Ensuring dust limits at the workplace

New sampling system determines the inhalable dust content and the respirable dust fraction that may reach the alveoli.

Ensuring dust limits at the workplace

The new stationary tester VC25 JI equipped with a sampling head for particulate matter.

The new stationary tester VC25 JI developed by Jung Instruments measures particulate matter and the total dust content at workplaces. A new sensor, manufactured exclusively for Jung Instruments, takes precision of flow rate measurement to the next level. The instrument complies with all commonly applied standards as it uses proven, IFA-licensed sampling heads.

Dust pollution legislation requires that in order to comply with dust limits at workplaces the dust content measurement has to be carried out with appropriate precision right next to the workers or directly at the emission source.

Jung Instruments“ new VC 25 JI dust collection system is a stationary sampling unit designed for the measurement of the dust load at workplaces, such as workplaces for welders, or of the kind found at mixing and filling plants in a wide range of industries.

The system measures the inhalable dust content (specified in IFA standard 7284) and the respirable fraction that may reach the alveoli (specified in IFA standard 6068) according to EN 481, using sampling heads for dust and particulate matter licensed by the German IFA Institute for Work Safety.

Central elements of the new instrument are the robust high-precision flow rate meter, manufactured exclusively for Jung Instruments, and the new, extremely user-friendly electronics. The electronic system is designed to always keep the flow rate at exactly 22.5 m3/h, independent of any ambient temperature or flow resistance variations. The instrument comes with a software for self-diagnosis to monitor the filter condition. Fault messages, e.g. about an obstructed or defective filter, are indicated on the LCD.

Thus the instrument combines new technology for controlling the flow rate and for facilitating handling with tried and tested methods for dust measurement.

According to Erwin Jung, founder and managing director of Jung Instruments, his customers benefit not only from the new technology of the instrument: „Many companies use dust sampling systems that have already reached their economic end of life, but not so the measuring heads that work with the samplers. The new VC 25 JI is the solution many operators have been waiting for: They can now continue using the existing measuring heads.“

The cartridges accommodating the flat filters are easy to handle and can be conveniently taken or shipped to a laboratory for subsequent gravimetric and chemical analyses.

Pixargus: Inspecting inspection systems

Optical surface inspection of profiles for the rubber industry: On-site calibration saves time and ensures reliable production along the entire process chain.

Pixargus: Inspecting inspection systems

The calibration unit has been designed for on-site use

Pixargus, leading manufacturer of inspection systems for profiles and tubings, is now offering on-site calibration services for Pixargus systems by means of a newly developed mobile calibration unit. The advantage for the customer is that the inspection system does not have to be removed from the production line and shipped to Pixargus but will be immediately ready for use after the calibration has been done.

More and more end customers insist on the implementation of automatic optical surface inspection in the production processes. Therefore, high precision and long-term reliability of the inspection systems have become increasingly important aspects for tubing and profile manufacturers, since these systems have meanwhile become an integral element of quality control in many works. This makes regular checks and calibration of these systems indispensible.

With the Pixargus inspection badge and the MSA certification, profile manufacturers can attest to their customers that the inline quality control systems in place work flawlessly and reliably.

The mobile calibration unit contains a certified calibration specimen with several boreholes, the distances and diameters of which have been precisely measured. As the surface inspection is based on line scan cameras, the specimen must be constantly in motion while being measured. Pixargus solved this requirement by means of a motorized traversing unit which constantly moves the specimen back and forth. Inspection systems may be equipped with up to eight cameras. In order to allow each individual camera to be tested, the specimen can be rotated while being clamped in the calibration unit.

During each test, the system captures 600 measurements per camera. Pixargus evaluates the data and makes them available to the operator. After completion of the evaluation process, the system will receive the new parameters, which can also be fed to the system via remote access from the Pixargus head office. The calibration guarantees the customer that surface defects of the profiles, if any, are detected at the correct positions and that their sizes are correctly measured.

