Floating Feed Channel for Collision-Tolerant Sheet Coiling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winding devices for strip-shaped material face collisions during spool changes, leading to potential damage to the feed channel, spool, and other components, due to insufficient extension of the feed channel, which can result in collisions with the spool or other machine parts.
Innovation Solution
The feed channel is mounted in a floating manner relative to the plate, allowing it to move and 'give in' during collisions, with limited movement to prevent extensive damage, and is equipped with a holding element and centering part for stabilization and alignment, along with sensors for collision detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the feed channel is rigidly fixed to the plate, then structural stability is improved, but damage occurs during collisions with spools or machine parts
Solution Approach 1:
The feed channel is designed with a floating mounting that allows dynamic movement relative to the plate during collisions, while maintaining stability during normal operation. The holding element provides controlled restraint that permits impact absorption through relative motion.
Solution Approach 2:
The floating mounting arrangement pre-configures the feed channel to absorb impact energy through controlled movement before damage can occur. The holding element is positioned to provide restraint only after normal operational limits are exceeded.
2Object-affected harmful factors
If the feed channel is mounted in a floating manner, then collision damage is minimized, but positioning precision deteriorates
Solution Approach 1:
The mounting transitions from a static rigid connection to a dynamic floating connection that maintains precision during normal operation but allows movement during collisions. The holding element provides controlled restraint to maintain positioning accuracy.
Solution Approach 2:
The system changes the degree of freedom of the feed channel based on operational conditions. During normal operation, the floating mounting maintains precise positioning with minimal play. During collision, the mounting allows controlled displacement to absorb impact energy.
3Manufacturing precision
If the feed channel is extended further into the spool, then winding precision is improved, but collision risk increases
Solution Approach 1:
The feed channel's extended position for precise winding is maintained during normal operation, while the floating mounting provides a safety mechanism that allows the channel to move back upon collision, preventing damage despite the extended exposure.

Function Achieved in This Case
This design minimizes damage during collisions by allowing the feed channel to absorb impact, ensuring quick recovery and preventing material bending or breakage, while enabling efficient operation and alignment post-collision.
Implementation Method 1

AI summary
A device (100) for winding strip-shaped material onto at least one spool (10) has at least one feeding device (20) for feeding the strip-shaped material, wherein the feeding device (20) has at least one feeding channel (22) and at least one plate (42) on which the feeding channel (22) rests at least partially. By having the feeding channel (22) floating relative to the plate (42), a device for winding strip-shaped material is created which minimizes damage in the event of a collision with the feeding channel (22).
