Curl Guide Wire Suppression for Large-Rebar Binding Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binding machines face issues with misalignment of wires due to movement towards each other in the curl guide, leading to variations in landing positions and potential failure to enter the induction guide, especially when binding larger diameter reinforcing bars, which can result in increased machine size and weight.
Innovation Solution
A binding machine with a curl guide that includes first, second, and third wire guides to regulate wire positions, featuring a suppression part to prevent one wire from moving towards another, maintaining alignment and stability, allowing the machine to handle larger diameters without enlarging the induction guide.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the diameter of the annular feeding path is increased to bind larger diameter reinforcing bars, then the binding capability is improved, but the variation of landing position on the induction guide increases
Solution Approach 1:
The patent introduces a curl guide as an intermediary component between the wire feeding portion and the induction guide. The curl guide includes suppression parts that actively prevent wires from moving toward each other during the curling process, thereby stabilizing the landing position on the induction guide even when the annular feeding path diameter is increased for binding larger reinforcing bars.
2Reliability
If the induction guide is enlarged to ensure wires enter the induction guide, then the reliability of wire entry is improved, but the machine size and weight increase
Solution Approach 1:
The curl guide with suppression parts creates a self-aligning mechanism where the wires are automatically prevented from deviating toward each other during feeding. This self-regulating feature ensures reliable wire entry into the induction guide without requiring the induction guide itself to be enlarged, thereby avoiding the associated increase in machine size and weight.
3Adaptability or versatility
If one wire moves toward another wire in the curl guide, then the wire alignment is disrupted, but this leads to variation in landing position and potential failure to enter the induction guide
Solution Approach 1:
The suppression parts in the curl guide apply preliminary anti-action by preemptively preventing wires from moving toward each other during the curling process. This preventive measure is implemented before the wires can deviate from their proper alignment, ensuring that the landing position on the induction guide remains stable and that wire entry is successful.

AI summary
A binding machine includes a curl forming portion. The curl forming portion includes a curl guide configured to curl a plurality of wires. The curl guide includes a first wire guide configured to regulate positions of the wires directed toward a radially outer periphery side with respect to a radial direction of a annular feeding path, a second wire guide configured to regulate positions of the wires directed toward one axial side with respect to an axial direction of the annular feeding path, and a third wire guide configured to regulate positions of the wires directed toward the other axial side. The curl guide includes a suppression part configured to suppress one wire of the plurality of wires from moving in a direction toward another wire.
