Filling Line Control Unit Redirects Product Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filling lines face inefficiencies in minimizing product waste and optimizing production flow, particularly in cheese-filling lines where frequent product changes and variations in container sizes lead to significant losses and logistical challenges.
Innovation Solution
A method and device that redirect the product supply to a single filling machine as a batch nears completion, ensuring the last containers are filled to capacity and allowing for efficient preparation and reuse of filling machines, utilizing a control unit and valve system to manage the flow and minimize waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If product supply is continued to all filling machines until batch completion, then production continuity is maintained, but product waste increases due to partially filled containers
Solution Approach 1:
The control unit redirects product supply to a single filling machine before the batch is completely depleted, ensuring that the last containers are filled to their intended capacity. This preliminary redirection prevents the scenario where multiple machines would produce partially filled containers, thereby minimizing product waste while maintaining production continuity through proper timing of the supply redirection.
2Loss of time
If multiple filling machines operate simultaneously, then production speed is maintained, but preparation time for next batch is reduced
Solution Approach 1:
When the batch is about to be finalized, the control unit redirects product supply to a single filling machine, allowing the other machines to stop and prepare for the next batch or product type. This enables parallel preparation activities on idle machines while one machine completes the current batch, effectively utilizing preparation time without compromising the completion of the current production run.
3Manufacturing precision
If product supply is redirected to one filling machine, then container filling accuracy is improved, but equipment utilization decreases
Solution Approach 1:
The system dynamically adjusts the number of active filling machines based on the batch status. When a new batch starts, multiple machines operate simultaneously to maximize throughput. When the batch is about to be finalized, the system transitions to a single machine mode to ensure accurate filling of the last containers. This dynamic adjustment optimizes both filling accuracy and equipment utilization at different stages of the production cycle.

AI summary
A method for controlling a filling line, the filling line comprising at least one product-supply unit arranged to supply a batch of product and fluidly connected to at least two filling machines, a first filling machine and a second filling machine. Each filling machine is configured to fill a product into a container and the method comprises redirecting the supply of product to a single one of said at least two filling machines.
