Abstract
A conveyor system having a conveyor path and friction drive spaced along the path to drive carriers along the path. Each friction drive is controlled by a drive controller, which communicates tracking, routing, and other information directly to other drive controllers within range via a wireless signal. The drive controllers may also directly communicate wirelessly with a central controller. If the central controller or a desired destination drive controller is out of range of a particular drive controller, that drive controller may communicate through other drive controllers until the desired destination drive controller is reached, or a drive controller that is within range of the central controller is reached.
