Banknote Handling Apparatus Reject Sorting and Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banknote handling apparatuses face inefficiencies in rejected banknote re-depositing tasks due to mixing of proper and improper banknotes, require separate equipment for recognition and counting, and struggle with high-speed processing while increasing environmental load and noise.
Innovation Solution
A banknote handling apparatus with a recognition unit, deposit acceptability judging unit, reject reason identifying unit, and dispensing processing unit that sorts and dispenses rejected banknotes based on identified reasons, allowing for efficient re-depositing and reducing environmental impact through mode switching and optimized transport speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rejected banknotes are discharged to a single reject unit without separation, then the device structure is simple, but the operator cannot efficiently perform re-depositing tasks because proper and improper banknotes are mixed
Solution Approach 1:
The reject unit is segmented into multiple sub-units (first reject unit for improper banknotes, second reject unit for proper banknotes requiring re-depositing). This segmentation allows operators to efficiently identify and re-deposit only the necessary banknotes while maintaining a manageable device structure through modular design.
2Measurement precision
If separate equipment is used for banknote recognition and counting, then the recognition accuracy is improved, but the device complexity and space requirements increase
Solution Approach 1:
The recognition unit and counting unit are merged into a single integrated system that processes banknotes through a shared transport path. The recognition unit identifies banknote characteristics while the counting unit simultaneously tallies them, achieving accurate recognition and counting without requiring separate equipment installations.
3Productivity
If banknotes are transported at high speed, then the processing productivity is improved, but the environmental load and noise increase
Solution Approach 1:
The transport unit operates with periodic motion patterns, adjusting speed dynamically during different processing phases. High speed is used during banknote transfer between units, while lower speeds are employed during recognition and counting operations, thereby maintaining productivity while reducing noise and environmental load during sensitive operations.

AI summary
A banknote handling apparatus that performs a depositing handling or a depositing/dispensing handling by transporting banknotes along a transport path includes a recognizing unit that recognizes an inserted banknotes; a deposit acceptability judging unit that determines, based on a recognition result obtained by the recognizing unit, whether the banknotes is acceptable for deposit; a reject reason identifying unit that identifies a reject reason of rejected banknotes that is determined to be unacceptable for deposit by the deposit acceptability judging unit; and a dispensing handling unit that sorts and dispenses the rejected banknotes based on the reject cause identified by the reject cause identifying unit.
