Float cutting lines
Float cutting lines to manage the glass ribbon from the exit of the annealing lehr. Bottero Optimization system interfaced with the quality inspection system optimizes the cuts according to stacking positions and glass quality defined in the production table. The lines can be classified according to their daily production capacity, starting from 250 T/day to 1200 T/day. Glass production for electronic application (ultrathin thickness starting from 0.25 mm), for automotive application (thickness from 1.6 to 6 mm) and for architectural application (thickness from 3 to 19 mm).
Cutting heads with latest-generation electromagnets for reliable pressure control and accurate clean cuts, for glass thickness from 0.25 mm for electronic application to 19 mm for architectural glass. Different cutting solutions from Jumbo sizes to small cut sizes (410 x 410 mm) thanks to the presence of longitudinal bridges with several cutting heads and to #5 cross cutting bridges. Cut lubrication system with focused oil flow straight on scores enables a minimal quantity of lubricant on glass and it’s also suitable for high-evaporation oils.
“X” breakout system with contrast wheels for plate thickness from 1.6 to 19 mm. Dedicated systems for glass thickness above 19 mm. In this position a fast scrap eliminator can be installed.
Selvedge machine / trim deck
Transport conveyor system and breaking wheels for trim removal. The length of transport conveyors and the number of breaking wheels depend on glass dimension, on the number of trims and on the possibility of managing different glass widths at the same time.
“Y” dynamic breakout and separation
“Y” dynamic breakout groups and separation rolls installed under the glass transport level. The control system automatically positions the breakout units under the glass scores and it breaks and separates lites with high repeatability and speed in dynamic during the glass transport.
Geometric inspection system
Geometric inspection system to check the glass after the breakout areas. The system verifies the glass during the transport and sends the inspection result to the line control. The line control decides to send this glass either to the cullet or to the stackers area.
Drop conveyors for glass plates rejection
Transport conveyor systems with the possibility, by a drop function, to send to cullet the defective glass plates. The system can be single zone, double zones or selective zones according to the line configuration.
Availability of different stacking solutions according to glass dimensions, glass contact surface, glass handling in warehouse and cycle time:
• For Jumbo sizes and special sizes up to 18 m.
• For small sizes till 410 x 410 mm.
• For air and/or tin side stacking.
• With traditional equipment and robot systems with pick on fly.
• High speed stacking system.
