Wire Feeding Member Alignment in Rebar Binding Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reinforcing bar binding machines experience feeding troubles due to uneven wear of the groove portions on the feeding members, leading to inconsistent wire feeding.
Innovation Solution
A binding machine with a pair of feeding members that rotate about a shaft, featuring a position regulation mechanism to maintain axial alignment, ensuring the wires are consistently sandwiched and fed without uneven wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the feeding members are made movable toward and away from each other to mount wires, then the ease of operation is improved, but the axial relative positions may be displaced causing uneven wear
Solution Approach 1:
The position regulation part is configured to regulate axial relative positions of the feeding members before wire feeding operation. This preliminary positioning action ensures that the feeding members are properly aligned prior to wire mounting and feeding, preventing uneven wear and maintaining reliable wire feeding throughout operation.
2Productivity
If the groove portions on feeding members are used to sandwich and feed wires, then the productivity is improved, but the groove portions become unevenly worn leading to feeding troubles
Solution Approach 1:
The position regulation part provides continuous feedback control of the axial relative positions of the feeding members. By monitoring and adjusting the positions to maintain proper alignment, the system compensates for wear and positional drift, ensuring consistent wire feeding through the groove portions throughout the operational life of the feeding members.

AI summary
A binding machine includes a wire feeding unit configured to feed a wire to be wound on an object to be bound, a binding unit configured to twist the wire wound on the object to be bound, a curl guide configured to curl the wire being fed by the wire feeding unit, and an inductive guide configured to guide the wire curled by the curl guide toward the binding unit. The wire feeding unit includes a pair of feeding members facing each other with a feeding path of the wire being interposed therebetween, each of the feeding members configured to rotate about a shaft as a support point extending in a direction intersecting with the feeding path of the wire, and a position regulation part configured to regulate axial relative positions of the pair of feeding members.
