Compact Dynamic Buffer Shuttle for Packaging Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dynamic buffer machines for packaging are large and cumbersome, making them difficult to transport and install, and they lack flexibility to adapt to items of varying dimensions.
Innovation Solution
A compact dynamic buffer system featuring at least two movable shuttles on a closed circuit, capable of automatically changing the pitch of individual seats to accommodate items of different dimensions, and equipped with sensors and actuators to adjust packaging tension and configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional large buffers are used, then items can be adequately accumulated and prepared, but the machine becomes difficult to transport and install
Solution Approach 1:
The buffer is divided into multiple independent shuttles that can move individually along the conveyor circuit. Each shuttle acts as an independent storage unit, allowing the system to maintain adequate item accumulation capacity while reducing the overall machine footprint and improving transportability.
Solution Approach 2:
The shuttles are designed to be movable rather than fixed, allowing them to dynamically adjust their positions along the conveyor circuit. This dynamic configuration enables the buffer to adapt to different item quantities and packaging requirements while maintaining a compact form factor that is easier to transport and install.
2Adaptability or versatility
If fixed pitch conveyor belts are used, then the structure is simple, but the system lacks flexibility to handle items of varying dimensions
Solution Approach 1:
The conveyor system incorporates variable pitch mechanisms that allow the distance between conveyor elements to be dynamically adjusted. This enables the system to adapt to items of varying dimensions while maintaining a relatively simple overall structure through modular design.
Solution Approach 2:
The system changes the pitch parameter of the conveyor belt to match different item dimensions. By making the pitch variable rather than fixed, the system achieves flexibility in handling various item sizes without requiring completely different conveyor structures for each item type.
3Adaptability or versatility
If multiple independent shuttles are used, then item handling flexibility is improved, but the system becomes more complex and costly
Solution Approach 1:
Multiple shuttles are merged into a single integrated system that shares common control logic and infrastructure. The shuttles operate independently physically but are coordinated through a unified control mechanism, reducing overall system complexity and cost while maintaining item handling flexibility.
Solution Approach 2:
The shuttles are designed with universal capabilities to handle different item types and configurations. Each shuttle can perform multiple functions including loading, unloading, and temporary storage, reducing the need for specialized equipment and simplifying the overall system architecture.
