1. An apparatus for automatically recovering meat from headed and gutted fish, the apparatus comprising:
a transport device for transporting the fish along a transport path in a transport direction T;
a measuring device for detecting an anatomy of the fish;
a single circular knife drive unit;
a control unit electrically connected to the measuring device; and
a detaching device for detaching the meat from a bone structure of the fish, wherein the detaching device comprises at least two rotatingly driven and controllably moveable circular knives which are spaced apart from each other on mutually opposing sides of the transport path to form a gap S, the at least two circular knives driven by the single circular knife drive unit;
wherein:
the detaching device comprises a control device set up to adjust a width of the gap S depending on a height, length and/or width of the fish detected by the measuring device;
the control device is configured to pre-adjust the width of the gap S before the meat is detached from the bone structure and wherein the control device is configured to vary the width of the gap S while the meat is being detached from the bone structure;
the control device comprises a cam control, the cam control comprises a cam disc driven by a control drive unit for changing the position of the circular knives; and
the control unit actuates the control drive unit in such a manner as to adjust the circulation of the cam disc in a predetermined angular velocity profile.
