Abstract
The invention provides an improved live roller conveyor system for preventing damage to conveyed cases of goods when stopped upon live rollers. In an embodiment of the invention, a live roller comprises a drive shaft with a plurality of roller members rotatably affixed thereto. One or more bushings are provided between an inner surface of each roller member and an outer surface of said drive shaft. When a conveyed case is stopped along the conveyor, for example, during case layer formation for loading onto a pallet, the rollers underneath the case stop rotating relative to the drive shaft due to slippage between the bushings and drive shaft.
