Banknote Handling Apparatus Sorting by Issuance Origin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banknote handling apparatuses cannot sort banknotes by their issuing country, even when the same currency is used across multiple countries, and fail to differentiate between fit and unfit notes from different issuing countries.
Innovation Solution
The banknote handling apparatus recognizes the issuance origin of banknotes, including the issuing country, financial institution, and printing bureau, and sorts them accordingly using a system that identifies specific identification letters or marks on the banknotes to determine the stacking destination based on their issuance origin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If banknotes are sorted by currency type and denomination using conventional technology, then sorting by basic categories is achieved, but sorting by issuing country is not possible when the same currency is used across multiple countries
Solution Approach 1:
The patent segments the sorting process into multiple hierarchical levels: first by currency type, then by denomination, and finally by issuing country. This segmentation allows the system to handle banknotes with the same currency and denomination from different countries by creating separate sorting categories for each country, thus resolving the limitation of conventional single-level sorting systems
Solution Approach 2:
The system performs preliminary recognition of identification information (such as country codes or specific mark positions) on banknotes before the actual sorting process. By pre-identifying the issuing country through optical recognition of specific positions or marks on the banknotes, the system prepares the data structure needed for subsequent country-based sorting, enabling differentiated handling of banknotes from different countries
2Productivity
If all fit notes are stacked together without sorting by issuance origin, then stacking efficiency is improved, but the ability to collect and reuse only specific country's notes is lost
Solution Approach 1:
The patent implements a dynamic sorting configuration where the stacking destination can be flexibly assigned based on the banknote's identified issuing country. The system can dynamically adjust which stacking unit receives banknotes from which country, allowing financial institutions to optimize for either efficiency (consolidating all fit notes) or selective collection (separating by country) depending on operational requirements
3Measurement precision
If conventional recognition systems are used, then basic banknote attributes are identified, but issuance origin differentiation is not achieved
Solution Approach 1:
The patent introduces an intermediary recognition step that specifically targets identification information such as country codes or specific marks on banknotes. This intermediary layer processes optical data to extract country-specific identifiers before the final sorting decision is made, acting as a bridge between basic optical recognition and country-based sorting requirements

AI summary
The object is to recognize an issuance origin of a banknote of the same currency, and to sort banknotes according to an issuance origin. A banknote handling apparatus includes a receiving unit that receives a plurality of banknotes, a transport unit that transports the banknotes received in the receiving unit one by one, a plurality of stacking units that stack the banknote transported by the transport unit, a recognition unit that recognizes identification information indicating an issuance origin of the banknote transported by the transport unit, and a control unit that controls to sort and stack each of the banknotes of one currency in one of the plurality of stacking units corresponding to the issuance origin based on the identification information recognized by the recognition unit.
