Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a prism-like suction drum is used to convey separator material, then the separator material can be held and conveyed, but the tension acting on the separator material changes continuously due to corner rotation, causing unstable separator shapes and reduced processing precision
Solution Approach 1:
The patent replaces the prism-like suction drum with a cylindrical rotor. The cylindrical shape eliminates corners that cause tension variations, providing continuous uniform curvature around the entire perimeter. This ensures consistent tension distribution on the separator material during rotation, stabilizing the separator shape and improving manufacturing precision while maintaining conveyance functionality.
2Device complexity
If separator bands are delivered to receiving stage and pressing plate at fixed timing, then the system operates simply, but arbitrary timing adjustments cannot be made, causing processing difficulties and waste
Solution Approach 1:
The patent implements a controllable rotor system that can dynamically adjust its rotation speed and timing. This dynamic control capability allows the separator cutting and conveyance timing to be flexibly adjusted according to different processing requirements, enabling arbitrary timing adjustments while maintaining operational efficiency and reducing waste.
3Productivity
If cutting is performed while separator material is held on the rotor surface, then continuous processing is enabled, but the separator shape becomes unstable due to varying tension during rotation
Solution Approach 1:
The cylindrical rotor provides uniform curvature throughout its rotation, ensuring that the separator material experiences consistent tension distribution at all points during the cutting and conveyance process. This eliminates the shape instability caused by corner rotations in prism-like drums, maintaining separator shape consistency while enabling continuous processing.

AI summary
A separator conveying device includes a columnar rotor that holds a continuously supplied separator material on an outer circumferential surface thereof; a cutting unit that cuts the separator material while the separator material is held on the outer circumferential surface of the columnar rotor into a separator with a predetermined shape; and a control unit configured to control a suction force in a slip region. The separator cut out by the cutting unit is conveyed by rotating the columnar rotor while maintaining a state where the separator is held on the outer circumferential surface of the columnar rotor. The outer circumferential surface of the columnar rotor is formed into a suction region where the separator material or the separator is sucked and the slip region where the suction force is switched between sucking and fixing the separator material, and slipping the separator material while sucking the separator material.
