摘要： Sheet stacking apparatus having a variable speed conveyor on which sheets are carried in partially overlapped or "shingled" relation and deposited onto a second variable speed conveyor disposed in end-to-end relation to the first conveyor for receiving sheets therefrom and projecting onto a vertically movable stacking conveyor which lowers automatically as the stack builds up. Feed stop mechanism is disposed to stop and release selectively the flow of sheets from the first conveyor onto the second conveyor in response to the "full stack" position of the stacking conveyor. Control means is provided for changing the speed of the two conveyors in sequential relationship to the actuation of the stop mechanism whereby the speed of the first conveyor is substantially reduced, while the speed of the second conveyor is substantially increased to clear the latter preparatory to discharge of the stacking conveyor. Control means also operates to release the stop mechanism and return the conveyors to normal speed upon return of stacking conveyor to sheet receiving position.
摘要翻译：具有可变速度输送机的纸张堆垛装置，纸张在其上以部分重叠或“带状”关系的形式被携带，并且沉积到与第一输送机成端对关的第二变速传送机上，用于从其接收纸张并垂直投影可移动堆垛输送机随着堆栈的积聚而自动降低。进给停止机构设置成响应于堆叠输送机的“全堆”位置，将片材的流动从第一输送机选择性地停止并释放到第二输送机上。提供了控制装置，用于以与停止机构的致动顺序关系的方式改变两个输送机的速度，从而使第一输送机的速度大大降低，同时第二输送机的速度基本上增加以清除后者的准备放电的堆垛输送机。控制装置还用于释放停止机构并在将堆垛输送机返回到纸张接收位置时将输送机返回正常速度。
