Banknote Accumulating Device Impeller Pressing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Banknote accumulating devices face a decrease in storage capacity due to folded or wrinkled banknotes, which requires a pressing mechanism to maintain capacity, but this increases device size and complexity.
Innovation Solution
A paper sheet accumulating device with an impeller and support mechanism, including a first rotation shaft, a support member, a second rotation shaft, and a biasing member, that allows the impeller to press banknotes with a constant force, maintaining storage capacity without the need for a large and complex pressing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a pressing member and drive mechanism are provided to suppress decrease in storage capacity, then storage capacity is maintained, but device size increases and structure becomes complicated
Solution Approach 1:
The impeller is designed to perform dual functions: conveying banknotes to the accumulating part and pressing the accumulated banknotes to maintain storage capacity. By making the impeller movable toward and away from the accumulating part, it can switch between its conveying function and pressing function, eliminating the need for a separate pressing member and drive mechanism.
Solution Approach 2:
The conveying function and pressing function are merged into a single impeller mechanism. The impeller's ability to move toward the accumulating part allows it to combine the roles of a dedicated conveyor and a dedicated pressing member, thereby simplifying the overall device structure while maintaining storage capacity.
2Quantity of substance
If a pressing member is provided to suppress decrease in storage capacity, then storage capacity is maintained, but device size increases
Solution Approach 1:
The impeller serves multiple purposes: it conveys banknotes and also acts as a pressing mechanism when moved toward the accumulating part. This multi-functionality eliminates the need for additional pressing components, thereby preventing an increase in device size while still maintaining storage capacity.
Solution Approach 2:
The pressing function is extracted from a separate pressing member and integrated into the impeller itself. By removing the need for a dedicated pressing mechanism, the device size is reduced while the storage capacity is maintained through the impeller's pressing action.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively suppresses the decrease in storage capacity caused by deformed banknotes, simplifies the device structure, and prevents jamming by applying a consistent pressing force, while allowing for efficient banknote accumulation and retrieval.
Implementation Method 1
a biasing member that biases the support member in a direction of the impeller moving toward the paper sheets accumulated in the accumulating part

AI summary
A paper sheet accumulating device includes an accumulating part in which paper sheets are accumulated, an impeller that sends the paper sheets to the accumulating part, and a support mechanism that supports the impeller. The support mechanism includes a first rotation shaft that supports the impeller rotatable, a support member provided with the first rotation shaft, a second rotation shaft that supports the support member rotatable in a direction of the support member moving toward and away from the accumulating part, and a biasing member that biases the support member in a direction of the impeller moving toward the paper sheets accumulated in the accumulating part.
