Paper Sheet Storage Device Orthogonal Sealing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper sheet storing units face issues with space efficiency due to the need for a wide space for sealing mechanisms and risk of adhesive degradation, leading to incomplete sealing and stacking failures during storage.
Innovation Solution
A paper sheet storing unit with a take-in unit and a storing unit featuring a first and second retention member that can be drawn orthogonally to seal the paper sheet storing bag, reducing space requirements and using a peel-off sheet to prevent adhesive exposure and degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first frame is drawn onto the front side twice (before and after sealing) to seal the pouch, then the pouch can be sealed and removed, but a wide space is required on the front side which cannot be ensured in many installation places
Solution Approach 1:
The patent changes the sealing mechanism from a linear front-side drawing motion to a vertical pressing motion. The pressing member moves vertically to press between the first and second frames, sealing the pouch without requiring extensive front-side space. This dimensional change resolves the space constraint while maintaining sealing functionality.
Solution Approach 2:
The patent replaces the complex two-stage mechanical drawing system with a simpler pressing mechanism. Instead of drawing the frame forward twice, a pressing member vertically presses between frames to achieve sealing, reducing mechanical complexity and space requirements.
2Ease of operation
If the adhesive surface is exposed during banknote storage, then the banknote can be easily stored, but the adhesive force is degraded by aging and the banknote may adhere to the adhesive surface
Solution Approach 1:
The patent applies preliminary action by pre-covering the adhesive surface with a release sheet before banknote storage. This prevents adhesive exposure and aging during the storage period, while still allowing easy banknote insertion. The release sheet is removed only when sealing is required.
Solution Approach 2:
The patent introduces a release sheet as an intermediary between the adhesive surface and the banknote. This intermediary layer prevents direct contact between the banknote and adhesive, preventing both adhesion issues and adhesive degradation, while allowing the storage operation to proceed smoothly.
3Productivity
If paper sheets are stored by free fall, then the storage process is simple, but stacking failures occur and the paper sheets may become upright, causing false full-state detection
Solution Approach 1:
The patent introduces a push-in member that dynamically adjusts during the storage process. The member pushes paper sheets horizontally into the pouch during free-fall storage, ensuring proper stacking orientation and preventing upright positions, while maintaining the simplicity and speed of the free-fall method.
Solution Approach 2:
The patent uses a push-in member as an intermediary mechanism between the paper sheet input and the pouch. This member ensures proper stacking by gently pushing sheets into correct orientation during the free-fall process, preventing stacking failures without compromising storage speed.
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
The solution enhances space efficiency and ensures complete sealing of the paper sheet storing bag while preventing adhesive exposure and degradation, thereby improving storage reliability and capacity.
Implementation Method 1
an adhesive surface is formed in an inner surface of the pouch, and the upper opening of the pouch is sealed by adhesion of the adhesive surface
Implementation Method 2
the banknote taken in the container is stored in the banknote storing bag by free fall using transport means

AI summary
First retention member 40 and second retention member 42 are disposed so as to be separately arrayed along a direction orthogonal to a drawing direction, in which the first retention member 40 and the second retention member 42 are drawn from paper sheet storing unit. Upper opening of paper sheet storing bag 50 is sealed when the first retention member 40 moves toward and abuts on the second retention member 42. The first retention member 40 and the second retention member 42 is drawable to outside from the paper sheet storing unit only when the first retention member 40 and the second retention member 42 abut each other.
