    • An ingestion assembly is provided for a singulating apparatus having a conveyor system for moving a stack of sheet material along a feed path. The ingestion assembly is spatially positioned above the conveyor belt and includes at least one singulating roller driven in a direction opposing the motion of the conveyor belt. The ingestion assembly comprises an assembly support rotationally mounting the singulating roller at a downstream end portion and pivotally mounting to the singulating apparatus at an upstream end portion. A movable guide mounts to the assembly support and is positionable relative thereto as a function of a force vector imposed on the guide by the sheet material. Additionally, the moveable guide includes a surface operative to guide the sheet material into a singulating interface which is formed between the singulating roller and the conveyor system. In operation, sheet material enters the throat of the ingestion assembly and contact is made with the moveable guide. When the force vector, imposed by the sheet material, is less than a threshold level, the guide assumes a first position operative to shingle sheet material in preparation for singulation by the singulating roller. When the force vector, is greater than the threshold level, movable guide assumes a second position operative to pivot the assembly support and increase the singulating interface. Consequently, sheet material having a larger thickness dimension may pass for separation by the singulation apparatus.
    • 提供了一种用于具有用于沿着进给路径移动片材的堆叠的输送机系统的单独设备的摄取组件。 所述摄入组件在空间上位于所述传送带上方,并且包括至少一个单独辊,所述至少一个单独辊沿着与所述传送带的运动相反的方向驱动。 所述摄取组件包括组装支撑件,所述组件支撑件将所述单个定位辊旋转地安装在下游端部处,并且在上游端部处可转动地安装到所述分离设备。 可移动导向件安装到组件支撑件上并且可以相对于其定位,作为由片材材料施加在引导件上的力矢量的函数。 另外,可移动引导件包括可操作地将片材引导到形成在单分离辊和输送系统之间的单一界面中的表面。 在操作中,片材进入摄入组件的喉部,并与可移动导板接触。 当由片状材料施加的力矢量小于阈值水平时,导向件采用第一位置,其操作以将片材材料混合在一起以准备通过单分离辊进行单分割。 当力矢量大于阈值水平时,可移动导向件呈现第二位置,可操作以枢转组件支撑并增加单个界面。 因此,具有较大厚度尺寸的片材可以通过分离装置进行分离。

    • A method and a system are disclosed for adaptively controlling a stepper motor to produce a required torque output based on selection information provided by a sensor or a user/user interface which, in combination with a selector, selects a torque-related value. The selection information provided to the selector for selecting the stepper motor torque-related value may be, for example, the size or thickness of material being handled or the number of accumulated sheets for processing. The torque-related value is predetermined through experimentation and loaded into a lookup table stored in the memory of a motion control system board. The selected torque-related value is provided to a stepper motor driver which supplies the appropriate drive signal(s) to the stepper motor.
