PRISMA 16+16+16 CS

The new Prisma 16+16+16 CS has been successfully installed and tested at the Laurent Perrier Wine Cellar in Tours Sur Marne, in France, with a production capacity of 12,000 bottles per hour.

The machine was ordered for its specific feature of smoothing and positioning capsules on spumante bottles, in line with the cage eye so that it is at 90° with respect to the logo printed on the capsule.

After extensive research by the Nortan technical office into the various solutions, the best one was finally submitted to the client for their approval before passing onto production.

The first turret has 16 workstations, each one comprising two centring units and the first an OMRON visual sensor and the second a Datasensor UV photocell.

The vacuum system on the centring head lifts the capsule off the bottle so that the cage eye is clearly visible, enabling the camera to identify the position, the bottle is then orientated while the centring head positions the capsule. When the bottle and capsule are correctly orientated, the capsule is placed on the bottle and a deformable bulb presses it lightly to avoid movements during its passage to the smoothing turret.

The bottle, with the capsule positioned with the cage eye, is carried to the second turret where it is orientated so that the logo on the capsule is centred between the folds. A pincer star picks the bottle and places it on the third turret where the capsule finally smoothed.

The machine is equipped with a star expulsion and vacuum picking system, which expels any bottles without cork or cage and places them on the recovery conveyor belt.

This cutting edge machine is equipped with the latest most innovative solutions and is yet further proof of Nortan’s ability to constantly extend its product range, to respond to the varying specific needs of its clients for highly efficient and precise machinery.

The Nortan guiding philosophy has always been to consider each new machine as a challenge projected towards the future, learning from the experience and building new strategies to apply to the new products so that they are always one step ahead of the times.

ENERGY-SAVING THERMAL PRISMA

After accurate research and experimentation, Nortan is pleased to introduce the new Thermoflex thermal heads.
In this new and revolutionary system of thermo-retraction, the head’s up and down movements are entrusted to a particular pneumatic cylinder that is long-lasting and resists high temperatures, developed in collaboration with the Airon company in Rovigo.
Currently, all thermo-retraction systems work with a fixed cam meaning how long the head takes to go down depends on the machine’s speed.
During the minimum-speed phase the bottle stays within the head for too long, risking the capsule breaking, while at high speeds the opposite can happen.
Therefore, it is impossible to set up the machine (ventilation pressure within the head and temperature) for optimal smoothing quality when the line’s speed is not constant. In the new cylinder system the thermo-retraction is independent from the machine’s speed and the head’s descent time can be varied by the operator with the touch screen panel.
Thermo-retraction can also happen when the machine is in the manual function (push-button panel) or with a continual production block in that the head will descend just once and in the point indicated by the PLC.
Therefore, the function is simple and, above all, very advantageous from the economic and quality points of view.
This system has ensured us a noteworthy saving in energy consumption as the thermo-retraction temperature is around 200°C compared to the previous 300/400°C and the quantity of air used has been dramatically reduced as we use just one, 2-bar pressure electro-valve.
This new system is already standard in the Prisma 120 and later models, while it is optional in the smaller models.
Various machines with a production rate of 8,000 bottles/hour to 20,000 bottles/hour have been built in Italy, Germany, Spain, France and South Africa with no set-up problems and with results during the hottest period of the year that are well beyond expectations.
Tests carried out by Nortan checking both the worst heat conditions and lack of lubrication in the sliding columns have guaranteed the pistons a life of around 10 million cycles, without replacing the washers.
Broken capsules and bottles having to pass through more than once due to bad thermo-retraction are a thing of the past.
Once again, Nortan has shown itself to be at the avant-garde of technology, with its eyes to the future and the client’s needs.

PRISMA 8+8 CC+S

The new Prisma 8+8 CC+S has been installed and tested at the CAVES ST. REMY-DESOM s.a r.l. wine cellars in Remich – Luxemburg. This one-of-a-kind machine, which follows a previous machine installed in Italy, is able to position and smooth out the capsules on bottles of spumante while the eyelet to open the cage remains visible.

Conceived, designed and made by the innovative Technical Staff of Nortan, the machine is able to produce 5000 bottles per hour and granting the customer with considerable savings, since before they had to place the capsule manually, wasting time and personnel.
A conveyor device moved by a chain system collects the capsule from the distributor and moves it to the turret. Now, by means of a servo mechanism, the capsule is collected by a special head that orientates the capsule by means of visual sensors. After, the head prepares a slit where the eyelet is going to be inserted and finally rests the capsule on the bottle. The eyelet, slightly inclined outwards, passes through a slit and keeps its position outside the capsule.
The bottle is moved to the second turret by means of a star where the capsule is centered and smoothened.
Once again, Nortan has extended its range of products to meet the needs of its customers, thanks to machines that are designed in accordance with the latest technology.
