Tire Drum Rotation Inversion for Ribbon Stacking Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire production methods face issues such as energy loss, risk of device failure, and feed deficiency due to heavy equipment and speed restrictions when winding and stacking ribbon strips around a core.
Innovation Solution
A tire production device configuration where the supply unit is fixed, and the drum is aligned with the sticking position, allowing high-speed rotation and improved stacking pattern freedom, reducing the need for abrupt movements along the X-Y axes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the supply unit is moved against the rotating core, then the ribbon strips can be supplied to the core, but the heavy weight of the extrusion molding machine causes energy loss, device failure risk, and feed deficiency
Solution Approach 1:
Instead of moving the heavy supply unit (extrusion molding machine) against the rotating core, the invention inverts the approach by keeping the supply unit fixed and moving the core (via turning table and moving table) to the supply position. This eliminates the need to move heavy equipment, thereby reducing energy consumption and improving device reliability.
2Adaptability or versatility
If the core is made turnable and moved along X-Y axes to wind ribbon strips, then the stacking angle can be changed, but high-speed movement along X-Y axes is required which creates speed restrictions
Solution Approach 1:
The invention inverts the conventional approach by keeping the supply unit fixed and rotating the core on a turning table. This allows the core to achieve high-speed rotation for rapid stacking while the turning table provides adaptability for different stacking angles and patterns, eliminating the need for high-speed linear movement along X-Y axes.
Solution Approach 2:
The invention introduces dynamic elements including a rotatable drum for high-speed rotation, a turning table for angular positioning, and a moving table for X-Y axis positioning. This dynamic configuration allows the system to adapt to different stacking patterns while maintaining high stacking speeds through rotational motion rather than linear movement.
3Productivity
If the drum rotates at high speed with aligned turning center axis, then the stacking speed improves and freedom of stacking pattern increases, but the configuration complexity increases
Solution Approach 1:
The invention segments the positioning and stacking functions into separate modules: a turning table for angular positioning, a moving table for linear positioning, and a rotatable drum for high-speed stacking. This segmentation allows each component to be optimized independently, achieving high productivity while managing overall system complexity through modular design.
