Solution Overview

Problem

Existing transport devices struggle with efficiently dividing and managing mass flows of articles into individual lanes, particularly in packaging machines, due to issues like blockages caused by unevenly positioned or damaged articles, which can lead to disruptions and machine downtime, especially when dealing with non-circular based articles and plastic containers that stick together.

Innovation Solution

A transport device equipped with adjustable aisle plates and detection systems, including sensors and handling devices, to identify and rectify blockages by recognizing articles with reduced transport speed, irregular footprints, or those blocking lanes, and automatically reposition or remove them to maintain flow, using a combination of sensors and a handling device that can grasp and move articles to clear obstructions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If articles are transported in mass flow and divided into individual lanes using lane plates, then throughput and processing efficiency are improved, but blockages occur when articles are not properly positioned or get stuck on lane plates

Engineering Contradiction:
ImprovethroughputVSAvoidconveyance continuity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The detection device scans articles in the mass flow before they reach the lane division point to identify improperly positioned articles. The handling device then removes or repositions these articles in advance, preventing blockages at the lane plates and ensuring continuous conveyance while maintaining high throughput

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The detection device continuously monitors article positions in real-time and provides feedback to the handling device. When an article is detected to be improperly positioned or likely to block a lane, the system responds by automatically removing or repositioning the article, creating a closed-loop control system that maintains conveyance reliability

Inventive Principle:
Principle #23Feedback

2Reliability

If known detection devices are used to monitor container feeding, then disruptions can be detected, but the devices must be adapted or converted when container size changes

Engineering Contradiction:
Improvedisruption detectionVSAvoidcontainer size adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The detection device is designed with adjustable parameters and a universal detection mechanism that can accommodate different container sizes, shapes, and types. The system uses configurable detection thresholds and adaptable scanning patterns, allowing it to function effectively across multiple container variants without requiring hardware changes or complex reconfiguration

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The detection device incorporates dynamic adjustment capabilities where detection parameters such as sensitivity thresholds, scanning speeds, and evaluation criteria can be automatically or manually adjusted based on the specific container being processed. This dynamic adaptability allows the system to maintain reliable disruption detection across varying container specifications

Inventive Principle:
Principle #15Dynamics
