Braking Roller Transfer Device for High-Speed Article Direction Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor systems face challenges in efficiently transferring articles at high speeds without damaging articles or conveying members, as existing methods require large transfer devices and complex control systems to prevent collisions and wear.
Innovation Solution
A transfer device with a main conveyor part and a subsidiary conveyor part, where at least one part is a roller conveyor equipped with a braking roller using frictional force to decelerate or stop articles by preventing movement transverse to the conveying direction, allowing for efficient direction change without extensive braking distances or complex control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If articles are conveyed at high speed on conveyor lines, then productivity is improved, but articles or conveying members may collide against the stopper at high speed causing damage and wear
Solution Approach 1:
The patent applies beforehand cushioning by placing a cushioning member between the article and the stopper. This cushioning member absorbs the impact energy when the article collides with the stopper at high speed, preventing damage to both the article and the stopper while maintaining high conveyance speed
2Speed
If a brake is applied to conveyor rollers to stop articles, then articles can be stopped on the transfer device, but a long braking distance is needed when articles are conveyed at high speed
Solution Approach 1:
The patent uses the cushioning member as an intermediary between the article and the stopper. Instead of relying solely on brake force acting directly on the article through the rollers, the cushioning member provides a progressive deceleration mechanism that reduces the required braking distance while maintaining high-speed stopping capability
3Object-affected harmful factors
If conveyor rollers are controlled to limit article speed, then articles can be stopped without excessive impact, but conveyance control becomes complicated
Solution Approach 1:
The patent applies self-service by allowing the cushioning member to automatically perform the speed limitation and impact absorption function. The cushioning member passively decelerates the article through its material properties without requiring active control of the conveyor rollers, thereby reducing conveyance control complexity while still protecting against excessive impact
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
The solution effectively decelerates or stops articles at a short distance, reducing wear and tear, and allows for compact device design without complex control systems, enabling efficient high-speed article transfer.
Implementation Method 1
the brake being designed to prevent the article from proceeding at least to the direction transverse to the conveying direction of the roller conveyor by a braking force acting between the article and the braking roller. The braking force is preferably generated by a frictional force.
