Rotary Glue Valve Feedthrough With External Filter Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glue valve arrangements face challenges with filter replacement, as it requires handling hot glue, risking burns, and necessitates modifications to the base body for filter placement, leading to a less compact design.
Innovation Solution
The filter is relocated to the rotary feedthrough outside the base body, allowing for easier and safer replacement, and eliminating the need for holes in the base body, enabling a more compact design with a detachable filter holder and swivel joint for relative movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the filter is housed in the base body of the glue valve assembly, then the filtration function is provided, but the base body requires complex holes for filter placement and cannot be constructed more compactly
Solution Approach 1:
The filter is extracted from the base body and relocated to the rotary feedthrough assembly. The filter is now housed in a filter holder that is part of the rotary feedthrough, which connects to the base body via a detachable connection. This extraction eliminates the need for complex holes in the base body and allows for a more compact base body design while maintaining the filtration function.
2Ease of operation
If the filter is housed in the base body, then filtration is achieved, but the filter can only be changed when the glue is still hot and liquid, posing an acute risk of burns
Solution Approach 1:
The filter is extracted from the base body and relocated to the rotary feedthrough assembly with a detachable connection. This allows the filter to be changed by simply detaching the rotary feedthrough from the base body, enabling filter replacement without handling hot glue and eliminating the burn risk associated with in-situ filter changes.
Solution Approach 2:
The system is segmented into a base body and a rotary feedthrough assembly with detachable connection. The filter is part of the rotary feedthrough assembly, which can be separated from the base body. This segmentation enables the filter to be replaced by detaching the rotary feedthrough, allowing filter changes without exposure to hot glue.
3Adaptability or versatility
If the filter is housed in the base body, then the filtration function is provided, but relative movement between components is restricted
Solution Approach 1:
The filter is extracted from the base body and integrated into the rotary feedthrough assembly. The rotary feedthrough is detachably connected to the base body, enabling relative movement and articulation between these components for maintenance or assembly purposes, while maintaining the filtration function through the filter holder in the rotary feedthrough.

AI summary
The invention relates to a glue valve arrangement comprising a controllable, in particular electromagnetically operated proportioning device for delivering glue, comprising a main body (15) having a glue channel leading to the proportioning device, comprising a hose-like glue conduit (16), by which glue originating from a separate glue source can be delivered to the glue channel, comprising a rotary feedthrough (20) releasably fastened to the main body (15) for articulated connection of the hose-like glue conduit (16) to the main body (15), and comprising a filter (34) for filtering the glue. The invention is characterised in that the filter (34) is associated with the rotary feedthrough (20).
