Project Overview

In industrial spray painting production, automatic spraying is often used for repetitive coating tasks, while manual spraying provides greater flexibility for areas that require additional attention.
Combining these two methods can be a practical solution for manufacturers handling workpieces with different surface structures and coating requirements.

For Hebei Kaji'er Group in Hebei Province, China, ZHYAO supplied a customized accumulation conveyor spray painting line integrating automatic and manual spraying. The production line connects both operations through an accumulation conveyor system, allowing workpieces to move through the coating process in an organized sequence.

Customer Requirements

The project required a spray painting line that could combine automated application with manual operation rather than relying on a single spraying method.

The main considerations included:

• Integrating automatic spray painting equipment with manual spraying stations.

• Providing suitable coating coverage for different workpiece surfaces.

• Accommodating differences in operating time between automatic and manual stations.

• Maintaining an organized workpiece transfer process.

• Improving production flow while retaining the flexibility of manual spraying.

The key was to coordinate the two spraying methods within one production line. Automatic equipment handles repetitive spraying tasks, while operators provide additional flexibility for areas that require manual attention.

ZHYAO's Engineering Approach

For Hebei Kaji'er Group, ZHYAO adopted an accumulation conveyor system to connect the automatic and manual spraying sections.

The main design considerations included:

• Automatic Spray Painting: Automatic spraying equipment handles suitable, repetitive coating operations, helping maintain consistent application conditions during production.

• Manual Spray Painting: Manual stations allow operators to handle areas that require additional coverage or more flexible spraying.

• Accumulation Conveyor: The conveyor provides temporary workpiece buffering between operations. When one station requires more time than another, accumulation helps accommodate differences in operating cycles and reduces unnecessary interruptions to the production flow.

• Process Coordination: The conveyor arrangement connects the spraying operations and supports orderly workpiece movement through the production line.

Rather than requiring every coating task to be automated, this configuration assigns automatic and manual spraying according to the actual requirements of the workpieces. This provides a practical balance between automated production and manual flexibility.

Project Completion

The completed accumulation conveyor spray painting line provides Hebei Kaji'er Group with a more flexible and coordinated coating production process.

By combining automatic and manual spraying, the line helps improve coating consistency while allowing operators to handle areas that need additional attention.
The accumulation conveyor also helps accommodate differences in workstation cycle times, reducing unnecessary waiting and improving the continuity of production.

This combination of automation and manual operation helps increase production efficiency, reduce reliance on repetitive manual spraying, and provide more stable conditions for ongoing coating operations.
It also gives the customer greater flexibility when arranging different spraying tasks within the same production line.
