Abstract
A mattress storage and sorting conveyor, which discharges to one or more extendable conveyors, has a feed section that collects the mattress from one or more wrappers and inserts the mattress onto a circulating system which stores the mattresses until ready to be transferred. A short length of the circulating system may be repositioned to discharge a particular mattress to one or more conveyors that transport the mattress to a respective extendable conveyor. An operator at a control station selects which mattress to discharge from the circulating system. The conveyor system is controlled by a series of sensors, relays, and motor controllers to prevent or minimize the collisions between mattresses on the circulating system of the conveyor.
