<p>An endless belt conveyor system has patterned belt transport surface for engaging loads having spaced protrusions on their bottom surfaces, such as, for example, multi-wheeled carts. The endless belt is trained over a pair of rollers, and has a plurality of nesting means on its transport surface designed to match and engage the protrusions on the bottom of the loads. As each approaching load is identified, the belt speed is controlled so that the nesting means on the belt surface engages the protrusions on the loads for securely engaging the loads during their transportation from one station to another. Different patterned belt transport surfaces are provided for engagements of the different protrusions of the loads with corresponding nesting means on the surface of the belt during the transportation of the load.</p> |
