Movable Dust Removal Device for Continuous Paper Printers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust removal systems in printers using continuous rolled paper face challenges in operability and convenience due to interference with the paper conveyance path and difficulty in cleaning, especially when the paper is rolled and in use.
Innovation Solution
A dust removal device with a movable dust removing member that can switch between a cleaning position for contact with the paper and a detachment position, allowing for efficient dust removal and easy cleaning without interfering with the paper conveyance, and enabling easier paper setup by removing the member from the path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dust removing unit is fixedly provided in the conveyance path to remove dust from continuous paper, then dust removal effectiveness is improved, but the rolled paper and dust removing unit interfere with each other during paper drawing, making paper setup difficult
Solution Approach 1:
The dust removing unit is made movable between a cleaning position (where it contacts the paper in the conveyance path) and a detachment position (where it is removed from the conveyance path). This dynamic configuration allows the unit to be present during printing for effective dust removal, yet removable during paper setup to avoid interference, thus resolving the contradiction between dust removal effectiveness and paper setup ease.
2Reliability
If the dust removing unit is fixedly attached to remove dust from the paper, then dust removal function is improved, but adjustment of the dust removing unit position becomes necessary after paper setting, reducing operability
Solution Approach 1:
The dust removing unit is designed to be movable along the conveyance path, allowing it to be positioned at different locations. This enables the unit to adapt to different paper widths and setup configurations without requiring complex adjustments, maintaining both effective dust removal and high operability.
3Reliability
If the dust removing unit is in contact with the rolled paper in the conveyance path, then dust removal is effective, but cleaning of the dust removing unit becomes difficult when paper exists in the path
Solution Approach 1:
The dust removing unit can be completely removed from the conveyance path by moving it to the detachment position. This extraction allows the unit to be cleaned separately without the obstruction of paper, making maintenance easy while still providing effective dust removal during printing operations.
4Manufacturing precision
If the dust removing unit is provided to clean dust from continuous paper, then printing quality is improved, but the unit interferes with paper drawing during setup, requiring additional adjustment time
Solution Approach 1:
The movable dust removing unit can be quickly positioned or removed from the conveyance path. During paper setup, the unit is in the detachment position to avoid interference, and during printing, it is in the cleaning position to ensure quality. This dynamic positioning reduces setup time while maintaining printing quality.

AI summary
A dust removal device for continuous paper improves operability and usability for a user. The continuous paper is continuously supplied in a rightward direction, then through guide rollers, the direction of the continuous paper is reversed leftward. A downward front surface of the continuous paper is cleaned with a first dust removal device. Further, a direction of the continuous paper is reversed with a guide roller rightward. A downward back surface of the continuous paper is cleaned with a second dust removal device, and is guided to the downstream side. The two dust removal devices are provided in a vertical positional relationship in space. Dust removed with a dust removing member falls to a dust receiving member and is stored in the dust receiving member. It is possible to easily dispose the dust by pulling out the dust removal device from a cleaning position to an outside detachment position.
