Abstract

The invention discloses a method for producing packaging units and the produced packaging units, comprising at least two substantially similar articles, wherein the articles are held together by at least one packaging blank ( 14 ). A main surface of the packaging blank ( 14 ) is applied to first end faces of an article grouping ( 20 ), forming a connection between the articles and primary fixing element of the packaging blank ( 14 ). The primary fixing element fixes the positions of the articles relative to one another. The side surfaces ( 24 ) of the packaging blank ( 14 ) are subsequently folded over, wherein secondary fixing element interacts with the shell surfaces of the articles. The secondary fixing elements are formed by strapping sections, which surround the article grouping ( 20 ) and fixes the articles in a substantially parallel alignment to one another. The invention also relates to a packaging device for carrying out the method.

an application device ( 176 ) capable of applying a main surface ( 18 ) of at least one packaging blank ( 14 ) to one or more first end faces ( 16 ) of the at least two article or grouped articles ( 20 ) and capable of establishing a connection between the articles ( 12 ) and a primary fixing element ( 22 ) of the packaging blank ( 14 ), wherein the application device ( 176 ) comprises at least one controllable application head ( 130 ) capable of moving within a defined movement space,
wherein the at least one controllable application head ( 130 ) can apply a packaging blank ( 14 ) to at least one article grouping ( 20 ) located or moving within the movement space,
wherein the at least one controllable application head ( 130 ) is capable of receiving, holding, and releasing the packaging blanks ( 14 ) and capable of placing the respective packaging blank ( 14 ) on an upper side of the respective article grouping ( 20 ),
a shaping device ( 60 , 158 ) capable of folding over at least one side surface ( 24 ) adjacent to a longitudinal side of the main surface ( 18 ) of the packaging blank ( 14 ), thus forming a secondary fixing element ( 30 ) interacting with one or more shell surfaces ( 26 ) of the articles ( 12 ), and
a fixing device ( 178 , 180 ) capable of forming the secondary fixing elements ( 30 ) formed by strapping sections ( 32 ), which strapping sections ( 32 ) surround defined regions of the shell surfaces ( 26 ) of the articles ( 12 ) and fixes the articles ( 12 ) in a parallel or an approximately parallel alignment to one another.

2. The packaging device of claim 1 , wherein the receiving device comprises at least one suction device.

3. The packaging device of claim 1 , wherein the at least one controllable application head ( 130 ) comprises two or more application units ( 132 ) capable of synchronously or approximately synchronously equipping two or more separate article groupings ( 20 ) with packaging blanks ( 14 ).

4. The packaging device of claim 1 wherein each of the at least one controllable application unit ( 132 ) comprises a contact plate ( 144 ) capable of moving vertically between two end positions, and comprises at least one controllable suction element ( 138 ).

5. The packaging device of claim 1 wherein each of the at least one controllable application unit ( 132 ) comprises a shaping element ( 202 ) capable of deforming a defined folding region ( 46 ) of a packaging blank ( 14 ) placed on a respective article grouping ( 20 ) and thus form the primary fixing element ( 22 ) establishing mechanical connections between the articles ( 12 ) and the packaging blank ( 14 ).

6. The packaging device of claim 1 wherein each of the at least one controllable application unit ( 132 ) comprises folding elements ( 158 ) capable of folding over side surfaces ( 24 ) of the packaging blank ( 14 ) and of preparing the secondary fixing element ( 30 ) between the article grouping ( 20 ) and the packaging blank ( 14 ).

7. The packaging device of claim 6 , wherein the contact plate ( 144 ), one or more suction elements ( 138 ), the folding elements ( 158 ), and the shaping element ( 202 ) of each application unit ( 132 ) are capable, in conjunction with the application head ( 130 ), of being be lowered onto the article grouping ( 20 ) or lifted therefrom.

8. A method for producing packaging units ( 10 ), comprising at least two articles ( 12 ), wherein the at least two articles ( 12 ) are held together by at least one packaging blank ( 14 ), comprising:
taking at least one packaging blank ( 14 ) from a stockpile or from a magazine ( 234 ) by an application head ( 130 ), holding ready in the application head ( 130 ), and applying the at least one packaging blank ( 14 ), by lowering the application head ( 130 ), to an article grouping ( 20 ), thus forming a primary fixing element ( 22 ),
applying a main surface ( 18 ) of the packaging blank ( 14 ) to one or more first end faces ( 16 ) of a group of articles ( 12 ), forming a connection between the grouped articles ( 12 ) and the primary fixing element ( 22 ) of the packaging blank ( 14 ), which the primary fixing element ( 22 ) fixes positions of the articles ( 12 ) relative to one another,
folding over at least one side surface ( 24 ) adjacent to a longitudinal side of the main surface ( 18 ) of the packaging blank ( 14 ), forming a secondary fixing element ( 30 ) interacting with one or more shell surfaces ( 26 ) of the articles ( 12 ),
wherein the secondary fixing element ( 30 ) are formed by one or more strapping sections ( 30 ) that surround defined regions of the one or more shell surfaces ( 26 ) of the articles ( 12 ) and fixes the articles ( 12 ) in a parallel or an approximately parallel alignment to one another.

9. The method of claim 8 , wherein two side surfaces ( 24 ) adjacent to opposite longitudinal sides of the main surface ( 18 ) of the packaging blank ( 14 ) are folded over, forming secondary fixing element ( 30 ) interacting with one or more shell surfaces ( 26 ) of the articles ( 12 ).

10. The method of claim 8 , wherein the strapping sections ( 32 ) of the secondary fixing element ( 30 ) are formed by strip sections ( 28 ) of the packaging blank ( 14 ) that extend one or more side faces ( 24 ) in directions along the longitudinal extension directions of the side faces ( 24 ).

11. The method of claim 10 , wherein the one or more side surfaces ( 24 ) and the strip sections ( 28 ) are folded over by one or more handling devices ( 56 ) and reshaped into strapping sections ( 32 ), wherein one or more overlapping end regions are fixed to one another or to the one or more shell surfaces ( 26 ) of the articles ( 12 ).

12. The method of claim 8 , wherein the main surface ( 18 ) of the packaging blank ( 14 ) is reshaped, folded, or notched in a region between bordering articles ( 12 ), wherein adjacent primary fixing element ( 22 ), together with the articles ( 12 ) held therein, are brought closer to one another until the adjacent articles ( 12 ) are in touching contact.

13. The method of claim 8 , wherein the application head ( 130 ) is moved within a movement space between a stockpile, a supply point, or a magazine ( 234 ) for the flat packaging blanks ( 14 ) and the article grouping ( 20 ).

14. The method of claim 8 , wherein the application head ( 130 ) comprises at least two modular application units ( 132 ) are located next to one another, as a result of which two similar article groupings ( 20 ) can be processed or handled in parallel and equipped with packaging blanks ( 14 ).

15. The method of claim 8 , further comprising lowering a flat contact plate ( 144 ) in the respective application unit ( 132 ), while at the same time deactivating a negative pressure on suction elements ( 138 ) that holds the packaging blank ( 14 ) in place in the respective application unit ( 132 ), or lowering the contact plate ( 144 ) relative to the suction elements ( 138 ) located in a fixed position in the respective application unit ( 132 ) of the application head ( 130 ), as a result of which the packaging blank ( 14 ) is spaced apart from the suction elements ( 138 ) and detached.
