Easy to use interface with full automatic functions The press relies on photo recognition and sofisticated hydraulics

Pre fixing before transportation to press unitStops are automatically positioned and timber inserted

SF022 AutoEyeTruss system is a system developed for automatic production of roof trusses. The system combines high capacity with high industrialized quality.

The automatic press visually identifies the roof truss and picks, places, positions and presses the nail plates to the roof truss automatically. The pressing force is adapted to the nailplate, thus the pressing result is perfect.

The system can handle any shape of the roof truss and is working with accordance to Eurocode 2010.

Timber is placed by 2 operators, the placement and position of the timber is guided by the puck tables and laser shape function.

A nailing bridge automatically nails corrugated nails in all joints and marks the roof truss with production data using a ink jet.

The pucks are released and the roof truss is automatically lifted and transported to the next station (�).

The roof truss is transported towards the automatic press.

The press picks nail plates from the right nail plate container, the system has 30 contain-ers of various sizes of nail plates, and feed the nail plates to the press. The press visu-ally identifies how the roof truss and joint is positioned and places the nail plates exactly on the right position relative the joint regardless if the timber is not 100% straight. The press presses the nail plates with the exact pressing force making the result perfect. When all the joints are processed the roof truss is fed towards the next station.

The roof truss moves through the roller press as an extra quality check (option).

The roof truss is automatically stacked. When a complete package is packed the opera-tor bundles the roof truss package and places the package on a truck.

The AutoEyeTruss System can handle and produce any shaped roof truss within the defined limita-tions in dimension, classic shaped or scissor shaped roof truss does not matter.

The production cycle is 11 seconds per pressing point or 13 seconds with 80% utilization. This gives approxi-mataly 187 000 roof trusses annually when producing in 3 shifts for normal sized roof trusses.
