Container Handling Plant Retroactive Fault Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional container handling systems face significant wastage due to downstream errors, such as defective valves in filling machines, leading to unnecessary production and sterilization of containers, as well as incorrect filling of beverages.
Innovation Solution
A device with a state-recognition system and control unit that identifies atypical states in handling elements or containers, allowing for the interruption of container supply to prevent further processing by faulty units, thereby reducing material loss by diverting or separating affected containers before they reach the faulty station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional container handling systems operate continuously without interruption, then productivity is maintained, but material wastage increases due to defective downstream handling elements
Solution Approach 1:
The system performs preliminary detection of defective handling elements before they can cause widespread material wastage. By monitoring the operational state of handling elements and identifying defects in advance, the system can take preventive actions to stop containers from being processed by defective elements, thus resolving the contradiction between continuous operation and material wastage.
Solution Approach 2:
The system implements feedback mechanisms where the state of handling elements is continuously monitored and fed back to the control system. This feedback loop enables real-time identification of defective elements and automatic adjustment of container flow, allowing the system to maintain productivity while minimizing material wastage by directing containers away from defective handling elements.
2Productivity
If containers are processed through all handling units including defective ones, then production throughput is maintained, but unnecessary sterilization and filling occurs causing material loss
Solution Approach 1:
The system extracts or removes containers from the production flow before they reach defective handling elements. By identifying defective handling elements and selectively diverting containers away from these points, the system prevents unnecessary sterilization and filling operations, thereby reducing material wastage while maintaining overall production throughput.
Solution Approach 2:
The system takes preliminary action by detecting defective handling elements before containers reach them. This advance detection allows the system to prevent containers from entering defective handling zones, avoiding unnecessary processing steps like sterilization and filling, thus reducing material loss while preserving production efficiency.
3Device complexity
If downstream handling elements are not monitored, then device complexity is low, but significant wastage occurs due to un detected defects
Solution Approach 1:
The system introduces feedback mechanisms that monitor the operational state of downstream handling elements and provide real-time information to the control system. This feedback enables the system to detect defects and adjust container flow accordingly, preventing wastage while adding only necessary monitoring complexity to achieve effective defect detection.
Solution Approach 2:
The monitoring system is designed to self-identify and report defective handling elements without requiring complex external intervention. By enabling the system to automatically detect and communicate the status of handling elements, the solution reduces the need for overly complex monitoring infrastructure while effectively preventing material wastage through autonomous defect detection.
4Productivity
If defective handling elements continue to operate, then productivity is maintained, but incorrect filling and processing occurs leading to waste
Solution Approach 1:
The system implements feedback mechanisms that continuously monitor the operational state of handling elements and provide real-time information to the control system. This feedback enables the system to detect defects in handling elements that affect filling accuracy and automatically adjust container flow to prevent incorrect filling, thus maintaining both productivity and manufacturing precision.
Solution Approach 2:
The system performs preliminary detection of handling element defects before they can cause incorrect filling or processing. By identifying potential issues in advance and taking preventive action to divert containers away from defective elements, the system maintains filling accuracy and operational continuity without allowing defective handling to occur.

AI summary
A device and a method for the handling of containers with a plurality of handling units. A defective state in a handling element situated downstream can be recognized and as a reaction to this recognition a specified container conveyed upstream can be separated out, namely preferably that container which in the further operating sequence would arrive at the handling element known to be operating defectively.
