Production Line Item Identification via Group Barcode Sequencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control systems for production/distribution lines are inadequate for real-time item identification, especially on high-speed lines where items are transported grouped, leading to issues with item loss and fraudulent interception, as they fail to accurately account for and track individual items within batches.
Innovation Solution
A method and system that utilize a controller with processing means to read and extract unique item identifiers from items arranged in a specific disposition, allowing for precise identification and detection of damaged items by sequencing the identifiers according to their positions within a group, using cameras and image processing to read barcodes or identifiers within digital images of batches or groups of items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional control systems are used on high-speed production lines where items are transported grouped, then productivity is improved, but measurement precision of individual items deteriorates
Solution Approach 1:
The system divides the identification process into two stages: first, group-level identification is performed on batches of items transported together, and second, individual item identification is extracted from the group data. This segmentation allows high-speed group transport while maintaining accurate individual item tracking through sequential processing of group and individual identifiers.
2Productivity
If items are transported in groups to improve productivity, then productivity is improved, but reliability of item tracking deteriorates due to item loss and fraudulent interception
Solution Approach 1:
The system implements a feedback mechanism where the controller compares the list of identified items from the group against the items that should have been collected in the batch. This verification process detects discrepancies such as missing items or fraudulent interceptions, providing feedback that ensures reliable tracking even when items are transported in groups for improved productivity.
3Measurement precision
If conventional readers read identifiers sequentially on single-file items, then measurement precision is maintained, but productivity deteriorates due to inability to handle grouped items efficiently
Solution Approach 1:
The system merges the reading operations for multiple items into a single group-level identification process. Instead of sequentially reading each item's identifier one by one, the controller reads a group identifier that represents multiple items simultaneously, then extracts individual item identifiers from this group data. This merging approach maintains measurement precision while dramatically improving productivity by handling batches of items in parallel rather than sequentially.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables robust real-time control and accurate identification of items on high-speed production/distribution lines, ensuring that all items are accounted for and reducing errors, even when items are transported in groups, by maintaining a list of item identification data and associating it with batch packaging data for reliable tracking and tracing.
Implementation Method 1
read identifiers from light reflected or emitted by said identifier within any optical wavelength range between the UV (ultraviolet) and the IR (infrared)
Data Source
AI summary
The disclosed method, and corresponding system, for controlling items on a production/ distribution line relies on secure identification of items transported arranged in a given disposition along a transport path at a site of collection and packaging of the items, and association of ID data of some of the packed items with corresponding packaging ID data so as to ensure reliable identification of package content delivered on the line.
