After the sorting bin passes through the code reader of each storage logical area, the code reader uploads logical area information of the storage logical areas, and whether other storage logical areas need to generate sorting tasks in the current segmented logical area group is judged based on the logical area information. And after the logical area picking task A is finished, generating a logical area picking task B of the storage logical area B, and sending the logical area picking task B to a picking bin which is transferred from the storage logical area A.
When a picking bin diverted from storage logical area a is delivered to storage logical area B, a picker in storage logical area B scans the picking bin diverted from storage logical area a for a logical area picking order B and uses the bin for item picking. If the bin is full, a new pick bin is assigned using an unpacking function to sort items into the new pick bin. After the picking personnel finishes picking, the picking bins (which can be one or more) are placed at the wire throwing port B for wire throwing, and the delivery destination point of the picking bins is a section port C.
And after the logical area picking task B is completed, generating a logical area picking task C of the storage logical area C, and sending the logical area picking task C to a picking bin which is circulated from the storage logical area B. When the picking bins that have flowed from storage logical zone B are transported to storage logical zone C, the pickers in storage logical zone C scan the bin leader that has flowed from storage logical zone B for a logical zone picking order C and use the picking bins for picking. When the picking is complete, the merge is complete, and all of the pick bins corresponding to the completed logical zone picking order A, B, C are delivered to the merge zone.
In one embodiment, multiple segmented logical groups may be generated for the merge voucher, e.g., one of the multiple segmented logical groups includes pick logical zones that are warehouse logical zone a, warehouse logical zone B, and warehouse logical zone C. Performing segmentation confluence on each segmentation logical area group, judging that all article picking devices corresponding to all the area group picking tasks are conveyed to the confluence area after all the logical area picking tasks corresponding to one segmentation logical area group are finished, and if so, conveying all the article picking devices to a rechecking cache way in a rechecking area for rechecking the delivered articles conveyed by all the article picking devices; if not, continuing to wait until all item picking devices corresponding to all group picking orders are delivered to the merge area. During the picking process, if the current picking bin can not meet the current logical zone picking task, the picking personnel can distribute other picking bins for carrying the articles by using a unpacking mode.
