Rebar Binding Wire Alignment for Lower Clamping Plate Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reinforcing bar binding machines face inefficiencies in aligning and engaging wires, leading to increased load on clamping plates and decreased operation efficiency due to parallel wire alignment issues.
Innovation Solution
A binding machine with a wire feeding unit, a binding unit featuring openable/closable engaging members, and a control unit that regulates the alignment of two wires to be engaged, allowing for parallel alignment in a direction intersecting with the opening/closing direction of the engaging members, reducing the load on the clamping plates and improving operation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If two wires are aligned in parallel in the opening/closing direction of the clamping plates, then the binding force between reinforcing bars is improved, but the load applied to the clamping plates increases excessively
Solution Approach 1:
The patent changes the alignment direction of the two wires from the opening/closing direction (vertical dimension) to the horizontal direction perpendicular to the opening/closing direction. This dimensional change allows the wires to be engaged side-by-side rather than stacked, distributing the load across a wider area and reducing the force concentration on the clamping plates while maintaining effective binding.
2Strength
If two wires are aligned in parallel in the opening/closing direction of the clamping plates, then the binding force between reinforcing bars is improved, but the clamping plates cannot be closed to a predetermined position
Solution Approach 1:
By reorienting the wire alignment from the opening/closing direction to the horizontal direction, the patent eliminates the interference between wire stacking and clamping plate closure. The wires are now engaged side-by-side in the horizontal plane, allowing the clamping plates to close fully to the predetermined position without obstruction, thereby restoring operational accuracy.
3Strength
If two wires are aligned in parallel in the opening/closing direction of the clamping plates, then the binding force between reinforcing bars is improved, but the operation efficiency deteriorates due to stopping the binding operation
Solution Approach 1:
The patent's reorientation of wire alignment eliminates the need to stop the binding operation to detect or correct wire misalignment. By designing the engagement mechanism to naturally guide wires into the correct horizontal alignment, the system maintains continuous operation flow, preventing efficiency losses while still achieving the enhanced binding force from two-wire engagement.

AI summary
A binding machine includes a wire feeding unit configured to feed two wires to be wound on an object to be bound, a wire guide configured to align the two wires in parallel, a binding unit having an engaging member in which the wires are to be engaged, and the binding unit configured to twist the wires which are wound on the object to be bound and which are engaged in the engaging member, a curl guide configured to curl the wires being fed by the wire feeding unit into a loop shape, an inductive guide configured to guide the wires curled by the curl guide toward the binding unit, and a parallel alignment regulation part configured to guide an alignment direction of the two wires to be engaged with the engaging member in a radial direction of the loop.
