Rebar Binding Machine Magazine Partition Against Wire Entanglement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reinforcing bar binding machines face issues with wire entanglement due to displacement of the wire during reverse and forward feeding operations, leading to entanglement with the wire wound on the reel.
Innovation Solution
A binding machine with a magazine featuring a separation part between the reel accommodation position and the wire feeding path to prevent wire displacement and entanglement, ensuring the wire pulled out from the reel does not interfere with the wire already wound on the reel during forward feeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wire is fed in reverse direction to wind on the to-be-bound object, then the wire can be wound properly, but the wire displaced toward the reel causes entanglement with the wire wound on the reel
Solution Approach 1:
The magazine is divided into two distinct regions by a partition: a reel accommodation space and a wire feeding path. This segmentation prevents the wire pulled from the reel from contacting the reel during reverse feeding operations, eliminating entanglement while maintaining proper wire winding function.
Solution Approach 2:
A partition wall acts as an intermediary structure between the reel accommodation space and the wire feeding path. This partition serves as a physical barrier that guides the wire along a controlled path, preventing direct contact between the pulled wire and the reel while still allowing the wire to be fed smoothly.
2Volume of moving object
If the wire feeding path is positioned close to the reel for compact design, then the device size is reduced, but wire entanglement occurs during operation
Solution Approach 1:
The partition creates a three-dimensional separation within the magazine structure, dividing the internal space into distinct zones. This spatial arrangement in multiple dimensions allows compact overall design while maintaining functional separation between the reel accommodation area and wire feeding path, preventing entanglement.
3Object-generated harmful factors
If the wire feeding path is separated from the reel accommodation position, then wire entanglement is prevented, but the magazine structure becomes more complex
Solution Approach 1:
The magazine is segmented into two functional zones by a simple partition structure. This segmentation achieves wire entanglement prevention through straightforward spatial division rather than complex mechanisms, maintaining structural simplicity while effectively solving the entanglement problem.

AI summary
A binding machine including a magazine in which a reel having a wire wound thereon is accommodated, a wire feeding unit configured to feed the wire pulled out from the reel accommodated in the magazine, a curl forming unit configured to form a path along which the wire fed by the wire feeding unit is to be wound around an object, a cutting unit configured to cut the wire wound on the object, and a binding unit configured to twist the wire wound on the object and cut by the cutting unit. The magazine comprises, between an accommodation position of the reel and a feeding path of the wire, a partition configured to separate the accommodation position of the reel and the feeding path of the wire.
