Slitter-Winder Conveyor Tail Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current slitter-winder processes for attaching web tails to customer rolls are inefficient, often requiring manual application of adhesive and heavy, complex devices, which reduces machine capacity and is not adaptable to rolls of varying diameters.
Innovation Solution
Optimizing the conveyor line to position the adhesive applying device within the operating area of the slitter-winder, allowing customer rolls to be rotated between pusher and carrier rolls for precise tail alignment, and using one-sided or double-sided tape with a tail lifting device for efficient tail attachment, while accommodating rolls of different diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate heavy device with support rolls and frame structures is used for attaching web tails, then the tail attachment function is achieved, but the device complexity and machine capacity are negatively affected
Solution Approach 1:
The patent combines the tail attachment function with the existing conveyor line and adhesive applying device of the slitter-winder. The adhesive applying device is integrated into the conveyor system, eliminating the need for separate heavy support rolls and frame structures. The conveyor line itself is utilized to position and support customer rolls during the tail attachment process, merging multiple functions into existing system components.
Solution Approach 2:
The conveyor line is designed to serve multiple functions: transporting customer rolls, positioning rolls for tail attachment, and supporting rolls during the adhesive application process. The adhesive applying device is configured to work with rolls of varying diameters, making it a universal solution that adapts to different product specifications without requiring additional specialized equipment.
2Ease of manufacture
If manual adhesive application is used for tail attachment, then the process is simple to implement, but the productivity and machine capacity are reduced
Solution Approach 1:
The adhesive applying device is pre-positioned along the conveyor line at optimal locations where customer rolls naturally pass during operation. The system is configured in advance to apply adhesive at the correct position on the roll surface, eliminating the need for manual intervention. The conveyor line automatically brings rolls to the adhesive application point, performs the attachment, and continues transport without stopping the production flow.
Solution Approach 2:
The system enables automatic tail attachment where the conveyor line and adhesive applying device work together autonomously. Customer rolls are automatically positioned, adhesive is automatically applied, and the attachment process occurs without manual operation. The system serves itself by utilizing the existing motion and positioning capabilities of the conveyor to perform the tail attachment function continuously during production.
3Productivity
If the adhesive applying device is positioned optimally for critical diameter rolls, then the capacity for critical diameter rolls is maximized, but adaptability to rolls of varying diameters is limited
Solution Approach 1:
The adhesive applying device is designed with adjustable positioning capabilities along the conveyor line, allowing it to adapt to customer rolls of different diameters. The device can be dynamically repositioned to maintain optimal adhesive application geometry regardless of roll size. This dynamic adjustment capability enables the system to process rolls with varying diameters while maintaining high productivity for critical diameter rolls.

AI summary
The present invention relates to an arrangement in a slitter-winder of a fiber web machine, which slitter-winder comprises an unwinder for unwinding a fiber web reel of substantially full-width web, a slitting section for cutting the full width fiber web into partial webs and a winding section for winding the partial webs into customer rolls (10), which arrangement comprises a transport area for moving the customer rolls (10) received from the winding section to the tail attaching area (30), in which an adhesive applying device (35) is located. In the arrangement the distance (L) on the transport area (35) from the push off location of the customer rolls (10) from the winding section to the location on the tail attaching area (31) in which the tails of the customer rolls (10) are attached onto the surface of the customer rolls (10) is defined such that the tails of the web of those customer rolls whose diameter is substantially critical in view of the capacity of the slitter-winder, will be at the area of the operating area of the adhesive applying device (35).
