Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing splicer devices for producing corrugated cardboard webs often result in lateral offsets between joined material webs, leading to increased production costs due to necessary further processing.
Innovation Solution
A splicer device with a tiltable deflection roller and information processing unit that adjusts the material web's running direction based on positional information from sensors, ensuring precise alignment and minimizing edge trimming through a storage carriage that can displace and tilt to guide the material web effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional splicer devices are used to join material webs, then the splicing function is achieved, but lateral offsets occur between joined webs requiring further processing
Solution Approach 1:
The storage carriage is made displaceable along a displacement path between first and second end positions, allowing dynamic adjustment of the material web guidance. This dynamic positioning enables precise alignment compensation without requiring complex fixed adjustment mechanisms, thereby improving alignment precision while maintaining ease of manufacture
Solution Approach 2:
Sensor assemblies detect the position of material webs and provide feedback to the control unit, which automatically adjusts the storage carriage position and deflection roller tilt to compensate for lateral offsets. This closed-loop feedback system achieves high alignment precision without increasing production costs through manual intervention
2Productivity
If the storage carriage is made displaceable to form material web loops, then the splicing process is improved, but the device complexity increases
Solution Approach 1:
The storage carriage serves multiple functions: it forms material web loops, guides the material web, and provides lateral positioning adjustment. By combining these functions into a single displaceable component, the device achieves improved splicing efficiency without proportionally increasing overall structural complexity
Solution Approach 2:
The deflection roller acts as an intermediary element between the storage carriage and the material web, translating the carriage's displacement and tilt movements into precise guidance adjustments. This intermediary mechanism simplifies the overall structure while maintaining high splicing efficiency
3Manufacturing precision
If the deflection roller is made tiltable to influence running direction, then alignment precision is improved, but the device complexity increases
Solution Approach 1:
The tilting mechanism of the deflection roller is controlled by an actuator driven by the control unit based on sensor feedback, replacing complex manual mechanical adjustment systems. This automated control achieves high alignment precision while reducing overall mechanical complexity through electronic control

AI summary
The invention relates to a splicer device comprising a first unwinding device to unwind a non-endless first material web and a second unwinding device to unwind a non-endless second material web as well as a joining device for joining together the non-endless material webs to form an endless material web. The splicer device further has a storage carriage, which comprises at least one deflection roller to deflect the endless material web and is displaceable between two end positions to form or loosen material web loops of the endless material web. The at least one deflection roller has a respective central longitudinal axis and is tiltable between two tilt end positions to influence a running direction of the endless material web. The splicer device further has an information processing unit to cause tilting of the at least one deflection roller depending on positional information regarding the endless material web and/or another endless material web to be joined thereto.
