Layered Sheet Alignment by Tilted Pitch Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing layered products face inefficiencies due to misalignment of sheet materials caused by size differences resulting from manufacturing errors or deformation, leading to reduced production efficiency.
Innovation Solution
A method and device that adjust the arrangement pitch of sheet materials by tilting them relative to the transfer direction, allowing for precise alignment and synchronization of first and second sheet materials, even when they have different sizes, through mechanisms like the first and second arrangement units and the controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sheet materials are arranged successively without interruption to maintain production efficiency, then productivity is improved, but manufacturing precision deteriorates due to gradual misalignment of arrangement positions
Solution Approach 1:
The patent introduces a dynamic adjustment mechanism that tilts the arrangement direction of sheet materials relative to the transfer direction. This dynamic adjustment allows the arrangement pitch to be modified in real-time, compensating for size variations and maintaining precise alignment positions without interrupting the continuous transfer process, thus resolving the contradiction between productivity and manufacturing precision.
Solution Approach 2:
The patent changes the parameter of arrangement pitch by tilting the sheet materials at a specific angle with respect to the transfer direction. This parameter change allows the effective arrangement pitch to be adjusted to match the actual sheet material dimensions, ensuring precise alignment while maintaining continuous production flow.
2Manufacturing precision
If the transfer of sheet materials is interrupted to realign positions, then manufacturing precision is improved, but productivity deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-calculating and pre-setting the tilt angle and arrangement pitch adjustment before the sheet materials are transferred. This allows the system to be prepared in advance with the correct alignment parameters, eliminating the need for interruptions during the transfer process to realign positions.
3Adaptability or versatility
If sheet materials with different sizes are used to accommodate manufacturing variations, then adaptability is improved, but manufacturing precision deteriorates due to size differences
Solution Approach 1:
The patent changes the arrangement pitch parameter based on the actual size of each sheet material by tilting the arrangement direction. This parameter adjustment compensates for size variations in sheet materials, allowing the system to accommodate manufacturing variations while maintaining precise arrangement positions through the tilted configuration.

AI summary
A method for manufacturing a layered product includes: a first arranging step of continuously arranging first sheet materials in a transfer passage for performing transfer of a plurality of sheets along a transfer direction of the transfer passage; and a second arranging step of continuously arranging second sheet materials along the transfer direction above the first sheet materials arranged side by side in the transfer passage. In the second arranging step, the second sheet materials are arranged at downstream positions of the transfer passage with respect to arrangement positions of the first sheet materials. In the first arranging step and the second arranging step, an arrangement pitch of the first sheet materials or the second sheet materials in the transfer direction is adjustable by tilting the first sheet materials or the second sheet materials with respect to the transfer direction.
