Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sheet medium processing devices have complex structures, high costs, and limited adaptability to different types of mediums, often resulting in irregular alignment and output blockages due to the lack of a pressing device above the support plate.
Innovation Solution
A sheet medium processing device with a stacking mechanism comprising a lower and upper ticket stacking assembly, a first switching mechanism, and a retractable paper baffle, which allows for parallel movement and adjustment of the upper assembly relative to the lower assembly, enabling selective transport and stacking states, and includes elastic elements for maintaining medium flatness and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a traditional sheet medium processing device uses a simple support plate for stacking, then the device structure is simple, but the sheet mediums become irregularly aligned in the vertical direction when bent due to lack of pressing
Solution Approach 1:
The upper ticket stacking assembly is designed to move parallelly relative to the lower ticket stacking assembly, transitioning between transport position and stacking position. This dynamic configuration allows the device to adapt between different operational states, providing pressing capability during stacking while maintaining structural simplicity.
Solution Approach 2:
The elastic element acts as an intermediary between the upper and lower ticket stacking assemblies, providing pressing force to maintain sheet medium flatness and alignment. This elastic intermediary enables the upper assembly to exert controlled pressure on the sheet mediums without requiring a complex rigid pressing mechanism.
2Productivity
If the support plate outputs sheet mediums continuously, then productivity is high, but the output position is blocked easily causing processing interruptions
Solution Approach 1:
The device dynamically switches between transport state and stacking state through the movable upper ticket stacking assembly. During stacking state, the assembly positions sheet mediums for organized stacking; during transport state, it facilitates continuous output. This dynamic switching prevents output blockages while maintaining high productivity.
Solution Approach 2:
The ticket stacking assembly is divided into functionally independent upper and lower parts that can move relative to each other. The upper assembly can be positioned at transport position to clear the output path or at stacking position to organize sheet mediums, segmenting the functions to avoid blocking while maintaining continuous operation.
3Device complexity
If the device uses fixed stacking configuration, then the structure is simple, but the device cannot adapt to different types of sheet mediums
Solution Approach 1:
The upper ticket stacking assembly moves parallelly relative to the lower assembly, allowing the device to adapt between transport and stacking configurations. This dynamic adjustment enables the same device to handle different types of sheet mediums (cash, tickets, checks) by switching operational states rather than requiring multiple fixed configurations.
Solution Approach 2:
The movable upper ticket stacking assembly serves multiple functions: it acts as a pressing mechanism during stacking operations and as part of the transport mechanism during output operations. This multi-functionality allows a single device structure to adapt to different processing requirements for various sheet medium types.

AI summary
A sheet medium processing device comprising a stacking mechanism mounted on a frame, a first switching mechanism and a retractable paper baffle adjacent to the medium exit of the stacking mechanism; the stacking mechanism comprises a lower ticket stacking assembly, an upper ticket stacking assembly capable of moving parallelly above the lower ticket stacking assembly and a parallel movement confining mechanism, wherein the upper ticket stacking assembly and the lower ticket stacking assembly are both belt-conveyor mechanisms, and the belt of the upper ticket stacking assembly has a tendency of tightly pressing against the belt of the lower ticket stacking assembly. The first switching mechanism simultaneously controls the reciprocation of the paper baffle and the parallel movement of the upper ticket stacking assembly, enabling the stacking mechanism to be selectively provided with a transport state and a stacking state. The sheet medium processing device utilizes the elasticity of the belts of the stacking mechanism to adjust and limit the vertical-direction state of multiple stacked sheet mediums, thereby achieving reliable transportation.
