Highest paper quality and production efficiency thanks to state-of-the-art web inspection at Chinese paper manufacturer

isravision signet neuAt the manufacturing plant for Guangzhou Paper CO., LTD., production managers decided to install an ISRA VISION web inspection system with the capability to identify and classify relevant quality defects with the highest degree of reliability. The goal is to ensure that the highest quality demands are met at the fastest possible production speeds. Only an integrated automated inspection system can satisfy this requirements profile - and the only one that absolutely stands out with the technology required is offered by ISRA VISION.

The Chinese Guangzhou Paper CO., LTD., specializes in the manufacturing and global export of a variety of different paper products.

In order to continuously guarantee its customers the high quality they demand while ensuring the highest possible efficiency, the company made the decision to install a web inspection system on the paper machine PM1 line in Guangzhou. This machine, with a web width of 4,800 mm, produces newspaper and fine paper products that weigh between 45 g/m² and 70 g/m² at a web speed of 1,600 m/min.

Guangzhou Paper CO., LTD. made the investment in a PAPER MASTER inspection system from ISRA VISION. It uses five cameras that support the maximum resolution and ensure the highest processing speeds. The inspection of surfaces in transmission is conducted with high-power LED illumination. Not only does the surface inspection system identify all of the relevant quality defects 100% of the time, but it also categorizes them as well.

The crystal clear images of the recorded defects allow the PAPER MASTER inspection system to expertly categorize defects, providing the basis for a highly accurate quality inspection and defect documentation. With this in hand, the paper manufacturer knows exactly what kind of quality is being produced. The classifier teaching makes use of a similarity filter, making online inspection 1,000 times faster than that offered by any other system.

The manufacturer Guangzhou Paper CO., LTD., placing great importance on using state-of-the-art manufacturing equipment, chose ISRA VISION based on their position as the market leader in machine vision and as the only supplier to offer more than 30 years of experience in surface inspection and in producing web break monitoring systems. In addition, ISRA VISION systems are based on the most recent state-of-the-art technologies. The high-end inspection components are tried and tested, meeting the latest compliance requirements. The high availability of the inspection systems help reduce maintenance costs and require less spare parts.

The PAPER MASTER web inspection system will now play a major role in ensuring that Guangzhou Paper CO., LTD. only produces the highest quality products at an above-average production efficiency. The resulting optimized processes supplied by the inspection system will significantly improve efficiency for the plant.

PAPER MASTER: Easy set-up, highly flexible, fast ROI

New generation of fastest high-resolution line-scan cameras to be presented at China International Paper Technology Exhibition 2014

2014-08-14 090950 isra vis logoISRA VISION, the world’s leading supplier of surface inspection systems for the pulp, paper and tissue industry, presents new groundbreaking inspection technology at China International Paper Technology Exhibition 2014. PAPER MASTER Web Inspection System (WIS) guarantees a new precision in detecting and classifying defects. The new generation of fast high-resolution line-scan cameras paired with high-end illumination does not miss out on any defect and is your eyes along the entire production line. Innovative classification software identifies what kind of problem you are dealing with. The result is an unprecedented precision to secure highest possible quality standards.
 
This quality step ahead in the automated inspection of all paper and tissue surfaces is made possible by ISRA’s further development of classic web inspection. PAPER MASTER WIS is a ready-to-use solution with the latest, fast, high-resolution cameras, combined with brightest illumination technology. Standard resolutions up to 8000 pixels in CD/camera and 640 MPixels/second true processing speeds deliver highest detection performance for any application. Easily and fast integrated into the production line, PAPER MASTER WIS offers an eight times better resolution than conventional cameras and is able to find all defects even down to microns.

The sophisticated components provide the basis for an ultra-fast and highly precise web inspection. Data processing is performed in real-time, enabling a most reliable high-speed classification. Altogether, the operator receives fully automated results that had not been possible with previously available technology.

Crystal clear images of defects by PAPER MASTER WIS give the basis for accurate defect classification. Even smallest irregularities can be detected and evaluated. Modern classification software identifies and classifies defects in no time. Previously, it took a long time to set up classification systems and teach defects. Today, installation goes fast and easy thanks to ISRA’s defect catalogue that provides basic information to start classification in only a few hours. Quickly accessible, detailed defect information helps to adjust parameters and take actions before it becomes a real problem for production. Further, quality is measured permanently, and producers are now able to make sure that only flawless material is delivered to their customers.

Conclusion: PAPER MASTER WIS is the key to significant improvements to quality. It guarantees high-performance web inspection and enables 100% quality control and decrease in customer claims permanently. With a quick installation, high-performance web inspection and outstanding quality measurement, WIS promises a fast return on investment and highest quality standards with a decrease of quality defects up to 70%.

From Tissue World magazine, ISRA VISION PARSYTEC will present its newest IntelliCam at Tissue World 2013, a Web Break Monitoring and Web Inspection System technology that leads to higher quality and increased output of tissue production.

The concept ensures best available image quality under every environmental condition, based on compact stainless steel ruggedised housing; hosting camera, illumination and processing units all in one. For a clear view, the IntelliCam cleans the housing glass with a brush or blade at programmed frequency. This provides permanent optimum visibility into process and web, and therefore best monitoring requirements are given at any time.

The integrated embedded processor provides complete image analysis and long video sequence buffering. Strong LED flash lights are used in order to illuminate even hard-to-see paper machine areas.

It is equipped with state-of-the-art cameras providing fast acquisition rates and the highest sensitivity and resolution currently available.

Ines Hermann, marketing manager, said: "With the new standard of camera, tissue producers are able to operate their machines at higher speed due to continuous quality monitoring."

ISRA VISION PARSYTEC has over 500 installations worldwide and offers turn-key solutions for all kind of pulp, paper and tissue processes: automatic web inspection for defect recognition, web break monitoring for process efficiency control and software tools for surface quality yield management. Unified Web Break Monitoring and Web Inspection provides tight process and quality control leading into higher process and total production efficiency.

For tissue producers, an extended product portfolio covers the full range of surface inspection tasks along the process chain - from wet end to converting.

Yankee Protection avoids sheet breaks in the tissue machine and fire in the hood. Defect Handling entails a slowing of the converter for specific defects to prevent sheet breaks at converting.

Yield management software modules complete the inspection by final quality grading of tissue rolls.
