Actuatable Multidisc Roller for Uniform Tire Pressure Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire production methods face challenges in evenly applying pressure across diverse tire sizes and configurations using disc rollers, leading to inconsistent bonding and productivity issues due to varying tire profiles.
Innovation Solution
A multidisc roller system with actuatable disc assemblies and demi-discs that allow for adjustable pressure distribution and alignment, enabling uniform bonding across different tire profiles by using a frame with linearly displaceable arms and rotatable demi-discs with guide grooves and bearings, ensuring consistent contact points and pressure application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple disc rollers are used to bond tire layers, then bonding adhesion is improved, but pressure distribution becomes uneven across diverse tire profiles
Solution Approach 1:
The disc roller system employs actuators that enable dynamic adjustment of each disc's position and pressure application. The actuatable arms can independently displace to accommodate varying tire profiles, allowing the system to adapt pressure distribution in real-time rather than relying on fixed positioning. This dynamic capability resolves the contradiction by maintaining both strong bonding and uniform pressure across diverse tire configurations.
Solution Approach 2:
The system changes physical parameters of the disc roller assembly by allowing individual discs to be positioned at different distances from the drum surface through actuated arms. This parameter adjustment enables each disc to apply optimal pressure to different sections of the tire profile, ensuring uniform pressure distribution while maintaining effective bonding across the entire tire structure.
2Adaptability or versatility
If disc distance is increased to accommodate pronounced profiles, then adaptability to diverse tire sizes is improved, but landing force consistency deteriorates
Solution Approach 1:
The bonding system is segmented into multiple independently actuatable disc assemblies rather than using a single rigid roller. Each disc assembly can be independently positioned and actuated, allowing the system to accommodate diverse tire profiles while maintaining consistent landing force at each contact point. The segmentation enables localized adjustment of force application to match varying profile requirements.
Solution Approach 2:
Each disc assembly incorporates actuatable arms that can dynamically adjust the position and orientation of individual discs. This dynamic adjustment capability ensures that even when discs are spaced further apart to accommodate pronounced profiles, each disc maintains optimal contact and consistent landing force on its designated section of the tire profile.
3Device complexity
If fixed disc positioning is used to simplify the mechanism, then device complexity is reduced, but productivity decreases due to inconsistent bonding
Solution Approach 1:
The actuated disc roller system serves multiple functions: it can accommodate various tire sizes and profiles, adjust pressure distribution dynamically, and maintain consistent bonding across diverse configurations. This multi-functionality justifies the increased complexity by delivering superior bonding consistency and versatility that fixed positioning cannot achieve, ultimately improving productivity through reduced reconfiguration needs.

AI summary
A tire production device is provided for pressure bonding products that are presented in a product profile (120) on a forming drum surface. The device includes a multidisc roller system (100) having a frame (102) relative to which a plurality of disc assemblies (104, 104′) are disposed along a common axis. Each disc assembly includes an actuatable arm 106 that is linearly displaceable relative to the frame, a pair of removably attached demi-discs (110, 110′) and a bearing (112) that accommodates rotation of the demi-discs (110). An actuator is associated with each disc assembly (104, 104′) for bringing the disc assemblies (104, 104′) into and out of contact with the product profile (120). A method is also provided for assembling tire components for the manufacture of tires.
