Autoloading Shingle Feeder with Segmented Belt and Separator Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional autoloading shingle feeders are ineffective in singulating delicate materials due to the high forces exerted in the friction nip, leading to unpredictable separation of bottom-most articles from the stack, resulting in overlapping and inaccessible surfaces for tasks like stamping or addressing.
Innovation Solution
An autoloading shingle feeder with a distinct loading and feeding belt system, featuring a carriage assembly with a separator plate that limits vertical movement and applies gradual separation forces, allowing for precise singulation of individual articles from a stack, using a housing with a base and guides to support the belts and a controller for independent belt movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional friction feeders use high forces in the friction nip to separate bottom-most articles, then separation force is improved, but delicate materials are damaged and separation becomes unpredictable
Solution Approach 1:
The patent divides the feeding system into distinct loading and feeding belts with separate functions. The loading belt presents articles to the friction nip while the feeding belt receives singulated articles, allowing the friction nip to operate at optimal force without directly handling delicate materials throughout the entire feeding process.
Solution Approach 2:
The patent introduces a carriage assembly with separator plates as an intermediary mechanism between the friction nip and the feeding process. This intermediary gradually limits vertical movement of articles and guides them onto the feeding belt, reducing the impact of high friction nip forces on delicate materials.
2Productivity
If traditional friction feeders apply high forces to achieve separation, then separation capability is improved, but material damage increases
Solution Approach 1:
The patent employs independently controlled loading and feeding belts that can move at different speeds and accelerations. This dynamic control allows the system to optimize separation capability during the friction nip phase while minimizing damage during the feeding phase by adjusting belt speeds to match delicate material requirements.
Solution Approach 2:
The carriage assembly acts as a mediator that gradually transitions articles from the high-force friction nip environment to the lower-force feeding belt, protecting delicate materials from sudden force transitions while maintaining separation capability.
3Device complexity
If traditional feeders use a single belt system, then device complexity is reduced, but feeding precision and singulation performance deteriorate
Solution Approach 1:
The patent segments the feeding system into distinct loading and feeding belts, each optimized for its specific function. This segmentation enables precise control over article presentation and reception, improving singulation precision despite the increased structural complexity.
Solution Approach 2:
The patent replaces the traditional single mechanical belt system with a more complex but controllable dual-belt system coupled with a carriage assembly, enabling precise mechanical control over the singulation and feeding process that outweighs the added structural complexity.
