Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for collecting and feeding metal elongated elements, such as metal profiles and rods for reinforced concrete, are bulky, expensive, and inefficient, particularly when dealing with flexible and intertwined elements, and struggle to quickly switch between different types of bars due to the complexity and rigidity of the systems.
Innovation Solution
A method and apparatus featuring a fixed structure with a central gripping member that collects metal elongated elements through a lowering and lifting motion, combined with a transfer assembly for orderly transfer to a feeding path, allowing for efficient selection, separation, and counting of elements, and enabling easy handling of various diameters and lengths without the need for extensive reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional conveyor chains with oscillatory motion are used to untangle metal bars, then the elements can be separated from bundles, but the apparatus becomes bulky, expensive, and complex
Solution Approach 1:
The patent extracts the gripping function from complex conveyor chains and concentrates it in a single magnetic gripping member. This member is lowered into the bundle to grasp bars at their mid-sections, then lifted to extract them. This eliminates the need for bulky oscillatory conveyor chains while maintaining effective separation of intertwined bars.
Solution Approach 2:
The patent replaces the mechanical oscillatory motion system with a magnetic field-based gripping system. The magnetic gripping member attracts and holds metal bars through magnetic force, eliminating the need for complex mechanical chains and oscillatory mechanisms. This substitution significantly reduces apparatus complexity while maintaining reliability in untangling.
2Reliability
If conventional oscillatory conveyor chains are used to support and untangle elements, then separation can be achieved, but the apparatus becomes expensive and bulky
Solution Approach 1:
The patent extracts the essential function of support and separation from heavy conveyor chains, concentrating it in a lightweight magnetic gripping member that is lowered and lifted to extract bars from the bundle. This eliminates the need for heavy stationary support structures while maintaining separation reliability.
Solution Approach 2:
The patent substitutes heavy mechanical conveyor chains with a magnetic field-based system. The magnetic gripping member provides both support and separation functions through magnetic attraction, eliminating the need for heavy mechanical structures. This significantly reduces apparatus weight while maintaining reliable separation of metal bars.
3Productivity
If fixed apparatuses with gripping means are used to collect bars from storage compartments, then productivity is improved, but the apparatus cannot quickly switch between different types of bars
Solution Approach 1:
The patent employs a dynamic gripping system where the magnetic gripping member can be lowered and lifted to adapt to different bar configurations. The system can collect bars from various positions in the bundle and adjust to different bar types (different diameters and lengths) without requiring physical reconfiguration of fixed components. This maintains high productivity while enabling quick switching between bar types.
Solution Approach 2:
The magnetic gripping member serves multiple functions: it can grasp bars at different positions, adapt to different bar diameters and lengths, and work with various bundle configurations. This universal gripping capability allows the apparatus to maintain high productivity while quickly switching between different types of bars without requiring reconfiguration.
4Quantity of substance
If drawing means are used to extract bars from intertwined bundles, then bars can be removed, but the drawing effort is considerable and bars advance by unequal quantities
Solution Approach 1:
The patent extracts bars from the bundle by lowering the magnetic gripping member into the bundle to grasp bars at their mid-sections, then lifting it to pull the bars out. This direct extraction method eliminates the need for drawing means that pull bars through the entire bundle length, significantly reducing the drawing effort required while maintaining uniform extraction of multiple bars.
Solution Approach 2:
The magnetic gripping member acts as an intermediary between the apparatus and the bars. It grasps multiple bars simultaneously at their mid-sections and lifts them together, ensuring uniform advancement of all extracted bars. This intermediary approach eliminates the unequal advancement problems associated with direct drawing methods.
