Solution Overview
Problem
Existing sheet processing technologies face challenges in efficiently separating and inserting inner sheets into laminated sheets, particularly in creating a stable sagging space for reliable separation and ensuring accurate positioning of separation claws, which affects the lamination process.
Innovation Solution
A sheet processing device that includes a conveyor, rotator, and control circuitry to convey and wind a two-ply sheet, creating a sagging space and using separation claws to insert an inner sheet between the sheets, with mechanisms to adjust the conveyance direction and position the sagging space for stable insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the two-ply sheet is conveyed at constant speed without reverse conveyance, then the conveyance process is simple, but the separator cannot be accurately inserted into the sagging space
Solution Approach 1:
The conveyor performs periodic reverse conveyance at specific intervals during the sheet processing. The control circuitry triggers reverse conveyance when the sagging space reaches a predetermined position, allowing the separator to be accurately inserted. This periodic reversal resolves the contradiction by providing the necessary positioning accuracy without requiring continuously complex control mechanisms.
2Reliability
If additional lamination sheet branching members are added to create sagging space, then separation reliability is improved, but device complexity and cost increase
Solution Approach 1:
The invention extracts the sagging space creation function from physical branching members and transfers it to the conveyor's reverse conveyance action. By removing the need for additional branching members and using only the conveyor's directional control, the system achieves reliable separation while reducing device complexity and cost.
Solution Approach 2:
The two-ply sheet itself creates the sagging space through the reverse conveyance action, without requiring external branching members. The sheet's own flexibility and the conveyor's motion work together to generate the necessary separation space, making the system simpler and more cost-effective.
3Measurement precision
If the conveyor continuously conveys the two-ply sheet in one direction, then the processing speed is maintained, but the separator insertion timing and position cannot be controlled
Solution Approach 1:
The conveyor alternates between forward conveyance (maintaining productivity) and brief reverse conveyance (enabling precise positioning). This periodic action allows the system to achieve both high processing speed and precise sagging space positioning by only reversing when necessary for separator insertion.

AI summary
A sheet processing device includes a conveyor, a rotator, a separator, and control circuitry. The conveyor conveys a two-ply sheet in which two sheets are overlapped and bonded together at a portion of the two-ply sheet. The rotator winds the two-ply sheet. The control circuitry causes the conveyor to convey the two-ply sheet in a winding direction to wind the two-ply sheet around the rotator such that a sagging space is created in the two-ply sheet, and causes the separator to insert into the sagging space to separate the two-ply sheet into two sheets. The control circuitry causes the conveyor to convey the two-ply sheet in a direction opposite the winding direction before an insertion of the separator into the sagging space.
