Bag Packaging Inspection via Preliminary Analysis Station
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The closed portions of individual bags tend to be directed in undesired directions when the bag is closed and separated, making subsequent inspection using vision technology difficult.
Innovation Solution
A system comprising a station for converting a sheet-shaped material into a partly closed bag, a closing station for closing the bag, a separating station for separating the closed bag from the sheet material, and an analysing station positioned between the closing and separating stations to analyse the closed bag before separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the bag is closed and separated immediately, then the production speed is maintained, but the closed portion is directed in undesired directions making inspection difficult
Solution Approach 1:
The analysing station is positioned between the closing station and the separating station to perform inspection of the closed bag before separation occurs. This preliminary action allows the closed portion to be properly oriented and inspected while still connected to the sheet material, avoiding the orientation problems that occur after separation.
Solution Approach 2:
The patent introduces an intermediary analysing station that acts as a mediator between the closing and separating operations. This station provides a controlled environment for inspection where the bag can be properly positioned and examined before the separation action disrupts its orientation.
2Productivity
If the bag is separated immediately after closing, then the process efficiency is maintained, but the quality inspection of the closed portion becomes difficult
Solution Approach 1:
The inspection is performed as a preliminary action before the separating station divides the bag from the sheet material. This timing ensures that the closed portion maintains its proper orientation and can be accurately inspected for quality without the complications introduced by separation.
Solution Approach 2:
The analysing station provides feedback on the quality of the closed portion before separation occurs. This feedback mechanism allows for real-time quality control while the bag is still in a controllable position, enabling immediate detection and correction of any closure defects.
3Measurement precision
If the analysing station is positioned after the separating station, then the inspection can be performed on individual bags, but the closed portion is directed in undesired directions
Solution Approach 1:
The analysing station is strategically positioned to perform inspection before the separating station alters the orientation of the closed portion. This preliminary inspection captures the closed portion in its proper orientation, ensuring both accurate measurement and correct shape/orientation are maintained.
Solution Approach 2:
The analysing station serves as an intermediary between closing and separating operations, providing a stable inspection point where the closed portion maintains its intended orientation. This intermediary position prevents the orientation problems that would occur if inspection were performed after separation.
