Item Stacking Roller Mechanism for ATM Media Buckling Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stacking bins in ATMs and similar terminals face issues with items colliding and buckling, leading to reduced storage capacity and increased sorting time, especially in vertical bins where gravity causes items to drop and lose order, resulting in jams and service downtime.
Innovation Solution
The apparatus employs a rotatable roller element with flexible paddles and flaps to locate incoming items at a desired position, pinching them in place while keeping preceding items out of the way, using a combination of flexible paddles and flaps supported on the roller to rotate and guide items into a stack position without collision, thus preventing buckling and maintaining order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If items are driven through a paper transport system using pairs of rollers that pinch the items and rotate to drive the items along a pre-determined pathway, then items can be transported to a stacking bin, but the lead edge of an incoming item can collide with the trailing edge of items already in the stack, causing buckling and folding
Solution Approach 1:
A tail engaging element is introduced as an intermediary component between the incoming item and the existing stack. This element engages with the trailing edge of the incoming item and urges it toward the stack position, acting as a mediator that prevents direct collision between the incoming item's lead edge and the existing stack, thereby resolving the buckling problem while maintaining transport efficiency
Solution Approach 2:
The tail engaging element performs preliminary action by engaging with the trailing edge of the incoming item before the item reaches the stack position. This preliminary engagement guides the item into the correct position and prevents collision before it occurs, ensuring stacking integrity without compromising transport speed
2Quantity of substance
If a vertical stacking bin is used where introduced items of media are inclined to drop to the bottom of the bin with the assistance of gravity, then storage capacity is improved, but the order in which incoming items of media are received is lost when buckled and/or folded items collide
Solution Approach 1:
The tail engaging element serves as a mediator that maintains item order by guiding each incoming item into the stack in sequence. By engaging with the trailing edge and urging it toward the stack position, it prevents buckling and collision that would cause items to lose their received order, while still allowing the vertical bin to achieve high storage capacity through gravity-assisted dropping
3Ease of operation
If standard rollers are used to drive items into the stack, then items can be moved along the transport pathway, but items may collide and buckle, making them difficult to retrieve and reducing storage capacity
Solution Approach 1:
The tail engaging element introduces local quality by providing specialized engagement at the trailing edge of items, rather than using uniform roller contact throughout. This localized engagement at the tail end prevents buckling and maintains item neatness, making retrieval easier while maximizing effective storage volume by preventing disorderly stacking
