Optical Cashbag Level Detection for Automated Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current banknote acceptor systems lack a simple, low-cost, and efficient method to accurately determine the level of banknotes in a cashbag without manual intervention, leading to inefficient cash collection and increased operational costs due to capacity limitations and the need for tamper-evident features.
Innovation Solution
A sensing arrangement that includes an optical proximity sensor to detect the presence and position of banknotes within a cashbag, measuring the distance of banknotes from the sensor and activating a sealing mechanism when a predetermined threshold is reached, ensuring accurate detection and proper installation of the cashbag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inspection is used to determine cashbag capacity, then operational simplicity is maintained, but productivity decreases due to frequent operator intervention
Solution Approach 1:
The patent replaces manual mechanical inspection with an optical sensing system. An optical sensor detects the presence and level of banknotes in the cashbag by detecting light reflection or absorption patterns, converting a mechanical inspection task into an automated optical measurement system.
Solution Approach 2:
The cashbag monitoring system performs self-assessment of its own capacity status. The optical sensor continuously monitors the cashbag contents and automatically triggers alerts or sealing actions when capacity thresholds are reached, eliminating the need for external operator intervention.
2Loss of time
If cashbags are collected at preset time intervals, then operational simplicity is maintained, but loss of time increases due to unnecessary collections and incomplete cashbag utilization
Solution Approach 1:
The system implements continuous feedback monitoring of cashbag contents through optical sensing. The sensor provides real-time information about banknote accumulation levels, enabling the system to automatically determine when cashbag collection is actually needed based on real capacity status rather than fixed schedules.
Solution Approach 2:
The optical sensor detects approaching capacity thresholds before the cashbag is completely full, allowing advance warning and preparation for collection. This preliminary detection prevents overflow and enables optimized collection timing.
3Reliability
If tamper-evident features are added to cashbags, then reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces physical tamper-evident mechanisms with an automated optical monitoring and sealing system. The sensor detects cashbag status and triggers automated sealing actions, providing security through process control rather than physical features.
Solution Approach 2:
The optical sensor serves multiple functions: detecting banknote presence, measuring cashbag fill level, monitoring cashbag installation status, and triggering sealing operations. This multi-functionality consolidates security and monitoring features into a single integrated system.
4Productivity
If cashbag capacity is increased beyond current cashbox limits, then productivity is improved, but device complexity increases due to need for larger containment structures
Solution Approach 1:
The patent changes the monitoring parameter from fixed physical capacity limits to dynamic optical detection thresholds. The system can adapt to different cashbag sizes and fill levels by adjusting sensor detection parameters, allowing flexible capacity management without structural modifications to the cashbox.

AI summary
This disclosure relates to a cashbag sealing system (100). The system comprises a banknote transport mechanism (203) operable to transport a banknote to a storing unit (206, 208). The storing unit (206, 208) includes a banknote storing bag (202) detachably coupled to the storing unit (206, 208), and an escrow plate (216) operable to escrow the banknote before the banknote transported to the storing unit (206, 208) is stored in the banknote storing bag (202), wherein the escrow plate (216) is operable to move from a horizontally extending hold position to a downwardly or obliquely downwardly extending release position, and wherein the banknote transported to the storing unit (206, 208) is escrowed on the escrow plate (216) when the escrow plate (216) is located at the hold position. The system further comprises a sensor (212) configured to detect a presence of the banknote on the escrow plate (216), and measure a level of banknotes in the banknote storing bag (202).
