Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging systems face challenges with container dimensional deviations leading to jamming, defective packs, and long ramp-up times, requiring skilled personnel to adjust packing stations, resulting in high reject rates.
Innovation Solution
The system incorporates additional measuring devices to determine dimensional deviations of both containers and packaging material, allowing for automatic adjustments of working components at the packing station, including temperature control and rail adjustments, to prevent jams and ensure correct packing density without the need for trained operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of packing station components is used to handle container dimensional deviations, then the system can process containers with varying dimensions, but the ramp-up time increases and skilled operators are required
Solution Approach 1:
The system automatically measures container dimensions and adjusts packing station components without human intervention. The control system receives measurement data and autonomously controls actuators to reposition packaging material components, eliminating the need for skilled operators to manually adjust settings during ramp-up
Solution Approach 2:
Manual mechanical adjustment by operators is replaced with an automated measurement and control system. Sensors measure container dimensions, and this data is transmitted to a control system that automatically actuates mechanical components to adjust the packing station, substituting human-operated mechanical systems with automated electro-mechanical systems
2Reliability
If manual adjustment of packaging material components is used when container dimensions deviate, then defective containers can be avoided, but trained operators must intervene leading to increased reject rates during adjustment periods
Solution Approach 1:
The system implements a closed-loop feedback mechanism where sensors continuously measure container dimensions, the control system processes this data to determine if adjustments are needed, and actuators automatically adjust the packaging material components accordingly. This continuous feedback loop ensures defective containers are avoided while maintaining high automation without requiring operator intervention
Solution Approach 2:
The packing station performs self-adjustment based on real-time container measurements. When dimensional deviations are detected, the system autonomously repositions packaging material components to match the container dimensions, eliminating the need for human operators to intervene and prevent defective packaging
3Measurement precision
If container dimension measurement is implemented without automatic adjustment, then dimensional deviations can be detected, but manual readjustment is still required increasing operational complexity
Solution Approach 1:
The measurement system and adjustment mechanism are merged into an integrated automated system. The control system combines sensor data acquisition, dimensional analysis, and actuator control into a unified system that automatically translates measurements into component adjustments, eliminating the need for separate manual intervention steps and reducing overall operational complexity

AI summary
In an installation (A) for the treatment of containers (B), having at least one filling station (F) and a packing station (P) that processes film or blank-form packing material (FP, ZP) and has working components that act on the packing material and form packages, at least one measuring device (M1, M2) for determining dimensional deviations of filled containers (B), and a controller (CU) for automatically adjusting at least one installation station depending on a determined dimensional deviation, working components that act on the packing material (FP, ZP) during the packaging of the filled containers (B) are automatically adjustable in the packing station (P) via the controller (CU). In a method for packaging filled containers, working components of the packing station that act on packing material (FP, ZP) are adjusted automatically depending on measured dimensional deviations, in order to form packages of different dimensions with at least substantially the same packing density.
