Thin Metal Strip Winding with Leader Connection for Shorter Cycles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thin metal strip winding methods have long process cycles due to the manufacturing and winding process being sequential, which is inefficient and desires a shorter cycle.
Innovation Solution
A method and system that involves causing a thin metal strip to fly from a flight tube, cutting and grasping a portion, connecting it to a leader on a winding roll, and winding it up simultaneously, using a cutting-grasping unit, connecting unit, and winding unit to achieve continuous manufacturing and winding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a thin metal strip is manufactured and then wound up around a winding roll to be collected, then the thin metal strip can be collected for further processing, but the process cycle becomes long
Solution Approach 1:
The patent merges the manufacturing process and winding process into a single integrated operation. The thin metal strip is manufactured and wound up around the winding roll simultaneously in one continuous motion, eliminating the time delay between manufacturing and winding that exists in conventional sequential processes.
Solution Approach 2:
The patent implements continuous useful action by maintaining the thin metal strip in a flying state from the manufacturing stage through the winding stage without interruption. The strip is continuously fed from the flight tube, cut, connected to the leader, and wound up in an unbroken sequence, maximizing productivity and minimizing idle time.
2Ease of operation
If a thin metal strip is mounted directly to a winding roll, then the winding process can begin, but the operation becomes complex and safety risks increase
Solution Approach 1:
The patent segments the thin metal strip into two distinct parts: a flying portion that is continuously manufactured and fed, and a leader portion that remains on the winding roll. This segmentation allows the flying portion to be connected to the leader in a controlled manner rather than mounting the entire strip directly to the roll, simplifying the operation and reducing safety risks.
Solution Approach 2:
The leader acts as an intermediary element between the flying portion of the thin metal strip and the winding roll. The leader remains fixed on the winding roll while the flying portion is connected to it, facilitating the winding process without requiring direct mounting of the entire strip to the roll, thereby reducing operational complexity and improving safety.
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 approach significantly shortens the process cycle time and reduces the need for a large stock space, enhancing safety and ease of winding by avoiding direct mounting of the strip to the winding roll.
Implementation Method 1
a thin strip (thin film) with a small thickness is manufactured by rapidly cooling and solidifying a molten metal by a single-roll process

AI summary
A thin metal strip winding method includes: a step of causing a thin metal strip to fly from a flight tube; a cutting and grasping step of cutting and grasping any portion of the thin metal strip flying from the flight tube; a thin metal strip connecting step of connecting the any portion of the thin metal strip cut and grasped in the cutting and grasping step and a leader as a ribbon, the leader being a to-be-connected portion of another thin metal strip remaining on a winding roll set on a winding roll rotation unit of a winder that winds up the thin metal strip; and a thin metal strip winding step of winding up the ribbon around the winding roll by causing the winding roll rotation unit to rotate.
