Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filing strip machines face issues with waste generation, user-friendly operation, and precision in applying filing strips to sheet materials due to the limitations of cover tape unwinding and feeding mechanisms, which lead to inefficiencies and potential device malfunctions.
Innovation Solution
A roll-off tape with equidistant perforations for engaging a spiked roller and distinct markings for authentication and type determination by a sensor, allowing for automatic recognition and precise feeding of filing strips, enabling waste-free and versatile application across different formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover tape is wound up to feed the filing strip, then the filing strip can be transported, but the feed precision deteriorates due to increasing windup diameter and elastic deformation
Solution Approach 1:
The patent replaces the mechanical cover tape unwinding system with an optical detection system. The sensor detects markings on the filing strip to determine its type and position, eliminating reliance on mechanical feed precision. The control unit processes optical signals to control the application device, substituting mechanical positioning with electronic control based on optical feedback.
Solution Approach 2:
The patent implements a feedback mechanism where a sensor continuously detects markings on the filing strip and transmits information to the control unit. The control unit adjusts the application device based on this feedback, enabling precise positioning despite variations in feed mechanism performance. This closed-loop control compensates for the imprecision inherent in cover tape unwinding.
2Object-affected harmful factors
If the masking tape is used to cover the adhesive film, then the adhesive is protected, but the tape breaks easily causing device malfunction
Solution Approach 1:
The patent changes the material parameter of the protective layer from thin masking tape to a more robust structure. The protective tape is designed with greater tensile strength and dimensional stability, changing its physical parameters to resist breaking during the unwinding and feeding process while maintaining its protective function.
Solution Approach 2:
The patent applies a protective tape that is specifically designed to withstand the mechanical stresses of the feeding process. This beforehand cushioning ensures that the adhesive film remains protected throughout the entire operation, preventing premature exposure or damage that would cause device malfunction.
3Object-generated harmful factors
If the cover tape surface is made slippery to prevent adhesive transfer, then adhesive contamination is reduced, but the tape cannot be rewound properly
Solution Approach 1:
The patent segments the functional requirements: the protective tape surface is designed with low adhesive transfer properties to prevent contamination, while the rewind function is achieved through the tape's structural design and tension control mechanism rather than surface friction. The separation of these functions allows each to be optimized independently.
4Productivity
If the filing strip is fed by unwinding cover tape, then the strip can be transported, but waste is generated that requires manual removal
Solution Approach 1:
The sensor detects the position and type of filing strip by reading markings on the strip itself. This feedback information is sent to the control unit, which precisely controls the application device to apply only the required portion of the filing strip. This eliminates the need for manual cutting and removal of excess tape, converting a manual waste-removal process into an automated precise application process.

AI summary
The present invention relates to a semi-finished product, more precisely a conveyor belt for separating sheets into binding strips, comprising at least two binding holes and/or a centrally arranged slot along the direction of travel for guiding a band, equidistant perforations for engaging a spiked roller, and a marking for determining the type and quality of the conveyor belt as well as the length of the separated binding strips by means of a sensor. The conveyor belt is designed such that it can be automatically detected by a device for applying binding strips from a conveyor belt to sheet material by means of a sensor on the guide element and can be drawn in by a spiked roller acting as a feed device, and the binding strips can be applied to sheet material without waste by a pressure bar equipped with a cutting device.
