Abstract
An unstacking apparatus includes a feed conveyor for feeding stacks of items, and a decline unstacking section including at least first and second declined conveyors arranged in series. A stack of items being transferred from the feed conveyor to the first declined conveyor tilts forwardly to cause the items to slide forwardly off one another into a shingle arrangement on the first declined conveyor. The second declined conveyor includes an upstream end which is offset upwardly relative to a downstream end of the first declined conveyor, causing items to travel upwardly in order to pass from the first to the second declined conveyors. The second declined conveyor travels at a faster speed than the first declined conveyor for at least partially de-shingling the items. A transfer conveyor conveys items to an incline unstacking section which includes at least first and second incline conveyors arranged in series. A stack of items being transferred from the transfer conveyor to the first inclined conveyor tilts rearwardly to cause the items to slide rearwardly off one another into a shingle arrangement on the first inclined conveyor. The second inclined conveyor includes an upstream en…
