Rotatable Unloading Vehicle for Simultaneous Container and Cover Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for unloading containers filled with bulk goods, especially those sensitive to moisture or prone to being blown off during transport, require significant effort in handling due to the need to remove and manage container covers separately.
Innovation Solution
A rotatable unloading vehicle with a vertically adjustable and swivellable carrier system that can engage and lift the container cover, allowing for simultaneous handling of the container and its cover without prior removal, using fork prongs or electromagnets for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a tarpaulin system is used to cover the container during transportation, then moisture-sensitive bulk goods are protected, but the handling effort increases considerably
Solution Approach 1:
The container cover is integrated with the container base to form a single unit. The cover is connected to the base via connection elements that allow the cover to be automatically positioned and secured during unloading operations, eliminating the need for separate tarpaulin handling
Solution Approach 2:
The container cover serves dual functions: it protects the bulk goods from moisture during transportation and can be automatically handled during unloading operations. The cover is designed to work with both protective and unloading functions through its integration with the base
2Ease of operation
If the container cover is removed in advance before unloading, then the handling process is simplified, but the time expenditure for handling increases
Solution Approach 1:
The cover is pre-integrated with the container base through connection elements that are prepared in advance. During unloading, the cover is automatically positioned and secured as part of the unloading process itself, eliminating the need for separate pre-removal or post-securing operations
Solution Approach 2:
The cover removal and container unloading operations are merged into a single integrated process. The cover remains attached to the base during transport but can be automatically detached and positioned during unloading, combining what were previously separate operations
3Object-affected harmful factors
If a fixed cover is used on the container, then protection during transport is improved, but the unloading process becomes more complex
Solution Approach 1:
The cover is designed with dynamic characteristics that allow it to transition from a fixed protective state during transport to a movable state during unloading. The connection elements enable the cover to be dynamically repositioned from covering the container to being held by the unloading vehicle
Solution Approach 2:
Connection elements serve as intermediaries between the cover and the container base. These elements facilitate the transition of the cover from a fixed protective structure to a movable component that can be handled by the unloading vehicle's carrier
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution significantly reduces the time and effort required for unloading by enabling the unloading vehicle to manage both the container and its cover, simplifying the emptying process and maintaining a stable construction for efficient operation.
Implementation Method 1
the receiving arrangement can be provided with electromagnets, in particular on its underside

AI summary
An unloading vehicle for the rotary unloading of a container, able to be covered by a fixed cover, which has a container base with two fork pockets, with a frame on which a carrier, provided with a pair of fork prongs, is mounted so as to be rotatable about an axis running horizontally and parallel to the fork prongs. In order to be able to handle not only the container but also its cover by an unloading vehicle, a further carrier is provided above the rotatably arranged carrier, which is provided with a receiving arrangement for taking hold of the cover of the container, and is vertically adjustable and/or able to be swiveled up and down with respect to the framed.
