Banknote Handling Machine Automatic Classification Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper sheet handling machines require manual classification of paper sheets after retrieval, leading to time and labor inefficiencies, and lack versatility in using sheets stored in multiple storage units for different purposes.
Innovation Solution
A paper sheet handling machine with an upper assembly for intake and ejection, a transporting unit with recognition capabilities, and a lower assembly with multiple storage units controlled by a unit that sorts sheets based on predetermined conditions, allowing for automatic classification and storage of sheets for specific uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple storage bags are mounted in one paper sheet handling machine, then the storage capacity is improved, but the paper sheets are stored in a mixed state requiring manual classification afterward
Solution Approach 1:
The recognition unit identifies paper sheet types before storage, and the controlling unit pre-classifies them to specific storage bags based on predetermined conditions. This preliminary classification action eliminates the need for manual sorting after storage, resolving the contradiction between increased storage capacity and time loss from manual classification.
Solution Approach 2:
The system performs automatic classification through the recognition unit and controlling unit, which autonomously sort paper sheets to appropriate storage bags without human intervention. This self-service mechanism resolves the contradiction by making the system self-sufficient in classification tasks, eliminating manual labor time while maintaining multi-bag storage capacity.
2Quantity of substance
If multiple storage bags are mounted in one paper sheet handling machine, then the storage capacity is improved, but the versatility of using sheets for different purposes is reduced
Solution Approach 1:
Each storage bag is assigned a specific function or purpose through the controlling unit's predetermined conditions. For example, different bags can be designated for different paper sheet types, denominations, or usage purposes. This local quality differentiation allows each storage location to serve a specific function, thereby maintaining versatility while utilizing multiple storage bags for increased capacity.
Solution Approach 2:
The system can adapt the function of each storage bag based on predetermined conditions, allowing the same hardware configuration to serve multiple different purposes. The controlling unit can dynamically assign different classification criteria to different storage bags, enabling the system to handle various paper sheet types and purposes simultaneously, thus achieving both high storage capacity and versatility.
3Device complexity
If manual classification of paper sheets is required after retrieval, then the device complexity is reduced, but the operator burden increases
Solution Approach 1:
The recognition unit and controlling unit automatically perform classification tasks without operator intervention. The system serves itself by autonomously identifying paper sheet types and directing them to appropriate storage bags, thereby reducing operator burden while the added complexity of automatic recognition and control systems is justified by the elimination of manual classification labor.
4Productivity
If automatic classification and sorting control is implemented, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The manual mechanical sorting process is replaced with an automatic system using recognition units (optical/electronic) and electronic control units. This substitution of mechanical manual sorting with automated recognition and control systems increases productivity while the added electronic complexity is offset by the elimination of manual labor and improved sorting speed and accuracy.

AI summary
A paper sheet handling machine (for example, a banknote handling machine 10) includes a lower assembly 16 that includes a plurality of storage units (such as a banknote storage bag 34 or banknote storage cassette 36) for storing the paper sheet sent from a transporting unit 24 of an upper assembly 14 and a controlling unit 50 configured to perform control to sort the paper sheet, to be sent from the transporting unit 24 of the upper assembly 14 to the lower assembly 16, to each of the storage units based on a predetermined classification condition designated in advance.
