PVB LAYING AND ASSEMBLING SECTION

LAMINATED GLASS LINE

 

OPERATING:

After first glass coming to assembling table, it starts manual PVB laying on first glass (PVB laying can be made automatically through plier system); when right PVB length is reached, automatic cutter cuts PVB film; then second glass, after the start given by the worker, is picked by suction cups aerial system, it comes to assembling table and it is put on the first glass along the same axis. After assembling, panel is trimmed manually by worker and it is carried through special rollers to the heating and pressing section. To increase versatility and for off-line production, it is planned an additional unwinding, laying and assembling zone to work "not standard" glass (for example curved, bended glass, drilled glass, special shaped glass) that will be laminate through vacuum sack system.

FEATURES AND TECHNICAL DETAILS:

  • Automatic PVB laying (OPTIONAL) through plier, that picks film and lays it on length size that is set, then it will be cut automatically through cutter; with automatic PVB laying all operations are automatic: picking and coming to assembling conveyor of the first glass, PVB laying on it, PVB cutting according to the lenght needed (set), picking of the second glass and assembling with the first glass.
  • Unwinder with 4 (or more, up to 16) motorized PVB roll bearings; different thickness, width, colour PVB can be used (max diameter: 500 mm); with 4 (or more, up to 16) PVB interleaf rolls; through this system all PVB rolls are always ready to be used and you don't lose time in the PVB roll choosing; with more than 4 PVB roll bearings we suggest to put aerial unwinder, over assembling section, with specific painted iron frame, platform to walk around, and ladder; unwinding and winding of the PVB film and interlayer are automatic and speed is adjustable electronically; automatic pneumatic cutter for PVB cutting operation on length side; automatic cutter on width side of the PVB film (OPTIONAL), cutting operation is done automatically during the PVB unwinding, the cutting size is adjustable manually with the help of a metric scale.
  • Antistatic bar on PVB unwinding system(OPTIONAL) to keep film and glass sandwich clean, and to avoid problems during PVB laying: PVB film has antistatic charge, that can cause bending of the film during laying (specially with automatic laying, where workers don't check and adjust it), this can create some problems during heating and pressing process.
  • Assembling table with two shaping on one side, to facilitate small glass working; with tipping device that throws down a part of assembling table, to carry out worker crossing from one side of the table to the other, to facilitate unwinding/laying/assembling/trimming; lights to control glass cleaning under assembling zone.
  • Trimming system for small glass, constituted by a platform with free rotating spheres, that lifts through pneumatic mechanism controlled by specific pedal keyboard; this system is very useful and make trimming easy; rotating the glass panel, only one worker can make operations.
  • Electric crane and specific trolley facilitate loading and unloading operations
    of the PVB rolls on the uncoiler.
  • Additional unwinding, laying and assembling zone to work "not standard" glass (OPTIONAL), with 2 motorized PVB rolls bearings, different thickness, width, colour PVB can be used (max diameter: 500 mm); with 2 PVB interleaf roll bearings; unwinding and winding speed is adjustable electronically; with automatic cutter for PVB cutting operation on length side; with assembling/trimming table, painted iron made, with wheels to move it, surface for PVB leaning made by specific material for application; the table is also equipped with a structure in painted iron to hang up the PVB
    sheets already cut and prepared for laying.
  • PVB pre-cut system (OPTIONAL) to prepare the PVB foils cut at size and ready to be positioned on the glass for the lamination; this device is composed by PVB unwinder, automatic cutters (on width and on length side of the PVB film), PVB film automatic laying system, table to stock PVB pre-cut foils; the worker selects the kind of the PVB film and the number of pieces to cut and prepare, then machine automatically unwinds, lays on the stocking table, cuts the needed PVB foils; PLC controls the operations.
  • Conveyors with independent drive, motoreducer and inverter to adjust working speed.
