Currency Handling Device Vault Door Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper currency handling devices face issues with feeding paper currency, especially when the number of sheets is small, leading to potential contact with the wall of the feeding port and mechanical stress on clerks due to large arm movements, and there is a need for improved compactness and security.
Innovation Solution
A paper currency handling device with a vane drive member that contacts the paper currency to adjust its attitude and a dual transportation path system allowing for efficient feeding and compact design, including a vault for secure storage and discrimination units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of sheets of paper currency deposited is small, then the self weight correction of folding marks and bending is insufficient, but the paper currency may contact the wall face at the feeding port and feeding stops
Solution Approach 1:
A guide member is introduced as an intermediary component between the paper currency and the feeding port wall. This guide member prevents direct contact between the paper currency and the wall face, eliminating the feeding stoppage issue without requiring complex mechanical correction mechanisms. The guide member simply guides the paper currency along a proper path, maintaining feeding reliability while keeping the device simple.
2Ease of operation
If a large up and down motion of the arm is needed in casting paper currency, then the paper currency depositing unit can be positioned lower, but a large physical load is applied to the clerk
Solution Approach 1:
The paper currency depositing unit is positioned at a height that creates an equipotential working condition for the clerk, eliminating the need for large up and down arm motions. The unit is mounted on the vault door at a height that allows the clerk to deposit paper currency with minimal arm movement, thereby reducing physical load while maintaining ease of operation.
3Reliability
If the paper currency depositing unit and withdrawing unit are accommodated separately from the storing unit, then security is improved, but the apparatus height increases
Solution Approach 1:
The paper currency depositing unit and withdrawing unit are positioned in the horizontal dimension on the vault door, rather than stacking them vertically. This dimensional reorganization allows separate accommodation of depositing and withdrawing functions while maintaining compact vertical height. The vault door acts as a horizontal platform that accommodates multiple units without increasing apparatus height, thus preserving security while controlling dimensions.
4Force
If the paper currency depositing unit is positioned to reduce clerk arm movement, then physical load on clerk is reduced, but the apparatus height may increase
Solution Approach 1:
The depositing unit is positioned horizontally on the vault door at an optimal height, utilizing the horizontal dimension for unit placement rather than vertical stacking. This allows the unit to be at a height that minimizes clerk arm movement without increasing the overall apparatus height, as the vault door provides horizontal space for accommodation.

AI summary
In order to improve the ability to feed paper currency from a deposit unit and to reduce the height of the device, this paper currency handling device (100) has a paper currency recognition unit (170) and a paper currency storage unit (200) (which does not include a deposit unit (120) and a withdrawal unit (140)) accommodated within a chassis section (112) of a vault (110), so that deposited paper currency is transported to the paper currency storage unit (200) and withdrawn paper currency is transported from the paper currency storage unit (200) as the paper currency passes through the chassis section (112). When the paper currency (B) is fed to a feed path unit (124) connecting the deposit unit (120) and an upstream deposit path (181), the vanes (129) of impellers (128) make contact with the paper currency (B) retained in the deposit unit (120), with the contact being on the feed path unit (124) side.
