Abstract
An accumulating conveyor system for transporting a series of loads includes a series of conveyor zones including at least an upstream conveyor zone and a downstream conveyor zone. Each conveyor zone includes a drive arrangement for operating the conveyor zone to advance loads therealong. An improved singulated release control is interconnected with each drive arrangement. The control is operable to advance adjacent first and second loads on adjacent upstream and downstream conveyor zones, respectively. The control is operable to stop operation of the upstream zone to maintain the second load stationary, while continuing operation of the downstream zone to advance the first load. When the downstream load approaches the downstream end of the downstream conveyor zone, the control is operable to resume operation of both the downstream and upstream conveyor zones, to continue advancement of the first and second loads, respectively. In this manner, the first load is discharged from the downstream zone while the second load is advanced from the upstream conveyor zone onto the downstream conveyor zone, to maintain a single load per zone ratio while providing a more compact arrangement of loads on the conveyor zones.
