Filler Nozzle Suction Channel for Automated Substance Purging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging installations require large and complex collectors for changing substances, which hinder automation due to the need for operator intervention.
Innovation Solution
Incorporating a suction channel at the bottom end of the filler spout with a controlled delivery valve, allowing for the external removal of residual substance without opening the valve, thus eliminating the need for large collectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a collector is used to drain remaining substance from the filler station, then the substance can be purged effectively, but the installation size increases and operator intervention is required
Solution Approach 1:
The suction channel extracts the remaining substance from the filler station directly through the spout body, removing the need for a separate collector component. This extraction approach eliminates the large-volume collector while maintaining effective substance purging, directly resolving the contradiction between purging effectiveness and installation size.
Solution Approach 2:
The suction channel acts as an intermediary element between the filler station interior and the external suction source. It provides a dedicated pathway for removing remaining substance without requiring a large collector, enabling effective purging while keeping the installation compact and suitable for automation.
2Adaptability or versatility
If a collector is used to collect and drain remaining substance, then substance changeover is possible, but the system becomes complex and requires operator intervention
Solution Approach 1:
The suction channel extracts the substance removal function directly from the spout body, eliminating the need for a separate collector system. This simplifies the overall device structure while maintaining full substance changeover capability, directly addressing the contradiction between adaptability and device complexity.
Solution Approach 2:
The suction channel enables the filler station to perform its own substance purging operation through the controlled delivery valve and suction channel combination. This self-service capability eliminates the need for operator intervention and complex collector systems, achieving both substance changeover and simplified device structure.
3Loss of substance
If the delivery valve is opened to drain substance, then substance can be removed from the spout, but the valve must be opened which complicates the automation process
Solution Approach 1:
The substance removal function is segmented into a separate suction channel that operates independently from the controlled delivery valve. This segmentation allows substance to be removed through the suction channel while the valve remains closed, improving substance removal efficiency while enabling full automation without valve opening.
Solution Approach 2:
The suction channel serves as an intermediary pathway that bypasses the need to open the controlled delivery valve for substance removal. This intermediary route enables efficient substance extraction while keeping the valve closed, thereby maintaining automation capability and improving substance removal efficiency simultaneously.
