Tape Removal Apparatus Using Vacuum Rollers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for preparing cassette spools with tape material on new backing paper often result in loss of tacking ability, alignment issues, poor adhesion, tension problems, and increased costs due to the need for multiple machines and excessive time, leading to inefficiencies and wrinkles in the laminate.
Innovation Solution
A method and apparatus that unrolls tape material from original backing paper, cuts it into portions, uses a bending member to separate the tape from the paper, and employs vacuum rollers to transfer the tape to rollers, eliminating the need for new backing paper by cutting and rolling the tape around vacuum rollers to remove it from the original backing paper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If tape material is transferred to new backing paper, then tape can be prepared for use, but tacking ability is lost and adhesion is poor
Solution Approach 1:
The invention extracts the tape material from the original backing paper directly at the point of use, eliminating the intermediate transfer step to new backing paper. The tape is cut from the continuous roll while still attached to the original backing paper, and then directly applied to the working surface, preserving its tacking ability and adhesion properties without degradation from transfer operations.
Solution Approach 2:
The invention uses the original backing paper as an intermediary carrier that maintains the tape's adhesive properties throughout the process. Instead of transferring tape to new backing paper which degrades performance, the original backing paper serves as a stable intermediary that allows direct application to the working surface, eliminating the harmful intermediate transfer step.
2Ease of manufacture
If tape material is transferred to new backing paper, then tape can be prepared, but alignment is poor and wrinkles are formed
Solution Approach 1:
The invention extracts the tape material directly from the continuous roll at the precise moment of application, eliminating the intermediate transfer step that causes misalignment and wrinkles. The tape is cut and applied in a single continuous operation, ensuring perfect alignment and a wrinkle-free surface without the disturbances introduced by transfer to new backing paper.
Solution Approach 2:
The invention performs the cutting and application operations in advance while the tape is still on the continuous roll, before any potential misalignment or wrinkle formation can occur during transfer. The tape is prepared and applied in a predetermined sequence that prevents deformation, ensuring manufacturing precision is maintained throughout the process.
3Ease of manufacture
If multiple machines are used for tape transfer, then tape can be prepared, but costs increase and time is excessive
Solution Approach 1:
The invention merges multiple separate operations (unrolling, cutting, transferring, applying) into a single integrated process. The tape is unrolled, cut, and applied to the working surface in one continuous operation using a single apparatus, eliminating the need for multiple machines and sequential operations, thereby reducing time and costs while maintaining manufacturing capability.
Solution Approach 2:
The invention employs a multi-functional apparatus that performs unrolling, cutting, and application functions within a single device. This universal machine replaces multiple specialized machines, reducing overall system complexity, cost, and operation time while maintaining the ability to prepare and apply tape material effectively.

Function Achieved in This Case
This approach reduces the need for new backing paper, decreases costs, minimizes wrinkling and tension, improves adhesion, and enhances efficiency by simplifying the process, reducing machine requirements, and preventing tape lifting from the working surface.
Implementation Method 1
