Banknote Separation Apparatus with Adjustable Pickup Roller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated teller machines face challenges in efficiently processing banknote bundles due to separate apparatuses for bills and checks, leading to increased size and issues with banknotes getting caught during dispensing, especially when dealing with varying check sizes and bundles.
Innovation Solution
A banknote separation apparatus for a bundle receiving machine that includes a guide unit, a pickup roller unit, a pickup roller raising/lowering unit, a feeding roller unit, and a gate roller unit, allowing for adjustable pickup roller height and automatic separation of banknotes from bundles, enabling efficient processing of both bills and checks in various sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate apparatuses are provided for receiving and dispensing bills and checks, then the machine can process different types of banknotes, but the overall size of the automated teller machine is increased
Solution Approach 1:
The patent combines the bill receiving/dispensing apparatus and check receiving/dispensing apparatus into a single integrated banknote bundle receiving/dispensing machine. Both apparatuses share common components including the housing, control unit, and feeding mechanism, allowing the machine to process both bills and checks without requiring separate dedicated devices for each type.
Solution Approach 2:
The machine is designed with universal functionality to handle both bills and checks through a single apparatus. The feeding unit and separation mechanism are configured to accommodate different types of banknotes, and the guide units can be adjusted to suit various banknote dimensions, enabling one machine to perform multiple functions that previously required separate devices.
2Adaptability or versatility
If the machine is designed to handle checks of different sizes, then it can be used in countries with varying check standards, but the feeding mechanism becomes more complex
Solution Approach 1:
The guide units are designed to be adjustable rather than fixed, allowing their positions to be dynamically changed according to the size of the banknotes being processed. This dynamic adjustment capability enables the machine to accommodate different check sizes without requiring multiple fixed configurations or complex interchangeable components.
Solution Approach 2:
The machine allows adjustment of geometric parameters of the guide units and feeding mechanism to match different banknote dimensions. By changing parameters such as guide unit spacing, feeding roller positions, and separation distances, the system can adapt to various check sizes while maintaining a relatively simple overall structure.
3Productivity
If multiple banknotes are fed simultaneously in a bundle, then processing efficiency is improved, but the banknotes may be caught in the feeding unit causing delays
Solution Approach 1:
The feeding process is segmented into multiple stages: first, the banknote bundle is fed as a group to maintain high productivity; then, the separation unit divides the bundle into individual banknotes one by one. This segmentation allows the system to benefit from both bundle feeding efficiency and individual processing reliability, preventing jams that occur when multiple banknotes are forced through a single feeding point simultaneously.
Solution Approach 2:
A guide unit is introduced as an intermediary component between the feeding unit and the separation mechanism. This guide unit properly positions and aligns the banknote bundle during feeding, ensuring smooth transition to the separation stage and preventing banknotes from getting caught or misaligned in the feeding unit, thereby maintaining both speed and reliability.
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 allows for efficient and space-saving processing of banknote bundles by automatically adjusting the pickup roller to prevent jamming and accommodate different banknote sizes, ensuring smooth operation and reduced machine size for use in multiple countries.
Implementation Method 1
a pickup roller unit provided above the guide unit in a spaced-apart relationship with the guide unit and configured to separate a banknote from the banknote bundle and to feed the banknote
