    • A mechanism for stacking and weighing sheets fed from a semi-continuous sheet cutter. The mechanism includes a hydraulic cylinder operatively connected to a stacking table so that as sheets are deposited onto the stacking table, the table is lowered by indexing the hydraulic cylinder. This continues until a full stack of sheets, having a predetermined number of sheets determined by weight, by height of the stack or by sheet count has been stacked on the table. The hydraulic cylinder comprises a hydraulic fluid reservoir, an electrically driven hydraulic pump, a four-way, three position hydraulic spool valve, a hydraulic cylinder and back pressure safety valve. A load cell connected between the hydraulic cylinder and the rest of the mechanism is connected to a scale device which will weigh the stack of sheets.
    • 用于堆叠和称重从半连续片材切割机进给的片材的机构。 该机构包括可操作地连接到堆叠台的液压缸,使得当片材沉积在堆叠台上时,通过对液压缸进行分度而降下工作台。 这一直持续到具有按重量确定的预定数量的片材,堆叠高度或片材数量的整堆片材已经堆叠在桌子上。 液压缸包括液压油箱,电动液压泵,四通三位液压滑阀,液压缸和背压安全阀。 连接在液压缸和机构的其余部分之间的称重传感器连接到称重装置上,该称重装置将对纸叠进行称重。
