Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice 8 Suction cups Suction cups are vacuum accessories that are indispensable whenever it is needed to lifting, clamping or handling manufactured products, sheets or other objects that are “difficult to grip” with traditional gripping means, because they lack handholds, are fragile or are easily deformable. Correct application of suction cups ensures simple, economical and safe gripping operations, which are critical requirements for the proper execution of any automatic action. The suction cup adheres to the surface of an object whenever the pressure surrounding it outside (atmospheric pressure) is higher than the pressure existing between the suction cup and the surface of the object. In order to generate low pressure inside the suction cup, the latter may be connected to a vacuum pump. The lifting force of the suction cup will depend on the degree of vacuum attained by the pump and its capacity to compensate for losses. The suction cup is an effective, simple and economical system for handling all kinds of shapes and surfaces. The suction cup itself can have a number of different shapes: Conversion table for positive pressure Conversion table for negative pressure Conversion table of Flow rate per unit of time flat, oval, conical bellows with the possibility of adding various accessories, such as filters, shut-off valves, level compensators. Any given suction cup is designed for a specific vacuum movement application. Applications: Gripping, handling, lifting, forming, palletising, pick & place, transferring, positioning. Thematerials that can bemanaged with suction cups are highly varied, but we can roughly categorise them as follows: METALS: heavy loads, large sizes, middle frequencies, dirty surfaces. PLASTIC: light loads, medium to small sizes with irregular shapes, no surface deposits. WOOD: rough surface, slightly deformed, middle-weight loads, no surface deposits.
