Abstract

The invention relates to a packaging machine ( 100 ) for arranging elements, preferably cartons (K), on pallets (Z), wherein the packaging machine ( 100 ) has the following: a palletizing station ( 180 ) that has a platform ( 181 ) and a Scara robot ( 182 ), which is positioned on the platform ( 181 ) and which is embodied to move elements, preferably cartons (K), to be stowed on pallets (Z); a pallet feed ( 190 ), which is embodied to feed empty pallets (Z) along a path, wherein the platform ( 181 ) is embodied in a bridge-like manner and the path extends through under the platform ( 181 ) of the palletizing station ( 180 ) to a pallet loading station ( 191 ).

First claim

What is claimed is:

1. A packaging machine ( 100 ) for arranging elements, preferably cartons (K), on pallets (Z), wherein the packaging machine ( 100 ) comprises:
a palletizing station ( 180 ) that has a platform ( 181 ) and a Scara robot ( 182 ), which is positioned on the platform ( 181 ) and which is configured to move elements, preferably cartons (K), to be stowed on pallets (Z);
an upstream carton closing station ( 170 ) at which an open carton (K) is folded and/or glued to form a closed carton (K)
an upstream labeling apparatus ( 150 ) to provide the elements with a label, wherein the labeling apparatus ( 150 ) is positioned at least substantially below the carton closing station ( 170 ); and
a pallet feed ( 190 ), which is configured to feed empty pallets (Z) along a path, wherein the platform ( 181 ) is embodied in a bridge-like manner and the path extends through under the platform ( 181 ) of the palletizing station ( 180 ) to a pallet loading station ( 191 ).

2. The packaging machine ( 100 ) according to claim 1 , wherein the platform ( 181 ) serves as an intermediate store for elements to be stowed on pallets (Z).

3. The packaging machine ( 100 ) according to claim 1 , wherein the area of the platform ( 181 ) is greater than the area of a pallet (Z).

4. The packaging machine ( 100 ) according to claim 1 , wherein the Scara robot ( 182 ) has a main body ( 186 ), an upper arm ( 183 ), and a lower arm ( 184 ), the upper arm ( 183 ) being fastened to the main body ( 186 ) so that it can be rotated around a first axis of rotation and the lower arm ( 184 ) being fastened to the upper arm ( 183 ) so that it can be rotated around a second axis of rotation that extends parallel to the first axis of rotation, and the Scara robot ( 182 ) also having a control that is embodied so that it permits the lower arm ( 184 ) to cross the upper arm ( 183 ).

5. The packaging machine ( 100 ) according to claim 1 , wherein the pallets (Z) are loaded, preferably automatically, onto the pallet feed ( 190 ) by means of forklift trucks and unloaded by the pallet loading station ( 191 ).

6. The packaging machine ( 100 ) according to claim 1 , wherein the elements are cartons (K) and wherein, upstream of the palletizing station ( 180 ), the packaging machine ( 100 ) further comprises:
a product feed ( 110 ) for feeding products ( 0 ) to be packaged in cartons (K);
a carton magazine ( 120 ) wherein a plurality of preferably glued carton blanks are arranged at least substantially flat; and
a stationary erecting station ( 130 ) for erecting carton blanks in a stationary manner to form at least substantially block-shaped open cartons (K), wherein the product feed ( 110 ) has an at least substantially horizontal first conveying direction and wherein the erecting station ( 130 ) is positioned next to the carton magazine ( 120 ) in a direction perpendicular to the first conveying direction.

7. The packaging machine ( 100 ) according to claim 6 , wherein the carton magazine ( 120 ) is positioned above the product feed ( 110 ) in such a way that the product feed ( 110 ) guides the products (O) through under the carton magazine ( 120 ).

8. The packaging machine ( 100 ) according to claim 6 , wherein the product feed ( 110 ) has a stacking apparatus ( 111 ) that is configured to at least stack a first group of products (O) vertically above or below a second group of products (O).

9. The packaging machine ( 100 ) according to claim 8 , wherein the stacking apparatus ( 111 ) is also embodied to convey the stacked groups of products (O) from a lower level to a vertically higher upper level, wherein the products (O) are fed to the stacking apparatus ( 111 ) in the first conveying direction and conveyed onward from the stacking apparatus ( 111 ) in a second conveying direction, and wherein the second conveying direction is at least substantially opposite from the first conveying direction.

10. A method for arranging elements, preferably cartons (K), on pallets (Z) with the aid of a packaging machine ( 100 ) according to claim 1 .

11. The method for arranging elements, preferably cartons (K), on pallets (Z) according to claim 10 , wherein the method has the following step:
actuation of the Scara robot ( 182 ) in such a way that the lower arm ( 184 ) crosses the upper arm ( 183 ).

12. A packaging machine ( 100 ) for arranging elements, preferably cartons (K), on pallets (Z), wherein the packaging machine ( 100 ) comprises:
a product feed ( 110 ) for feeding products (O) to be packaged in cartons (K), wherein the product feed ( 110 ) has a stacking apparatus ( 111 ) that is configured to at least stack a first group of products (O) vertically above or below a second group of products (O) and wherein the stacking apparatus is configured to convey the stacked groups of products (O) from a lower level to a vertically higher upper level, wherein the products (O) are fed to the stacking apparatus ( 111 ) in the first conveying direction and conveyed onward from the stacking apparatus ( 111 ) in a second conveying direction, and wherein the second conveying direction is at least substantially opposite from the first conveying direction;
a carton magazine ( 120 ) wherein a plurality of preferably glued carton blanks are arranged at least substantially flat;
a stationary erecting station ( 130 ) for erecting carton blanks in a stationary manner to form at least substantially block-shaped open cartons (K), wherein the product feed ( 110 ) has an at least substantially horizontal first conveying direction and wherein the erecting station ( 130 ) is positioned next to the carton magazine ( 120 ) in a direction perpendicular to the first conveying direction;
a palletizing station ( 180 ) that has a platform ( 181 ) and a Scara robot ( 182 ), which is positioned on the platform ( 181 ) and which is configured to move elements, preferably cartons (K), to be stowed on pallets (Z); and
a pallet feed ( 190 ), which is configured to feed empty pallets (Z) along a path, wherein the platform ( 181 ) is embodied in a bridge-like manner and the path extends through under the platform ( 181 ) of the palletizing station ( 180 ) to a pallet loading station ( 191 ).

13. The packaging machine ( 100 ) according to claim 12 , wherein the packaging machine ( 100 ) also has an upstream labeling apparatus ( 150 ) that is embodied to provide the elements with a label, preferably from below.

14. The packaging machine ( 100 ) according to claim 13 , wherein the elements are cartons (K) and wherein the packaging machine ( 100 ) also has an upstream carton closing station ( 170 ) at which an open carton (K) is folded and/or glued to form a closed carton (K).

15. The packaging machine ( 100 ) according to claim 14 , wherein the labeling apparatus ( 150 ) is positioned together with a carton turning station ( 175 ) that is configured to turn cartons (K).
