Solution Overview
Problem
Current systems lack the capability to automatically process both curved and flat separators and apexes of varying heights and shapes, necessitating separate systems for different tire types, which limits productivity and stability in core package production.
Innovation Solution
A device with a rotatably mounted plate featuring multiple processing stations, a height adjustment system, and a gripper drive system that can center and fix both flat and curved separators and bead cores, allowing for the production of core packages with apex heights up to 100 mm, including the use of base rings for precise alignment and centering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate systems are used for different tire types and apex heights, then manufacturing precision for specific configurations is maintained, but device complexity and productivity are reduced
Solution Approach 1:
The device employs a universal processing system that can handle multiple tire types and apex heights through adjustable base rings with different diameters and height adjustment mechanisms. This multi-functional design eliminates the need for separate systems while maintaining manufacturing precision through configurable processing stations.
Solution Approach 2:
The system incorporates dynamic adjustment capabilities including height adjustment systems for base plates and interchangeable base rings that can be changed according to the specific tire configuration. This dynamic adaptability allows the same equipment to maintain precision across different manufacturing scenarios without requiring multiple dedicated systems.
2Device complexity
If manual insertion and removal of separators and bead cores is used, then device complexity is reduced, but productivity and manufacturing precision are worsened
Solution Approach 1:
The device divides the processing function into multiple independent processing stations arranged on a rotatable plate, with each station capable of automatically performing specific operations on separators and bead cores. This segmentation enables parallel processing and automation while keeping individual station designs relatively simple.
Solution Approach 2:
The system incorporates automatic centering and positioning mechanisms that self-adjust to accommodate different separator and bead core configurations. The height adjustment systems and gripper drives enable automatic handling without requiring complex manual intervention, thereby increasing productivity while maintaining reasonable system complexity.
3Adaptability or versatility
If base rings of different diameters are used, then adaptability to different tire sizes is improved, but device complexity and operation time are increased
Solution Approach 1:
The system pre-configures multiple base rings with different diameters ready for quick exchange. The height adjustment systems are pre-programmed with position data for different tire sizes, allowing rapid reconfiguration without time-consuming measurements or complex setup procedures. This preliminary preparation minimizes changeover time while maintaining versatility.
4Productivity
If automated apex application is used for curved apexes, then productivity is improved, but manufacturing precision and stability are worsened due to tensile stresses
Solution Approach 1:
The system introduces separators as intermediary elements that play a crucial role in stabilizing curved apexes during automated application. The separators act as mediators between the apex and the bead core, distributing stresses evenly and preventing excessive tensile stress concentration. This intermediary approach enables automated processing while maintaining manufacturing precision and stability.
