Kallfass had started the planing unit at Cordes Holz at the turn of the year 2018/2019. At that time, the line was, in essence, explicitly designed for DIY store products all over Europe. “The plant was extremely robust and very quick. In fact, it went so well that, despite our complete satisfaction, we were obliged to order an upgrade of the machine from Kallfass two years later”, explains Andreas Cordes, the owner. His primary wish was to enhance the level of flexibility with regard to dimensioning. And, while they were at it, they could also expand the marking options and, once again, increase the performance of the planing machine.

Takes on everything up to 290 mm and 6 m in length

What emerged was a universal plant that can do everything “from an S10 batten to raw solid structural timber, and from rhombic sections to square planing”, as Cordes describes it. That is considerably more products than could previously be manufactured. The maximum cross section is 290 mm by 165 mm and length of 6 m. Output was increased, despite comprehensive marking, labelling, foil wrapping, bundling and stacking options. The mechanisation is so powerful that the Rex Bigmaster could be enhanced from 100 to 200 m/min. The planing unit was designed for smaller solid structural timber cross sections, but it can now reach twice the speed and handle a much broader dimensional spectrum.

22 fitters for “open-heart surgery”

Kallfass realised the conversion during continuing operation. Up to 22 fitters were required to ensure that the general reconstruction could be achieved within ten weeks with only a single brief shutdown. “Actually, everything was changed, with the plant being expanded in three directions, and a lot of scanners, sensors and marking units were added”, explains Kallfass Project Manager Enrico Goldhahn. “It was open-heart surgery, and we performed it by working in two shifts, including over the weekend. We’re proud that, in spite of all the changes, hardly any stoppage occurred”.

Joint concept

“The plant, as it now exists, was a joint development undertaken by REA Jet, Cordes and us”, says Goldhahn. Among other things, he recommended that a buffer conveyor be installed upstream of the destacking device. The plant picks up an uninterrupted stream of packages for vacuum destacking. “We suggested here that a vacuum destacker with a hoisting unit, stick stripper and ATB stick scanner be selected, and that’s exactly how it was constructed”, relates Goldhahn.
At Cordes, timbers that are too short or unsuitable can be separated upstream of the planing unit. “It’s not unusual for a short piece to be delivered with a package, but I can do without that in the planing mill”, explains Cordes, which is also why a warping meter from ATB in Roggenburg, Germany and a turning device were installed here.

Powerful, despite many processing options and cutting

The first REA Jet labelling run then followed, printing all the required information on the DIY products. The downstream multiple cross-cut saw is from Kallfass. “We can now trim with millimetre accuracy. From 800 mm short timbers to 6 m excess lengths – that means we’re extremely flexible”, says Cordes with delight during the tour of the new planing mill.
He can also call up the plant performance data live on his mobile phone. During the on-site visit of the Holzkurier, a 4m DIY package was completed every 50 seconds.

Six strapping units for small and large pieces

“We delivered the first plant to Cordes with six strapping machines for bundling small and large pieces”, continues Goldhahn. Finally, the packages can also be wrapped in foil. Kallfass also provided an offsetting station for quart packages. The stacking system can handle both small and large packages up to a package height of 2.4 m. “The automatic squared timber stacking is accelerated further, making everything perfect”, says Goldhahn, explaining the success.

Only two operators for the plant

Only two employees work in the plant on each shift. The team monitors the process and ensures that material such as labelling rolls is filled. Just how well the two work together became apparent during the visit. One of them focuses on feeding timber pieces up to the rear of the planing machine. A fault must be remedied here in the case of broken raw timber, or labelling rolls inserted. The second man stands beside the package assembly system. Bearers (squared timbers) or sticks are refilled there.

Praise from the biggest name in Germany

If Andreas Cordes accepts the plant by saying “We’re very satisfied”, his words carry weight. This is the judgement of a man whose corporate group includes German planing specialists such as Osmo Holz in Warendorf, Holz-Henkel in Göttingen and Krages Holzindustrie in Hamburg. In addition, Rettenmeier, a subsidiary, also creates planed workpieces at several locations. This means that the Cordes Group probably has the greatest planing capacity in Germany.

