3 [Graphic Division] From the experience and the productive capacity of Vuototecnica, one of the first companies in Europe that made vacuum pumps and vacuum accessories, a division fully devoted to assist the graphics and printing field originated. A reference reality from engineering to service, able to offer innovative and advantageous technological solutions under all points of view: performances, reliability, life, operational economy. A significant demonstration of the specialist skill of Graphic Division is the new line of products. Among the most representative we offer: PNEUMATIC SUCTION AND BLOWING PUMPS This new generation of very flexible pumps with multiple ejectors, able to suck or blow according to what is required, represents a real technological advancement compared to the traditional pumps with rotating vanes. Characterized by newly conceived ejectors, these exclusive pumps have an extraordinary ratio between the quantity of compressed air used and the sucked (or generated) air, a big advantage for the operational consumption. Furthermore they have the ability to adjust the vacuum level (or pressure level) and the capacity, based on the pressure of the supply air. Moreover the choice of high tech materials of the latest generation, reduces their weight, thus allowing the installation directly on the machine. Vuototecnica s research centre turned its highest attention to the reduced noise of these new pumps, thanks to solutions that provide a full soundproofing with no moving components, thus improving life and avoiding troublesome vibrations. In addition they are based on the Venturi principle that exploits the kinetic energy of the compressed air by means of ejectors in line and consequently they do not develop any heat. The excellent filtering of the compressed air supply and of the sucked air provides oil free blow air as well as being free of oil vapours, water condensate and impurities for the sheet separation on the machine and the working environment with regard to air pollution. Maintenance being reduced to only periodic filter cleaning and an incomparable reliability complete the range of advantages of this safe and competitive technology. These pneumatic suction and blowing pumps are shown and described on the following pages. SPECIAL VACUUM CYLINDERS By assembling a cup on a hollow stem and creating a vacuum, the cup will be quickly brought into contact with the sheet or the object to be taken, will automatically lift it and will keep it as long as the vacuum supply remains. Thanks to this feature, cylinders of this series, used in connection with the cups, are recommended for the separation of paper or plastic sheets. They offer the following advantages: high speed in operation, automatic compensation of the height of the objects to be taken, non-rotating stems, extremely simple fixing. These special cylinders for vacuum are shown and described on the following pages. CUPS Made in the most varied shapes and dimensions, to assure a quick and safe grip, they can be supplied in an anti abrasive natural para rubber, in nitrile rubber, in silicone, in Viton, in polyurethane and in other compounds too, according to the specific requirements. Cups are shown and described in detail in chapter 1; in this chapter only disc cups are shown

14 [Holding supports for pneumatic suction and blowing pumps] The holding supports shown on this page have been designed to allow a quick assembly of the pneumatic suction and blowing pumps and to easily position them on the machine to be interlocked. They are made with a strong stainless steel plate and are provided with non-slip vibration-damping rubber feet. These holding supports are currently available for both single and combined pneumatic pumps. Art. A B C D E F G H I L M N O P Q Ø Ø GR DIV GR DIV

15 [Suction filters for pneumatic suction and blowing pumps] These filters have been developed in order to permit pneumatic suction and blowing pumps working also in very dusty environments. When installed on their suction connections, they are able to stop very thin powders, interfering on the flow capacity in an almost negligible way. Actually, the filtering element is made with special treated paper, with a porosity degree of 5 7 micron, pleated to increase the filtering surface. The FP filter bowl is made of a transparent plastic and it is screwed to the head, also made of plastic; a gasket placed between the two elements, assures a perfect seal. The head and bowl of the FC filter are manufactured from steel plate with a special painted surface to prevent oxidization. A gasket placed between the head and bowl assures a perfect vacuum seal and the release clamps, placed on the bowl, allow a quick opening of the head to check or replace the filtering element.

Making vacuum in the cylinder s front chamber, the stem, integral to the piston, comes out, thus overcoming the opposing spring force. The piston is pushed by the air at atmospheric pressure that gets into the cylinder s rear chamber, through the hollow stem. The larger the pressure differential that is developed between the cylinder front chamber under vacuum and the rear chamber at atmospheric pressure, the larger the piston thrust force. The stem can operate in two ways: 1 st Preventing the inlet of atmospheric air through the hole of the stem and with the vacuum connected, the pressure differential in the cylinder is eliminated; in this condition the forces of the opposing spring and of the atmospheric pressure will prevail on the stem itself, consequently it is pushed in its initial position. 2 nd By cutting out vacuum, the atmospheric pressure in both cylinder chambers is restored; also in this case, as there is no more pressure differential, the stems returns in its initial position, pushed by the opposing spring only. The first way described above is the real operating principle for which the cylinder has been designed. Actually, by assembling a cup on the cylinder s hollow stem and making vacuum, the cup will be quickly brought in contact with the object to be taken, will automatically lift it and will keep it as long as vacuum is connected. Thanks to this feature, special vacuum cylinders, combined with the cups, are especially recommended for taking and handling small machined, moulded or thermoformed objects, to separate paper, plastic, or thin plate sheets, etc. and to pick up printed circuits or thin plastic panels. Short and quick cycles, operated by only one vacuum interception valve, automatic compensation of the height of the objects to be taken and no compression on them, non-rotating piston, very simple fixing: these are the real advantages offered by the special vacuum cylinders. Made entirely of anodized aluminium, they are provided with a special self-lubricating bush that assures their long life.

17 [Disc cups] With the exception of some standard rubber discs, these parts are generally produced on customer s specifications and for minimum quantities specified in our offers. They can be punched by sheets, or moulded, in nitrile rubber, in natural para rubber, in silicone rubber or in special compounds; they can also be manufactured in linen-faced rubbers or polyurethanes. The above described discs are used in the printing industry, as an alternative to cups, for handing and moving paper,cardboard and plastic sheets. Art. D d S Ø Ø
