Lever Mechanism for Separating Winding Shafts in Nonwoven Winders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fleece winders face challenges in efficiently separating winding shafts to minimize friction and energy consumption during the winding process, leading to potential damage and increased operational costs.
Innovation Solution
A fleece winder device that uses a lever mechanism to locally separate winding shafts from the magazine, allowing for easy transportation to a waiting position with reduced friction and energy requirements, incorporating a connecting shaft and a bearing surface that lifts the shaft away from the magazine, and a stop edge to prevent contact with neighboring shafts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the winding shaft is removed from the magazine without local separation, then the structure remains simple, but friction and energy consumption increase due to contact with neighboring shafts
Solution Approach 1:
The lever mechanism is activated before the winding shaft is removed from the magazine to preemptively lift and separate the shaft. This preliminary action prevents contact with neighboring shafts during removal, reducing friction and energy consumption while maintaining structural simplicity
Solution Approach 2:
The lever acts as an intermediary element between the winding shaft and the magazine floor. By introducing this intermediate component, the shaft can be lifted and transported without direct contact with the magazine or neighboring shafts, reducing friction while adding minimal structural complexity
2Reliability
If the winding shaft is separated from neighboring shafts during removal, then damage risk is reduced, but additional force and energy are required
Solution Approach 1:
The lever mechanism performs the separation action before the shaft is fully removed from the magazine. By lifting the shaft off the floor and creating clearance from neighboring shafts in advance, the system protects against damage during transport while minimizing the force required compared to forcing separation during removal
Solution Approach 2:
The manual or forceful separation process is replaced by a mechanical lever system that uses rotational motion to lift and position the shaft. This substitution reduces the direct force required by converting linear separation force into a mechanical advantage system
3Use of energy by moving object
If the lever lifts the winding shaft away from the magazine floor, then friction is reduced, but the mechanism complexity increases
Solution Approach 1:
The lever serves as a simple intermediary component that provides the lifting function. By using this single mechanical element instead of a complex automated system, the patent reduces friction through shaft elevation while maintaining minimal mechanism complexity
Solution Approach 2:
The lever mechanism is designed to be self-actuating or easily actuated, where the removal motion itself can trigger the lifting action. This self-service approach reduces the need for additional complex control systems while achieving the friction reduction benefit
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces the energy needed for operation, minimizes the risk of damage to the winding shafts, and allows for a more efficient and cost-effective winding process by enabling the use of lower-energy drives and preventing contact-induced damage.
Implementation Method 1
The lever in turn is arranged on the connecting shaft in a rotationally fixed manner... when the shaft rotates in a predetermined, first direction, the lever is rotated to a predetermined end position
Implementation Method 2
the lever is rotated to a predetermined end position such that the contact surface of a floor... points the way against the first winding shaft. The first direction thus leads to the lever lifting one winding shaft away from the magazine
Implementation Method 3
The bearing surface is inclined towards the ground in the direction of a contact roller of the fleece winder. This makes it possible for one winding shaft to roll past the magazine on the support surface in the direction of the contact roller
Implementation Method 4
The increased effort can result from the contact and the resulting friction between one winding shaft and the neighboring winding shaft and/or the impact against an end stop of the magazine
