Unloading Vehicle Cover Handling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for unloading containers filled with bulk materials, especially those that are moisture-sensitive or prone to being blown away, require significant manipulation effort due to the need for tarpaulin systems or separate handling of container covers, which complicates the unloading process.
Innovation Solution
An unloading vehicle with a rotatable frame and a carrier system that includes a receiving device capable of vertically adjusting and pivoting to grasp and lift the container cover, allowing for simultaneous manipulation of the container and its cover without prior removal, using fork arms or electromagnets for secure handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tarpaulin system or separate handling of container covers is used, then the container can be protected during transport, but the manipulation effort and time required for unloading increases significantly
Solution Approach 1:
The patent combines the container and its cover into a single manipulated unit by providing a receiving device on the upper carrier that can grasp the cover simultaneously with the container bottom. This merging eliminates the need for separate handling operations, reducing manipulation effort while maintaining protection during transport.
Solution Approach 2:
The unloading vehicle is designed with multi-functionality to handle both the container and its cover using the same vehicle system. The upper carrier with the receiving device can grasp the cover, and the entire assembly can be manipulated, lifted, and rotated as one unit, making the vehicle universal for both container and cover handling.
2Reliability
If the container and cover are handled separately, then the cover can be secured during transport, but the unloading process becomes more complex and time-consuming
Solution Approach 1:
By merging the container and cover into a single manipulated unit through the receiving device that grasps the cover while the carrier holds the container bottom, the patent enables simultaneous handling of both components. This eliminates sequential operations and significantly increases unloading speed while maintaining cover security during transport.
3Device complexity
If a fixed structure is used for container handling, then the structure is simple, but it cannot accommodate the additional manipulation requirements of covering and uncovering operations
Solution Approach 1:
The patent introduces dynamic elements to the handling structure by providing an upper carrier that can be vertically adjusted in height and pivoted up and down relative to the frame. This dynamic structure adapts to different manipulation requirements including grasping the cover, lifting it, and performing uncovering operations, while maintaining overall structural simplicity.
Solution Approach 2:
The handling system is segmented into a lower carrier for container bottom handling and an upper carrier for cover handling. This segmentation allows each component to be optimized for its specific function while working together as an integrated system, providing both simplicity and adaptability.

AI summary
The vehicle (12) has a carrier (16) provided with a fork arm (17) and rotatably supported at a frame around an axis running horizontal and parallel to the fork arm. Another carrier (18) is provided above the carrier (16). The carrier (18) comprises a receiving device i.e. fork arm (19), for detecting a cover of a container, and is vertically height adjustable and/or pivotable upwards and downwards against the frame. The frame comprises upper and lower frame parts (15a, 15b), and the receiving device comprises an electro magnet at a lower side. An independent claim is also included for a combination of an unloading vehicle with a container cover.
