PURPOSE: To reduce the operating time and to save the energy by providing a constitution to increase the floor area efficiency of a checkered dense accumulation automatic warehouse of pallet cargoes or a parking lot up to the maximum value in each scope, and a dense accumulation method to carry out the instant carrying out corresponding to the necessary carrying out date and time of each pallet cargo.
CONSTITUTION: At the lower parts of the longitudinal and the lateral center lines 15 and 16 of the pallets 13 checkered into longitudinal 12 lines and the lateral 10 lines, the longitudinal running and the lateral running individual conveyers or transfer devices making the longitudinal and the lateral checker intervals as the transfer units are provided, and they are moved vertically or drawing-transferred in the direction of necessary measure interval 14 individually. While a pallet cargo A on a carrying-in device 11 is alloted and transferred to the B measure between the reference pallets in an integrated carrying out time order alignment pallets, corresponding to a necessary carrying out time, an A' pallet in the carrying out order is transferred to the reference B' measure of a carrying out equipment 12. And the measure replacement transfer in the figure order measure is carried out respectively, and by composing the system to carry out the integrating operation by only one vacant checker in all the floor measures, the dense accumulation is carried out.
