Line Balancing

We match conveyor speed, carrier pitch and station layout to your takt time, so every station gets the right amount of time and no carrier waits without reason.

From Takt Time to Conveyor Speed

Line balancing starts with takt time: the time available per unit to meet demand. The conveyor then has to deliver one carrier per takt to each station.

Conveyor speed = carrier pitch ÷ takt time

Example: at 30 jobs per hour the takt is 120 seconds. With a 6 m carrier pitch, a continuous line must move at 3 m per minute. For stop-and-go lines, EMS carriers move fast between stations and stop for the work content.

We also plan for model mix, where different products need different work times at the same station.

How We Do It

Tools for a Balanced Line

  • Throughput calculation

    Jobs per hour, pitch, speed and station count calculated before design.

  • Continuous or indexing

    Moving-line assembly or stop-and-go stations, chosen per process.

  • Variable speed zones

    EMS carriers slow down in work zones and speed up in transport sections.

  • Model mix support

    Parallel stations and bypasses for products with longer work content.

  • Buffer placement

    Small buffers between zones to absorb variation in work time.

  • Simulation

    Flow checks of the layout before steel is cut, to confirm the target output.

FAQ

Frequently Asked Questions

What is takt time?

Takt time is the available production time divided by customer demand. For example, 3,600 seconds per hour divided by 30 units gives a takt of 120 seconds.

How do you calculate conveyor speed?

For a continuous line, divide the carrier pitch by the takt time. A 6 m pitch at a 120-second takt gives 3 m per minute.

How do you handle different products on one line?

With model mix planning: parallel stations, bypasses and variable speed zones give longer work content more time without slowing the whole line.
