Read the names first, from memory. Then run the weight-per-foot gate on the Riverside cartons. Then walk the flow and write your map.
Five things off a drawing. For each, write the category, transportation or accumulation, and in a word or two say what the name told you. Remember the caveat: this naming is Hytrol's, and every maker sells the same categories under its own letters.
| On the drawing | Category (T or A) | What the name told you |
|---|---|---|
| 190-E24EZ | ||
| ABLR | ||
| ABEZ | ||
| NSP | ||
| A sorter |
Before you can hand a point to motor-driven roller, the load has to clear the platform's rating. Weight per foot is carton weight divided by its length in travel in feet, and the worst case is the heaviest carton at the shortest length, not the average. These are your four Riverside cartons from the requirements work. Convert each carton's length in travel to feet (inches divided by 12), then compute weight per foot for each. Circle the worst case.
| Carton | Weight | Length in travel (in) | Weight per foot (compute) |
|---|---|---|---|
| Small Case | 3 lbs | 8 in | |
| Standard Case | 12 lbs | 13 in | |
| Tall Case | 18 lbs | 10 in | |
| Large Case | 28 lbs | 22 in |
Worst-case carton and its weight per foot: ________________________. Does it clear the motor-driven-roller rating you'd be checking against? If it doesn't, MDR is out at that point, and you don't argue with a hard limit.
Read the layout, then mark every point that has to hold product before you name a single conveyor, and say which mechanism the building points you toward.
Product comes off two pick lines onto a spine, runs to a single merge, then to a scan point, then into a sorter with three takeaway spurs to three dock doors. The building shares one air compressor with production, and it dips at peak. Maintenance is one person, reactive only.
Mark every point where product may have to wait, transportation or accumulation, and name which accumulation mechanism the air and the maintenance reality point you toward. Then say what number you'd run before you defend the choice.
