Binding Machine Wire Path Stabilization via Local Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional binding machines experience issues with wire looseness and buckling due to lack of means to prevent deviation from the reel, leading to instability and increased machine size, especially when using small-diameter flexible wires.
Innovation Solution
A binding machine with a feeding unit that includes first and second restriction units to control the wire path, ensuring it remains aligned and preventing deviation, combined with a curl guide design that offsets the virtual plane of the wire's arc formation to stabilize the wire path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wire is forced to be pulled back at the feeding unit, then the wire is fed out and pulled back to reduce the amount of wire used per binding, but looseness of the wire occurs between the feeding unit and the reel inside the housing unit
Solution Approach 1:
A guide member is introduced as an intermediary component between the feeding unit and the reel. This guide member restricts the wire from deviating from its entering route, thereby preventing looseness and maintaining stable wire alignment during the feeding and pullback operations that enable multiple binding times per reel.
2Ease of operation
If a curve is formed on the wire loosened inside the housing unit, then the wire is curled to form a loop for binding, but the deformation resistance of the wire is lowered and the wire buckles easily due to the force of the feeding unit
Solution Approach 1:
The guide member performs a preliminary action by restricting the wire from deviating before the wire reaches the curling position. By maintaining proper wire alignment and tension in advance, the guide member prevents the wire from becoming loosened and buckling when curvature is subsequently applied during the binding operation.
3Stability of the object's composition
If the wire is restricted from deviating using a guide member, then wire alignment is stabilized and buckling is prevented, but the housing unit size increases to accommodate the guide member
Solution Approach 1:
Instead of providing comprehensive restrictions throughout the entire housing unit, the guide member is positioned at the specific local area where wire deviation occurs - between the feeding unit and the reel. This localized approach provides necessary wire path stability without requiring the housing unit to be enlarged throughout its entire structure.

AI summary
The wire fed or pulled back from the reel by the feeding unit can be properly restricted. The invention relates to a binding machine (2) having a feeding unit (16) for feeding out a wire (3) from a reel (12) provided in a housing unit (11). With respect to the entering route (81) of the wire (3) when the wire (3) drawn out from the reel (12) by the feeding unit (16) is guided to the feeding unit (83), the first restriction unit (83) that restricts the drawing portion (3a) of the wire (3) disposed between the reel (12) and the feeding unit (16) from being deviating from the entering route (81) is provided inside the housing unit (11).
