Abstract: A document-handling apparatus and method for transporting documents along a document feed path from an upstream end to a downstream end. The apparatus includes at least one document-handling subassembly along the document feed path for singulating the documents, controlling gaps between the documents, and conveying the documents toward the downstream end; a sensor mounted along the document feed path for sensing the positions of the documents and for generating position signals based on the document positions; and a control apparatus for receiving the position signals and for controlling the velocity and acceleration of the document-handling subassembly so as to regulate the size of the document gaps and to maximize document throughput. The document-handling subassemblies can include a stack advance mechanism, an input feeder, one or more singulators, and one or more output feeders. A trap can also be included to stop a document along the feed path. The apparatus can operate at accelerations as low as 0.5 g, enabling documents to be transported with constant motion through the apparatus, thereby maintaining efficient inter-document gaps without using high accelerations.

Abstract translation: 一种文件处理装置和方法，用于将文件沿着文件馈送路径从上游端传送到下游端。 该装置包括沿文件馈送路径的至少一个文档处理子组件，用于分离文档，控制文档之间的间隙，并将文档传送到下游端; 传感器，其沿着文件馈送路径安装，用于感测文档的位置，并且用于基于文档位置产生位置信号; 以及用于接收位置信号并用于控制文档处理子组件的速度和加速度的控制装置，以便调节文档间隙的尺寸并最大限度地提高文档的吞吐量。 文档处理子组件可以包括堆栈提前机构，输入馈送器，一个或多个分离器以及一个或多个输出馈线。 还可以包括陷阱以沿着馈送路径停止文档。 该设备可以在低达0.5g的加速度下工作，使文档能够通过设备恒定运动，从而在不使用高加速度的情况下保持有效的文档间间隙。
