Variable Chain Conveyor for Continuous Painting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chain conveyor systems in painting processes face inefficiencies due to the need for large facilities to accommodate stopping and starting mechanisms, leading to space constraints and increased defects from partial painting during power failures or pauses.
Innovation Solution
A conveyor apparatus with variable conveyors that allow a section of the chain conveyor to remain in position or accelerate independently, enabling continuous operation without stopping or accelerating the main driver, using a rail system with moving and fixed rails to adjust conveyor length and speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the chain conveyor stops or pauses to perform additional work on certain articles, then the additional work can be performed, but the whole process is delayed and defects occur in other processes
Solution Approach 1:
The conveyor system is divided into multiple independent variable conveyor sections (first variable conveyor, second variable conveyor, etc.) that can operate independently. This allows one section to pause for additional work while other sections continue moving articles through the process, preventing system-wide delays and maintaining overall productivity.
Solution Approach 2:
The variable conveyors can dynamically adjust their operating state between moving and remaining in position based on process requirements. This dynamic control enables flexible pausing at specific locations without stopping the entire conveyor system, allowing additional work to be performed on certain articles while maintaining continuous flow elsewhere.
2Adaptability or versatility
If additional driving apparatus or pallet systems with stopper devices are added to pause the conveyor for additional work, then the additional work can be performed, but the facility size increases
Solution Approach 1:
The variable conveyor sections serve multiple functions: they can move articles through the process, pause at specific locations for additional work, and resume movement. This multi-functionality eliminates the need for separate stopper devices or additional driving apparatus, maintaining facility size while providing the required adaptability.
Solution Approach 2:
The pausing capability is merged into the existing conveyor structure through variable conveyor sections that can control their own movement. This integration combines the functions of transport and positioning within a single system, avoiding the need for separate stopping mechanisms and reducing overall facility requirements.
3Ease of operation
If the chain conveyor moves at identical speed throughout the process, then the system is simple to operate, but painting precision is insufficient and space requirements increase
Solution Approach 1:
The variable conveyor sections can dynamically adjust their speed and positioning to optimize painting precision. By controlling the movement speed and pausing at precise locations, the system achieves accurate painting without requiring the entire conveyor to move at identical speeds, maintaining operational simplicity while improving precision.
Solution Approach 2:
Different sections of the conveyor have different operational characteristics optimized for their specific functions. The variable conveyor sections can pause or move at different speeds according to local process requirements (such as painting zones), while other sections maintain continuous movement, achieving precision where needed without compromising overall system simplicity.
4Ease of operation
If the painting apparatus moves along the chain conveyor at identical speed, then the system is simple, but the painting process cannot be accurately performed and space requirements increase
Solution Approach 1:
Instead of moving the painting apparatus along with the conveyor at identical speed, the variable conveyor sections pause in position while the painting apparatus operates. This inversion of the movement relationship allows the painting apparatus to work on stationary articles with high precision, eliminating the need for complex synchronized movement while improving painting accuracy.
Solution Approach 2:
The variable conveyor sections pause in position before the painting operation, positioning the articles in the optimal location for painting. This preliminary positioning action ensures that articles are stationary and properly positioned before the painting apparatus begins work, achieving high painting accuracy without requiring the painting apparatus to move along the conveyor.

AI summary
A conveyor apparatus is provided. The conveyor apparatus includes a rail formed in a closed curve line, a chain conveyor that moves along the rail, a driver that drives the chain conveyor, and a first and a second variable conveyors that relatively vary lengths of at least two portions of the chain conveyor so that a section of the chain conveyor remains in position while other portions of the chain conveyor moving along the rail.
