Solution Overview
Problem
Existing methods for winding flat goods, such as center and peripheral winders, face challenges in preventing deformation and surface damage due to weight contact and occupational safety concerns during high-speed production.
Innovation Solution
A hybrid method and device that initially operates as a peripheral winder with the winding core on a conveyor belt, then transitions to a center winder by lifting the core using linear, hydraulic, or pneumatic drives, allowing safe and deformation-free winding of flat goods over extended lengths without stopping the production line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a center winder is used to avoid deformation by keeping goods off the conveyor belt, then manufacturing precision is improved, but device complexity increases due to the self-drive mechanism
Solution Approach 1:
The patent applies the dynamics principle by enabling the winding system to transition between two operational modes: initially operating as a peripheral winder with the sleeve on the conveyor belt, then dynamically switching to center winder mode by lifting the sleeve off the belt using a lifting device. This dynamic adaptation allows the system to optimize for both ease of operation and manufacturing precision at different stages of the winding process.
2Ease of operation
If a peripheral winder is used for ease of operation and manual setup, then ease of operation is improved, but manufacturing precision deteriorates due to contact-induced deformations
Solution Approach 1:
The patent applies the dynamics principle by enabling the winding system to transition between two operational modes: initially operating as a peripheral winder with the sleeve on the conveyor belt, then dynamically switching to center winder mode by lifting the sleeve off the belt using a lifting device. This dynamic adaptation allows the system to optimize for both ease of operation and manufacturing precision at different stages of the winding process.

AI summary
The present invention relates to a method for winding flat material, comprising the steps of: • at a first height of a winding receptacle (2) relative to a flat material to be wound, rotatingly picking up the flat material to be wound onto the winding receptacle (2), wherein the rotation of the winding receptacle (2) is generated by feeding the flat material to be wound up, • moving the winding receptacle (2) from the first height to a second height relative to the flat material to be wound up above the first height, and • at the second height of the winding receptacle (2) relative to the flat material to be wound up, rotatingly picking up the flat material to be wound up onto the winding receptacle (2), wherein the rotation of the winding receptacle (2) is generated by a first drive.
