Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fleece winders face safety issues during the transport of winding shafts from the waiting position to the winding position, as disruptions can cause the shaft to become detached and fall, posing risks to operators and potentially damaging the equipment.
Innovation Solution
A fleece winder design incorporating a holding section, a transport section with a guide surface that absorbs the weight of the winding shaft, and a locking mechanism to ensure safe movement, reducing the risk of detachment and maintaining control during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the winding shaft is transported horizontally between rollers on a floor level surface, then the transport mechanism is simple, but the winding shaft can become detached and fall in case of disruption, creating safety hazards
Solution Approach 1:
The patent transitions the transport surface from a horizontal floor level to a vertically oriented guide surface. The guide surface extends upward from the floor, creating a vertical dimension for transport. This dimensional change ensures the winding shaft remains constrained against gravity and cannot fall away in case of disruption, while still maintaining a relatively simple transport mechanism using the guide surface and transport section.
2Reliability
If gripping elements apply high gripping force to secure the winding shaft, then the winding shaft cannot detach, but the mechanical stress on the fleece winder increases
Solution Approach 1:
The guide surface is designed to absorb and support the weight of the winding shaft throughout the transport process. By providing a support surface that counteracts gravity, the system eliminates the need for high gripping forces from the transport section. The guide surface bears the load, allowing the winding shaft to be secured reliably without imposing excessive mechanical stress on the fleece winder's gripping elements and structure.
3Object-affected harmful factors
If the running surface is positioned close to the floor, then the fall height is minimized, but the winding shaft can still leave the transport section in case of malfunction
Solution Approach 1:
The guide surface is configured to extend upward from the floor level, creating a vertical barrier that contains the winding shaft within the transport section. By positioning the guide surface vertically rather than horizontally at floor level, the system prevents the winding shaft from leaving the transport section laterally, while the guide surface itself provides the containment boundary that eliminates the need for additional containment structures.
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
The design significantly reduces the risk of the winding shaft falling or becoming detached, enhancing operator safety and minimizing potential damage by maintaining the winding shaft on the guide surface throughout the transport process, while also simplifying the construction and reducing mechanical stress on the fleece winder.
Implementation Method 1
The guide section has a running surface pointing essentially away from a floor on which the fleece winder is placed and is designed to absorb the weight of the winding shaft
Implementation Method 2
the winding shaft to be wound comes into frictional contact in the area of the fleece with a contact roller

AI summary
A nonwoven winder (1) comprises a holding section (3), a transport section (100), and a guide section (20). The holding section (3) is designed to accommodate a winding shaft (7). The guide section (20) has a running surface (21) that extends substantially away from a base on which the nonwoven winder (1) is placed and is designed to support the weight of the winding shaft (7). The transport section (100) and the guide section (20) are designed to move the winding shaft (7) from the holding section (3) along the running surface (21) toward a winding position (4) in which the nonwoven winder (1) is configured to wind the winding shaft (7) with a nonwoven fabric located on a contact roller (8) of the nonwoven winder (1).A method for operating the nonwoven winder (1) comprises a step of engaging the winding shaft (7) located in the holding section (3) at least from one side facing away from the contact roller (8) of the nonwoven winder (1) by means of the locking section (130) of the nonwoven winder (1). Subsequently, the movement section (120-123) is moved towards the contact roller (8). Furthermore, a step of detecting the presence of a state in which the winding shaft (7) has reached the winding position (4) is carried out. If this state is detected, the locking section is stopped.
