Abstract: The apparatus for cutting shells of eggs with laser beams (2) of a laser (1) for opening the eggs, comprises a transport device (4) for a carrier (5) with eggs standingly arranged in a plane, where the transport device is a first component of a frame (3), an optical system (7) for conducting laser beams, and laser beam focusing devices coupled as mechanisms to a drive system acting in x-direction and y-direction, so that the eggs are movable by the transport device, the optical system and the focusing devices corresponding to each other. The apparatus for cutting shells of eggs with laser beams (2) of a laser (1) for opening the eggs, comprises a transport device (4) for a carrier (5) with eggs standingly arranged in a plane, where the transport device is a first component of a frame (3), an optical system (7) for conducting laser beams, and laser beam focusing devices coupled as mechanisms to a drive system acting in x-direction and y-direction, so that the eggs are movable by the transport device, the optical system and the focusing devices corresponding to each other and the shells of the eggs are successively or groupwisely cut by the focused laser beams moved in x-direction and y-direction of the drive system. The mechanism is arranged in a closed chamber as a second component of the frame. An area of the second component consists of a material transparent for the laser beams for the passage of the laser beams to cut the shells of the eggs. The laser, the transport device and the component of the mechanism are switched together with a control device. Sensors are present for detecting the presence of the eggs over the transport device, are connected with the control device and are spacer sensors or light barriers. The laser beam focusing devices are arranged in a row, so that a beam dump and a folding mirror or a processable mirror in the beam path above the focusing device are arranged, so that the laser beams strike on the shell of the egg during the presence of the egg or on the beam dump during the absence of the egg, where the drives for the folding mirror or processable mirror are connected are connected with the control device. A first beam splitter is arranged in the beam path below a device coupling the laser beams. A second beam splitter and a deflection mirror are present in the beam path below the first beam splitter for the first and second partial beams. The folding mirror or processable mirror and the focusing device are arranged below the second beam splitter and the deflection mirror. The device consisting of the second beam splitter or folding mirror or processable mirror and the focusing device are processably arranged at the mechanism, so that the distance is adjustable to an adjacent device. The device consisting of the deflection mirror or second beam splitter or folding mirror or processable mirror and the focusing device are processably arranged at the mechanism, so that the distance is adjustable to an adjacent device. The carrier is a plate with openings or recesses arranged in several rows for partial reception of the egg, where a row is arranged transverse to the transport device of the plate. The laser, the transport device and the component of the mechanism are switched together with the control device, so that the shells of rows of eggs are cut.
