Abstract: A measurement system used in conjunction with a conveyor includes a first sensor with a first transceiver and a second sensor with a second transceiver. The transceivers transmit a first light beam and a second light beam towards a movable portion of the conveyor. A control unit communicably coupled to the first sensor and the second sensor, wherein the control unit calculates a first distance between the first sensor and the movable portion based on the first sensor and a second distance between the second sensor and the movable portion based on the second sensor. The control unit determines a difference value between the first distance and the second distance; and stops the unloader in response to the difference value being above a predefined threshold value.

Abstract: A self-aligning interface (6300) is attached to a robotic carton unloader (6100) and provides an interface between an extendable conveyor (6200) and the robotic carton unloader (6100). The self-aligning interface (6300) can include a positional measurement device (6320, 6320b, 6320c) mounted on the robotic carton unloader (6100) and operatively engaged with the extendable conveyor (6200) to provide positional information about the location of the extendable nose conveyor (6220) relative to the positional measurement device (6320, 6320b, 6320c). A control unit (6180) is attached to the robotic carton unloader (6100) for full robotic control of robotic carton unloader (6100) and the unloading process. The control unit (6180) is connected to the positional measurement device (6320, 6320b, 6320c) and the extendable conveyor (6200).
