Container Shuttle System for Automated Bin Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sorter systems face inefficiencies and operator safety issues due to the need for manual handling of heavy bins, which can lead to system shutdowns when bins are full, and existing automation solutions are often complex and large.
Innovation Solution
A sorter system incorporating a container shuttle system with a conveyor and shuttle unit that transports items and containers, allowing for automated movement of containers between loading and staging areas, minimizing operator handling of heavy containers and optimizing container allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual bin handling is used in conventional sorter systems, then operator flexibility is maintained, but operator safety deteriorates due to heavy lifting and system productivity deteriorates due to shutdowns when bins are full
Solution Approach 1:
The system enables self-service through automated container handling. The shuttle unit automatically transports containers between the conveyor and staging areas without human intervention. The system monitors container fill levels and triggers automatic replacement, eliminating the need for operators to manually handle heavy bins while maintaining continuous operation
Solution Approach 2:
The system performs preliminary actions by pre-positioning empty containers in staging areas before they are needed. The shuttle unit proactively transports empty containers to ready positions, so when a container becomes full, its replacement is already prepared and immediately available, preventing system shutdowns
2Reliability
If automated bin handling systems are implemented, then operator safety is improved, but device complexity increases and becomes overly large and complex
Solution Approach 1:
The automated system is segmented into modular functional units: a shuttle unit with tray, loading area, and staging area. Each component performs a specific function and can be independently maintained or replaced. This modular segmentation reduces overall system complexity compared to monolithic automated handling systems
Solution Approach 2:
The shuttle unit acts as an intermediary between the conveyor and staging areas, simplifying the automation architecture. Rather than complex direct coupling between multiple automated systems, the shuttle unit mediates container transfer, reducing overall system complexity while maintaining safety

AI summary
A sorter system includes a first conveyor for transporting items to designated containers, a second conveyor for transporting containers containing the items, and a shuttle unit. The shuttle unit may include a base defining a loading area proximate to the first conveyor and a staging area proximate to the second conveyor and a tray disposed on the base for receiving containers on a first section and a second section. The tray may be movable between a first position in which the first section is in the loading area and a second position in which the first section is in the staging area. The shuttle unit may further include a transport device for selectively moving a container on the first section of the tray from the staging area onto the second conveyor.
