Bosch & Siemens Chuzhou Refrigerator Factory is specialized in the production of high-end refrigerators, with an annual output of 300,000 sets. This Phase I project is the demo project of Bosch and Siemens intelligent logistics strategy and the first project that is put into operation. Three AGVs of the Phase I project are in charge of the packaging material storage and material supply to the packaging line, including the exchange with the mechanical arm and the man-machine exchange. This project can save six porters every day, which greatly saves the labor cost. At present, the project has entered the phase II, covering other production lines and aiming at realizing unmanned handling in the whole plant by 2022.
