The current palletizing methods for egg shipping containers vary by container sizes, pallet sizes, and stacking methods among different customers. These inconsistent conditions restrict the construction of automated systems, so the current palletizing way still depends on labors. Workers are prone to occupational injuries during long-term and heavy-load actions. In this project a conveyor connected all of the egg packaging lines throughout the whole factory to transport the egg cartons to the boxing zone. A boxing robot loads the cartons into shipping containers, then the containers are moved the pelletizing zone. A RFID reader recognize the RFID tag on the containers and a palletizing robot stacks them to the designated pallet positions according to the products’ corresponding stacking method.
