Strapping device and method for producing strapped packages
The invention relates to a strapping device and a method for producing strapped packages, which combine at least two articles by at least one strap. The strapping device is paired with a device for providing two or more grouped articles. and the strapping device comprises a handling device ( 10 ) with two pivoting arms ( 11, 12 ) which can be adjusted relative to each other and each of which is equipped with clamping devices ( 14, 15 ) for fixing the belt ends ( 27 ) of a strapping belt ( 26 ) or a strapping blank ( 28 ) in a clamped manner. The pivoting arms ( 11, 12 ) can surround the grouped articles for the purpose of strapping same, thereby pivoting the first pivoting arm ( 11 ) and the second pivoting arm ( 12 ). The strapping device additionally comprises a fixing device for connecting the two belt ends ( 27 ) of the strapping belt ( 26 ) or the strapping blank ( 28 ).
1 . A device for producing finished packaging units ( 30 ) formed from at least two articles ( 20 ) combined by at least one strap, comprising:
a strapping device ( 4 ), comprising:
a handling device ( 10 ) with two pivoting arms ( 11 , 12 ), which can be adjusted relative to each other, and wherein each of the two pivoting arms ( 11 , 12 ) is equipped with clamping devices ( 14 , 15 ) for fixing two belt ends ( 27 ) of a strapping belt ( 26 ) or a strapping blank ( 28 ) in a clamped manner,
wherein a distance between the clamping devices ( 14 , 15 ) in an open state of the two pivoting arms ( 11 , 12 ) corresponds substantially to a length of the strapping belt ( 26 ) or strapping blank ( 27 ) clamped by the clamping devices ( 14 , 15 ),
wherein the two pivoting arms ( 11 , 12 ) pivot and fold to produce an overlapping arrangement of the two belt ends ( 27 ) when the two pivoting arms ( 11 , 12 ) are in a closed state, and to be temporarily connected to one another in the closed state to facilitate pretensioning of the strapping belt ( 26 ) or the strapping blank ( 28 ), and
wherein, during pivoting by the two pivoting arms ( 11 , 12 ), the clamping devices ( 14 , 15 ) move relative to the two pivoting arms, and
a fixing device ( 18 ) for connecting the two belt ends ( 27 ) of the strapping belt ( 26 ) or the strapping blank ( 28 ) to form a finished packaging unit ( 30 ).
2 . The device of claim 1 , wherein the two pivoting arms ( 11 , 12 ) of the strapping device ( 4 ) are pivotably arranged about at least one axis of rotation.
3 . The device of claim 2 , wherein the two pivoting arms ( 11 , 12 ) of the strapping device ( 4 ) are each pivotable about a separate axis of rotation (D 1 , D 2 ).
4 . The device of claim 3 , wherein the two pivoting arms ( 11 , 12 ) of the strapping device ( 4 ) are arranged on a base element ( 13 ) of the handling device ( 10 ).
5 . The device of claim 3 , wherein the two pivoting arms ( 11 , 12 ) of the strapping device ( 4 ) are formed by multi-axis robot arms.
6 . The device of claim 1 , wherein the fixing device ( 18 ) of the strapping device ( 4 ) is arranged on the handling device ( 10 ) or is paired with the handling device ( 10 ).
7 . The device of claim 6 , wherein the fixing device ( 18 ) of the strapping device ( 4 ) comprises a welding unit or an ultrasonic welding unit.
8 . The device of claim 6 , wherein the fixing device ( 18 ) of the strapping device ( 4 ) comprises a gluing unit.
9 . The device of claim 6 , wherein the fixing device ( 18 ) of the strapping device ( 4 ) comprises a device for introducing corresponding incisions or folding edges, located one above the other, into each of the two belt ends ( 27 ) with adjoining folded or bent sections, wherein the folded or bent sections of the belt ends ( 27 ) lying one above the other adjoin each other at least partially and connect the belt ends ( 27 ) to one another in a form-fitting and welded manner at the joint ( 26 ).
