Operation Knob Merging Drum and Conveyor Gears for Jam Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic transaction apparatuses, such as ATMs, face challenges in efficiently removing banknotes that have become jammed due to the need for a high-cost one-way clutch mechanism and the complexity of operating knobs, especially when temporary accumulating units require two-way conveying.
Innovation Solution
An automatic transaction apparatus is designed with an operation knob that can mesh with both the gear for rotating the conveying section and the gear for rotating the temporary accumulating unit, allowing both to be rotated simultaneously, simplifying the removal of jammed banknotes without the need for a one-way clutch mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate drive systems are used for the drum and conveying roller section, then the temporary accumulating unit can perform two-way conveying, but the operation becomes complex and time-consuming when removing jammed banknotes
Solution Approach 1:
The operation knob is designed to simultaneously mesh with both the drum gear and the conveying roller gear, merging the control of two separate drive systems into a single operation. This allows both the drum and conveying roller to rotate simultaneously when the knob is turned, simplifying the removal of jammed banknotes while maintaining two-way conveying capability.
Solution Approach 2:
The operation knob serves multiple functions: it can rotate the drum for accumulation, rotate the conveying roller for banknote transport, and simultaneously control both systems for jam removal. This multi-functionality eliminates the need for separate operations for each function, improving ease of operation.
2Ease of operation
If a one-way clutch mechanism is introduced to simplify operation, then the operation becomes easier, but the cost increases significantly
Solution Approach 1:
Instead of using a complex one-way clutch mechanism, the patent merges the control of two separate drive systems into a single operation knob that simultaneously meshes with both the drum gear and conveying roller gear. This achieves operational simplicity through direct mechanical coupling rather than through expensive one-way clutch components.
3Productivity
If both hands are used to rotate the drum and conveying roller section simultaneously, then the jammed banknote can be removed, but the operator cannot catch the removed banknote since both hands are full
Solution Approach 1:
The operation knob merges the rotation control of both the drum and conveying roller into a single hand operation. This allows the operator to remove jammed banknotes efficiently while maintaining hand availability to catch the removed banknote, as both systems are controlled by one hand rather than requiring two hands for separate operations.

AI summary
Disclosed is an automatic transaction apparatus 1 provided with a temporary accumulating unit that accumulates paper money temporarily and discharges them again, wherein jammed paper money can be discharged and removed easily with a simple construction. The automatic transaction apparatus 1, which is provided with the temporary accumulating unit 30 that accumulates paper money 7a temporarily by conveying the paper money 7a with a conveyor roller section 40 and winding them around a drum 60, and dispenses the temporarily accumulated paper money 7a from the drum 60 and discharges them from the conveyor roller section 40, was also provided with a manipulation knob 100 that is pushed-in between a gear 65 that rotates the drum 60 and a gear 47 that rotates the conveyor roller section 40, and intermeshed to the gears, enabling the knob to rotate both the gears simultaneously.