Cordes still has major plans for Bremerhaven. Solid structural timber will be increased to 200,000 m³ per annum, along with an additional 50,000 m³ a year of glued laminated timber. Kallfass is a significant partner for deliveries of these systems. A test run should commence this year.

New Small Diameter Sawmill

The main product, predominantly lamellas for glulam timer, is intended for the supply of glulam plants. Side boards which cannot be processed are supplied to packaging customers. “In future, the sawmill will reduce purchasing considerably for both companies in Wunsiedel and Weißenstadt. However, 100 % self-sufficiency is not possible”, explains Küspert. Wunsiedel primarily proved attractive as a location because GELO Timber had in WUN Bioenergie a pellet producer and cogeneration plant operator as a neighbour. But WUN Bioenergie is not just any neighbour: Küspert is co-initiator of the energy park and, additionally, a shareholder and Managing Director. This creates attractive synergies with, in essence, sawmill waste being exchanged for electricity and heat. Küspert calls the sawmill the “Smart solution 4.0”.

An enormous feat

Construction commenced in Wunsiedel in December 2019. An already tight schedule was adhered to, despite the Corona pandemic, and the first trunk was fed through the saw line a year later in December 2020. “It was an enormous challenge for everyone involved, but we were able to commission the plant within the given time”, says the Managing Director, and he is proud of how successful this cooperation has been. A second shift was already launched a few weeks ago. The sawmill has been designed for an annual output of 350,000 solid cubic metres in two shifts. “That may not seem a lot at first glance, but more than 18 million linear metres of logs need to pass through the plant every year to achieve this output. Our sawmill in Weißenstadt, where we process larger diameters, is only handling 4 million linear metres for an output of 250,000 m³/per annum”, relates Küspert. The Wunsiedel sawmill is intended for thin-end diameters of 8 to 25 cm and a timber length of 2.5 to 5.3 m.

Clean sorting

Main and side boards are conveyed via a tilt destacker onto two separate decks towards the sorting and stacking system from Kallfass in Klosterreichenbach/DE. The mechanisation specialist also installed an automated stick feeder. The main and side boards are fed through an unscrambler onto a curved conveyor. The worker assesses the timbers on the downstream conveyor. If a face section is necessary, he pulls the board up to 0.5 m from the conveyor. During the visit, Kallfass Project Manager Matthias Link pointed out the rollers that make handling of even heavy boards extremely easy.

Single feeding with a TongLoader towards the wane scanner and trimmer occurs in the transverse run-through. The TongLoader grips each piece in a manner similar to a hand, separates the board film, singulating and feeding it into the next conveyor. The significant advantage of the TongLoader is that it can also handle different timber dimensions, piece by piece. Link indicates that the Kallfass sorting system output is up to 120 cycles per minute.

A Microtec scanner determines the dimension and detects the wane. The Variosort sorting control system assigns each board an appropriate box number and information for the downstream Kallfass trimmer. The latter has seven saw blades and can also be used for destructive cuts. “The operator can also indicate additional characteristics for boards through colour marking, indicating conditions such as beetle damage, blue stain or rot”, explains Link.

Boxes up to 30 % larger

GELO Timber decided to pick 40 inclined boxes. In order to reduce stacking on the premises, the Kallfass system can stack packages with a width of up to 1.65 m and a height of 2 m. These dimensions also facilitate best possible exploitation of the Valutec continuous kiln. Kallfass created larger inclined boxes than usual for this reason. “The boxes are around 30 % larger”, says the Kallfass Project Manager.

Full boxes are emptied downwards onto a cross conveyor and separated by a step separator. Kallfass also installed the re-sorting system for kiln packages above the cross conveyor, with one kiln package making up to two or three shipping packages. These are separated in layers through tilt destacking. The stacking sticks fall automatically onto a conveyor belt and are collected separately.

