(1) Further advantages will become apparent from the following description of the drawing. In the drawing an exemplary embodiment of the invention is illustrated. The drawing, the description and the claims contain a plurality of features in combination. Someone skilled in the art will purposefully also consider the features separately and will find further expedient combinations.

(3) FIG. 1 a schematic illustration of a detail of a production machine with a packaging transport device according to the invention, and

(4) FIG. 2 a schematic sectional view along a line II-II indicated in FIG. 1.

DETAILED DESCRIPTION

(5) FIG. 1 shows a schematic illustration of a detail of a production machine, in the present case a food packaging machine, with a packaging transport device.

(6) The packaging transport device comprises a support unit 10 having a first support surface 12, which defines a first track section 11, a second support surface 14, which defines a second track section 13, and a third support surface 25, which defines a third track section 24. The second support surface 14 is tilted—relative to the first support surface 12 and to the third support surface 25—around a tilt axis 16 that runs in a transport direction 15.

(7) The packaging transport device comprises a driving member 17, which is embodied by a toothed belt, and drivers 18 which are embodied by individual rods, which are connected to the driving member 17 via plug connections and which are supported movably around the tilt axis 16, this is realized by the driving member 17 being itself implemented so as to be rotatable around the tilt axis 16, and is in particular rotated around the tilt axis 16 between the track sections 11, 13.

(8) The driving member 17 is rotated between the track sections 11, 13 around an axis running within the driving member 17, namely around the tilt axis 16, which has a distance to two edges 19, 20 of the driving member 17 and runs coaxially with a core of the driving member 17.

(9) The driving member 17 is implemented separately from the support unit 10, extends in the transport direction 15 over the track sections 11, 13, 24 and traverses these track sections 11, 13, 24 in operation. The driving member 17 herein runs with the drivers 18 on the support surfaces 12, 14, 25.

(10) During operation, in the track section 11, in which the first support surface 12 is realized having a horizontal extension, product containers are laid on which are not shown in detail. Viewing a certain portion of the driving member 17, which has traversed the track section 11 during operation, this certain portion is firstly rotated around the tilt axis 16 in a first direction, as a result of which the product containers laid thereon are tilted. In the second track section 13, in which the second support surface 14 is realized at a tilt relative to the first support surface 12, the product containers are loaded. When the certain portion of the driving member 17 has passed the second track section 13, this portion is rotated around the tilt axis 16 in a second direction back into its original position, whereupon the product containers laid thereon are tilted back into a horizontal orientation. In the third track section 24, in which the third support surface 25 is oriented horizontally, the product containers are once more oriented horizontally and are advantageously removable. In this way a transition from the first track section 11 with the horizontal first support surface 12 to the second track section 13 with the tilted second support surface 14 is easily realizable. Advantageously the product containers remain positioned between the drivers 18 in accordance with a spacing 21 given by the drivers 18. An error-prone synchronization can be avoided.

(11) A drive of the driving member 17, which is not shown in detail, and a housing accommodating said drive are arranged with a fix orientation relative to form a schematically indicated mounting unit 26 of the packaging transport device and are not tilted with the driving member 17. Via the mounting unit 26, the support unit 10 is mounted on a floor together with its support surfaces 12, 14, 25. Furthermore, schematically shown deflection pulleys 27, 28, via which the driving member 17 is deflected, are mounted on the floor via the mounting unit 26. A tilting mechanism whose synchronization would take a huge effort, like in particular a synchronization of spindles and servomotors, can be avoided.

(12) The driving member 17 is realized so as to be narrower than the support surfaces 12, 14, 25 and is—viewed transversally to the transport direction 15—arranged at least substantially centrally with respect to the support surfaces 12, 14, 25.

(13) The spacing 21 defined by the drivers 18 is adjustable, that is individual drivers 18 can be removed; such that a spacing is achievable in which a distance between two drivers 18 is a multifold in comparison to the spacing 21, in which no drivers 18 have been removed. It is thus advantageously possible to achieve an adaption to product containers having different sizes.

(14) The support unit 10 furthermore comprises a bearing unit 22 (FIG. 2), which is configured to support the second support surface 14 in such a way that it is adjustable in its tilt angle. In order to enable at least semiautomated adjustment, the packaging transport device comprises an actuator 23, which is configured for the adjustment of the tilt angle of the second support surface 14. In order to facilitate an adjustability of the second support surface 14 of the support unit 10 relative to the first support surface 12 of the support unit 10 and to the third support surface 25, the parts of the support unit 10 that forms the support surfaces 12, 14, 25 are interconnected via elongate elements 29, which are supported movably relative to one another. The elongate elements 29 are distinguished by having an extension in their longitudinal direction that is by a multifold larger than their transversal extension. The longitudinal direction of the elongate elements 29 extends substantially parallel to the transport direction 15. Viewed transversally to the transport direction 15, the elongate elements 29 are arranged next to the driving member 17 and also form support surfaces for the product containers and for the drivers 18. The elongate elements 29 are implemented by rods, they could however also be implemented by different elongate elements which are deemed expedient by someone skilled in the art, like for example by tensioned flexurally soft elements, like ropes.
