Multi-Mode Holding Apparatus for Stack Collapse Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article handling systems, such as depalletizing machines, face challenges in securely handling extremely heavy or paper-wrapped articles, as they often rely on suction methods that are inadequate for such items, leading to potential stack collapse during extraction.
Innovation Solution
The system incorporates a holding apparatus with a rotating, moving, and supporting mechanism that allows for multiple operation modes, including upper surface suction, side surface suction, and scrape-out modes, using suction pads and a moving mechanism to securely grasp and move articles, while a control apparatus determines the optimal operation mode based on sensor data to prevent stack collapse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If suction method is used to hold articles, then the handling process is simple, but it cannot securely hold extremely heavy articles or articles wrapped in paper
Solution Approach 1:
The holding apparatus is designed to perform multiple holding functions: suction holding for light articles, mechanical clamping for heavy articles, and support from below for paper-wrapped articles. This multi-functional design allows a single apparatus to handle diverse article types securely without requiring separate handling systems for different article categories.
2Reliability
If multiple operation modes are added to handle different article types, then holding capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple holding mechanisms (suction pads, clamping arms, support structures) into a single integrated holding apparatus. The control apparatus automatically selects and coordinates the appropriate holding mode based on article characteristics, achieving multiple functions without requiring separate handling systems for different article types.
Solution Approach 2:
The control apparatus automatically determines the appropriate holding mode by detecting article characteristics such as weight, shape, and wrapping material. This self-service capability eliminates the need for manual intervention or complex mechanical switches between modes, reducing operational complexity while maintaining multi-functional holding capability.
3Reliability
If suction force is increased to hold heavy articles, then holding capability is improved, but risk of stack collapse increases
Solution Approach 1:
The holding apparatus applies different holding forces and methods to different parts of the article based on its characteristics. For heavy articles, mechanical clamping provides localized secure holding without requiring excessive suction force that could destabilize the stack. For paper-wrapped articles, support from below distributes the load evenly, preventing localized stress that could cause stack collapse.
