Abstract:
1. An accumulating and delivering apparatus for feeding cardboard sheets one by one, each cardboard sheet having a lower surface, comprising: a plurality of stacking bases for stacking said cardboard sheets thereon; a stacking base driving means for moving said stacking bases in a vertical direction between a stacking position for stacking said cardboard sheets on said stacking bases in a form of a group and a delivering position for delivering said group of said cardboard sheets formed on said stacking base; a ledge for supporting the lower surfaces of said cardboard sheets being fed when said stacking base is moved out from its stacking position, said ledge being a single ledge always maintained at a desired level located between a level corresponding to said stacking position and a level corresponding to said delivering position, wherein said stacking bases comprise at least one pair of stacking bases, each of said pair of stacking bases being moveable between said stacking position and said delivering position via a path including an ejecting position located rearwardly from said stacking position with respect to the feeding direction of said cardboard sheets, wherein when one of said stacking bases is moved from said ejecting position to said stacking position, said one of said stacking bases moving to said stacking position ejects said group of said cardboard sheets previously formed on another one of said stacking bases by pushing it out forwardly in a direction with respect to the feeding direction of said cardboard sheets, and wherein said stacking base driving means moves said stacking bases in such a manner that when one of said stacking bases is moved away from said stacking position, another of said stacking bases is moved into said stacking position and that said stacking bases are kept offset to each other in the sheet feeding direction.
