Successful commissioning of automotive Cutting Lines at Profilglass Salico

Recoiling Section in Combi Levelling and Slitting Line

SUCCESSFUL COMMISSIONING OF AUTOMOTIVE CUTTING LINES AT PROFILGLASS

Following the impressive growth path of our all-time customer PROFILGLASS, Salico has recently delivered and started up two very impressive Cutting Lines along with a Tension Levelling Combi Levelling and Slitting Line & Cleaning Line for applications in the automotive and aerospace sectors. The COVID-19 pandemic did not hinder the teams from concluding the project quickly, efficiently, and successfully

Combi Levelling and Slitting Line

The Combi-line – so called because of its ability to combine Decoiling, Levelling, Slitting and Recoiling – is designed to process a wide range of aluminium coils of up to:

• 25 tonnes with a maximum outer diameter of 2,500 mm. • Strips with a width of up to 2,500 mm, ranging 0.5 to 5.0mm in thickness. • A Maximum Slitting Capacity of 35 slits at a line speed of 400m/min.

Strip Levelling is performed using a Leveller which features a 6-high Cassette design.

Since Slit Shearing is carried out using slitting tools, every time a different tool is needed, the change is carried out automatically with the Auto Slitting Tooling Changeover, which takes just five minutes. Slitting Tools are secured in position by an Auto Locking mechanism designed by Salico. The unit is completed with a Scrap Chopper and Conveyor.

The Auto Slitting Tooling Changeover is complemented by the Robotized Slitting Tooling Setup, featuring the Salico proprietary robotic system.

The Salico Bridle is the perfect complement to the Recoiling area and guarantees a totally scratch-free surface even for most sensitive processed materials. Adjustments to the separator discs is done in totally automatically via a robotic Salico system.

Electrical Cubicles, engineered and manufactured by Salico Automation, are fitted into dedicated climatised containers, which come

with office space and pedestrian & maintenance access doors, installed five metres above floor level, saving space in the rear of the Line.

PVC Foil Application is provided upstream to the Slitting Shear and Paper Foil application in the Recoiling area.

The line ends with an Exit Coil Turnstile equipped with high-efficiency Circumferential Strapping Facility, designed by Salico, which allows for the maximum run uptime of the Line.

Cut To Length Line

The Line allows for the cutting of aluminium sheets of up to 10 metres from coils of 25 tonnes in weight, with an outer diameter of 2,500 mm, a width of 2,500 mm, and thickness ranging from 0.8 to 9.0 mm.

Downstream to the Decoiling function, an Edge Trimming facility removes any jagged or uneven edges, cutting them away from the mother strip. This ensures uniform edges on the mother strip and avoids the chance of bringing debris or contaminants into the machine.

The Levelling Machine, which features a 6-high Cassette design, is provided with no. 2 Roller Cassettes to perform strip levelling across the entire range of material thickness.

The main machine’s features include the Automatic Cassette Change, and positioning of the upper “cassette” half along the “X” and “Y” axis. “Localised corrections” are made in the lower “cassette” and recovery of backlash screws-down into the upper part of the Machine via a dedicated hydraulic circuit, also designed by Salico.

The Salico Rotary Shear, the undisputed leader in the field of Rotary Shears, helps to maximise the performance of the Mega Vacuum Stacker which completes the Line.

The upper PVC foil and the lower paper foil applications are applied upstream from the Rotary Shear.

Non-stop sheet stacking of up to a maximum length of 5,000 mm is performed via two Stacking Platforms working alternatively, while Stop Stacking allows for production of sheets up to 10,000 mm long.

Tension Levelling & Cleaning Line

The Line is designed to process aluminium coils of 1,650 mm in width, weighing up to 12 tonnes, and ranging in material thickness of 0,2 to 2,0 mm.

The Line is a unique two-floor design. The ground level is dedicated to Pre-cleaning and Tension Levelling of the Aluminium strip, and the upper floor is reserved for Fine Cleaning.

The pre-cleaning section is downstream to Decoiling and Edge Trimming. Its functions is to send the aluminium strip to the Tension Levelling Unit free from debris and possible contaminants which might impair the end-quality of the product.

Cleaning of the ground and upper floors is done with the use of alkaline cleaning solutions in the Salico-designed Treatment Cellar.

The Line ends with a Recoiling Section which features a plastic film application on both sides of the processed strip, while a Salico-designed Belt Wrapper guarantees the efficient engagement of the Aluminium strip leading edge with the Recoiler Mandrel. n
