A few months ago we presented Vuototecnica Graphic division on the blog, entirely designed to meet printing and graphic industry’s needs. More than just offer its customers products, Vuototecnica as usual supports customers from engineering to customer service. Today we see three products.
The printing industry requires – in addition to excellent performance – speed, instruments reliability to avoid costly stops, longer component life and affordability.
The Graphic division range was developed to meet these requirements and consists of different size and capacity PA suction and PS blowing pumps, PA and PS pumps combined together, every shape and material suction cups, filters, spare parts and holders for every application.
Within this product range we mention:
AS suction and blower system designed for the management of paper during the printing process. It is a cabinet and it is compact and simple to use. It contains suction and blowing pumps combined together inside, compressed air control and shutting off valves and all the controls. Blowing and suction connections for use and microporous cartridge filters are placed on the sides of this metal cabinet. They are capable of retaining even the finest dust which is usually found in printing environment. On the control panel, there are: the general pneumatic switch for intercepting supply compressed air, together with a pressure gauge for line pressure direct readout; pneumatic switches for intercepting the supply compressed air of each pump; pressure reducers with pressure gauges on, to adjust the compressed air of each pump; precision vacuum gauges and pressure gauges to read out directly the vacuum and pressure degrees; vacuum gauges that allow you to control the degree of blowing pumps filter clogging. The pumps can be controlled individually, and this allows high quality and a strong increase in productivity. The pneumatic pumps are based on the Venturi principle, this prevents downtime. Depending on the supply air pressure, it is possible to adjust the vacuum degree (or the pressure degree) and the pumps flow rate. The three visible benefits of this system are: high compressed air energy saving, a maintenance reduced to periodic filter cleaning, a healthier and less noisy work environment (no emission of oil or condense), no impurities on paper sheets to be separated.
Vacuum cylinders are very suitable for the separation of paper or plastic sheets in combination with suction cups. They work in depression on short and fast cycles. They have a hollow rod on which you can assemble the suction cup and they are made of anodized aluminum for extra durability. The operation is simple: we create the vacuum in the anterior chamber of the cylinder, so the rod, integral with the piston, comes out and wins the opposing force of the spring. The piston is pushed by the air at atmospheric pressure which enters the rear chamber of the cylinder, through the hollow rod. The greater the pressure differential between the anterior chamber of the vacuum cylinder and the rear chamber at atmospheric pressure, the greater the thrust force of the piston. The rod part when you disallow the entrance of atmospheric air through the hole of the rod and with the vacuum inserted you delete the pressure differential in the cylinder because the forces of the opposing spring prevail and the rod returns to its initial position, in this way. Even in the event that the vacuum is excluded, and you restore the atmospheric pressure in both chambers of the vacuum cylinder, the pressure differential is reset and the rod returns to its initial position. These cylinders are very fast, able to compensate for the height automatically. The rod is non-rotating and it is very simple to mount them.
The disc cups guarantee a quick and safe grip and are produced depending on the specific needs of the customer, based on the material to be manipulated (paper, cardboard, plastic). They can be die-cut from sheets, printed in oil resistant or nitrile rubber, in natural para rubber, or abrasion resistant rubber, in silicon, Viton, or other special compounds; they can be made in rubber or polyurethane panels and in any material is required by the end user.
