Pivoting Container Lift With Agitator for Complete Unloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container unloading systems are inefficient and cumbersome due to the heavy and unwieldy nature of containers, requiring specialized loaders and unloaders, and lack flexibility in handling containers of varying dimensions.
Innovation Solution
A container unloading apparatus with a pivotally coupled lift and door system, controlled by a controller, that transitions between loading and emptying positions, featuring a bale and conveyor system to facilitate the unloading of containers of varying sizes, and optional agitators to ensure complete discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If specialized loaders and unloaders are used to handle heavy containers, then the container unloading function is achieved, but the device complexity increases and operational efficiency decreases
Solution Approach 1:
The patent combines the loading and unloading functions into a single integrated apparatus. The lift mechanism serves dual purposes: it loads containers onto the platform and subsequently unloads them by tilting, eliminating the need for separate specialized loaders and unloaders, thus reducing device complexity while maintaining productivity
Solution Approach 2:
The apparatus is designed with multi-functionality where the same structural components perform multiple operations. The platform, lift mechanism, and tilting system work together to both load and unload various container types, making the device versatile and reducing overall system complexity
2Adaptability or versatility
If fixed-dimensional container handling systems are used, then the system structure is simplified, but the adaptability to containers of varying dimensions is reduced
Solution Approach 1:
The patent incorporates dynamic adjustability in the platform and lift mechanism to accommodate containers of different dimensions. The platform can be adjusted in position and the lift mechanism can accommodate varying container heights and weights, providing adaptability without requiring completely different systems for each container type
Solution Approach 2:
The system allows for parameter changes in container size, weight, and dimensions while maintaining the same fundamental apparatus. The adjustable platform position and lift capacity parameters enable the handling of diverse container specifications without increasing overall device complexity
3Loss of time
If manual container handling is used, then the equipment cost is reduced, but the operational time and labor effort increase significantly
Solution Approach 1:
The patent replaces manual mechanical handling with an automated mechanical system featuring powered lift mechanisms and controlled tilting. This substitution reduces the time required for container operations while maintaining ease of operation through centralized control, eliminating the need for extensive manual labor

AI summary
An apparatus for emptying the contents of a container. The apparatus may include a base and a lift coupled to the base and movable between a loading position and emptying position. In some embodiments, the apparatus may include a lift actuator including a lift piston configured to move the lift from the loading position to an intermediate position and a rotation piston for moving the lift from the intermediate position to the emptying position. In some embodiments, the apparatus includes a frame, a platform, a mast, and a bale. The bale is slidably disposed on the mast for selectively adjusting the distance between the bale and the platform. In some embodiments, a lift may be provided with an agitator to release interlocked packages and allow them to empty from a container in an emptying position. The agitator may include an airbag and a spring pack on opposite sides of the platform.
