Bundle Module Guide Unit for Bill Collision Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medium deposit devices face issues with media disorder, residual errors, and jamming due to collisions when rejected bills are returned in bundles, leading to inefficiencies in the transfer path and increased errors as the number of stacked bills increases.
Innovation Solution
A bundle module with a transfer path, rotatably driven belts, and a guide unit that inclines to position the leading end of a following medium over the rear end of a leading medium, along with a medium sensing part and controller to manage the return process, preventing collisions and integrating the reject module's function within the bundle module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rejected bills are returned to the bundle module in units of bundles, then the reject module can store and return media efficiently, but the media become disordered, residual errors occur on the transfer path, and leading ends are not arranged properly
Solution Approach 1:
The reject module is divided into multiple sub-modules including a first transfer path for returning rejected bills, a second transfer path for arranging leading ends, and a stacking module. This segmentation allows different functional zones to handle specific tasks (returning vs. arranging) separately, resolving the contradiction between efficient bulk return and precise arrangement.
Solution Approach 2:
A second transfer path acts as an intermediary between the first transfer path and the stacking module. The second transfer path receives rejected bills from the first transfer path and performs the arrangement function there, mediating between the bulk return function and the precise stacking function to eliminate disorder and misalignment.
2Quantity of substance
If the number of stacked bills increases in the reject module, then more rejected media can be stored and returned, but residual errors and arrangement problems increase significantly
Solution Approach 1:
The transfer path is segmented into a first transfer path for bulk transport of rejected bills and a second transfer path for precise arrangement. This allows the system to handle large quantities in the first path while ensuring precision in the second path before stacking, resolving the contradiction between quantity and precision.
Solution Approach 2:
The second transfer path performs preliminary arrangement of leading ends before the bills are stacked. By arranging media in advance on the second transfer path, the system ensures proper alignment is achieved before the stacking operation, preventing arrangement problems even when large quantities are processed.
3Adaptability or versatility
If a separate reject module is provided between the discrimination unit and bundle module, then rejected bills can be stored and returned, but the device structure becomes complex and the transfer path becomes longer
Solution Approach 1:
The reject module is merged with the bundle module by integrating the rejection return function into the existing bundle module structure. The first and second transfer paths are incorporated into the bundle module's transfer system, eliminating the need for a completely separate reject module while maintaining reject bill handling capability.
Solution Approach 2:
The bundle module is designed with multi-functionality, serving both as a bundle input device and as a reject bill return destination. The transfer paths and stacking mechanism are configured to handle both normal bundle operations and rejected bill returns, reducing the need for dedicated separate components.
