ATM Stack Transporter Rotation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated banking machines face challenges in efficiently handling financial instrument sheets with varying properties, require enhanced security, and need improved weather resistance and service access while minimizing unauthorized access.
Innovation Solution
An automated banking machine with a user interface, cash acceptor mechanism that separates individual sheets from a stack using a picking member and stripper portions, and a housing design that includes a secure chest with a cash acceptor mechanism positioned outside the secure area to minimize risk of unauthorized access, along with features like a water capturing system and resilient gasket for weather resistance and service access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cash acceptor mechanism is positioned inside the secure chest area, then security is improved, but service access and maintenance become more difficult
Solution Approach 1:
The cash acceptor mechanism is separated from the secure chest area and positioned in an accessible location outside the secure enclosure. This segmentation allows the acceptor mechanism to be serviced independently without compromising the security of the chest area, resolving the contradiction between security and service accessibility.
2Ease of operation
If openings in the machine are made larger to facilitate sheet insertion and removal, then ease of operation is improved, but weather resistance deteriorates
Solution Approach 1:
A flexible gasket is installed around the sheet opening to create a weather-sealed barrier. The gasket maintains flexibility to allow large opening movements for easy sheet insertion and removal, while simultaneously providing a tight seal against rain and snow when the opening is closed, resolving the contradiction between operational ease and weather resistance.
3Productivity
If mechanisms are designed to handle sheets rapidly, then productivity is improved, but reliability deteriorates due to increased risk of sheet damage
Solution Approach 1:
The sheet separation mechanism uses dynamic, adjustable picking members that can adapt their engagement force and position based on sheet properties. This allows the mechanism to handle sheets rapidly while maintaining appropriate force levels to prevent damage, resolving the contradiction between productivity and reliability.

AI summary
An ATM can accept a bulk stack of currency notes for deposit from a customer. The ATM includes a stack transporter (400) that can rotate an accepted stack while relocating it to a predetermined location inside of the machine. The stack transporter includes a rotatable housing (406) in which a stack holder (404) is movable. The stack holder can receive a currency stack (411) deposited in a fascia opening (412) by a customer. The stack holder is retracted to move the stack away from the opening and into the housing to completely move the stack into the machine. The housing, having the bulk stack therein, is then rotated to move the stack away from the opening and toward a stack processing area in the machine. The stack holder is then extended to expose a stack end out of the housing for stack processing.
