Robotic Resin Line

The production capacity our plants varies from a less of 6 slabs/h to a maximum of 70 slabs/h.
The level of automation of the plant line depends on Customer’s requirements, whereas the heating systems of drying and catalysis machineries can be equipped with gas or electrical devices.
The plants features are not pre settled, therefore each line is designed according to the Customer’s demands that is about the useful space in the company the needed production capacity and the material characteristics.
The idea of automating the application of resin and more generally chemical products on natural stone slabs without losing the quality level typical of the craftsmanship of manual
operation, was born in 2013 and materialized two years later in the first specimen of GALILEO By Prometec.
Two years after the first installation, GALILEO did not disappoint expectations, but has been enhanced with many features thanks also to the contribution of so many customers who trusted us in this great potential technology.
Today’s GALILEO is a machine that, in spite of its intrinsic complexity, has achieved great reliability, ease of use and high quality of application thanks to the continuous development of the end-effector coordinated with a reader capable of providing very precise slab profile information.
It is also able to rapidly adapt itself to the most different needs of the work type, the required production per hour, material characteristics, epoxy blends and the type of reinforcement net.
VERSIONS
* GALILEO HIGH PERFORMANCE
able to process a slab per minute
• GALILEO HIGH QUALITY
capable to manage complex tasks with high accuracy, such as the application of reinforcement nets characterized by high absorption of the mixture
• GALILEO HIGH COLOUR
the optimum solution for pigmentation, by means of a suitable dosing system, of marble or granite slabs
• GALILEO HIGH VISCOSITY
specially designed for automatic and controlled application of dense and viscous mixture like mastic
WORKING CYCLE
The GALILEO processing system is divided into two
separate phases:
1. THE SCANNING PHASE during which a 3D model of the slab is made. This makes it possible to detect with extreme accuracy the thickness at every point, the perimeter of the slab and the presence of hollow spots classified according to suitable criteria in order to then retouch them where necessary.
2. THE STAGE OF APPLICATION OF THE RESIN AND SUCCESSIVE RITOUCH WORK IF NECESSARY is done by an anthropomorphic robot by an anthropomorphic robot that receives all the trajectories for applying the resin and the location/characteristics of the fractures to be restored from the scanning machine.
INNOVATIONS
Accuracy and repeatability of the work
Predictability and repeatability of the quantity of mixture per square metre worked
Replacement of the human operator for the resining and retouching cycle
Drastic reduction in the resining and retouching cycle time
Saving in the two-component mixture (approximately 30% less)
Lower cleaning and maintenance costs because no spray
Even application with consequent advantages during the polishing phase
Drastic reduction in the man-machine interaction:
fewer harmful substances for man, less probability of accidents,greater production efficiency
Significant reduction of resin vapours in the workplace

BRETON RESINDRONE: ROBOT FOR AUTOMATIC RESIN TREATMENT OF SLABS

SIMPLICITY FIRST: This was our watchword as we developed our robot for automatic resin treatment of slabs.

We have designed it by taking a 5-axis interpolated machine as a model, a technology now well-established and widespread, and by inventing a new application.

SIMPLICITY as reliability: the mechanics of a 5-axis milling machine can withstand stronger strains than a small mass-produced humanoid machine.

​SIMPLICITY as precision: precision and quickness in following the predetermined resin distribution paths within the slab perimeter with a cycle for redistributing the resin in excess sitting on the edges.

SIMPLICITY as user friendliness: changing the parameters and the working cycles is easy and intuitive.

SIMPLICITY as environment friendliness: Thanks to the technology that mixes the resin different components in the last centimeters of the distribution duct, cleaning is easy and quick, it does not need solvent, reducing environmental impact.

SIMPLICITY as easy maintenance: in the unlikely event of system malfunctions, Breton Service remotely connects to the machine by implementing a hot-line problem solving process. The possible intervention of an after-service Breton technician can easily fix malfunctions whether she is in India, China, Brazil or anywhere in the world.

SIMPLICITY as full optional: ResinDrone can be equipped with various accessories, for example one for automatic roller cleaning or replacement, in order to work automatically for several hours.

An anthropomorphic robot with 6 axis, placed on the roller bench side, automatically performs the application of the reinforcement net and of the resin.
The first operation consists of the reinforcement net application.
The robot, by means of a gripper system, unrolls the net required length
which is subsequently cut and laid on the slab surface.
An optical reader has previously measured the slab.
A rotating plate with brushes, equipped with resin mixer, approaches the middle of the slab and releases the right resin quantity. Then the robot starts the automatic distribution stage by means of a spatula, spreading and handing out the required quantities of resin, which can be programmed on the control panel through colour touch-screen monitor.
The components come from thermo-controlled tanks equipped with mixers and they are separately pumped up to the mixer nozzle which is installed on the automatic distributor final part.
A washing pipe comes into action when the resin application cycle stops for a period which is longer than the resin gelling time.

Plants for the application of the reinforcement net on ceramic slabs.
Manufacturing big and very thin sintered stone slabs has led to the need to apply reinforcement systems as to prevent any damages in case of accidental breakages. When it comes to sintered stone slabs, it is implied to talk about large productions and therefore very reliable and fully automated plants. In order to meet such requirements, SIMEC has developed a specific solution based on the use of anthropomorphic robots, along with ovens for the catalysis of resin with continuous cycle already used for years in the field of natural stone and able to fully meet the speed reliability and flexibility requirements, achieving productivity up to 1 slab per minute, with particularly low running costs.
