Device for strapping

Abstract

The invention is related to a strapping device ( 1 ) for the strapping of an object ( 14 ) with a strapping tape ( 5 ). The strapping device ( 1 ) comprises a means of guidance ( 3 ) for guiding a strapping tape ( 5 ), which serves for the purpose of forming a loop of strapping tape ( 5 ) in a waiting position. The formation of the loop takes place independently of the position of the object to be strapped ( 14 ). The strapping device ( 1 ) furthermore comprises a means for movement of the loop ( 4 ). This means serves for positioning the loop of strapping tape ( 5 ) formed by the means of guidance ( 3 ) from the waiting position into a stacking position around an object ( 14 ) to be strapped, after this object has been positioned on a work surface ( 2 ).

1 . Strapping device ( 1 ) for the strapping of an object ( 14 ) with a means of strapping ( 5 ), characterised in that the strapping device ( 1 ) comprises a means of guidance ( 3 ) for guiding the strapping means ( 5 ), which means of guidance ( 3 ) serves for the formation of a loop of means of strapping ( 5 ) in a waiting position, independent of the position of the object to be strapped ( 14 ), and that a loop movement means ( 4 ) is present, which serves to position the loop of strapping means ( 5 ) formed by the means of guidance ( 3 ) from the waiting position in a stacking position around an object to be strapped ( 14 ).  
     
     
         2 . Strapping device ( 1 ) in accordance with  claim 1 , characterised in that the means of guidance ( 3 ) is a groove ( 3 ) embedded in a work surface ( 2 ), in which the means of strapping ( 5 ) is able to be pushed in, and that the loop movement device ( 4 ) comprises at least one arm ( 1 ) projecting from the work surface ( 2 ) with at least one gripper ( 12 ), which is arranged to be displaceable under control along the at least one arm ( 11 ) and which serves as driving means for moving the loop of strapping means ( 5 ) from the waiting position into the stacking position.  
     
     
         3 . Strapping device ( 1 ) according to  claim 2 , characterised in that the at least one arm ( 11 ) is curved.  
     
     
         4 . Strapping device ( 1 ) in accordance with  claim 2  or  3 , characterised in that the at least one arm ( 11 ) is arranged to be movable relative to the work surface ( 2 ).  
     
     
         5 . Strapping device ( 1 ) according to one of the  claims 2  to  4 , characterised in that the at least one gripper ( 12 ) comprises an opening with a substantially U-shaped or O-shaped, laterally slotted cross section, which serves for the temporary taking hold of and moving of the means of strapping ( 5 ) and which is designed in such a manner, that it can release the means of strapping ( 5 ) in a stacking position.  
     
     
         6 . Strapping device ( 1 ) in accordance with one of the  claims 2  to  5 , characterised in that in the interior of the arm ( 11 ) a movable, driven wire string is arranged, which is connected with the at least one gripper ( 12 ) and which serves for driving it.  
     
     
         7 . Strapping device ( 1 ) according to one of the  claims 2  to  6 , characterised in that the strapping device ( 1 ) comprises at least one electric motor and/or one compressed air motor and/or one hydraulic motor and/or one solenoid motor and/or one piezo-electric motor, which serves or which serve for driving the at least one gripper ( 12 ).  
     
     
         8 . Strapping device ( 1 ) in accordance with one of the  claims 2  to  7 , characterised in that the strapping device ( 1 ) comprises precisely two arms ( 11 ) each respectively with one gripper arranged to be controllably movable along it.  
     
     
         9 . Strapping device ( 1 ) according to one of the  claims 2  to  8 , characterised in that the means of guidance ( 3 ) extends essentially along the edges of a rectangle.  
     
     
         10 . Strapping device ( 1 ) in accordance with one of the  claims 2  to  9 , characterised in that the groove ( 3 ) is closed off by means of elastic elements.
