Graphic division – product description

The experience and production capacity of Vuototecnica has originated a division specially dedicated to the graphics and printing sector. A reference entity, ranging from engineering to services, that offers innovative and advantageous technical solutions under every point of view: performance, reliability, duration and operational economy. A significant demonstration of the Graphic Division specialisation is represented by the new range of products among which:

PNEUMATIC SUCTION AND BLOWING PUMPS
These state of the art multi-ejector (multi-stage) pumps are very versatile and can either suck or blow, according to the requirements, thus representing a true evolution compared to the traditional rotating vane pumps. These pumps feature state of the art ejectors and boast an exceptional ratio between the amount of consumed air and sucked (or generated) air, all to the benefit of operational consumption. Moreover, they adjust the vacuum (or pressure) level and capacity according to the air supply pressure. The state of the art hi-tech materials have considerably reduced the weight allowing them to be installed directly on the machine. The Vuototecnica research centre has focused its attention on noise reduction, with solutions that provide for full soundproofing and no moving parts, thus prolonging duration and eliminating any vibration. Furthermore, these pumps are based on the Venturi principle which exploits the compressed air kinetic energy via in-line ejectors and, therefore, do not develop heat. The excellent compressed air and sucked filtration allows blowing air free from oil vapours, water condensation and impurities, between the sheets of paper to be separated and in the work environment, causing no pollution. Other assets of this safe and competitive technology include a minimal maintenance, limited to a regular filter cleaning operation, and reliability with no comparison. The pneumatic suction and blowing pumps are described in the following pages.

VACUUM CYLINDERS
By assembling a vacuum cup onto their perforated stem and creating a vacuum, the cup will quickly come into contact with the sheet or the object to be handled and it will automatically lift it, holding it until the vacuum is excluded. For all these features, this range of cylinders combined with cups are particularly recommended for separating sheets of paper or plastic. The advantages include: high speed operation, automatic compensation of the height of the objects to be lifted, non-rotating stems and extremely easy fixing. These vacuum cylinders are described in the following pages.

CUPS
They come in a large variety of shapes and sizes, to guarantee a quick and safe grip and they can be provided in anti-abrasion natural para rubber, nitrile or oil-resistant rubber, silicon, Viton, polyurethane and other compounds, according to the requirements. Vacuum cups are described in detail in Chapter 1; this chapter, however, will focus on the disc cups only.

Suction and blowing system AS

Suction and blowing system AS

With the suction and blowing system AS we have tried to provide the printing industry with an answer to most of their requirements regarding the management of paper during the printing process, i.e.:
- The concentration of all the necessary pumps and commands on one single piece.
- An increased printing quality thanks to individually controlled pumps.
- An increase of productivity resulting from the configuration and use of individual pumps.
- Reduced machine idle state due to the pneumatic pumps based on the Venturi principle.
- An improvement of the work environment thanks to the noise reduction, absence of heat and the emission of air free of oil vapours, water condensation and impurities between the sheets of paper to be separated and in the work environment.
- Energy saving due to a low compressed air consumption compared to the amount of sucked (or generated) air.
- Maintenance reduced to a regular cleaning of the filters.
The suction and blowing system AS is composed of a metal, easy-to-place cabinet, inside of which the combined pneumatic pumps PA and PS are located with the supply compressed air interception and adjustment valves. The suction and blowing capacities of the pumps are determined according to the client’s requirements or to technical specifications of the machine manufacturer. At the sides of the cabinet are located the blowing and suction connectors for the connection to the application, as well as the filters equipped with micro-porous cartridge against fine dust. On the control panel are installed:
- The pneumatic main switch for supply compressed air interception with a pressure gauge for a direct reading of the line pressure.
- The pneumatic switches for supply compressed air interception of every single pump.
- The pressure reducers with relative pressure gauges for adjusting the compressed air of every single pump. The vacuum (or pressure) level as well as the pump capacity can be adjusted according to the supply air pressure.
- Vacuum gauges and pressure gauges for a direct reading of the vacuum and pressure at the application.
- Vacuum gauges for controlling the clogging level of the PS pump filters. All our pneumatic suction and blowing pumps can be combined regardless of their suction and blowing capacity and can be installed inside the system cabinet. Given the enormous number of possible combinations, this catalogue only describes combinations of pumps with the same size.

Pneumatic pump suction filters

Pneumatic pump suction filters

To allow the pneumatic suction and blowing pumps to work even in very dusty environments it is necessary to use these filters that, installed on the suction inlet connection, can keep the finest dust and impurities and affecting the capacity in a negligible manner.
The filtering cartridges, in fact, are made with a special treated paper with a porosity level of 5 ÷ 7 micron, and pleated to increase the filtering surface. FCL filters are composed of a transparent plexiglas cylindrical body inside of which is located the filtering cartridge locked by two anodised aluminium flanges that are kept in place by Seeger rings, inside of which the threaded connectors and the seals are housed.
The filters can be inspected by simply removing one of the two flanges. The container of the filtering element FP is made with plastic and it is screwed onto the blue plastic lid; a gasket located between the two elements ensures a perfect seal. The container of the filtering element FC, as well as its lid, are made with sheet steel and varnished with a special oxidation-resistant treatment. A gasket between the lid and the container ensures a perfect vacuum seal, while the release clamps on the container allow a quick opening of the lid to check or replace the filtering cartridge.

Vacuum cylinders

Vacuum cylinders

The cylinders described in this page are vacuum operated. By creating vacuum in the cylinder front chamber, the stem, which is solidly connected to the piston, comes out 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 greater the pressure differential between the front chamber under vacuum and the rear chamber at atmospheric pressure, and the larger the piston thrust force will be. The stem returns into position in two ways:
1) By preventing the atmospheric air from entering through the stem hole and with the vacuum inserted, the pressure differential inside the cylinder is removed. Under this condition, the thrust spring and the atmospheric pressure forces prevail on the stem which is thus pushed into its initial position.
2) By excluding the vacuum, the atmospheric pressure is restored in both the cylinder chambers. Also in this case, being the pressure differential removed, the stem returns to its initial position pushed by the thrust spring. The first of these two methods is the true operating principle for which this cylinder has been designed. In fact, by assembling a vacuum cup on the cylinder hollow stem and creating a vacuum, the cup will rapidly come into contact with the object to be handled and it will automatically lift it keeping the grip until the vacuum is excluded.
For this feature, vacuum cylinders associated with vacuum cups are recommended for gripping and handling machined, moulded or thermoformed objects, as well as for separating sheets of paper or plastic, sheet steel, etc. and lifting printed circuits or thin plastic panels.
The advantages offered by these vacuum cylinders include: brief and quick cycles controlled by only one valve for vacuum interception; automatic compensation of the height of the objects to be gripped with no compression on them; non-rotating piston and an extremely easy fixing. They are fully made with anodised aluminium and are equipped with a special self-lubricating technopolymer bush which guarantees long duration.
