Solution Overview
Problem
Existing bill processing apparatuses face challenges in reliably conveying and stacking bills of varying sizes and conditions, such as wrinkles, due to instability and skew during the conveyance process, which can lead to jamming and improper housing.
Innovation Solution
The apparatus incorporates a bill conveyance mechanism with conveyor belts and pulleys that adjust tension to ensure stable conveyance, combined with guide members and protrusions to correct inclination and ensure proper alignment, and a presser plate with a non-contact end face to prevent jamming, allowing for reliable housing of bills in the bill housing part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If bills are conveyed using a simple conveyance mechanism, then the device complexity is reduced, but the stability and reliability of bill conveyance deteriorates due to skew and jamming
Solution Approach 1:
The conveyance mechanism is divided into multiple independent conveyor members (first conveyor member and second conveyor member) that can be controlled separately. This segmentation allows each member to handle specific aspects of bill conveyance, improving overall reliability while maintaining manageable complexity through modular design.
Solution Approach 2:
The system dynamically adjusts the conveyance speed of individual conveyor members based on detected bill conditions (skew, wrinkles, size). By changing operational parameters like speed and tension independently for each conveyor member, the system achieves reliable conveyance of varied bills without requiring a completely complex mechanical structure.
2Manufacturing precision
If conveyor members are added to correct bill inclination and improve alignment, then the manufacturing precision of bill positioning is improved, but the device complexity increases
Solution Approach 1:
The conveyor members serve multiple functions: they convey bills forward, correct inclination through differential speed control, and maintain alignment throughout the conveyance path. This multi-functionality reduces the need for separate correction mechanisms, achieving high positioning precision without proportionally increasing device complexity.
Solution Approach 2:
The system employs dynamic speed adjustment of conveyor members based on real-time detection of bill conditions. The conveyor members can independently vary their speed to correct inclination and maintain alignment, providing adaptive positioning precision without requiring complex mechanical adjustment mechanisms.
3Adaptability or versatility
If the bill housing part is designed to accept various bill sizes and conditions, then the adaptability is improved, but the reliability of proper housing deteriorates due to jamming and improper stacking
Solution Approach 1:
The system incorporates detection means that continuously monitor bill conditions (size, skew, wrinkles) during conveyance and provide feedback to the control unit. This feedback enables real-time adjustment of conveyor member speeds and tensions, ensuring reliable housing of varied bill types by preventing jamming before it occurs.
Solution Approach 2:
The conveyor members perform preliminary correction of bill inclination and positioning before the bills reach the housing part. By pre-adjusting bill orientation and alignment during conveyance, the system ensures reliable stacking and housing of various bill types without requiring complex adjustment mechanisms in the housing itself.
