Curl Guide Wire Alignment for Large-Rebar Binding Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binding machines face issues with misalignment of wires due to one wire moving towards another in the curl guide, leading to variations in landing position 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 a suppression part to align wires in contact with each other along the axial direction of the annular feeding path, using first, second, and third wire guides to regulate positions and prevent one wire from moving towards another, stabilizing the wire posture and ensuring proper alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the diameter of the annular feeding path is increased to handle larger diameter reinforcing bars, then the binding machine can accommodate larger objects, but the variation of landing position on the induction guide increases, causing wires to potentially fail to enter the induction guide
Solution Approach 1:
The patent introduces a curl guide as an intermediary component between the annular feeding path and the induction guide. The curl guide includes suppression parts that actively manage wire positions during the transition, preventing wires from moving toward each other and ensuring they land accurately on the induction guide even when the annular feeding path diameter is large. This intermediary structure resolves the contradiction by decoupling the size adaptation from the precision requirement.
2Reliability
If the induction guide is enlarged to ensure wires enter the induction guide, then the reliability of wire feeding is improved, but the binding machine increases in size and weight, deteriorating operability
Solution Approach 1:
The patent applies preliminary action by using the curl guide to pre-align and stabilize wire positions before they reach the induction guide. The suppression parts in the curl guide proactively prevent wire displacement toward each other, ensuring wires are already properly positioned when they approach the induction guide. This eliminates the need to enlarge the induction guide, maintaining both reliability and ease of operation.
3Adaptability or versatility
If one wire moves toward another wire in the curl guide, then the wires may become misaligned, but this variation in posture causes landing position variation and potential failure to enter the induction guide
Solution Approach 1:
The patent implements preliminary anti-action by incorporating suppression parts in the curl guide that actively counteract the tendency of wires to move toward each other. These suppression parts apply restraining forces or geometric constraints that prevent wire crossover or misalignment before the wires reach the induction guide. This preliminary counter-action ensures precise landing positions are maintained even though the system remains flexible enough to handle various wire configurations.

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.
