Bidirectional Welding Carriage Nozzle Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing welding carriages can only operate in one direction, leading to significant unproductive time during the welding of overlapping material webs, especially in large applications like roofs, as they require reversing direction without welding during transport.
Innovation Solution
Designing a welding carriage that can operate in both directions by arranging the welding nozzle in front of the pressing device, allowing for continuous welding by adjusting the nozzle between two positions, and using a hot air blower for efficient heating and pressing of material webs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the welding carriage operates in one direction only, then the pressing device can effectively press the upper web against the lower web during welding, but significant unproductive time is lost during transport between overlapping sections
Solution Approach 1:
The welding carriage is designed with dynamic adaptability to operate in both welding directions (first and second directions) by adjusting the welding nozzle position relative to the pressing device. This allows the system to switch between different operational configurations, enabling productive welding during both forward and return transports, thereby eliminating unproductive transport time while maintaining reliable welding quality through proper nozzle positioning in each direction
Solution Approach 2:
The welding carriage is designed as a multi-functional device that can perform welding operations in both the first and second directions. By equipping the carriage with a welding nozzle that can be positioned in multiple locations (first welding position in front of the pressing device for first direction, second welding position for second direction), the system achieves universal applicability for bidirectional welding, maximizing productivity without compromising welding reliability
2Ease of operation
If the welding carriage is transported in the opposite direction without welding, then it can reach the next overlapping section, but about 40% of working time is lost
Solution Approach 1:
The welding carriage maintains continuous useful action by performing welding operations during both the forward transport (first direction) and the return transport (second direction). The welding nozzle is positioned to enable welding in both directions, ensuring that the carriage is productively engaged throughout the entire transport cycle. This eliminates dead time by converting the previously unproductive return journey into a productive welding operation, achieving continuity of useful action
3Device complexity
If the welding nozzle is fixed in one position, then the device structure is simple, but the welding carriage cannot operate in both directions effectively
Solution Approach 1:
The welding nozzle is designed with dynamic positioning capability, allowing it to be adjusted between a first welding position (arranged in front of the pressing device for first direction welding) and a second welding position (for second direction welding). This dynamic adjustment mechanism provides the necessary adaptability for bidirectional operation while maintaining a relatively simple device structure through straightforward positional changes rather than complex mechanical transformations

AI summary
Welding car (1) operating in two opposing traveling directions (4, 5) comprises a welding nozzle (16) arranged in front of a pressing unit (13) in each traveling direction. An independent claim is also included for a method for welding material strips running parallel to each other in the longitudinal direction. Preferred Features: The welding nozzle can be adjusted between two welding positions (S1, S2) lying on opposite-lying sides of the pressing unit in the traveling directions together with the welding unit. An adjusting mechanism (18) adjusts the welding nozzle along and orthogonal to a first axis running parallel to the traveling directions.
