Adhesive Dispenser Embossing Roller for Sheath Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting flattened tubular sheaths at high speeds are inefficient due to complex adhesive dispenser arrangements and manual handling, which complicates the automation of the duct connection process.
Innovation Solution
A simplified adhesive dispenser with an embossing roller to stiffen the adhesive tape before separation, combined with a saber blade-shaped separation member and tensioning rollers, facilitates easier application and connection of sheaths, and includes a cutting mechanism for precise adhesive delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complex adhesive dispenser arrangement with a fan is used to blow on the adhesive strip, then the adhesive can be removed more easily, but the device structure becomes overly complicated
Solution Approach 1:
The patent extracts the fan component from the adhesive dispenser system, removing the complex blowing mechanism while retaining the essential adhesive application function through a simplified dispenser design that relies on adhesive tape stiffness and separation geometry rather than active air flow
Solution Approach 2:
The adhesive tape is designed to be self-sufficient through embossing-induced stiffness, allowing it to be separated and applied without requiring external assistance from a fan or blowing mechanism. The tape's own structural properties enable its function
2Productivity
If manual handling methods are used for connecting sheaths, then the process can be performed with simple equipment, but the connection speed becomes too slow for high production rates
Solution Approach 1:
The adhesive tape is pre-embossed with a pattern that creates stiffness before application, preparing it in advance for rapid separation and application. This preliminary structural preparation enables high-speed automated handling without requiring complex real-time control mechanisms
Solution Approach 2:
The embossing process changes the physical parameters of the adhesive tape by creating a stiffened structure through deformation. This parameter change (from flexible to stiffened) enables the tape to be handled at high speeds while maintaining control and precision in the connection process
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables efficient and automated connection of tubular sheaths by stiffening the adhesive tape, ensuring reliable adhesion and easy handling, even at high speeds, and simplifies the adhesive application process for long lengths.
Implementation Method 1
an embossing roller arranged on the platform between the dispenser and the separating member so as to, in service, emboss an adhesive tape unwinding from the adhesive roller before it reaches the separating member
Implementation Method 2
The device comprises a trolley that allows the terminal end of an old sheath to be aligned with the initial end of a new sheath. The trolley also includes an adhesive dispenser, which discloses the characteristics of the preamble of claim 1, enabling the two ends to be bonded together
