Printer G Series & Printer J Series
We have developed two series of printing machines, with different levels of automation, able to satisfy each production need.
The G Series, with centring out of the printing table and the J Series for big formats, with centring directly on the printing table. Both can be connected in line with dryers for curing of the ink, using UV or IR technology, optionally chiller units for low glass exit temperature are available.
G Series and J Series
The Cugher silk screen printing machines are able to print on symmetrical, asymmetrical, single, double and paired glasses, with standard dimensions up to 2500×4000 mm and thickness varying from 1,4 up to 10 mm.
We have achieved significant performances:
• Productivity Up To 620 Pieces/Hour
• Print Repeatability Precision of +/- 0,08 mm.
G Series – Shuttle Transport System
The G Series printing machines transport the glasses through a shuttle with two independent cross shaped holders and centring out of the printing table. This solution enables reaching the maximum speed of the printing process for glasses with small and medium dimensions.
The system consists in one cross shaped holder with a vacuum cups system. The glass is collected by the walking beam while it is still in the centring device of the inlet conveyor; thanks to this operation it is possible to transport the glass with great accuracy. No further glass registrations are necessary before the printing process.
J Series – Belt Transport System
The J Series provides transport through a flat belt conveyor designed for glasses with medium and large dimensions, as well as for drilled glasses.
The glass sheet arriving from the entry conveyor is transferred to the center of the printing table through motorized belts.
The belts will lower to printing table level, centring procedure and printing process will be performed, then the belts will lift for glass transportation to the exit synchronized conveyor.
Logo Print Station
The Logo Print Station is a special equipment composed by a booking conveyor and a logo print system that, working jointly, are able to center and print the logo on the underneath glass.
The movement is given by pneumatic linear guide.
It is possible to adjust the squeegee and flood bar speed independently.
The up and down vertical movements of the Squeegee /Flood bar group are obtained by dedicated cylinder.
The Logo Print Station is equipped with its own PLC.
Zero clear border printing capability: Edge to Edge Systems
CNC Suction Nozzle System
The Edge to Edge system is suitable to realize silk printing on flat glass up to the edge of the glass. The system is very flexible and offers an extremely short cycle time. The structure holds and transports a dedicated suction nozzle which removes the extra ink from the screen avoiding unwanted dripping of ink on the glass edges.
The Edge to Edge Suction Blade is a mechanical structure moving on the same guides of the squeegee/flood bar group, moved by the same motor. This structure is mechanically connected to the squeegee/flood-bar. The system offers an extremely short cycle time.
Logo Print Head
The logo-print head, can be installed on the printing machine, above the printing bridge. The printing cycle is automatic and controlled by the operator touch panel. The movement is given by pneumatic cylinders. It is possible to adjust the squeegee and flood bar speed independently.
Broken corner detection unit
The inlet conveyor can be equipped with a Broken glass corner detection system that will alarm and stop the printing machine, to avoid serious damage to the screen and to the printing machine, in case that a glass with broken corner has been detected.
