PIAB "piSAVE sense" vacuum check valve

The piGRIP® FLC is a new interface component that is compatible with all existing Piab suction cups. Regardless of the application, it allows for easier and more sophisticated adjustments for height differences and angles during picking. By adding the FLC between the piGRIP bellows and your preferred suction cup, the flexibility of operation is significantly enhanced. It enables the use of cups that were previously unusable due to insufficient stroke, while maintaining unique sealing performance and friction patterns. The FLC interface features a joint function that expands the range of motion by adjusting the angle of the suction cup relative to the workpiece. Additionally, by using a clamp fitting, the FLC, bellows, and suction cup can be securely fixed, reducing the risk of the cup detaching during operation. This also significantly lowers the risk of damage to the workpiece during transport. Furthermore, by incorporating the piSAVE sense valve between the piGRIP FLC and the suction cup, it becomes possible to control the extension and contraction of the FLC stroke before picking.

In cases where all suction cups do not make contact with the workpiece, vacuum leakage occurs, requiring a larger ejector than normally necessary. By using piSAVE sense, when the suction cups do not contact the workpiece, the valve of piSAVE sense closes, minimizing vacuum leakage. Only the valves of the suction cups that are in contact with the workpiece open, allowing for suction.
