Container Handling Signals for Planned Type Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Container treatment systems face challenges in minimizing adjustment and changeover times, leading to increased downtime and costs, particularly due to the need for timely preparation and execution of changes in container types and products.
Innovation Solution
A container treatment system with a type preselection memory and output devices that emit audio and optical signals to remind operators of impending changes or refills, allowing for early preparation and reducing waiting times by signaling planned states distinct from disruptions or dangers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If operators manually monitor and prepare for type changes without automated signals, then the system structure remains simple, but setup and changeover times increase due to delayed preparation
Solution Approach 1:
The system performs preliminary actions by detecting when container stocks are running low and automatically signaling operators in advance before actual depletion occurs. This advance notification allows operators to prepare for type changes proactively, reducing actual changeover time while maintaining manageable system complexity through automated monitoring and signaling.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring container stock levels and providing automated signals to operators when refilling or type changes are needed. This feedback loop eliminates manual monitoring delays and enables timely preparation for changeovers, resolving the contradiction between reduced changeover time and system complexity.
2Productivity
If the system uses automated detection and signaling for planned states, then changeover preparation time is reduced, but the complexity of control and signaling systems increases
Solution Approach 1:
The system performs preliminary detection of low container stocks and signals operators in advance, enabling proactive preparation for type changes. This preliminary action increases plant availability by preventing unplanned stoppages, while the automated detection and signaling infrastructure, though adding some complexity, remains manageable through standardized components and clear signal protocols.

AI summary
A container handling plant (1; 2) and a method for a container handling plant (1; 2) are shown. The container handling plant (1; 2) comprises at least one container handling machine (10, 20, 30, 40) for handling containers (5), wherein at least one container handling machine (10, 30, 40) has a type preselection memory (11, 31, 41) in which it is possible to preselect different types (111, 112; 311, 312, 313; 411, 412) for handling to be carried out by the container handling machine (10, 30, 40), at least one output device (15, 35, 45, 16, 36, 46) which is arranged on the at least one container handling machine (10, 30, 40) and is intended to output an audio signal (TS1, TS2, TS3) and/or an optical signal (OS1, OS2, OS3), and a control device (60) which is configured to control the at least one output device (15, 35, 45, 16, 36, 46) in such a manner that the output device acoustically outputs a predetermined audio signal (TS1, TS2, TS3) comprising tone sequences with at least two different tones and/or optically outputs an optical signal (OS1, OS2, OS3) if, on account of the type (111, 112; 311, 312, 313; 411 412) preselected in the type preselection memory (11, 31, 41), a change of a type (111, 112; 311, 312, 313; 411, 412) or refilling for the preselected type (111, 112; 311, 312, 313; 411, 412) is imminent in the future on the container handling machine (10, 20, 30, 40) after expiry of a predetermined period.
