Abstract
A control system for an accumulating conveyor having a plurality of zones, wherein each zone includes an improved pneumatic logic module comprising a relay limit valve and an AND valve, the output of the AND valve being connected to a driving input of a fluid motor for transmitting power to the corresponding zone of the conveyor. A pilot operated relay valve is connected to the first zone and employed to release an item thereon. The control system can be easily modified to provide forward or reverse accumulation, and single or train release. Additional pilot operated relay valves are employed for selecting between forward and reverse accumulation and single additional pilot and train release modes.
