Reduction Roll Rail Mechanism for Easy Roller Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method for replacing rollers in a reduction roll apparatus requires large equipment like a hoist crane, making the process complicated and costly.
Innovation Solution
A roll exchange mechanism that includes a first rail member, placement parts, receiving parts, and an opening in the apparatus frame, allowing the roll unit to be easily inserted and removed without the need for large equipment, using a simple structure and a roll changing cart.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a hoist crane is used to replace rollers, then the rollers can be replaced, but the equipment becomes large and complicated
Solution Approach 1:
The support frame is divided into a first support frame and a second support frame that can be detached from each other. This segmentation allows the roll unit to be separated into manageable components that can be handled and replaced using simple equipment rather than requiring a large hoist crane.
Solution Approach 2:
The roller is extracted from the support frame by detaching the roll unit. The opening in the apparatus frame allows the roll unit to be pulled out and removed easily. This extraction enables replacement without needing complex lifting equipment.
2Productivity
If a hoist crane is used to replace rollers, then the rollers can be replaced, but the work becomes complicated
Solution Approach 1:
The support frame is designed with detachable connections that allow dynamic reconfiguration. The first and second support frames can be separated and reattached, enabling flexible and simple replacement operations without fixed complex mechanisms.
Solution Approach 2:
The opening in the apparatus frame serves as an intermediary space that facilitates the removal and installation of roll units. This simple structural feature enables easy access and exchange without requiring complex lifting or positioning equipment.
3Adaptability or versatility
If rollers are replaced using traditional methods, then replacement is possible, but large equipment is required
Solution Approach 1:
Dividing the support frame into separable first and second support frames creates a lightweight, adaptable system. This segmentation eliminates the need for heavy hoist cranes while maintaining the capability to replace rollers effectively.
Solution Approach 2:
The detachable support frame design and opening structure provide a universal replacement mechanism that can handle various roll units. This multi-functional design replaces the need for specialized heavy equipment with a versatile, lightweight system.
