Abstract
A gripper for grasping and handling textiles and other flexible materials includes an external body housing a driving unit, which actuates a plurality of sliding elements moving away and approaching symmetrically; and a plurality of gripping members, each connected to one of the sliding elements by a first transmission group that includes a kinematic chain with levers that invert motion such that, during the approaching of the sliding elements, the gripping members move away from each other, and during the distancing of the sliding elements, the gripping members approach each other.
Claims12
A gripper comprising:
- an external body (1);
- at least one driving unit housed within the external body, said driving unit actuating at least two sliding elements (11) according to a translational movement, such that said sliding elements (11) move away from and approach each other symmetrically with respect to a longitudinal mid-plane (A) of the gripper, passing from a maximum mutual approach condition to a maximum mutual spacing condition;
- and
- at least two gripping members (21, 22) each connected to one of the sliding elements (11),
- wherein each of the gripping members (21, 22) is connected to one corresponding sliding element (11) through a first transmission group causing a translation movement from the sliding elements (11) to the gripping members (21, 22), and
- wherein the first transmission group comprises a kinematic chain (31, 32, 33 e 34) having levers that invert motion, such that, during the approaching condition of the sliding elements (11), the gripping members (21, 22) move away from each other and, during the spacing condition of the sliding elements (11), the gripping members (21, 22) approach each other, being the mutual spacing and approaching of the gripping members (21, 22) performed with respect to the longitudinal mid-plane (A).