A worker can even assess the quality of both damp and kiln timber again if necessary, or reject undesired pieces. Subsequent to this, the Kallfass mechanisation system creates the layers according to the package specification, and these are conveyed through the Kallfass multiple cross-cut saw. This is equipped with a zero line and four variable saw aggregates. Placement forks then transfer the completed layers to the stacking system. Stacking output is up to twelve layers per minute.

The Kallfass stacking system is equipped with eight double magazines for kiln and dispatch sticks. Kiln sticks are 1.6 m long, while dispatch sticks have a length of 1.2 m. Strip laying is automatic. Finished packages are lowered using a paternoster lift. Damp material is conveyed from there to the Valutec continuous kiln opposite. Shipping packages are conveyed to a Fromm strapping station which Kallfass has retrofitted with an automated feeding system for squared timbers.

As initially mentioned, Kallfass also provided the automated stick feeder for kiln and dispatch sticks. The feeder was automated to cope with the volume of kiln sticks required. Stick bundles are transferred to a cross conveyor and separated. A scanner checks the dimensions and detects damage to sticks such as knotholes and splitting. Unsuitable sticks can be ejected downwards through a flap. Following scanning, the sticks are collected and bundled with ten sticks per bundle. Dispatch sticks are provided using a manually charged belt conveyor. A robot grips the stick packages, filling the stacker magazines with them. The major advantage of this solution is the option to position the magazines variably and still fill them automatically.

Successful project

Complete administration of the sawmill is handled by GELO in Weißenstadt. This enabled them to keep personnel figures low in Wunsiedel. “We currently have 32 personnel working in two shifts. The sawmill can be operated by a mere eleven people during each shift. We wanted to build an absolute jewel – and we’ve succeeded in this in every respect. All the solutions involved were implemented exactly as we imagined. The new sawmill means we are well equipped to face the future”, says Küspert. He is particularly proud of the overall concept involving the neighbouring pellet and cogeneration plant – “It’s a location advantage that nobody can take away from you”.

The complete investment involved EUR 38.5 million. The sawmill location covers an area of 11 ha, 7 of which are presently in use. Küspert also has a few pleasant ideas regarding the rest of the location. “But first, our main focus will be on the new sawmill”, concluded the Managing Director.

Kontinuierlicher Zufluss
mit Leistenroboter EN Continuous inflow with stick robot

Several thousand stacking sticks need to be handled daily at the Sägewerk Egger sawmill in Brilon. “Previously, the continuous filling of stacking plant magazines during main and side board sorting was an enormously laborious task”, relates Jens-Michael von Werder who is responsible for production technology at the sawmill. Up to nine workers were involved in each shift, which meant a considerable number of personnel were working during three-shift operation. For this reason, it was decided to invest in an automated stick handling system with robot charging of magazines at Egger.

Flexible solution

“We found the standard variants available too rigid. We wanted a flexible solution which we could use to handle both drying chamber and stabilisation battens and squared timbers”, continues von Werder. Kallfass, Baiersbronn/DE, offered Egger the perfect solution. “We’d already gain a positive impression of Kallfass during a project in the planing mill. Aside from this, Kallfass has always proved to be a good partner when it came to tackling challenging tasks”, says von Werder. The mechanisation specialist presented those responsible at Egger with a flexible solution that appeared to offer them cutting-edge technology. “We had already installed other automated stick systems in the past, but the project at Egger in Brilon was the most comprehensive to date”, explains Kallfass Managing Director Hans Haist.

Two lines, three robots

The “open-heart surgery”, as von Werder describes it, was performed from April to September, with Kallfass realising the entire automated stick line installation while plant operation continued. The actual installation took two months. “The project went very well and, most importantly, free of accidents. We had practically no downtimes”, confirms von Werder. Egger in Brilon cuts around 1 million m² per annum. The timber is sorted in main and side board plants which are installed in parallel. The new Kallfass line charges both plants with drying chamber and stabilisation battens and squared timbers. Stacking sticks from the dry sorting station are fed together with the squared timbers in uprights to the new Kallfass line. The uprights are discharged onto a buffer conveyor. The system automatically separates the squared timbers from the sticks. The squared timbers are then fed to a stacking system via a separate chain buffer line. The Kallfass control system assigns the squared timbers to both stacking plants based on package data. The sticks take another route, with the Kallfass mechanism separating these and feeding them through a scanner. This determines the dimensions and curvature. Unsuitable sticks are discharged through a flap. The system handles eleven sticks together in each case on an inclined conveyor.

