Banknote Storage Bag Pressing Mechanism for Stable Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper sheet handling machines experience instability in stacking banknotes due to the tilted position of notes at the bottom of storage bags, leading to an unstable stacked state.
Innovation Solution
A paper sheet storage mechanism that includes a holding unit, a pressing unit, and a control unit to shape the bottom portion of the storage bag into a flat state, preventing tilting and ensuring stable stacking by pressing the bag from inside before inserting banknotes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the bottom portion of the storage bag is merely spread out on the platform without pressing, then the storage process is simple and quick, but the banknotes stacked on the bottom portion tilt with respect to the horizontal direction, making the stacked state unstable
Solution Approach 1:
The pressing unit presses the bottom portion of the storage bag into a flat shape before banknotes are stacked, preparing the surface in advance to prevent tilting and ensure stable stacking of banknotes
2Stability of the object's composition
If a pressing unit is added to press the storage bag from inside, then the banknotes can be stacked stably without tilting, but the device complexity increases
Solution Approach 1:
The pressing unit is integrated into the existing storage mechanism and serves multiple functions: pressing the bottom portion of the storage bag flat, supporting the bag during stacking, and maintaining stability throughout the stacking process, thereby reducing the need for additional separate components

AI summary
A paper sheet storage mechanism (e.g., a banknote storage mechanism 32) is provided with a pressing unit (e.g., pressing plate 46) which advances into a storage bag (e.g., banknote storage bag 34) held by a holding unit (e.g., holding member 36) and presses a portion of the storage bag from inside toward a placement unit (e.g., stage 40), thereby bringing a portion of the storage bag placed on the placement unit into a state in which paper sheets are stackable thereon. Before paper sheets are sent into the storage bag, the pressing unit is caused to advance into the storage bag and press the portion of the storage bag toward the placement unit.
