the drive assemblies 130 of the two cargo lifts drive the corresponding cargo bed assemblies 120 and the change layer assemblies 140, respectively, to a first height;

the first driving parts 141 of the two layer changing assemblies 140 respectively drive the corresponding layer changing guide rails 142 to move forward along the first direction, so that the two layer changing guide rails 142 are in butt joint with the two shelf guide rails positioned at the original layer in a one-to-one correspondence manner;

It should be noted that, the shuttle 400 performs different tasks under the scheduling of the Warehouse Control System (WCS), and when the layer-changing lifts at two sides of the roadway perform different cargo conveying tasks respectively, the shuttle 400 reciprocates at the original layer thereof, so as to perform the task of picking and placing the cargo to the same layer but different storage positions of the shelf 300. When the shuttle 400 needs to be changed to another floor (the target floor) to perform the task, the Warehouse Control System (WCS) will send instructions to the shuttle 400 and the two corresponding floor-changing lifts, which change the shuttle 400 to the target floor of the goods shelf 300 according to the above method.

In some embodiments, the shuttle automation vertical warehouse further comprises a control cabinet comprising a PLC controller, a 24VDC power module, a reactor, a motor driver, and the like. The 24VDC power module mainly aims to provide control power or signal power for the whole control system, each sensor and the like. The PLC is mainly used for controlling the two layer-changing elevators and receiving and executing scheduling tasks of a Warehouse Control System (WCS). The motor driver uses a siemens S120 series driver to drive the driving motors 131 of the two sets of cargo lifts respectively. The reactor mainly eliminates the mutual interference and harmonic influence of the starting motor driver and the main power grid. In the embodiment of the present invention, the warehouse control system and the controllers are not limited to include specific control programs, and existing programs capable of achieving control purposes may be used as needed.
