Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for applying adhesive and release liner to I-joists and other engineered wood products are often difficult to operate and fail to properly apply the adhesive and/or release liner, requiring manual adjustments and sometimes manual application of the release liner.
Innovation Solution
An automated adhesive and release liner application system featuring a frame with sliding tables and actuators, an adhesive head, release liner applicator, cutter, and staple gun, controlled by a subsystem to ensure precise application and automation of the adhesive and release liner on I-joist flanges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a specific machine is used to pre-apply adhesive and release liner to I-joist, then adhesive application is automated, but the machine is difficult to operate and fails to properly apply adhesive and/or release liner
Solution Approach 1:
The system automatically adjusts its own components through feedback from sensors. The processor receives signals from sensors detecting the I-joist position and automatically controls actuators to adjust the application head position, eliminating the need for manual adjustments and making the machine self-regulating
Solution Approach 2:
Sensors are positioned to detect the presence and position of the I-joist flange, sending signals to the processor which then adjusts the application parameters. This closed-loop feedback system ensures proper application while simplifying operation by removing the need for manual monitoring and adjustment
2Adaptability or versatility
If manual adjustments are required for the machine, then some flexibility is maintained, but operational complexity increases and reliability decreases
Solution Approach 1:
The system dynamically adjusts its configuration through actuators that move components based on real-time sensor feedback. The application head can automatically adjust its position and the adhesive application parameters are dynamically modified based on detected I-joist characteristics, providing both adaptability and reliability
Solution Approach 2:
Manual mechanical adjustment mechanisms are replaced with automated actuators controlled by a processor. The system uses electronic control and sensor feedback rather than manual mechanical adjustments, maintaining adaptability while significantly improving reliability by eliminating human error
3Ease of operation
If release liner is manually applied, then application flexibility is maintained, but productivity decreases and consistency is compromised
Solution Approach 1:
The adhesive application and release liner application processes are merged into a single integrated operation. The application head simultaneously deposits adhesive and applies the release liner in one continuous motion, eliminating the need for separate manual operations and significantly improving productivity while maintaining consistency
Solution Approach 2:
The system performs adhesive application and release liner application in a continuous, uninterrupted sequence. The actuators and applicators work continuously as the I-joist passes through, eliminating the start-stop nature of manual operations and ensuring consistent, high-speed application

AI summary
An adhesive and release liner application system and method. A bottom table is slidable with respect to a frame and a middle table is slidable with respect to the bottom table. An elevator drive subsystem between a top table and the middle table is configured to adjust the elevation of the top table relative to the middle table. An adhesive head, connected to an adhesive supply subsystem, a release liner applicator, a release liner cutter, and a staple gun are mounted to the top table for applying the adhesive to a surface of a structural member positioned adjacent the top table, for applying a release liner over the adhesive on the surface, for inserting at least one staple through the release liner and into the surface, and for cutting the release liner.
