Description

Conveyor Assembly for Autonomous Mobile Robot The present invention relates to a conveyor assembly for an autonomous driving robot, and more specifically, to a conveyor assembly for an autonomous driving robot that is positioned on an autonomous driving robot moving autonomously to transport a transported object. Recently, there has been an increasing trend of deploying autonomous robots for logistics transport in industrial sites. Although autonomous robots go by various names such as AGV (Autonomous Guided Vehicle) and AMR (Autonomous Mobile Robot), they are used in similar ways in the industrial sector for logistics transport. Autonomous robots move along a pre-set path and perform the task of transporting, that is, unloading. For example, if an autonomous robot sets a path from point A to point B in advance, it loads the goods at point A and moves to point B. Meanwhile, in the unloading operation of a transported object using an autonomous robot, the object is loaded onto the autonomous robot at one point using a worker's operation or equipment, and then the autonomous robot moves to another point according to pre-set information. Subsequently, the loaded object is unloaded from the autonomous robot using a worker's operation or equipment. Specifically, for example, the autonomous robot can transport the object from point A to point B, from point B to point A, or continuously transport the object between points A and B. However, conventional methods for transporting materials using autonomous robots have problems in that they require the process of unloading materials using human labor or separate equipment, which not only increases the transport time but also causes musculoskeletal disorders and work-related risks for workers.
