Solution Overview
Problem
Current sheet laminating processes are inefficient due to manual handling of adhesive films, requiring significant time and manpower, and are costly, with existing automated solutions being expensive and complex, while also facing challenges with film sticking issues and limited productivity when performing laminate processing on offline machines.
Innovation Solution
A sheet processing device that includes a separator, conveyor, and switching member to automate the separation and conveyance of two-ply sheets, allowing for the insertion of an inner sheet and optional fixing processing, with a common stacker for heat-pressed and non-heat-pressed sheets, reducing costs and size, and enabling offline laminate processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling of adhesive films is used for lamination, then the process can be performed on simple equipment, but the productivity is low and time consumption is high
Solution Approach 1:
The patent divides the lamination system into modular components: a separator unit that automatically separates the adhesive film from the backing sheet, a conveyor system that transports sheets through the lamination path, and a switching member that directs sheets to different output paths. This segmentation allows automated high-speed lamination without requiring a complete complex dedicated laminator, thus improving productivity while controlling device complexity.
Solution Approach 2:
The patent creates a multi-functional sheet processing device that can perform both lamination (with heat and pressure) and non-lamination (simple sandwiching) operations using the same basic structure. The switching member enables the system to adapt between different modes, making the equipment versatile and reducing the need for separate dedicated devices for different lamination needs.
2Extent of automation
If a dedicated laminator device using roll film is used to avoid manual work, then automation is achieved, but the cost becomes very high (hundreds of thousands of yen to millions of yen)
Solution Approach 1:
The patent employs disposable sheet-based lamination films instead of expensive roll film systems. The separator is designed to work with individual sheets that are fed through the system, eliminating the need for costly roll film dispensing mechanisms, tension control systems, and large inventory storage required by dedicated laminators. This approach achieves automation with much lower equipment costs.
Solution Approach 2:
The separator automatically separates the adhesive film from the backing sheet without requiring manual intervention. The conveyor system automatically transports sheets through the lamination path, and the switching member automatically directs sheets to appropriate output paths. This self-service automation eliminates the need for expensive operator interfaces and control systems found in dedicated laminators.
3Ease of operation
If manual pinching work is performed to separate films, then the separation can be achieved, but the operation is troublesome and time-consuming
Solution Approach 1:
The patent replaces the manual mechanical pinching action with an automated separator mechanism. The separator uses controlled mechanical forces to automatically separate the adhesive film from the backing sheet, eliminating the need for operators to manually pinch and pull films. This substitution dramatically improves ease of operation and reduces the time required for film separation.
4Manufacturing precision
If sheets are held in accurate position after peeling off, then positioning precision is achieved, but the handling becomes more complex
Solution Approach 1:
The patent designs the conveyor system and sheet handling paths to maintain sheets at consistent positions throughout the lamination process. The conveyor belts and guides are arranged to keep sheets aligned without requiring complex active positioning mechanisms. This equipotential approach ensures positioning accuracy while minimizing device complexity.

AI summary
A sheet processing device sandwiches a sheet-shaped medium in a two-ply sheet in which two sheets are overlaid and partially bonded. The sheet processing device includes a separator, a conveyor, and a switching member. The separator separates the two sheets of the two-ply sheet. The conveyor is disposed downstream from the separator in a sheet conveyance direction and conveys the two-ply sheet. The switching member is disposed downstream from the conveyor in the sheet conveyance direction. The switching member switches a conveyance path of the two-ply sheet to convey the two-ply sheet to a fixing path on which fixing processing is performed on the two-ply sheet or a non-fixing path on which no fixing processing is performed on the two-ply sheet.
