Linear Motion Conveyor Drive Assembly Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linear motion conveyors are not readily adjustable to change the direction or speed of product movement or stop the product along the conveying surface, leading to inefficiencies in production line operations and increased noise and vibration.
Innovation Solution
A linear motion conveyor system with a drive assembly that includes a pivotally movable powering unit and eccentric drive plates, allowing for selective movement of the conveyor bed in different directions and speeds, and the ability to stop product movement without de-energizing the system, using a counter-weight and spring legs for support and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the conveyor uses a fixed drive assembly design, then the structure is simple and reliable, but the conveyor cannot be readily adjusted to change direction or speed of product movement
Solution Approach 1:
The drive assembly incorporates a pivotally movable powering unit that can be repositioned along an arcuate path, and eccentric drive plates with adjustable positions, enabling the conveyor to dynamically change direction and speed of product movement without requiring complete system redesign
Solution Approach 2:
The conveyor system allows adjustment of operational parameters including the angular position of the powering unit along the arcuate path and the eccentricity of the drive plates, which directly control the direction and speed of product movement on the conveying surface
2Productivity
If the conveyor operates at high speed to increase productivity, then output increases, but noise and vibration increase
Solution Approach 1:
A counter-weight is provided that can be positioned to balance the moving components of the drive assembly, reducing vibrations and noise generated during high-speed operation while maintaining productivity
Solution Approach 2:
The arcuate path of the powering unit is specifically designed to optimize the motion characteristics, allowing high-speed operation with reduced vibration by distributing forces more evenly throughout the cycle
3Reliability
If the conveyor is stopped to address downstream problems, then product damage is prevented, but production efficiency decreases
Solution Approach 1:
The adjustable drive assembly allows the conveyor to slow down or stop individual sections selectively before problems propagate through the entire system, preventing product damage while minimizing impact on overall production efficiency
Solution Approach 2:
The conveyor system can be controlled in segments, allowing specific sections to be stopped or slowed independently to address downstream issues without halting the entire production line

AI summary
A linear motion conveyor is described and which includes an elongated conveyor bed having a product transporting surface for supporting and transporting a product between the opposite first and second ends thereof, and a drive assembly oriented in force transmitting relation relative to the elongated conveyor bed, and where the elongated conveyor bed, when reciprocated by the drive assembly is operable to move product alternatively between the opposite ends of the product elongated conveyor bed in a first direction; a second direction; and which is further rendered operable to substantially stop the movement of the product located between the opposite ends of the elongated conveyor bed.
