Sorting line for Sepa´s the existing finger jointing line!

Sepa adds an automated sorting line to the existing production

After the Finger jointing line installed in 2016, Sepa made another big investment. Replacing the existing old-fashioned, labour intense sorting, line with a new fully automated one.

The new sorting line has a vacuum destacking and infeed system to the 400 mm wide planer. A bandsaw just behind the planer gives flexibility for different new products.
A scanner with AI learning network is checking for defects the customer has "learned" the machine to recognize. Together with the proof load bending machine, the line delivers
high strength timber for the following finger jointing process. Defects to be removed are marked by a line of luminescent ink, later detected by the X-Cut in the finger jointing line.

The line sorts to 3 grades C24, C30/35 and C45 also rejected boards. The 3 stackers put the packages on the roll conveyor to the strapping machine. After this packages are transferred directly to the finger jointing hall or to the external storage.
