Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor systems for internal combustion engine exhaust components face challenges in rapid and precise positioning within welding cells, especially when handling heavy components.
Innovation Solution
A conveyor system featuring a conveying vehicle with a chassis and vertically adjustable superstructure, combined with a device carrier and positioning/holding formations, ensures stable and precise positioning through meshing units and locking mechanisms, allowing for heavy loads to be moved and positioned accurately within welding cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional conveying systems are used for heavy components, then the system can handle the weight, but the positioning speed and precision deteriorate
Solution Approach 1:
The conveying system is divided into a mobile conveying vehicle that handles transport and a stationary positioning/holding formation that handles precise positioning. This segmentation allows the mobile unit to move quickly with heavy components while the stationary unit provides precise, stable positioning without being constrained by mobility requirements.
Solution Approach 2:
The positioning/holding formation acts as an intermediary between the mobile conveying vehicle and the welding cell. It receives heavy components from the conveying vehicle and provides a stable, precise interface for welding operations, mediating between the mobile transport function and the stationary welding requirement.
2Manufacturing precision
If conventional conveying systems are used for heavy components, then the system can handle the weight, but the positioning precision deteriorates
Solution Approach 1:
The system separates the transport function (mobile conveying vehicle) from the positioning function (stationary positioning/holding formation). This allows the positioning formation to be optimized for precision without being constrained by the need for mobility, while still handling heavy components through the coordinated action of both segments.
Solution Approach 2:
The positioning/holding formation is prepared in advance at the welding cell location, creating a ready-to-receive stable structure. The conveying vehicle brings components to this pre-positioned formation, ensuring that precise positioning infrastructure is already in place before heavy components arrive, thereby maintaining positioning precision regardless of component weight.
3Speed
If rapid positioning is achieved for heavy components, then the positioning speed improves, but the stability and holding accuracy deteriorate
Solution Approach 1:
The system divides the operation into a rapid mobile transport phase (conveying vehicle) and a stable stationary holding phase (positioning/holding formation). The mobile vehicle provides speed for transport, while the stationary formation provides stability for holding, with each segment optimized for its specific function rather than compromising one for the other.
Solution Approach 2:
The positioning/holding formation serves as a stable intermediary that receives rapidly delivered heavy components from the mobile conveying vehicle and provides a stable, immovable interface for welding. This intermediary absorbs the transition from mobile rapid transport to stationary stable holding, ensuring both speed and stability are achieved at different stages of the process.

AI summary
A conveyor system conveys devices for receiving components to be welded together, especially for internal combustion engine exhaust systems, into and out of a welding cell. The conveyor system includes a conveying vehicle (62) with a chassis (64) that can travel on a subfloor via rollers (68). A superstructure (78) is carried vertically adjustably on the chassis (64). At least one device carrier (14) receives components to be welded together in a position intended for the welding together in relation to one another. A positioning/holding formation (94) is provided on the superstructure (78) and a counter-positioning/holding formation (103) that meshes or can be caused mesh with the positioning/holding formation (94) is provided on the device carrier (14) for presetting a conveying position of the device carrier (14) on the superstructure (78).
