WEINIG scanner systems: Recording everything at a glance

Fully-automatic, high-performance lines are being used increasingly in modern wood processing, even in rough mill applications. An upstream scanner is an integral component of the overall system. The scanner records the relevant timber data on all sides in the blink of an eye (knots etc.) and supplies this to the machines downstream, such as rip and cross-cut saws, at full production speed. Without automatic recognition systems like this, the cutting performance of the overall systems would be unimaginable. This places the highest demands on the control technology.

The WEINIG development departments provide solutions for highly automated production lines. We guarantee reliable production processes - for hardwood and softwood applications. WEINIG offers the right configuration for every application.

The CombiScan Evo series sets new benchmarks in the further development of scanner technology. The innovative, completely revised product portfolio offers higher performance and significant optimization of the traditional scanner strengths. The CombiScan Evo series provides solutions across all process stages: from ripping and cross-cutting applications to a range of variants for use as a sorting scanner.

The EasyScan series offers efficient performance features at attractive prices and is specially designed for the requirements of smaller companies with simple cross-cutting applications. It is capable of feeding a single cross-cut saw and has the efficient and powerful optimization of the CombiScan Evo series.

With EScan, the product range has been extended to strength grading. A range of different options for sorting by strength now enable certified production of glulam, DUO, TRIO and other strength-related products.

Doing the job properly

The straight path to success: Tony Sulimro (Owner of San Lim) and his Head of Production Nguyen Dinh Khanh. To the left and right: Tran Hoia Son and Chung Van Dang (Michael Weinig Asia)

Vietnam is among the “Tiger countries” of South-East Asia. San Lim Furniture is one example of the impressive growth in the region. The company's factory halls contain more WEINIG technology than the Expo Center in Tauberbischofsheim. 

With GDP growth of more than six percent in 2016, Vietnam was among the fastest-growing nations in the world. The furniture industry is a significant contributor to the boom. San Lim Furniture is one of the companies in the sector that has particularly succeeded in exporting high-quality products to North America. During their rapid expansion in recent years, they have also invested in production technology. In doing so, they have set out a clear path: Only the best and only a complete solution from a single source. Their search for a partner who could fulfill these requirements led San Lim almost inevitably to the WEINIG Group. Owner Tony Sulimro underlines: “The brand name and the pioneering technology were instrumental in our decision.” Outstanding service was another key factor according to the customer. In our Singapore subsidiary, WEINIG has a point of contact in the region with an excellent track record. In 2015, San Lim purchased 14 machines and systems covering almost the entire value chain in wood processing. The spectrum ranges from an automatic moulder and tool grinding machine to an optimizing cross-cut saw and CNC center as well as automation and scanner technology. “With this production line, San Lim is a technological trailblazer in the region,” says Anthony Teo of Michael Weinig Asia. The company’s experiences with the highly-efficient technology have been positive from the outset. So much so that San Lim ordered another 16 machines in 2016. “Such confirmation of customer satisfaction may be almost unique worldwide,” beams Anthony Teo. 

Maximum performance at minimum temperatures

Satisfied management: Production Director Alain Mignault and Quality Manager Daniel Tremblay, delighted with their wood recovery, with Thierry Labetoulle from Luxscan (center)

In Chibougamau, in the far north-east of Canada, the winters are long and icy. Forestry and mining have shaped life in the region since time immemorial. However, high tech has also naturally embedded itself. 

Chantiers de Chibougamau, a subsidiary of timber construction group Nordic Structures, predominantly manufactures solid wood beams, CLT structural elements and glulam. The efficient production operation also includes the use of scanner technology. Until recently, a Luxscan C180 was operating without a hitch in 2 to 3-shift operation in the harsh environment. Based upon their positive experience with the machine, the company has turned to WEINIG once again. This time, they have opted for an EasyScan. In its latest iteration, the EasyScan+ offers detection performance on a par with WEINIG’s high-end scanners. The EasyScan+ is also equipped with a scatter laser, which enables optimal crack detection and significantly increase timber yield.

