Spinning Station Wire Tension Control for Rear Rod Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing reinforcement meshes require substantial space and are prone to wire breakage during the loading of reinforcement rods, especially when producing large-scale meshes.
Innovation Solution
A spinning station apparatus with a spinner head unit, upper and lower wire coils, a support, feeding means, and a guide wheel system that allows reinforcement rods to be introduced from behind, reducing the risk of wire breakage by controlling the tension of the wire during loading through a cylinder-operated guide wheel mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If reinforcement rods are supplied from the side of the apparatus, then the rods can be introduced between the spinner head and wire meeting point, but the apparatus requires a considerable amount of space
Solution Approach 1:
The patent inverts the conventional approach by supplying reinforcement rods from the rear end of the apparatus instead of from the side. The feeding means introduces rods from behind the spinner head, reversing the traditional feed direction and enabling compact lateral arrangement of wire coils while maintaining rod introduction capability
2Area of stationary object
If reinforcement rods are supplied from the rear end of the apparatus, then the space requirement is reduced, but the wire has a tendency to break when a reinforcement rod is forced below it during the loading operation
Solution Approach 1:
The patent applies dynamics by making the first wire movable between tightened and loosened states. The wire tensioning device dynamically adjusts the first wire's tension based on operational phase: loosened during rod loading to prevent breakage, and tightened during spinning to ensure proper mesh formation
Solution Approach 2:
The patent implements preliminary action by loosening the first wire before the reinforcement rod is forced below it during loading. This preemptive relaxation of wire tension prevents the wire from breaking when the rod passes through, addressing the reliability issue before it occurs
3Reliability
If the first wire is continuously tightened to prevent breakage, then wire strength is maintained, but the rod cannot be easily introduced from behind the spinner head
Solution Approach 1:
The system dynamically adjusts wire tension based on operational phase. During rod loading from behind, the first wire is loosened to facilitate easy introduction. During the spinning operation, the wire is tightened to maintain strength and prevent breakage, thus resolving the contradiction between ease of operation and wire strength
