Raute recently highlighted the key features that indicate it’s the perfect time to modernise your veneer peeling line.
Boost yield and profit with cost-efficient peeling line modernisations. This article from Raute has explained how targeted modernisations overcome raw material shortages, increase capacity by 15%, and improve recovery without the downtime of a full line replacement. Veneer, plywood and LVL manufacturers today face problems with raw material variability and shortages on high-quality logs. These problems disrupt production and can amount to significant losses in yield and profit – losses that could be avoided with modernisations of your existing peeling line.
Modernising your peeling line helps you peel more quality and quantity: one can maximise recovery from surface to the smallest core even when the production relies on varying raw material qualities and log diameters.
Typically, modernisations are considered when the peeling line machinery reaches end-of-life stage, and the lifetime of the investment is continued by ‘When Should You Modernise Your Veneer Peeling Line’? upgrading outdated components. Modernisations are also a traditional way to improve the yield, uptime and reliability of an older line.
However, peeling line modernizations are also a cost-efficient way to reach important goals in your production before your technology becomes outdated. By modernizing, you can for example:
Line moderniSations can typically be carried out during routine summer stoppages, significantly faster than complete line renewals. One can start upgrading his peeling line little by little instead of upgrading all machinery at once.
Tailored peeling line modernisations from Raute
Every modernisation project at Raute starts by mapping and documenting the technology and condition of your existing peeling line. It is important to understand how the machinery’s performance has changed since its original installation, to determine the underlying problems modernisation can fix.
During the modernisation process it is important to audit the line’s maintenance needs and complete them before or during the modernisation project to ensure the best possible end-result. Raute technology can be used to modernise both old Raute’s and other manufacturers’ peeling lines. What you should modernise first depends on your production challenges and goals – the following chapters help you evaluate your current situation and options.
Block charger modernisation improves raw material recovery and face veneer production
The most modernised art in a peeling line is typically the block charger, because its upgrade has the biggest impact in improving raw material recovery.
The improvement in recovery depends on the technology you are currently using and the raw material quality available to you. For example, by upgrading an old mechanical block centering solution with a modern Raute block centering analyser, you can increase veneer recovery up to 15% with the same amount of raw material. Accurate block centering also produces up to 20% more face veneer.
Modernising old single-point laser technology in a block charger with modern laser scanning technology can increase recovery 3-5%. Laser scanning determines the optimal peeling position for each block, so you can peel the most sheets with the highest quality. Auto-calibration ensures that block centering is constantly optimised based on the peeling results.
Lathe modernisation improves sheet quality and line safety
With Raute, lathe modernisations are always based on a development plan tailored for your process’ needs. You can modernise your whole lathe or its modules to improve capacity, veneer quality and yield. For example, you can upgrade the carriage feed to improve peeling accuracy and quality, or upgrade the spindles and back-up rolls to improve your yield and reach the smallest possible core diameter.
Another reason for modernising is that a conventional lathe doesn’t adjust pressure optimally in the knife gap against the block, causing vibrations that result in cracks and waviness in the veneer sheets.
When you upgrade your lathe to Raute’s solutions, their optimal peeling geometry provides consistently accurate veneer thickness and strength by keeping the pressure constant throughout peeling: knife angle and nose bar are automatically adjusted as the block gets smaller to prevent cracks and ensure constant quality throughout the veneer ribbon.
Clipper modernisation improves raw material recovery
The more accurate your clipping is, the better you can utilise your raw material. Modernising your clipper with an electric servo motor solution you can improve your clipping accuracy through faster clipping speeds. Servo motors also save energy and are easier to maintain compared to hydraulic solutions.
When you modernise your rotary clipper or renew it completely, you can halve sheet width deviation and improve your raw material recovery. Faster clipping speeds also improve your line capacity.
Modernising the line with analysers improves drying capacity and stack quality
If your mill has a shortage of face quality sheets or over-drying of the sheets causes splits and waviness, you can upgrade your process with Raute visual and moisture analysers for the peeling line.
By modernising the peeling line with a visual analyser, you can increase the amount of full sheets and face quality sheets up to 10%. You can utilise patching and composing simulations to optimise the whole plywood production process. If the capacity in your drying line is not sufficient, you can optimise dryer capacity with improved moisture grading.
If the capacity in your drying line is not sufficient, you can optimise dryer capacity with improved moisture grading. The Raute moisture analyser grades the sheets by moisture class, allowing you to optimise the dryer conditions for each moisture grade and improve end-product quality by avoiding over-drying.
Using the built-in simulators in the peeling line, you can utilise the visual, moisture and strength analysis information to simulate the dryer conditions and optimise the processing of each sheet individually. hen you have the capability to grade sheets better, you can later invest in stacking solutions to further improve your process efficiency.
Improving peeling line safety and performance with a control system upgrade
The safety level of old peeling lines is typically lower than today’s standard. The lines’ control systems can act as a bottleneck for improvements, because old systems cannot utilise the safety features of modern peeling technology.
The modernisation of a control system can therefore enable you to upgrade the safety level of your old peeling line to the required level. Improved data collection in modern control systems also helps you make data-driven decisions on modernising the rest of your production.
Modern control systems allow the utilisation of your process data in a Management Information System like Raute MillSIGHTS. Better data helps you understand what to adjust and improve to reach your important process goals.
