Rotating Board Container for Automated Unloading and Piling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional board unloading devices face challenges such as difficulty in piling boards, sticking due to surface tension, and bending of thin boards, leading to operational stoppages and inefficiencies in surface treatment processes.
Innovation Solution
A board unloading device with a board dropper, carrier, and air sprayer that rotates the board container to prevent bending, uses cutouts to support the board, and sprays air to prevent sticking, enabling automated and smooth unloading of boards of varying sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If boards are unloaded manually into a container, then the unloading process is simple, but workers must pile boards manually which is troublesome and time-consuming
Solution Approach 1:
The board unloading device automatically performs the unloading and piling operations without manual intervention. The rotating container carries boards automatically after they are unloaded from the transport hanger, eliminating the need for workers to manually pile boards while maintaining simple operational procedures
Solution Approach 2:
The board container is designed to rotate dynamically after receiving boards. This rotation automatically transports boards from the unloading position to the piling position, transforming a static manual piling process into a dynamic automated system that improves productivity
2Productivity
If boards are dropped vertically into a container, then unloading is fast, but surface tension causes boards to stick to the container wall
Solution Approach 1:
The harmful effect of surface tension is eliminated by extracting boards from the container through a cutout opening rather than having them drop vertically along the container wall. The cutout allows boards to be removed at a specific position where sticking does not occur, separating the unloading function from the harmful contact with the container surface
Solution Approach 2:
The cutout opening acts as an intermediary mechanism that facilitates board removal without direct contact between the board and the container wall. This intermediate structure allows boards to pass through cleanly, preventing the adhesion caused by surface tension while maintaining rapid unloading
3Device complexity
If thin boards are unloaded without support, then the unloading process is simple, but the upper part of thin boards bends during unloading
Solution Approach 1:
The board container is preliminarily positioned with its bottom surface at an appropriate height before board unloading occurs. This preliminary positioning ensures that thin boards are properly supported during the unloading process, preventing bending while maintaining a simple device structure without requiring additional support mechanisms
4Device complexity
If the board container remains stationary, then the device structure is simple, but boards cannot be easily piled and transported
Solution Approach 1:
The board container is transformed from a stationary structure to a dynamic rotating component. This rotation enables automatic board transport from the unloading position to the piling position, facilitating easy board accumulation and subsequent removal while maintaining relatively simple device structure
Solution Approach 2:
The board container utilizes rotational motion in a different spatial dimension to achieve board transport and piling. Instead of linear movement mechanisms, the container rotates to convey boards horizontally, simplifying the overall device structure while improving operational ease for board accumulation and removal

AI summary
A board unloading device is provided that can simplify unloading task and can be used to unload and pile a thin board. A board dropper unlocks clamping of the board in fallen condition of a transport hanger. A board container receives and houses the board when the board has fallen vertically. By activating a rotate cylinder, the board container is rotated. A transport roller carries out the board horizontally from an open area of the rotated board container.
