Tape Cleaning Structure Vacuum Suction Dust Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tape devices struggle to maintain a high level of cleanliness on both the tape surface and edges, leading to servo signal dropouts and read errors due to dust accumulation, with existing cleaning structures being inefficient and labor-intensive.
Innovation Solution
A tape device with a cleaning structure featuring a guiding member with a sliding surface and vacuum supply for dust removal on the tape surface, combined with a guiding wall to address dust on the tape edges, ensuring thorough cleaning and compact installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a cleaning tape is used to remove dust from the tape surface, then dust removal is achieved, but the cleaning structure occupies large space and cannot effectively clean tape edges
Solution Approach 1:
The cleaning structure is divided into multiple independent components: a cleaning blade for scraping dust and a vacuum suction device for removing dust particles. This segmentation allows each component to perform its specific function efficiently while reducing the overall space requirement compared to a single large cleaning tape mechanism.
Solution Approach 2:
The cleaning structure is designed to simultaneously clean both the tape surface and tape edges using the combination of the cleaning blade and vacuum suction. This multi-functional approach eliminates the need for separate cleaning mechanisms for different tape areas, thereby reducing the total space occupied by the cleaning system.
2Object-affected harmful factors
If a blade is used to scrape dust from the tape surface, then dust is removed, but dust accumulates at the leading end of the blade requiring separate removal
Solution Approach 1:
The cleaning blade and vacuum suction device are merged into a single integrated cleaning structure. The vacuum suction device is positioned to immediately suction dust particles as they are scraped off by the cleaning blade, preventing dust accumulation at the blade's leading end. This combination eliminates the need for separate dust removal operations and reduces maintenance time.
3Reliability
If conventional cleaning structures are used, then dust on tape surface is partially removed, but dust on tape edges is not effectively cleaned leading to servo signal dropouts
Solution Approach 1:
The cleaning structure is designed with different components targeting different areas of the tape: the cleaning blade is positioned to scrape the tape surface, while the vacuum suction device is configured to suction dust from both the tape surface and the tape edges. This localized cleaning approach ensures that dust on tape edges, which causes servo signal dropouts, is effectively removed.

AI summary
A cleaning structure for removing dust is constituted of a guiding member having a sliding surface for guiding run of a tape, and a vacuum pressure supply source for making a vacuum pressure effect on a suction space provided inside the guiding member and so on. At the sliding surface of the guiding member, a suction port for making the suction space communicate with an external space is formed, and the opening edge of the suction port on the downstream side in the tape running direction is served as a first dust removal portion for removing dust on the tape surface. The guiding member has a guiding wall having a contact surface which guides at least one tape edge of a tape, and the contact surface is served as a second dust removal portion for removing dust adhering to the tape edge.
