Banknote Pressing Mechanism for Compact Sorting Bundling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sorting-bundling integrated apparatuses require a linear pressing mechanism that occupies significant space and interferes with other functional modules, making it difficult to implement effectively.
Innovation Solution
A banknote stacking and tidying module with a vertical reciprocating pressing mechanism using a cam, pressing rod, and torsion spring, which eliminates the need for a linear pressing mechanism along the thickness direction, allowing for compact arrangement and efficient banknote pressing and conveying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a linear pressing mechanism is installed along the thickness direction of sheet media, then the pressing function is achieved, but the mechanism takes up much space and cannot be hidden into other functional sub-modules completely
Solution Approach 1:
The pressing mechanism is transformed from a linear arrangement along the thickness direction to a rotational arrangement in the horizontal plane. The cam rotates about a vertical axis, and the pressing rod moves horizontally to apply pressing force, changing the dimension of the pressing action from vertical to horizontal, thus saving vertical space and enabling compact integration.
Solution Approach 2:
The pressing mechanism is integrated within the banknote stacking module structure. The cam and pressing rod are positioned such that the pressing action occurs within the existing module footprint, allowing the pressing function to be nested within the stacking module without requiring separate dedicated space.
2Device complexity
If a linear pressing mechanism is installed along the thickness direction of sheet media, then the pressing function is achieved, but it cannot be hidden into other functional sub-modules completely and may affect the operation of other functional modules
Solution Approach 1:
By changing the pressing direction from vertical to horizontal, the mechanism fits within the horizontal plane of the stacking module, allowing better spatial integration with other functional modules operating in the vertical dimension, thus reducing interference.
Solution Approach 2:
The pressing mechanism is merged with the banknote stacking module, where the cam and pressing rod are integrated into the module's structural framework. The pressing rod is positioned to work in coordination with the stacking plates, combining the pressing function with the existing stacking operation without requiring separate module space.
3Volume of moving object
If a cam mechanism is used for pressing banknotes, then the space occupation is reduced, but the mechanism complexity increases
Solution Approach 1:
The cam mechanism serves multiple functions: it converts rotational motion to reciprocating motion, provides the pressing force through its profile, and automatically times the pressing action within the stacking cycle. This multi-functionality reduces the need for separate actuators and control mechanisms, offsetting the inherent cam complexity with functional consolidation.
Solution Approach 2:
The cam mechanism is self-actuating through the rotation of the cam drive shaft, which is driven by the module's existing drive system. The pressing rod automatically reciprocates as the cam rotates, eliminating the need for separate motors or actuators for the pressing action, thus reducing overall system complexity despite the cam's mechanical 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 solution saves space by eliminating the need for a linear pressing mechanism, reducing the equipment's volume, and enables effective banknote pressing and conveying without affecting other functional modules' operations.
Implementation Method 1
the cam is cooperated with the driving end of the pressing rod to drive the pressing rod to rotate about the second rotating shaft between a release position and a pressing position
Implementation Method 2
one end of the pressing spring is fixed on the bracket, and the other end of the pressing spring is connected to the pressing end of the pressing rod for applying an elastic force to the pressing rod to press banknotes tightly
