Parallel warehouse-out type automatic warehousing system

The invention discloses a parallel ex-warehouse type automatic warehousing system which comprises a dense goods shelf subsystem, an automatic warehousing subsystem and an automatic ex-warehouse subsystem, the dense goods shelf subsystem comprises dense goods shelves, the dense goods shelves are divided into multiple columns, each column is divided into multiple layers, and each layer on each column is a goods lattice; the automatic warehousing subsystem comprises RGVs, RGV lifters and RGV rails, the RGVs are connected with the RGV lifters and reach the layer where the target position is located through the RGV lifters, the RGV rails are arranged on one sides of the dense goods shelves, the RGVs move on the RGV rails, the directions of the RGV rails are consistent with the directions of the dense goods shelves, and one ends of the RGV rails are connected to the positions of the RGV lifters; according to the warehouse-in and warehouse-out system, warehouse-in and warehouse-out operation can be carried out simul
