Banknote Transport Layout for Accurate Rejection Counting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Banknote deposit and withdrawal apparatuses in retail markets face challenges due to complex structures, high manufacturing costs, and inaccurate counting of rejection banknotes, particularly when multiple sheets overlap during temporary storage.
Innovation Solution
A simplified structure with integrated deposit and withdrawal parts, drum-shaped temporary and rejection parts, and vertically stacked reflux cassettes, utilizing sensors on transportation paths to distinguish and store reflux and non-reflux banknotes, and separate storage for normal and rejection banknotes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex structure with multiple modules is used to perform various functions, then the functionality and versatility of the apparatus is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The transport path is designed to perform multiple functions including transporting deposit banknotes, transporting withdrawal banknotes, and transporting rejection banknotes. The same transport path structure is used across different operational modes (deposit, withdrawal, rejection handling), eliminating the need for separate dedicated transport paths for each function and thereby reducing overall device complexity while maintaining versatility
Solution Approach 2:
The intake part serves dual purposes by being capable of introducing both deposit banknotes and withdrawal banknotes through the same structure. The transport path integrates multiple transportation functions into a single unified system, merging what would traditionally require separate modules into one cohesive structure
2Adaptability or versatility
If a long and complicated transport path is used to handle various banknote operations, then the versatility of the apparatus is improved, but the device complexity and volume increase
Solution Approach 1:
The transport path is designed as a universal structure that handles deposit banknotes, withdrawal banknotes, and rejection banknotes using the same physical path. This multi-functional design allows the apparatus to perform various operations without requiring additional dedicated transport paths, thereby maintaining operational versatility while minimizing the total length and complexity of the transport system
3Quantity of substance
If multiple sheets of rejection banknotes overlap during temporary storage, then the storage capacity is improved, but the measurement precision of the banknote count deteriorates
Solution Approach 1:
The discrimination section performs preliminary detection and counting of rejection banknotes while they are being transported and before they are rolled up and stored in the temporary storage part. By measuring the banknotes in advance (during transport) rather than after storage, the system accurately determines the count even when the banknotes are subsequently stacked and rolled together in the drum-shaped storage, thereby maintaining measurement precision while achieving compact storage
Solution Approach 2:
The system replaces physical counting methods (such as manually counting stacked banknotes) with sensor-based detection during transport. The discrimination section uses detection mechanisms to identify and count banknotes as they pass through, substituting mechanical counting with automated sensing, which provides accurate count information even when the banknotes are later stored in an overlapping rolled configuration

AI summary
A banknote deposit and withdrawal apparatus according to an embodiment includes a deposit and withdrawal part having a space, through which a banknote is inserted or received during deposit and withdrawal, a deposit banknote discrimination section that discriminates a type and abnormality of a deposit banknote by a plurality of sensors provided on a transportation path along which the banknote deposited through the deposit and withdrawal part is transported, a temporary holding part provided on one side of the deposit and withdrawal part and having a drum-shaped structure in which the banknote discriminated as a non-reflux banknote in the deposit banknote discrimination section is temporarily stored, a rejection part provided on one side of the temporary holding part and having a drum-shaped structure in which the banknote discriminated as a deposit rejection banknote in the deposit banknote discrimination section is temporarily stored, a deposit-dedicated cassette which stores the non-reflux banknote, which is temporarily stored in the temporary holding part, transported thereto when the deposit is received, a plurality of reflux cassettes which are stacked at a lower side of the deposit-dedicated cassette and in which the banknote discriminated as a reflux banknote in the deposit banknote discrimination section is stored separately according to the type of the banknote, and the transportation path along which the deposited or withdrawn banknote is transported.
