Conveyor with twin bias accumulation

摘要

A conveyor system comprises a power and free central power track for receiving lead trolleys of a carrier and a pair of free tracks positioned on opposite sides of the power track for alternatively receiving trailing trolleys of the carriers such that the carriers are twin biased accumulated or banked in side-by-side relationship to one another on opposite sides of the power track. A switching mechanism is provided to control switching of the lead and trailing trolleys from a feed track to the appropriate power track or free track.
