Solution Overview
Problem
Existing packaging machines require complex and time-consuming setup by skilled operators, leading to inefficiencies and reduced performance due to inflexible time-controlled processes, which can result in substantial time delays and reduced production capacity.
Innovation Solution
A self-controlling packaging machine equipped with an intelligent sensor system and control technique that monitors actual process values and adapts program sequences in real-time, allowing for sensor-controlled operation independent of preset times, enabling better coordination and optimization of production processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If time-controlled processes are used with preset schedules, then process coordination is achieved, but operator skill requirement increases and setup time increases
Solution Approach 1:
The packaging machine automatically determines process times and coordinates individual processes without operator intervention. The control unit monitors actual process values and autonomously adjusts timing parameters, eliminating the need for skilled operators to manually preset complex time schedules while maintaining reliable process coordination.
2Reliability
If time-controlled processes are used with preset schedules, then process coordination is achieved, but productivity decreases due to time delays
Solution Approach 1:
The system dynamically adjusts process timing based on actual process values rather than following fixed preset schedules. The control unit continuously monitors parameters such as heating temperature, pressure, and vacuum levels, and automatically modifies process durations to eliminate unnecessary time delays while ensuring proper process coordination, thereby increasing productivity.
Solution Approach 2:
The control unit receives feedback from sensors monitoring actual process values during operation. Based on this feedback, the system automatically adjusts timing parameters to optimize process coordination and eliminate delays. This closed-loop control ensures that processes are coordinated efficiently without the time losses associated with rigid preset schedules.
3Reliability
If complex time presetting is required for each product, then process coordination is achieved, but ease of manufacture decreases
Solution Approach 1:
The packaging machine automatically determines and adjusts all timing parameters for different products without requiring manual presetting. When a product change occurs, the control unit autonomously retrieves appropriate process parameters and coordinates the individual processes, eliminating the complex setup work previously required while maintaining reliable process coordination.
Solution Approach 2:
The control unit is designed to handle multiple product types and automatically adapt timing parameters for each. The system stores and retrieves product-specific process parameters, enabling it to coordinate diverse packaging processes without requiring separate manual setup procedures for each product, thereby simplifying manufacturing operations.

AI summary
A packaging machine comprising a control unit, a plurality of measuring devices and a plurality of working units for different process. The control unit is functionally connected to the working units and to the measuring devices. The measuring devices may detect actual process values at the respective working units and forwarding these values to the control unit for monitoring the respective working units. The control unit may create a specific program sequence for each of the individual working units and/or a program sequence coordinated with respect to the working units, by comparing the actual process values from the respective measuring devices with associated target process values from a memory. The individual working units may function according to this program sequence, depending on the actual process values detected at these working units, and/or the working units are coordinated with one another based on the actual process values.
