Abstract
An improved pneumatic control for a zero pressure accumulating conveyor includes, in a discharge zone control, a first control valve and a master control valve cooperating to produce an accumulating function for one position of the master control valve, and a continuous discharge zone operation for a second position of the master control valve while all loaded upstream zones operate sequentially upon clearing of their respective adjacent downstream zones. Accumulated items in the discharge zone and in the next upstream zone are sequentially, and not simultaneously, conveyed upon movement of the master control valve to its second position.
