    • A device for singly separating stacked sheet-like elements, includes at least one sucker for applying vacuum, the sucker being deformable for varying the volume thereof, and a vertically and rotatably displaceable holder formed with an inner air duct and having a lower end at which the sucker is disposed. Further included are a closure device controllable in accordance with a given operating cycle for opening and closing the air duct, a drive device for vertically and rotatingly displacing the holder, a support operatively coupled with the drive device and having a guide device for guiding the displaceable holder substantially perpendicularly to a suction surface of the sucker and between respective stops at spaced-apart locations of the guide device, and a resilient device for biasing the holder in a direction towards a lower end position thereof. Moreover, the holder is formed with a sensing surface at the lower end thereof and within the deformable sucker for cooperating with an upper surface of a respective uppermost sheet-like element of a stack of sheet-like elements.
    • 用于单独分离堆叠的片状元件的装置包括至少一个用于施加真空的吸盘,所述吸盘可变形以改变其体积,以及形成有内部空气管道的竖直和可旋转移动的保持器,并且具有下端, 吸盘被设置。 还包括根据用于打开和关闭空气管道的给定操作循环可控制的闭合装置,用于垂直和旋转地移动保持器的驱动装置,与驱动装置可操作地联接的支撑件,并具有用于引导可移动的 保持器基本上垂直于吸盘的吸入表面并且在引导装置的间隔开的位置处的相应止动件之间,以及用于沿着朝向其下端位置的方向偏压保持器的弹性装置。 此外,保持器在其下端处形成有感测表面,并且在可变形吸盘内形成有用于与片状元件的堆叠的相应最上面的片状元件的上表面配合。
