    • A process and apparatus for automatically changing the stack of sheets in a sheet-fed printing machine is disclosed comprising sheet-carrying surfaces, sheet-separating devices, a pallet, sensors and a control system. The sheet-carrying surfaces act in concert with the sheet-separating devices to create an auxiliary stack separate from the existing stack of printed sheets. In this manner, the existing stack of sheets are removed and the auxiliary stack is deposited on a new stack base as brief and as closely coordinated as possible. The timing of the transition from the sheet-separating devices to the sheet-carrying surfaces is coordinated such that, even in the case of thin printing materials, the stack changing apparatus functions properly during the stack-changing process.
    • 公开了一种用于自动更换单张纸印刷机中的纸张堆叠的方法和装置,其包括片材承载表面,片材分离装置,托盘,传感器和控制系统。 片材承载表面与片材分离装置一致地产生与现有的打印片材堆叠分离的辅助叠片。 以这种方式,现有的纸堆被去除,并且辅助堆叠被沉积在新的堆叠基底上,并且尽可能地紧密配合。 协调从片材分离装置到片材承载表面的转移的定时,使得即使在薄的印刷材料的情况下,堆叠更换装置在堆叠改变过程中也能正常工作。
