Abstract: An assembly and method thereof creates a stack of objects. The assembly has a diverted to move objects having a desired size from a first conveyor to a second conveyor. The diverted utilizes diversion plates. The second conveyor transfers the objects to an accumulator. The objects that are accumulate are squared and then moved to a raised position. A lift assembly then lifts the accumulated objects that were square and translates the objects to a queuing assembly. The process repeats to construct a stack of objects with multiple layers of objects. The created stack of objects may then be transferred to a subsequent destination for further use or processing.
