Banknote Processing Jam Recovery via Segmented Conveyance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Banknote processing devices face inefficiencies in handling jams during direct banknote conveyance, as existing technologies do not effectively manage the conveyance of banknotes from the deposit aperture to banknote cassettes, leading to processing delays and lack of control over abnormal banknotes.
Innovation Solution
A banknote processing device with an insertion aperture, banknote verification section, and controller that separates and verifies banknotes, stopping conveyance upon jam detection and directing verified banknotes to storage sections while ejecting unverified ones, allowing for continued stacking even during jams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If banknotes are conveyed directly from the insertion aperture to banknote cassettes without temporary holding, then cash processing time is shortened, but control over abnormal banknotes during conveyance is lost
Solution Approach 1:
The patent segments the conveyance control into multiple paths: a first conveyance path for normal banknotes leading to banknote cassettes, and a second conveyance path for abnormal banknotes leading to an abnormal banknote discharge aperture. The controller divides the banknote stream based on verification results, enabling direct processing while maintaining control over abnormal notes through separate handling paths.
2Ease of operation
If jammed banknotes are handled by manual operation, then processing resumes, but productivity is reduced and abnormal banknote handling is incomplete
Solution Approach 1:
The system performs self-service by automatically detecting jams through sensors, identifying the location of jammed banknotes, and conveying them to the discharge aperture without requiring manual intervention. The controller autonomously manages the recovery process, maintaining productivity while resolving jams.
3Productivity
If all banknotes are conveyed to banknote cassettes regardless of verification status, then processing speed increases, but abnormal banknotes may be incorrectly stored
Solution Approach 1:
The system performs preliminary verification of banknotes at the verification section before final conveyance to banknote cassettes. Based on verification results, the controller determines the appropriate conveyance path in advance, ensuring abnormal banknotes are routed to the discharge aperture while normal banknotes proceed to storage, maintaining both speed and accuracy.

AI summary
A banknote processing device that stacks banknotes in a banknote storage section even when a jam occurs. The device has an insertion aperture, a verification section, the storage section and a controller. The aperture separates and feeds inserted banknotes. The verification section verifies the banknotes fed from the aperture. The banknotes are stacked in the storage section. The controller controls conveyance of the banknotes conveyed from the aperture to the verification section such that, depending on verification results, the banknotes are conveyed directly to the storage section. When a jam occurs during conveyance of the banknotes, the controller stops the separation and feeding of the banknotes from the aperture, and controls conveyance such that banknotes for which the storage section has been set as a conveyance destination by the verification section are conveyed directly to the storage section and banknotes for which no conveyance destination has been set are ejected.
