Foldable Crate Machine with Swivel Arms and Defect Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for opening and closing crates with foldable side walls are inefficient due to the need for manual adjustment and sorting of different crate models, lack of defective crate detection, and high downtime, especially when handling crates with varying dimensions and locking mechanisms.
Innovation Solution
A multi-station machine with a survey station for defect detection, an unfolding/closing station with adjustable conveyor mechanisms and articulated swivel arms for accommodating various crate sizes, and a stress test station for latching mechanisms, allowing for autonomous processing and sorting of defective crates, enabling efficient handling of diverse crate models without prior sorting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment and sorting of different crate models is performed, then the machine can handle various crate sizes, but the productivity decreases and downtime increases
Solution Approach 1:
The machine is designed with universal components that can handle multiple crate models without requiring manual reconfiguration. The articulated swivel arms and adjustable conveyor mechanisms are configured to accommodate various crate dimensions and locking mechanisms automatically, allowing a single machine to perform multiple functions across different crate types.
Solution Approach 2:
The machine incorporates dynamically adjustable components including articulated swivel arms with variable angles and conveyor belts with adjustable positions. These dynamic elements adapt automatically to different crate models during operation, eliminating the need for manual reconfiguration and maintaining continuous high-speed processing.
2Productivity
If defective crates are not detected and ejected, then the machine operates continuously, but the reliability of the process decreases due to functional interruptions
Solution Approach 1:
The machine incorporates a survey station that performs preliminary detection and assessment of crate conditions before the main unfolding process. Defective crates are identified and marked for ejection in advance, allowing the main processing line to continue operating without interruptions while maintaining high reliability through pre-screening.
Solution Approach 2:
The machine includes a feedback system where the survey station continuously monitors crate conditions and provides real-time information to the control system. This feedback enables automatic ejection of defective crates and adjustment of processing parameters, ensuring continuous reliable operation by preventing defects from disrupting the main process.
3Manufacturing precision
If specialized machines are used for specific crate models, then the manufacturing precision for each model is high, but the device complexity increases and adaptability decreases
Solution Approach 1:
Instead of specialized machines for each crate model, the invention employs a universal machine design with adjustable components that can accommodate multiple crate models. The articulated swivel arms, adjustable conveyors, and configurable locking mechanism interfaces provide the necessary manufacturing precision for various crate types without requiring separate specialized equipment for each model.
Solution Approach 2:
The machine maintains high manufacturing precision across different crate models by dynamically adjusting parameters such as swivel arm angles, conveyor positions, and locking mechanism forces. These parameter changes are automatically configured based on the detected crate model, allowing precise unfolding operations without increasing physical device complexity.
4Strength
If heavy pivoting arms with large dimensions are used for erecting side walls, then the structural strength is sufficient, but the speed of operation decreases due to mass inertia
Solution Approach 1:
The invention replaces heavy static pivoting arms with lighter articulated swivel arms that can dynamically adjust their movement characteristics. The articulated design with multiple joints allows the arms to optimize their moment of inertia during operation, enabling faster work cycles while maintaining sufficient structural strength through strategic placement of actuators and use of high-strength materials.
Solution Approach 2:
The machine uses pneumatic or hydraulic actuators to drive the swivel arms, providing high force output in short bursts that overcome the reduced mass inertia of the lighter arms. This allows the system to achieve both the necessary strength for erecting side walls and the high speed required for frequent work cycles, eliminating the trade-off present in mechanical lever systems.

AI summary
The machine has one or multiple expanding or collapsing stations (B,B1) provided for certain crate models. The defects and damages are detected at the crates in each of the stations, and a free space is provided at each station below the area of the passage (1v) of the crates.
