TECHNICAL SPECIFICATIONS General specifications for the squaring and edgebanding line 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. revisions, urgent pieces, etc.); · Longitudinal and transversal squaring and/or edging; · Execution of blind and/or through milling in the longitudinal and/or transversal direction · Possibility of quality control with operator first panel of each batch after SQB 2; The operator must enable the 1st piece quality control mode on the SPV before processing of each batch: The supervisor commands the entry of a single panel into SQB1 + SQB2 which will stop on output belt conveyor to SQB2 for quality control by the operator. If the panel is to be discarded, the operator presses the appropriate “DISCLAIM” 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 launches the production with a specific button. Random quality control It will be possible to activate this function by means of a supervisor. Given a number of panels settable, one will be extracted from the quality control line, to allow the extraction will create a gap between the panels of approximately 10/12 seconds. The panel can be reintroduced into work at the end of the job by pressing the appropriate button. Provide a button for starting the edging process from the keypad on the quality control station and from keypad on SQB1 TYPES 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 30mm thickness and already squared, without protruding veneer. · Covering / edges: or melamine, CPL, HPL (no protruding coating on the incoming panels); o Matt surfaces/edges: For matt, glossy and film edges please refer to samples provided 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 working groups and line automation (no inclined sections and/or small thickness swings, etc.); · The quality of the processing of any milling operations carried out on the 2nd line is not guaranteed with intervention of a single router (possible chipping or breaking of the edges); · Straight or inclined milling must be compatible with the maximum removal, the cutting edge work and the overall dimensions of the spindle moulder groups of the squaring and edgebanding machines; · Any panels with particular characteristics (e.g. milling, slots, large notches, etc.) will have to be tested beforehand on the line to verify their 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 from the edgebanding machine track (on each side): or 1st line: electronically variable by control from 35 to 90 mm; or 2nd line: fixed at 35 mm; Distance milled from edges: · SQB1 min 5mm (excluding blade), max 75mm without vertical copiers (including blade) 45mm with copiers · SQB2 min 5mm (excluding blade), max 20mm (including blade) · Glue type: EVA / Polyurethane with coating on the panel; · Edge types: straight (no shaped/postformed) 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 – 0.6mm 0.8mm; o Thick: PVC, ABS 1 – 1.5 – 2mm- 3 mm; · Edge finish: thin 20° chamfered; thick radiused R1- R1.5 – R2 mm; The quality and finish of any different spokes (e.g. R1.2 – R1.8 mm) is not guaranteed; · Maximum edge height compared to panel thickness = lower part of panel 1.5mm part upper panel from +2 to +3mm. Example with 18mm thick panel H edge= 21mm · Other characteristics of the processes according to the specifications of the individual work groups machines; DIMENSIONS OF WORKABLE PANELS: Min./max. length: 230 – 3200 mm Min./max. width: 225 – 1200 /1250* mm *for panels with this width the introduction of the stacks to the load 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 load: 12 mm # minimum thickness with edges with finishing thickness R=1mm: 10 mm # minimum thickness with finishing thickness edges R=1.5mm: 12 mm # minimum thickness with finishing thickness edges R=2mm: 13 mm LOAD AND PROCESSING LIMITS FOR “STANDARD” AND/OR “CONTRARY” PANELS: · definition of “STANDARD” panel: panel with length / width ratio L / W ³ 1 · definition of “CONTRARIO” panel: panel with length / width ratio L / W < 1 Load and working limits for opposite panels: W / L £ 1.2 (e.g. L = 500 mm W £ 600 mm) NB: the opposite panels must be previously oriented on the incoming stacks in the sense of workmanship
