Strip-Winding Roller Inclination Control for Tire Gap Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In strip-winding processes for tires, the constant roller inclination angle leads to gaps between strip portions on inclined parts of the wound body, causing quality deterioration due to varying circumferential lengths and diameters.
Innovation Solution
A strip-winding method and apparatus that dynamically adjusts the roller inclination angle based on the position around the wound body, particularly increasing it for inclined parts to match the gap value at the maximum diameter position, ensuring consistent strip placement and preventing quality deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a constant roller inclination angle is used during strip winding, then the winding process is simple and stable, but gaps appear between strip portions on inclined parts of the wound body, causing quality deterioration
Solution Approach 1:
The roller inclination angle is changed from a constant static value to a dynamic variable that adjusts according to the winding position. The control system dynamically modifies the roller inclination angle based on real-time position detection, enabling the system to adapt to different sections of the wound body (constant diameter vs. inclined parts) and maintain consistent gap values throughout the winding process.
Solution Approach 2:
The roller inclination angle parameter is modified based on the winding position. The control system changes this parameter from a fixed constant to a variable that increases on inclined parts of the wound body, compensating for the varying circumferential lengths and preventing gap formation between adjacent strip portions.
2Manufacturing precision
If the roller inclination angle is increased for inclined parts, then consistent gap values are achieved, but the control system becomes more complex
Solution Approach 1:
The control system incorporates feedback from position detection to automatically adjust the roller inclination angle. Detectors monitor the winding position and provide feedback signals to the control system, which then adjusts the roller inclination angle accordingly, creating a closed-loop control system that maintains precision without requiring manual intervention.
Solution Approach 2:
The control system acts as an intermediary between the position detection and the roller inclination mechanism. It receives position information from detectors, processes this information, and generates appropriate control signals to adjust the roller inclination angle, mediating between the detection system and the execution mechanism.
3Ease of operation
If a constant roller inclination angle is used, then the apparatus operation is simple, but the circumferential lengths of strips do not align with varying diameters of the wound body
Solution Approach 1:
The roller inclination angle transitions from a static constant value to a dynamic variable that automatically adjusts with winding position. This dynamic adjustment ensures that the circumferential length of each strip portion aligns with the local diameter of the wound body, maintaining manufacturing precision while preserving operational simplicity through automation.
Solution Approach 2:
The roller inclination angle parameter is continuously adjusted based on the winding position and local diameter characteristics. This parameter change compensates for the varying circumferential lengths on inclined parts, ensuring proper alignment and consistent gap values without requiring complex manual operations.

AI summary
The strip-winding method, includes: a first step of supplying a strip to a wound body including an inclined part; and a second step of moving a winding roller along an outer circumferential surface of the wound body within one plane, the winding roller being capable of pressing the strip on the wound body, and of winding the strip on the outer circumferential surface of the wound body. In the second step, the roller inclination angle of the rotational axis line of the winding roller with respect to the one plane is changed, and the roller inclination angle at the time the strip is wound around the inclined part is set to be greater than the roller inclination angle at the time the strip is wound around a maximum diameter position of the wound body.
