Gripper, conveyor system, and method for operating such a conveyor system

摘要

A gripper for grasping and conveying objects while retaining the objects, and to a corresponding conveyor system and an operating method. The gripper has a gripper body and first and second gripper jaws. The gripper jaws each include at least one respective clamping region, can assume an open state and a closed state relative to each other, and can exert a clamping force on each other or on the object to be grasped. At least one of the gripper jaws includes a jaw body that is elastically deformable and is supported on the gripper body such that the body assumes a defined spatial position (resting position) when force is not applied to a control element and deforms and is deflected from the resting position when force is applied to the control element.

1. A gripper for grasping and conveying spatially extended, symmetrical objects, said gripper having a gripper body, a first gripper jaw and a second gripper jaw, each of said first and second gripper jaws comprising at least one clamping region and being able to assume an open and a closed state in relation to one another and being able to exert a clamping force onto the object to be grasped, and said gripper having at least one control element that is adapted to interact with a control link so as to move said first and second gripper jaws between the open and closed states, said at least one control element being part of the gripper and being moved together with the gripper in a conveying direction whereas the control link is stationary and positioned so that the at least one control element is moved into engagement with the control link, and applies a force to the at least one control element, as the gripper and the at least one control element are moved in the conveying direction, wherein at least one of the gripper jaws includes a jaw body that is elastically deformable and is mounted on the gripper body such that, when the control element is out of engagement with the control link, the gripper jaws assume a defined spatial position and, when the control element is in engagement with the control link, the gripper jaws deform and are thereby deflected out of the defined spatial position.