The scanner is working at Chantiers de Chibougamau in two-shift operation. The wood is checked by the camera-based system according to defined quality criteria before being sorted and fed to the two Weinig Dimter cross-cut saws. The production line operates at a speed of 225 m/min and achieves a throughfeed output of 32,000 m per shift. Thanks to the excellent detection performance, the system achieves a wood recovery of 84 percent. This represents a 20 percent increase in value creation compared with the previous model and significantly reduced losses during subsequent finger jointing. The Chantiers de Chibougamau team is completely satisfied with the new investment. A delighted Quality Manager Daniel Tremblay says: “It’s like a dream. We never have to worry about the scanner. You simply have to press start and stop and the result is a consistent product to a very high standard of quality.”

“It worked almost at the push of a button”

The detection performance of scanners is constantly improving. Installation of these high-tech devices is now almost a matter of “plug and play”. The example of Möbelwerke A. Decker demonstrates how it all works. 

At Decker, wood arrives as raw boards and leaves the factory as a modern piece of furniture. Managing Director Andreas Decker: “We are the only furniture manufacturer to offer such high value creation: We produce furniture entirely out of solid wood and even manufacture the solid wood panels used ourselves.” The company is constantly investing in new machinery to remain at the cutting edge of technology. “Based upon our many years of successful collaboration, we opted for systems from the WEINIG Group,” explains Head of Production Rainer Weitzenbürger. In summer 2016, the customer commissioned a CombiScan Evo C200 and a ProfiPress T “Next Generation”. The CombiScan detects unwanted wood features and forwards the data to the OptiCut 450 Quantum high-performance cross-cutting system. The OptiCore Direct visualization displays the scanner results including the required crosscuts. The scanner has four-sided laser and color cameras. “Due to the high resolution, the scanner detects color defects such as sapwood or redheart extremely reliably. In the latest version, we have improved width measurement, which is particularly beneficial for panel production,” says Jörn Dittgen of Luxscan. The scanner is equipped with laser sensors as well as lasers to detect diagonal cracks (Angle-Cracks Module – ACM). Thanks to the use of four specially positioned lasers, the ACM is able to obtain decisive additional information for detecting diagonal cracks. Commissioning was simple: “The scanner worked almost at the push of a button,” says Weitzenbürger. (Source: Holzkurier) 

Spot landing

Glulam production at the push of a button: The bosses at Stabilame have found an intelligent solution.

From bent, warped beams to straight, visually appealing glulam products is a difficult journey. Rapid throughfeed is less important than the right result. Stabilame in Belgium has discovered perfect quality with an entry-level scanner. 

Rustic, aesthetic visuals are required for the lamellae produced by Stabilame for glulam products and block house walls. Smaller wood defects are tolerated but the work piece must be straight. With diameters of up to 60 cm and large lengths, this is not quite so easy. Mechanical "extrusion" is not an option. However, Stabilame has achieved perfect results with an astute, inexpensive solution. What is surprising is that the solution is based upon scanner technology that is usually at home in rapid processing. Furthermore, in the WEINIG ShapeScan and EasyScan models, even compact entry-level technology has proven completely adequate for the demanding application. In the ShapeScan, a sensor initially measures the curvature and/or warping of the products sorted by strength. The calculated data is fed into the subsequent optimization on the EasyScan. The WEINIG OptiCut 450 Quantum then processes the cutting list in accordance with the pre-defined quality. Stabilame are impressed. Particularly since the system, including charging, can even work unmanned during throughfeed. All that remains is to de-stack the pallet of raw timber in advance.

The force of the forest

50,000 Swedish forest owners trust in Södra. The corporate group markets the wood of its members across the entire value chain. A perfectly organized operation that only invests in the best production technology. 

