Banknote Strapping Device Cradle Anvil Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banknote strapping devices face inefficiencies in stacking and strapping processes, particularly in handling large volumes of banknotes and ensuring consistent strapping quality across varying note conditions.
Innovation Solution
A banknote strapping device featuring a cradle and plunger assembly that moves banknotes from a stacking position to a strapping position, using a vertically or horizontally moving anvil to secure the banknotes with a strap, allowing for efficient stacking and strapping within a single escrow region, and incorporating fold units for secure binding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If banknotes are stacked and strapped in separate regions with multiple transfers, then handling flexibility is improved, but processing time increases and productivity decreases
Solution Approach 1:
The patent combines the stacking region and strapping region into a single integrated escrow region. The cradle serves as both a stacking platform and a strapping platform, eliminating the need for separate regions and multiple transfers. This merging of functions directly resolves the contradiction by maintaining handling flexibility through the cradle's dual role while dramatically improving processing speed by eliminating transfer steps.
Solution Approach 2:
The cradle is designed as a multi-functional component that performs both stacking and strapping operations. It can receive banknotes from the transport path, stack them vertically, and then perform strapping operations on the same platform. This universal design allows the system to maintain adaptability for different operations while improving productivity through continuous processing without transfers.
2Ease of operation
If banknotes are transferred multiple times between stacking and strapping positions, then operational flexibility is improved, but the number of operations increases and time consumption increases
Solution Approach 1:
By merging the stacking and strapping positions into a single escrow region with the cradle serving both functions, the patent eliminates multiple transfers. The cradle remains in place while performing both operations sequentially, reducing the number of operations and time consumption while maintaining ease of operation through the streamlined process.
Solution Approach 2:
The system enables continuous processing by eliminating idle transfer time. While the cradle stacks banknotes, the strapping mechanism prepares materials, and vice versa, creating a continuous workflow. This continuity reduces time consumption while maintaining operational flexibility through coordinated actions.
3Device complexity
If a linear arrangement of positions is used, then device complexity is reduced, but the footprint area increases
Solution Approach 1:
The patent transitions from a linear horizontal arrangement to a vertical three-dimensional arrangement. The cradle stacks banknotes vertically in the escape region, and the strapping anvil moves vertically to perform operations. This dimensional change reduces the horizontal footprint while maintaining simplicity through the vertical stacking and strapping sequence.

AI summary
A banknote strapping device comprises a banknote floor moveable generally parallel to a first linear direction from a floor home position to a floor strapping position, a banknote cradle having a cradle stacking position, and a plunger assembly having an anvil, wherein the plunger assembly is configured to move the anvil generally parallel to the first linear direction from an anvil home position on a first side of the cradle stacking position of the banknote cradle to an anvil strapping position located on a second side of the cradle stacking position. When a first predetermined number of banknotes have been stacked on the banknote cradle, a stack of banknotes that had been stacked thereupon is transferred to the banknote floor positioned at the floor home position, wherein the anvil moves the stack of banknotes and the banknote floor to a strapping position at which the stack of banknotes is strapped.
