Solution Overview
Problem
Existing methods for applying flexible spacer profiles in insulating glazing production are complex, inflexible, and time-consuming, particularly when replacing reels, leading to inefficiencies and limitations in production flexibility and the ability to handle multiple types of spacer profiles.
Innovation Solution
An automatic machine with a conveyor system, carriage, and application head that allows for the efficient unwinding and application of flexible spacer profiles from multiple reels, enabling continuous operation and quick switching between different profiles without interrupting the production line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single reel containing a flexible spacer profile is used, then the application process is simple, but the production flexibility and ability to handle multiple profile types are limited
Solution Approach 1:
The magazine is divided into multiple slots (at least two) that can independently hold different reels containing different flexible spacer profiles. This segmentation allows the system to store and quickly switch between multiple profile types without complex reconfiguration, directly improving production flexibility while maintaining manageable complexity through modular design.
Solution Approach 2:
The application head is designed with universal engagement capability to work with any reel mounted in the magazine slots. The take-up unit and transfer unit can handle different profile types through standardized interfaces, allowing a single machine configuration to serve multiple production needs across different insulating glazing types.
2Productivity
If manual reel replacement is used, then the machine structure is simple, but the operation time and production efficiency are reduced
Solution Approach 1:
The carriage is designed to be movable along the magazine, enabling automatic selection and engagement with different reels based on production requirements. This dynamic positioning system allows rapid reel replacement without manual intervention, significantly improving production efficiency while the automated control reduces operational complexity.
Solution Approach 2:
The take-up unit automatically engages with the flexible spacer profile from the selected reel and feeds it to the application head without manual assistance. The system self-regulates the profile feeding process, including tension control and positioning, eliminating the need for operator intervention during reel changes and持续提升ting productivity.
3Manufacturing precision
If the reel is fixed to the ground, then the installation is simple, but the distance to the glass sheet is considerable and variable, reducing application precision
Solution Approach 1:
Instead of fixing reels to the ground (horizontal plane), the magazine is positioned vertically above the glass sheet, utilizing the vertical dimension. This dimensional change dramatically reduces the distance between the reels and glass sheet, improving application precision while the vertical mounting structure maintains installation simplicity.
Solution Approach 2:
The transfer unit acts as an intermediary mechanism between the reels and the application head. It precisely controls the delivery of the flexible spacer profile from the reels to the glass sheet, ensuring accurate positioning and application while compensating for any dimensional variations in the reel-to-glass-sheet distance.
4Adaptability or versatility
If a complex reel replacement process is used, then multiple profile types can be handled, but the time consumption and waste of spacer profile increase
Solution Approach 1:
Multiple reels containing different flexible spacer profiles are pre-loaded into the magazine slots before production begins. This preliminary preparation allows instant switching between profile types during production without time-consuming replacement operations, eliminating both time loss and material waste associated with reel changes.
Solution Approach 2:
The system maintains continuous production operation by keeping multiple reels ready in the magazine. When one reel is depleted, the carriage automatically positions the next reel into the active position without interrupting the production flow, ensuring continuous useful action and eliminating downtime that would cause time loss and material waste.

AI summary
An automatic machine and an automatic method for the alternating application of a plurality of flexible spacer profiles, preferably made of expanded synthetic material, on a glass sheet in order to compose the insulating glazing, where a dynamic magazine, which contains a plurality of reels of flexible spacer profile is paired with an application head and the path of the flexible spacer profile lies around the rotation axis of the application head, thus rendering feeding from the magazine compatible, thereby allowing the alternability of the reels, with the functionality of the application head, which requires a 360° freedom of rotation.
