Sheet Processing Device Temporary ID Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sheet processing systems experience a significant decrease in processing efficiency when information cannot be read from the header card, leading to unnecessary transportation and re-processing of banknotes.
Innovation Solution
A sheet processing apparatus with a recognition unit that generates temporary identification information when the header card information cannot be read, allowing continuous processing without efficiency loss, using a banknote inlet unit, transport unit, and a controller to associate recognition results with temporary identification for uninterrupted banknote processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sheet processing system uses header cards with bar codes for identification, then the system can track and sort banknote bundles, but when the bar code information cannot be read, the banknotes must be transported twice inside the apparatus, causing processing efficiency to decrease seriously
Solution Approach 1:
The system performs preliminary recognition of the header card using the first recognition unit during the initial transport phase. This preliminary action allows the system to identify header cards before final processing decisions are made, enabling efficient handling even when subsequent recognition attempts fail.
Solution Approach 2:
The controller acts as an intermediary that manages the recognition process between the first and second recognition units. When the second recognition unit fails to read the bar code, the controller intervenes to retrieve the previously recognized information from memory and continues processing, preventing the need for re-transport and maintaining productivity.
2Reliability
If the system retrieves and re-processes banknotes when header card information is unreadable, then complete processing can be achieved, but the processing time increases and efficiency decreases
Solution Approach 1:
The system creates a copy of the header card information in the controller's memory during the initial recognition phase. When the original bar code cannot be read later, the system uses this copied information to continue processing without needing to retrieve and re-process the physical banknotes, thereby reducing processing time while maintaining completeness.
Solution Approach 2:
The system maintains continuous processing by storing recognized header card information in memory and using it to proceed with banknote processing even when subsequent recognition attempts fail. This continuity prevents interruptions and re-processing cycles, minimizing time loss while ensuring complete and accurate processing.

AI summary
Provided is a sheet processing apparatus which enables processing of a sheet without a decrease in processing efficiency even when the phenomenon that the information cannot be read from the header card arises. The sheet processing apparatus is a sheet processing apparatus that successively processes a plurality of processing-target sheets forming a sheet group, the sheet group including at least one sheet set, the at least one sheet set including a first sheet that is given first recognition information and a second sheet, the sheet processing apparatus includes a recognition unit that reads the first recognition information from one of the plurality of processing-target sheets and a controller that generates second recognition information associated with the one of the plurality of processing-target sheets when the recognition unit fails to read the first recognition information from the one of the plurality of processing-target sheets and a predetermined condition is satisfied.
