Cache conveying equipment and method based on code unstacking

The invention relates to a temporary storage conveying device and method based on stacking and unstacking, which can keep a finished product conveying line and an assembly line in front of the finished product conveying line continuously working under the condition that a container is filled with finished product material bags to execute a container alternation process or a loading machine conveying line fails. The stacking operation is carried out by controlling the cooperation among the steering node, the buffer line and the stacker crane, and the stacker crane can be controlled to carry out unstacking operation when encasement operation needs to be continued, so that the finished product material bags are returned and conveyed to the car loader conveying line, and therefore, the whole assembly line can be in a continuous operation state; the operation efficiency is improved; and the production cost is saved. 本发明涉及一种基于码拆垛的缓存输送设备及方法，能够在集装箱装满成品物料袋执行轮换集装箱流程或是装车机输送线故障的情况下，能够保持成品输送线及在其之前的流水线继续作业，并通过控制转向节点、缓存线和码垛
