Banknote Stacking Apparatus Paper Shifting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cash recycling and handling apparatuses are prone to edgefold or breakage of banknotes during the switchover process of outputting and inputting banknotes.
Innovation Solution
A sheet medium stacking and separating apparatus is designed with a frame, a supporting plate, and a paper shifting mechanism. The apparatus includes a storage cavity with a paper inlet and outlet, and a separation mechanism comprising a separating roller, a gate roller, and a pickup roller. The supporting plate moves along the stacking direction and has an output and receiving position, with the paper shifting mechanism adjacent to the paper outlet to prevent collision with the inner wall during the receiving process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the supporting plate moves to the receiving position without paper shifting mechanism, then the structure is simpler, but the banknotes collide with the inner wall causing edgefold or breakage
Solution Approach 1:
The paper shifting mechanism performs preliminary action by shifting the banknotes away from the paper outlet before the supporting plate moves to the receiving position. This prevents the banknotes from colliding with the inner wall during the plate's movement, thereby maintaining banknote integrity without requiring complex additional structures
Solution Approach 2:
The paper shifting mechanism acts as an intermediary between the supporting plate and the banknotes. It mediates the interaction by controlling the banknote position relative to the paper outlet, preventing direct harmful contact between the moving supporting plate and the banknotes during the receiving process
2Reliability
If the paper shifting mechanism shifts banknotes away from paper outlet, then edgefold and breakage are prevented, but the device complexity increases
Solution Approach 1:
The paper shifting mechanism is integrated into the existing apparatus structure, serving multiple functions: it shifts banknotes away from the paper outlet to prevent damage, and works in coordination with the supporting plate movement mechanism. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity
Solution Approach 2:
The paper shifting mechanism is merged with the existing supporting plate and separation mechanism structures. By combining functions and sharing structural elements, the patent achieves the banknote protection function without proportionally increasing overall device complexity
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 apparatus effectively prevents edgefold or breakage of banknotes by ensuring they are not collided with the inner wall during the receiving process, allowing for normal transportation and facilitating the operation of the cash recycling and handling apparatus.
Implementation Method 1
The separation mechanism includes a separating roller, a gate roller and a pickup roller
Implementation Method 2
the paper shifting mechanism is configured to drive the sheet medium to move into the storage cavity and away from the paper outlet