Michael Frohn, Service Manager at Pixargus, has already successfully accomplished numerous onsite calibrations: „Pixargus is the first company in our industry to offer a mobile calibration service. It is no longer necessary to remove the systems from the production lines. The calibration is a matter of just a few hours and does not require any major preparations. Our customers particularly appreciate that they can call on us, for example, in case of a plant downtime scheduled at short notice.“

Dirk Broichhausen, Vice President Sales & Marketing at Pixargus, sees the mobile calibration service as part of the overall performance of the Pixargus inspection systems: „The quality requirements to be coped with along the entire process chain are becoming ever more exacting. Fewer and fewer operators are responsible for more and more plants and have to safeguard the plants“ process capability and the repeatability and stability of the processes. For us this means that it is no longer sufficient to react quickly and competently but that we must also be able to act preemptively. By „competently“ I understand that we do not have a run-of-the-mill call center but a hotline operated by a team of technicians and engineers who have direct access to the product management system and are capable of providing qualified answers to our customers“ questions – in real time.“

Heinrich Georg Maschinenfabrik: Leveller for plates of „excess width“

Lasers measure the flatness of plates of max. 3.200 mm width in the hundredth of a millimeter range.

Heinrich Georg Maschinenfabrik:  Leveller for plates of "excess width"

The new plate levelling machine, on the right one can see a cassette change car.

In May GEORG delivered on schedule a levelling center for large-sized aluminium plates to a customer in Russia who is primarily a supplier for the aircraft industry. This machine has been designed for plates of up to 3.200 mm width and max. 12 m length. The heart of the line is the GEORG high-duty plate leveller RM 120 x 3200. Supported by precise measurement technology, GEORG achieves an ultimate flatness of plates during the levelling process, finally documenting a flatness accuracy in the hundredth millimeter range.

After having performed the workshop preliminary acceptance in Kreuztal where GEORG had perfectly fulfilled all specifications instantly, the line is now on the way to the customer. With this new line the customer will be able to produce „laser-competent“ material of extremely low stress which will not distort in the laser welding process of different components.

Initially, GEORG has designed the levelling center for the levelling of large-size aluminium plates but steel plates can be processed as well. In order to meet the very high demands of aircraft manufacturers regarding the flatness of plates between 1 and 10 mm thickness, GEORG has provided the leveller with two levelling roll cassettes including rolls of different diameters. So the customer may use the suitable set of rolls for each plate thickness. With the automatic cassette change car the cassettes can be exchanged in less than 15 minutes.

The machine is equipped with eleven rows of back-up rolls for the precise levelling of plates with edge waves – frequently occurring with annealed aluminium plates – over their entire width. In the infeed area, the levelling rolls have a larger distance in order to facilitate the infeeding of wavy plates. Furthermore the infeed roller table is equipped with centering units to allow different angular positions of plates.

At the leveller exit a laser measuring beam for flatness measurement with eleven stationary triangulation lasers has been installed. The results provide the operator at the control desk a perfect overview during the running process. Thus, he can decide immediately and safely whether the levelling result fulfills the tight flatness requirements or whether another leveling process has to be performed. For the fast transport of plates back to the infeed roller table the machine is equipped with a reversing drive and a fast lifting function of the upper levelling roll set.

For checking and documentation of parameters such as flatness, thickness, length, width and diagonal of the finished plates the line is provided with a stone-type measuring table of highest precision, installed next to the runout roller table. This measuring table enables a one-hundred percent check of plates. For this measurement a measuring beam with triangulation sensors and cameras moves above the plate and detects the geometrical data with an accuracy of a hundredth of a millimeter.

Pixargus: With image processing technology for sealing profiles to goal-line technology in football world cup

From a start-up company to a leading systems provider: Image processing for the quality control of carbon fiber fabrics used in lightweight automotive construction

Pixargus: With image processing technology for sealing profiles to goal-line technology in football world cup

Core elements of the carbon fabric inspection system: eight high-resolution GigE CCD line scan camer

At Vision 2014, Pixargus will present its latest development in image processing technology: integrated measurement solutions for inline quality control of carbon fiber fabrics used to make car body components for a new generation of electric vehicles made by a leading German premium car producer.

