Stage Roll Replacement Carriage Without Floor Rack Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing corrugating roll unit replacing apparatus requires a drive pinion on the floor surface and a rack on the corrugating roll unit, leading to a complex structure and increased manufacturing costs.
Innovation Solution
A corrugating roll unit replacing apparatus with a replacement carriage that includes a connection device, a locking hook, and a drive device, allowing for simplified movement and connection of the corrugating roll unit without the need for a movement unit on the transporting carriage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a drive pinion on the floor surface and a rack on the corrugating roll unit are used for replacement, then the corrugating roll unit can be moved and replaced, but the structure becomes complex and manufacturing cost increases
Solution Approach 1:
The patent extracts the movement function from the transporting carriage and relocates it to a separate replacement carriage. The replacement carriage includes a drive mechanism with a motor, rack, and pinion that are integrated into its own structure, removing the need for complex floor-mounted pinions and carriage-mounted racks. This separation simplifies both the transporting carriage and the replacement carriage individually.
Solution Approach 2:
The replacement carriage acts as an intermediary device between the transporting carriage and the corrugating roll unit. It provides the necessary drive mechanism to move the corrugating roll unit during replacement operations, without requiring the transporting carriage itself to have complex movement capabilities. The replacement carriage temporarily assumes the movement function during replacement operations.
2Ease of operation
If a drive pinion on the floor surface and a rack on the corrugating roll unit are used for replacement, then the corrugating roll unit can be moved and replaced, but manufacturing cost increases
Solution Approach 1:
The patent extracts the expensive drive mechanism from the floor installation and the transporting carriage, concentrating it in a dedicated replacement carriage. This allows for more efficient use of components and reduces the overall manufacturing cost by eliminating redundant structures.
Solution Approach 2:
The replacement carriage is designed as a multi-functional device that can handle multiple corrugating roll units of different types. It includes a storage space that can accommodate various roll units and a universal drive mechanism that can replace any of them, reducing the need for multiple specialized systems.
