Accurate stacking helps minimize waste in veneer production

Veneer stackers

From simple one stack solutions to comprehensive stacking stations, Raute technology helps you stack evenly so you can automate sheet processing and minimize waste.

Even veneer stacks are a sign of efficient sheet handling

In peeling, drying, composing and patching lines, veneer sheets are categorized into stacks to be delivered to the next processing phase. Good stack quality allows the sheets to be automatically processed and helps minimize waste through less breakages. 
 
Optimal stacking considers each sheet’s characteristics and adjusts the whole handling process accordingly. The categorization is done based on sheet length, width, quality, thickness and moisture content. The sheets can be stacked into 1-6 or even more stacks depending on their end use, and even randoms can be handled efficiently.  
 
In vacuum belt stacking, the sheets are transported using vacuum gaps: Suction lifts the sheets to the conveyor belt. When the sheet is above the right stacking platform, a kicker arm releases the sheet from the belt and the sheet is stacked accurately onto the platform. The closer you can lift the platforms to the conveyor belt, the shorter the drop will be and the faster and more evenly you are able to stack.  
 
You want to use as little suction as possible to minimize the installed power of the suction system, but also minimize the sheet drop height without sheets being sucked back onto the conveyor. From the environmental side, the less suction you use the quieter the stacker is, and the less sawdust will circle in the air. 
 
Raute stacker solutions have a flexible structure and can be used from simple stacking needs to multiple stacks for wet or dry, composed or patched veneer. Work safety is top of the line with integrated service platforms. All maintainable parts are visible making the service quick and easy.  
 
Our new stackers have a reduced power consumption of up to 30% per stacked m³ compared to our older models. Raute Stacker R7 has a patented vacuum box structure that allows you to optimize suction need, suction box position and dropping height, making even stacks from varied sheet sizes in high-capacity lines. Raute Stacker R3 has a compact modular structure with electric operation that is perfect for small capacity lines.
