Tube Dispensing Line Defect Isolation With Vision Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automated production systems, identifying and isolating defective units in dispensing, capping, and labeling processes is time-consuming and inefficient, leading to increased error rates and reduced throughput.
Innovation Solution
An automated production system with integrated vision inspection devices and defect product boxes that isolate defective tubes by releasing them to specific spaces, allowing operators to quickly identify and repair failed units, thereby reducing error rates and maintaining system efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple units are used to increase process throughput, then productivity is improved, but difficulty of detecting and measuring failures increases
Solution Approach 1:
The system segments the production line into multiple independently inspectable units. Each unit has its own vision inspection device that inspects processed products and identifies failures specific to that unit. This segmentation allows operators to quickly identify which specific unit has failed without having to check all units manually, thus maintaining high productivity while improving failure detection efficiency.
Solution Approach 2:
The vision inspection devices provide immediate feedback about product quality and unit performance. When a defect is detected, the system provides real-time information about the specific unit responsible, enabling rapid response and maintenance decisions. This feedback mechanism ensures that failures in multi-unit systems are detected and identified efficiently.
2Measurement precision
If visual inspection of all tubes is performed to find defects, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The vision inspection devices perform preliminary automated inspection of products as they pass through each processing unit. This preliminary action captures defect information before the products move to subsequent units, eliminating the need for final comprehensive manual inspection. The system inspects each product at the point of processing, ensuring accurate defect detection while minimizing total inspection time.
Solution Approach 2:
The system replaces manual visual inspection with automated vision inspection devices. These devices use optical sensors and image processing algorithms to detect defects automatically, providing measurement precision comparable to or exceeding human inspection while dramatically reducing the time required. The automated system can inspect multiple products simultaneously and continuously without fatigue.
3Productivity
If defective products are not isolated, then productivity is maintained, but reliability deteriorates
Solution Approach 1:
The system extracts defective products from the continuous production flow using automated rejection mechanisms. When the vision inspection device detects a defect, the system automatically removes the defective product from the conveyor line, preventing it from reaching subsequent processing units or customers. This extraction maintains continuous production of good products while ensuring defective products are reliably identified and removed.

AI summary
This production automation system for handling tubes in which a solution can be accommodated, a body capped with a lid being defined as a tube, may comprise: a first supply device for grouping bodies or tubes into groups of at least two and supplying the plurality of groups of bodies or the plurality of groups of tubes; a dispensing device including dispensing units, each unit dispensing, in a single dispensing process step, the solution to each body of one group among the plurality of groups of bodies; a first vision inspection device for inspecting, in a single defective dispensing inspection process step, whether the dispensing of the solution accommodated in each body of one group is defective; a first defect product box including a number of defective dispensing spaces, the number of defective dispensing spaces being the same as the number of dispensing units; a transfer device for holding each tube of one group and transferring the one group of tubes; and a control unit for controlling the transfer device so that a tube with defective dispensing, among the one group of tubes inspected by the first vision inspection device, is discharged into a preset defective dispensing space among the defective dispensing spaces.
