Abstract: The disclosure relates to a lifting mechanism for opening and closing a tool of a packaging machine. The lifting mechanism comprises at least one first lifting device and at least one second lifting device which can be actuated in succession in order to move the lifting mechanism from an open position to a closed position, wherein the first lifting device is decoupled from a load absorption caused by means of the second lifting device for closing the tool. The lifting mechanism comprises at least one adjustable locking mechanism for force-related decoupling of the first lifting device from a force flow caused by the second lifting device. Furthermore, the disclosure relates to a corresponding method.

Abstract: A thermoforming packaging machine includes a forming station for thermoforming troughs in a film web, a filling path for filling products into the troughs, a sealing station for sealing the troughs, a chain guide for guiding a transport chain for the film web, a transverse cutting device for cutting the film web in a direction transverse to the transport direction, a longitudinal cutting device for cutting the film web in the transport direction, and a control device for controlling processes running on the thermoforming packaging machine. The transverse cutting device comprises a film punch, an adjustment drive which can be controlled by the control device for closing and opening the film punch, and a detection unit which is connected to the control device and which has at least one sensor which is configured to detect, per processing cycle, a force progression occurring at the film punch during opening and closing.

Abstract: The disclosure relates to a lifting gear for opening and closing a workstation of a packaging machine, wherein the lifting gear includes a stationarily mounted base, a lifting platform mounted to be height adjustable with respect to the base along a lifting axis for supporting a lower tool part of the workstation, and an adjusting mechanism comprising a drive unit and a toggle means on which the lifting platform is mounted, wherein the adjusting mechanism furthermore includes a pressure part coupled with the toggle means and adjustable by means of the drive unit along the lifting axis, wherein by the displacement of said pressure part along the lifting axis, the toggle means can be actuated for a height adjustment of the lifting platform.

Abstract: A packaging machine having a plurality of working stations for processing a film, at least one of the working stations being a cutting station. The working stations are disposed successively along a working direction and the film is conveyed in the working direction from a first one of the working stations to a second one of the working stations. The cutting station is configured to sever the film in a cutting direction, which is oriented transverse, preferably orthogonal, with respect to the working direction. The cutting station has a knife and counter pressure device, both being pressable against one another in a pressing direction. The disclosure is characterized in that the counter pressure device has a curved surface, which is curved around a curvature axis, and the counter pressure device is configured to roll on a cutting edge of the knife about a rolling axis with the curved surface.
