Inkjet Cleaning Roller Adaptive Drive Mode Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inkjet recording apparatuses face a challenge in maintaining high ink removal efficiency while ensuring cleaning roller durability, particularly when dealing with varying conveyance speeds and ink deposition levels, as existing mechanisms either compromise on efficiency or durability.
Innovation Solution
The apparatus incorporates a cleaning roller that can be driven either by the conveyance belt or independently, with a controller selecting the mode based on detected parameters such as conveyance speed, recording medium width, and ink amounts, allowing for adaptive operation to optimize both ink removal efficiency and roller durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the cleaning roller is driven by the conveyance belt, then roller durability is improved, but ink removal efficiency decreases when conveyance speed increases
Solution Approach 1:
The cleaning roller's drive mode is made dynamic and adjustable. The controller switches between conveyance-belt-driven mode (for durability) and independent motor-driven mode (for high-speed ink removal) based on real-time detection of conveyance speed and ink deposition conditions, allowing the system to adapt to varying operational requirements
Solution Approach 2:
The system changes the operational parameters of the cleaning roller by switching drive modes. When conveyance speed exceeds a threshold or ink deposition is detected, the controller changes the cleaning roller's drive parameter from being belt-driven to motor-driven, optimizing performance for specific conditions
2Productivity
If the cleaning roller is driven independently, then ink removal efficiency is maintained at high levels, but roller durability decreases due to rubbing against the conveyance belt
Solution Approach 1:
The cleaning roller's drive mode is made dynamic and adjustable. The controller switches between conveyance-belt-driven mode (for durability) and independent motor-driven mode (for high-speed ink removal) based on real-time detection of conveyance speed and ink deposition conditions, allowing the system to adapt to varying operational requirements
Solution Approach 2:
The system uses feedback from speed detectors and ink deposition detection to control the cleaning roller's drive mode. When the conveyance belt speed is low or ink is detected on the belt, the controller activates independent motor drive to maximize cleaning efficiency; otherwise, it uses belt drive for durability

AI summary
An inkjet recording apparatus comprising: a conveyance belt for conveying a recording medium; a cleaning roller kept in contact with the conveyance belt to clean the conveyance belt; and a controller for controlling the cleaning roller so as to be able to select between two modes for its driving, wherein the two modes are the mode in which the cleaning roller is driven by the movement of the conveyance belt and the mode in which the cleaning roller is driven independently of the movement of the conveyance belt.
