Automatic sorting method and system for storage robot

Abstract

The invention discloses an automatic sorting method and system for a storage robot. The method includes the following steps that S1, orders are manually sent to the robot by holding the PDA in hands;S2, the storage robot moves to different order picking stations for order sorting in sequence according to distributed picking list information; S3, a sorter picks orders according to the picking listinformation pushed onto the hand-held terminal PDA by a robot system; S4, after the storage robot completes all goods sorting operations on a picking list, goods on the picking list are delivered toa sowing wall station together; S5, the goods on the storage robot arriving at the sowing wall station are taken down manually, and then the storage robot is released; S6, the picking list is scanned,and the goods taken down in the S5 are correspondingly sown according to the scanned picking list information; and S7, the goods sown in the S6 are rechecked, packaged and weighed and then are delivered out of storage. By adoption of the method, the robot sorting mode with manual work participating in sorting can be achieved, when the robot system breaks down, the mode can be directly switched into a manual sorting mode, and manual work can replace the robot to complete sorting delivery tasks thoroughly.

Description

Technical field [0001] The invention relates to the technical field of warehousing and logistics, in particular to an automatic sorting method and a sorting system for a warehouse robot. Background technique [0002] Existing logistics and warehousing robot (AGV) sorting technology all use shelf-to-person technical solutions to complete the automatic sorting of goods. The storage robot (AGV) transports the shelves where the goods to be sorted are directly from the storage area to the sorting station, and manually sorts the goods to be sorted. After picking, the storage robot puts the shelves back into the storage area. Such multiple products of an order need to be sent to the sorting workstation through the storage robot to multiple shelves containing the order products, and manual picking completes the sorting of multiple products in an order. [0003] In all business processes involving sorting, employees do not need to go inside the warehouse storage area, but just wait at the...

AI Technical Summary

Problems solved by technology

[0005] 1. The efficiency of replenishment is low. The goods are replenished according to a single piece. Robots are required to move the shelves where the goods are located to the replenishment workstations. The hit rate of replenishment for a single shelf is low;

[0006] 2. The sorting hit rate of a single shelf is low, and each mobile shelf can provide fewer commodities that need to be picked;

[0007] 3. The sorting efficiency is low, because the goods to be picked for each order are placed on different shelves, and the storage robot needs to carry multiple shelves to and from the sorting workstation, and the hit rate of the picked goods contained in each shelf is low, which in turn causes storage problems. There are too many repetitive paths for robots to carry shelves;

[0008] 4. The energy efficiency of the storage robot is low, because the storage robot for the goods required by an order may need to carry multiple mobile shelves to the sorting workbench. After the sorting is completed, the shelves need to be put back into the storage area, and the reciprocating path of the storage robot is too long ;

[0009] 5. When the system fails, it is difficult to replace it manually. When the storage robot system fails, it is impossible to find the goods manually, because the layout of all mobile shelves is a dynamic layout, and there is no fixed parking position for the mobile shelves;

[0010] 6. When the system fails, the traceability is low, and the system error leads to the wrong sorting of the goods. Because all the shelves in the storage area are dynamically arranged and the goods are not fixed, it is difficult to find the goods that need to be replaced and restored. Commodity location
