Abstract
The purpose of this study is to experimentally evaluate the performance of two models of new type of contact pneumatic grippers. One of them is two-dimensional and the other one is axisymmetric, which uses a dual throat ejector to handle limp and porous materials. In two-dimensional device, slotted plates with different slot width was used to investigate the effect of slot width and total pressure of inlet flow on the performance of the gripper. In the axisymmetric gripper, perforated rings with different hole diameters was used to evaluate their effect and the effect of high pressure inlet flow on the performance of the device. Results show that in both grippers, by increasing inlet pressure, the induced pressure and suction force to hold limp materials increases. Also, regardless of the gripper mass flow rate consumption, the axisymmetric gripper with higher mass flow consumption creates more force and suction pressure, but the performance of the two-dimensional gripper in producing suction force is much better by considering the mass flow rate consumption.
