ZERO-G is an exclusively pneumatic manipulator for handling flat glazing and windows in absolute safety. By means of the load gripping equipment the spatial positioning of the object handled can be monitored constantly across an extensive working area. Its ergonomic design allows for tilt and rotation movements that ensure high speed and flexibility throughout the entire work process. The suction cup gripping system in conjunction with the weight balancing system enable movements to be made along two axes throughout a working area having a radius of up to 6000 mm. The configuration on a free-standing base allows maximum freedom of movement within the production facility.
The balancing system, by means of a thrust device mounted on recirculating ball bearings and linear guides, ensures perfect compensation of the vertical load in any position and along the entire stroke. Zeroing of the product weight is done by means of a preselector that is adjusted manually, or by the push-button lever balancing system (optional). The movement system is extremely smooth and fluid and, once the weight of the object is balanced, requires no effort on the part of the operator. The manipulators are equipped with parking brakes on all three axes. Once the operator has applied the brakes by acting on the appropriate control on the console, the machine remains in the position reached.
Product gripping is quick and easy thanks to suction cups controlled by an extremely efficient vacuum system. ZERO-G can handle different product geometries by adjusting the position of the suction cup system. The release operation always takes place under the safest conditions thanks to a special device that accompanies the product in support before allowing its complete release, thus avoiding possible accidents due to incorrect or accidental manoeuvres.
ZERO-G allows the operator both 90° pneumatic tilting and 90° pneumatic rotation of the product independently of each other. Both functions are controlled directly from the console and are proportional in nature, thus also allowing grasping from trestles or inclined stands. In addition to the individual suction cup adjustments, for the ZERO-G 250 model there is the option to exclude, via a selector switch on the console, two of the four gripping suction cups, thus allowing the gripping of long and narrow products. To ensure safe load lifting at all times, the machine is equipped with an automatic capacity reduction system that is activated when the two suction cups are excluded, so that the operator is prevented from lifting excessive loads. An accumulation system allows you to benefit from an air reserve with which you can safely terminate load supporting operations, even in the event of a sudden lack of supply system pressure.
The unique console is ergonomic and practical in use; with controls arranged in a simple and intuitive manner, the operator feels at ease from the very first movements and is able to take full advantage of Zero-G’s potential, safely guiding the product in any direction with minimal effort. The console can slide along the handle to better adapt to situations dictated by the work cycle, allowing the operator to choose the most comfortable position while respecting work ergonomics. On the console there are controls for load gripping and release, weight reset adjustment, pneumatic tilt and rotation functions in addition to the brake selector switch.
