLC

• Revised design of CNC pillow bearing block

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Find and buy the appropriate heating tape (tech specification research) - Desi

  • Find and buy the appropriate array of sensors (tech specification research) - Ethan

    • Conceptualize sensor integration

  • Gauge holder follow-up and preparation for assembly - Elaine

    • Revise drawings for CNC parts

    • Research different vendor/manufacturer options for funnels

  • Test the Arduino code (interface between PLC and Arduino) - Justin

    • Familiarize with existing wiring diagram and any changes needed

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

4/17/20 Zoom Meeting with Eric

• • Presented progress updates for sponsor; presentation attached below

  • Sponsor allowed for arduino and controllino methods

  • Sponsor did not recommend the drum heater (250 gal) method

    • the current system consists of an electric tank of water heater

    • recommends trying the heating tape instead

• Sponsor seems to allow to try out the diffuse sensor

• Sponsor noted that some gauges have different volumes with the same diameter

  • • (potential issue to fix for automatic gauge detection)

4/17/20 Email with Eric

• • Wanted the biggest gauges to be filled in 1-2 minutes

  • Wanted the black case gauge with pause needed for settling to be filled in 3-5 minutes

4/17/20 Email with Eric (with comments from Mike)

• • Suggested redesign for CNC pillow block bearing

    • minimize curves

    • stick to making holes and tapping threads

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

4/13/20 Meeting with Professor Tustaniwskyj

• • Instructor advised that if the purchased don't get approved quickly, reach out directly to himself

  • Instructor advised that adhesives on the conveyor loop would catch dust

    • Spray on requires a lot of work and may ruin other mechanism of the belt

• Instructor recommends using high friction belt

• Instructor asked about the precision of temperature control of fluid coming out

• Instructor advised of using a reflective on the bearing block for automatic gauge size detection

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • N/A

Risks and Areas of Concern

• • Automatic gauge detection

    • Some gauges have the same dimension but with different volumes. Therefore, with just an array of sensors, it would be hard to differentiate the gauge type hence giving an accurate fill.

Resources or Information Required but not Available

• • PLC Logo V8 Basic! 

    • Online downloadable only has the demo version that crashes when the application starts

    • Installation guide with CD is at ReoTemp's facility

Schedule

• • Week 5 Monday: Proof-of-Concept Presentation (next week)

  • Gantt chart is updated

Budget (list amount spent and amount remaining)

• • Budget Spent: $1776.90

  • Amount remaining: $8223.10

Progress on Report and Webpage

• • Completed second draft of sections of report:

    • Impact of Society

    • Professional Responsibility

• Updated objectives section of webpage home page
