Mobile Floor Conveyor for Unloading Randomly Stacked Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual unloading of nonuniformly stacked articles from transporting units is labor-intensive and inefficient, leading to bottlenecks at sorting and distribution centers, as irregular stacks often collapse and require manual handling.
Innovation Solution
A floor conveyor system within the transporting unit that collects and conveys toppled articles in a loose arrangement, reducing the need for manual manipulation and enabling efficient unloading by forming a conveying plane close to the floor, which can be moved under the stack to collect articles and convey them further without operator intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual unloading of nonuniformly stacked articles is performed, then articles can be removed from the transporting unit, but labor-intensive handling and bottlenecks occur due to irregular stacking and collapse
Solution Approach 1:
The conveyor unit is made movable rather than fixed, allowing it to be positioned dynamically within the transporting unit to adapt to different stacking configurations and access articles efficiently during unloading operations
Solution Approach 2:
The conveyor unit acts as an intermediary device between the stacked articles and the external conveying system, automatically receiving toppled articles and transporting them out, thereby eliminating the need for manual handling of each article
2Productivity
If articles are manually deposited on a conveyor in a regular manner, then articles can be conveyed out of the transporting unit, but time-consuming manual deposition is required
Solution Approach 1:
The system enables self-service unloading where articles automatically topple onto the conveyor under their own weight or through controlled toppling, and the conveyor automatically transports them out without requiring manual deposition or arrangement by operators
Solution Approach 2:
The conveyor operates continuously to receive and transport articles as they topple, maintaining uninterrupted flow and eliminating the intermittent manual deposition process that previously caused time losses
3Productivity
If a telescopic conveyor is introduced into the transporting unit, then articles can be conveyed out, but articles still need to be manually deposited individually and regularly
Solution Approach 1:
The conveyor unit is extracted from the traditional fixed external position and placed mobile within the transporting unit itself, allowing it to directly access and receive articles from the stack without requiring complex telescopic mechanisms or manual article handling

AI summary
An apparatus for handling articles in a transporting unit, which may be an interchangeable container, having a mobile conveying unit that is moved into the transporting unit to unload the unit, collect and receive articles stacked in the unit under the control of an operator, and convey the articles out of the transporting unit in an unloading direction for further processing. The apparatus generally facilitates removal from the transporting unit with a small amount of effort during the unloading of non-uniformly or randomly stacked articles. The conveying unit has a floor conveyor which conveys in a loose random arrangement the articles that have been toppled or removed from the stack of articles.
