Weighing, Dosing & Loss-in-Weight Feeding worked example

Line Speed Matching at 99% feeder-to-line synchronization efficiency: a worked example

Push feeder-to-line synchronization efficiency up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when line speed matching in weighing, dosing and loss-in-weight feeding is being committed and you need a throughput number you can defend.

The inputs for this scenario

  • Finished linear feet produced this run: 1,200 units (unchanged)
  • Conveying line runtime: 8 hr (unchanged)
  • Feeder-to-line synchronization efficiency: 99 % (raised for this scenario; the documented default is 90)

Working through the calculation

  • Applying the documented formula (Raw line speed matching = completed output รท runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 149 ft / min for effective throughput, the number this scenario is built around.
  • At this operating point the engine returns 150 ft / min for raw throughput.
  • At this operating point the engine returns 99 % for efficiency.
  • At this operating point the engine returns 8 hr for runtime.

How this compares with the baseline

  • Against the tool's baseline example, where feeder-to-line synchronization efficiency sits at 90% and the headline result is 135 ft / min, this scenario comes in 10% above the baseline at 149 ft / min.
  • It computes effective line speed in ft/min by dividing finished output by runtime, then multiplying by the feeder synchronization efficiency. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
