A ream collection lift table and asssociated transfer conveyor system are contained in a unitary assembly which is mounted beneath a sheet discharge end of a sheeting machine. The lift table portion utilizes a scissors-elevating structure for reciprocating a sheet collection surface. The elevating structure includes criss-crossed, collapsible scissors arms, each provided with shaped profile surfaces for engagement with a laterally movable roller driven at constant speed, whereby the collection surface descends at varying rates. At a lowermost position, the collection surface deposits a collected ream onto a laterally directed belt conveyor, positioned intermediately of the integral assembly. The belt conveyor deposits the collected ream onto the receiving surface of an orthogonally directed slat conveyor for transferring the ream to a cartoning station off to one side of the sheeting machine. The slat conveyor is formed with slat chains, the upper portion of which is movable between a lowered, slanted, ream-receiving and an elevated, level, ream-conveying position. Structure for positioning the upper portion of the slat chain includes a reciprocated chain guide member formed underneath with slanted profile surfaces which ride over ramped support walls. |
