CONCEPT


WHAT IS THE T-LINE?

The T-Line™ is a modular, fully automated production system consisting of the units required for the processing cycle of a given product. It is characterized by a high degree of flexibility and customization. Initially designed for the continuous production of ingots out of refined precious metals, it can be adapted to many other types of applications, according to the customer requirements.

The operations are performed sequentially by moving the product from one point to another of the line. This allows the modules that compose it to be combined and modified according to the specific needs of the process and of the buyer.

WHAT IS AUTOMATION?

Hand production often turns out to be slow and costly. Only with automation of any given operation can one offer a consistently top quality product with greatly reduced outlay. The manual labor previously needed to run the newly automated machinery can now be re-directed to skilled labor activities. Automation is a way to increase productivity and to eliminate routine jobs placing employees in higher value jobs.

THE TIME FACTOR

One of the main distinctive elements of T-Line™ is its flexibility, which allows to integrate new machines and modules in the short and long term even to existing and non-automated machines.

Each module can work as a stand-alone station, so the T-Line™ can also be developed by adding modules over an extended period of time.

BULLION PRODUCTION

Grains production & processing

1) TILTING FURNACE

The operator needs only to load the refined precious metal into the crucible, and then all successive steps are automated. The crucible of the melting furnace has hydraulic tilting.

2) GRAINING TANK

Once melted, the precious metal is poured into a properly holed and heated graphite die. The metal drops into the granulation tank and comes into contact with cold, circulating demineralized water, where it takes the form of spherical grains of various diameters. The water inside the granulation tank is removed, leaving the wet grains ready for further treatment.

3) T-DRYRAY: DRYING THE GRAIN

The wet grains are then unloaded and transferred from the appropriate T-Lift™ belt to the inlet of the T-Dryray™. In this module the grains undergo a drying treatment thanks to their permanence inside an electrically heated steel cochlea. The rotation of the cochlea ensures the evaporation of any water residue present in the grains, also avoiding any oxidation.

4) T-SCREENING: SORTING THE GRAIN

Once dried, the grains are transferred to the T-Screening™ circular vibrating screen where large-diameter and small-diameter grains are separated. They are then transferred to the respective conveyors of the T-Dosing™

5) T-DOSING

La graniglia, opportunamente vagliata per diametro, viene caricata all’interno delle rispettive tramogge.

Sulla base della ricetta impostata, la T-Dosing™ provvederà automaticamente a riempire appositi contenitori con la quantità di grana esatta, assicurando una tolleranza al centesimo di grammo. Tali contenitori vengono immessi su apposito nastro e resi disponibili per la fase successiva. La dosata avviene in tre fasi: macro-avvicinamento al peso target con grane grandi, micro-compensazione con grane piccole e calibrazione centesimale con taglio filo.

6) ANTHROPOMORPHIC ROBOT

The T-Dosing™, like all the other Tera Automation machines, is designed to be integrated with an anthropomorphic robot. In this case it is used to handle containers.

The containers with the grains that arrive on the outfeed conveyor belt are picked up by an anthropomorphic robot that pours their contents inside the molds placed on the Conveyor Chain™ of the melting furnace. Once the grains have been spilled, the robot covers the ingot with its lid and puts the empty containers back into the cycle of the dosing machine.

7) T-BARMASTER™ TUNNEL FURNACE

The mold containing the exact dose of grains is directed at the entrance of the melting furnace by the Conveyor Chain™, that is the conveyor system that ensures the automatic flow of the melting process into the T-Barmaster™. The melting process exploits patented technologies (Pinch Valves™) and guarantees top quality end products with a low management cost and an extremely simple man-machine interface. In particular the solidification phase of the metal is based on an algorithm that guarantees total control.

Ingots finishing

8) DELTA ROBOT

The mold coming out of the furnace containing the solidified ingot is moved by means of a mechanical pusher on a conveyor belt that leads it to the gripping point of a Delta robot. Here the robot removes the ingot lid, extracts the ingot, places it on the template of the T-Brush™ automatic brush and closes the mold again. The Delta is equipped with a vision system that distinguishes ingots that are already perfect from those that require an additional finishing, automatically performed by the T-Brush™.

It then transfers the perfect ingots first to a precision load cell – which checks their weight – and then to the conveyor belt that takes them to the T-Finishing™, while the non-compliant ingots are placed on a second outfeed belt.

9) THE T-BRUSH™ AUTOMATIC BRUSH

If the quality control vision system estimates that the ingot should be polished, the brushing machine will activate automatically.

After a quick cleaning cycle, the Delta robot moves  the mirror-finished ingot on the load cell again to check the weight.

10) T-FINISHING™: INGOT STAMPING AND SERIALIZATION

The compliant ingots are then ready for the application of the logo and the serialization. These operations are carried out automatically by the T-Finishing™ thanks to its rotating table that continuously brings ingots underneath the logo application station (hydraulic press) and serialization station (T-Numbering™).

At the end of the cycle a second vision system captures a picture of the finished ingot.

Of course you can add additional stations, such as laser marking.

11) SCARA ROBOT & CERTIFICATE PRINTER

At the exit of T-Finishing™ a conveyor belt leads the ingots to a printer which is fed by blank or pre-printed cards with the company logo. A SCARA robot places the finished ingots on top of the cardboard on the conveyor belt of the next station so that the marked part is well visible and the certificate can be read by rotating the ingot.

12) T-PACK™: PACKING MACHINE

The ingot with the certificate is packed in a transparent film that completely wraps it. The film is sealed by means of heat and the packed ingot is conveyed to the exit of the machine, where it can be taken by an operator.
