Laser-Sensing Transport Vehicle for Cargo Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned guided vehicles struggle to accurately adjust cargo loading positions when mobile shelves or trucks deviate from predetermined positions, leading to potential cargo handling issues due to deviations in cargo handling positions.
Innovation Solution
A transport vehicle equipped with a cargo loading unit, a point group acquisition unit using a laser to acquire a point group, and a distance specifying unit to determine distances in both left-right and front-rear directions between cargo and adjacent objects, allowing for real-time correction of cargo loading positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cargo handling position is determined on the assumption that the mobile shelf or truck will deviate, then the system can handle deviations, but the cargo cannot be loaded with the space therebetween closed
Solution Approach 1:
The laser scanner acquires point groups of the mobile shelf or truck before cargo loading begins, allowing the system to detect and calculate position deviations in advance. This preliminary detection enables the unmanned guided vehicle to adjust its cargo handling position proactively, ensuring both deviation handling capability and precise cargo loading with closed spaces.
2Productivity
If the unmanned guided vehicle arrives at the predetermined cargo handling position, then cargo handling can proceed, but it is difficult to recognize how much the mobile shelf or truck has deviated
Solution Approach 1:
The laser scanner continuously acquires point groups of the mobile shelf or truck, and the control unit calculates the actual position based on these point groups. This feedback mechanism provides real-time deviation information to the unmanned guided vehicle, enabling precise adjustment of the cargo handling position while maintaining high cargo handling efficiency.
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
Enables accurate adjustment of cargo loading positions even when mobile shelves or trucks deviate, ensuring proper cargo handling and preventing overlap or gaps between cargo units.
Implementation Method 1
a point group acquisition unit that is arranged at a position to be capable of irradiating cargo loaded on the cargo loading unit and a cargo loading position with a laser, and acquires a point group by horizontally irradiating the laser

AI summary
A transport vehicle is provided, which is capable of adjusting a cargo loading position afterward even if a mobile shelf, a truck, or the like deviates from a predetermined position. The transport vehicle 1 includes: forks 16; a point group acquisition unit 22 that acquires a point group PG by horizontally irradiating a laser; and a distance specifying unit that specifies a distance in a left-right direction between the cargo loaded on the forks 16 and an object adjacent to a cargo loading position based on the acquired point group PG. The point group acquisition unit 22 is arranged at a position to be capable of irradiating the cargo loaded on the forks 16 and the cargo loading position with a laser.
