Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional feed systems for small parts face challenges such as excessive fall height and vibration-induced damage due to rigid structural connections, leading to increased space and cost requirements for additional conveyance systems.
Innovation Solution
A feed system with two laterally spaced linear vibration conveyor drives decouples the ordering and collecting devices, allowing independent vibration directions and movement speeds, reducing the fall height and eliminating the need for continuous rigid connections, thereby minimizing space and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the collecting device is rigidly connected to the ordering device, then structural stability is improved, but the fall height of parts increases to 120-150mm causing damage risk
Solution Approach 1:
The system is divided into two independently supported structures: the ordering device supported by first linear vibration conveyor drives and the collecting device supported by a second linear vibration conveyor drive. This segmentation allows each component to be stabilized independently while reducing the fall height between them, eliminating the need for rigid connections that caused excessive fall heights.
2Area of stationary object
If the collecting device is vibrationally coupled to the ordering device, then space is saved, but additional conveyors are needed to transport parts back to the start
Solution Approach 1:
The collecting device is equipped with its own linear vibration conveyor drive that can be independently controlled from the ordering device's drives. This dynamic independence allows the collecting device to actively transport parts back towards the ordering device start position, eliminating the need for separate conveyor systems while maintaining spatial efficiency.
3Device complexity
If only one linear vibration conveyor drive is used, then device complexity is reduced, but lateral separation between ordering and collecting devices is insufficient
Solution Approach 1:
The system merges multiple linear vibration conveyor drives (first drives for the ordering device and a second drive for the collecting device) into a coordinated operation. These drives work together with independent controllability, achieving sufficient lateral separation between devices while maintaining overall system functional integration.
4Ease of manufacture
If the ordering device and collecting device share a common vibration drive, then cost is reduced, but independent control of vibration directions and speeds is lost
Solution Approach 1:
Each device is equipped with its own linear vibration conveyor drive that can be independently controlled. The first drives control the ordering device's vibration while the second drive controls the collecting device's vibration, allowing independent adjustment of vibration directions, frequencies, and amplitudes to optimize performance for each specific function.
