Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor systems face challenges in achieving proper product positioning, particularly for food products, which require alignment and orientation for efficient packaging, often necessitating manual repositioning and additional machinery, leading to increased costs and wear.
Innovation Solution
A conveyor system comprising a vibratory product distribution conveyor, a flighted lateral transfer conveyor, and a product loading conveyor with continuous belts, which aligns products through a series of tiers and transfer belts, and a recycling system to handle misaligned products, minimizing manual intervention and machinery requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If guides and pushers are used to position product on conveyor, then product alignment is improved, but device complexity and manual dressing requirements increase
Solution Approach 1:
The vibratory conveyor system uses self-aligning features where the vibration and pan geometry cause products to automatically orient themselves in the desired position without external guides or pushers. The product's own weight and the vibratory motion create natural alignment, eliminating the need for complex positioning mechanisms.
Solution Approach 2:
The system employs vibratory motion of the conveyor pan to facilitate product alignment. The vibration causes products to shift and settle into properly oriented positions based on the pan's inclination and oscillation direction, achieving alignment through dynamic mechanical action rather than static guides.
2Manufacturing precision
If manual dressing is used to reposition rogue products, then product positioning accuracy is improved, but productivity and time efficiency deteriorate
Solution Approach 1:
The vibratory conveyor system automatically corrects misaligned products through its self-aligning features, eliminating the need for manual intervention. The continuous vibratory motion and strategic pan geometry ensure that even rogue products self-correct, maintaining high productivity without sacrificing positioning accuracy.
3Manufacturing precision
If additional machinery is added for product repositioning, then product alignment capability is improved, but maintenance costs and wear increase
Solution Approach 1:
The system achieves product alignment through the inherent properties of the vibratory conveyor itself, without requiring separate repositioning machines. This single integrated approach reduces the number of moving parts and potential failure points, lowering maintenance requirements and wear.
Solution Approach 2:
The alignment function is merged into the primary conveyor operation rather than being a separate process. The same vibratory mechanism that transports products also aligns them, eliminating the need for additional dedicated alignment machinery and reducing overall system complexity.
4Manufacturing precision
If extensive product handling is used to achieve alignment, then positioning accuracy is improved, but product damage risk increases
Solution Approach 1:
The system uses gentle vibratory motion rather than forceful mechanical handling to achieve alignment. The vibration allows products to gradually shift into proper positions through controlled oscillation, minimizing impact forces and reducing the risk of damage to fragile items.
Solution Approach 2:
Products align themselves through the vibratory environment without being manually manipulated or forced into position. This self-aligning process eliminates the need for aggressive handling mechanisms that could damage sensitive products.
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 aligns and positions products with minimal manual repositioning, reducing wear and maintenance costs while ensuring sanitary processing and quality control, particularly for fragile food items.
Implementation Method 1
The shaker base is oscillated at relatively high frequency (e.g., at 5-100 Hz), and at low amplitude. As the vibration is transmitted to the product transport pan, product essentially 'bounces' across the pan in accordance with any inclination of the pan, and/or in accordance with the direction of oscillation imparted to the pan.

AI summary
A conveyor system includes a product distribution conveyor which spreads products across its width and aligns them in uniform orientations while doing so; a lateral transfer conveyor which receives a row of the aligned products from the product distribution conveyor, and rejects unaligned and/or excess products while doing so; and a product loading conveyor which receives each row of products and loads them into packaging in a neatly aligned array.
