Bill Recycle Machine with Rotating Front Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing bill recycle machines in ATMs have a complex structure due to the need for an elevation plate and separate components like push and separating parts at the lower level, increasing the machine's volume and complexity.
Innovation Solution
A bill recycle machine design with a rotating front plate, a push plate, and a stack plate at the same level as the bill receiving space, eliminating the need for an elevation plate and simplifying the structure by using springs and solenoids to manage the movement of bills and components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an elevation plate is added to elevate the push plate and separating part to the lower level, then bills can be effectively separated and pushed, but the structure becomes more complex and the volume increases
Solution Approach 1:
The patent transitions from a vertical elevation approach (using an elevation plate to lift components to a lower level) to a horizontal arrangement approach. The push plate and separating part are positioned directly at the lower level of the bill receiving space, eliminating the need for vertical elevation mechanisms and reducing structural complexity while maintaining functional effectiveness.
Solution Approach 2:
The patent removes the elevation plate component entirely from the system. By extracting this unnecessary element, the design achieves simpler structure and reduced volume while still enabling effective bill separation and pushing through the direct horizontal arrangement of the push plate and separating part at the lower level.
2Device complexity
If the push plate and separating part are positioned at the lower level of the bill receiving space, then the structure is simplified, but the machine volume increases
Solution Approach 1:
The patent merges the push plate and separating part into a unified lower-level assembly that works together seamlessly. This integration allows both functions to be achieved within a compact footprint, reducing the overall machine volume while maintaining structural simplicity.
3Device complexity
If the push plate and separating part are positioned at the lower level, then the structure is simplified, but the bill handling effectiveness may be compromised
Solution Approach 1:
The patent employs a movable push plate that can dynamically adjust its position and apply force to the bills. This dynamic mechanism ensures effective bill pushing and separation at the lower level, maintaining reliable bill handling while preserving structural simplicity.
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
This design results in a simpler and more compact bill recycle machine structure, reducing the overall volume and complexity while maintaining effective bill separation and handling capabilities.
Implementation Method 1
a pickup roller installed at a position allowing the pickup roller to make contact with bills stacked in the first bill receiving space when the push plate moves frontward
Implementation Method 2
the front plate is locked by a solenoid when bills are deposited so as to prevent a separation part of a lower side of the front plate from being exposed
Implementation Method 3
the push plate and the stack plate are installed in such a manner as to be pulled by each spring in a direction of the transfer plate; the push plate is moved frontward by restoring force of a spring

AI summary
Disclosed is a bill recycle machine, in which a separation part for separating bills from each other and a push plate are installed at the same level as a bill receiving space, and an elevation plate is removed, so that a simple structure and small volume thereof can be achieve. The bill recycle machine includes: a front plate forming a wall surface of a front side of a bill receiving space formed at a lower part of a shutter, the front plate rotating about a hinge shaft of an upper part of the front plate; a push plate forming a first bill receiving space between the push plate and the front plate; a stack plate installed at an opposite side of the first bill receiving space, based on the push plate, so as to support bills stacked through a stack wheel; a transfer plate forming a second bill receiving space between the transfer plate and the stack plate; and a pickup roller installed at a position allowing the pickup roller to make contact with bills stacked in the first bill receiving space when the push plate moves frontward.