Andrea, Hubertus and Paul

Andrea, the first robot on the line, grabs these eleven stacking sticks and cycles them into the buffer conveyor. “This is designed for around 3000 sticks”, explains Haist. Hubertus and Paul, the two other robots with swivel arms, pick up the stacking sticks if necessary and deposit them in the new Kallfass packet assembly magazines. “The system is designed for an output of 100 sticks per minute”, estimates Haist. “We hold the property rights to this robot charger”, he adds. There is only one stick length for all package widths in the case of stabilisation battens. These are adapted to the package through positioning and shifting of stick placement. “This solution means we are considerably more flexible than with different lengths, but the cost of materials is higher”, says von Werder. Kallfass also upgraded the stacker and delivered the entire control system over the course of this investment. This means that it is now possible to control the placement of more sticks in the lower five to six layers to prevent timber breakage. From Egger’s point of view, operation of the new stick handling system has been both smooth and absolutely satisfactory. “The goal in the area of stick handling is to now manage with four employees per shift. This means the investment will pay off within a very short space of time”, concludes von Werder.

Flexibilität auf eine neue Ebene gehoben EN Flexibility raised to a new level

Hegener-Hachmann Sawmill

The 12 October 2019 saw commissioning of the new sawmill at Hegener-Hachmann. This involved probably the most flexible production processes every realised in a medium-sized sawmill enterprise, posing a planning and technical challenge to all involved.

“Hanxleden 4.0 online sawmill – innovative, resource-efficient sawmill concept for SME” was the project title of the approx. € 11 million investment made by Hegener-Hachmann, Schmallenberg/DE. The new construction took exactly a year from October 2018 to October 2019. After a further twelve months, the planned cutting volume has, in terms of figures, been achieved – but right from the outset.

Exploiting as many resources as possible

Hubertus Hegener-Hachmann heads the company in what is now the fourth generation. He receives significant support in this role from Markus von Weichs who, as his business partner, is primarily responsible for purchasing logs. Having started as a forestry business with an originally small sawmill as a sideline, Hegener-Hachmann had a used head saw and a circular saw when he invested in the first expansion in 2007. “We decided in favour of a completely new construction to ensure the sustainability of our business and, insofar as possible, to be able to cut a broad variety of log types, including in part from our own forestry. Among other things, this enabled us to continue production independently at the location during the production phase. Our goal is to ensure careful and effective use of the resources used during the entire production process”, says Hegener-Hachmann. “We want to process everything at a single location. As a medium-sized enterprise, we can only continue to exist on a broad basis”. What he means by this is not only classic sawn timber such as the raw material for solid structural timber, construction timber or landscaping timber. Hegener-Hachmann is well known in the region for his solid wooden flooring consisting of hard and softwood that goes by the name of “Gutshofdiele”. Larch, Douglas fir and Norway spruce are also processed.

As the entire endeavour is regarded as somewhat of a supra-regional flagship project in terms of flexibility, efficiency and conservation of resources, it received ERDF funding from the Ministry for Environment, Agriculture, Conservation and Consumer Protection of the State of North Rhine-Westphalia as part of the “Ressource NRW” call for projects. This covered 50 % of the components eligible for funding.

What has been created is a modern sawmill with a planned annual cutting capacity of at least 40,000 m³ for soft and hardwood. This has proven highly complex in terms of the processes involved. When it came to the cutting technology, Hegener-Hachmann chose an inclined log bandsaw with a chipper-canter for logs up to 10.5 m in length and with a diameter of 1.3 m. Around 70 % of the timber comes online from the log yard for cutting without presorting. Hegener-Hachmann placed his trust in the know-how of Kallfass (in Baiersbronn, Germany) when it came to mechanisation and the sorting and stacking system. “Aside from the economic viability of the investment, what was decisive for us was the supplier we placed our faith in to accompany us on this journey. The Kallfass solution also impressed us very much, and the company gave us a commitment to realise the project within the estimated time” reasoned Hegener-Hachmann. “Online cutting and the wide variation in product dimensions posed major challenges for us”, remembers Kallfass Managing Director Hans Haist. Kallfass also provided the control unit for the sorting system. “The demanding timbers and varied dimensions meant our programmers were faced with a difficult task“, explains Haist.

