Banknote Handling Apparatus Inclined Transport Foreign Matter Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banknote handling machines face issues with foreign matter, such as coins or clips, getting jammed in the transporting unit when mixed with banknotes, as they are not effectively separated during the handling process.
Innovation Solution
A paper sheet handling apparatus that inclines stacked paper sheets at an angle using a second transporting unit with sandwiching members to release foreign matter, which includes a mechanism to detect and remove foreign objects by causing the banknotes to be inclined and then releasing them from the sandwiching members, allowing foreign matter to fall out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stacked paper sheets are fed one by one by the banknote feeding unit without inclining, then the feeding process is simple, but foreign matter mixed with the paper sheets cannot be removed and gets jammed in the transporting unit
Solution Approach 1:
The second transporting unit inclines the stacked banknotes before they are fed to the feeding unit, performing a preliminary action to remove foreign matter. This prevents jamming in advance by causing foreign objects to fall out due to gravity when the banknotes are inclined, rather than waiting for jamming to occur during feeding.
Solution Approach 2:
The invention introduces a new dimension by inclining the stacked banknotes at a specific angle using the second transporting unit. This dimensional change from horizontal to inclined position enables foreign matter removal through gravity, adding a new operational dimension to the transporting process without significantly complicating the overall device structure.
2Reliability
If foreign matter removal mechanism is added to the banknote handling system, then jamming is prevented, but device complexity increases
Solution Approach 1:
The second transporting unit serves multiple functions: it transports the stacked banknotes from the first transporting unit to the feeding unit, and simultaneously inclines the banknotes to remove foreign matter. This multi-functionality allows foreign matter removal without adding a separate dedicated mechanism, thereby preventing jamming while minimizing increases in device complexity.
Solution Approach 2:
The system uses the existing motion of the second transporting unit to achieve foreign matter removal. By simply changing the inclination angle during normal transport operation, the system removes foreign matter using gravity and the banknotes' own weight, rather than requiring additional active mechanisms or energy-consuming devices.
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
Prevents jamming by effectively removing foreign matter from the banknotes before they are fed into the feeding unit, ensuring smooth operation and reducing production costs by eliminating the need for additional mechanisms to align banknotes.
Implementation Method 1
the second transporting unit causes the stacked paper sheets being in the horizontal state to be inclined at an angle to a horizontal plane

AI summary
A paper sheet handling apparatus (for example, a banknote handling apparatus (10)) includes a first transporting unit (30) configured to transport a plurality of paper sheets in a stacked state in a horizontal state, a feeding unit (40) configured to feed the paper sheets one by one, and a second transporting unit (50) configured to transport to the feeding unit (40) the stacked paper sheets transported by the first transporting unit (30). The second transporting unit (50) causes the stacked paper sheets being in the horizontal state to be inclined at angle to a horizontal plane.