In the production of carbon fiber fabrics, the new WebControl Carbon Fiber Systems, developed by Pixargus and arranged downstream of the weaving units and the automatic tying machines, check the quality of the fabric from powder coating down to the reeling process. The systems operate with sensors that measure and inspect the product as it is being powder-coated and sintered. They check the product for missing bundles and provide information for the analysis of material defects. All measurements – with the exception of the weight per area measurement – and all the inspections are based on optical systems.

As a general contractor, Pixargus supplies several measuring systems, interlinks them in a network and combines the data measured by the various sensors into a global data map, allowing the customer to analyze the results within a context, not isolated from one another. The systems decide autonomously whether a product should be shipped or not … and, as a last consequence, they will even decide on the stoppage of production.

Dr.-Ing. Jürgen Philipps, one of the founders and managing directors of Pixargus: „One of the challenges in image processing today is to compile the results from different inspection systems and sensors in an easy-to-comprehend form on the screens or in quality reports. Therefore, also image processing software must be designed to be able to handle distributed computer systems. And what is more, the systems are used in the industry. Therefore, the performance of the systems no longer exclusively depends on the underlying algorithms, but also on their robustness in field use. They must be able to cope not only with natural process variations, but also with the typical operating conditions prevailing in industrial plants – 24 hours a day for 360 days a year.“

From a start-up company to a general contractor for total quality control systems

In only 15 years, Pixargus has evolved from a three-man start-up company into a leading technology provider, whose image processing systems have become indispensable assets at the world“s leading manufacturers of high-tech components.

Already during their assignments at the Institute of Plastics Processing (Institut für Kunststoffverarbeitung IKV) of the Technical University RWTH of Aachen/Germany, Rene Beaujean, Björn Lindner and Jürgen Philipps had concentrated on the development of systems for the surface inspection and measurement of plastic profiles. In 1999, they established Pixargus as a spin-off of the Institute.

Since then, the company has evolved in a way characteristic of successful, medium-sized companies specialized in image processing technology: from single unit to series production, from single sensors to integrated quality assurance solutions, from the evaluation of isolated measured data to automated „ship-or-block“ decisions …. and eventually „start-and-stop“ decisions for the production machines.

With its very first product, ProfilControl, Pixargus soon became the leading provider of optical surface inspection systems for rubber profiles in the automotive industry. Worldwide almost all major manufacturers of rubber profiles for the automotive industry use Pixargus systems to control the surface quality and the dimensional accuracy of their products.

Shortly afterwards, Pixargus introduced its ProfilControl Dimension (PCDX) systems for profile measurements, immediately followed by the Dual Head solution, which combines the measurement and the surface inspection of profiles in one unit. As a next step, in order to assure the quality of extruded rubber profiles as early as possible in the production chain, Pixargus took product control „upstream“ by introducing ProfilControlRoughness (PCR) 20/40, a system capable of checking the quality of the compounds in an automated procedure.

Over time, the service and product portfolio has been further diversified. In addition to the market leadership Pixargus gained with its ProfilControl systems, the company has become increasingly renowned as specialists in providing solutions for highly complex inspection tasks. Jürgen Philipps: „Pixargus“ specialty is that we can provide complete, integrated solutions even for most challenging out-of-the-ordinary requirements. In other words: Pixargus starts where others stop. We started to acquire our extensive image processing know-how long before we founded Pixargus. Therefore, our technological lead is backed by two decades of active research and development.“

Based on its initial products, the company developed systems for cables, for tubing – first for the automotive industry, later also for medical applications – and for pipes, as well as for windshield wipers, profiles for window frames and precision profiles made of metal.

Another development milestone was the transition from circular, 360-degree measurements of profiles to the inspection of sophisticated, highly textured web material, such as woven and non-woven fabrics, foils and plates. The image processing algorithms developed by Pixargus are capable of detecting defects concealed in highly textured structures.

