Sawn timber unstacking

The sawn timber unstacking unit is used for unstacking and preparing the sawn timber for the press line.
A forklift truck places one or more stacks of sawn timber on the feed-in chain conveyor, which also acts as a buffer. After positioning under the vacuum portal, the timber is unstacked layer by layer and placed on a chain conveyor. Any stacking strips are stripped and collected in a container.
The raw material is conveyed piece by piece through a curvature detection, thickness measurement and moisture measurement system, aligned optimally by a tilting fixture and rejected if the curvature or moisture content is too high.
The boards are separated by an angle transfer unit and pass longitudinally through a metal detector. Optimally prepared, the boards are then transported to a planing machine.

Board optimization

A planing machine equalizes the thickness and width of the boards, which are then scanned on 4 sides by a scanner. With this data, the board goes into the optimization buffer, where the maximum wood yield with the least amount of wood loss is calculated.
In the following cross-cut station, undesirable defects are removed and the board ends are optimized. A later board overlap in the glulam can be precisely predetermined.

Press line

In the layer assembling station, the boards are optimally lined up, glued and stacked. The stacks travel in shuttles to the presses, where they are pressed together under very high pressure (up to 2.5 N/mm²). The high pressure allows material to be saved at the planing machine, so that it is then available for core layer square meters.

Mechanization & logistics

As a competent full-service provider, Fill offers mechanization solutions that are adapted to the individual needs of customers.
With the help of digital products, many processes can be virtually displayed and simulated in advance, and control systems can be developed. The integration of third-party machines, interfaces to high-bay warehouses or control systems is also possible.
Loading

Machines in the network can be fed by forklift truck, manually or fully automatically via a high-bay warehouse and/or an intralogistics solution. The feeding of the bandsaw is adapted in each case to the products to be processed.
This machine is designed with a combined feeder for sawn timber and glulam for core layer production. Any excess capacity of the bandsaw can thus be used for surface layer production.

The separated, inspected boards or glulams are drawn in by the planing machine and planed top and bottom to the set dimensions. Ideally, the board can be conveyed freely again after the planing machine, before being fed to the bandsaw intake.
The SPEEDLINER bandsaw modules can be arranged in blocks of 1 to 6, depending on the requirements. They cut the gluelams into the required number of lamellae with the highest precision. The lamella pack is then planed on the sides (joined) to remove chipping/cuttings and produce a gluable surface.

Separation & unstacking

Fill offers various high-performance mechanization solutions to match the high performance of the bandsaws. The focus here is on extremely gentle handling of the lamellae and maximum system availability.
The cut lamella packages are collected in layers. A vacuum separator deposits the lamellae in layers on a conveyor belt, where they are cleaned in a brush cleaning system. A tandem vacuum stacking system then deposits the lamellae by type. The finished packages are transported to the high-bay warehouse via the intralogistics system.

Joint gluing
TO THE PRODUCT
Gluing of lamellae at the longitudinal edge without longitudinal transport is possible with the SPEED COMPOSER hotmelt systems. The lamellae are simply transported crosswise through the system. Thanks to this basic principle, the machines achieve very high outputs.
Several glue nozzles glue the lamellae simultaneously in the machine – that’s what makes the difference. Whether thick or thin, narrow or wide – there is a solution for every application. Longitudinal and transverse formatting as well as automated loading and unloading are also possible.

Intralogistics

In-house logistics can be implemented in many ways. Shown here is a fully automatic connection to a high-bay warehouse, which allows the complete forklift traffic in the hall to be reduced.
The production of core layers is an important process step in the manufacturing of parquet and 3-layer boards.


The concept
Core layers can be produced using different methods. Depending on the raw material, utilization of up to 75% of the raw material can be achieved with the highly efficient Fill systems. Production systems for core layers are adapted specifically to customer requirements. The HPCC method developed by us has proven to be particularly suitable here.
Process steps:
- Production of gluelam
- Cutting of gluelam/sawn timber into lamellae
- Gluing of lamellae into core layer carpets
Features
- Core layers for all common parquet and 3-layer boards can be produced.
- The production method is adapted specifically to your needs.
The machine is designed according to customer-specific requirements.
We define the resulting technical data in collaboration with the customer.