Long-term growth is the number one objective at Södra. The existing manufacturing technology is, therefore, constantly reviewed and must meet the highest standards with regards to quality and future viability. Even for the sawmill, where scanner technology has long been used, the company keeps a close eye on market developments. Project manager Roger Johansson was familiar with WEINIG's CombiScan+ top model from a previous role with another company. The scanner was used at the company to their complete satisfaction. That was the catalyst for the replacement investment. Flexibility was a key point in Södra's target specification document. Which is not surprising. After all, Södra currently processes 17 different profiles/widths, previously involving quite a complex adjustment process. With the optimized profile software of the new CombiScan+ S 600, however, new profiles can be set up and produced in no time. Södra particularly appreciates the improved performance and higher yield through optimized value creation Simple operation and intuitive handling are the icing on the cake. Luxscan Sales Director Jean-Philippe Hildebrand appreciates the endorsement: "Our scanners offer the customer genuine added value and are perfectly adaptable to individual requirements. Södra recognized this and took full advantage."

Operation future

Minimal malfunctions and easy to use: CombiScan+ at JCE Chile

J. Christer Ericsson, founder of JCE Group, which takes his name, is a legend. A creative mind who could always spot future opportunities. When the former naval officer launched a second career as an entrepreneur, he initially remained faithful to his previous field. He enjoyed instant success with his idea of replacing the chains for loading ship containers with plastic belts. Another idea, namely building spectacular hotel platforms in open sea, earned him global renown. Today, JCE Group is an international investment company based in Gothenburg. The head office manages an enormous breadth of activities, which are characterized by progressiveness and sustainability. The group has maintained its links with the sea via offshore commitments in wind power projects. Another cornerstone is the wood industry. The group is a market leader in the chipboard plant and sawmill sector. In partners, they seek companies that can help them shape their innovative focus. WEINIG meets these requirements. JCE Chile S.A. acquired a CombiScan+ C 600 scanner for 4-sided detection with laser and color cameras, which is also equipped with X-ray sensors. The system is used for the production of finger-jointed goods and panels. Given that previous practices included marking with chalk, the technology heralds a new era in optimization for JCE Chile. The previous output of up to 22,000 running m/shift has been increased to 30,000. The company also invested in an OptiCut 450 FJ+ high-speed optimizing cross-cut saw. This achieves a timber yield of up to 6 per cent while the defect rate has decreased dramatically compared with the old cross-cut system. "Previously, cutting was a huge problem. Not now," report JCE.

No regrets about using outsiders - the Dauerholz story

Terrace

Peter Weller says: "If I want an entire concept, there is no alternative to Weinig."


The idea started in Hamburg. The production was outsourced to MeckPom. Using outsiders has really given the company a boost. But the Dauerholz decking boards are an obvious hot topic.

A few years ago, a Hamburg carpenter made a sensational discovery: Unlike similar preservatives, hot wax seeps into the core of the wood ensuring genuine deep protection. The researcher found bold investors who believed in the idea, primarily because the outdoor area, with decking and construction timber, provides vast scope for ecological wax-impregnated wood with its high resistance to weathering, moisture and pest infestations. A production plant was built in the perfect spot in Dabel near Schwerin.

The customized Dauerholz production line was designed and installed in close cooperation with the project specialists at Weinig Concept. As well as a planing and profiling machine, a high-speed optimizing cross-cut saw, a curve cross-cut saw, a scanner and a finger-jointing line, the site also includes a tool grinder machine from the Weinig portfolio. “We wanted to keep the entire process in-house as well as being completely autonomous in terms of tool preparation,” says Peter Weller, explaining the decision.

Dauerholz placed greatest emphasis on optimization of wood recovery and finishing. We performed a recovery analysis and established that we had more than halved cutting losses, reports Peter Weller. This success is also partly attributable to the new moulder. The moulder is equipped with “floating” vertical spindles whose flexible bearings allow it to follow the natural curvature of the wood over long lengths. This prevents “snipes” and “dips” on either end of the work piece and eliminates finish planing with further chip removal.
