Tire Handling Device with Coordinated Pivotable Boom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tire handling devices have limited movement kinematics and reach, restricting their ability to access multiple tire vulcanizing machines due to fixed gripping tool distances and circular arc movements, which is costly and inefficient, especially when handling sensitive tires post-vulcanization.
Innovation Solution
A handling device with a pivotable boom supporting a gripping tool, featuring coordinated pivoting degrees of freedom that form a continuous movement path through coupling means, allowing extended reach and increased flexibility in gripping points, including the use of additional arms and indexing gears for enhanced movement coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a cantilever with fixed overhang length is used, then the structure is simple, but the travel distance of the gripping tool is limited
Solution Approach 1:
The cantilever is divided into two segments: a fixed first cantilever arm and a pivotable second cantilever arm. This segmentation allows the gripping tool to achieve extended travel distance by pivoting the second arm, while maintaining structural simplicity through the modular design.
Solution Approach 2:
The second cantilever arm is made pivotable relative to the first cantilever arm, introducing dynamic movement capability. This allows the gripping tool to adapt its position and extend its reach beyond the fixed overhang length, improving travel distance without requiring a completely complex reconfigurable structure.
2Adaptability or versatility
If a single pivot joint is used, then the device is simple, but the movement path is restricted to circular arc
Solution Approach 1:
The movement mechanism is segmented into two independent pivot joints: a first pivot joint connecting the cantilever to the base, and a second pivot joint connecting the gripping tool to the cantilever. This segmentation allows each joint to contribute independently to the overall movement, creating complex trajectories from simple circular arcs.
Solution Approach 2:
The system transitions from single-joint circular arc motion to two-degree-of-freedom motion by adding another pivot joint. This enables the gripping tool to move along more flexible paths that combine circular arcs, expanding the reachable workspace while maintaining mechanical simplicity.
3Adaptability or versatility
If the handling device is positioned close to the vulcanizing machine, then it can reach the treatment chamber, but it cannot access multiple machines
Solution Approach 1:
The handling device is segmented into a base portion positioned at the vulcanizing machine and a movable cantilever portion with the gripping tool. This segmentation allows the device to maintain a compact base while extending its reach through the pivotable cantilever, enabling access to multiple machines without increasing base complexity.
Solution Approach 2:
The cantilever is designed with pivot joints that enable dynamic adjustment of the gripping tool's position and orientation. This dynamic capability allows the same base unit to serve multiple vulcanizing machines by adapting its reach and positioning, eliminating the need for complex dedicated gripping tools for each machine.
4Manufacturing precision
If complex gripping tools are used for sensitive tires, then handling precision is improved, but cost and complexity increase
Solution Approach 1:
The gripping tool is made pivotable relative to the cantilever, providing dynamic adjustment capability. This allows precise positioning and orientation of the gripping tool to match the specific requirements of different tire types and handling scenarios, achieving high handling precision without requiring an overly complex dedicated tool for each case.
Solution Approach 2:
The pivotable gripping tool design creates a universal handling mechanism that can adapt to various tire types and handling requirements. The same basic gripping tool structure, when positioned and oriented differently through the pivot joints, can handle different tire configurations, reducing the need for multiple specialized complex tools.
