Oval Jaw Binding Apparatus for Reinforcement Bars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binding apparatuses for reinforcement bars in concrete constructions require excessive wire due to circular jaws that do not match the oval shape of the objects, leading to inefficient wire usage and difficulty in achieving a satisfactory binding force.
Innovation Solution
A binding apparatus with a wire path that guides the wire around objects using a rotatable binding head and inner tool member, allowing for axial movement and concurrent rotation to twist the wire, reducing wire usage and increasing binding force, while also incorporating sensors and a motorized wire supply for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If circular jaws are used to guide the wire, then the wire can be easily guided in a loop, but excessive wire is consumed due to mismatch with the oval shape of objects
Solution Approach 1:
The binding apparatus employs jaws with an oval cross-sectional shape that matches the oval shape of the objects to be bound, replacing the conventional circular jaws. This asymmetric design adaptation reduces wire consumption by eliminating the excessive material required to accommodate the shape mismatch between circular jaws and oval objects.
2Ease of operation
If twisting means grip the wire loop without previous tightening, then the wire loop can be twisted easily, but satisfactory binding force is difficult to achieve
Solution Approach 1:
The binding apparatus performs preliminary tightening of the wire loop around the objects before the twisting operation. This sequence ensures that the wire is properly tensioned and positioned, creating a solid foundation that enables the subsequent twisting to achieve satisfactory binding force and secure the objects effectively.
3Manufacturing precision
If multiple motors are used for feeding, twisting and sliding, then precise control of wire feeding and twisting is achieved, but device complexity and weight increase
Solution Approach 1:
The binding apparatus combines multiple functions (wire feeding, twisting, and sliding) into a single integrated motor system. This merging of functions reduces the number of separate motors and components, thereby simplifying the device structure and reducing weight while maintaining precise control through coordinated operation of the unified system.

Function Achieved in This Case
The apparatus achieves a reduced wire consumption and enhanced binding force with a simpler, lighter design, using sensors and a motorized system to ensure proper wire tension and length management, suitable for various objects including reinforcement bars and other applications.
Implementation Method 1
the inner tool member being connected to a rotatable spindle such that rotation of the spindle causes the inner tool member to move, axially relative to the binding head
Implementation Method 2
the binding head being locked for rotation in a direction opposite the first direction, whereby further rotation of the spindle causes concurrent rotation of the inner tool member and the binding head in a first direction relative to the wire path
Implementation Method 3
The concurrent movement of the inner tool member and the binding head in the first direction relative to the wire path, causes the free ends of a wire piece to be twisted
