Media Separation Belt Power Transmission With Swing Clutch Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional media deposit machines face issues with power transmission failure due to the swing gear and pickup pulley gear engagement being maintained in an on-state without smoothly switching to an off-state, leading to inefficient media conveyance.
Innovation Solution
A power transmission structure with a swing arm and clutch gear system that allows the swing gear to intermittently couple or release from the clutch gear, enabling smooth power transmission direction switching based on the media conveying direction, using a motor, relay gears, and one-way bearings to transmit driving force to either the feed or pickup pulley.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the swing gear and gear connected to the pickup pulley are strongly engaged with each other in the on-state, then power transmission is maintained, but the swing gear cannot smoothly switch to the off-state and power transmission fails
Solution Approach 1:
A clutch gear is introduced as an intermediary component between the swing gear and the pickup pulley gear. The clutch gear includes a clutch arm that can be coupled to or separated from the swing gear, acting as a mediator that enables smooth transition between engaged and disengaged states. This intermediary mechanism allows the swing gear to be strongly engaged when needed while providing a smooth switching path to the off-state through the clutch arm's coupling and separation actions.
2Adaptability or versatility
If the pickup pulley height is changed to adapt to media thickness, then media handling flexibility is improved, but power transmission stability is affected
Solution Approach 1:
The system employs dynamic adjustment mechanisms where the pickup pulley height can be changed according to media thickness requirements. The clutch gear and swing arm mechanism dynamically adapts to these height changes, maintaining reliable power transmission regardless of the pickup pulley's vertical position. The clutch arm can be coupled or separated based on the required media conveying direction, ensuring stable power transmission while accommodating the dynamic height adjustments needed for different media handling scenarios.

AI summary
One embodiment provides a power transmission structure of a media separation unit, the power transmission structure including a pickup pulley and a feed pulley that are provided at positions spaced apart at both sides; a media separation belt configured to travel along the pickup pulley and the feed pulley, grip and convey media, and have a slope that changes due to contact with a bill press configured to support the media and move upward or downward at a lower side of the pickup pulley; a motor configured to provide a driving force for the media separation belt to rotate in one direction or the other direction; at least one relay gear configured to transmit the driving force of the motor; a swing arm configured to swing in both direction within a predetermined angle range in conjunction with rotation of the relay gear; a swing gear configured to be connected to the swing arm and rotate in conjunction with the rotation of the relay gear to transmit power for the swing arm to swing; and a clutch gear configured to intermittently be coupled to or released from the swing gear according to a swing direction of the swing arm and configured to transmit power to the pickup pulley through a connection belt, whose slope changes in conjunction with a change in the slope of the media separation belt.
