Shelf unit, shelf, goods sorting system and goods sorting method

Abstract

The invention discloses a goods shelf unit, a goods shelf, a goods sorting system as well as a goods sorting method. The goods shelf unit comprises a hollow main supporting structure and a hollow tray bearing structure, wherein the front side of the main supporting structure is opened; the front side of the tray bearing structure is opened, and the tray bearing structure is supported on the main supporting structure, and comprises a tray bearing surface used for supporting a tray; the goods shelf unit is provided with a hollow region and a front side opening communicating with the hollow region; and the front side opening, the hollow region and the tray bearing structure are arranged in the manner that a robot bearing the tray can enter the hollow region from the front side opening and place the tray on the tray bearing surface in the hollow region, the robot without load can take down and bear the tray from the tray bearing surface in the hollow region, and the robot bearing the tray can drive away from the hollow region from the front side opening. According to the goods shelf unit disclosed by the invention, the effective loading rate of the robot can be improved.

Description

Technical field [0001] The invention relates to the technical field of storage, in particular to a shelf unit, a shelf, a goods sorting system and a goods sorting method. Background technique [0002] In the warehousing industry, Amazon's goods sorting system, which uses Kiva robots to sort goods, upgrades goods sorting from the traditional human-to-goods picking model to the goods-to-human picking model. [0003] The goods sorting system provides a new type of automated order fulfillment program. By using hundreds of mobile robots (Kiva robots), movable shelves, workstations and complex control software, the picking, packaging and conveying operations of the distribution center are completed. Its main equipment includes storage equipment and handling equipment (Kiva robot). The storage equipment of the cargo sorting system uses mobile plastic racks (Pods). According to the different storage properties, the storage devices in the goods sorting system are divided into two types: ...

AI Technical Summary

Problems solved by technology

[0007] 1. The robot must put an inventory shelf on top of it before moving the pallet. Without this process, the pallet cannot be moved

[0008] 2. In the process of operation, not only pallets but also inventory shelves need to be managed, and the management cost is relatively high

[0009] 3. If the whole pallet of goods is stored on the high shelf, special equipment must be used to move the whole pallet of goods to the Kiva robot after the pallet is removed from the shelf
