Transverse Paint Robot Booth Layout for Bumper Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional painting systems for motor vehicle bumpers face issues such as contamination from overspray, inefficient use of space, incomplete painting, and the need for maintenance personnel to enter the paint booth, leading to contamination and maintenance challenges.
Innovation Solution
The painting system aligns components transversely to the transport route, allowing the painting robot to move across the components, reducing booth length, and features a clean room design with separate maintenance and operating levels, enabling efficient painting and maintenance outside the booth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If components are aligned parallel to the transport path for painting, then painting can be performed in the transport direction, but paint particles cause contamination of neighboring painting zones and require larger booth length
Solution Approach 1:
The patent inverts the conventional painting approach by aligning components transversely to the transport path instead of parallel. The painting robot moves perpendicular to the transport direction, painting from side to side as components pass through. This inversion eliminates overspray contamination in the transport direction while maintaining complete painting coverage.
Solution Approach 2:
The patent changes the painting motion from one dimension (parallel to transport path) to another dimension (transverse to transport path). The painting robot traverses perpendicular to component movement, creating a cross-shaped interaction between component transport and painting motion. This dimensional change reduces overspray impact distance and prevents contamination of adjacent zones.
2Object-affected harmful factors
If painting booths are arranged at certain distances or with sufficient air sinking speed to prevent contamination, then contamination between adjacent painting zones is reduced, but the paint booth requires larger amounts of air and increased energy consumption
Solution Approach 1:
Instead of increasing air sinking speed or spacing to prevent overspray contamination, the patent inverts the painting motion to move transverse to transport. This eliminates the need for excessive air flow to contain overspray, as the painting direction is now perpendicular to component transport, naturally containing overspray within the painting zone.
3Productivity
If painting takes place parallel to the transport path, then painting can be performed in the direction of inlet or outlet, but elongated components cannot be painted over their entire length effectively
Solution Approach 1:
The patent employs two-dimensional motion: components move along the transport path while the painting robot simultaneously traverses transverse to the transport path. This cross-motion ensures that the entire surface of elongated components is exposed to the painting application, achieving complete coverage from one side to the other as components pass through the booth.
4Ease of repair
If maintenance personnel enter the paint booth to service application technology, then maintenance can be performed, but dirt is carried into the painting booth causing impairment of painting results
Solution Approach 1:
The patent extracts the maintenance function from the clean painting environment by providing a maintenance flap that opens to the outside. Application technology can be serviced through this flap without personnel entering the painted zone, effectively separating the maintenance access path from the clean painting space and preventing contamination.
5Length of stationary object
If motor vehicle bumpers are rotated after painting to align at right angles to the transport path, then the overall length of the drying station is reduced, but complex rotating stations are required and the painting process is slowed down
Solution Approach 1:
Instead of rotating components after painting to reduce drying station length, the patent inverts the approach by orienting components transversely during painting. This eliminates the need for post-painting rotation, as components are already positioned optimally for the transverse painting motion, simplifying the overall system while maintaining compact dimensions.

AI summary
The invention relates to a paint shop, especially for elongate components, such as e.g. motor vehicle bumpers, motor vehicle sillboards or for components of aircraft and windpower installations. Said paint shop comprises a transport path (4) for transporting components (2) to be painted through the paint shop, a painting robot (13, 16) for painting the components (2) and a travel path (12, 15) for positioning the painting robot (13, 16) along the travel path (12, 15). The invention is characterized in that the travel path (12, 15) of the painting robot (13, 16) extends at a right angle to the transport path (4) for the components (2) to be painted. The invention also relates to a corresponding method of operation.
