One of the clearest examples of our ability to innovate is represented by our panel saws, capable of cutting virtually any type of product with precision and reliability. When one of our customers requested an automated and fully integrated system for cutting panels in the furniture and food packaging sectors, we embraced the challenge.
Apparently an impossible challenge, as no one had ever produced a 3-in-1 panel saw, our designers met this challenge by creating a tailor-made solution thattransformed their production process.
A device that allows for the loading of panels with a thickness ranging from 1.8 to 6 mm, ensuring continuous operation and reliability in the automatic loading process from the lifting table to the panel saw.
A chain transport device for pre-loading with evacuation of the sacrificial panel. Arranged on two levels, it is designed to receive the new stack destined for the lifting platform and evacuate the sacrificial panel in the same direction.
Electronically controlled screw lifting table, requiring no pit. The use of worm screws for the table's ascent allows for precise adjustment and smooth movement, while also providing safety guarantees against accidental drops
A selection device designed to shift a stack of sheets from the main pile. A group with push wedges is positioned under the selected stack. After a short lifting stroke, the wedges push, moving only the selected stack. The pushing unit consists of a robust tubular crossbar on which a set of separating wedges is mounted, which are inserted beneath the selected stack. The crossbar moves via hardened steel rollers along two parallel sides equipped with steel guides. The double-T structure of the side ensures high rigidity. The positioning of the pusher is electronically controlled. The position of the pusher is detected using an encoder mounted directly on the motor.
The work surface of the panel saw consists of a table coated with scratch-resistant material. Its purpose is to support the stack while maintaining perfect flatness, ensuring cutting precision.
The loading table is equipped with two panel alignment devices: two motorized movable crossbars. The front aligner is fixed and located beneath the pallet, with the stack being pushed against it by the positioning pusher. The lateral aligner is mobile and is electronically adjustable based on the loaded panel size. Their purpose is to ensure the perfect formation of the stack to be cut.
The positioning pusher group consists of a sturdy tubular crossbar onto which clamps are mounted for the gripping and positioning of panels during processing operations.
The group consists of a solid steel bridge structure, normalized after welding. This structure is positioned above the work table, supporting the tool carriage. The carriage moves along high-precision tempered guides, ensuring perfect repeatability of movements with long-lasting durability. On the tool carriage, a column is fixed with precision guides, where two blade motors slide vertically and can be engaged individually.
Each blade is equipped with an independent motor to allow cutting in both directions, thereby increasing production and preventing the chipping of the edges of pre-edged panels during cutting. The stroke of the cutting units is controlled by actuators managed by motors with corresponding drivers."
The pusher group consists of a sturdy tubular crossbar with 5 arms mounted, designed for transferring the bundle from the mobile pickup table located after the longitudinal cut to the sliding plane of the cross-cutting panel saw.
The crossbar slides, using tempered steel rollers, on two parallel side supports equipped with steel guides. The movement is powered by a gearmotor controlled by an inverter.
The work platform of the cross-cutting machine consists of a table coated with scratch-resistant material, beneath which slides a mobile crossbeam equipped with 5 pneumatic aligners. These aligners automatically disengage after transferring the material to be cut against the reference guide. The crossbar that carries the aligners is motorized and slides on ball recirculation guides to position itself at the preset measurement, thereby optimizing time.
The pusher group consists of a sturdy tubular crossbar on which five clamps are mounted for the clamping and positioning of the panels during processing.
The assembly consists of a solid steel bridge structure, normalized after welding. This structure is positioned above the work table, supporting the tool carriage.
Each blade is equipped with an independent motor to allow cutting in both directions, resulting in increased production and preventing chipping of the edges of pre-edged panels during cutting.
The stroke of the cutting groups is controlled by two actuators managed by two Siemens motors with their respective drivers.
Crosscut saw discharge table with motorized belts and liftable platforms, designed for the discharge of trimmings. Length: 2200 mm, width: 2600 mm, with synchronous belts for transporting strips while maintaining alignment. Motorization with variable speed via an inverter, ranging from 16 to 40 m/min. Tilting device for the opening of the trimmings discharge hatch.
A double transfer system with a clamp is designed to transport the strips produced by the cross-cutting process close to the multi-blade saw. The dual device works alternately, allowing one to pull the strip while the other performs the return stroke to the pickup position after depositing the strip. These devices are powered by a gearmotor with a brushless motor to handle the transport dynamics.
The purpose of the liftable platform is to raise the strip just deposited so that the feeding pusher of the multi-blade saw can take it over without making unnecessary movements.
The pusher group consists of a sturdy tubular crossbar on which 11 clamps are mounted. These clamps slide on ball recirculation slides to allow for format changes. The positioning of the pusher is electronically controlled. The position of the pusher is detected via an encoder mounted directly on the motor.
The multi-blade saw consists of a base with guides on which 12 cutting tool holder units are installed. The units are movable and can be individually positioned with electric control via a brushless motor and a gear-rack drive with a helical profile. The set tools displacement is displayed on the control panel.
The tool holders feature a pressure system with brushes, which is self-regulating based on the panel thickness. Additional brushes are installed to limit dust dispersion and enhance upper dust extraction. The blades can be engaged or disengaged depending on the cutting pattern.
A motorized conveyor belt, 1000 mm wide and 2200 mm long, for the discharge of the multi-blade saw. The produced pieces are delivered by the clamps to the conveyor, which transports them to the discharge device.
Evacuation of trimmings with a 13-meter conveyor belt, including 10 meters of inclined belt for the evacuation of cutting trimmings and cross-cut trimmings, controlled by an inverter.
The cross-cut trimmings fall into a container placed under the cutting axis and are then translated and rotated by 90° by a special device, pneumatically controlled, which deposits them on the belt along with the trimming waste.
