US Patent 11999563 Automated warehouse and conveyance device

An automated warehouse includes a stacker crane, a switch, and a transfer controller. The stacker crane includes a traveling vehicle that travels in a first direction, a hoist carriage provided to the traveling vehicle, first and second transfer devices provided to the hoist carriage, and a lateral conveyor to move the first transfer device laterally on the hoist carriage. The switch switches between a first state that enables the lateral movement of the first transfer device and a second state that disables the same. When the switch selects the second state, the transfer controller moves the first and second transfer devices to positions corresponding to first and second shelves without moving the first transfer device laterally.
