Vacuum Suction System for Package Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic equipment for unloading packages from roll box pallets in logistics requires manual handling, leading to increased physical and mental burden on workers due to the need for precise and quick handling of variously sized packages, which is not efficiently automated.
Innovation Solution
The transfer equipment employs a vacuum suction system with multiple vacuum suction pads and a control system that uses negative pressure to securely hold packages, along with image sensors and a controller to determine the vacuum suction state, allowing for efficient and stable transfer of packages without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling is used for unloading packages, then workers can handle variously sized packages with flexibility, but workers experience increased physical and mental burden and handling efficiency is reduced
Solution Approach 1:
The system uses image sensors to automatically detect package dimensions and the controller automatically selects and adjusts the number of vacuum suction pads needed, enabling the system to serve itself without manual intervention for each package
Solution Approach 2:
The controller dynamically changes the operational parameters by adjusting the number of activated vacuum suction pads based on the detected package size, optimizing the holding force for each specific package dimension
2Adaptability or versatility
If multiple vacuum suction pads are used to handle variously sized packages, then the system can adapt to different package dimensions, but determining the vacuum suction state becomes more complex
Solution Approach 1:
The system incorporates pressure sensors that provide real-time feedback on the vacuum suction state of each pad, allowing the controller to monitor and adjust the holding state based on actual pressure readings from all activated pads
Solution Approach 2:
The system replaces complex mechanical determination methods with sensor-based detection, using image sensors to detect package dimensions and pressure sensors to detect vacuum suction states, converting mechanical problems into measurable physical quantities
3Force
If the number of vacuum suction pads is increased to handle larger packages, then the holding capacity is improved, but the system complexity and control difficulty increase
Solution Approach 1:
The system dynamically adjusts the number of active vacuum suction pads based on real-time package dimension detection, allowing the holding capacity to be optimized for each package size without permanently increasing system complexity
Solution Approach 2:
The vacuum suction system is divided into multiple independently controllable pads, allowing the controller to activate only the necessary number of pads for each package size, managing complexity through modular control
