Self-Adjusting Clamp Mechanism for Media Transport Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media item transport mechanisms in Self-Service Terminals (SSTs) face challenges in applying a suitable compression force, particularly when separating or adding items to a bunch, leading to operational failures during certain modes of operation.
Innovation Solution
A self-adjusting clamping mechanism that selectively applies a predetermined clamp force to media items based on their thickness, using a moveable clamp member and displacement sensors to maintain a consistent force during changes in the number of items, allowing for efficient transportation and separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compression force is applied to a bunch of media items during transportation, then slippage of media items is controlled, but the compression force is not suitable for separating media items from the bunch
Solution Approach 1:
The clamp member is made movable between a first position (applying compression force for transportation) and a second position (releasing or reduced compression force for separation). This dynamic adjustment allows the same clamping mechanism to adapt to different operational modes - maintaining grip during transport while allowing easy separation when needed, thus resolving the contradiction between transportation reliability and operational versatility
2Reliability
If a fixed clamp force is applied to media items, then transportation is reliable, but the system fails when media item thickness varies
Solution Approach 1:
A sensor detects the thickness of the bunch of media items and provides feedback to the control circuit. The control circuit then adjusts the clamp member's position or force accordingly. This feedback mechanism ensures that the clamp force is always appropriate for the current media item thickness, maintaining transportation reliability while preventing operational failures and maximizing productivity

AI summary
The present invention provides a method and apparatus for transporting items of media along a transport path. The apparatus comprises at least one clamp member to apply a clamp force to a bunch of media items located between a support surface and said clamp member, wherein said clamp member is selectively moveable towards or away from said support surface to apply a predetermined clamp force to the bunch of media items.
