Papertech’s TotalVision™ solutions are often instrumental in achieving required OEE results. Papertech is able to assist companies in calculating the impact a vision solution can have on their OEE and other performance metrics. TotalVision has many applications that address specific problems encountered by tissue producers.

Improve Quality
The DebrisFilterallows you to detect and eliminate defects even in a dusty environment.

Improve Availability
You need clear images. Dirty cameras and lights require maintenance and reduce line availability. Improved lens cleaning solutions and housing designs avoid dirt build-up.

WebInspector cameras and lights display the challenging environment.

WebView pinhole housing design ensures clear images.

Quality Inspection for Embossed & Printed Product

 

Embossed and printed patterns or a combination of both have become a vital component of potential product differentiation among tissue converters. As such the quality of the embossing and/or print has also gained in importance.

Papertech’s QualityVision™ solution provides both offline and online embossing/print quality inspection. With proper converting line control system integration, QualityVision™ can be used to eject poor quality product from the machine, ensuring that it is not packaged and delivered to the consumer.

New quality-based line speed control

Papertech’s Slow-on-Defect converting line speed control system enables line speed control based on the quality of product to be converted. Line downtown due to unexpected quality related process interruptions can be greatly reduced, improving line availability and therefore OEE.

Many converting line operators are used to loading parent reels on their lines without knowing anything about the quality of the tissue they are expected to convert. Unfortunately the quality of the base tissue web has a lot to do with how efficiently the converting line can operate. Large holes, edge tears, folds and creases can all lead to process interruptions when the line speed is too great to allow the defects to pass through the various converting processes without issue.

Fortunately web inspection systems on tissue machines are capable of capturing all web defects contained in a reel. A parent reel quality report defining the location of each defect in the reel can be passed to a converting line when a parent reel is loaded into the unwind cradle. New quality based line speed control systems can interpret the quality report and can control the converting line speed based on predefined criteria. In this manner a line can slow to a crawl to pass a large hole and then speed up again when no web defects are expected. The converting process is not interrupted and line efficiency is not compromised by the usual web break, clean-up and line restart process.
