Abstract

Claims (24)

1 . A packaging apparatus for combining a plurality of articles by an outer packaging formed from a packaging blank, comprising:

a magazine ( 12 ) with several flat packaging blanks ( 10 ) stacked on top of one another, wherein the packaging blanks ( 10 ) are arranged in the magazine ( 12 ) stacked on top of one another or with their flat sides joined together,

a removal apparatus ( 8 ) for the individual removal of packaging blanks ( 10 ) from the magazine ( 12 ), which removal apparatus ( 8 ) is equipped with a horizontally and vertically movable handling device ( 16 ) with tools arranged thereon, wherein the tools include at least a clamping bracket ( 22 ) and a gripping device ( 30 ),

wherein the clamping bracket ( 22 ) is capable of pressing on and fixing the stack ( 14 ) of packaging blanks ( 10 ), in a first surface region ( 24 ),

wherein the gripping device ( 30 ) is capable of taking hold of a packaging blank ( 10 , 10 - 1 ) that is uppermost in the stack ( 14 ) or situated at the edge of the stack ( 14 ), in a second surface region ( 32 ) adjoining the first surface region ( 24 ), wherein the gripping device ( 30 ) is mounted pivotably on the handling device ( 16 ),

wherein the gripping device ( 30 ) comprises at least one suction plunger ( 34 ) or at least one other gripper operating with suction pressure, wherein the suction plunger or plungers ( 34 ) can be subjected to variably adjustable negative pressure,

wherein the gripping device ( 30 ) with the at least one suction plunger ( 34 ) is angle-adjustably or otherwise movably mounted relative to the clamping bracket ( 22 ),

and wherein the gripping device ( 30 ) can be pivoted during lifting or after lifting of the uppermost gripped packaging blank ( 10 , 10 - 1 ) from the stack ( 14 ) such that the second surface region ( 32 ) can be angled towards the fixed first surface region ( 24 ) to separate the gripped packaging blank ( 10 , 10 - 1 ) from the stack ( 14 ) after releasing the clamping bracket ( 22 ), and to remove it from the magazine ( 12 ) by lifting the handling device ( 16 ).

2 . The packaging apparatus of claim 1 , wherein the clamping bracket ( 22 ) is placed or pressed onto the first surface region ( 24 ) of the packaging blank ( 10 , 10 - 1 ) by an infeed movement of the handling device ( 16 ).

3 . The packaging apparatus of claim 2 , wherein the handling device ( 16 ) has a gantry suspension ( 18 ) or another movable suspension and can thus be lifted and lowered or fed towards the stack ( 14 ) and lifted away from the stack ( 14 ).

4 . A method for removing individual flat packaging blanks ( 10 , 10 - 1 , 10 - 2 , 10 - 3 ) from a magazine ( 12 ) with several stacked packaging blanks ( 10 ), comprising:

fixing, in a first surface region ( 24 ) of a packaging blank ( 10 , 10 - 1 ) and pressing into the magazine ( 12 ), the packaging blank ( 10 , 10 - 1 ) situated at the edge of or uppermost on the stack ( 14 ) by placing or pressing a clamping bracket ( 22 ) on the first surface region ( 24 ), and

gripping by a gripping device ( 30 ) in a second surface region ( 32 ) adjoining the first surface region ( 24 ), wherein the gripping device ( 30 ) is mounted or pivotably mounted on a handling device ( 16 ) and comprises at least one suction plunger ( 34 ) or at least one other gripper operating with suction pressure, and wherein the gripping device ( 30 ) with the at least one suction plunger ( 34 ) is angle-adjustably or otherwise movably mounted relative to the clamping bracket ( 22 ),

lifting the gripped packaging blank ( 10 , 10 - 1 ) from the stack ( 14 ) in the second surface region ( 32 ) and angled towards the fixed first surface region ( 24 ),

releasing the first surface region ( 24 ) of the packaging blank ( 10 , 10 - 1 ), and then separating the gripped packaging blank ( 10 , 10 - 1 ) from the stack ( 14 ) and removing it from the magazine ( 12 ).

5 . The method of claim 4 , further comprising carrying out the fixing step and the gripping with a handling device ( 16 ), wherein the handling device ( 16 ) is capable of being lifted and lowered or is capable of being fed towards the stack ( 14 ) and lifted away from the stack ( 14 ).

6 . The method of claim 5 , wherein the handling device ( 16 ) comprises a gantry suspension ( 18 ) or another movable suspension.

7 . The method of claim 4 , further comprising subjecting the suction plunger or plungers ( 34 ) of the gripping device ( 30 ) to a variably adjustable negative pressure.

8 . The method of claim 4 , further comprising deforming the packaging blank ( 10 , 10 - 1 ) by pivoting the gripping device ( 30 ) with the clamping device or clamping bracket ( 22 ) fixed, and lifting off at least on one side of the packaging blank ( 10 , 10 - 1 ) from the stack ( 14 ).

9 . The method according to claim 8 , wherein the deforming step comprises detaching or peeling off the gripped packaging blank ( 10 , 10 - 1 ) from the adjoining packaging blank ( 10 , 10 - 2 ).

10 . A removal apparatus ( 8 ) for the individual removal of packaging blanks ( 10 ) from a magazine ( 12 ) comprising a horizontally and vertically movable handling device ( 16 ) with tools arranged thereon, wherein the tools include at least a clamping bracket ( 22 ) and a gripping device ( 30 ),

wherein the clamping bracket ( 22 ) is capable of pressing on and fixing the stack ( 14 ) of packaging blanks ( 10 ), in a first surface region ( 24 ),

wherein the gripping device ( 30 ) is capable of taking hold of a packaging blank ( 10 , 10 - 1 ) that is uppermost in the stack ( 14 ), in a second surface region ( 32 ) adjoining the first surface region ( 24 ),

and wherein the gripping device ( 30 ) can be pivoted during lifting or after lifting of the uppermost gripped packaging blank ( 10 , 10 - 1 ) in the second surface region ( 32 ) from the stack ( 14 ) such that the second surface region ( 32 ) can be angled towards the fixed first surface region ( 24 ) to separate the gripped packaging blank ( 10 , 10 - 1 ) from the stack ( 14 ) after releasing the clamping bracket ( 22 ), and to remove it from the magazine ( 12 ) by lifting the handling device ( 16 ).
