3D Unloading Shelf Layout for Direct Container Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unloading systems fail to efficiently unload goods into predetermined containers on shelves, leading to suboptimal space utilization and increased damage due to impact forces during unloading.
Innovation Solution
A three-dimensional unloading system utilizing self-navigation carts, a parcel identification device, positioning device, conveying device, and unloading device, which allows precise unloading into containers on movable shelves, reducing impact forces and improving space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If goods are unloaded at a predetermined outlet and then packaged at the same outlet, then the unloading process is simple, but space utilization is suboptimal and requires multiple handling steps
Solution Approach 1:
The patent introduces movable shelves that can be transported to packaging places, adding a spatial dimension to the unloading system. Instead of fixed outlets, goods are unloaded into containers on shelves that move to where packaging occurs, transforming the static unloading architecture into a dynamic multi-dimensional system that improves space utilization without complicating the unloading process
2Ease of operation
If shelves are transported to packaging places, then all goods can be conveniently transported, but the system complexity increases
Solution Approach 1:
The movable shelves serve multiple functions: they act as storage containers during unloading, serve as transport carriers to packaging locations, and function as temporary holding stations. This multi-functionality consolidates what would otherwise require separate systems (unloading station, transport mechanism, packaging station) into a single versatile platform, improving operational convenience without proportionally increasing system complexity
Solution Approach 2:
The shelves are designed to be self-propelled or automatically transported to packaging places, reducing the need for additional manual handling or complex external transport mechanisms. The system serves itself by having the storage containers automatically move to where they are needed, simplifying the overall system architecture while maintaining operational flexibility
3Productivity
If goods are unloaded directly into containers on movable shelves, then space utilization improves, but impact forces during unloading may increase
Solution Approach 1:
The system incorporates cushioning mechanisms in the containers and during the unloading process to mitigate impact forces before goods make contact. By preparing cushioning elements in advance and positioning them correctly, the system can directly unload into movable containers while protecting goods from damage, reconciling the benefits of direct unloading with the need for impact protection

AI summary
The present invention provides a three-dimensional unloading system capable of unloading goods into a container and a control method of the three-dimensional unloading system. The system comprises: sorting platforms; self-navigation carts; parcel identification devices; and positioning devices. The system further comprises more than one shelf consisting of a plurality of containers capable of storing goods, the shelf mounted close to an unloading outlet; a conveying device, on which a conveying frame is fixed; an unloading device, fixed on the conveying frame, the unloading device being capable of moving to the unloading outlet under the driving of the conveying device to receive the goods unloaded from the self-navigation cart, then moving to close to a predetermined container, and unloading the goods therein; and a server connected to a controller of the self-navigation cart, to the parcel identification device, and to the controllers of the conveying device and unloading device.