2014: Image processing technology conquers the football field

The same technology as used by Pixargus for the measurement of defects in moving profiles forms the basis of the goal-line technology for football fields developed by the Pixargus subsidiary GoalControl. Based on images sent by up to 14 cameras installed around the pitch, this image processing system instantly detects whether the ball has passed over the goal line and sends a message to a watch worn by the referee. The system enjoyed a successful premiere at the 2014 FIFA World CupTM in Brazil. GoalControl performed excellently during all 64 games. In many critical situations, the system helped the match officials make the correct decision, especially for Bryan Ruiz“ goal for Costa Rica against Italy and in the match between France against Honduras, when the referee decided on a goal after having received the confirmation from the goal-line system.

Worldwide almost all major manufacturers of automotive rubber and TPE profiles use Pixargus systems for surface inspection and profile measurements. Also in medical engineering Pixargus has set new standards with its inline surface inspection systems for medical tubing.

In the production chain for CFRP, Pixargus systems detect weaving and material defects, inspect the gap width, measure and check whether the powder has been properly deposited, measure the degree of sintering, and so on. To allow a comprehensive data analysis, the data measured by the various sensors are interlinked and integrated into a “global data map”. This makes it possible to optimize production processes and guarantees 100 percent flawless products.

Intelligent quality and process control in CFRP manufacturing

Systems solution for inline inspection of carbon fiber fabrics

Intelligent quality and process control in CFRP manufacturing

Optical inspection of the degree of sintering in carbon fiber fabric production

At Composite Europe, Pixargus – reputed as a supplier of individual measuring systems – will present itself as a provider of systems for integrated measurement solutions for inline quality control of carbon fiberfabrics, a product increasingly used in applications such as automotive and aviation construction, and wind power plants.

Starting out from optical measurement and inspection devices for rubber and plastic profiles, Pixargus has continuously expanded its range of products. The Aachen/Germany-based company now also offers integrated inline quality control systems for CFRP production processes. By applying these systems, Pixargus customers ensure that all products leaving their works are 100 percent defect-free.

With the exception of the weight per area, all measurements and inspections are based on optical methods. A key element of the technology is the Pixargus WebControl CarbonFiber system, which inspects the web surface. With the framework software architecture, which has been specifically developed for the inspection of this type of surfaces, it is possible to map the complex web structure while detecting defects typical of carbon fiber material.

As a general contractor for total quality control systems, Pixargus supplies several interlinked measuring systems and combines the data measured by the various sensors into a global data map, allowing the customer to analyze the results within a context, not isolated from one another.

This systems approach is characterized by a wide array of applied technologies, namely surface inspection of the heavily textured fabrics by means of complex image processing and pattern recognition algorithms, optical measurement with an accuracy down to the micrometer, lighting solutions using innovative LED technology and non-contact thickness measurement.

An example of these systems solutions is the inline inspection of the carbon fiber fabrics used to make car body components for a new generation of electric vehicles made by a leading German premium car producer. The system comprises hybrid quality assurance systems for measurements and inspections during processes as diverse as the application of powder, the detection of missing bundles, the analysis of material flaws and sintering.

Dirk Broichhausen, Vice President Sales & Marketing at Pixargus, explains which factors were decisive for winning this contract: „Our company was chosen as contract partners for all quality assurance assets used in the final inspection of the products for various reasons. One reason was our technological lead in the field of optical surface inspection. Another important reason was the good experience the car maker – to whom our customer supplies his products – had previously made with other Pixargus measuring systems. And the experience which we have gained during previous projects with important players in the automotive industry was certainly another decisive factor.“

In their systems, the Pixargus specialists combine many years of experience in sensor technology – mainly in optical measuring systems – with expertise in industrial production processes and innovative materials. According to Björn Lindner, one of the founders and managing directors of Pixargus, his company“s growth strategy has turned out successfully. „This system solution underpins that Pixargus has evolved from a manufacturer of individual sensor systems to a systems provider of comprehensive inline quality assurance solutions for complete production lines. This also becomes obvious in the fact that we combine separate measuring systems into networked solutions and the data from different sources into a global picture.“

Pixargus: New module for optical inline inspection assures flocking quality

Surface inspection system specialized in typical flocking defects

Pixargus: New module for optical inline inspection assures flocking quality

ProfilControl Surface systems inspect the surfaces of profiles made of plastics or rubber.

