Double-Sided Green Sheet Handling for Damage-Free Release Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceramic green sheets, particularly thin ones, are prone to damage during handling due to their lack of strength and are difficult to handle without causing damage, especially when a release agent needs to be adhered to both surfaces.
Innovation Solution
A double-sided treatment device that includes a first conveyance mechanism, first and second roller parts, and treatment parts to invert and treat both surfaces of the ceramic green sheet, applying a release agent uniformly while minimizing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a release agent is adhered to two surfaces of a ceramic green sheet after cutting, then waste of ceramic green sheet is reduced, but handling difficulty and damage risk increase due to thinness and softness
Solution Approach 1:
The release agent is adhered to both surfaces of the ceramic green sheet before cutting into prescribed shapes. This preliminary action prevents damage during subsequent handling and cutting operations, while also reducing waste by eliminating the need for excessive margins around cut edges.
Solution Approach 2:
A release agent serves as an intermediary substance applied to the ceramic green sheet surfaces. This intermediary layer protects the fragile green sheet during handling and processing, reducing direct mechanical stress and damage risk while enabling efficient double-sided treatment.
2Productivity
If a release agent is adhered to two surfaces of a ceramic green sheet, then processing efficiency is improved, but device complexity increases due to need for double-sided treatment mechanism
Solution Approach 1:
The device inverts the ceramic green sheet between first and second treatment portions, allowing both surfaces to be treated in sequence within a single pass. This inversion mechanism enables double-sided release agent application without requiring separate handling operations for each surface.
Solution Approach 2:
The treatment device combines multiple functions into a single integrated system: conveyance mechanisms for moving the green sheet, inversion mechanisms for flipping it, and treatment portions for applying release agent to both surfaces. This merging of functions achieves double-sided treatment in one operation, improving productivity while managing device complexity through integration.

AI summary
A double-sided treatment device according to an embodiment adheres a release agent to two surfaces of a ceramic green sheet. The double-sided treatment device includes a first conveyance mechanism, a first treatment part, a first roller part, a second roller part, a second conveyance mechanism, and a second treatment part. The first conveyance mechanism moves the ceramic green sheet in a first direction. The first treatment part adheres the release agent to a first surface of the ceramic green sheet conveyed by the first conveyance mechanism. The first roller part is located at an end part in the first direction of the first conveyance mechanism, and changes a movement direction of the ceramic green sheet to a second direction crossing the first direction. The second roller part changes the movement direction of the ceramic green sheet that moved in the second direction to an opposite direction of the first direction. The second conveyance mechanism moves the ceramic green sheet in the opposite direction. The second treatment part adheres the release agent to a second surface of the ceramic green sheet conveyed by the second conveyance mechanism.
