Solution Overview
Problem
Existing devices for producing insulating glass panes with elastoplastic spacer strips face inefficiencies in quickly changing spacer widths and designs, leading to laborious threading and unthreading processes, especially when producing multiple panes with varying air gaps.
Innovation Solution
A device with multiple storage locations for elastoplastic spacer strips, a movable applicator head, and a coating station with adjustable nozzles allows for easy selection and application of spacer strips of different widths and designs, enabling quick switching between strips without laborious threading or unthreading, and includes features for cutting and V-shaped incisions to accommodate various requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single storage reel for elastoplastic spacer strip is used, then the device structure is simple, but changing spacer strip width requires laborious threading and unthreading operations
Solution Approach 1:
The single storage reel is segmented into multiple storage reels (first storage reel, second storage reel, etc.), each holding spacer strips of different widths. This segmentation allows rapid switching between different spacer widths by simply changing which reel is active, eliminating the need for threading and unthreading operations while maintaining operational simplicity through modular design.
2Productivity
If multiple storage reels for different spacer strip widths are provided, then spacer strip changeover is rapid and efficient, but the device structure becomes more complex
Solution Approach 1:
The device incorporates a movable applicator head that can dynamically adjust its position and the active storage reel selection based on the required spacer width. This dynamic capability allows the system to quickly adapt between different spacer configurations without requiring complete disassembly or complex reconfiguration, thereby improving productivity while managing device complexity through flexible, adaptive design.
3Adaptability or versatility
If the applicator head is fixed, then the device structure is simple, but it cannot accommodate spacer strips of different widths efficiently
Solution Approach 1:
The applicator head is designed to be movable along the glass pane surface, enabling it to adapt to different spacer strip widths by adjusting its position. This dynamic positioning capability allows the same applicator head to work with various spacer widths without requiring multiple fixed applicators or complex reconfiguration mechanisms, thereby improving versatility while keeping the device structure relatively simple.

Implementation Method 1
a coating station (10) with two pairs of nozzles (11, 12) for coating the selected spacer strip (1, 1') with adhesive
Implementation Method 2
strongly adhesive (which is desirable for a gas-tight connection initially with the first and later the second glass pane)

AI summary
The invention relates to a device for applying an elastoplastic spacer tape (1, 1') as a spacer during production of insulating glass panes, comprising at least two supply reels (2) for spacer tapes (1, 1'), several driven tape-guiding rollers (4, 6, 7, 8), and a movable application head (20) for the selected spacer tape (1, 1'), by means of which application head the spacer tape (1 or 1') is pressed onto a glass pane (40). A coating station (10) having two coating nozzles (11, 12) is provided for coating the one or the other spacer tape (1, 1'), wherein adhesive (butyl rubber) is sprayed onto the lateral surfaces of the selected spacer tape (1, 11). In the application head (20), each unneeded spacer tape (1 or 1') is stopped so that the one or the other spacer tape (1, 1'), depending on which spacer tape (1, 1') is needed for the production of a specific insulating glass pane, is applied to the glass pane (40). Thus, it is not necessary to laboriously thread and unthread spacer tapes (1, 1') into the device, and time is saved.
