Chain-on-Edge Conveyors
Arnold Machine chain-on-edge conveyor systems are designed for precision coating applications requiring controlled part orientation, consistent coverage, and efficient material application. These paint booth conveyor systems support high-volume coating operations involving paint, adhesives, and other liquid coating materials.
Our standardized chain-on-edge conveyors help manufacturers reduce implementation timelines while maintaining the flexibility needed for a wide range of coating applications. Available in single-coat and two-coat configurations, these systems can be adapted for varying part geometries, coating processes, and production targets.
Trusted by automotive, polyurethane, and rubber-to-metal bonding manufacturers.
Benefits of Chain-On-Edge Conveyors
Consistent Coating Coverage
Controlled part rotation and positioning improve coating uniformity across inside diameters, outside diameters, and multi-surface applications.
Reduced Lead Times with Standardized Platforms
Standardized conveyor layouts and core system components simplify implementation while reducing engineering and manufacturing timelines.
Optimized Material Control
Integrated spray controls, flow monitoring, and automation capabilities reduce waste while maintaining stable coating application performance.
Chain-on-Edge Conveyor Options
Single Coat Chain-on-Edge
Single-coat chain-on-edge systems are designed for applications requiring efficient application of a single paint, adhesive, or protective coating. Controlled part rotation and synchronized conveyor movement maintain uniform coverage while reducing manual involvement and stabilizing throughput.
Two-Coat Chain-on-Edge
Two-coat chain-on-edge systems combine primer and topcoat application into a single integrated process. These systems deliver controlled coating thickness, improved adhesion performance, and consistent material application across high-volume production environments.
How Chain-on-Edge Conveyors Work
Arnold Machine Chain-on-Edge cleaning lines streamline the coating process by transporting parts through a series of stations designed for loading, pre-heating, spray application, drying, and cooling. We designed the system to utilize and apply two (2) coating materials throughout the process (solvent or water-based adhesive primer and top coat). The system can also be configured for a single-coat adhesive.
Here’s a detailed look at how they work:
- Load Station: The operator manually loads the appropriate fixtures and parts onto the spindles presented in the load area. This area will have 6' of accessible fixtures for loading and an overhead light for easy visualization. The load station includes an operator work fan.
- Pre-Heat Station: For the primer to adhere to the part, it must be preheated to a predetermined temperature. The pre-heat station in the oven consists of forty-eight (48) spindles to maximize cycle time and oven efficiency. Once the parts have reached temperature in the pre-heat station, they will be conveyed to the primer spray station.
- Primer Spray Station: Parts will enter the spray booth, and the spindle will be engaged with a variable speed belt drive system for part rotation. Two (2) Krautzberger spray guns mounted to FANUC Paint Mate robots are utilized to apply the primer to the part.
The Spray Station controls airflow for maximum transfer efficiency and accommodates ease of cleanup and maintenance.
A Keyence flow sensor will verify that a specific amount of primer has been sprayed from the spray gun between the primer spray station and the primer dry oven. If it does not detect the primer flow, it won’t apply a top coat to the part in the top coat station. The primer pressure pot will be located in the material storage cabinet and provided with all gun connections to the pot.
4. Primer Dry Station: After parts exit the primer spray station, they enter the oven for a series of cycles in the primer dry station. This area will allow the primer to dry further before applying the top coat. There will be eight (8) spindles in this station.
WONDERING WHAT A CHAIN-ON-EDGE SYSTEM COSTS?
Chain-on-edge system pricing depends on your coating process, part geometry, automation requirements, controls, and system configuration. Review the key factors that influence cost before starting your project.
Common Applications
Chain-on-edge conveyors are commonly used to coat straight or profiled cylindrical substrates that require inside or outside diameter coverage.
They efficiently coat multiple faces of a part when needed. Typically, they are used with aluminum or steel substrates ranging in diameter from 1 inch to 5 inches and up to 6 inches tall.
Our CoE conveyors are ideal for large production runs with consistent part sizes and shapes. These systems automate the painting process and reduce the need for manual involvement.
This leads to excellent process control and ensures each part is painted similarly. However, it is important to consider part size limitations and variations when choosing this system.
