Conveyors calculator

Part Spacing Conveyor Speed Calculator

Use this calculator when deciding whether a proposed product pitch will fit the target production rate. It is useful for belt conveyors, indexing fixtures, inspection conveyors, and packaging lines where spacing drives speed, sensors, reject timing, and downstream handoff windows.

What this calculator does

  • Check the belt or line speed implied by a target output and proposed product spacing.
  • a line layout planner needs to test whether the planned part spacing forces the conveyor above its practical speed range
  • The result shows whether the proposed product spacing drives a realistic conveyor speed.

Formula used

  • Required throughput rate = target output ÷ spacing efficiency
  • Required belt speed = required throughput rate × proposed spacing ÷ 720

Inputs explained

  • Target finished-part output: Use the required good-part output for the conveyorized process window.
  • Proposed leading-edge part spacing: Measure pitch from one product leading edge to the next, including clearance.
  • Expected spacing efficiency: Use less than 100% when gaps, missed loads, or variable product presentation are expected.

How to use the result

  • Use it while setting guides, sensors, photoeyes, reject spacing, or product pitch for a new SKU or layout.
  • It checks the speed required by the spacing assumption; it does not calculate the minimum mechanical gap for unstable, tipping, or rotating products.

Common questions

  • What is Part Spacing Speed Check for? Check the belt or line speed implied by a target output and proposed product spacing.
  • What information do I need before using it? You need target output in parts per hour, proposed product pitch in inches, and a realistic spacing efficiency.
  • When is the result only an estimate? The result is only as good as the pitch measurement and efficiency assumption; real product skew, merges, and starts/stops can require larger spacing.
  • How can I use the result on the line? Use the speed result to decide whether to tighten spacing, slow the target rate, add lanes, or change conveyor hardware.
