Package Printing Queue Synchronization for Out-of-Sequence Labeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing systems struggle with accurately matching the sequence of printed labels to packages when there are discrepancies in loading sequences, leading to potential mislabeling and requiring additional quality checks and corrective measures.
Innovation Solution
A system and method that utilizes a barcode sensor and control system to read unique identifiers on packages, synchronize print commands with package movement, and manage print queues to ensure correct labeling even when packages arrive out of sequence, using inkjet printing technology to apply customized content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If packages are loaded onto the conveying system in a fixed sequence with pre-generated labels, then the labeling process is efficient and automated, but sequence disruptions cause mislabeling requiring quality checks and corrective measures
Solution Approach 1:
The system dynamically adjusts the labeling process by reading barcodes on packages in real-time and retrieving corresponding print data from storage based on actual package identification rather than relying on fixed sequence positioning. This allows the system to adapt to sequence disruptions while maintaining accurate label-package matching.
Solution Approach 2:
The system implements feedback by using barcode sensors to read package identifiers, comparing them against stored print data sequences, and automatically retrieving the correct label data when mismatches are detected. This closed-loop feedback mechanism ensures accurate labeling even when package sequences are disrupted.
2Reliability
If quality checks are implemented to verify correct label-package matching, then labeling accuracy is improved, but production time and system complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-storing print data for multiple packages in a database with their corresponding barcode identifiers before the labeling process begins. This allows the system to quickly retrieve and verify correct label data without requiring time-consuming quality checks during production, as the matching logic is already prepared in advance.
3Reliability
If corrective measures are implemented to generate additional labels for mislabeled packages, then labeling accuracy is restored, but material waste and processing time increase
Solution Approach 1:
The system performs self-service by automatically detecting sequence disruptions through barcode reading, retrieving the correct print data from storage, and applying the appropriate label without requiring external quality checks or corrective interventions. This autonomous operation prevents mislabeling before it occurs, eliminating the need for corrective measures and associated material waste.

AI summary
A method and system printing includes transporting an object toward a print system. A plurality of blocks of print commands is stored in an ordered sequence in a first queue and a first identifier encoded in indicia on an object is received. An oldest block of print commands from the stored plurality of blocks is selected, wherein the oldest block of commands is associated with a second identifier. If the first identifier is associated with a second identifier, the print system is operated to printing content specified by the selected block of print commands on the object. Otherwise, the oldest block is stored in a second queue.
