<p>A conveyor and methods for turning cases. The conveyor includes a pair of side-by-side belts running preferably at different speeds. The different belt speeds cause the leading edge of a package straddling both belts to move toward the slower belt. The two belts include transverse rollers that can be selectively actuated in a series of actuation zones along the conveyor to push packages conveyed atop them to the right or to the left. A controller controls the actuation of the belt rollers in each zone sequentially so that the belt rollers supporting the leading edge of the package push it towards the slower belt and the belt rollers supporting the trailing edge of the package push it towards the faster belt to accelerate the turning of the package as the belts advance.</p> |
