Rolling Body Wedge Guide for Bulk Conveyor Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide devices with wedge sliding surfaces for bulk conveyors can cause damage to handled items and irregularities in item flow due to friction and surface interactions, despite efforts to reduce bridging and enhance regular feed.
Innovation Solution
A guide device with a wedge sliding surface defined by a plurality of rolling bodies mounted on parallel shafts, featuring a staggered arrangement and a semi-ogival or ogival profile, which is attached to lateral or central guides using clamps with jaws to minimize contact with item edges and ensure smooth item diversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wedge-shaped guide device with a solid sliding surface is used, then the guide can effectively divert item flow and reduce bridging, but the guide causes damage to handled items and creates irregularities in item flow due to friction and surface interactions
Solution Approach 1:
The patent replaces the traditional solid sliding surface with a system of rolling bodies (rollers or spheres) mounted on shafts. This substitution transforms the mechanical interaction from sliding friction to rolling motion, significantly reducing friction and surface damage to handled items while maintaining the wedge-shaped guide's flow control effectiveness
Solution Approach 2:
The guide device is segmented into multiple independent rolling bodies mounted on parallel shafts, rather than using a single continuous solid surface. This segmentation allows each rolling body to independently contact and guide items, reducing the concentrated friction and damage while maintaining overall flow control
2Object-affected harmful factors
If the sliding surface is made smooth to reduce friction, then item damage is reduced, but the guide's ability to control and direct item flow may be compromised
Solution Approach 1:
The patent replaces the solid sliding surface with rolling bodies that provide a smooth contact surface for items, reducing friction and damage. The rolling mechanism inherently provides flow control through the geometry and arrangement of the rollers, maintaining directional control while minimizing surface interaction
3Reliability
If guide devices are placed upstream from lateral and central guides, then bridging is reduced and feed regularity is improved, but the guide device complexity increases
Solution Approach 1:
The guide device combines multiple functions in a single unit: it acts as a wedge-shaped flow control element, provides a smooth rolling contact surface, and can be configured to work with both lateral and central guides. This multi-functionality reduces the need for separate components, thereby managing complexity while achieving improved feed regularity and bridging prevention
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 reduces damage to items and enhances the regularity of item flow by providing a smooth, staggered sliding surface that minimizes contact with guide edges, thereby reducing friction and surface damage while maintaining effective item diversion and flow control.
Implementation Method 1
The sliding surfaces of the lateral or central guides are formed by a plurality of rolling bodies, which are idly mounted to parallel shafts
Implementation Method 2
The guide device with a wedge sliding surface defined by a plurality of rolling bodies mounted on parallel shafts reduces friction and allows a more regular feed of the item flow
