Palletizing Restart Guidance for Defective Bag Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing palletizing devices face challenges in efficiently restarting after unplanned or emergency stops due to incorrectly oriented or defective bags, leading to complex and costly manual intervention to maintain the layer pattern.
Innovation Solution
A method and device that utilizes a control device to display which bags need to be removed or retained on a display device, allowing for semi-automatic or automatic correction of bag orientation and position to maintain the layer pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual intervention is used to remove defective bags and restore layer pattern after unplanned stop, then the palletizing process can be restarted, but the operation becomes time-consuming and complex
Solution Approach 1:
The system implements feedback by detecting defective bags during conveyance and providing real-time information to the control device. The control device then guides the user through the necessary removal actions, creating a closed-loop system that reduces restart time while maintaining reliability.
Solution Approach 2:
The control device acts as an intermediary between the detection system and the user. It processes detection data, determines the appropriate layer pattern restoration actions, and presents guided instructions to the user, simplifying the complex manual intervention process.
2Manufacturing precision
If complete manual inspection and removal of defective bags is performed to maintain layer pattern, then pattern accuracy is maintained, but operational complexity and cost increase
Solution Approach 1:
The system performs self-service by automatically detecting defective bags and determining the necessary corrections to maintain layer pattern accuracy. The control device autonomously calculates which bags need removal and in what sequence, reducing the need for complex manual inspection procedures.
Solution Approach 2:
The system takes preliminary action by identifying defective bags before they disrupt the layer pattern formation. The control device pre-calculates the restoration sequence, allowing the user to simply follow guided steps rather than performing complex manual inspections and decisions.
3Ease of operation
If user manually determines which bags to remove after unplanned stop, then flexibility is maintained, but error-prone decisions may disrupt layer pattern
Solution Approach 1:
The control device provides feedback to the user by presenting information about which bags are defective and should be removed. This feedback loop guides user decisions, maintaining ease of operation while ensuring pattern maintenance reliability through informed, systematic decision-making.
Solution Approach 2:
The system replaces complex mechanical decision-making processes with an automated control system that uses detection data to determine bag removal sequences. This substitution reduces user error while maintaining operational simplicity through guided instructions.
