Toner Supply Device with Multi-Container Selection and Feedback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed image forming apparatuses face issues with toner supply, leading to potential cessation due to insufficient toner, as conventional systems struggle to manage toner levels effectively across multiple containers, resulting in premature stoppages during high-speed printing operations.
Innovation Solution
A toner supply device with multiple containers, a feed device, and a controller that detects remaining toner quantities and selectively uses the container with the least amount of toner, ensuring continuous supply by adjusting the toner distribution based on consumption rates and using a partitioning member to optimize toner storage volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple toner containers are used in conventional systems, then toner supply capacity is increased, but toner management complexity increases and replacement timing cannot be optimized
Solution Approach 1:
The controller receives feedback from remaining toner quantity detectors in each container, continuously monitoring toner levels. Based on this feedback, the controller automatically selects which container to use and controls the feed device to supply toner from the appropriate container, optimizing replacement timing and managing multiple containers efficiently.
Solution Approach 2:
The system performs preliminary detection of remaining toner quantities in all containers before making selection decisions. The controller pre-plans which container to use based on detected toner levels, ensuring that toner supply is maintained without interruption and replacement timing is optimized before toner actually runs out.
2Productivity
If high-speed printing is continuously performed with a second toner container, then printing productivity is maintained, but the time up to replacement becomes short causing potential stoppages
Solution Approach 1:
The controller detects remaining toner quantities in advance and performs preliminary selection of which container to use. By planning ahead based on detected toner levels, the system ensures that when one container is depleted, another container with sufficient toner is already ready, maintaining continuous high-speed printing without interruption or premature stoppages.
Solution Approach 2:
The system continuously monitors remaining toner quantities and uses this feedback to dynamically adjust container selection. This feedback mechanism ensures that the system can maintain high-speed printing productivity while optimizing replacement timing, switching to appropriate containers before toner depletion occurs.
3Device complexity
If conventional toner supply systems are used, then simple structure is maintained, but toner empty detection is delayed causing apparatus stoppages
Solution Approach 1:
Remaining toner quantity detectors provide continuous feedback on toner levels in each container. The controller uses this feedback to proactively manage toner supply, selecting appropriate containers before toner is depleted. This feedback mechanism prevents delayed detection and ensures continuous reliable operation without apparatus stoppages.
Solution Approach 2:
The system performs preliminary detection and selection actions before toner depletion occurs. By detecting remaining quantities in advance and pre-selecting which container to use, the system maintains simple structure while improving reliability, preventing toner empty stoppages through proactive management.
