Continuous material supply
Whether in layers or destacked, transverse or longitudinal, a continuous supply of timber is vital when feeding machining processes such as planing or sawing. Accelerating rollers ensure high feed speeds. The use of a slow-down belt is necessary as of a speed of 150m/min to decelerate the pieces after planing.
Fully automatic material flow
Stacking of timber (including in multiple lengths) can be realised with placement forks or vacuum lifters, with the timber being collected in layers and deposited layer by layer on the shipping package to be formed. Dispatch strips can be laid between several layers to stabilise the shipping package. Strip laying is automatic. Where necessary, the shipping package is stabilised additionally through final strapping. Squared timbers can be optionally included on the package underside, and the packages can be pressed hydraulically together if desired. Customers who do not wish to have stabilising strips (e.g. because the package only needs to be transported within the company) may avail of offset stacking.
Effective air circulation, thanks to dry sticks
Wooden sticks are laid between each layer when stacking timber that is still damp in kiln packages. The intermediate sticks ensure adequate air circulation during drying and accelerate the drying process. The drying sticks are laid by stick magazines.
Option: Workpieces of different widths can also be stacked with spacing with the aid of a servo slide.
Greater stability during handling
Bundling involves the joining of individual timbers to form a compact bundle. Bundles are easier to handle and have a greater degree of stability. This is a major advantage when, for example, stacking or during transportation. Between 8 and 11 bundles can be automatically strapped every minute, depending on the bundle dimension. A labelling option is available, either on individual boards or on the complete timber bundle.
Flexible and efficient
The ends of raw or planed timber workpieces are cut with millimetre accuracy to the desired fixed lengths in cross-cut saws. The workpieces can be processed individually or layer by layer. Powerful saw motors and feed speeds of max. 50 m/min ensure a high throughput.
Several cutting programs can be stored to ensure maximum production flexibility, or data can even be imported from ERP systems and master computers.
Separation of single and multiple packages
High performance and a high cycle rate
For separating single and multiple packages with and without intermediate sticks upstream of planing and sorting systems. The packages are received in a transverse direction by a lifting unit, pivoted through approx. 45° and conveyed on to the skid edge. Layer by layer, the timber pieces now slid over a skid edge (which can be flexibly adjusted) to even out distortions in the layer.
Minimising setup times
Tilt destacking of double packages can halve setup times, minimising production costs as a result. The intermediate strips in double packages can be removed with the aid of a stick stripper (optional) and collected and sorted for further use or disposal.
Careful and gentle at a medium cycle rate
Vacuum suckers lift the topmost layer of a package and deposit it gently in a transverse direction on the conveyor. This careful handling is particularly suitable for avoiding surface damage to planed workpieces. The vacuum destacker is suitable for production lines with short to medium cycle rates.
Longitudinally and transversely at a low cycle rate
This destacking involves pushing the uppermost layer of a package to the downstream process. Pushing can occur in a transverse or longitudinal direction, depending on the space requirement. This destacker is used on production lines with a low cycle rate.
