Binding Machine Joint Strength Testing via Single Movable Clamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binding machines lack an efficient method for testing the strength of joints formed in loops of binding elements, such as wires or straps, which is crucial for ensuring secure binding and material integrity.
Innovation Solution
A binding machine equipped with a feeding and tensioning device, a gripping arrangement, and an electronic control system that forms a joint between binding element sections and subjects it to a tensile test by exerting a controlled force, ensuring the joint takes the entire tensile force and allowing for secure testing of the binding element's strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stationary clamping member and a moveable clamping member are used to grip the wire on opposite sides of the joint for tensile testing, then the joint strength can be tested, but the testing process becomes complex and time-consuming
Solution Approach 1:
The invention extracts the testing function from a complex dual-clamping mechanism and concentrates it into a single moveable clamping member. By removing the stationary clamping member and using only the moveable clamping member to grip the binding element at the leading end, the system achieves joint strength testing with reduced mechanical complexity while maintaining reliability.
Solution Approach 2:
The moveable clamping member serves multiple functions: it grips the binding element during the binding operation and subsequently serves as the sole clamping device for tensile testing. This multi-functionality eliminates the need for a separate stationary clamping member, simplifying the overall device structure while enabling complete joint strength assessment.
2Measurement precision
If the gripping arrangement keeps the first binding element section secured in fixed position by engagement with a part located between the joint and the leading end, then the joint takes up the entire tensile force for accurate testing, but the gripping arrangement must be precisely positioned
Solution Approach 1:
The invention uses a specific part of the binding element itself (located between the joint and the leading end) as an intermediary engagement point for the clamping member. This intermediary point serves as a reliable reference that naturally positions the clamping member at the correct location, ensuring accurate tensile force application without requiring complex external positioning mechanisms.

Implementation Method 1
an electronic control device configured to control the feeding and tensioning device to exert a tensile force on the binding element after the formation of said joint in order to subject the joint to a tensile test and thereby check the strength of the joint

AI summary
A binding machine including a feeding and tensioning device for feeding a binding element in the form of a wire or strap around a space, and a joining device for forming a joint between a first binding element section at the leading end of the binding element and a second binding element section at the trailing end of a piece of the binding element arranged in a loop in or around the space to thereby form a closed loop of this piece of the binding element. The feeding and tensioning device is configured to exert a tensile force on the binding element in order to subject the joint to a tensile test. During this test, a gripping arrangement is configured to keep the first binding element section secured in fixed position by engagement with a part of the first binding element section located between the joint and the leading end of the binding element.
