Paper Money Processing Device Movable Piece Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing paper money processing devices face issues with stacking paper money when it is inserted at a deviated position, leading to incomplete storage due to jutting ends being folded and not fully pushed into the storage box.
Innovation Solution
A paper stock processing device with a movable piece that emerges and sinks perpendicular to the conveyance direction to align and store paper stock, ensuring proper stacking even if it is misaligned, along with a conveyance mechanism that uses a guide piece and control unit to manage the storage and ejection of paper stock through a shared insertion and ejection slot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the pressurizer width and paper money intake port aperture width are slightly shorter than the paper money width, then the paper money can be pushed into the storage box, but when the paper money position is deviated in the width direction, the jutting part becomes long and the paper money cannot be fully pushed into the storage box
Solution Approach 1:
The patent introduces a movable piece that moves in the width direction (perpendicular to the conveyance direction) to compensate for position deviations. This adds a dimensional adjustment capability that allows the system to handle paper money at various positions within a certain range, resolving the contradiction between precise stacking and tolerance to deviation.
Solution Approach 2:
The movable piece performs preliminary alignment action by moving to cover the jutting part of the paper money before the pushing operation. This preliminary positioning ensures that even if the paper money is deviated, it will be properly aligned during the pushing process, enabling full insertion into the storage box.
2Productivity
If a separate ejection slot is provided, then paper stock can be ejected efficiently, but the device thickness increases
Solution Approach 1:
The patent makes the insertion slot serve dual functions by providing a return conveyance path that allows paper stock to be ejected through the same slot. This multi-functionality eliminates the need for a separate ejection slot, reducing device thickness while maintaining ejection efficiency.
Solution Approach 2:
The insertion slot and ejection function are merged into a single structural component. The return conveyance path connects the storage unit back to the insertion slot, combining what would traditionally be separate slots into one, thereby reducing the overall device thickness.

AI summary
A paper money processing device is provided with: a storage unit for forming a storage space in which paper money is layered and stored; a conveyance mechanism for conveying paper money to the storage unit; and a movable piece capable of emerging and sinking the storage space, the movable piece being provided in a direction orthogonal to the conveyance direction of the paper money conveyed by the conveyance mechanism. Conveyance is stopped in a position where the trailing end part of the paper money to be conveyed to the storage unit by the conveyance mechanism is facing the moveable piece, the trailing end part of the paper money in a position facing the moveable piece is thereafter moved to the storage space side and the paper money is layered and stored in the storage space by the emerging/sinking operation of the movable piece.
