Engineering Contradiction Analysis
1Ease of operation
If print timing is determined through trial and error methods, then printing can be performed on continuously conveyed film, but the setting process becomes time-consuming and productivity decreases
Solution Approach 1:
The system pre-calculates and stores optimal print timing values based on bag information (length, weight, filling speed) before actual printing operations. This preliminary calculation eliminates the need for trial-and-error adjustments during production, allowing operators to directly apply pre-determined timing values and significantly reducing setup time.
Solution Approach 2:
The system incorporates a feedback mechanism where the actual printing results and bag information are continuously monitored. The print timing presentation unit compares actual performance with predicted values and automatically adjusts timing parameters, creating a closed-loop control system that continuously optimizes print timing without manual intervention.
2Manufacturing precision
If film feeding speed is adjusted to synchronize with printing, then optimal print positioning can be achieved, but the adjustment process requires repeated trial and error
Solution Approach 1:
The print timing presentation unit serves as an intermediary that translates bag information into optimal print timing and feeding speed parameters. Rather than directly coordinating between the printing unit and film conveying mechanisms, this intermediate component calculates and provides the synchronization parameters, simplifying the control architecture while achieving precise print positioning.
Solution Approach 2:
The system dynamically adjusts feeding speed parameters based on bag information such as length and weight. By changing the feeding speed parameter in response to different bag characteristics, the system maintains optimal print positioning accuracy across varying production conditions without requiring complex mechanical adjustments.
