摘要： A sheet stacking system includes a conveyor having a discharge end, a hopper at the discharge end configured to receive the sheets ejected from the discharge end and guide the sheets as they fall in a cascade path onto a platform associated with the hopper, the falling sheets forming a main stack on the platform, the hopper including a backstop facing the discharge end of the conveyor such that the sheets ejected from the discharge end impact against the backstop before forming the main stack, and a first accumulator having at least one first support extending through the backstop and shiftable from a retracted position to an extended position, the at least one first support being movable vertically relative to the backstop in the extended position from a raised location outside the cascade path to a lowered location in the cascade path.
