Picking Device Strapping Mechanism for Layer Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for picking goods carriers, such as pallets, struggle to securely handle and manage loading layers, especially for sensitive items like fruits and vegetables, and prevent falling or slipping during the picking process, particularly when transitioning between loading layers.
Innovation Solution
A device with a strapping mechanism arranged above, inside, or below the picking stage, which secures loading layers immediately after completion and lowering, ensuring stability and preventing slipping or falling, allowing for high-speed picking and reliable handling of sensitive goods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a strapping device is installed to secure loading layers during order picking, then goods stability and prevention of falling/slipping is improved, but device complexity increases
Solution Approach 1:
The strapping device is integrated within the picking chute structure, nesting the strapping function inside the existing picking station framework. This allows the strapping mechanism to be housed within the chute without requiring separate external equipment, thereby improving goods stability while minimizing the increase in overall device complexity.
Solution Approach 2:
The picking chute is designed to serve multiple functions: it guides the goods carrier, contains the strapping device, and provides structural support for the strapping operation. By making the chute multi-functional, the patent avoids adding separate dedicated structures for strapping, thus improving reliability without proportionally increasing device complexity.
2Ease of operation
If the strapping device is positioned above the picking platform, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The strapping device is positioned vertically above the picking platform, utilizing the vertical dimension rather than expanding horizontally. This allows the strapping mechanism to be integrated into the vertical profile of the picking chute, making it accessible and easy to operate from above while containing the structural requirements within the existing vertical envelope of the picking station.
3Reliability
If film wrapping is used to secure goods layers, then goods stability is improved, but adaptability to sensitive goods deteriorates
Solution Approach 1:
The patent changes the physical state and form of the securing mechanism from flexible film wrapping to rigid strapping bands. This parameter change allows the use of different securing methods (strapping vs. film) depending on the goods type, improving adaptability to sensitive goods that cannot be wrapped in film while maintaining goods stability through the strapping action.
