Broken screen detection unit
This special unit controls the integrity of the silk screen. It detects in automatic the presence of ink spots on the printing area. The broken screen detection unit is installed immediately after the printing machine.
The device uses high resolution video camera and rolls with contrast illumination to detect ink marks. In case of ink leakage, the lower surface of the glass will be marked and consecutively the rolls of the inspection system. The camera spots the mark and sends alarm.
The advantage of this system, compared to traditional systems is that its ability to detect the leakage is not limited by the position and the dimension of the screen breakage.
Logo Print System
The logo print system can be either mobile (attachable to the printing machine) or stand-alone solution with a conveyor.
In the first case, the logo-print head, will be installed above the printing bridge, and connected to a dedicated socket. It will be managed by the PLC of the printing machine. The installation and removal is very easy and takes few minutes.
The adjustment of the logo print position and the screen frame is manual. The pressure and the speed can be set through the recipe menu of the machine.
The movement of the squeegee and flood bar is by pneumatic cylinders.
In the second case, the system consists of a conveyor with pin centering system equipped with sensors for correct glass positioning and the logo print head.
The system is commanded by the operator panel of the printing machine.
Automatic screen alignment system
This system is engineered to facilitate and speed up the work of the operator during format changeover. The time can be decreased up to 70%.
The automatic screen alignment is performed with two mobile cameras situated under the printing table, screen motorized tuning and dedicated software. The screen register is performed utilizing reference markers on a master glass which are brought into collimation with the respective markers on the screen. All set up data is stored in the PLC of the printer
The operator tasks are reduced to the insertion of the screen in a proximity position to the cameras, start and supervision of the operation.
Once the correct position is reached the screen will be blocked to prevent further movement.
Automatic Asymmetrical Glasses Centring System
With Cugher Automatic Asymmetrical Glass Centering System it is possible to register glasses with complex shapes, size ranging from 100×200 mm to 1300×2500 mm.
The register system is composed of six pins. Depending on the special request, all pins can be motorized or just three of them, while the other three pneumatically driven.
The set up parameters for each glass model are recorded in the recipe system of the printer.
The pins closing sequence can be defined through the operator panel.
Vertical visual inspection
The vertical inspection station is used to check the quality and the precision of the printing. It does not require stopping the process, since it is positioned offline.
The base of the inspection system is a roller conveyor with tilting arm-system. The tilting arms are equipped with automated reference pins. They lift the glass in vertical position at 70° angle. The upper part of the structure consists of a mobile screen with neon or LED lamps. It lowers behind the glass and lights up to enable the operator to carry out the inspection.
