Banknote Storage Orientation Control for Polymer Note Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Banknote processing systems face challenges in properly storing and feeding banknotes with strip-like members made of polymer or metal materials, as these banknotes are less bendable in certain orientations, leading to improper storage and feeding issues due to differing friction coefficients and orientations.
Innovation Solution
A banknote processing apparatus with a transport unit and storage units that can receive and store banknotes in both long-edge and short-edge orientations, utilizing a control unit to select the appropriate storage destination based on the banknote's orientation and type, ensuring proper storage and feeding.

Engineering Contradiction Analysis
1Volume of moving object
If a winding-type storage module receives a banknote in the short-edge orientation, then the banknote can be stored in a compact form, but the storage fails when the banknote is less bendable in that orientation due to strip-like members
Solution Approach 1:
The system changes the storage orientation parameter from fixed short-edge orientation to variable orientation (short-edge or long-edge) based on the banknote's bendability characteristics, allowing reliable storage of banknotes with strip-like members regardless of their bending properties
Solution Approach 2:
The storage system dynamically adapts its configuration by selecting between different storage units (short-edge orientation storage unit and long-edge orientation storage unit) based on real-time detection of banknote characteristics, making the system flexible rather than rigid
2Productivity
If a stacking-type storage module receives a banknote in the short-edge orientation, then the banknote can be stacked efficiently, but feeding fails when the strip-like member position causes different friction coefficients
Solution Approach 1:
The system changes the feeding orientation parameter based on the position of strip-like members, selecting between short-edge and long-edge orientation feeding to maintain consistent friction coefficients and reliable feeding regardless of strip-like member positioning
Solution Approach 2:
The feeding mechanism dynamically adjusts its operation by directing banknotes to appropriate storage units based on detected strip-like member positions, ensuring consistent friction characteristics and reliable feeding across all banknote types
3Device complexity
If the transport unit transports all banknotes in a fixed orientation, then the transport path is simple, but both storage and feeding fail for banknotes with strip-like members
Solution Approach 1:
The transport system dynamically adjusts banknote orientation during transport based on detected characteristics (strip-like member position, bendability), directing banknotes to appropriate storage units while maintaining relatively simple transport paths through controlled orientation changes
Solution Approach 2:
The system changes the transport orientation parameter from fixed to variable, allowing the transport unit to adjust banknote orientation (short-edge or long-edge leading) based on banknote characteristics, ensuring reliable storage and feeding without significantly complicating the transport path

AI summary
A banknote processing apparatus capable of properly storing and dispensing a banknote is provided. The banknote processing apparatus includes: a transport unit that transports a banknote; a long-edge orientation storage unit that receives and stores, in a first orientation, the banknote transported by the transport unit, the first orientation being an orientation in which a short edge of the banknote is a leading edge thereof; a short-edge orientation storage unit that receives and stores, in a second orientation, the banknote transported by the transport unit, the second orientation being an orientation in which a long edge of the banknote is a leading edge thereof; and a control unit that selects, by controlling the transport unit, a storage destination for the banknote transported by the transport unit, from among any of the long-edge orientation storage unit and the short-edge orientation storage unit.
