Belt-Actuated Conveyor Guide With Drive Wheel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor systems face challenges in efficiently diverting articles laterally across or off the conveyor belt without noise and high costs, and static side rails can cause friction and damage to conveyed articles.
Innovation Solution
A conveyor belt system with a guide frame that includes wheels, at least one of which is a drive wheel, which engages and drives a pusher to rotate and push articles along the belt surface, using either rollers or a guide belt to divert articles, allowing for adjustable diversion and reduced friction through high-friction materials and adjustable gearing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed-position ejectors, tilt trays, or shoe sorters are used to divert articles laterally, then articles can be diverted across the conveyor belt, but the system becomes noisy and expensive
Solution Approach 1:
The patent replaces traditional mechanical ejectors and shoe sorters with a belt-driven roller system. The rollers are driven by a belt that loops around them, using flexible belt transmission instead of rigid mechanical linkages. This substitution reduces noise by eliminating the impact-based mechanisms of traditional ejectors while maintaining article diversion capability through the rolling action.
Solution Approach 2:
The patent changes the operational parameters of the diversion mechanism by using rollers that rotate in a controlled manner rather than fixed-position ejectors that impact articles. The rollers are positioned at angles relative to the conveyor belt direction, and their rotation is controlled by the belt drive system, allowing smooth, noiseless diversion of articles laterally across the belt.
2Ease of operation
If roller belts with oblique rollers are used to divert articles, then articles can be pushed laterally across the belt, but the conveyor belt becomes more expensive
Solution Approach 1:
The patent segments the diversion function from the main conveyor belt structure. Instead of using a complete roller belt system, it uses a standard conveyor belt combined with separate roller units that are driven by a belt. This segmentation allows the use of cheaper, standard belt materials while adding diversion capability through the roller components, reducing overall system cost.
Solution Approach 2:
The patent introduces an intermediary belt-driven roller mechanism between the conveyor belt and the articles. The rollers act as intermediaries that receive articles from the conveyor belt and push them laterally across. This intermediary mechanism provides diversion functionality without requiring the entire conveyor belt to be equipped with expensive roller structures.
3Ease of operation
If static side rails are used to register articles, then articles can be guided along the conveyor, but friction causes articles to rotate or become damaged
Solution Approach 1:
The patent replaces static side rails with dynamic roller elements that rotate as they contact articles. The rollers are driven by the belt system and rotate in the direction of article movement, creating a rolling contact instead of sliding friction. This dynamic mechanism maintains article registration while preventing the harmful friction that causes rotation and damage to articles.
Solution Approach 2:
The patent substitutes the static friction-based side rail system with a rolling contact system. Instead of articles sliding against stationary rails, they roll over or alongside rotating roller surfaces. This substitution eliminates the harmful frictional forces that cause article damage while maintaining the guiding and registration functions of the side rails.
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 system effectively diverts articles laterally across the conveyor belt with reduced noise and cost, minimizing article damage by using rotating wheels and high-friction materials to support and push articles, while allowing for bidirectional diversion and adjustable operation.
Implementation Method 1
The rotation of the drive wheel actuates the pusher to push conveyed articles along the conveying surface
Implementation Method 2
The guide includes a frame with wheels extending below the bottom of the frame for rotation about axes parallel to the conveying surface of the conveyor belt
Data Source
AI summary
An article guide for a belt conveyor with belt-actuated guide walls. The guide is supported atop the conveyor belt on wheels that ride on the conveyor belt. At least one of the wheels is a drive wheel engaging one or more pushers that push conveyed articles along the belt's conveying surface. The pushers may be rollers rotated by or belts advanced by the drive wheel. The pushers form a moving vertical side wall of the guide.
