Rebar Binding Reel Layout for Stable Multi-Wire Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reinforcing bar binding machines face challenges in managing multiple wires, including abnormal wire deformation and curl differences, which complicate wire feeding paths and increase management costs, especially as reel size increases and winding amounts grow.
Innovation Solution
A binding device with a main body and traveling part that accommodates multiple reels, each with a single wire wound, and a path induction system to form a controlled wire feeding path, eliminating entanglement and curl differences by ensuring each wire is wound on a separate reel, thereby reducing manufacturing costs and improving yield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple wires are wound on one reel to increase winding capacity, then the amount of wire accommodated increases, but wire entanglement and curl differences occur
Solution Approach 1:
The invention divides the single reel into multiple separate reels, with each reel accommodating exactly one wire. This segmentation eliminates wire entanglement and curl differences between wires while still achieving high winding capacity through the use of multiple reels in parallel.
2Quantity of substance
If reel size is enlarged to increase winding amount, then wire capacity increases, but wire management complexity increases
Solution Approach 1:
Instead of using one large reel, the invention uses multiple smaller reels, each dedicated to a single wire. This segmentation simplifies wire management and feeding path control while collectively accommodating the required total amount of wire through parallel arrangement.
3Quantity of substance
If multiple wires are wound on one reel, then winding capacity increases, but manufacturing cost increases
Solution Approach 1:
The invention uses multiple simple, small reels instead of one complex, large reel. Each small reel is easier and cheaper to manufacture, and their combined capacity equals or exceeds that of the single large reel, thereby reducing overall manufacturing costs.

AI summary
A binding device includes a main body part and a traveling part configured to travel the main body part. The main body part includes a binding mechanism configured to feed a plurality of wires around a reinforcing bar, and to twist and bind the plurality of wires fed around the reinforcing bar, a binding mechanism moving part configured to move the binding mechanism between a binding position where binding of the reinforcing bar is performed and a retreat position away from the reinforcing bar, a reel accommodation part configured to accommodate a plurality of reels on each of which one wire is wound, and a path induction part configured to form a feeding path of wires pulled out from the plurality of reels accommodated in the reel accommodation part between the binding mechanism and the reel accommodation part.
