The suspensions (or buffers, or level compensators) are used to keep the suction cups in position as the robot approaches. Gimatic offers a range specifically designed for Plastics applications. They are typically mounted on EOATs (End Of Arm Toolings) with MFI brackets.
The reaction force depends on the compression (S) of the internal spring. And also on the piston diameter (d) and operation pressure (p), in the case of telescopic suspensions. Use the following formula for calculation. Reaction force Spring force at the beginning Spring rate Compression stroke Piston bore Pressure Spring force at the end-stroke Maximum stroke Weight R [N] R1 [N] K [N/mm] S [mm] d [mm] p [bar] R2 [N] S2 [mm] m [g]
