Banknote Handling Machine Parallel Storage Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sheet handling machines take a long time to store sheets in a storage bag due to the inability to send new sheets from the transporting unit to the temporary storage unit while sheets are being stored in the storage bag.
Innovation Solution
The implementation of a banknote handling machine with a parallel processing mode that allows simultaneous storage operation and transport operation, enabling banknotes to be sent from the transporting unit to both temporary storage units, even when one is full, thereby preventing interruptions in the storage process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sheets are sent from the transporting unit to the temporary storage unit and then stored in the storage bag, then the sheets can be properly organized and stored, but new sheets cannot be sent to the temporary storage unit while it is full, causing long storage time
Solution Approach 1:
The patent divides the storage system into multiple temporary storage units (first temporary storage unit and second temporary storage unit) instead of using a single temporary storage unit. This segmentation allows the system to switch between different temporary storage units, enabling continuous operation without waiting for one unit to be emptied and reused.
Solution Approach 2:
The patent introduces a time dimension to the storage process by implementing parallel operations: while sheets are being stored from the first temporary storage unit to the storage bag, new sheets are simultaneously transported to the second temporary storage unit. This dimensional change transforms the sequential process into a parallel one, eliminating idle time.
2Device complexity
If a single temporary storage unit is used, then the structure is simple, but the storage operation must be interrupted when the unit is full
Solution Approach 1:
The patent segments the temporary storage function into multiple independent temporary storage units, allowing the system to maintain simple individual unit structures while achieving complex continuous operation capability through the combination of multiple units.
Solution Approach 2:
The patent implements a mechanism where one temporary storage unit is being used for storage operations while another is being prepared or emptied in parallel. The system switches between units, effectively discarding the limitation of a single unit's capacity by recovering its functionality through the other unit.

AI summary
In a sheet handling machine (for example, a banknote handling machine 10) including a plurality of mounting units, a controlling unit 80 controls a transporting unit 24 and temporary storage units 44 to perform parallel processing mode such that a storage operation for sending a sheet held by a first temporary storage unit 44 among the plurality of temporary storage units 44 to a storage member (for example, a banknote storage bag 34) and a transport operation for transporting the sheet from the transporting unit 24 to a second temporary storage unit 44 different from the first temporary storage unit 44 are performed in parallel.
