ATM Media Separation Roller with Protruding Piece
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional media separation apparatuses in ATMs face issues with separating bundles of three or more media, leading to transfer errors and jams, as the separation belt only separates the lowermost medium, causing two or more media to be transferred together.
Innovation Solution
The media separation apparatus incorporates a feed roller with a guide groove and a separation roller featuring a media separation piece that protrudes to block the introduction of following media, preventing bundles from being separated together by overlapping the end portion of the media separation piece with the feed roller, thereby ensuring individual media separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separation belt is used to separate media, then the lowermost medium can be separated, but two or more media are transferred together causing transfer errors and jams
Solution Approach 1:
The separation roller is divided into multiple independent separation pieces (first separation piece, second separation piece, third separation piece) that can independently contact different media. Each separation piece acts as an independent separation unit, allowing the system to handle bundles of media more effectively by separating them one by one rather than attempting to separate the entire bundle at once.
Solution Approach 2:
The invention introduces a new spatial dimension by arranging separation pieces at different positions (upper, lower, and side positions) around the separation roller. This multi-dimensional arrangement allows separation pieces to contact media from multiple angles and positions, effectively preventing multiple media from being transferred together by blocking them at different spatial locations.
2Reliability
If multiple separation rollers are used to improve separation capability, then media bundles can be separated, but the device complexity increases
Solution Approach 1:
The separation roller serves multiple functions: it acts as both a separation element and a structural support for multiple separation pieces. The single separation roller integrates the functions of what would otherwise require multiple separate separation components, reducing overall device complexity while maintaining effective media separation capability.
Solution Approach 2:
Multiple separation pieces are merged onto a single separation roller, creating a unified separation mechanism. Instead of using separate rollers for each separation function, the invention combines multiple separation pieces on one roller, simplifying the mechanical structure while preserving the ability to handle media bundles effectively.
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 configuration effectively prevents the separation of media bundles, increasing media separation efficiency by ensuring each medium is separated individually and transferred correctly, reducing transfer path errors and jams.
Implementation Method 1
separates a following medium from a leading medium through friction of the separation belts
Implementation Method 2
the media separation piece blocks introduction of a following medium which is in close contact with the rear surface of a leading medium

AI summary
A media separation apparatus may include: a pickup roller disposed at one side of the loaded media, and configured to sequentially pick up and transfer the loaded media; a feed roller disposed separately from the pickup roller in a media feeding direction, and configured to feed the media picked up and transferred by the pickup roller toward a transfer path; and a media separator disposed at a position facing the feed roller, having a plurality of separation rollers and a separation belt wound around a part of the circumference of each of the separation rollers, and configured to separate a following medium from a leading medium through friction of the separation belt, the following medium being in close contact with the leading medium fed by the feed roller and transferred at the same time as the leading medium.
