Solutioning tolerance, plus or minus ten percent. Work the four drills with the guide's reference inputs, then stress-test the flow. Don't run the sorter tab or spur speed. That's Lesson 25.
Your reference. The Calc Logic Guide is the formula authority.
Four problems, all on the guide's own reference numbers. Show the substitution, then the answer.
A belt accelerates from SpeedIn 60 to SpeedOut 120. Carton length L 20 in, starting gap 24 in. What gap forms after the speed change?
120 x (20 / 60) - 20 + 24 = ?At SpeedIn 60 FPM, carton length L 20 in, starting gap 24 in. What's the maximum cartons per minute?
60 / ((20 + 24) / 12) = ?Gap 44 in, carton length L 20 in. What's the center-to-center pitch?
44 + 20 = ?Sanity-check 20 CPM with the standard case: SpeedIn 60, carton length L 13 in, starting gap 24 in. Then decide: does it clear 20 CPM with margin? If not, name your levers.
60 / ((13 + 24) / 12) = ?Trace your flow under each condition. No calculation. If a question stumps you, you found a hole in the flow, not your explanation.
A wave releases and every zone fills at once. Does each section absorb the surge?
A downstream station slows. Does upstream accumulation absorb it, or does it reach induction?
Volume grows twenty or thirty percent. Is there headroom, or is the system saturated?
Combined flows both peak together. Is the conflict structural?
An exception is handled manually. Is there a path that doesn't block the main flow?
