The PES pacing wheel is a rotating wheel that mounts onto the PES side rail system. It is designed to evenly space containers as they pass by the wheel. The wheel turns at a speed slower than the conveyor is traveling and slows a container as it passes by the wheel. It comes standard with a variable speed controller to set the distance between containers.
The PES pacing wheel is often combined with a sensor system that will stop and start the wheel when given conditions are met. This can be useful for line control and product handling.
