Abstract
A safe tiltable sheet feeding apparatus including a tiltable sheet support tray having a lead edge and a trail edge, for supporting a stack of sheets to be fed lead edge first from the stack. The tiltable sheet feeding apparatus also includes a feed head adjacent the sheet support tray for feeding a top sheet of the stack from the stack and an elevator assembly for independently raising, lowering and tilting the trail edge of the sheet support tray. The elevator assembly includes elevator drive motors, a controller, side frames defining lead edge elevator slots, and trail edge elevator slots. Importantly, the tiltable sheet feeding apparatus includes an overtilt safety sensor device mounted within the trail edge elevator slots and connected to the controller, for sensing overtilt of the trail edge of the sheet support tray, and for preventing resulting damage to the tiltable sheet feeding apparatus.
