Laminating Roller Parallel Linkage Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laminating devices face challenges in achieving uniform force distribution across the entire width of laminating rollers due to variations in the position and thickness of glass sheets or other sheet-like objects, making it difficult to adjust pressure correctly.
Innovation Solution
A device with parallel links connected to a coupling rod, where only one link is driven, ensures constant adjustment of the adjustable laminating roller across the entire width, applying consistent pressure through compression springs and a force measuring device, allowing for precise control of the pressing force regardless of the object's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional adjustable roller mechanisms are used with multiple drives, then the gap width can be adjusted, but the force distribution across the roller width becomes non-uniform
Solution Approach 1:
The adjustment mechanism is segmented into parallel links that are distributed across the width of the roller. Each link independently transmits the driving force to the roller, ensuring uniform force distribution across the entire width while maintaining a relatively simple individual link structure
Solution Approach 2:
Multiple parallel links are merged into a single coordinated adjustment system driven by one motor. The links work together in unison through the coupling rod to provide synchronized adjustment across the roller width, achieving uniform pressure distribution without requiring multiple independent drive systems
2Reliability
If the position and thickness of glass sheets vary, then lamination quality may be affected, but adjusting pressure for each variation is difficult
Solution Approach 1:
The system incorporates a force measuring device that dynamically monitors the pressing force and provides feedback to the control unit. The control unit automatically adjusts the motor drive to maintain constant force despite variations in sheet position or thickness, ensuring consistent lamination quality without manual intervention
Solution Approach 2:
A feedback control system is implemented where the force measuring device continuously measures the actual pressing force and communicates this information to the control unit. The control unit compares the measured force with the target force and adjusts the motor operation accordingly, maintaining reliable lamination quality automatically

Function Achieved in This Case
This configuration ensures uniform force distribution and precise pressure control across the laminating rollers, resulting in a rigid and compact construction that maintains consistent pressure over the entire width, independent of the object's position, enhancing the lamination process.

AI summary
A device for laminating plate-shaped articles, in particular glass panes, has two laminating rolls (2, 9), of which at least one laminating roll (2) is driven and between which the plate-shaped articles for laminating are guided through. One laminating roll (2) is preferably mounted fixedly in a machine frame (1) and the other laminating roll (9) is mounted adjustably in the machine frame (1). The roll (9) which is mounted adjustably in the machine frame (1) is mounted in the region of the ends of said roll (9) in bearings (11) which are connected to parallel links (25, 26). The parallel links (25, 26) are mounted in the machine frame (1) and are connected to one another by means of a coupling rod (32). One of the two parallel links (25) is connected to a drive (37).
