Banknote Storage Bag Sealing Control via Pressing Plate Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banknote handling apparatuses experience poor sealing when storing wrinkled banknotes, leading to incomplete sealing and potential extraction of banknotes through unsealed portions during the heat-sealing process.
Innovation Solution
A sheet handling apparatus with a controller that manages the movement of a pressing plate and stages to ensure a predetermined distance is maintained between the pressing plate and the stage, preventing the expansion of banknotes and ensuring adequate sealing by adjusting the position of the stages and pressing plate based on the number of banknotes stored, thereby preventing contact with the heating member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the pressing plate presses wrinkled banknotes and then retracts, then the banknotes are compressed to increase storage capacity, but the banknotes expand in the layering direction causing poor sealing when the opening is heat-sealed
Solution Approach 1:
The controller stops the banknote storing operation before the pressing plate retracts completely, maintaining a predetermined distance between the pressing plate and the stage. This preliminary action prevents the banknotes from expanding enough to contact the heating member, thereby preventing poor sealing before it can occur.
Solution Approach 2:
The system determines the storage bag is full based on the distance measurement between the pressing plate and stage during the pressing operation, before retraction occurs. This preliminary determination allows the sealing process to proceed with adequate sealing area reserved, preventing the expansion problem.
2Quantity of substance
If the stage is positioned to maximize banknote storage space, then more banknotes can be stored, but the sealing area around the opening becomes insufficient when banknotes expand
Solution Approach 1:
The distance detection device continuously monitors the distance between the pressing plate and the stage, providing feedback to the controller. Based on this feedback, the controller determines when the storage bag is full and adjusts the stopping position to ensure adequate sealing area is maintained, balancing storage capacity with sealing requirements.
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 poor sealing by maintaining a sufficient sealing area around the opening of the storage bag, even when storing wrinkled banknotes, ensuring that the banknotes are securely stored without being extracted through unsealed portions.
Implementation Method 1
the opening of the storage bag is heat-sealed

AI summary
A controller of a sheet handling apparatus (for example, banknote handling machine) stops an operation of storing a sheet in a storage bag (for example, banknote storage bag) on the condition that the number of sheets (for example, banknotes) received by a number information receiver is less than a predetermined number, when a distance between a receiver (for example, each stage) and a presser (for example, pressing plate) that is pressing the sheets stored in a storage bag which is supported by a support (for example, each holding member), toward the receiver, is greater than a predetermined distance.
