Container Fill Station Flow Control for Precision Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container filling apparatuses are either slow or expensive, and lack sufficient control for accurate and repeatable filling, which can compromise the integrity of beverages or liquids in containers.
Innovation Solution
A container fill station with a fill head system, seal bar gantry, and flow control system that allows for precise filling and sealing of containers, enabling both counter-pressure and atmospheric pressure filling, with features like a seal bar that can contact multiple containers simultaneously and a flow control system that manages liquid and gas flow to prevent overflow and foaming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If known container filling apparatus are used, then filling can be automated, but the filling speed is relatively slow
Solution Approach 1:
The fill head is divided into multiple independent nozzles that can be selectively positioned and controlled. Each nozzle can be independently actuated to fill specific containers, allowing parallel processing and increased throughput while maintaining precise control over each filling operation.
Solution Approach 2:
The fill head incorporates movable components including extendable arms and adjustable nozzles that can dynamically reposition themselves. This dynamic positioning enables the system to adapt to varying container positions and sizes, maintaining filling accuracy while operating at higher speeds.
2Extent of automation
If known container filling apparatus are used, then filling can be automated, but the equipment is relatively expensive
Solution Approach 1:
The fill head is designed as a universal assembly that can handle multiple container types and filling scenarios through programmable control. The same basic mechanism can perform different filling operations by adjusting parameters, reducing the need for multiple specialized devices and lowering overall system cost.
Solution Approach 2:
The system incorporates self-aligning features and automatic positioning mechanisms that reduce the need for complex external alignment systems. The fill head can autonomously adjust its position and orientation based on sensor feedback, simplifying the overall automation architecture.
3Manufacturing precision
If known container filling apparatus are used, then filling can be automated, but they do not provide sufficient control over filling operations to assure accurate and repeatable fill
Solution Approach 1:
The fill head incorporates sensors that monitor filling progress and provide real-time feedback to the control system. This feedback mechanism allows the system to automatically adjust filling parameters to maintain precise and repeatable fills, while the user benefits from simplified operation through automated control.
Solution Approach 2:
The system allows dynamic adjustment of filling parameters such as flow rate, pressure, and timing. Users can modify these parameters to optimize filling for different container types and liquid viscosities, maintaining high precision across varying operating conditions without complicating operation.
4Reliability
If known container filling apparatus are used, then filling can be automated, but they do not assure the integrity of the beverage or other liquid placed into the container
Solution Approach 1:
The fill head incorporates features that prevent common filling defects such as overflow, foaming, and contamination before they occur. By controlling liquid flow and air displacement in advance, the system protects product integrity without requiring complex post-filling correction mechanisms.

AI summary
A container fill station includes a seal bar configured to temporarily contact an open end of a container, to temporarily seal an interior of the container from a surrounding atmosphere, a fill head configured to be moved by a fill head actuator through a sealed opening in the seal bar, a fill head valve located in a fluid pathway between a liquid source and the fill head outlet, and an outflowing gas valve in fluid communication with the interior of the container. Therein, control of a liquid fill rate is provided by opening the outflowing gas valve a select amount while simultaneously opening the fill head valve. During a filling operation method, the interior of the container may be temporarily sealed and pressurized, or filling may be done at ambient/atmospheric pressure, preferably with the fill head outlet being disposed below the liquid's surface during filling.
