Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary hopper feeders face inefficiencies in conveying and separating elements with shafts, as misalignment and impurities lead to maintenance issues and reduced yields due to jamming and improper alignment.
Innovation Solution
The rotary hopper feeder features radially oriented conveyor cells with holes and a rolling surface for shafts to roll on, an inclined design, discharge slopes for misaligned elements, and a peripheral wall for positional alignment, along with a discharge baffle system to prevent jamming and facilitate ejection by gravity, ensuring efficient alignment and maintenance reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conveyor cells are used to convey elements with shafts, then elements can be conveyed and separated, but misaligned elements and impurities accumulate causing maintenance issues and reduced yields
Solution Approach 1:
The patent extracts impurities and misaligned elements from the conveyor system through discharge slopes and baffles that channel these contaminants out of the conveyor cells and through the rolling surface, preventing them from accumulating and causing maintenance issues while maintaining high yield
Solution Approach 2:
The rolling surface and discharge slopes are designed to automatically eject misaligned elements and impurities using gravity and the rotational motion of the conveyor cells themselves, without requiring external intervention or complex cleaning mechanisms, thus maintaining reliability and productivity
2Manufacturing precision
If discharge baffles are provided to eject misaligned elements, then positional alignment is improved, but elements may jam in the holes of the rotary feeder
Solution Approach 1:
The patent segments the discharge function into multiple components: discharge slopes on the conveyor cells, discharge baffles positioned strategically, and rolling surface features. This segmentation allows misaligned elements to be progressively ejected at different stages, reducing the likelihood of jamming while maintaining precision
Solution Approach 2:
Instead of trying to push misaligned elements out through forceful means that cause jamming, the patent inverts the approach by using gravity-assisted discharge slopes and carefully designed baffle geometries that allow elements to slide out smoothly, reducing harmful jamming effects while maintaining alignment precision
3Ease of operation
If the rotary feeder is inclined to enable rolling motion, then shafts can roll on the rolling surface, but elements may fall out of conveyor cells ahead of time
Solution Approach 1:
The patent introduces a peripheral wall as an intermediary structure between the inclined rotary feeder and the output. This wall acts as a mediator that prevents elements from falling out too early while still allowing the rolling motion to occur, thus maintaining both ease of operation and stable element positioning throughout the conveyance process
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the efficiency of conveying and separating elements by minimizing maintenance, preventing impurities from accumulating, and ensuring high yields through effective alignment and ejection of misaligned elements, resulting in longer maintenance intervals and improved system performance.
Implementation Method 1
a rolling surface is provided on which at least part of the shafts of said elements with shafts are supported and made to roll as they are conveyed
Implementation Method 2
This will facilitate the ejection at a discharge baffle of elements to be conveyed which have a head and whose shaft length is shorter than the height of the rotary feeder at the hole. This reliably allows the ejection of any misaligned elements, thus emptying conveyor cells for the reception of new elements
