The complexity of this panel saw lies in the fact that it incorporates not only two cutting axes but also a multi-blade saw, all controlled by a single PLC.
The integration and interaction of these three cutting types make this angular saw unique in its class.
ARCO INTERNATIONAL’s strength lies in creating a synergy between a series of machines that would typically operate separately and in sequence.
No. 4 structures made of solid, pressed and welded sheet metal. Equipped with steel rollers, motion is transmitted through closed chain rings. The roller-conveyors are complete with side cover for chain protection. Includes intermediate rollers for protection.
Electronically controlled screw lifting table, no pit required. The use of worm screws for table elevation ensures precise adjustment, smooth movement, and provides safety against accidental falls.
The elevation is achieved using a rotating screw mechanism, resulting in lower maintenance costs. The rollers feature a toothed pinion at one end and are powered by a gearmotor and chain, mounted within the table frame.
The unit consists of a robust tubular crossbeam for transferring the portion of the stack to be processed from the loading table to the cutting machine. The crossbeam slides on two parallel shoulders, equipped with hardened steel rollers and steel guides. The double T-shaped structure of the supports ensures high rigidity.
The positioning of the pusher is electronically controlled. The pusher drive is powered by a motor with an inverter.
The work surface of the panel-saw is made up of a table coated with scratch-resistant material (nylon brushes) and includes a pneumatic device for the front alignment of the stack. On the sides of the table, there is an automatic device, electronically controlled via PLC, for positioning the panel in either the longitudinal or transverse direction. Using two special clamps mounted on motorized carts, the previously aligned stack is rotated 90°. The rotation clamps move along two orthogonal axes, performing the rotation. This rotation can occur in both directions, allowing the stack to be returned to its initial position, after performing any pre-cutting if required.
The unit consists of a robust tubular crossbeam on which 6 clamps are mounted to secure and position the panels during processing.
The crossbeam slides on two parallel shoulders, equipped with hardened steel rollers and steel guides. The double T-shaped structure of the shoulders ensures high rigidity.
The positioning of the pusher is electronically controlled.
The position of the pusher is detected via an encoder mounted on the motor. This highly precise device works in combination with a system to eliminate backlash between the pinion and rack, ensuring maximum precision.
The pusher is driven by a brushless motor. The digital control of the brushless motor allows continuous speed adjustment of the pusher from 0 to 90 m/min. Brushless motors provide optimal torque performance even at low speeds, delivering higher power than traditional motors while offering maximum durability and reliability, as they are not subject to component wear.
4500 mm CUTTING AXIS WITH TWO BLADES FOR BIDIRECTIONAL CUTTING
The assembly consists of a robust bridge structure, made of steel, which is normalized after welding. Mounted on this structure, positioned above the work surface, is the tool carriage. The carriage slides on high-precision, tempered guides that ensure perfect repeatability of movements, with a guarantee of 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.
A gear and rack coupling ensures the parallelism between the pressure beam and the work surface under any working conditions.
Each blade is equipped with an independent motor to allow bidirectional cutting, resulting in increased productivity while preventing chipping of the edges of pre-edged panels during the cutting process.
The stroke of the cutting units is controlled by two actuators driven by two Brushless motors with respective drivers.
Two pressure beams slide vertically on guides integrated into the work surface, with the vertical movement provided by four pneumatic cylinders with adjustable pressure.
