Filling Spout Return Line Series Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging installations for substances suffer from significant substance loss and excessive cleaning substance consumption during initial filling and substance changes due to the need for prolonged purging and the reuse of collectors for both purposes.
Innovation Solution
The installation employs a multichannel connection member that connects the feed duct, supply pipe, and purge duct in series, allowing for quick initial filling and substance changes with minimal substance rejection, and optionally includes a pump for controlled substance admission, reducing the need for large collectors and washing water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the collector is used for recovering substance during initial filling of filler spouts, then substance can be recovered, but the collector cannot be reused for cleaning substance recovery and significant substance loss occurs
Solution Approach 1:
The invention divides the single collector into two separate collectors: a first collector dedicated to recovering substance during initial filling of filler spouts, and a second collector for recovering cleaning substance. This segmentation allows each collector to be optimized for its specific purpose, enabling the first collector to be reused for substance recovery while the second handles cleaning waste, thereby reducing overall substance loss and improving system versatility.
2Reliability
If substance flows for a relatively long length of time to purge air from feed duct, then air bubbles are removed from spout, but non-production time increases
Solution Approach 1:
The invention introduces a pump that actively removes air bubbles from the feed duct and spout body before substance filling begins. This preliminary air removal action eliminates the need for prolonged substance flow to purge air, as the air is removed in advance by the pump system, thereby significantly reducing non-production time while ensuring reliable air-free filling.
3Volume of stationary object
If the same collector is used for both substance recovery and cleaning substance recovery, then space is saved, but substance processing cost increases
Solution Approach 1:
The invention separates the single collector into two distinct collectors: a first collector for substance recovery and a second collector for cleaning substance recovery. This segmentation increases the total volume occupied by collector systems but eliminates the need to process mixed substances together, allowing each collector to handle its specific substance type independently, thereby reducing processing costs and improving substance recovery efficiency.

AI summary
A packaging installation having at least one filler station includes a filler spout and a connection member connected firstly to a feed duct and secondly to a purge duct in order to connect these ducts to the spout. The connection member includes a spout supply pipe connected to the feed duct and a return pipe opening out into the spout and connected to the purge duct. The supply pipe and the return pipe are entirely independent of each other, such that the connection member acts continuously to connect in series the feed duct, the supply pipe, the spout, the return pipe, and the purge duct.
