Reject Transport Device for Automated Value Document Rerun
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing value document processing systems require significant manual effort for reworking reject documents due to inefficiencies in re-checking and re-assignment, with risks of incorrect assignment and increased operational complexity.
Innovation Solution
The system employs reject transport units with individual machine-readable identifiers for automatic re-routing and re-checking of reject documents, allowing for fully automated re-assignment and re-processing without operator intervention, reducing manual reworking and improving throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reject value documents are manually reworked at a manual reworking station, then the checking can be completed, but the manual effort required is great
Solution Approach 1:
The system enables reject value documents to re-check themselves automatically through the rerun process. The documents are automatically returned to the input pocket, re-singled, and re-checked by the same apparatus without manual intervention, allowing the system to service itself and reduce dependency on manual reworking stations.
Solution Approach 2:
The patent replaces the manual mechanical reworking process with an automated system. Instead of manual handling at a reworking station, the system uses automated transport means to return reject documents to the input pocket and automated re-processing through the singling and checking devices, substituting mechanical automation for manual labor.
2Loss of information
If separation cards are used to separate reject value documents of different input stacks, then the documents can be re-assigned after rerun, but additional effort and risk of incorrect assignment increase
Solution Approach 1:
The patent extracts and removes the separation cards from the system entirely. Instead of using physical separation cards to mark and track reject documents from different input stacks, the system processes documents without these intermediary elements, eliminating the associated complexity and potential for errors in card management and assignment.
Solution Approach 2:
The patent eliminates the need for separation cards as intermediaries by implementing a direct automated tracking and re-assignment system. The control device manages the re-processing workflow without requiring physical mediators like separation cards, reducing complexity while maintaining assignment accuracy through automated control.
3Reliability
If the stack of reject value documents is turned over for rerun, then the correct assignment to input packets can be achieved, but additional processing steps are required
Solution Approach 1:
The patent inverts the traditional approach by automatically returning reject documents to the input pocket for rerun, rather than manually retrieving and re-processing them. This inversion of the workflow - having the system bring documents back to input rather than taking them out for manual handling - maintains assignment correctness while improving throughput by eliminating manual steps.
4Extent of automation
If reject value documents are automatically returned to the input pocket for rerun, then manual reworking is reduced, but the system complexity increases
Solution Approach 1:
The patent implements a universal return transport system that can handle reject documents from any input pocket and return them to the appropriate input for rerun. This multi-functional transport mechanism serves multiple purposes: automatic return, re-assignment, and re-processing, reducing the need for separate dedicated systems for each function and thereby managing complexity while maintaining high automation.

AI summary
Input stacks of value documents are inserted in an input pocket of the value document processing apparatus, transported through the apparatus, checked and sorted into different deposit pockets of the value document processing apparatus, wherein reject value documents are deposited separately from the valid value documents. The reject value documents are automatically transported back to the input pocket with the aid of a reject transport device, to check the reject value documents again with the same value document processing apparatus (rerun). The reject transport device has several reject transport units, in which the reject value documents from the different input stacks are deposited separately from each other, and a reader for reading in the machine-readable identifier of the respective reject transport unit used for assigning the reject value documents of the respective reject transport unit to the input stack to which these reject value documents belong.
