Friction Drive Wheel Positioning in Conveying Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveying equipment with a friction drive section requires a large number of components and significant installation space due to the need for a long load bar and large friction drive wheel, which increases costs and complexity, especially when working on a floor at the same height as the guide rails.
Innovation Solution
The load bar is positioned below the guide rails, allowing the friction drive wheel to be covered, reducing the need for a large drive motor and enabling the use of a smaller diameter friction drive wheel, which simplifies the configuration and reduces costs by minimizing the required drive torque and component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the load bar is arranged on the upper side of the guide rails, then the friction drive wheel can be positioned on the working floor, but the installation space becomes significantly large and the drive motor requires large diameter and high torque
Solution Approach 1:
The patent inverts the conventional arrangement by positioning the load bar below the guide rails instead of above them. This inversion allows the friction drive wheel to be arranged below the guide rails rather than on the working floor, significantly reducing the installation space and eliminating the need for large diameter wheels and high torque motors.
2Ease of operation
If the load bar is arranged on the upper side of the guide rails, then the friction drive wheel can be positioned on the working floor, but the number of components increases due to column members
Solution Approach 1:
By inverting the load bar position to below the guide rails, the patent eliminates the need for column members that would otherwise be required to support the load bar from above. This reduces the number of components and simplifies the overall structure.
3Power
If the friction drive wheel has large diameter to provide sufficient drive torque, then the drive motor requires large size, but the installation space becomes significantly large
Solution Approach 1:
The patent resolves this contradiction by inverting the load bar position, which allows the friction drive wheel to be positioned below the guide rails. This enables the use of smaller diameter wheels with reduced torque requirements, thereby reducing the size of the drive motor and the overall installation space.

AI summary
Conveying equipment with utilization of a conveying traveling body includes a conveying traveling body which includes a plurality of trolleys in a traveling direction and a load bar connecting these trolleys and a friction drive section which is provided in the traveling path of the conveying traveling body. The load bar is provided immediately below a pair of left and right guide rails for supporting and guiding the conveying traveling body, and a friction drive wheel which is pressure-contacted with a side surface of the load bar to propel the conveying traveling body in the friction drive section is arranged below the guide rails.
