Abstract
A control system for an accumulating conveyor having a plurality of zones wherein each zone has a pneumatic logic module that includes a relay limit valve and one or more OR valves. The output of one OR valve is connected to air actuators which affect driving engagement and disengagement of drive rollers with the load carrying rollers of a zone of the conveyor. A pilot operated relay valve is connected to the discharge zone of the conveyor and employed to release an article thereon. The control system can easily be modified to provide accumulation in either direction, as well as single, sequential or train release in both directions.
