Robot automatic sorting method and system based on simultaneous picking and sorting

Abstract

The invention discloses a robot automatic sorting method and system based on simultaneous picking and sorting. The robot automatic sorting method comprises the following steps that a robot is dispatched by manually operating a handheld terminal PDA; S2, the robot carries a goods shelf to leave for a sorting station to conduct sorting according to distributed dispatching information; S3, the robotarrives at the corresponding laneway sorting station to acquire a laneway order task until completing all commodity sorting work on a laneway order; S4, a trolley is pushed to the sorting station to conduct seeding and puts commodities into corresponding goods grids of the goods shelf of the robot to conduct seeding; S5, after completion of seeding, the robot is released; if there is uncompleted order tasks, the robot carries the good shelf to automatically leave for the next sorting station to repeat operations in the steps S3 and S4 until completing all the sorting order tasks. Through the robot automatic sorting method, manpower participates in sorting; sorting and seeding tasks are completed simultaneously at the sorting station; as sorting and seeding are completed at the sorting station simultaneously, the number of seeding personnel is reduced while the procedures are reduced, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of warehousing and logistics, in particular to a robot automatic sorting method based on sorting while sorting and a system thereof. Background technique [0002] In the existing logistics storage robot (AGV) sorting technology, the automatic sorting of goods is mainly completed by the technical scheme of shelf-to-person and vehicle-to-person. Shelf-to-person mode: the picking area is an unmanned area, only the AGV carries out the handling operation, and the shelf is always in a dynamic environment; the AGV directly transports the shelf where the target goods are located from the picking area to the sorting workstation, and the goods are manually sorted; the order is completed After picking for the first time, the robot puts the shelf back into the picking area; in this way, multiple items of an order are sent to the sorting workstation through the AGV, and multiple items are manually picked to complete an o...

AI Technical Summary

Problems solved by technology

[0004] 1. The sorting hit rate of a single shelf is low, and each mobile shelf can provide less goods to be picked;

[0005] 2. The sorting efficiency is low, because the goods that need to be picked for each order are placed on different shelves, and the 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

Causes the robot to carry the shelves to walk too many repeated paths;

[0006] 3. The energy efficiency of the robot is low, because the robot may need to carry multiple mobile shelves to the sorting table for the goods required by an order. After the sorting is completed, the shelves need to be put back into the storage area, and the path for the robot to reciprocate is long;

[0007] 4. The replenishment efficiency is low. Products are replenished on a single-item basis. Robots are required to move the shelves where the products are located to the replenishment workstations. The hit rate of replenishment for a single shelf is low;

[0008] 5. In the case of system failure, it is difficult to replace manually. When the robot system fails, it is impossible to find goods manually, because the layout of all mobile shelves is dynamically arranged, and there is no fixed parking position for mobile shelves;

[0009] 6. In case of system failure, the traceability is low, and the system error causes the sorting error of the goods. Due to the dynamic layout of all the shelves in the sorting area, the position of the goods is not fixed, so it is difficult to find the position of the goods that need to be replaced and restored.

[0012] 2. The sowing post increases the labor cost. After the picker completes the picking according to the picking list information pushed by the robot system to the handheld terminal PDA, the sowing staff needs to perform secondary sorting at the sowing wall. Increasing shortage and rising labor costs