A lot of things are possible

The log is in all cases precut on the bandsaw and, following trimming, conveyed on to the Combimes BNK and/or head saw in the Kallfass sorting and stacking plant. However, two other options are also available: “Products with a length exceeding 6 m and a thickness of more than 105 mm, blocks or individual high-quality pieces can be conveyed into special discharge 1 on the head saw or special discharge 2 behind the BNK. These can then be lowered with care to the lower level using a hoisting unit”, explains Hegener-Hachmann.

50 boxes and multiple occupancy

Timbers with a thickness of up to 105 mm, a width of 300 mm and a length of 6 m are fed into the Kallfass sorting system at Hegener-Hachmann. 50 inclined boxes are available here. With inclined boxes, the timber slides down more gently onto the chain conveyor during emptying. This is primarily an advantage where hardwood is involved. “Due to the enormous diversity of our products and the numerous wood types involved, the computer frequently assigns three different types to a single box if necessary”, says Hegener-Hachmann. In this case, the box is emptied when the filling level is reached and the dimensions which are not required are fed once again over a return run and sorted anew.

The timbers to be stacked are separated and assessed again by a worker with regard to quality in the transverse run-through. Inappropriate workpieces can be ejected or shortened here again. The boards are then fed through the Kallfass CNC multiple circular cross-cut saw. This cuts the timbers with zero and four variable saws, depending on requirements. “Cutting is perfect and realised with millimetre accuracy”, confirms the operator. This is followed by layer formation and packet assembly. Haist estimates the output to be up to ten layers or 60 boards a minute during cycling in. The packing system is equipped with eight magazines with automatic stick placement.

Finished packages are lowered using a hoisting unit. Space conditions mean that they are deposited on a roller conveyor located on one side. This pivots the package (which is on rails) through 90°. The package is then strapped and prepared for shipping. Half packages or packages that need to be unpacked without sticks after drying can be picked again using the connected tilt stacker during a renewed passage through the stacking plant.

Both the Hegener-Hachmann sawmill and Kallfass confirm their satisfaction with implementation and commissioning. The focus now is on ensuring together the continuous improvement of in-house processes and the data flow.

Neue Nachsortierung EN New re-sorting system

The Pfeifer sawmill in Uelzen has been in business for almost 30 years and, while timber production was originally around 200,000 cubic metres p.a., the anticipated volume this year is 500,000 m³. This enormous increase over the years means that bottlenecks are experienced at a variety of production stages. One of these was remedied around the turn of the year 2018/19.

The Pfeifer Group sawmill in Uelzen/DE is primarily involved in the production of packaging material and timber. “We’re a completely integrated location, utilising every product created at the site”, stresses site manager Marco De Gennaro in reference to the associated block production and CHP plant. Timber production has more than doubled since the mill was commissioned in 1991. The target volume for 2019 is 500,000 m³. The Pfeifer Group invests constantly to maintain its state-of-the-art technological capability and continuously enhance performance. A further step in this direction was taken in the autumn of 2018 when Kallfass (Baiersbronn/DE), specialists for mechanisation, installed a new sorting system for dry material. A re-sorting plant was already in operation Uelzen, but this had reached the limits of its performance. “We liked the Kallfass concept very much, and the company had proven to be a good partner”, explained De Gennaro. The new system is designed for a volume of 90,000 m³/p.a. “All our dry timber will run through this line in future”, says the site manager. He is particularly satisfied with the millimetre precision with which boards from 600 mm in length are cut, a point he emphasised in our discussion.

