Device for tension-free storage of sheet-like material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for tension-free storage and supply of web-shaped materials, such as textile or foam materials, face issues with material stress due to continuous support member movement, leading to surface irregularities and rejects during lamination.
Innovation Solution
A device with a feed device that introduces material stress-free between support members, where the support members are advanced only after a defined material quantity is reached, using sensors to control loop length and material detection for optimal storage and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If support members continuously move to feed material into the goods store, then material supply continuity is improved, but material stress increases causing surface irregularities
Solution Approach 1:
The support member is positioned in advance below the feed device and waits in a ready position before the material is fed. This preliminary positioning allows the material to be introduced stress-free first, and only after the material loop is formed does the support member advance to take over the material, thus avoiding stress during the critical feeding phase while maintaining continuous supply capability
Solution Approach 2:
A material loop is formed as an intermediary between the feed device and the support member. The material itself creates this loop structure that acts as a buffer, allowing the feed device to introduce material without direct contact with the support member during the critical stress-free feeding phase, thereby mediating between continuous supply requirements and stress-free material introduction
2Productivity
If support members advance continuously to maintain material flow, then production efficiency is improved, but material quality deteriorates due to stresses
Solution Approach 1:
The support member advances periodically rather than continuously - it waits in a ready position, then advances to take over the material loop, then waits again. This periodic action pattern allows intervals of stress-free material introduction followed by controlled advancement, maintaining production efficiency through rhythmic operation while ensuring material quality by eliminating stress during the feeding phases
Solution Approach 2:
The support member is positioned in advance below the feed device and waits in a ready position before the material is fed. This preliminary positioning allows the material to be introduced stress-free first, and only after the material loop is formed does the support member advance to take over the material, thus avoiding stress during the critical feeding phase while maintaining continuous supply capability
