Pivotable Document Transport Path for Jam Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document processing apparatuses for value documents, such as banknotes, often experience jams due to dog ears, folds, or crumples, making it difficult to access and remove jammed documents from the transport path.
Innovation Solution
The apparatus features a pivotable movable part that can be easily swung open to access the transport path, allowing for easy removal of jams, with a modular design that includes a singler for separating documents and a transport system with driven elements to manage document flow without needing transmission to the stationary part, and a sensor arrangement for controlling document routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the apparatus uses a fixed enclosed transport path, then the document processing is protected and secure, but access to the transport path for removing jams becomes difficult
Solution Approach 1:
The movable part is designed to be pivotable between a closed position (forming the transport path) and an open position (providing access to the transport path). This dynamic configuration allows the apparatus to switch between protected operation mode and maintenance/access mode, resolving the contradiction between security and accessibility.
Solution Approach 2:
The apparatus is divided into a stationary part and a movable part that can be separated spatially. The movable part containing output pockets can be pivoted away from the stationary part, creating access to the transport path while maintaining the integrity of the processing system. This segmentation enables independent access without compromising the overall system protection.
2Ease of operation
If the apparatus includes a pivotable movable part for easy access, then jam removal becomes simple, but the device complexity increases
Solution Approach 1:
The pivotable movable part provides a simple mechanical solution for accessing the transport path. By using a single degree of freedom (pivoting motion), the design achieves easy access without requiring complex mechanisms, motors, or control systems that would increase device complexity.
Solution Approach 2:
Instead of making the entire apparatus movable or using complex disassembly mechanisms, the invention inverts the approach by having a fixed stationary part and a movable part that opens away from it. This inversion simplifies the overall structure while providing the needed access functionality.
3Device complexity
If the transport system uses driven elements contained in the movable part, then transmission to the stationary part is eliminated, but the movable part must bear additional mechanical load
Solution Approach 1:
The driven transport elements are merged with the movable part, eliminating the need for separate transmission mechanisms between stationary and movable parts. This consolidation simplifies the overall system architecture by integrating the drive function directly into the movable component.
Solution Approach 2:
The movable part serves multiple functions: it provides the output pockets for processed documents, enables access to the transport path when opened, and houses the driven transport elements. This multi-functionality reduces the need for additional components that would increase device complexity.