Sophisticated solution

The new dry sorting system enables Pfeifer to process raw material from 2.5 to 4 m in length. Karsten Gottschalk, project manager at Pfeifer in Uelzen, quantifies board cross sections at a thickness of 12 to 100 mm and a width of 70 to 250 mm. The generously dimensioned sawn timber discharge is suitable for either double packets with a width of 1.2 m or 2 m wide large packets. A tilt destacker separates the timbers in layers, whereby the stack battens fall automatically onto a conveyor belt. Kallfass installed an additional automatic batten collector for this purpose which, in effect, is a miniature sorting system. “As packets are often stacked in double layers, we separate the boards using a separation stage. In the case of single-layered packets, this can be passed over for a higher output”, explains Kallfass Managing Director Hans Haist during the tour. The boards pass by the operator in a transverse run-through, with the operator assessing them and ejecting substandard examples. This is followed by the tong loader that separates the board film. Kallfass guarantees a performance of 120 cycles per minute. A moisture meter measures the wood moisture. Material that is too moist is separated and dried again. The downstream Kallfass CNC crosscutting saw in Uelzen has four chop saws. This means that cutting with millimetre accuracy is possible as of a capping length of 600 mm. The stacking unit is equipped with magazines for automatic batten positioning. The finished packets are lowered using a hoisting unit where they are strapped and coated in film by an existing plant. The clean packets then stand on a roller conveyor ready for removal. Kallfass project manager Enrico Goldhahn summarises the advantages of the system: “No time is lost during destacking by the buffer, and just as little during packet assembly, thanks to continuous stacking with the auxiliary hoisting unit”. The new Kallfass re-sorting plant currently operates in two shifts. “But we can add another shift if necessary”, says De Gennaro.

Ausgezeichnete Ressourcenschonung und Innovation EN Excellent resource conservation and innovation

With an investment in a new sawmill, Hegener-Hachmann changes its production process and expands its cutting capacity
In the Hochsauerland District, in the east of North Rhine-Westphalia, Germany, a complete new sawmill is under construction. In the future this sawmill will also serve other SMEs as an example of how the use of round timber can be improved and the efficiency of sawmill production can be increased: The Hegener-Hachmann GmbH & Co. KG had submitted its investment project in April 2017 for the “Resource NRW” call for the promotion of small and medium-sized enterprises and received the funding decision in November 2017. The system will go into trial operation in October and will then be open to all interested parties for viewing.

-Excerpt from article-

System configuration

...

Kallfass from Baiersbronn, Germany, supplied the sawmill mechanisation and the sorting and stacking plant. The material to be cut travels at a speed of 60 to 80 cycles/min from the resaw or from the log band saw or the gang saw and can be transported via curve conveyors both to the stacking unit and to the sorting system. The aim is to send over 70% of the production directly to the stacking unit. Eine Mehrfach-Ablängsäge kann Schnittlängen bis zu minimal 600 mm erzeugen, für die Stapelung müssen Längen unter 800 mm allerdings mit einer Doppellänge in der ersten Paketlage abgestapelt werden. Die Stapelmaschine mit automatischer Lattenlegung bildet 8 bis 10 Lagen pro Minute.

...

The sorting system can handle a maximum width of 280 mm and a maximum thickness of 100 mm. The incoming timber is measured in a grid of 500 mm. The sorting system has a capacity of up to 60 cycles/min. There are 50 inclined boxes available, having a volume of 3 m³ each, which can be filled with up to three different widths. Subsequently, a re-sorting unit upstream of the stacking system, from which two widths of the timber are returned for sorting purposes.

...

The minimum cutting lengths of a multiple crosscut saw is 600 mm, however, lengths shorter than 800 mm must be stacked with a double length in the first package length. A stacker with an automatic batten laying function forms 8 to 10 layers per minute.

Lighthouse Project in North Rhine-Westphalia

...

The state government of NRW recognises the company as a nationwide lighthouse project (a model project that aims to have a signal effect for numerous follow-up projects). Visits are possible by arrangement with business partners Hegener-Hachmann and von Weichs. Commissioning of the sawmill is scheduled for mid-October.
