Pneumax-Technology for vacuum applications

Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice. VII Choice of suction cup: Pneumax suction cups are available in different shapes, each one of which can meet a number of existing application requirements; the choice of cupmust bemade based on the characteristics listed below: Suction cup Flat series TP: Suction cup to be used for moving sheets and in those applications where the lifting force is parallel to the gripping plane. Internal reinforcements improve stability andmake this cup suitable for handling heavy objects. Suction cup Bellows series TS: Suction cup best used in particular for moving light items in those applications where the lifting force is vertical to the gripping plane. The range of the bellows makes it possible to compensate for the irregularity of the surface and height of the object. The long bellows suction cup is best used in applications where it is necessary to pick off and move light products such as: leaves of paper or pieces of cardboard, thin sheets, wood panels, etc. Due to their greater flexibility, these can be used to compensate for errors of flatness or to grip inclined surfaces, but are not suitable for applications with parallel loads or with a high degree of vacuum. Suction cup (Plain) Cup series TN: Among themost common types of suction cup, used in sectors of industry where special performance is not required: Handling of objectsmade of plastic, wood panels, thin sheets of glass andmetal, etc. Recommended for vertical movement of heavy objects. HighGrip suction cup: Suction cup with high coefficient of friction, developed for the handling of oily surfaces, such as sheet metal in moulding processes, and also recommended for handling wet marbles and glasses, slabs and loads in general, subject to high accelerations and decelerations duringmovement. Recommended for the "automotive" sector, available in various sizes and shapes: round and oval flat and round and oval bellows. Suitable for horizontal and vertical movement. Foam rubber suction cups: This suction cup allows for the moving and gripping of loads with coarse, very rough or uneven surfaces, such as: textured, non- slip or ribbed/corrugated sheets, and sawn, bush-hammered or flamed marble. Items made of rough concrete, garden walkway tiles and brick in general. Recommended for use with oiled surfaces and tomove vertical loads. Choice of Mix. The choice of mix to be used is made by consulting the technical tables as a function of the individual application, and after having carefully evaluated the following factors : E Surface roughness of the load to bemoved and its temperature E Weight and dimensions of the load. E The presence of chemical substances, oils, solvents etc. on the gripping surface. E How labour-intensive and complex the work processes are. E How important it is to ensure that no specks exist on the gripping surface. Suction Cup Characteristics and Materials Level Compensator: This accessory makes it possible to overcome differences in height that may be found in various applications, for example in lifting systems where the suction cups are fixed to a rigid structure or when a suction cup is used on the armof an anthropomorphic robot or in a similar system where the items must be accurately positioned at the required height; in addition, the device makes it possible, within certain limits, to absorb pushback. The Pneumax range is subdivided into three types: l Compensator with external spring l Compensator with internal spring l Anti-rotation compensator with internal spring Series 1900 Material N-NBR S-Silicone PU-Polyurethane F-Fluorinated rubber Temperature °C -20 ÷ +110 -40 ÷ +200 10 ÷ 50 -10 ÷ +230 Abrasion resistance Excellent Good Excellent Excellent Oil resistance Excellent Low Excellent Very good Resistance to weather/atmospheric agents Very good Excellent Excellent Very good Vacuum components Vacuum technology
