Abstract
A gripper having at least two gripper arms movably arranged in a pincer-like manner on a base part and a cutting device for material to be cut for attachment to a processing machine, wherein the cutting device is formed by a cutting plate, which is movable by a piston-cylinder unit from an active position, in which the cutting plate projects into a receiving space for the material to be cut enclosed by the gripper arms, into an inactive position, in which the cutting plate is retracted in the base part. The retractable and extendable piston rod of the piston-cylinder unit is connected to the cutting plate via a driver pin which, in the active position of the cutting plate, rests against an abutment of the base part when the cutting plate is loaded.
Claims9
A gripper comprising:
- at least two gripper arms arranged in a pincer-like manner on a base part so as to be movable relative to one another;
- and
- a cutting device for material to be cut for attachment to a processing machine is formed by a cutting plate which is movable with the aid of a piston-cylinder unit from an active position, in which the cutting plate projects into a receiving space for a material to be cut enclosed by the at least two gripper arms, into an inactive position, in which the cutting plate is retracted in the base part,
- wherein the cutting plate is pivotably mounted on the base part about a first pivot axis perpendicular to the cutting plate, and a cylinder of the piston-cylinder unit is pivotably mounted on the base part about a second pivot axis parallel to the first pivot axis,
- wherein a retractable and extendable piston rod of the piston-cylinder unit is connected to the cutting plate via a driver pin which, in the active position of the cutting plate, rests against an abutment of the base part when the cutting plate is loaded,
- wherein the driver pin is guided via ball bearings in a link guide of the base part, a clear cross-section of which widens in a region of the abutment to ensure a spacing of the ball bearings from a leading cam track of the link guide when the driver pin rests against the abutment.
