Cash Cassette Separator Module Rough Surface Note Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
New notes in automatic teller machines often stick together, leading to improper dispensing and increased rejection rates, as sensors struggle to verify the correct number of notes due to their adherence.
Innovation Solution
A cash cassette system with separator modules featuring a rough surface, including nonplanar ridges or hooks, is introduced to loosen individual notes from each other as they move towards the pick-up module, ensuring proper alignment and separation before dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If new notes are stored in a stack in the cash cassette, then the notes are ready for dispensing, but the notes stick together causing improper dispensing and increased rejection rates
Solution Approach 1:
The separator module with rough surface is positioned in the path of notes before they reach the pick-up module. The rough surface performs preliminary separation action on the stack of notes, loosening individual notes from each other before dispensing occurs. This preliminary action prevents the sticking problem from affecting the actual dispensing operation.
2Measurement precision
If sensors verify the correct number of notes, then dispensing accuracy is improved, but sticky notes cause verification failure and routing to reject box
Solution Approach 1:
The separator module performs preliminary separation of notes before they reach the sensing and verification area. By loosening individual notes from the stack in advance, the notes pass through the sensor verification process individually rather than as stuck bundles, enabling accurate counting and verification.
3Ease of operation
If manual separation and restocking is performed, then sticky notes are handled, but productivity is reduced and operational time increases
Solution Approach 1:
The separator module enables the system to automatically separate sticky notes without requiring manual intervention. The rough surface continuously performs separation as notes pass through, allowing the cash cassette to service itself and maintain high productivity without operational staff needing to manually separate and restock notes.
4Reliability
If a rough surface separator module is added to loosen individual notes, then note separation is improved, but device complexity increases
Solution Approach 1:
Instead of making the entire cash cassette structure complex, the separator module applies local quality by adding a rough surface only in the specific area where note separation is needed. The rough surface is localized to the separator module component, which is integrated into the existing cassette structure, minimizing overall complexity while achieving effective separation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution significantly reduces the rejection rate of notes by ensuring each note is dispensed individually, improving the reliability of the dispensing process and minimizing manual separation needs.
Implementation Method 1
The rough surface engages the particular note edge of the plurality of notes as the plurality of notes are pushed onto the one or more separator modules by the push plate. The rough surface loosens individual notes among the plurality of notes from each other as the plurality of notes move across the one or more separator modules toward the pick-up module.

AI summary
A cash cassette includes a housing, a pick-up module, a push plate, and one or more separator modules. The housing has a dispense end, a floor, and a size suitable to store multiple notes. Each note has a particular note edge. The pick-up module is disposed at the dispense end of the housing and is configured to transfer one note at a time out of the housing. The push plate is movably disposed inside the housing and is configured to bias the notes against the pick-up module. The separator modules are disposed on the floor of the housing proximate to the pick-up module. Each separator module has a rough surface that engages the particular note edges as the notes are pushed onto the separator modules by the push plate. The rough surface loosens individual notes from each other as the notes move across the separator modules toward the pick-up module.
