Beverage Filling Device Defect Mode Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the filling of beverage bottles, particularly oxygen-sensitive drinks, damaged bottles can break during prestressing, leading to glass splinters and contaminants being drawn into the filling device's evacuation and relief channels, causing damage and potential contamination of subsequent bottles.
Innovation Solution
Implementing a dual filling mode system where regular bottles are filled using a first mode involving evacuation, flushing, prestressing, and controlled relief, while bottles following a defect are filled using a second mode that excludes evacuation and controlled relief, utilizing only volume flows to flush out contaminants and prevent their entry into the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If evacuation and controlled relief are performed during regular filling, then filling quality and oxygen removal are improved, but glass splinters and contaminants from broken bottles can be drawn into the device channels
Solution Approach 1:
The system dynamically switches between two filling modes based on detected bottle defects. In normal mode, evacuation and controlled relief are performed for quality filling. Upon detecting a broken bottle, the system transitions to safety mode where these operations are suppressed, preventing contaminant ingress while maintaining operational continuity
Solution Approach 2:
The control unit receives feedback about bottle integrity (through detection of broken bottles during prestressing) and adjusts the filling process accordingly. When defects are detected, the control unit suppresses evacuation and controlled relief operations, creating a feedback loop that prioritizes device safety over filling quality
2Productivity
If the filling element continues operation after a bottle break, then productivity is maintained, but contaminants can damage valve seats and compromise subsequent bottles
Solution Approach 1:
The filling process is segmented into distinct operational phases: normal filling mode and safety mode. The control unit divides the operation based on defect detection, allowing the system to maintain productivity through continuous operation while isolating contaminant risks through mode segmentation
Solution Approach 2:
The system converts the harmful event of a broken bottle into a beneficial safety mechanism. By detecting the break and automatically suppressing evacuation and relief operations, the system uses the defect detection to trigger protective measures that prevent broader contamination, turning a potential disaster into a controlled safety response

Function Achieved in This Case
This approach effectively prevents glass splinters and contaminants from entering the filling device, reducing wear and ensuring the safe removal of partially filled bottles, thereby enhancing the reliability and cleanliness of the filling process.
Implementation Method 1
the interior of the beverage bottle is flushed with a gas, for example with CO2, in order to reduce the oxygen content in the bottle
Implementation Method 2
the interior of the beverage bottle is flushed with a gas, for example with CO2
Implementation Method 3
the beverage bottle is also typically depressurized in a controlled manner to reduce foam formation

AI summary
The liquid filling method involves operating filling element (10) in a filling mode, for regular filling of the container (G) with the liquid (F). The filling element is operated according to the defect of the container in a machine cycle at the next filling mode. The container is biased before loading liquid in container. The container is compressed after filling liquid in container. The container is rinsed using the flushing gas. An independent claim is included for device for filling liquid in container.
