Coupling system for a gripper attached to a robot

A coupling system for a gripper which is attached to a robot and which comprises a robot-side flange and a gripper-side flange, wherein in the robot-side flange, a first line is formed, and in the gripper-side flange a second line is formed in order to convey a medium, wherein the robot-side flange is coupled to the gripper-side flange in a form-fitting manner so as to be secured against twisting such that the first line and the second line are in alignment in order to establish a fluidic connection with each other,

• wherein the gripper-side has a through bore that is open on one side, the through bore has a through bore diameter and an insertion opening with an opening width, the through bore diameter is greater than the opening width,
• wherein a locking between the robot-side flange and the gripper-side flange is realized by a locking bolt arranged moveably on or in the robot-side flange, the locking bolt has a first bolt diameter and a second bolt diameter, the first bolt diameter is greater than the second bolt diameter, and
• wherein the first bolt diameter is greater than the opening width.
