  • Patent number: 10618766
    Abstract: Gripping device adapted for gripping a stack of flat-folded cartons, where the gripping device comprises a first gripping jaw and a second gripping jaw arranged adjacent each other and enclosing a holding space, where the gripping device is provided with a first open state in which the distance between the gripping jaws is greater than the height of a flat-folded carton, and where the gripping device is provided with a second closed state in which the distance between the gripping jaws is less than the height of a flat-folded carton, and that the gripping device is adapted to displace one side of the stack of flat-folded cartons in a longitudinal direction, such that each flat-folded carton of the stack of flat-folded cartons will be held in an angled state by the gripping device. The advantage of the invention is that a stack of flat-folded cartons can be held in a secure way, where the height of the stack is reduced when the stack is held.

  • Patent number: 9097610
    Abstract: The invention relates to a method and an arrangement for detecting a leak in a sealed package containing a product in the form of a foodstuff or a pharmaceutical. The leak detecting arrangement comprises a testing station, in which a package is placed by the transporting means and a pressure applying means arranged to apply a predetermined amount of pressure on the package located in the testing station. The arrangement further comprises a continuously operated suction means arranged to draw ambient air past a seal on the packet to be tested and a gas sensor located in the flow of ambient air drawn off by the suction means and arranged to transmit a signal dependent on the test gas concentration detected in the ambient air.

  • Patent number: 8413790
    Abstract: The invention relates to a method for synchronizing, and a transfer device for synchronizing, a movement pattern between two units in a packaging line, wherein one unit is intermittently operated and the second unit is continuously operated. The invention is particularly intended for a transfer device between an intermittently operated filler unit and a continuously operated cartoning machine. The transfer device is provided with a frame (13) arranged to support tube pickers-/placers (28) and is arranged to perform a simultaneous pivoting movement about a first and a second shaft (16, 31), and for rotation about a third shaft (48) at right angles to the second shaft (31). The frame is further provided with means for adjusting the spacing between the tubes and means for compensating for differences in vertical position during the rotating movement in the case where the containers picked from the part circular conveyor of the filling unit.
