Shingled Banknote Storage Spool Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for storing value documents, such as bank notes, are inefficient and do not allow for easy post-processing of rejected or classified documents, as they require unwinding and re-threading of storage foils, leading to complex and space-inefficient storage solutions.
Innovation Solution
The apparatus employs a stacker wheel and transport device to arrange value documents in a shingled manner, allowing them to be wound onto a storage spool with storage foils, enabling efficient storage and easy removal for further processing, with a control device adjusting the overlap and speed to optimize storage space and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If value documents are stored by winding stacks onto a spool core with storage foil, then storage is achieved, but storage space utilization is inefficient and retrieval is complex
Solution Approach 1:
The invention segments the storage process into two distinct phases: a winding phase where documents are accumulated in stacks onto the spool, and a pay-out phase where documents are dispensed individually in a shingled configuration. This segmentation allows the storage system to optimize for both compact storage and easy retrieval by switching between configurations, resolving the contradiction between storage efficiency and retrieval simplicity.
Solution Approach 2:
The storage system dynamically changes the configuration of stored documents between stacked and shingled arrangements based on operational requirements. During winding, documents are stacked for compactness; during retrieval, they are paid out in a shingled manner for easy access. This dynamic reconfiguration resolves the contradiction by adapting the storage structure to different functional states.
2Volume of stationary object
If value documents are stored in stacked configuration on spool, then storage is compact, but documents cannot be easily removed and processed singly
Solution Approach 1:
The system performs a preliminary winding action to compactly store documents in stacks during the winding phase. When retrieval is needed, the pre-wound stacks are then paid out in a shingled configuration that enables easy single-document removal. This preliminary compact storage followed by controlled dispensing resolves the contradiction between storage compactness and retrieval ease.
3Reliability
If storage foil is used to wind value document stacks, then documents are contained, but unwinding and re-threading is required for post-processing
Solution Approach 1:
The storage system dynamically transitions between winding and pay-out modes, allowing the storage foil to serve different functions at different times. During winding, the foil contains and organizes documents into compact stacks. During pay-out, the foil automatically feeds documents in a shingled sequence that eliminates the need for unwinding and re-threading operations, thus maintaining containment while reducing processing time.
Solution Approach 2:
The system maintains continuous useful action by ensuring that during the pay-out phase, documents are automatically fed one after another in a shingled configuration directly to the verification device. This continuous feed eliminates interruptions for unwinding and re-threading, maintaining both document containment and continuous processing flow.

AI summary
An apparatus and a corresponding method involve storing value documents, in particular bank notes, to a storage device and to a value-document processing system. A stacker wheel is arranged to receive value documents and dispense them one after the other. A transport device is arranged to receive the value documents dispensed one after the other by the stacker wheel and to transport them in such a way that the value documents come to lie on top of each other in a shingled manner. A storage device for storing the value documents lying on top of each other in a shingled manner is provided.
