Suction gripper for food

A suction gripper for use as lifting device for an object, wherein the suction gripper has a suction opening opened up by a pipe section forming a suction section, wherein at a distance to the suction opening a convex surface is arranged spaced from the suction section by an annular outlet, which convex surface opens up a first opening of a central channel formed within a central well, wherein the convex surface leads into an axial section having the smallest cross-section of the central channel to which a section of the central channel adjoins that broadens towards a second opening opposite the first opening, and the annular outlet is connected to a compressed-air connection by an inlet duct, wherein the central well is guided longitudinally displaceable in a recess of the pipe section, until a first abutment face of the outer surface of the central well opposite the central channel lies against a parallel second abutment face of the pipe section, wherein the central well is guided in a recess of a socket of the pipe section, and the second abutment face comprises the recess of the socket.
