Drum Storage System for Handling Retracted Banknotes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for handling notes of value have limited retract compartments, making it difficult to handle multiple retracts efficiently and requiring significant installation space, which becomes a constraint after a few retract transactions.
Innovation Solution
The device employs a drum storage system with two foil belts wound around a drum, allowing for the storage of a large number of retracted notes, and serves both as an intermediate and permanent storage, maintaining operational capacity beyond initial retracts while saving space by separating counterfeit notes and rare denominations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If retract compartments are provided in known devices, then non-removed notes of value can be stored separately, but the number of retracts is limited and installation space is consumed
Solution Approach 1:
The drum storage is designed to serve multiple functions: it acts as both an intermediate storage for notes awaiting confirmation and a permanent storage for retracted notes. This multi-functionality eliminates the need for separate retract compartments, allowing multiple retracts to be performed while consuming minimal installation space.
Solution Approach 2:
The invention extracts the retract function from dedicated retract compartments and integrates it into the drum storage system. By taking out the need for separate retract compartments and combining their function with the intermediate storage, the system achieves unlimited retracts without additional space consumption.
2Ease of operation
If retract compartments are provided, then non-removed notes can be stored, but only a limited number of retracts (2-3) can be handled before the device becomes non-operational
Solution Approach 1:
The drum storage serves dual purposes as both intermediate and permanent storage, ensuring the device remains operational for multiple retracts. The large capacity of the drum storage prevents the device from becoming non-operational after just 2-3 retracts, maintaining reliability while enhancing ease of operation.
Solution Approach 2:
The drum storage is pre-configured with sufficient capacity to handle multiple retracts before any retract operation begins. This preliminary preparation ensures that the device can accommodate several retracts without becoming non-operational, maintaining continuous reliability.
3Ease of operation
If multiple retract compartments are provided to handle several retracts, then more retracts can be performed, but installation space requirement increases
Solution Approach 1:
The invention merges the intermediate storage and permanent storage functions into a single drum storage unit. This combination eliminates the need for multiple separate retract compartments, allowing the system to handle multiple retracts while maintaining compact installation space.
Solution Approach 2:
The drum storage is designed as a universal storage solution that performs both intermediate and permanent storage functions. This multi-functionality replaces what would traditionally require multiple separate compartments, reducing the overall installation space while enabling multiple retracts.

AI summary
Shown is a device for handling notes of value, with an input/output compartment, a pull-off and separating device, an intermediate storage unit comprising a drum storage, at least one cash box, a transport device for the transport of notes of value between the afore-mentioned units, and a control unit. The control unit is configured to control the transport device such that notes of value that are to be stored in the cash box are fed to the drum storage and are intermediately stored thereat, and these notes of value are again taken from the intermediate storage unit after receipt of a confirmation information, are fed to the cash box and are stored therein.
