Solution Overview
Problem
Existing packaging devices face issues with cardboard outer packaging alignment and stability, leading to unstable packaging units and potential blockages due to misaligned or defective packaging, which requires user intervention to remove defects and interrupt the packaging process.
Innovation Solution
A packaging device with a horizontal conveyor and a feed device that introduces flat packaging blanks into the transport path, using optical detection and a pivoting transport device to separate defective packaging blanks and maintain process continuity, allowing for automatic defect recognition and sorting into collection containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cardboard outer packaging is supplied via a carton feeder, then packaging speed is improved, but packaging reliability deteriorates due to misalignment and defects
Solution Approach 1:
The patent applies preliminary action by inspecting cardboard outer packaging for defects and misalignments before they reach the horizontal conveyor. The detection device examines packaging blanks in advance, and the rejection device removes defective items before they can cause packaging failures, thus maintaining high productivity while improving reliability.
Solution Approach 2:
The patent implements feedback through a control device that receives signals from the detection device about packaging defects. Based on this feedback, the control device activates the rejection device to remove defective packaging, creating a closed-loop system that continuously maintains packaging quality without interrupting the overall process.
2Reliability
If defective packaging is removed by user intervention, then packaging quality is improved, but productivity deteriorates due to process interruption
Solution Approach 1:
The patent applies self-service by automating the detection and rejection of defective packaging through a detection device and rejection device. The system autonomously identifies and removes defective packaging blanks without requiring user intervention, thereby maintaining packaging quality while preventing process interruptions and preserving productivity.
Solution Approach 2:
The patent replaces the manual mechanical action of user intervention with an automated detection and rejection system. The detection device uses optical or sensing mechanisms to identify defects, and the rejection device mechanically removes defective packaging, substituting human labor with automated machinery to eliminate process interruptions.
3Productivity
If packaging blanks are continuously supplied, then productivity is improved, but stability deteriorates due to defective blanks causing blockages
Solution Approach 1:
The patent applies preliminary action by detecting and removing defective packaging blanks before they can cause blockages in the continuous packaging process. The detection device examines each blank in advance, and the rejection device eliminates defects proactively, enabling continuous operation without interruptions and maintaining process stability.
Solution Approach 2:
The patent implements beforehand cushioning by preparing for potential defects through continuous detection and rejection mechanisms. The system anticipates possible packaging failures by maintaining constant monitoring and readiness to remove defective blanks, thus cushioning against future disruptions and ensuring stable continuous operation.
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
The solution ensures reduced user intervention by automatically detecting and ejecting defective packaging blanks, maintaining packaging process efficiency and stability, and allowing flawless packaging blanks to be used continuously, thus improving logistical manageability and reducing production interruptions.
Implementation Method 1
In an inspection area, it is determined by means of an optical detection device whether any of the packaging blanks intended for insertion into the transport path have a defect
