The locking element is preferably intended to cause, limit and/or block a movement of the coupling elements, in particular along at least one longitudinal axis of the coupling elements, relative to one another by means of a positive and/or non-positive connection with at least one of the coupling elements. For example, it is conceivable that the locking element engages in a locking recess of the locking unit, which is arranged on one of the coupling elements, in particular is formed in one piece with one of the coupling elements, that the locking element is designed as a magnet, in particular as an electromagnet, and for exerting a magnetic force is provided on at least one of the coupling elements, or that the locking element has another configuration that appears sensible to a person skilled in the art in order to cause, limit and/or block a movement of the coupling elements relative to one another. “Provided” is intended to mean, in particular, specially set up, specially designed and/or specially equipped.

If the size of an actuating force acting on the actuating element falls below a limit value, for example, there can be no rotationally fixed connection between the actuating element and the fixing element, but rather, for example, the actuating element continues to be movable relative to the fixing element. It is alternatively or additionally conceivable that a rotationally fixed connection between the actuating element and the fixing element by means of the coupling element is dependent on a length of a movement path of the actuating element relative to the fixing element. By means of the design according to the invention, a secure fixation of a functional carrier on the transport device, in particular on the carrier element, can be realized in a structurally simple manner. Preferably, an actuation of two different fixations or movement locks can be made possible by means of a single actuating element. A simple, easy-to-operate quick-change function of the transport device, in particular of the transport track, and/or of the function carrier of the carrier element can be made possible in a structurally simple manner. A high level of operational reliability can advantageously be achieved. It can advantageously be made possible to securely hold the coupling elements in a position relative to one another in order to counteract the transport device being loosened by operating forces.

The conveyor or production machine can include further devices and/or units that appear useful to a person skilled in the art and that can be used for the production, transport and/or handling of products, in particular food. By means of the embodiment according to the invention, a high level of operational reliability can advantageously be achieved, in particular with regard to operational security against unintentional detachment of the transport device from the transport path in the event of high driving dynamics as a result of an unwanted relative movement of the coupling elements. It can advantageously be made possible to securely hold the coupling elements in a position relative to one another in order to counteract the transport device being loosened by operating forces. It can be advantageous to move in a structurally simple manner the coupling elements in a securing position and holding the coupling elements in the securing position can be realized.

The fixing element 58 is preferably connected to the function carrier 56 in a positive and/or non-positive manner, in particular as a result of an engagement in the fixing recess 60. The fixing element 58 is preferably hook-shaped, in particular as a locking hook or as a hook-shaped extension or the like. The fixing element 58 can preferably be inserted into the fixing recess 60 in a state of the functional carrier 56 arranged at the receiving interface 54 by a movement of the actuating element 42, in particular by a pivoting movement of the actuating element 42 about the actuating axis 52 of the actuating element 42, in particular in order to secure the functional carrier 56 at the recording interface 54 to enable. The receiving interface 54 is preferably arranged on the carrier element 78, in particular formed in one piece with the carrier element 78. A connecting surface 94 of the receiving interface 54, on which the function carrier 56 rests in a state arranged on the receiving interface 54, preferably runs at least substantially perpendicular to the central plane 80.

Preferably, the fixing element 58 can be moved by the actuating element 42 depending on a direction of movement of the actuating element 42. The actuating element 42 is preferably mounted movably along two opposite directions of movement about or along the actuation axis 52. In particular, the actuating element 42, particularly in an embodiment of the actuating element 42 as an actuating lever, is pivotally mounted about the actuating axis 52 along two opposite directions of movement. It is preferred, starting from a securing position of the actuating element 42, in which the fixing element 58 is arranged in a fixing position and the locking element 32, 34 is arranged in the locking position (cf. in particular 2 until 4 ), depending on a movement of the actuating element 42 in one of the directions of movement, the fixing element 58 can be moved into a release position, while the locking element 32, 34 remains in the locking position. Preferably, starting from the securing position of the actuating element 42, in which the fixing element 58 is arranged in the fixing position and the locking element 32, 34 is arranged in the locking position (cf. in particular 2 until 4 ), depending on a movement of the actuating element 42 in another of the directions of movement, the locking element 32, 34 can be moved into a release position, while the fixing element 58 remains in the fixing position. The actuating element 42 is preferably mounted movably relative to the fixing element 58. Preferably, the actuating element 42 can be connected in a rotationally fixed manner to the fixing element 58, in particular in at least one state, by means of a non-positive and/or positive connection. Preferably, the actuating element 42 and the fixing element 58 are dependent on a direction of movement of the actuating element 42 and/or a movement Distance of the actuating element 42 relative to the fixing element 58 can be connected in a force-fitting and / or positive manner, in particular by striking the actuating element 42 on the fixing element 58 and a subsequent further movement of the actuating element 42 along the direction of movement of the actuating element 42, a joint movement of the fixing element 58 together with the Actuating element 42 takes place. However, it is also conceivable that the locking unit 30 comprises a coupling element, by means of which the actuating element 42 can be non-rotatably connected to the fixing element 58 in a non-rotatable and/or positive manner in at least one state. Preferably, depending on a movement of the actuating element 42 along a direction of movement of the actuating element 42, either only the locking element 32, 34 can be moved via the transmission element 44 into a locking position or a release position or only the fixing element 58 can be moved into a fixing position or into a release position.
