Stepwise Conveyor Belt Layout for Tire Belt Rubber Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transmission of drive force from a conveyor to the tapered front portion of a rubber member is inefficient, leading to misalignment during the manufacturing of tire belts.
Innovation Solution
A tire belt manufacturing apparatus with a conveyer system comprising multiple conveyer belts disposed in a stepwise manner, driven by a single drive device, and equipped with pulleys of varying diameters and suction units, ensures effective transmission of drive force to the front end of the rubber member, reducing misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional conveyer with uniform conveyer belts is used, then the structure is simple, but the drive force is not transmitted to the tapered front portion of the rubber member, causing misalignment
Solution Approach 1:
The conveyer is segmented into multiple conveyer belts (first, second, third conveyer belts) with different configurations. The first conveyer belt has a longer conveyance unit extending closer to the front side, while the second and third conveyer belts have shorter conveyance units. This segmentation allows differential drive force application to different regions of the rubber member, ensuring the tapered front portion is properly engaged and aligned during conveyance.
Solution Approach 2:
Different conveyer belts provide different levels of drive force to different locations on the rubber member. The first conveyer belt, positioned to engage the front portion, provides stronger localized drive force where the tapered shape reduces contact area. This local quality adjustment ensures uniform drive force distribution across the rubber member's surface, preventing misalignment of the front portion.
2Reliability
If the conveyer belts are disposed in a stepwise manner with different positions, then drive force transmission to the front portion is improved, but the conveyer structure becomes more complex
Solution Approach 1:
The conveyer belts are arranged asymmetrically in a stepwise manner along the width direction of the rubber member. The first conveyer belt is positioned closer to the front side with a longer conveyance unit, while the second and third conveyer belts are positioned progressively closer to the back side with shorter conveyance units. This asymmetric arrangement matches the tapered geometry of the rubber member, ensuring reliable drive force transmission to the front portion while maintaining structural feasibility.
