    • A sheet feeding mechanism for feeding stacked sheets one by one from a sheet magazine includes a plurality of suction cups coupled to a vacuum suction device for attracting one sheet at a time, and an arm member on which the suction cups are securely mounted. At least one rotatable bearing is operatively coupled to the arm member and rollingly movable in a guide groove having at least one curved or bent guide opening. The bearing is movable by a slider in and along the guide opening to angularly move the arm member and hence the suction cups for thereby swaying and feeding a sheet held by the suction cups.
    • 用于从片材盒一个接一个地堆叠的片材的片材进给机构包括:一个联接到真空吸引装置的多个吸盘,用于一次吸引一个片材;以及臂部件,其上安装有吸盘。 至少一个可旋转轴承可操作地联接到臂构件并且可在具有至少一个弯曲或弯曲的引导开口的引导槽中可滚动地移动。 轴承可以通过滑动件沿着导向开口移动,以便使臂构件和因此的吸盘角度地移动,从而摇摆并进给由吸盘保持的片材。
