How do I calculate the conveyor speed I need to hit my rate?

Required line speed depends on target parts per hour and part spacing (pitch). If you need 600 parts per hour at 12-inch centers, that is 600 pitches of one foot per hour, or 10 feet per minute. The Required Line Speed and Conveyor Speed calculators handle this, and Conveyor Parts Per Hour lets you check the reverse: how many parts a given belt speed and spacing actually deliver.

How do I size a conveyor for a required dwell time?

Zone length equals conveyor speed times required dwell. A part needing 8 minutes of wash at 10 feet per minute needs 80 feet of wetted zone. Conveyor Length from Dwell Requirement calculates this directly, and Dwell Time confirms how long parts sit in an existing zone at a given speed. If the zone will not fit, you lower line speed or add stages.

What buffer size do I need between two stations?

Buffer size depends on how long the downstream station can go down before it starves the upstream one, times the production rate. If the constraint recovers in 4 minutes at 30 parts per minute, you need roughly 120 parts of accumulation. Buffer Size and Accumulation Capacity size this, decoupling stations so a short stop does not cascade into full line downtime tracked by Downtime Cost.

How do takt time and line speed relate?

Takt time is available time divided by demand, the pace you must complete one unit to meet the schedule. Line speed then follows from takt and part spacing: at a 6-second takt with parts on 10-inch centers the belt must index one pitch every 6 seconds. Use Takt Time to set the pace, then Conveyor Pitch Time and Required Line Speed to convert it into belt velocity.

How do I find and fix the bottleneck on my line?

The bottleneck is the station with the longest cycle time relative to takt; it caps the whole line. Bottleneck Capacity identifies the constraint's maximum output, and Station Cycle Time plus Work Content show which station exceeds takt. Line Balance redistributes work across stations to level cycle times, and Buffer Size protects throughput around a constraint you cannot eliminate.

How many operators does my conveyor line need?

Staffing comes from total work content divided by takt time, rounded to whole operators, then adjusted for stations that cannot be split. If work content is 90 seconds and takt is 30 seconds, you need at least three operators. Conveyor Operator Staffing and Work Content calculate the headcount, and Line Balance confirms each operator's load stays under takt without idle time.

Manufacturing calculator category

Conveyor & Production Line Design calculators

This category covers the design math for conveyors and flowlines: how fast the belt runs, how far apart parts sit, how long they dwell in a process zone, and how much buffer you need between stations. It is for line designers, industrial engineers, and production planners sizing capacity before they commit to a new layout or schedule.
