Solution Overview
Problem
Existing sheet transfer processes face challenges in efficiently transferring multilayer-laminated sheets without defects, leading to increased process time and cost due to the adherence of sheets and metal sticks, which can result in damage and misalignment during the transfer process.
Innovation Solution
A sheet transfer apparatus with a table and adsorbing and releasing units, including sheet adsorbing parts, air discharge parts, and an elevation unit, which allows for continuous lamination and transfer of sheets by adsorbing the uppermost sheet, elevating it, and using air discharge to separate the subsequent sheets, thereby minimizing defects and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sheets are continuously laminated and transferred using conventional methods, then productivity is improved, but sheets adhere to each other and to metal sticks causing defects and damage
Solution Approach 1:
The patent uses a suction table with vacuum ports to create negative pressure that holds sheets in place during transfer. Air blowers apply positive pressure to separate sheets from the table and from each other. This pneumatic system enables continuous sheet handling without adhesion-related defects.
Solution Approach 2:
The suction table acts as an intermediary between the sheet stack and the transfer mechanism. By controlling vacuum pressure and air blow pressure, the table mediates sheet separation and transfer, preventing direct contact and adhesion between sheets and metal sticks.
2Reliability
If sheets are transferred one by one, then sheet separation is improved, but process time increases
Solution Approach 1:
The suction table continuously holds multiple sheets in place while air blowers periodically separate and transfer them. This continuous positioning with periodic transfer actions eliminates idle time between transfers while maintaining sheet separation through controlled pneumatic pressure.
Solution Approach 2:
Air blowers apply periodic bursts of pressure to separate sheets from the suction table in a rhythmic manner. This periodic action enables continuous transfer process where sheets are separated and transferred in sequence without stopping the overall process.
3Reliability
If air discharge is applied to separate sheets, then sheet separation is improved, but sheets may become misaligned
Solution Approach 1:
The suction table creates uniform negative pressure across its surface, holding sheets in consistent positions. This equipotential pressure distribution ensures that when air blowers separate sheets, they remain aligned with the table edges and with each other, preventing misalignment.
Solution Approach 2:
Air blowers are positioned at specific locations and apply pressure locally to separate sheets without disrupting overall alignment. The localized air pressure application allows sheet separation while maintaining precise positioning relative to the suction table boundaries.
