486 Nine VACUUM GRIPPER SYSTEM – VGS™ & ENERGY SAVERS ENABLES EASY SELECTION AND ACCURATE DIMENSIONING Piab’s decentralised vacuum gripper system, VGS, is a product solution, integrating high quality suction cups with COAX cartridges. • VGS makes selection, sizing and installation of a vacuum system much easier. Design and dimension errors will be avoided. • You will enjoy the benefits of a more efficient and reliable vacuum system. • Increased machine speeds can be achieved, thanks to faster response times, with the vacuum source right at the cup and better initial vacuum flow, which will grip the object faster. • The decentralised approach provides safety with one vacuum source per suction point. It also eliminates flow losses in long vacuum hoses, making maximum use of energy. • VGS 3040 with integrated energy saving functions, like Vacustat and AQR02 (Atmospheric Quik Release) is a pioneering product and the world’s most energy efficient concept for vacuum handling of sealed parts, such as glass and metal sheets. piSAVE optimise • Vacuum controlled proportional pressure regulator, a fully pneumatic device suitable for air driven ejectors / pumps. • The feed pressure to the vacuum pump / ejector is automatically regulated and controlled to maintain the set vacuum level. Air / energy usage is kept to a minimum for the application (optimised). • Recommended for leaking and sealed applications to save energy and secure the right vacuum level. • Extra port for vacuum gauge. • Air ventilation port with filter. • Swivel compressed air connections. • piSAVE optimise gives maximum feed pressure / flow to vacuum pump / ejector until vacuum level starts to build up. • Separate mounting bracket kit. • Upgrade kit – available as an integrated module for piCLASSIC and Classic vacuum pumps. piSAVE on/off • Independent pneumatic air-saving device for vacuum pumps. • Adjustable vacuum controlled 2/2 NO valve. • Available with large hysteresis for object handling and small hysteresis for process applications. • The Vacustat is recommended for vacuum pumps in non-leaking systems. • The vacuum pump must be fitted with a non-return valve. piSAVE release • Equalises pressure in the suction cups to provide fast release of the product. • Extra fast release by accumulating and utilising the feed air pressure as a boost. • ON / OFF activated simultaneously with the ejector. • No additional controls required – use a single 3/2 control valve for the ejector and piSAVE release. piSAVE sense • Vacuum check valves, which allow a few suction cups to miss the object(s) and still maintain enough vacuum level in the system with quick response and release times. • The vacuum check valves shall be used in a centralised vacuum system, one for each suction cup. • Designing with vacuum check valves will require a smaller vacuum pump and save energy. • Suitable for handling different sized or a different number of leaking objects, such as MDF boards, corrugated cardboards, with a flexible handling device. • Also suitable for objects with surface leakage around the lip of the suction cup. • Available in three sizes with different flow performance / characteristics to suit different degrees of leakage. • The valves are integrated in an AI-fitting with female and male threaded connections to facilitate installation.
