Cargo Conveying Device Height Adjustment for Handler Strain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo conveying systems, such as those described in Japanese Patent Application Laid-Open (JP-A) No. H07-26729, do not effectively reduce the load on cargo handlers during cargo transfer, particularly due to inadequate adjustment of vertical height to match the physique and posture of the handler.
Innovation Solution
A cargo conveying device and system that includes a horizontal direction conveying section, a height adjusting section, and a control section to adjust the vertical height of the transfer section based on sensor data or input information about the cargo handler's physique and posture, ensuring the load is minimized by aligning the transfer height with the handler's waist level and posture, thereby reducing strain on the handler.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the transfer section height is fixed, then the device structure is simple, but the load on the cargo handler increases due to mismatch with handler physique and posture
Solution Approach 1:
The transfer section is equipped with a height adjusting section that enables dynamic vertical movement. The control section operates this height adjusting section to adjust the vertical direction height of the transfer section based on sensor data about the cargo handler's physique and posture, thereby reducing the load on the handler during cargo transfer operations.
Solution Approach 2:
The system changes the vertical position parameter of the transfer section dynamically. By adjusting the height parameter of the transfer section to match the cargo handler's physique and posture parameters detected by sensors, the system optimizes the transfer operation to reduce physical strain on the handler.
2Ease of operation
If the transfer section height is adjusted to match cargo handler physique and posture, then the load on the cargo handler is reduced, but the device complexity increases
Solution Approach 1:
The system uses sensors to automatically detect the cargo handler's physique and posture, and the control section automatically processes this information to determine the optimal transfer section height. This self-service approach eliminates the need for manual height adjustment by the operator, reducing the burden on the handler while the automated control manages the complexity.
Solution Approach 2:
The system implements a feedback loop where sensors continuously monitor the cargo handler's position and posture, and the control section uses this feedback information to adjust the transfer section height in real-time. This feedback mechanism enables adaptive height adjustment that responds to the actual conditions of each transfer operation.

AI summary
A cargo conveying device includes: a horizontal direction conveying section that conveys cargo in a horizontal direction, and that includes a transfer section at which cargo is transferred between the transfer section and a cargo handler; a height adjusting section that adjusts a vertical direction height of the transfer section; and a control section that, at a time at a time at which cargo is transferred between the transfer section and a cargo handler, operates the height adjusting section, and adjusts the vertical direction height of the transfer section.
