Displaceable Nozzle Unit for Flexible Adhesive Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive application devices are inflexible and costly due to the need for multiple gumming rollers and complex cleaning processes, especially when dealing with varying window sizes and positions, leading to prolonged downtimes and inefficiencies.
Innovation Solution
A displaceable nozzle unit with multiple nozzles and gluing heads, arranged along a guide spindle transverse to the material's direction of transport, allows for flexible adaptation to different gluing patterns and efficient cleaning through automated signal units and cleaning stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed nozzle system is used for adhesive application, then the structure is simple and stable, but it cannot adapt to different gluing formats and positions
Solution Approach 1:
The nozzle unit is made displaceable along a guide spindle transverse to the material transport direction, allowing dynamic repositioning to accommodate different gluing formats and positions without replacing entire format-specific components
Solution Approach 2:
A single nozzle unit with multiple nozzles can serve multiple gluing formats and positions by being repositioned along the guide spindle, replacing the need for multiple fixed format-specific nozzle systems
2Adaptability or versatility
If multiple gumming rollers are used for different formats, then each format can be processed, but the device complexity increases and costs rise
Solution Approach 1:
One universal nozzle unit with multiple nozzles replaces multiple format-specific gumming rollers, capable of processing different formats through repositioning along the guide spindle
Solution Approach 2:
The nozzle unit comprises multiple individual nozzles that can be selectively activated, allowing flexible configuration for different gluing patterns without requiring separate rollers for each format
3Manufacturing precision
If metering nozzles are positioned close to the material for precise application, then adhesive precision improves, but cleaning becomes difficult and downtime increases
Solution Approach 1:
The nozzle unit can be dynamically repositioned away from the material during cleaning operations and returned to the precise gluing position during operation, enabling easy access for maintenance while preserving application precision
Solution Approach 2:
The system is designed to facilitate preliminary cleaning actions by providing easy access to nozzles through the displaceable mechanism, preventing clogging before it affects production
4Manufacturing precision
If format-specific gumming rollers are used, then each format receives optimized adhesive application, but changing formats requires stopping production and replacing rollers
Solution Approach 1:
The displaceable nozzle unit allows rapid repositioning between different gluing positions for format changes without stopping production, maintaining optimized adhesive application while eliminating roller replacement downtime
Solution Approach 2:
The system changes the position parameter of the nozzle unit along the guide spindle to adapt to different formats, replacing the need for physical roller changes while maintaining application optimization

AI summary
An adhesive application device for applying, includes a nozzle unit having a number of nozzles for applying an adhesive to a material which is moved along a direction of transport, said nozzles being displaceable transversely to the direction of transport along a first guide spindle; and plural individual gluing heads, each being arranged separately from each other on respective second separate guide spindles, so as to be displaceable transversely to the direction of transport.
