Movable Color Changing Device Control for Coating Robots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coating devices experience significant delays and increased dimensions due to the long distance between the color changing device and the application device, leading to inefficiencies in paint transfer and control signal propagation during color changes.
Innovation Solution
The color changing device control is carried along with the carriage, reducing the distance to the application device and minimizing the number of control lines, allowing for shorter propagation delays and more efficient paint transfer by arranging the changing device close to the application device and its control near the robot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the color changing device is located remotely from the application device, then the device structure is simpler and easier to install, but the paint transfer time increases and throughput decreases
Solution Approach 1:
The color changing device is made movable and is carried along with the carriage that transports the application device. This dynamic configuration allows the color changing device to be positioned close to the application device during operation, reducing paint transfer time while maintaining installation flexibility through the carriage system.
Solution Approach 2:
The color changing device is integrated into the carriage structure, effectively nesting it within the existing mobile framework of the coating system. This allows the color changing device to be transported and positioned along with the application device, minimizing the distance between them and reducing paint transfer time.
2Reliability
If the color changing device control is located remotely, then the control system is simpler, but the switching delay increases due to longer control line length
Solution Approach 1:
The color changing device control is made movable and is carried along with the carriage. This dynamic positioning ensures that the control device remains close to the color changing device throughout operation, minimizing control line length and reducing switching delays while maintaining system flexibility.
Solution Approach 2:
The control device is integrated with the color changing device on the same carriage, merging their positions into a single mobile unit. This consolidation eliminates the need for long control lines and reduces switching delays by ensuring minimal distance between control signals and actuated components.
3Productivity
If the color changing device is carried along with the carriage, then the paint transfer time is reduced and throughput increases, but the device complexity and number of control lines increase
Solution Approach 1:
The guide chain structure is designed to carry multiple functions including both the application device and the color changing device, as well as all necessary control lines and fluid connections. This multi-functional use of the guide chain system consolidates what would otherwise require separate infrastructure, reducing overall system complexity despite the added mobility.

AI summary
A device (10) for coating, in particular painting, objects, especially vehicle bodies, comprises at least one multi-axis robot (18) carrying an application device (14), which in turn is supported by a carriage (20) movable along a guide structure (22). At least one guide chain (44) carries a plurality of electrical and/or optical and/or fluidic lines (60, 66, 74) extending between a stationary connection point (46) and a connection point (48) moved with the carriage (20). A plurality of control lines (50a, 50b, 50c, 50d) extend between a changer device (16) for coating material and a changer device controller (52), which can be selectively supplied with a control signal by the changer device controller (52) to control the changer device (16).The changeover device (16) and the changeover device control (52) are carried with the slide (20).
