Sheet Storing Apparatus Banknote Collapse Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banknote storing mechanisms face issues with banknotes collapsing when the number of banknotes stored is small, leading to stacking and sealing failures in storage bags.
Innovation Solution
A sheet storing apparatus with a recognition unit to count banknotes, a holding section to support the storage bag, and a control section to manage the movement of a support section to prevent banknote collapse by adjusting the descent of the support stages based on the counted number of banknotes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the placing section is moved up and down to store banknotes in the storage bag, then the storage capacity is improved, but the banknotes collapse when the number of banknotes is small
Solution Approach 1:
The control section performs preliminary actions by moving the support section to a predetermined position before sealing the storage bag when the number of banknotes is detected to be small. This preliminary positioning prevents the banknotes from collapsing during the sealing process, ensuring stable stacking while maintaining storage capacity.
2Productivity
If the support section is moved quickly to the final position, then the storage speed is improved, but the banknotes collapse due to insufficient support
Solution Approach 1:
The control section dynamically adjusts the movement of the support section based on the number of banknotes detected. When the number of banknotes is small, the support section is moved to a predetermined position that provides adequate support. When the number of banknotes is large, the support section can be moved more quickly to the final position. This dynamic adjustment maintains both storage speed and sealing reliability.
3Productivity
If the storage bag is sealed immediately after placing banknotes, then the sealing efficiency is improved, but stacking failure occurs when banknotes are few
Solution Approach 1:
The control section uses feedback from the recognition unit that counts the number of banknotes to determine the appropriate sealing procedure. When the number of banknotes is detected to be small, the control section activates the drive section to move the support section to a predetermined position before sealing. This feedback-based control ensures stacking reliability while maintaining sealing efficiency by automating the conditional positioning action.
