The invention discloses an intelligent storage and conveying system for aluminum alloy round cast ingots. The system comprises an automatic stacking device, a temporary storage station, intelligent overhead travelling cranes and a cross-zone transfer trolley. The automatic stacking device is used for stacking the aluminum alloy round cast ingots, conveying the stacked aluminum alloy round cast ingots to a buffer station and transmitting a first control signal. The temporary storage station is used for temporarily storing the stacked aluminum alloy round cast ingots. The intelligent overhead travelling cranes are connected with the automatic stacking device and used for moving to the temporary storage station according to the first control signal, conveying the aluminum alloy round cast ingots stacked on the temporary storage station to a storage zone and transmitting a second control signal. The cross-zone transfer trolley is connected with the intelligent overhead travelling cranes and used for moving to the storage zone according to the second control signal to be loaded with the stacked aluminum alloy round cast ingots. The intelligent storage and conveying system has the advantages of intelligentization, automation and unmanned operation; work efficiency is improved; and the work intensity is lowered.
