156B Week 10

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

• • Base-plates are completed and ready to be tested, waiting on the rest of the gauge holders to be fabricated

  • Most necessary hardware parts have been ordered and shipped and majority have been assembled

  • Official testing (presented in the lab reports) are to be done Week 10

    • test different glycerin fill time with changes in temperature, spout length, and peristaltic speed

Accomplishments from Previous Week

• • Put guide rails in the first conveyor with rivets

  • Built second roller tracks

  • Put the high friction belt on both powered conveyors

  • Tested out full loop capacity (can fit 49 gauge holders)

  • Electronic boxes were taken apart, relabeled, rewired, and put together 

  • Terminal blocks were added

  • Remounted thru beam (high friction belt had the holders offset)

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

• • Members: Desi, Elaine, Ethan 

  • Highest Priority:

    • Get loop running smoothly

      • second loop drill holes, add rivets, add PTFE material for guide rails

  • Adjust thru-beam sensor to make it more reliable 

  • Integrate heating tape

  • Integrate temperature probe

    • Calibrate the PLC code pump parameters using glycerin liquid weight

• Medium Priority:

  • Mount the heating tape thermostat control semi-permanently

  • Mount the read-out part of the temperature probe semi-permanently

  • Change Arduino power source to integrated PLC

    • Connect fan to power

    • Get good data on funnel overflow

• Low Priority:

  • Add panel-mount AC power receptacle for the heating tape to plug in to

  • Automate Size Detection (Justin & Ethan) *Secondary objective

    • Confirm paint colors can be calibrated adequately

    • Test PLC integration

      • create color-testing PLC code with low-volume amounts for each "color"

  • Mount the color sensor and re-calibrate in position

  • Mount the I/O board inside the electronics box

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

• • Meeting with ReoTemp 5/29/20 (Eric and Brian)

    • Updated on full loop being assembled and 1 gauge stand being fully built

    • Sponsor was excited for us to fully build the system Week 10

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

• • N/A

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

• • Team 15's comments on 

    • Website:

      • Add photos of ourselves

      • Annotations are too small and fuzzy

      • Label figures

      • unclear phrasing and references to previous Spring Team 

      • Background, objectives, and final design are well written

  • Report (general comments):

    • • Add images and figures shown in presentation but not in the report

      • Put annotations on figure sin the same font and size as the rest of the text

      • Keep tenses consistent

      • Keep Indentation style consistent

Risks and Areas of Concern

• • Automation color detection might not work after applying the PLC code (debugging would probably have issues). Depending on if the team has made progress in primary objectives then the team will see if the secondary objective is attainable

Resources or Information Required but not Available

• • N/A

Schedule

• • Described upcoming milestone

  • Updated Gantt chart.

Budget (list amount spent and amount remaining)

• • Spent: $5636.57

  • Remaining: $4363.43

Progress on Report and Webpage

• • Will make revisions on report and webpage as suggested by Team 15
