Loading Apparatus with Movable Packer Blade for Bulk Material Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for loading bulk materials into standardized transport containers require sequential filling, often using palletized units or skid-steer loaders, which are inefficient and not easily controlled.
Innovation Solution
A device comprising a load bin with a movable packer blade and base assembly, allowing for axial movement to facilitate the transfer of bulk material into a transport container in a single operation by positioning the load bin and packer blade within the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sequential filling using palletized units or skid-steer loaders is used, then the transport container can be filled, but the loading process is inefficient and requires multiple stepwise operations
Solution Approach 1:
The loading apparatus is divided into distinct functional segments: a load bin for receiving bulk material, a packer blade for consolidating material, and a base assembly with drive mechanisms. This segmentation allows each component to perform its specific function efficiently, enabling continuous loading operations without the need for multiple separate loading steps required by conventional methods
Solution Approach 2:
The packer blade is designed to move dynamically within the load bin along the longitudinal axis, transitioning between retracted and extended positions. This dynamic movement allows the packer blade to follow the advancing bulk material, continuously consolidating it as it is discharged into the transport container, thereby maintaining efficient loading throughout the entire process
2Productivity
If a full load of bulk material is transferred in a single operation, then productivity is improved, but control over the loading process becomes more difficult
Solution Approach 1:
The system incorporates feedback mechanisms where the position of the packer blade is continuously adjusted based on the movement of bulk material. The packer blade moves in response to the advancing material front, ensuring that consolidation occurs at the appropriate moment during discharge. This feedback loop maintains control over the loading process even as large volumes of material are transferred in a single operation
Solution Approach 2:
The packer blade automatically adjusts its position based on the flow and accumulation of bulk material within the load bin. As material is discharged, the packer blade is pushed forward by the material pressure and gravity, requiring minimal external control input. This self-adjusting behavior simplifies operation while maintaining effective consolidation throughout the single-operation loading process
3Manufacturing precision
If the packer blade is positioned to consolidate bulk material, then loading density is improved, but the passage of material from the load bin may be obstructed
Solution Approach 1:
The packer blade is designed with dynamic positioning capability, moving along the longitudinal axis of the load bin in response to material flow conditions. When bulk material needs to pass freely, the blade retracts; when consolidation is needed, the blade extends. This dynamic adjustment ensures optimal loading density without creating persistent obstructions that would impede material discharge
Solution Approach 2:
The packer blade acts as an intermediary element between the bulk material and the transport container. Rather than being a fixed barrier, it serves as a movable consolidation tool that processes material as it flows. The blade's intermediate position allows it to consolidate material effectively while still permitting continuous passage from the load bin to the container

AI summary
An apparatus (10) for loading a transport container with a load of bulk material has a load bin (20) positioned for axial movement atop a base assembly (40). A packer blade (90) is positioned inside the load bin for movement relative to the load bin in the same axial direction. The load bin has an open first end (22) and a second end (24), with a pair of vertical side walls (66) and a substantially open top surface. Drivers (60, 92) are provided for the axial movements. Material is loaded into the load bin, the openable end of the transport container is placed around the first end of the load bin, and the load bin is extended into the transport container until the packer blade is inside the transport container. By retracting the load bin while retaining the packer blade inside the container, the load is transferred.
