STEFANI \ MAHROS Evolution SB \ Brush

MAIN FEATURES:

Automatic loading and unloading of panels in stacks;

Automatic evacuation of service panels upon loading

Automatic management of service panels / pallets upon unloading;

Possibility of manual loading / unloading of panels for special needs

(e.g. rework, urgent pieces, etc.);

Longitudinal and transversal squaring and/or squaring-edgebanding;

Execution of blind and/or through milling in the longitudinal and/or transversal direction

Possibility of quality control with operator of the first panel of each batch after SQB 2;

The operator must enable the 1st piece quality control mode on the SPV before

processing each batch:

The supervisor commands the entry of a single panel into SQB1 + SQB2 which will stop on the

outlet belt conveyor at SQB2 for quality control by the operator.

If the panel is to be rejected, the operator presses the appropriate “REJECT” button and the

supervisor brings in a second test panel.

If the panel is good, the operator puts the panel back on the belt conveyor and starts the

production with the appropriate button.

Random quality control

It will be possible to activate this function by means of the supervisor. Given a settable number of

panels, one will be extracted from the line for quality control, to

allow extraction a gap of about 10/12 seconds will be created between the

panels.

The panel can be reintroduced into work at the end of the order by pressing

the appropriate button.

Provide a button for the start of edging from the button panel on the quality control

station and from the button panel on SQB1

TYPE OF PANELS THAT CAN BE WORKED:

Chipboard / MDF panels; Raw panels with a density greater than 650 kg/m3,

honeycomb panels with a perimeter frame of at least 30 mm thickness and already squared, without

protruding veneer.

· Coating / edges:

o melamine, CPL, HPL (no protruding coating on incoming panels);

o Opaque surfaces / edges: For opaque, glossy and film edges refer to the

samples supplied by the customer.

· The panels being processed must have edges with straight sections of a minimum height compatible with

the height and position of the guides and copiers of the machine work

groups and automation of the line (no inclined sections and/or small thickness flaps, etc.);

· The quality of the processing of any through-milling on the 2nd line is not guaranteed with

the intervention of a single spindle moulder (possible chipping or breaking of the edges);

· Straight or inclined milling must be compatible with the maximum removal, the

working edge and the overall dimensions of the spindle moulder units of the squaring

edgebanding machines;

· Any panels with particular characteristics (e.g. milling, slots, large notches,

etc.) must be tested in advance on the line to verify the possibility and quality of

processing;

· Other characteristics of the processes according to the specifications of the individual machines;

TYPE OF EDGES AND MAIN PROCESSING CHARACTERISTICS:

· Removal in squaring longitudinal/transverse (from each side): max. 500 mm2,

with excess material in width from 1 to 10 mm;

· Panel protrusion with respect to the squaring-edgebanding belt (from each side):

o 1st of line: electronically variable by control from 35 to 90 mm;

o 2nd of line: fixed at 35 mm;

Milled distance from edges:

· SQB1 min 5mm (blade excluded), max 75mm without vertical copiers (blade included) 45mm

with copiers

· SQB2 min 5mm (blade excluded), max 20mm (blade included)

· Glue type: EVA / Polyurethane with coating on the panel;

· Edge types: straight (no shaped/postforming) in roll (no strips/slats);

or edges as per samples provided by the customer.

o Thin: supported paper 0.3 / 0.7 mm, melamine 0.4 – 0.5 – 0.6 mm, PVC 0.4 – 0.5 –

0.6 mm 0.8mm;

o Thick: PVC, ABS 1 – 1.5 – 2mm- 3 mm;

· Edge finish: thin chamfered 20°; thick radiused R1- R1.5 – R2 mm;

The quality and finish of any different radiuses (e.g. R1.2 – R1.8 mm) is not guaranteed;

Maximum edge height compared to panel thickness = lower part of the panel 1.5mm upper part of the panel from +2 to +3mm. Example with a panel thickness of 18mm Edge height = 21mm

Other characteristics of the processes according to the specifications of the work groups of the individual machines;

SIZES OF THE PANELS THAT CAN BE WORKED:

Min./max. length : 230 – 3200 mm

Min./max. width: 225 – 1200 /1250* mm

*for panels with this width the introduction of the stacks at loading must be equal to +/-

10mm

Min./max. thickness: 10# – 60 mm

Maximum weight of individual panels: 60 Kg

#minimum thickness for use of mechanical detacher at loading: 12 mm

#minimum thickness with edges with finishing thickness R=1mm: 10 mm

#minimum thickness with edges with finishing thickness R=1.5mm: 12 mm

#minimum thickness with edges with finishing thickness R=2mm: 13 mm