At „K 2013“, Pixargus will be presenting its new Flock Detection module, which inspects sealing profiles during the flocking process. The system ensures that, in the case of irregularities in the flocking, corrective action can be immediately taken. This guarantees that only prime material is shipped to the customers.

The new module belongs to the family of Pixargus ProfilControl Surface (PCS) systems, which inspect the surface condition of profiles in an inline process. It detects and classifies in real time typical flocking defects, such as missing or clumping flocking material, or longitudinal grooves. The PCS systems are typically installed at the end of the flocking line.

Pixargus developed the module for the optical inline inspection of door and window seals as used in the automotive industry. These sealing profiles have to comply with extremely exacting quality demands.

The flocking material must be applied highly uniformly in order for the profiles to reliably fulfill their sealing function. As in the vehicles the seals are partly visible, imperfect appearance of the surface may be reason for rejects.

The direct feedback of ProfilControl data into the process makes it possible to correct the flocking process without delay, ensuring that the poor flocking result does not continue along the profile.

As soon as a system detects a defect, it triggers a graphic display of the defect and a signal, which may be used to mark out-of-spec sections of the profiles or control automatic cutting or sorting equipment. Thus ProfilControl relieves the human inspector from the monotonous task of visual checks and painstaking sorting of the profiles into good or bad.

Within the measuring range, the profile surface is uniformly illuminated by an LED light ring and scanned by six high-resolution line-scan cameras arranged at angles of 60° around the profile. With these six line-scan cameras of more than 2,500 pixels each, the system detects surface defects down to 50 m.

The Flock Detection module takes advantage of all features of the ProfilControl systems, including the Automatic Head Positioning (AHP) function. Whenever the product changes, the AHP system automatically readjusts the cameras into optimal positions for the new profile. This ensures that the system always captures the complete surface, even if the profile contours are complex.

By introducing AHP, Pixargus has made operation of the system even more user-friendly, while eliminating possible sources of error. The operator is relieved from his task of having to readjust the cameras whenever the profile shape changes. At the same time, AHP guarantees reproducibility of the system settings.

Pixargus: Automatic defect density evaluation takes yield management out of the grey area

Inline inspection of profiles made of plastics or rubber: New surface inspection module has a handle on complex user requirements specifications

Pixargus: Automatic defect density evaluation takes yield management out of the grey area

ProfilControl Surface systems inspect the surfaces of profiles made of plastics or rubber.

At „K 2013“, Pixargus will be presenting its new „Defect Density Management“ solution for the surface inspection of profiles made of plastics or rubber. With this system, it is possible to combine the evaluation of surface defect types and count over a defined length of the product. Profile manufactures will be able to fulfill even highly complex requirements specifications set up by their customers, while minimizing the out-of-spec rate.

The new Defect Density Management (DDM) module makes it a lot easier for profile manufacturers to produce exactly to customer specifications. They will from now on also ship products which in the past would have been graded as „out-of-spec“ because of a subjective evaluation based on vague criteria.

The module belongs to the family of Pixargus ProfilControl Surface (PCS) systems, which inspect the surface condition of profiles in an inline procedure.

Optical inline inspection systems have reached a high standard in detecting and classifying surface defects on profiles. However, the contextual evaluation of defects, which includes logical operations between defect criteria, has so far remained in the grey area.

In numerous specifications, especially those set up by automotive producers, the „ship or block“ decision depends on OR-operations. A customer may reject a profile, for example, if over a specified length of the product there is one severe defect or one medium defect plus several small defects.

Human inspectors would be unable to cope with such logical operations while doing visual inline inspections of the product. They would be able to base their decisions but on subjective impressions. The Defect Density Management solution, however, weights every single surface defect and sums up the obtained values over a certain length of the product. The inspection system sends out a signal as soon as the value exceeds a defined threshold. The signal can be used to mark out-of-spec sections of the profiles or control downstream cutting and sorting equipment. This relieves the human inspector from the monotonous task of visual checks and painstaking sorting of the profiles into good or bad.

The direct feedback of ProfilControl 6 data into the process makes it possible to correct the production process without delay, ensuring that defects do not continue along the profile.
