Modular Stacker With Reversible Motor Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document handling systems, such as automated teller machines and bill storage devices, are cumbersome due to their large size and complex structures, and often lack the ability to easily remove and maintain components like cashboxes and stackers, which complicates document management and maintenance.
Innovation Solution
A document handler comprising a validator and a removably attached stacker with a storage system, where the stacker is driven by a reversible motor and features a deflection lever system for guiding documents, allowing for easy attachment and detachment for maintenance and management, and eliminating the need for a separate drive source, thus reducing weight and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bidirectional path with unidirectional paths is used to connect cashboxes and reject safe, then document transport functionality is achieved, but the structure becomes complicated and size increases
Solution Approach 1:
The patent divides the document handling system into modular components: a validator unit and a stacker unit with storage. Each unit has its own conveyor system, eliminating the need for complex bidirectional paths connecting multiple cashboxes and reject safes. The segmentation allows independent operation and simplifies the overall structure while maintaining transport functionality.
Solution Approach 2:
The stacker with storage is designed as a detachable module that can be removed from the validator. This extraction principle eliminates the need for permanent complex connections between components, allowing the storage unit to be taken out for bill collection without affecting the validator's operation, thus simplifying the overall system structure.
2Stability of the object's composition
If cashboxes and reject safe are permanently integrated into the machine, then structural stability is maintained, but removal for bill collection becomes inconvenient
Solution Approach 1:
The connection between the stacker and validator is designed to be dynamic rather than static. The stacker can be attached when needed for operation and detached when bill collection is required. This dynamic design allows the system to switch between stable integrated operation and convenient separable maintenance, resolving the contradiction between structural stability and ease of operation.
3Adaptability or versatility
If a separate drive source is provided for the stacker, then operational independence is achieved, but weight and device complexity increase
Solution Approach 1:
The drive mechanism for the stacker's conveyor is merged with the validator's existing drive system. When the stacker is attached to the validator, they share a common drive source through the main conveyor. This merging eliminates the need for a separate drive motor in the stacker, reducing weight while maintaining operational independence through controlled engagement of the drive connection.
